TECHNICAL FIELD

The present disclosure relates to the technical field of carriers, and particularly relates to a child carrier or a pet carrier.

BACKGROUND

Most of the current carrying devices on the market, such as infant car seats or pet carrier baskets, etc., can be detachably connected to a frame body (e.g., the chair frame of a highchair or the stroller frame of a stroller). However, the operation process of detaching the carrying device from the frame body is often inconvenient. The user needs to continuously perform an unlocking operation with both hands during this process to ensure the carrying device is unlocked from the frame body, and then can remove the carrying device from the frame body, which is very troublesome.

SUMMARY

Accordingly, it is necessary to provide a carrier in which the process of detaching the carrying device from the frame body is more convenient.

A carrier is provided, which includes a frame body, a carrying device, a locking mechanism and a holding mechanism. The carrying device is detachably mounted on the frame body. The locking mechanism is movably provided on one of the frame body and the carrying device, and switchable between a locked state and an unlocked state. The locking mechanism locking the frame body and the carrying device when the locking mechanism is in the locked state. The carrying device is capable of separating from the frame body when the locking mechanism is in the unlocked state. The holding mechanism is movably provided on one of the carrying device and the frame body and having a first avoidance state and a holding state. When the carrying device and the frame body are connected to each other, the holding mechanism is located between the locking mechanism and the other one of the carrying device and the frame body. When the carrying device and the frame body are connected to each other and the locking mechanism is in the locked state, the holding mechanism deviates from a moving path of the locking mechanism, the holding mechanism is in the first avoidance state, and the locking mechanism is capable of switching from the locked state to the unlocked state relative to the holding mechanism. When the carrying device and the frame body are connected to each other and the locking mechanism is in the unlocked state, the holding mechanism is located on the moving path of the locking mechanism, the holding mechanism is in the holding state, and the holding mechanism maintains the locking mechanism in the unlocked state.

One of the aforementioned carrying device and frame body is provided with the locking mechanism and the holding mechanism. The locking mechanism is switchable between the locked state and the unlocked state to control the locking and separation of the carrying device and the frame body. The holding mechanism is switchable between the first avoidance state and the holding state. When the carrying device and the frame body are connected to each other and the locking mechanism is in the locked state, the holding mechanism deviates from the moving path of the locking mechanism, the locking mechanism is movable relative to the holding mechanism, the holding mechanism is in the first avoidance state at this time, and the locking mechanism is capable of switching from the locked state to the unlocked state. When the carrying device and the frame body are connected to each other and the locking mechanism is in the unlocked state, the holding mechanism is located on the moving path of the locking mechanism, the holding mechanism is in the holding state, and the locking mechanism is maintained in the unlocked state. As such, when it is necessary to detach the carrying device from the frame body, after the user unlocks the locking mechanism, the holding mechanism is capable of maintaining the locking mechanism in the unlocked state, such that the user can remove the carrying device from the frame body without continuously performing the unlocking operation, which is convenient to use.

In one of the embodiments, the holding mechanism includes a holding member, a holding seat drivingly connected to the holding member, and a first reset member located between the holding member and the holding seat.

These directional terms are only used to make the description of the embodiments of the present disclosure clearer and are not intended to improperly limit the protection scope of the present disclosure.

As shown in FIG. 1 to FIG. 3, the carrying device 100 includes a carrying body 110 and a fixing seat 120. The carrying body 110 includes a support plate 111, a support frame 112, a connecting member 113, and a covering material (not shown in the figures) for covering the support plate 111, the support frame 112, and the connecting member 113. The support plate 111 and the support frame 112 are spaced apart, and there are a plurality of connecting members 113 respectively connected between the support plate 111 and the support frame 112. The support plate 111 may be substantially a square plate-like structure, and the support frame 112 may be a square frame structure. There may be four connecting members 113, two of which are oppositely arranged on the left side and the right side of the support plate 111 and the support frame 112 respectively, and the other two connecting members 113 are oppositely arranged on the front side and the rear side of the support plate 111 and the support frame 112. Optionally, there may be two connecting members 113, which are oppositely arranged on the left side and the right side of the support plate 111 and the support frame 112. A handle 130 may further be provided above the support frame 112 to facilitate carrying the carrying device 100. The handle 130 may have, for example, a U-shaped rod structure, with both ends of the handle 130 respectively connected to the left side and the right side of the support frame 112. There are two fixing seats 120 respectively provided on the left side and the right side of the carrying body 110. The two fixing seats 120 may be respectively provided at the connecting members 113 located on the left side and the right side, for example. Taking one of the fixing seats 120 as an example, the fixing seat 120 is connected to an end of the connecting member 113 away from the support frame 112 and to the support plate 111.

Continuing to refer to FIG. 1 to FIG. 3, the frame body 200 includes a support frame 210 and an engagement seat 220. There are two engagement seats 220 respectively arranged on the left side and the right side of the support frame 210. The support frame 210 may include, for example, a front bracket 211, a rear bracket 212, and a connecting frame 213. The front bracket 211 has a substantially U-shaped frame structure, including a front cross rod 2111 and two front side rods 2112 connected to both ends of the front cross rod 2111 respectively. Ends of the two front side rods 2112 away from the front cross rod 2111 are respectively pivotally connected to the two engagement seats 220. The rear bracket 212 has a substantially U-shaped frame structure, including a rear cross rod 2121 and two rear side rods 2122 connected to both ends of the rear cross rod 2121 respectively. Ends of the two rear side rods 2122 away from the rear cross rod 2121 are respectively pivotally connected to the two engagement seats 220. The connecting frame 213 is substantially a square frame structure, including a first side rod 2131 and a second side rods 2132 oppositely arranged, and a first cross rod 2133 and a second cross rod 2134 connected between the first side rod 2131 and the second side rod 2132. Both ends of the first side rod 2131 are respectively pivotally connected to the front side rod 2112 and the rear side rod 2122 located on one side of the support frame 210, and both ends of the second side rod 2132 are respectively pivotally connected to the front side rod 2112 and the rear side rod 2122 located on the other side of the support frame 210. In some embodiments, the first side rod 2131 may further include two first rod portions 2131a pivotally connected to each other, and the second side rod 2132 may include two second rod portions 2132a pivotally connected to each other. As such, when it is necessary to fold or transport the frame body 200, the two first rod portions 2131a may be pivoted and collapsed relative to each other, and the two second rod portions 2132a may be pivoted and collapsed relative to each other, enabling the front bracket 211 and the rear bracket 212 to approach and fold towards each other, thereby reducing the overall volume of the frame body 200.

In some embodiments not shown, the support frame 210 may also be in a non-foldable form. In this case, the two front side rods 2112 and the two rear side rods 2122 may be directly fixedly connected to the two fixing seats 120, respectively, and the first side rod 2131 and the second side rod 2132 may also be directly connected to the two front side rods 2112 and the two rear side rods 2122, respectively. The first side rod 2131 and the second side rod 2132 may be integrally formed straight rods without including two pivotally connected rod portions.

In some embodiments not shown, the connecting frame 213 in the support frame 210 may also be omitted while ensuring sufficient stability of the support frame 210. That is, the support frame 210 may only include the front bracket 211 and the rear bracket 212.

Continuing to refer to FIG. 1 to FIG. 3, the fixing seat 120 and the engagement seat 220 are selectively engaged with each other to achieve detachable connection between the carrying device 100 and the frame body 200. Specifically, an outer side surface of the fixing seat 120 is provided with an engagement protrusion 1211, and a surface of the engagement seat 220 facing another engagement seat 220 may be provided with an engagement recess 221. The engagement protrusion 1211 and the engagement recess 221 may be engaged by insertion. Specifically, the engagement recess 221 penetrates a top surface of the engagement seat 220. When the carrying device 100 is mounted on the frame body 200, the engagement protrusion 1211 may be inserted into the engagement recess 221 via the penetrating opening on the top surface of the engagement seat 220.

In some embodiments not shown, the arrangement positions of the engagement protrusion 1211 and the engagement recess 221 may also be reversed. That is, the engagement protrusion 1211 is provided on the engagement seat 220, and the engagement recess 221 is provided on the fixing seat 120.

Further, as shown in FIG. 2 and FIG. 3, the carrier may further include a locking mechanism 300 and a lock-engaging portion 320. The locking mechanism 300 has a locked state and an unlocked state and is switchable between the locked state and the unlocked state. The locking mechanism 300 locks the frame body 200 and the carrying device 100 when the locking mechanism 300 is in the locked state; the carrying device 100 may be separated from the frame body 200 when the locking mechanism 300 is in the unlocked state. The locking mechanism 300 is movably provided on one of the carrying device 100 and the frame body 200. The lock-engaging portion 320 is provide on the other one of the carrying device 100 and the frame body 200. As shown in FIG. 2 and FIG. 3, specifically, the locking mechanism 300 may be movably provided on the carrying device 100. The locking mechanism 300 includes a locking member 310 (see FIG. 11), and the locking member 310 is switchable between a locked position and an unlocked position. Since the locking mechanism 300 can be movably provided on the carrying device 100, it is understood that the locking member 310 can also be movably provided on the carrying device 100. Specifically, the locking member 310 is movably provided on the fixing seat 120 of the carrying device 100, while the lock-engaging portion 320 is provided on the engagement seat 220 of the frame body 200. In embodiments not shown, the locking mechanism 300 may also be movably provided on the frame body 200. The locking member 310 may be movably provided on the engagement seat 220 of the frame body 200, and the lock-engaging portion 320 may be provided on the fixing seat 120 of the carrying device 100. When the locking mechanism 300 is in the locked state, the locking member 310 is in the locked position, and the locking member 310 is engaged and locked with the lock-engaging portion 320, thereby locking the connection between the carrying device 100 and the frame body 200. When the locking mechanism 300 is in the unlocked state, the locking member 310 is in the unlocked position, and the locking member 310 is disengaged from the lock-engaging portion 320, thereby releasing the lock between the carrying device 100 and the frame body 200, allowing the carrying device 100 to be separated from the frame body 200. As such, the carrying device 100 and the frame body 200 achieve detachable connection through selective engagement between the locking member 310 of the locking mechanism 300 and the lock-engaging portion 320.

Further, as shown in FIG. 5 and FIG. 6, the locking mechanism 300 may further include a driving member 330, which is switchable between a first driving position and a second driving position. As shown in FIG. 5, since the locking mechanism 300 is movably provided on the carrying device 100, it is understood that the driving member 330 and the locking member 310 are together movably provided on the carrying device 100. Specifically, the driving member 330 is movably provided on the fixing seat 120 of the carrying device 100. The driving member 330 is drivingly connected to the locking member 310. When the driving member 330 switches from the first driving position to the second driving position, the driving member 330 is adapted to drive the locking member 310 to switch from the locked position to the unlocked position. When the locking mechanism 300 is in the locked state, the driving member 330 is at the first driving position and the locking member 310 is at the locked position. When the locking mechanism 300 is in the unlocked state, the driving member 330 is at the second driving position and the locking member 310 is at the unlocked position. A moving direction of the driving member 330 and a moving direction of the locking member 310 intersect each other. Specifically, the moving direction of the driving member 330 and the moving direction of the locking member 310 are perpendicular to each other. The driving member 330 moves along a front-rear direction, while the locking member 310 moves along a left-right direction.

The carrier may further include a holding mechanism 400, which is configured to hold the locking mechanism 300 in the unlocked state. The holding mechanism 400 is movably provided on one of the carrying device 100 and the frame body 200 and is switchable among a first avoidance state, a holding state, and a second avoidance state. As shown in FIG. 11 to FIG. 14, the holding mechanism 400 is movably provided on the carrying device 100, specifically, movably provided on the fixing seat 120 of the carrying device 100.

When the carrying device 100 and the frame body 200 are connected to each other, the holding mechanism 400 is located between the locking mechanism 300 and the other one of the carrying device 100 and the frame body 200. The holding mechanism 400 is switchable between the first avoidance state and the holding state relative to both the carrying device 100 and the frame body 200. As shown in FIG. 11 to FIG. 14, when the carrying device 100 and the frame body 200 are connected to each other, the holding mechanism 400 is located between the locking mechanism 300 and the frame body 200.

When the carrying device 100 and the frame body 200 are connected to each other and the locking mechanism 300 is in the locked state, the holding mechanism 400 is not located on the moving path of the locking mechanism 300, i.e., it deviates from the moving path of the locking mechanism 300, allowing the locking mechanism 300 to move relative to the holding mechanism 400. At this time, the holding mechanism 400 is in the first avoidance state. The locking mechanism 300 can be switched from the locked state toward the unlocked state relative to the holding mechanism 400.

When the carrying device 100 and the frame body 200 are connected to each other and the locking mechanism 300 is in the unlocked state, the holding mechanism 400 is located on the moving path of the locking mechanism 300 to maintain the locking mechanism 300 in the unlocked state. At this time, the holding mechanism 400 is in the holding state. That is, when the locking mechanism 300 switches from the locked state to the unlocked state, the holding mechanism 400 also switches from the first avoidance state to the holding state. As such, it can be understood that when the holding mechanism 400 is in the holding state, the locking member 310 is maintained in the unlocked position. The user can detach the carrying device 100 from the frame body 200 without continuously performing the operation of switching the locking mechanism 300 from the locked state to the unlocked state, making it convenient to use.

When the carrying device 100 and the frame body 200 are separated from each other, i.e., when the holding mechanism 400 is no longer located between the locking mechanism 300 and the other one of the carrying device 100 and the frame body 200, the holding mechanism 400 moves toward a side away from the locking mechanism 300 and is no longer located on the moving path of the locking mechanism 300. At this time, the holding mechanism 400 is in the second avoidance state, and the locking mechanism 300 is in the locked state. That is, when the holding mechanism 400 switches from the holding state to the second avoidance state, the locking mechanism 300 also switches from the unlocked state to the locked state. As shown in FIG. 2, when the carrying device 100 and the frame body 200 are separated from each other, the holding mechanism 400 is no longer located between the locking mechanism 300 and the frame body 200.

As shown in FIG. 11 to FIG. 14, when the carrying device 100 and the frame body 200 are connected to each other, the holding mechanism 400 is located between the locking mechanism 300 and the frame body 200. Specifically, the holding mechanism 400 is located between the driving member 330 of the locking mechanism 300 and the frame body 200. When the carrying device 100 and the frame body 200 are connected to each other and the locking mechanism 300 is in the locked state, the holding mechanism 400 in the first avoidance state is not located on the moving path of the driving member 330, allowing the driving member 330 to be switched from the first driving position toward the second driving position relative to the holding mechanism 400, thereby enabling the locking member 310 to switch from the locked position toward the unlocked position, i.e., enabling the locking mechanism 300 to switch from the locked state toward the unlocked state. When the carrying device 100 and the frame body 200 are connected to each other and the locking mechanism 300 is in the unlocked state, the holding mechanism 400 in the holding state is located on the moving path of the driving member 330 to maintain the driving member 330 at the second driving position, thereby maintaining the locking member 310 at the unlocked position and maintaining the locking mechanism 300 in the unlocked state. When the carrying device 100 and the frame body 200 are separated from each other, i.e., when the holding mechanism 400 is no longer located between the frame body 200 and the driving member 330, the holding mechanism 400 is no longer located on the moving path of the driving member 330, allowing the driving member 330 to switch from the second driving position to the first driving position, the locking member 310 to switch from the unlocked position to the locked position, and the locking mechanism 300 to switch from the unlocked state to the locked state.

As shown in FIG. 10 and FIG. 13, the driving member 330 is provided with a holding recess 331. The holding mechanism 400 includes a holding member 410, which is switchable among a first avoidance position, a holding position, and a second avoidance position. Since the holding mechanism 400 is movably provided on the carrying device 100, it is understood that the holding member 410 is also movably provided on the carrying device 100. Specifically, the holding member 410 is movably provided on the fixing seat 120 of the carrying device 100. A moving direction of the holding member 410 intersects the moving direction of the driving member 330. Preferably, the moving direction of the holding member 410 and the moving direction of the driving member 330 are perpendicular to each other. An extending direction of the holding recess 331 is parallel to the moving direction of the holding member 410. When the holding mechanism 400 is in the first avoidance state, the holding member 410 is not inserted into the holding recess 331, and the holding recess 331 and the holding member 410 are offset from each other in the moving direction of the holding member 410, allowing the driving member 330 to be switched from the first driving position toward the second driving position relative to the holding member 410. The position of the holding member 410 at this time is defined as the first avoidance position of the holding member 410. When the holding mechanism 400 is in the holding state, the holding recess 331 and the holding member 410 are aligned with each other in the moving direction of the holding member 410, and at least a portion of the holding member 410 is adapted to be inserted into the holding recess 331 to restrict movement of the driving member 330 at the second driving position, thereby holding the driving member 330 at the second driving position and further holding the locking member 310 at the unlocked position. The position of the holding member 410 at this time is defined as the holding position of the holding member 410. When the holding mechanism 400 is in the second avoidance state, the holding member 410 moves out of the holding recess 331, allowing the driving member 330 to be switched from the second driving position to the first driving position relative to the holding member 410. The position of the holding member 410 at this time is defined as the second avoidance position of the holding member 410.

Specifically, as shown in FIG. 3 to FIG. 5, there are two locking mechanisms 300 respectively arranged on both sides of the carrying device 100 along the left-right direction to achieve stable mounting of the carrying device 100 on the frame body 200.

Specifically, the receiving cavity 336 penetrates the driving member 330 along the left-right direction. The driving member 330 is provided with a traction connection portion 337 located on an outer side of the third side wall 334. Specifically, the traction connection portion 337 protrudes from a side of the third side wall 334 facing away from the receiving cavity 336. The traction connection portion 337 is configured to be connected to a traction member 370 (detailed below). The driving member 330 is provided with a sleeve protrusion 338 located on an inner side of the fourth side wall 335. Specifically, the sleeve protrusion 338 protrudes from a side of the fourth side wall 335 facing the receiving cavity 336. The driving member 330 is movably mounted in the first receiving cavity 1240. Specifically, the driving member 330 may be sleeved outside the mounting cylinder 126, i.e., the mounting cylinder 126 is located in the receiving cavity 336 of the driving member 330. The sleeve protrusion 338 protrudes from the fourth side wall 335 toward the mounting cylinder 126, and the traction connection portion 337 is closer to the connecting cylinder 1241 relative to the sleeve protrusion 338. The driving member 330 may move in the first receiving cavity 1240 substantially along the front-rear direction.

Referring to FIG. 5, FIG. 11, and FIG. 12 together, the mounting cylinder 126 extends beyond the first connecting wall 1221 and protrudes from an outer side of the first connecting wall 1221, i.e., the mounting cylinder 126 protrudes from a side of the first connecting wall 1221 facing away from the second connecting wall 1222. In this embodiment, the locking member 310 is a locking pin, and the locking member 310 has a locking end 311. Specifically, the locking end 311 is exposed at the location of the engagement protrusion 1211. The lock-engaging portion 320 is a locking groove provided on the frame body 200 that is capable of being engaged with the locking pin. Specifically, the locking groove is located in the engagement recess 221. As shown in FIG. 11 and FIG. 12, when the locking member 310 is in the locked position, at least the locking end 311 of the locking member 310 is capable of extending out of the hollow inner cavity 1261 of the mounting cylinder 126 and extending into the locking groove on the frame body 200 to be engaged with the lock-engaging portion 320. As shown in FIG. 13 and FIG. 14, when the locking member 310 is in the unlocked position, the locking end 311 of the locking member 310 retracts into the hollow inner cavity 1261 of the mounting cylinder 126 and separates from the locking groove on the frame body 200 to be disengaged from the lock-engaging portion 320. The locking end 311 has an inclined locking surface 3111. The locking surface 3111 is located on a lower side of the locking end 311 and may gradually incline upward along a direction toward its tip, for example.

Further, as shown in FIG. 9 and FIG. 10, the locking mechanism 300 further includes a driving pin 341. The driving member 330 has a driving inclined groove 339. The locking member 310 is fixedly connected to the driving pin 341 (see FIG. 12 and FIG. 14). The driving pin 341 is inserted into the driving inclined groove 339 and is capable of sliding along the driving inclined groove 339. An extending direction of the driving inclined groove 339 intersects both the moving direction of the driving member 330 and the moving direction of the locking member 310, such that when the driving member 330 moves, the driving member 330 is capable of driving the locking member 310, whose moving direction intersects the moving direction of the driving member 330, to move. Specifically, the first side wall 332 and the second side wall 333 of the driving member 330 are provided with driving inclined grooves 339 arranged opposite to each other. The driving inclined grooves 339 gradually approach the traction connection portion 337 along a direction toward the first connecting wall 1221. The driving pin 341 passes through the locking member 310 substantially along the up-down direction and is fixedly connected to the locking member 310. Both ends of the driving pin 341 respectively protrude from an upper surface and a lower end surface of the locking member 310 and are respectively inserted into the two driving inclined grooves 339 of the driving member 330 via the two elongated slots 1260 of the mounting cylinder 126. As such, the driving member 330 is capable of driving, via its movement along the front-rear direction, the locking member 310 to move along the left-right direction. The driving member 330 drives, via its movement between the first driving position and the second driving position, the locking member 310 to move between the locked position and the unlocked position.

Further, as shown in FIG. 11 to FIG. 14, the fixing seat 120 is provided with a second mounting portion for the holding mechanism 400 to move. The second mounting portion is provided on the first connecting wall 1221. The second mounting portion encloses to form a second receiving cavity 127. The second mounting portion is provided with a first communication hole 1281 through which the holding mechanism 400 (specifically the holding member 410) protrudes out of the second receiving cavity 127 to restrict movement of the driving member 330. The first communication hole 1281 is in communication with the first receiving cavity 1240 receiving the driving member 330. Relative to the holding member 410 in the first avoidance position of holding member 410, a portion of the holding member 410 in the holding position extending out of the second receiving cavity 127 through the first communication hole 1281 is longer. The second mounting portion is located substantially above the mounting cylinder 126. Specifically, refers to FIG. 8 together. The second mounting portion further includes a fixing member 450. The fixing member 450 is fixed to a side of the second receiving cavity 127 close to the first receiving cavity 1240 by a fastening member 460. The fixing member 450 is provided with the aforementioned first communication hole 1281. The second mounting portion is further provided with a second communication hole 1282 through which the holding mechanism 400 protrudes out of the second receiving cavity 127 to switch to the second avoidance state. The second mounting portion is in communication with the outside of the fixing seat 120 via the second communication hole 1282. Relative to the holding mechanism 400 in the first avoidance state or in the holding state, a portion of the holding mechanism 400 in the second avoidance state extending out of the second receiving cavity 127 through the second communication hole 1282 is longer.

Further, as shown in FIG. 9 to FIG. 11, the holding recess 331 is provided on a side of the first side wall 332 facing the holding member 410. The first side wall 332 faces the first communication hole 1281. The holding recess 331 is provided on a side of the first side wall 332 facing the first communication hole 1281 and is formed by recessing from a surface of the first side wall 332 facing the first communication hole 1281 toward a surface of the first side wall 332 away from the first communication hole 1281. The holding mechanism 400 may further include a first reset member 431. The first reset member 431 is adapted to exert a force on the holding member 410 to enable the holding member 410 to move toward the locking mechanism 300 (specifically the driving member 330) and abut against the locking mechanism 300 (specifically the driving member 330). As such, when the carrying device 100 and the frame body 200 are connected to each other, the holding member 410, under the elastic force of the first reset member 431, is capable of switching from the first avoidance position to the holding position. Specifically, when the carrying device 100 and the frame body 200 are connected to each other and the holding member 410 is in the first avoidance position, the holding member 410, under the elastic force of the first reset member 431, is capable of abutting against a surface of the first side wall 332 facing the first communication hole 1281 to maintain the holding member 410 in the first avoidance position. When the carrying device 100 and the frame body 200 are connected to each other and the holding member 410 is in the holding position, the driving member 330 moves such that its holding recess 331 is opposite to the first communication hole 1281 or opposite to the holding member 410. The holding member 410, which has lost the pushing force from the first side wall 332, moves to the holding position under the elastic restoring force of the first reset member 431, thereby being inserted into the holding recess 331 and abutting against a surface of the holding recess 331 facing the first communication hole 1281 or facing the holding member 410. When the carrying device 100 and the frame body 200 are separated from each other, the holding member 410, under the elastic force of the first reset member 431, may also abut against the surface of the first side wall 332 facing the first communication hole 1281.

When the holding seat 420 is at the first position, the holding member 410 is switchable between the holding position and the first avoidance position. When the holding seat 420 is at the second position, the holding member 410 moves to the second avoidance position. The holding seat 420 is drivingly connected to the holding member 410. Specifically, the holding member 410 is slidably connected to the holding seat 420. The holding mechanism 400 may further include a second reset member 432. The second reset member 432 is adapted to exert a force on the holding seat 420 to enable the holding seat 420 to move toward a side away from the driving member 330, enabling the holding seat 420 to drive the holding member 410 to move to the second avoidance position. When the carrying device 100 and the frame body 200 are connected to each other, the holding seat 420, under the force of the second reset member 432, is adapted to be pushed by the frame body 200 to be maintained at the first position. When the carrying device 100 and the frame body 200 are separated from each other, the holding seat 420, under the force of the second reset member 432, is adapted to protrude outward from the fixing seat 120 through the second communication hole 1282.

Specifically, as shown in FIG. 9 to FIG. 11, the holding seat 420 is movably provided in the second mounting portion. The holding seat 420 has an insertion groove 421. At least a portion of the holding member 410 is inserted into the insertion groove 421. The holding mechanism 400 further includes a guide pin 440. The guide pin 440 is connected to the holding member 410. Specifically, the guide pin 440 passes through the holding member 410 substantially along a direction perpendicular to the extending direction of the holding member 410 and is fixedly connected to the holding member 410. Opposite side walls of the holding seat 420 have guide holes 422. Both guide holes 422 are in communication with the insertion groove 421, and both guide holes 422 are elongated holes extending along the extending direction of the holding seat 420.

The second reset member 432 is located between the carrying device 100 and the holding seat 420. The second reset member 432 may be a spring. An outer side wall of the holding seat 420 may be provided with a first limiting protrusion 423. The second reset member 432 is sleeved on the holding seat 420, and both ends of the second reset member 432 respectively abut against the fixing member 450 and the first limiting protrusion 423. As such, the second reset member 432 is adapted to exert a force on the holding seat 420 to enable the holding seat 420 to move in a direction away from the fixing member 450, i.e., move toward the second position. The holding seat 420 is movably provided in the second mounting portion, and at least a portion of the holding seat 420 is capable of protruding through the second communication hole 1282 to be pushed by the other one of the carrying device 100 and the frame body 200. The second mounting portion is further provided with a second limiting protrusion 1212. The second limiting protrusion is formed at an edge of the second communication hole 1282. The first limiting protrusion 423 is adapted to abut against the second limiting protrusion 1212 to define the second position of the holding seat 420. In other embodiments, only the first reset member 431 may be provided. The first reset member 431 may not only drive the holding member 410 to move toward the holding position but also drive the holding seat 420 to move toward the second position.

The first end 3821 is located behind the second end 3822, i.e., the first end 3821 is farther from the first traction end 371 than the second end 3822. As shown in FIG. 16 and FIG. 18, the end of the traction member 370 away from the first traction end 371 forms a second traction end 372. The second traction end 372 extends downward to the fixing seat 120, enters the first receiving cavity 1240 through the connecting hole 1241a of the connecting cylinder 1241, and is connected to the traction connection portion 337 of the driving member 330. When the operating member 360 is not pressed, the linkage pin 342 is located at the first end 3621 of the first linkage groove 362 and the first end 3821 of the second linkage groove 382. When the operating member 360 is pressed downward, the operating member 360 pushes against the second driving inclined surface 381 via the first driving inclined surface 361, enabling the linkage member 380 to move rearward. Meanwhile, the linkage pin 342 moves to the second end 3622 of the first linkage groove 362 and the second end 3822 of the second linkage groove 382. The linkage member 380 moves rearward and drives the driving member 330 forward via the traction member 370, enabling the driving member 330 to move from the first driving position to the second driving position. Simultaneously, the driving member 330 drives the locking member 310 to move from the locked position to the unlocked position, thereby unlocking the locking mechanism 300 and allowing the carrying device 100 to be detached from the frame body 200.

Below, the detachment process of the carrying device 100 and the frame body 200 is described in detail using the structure on one side of the carrier as an example.

As shown in FIG. 15, first, press the operating member 360 downward, i.e., along direction D1. The operating member 360 moves along direction D1 and simultaneously pushes against the second driving inclined surface 381 via the first driving inclined surface 361 to drive the linkage member 380 to move rearward, i.e., along direction D2. The linkage pin 342 moves from the first end 3621 to the second end 3622 along the first linkage groove 362 and from the first end 3821 to the second end 3822 along the second linkage groove 382. While moving along direction D2, the linkage member 380 drives the first traction end 371 to move in direction D2 and, drives the second traction end 372 via the first traction member 370 to move forward, i.e., in the opposite direction of direction D2. Consequently, the second traction end 372 also drives the driving member 330 to move from the first driving position to the second driving position in the opposite direction of direction D2. At this time, the third reset member 350 is compressed and deformed. When the driving member 330 moves in the opposite direction of direction D2, the driving member 330 drives the locking member 310 to move from the locked position to the unlocked position through the engagement of the driving inclined groove 339 and the driving pin 341, disengaging the locking member 310 from the lock-engaging portion 320, i.e., switching from the state shown in FIG. 11 and FIG. 12 to the state shown in FIG. 13 and FIG. 14. When the locking member 310 moves to the unlocked position, the holding recess 331 of the driving member 330 is just aligned with the first communication hole 1281, i.e., aligned with the holding member 410. The holding member 410, which has lost the pushing force from the first side wall 332, moves from the first avoidance position to the holding position under the elastic restoring force from the first reset member 431, thereby being inserted into the holding recess 331. This restricts movement of the driving member 330, and the locking member 310 is maintained in the unlocked position. At this time, the external force applied to the operating member 360 can be removed, i.e., the operating member 360 is no longer pressed, and the locking member 310 is still maintained in the unlocked position. The user can then directly lift upward, i.e., pull along the opposite direction of direction D1, the handle 130 or other parts of the carrying device 100, enabling the fixing seat 120 to gradually pull out of the engagement seat 220 along the opposite direction of direction D1. During the process of the fixing seat 120 pulling out of the engagement seat 220, the holding seat 420 changes from abutting against the pushing portion 2221 to abutting against the inclined portion 2222. Since the inclined portion 2222 gradually inclines away from the second communication hole 1282 from the first side 2222b toward the second side 2222c, the holding seat 420 gradually returns to the second position as the fixing seat 120 is pulled away. When the fixing seat 120 is completely disengaged from the engagement seat 220, the holding seat 420, which has lost the pushing action of the pushing protrusion 222, moves to the second position under the elastic restoring force of the second reset member 432. During the process of the holding seat 420 moving to the second position, the holding seat 420 drives the holding member 410 to move from the holding position to the second avoidance position, i.e., the holding member 410 exits from the holding recess 331. After losing the restricting effect of the holding member 410, the driving member 330 moves to move back to its original position along direction D2 under the elastic force of the third reset member 350 and simultaneously drives the locking member 310 to move from the unlocked position to the locked position through the engagement of the driving inclined groove 339 and the driving pin 341. Simultaneously, the driving member 330 drives the linkage member 380 and the operating member 360 to move back to its original position via the traction member 370.

The carrier presented by the present disclosure has at least the following technical effects:

One of the carrying device 100 and the frame body 200 is provided with the locking mechanism 300 and the holding mechanism 400. The locking mechanism 300 is switchable between the locked state and the unlocked state to control the locking and separation of the carrying device 100 and the frame body 200. The holding mechanism 400 is switchable between the first avoidance state and the holding state. When the carrying device 100 and the frame body 200 are connected to each other and the locking mechanism 300 is in the locked state, the holding mechanism 400 deviates from the moving path of the locking mechanism 300, allowing the locking mechanism 300 to move relative to the holding mechanism 400. At this time, the holding mechanism 400 is in the first avoidance state, and the locking mechanism 300 is capable of switching from the locked state to the unlocked state. When the carrying device 100 and the frame body 200 are connected to each other and the locking mechanism 300 is in the unlocked state, the holding mechanism 400 is located on the moving path of the locking mechanism 300, and the holding mechanism 400 is in the holding state, the locking mechanism 300 is maintained in the unlocked state. As such, when it is necessary to detach the carrying device 100 from the frame body 200, after the user unlocks the locking mechanism 300, the holding mechanism 400 is capable of maintaining the locking mechanism 300 in the unlocked state, allowing the user to remove the carrying device 100 from the frame body 200 without continuously performing the unlocking operation, which is convenient to use.

The technical features of the above embodiments can be combined arbitrarily. For brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered as within the scope recorded in this specification.

The above embodiments only represent several implementations of the present application, and the description thereof is relatively specific and detailed, but should not be construed as limiting the scope of the patent application. It should be noted that, for those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all fall within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
