In a process of pushing the wheelchair mechanism into the inner side of the bed body mechanism, a limiting member releases locking of a driving member, at the same time, the driving member drives a lifting member to move downward, the lifting member drives downward to drive a backup plateto turn downward through a connecting member, at the same time, and an L-shaped pedal is turned up automatically form a horizontal bed plate. During a process of pushing the wheelchair mechanism out of the inner side of the bed mechanism, the driving member drives the lifting member to move upward, the lifting member moves upward to drive the backup plate to turn upward through the connecting member, at the same time, the L-shaped pedal is turned down to automatically form a chair body, and besides, the limiting member automatically locks the driving member, thereby ensuring stability of the chair body shape.
