DETAILED DESCRIPTION OF THE EMBODIMENTS

The implementations of the present disclosure will be explained in detail below in conjunction with the accompanying drawings and embodiments, so that an implementation process of how to solve the technical problems using the technical means and achieve the technical effects in the present disclosure can be fully understood and implemented.

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

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.

When the bottom of the rear hip bed plate 101 and the bottom of the front hip bed plate 100 are folded to each other, the rear supporting frame 600 and the front supporting frame 700 are located within the same plane.

Through the above arrangement, the front hip bed plate 100 and the leg bed plate 200 form a first folding unit, and the footboard 300 is backwards fitted and folded to a bottom of the leg bed plate 200 through the second hinge member 201. The rear hip bed plate 101 and the backrest bed plate 400 form a second folding unit, and the headboard 500 is forwards fitted to a surface of the backrest bed plate 400 through the third hinge member 501. A bottom of the first folding unit and a bottom of the second folding unit are folded to each other, thus ultimately making the rear supporting frame 600, the front supporting frame 700, and the driving members coplanar and implementing thickness minimization. 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 rear supporting rods 601 are used as core components of the rear hip bed plate 101, and form an expandable supporting structure together with the rear expansion rods 602 through the first mounting slots 603. The first locking bolts 604 are configured to fix relative positions of the first mounting slots 603 and the rear expansion rods 602 and implement locking during unfolding. 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. One end of the first linear actuator 800 is fixed at the bottom of the rear hip bed plate 101. A first cross beam 605 is fixedly connected between the two rear supporting rods 601. Another end of the first linear actuator 800 is fixed on the first cross beam 605. Two opposite side surfaces of a first sliding platform 801 of the first linear actuator 800 are hinged with first supporting rods 802. The first supporting rods 802 are hinged with a bottom of the backrest bed plate 400 through first linkage plates 803. Upper ends of the first supporting rods 802 are rotatably provided with first rollers 804. The first rollers 804 are in rolling contact with the bottom of the backrest bed plate 400.

The first linear actuator 800 drives the first sliding platform 801 to do linear motion. When moving, the first sliding platform 801 drives the first supporting rods 802 on the two sides to swing, so as to transfer a push force to the backrest bed plate 400 through the first linkage plates 803. The first rollers 804 reduce frictional resistance between the supporting rods and the backrest bed plate 400, and the first cross beam 605 provides rigid support for a module, to ensure stable transferring of a driving force and implement precise angle adjustment on the backrest bed plate. During use, when the first sliding platform 801 moves away from the rear hip bed plate 101, the backrest bed plate 400 rotates upwards by using a hinge point with the rear hip bed plate 101 as a rotation axis.

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 front supporting rods 701 form an expandable supporting structure together with the front expansion rods 702 through the second mounting slots 703. The second locking bolts 704 lock the front expansion rods 702 in an unfolded state. 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. One end of the second linear actuator 900 is fixed at the bottom of the front hip bed plate 100. A second cross beam 705 is fixedly connected between the two front supporting rods 701. Another end of the second linear actuator 900 is fixed on the second cross beam 705. Two opposite side surfaces of a second sliding platform 901 of the second linear actuator 900 are hinged with second supporting rods 902. The second supporting rods 902 are hinged with the bottom of the leg bed plate 200 through second linkage plates 903. Upper ends of the second supporting rods 902 are rotatably provided with second rollers 904. The second rollers 904 are in rolling contact with the bottom of the leg bed plate 200.

During use, when the second sliding platform 901 moves away from the front hip bed plate 100, the leg bed plate 200 rotates upwards by using a hinge point with the front hip bed plate 100 as a rotation axis.

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 forms a stable supporting system through outward expansion angles between the rear supporting rods 601 and the front supporting rods 701 on the two sides, so that a bed load can be dispersed to the ground, which effectively prevents rollover.

In this embodiment, the rear supporting frame 600 and the front supporting frame 700 are staggered, and the first linear actuator 800 and the second linear actuator 900 are staggered, thus ensuring that the rear supporting frame 600 and the front supporting frame 700 are located on the same plane during folding.

In this embodiment, in order to smoothly store motors of the first linear actuator 800 and the second linear actuator 900 during folding, the motors of the first linear actuator 800 and the second linear actuator 900 can be respectively accommodated in motor slots, and the motor slots are respectively provided in the bottom of the rear hip bed plate 101 and 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 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. 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, so that the rear supporting frame 600 and the front supporting frame 700 are located on the same plane. 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 a top of the backrest bed plate 400.
