Abstract: An electric bed has a first bed board and a second bed board, which are hinged with each other, and a bed frame, a head bracket, a head driving motor, and a head pull rod. The bed frame has an upper bed frame and a lower bed frame. The second bed board and the upper bed frame are fixedly connected in a dismountable mode. The upper bed frame and the lower bed frame are connected by a guide rail connecting structure so that the upper bed frame can move relative to the lower bed frame. One end of the head bracket is hinged with the bed frame and another end of the head bracket is supported against the first bed board.

Abstract: An electric bed has a bed frame, multiple boards, and a motor structure. The bed frame comprises a lower bed frame and an upper bed frame, and the upper bed frame and the lower bed frame are connected by a connecting structure. The multiple boards are hinged, and at least one board is fixed onto the upper bed frame. The motor structure comprises a connecting rod, a slide bar, and a horizontal pushing motor system. The connecting rod has one end hinged with the first board of the multiple boards. The slide bar extends in the width direction of the bed frame and is arranged in a sliding chute in the length direction of the bed frame, so that it can slide along the length direction of the bed frame.

Abstract: A reciprocating ejector mechanism for an electric bed comprising an aperture formed on a bed board. An ejector mechanism is mounted in the aperture. The ejector mechanism includes an ejected part, which is arranged parallel to the bed board. At least one first connecting rod with one end is connected with the ejected part and another end is hinged with a slider. The slider may slide along the guide bar fixed on the bed board. A second connecting rod with one end can be hinged with the middle part of the first connecting rod and another end hinged with the bed board. The ejector mechanism may have a driving device fixed on the bed board and connected with the linkage to drive the first connecting rod to rotate, so that the ejected part is driven to move parallel to the bed board.

Abstract: An electric bed with a sliding block linkage has a head board, an inner frame, an outer frame, and a head supporting part. Two ends of the head supporting part are in rotatable connection with the head board and the outer frame. The inner frame is in sliding connection with the outer frame. The head board is in rotatable connection with the inner frame. A sliding block linkage has a driving device used for driving the inner frame to move relative to the outer frame. Relative sliding in a horizontal direction controls a horizontal movement distance of the head board. Optionally, the inner frame is positioned on the outer frame and movably connected with it by a sliding chute. The inner frame is driven by a motor to horizontally move relative to the outer frame.

Abstract: An electric motorized bed has a bedframe, and multiple bed boards. The bedframe includes an upper bedframe and a lower bedframe. The upper bedframe and lower bedframe are connected by a guide rail. Multiple bed boards are connected to each other and one bedboard is connected to the bedframe. The slider motor system has a connecting rod. The slider motor systems two sides are connected to the lower bedframe. The slider motor system has a slider connecting with one of the bed boards using a connecting rod. The slider motor system has a slider that can move between a nonmovable position and a movable position. In the nonmovable position there is another bed board positioned horizontally. In the movable position, another bedboard is positioned to be capable of being raised and lowered. Another bedboard can be positioned at any location between the horizontal position and a vertical moving position.

Abstract: A lumbar folding bed includes a bed frame, and a board assembly that has a calf board, a thigh board pivotally mounted to the calf board, a seat board pivotally mounted to the thigh board, and a back board pivotally mounted to the seat board. A lumbar extension motor is connected to the board assembly. A lumbar extension rod is mechanically linked to the lumbar extension motor. The lumbar extension motor is configured to raise and lower the lumbar extension rod. A pair of calf board massagers are mounted to the calf board. The pair of calf board massagers includes a left calf board massager and a right calf board massager. The lumbar folding bed further optionally includes a pair of back board massagers.
