Shock absorbing wheel chair

Abstract

The invention provides a shock absorbing wheel chair which comprises a wheel chair rack, a seat, two shear type shock absorbing mechanisms, a pair of back wheels, a front wheel shock absorbing mechanism, side plates, a wheel rack and shock absorbing springs I. The two side plates are oppositely arranged on two sides of the wheel chair rack, the back wheels are movably mounted in the two side plates through two wheel racks separately, the shock absorbing springs I are arranged between the wheel racks and the side plates, the seat is movably mounted on the wheel chair rack, the shear type shockabsorbing mechanisms are arranged on the lower side of the seat, and the two shear type shock absorbing mechanisms are oppositely mounted on the wheel chair rack. By arranging the pair of shear type shock absorbing mechanisms to absorb shock below the seat, the purpose of increasing the shock absorbing effect is achieved by way of multi-shock-absorbing mode. Shock from the wheels is weakened through the front wheel shock absorbing mechanism. In the advancing process of the front wheel on a rugged pavement, the front wheel can shrink inward to buffer so as to further reduce shock. The front wheel shrinks when the wheel chair encounters a relatively low ladder, so that the wheel chair advances favorably.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a shock-absorbing wheelchair. Background technique [0002] At present, with the continuous improvement of living standards, people's life expectancy is getting longer and longer, and people pursue high-quality life. Especially the disabled, the sick and the elderly and infirm move indoors and outdoors. They need to use wheelchairs. The wheelchairs used by the vast majority of people are only moved by their own propelling force or the propelling force of the people behind them. However, although such a wheelchair solves the travel of the disabled, it does not completely solve the travel comfort problem of the patient and the elderly and infirm, so designing a wheelchair with a shock-absorbing function can effectively solve the problem that the wheelchair runs into uneven roads or poor road conditions.

[0003] Publication No. CN108078698A provides a cushioning and shock-absorbing mechanism for a walking aid wheelchair, including a bottom plate, the upper surface of the bottom plate is provided with a cushion, the front and rear sides of the upper surface of the bottom plate are provided with side plates, and the left side of the upper surface of the bottom plate is provided with a back plate , the right side of the backboard is provided with a cushion, the right side of the bottom board is connected with the top of the connecting rod, the bottom of the connecting rod is connected with the pedal, the left side of the bottom of the bottom board is connected with the top of the second shock absorber, and the second shock absorber The bottom end of the device is connected with the fixed plate, the second shock absorber is provided with a second damping spring on the outside, the bottom surface of the fixed plate is provided with a rotating shaft, the rotating shaft is provided with a rear wheel, and the rear wheel is rotatably connected with the rotating shaft. The universal wheel is provided with a first shock absorbing spring, and the rear wheel is provided with a second shock absorbing spring. Since the universal wheel is directly connected with the first shock absorbing spring, the universal wheel will It is easy to swing, and then it cannot be well damped, and this damping mechanism only uses the wheel for shock absorption, and the seat surface cannot perform shock absorption
