The seat support tube 1 includes a first support part 11 and a second support part 12. The first support part 11 is horizontally arranged, and the second support part 12 is inclined downward.

[0028] For ease of explanation, in this embodiment, each orientation is as follows: Figure 1 As shown.

[0029] Specifically, the two side supports 3 are located on the left and right sides of the connecting frame 2, respectively. The two side supports 3 are connected through the connecting frame 2. The two seat support tubes 1 are both connected to the connecting frame 2 and located on the upper side of the connecting frame 2. The seat support tube 1 includes a first support part 11 and a second support part 12. The first support part 11 is set horizontally, and the second support part 12 is set downward. The seat is supported by the seat support tube 1 and can fit against the seat support tube 1. It can be understood that when the user sits on the seat, he / she does not sit flat on the seat, but will have a tendency to lean backward. For some users with leg injuries, when bandaging the legs, when raising the legs for medical staff to bandage, the inclined seat can ensure that the user's buttocks and thighs can contact the seat. The contact area is large, and the overall center of gravity is still located in the middle or slightly backward, which greatly reduces the risk of slipping and avoids certain safety hazards. It is safer to use and more comfortable.

[0030] In some embodiments, the included angle between the first support portion 11 and the second support portion 12 is 8 to 13 degrees. The angle is reasonably designed, so that users can have a good riding comfort whether they are using it normally or when bandaging their legs.

One end of the first connecting rod 21 is rotatably connected to one of the side brackets 3, and the other end of the first connecting rod 21 is connected to one of the seat support tubes 1. One end of the second connecting rod 22 is rotatably connected to another side bracket 3, and the other end of the second connecting rod 22 is connected to another seat support tube 1.

[0034] Specifically, the connecting frame 2 has an X-shaped structure that provides a folding function for the wheelchair. After removing the seat, the wheelchair can be folded by rotating the first connecting rod 21 and the second connecting rod 22, making it easy to store and use.

[0035] In some embodiments, the connecting frame 2 further includes two support rods 23. One end of one support rod 23 is rotatably connected to one of the side supports 3, the other end of one support rod 23 is rotatably connected to a first connecting rod 21, one end of the other support rod 23 is rotatably connected to another side support 3, and the other end of the other support rod 23 is rotatably connected to a second connecting rod 22. Specifically, by setting the support rods 23, the support function can be better provided, making the overall structure of the wheelchair more stable.

[0036] In some embodiments, the side bracket 3 includes a support rod 31 and a support block 32. The support block 32 is disposed on the support rod 31 and is used to support the seat support tube 1. Specifically, for easy folding, the seat support tube 1 and the support block 32 can be separated. After installation, the seat support tube 1 is supported by the support block 32, resulting in better support.

[0037] In some embodiments, the support rod 31 includes a first support section 311 and a second support section 312. The first support section 311 is horizontally arranged, and the second support section 312 is inclined downward. It can be understood that the shape of the support rod 31 is adapted to the shape of the seat support tube 1, which can provide better stability.

[0038] In some embodiments, the first support segment 311 is arranged parallel to the first support portion 11, and the second support segment 312 is arranged parallel to the second support portion 12. The shape of the support rod 31 is adapted to the shape of the seat support tube 1, which can provide better stability.

[0039] In some embodiments, the support rod 23 is provided with a relief groove 231. The shape of the relief groove 231 is adapted to the shape of the support rod 31. After folding, the position of the relief groove 231 can be locked onto the support rod 31. In addition to the relief effect, it can also play a certain role in preventing the frame from falling apart.

[0040] In some embodiments, the number of connecting brackets 2 is two, which provides better support.

[0041] In some embodiments, the wheelchair also includes a seat plate that supports the seat plate support tube 1 and conforms to the seat plate support tube 1. The seat plate can be a rigid material that matches the shape of the seat plate support tube 1, or it can be a soft cushion that can better fit the shape of the seat plate support tube 1 and make it more comfortable for the user to sit on.
