The invention provides an automatic-control elevating mechanism for a bed. The automatic-control elevating mechanism comprises upper supports, columns, lower supports, rotary shafts of the elevating mechanism, a connecting rod, an electric push rod, a motor, optoelectronic switches and a photoelectric controller. The upper support is fixedly connected with a bed plate. The columns are located among the upper supports and the lower supports. Two ends of each column are rotatably connected with one upper support and one lower support. The lower supports are fixedly arranged to a bed frame. Each rotary shaft of the elevating mechanism is located between one column and one lower support. Two ends of each rotary shaft are fixedly connected with two columns. The electric push rod is movably connected with one swing rod. The swing rods are fixedly connected with the rotary shafts of the elevating mechanism. The connecting rod is connected with the rotary shafts of the elevating mechanism in order to keep the mechanism to elevate synchronously. The optoelectronic switches and the motor are connected with the photoelectric controller. The motor is connected with the electric push rod. The automatic-control elevating mechanism for the bed has following beneficial effects: the electric push rod is used for adjusting height of a bed body; only by shielding and breaking off photoelectric control circuits on either side around a treatment bed, height adjustments can be made; and only by treading any foot-controlled pedal on two sides of the treatment bed, the bed can move horizontally in a convenient and rapid mode.
