[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 buttock bed board 100 is provided with a second drive member for driving the leg bed board 200 to rotate upward;
[0051] The front buttocks bed board 100 and the leg bed board 200 form a first folding unit, and the rear buttocks bed board 101 and the backrest bed board 400 form a second folding unit. The second folding unit can be folded to the bottom of the first folding unit. The headboard 500 can be folded to the top of the backrest bed board 400, and the footboard 300 can be folded to the bottom of the leg bed board 200.
[0052] The front buttocks bed board 100 and the rear buttocks bed board 101 can rotate relative to each other through the first hinge 102, so that when folding, the front buttocks bed board 100 can fold against the rear buttocks bed board 101. The first drive unit drives the backrest bed board 400 to rotate around the rear buttocks bed board 101, and the second drive unit drives the leg bed board 200 to rotate around the front buttocks bed board 100, thereby realizing the adjustment of the bed angle. When folding, the second folding unit folds to the bottom of the first folding unit, the headboard 500 is folded and attached to the top of the backrest bed board 400 through the third hinge 501, and the footboard 300 is folded and attached to the bottom of the leg bed board 200 through the second hinge 201, completing the four-fold storage.
[0053] 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.
[0054] Two rear support rods 601 provide bottom support for the rear hip bed board 101; the rear unfolding rod 602 is fixed to the rear support rod 601 through the first mounting slot 603 and the first locking bolt 604, and the first support leg at the bottom is in direct contact with the ground, which enhances the stability of the rear support frame 600. When folding, remove one of the first locking bolts 604 and loosen the other first locking bolt 604, and then rotate the rear unfolding rod 602 around the first locking bolt 604 as the axis to fold it towards the rear support rod 601.
[0055] In this embodiment, the first driving component includes a first electric push rod 800. The cylinder of the first electric push rod 800 is fixed to the bottom of the rear buttock bed board 101. A first crossbar 801 is rotatably connected between two rear support rods 601. A first push rod 803 is fixedly connected to both ends of the first crossbar 801. A first roller 804 is rotatably connected to the upper end of the first push rod 803. The first roller 804 rolls in contact with the bottom of the backrest bed board 400. A first connecting seat 802 is fixedly connected to the bottom of one end of the first crossbar 801. The piston rod end of the first electric push rod 800 is hinged to the lower end of the first connecting seat 802.
[0056] When the piston rod of the first electric push rod 800 extends or retracts, it drives the first crossbar 801 to rotate through the first connecting seat 802. When the first crossbar 801 rotates, the first push rods 803 at both ends lift up synchronously, and the first roller 804 at its top rolls along the bottom of the backrest bed board 400 and pushes it to rotate upward, thereby realizing the adjustment of the backrest angle. The contact of the rollers reduces the frictional resistance during the driving process.
[0057] 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 the front support rod 701 away from the front buttock bed board 100. A front unfolding rod 702 is fixedly installed in the second mounting slot 703 by two sets of second locking bolts 704. A second support leg is installed at the bottom of the front unfolding rod 702 by screws.
[0058] Two front support rods 701 support the front buttock bed board 100, which together with the rear support frame 600 form the basic support structure of the bed. The front unfolding rod 702 is fixed by the second mounting slot 703 and the second locking bolt 704. The second support leg is in contact with the ground and works with the first support leg to ensure the overall stability of the bed. When folding, remove one of the second locking bolts 704 and loosen the other second locking bolt 704. Then, rotate the front unfolding rod 702 around the second locking bolt 704 as the axis to fold it forward to the support rod 701.
[0059] In this embodiment, the second driving component includes a second electric push rod 900. The cylinder of the second electric push rod 900 is fixed to the bottom of the front buttock bed board 100. A second crossbar 901 is rotatably connected between two front support rods 701. A second push rod 903 is fixedly connected to both ends of the second crossbar 901. A second roller 904 is rotatably connected to the upper end of the second push rod 903. The second roller 904 rolls in contact with the bottom of the leg bed board 200. A second connecting seat 902 is fixedly connected to the bottom of one end of the second crossbar 901. The piston rod end of the second electric push rod 900 is hinged to the lower end of the second connecting seat 902.
[0060] When the piston rod of the second electric push rod 900 extends or retracts, it drives the second crossbar 901 to rotate through the second connecting seat 902; the rotation of the second crossbar 901 causes the second push rod 903 to lift up, and the second roller 904 rolls along the bottom of the leg bed board 200 and pushes it to rotate upward, thereby realizing the adjustment of the leg angle.
[0061] In this embodiment, the front unfolding rod 702 and the bed tail plate 300 are hinged together by the first connecting plate 301.
[0062] 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 via the second hinge 201.
[0063] In this embodiment, both the rear support frame 600 and the front support frame 700 are arranged in a figure-eight shape.
[0064] The figure-eight structure increases the lateral span of the supporting base, lowers the center of gravity of the bed, improves the anti-tipping ability of the bed in the unfolded state, and at the same time leaves enough space for the rotation of the folding unit.
[0065] In this embodiment, the rear support frame 600 and the front support frame 700 are staggered.
[0066] The staggered arrangement of the rear support frame 600 and the front support frame 700 can prevent mechanical interference between the front and rear support structures when the second folding unit is folded down to the bottom of the first folding unit during folding, ensuring a smooth folding process and reducing the overall volume after folding.
[0067] In this embodiment, in order to smoothly accommodate the motors of the first electric push rod 800 and the second electric push rod 900 when folded, a first motor slot for accommodating the motor of the first electric push rod 800 is reserved at the bottom of the rear hip bed board 101, and a second motor slot for accommodating the motor of the second electric push rod 900 is reserved at the bottom of the front hip bed board 100.
[0068] 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;
[0069] 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.
[0070] 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 around the first locking bolt 604 as the axis to the rear support rod 601.
[0071] Then, fold the bottom of the front buttocks bed board 100 towards the bottom of the rear buttocks bed board 101. 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.
