Referring to FIG. 1 and FIG. 2, an embodiment of the present disclosure provides a backpack supporting bar 100, which is used in a backpack used in outdoor hiking or mountaineering. Carrying a backpack for a long time brings a great burden to a user, so that the backpack supporting bar 100 can be used to support the back of the user to reduce the burden.

The backpack supporting bar 100 includes at least two sections of supporting sub-bars 10 connected to each other in sequence; the supporting sub-bars 10 include a first supporting sub-bar 11 and a second supporting sub-bar 12; end portions of the first supporting sub-bar 11 and the second supporting sub-bar 12 are movably connected to each other; and the backpack supporting bar 100 has a first state where the entire backpack supporting bar extends for supporting and a second state where adjacent supporting sub-bars are folded to each other.

The supporting sub-bars 10 may form a two-section folding structure, a three-section folding structure, a four-section folding structure, or the like.

Further, the backpack supporting bar 100 includes a first supporting sub-bar 11 and a second supporting sub-bar 12 connected to the first supporting sub-bar; in the first state, the backpack supporting bar 10 is roughly S-shaped; the first supporting sub-bar 11 bends in a first direction to form a first supporting arc; and the second supporting sub-bar 12 bends in a second direction opposite to the first direction to form a second supporting arc. In this embodiment, by the use of the two-section connected structure, the supporting arcs that bend in the opposite directions respectively are configured to adaptively support the upper part and the lower part of the back of a user.

Further, the backpack supporting bar 10 is roughly flat, and the first direction and the second direction are perpendicular to a flat surface of the backpack supporting bar, respectively. In this embodiment, the backpack supporting bar 10 is flat, which further supports and adapts to the back of a user. This enlarges a supporting area and reduces an occupied space.

Further, the backpack supporting bar 10 further includes two protective end sleeves 13; adjacent end portions of the first supporting sub-bar 11 and the second supporting sub-bar 12 are rotatably connected; and the two protective end sleeves 13 are respectively arranged at end portions, facing away from each other, of the first supporting sub-bar 11 and the second supporting sub-bar 12. In this embodiment, the protective end sleeves 13 are used to protect the end portions of the backpack supporting bar 10, so that during mounting and removal of the backpack supporting bar 10, the end portions of the backpack supporting bar 10 are avoided from hurting or damaging a user and a backpack.

Furthers, the first supporting sub-bar 11 and the second supporting sub-bar 12 are connected by a rivet 14. In this embodiment, the rotatable connection is achieved through the rivet 14, so that the connected structure is more stable, and the space occupied by the connected structure is also relatively reduced.

Further, the backpack supporting bar 10 is made of an aluminum material. In other embodiments, the aluminum material may also be replaced with an iron bar. However, compared with the iron bar, an aluminum bar has more stable structural performance, may not be rusted and damaged, has a smaller weight, may not add an additional burden on the backpack, and has a good advantage.

An embodiment of the present disclosure further provides a backpack 200. The backpack 200 includes a supporting back vest 201 and two backpack supporting bars 100 described above, wherein the two backpack supporting bars 100 are detachably adapted and connected to the supporting back vest 201.

In an embodiment, the backpack supporting bars 100 may be arranged on an outer side of the supporting back vest 201, as shown in FIG. 3 and FIG. 4.

In another implementation, further, an outer side of the supporting back vest 201 is connected with straps 202; a strip-shaped accommodating bag (not shown) is arranged on an inner side of the supporting back vest 201; and the backpack supporting bars 100 are accommodated in the strip-shaped accommodating bag to form a supporting structure for the supporting back vest 201. When the backpack is used, the backpack supporting bars are in contact and cooperates with the back of a user. In this embodiment, by the arrangement of the strip-shaped accommodating bag, the backpack supporting bars 100 are limited. The backpack supporting bars 100 are arranged on the inner side of the supporting back vest 201. To remove the backpack supporting bars 100, the backpack supporting bars 100 are removed from the inner side of the backpack 200 and are folded, so that the removal operation can be completed without occupying a large removal space. Furthermore, the folded portion of the backpack supporting bar 10 can be stored in the backpack 200, without causing the problem of additional space occupation.

Further, the backpack 200 further includes a backpack surface (not shown) covering the supporting back vest 201; the backpack surface and the supporting back vest 201 are enclosed to form a backpack accommodating space (not shown); the backpack accommodating space is provided with an opening in a top; the strip-shaped accommodating bag is configured to extend downwards from the opening to a bottom close to the backpack accommodating space; and the strip-shaped accommodating bag is provided with an open hole close to the opening. In this embodiment, a lower end of the strip-shaped accommodating bag is closed, and an upper end is opened. This facilitates the mounting of the backpack supporting bar 10 and maintaining of a supporting limiting state.

Further, the supporting back vest 201 is provided with a bag cover (not shown) that is able to cover the open hole. In this embodiment, by the arrangement of the bag cover, the backpack supporting bar 10 is maintained in the supporting limiting state.

Specifically, the bag cover covers the open hole through a button or a hook and loop fastener.

In other embodiments, polyethylene (PE) boards may be further arranged in the supporting back vest 201. By the opposite arrangement of the upper and lower PE boards, when the backpack is used, the two PE boards are roughly integrated to support the backpack. When folding is required, the backpack is folded by a gap between the two PE boards. This can further improve the comfort of carrying the backpack. It can be understood that due to the adding of a material and the processing complexity, the above structure can also be omitted.

According to the backpack supporting bar and the backpack of the present disclosure, the supporting bar is set to be a folding structure including at least two sections. In the processes of mounting the backpack supporting bar to the backpack and removing the backpack supporting bar from the backpack, the operation convenience is improved. During use, a good supporting effect can be maintained. After the use, the storage volume can be effectively reduced, so that the experience of a backpack user is greatly improved; and the logistics can also be saved, to facilitate the transportation; and the transportation cost of the backpack can be reduced, thereby saving the purchase cost of a user. In addition, the backpack supporting bar and the backpack are simple in structure and are applicable to large-scale industrial production.

In addition, the two-section folding structure is also better than other types of structures. For example, the supporting bar is set to be a telescopic rod structure. The supporting bar extends and retracts by extending and retraction actions. However, the telescopic structure is relatively complex compared with the riveted folded structure, increasing the overall material and manufacturing costs.
