Abstract
The utility model discloses a wheelchair standing and sitting mechanism. The wheelchair standing and sitting mechanism is arranged on an electric wheelchair provided with a wheelchair frame, driving wheels, a driving motor, universal wheels and a seat. The wheelchair standing and sitting mechanism comprises a driving mechanism and a transmitting mechanism, wherein the driving mechanism and the transmitting mechanism are arranged below the seat and used for driving the seat to lift and move forwards and backwards. The driving mechanism is a straight-line motion mechanism. The transmitting mechanism is hinged and fixed to the seat. The transmitting mechanism is driven by the driving mechanism to swing in the circumferential direction with one end fixed and hinged to the wheelchair frame serving as a center of a circle. In the process of swinging, the seat can be gradually conveyed forwards and upwards. The process of standing and sitting is steady, the center of the gravity of the human body is changed constantly, and therefore a user can stand up by means of being pushed by the wheelchair standing and sitting mechanism and vice versa. The user can stand up and sit down conveniently by oneself for exercise, so that the standing and sitting difficulty of the user is reduced and the electric wheelchair is humanized. The stroke of the driving mechanism can be adjusted according to the requirements of the user. The swinging range of the transmitting mechanism is adjusted. The wheelchair standing and sitting mechanism is simple in structure, convenient to install and use and low in cost.
