The invention relates to the technical field of wheelchairs, in particular to a
wheelchair with a rear wheel
damping function, which comprises a frame, one end of the frame is connected with a front wheel group, the other end of the frame is connected with a rear wheel group, and a damping structure and a parking mechanism are arranged on the frame; when the
wheelchair is in dynamic use, the seat
cushion on the frame is in a dynamic bearing state, a supporting arm in the damping mechanism presses down a
damper in a clearance mode, and the supporting arm presses down or ascends to drive an upper
rocker arm and a lower
rocker arm to turn over up or down on a vertical
rocker arm; the inclined angle of the
shock absorber relative to the horizontal plane in the rectangular framework is increased or decreased, the
shock absorber of the shock absorption mechanism carries out inclined positive and negative rigidity back-and-forth switching supporting on the frame, the frame absorbs and relieves vibration transmitted by the rear wheel set through the shock absorption mechanism, and therefore
impact force between the rear wheel set and the
road surface is effectively absorbed, shaking of the frame is reduced, and the service life of the frame is prolonged. The stability of the frame is improved, the influence of shaking on a user sitting on the
wheelchair is reduced, and the comfort of the user is improved.
