The invention discloses an electric round bed. The electric round bed comprises a main frame. A plurality of electric units are arranged on the periphery of the main frame at equal intervals. Each electric unit comprises a hinged frame on the periphery of the main frame, a rotating frame hinged to the end of the hinged frame and a driving device arranged on the main frame and used for driving the rotating frame to turn over horizontally, wherein the hinged frame and the rotating frame are fixed at two ends of a first hinge correspondingly, a driving shaft of the driving device drives the end, connected with the rotating frame, of the first hinge and makes the rotating frame turn over horizontally relative to the main frame, the two sides of the first hinge are each provided with a second hinge, and the two ends of each second hinge are fixed to the hinged frame and the rotating frame correspondingly. The electric round bed has the advantages of being capable of safely protecting an infant moving or taking rest in the electric round bed, simple in structure, and foldable, thereby fully according with human engineering.
