CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202222507272.3, filed on Sep. 21, 2022, the entire contents of which are hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to the field of exercise machines, and in particular, relates to an exercise bench.

BACKGROUND

With the development of science and technology and the enhancement of people's sports consciousness, more and more people take exercise and fitness as a part of life, and exercise training machines have gradually become family-oriented and portable. In the related art, the applicant has carried out a great deal of research on the contents related to portable exercise apparatuses, and has proposed a related solution of a portable exercise bench based on a resistance pull cable, in which a motor supplies a resistance force to the pull cable, and a user grips the pull cable to perform exercises. With further research on products, it is found that the conventional exercise benches have a lower cable escape position. When performing exercises on such an exercise bench, a user may only perform exercises in a vertical direction for his or her upper arms due to restriction of a cable escape direction of the exercise bench. Therefore, the products need to be developed, such that user's more and more flexible exercise needs are accommodated.

SUMMARY

Various embodiments of the present disclosure provide an exercise bench. The exercise bench includes a machine body, a deck arranged at a bottom of the machine body, a shield arranged on each of two sides of the deck, two pull cables, and resistance assemblies configured to supply resistance forces to the two pull cables, the resistance assemblies being disposed inside the machine body, the two pull cables being respectively led out from the shields on the two sides of the deck, wherein the shields on the two sides of the deck are movably connected to the deck, each of the shields on the two sides of the deck are provided with a recess configured to receive a pull cable steering mechanism, the pull cable steering mechanisms being configured to guide the two pull cables.

The resistance assembly arranged in the machine body supplies resistance forces to the pull cables; the shields on the two sides of the deck are movably connected to the deck; in the case that the shields are expanded, the two pull cables are respectively led out from the shields on the two sides of the deck; and in the case that the pull cable steering mechanisms are mounted on the recess, the two pull cables change directions by virtue of the pull cable steering mechanisms, such that the force apply direction is no longer limited to the vertical direction when the user uses the exercise bench to perform exercises, which solves the problem of a single training mode in the related art.

In some embodiments, in order to enable a user to perform exercises in any posture and to meet different exercise requirements of the user, a sit board is arranged at a top portion of the machine body, wherein the sit board is movably connected to the top portion of the machine body, such that the sit board is capable of overlaying the top portion of the machine body or expanding towards an extension direction of the deck.

In some embodiments, since the user can apply a force in a horizontal direction to perform exercises after the pull cables are guided by the pull cable steering mechanisms, and when performing exercises in the horizontal direction, the user may provide the first support and the support with a component force in the horizontal direction such that the first support and the second support approach to each other. In order to avoid deformation of the first support and/or the second support caused by the component force in the horizontal direction, top portions of the first support and the second support are connected to form an integral structure.

In some embodiments, in order to accommodate different training height requirements of a user in a standing posture and a sitting posture, the first winding structure is provided with a first locking member, and the first winding structure is slidably connected to the first support and a position of the first winding structure relative to the first support is fixed via the first locking member; the second winding structure is provided with a second locking member, and the second winding structure is slidably connected to the second support and a position of the second winding structure relative to the second support is fixed via the second locking member.

In summary, one or more technical solutions according to the present disclosure solve the problem in the related art that the user's exercise mode is limited by the cable escape direction of the exercise bench, and the user may only apply the force in the vertical direction to perform exercises. The exercise bench according to the present disclosure eliminates the limitation of the use of the conventional exercise bench, and has good applicability.

Specifically, when a user performs exercises on an exercise bench according to the present disclosure, the shields 3 on the two sides of the deck 2 are firstly expanded, and then the pull cables led out from the shields 3 are pulled, and exercises are performed based on the resistance forces supplied by the resistance assembly to the pull cables. The user may cause the sit board 4 to overlay the top portion of the machine body 1, or expand the sit board 4 towards the extension direction of the deck 2 to perform exercises according to actual needs, adjust the positions of the first winding structure and/or the second winding structure according to his/her height or exercise posture, and adjust the lengths of the first support 9 and/or the second support 10 to perform personalized exercises.

An exemplary embodiment of the present disclosure provides an exercise bench. Referring to FIG. 5, based on the above embodiments, the resistance assembly includes a first motor 11, a first winding wheel 13, a second motor 12, and a second winding wheel 14, wherein the first motor 11 and the second motor 13 are respectively configured to control the first winding wheel 13 and the second winding wheel 14.

The first motor 11 and the second motor 12 operate independently to respectively supply resistance forces to the pull cables. The first motor 11 is one or a group of motors, the second motor 12 is one or a group of motors, and both the first motor 11 and the second motor 12 may be DC motors, asynchronous motors, or synchronous motors, which are not limited in this embodiment. In the case that a user pulls two pull cables while doing exercises, a rotor of the first motor 11 and/or the second motor 12 passively rotates to supply the resistance force in a direction opposite to a pulling direction of the user for the corresponding winding wheel, and the first motor 11 and the second motor 12 independently supply a same or different resistance forces to the two pull cables, such that the user's different exercise needs are flexibly satisfied.

In this embodiment, the resistance assembly further includes a first cable escape mechanism 15 and a second cable escape mechanism 16, wherein the first cable escape mechanism 15 and the second cable escape mechanism 16 are respectively arranged at movable connection pivots between the corresponding shields 3 and the deck 2, and the two pull cables are respectively led from the corresponding winding wheels into the corresponding cable escape mechanisms and are subsequently led out from the corresponding shields 3.

The first steering wheel is arranged in the housing, and the housing is arranged at movable connection pivots between the shields 3 and the deck 2. A pull cable wound around the first winding wheel is led out from the shields 3 after changing a direction at a first time via the first steering wheel and changing the direction at a second time via the second steering wheel. Since the portion from the first winding wheel to the first steering wheel of the pull cable is coaxial with the movable connection pivots between the shield 3 and the deck 2, the friction generated by the pull cable contacting with other parts of the device when the user rotates the position of the shield 3 is prevented. After being led out from the first winding wheel, the pull cable is directly led out from the shield 3 via the second winding wheel and for changing the direction, and the structure is simple. The second cable escape mechanism 16 has the same structure as the first cable escape mechanism 15, and the first cable escape mechanism 15 differs from the second cable escape mechanism 16 only in that these two shields 3 respectively correspond to the two sides of the deck 2. Therefore, the description of the second cable escape mechanism 16 in this embodiment is not repeated herein.
