Abstract

The invention discloses a walking aid wheelchair buffering and damping mechanism which comprises a bottom plate. Side plates are arranged on the front side and the rear side of the upper surface of the bottom plate, a back plate is arranged on the left side of the upper surface of the bottom plate, a back cushion is arranged on the right side of the back plate, the right side of the bottom plate is connected with the top end of a connecting rod, the bottom end of the connecting rod is connected with a pedal, the left side of the bottom of the bottom plate is connected with the top end of a second damper, the bottom end of the second damper is connected with a fixed plate, a second damping spring is arranged on the outer side of a second damper, a rotating shaft is arranged on the bottom surface of the fixed plate, and a rear wheel is arranged on the rotating shaft and rotatably connected with the rotating shaft. The mechanism is simple in structure, reasonable in design, a buffering and damping device is arranged between a wheelchair wheel and a frame, so that vibration from the ground can be effectively relieved, vibration energy can be timely absorbed and relieved when a wheelchair drives on a rough or bumpy road, bumping and shaking amplitudes of the wheelchair in driving are effectively reduced, and the mechanism has the advantages of safety and comfort in use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cushioning and shock-absorbing mechanism 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] The technical problem to be solved ...
