1. A foldable bed, comprising:
a bed frame structure having:
a back frame and a leg frame connecting to the back frame such that the back frame and the leg frame are pivotally foldable relative to one another along a length direction of the foldable bed, wherein each of the back frame and the leg frame comprises a pair of side rails, and an upper rail and a lower rail connected to the pair of side rails in a rectangle form, and wherein the back frame further comprising a crossbar connected to the pair of side rails and positioned between the upper rail and the lower rail;
a back lifting bracket pivotally connected to the crossbar of the back frame;
a leg lifting bracket comprising a first lifting bracket pivotally connected to the upper rail of the leg frame, and a second lifting bracket pivotally connected to the first lifting bracket, wherein the second lifting bracket is provided with supporting legs pivotally connected to the pair of side rails of the leg frame;
a back lifting actuator pivotally connected between the back lifting bracket and the back frame for operably driving the back lifting bracket to pivotally move in an upward rotating direction or a downward rotating direction relative to the back frame;
a leg lifting actuator pivotally connected between the leg lifting bracket and the leg frame for operably driving the leg lifting bracket to pivotally move in an upward rotating direction or a downward rotating direction relative to the leg frame;
wherein each of the back and leg lifting actuators comprises a motor member, an outer tube extending from the motor member, and an activation rod having a first end portion received in the outer tube and an opposite, second end portion, wherein the activation rod is engaged with the motor member and configured to be telescopically movable relative to the outer tube according to a direction of motor rotation, wherein the second end portion of the activation rod of the back lifting actuator is pivotally connected to the back lifting bracket, and the second end portion of the activation rod of the leg lifting actuator is pivotally connected to the leg lifting bracket;
a motor fixing bracket detachably connected to the back frame and the leg frame, wherein the motor members of the back and leg lifting actuators are pivotally connected to first and second ends of the motor fixing bracket, respectively; and
a plurality of boards detachably attached onto the bed frame structure along the length direction of the foldable bed, wherein each board comprises a pair of panels arranged along a width direction of the foldable bed.
