[0038] A three-fold bed that is convenient for transportation and assembly, characterized in that it includes a back bed body 1, a hip bed body 2, a leg bed body 3, and a support foot 6.

[0039] The back bed body 1 includes a back bottom frame 12 and a back bed board 11 located above the back bottom frame 12. The tail ends of the back bed board 11 and the back bottom frame 12 are both rotatably connected to the head position of the hip bed body 2. After rotation, the back bed board 11 and the back bottom frame 12 can be respectively stacked on the front and back surfaces of the hip bed body 2. The leg bed body 3 includes a leg bottom frame 32 and a leg bed board 31 arranged above the leg bottom frame 32. The head of the leg bottom frame 32 is rotatably connected to the tail position of the hip bed body 2. After rotation, the leg bottom frame 32 drives the leg bed board 31 to be able to be stacked on the back surface of the hip bed body 2. There are multiple support feet 6, and each upper end of the support feet 6 has a connecting bolt 62. Connecting holes 7 for screwing the connecting bolts 62 are provided at the bottoms of the back bottom frame 12, the hip bed body 2, and the leg bottom frame 32.

[0040] In the hip bed body 2, it includes a hip bed board 22 and a connecting seat 21. There are four connecting seats 21, which are divided into two groups and are respectively fixed to the bottom surface of the head and the bottom surface of the tail of the hip bed board 22 by bolts for the back bottom frame 12 and the leg bottom frame 32 to be rotatably connected. The connecting hole 7 for screwing the connecting bolt 62 on the hip bed body 2 is opened on the bottom wall of the connecting seat 21, so that the support feet 6 support the middle position of the three-fold bed in the unfolded state.

[0041] In the back bed body 1, the tail of the back bed board 11 is connected to the head position of the hip bed board 22 through a hinge structure, so that the back bed board 11 can be flipped from the horizontally unfolded state to the stacked state of being stacked on the front of the hip bed board 22. The tail of the back bottom frame 12 is connected to the two connecting seats 21 corresponding to the head of the hip bed board 22 through a pin shaft, so that the back bottom frame 12 can be flipped from the horizontally unfolded state to the stacked state of being stacked on the back of the hip bed board 22.

[0042] The back bottom frame 12 is a U-shaped frame, including two side rods 121 extending along the front-back direction of the three-fold bed in the unfolded state and a cross bar 122 located between the heads of the two side rods 121. The tail positions of the two side rods are rotatably connected to the connecting seats 21 corresponding to the head of the hip bed body 2 through a pin shaft.

[0043] The connecting hole 7 for screwing the connecting bolt 62 on the back bottom frame 12 is opened on the bottom surfaces on both sides of the head of the back bottom frame 12, so that the support feet 6 can be assembled when the back bottom frame 12 is in the unfolded state, and the support feet 6 support the head position of the three-fold bed in the unfolded state.

[0044] A first lifting mechanism 4 for lifting the head of the back bed board 11 is provided between the back bottom frame 12 and the back bed board 11. The first lifting mechanism 4 includes a first push rod motor 43, a rotating shaft 41, and a lifting arm 42;

[0045] There are two lifting arms 42, and the two lifting arms 42 are respectively installed on the inner walls of the two side rods 121. That is, one end of each lifting arm 42, i.e., the first end, is rotatably connected to the U-shaped seat on the inner wall of the side rod 121 through a pin shaft, and is close to the tail position of the side rod 121. The other end, i.e., the second end, of the lifting arm 42 is connected to a roller 421, and abuts against the plate body 111 on the back of the back bed board 11. The two ends of the rotating shaft 41 are respectively connected to the positions of the two lifting arms 42 close to the first end. The motor seat of the first push rod motor 43 is connected to the cross bar 122 through a hinge seat, and the piston rod of the first push rod motor 43 is connected to the rotating shaft 41 through a hinge seat, and the second end of the lifting arm 42 is driven to lift or descend through the rotating shaft 41, thereby pushing the head of the back bed board 11 to lift or descend.

[0046] The structure of the leg frame 32 is the same as that of the back frame 12, both of which are U-shaped structures. The U-shaped opening of the leg frame 32 faces the hip bed body 2, and the heads of the two side rods in the leg frame 32 are connected to the connecting seat 21 at the corresponding tail of the hip bed board 22 through a pin shaft.

[0047] The width of the back frame 12 is smaller than the width of the leg frame 32, which refers to the left-right dimension of the back frame 12 and the leg frame 32 of the tri-fold bed. In this structure, when the tri-fold bed is in the folded state, the back frame 12 is flipped to the inside of the leg frame 32, so that the back frame 12 and the leg frame 32 have an overlapping portion in the horizontal viewing angle, so as to reduce the thickness of the tri-fold bed in the folded state as much as possible, which is convenient for packaging and transportation.

[0048] The head position of the back bed board 11 is connected to a back extension board 13 through a hinge structure. When the tri-fold bed is in the unfolded state, the head position of the back extension board 13 extends to the outside of the back base frame 12 to increase the length of the entire back bed board 11; the tail position of the back extension board 13 is supported on the back base frame 12, and is connected and fixed to the head position of the back bed board 11 by bolts 8. When the tri-fold bed is in the folded state, the back extension board 13 can be turned over and pressed against the side position of the tri-fold bed. Figure 2 As shown, the size of the tri-fold bed in the folded state can be reduced while ensuring the effective length of the tri-fold bed as a whole.

[0049] The leg bed board 31 includes a front bed board 311, a rear bed board 312 and a support rod 33. The head of the front bed board 311 is connected to the head position of the leg chassis 32 through a pin shaft, and the tail of the front bed board 311 is rotatably connected to the head of the rear bed board 312 through a pin shaft. One end of the support rod 33 is rotatably connected to the leg chassis 32, and the other end is rotatably connected to the tail position of the rear bed board 312, so that the tail of the front bed board 311 and the head of the rear bed board 312 can be lifted upward. A second lifting mechanism 5 for lifting the leg bed board 31 is provided between the leg chassis 32 and the rear bed board 312.

[0050] The second lifting mechanism 5 is a second push rod motor. One end of the second push rod motor, i.e., the motor base, is connected to the head position of the rear bed board 312 through a hinge seat, and the other end of the piston rod is connected to the cross bar of the leg chassis 32 through a hinge seat. When the second push rod motor extends, it can drive the side where the front bed board 311 and the rear bed board 312 are connected to lift upward, improving the comfort of the user.

[0051] The support foot 6 includes a support tube 61 and a mounting plate 63 welded to the top of the support tube 61. There is a connection hole on the mounting plate 63, and the connecting bolt 62 is welded and fixed to the mounting plate in an inverted state. When assembling the support foot 6, directly align the connecting bolt 62 with the connection hole, rotate the support tube 61, and cooperate with the nut or the internal thread in the connection hole to screw the connecting bolt 62 into the connection hole, realizing the fixation of the support foot 6 on the three-fold bed, which has the characteristics of simple operation.

[0052] In this embodiment, the head of each component is the end corresponding to the head of the bed, the tail is the end corresponding to the tail of the bed, and the front-back direction is the direction from the head of the bed to the tail of the bed.

[0053] The leg bed board 31, the hip bed board 22, the front bed board 311 and the rear bed board 312 are all composed of a surrounding frame, support rods 33 arranged in the surrounding frame and steel wires arranged in the surrounding frame.

[0054] During packaging and transportation, from the unfolded position to the stacked position, the back bed board is flipped 180 degrees and stacked on the front of the hip bed board 22, the back chassis is flipped 180 degrees and stacked on the back of the hip bed board 22, then the leg chassis 32 together with the leg bed board is flipped 180 degrees and stacked on the back of the hip bed board 22, and finally the back extension board 13 is flipped 90 degrees downward and abutted against the side position of the three-fold bed. At the same time, the tail of the connecting seat 21 at the corresponding tail position of the hip bed board 22 enters the opening 131 of the back extension board 13 as Figure 2As shown in the figure, when the back extension board 13 is not unfolded, the tail of the connecting seat 21 is located in the opening 131 of the back extension board 13, which can avoid the problem that the back bed board 11 accidentally flips upward. It has the characteristics of stable superposition and small volume after superposition, which is convenient for packaging. Secondly, when the triple-fold bed is in the superposed state, the back bed board 11, the leg bed board 31 and the backrest extension board are relatively flat and located on the outermost side, wrapping the back bottom frame 12, the hip bed body 2, the leg bottom frame 32, the first lifting mechanism 4 and the second lifting mechanism 5 inside, which can make the overall shape of the triple-fold bed in the superposed state square, further facilitating packaging and transportation.
