A multi-directional barrier-free wheelchair

Abstract

The invention discloses a multidirectional barrier-free wheelchair, which relates to the technical field of medical wheelchairs. The invention comprises a bracket mechanism, wherein a seat cushion mechanism is fixed on the bracket mechanism, wheel rims are fixed on an opposite sides of the seat cushion mechanism, a support mechanism is fixed on the bracket mechanism, the seat cushion mechanism comprises a plurality of seat plates, the bracket mechanism comprises a plurality of first bearings matched with a first roller, and the support mechanism comprises a third roller. By designing a new bracket structure, the handle, the support frame, the universal wheel and the wheel rim of the wheelchair become one whole, the four auxiliary universal wheels are matched with two rims, the support structure can be interchanged, the support plate can rotate along the rotating shaft, and the problem that the wheelchair mechanism is single, can only be used in one direction, the steering is restricted, the use is inconvenient, the bracket is independent, and the overall connection is not strong is solved.

Description

technical field [0001] The invention belongs to the technical field of medical wheelchairs, in particular to a multidirectional barrier-free wheelchair. Background technique [0002] The wheelchair is an important tool for rehabilitation. It is not only a means of transportation for the physically disabled, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of wheelchairs. Ordinary wheelchairs are generally composed of four parts: wheelchair frame, wheels, brake device and seat. In the world-recognized history of wheelchairs, the earliest record is the sculpture of a chair with wheels on the sarcophagus of the Northern and Southern Dynasties in China, which is also the predecessor of the modern wheelchair. [0003] Most of the existing wheelchairs have a single mechanism and are not very convenient to use, and can only be used in one direction; when the user uses it alone, it is inconvenient to get on and o...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-directional barrier-free wheelchair. By designing a new bracket structure, the handle, support frame, universal wheel and rim of the wheelchair are integrated into a whole, and four auxiliary universal wheels are matched with two wheels. The supporting structure can be interchanged, and the supporting plate can rotate along the rotating shaft, which solves the problem that most of the existing wheelchairs have a single mechanism and can only be used in one direction. The structural stability of the wheelchair is not strong, and it is easy to lean forward and backward when going up and down slopes. Steering is limited and the overall connectivity is not strong, resulting in insufficient strength
