The invention discloses a concave-convex electric bed for correcting kyphosis and hunchback. The concave-convex electric bed comprises a crank and connecting rod mechanism, a motor, a brake, a waved mattress and a bed. The waved mattress is mounted on the upper portion of the bed, the crank and connecting rod mechanism, the motor and the brake are mounted in the bed, the motor is connected with the crank and connecting rod mechanism and the brake, a control panel is arranged outside the bed, the crank and connecting rod mechanism, the motor and the brake can be controlled by the control panel, the crank and connecting rod mechanism comprises cranks, crank necks and crank arms, the crank arms include circumferential crank arms and inner swing crank arms, the cranks are connected with the crank arms and are connected with the crank necks by bearings, and one end of each crank neck is fixed onto the bed. The concave-convex electric bed has the advantages that the concave-convex electric bed is reasonable in design, simple in structure and easy and convenient to use, hunchback positions can be discontinuously struck and massaged by the waved mattress, accordingly, the kyphosis or the hunchback can be obviously improved, and even patients can be recovered; the concave-convex electric bed is high in practicality and low in manufacturing cost and has a broad market prospect.
