The utility model relates to an electric bed, which comprises a base and a power source.The base is provided with a sliding seat, which allows a connecting plate frame, a foot plate frame and a pull rod to swing and connect to the same end of the sliding seat.The foot plate frame is provided with a support plate, and a long hole is formed in the support plate.The pull rod has two boycott wheels, two main rods and a base, the boycott wheel is pivoted on the main rod, and the axle part passes through the long hole of the support plate.The power source is connected to the sliding seat and can swing, which drives a driving part to engage in telescopic movement, and the driving part is connected with the base.When the power source is started, the driving part drives the draft rod to rotate, and the main rod drives the wheel shaft to move in the long hole, which supports the foot plate frame to move from the drooping state to the horizontal state.When the wheel axle is blocked on the wall surface of the long hole, the main rod supports the height of the foot plate frame, and the support connecting plate frame keeps an angle of inclination with respect to the sliding seat.一種電動床,包括:一底座與一動力源。在底座配置一滑座,允許一連接板架、一腳板架與一牽制桿可擺動的連接於滑座的同一端。該腳板架有一支撐片,在支撐片形成一長孔。該牽制桿有二抵制輪、二主桿與一基座,該抵制輪樞接於主桿上,而且輪軸部位通過支撐片的長孔。該動力源連接於滑座而可擺動,其驅使一驅動件從事伸縮運動,該驅動件與基座相連。當動力源啟動,該驅動件帶動牽制桿轉動,連帶主桿驅使輪軸部位在長孔位移,支持腳板架從下垂狀態來到水平狀態。在輪軸部位受阻於長孔壁面時,該主桿撐高腳板架的高度,支撐連接板架相對滑座保持一角度的傾斜。
