DETAILED DESCRIPTION

[0025] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0026] like Figure 1-3 As shown, a folding lazy bed includes a main frame 1, a back frame 2 and a foot support frame 3. One side of the main frame 1 is movably connected to the back frame 2 through a hinge 5, and the other side of the main frame 1 is fixedly connected to the foot support frame 3. A motor 6 is installed at the bottom of the back frame 2, and the end of the motor shaft 61 of the motor 6 is installed on the main frame 1.

[0027] Specifically, the position at which the motor 6 is connected to the backrest frame 2 is higher than the position at which the end of the motor shaft 61 is connected to the main support 1. Therefore, when the folding lazy bed is laid flat, the motor 6 is tilted with the left side lower and the right side higher under the folding lazy bed, and the extension and retraction of the motor shaft 61 are also tilted extension and retraction; at the same time, since one end of the motor 6 is fixed to the backrest frame 2, and the end of the motor shaft 61 at the other end of the motor 6 is movably connected to the main support 1, when the motor shaft 61 is extended, an oblique downward force is generated, and the main support 1 and the backrest frame 2 are movably connected through the hinge 5, and the oblique downward force reacts to the backrest frame 2, and accordingly, the backrest frame 2 rotates counterclockwise around the main support 1; and when the motor shaft 61 retracts, the backrest frame 2 fixedly connected to the motor 6 can only rotate clockwise following the motor 6.

[0028] like Figure 1-2 As shown, the curved support rod 23 is bent toward the side away from the backrest frame 2, that is, the downwardly convex position of the middle portion of the curved support rod 23 is much lower than the second hanging ear 8 for mounting the motor shaft 61. Therefore, the motor shaft 61 does not interfere with the curved support rod. For the comfort of the user, the rotation angle of the backrest frame 2 is 0-90 degrees. Therefore, when the foldable lazy bed is laid flat, the extension and retraction of the motor shaft 61 does not affect the structure of the foldable lazy bed.

[0029] The motor 6 in the present invention cooperates with the hinge 5 to realize the rotation of the backrest frame 2, adapting to the human body's demand for angle changes of the folding lazy bed, and further improving the comfort of the folding lazy bed.

[0030] The main bracket 1, backrest frame 2, and foot support frame 3 have the same length and width dimensions, which is convenient for packaging and transportation after subsequent disassembly. In order to improve the comfort of the main bracket 1, backrest frame 2, and foot support frame, the main bracket 1, backrest frame 2, and foot support frame 3 can be covered with soft cushions.

[0031] The lower end of the main bracket 1 can be installed with a leg to support the entire folding lazy bed, making it convenient to unfold the folding lazy bed on flat ground.

[0032] The main bracket 1 includes a support rod 11 and a bracket connecting rod 12. The support rod 11 is used to strengthen the strength of the entire main bracket 1. The bracket connecting rod 12 includes a left connecting rod 121 and a right connecting rod 122. The left connecting rod 121 is provided with a plurality of threaded holes 1211. The right connecting rod 122 is provided with a second lifting ear 8 for installing the motor shaft 61. The second lifting ear 8 is provided with an installation shaft 7 connected to the motor shaft 61, and the installation shaft 7 is clearance-fitted in the second lifting ear 131.

[0033] The backrest frame 2 includes a backrest connecting rod 21 symmetrically arranged front and back, a longitudinal rod 22 between the backrest connecting rods 21, and a bent support rod 23. The longitudinal rod 22 is provided with a first hanging ear 4 for mounting the motor 6. The bent support rod 23 is bent toward the side away from the backrest frame 2. The backrest connecting rod 21 is used to support the longitudinal rod 22 and limit its position. At the same time, it can also enhance the strength of the entire backrest frame 2.

[0034] The height of the longitudinal rod 22 is higher than that of the right connecting rod 122 , and the motor 6 is arranged obliquely between the main bracket 1 and the backrest frame 2 , so that the motor rod 6 can be tilted and extended to drive the rotation of the backrest frame 2 .

[0035] The foot support frame 3 includes a foot connecting rod 31, a short rod 32 at the upper end of the foot connecting rod 31, and a mounting rod 33. The mounting rod 33 is provided with a plurality of first through holes 331, and the first through holes 331 are adapted to the threaded holes 1211 on the left connecting rod 121. The connecting rod 31 is used to reinforce the foot support frame 3, and the short rod 32 at its upper end further supports it in order to ensure the curvature of the upper end surface of the foot support frame 3.

[0036] Specifically, front and rear symmetrical hinges 5 are installed on the main bracket 1 and the backrest frame 2; the first lifting ear 4 is welded to the middle of the longitudinal rod 22, and the tail of the motor 6 is fixedly connected to the first lifting ear 4 by screws. Since the motor 6 is arranged obliquely between the main bracket 1 and the backrest frame 2, the tail of the motor 6 is not completely fitted with the first lifting ear 4, and a certain gap is left to facilitate adjustment of the motor 6 according to actual conditions when in use; the motor shaft 61 of the motor 6 is movably connected to the second lifting ear 8 through the mounting shaft 7, and a through hole is provided at the end of the motor shaft 61, and the mounting shaft 7 passes through the through hole, and the mounting shaft 7 is gap-matched with the through hole at the end of the motor shaft 61, and the two ends of the mounting shaft 7 are located in the through hole of the second lifting ear 8; the installation of the hinge 5 and the motor 6 realizes the movable connection between the main bracket 1 and the backrest frame 2.

[0037] Furthermore, the main bracket 1 and the foot support frame 3 are connected by installing screws in the first through hole 331 and the thread 1211.

[0038] The utility model can realize the laying and folding of the folding lazy bed only by installing and disassembling the motor 6, the dumpling part 5 and the screws. The folding lazy bed has a simple structure and is convenient for large-scale use.

[0039] Reinforcement ribs 9 are arranged on the upper end surfaces of the main bracket 1, the backrest frame 2, and the foot support frame 3 facing the human body. Several cross-reinforcement ribs 9 in a mesh shape support the human body and also increase the strength of the backrest frame 2; the hinges 5 are located on both sides of the main bracket 1, which can synchronously realize the rotation of the backrest frame 2, and at the same time, do not interfere with the human body lying on the folding lazy bed.

[0040] like Figure 2-3 As shown, the side surfaces of the backrest frame 2 and the foot support frame 3 are triangular, and the side surface of the main frame 1 is rectangular. After the main frame 1, the backrest frame 2, and the foot support frame 3 are folded, the triangular backrest frame 2 and the foot support frame 3 can be folded into a rectangle, which reduces the space occupied by the backrest frame 2 and the foot support frame 3 and facilitates the transportation of the foldable lazy bed.

[0041] Specifically, knock out the mounting shaft 7 from the through hole of the second lifting ear 8 and the through hole at the end of the motor shaft 61, and then loosen the screws connecting the motor 6 to the first lifting ear 4; accordingly, remove the screws in the first through hole 331 and the threaded hole 1211; further, the main bracket 1 and the backrest frame 2 can be folded into one piece through the hinge 5, and then the disassembled foot support frame 3 is stacked on the backrest frame 2 to form a rectangular structure. The whole process only involves the disassembly of the motor 6 and the screws. The disassembly and installation of the folding lazy bed is very fast and convenient, which is beneficial for daily use. At the same time, the disassembled main bracket 1, backrest frame 2, and foot support frame 3 form a rectangular structure, which is also convenient for actual folding and transportation.

[0042] The upper end surface of the main bracket 1 is in the shape of an arc with a concave middle part and convex on both sides; the upper end surface of the backrest frame 2 is in the shape of an arc with a concave side toward the main bracket 1 and a convex side on the other side; the upper end surface of the foot support frame 3 is in the shape of an arc with a convex side toward the main bracket 1 and a concave side on the other side; the upper end surface of the folding lazy bed forms a small S-shape, which fits the curvature of the human body better than a flat upper end surface, and can improve the comfort of the folding lazy bed.

[0043] Although this article uses the figure marks in the figures more frequently: main bracket 1, backrest bracket 2, foot support bracket 3, first lifting ear 4, hinge 5, motor 6, mounting shaft 7, second lifting ear 8, reinforcing rib 9, support rod 11, bracket connecting rod 12, backrest connecting rod 21, longitudinal rod 22, curved support rod 23, foot connecting rod 31, short rod 32, mounting rod 33, motor shaft 61, left connecting rod 121, right connecting rod 122, first through hole 331, threaded hole 1211 and other terms, it does not exclude the possibility of using other terms; these terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
