Referring to FIG. 1 to FIG. 8, an embodiment of the present disclosure provides a four-fold electric bed, including a rear supporting frame 600 and a front supporting frame 700.

A top of one end of the rear supporting frame 600 is fixedly connected with a rear hip bed plate 101. A top of one end of the front supporting frame 700 is fixedly connected with a front hip bed plate 100. The front hip bed plate 100 is hinged with the rear hip bed plate 101 through a first hinge member 102.

One side of the front hip bed plate 100 that is away from the rear hip bed plate 101 is hinged with a leg bed plate 200. One side of the leg bed plate 200 that is away from the front hip bed plate 100 is hinged with a footboard 300 through a second hinge member 201.

One side of the rear hip bed plate 101 that is away from the front hip bed plate 100 is hinged with a backrest bed plate 400. One side of the backrest bed plate 400 that is away from the rear hip bed plate 101 is hinged with a headboard 500 through a third hinge member 501.

A first driving member for driving the backrest bed plate 400 to rotate upwards is arranged at a bottom of the rear hip bed plate 101.

A second driving member for driving the leg bed plate 200 to rotate upwards is arranged at a bottom of the front hip bed plate 100.

The front hip bed plate 100 and the leg bed plate 200 form a first folding unit, and the rear hip bed plate 101 and the backrest bed plate 400 form a second folding unit. The second folding unit can be folded to a bottom of the first folding unit. The headboard 500 can be folded to a top of the backrest bed plate 400. The footboard 300 can be folded to a bottom of the leg bed plate 200.

Relative rotation between the front hip bed plate 100 and the rear hip bed plate 101 is implemented through the first hinge member 102, so that during folding, the front hip bed plate 100 can be folded against the rear hip bed plate 101. The first driving member drives the backrest bed plate 400 to rotate around the rear hip bed plate 101, and the second driving member drives the leg bed plate 200 to rotate around the front hip bed plate 100, to implement angle adjustment on a bed body. During folding, the second folding unit is folded to the bottom of the first folding unit. The headboard 500 is folded and fitted to the top of the backrest bed plate 400 through the third hinge member 501. The footboard 300 is folded and fitted to the bottom of the leg bed plate 200 through the second hinge member 201, thus completing four-fold storage.

In this embodiment, the rear supporting frame 600 includes two rear supporting rods 601. The two rear supporting rods 601 are respectively fixed at two ends of the bottom of the rear hip bed plate 101. A first mounting slot 603 is provided in one end of each rear supporting rod 601 that is away from the rear hip bed plate 101. Rear expansion rods 602 are fixedly mounted in the first mounting slots 603 through two groups of first locking bolts 604. First supporting legs are mounted at bottoms of the rear expansion rods 602 through screws.

The two rear supporting rods 601 provide bottom support for the rear hip bed plate 101. The rear expansion rods 602 are fixed with the rear supporting rods 601 through the first mounting slots 603 and the first locking bolts 604. The first supporting legs at the bottom are in direct contact with the ground to improve stability of the rear supporting frame 600. During folding, one first locking bolt 604 is removed, and the other first locking bolt 604 is loosened. Then, the rear expansion rods 602 are rotatably folded towards the rear supporting rods 601 by using the first locking bolts 604 as axes.

In this embodiment, the first driving member includes a first linear actuator 800. A cylinder of the first linear actuator 800 is fixed at the bottom of the rear hip bed plate 101. A first cross bar 801 is rotatably connected between the two rear supporting rods 601. Two ends of the first cross bar 801 are fixedly connected with first push rods 803. Upper ends of the first push rods 803 are rotatably connected with first rollers 804. The first rollers 804 are in rolling contact with a bottom of the backrest bed plate 400. A bottom of one end of the first cross bar 801 is fixedly connected with a first connection base 802. An end portion of a piston rod of the first linear actuator 800 is hinged with a lower end of the first connection base 802.

When the piston rod of the first linear actuator 800 extends and retracts, the first cross bar 801 is driven to rotate by the first connection base 802. When the first cross bar 801 rotates. The first push rods 803 at the two ends are synchronously lifted up, and the first rollers 804 at the tops of the first push rods 803 roll along the bottom of the backrest bed plate 400 and push the backrest bed plate 400 to rotate upwards, thus implementing backrest angle adjustment. Roller contact reduces frictional resistance in a driving process.

In this embodiment, the front supporting frame 700 includes two front supporting rods 701. The two front supporting rods 701 are respectively fixed at two ends of the bottom of the front hip bed plate 100. A second mounting slot 703 is provided in one end of each front supporting rod 701 that is away from the front hip bed plate 100. Front expansion rods 702 are fixedly mounted in the second mounting slots 703 through two groups of second locking bolts 704. Second supporting legs are mounted at bottoms of the front expansion rods 702 through screws.

The two front supporting rods 701 support the front hip bed plate 100 and form a basic supporting structure of the bed body together with the rear supporting frame 600. The front expansion rods 702 are fixed through the second mounting slots 703 and the second locking bolts 704, and the second supporting legs are in contact with the ground and cooperate with the first supporting legs to ensure overall steadiness of the bed body. During folding, one second locking bolt 704 is removed, and the other second locking bolt 704 is loosened. Then, the front expansion rods 702 are rotatably folded towards the front supporting rods 701 by using the second locking bolts 704 as axes.

In this embodiment, the second driving member includes a second linear actuator 900. A cylinder of the second linear actuator 900 is fixed at the bottom of the front hip bed plate 100. A second cross bar 901 is rotatably connected between the two front supporting rods 701. Two ends of the second cross bar 901 are fixedly connected with second push rods 903. Upper ends of the second push rods 903 are rotatably connected with second rollers 904. The second rollers 904 are in rolling contact with a bottom of the leg bed plate 200. A bottom of one end of the second cross bar 901 is fixedly connected with a second connection base 902. An end portion of a piston rod of the second linear actuator 900 is hinged with a lower end of the second connection base 902.

When the piston rod of the second linear actuator 900 extends and retracts, the second cross bar 901 is driven to rotate by the second connection base 902. The rotation of the second cross bar 901 causes the second push rods 903 to be lifted up, and the second rollers 904 roll along the bottom of the leg bed plate 200 and push the leg bed plate 200 to rotate upwards, thus implementing leg angle adjustment.

In this embodiment, the front expansion rods 702 are hinged with the footboard 300 through first connection plates 301.

The first connection plates 301 form a motion linkage relationship between the front expansion rods 702 and the footboard 300. When the leg bed plate 200 rotates upwards, the footboard 300 flips downwards through the second hinge member 201.

In this embodiment, both the rear supporting frame 600 and the front supporting frame 700 are arranged in a splayed manner.

A splayed structure can increase a transverse span of a supporting bottom surface, lower a center of gravity of the bed body, improve an anti-tilting ability of the bed body in an unfolded state, and reserve an enough space for rotation of the folding units.

In this embodiment, the rear supporting frame 600 and the front supporting frame 700 are staggered.

The staggered layout of the rear supporting frame 600 and the front supporting frame 700 can avoid mechanical interference between the front supporting structure and the rear supporting structure when the second folding unit is downwards folded to the bottom of the first folding unit during folding, thus ensuring a smooth folding process and reducing an overall volume after folding.

In this embodiment, in order to smoothly store a motor of the first linear actuator 800 and a motor of the second linear actuator 900 during folding, a first motor slot for accommodating the motor of the first linear actuator 800 is reserved in the bottom of the rear hip bed plate 101; and meanwhile, a second motor slot for accommodating the motor of the second linear actuator 900 is reserved in the bottom of the front hip bed plate 100.

Working principle: During folding, the first supporting legs and the second supporting legs are first removed, and the first connection plates 301 and the front expansion rods 702 are then separated.

One second locking bolt 704 is removed, and the other second locking bolt 704 is loosened. Then, the front expansion rods 702 are rotatably folded towards the front supporting rods 701 by using the second locking bolts 704 as the axes.

One first locking bolt 604 is removed, and the other first locking bolt 604 is loosened. Then, the rear expansion rods 602 are rotatably folded towards the rear supporting rods 601 by using the first locking bolts 604 as the axes.

Then, the bottom of the front hip bed plate 100 is folded to the bottom of the rear hip bed plate 101. In this case, the rear supporting frame 600, the front supporting frame 700, the first linear actuator 800, and the second linear actuator 900 are sandwiched between the front hip bed plate 100 and the rear hip bed plate 101. Then, the footboard 300 is downwards folded to the bottom of the leg bed plate 200, and the headboard 500 is folded to the top of the backrest bed plate 400.
