Low Bed Structure for Car

Abstract

A low bed structure for a car includes an inner frame, a bed board and a lifting device. The lifting device is mounted on the inner frame and includes a motor mounted on a center of the top bracket, a retractable rod connected with the motor, and a linking piece having a first end connected with the retractable rod and a second end connected with a substantially H-shaped support rack. In practice, the motor is operated to move the retractable rod which drives the H-shaped support rack to produce an angle variation of the H-shaped support rack so as to lift or lower the bed board. Thus, the motor is mounted on the top bracket of the inner frame and will not swing with the bed board.
