[0044] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0045] Please refer to Figures 1 to 8As shown, an embodiment of this utility model provides an ultra-thin four-fold electric bed, including a rear support frame 600 and a front support frame 700, both of which are foldable.
[0046] The rear support frame 600 is fixedly connected to the top of one end of the rear buttock bed board 101, and the front support frame 700 is fixedly connected to the top of one end of the front buttock bed board 100. The front buttock bed board 100 and the rear buttock bed board 101 are hinged together by the first hinge member 102.
[0047] A legboard 200 is hinged to the side of the front buttocks bed board 100 away from the rear buttocks bed board 101, and a footboard 300 is hinged to the side of the legboard 200 away from the front buttocks bed board 100 via a second hinge 201.
[0048] A backrest board 400 is hinged to the side of the rear buttocks bed board 101 away from the front buttocks bed board 100, and a headboard 500 is hinged to the side of the backrest board 400 away from the rear buttocks bed board 101 via a third hinge 501.
[0049] The bottom of the rear buttocks bed board 101 is provided with a first driving member for driving the backrest bed board 400 to rotate upward;
[0050] The bottom of the front buttocks bed board 100 is provided with a second drive member for driving the leg bed board 200 to rotate upward;
[0051] When the bottom of the rear hip bed board 101 is folded towards the bottom of the front hip bed board 100, the rear support frame 600 and the front support frame 700 are in the same plane.
[0052] With the above configuration, the front buttocks bed board 100 and the leg bed board 200 form a first folding unit, and the footboard 300 is folded against the bottom of the leg bed board 200 via the second hinge 201; the rear buttocks bed board 101 and the backrest bed board 400 form a second folding unit, and the headboard 500 is attached to the surface of the backrest bed board 400 via the third hinge 501. The bottoms of the first folding unit and the bottoms of the second folding unit fold towards each other, ultimately making the rear support frame 600, the front support frame 700, and the drive component coplanar, thus minimizing the thickness. In this embodiment, the rear support frame 600 includes two rear support rods 601, which are respectively fixed to the bottom ends of the rear buttock bed board 101. A first mounting slot 603 is provided at the end of the rear support rod 601 away from the rear buttock bed board 101. A rear extension rod 602 is fixedly installed in the first mounting slot 603 by two sets of first locking bolts 604. A first support leg is installed at the bottom of the rear extension rod 602 by screws.
[0053] The rear support rod 601, as the core component supporting the rear buttocks bed board 101, forms an expandable support structure with the rear unfolding rod 602 through the first mounting slot 603. The first locking bolt 604 is used to fix the relative position of the two, locking them when unfolded to ensure support rigidity. When folding, one of the first locking bolts 604 is removed and the other first locking bolt 604 is loosened. Then, the rear unfolding rod 602 is rotated and folded towards the rear support rod 601 with the first locking bolt 604 as the axis.
[0054] In this embodiment, the first driving component includes a first electric push rod 800. One end of the first electric push rod 800 is fixed to the bottom of the rear buttock bed board 101. A first crossbeam 605 is fixedly connected between two rear support rods 601. The other end of the first electric push rod 800 is fixed to the first crossbeam 605. The first support rod 802 is hinged to the opposite sides of the first slide 801 of the first electric push rod 800. The first support rod 802 is hinged to the bottom of the backrest bed board 400 through a first linkage plate 803. A first roller 804 is rotatably mounted on the upper end of the first support rod 802. The first roller 804 makes rolling contact with the bottom of the backrest bed board 400.
[0055] The first electric push rod 800 drives the first slide 801 to move linearly. When the first slide 801 moves, it causes the first support rods 802 on both sides to swing, and the thrust is transmitted to the backrest bed board 400 through the first linkage plate 803. The first roller 804 reduces the frictional resistance between the support rods and the backrest bed board 400, while the first crossbeam 605 provides rigid support for the module, ensuring stable transmission of driving force and realizing precise angle adjustment of the backrest bed board. In use, when the first slide 801 moves away from the rear buttocks bed board 101, the backrest bed board 400 rotates upward about the hinge point with the rear buttocks bed board 101 as the rotation axis.
[0056] In this embodiment, the front support frame 700 includes two front support rods 701, which are respectively fixed to the bottom ends of the front buttock bed board 100. A second mounting slot 703 is provided at the end of each front support rod 701 away from the front buttock bed board 100. A front unfolding rod 702 is fixedly mounted in the second mounting slot 703 by two sets of second locking bolts 704. A second support leg is mounted to the bottom of the front unfolding rod 702 by screws. The front support rod 701 and the front unfolding rod 702 form an unfoldable support structure through the second mounting slot 703. The second locking bolts 704 lock the front unfolding rod 702 in the unfolded state. When folding, one of the second locking bolts 704 is removed, and the other second locking bolt 704 is loosened. Then, the front unfolding rod 702 is rotated and folded towards the front support rod 701 with the second locking bolt 704 as the axis.
[0057] In this embodiment, the second driving component includes a second electric push rod 900. One end of the second electric push rod 900 is fixed to the bottom of the front buttock bed board 100. A second crossbeam 705 is fixedly connected between two front support rods 701. The other end of the second electric push rod 900 is fixed to the second crossbeam 705. The two opposite sides of the second slide 901 of the second electric push rod 900 are hinged with second support rods 902. The second support rods 902 are hinged to the bottom of the leg bed board 200 through a second linkage plate 903. A second roller 904 is rotatably mounted on the upper end of the second support rod 902. The second roller 904 makes rolling contact with the bottom of the leg bed board 200.
[0058] In use, when the second slide 901 moves away from the front buttocks bed board 100, the leg bed board 200 rotates upward about the hinge point with the front buttocks bed board 100 as the rotation axis.
[0059] In this embodiment, the front unfolding rod 702 and the footboard 300 are hinged together by a first connecting plate 301. The first connecting plate 301 forms a kinematic linkage between the front unfolding rod 702 and the footboard 300. When the leg bed board 200 rotates upward, the footboard 300 flips downward through the second hinge 201.
[0060] In this embodiment, both the rear support frame 600 and the front support frame 700 are arranged in a figure-eight shape.
[0061] The figure-eight structure forms a stable support system through the outward expansion angle of the rear support rods 601 and the front support rods 701 on both sides, which can distribute the load of the bed to the ground and effectively prevent tipping.
[0062] In this embodiment, the rear support frame 600 and the front support frame 700, as well as the first electric push rod 800 and the second electric push rod 900, are staggered to ensure that the rear support frame 600 and the front support frame 700 are on the same plane when folded.
[0063] In this embodiment, in order to facilitate the smooth storage of the motors of the first electric push rod 800 and the second electric push rod 900 during folding, the motors of the first electric push rod 800 and the second electric push rod 900 are respectively housed in motor slots, which are respectively located at the bottom of the rear hip bed board 101 and the bottom of the front hip bed board 100.
[0064] Working principle: When folding, first remove the first leg and the second leg, and then separate the first connecting plate 301 from the front unfolding rod 702;
[0065] Remove one of the second locking bolts 704 and loosen the other second locking bolt 704. Then, rotate and fold the front unfolding rod 702 towards the front support rod 701 with the second locking bolt 704 as the axis. Remove one of the first locking bolts 604 and loosen the other first locking bolt 604. Then, rotate and fold the rear unfolding rod 602 towards the rear support rod 601 with the first locking bolt 604 as the axis.
[0066] Then, fold the bottom of the front buttocks bed board 100 towards the bottom of the rear buttocks bed board 101, so that the rear support frame 600 and the front support frame 700 are on the same plane. At this time, the rear support frame 600, the front support frame 700, the first electric push rod 800 and the second electric push rod 900 are sandwiched between the front buttocks bed board 100 and the rear buttocks bed board 101. Then, fold the footboard 300 down to the bottom of the leg bed board 200 and fold the headboard 500 to the top of the backrest bed board 400.
