[0023] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0024] To better understand the above technical solution, exemplary embodiments of the present utility model will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present utility model are shown in the accompanying drawings, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present utility model and to fully convey the scope of the present utility model to those skilled in the art.

[0025] To better understand the above technical solution, the above technical solution will be described in detail below in combination with the accompanying drawings of the specification and specific implementation manners.

[0026] Below, reference is made to Figures 1-4 to describe in detail the implementation of the wheelchair shock-absorbing footrest proposed according to the embodiments of the present utility model.

[0027] The wheelchair shock-absorbing footrest according to the embodiment of the present utility model includes: a bracket 1 and a footrest 2.

[0028] Specifically, the bracket 1 has a first limiting portion 11; the footrest 2 has a second limiting portion 21, and the footrest 2 is swingably connected to the bracket 1 so that the footrest 2 can swing and switch between a storage state and a use state. In the use state, the second limiting portion 21 elastically abuts against the first limiting portion 11 so that the footrest 2 elastically supports the user's feet. In the storage state, the second limiting portion 21 disengages from abutting against the first limiting portion 11.

[0029] That is to say, the footrest 2 is swingably connected to the bracket 1, so that the footrest 2 can swing with the connection point between the footrest 2 and the bracket 1 as the fulcrum, thereby facilitating the conversion of the footrest 2 between the use state and the storage state. In the use state, the second limiting portion 21 of the footrest 2 elastically contacts the first limiting portion 11, so that the footrest 2 is restricted to elastically swing within the elastic deformation range, facilitating the elastic support of the user's feet, playing a shock-absorbing role, thereby improving the comfort of use. By swinging the footrest 2, the second limiting portion 21 is disengaged from abutting against the first limiting portion 11, facilitating the switching of the footrest 2 from the use state to the storage state and facilitating the storage of the footrest 2, reducing the occupied space.

[0030] Thus, by the swing connection between the foot pedal 2 and the bracket 1, the foot pedal 2 can be switched between the use state and the storage state. In the use state, through the elastic contact between the first limiting part 11 of the bracket 1 and the second limiting part 21 of the foot pedal 2, the user's foot placed on the foot pedal 2 has an elastic supporting effect, thereby improving comfort. In the storage state, by swinging the foot pedal 2, the second limiting part 21 and the first limiting part 11 are disengaged from abutting, which facilitates the storage of the foot pedal 2. The wheelchair shock-absorbing foot structure is simple, can elastically support the feet, improve comfort, and is convenient for storage.

[0031] For the bracket 1 and the foot pedal 2, the bracket 1 has a horizontal section 12, and a first connecting part 13 extends along the radial direction of the horizontal section 12. The foot pedal 2 has an extension section 22, and a second connecting part 23 extends along the radial direction of the extension section 22. The second connecting part 23 is hinged to the first connecting part 13. It can be understood that by setting the extension section 22 of the foot pedal 2, it is convenient to place the foot pedal 2 in a set position for the user's foot to be placed on the foot pedal 2. Through the hinge connection between the first connecting part 13 and the second connecting part 23, it is convenient for the foot pedal 2 to swing, thereby facilitating the switching of the foot pedal 2 between the storage state and the use state. Among them, the bracket 1 can be the front frame of the wheelchair, which includes a horizontal section 12 and a vertical section 14, and a wheel 4 is installed on the vertical section 14.

[0032] For the first connecting part 13 and the second connecting part 23, the second connecting part 23 is arranged at the middle position of the extension section. The first connecting part 13 and the horizontal section 12 jointly construct a U-shaped swinging space for the extension section 22 to swing. The first limiting part 11 is arranged on the horizontal section 12 within the U-shaped swinging space, and the second limiting part 21 is arranged at the end of the extension section 22. It can be understood that through the U-shaped swinging space formed by the first connecting part 13 and the horizontal section 12, it is convenient for the extension section 22 to make way when the foot pedal 2 swings, thereby facilitating the conversion of the foot pedal 2 between the storage state and the use state; by arranging the first limiting part 11 on the horizontal section 12 within the U-shaped swinging space and the second limiting part 21 at the end of the extension section 22, the distance between the position where the foot of the foot pedal 2 is placed and the position of the cooperation between the first limiting part 11 and the second limiting part 21 is increased, plus the elastic deformation of the foot pedal 2 itself, so that the elastic buffering effect of the foot pedal 2 on the foot is better. Among them, the second connecting part 23 can be arranged at the middle position of the extension section 22, which is convenient for reducing the swinging radius of the foot pedal 2, thereby reducing the occupied space of the foot pedal 2. The first connecting part 13 can be integrally formed on the bracket 1. The second connecting part 23 can be a hollow cylindrical shape with two convex sides, and then a rotating shaft is passed through the hollow part of the cylinder to cooperate with the first connecting part 13, and finally fixed with screws passing through the holes on the first connecting part 13 and connected to the rotating shaft.

[0033] For the elastic abutment between the first limiting part 11 and the second limiting part 21, an elastic member 3 is provided on the first limiting part 11 or / and the second limiting part 21. Understandably, by providing the elastic member 3 on the first limiting part 11 or / and the second limiting part 21, it is convenient for the elastic contact between the first limiting part 11 and the second limiting part 21, thereby facilitating the elastic support of the footrest 2 for the foot. Among them, the elastic member 3 can be an elastic material such as rubber or silica gel.

[0034] Regarding the installation position of the elastic member 3, the second limiting part 21 is provided with an installation groove 24, and the elastic member 3 is arranged in the installation groove 24. Understandably, by arranging the elastic member 3 in the installation groove 24 of the second limiting part 21, the elastic member 3 can be limited in the installation groove 24, preventing displacement when contacting the first limiting part 11. It also facilitates the quick installation of the elastic member 3 in place, saving the material of the elastic member 3 and reducing costs while realizing the function of elastically supporting the foot. Among them, the elastic member 3 can be pasted in the installation groove 24, or there can be a clamping hole in the installation groove 24, and the elastic member 3 is provided with a protrusion that can be clamped with the clamping hole.

[0035] Regarding the elastic clip, the elastic member 3 is silica gel. Understandably, the silica gel material has good elastic deformation function, and at the same time has the advantages of durability and environmental protection, avoiding adverse effects on the health of users.

[0036] Regarding the position of the first connecting member 13, the first connecting member 13 is located at the middle position of the horizontal section 12, and the first connecting member 13 is inclined downward and forward. Understandably, by the first connecting member 13 being located at the middle position of the horizontal section 12, it is convenient to leave space on both sides of the first connecting member 13, so that the user has a larger placement space and improves the comfort of use. By the first connecting member 13 being inclined downward and forward, it is convenient to match the footrest 2 which is inclined downward and forward from the connection of the bracket 1, so that when the footrest 2 is in use, the overlapping degree of the extension section 22 and the first connecting member 13 is better and more beautiful.

[0037] Regarding the footrest 2, the extension section 22 and the second connecting member 23 are integrally formed on the footrest 2. Understandably, the existing footrest 2 is usually connected to the bracket 1 by two connecting rods, or two footrests 2 are respectively connected to the bracket 1 by connecting rods. By the extension section 22 and the second connecting member 23 being integrally formed on the footrest 2, the integrity of the footrest 2 is better, and at the same time, the installation difficulty of the footrest 2 can be reduced. Among them, the whole footrest 2 can be in the shape of a spatula, and the position on the footrest 2 for placing the foot can be covered with a rubber layer to increase the friction between the foot and the footrest 2.
