The backrest push rod drives the movement of the backrest tilting plates, enabling functions such as back lifting and tilting.

[0035] Specifically, Figure 3 and Figure 4 This is a schematic diagram of the bed device in the normal sitting-up state. In the normal sitting-up state, the backrest 12 is connected to the back turning board 13-1 and the back turning board 13-4 and is in a locked state. The leg lifting boards 5-1 and 5-2 are connected to the buttock turning boards 4-1 and 4-4 respectively and are in a locked state. The standing aid boards 3-1 and 3-2 are connected to the buttock turning boards 4-1 and 4-4 respectively and are in a locked state.

The foot push rod 10 retracts and the leg push rod 9 extends, so that the lower leg board 7 and the foot board 8 are in the state shown in the figure.

[0037] Specifically, Figure 1 This is a schematic diagram of the bed device in the turning state. In the turning state, the back turning plate 13-4 is connected to the back plate 12 and is in the locked state. The back turning plate 13-1 is separated from the back plate 12 and is in the unlocked state. The hip turning plate 4-4 is connected to the leg lifting plate 5-2 and the standing aid plate 3-2 and is in the locked state. The hip turning plate 4-1 is separated from the leg lifting plate 5-1 and the standing aid plate 3-1 and is in the unlocked state. The hip push rod 6-1 and the back push rod 14-1 are extended to their longest length. The hip push rod 6-2 and the back push rod 14-2 are extended appropriately. At this time, it is the left turning state. The same applies to turning to the right.

[0038] Specifically, Figure 5This is a schematic diagram of the bed frame in the sitting-up and leg-lifting state. In this state, the backrest 12 is connected to the back turning board 13-1 and the back turning board 13-4 and is locked. The leg-lifting boards 5-1 and 5-2 are connected to the hip turning boards 4-1 and 4-4 respectively and are locked. The standing aid boards 3-1 and 3-2 are separated from the hip turning boards 4-1 and 4-4 respectively and are unlocked.

The foot push rod 10 extends and the leg push rod 9 retracts, so that the calf board 7 and foot board 8 are in the state shown in the diagram. The hip push rods 6-1 and 6-2 extend to rotate the hip turning boards 4-1, 4-2, 4-3 and 4-4, transforming them into the sitting-up and leg-lifting state.

[0039] Specifically, Figure 6 This is a schematic diagram of the bed device in the sitting-to-standing assist state. In the sitting-to-standing assist state, the backrest 12 is connected to the back turning board 13-1 and the back turning board 13-4 and is in a locked state. The leg lifting boards 5-1 and 5-2 are separated from the hip turning boards 4-1 and 4-4 respectively and are in an unlocked state.

The back push rods 14-1 and 14-2 extend to rotate the backrest 12 to lift the backrest. The foot push rod 10 extends and the leg push rod 9 retracts, so that the lower leg board 7 and foot board 8 are in the state shown in the figure. The hip push rods 6-1 and 6-2 extend to rotate the hip turning boards 4-1, 4-2, 4-3 and 4-4, transforming them into the sitting-to-standing assist state.

[0040] Preferably, the connection or separation between components is achieved by a pin-type electromagnetic lock 15.

[0041] Specifically, such as Figure 5 and Figure 6As shown, the connection or separation between components is achieved by using a pin-type electromagnetic lock 15. This mainly relies on the working principle of the electromagnetic lock and the design of its pin mechanism. In this bed device, the connection or separation between the back plate 12 and the back turning plate 13-1 and the back turning plate 13-4, the connection or separation between the leg lifting plates 5-1 and 5-2 and the buttock turning plates 4-1 and 4-4 respectively, and the connection or separation between the standing aid plates 3-1 and 3-2 and the buttock turning plates 4-1 and 4-4 respectively are achieved by using a pin-type electromagnetic lock 15. In addition, round-headed pins 16 are arranged on the back plate 12, the leg lifting plates 5-1 and 5-2, and the standing aid plates 3-1 and 3-2 respectively, and pin holes 17 are arranged on the back turning plates 13-1 and 13-4 and the buttock turning plates 4-1 and 4-4 respectively. When components need to be connected, the electromagnet is activated, causing the round-headed pin 16 to fall into the pin hole 17. The pin-type electromagnetic lock 15 and the round-headed pin 16 then securely connect the components. When components need to be separated, the power supply to the electromagnet is disconnected. As the push rod is pushed, the round-headed pin 16 disengages from the pin hole 17, separating the components. Controlling the connection or separation of components via the pin-type electromagnetic lock 15 improves the convenience of control, while the positioning function of the round-headed pin 16 improves the accuracy of positional control during connection or separation.

[0042] Preferably, the various deformation mechanisms are connected by hinges 18 and locating pins.

[0043] Specifically, such as Figure 1 As shown, hinge connections ensure smooth relative rotation of each deformation mechanism when needed, thereby enabling multi-functional changes in the bed frame. In the hip deformation mechanism, hinge 18 connects components such as the hip base plate 2, the standing aid plate, the hip turning plate, and the leg lifting plate, allowing them to rotate relative to each other and achieve functions such as hip lifting and turning. In the leg and back deformation mechanisms, hinge 18 also connects components such as the lower leg plate 7, the foot plate 8, the back plate 12, and the back turning plate, enabling various posture changes for the legs and back. Positioning pins ensure stable connections between the deformation mechanisms during relative rotation, preventing loosening or misalignment. In the hip, leg, and back deformation mechanisms, positioning pins connect the connection points between components, ensuring accurate relative positions. For example, positioning pins can be used between the hip turning plate and the leg lifting plate, between the lower leg plate 7 and the foot plate 8, and between the back plate 12 and the back turning plate. The combined use of hinge 18 and locating pin fully leverages the advantages of both, achieving a connection that is both flexible and stable.

[0044] Preferably, the two ends of the hip push rod and the back push rod are connected by an X-axis hinge 19 and a Y-axis hinge 20, respectively.

[0045] Specifically, such as Figure 4As shown, the two ends of the hip push rod and back push rod are connected by X-axis hinge 19 and Y-axis hinge 20 respectively, greatly enhancing the flexibility and adaptability of the bed assembly. X-axis hinge 19 allows relative rotation in the horizontal direction (or X-direction). When the hip push rod or back push rod is subjected to pushing or pulling forces in the X-direction, X-axis hinge 19 ensures that these forces are smoothly transmitted while allowing necessary rotation to accommodate the deformation requirements of the bed assembly. Y-axis hinge 20 allows relative rotation in the vertical direction (or Y-direction). When the hip push rod or back push rod undergoes displacement (such as lifting or lowering) in the Y-direction, Y-axis hinge 20 ensures that this displacement is smoothly achieved while maintaining the stability of the connection. The combined use of X-axis hinge 19 and Y-axis hinge 20 allows the hip push rod and back push rod to achieve flexible rotation and displacement in multiple directions, thereby meeting the needs of the bed assembly in various usage scenarios.

[0046] Preferably, the two ends of the leg push rod 9 and the foot push rod 10 are connected by Y-axis hinges 20.

[0047] Specifically, such as Figure 4 As shown, one end of the leg push rod 9 is connected to the bed frame 1 via a Y-axis hinge 20, and the other end is connected to the movable part of the lower leg plate 7 via another Y-axis hinge 20. This design allows the leg push rod 9 to flexibly push the lower leg plate 7 to perform actions such as raising, lowering, or tilting, to adapt to the leg needs of different users. One end of the foot push rod 10 is connected to a part of the lower leg plate 7 via a Y-axis hinge 20, and the other end is connected to the foot plate 8 via another Y-axis hinge 20. This design allows the foot push rod 10 to flexibly adjust the position and angle of the foot plate 8 to meet the user's needs for foot support and comfort. The use of the Y-axis hinges 20 allows the leg push rod 9 and the foot push rod 10 to achieve flexible rotation and displacement in the vertical direction, thereby meeting the various usage needs of the bed frame in the leg and foot areas.

[0048] Preferably, the standing aid board and the leg-lifting board are arranged symmetrically.

[0049] Specifically, the standing aid board and leg raise board are arranged symmetrically, meaning their designs are identical on both sides, considered mirror symmetry. This design helps ensure users receive the same support and comfort on either side of the bed. Furthermore, the standing aid board and leg raise board are positioned opposite each other on the bed frame, located at the top and bottom respectively. This arrangement helps ensure the bed frame remains structurally balanced and stable, further enhancing user comfort and experience. The symmetrical arrangement also helps maintain structural balance and stability, reducing safety hazards caused by instability or structural asymmetry.

[0050] Preferably, casters 21 are installed on the bottom of the foot plate 8 and the bottom of the bed frame 1.

[0051] Specifically, such as Figure 2 As shown, casters 21 are installed at the bottom of the footboard 8 and the bottom of the bed frame 1, allowing the entire bed assembly to move freely on the horizontal plane, thus enhancing the flexibility and comfort of the bed assembly.

[0052] Preferably, the bed device has a built-in remote control system.

[0053] Specifically, the bed frame incorporates a built-in remote control system, allowing users to operate various bed functions, such as raising, lowering, tilting, and turning over, without leaving the bed. For example, users can easily raise the back of the bed using the remote control system, transitioning from a lying to a sitting position, thus enhancing user convenience.
