[0002] Electric beds, as a convenient and comfortable type of bedding, are widely used in homes, hospitals, and nursing homes. Electric beds typically use a drive mechanism to raise, lower, fold, or tilt the bed boards (back and leg sections) to meet the user's different posture needs. However, in the use of existing electric beds, when the bed board is raised, a certain angular gap is created between the movable bed board and the bed frame, or between the bed boards themselves (in a bunk bed). When the bed board is lowered, if the user's hands, arms, legs, feet, or a pet gets caught in this gap, it can lead to injury, and in severe cases, even personal injury.
[0003] In existing technologies, to prevent users from being injured by the bed board, some electric beds use soft padding to prevent hand pinching; others use anti-pinch strips for active anti-pinch protection. However, these anti-pinch methods all have certain limitations, such as installation location, low sensitivity, and unstable anti-pinch effect.
[0004] Therefore, a simple, responsive, and highly reliable anti-pinch bed board, double bed, and electric bed need to be designed. Utility Model Content

In addition, the first, second, etc. words are only for distinguishing a plurality of components or structures with the same or similar structures, and do not mean a certain special limitation on the arrangement order or connection relationship.
[0047] Please refer to Figures 1 to 9 , the present application embodiment provides an anti-pinch bed board 100, which comprises a fixed bed board 1, a movable bed board 2, a trigger switch device and a controller (not shown in the figure).
[0048] The fixed bed board 1 is used to be installed on the electric bed frame 300, for example, the fixed bed board 1 can be assembled at the back position and / or leg position of the electric bed frame 300 to realize the swing lifting motion under the driving of the driving device 310 of the electric bed frame 300.
[0049] One movable board 2 is rotatably connected with one side of the fixed bed board 1 through the elastic hinge connecting piece to be folded when being pressed by external force. It can be understood that in some embodiments, when the electric bed has only one electric bed frame 300, two movable boards 2 can be arranged, and the two movable boards 2 are rotatably connected with the two sides of the fixed bed board 1 through the elastic hinge connecting piece. In other embodiments, when the electric bed is a double bed 1000, that is, two electric bed frames 300 are arranged in the bed enclosure 200, only one movable board 2 can be arranged on the side adjacent to the fixed bed board 1 of the double bed 1000, and no movable board 2 is arranged on the side away from each other of the two fixed bed boards 1. Of course, it can be understood that the movable boards 2 can also be arranged on the two sides of the fixed bed board 1 of the double bed 1000, respectively. Alternatively, in other embodiments, the movable board 2 arranged on one side of the fixed bed board 1 can also be composed of multiple small movable boards 2, which is not limited in particular.
[0050] The trigger switch device is arranged between the movable board 2 and the fixed bed board 1, and has an open circuit state and a conduction state. The open circuit state is a state in which the trigger switch device is not triggered when the movable board 2 is not pressed by external force, and the conduction state is a state in which the trigger switch device is triggered and outputs an electrical signal when the movable board 2 is folded by external force.
[0051] The controller is electrically connected with the trigger switch device and the driving device 310, and is used to receive the electrical signal to control the driving device 310 to stop or reverse. Specifically, the controller can be fixed on the back of the fixed bed board 1 and the movable board 2, or on the electric bed frame 300, and is electrically connected with the trigger switch device and the driving device 310 through wires (not shown in the figure). It can be understood that the controller receives the electrical signal to control the driving device 310 to stop or reverse, which belongs to the prior art, and therefore will not be described in detail here.
[0052] In this way, when the bed board is lowered, if the gap between the movable board 2 and the bed frame or between the two movable boards 2 presses the body part of the user, the movable board 2 will be pressed and folded, the trigger switch device will be triggered and output an electrical signal, and the controller will receive the electrical signal to control the driving device 310 to stop or reverse, so that the user can be effectively prevented from being pressed and injured during the operation of the electric bed. The anti-pinch bed board 100 has a simple structure, a stable and reliable connection mode, and the trigger switch device has a sensitive response.
[0053] Optionally, please refer to Figures 6 to 9In the embodiment, the trigger switch device is a micro switch 4. The button 41 of the micro switch 4 is pressed in the off state, and the button 41 of the micro switch 4 is released and outputs an electrical signal in the on state. The button 41 of the micro switch 4 is released, that is, the trigger signal is output, so that the driving device 310 is quickly stopped or reversed to prevent pinching, and the micro switch 4 has the advantage of sensitive trigger response. In addition, the circuit is disconnected when the button 41 of the micro switch 4 is pressed, and the circuit is connected when the button 41 is released, which can effectively avoid false triggering.
[0054] Optionally, please refer to Figures 3 to 5 In the embodiment, the elastic hinge connector is a spring hinge 3, so that the movable plate 2 is folded when subjected to external pressure and automatically returns to the horizontal state when the external force is removed. In this way, the reset mechanism can be avoided, and the movable plate 2 can automatically return after the external force is removed, so that the micro switch 4 returns to the off state. That is, the spring hinge 3 is used to simplify the structure of the anti-pinch bed board 100 and reduce the manufacturing cost.
[0055] In order to avoid that in the off state, the spring hinge 3 protrudes from the side of the fixed bed board 1 and the movable plate 2 supporting the mattress and lifts the mattress (not shown in the figure). Optionally, please refer to Figure 4 In the embodiment, the side of the fixed bed board 1 and the movable plate 2 supporting the mattress is provided with a hinge assembly groove a, and the two hinge pieces 31 of the spring hinge 3 are assembled in one of the hinge assembly grooves a, so that the spring hinge 3 is embedded in the supporting surface. In this way, in the off state, the spring hinge 3 is located in the hinge assembly groove a. Specifically, the spring hinge 3 is assembled in the hinge assembly groove a by a round head screw 5. Of course, in other embodiments, the spring hinge 3 can be snap-fitted in the hinge assembly groove a, or the spring hinge 3 can be installed on the side of the fixed bed board 1 and the movable plate 2 away from the mattress, which is not limited here.
[0056] Optionally, please refer to Figure 8 In the embodiment, the side of the fixed bed board 1 close to the movable plate 2 has a switch assembly groove b, and the micro switch 4 is assembled in the switch assembly groove b. Specifically, the micro switch 4 is assembled in the switch assembly groove b by a round head self-tapping screw 6.
[0057] Optionally, please refer to Figure 8 In the embodiment, the switch assembly groove b is provided on the side of the fixed bed board 1 away from the hinge assembly groove a. In this way, the human body and the mattress can avoid pressing the micro switch 4 to cause false triggering, and the micro switch 4 can be prevented from being pressed for a long time to prolong its service life.
[0058] Please refer to Figure 1 and Figure 2In another aspect, the utility model provides a double bed 1000, include: bed 200 and two electric bed frame 300. Two electric bed frame 300 are arranged in parallel in bed 200, and the back bed board of each electric bed frame 300 is the anti-pinch bed board 100 as described above. Since the double bed 1000 has all the structures and connection relationships of the anti-pinch bed board 100, it has all the advantages of the anti-pinch bed board 100, which will not be repeated here.
[0059] In another aspect, the utility model provides an electric bed (not shown in the figure), including: bed and electric bed frame. Electric bed frame is arranged in bed, and the back bed board of electric bed frame is the anti-pinch bed board 100 as described above. Since the electric bed has all the structures and connection relationships of the anti-pinch bed board 100, it has all the advantages of the anti-pinch bed board 100, which will not be repeated here.
