Standing bed with standing and squatting training function and ankle joint training function

The invention discloses a standing bed with a standing and squatting training function and an ankle joint training function. The standing bed comprises a bed body support frame, a movable bed surface which forms a revolving pair with the bed body support frame, a first linear actuator and a first buffer, and the two ends of the first linear actuator and the two ends of the first buffer are hinged to the back face of the movable bed surface and the bed body support frame respectively; a moving bed surface is arranged on the upper portion of the movable bed surface, sliding between the movable bed surface and the moving bed surface is achieved through a longitudinal linear guide rail, a second linear actuator and a second buffer are arranged, one end of the second linear actuator and one end of the second buffer are both hinged to the movable bed surface, and the other end of the second linear actuator and the other end of the second buffer are both hinged to the back face of the moving bed surface; pedal support frames are arranged at the bottom end of the movable bed surface, and the middle rear part of the bottom face of a pedal and the corresponding pedal support frame form a revolving pair; a third linear actuator is arranged, one end of the third linear actuator is hinged to the bed body support frame, a connecting rod is hinged to the other end of the third linear actuator, and the connecting rod is hinged to the front ends of the bottom faces of the pedals. By means of the standing bed with the standing and squatting training function and the ankle joint training function, the defects in the prior art are effectively overcome, a convalescent patient can conduct standing and squatting training and can also conduct ankle joint training.
