Bed structure
A bed structure includes a bedstead formed by bedstead units. The bedstead units are symmetrically arranged with respect to the central axis of the bedstead. The bedstead unit includes a first bedstead unit and a second bedstead unit. The first bedstead unit is hinged to the second bedstead unit. A motor is provided between the first bedstead unit and the second bedstead unit. The bedstead units at both sides of the central axis of the bedstead are hinged by a fixing rod. Each of two ends of the fixing rod is provided with a clamping member. The bedstead unit is provided with a matching member connected to the clamping member. The clamping member and the matching member are hinged by a fastener. In this arrangement, the electric bed can be folded.
