Abstract

A buffering and damping mechanism of a walking air wheelchair comprises a frame (1), a seat (2), a damping device (3), rear wheels (4) and front wheels (6), wherein the damping device (3) is composed of a damper (12) and a damping spring (11) and disposed between the wheelchair front wheels (6) and the frame (1). The mechanism is characterized in that the upper end and the lower end of the damping spring (11) are fixed on an upper supporting plate (10) and a lower supporting plate (13) of the damper (12) respectively; a hydraulic system with a buffering function is disposed inside the damper (12); and threads (9) and threads (14) are disposed on the upper part and the lower part of the damper (12). According to the invention, the structure is simple; manufacture cost is low; jolting and shaking ranges of the wheelchair can be effectively reduced during walking; and the mechanism is characterized by high safety, high comfort and convenient carrying, etc.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a shock-absorbing mechanism for the cushioning of a walking aid wheelchair. Background technique [0002] As a special medical device, the walking aid wheelchair is designed to serve specific groups of people or the elderly, especially for people with limited mobility. It is not only a means of transportation, but more importantly, it can travel and participate in wheelchairs. social activity. At present, although the existing wheelchairs on the market have solved the travel problem, their riding comfort still needs to be improved. Because there is no cushioning and shock-absorbing device on the front wheels of traditional wheelchairs, the wheelchair cannot cushion and absorb shocks when it encounters uneven roads or road conditions. The user is injured, and there is a certain potential safety hazard. Contents of the invention [0003] Aiming at the deficiencies in the prior a...
