Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0024] Combine the following Figures 1 to 3 The invention describes a wheelchair shock absorbing mechanism.

[0025] like Figures 1 to 3 As shown, the utility model provides a wheelchair shock absorbing mechanism, including a wheelchair frame, a movable wheel, a shock absorber, a wheel axle and a connecting seat, one end of the connecting seat is rotatably connected to the wheelchair frame, the other end of the connecting seat is rotatably connected to the lower end of the shock absorber, the upper end of the shock absorber is rotatably connected to the wheelchair frame, one end of the wheel axle is connected to the connecting seat, the other end of the wheel axle is rotatably connected to the movable wheel, and the connection between the wheel axle and the connecting seat is located between the shock absorber and the wheelchair frame.

[0026] In the wheelchair shock absorption mechanism and wheelchair provided in this embodiment, the shock absorber can play a basic shock absorption function and provide the user with a comfortable use experience, and a triangular structure is formed between the wheelchair frame, the shock absorber and the connecting seat. The wheel axle connected to the movable wheel is connected to the middle position of the connecting seat, which can be understood as being connected to the middle of the bottom edge of the triangle. The force is more uniform. When the wheelchair bumps up and down, the triangular structure can provide better support for the wheelchair, avoid the overall tilt of the wheelchair, and have better stability and better safety performance.

[0027] In some embodiments, the wheelchair shock absorbing mechanism further comprises a connecting shaft and a connecting nut. A connecting hole is provided on a side of the wheelchair frame away from the wheel axle. The connecting shaft is rotatably connected to the connecting hole. The connecting seat is connected to the connecting shaft. The connecting nut is threadedly connected to the connecting shaft. Specifically, Figure 1 As shown, the connecting hole is located on the right side of the wheelchair frame, and the connecting shaft is located on the right side of the connecting seat. The wheelchair frame can be inserted into the connecting seat to reduce the occupied space and make the overall structure more compact.

[0028] In some embodiments, the wheelchair shock absorbing mechanism also includes a shock absorbing seat, which is arranged on the wheelchair frame, and the shock absorbing seat is located above the connecting seat. The upper end of the shock absorber is rotatably connected to the shock absorbing seat to facilitate the connection of the shock absorber.

[0029] In some embodiments, the lower end of the shock absorber is connected to the connecting seat by screws and nuts to facilitate disassembly and replacement.

[0030] In some embodiments, a through hole is provided in the middle of the connecting seat, and the through hole passes through the connecting seat in a vertical direction, thereby reducing the weight and making the wheelchair lighter.

[0031] In some embodiments, the wheelchair frame includes a wheelchair longitudinal rod, and the shock absorber and the connecting seat are both connected to the wheelchair longitudinal rod. The connecting seat can be rotated relative to the wheelchair longitudinal rod. When the shock absorber is in a normal state, the shock absorber and the wheelchair longitudinal rod are both in an inclined state, which can form a stable triangular structure, making the entire wheelchair more stable.

[0032] The utility model also provides a wheelchair, comprising the above-mentioned wheelchair shock absorbing mechanism, which has a certain shock absorbing effect and a more stable structure.

[0033] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
