DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The bottom end of the support block 7 located on the outer part is rotatably connected with a roller 8. A locking slot 9 is provided inside the wheelchair body 1 above the telescopic slot 5. The locking slot 9 is communicated with the telescopic slot 5. An electric push rod 10 is installed on the inner top wall of the locking slot 9. Two blocks 11 are fixed to the output end of the electric push rod 10. Two slots 12 adapted to the blocks 11 are provided on the top of the support block 7. A controller body 13 is installed on the wheelchair body 1. The first motor 2 and the electric push rod 10 are electrically connected to the controller body 13.

[0023] When the wheelchair controller is in use, when the wheelchair stops and the operator leans on it, or when climbing a slope, the controller body 13 is manipulated to make the electric push rod 10 drive the card block 11 to move upward, so that the card block 11 is separated from the outer card slot 9, and the first motor 2 is started to drive the first threaded rod 4 to rotate. The slider 6 threadedly connected to the first threaded rod 4 moves outward along the sliding slot 3, and the slider 6 drives the support blocks 7 on both sides to move outward along the telescopic slot 5, and the support block 7 drives the roller 8 to move. When the inner card slot 9 moves to the bottom of the card block 11, the electric push rod 10 is started again to drive the card block 11 to move downward, so that the card block 11 is inserted into the inner card slot 9 to fix the support block 7. The roller 8 and the support block 7 support the wheelchair, effectively preventing it from tipping over.

[0024] It is found in actual use that the roller 8 will be worn out after long-term use of the wheelchair and needs to be disassembled, replaced and repaired, but the disassembly operation is not easy to perform.

The rotating shaft 14 passes through the support block 7 and the roller 8, and a fixing block 15 is threadedly connected to the rotating shaft 14, and the fixing block 15 is provided with anti-slip grooves.

[0025] It is found in actual use that in order to reinforce the structure of the anti-turnover mechanism, in this embodiment, a reinforcement plate 16 is fixed on the outer portion between the two support blocks 7 .

[0026] It is found in actual use that the support block 7 will shake in the telescopic slot 5 when supporting the wheelchair. In order to avoid the above problem, in this embodiment, the telescopic slot 5 is provided with a cross shape, and the support block 7 is adapted to the telescopic slot 5.

[0027] It is found in actual use that the controller body 13 is exposed on the surface and is easily wetted by rain, resulting in a short circuit. In order to avoid the above problem, in this embodiment, a waterproof cover 17 is slidably connected to the controller body 13, and the waterproof cover 17 is set to a transparent material.

[0028] It is found in actual use that the roller 8 made of a harder material will cause the wheelchair to be bumpy when traveling. In order to solve the above problem, in this embodiment, the roller 8 is made of rubber material.
