Abstract

The invention relates to an angle controllable reclining and vertical electrical wheelchair with any sitting postures. A linear motor transmission module comprises a linear motor, a wheel frame and a sitting frame. The linear motor is connected between the wheel frame and the sitting frame. A sleeve of the linear motor is in transmission connected with a lower transverse rod of the wheel frame and a mandrill of the linear motor is in transmission connected with a middle transverse of the sitting frame. A servo motor transmission module comprises a servo motor, a reduction box, and a chain-chain wheel box, a self-locking mechanism installed in the servo motor, a leg rest and a backrest. The servo motor and the reduction box are fixed on the sitting frame and connected with a transmission shaft of the chain-chain wheel box close to the leg rest. One end of the transmission shaft of the chain-chain wheel box is connected with a rotating shaft of the leg rest and the rotating shaft of the leg rest is connected with a rotating shaft of the sitting frame. The other end of the transmission shaft of the chain-chain wheel box is connected with a rotating shaft of the backrest and the rotating shaft of the backrest is connected with the sitting frame through a bearing. With the adoption of the invention, the user can switch among the sitting position, the lying position and the standing position according to demand and the invention can be used for the user with moderate lower limb training according to demand.

Description

technical field [0001] The invention relates to an electric wheelchair, in particular to an electric wheelchair capable of enabling a patient to stand and lie flat.
