Technical Field

[0001] The utility model relates to the technical field of wheelchairs, in particular to a wheelchair with an auxiliary structure. Background Art

[0002] A wheelchair is a seat used to replace walking or to help people with limited mobility to move. Wheelchairs usually have four wheels and are equipped with manual or electric propulsion. There are also some specially designed wheelchairs suitable for different needs. The seat and backrest of the wheelchair are usually padded for comfort and can be adjusted according to personal needs. Wheelchairs are suitable for people with limited mobility, disabilities, rehabilitation or short-term injury recovery to provide convenient, safe and independent mobility.

[0003] However, the existing smart wheelchairs for the elderly do not have a toilet-assisting structure when in use. Since elderly patients have difficulty in getting up due to leg problems, they cannot stand up, so they need outsiders to assist them in going to the toilet, which increases the difficulty for them to go to the toilet.

When the movable disk 312 rotates, it will drive the long rod 313 and the short rod 314 to rotate. When the long rod 313 rotates, it will resist the upper triangular block 35 and drive the upper triangular block 35 to slide upward. When the upper triangular block 35 slides up and down, it will drive the groove block 33 to slide upward on the surface of the long block 31, thereby driving the collecting block 317 to slide upward to the bottom of the fixing ring 41. When the groove block 33 slides to the top of the long block 31, the lower triangular block 35 will resist the card The top of the hook 38 is restricted. When the movable disk 312 rotates again, the short rod 314 will be used to resist the clamping rod 39, thereby driving the clamping hook 38 to rotate counterclockwise. When the clamping hook 38 rotates counterclockwise, the restriction on the groove block 33 will be released, and the collection block 317 will slide down. When the elderly patient finishes using the toilet, the rotation of the movable shaft 319 can be driven by rotating the T-shaped telescopic rod 320. When the movable shaft 319 rotates, it will drive the collection block 317 to rotate, thereby facilitating the cleaning of the collected materials inside the collection block 317 and improving the cleanliness of the elderly patient when using the toilet.
