[0038] An adjusting steel plate 4, one end of the adjusting steel plate 4 is connected to the adjustable backrest 3, the other end of the adjusting steel plate 4 is inserted into the housing 15 and is rotatably connected to the housing 15;

[0039] And an angle adjusting mechanism, the angle adjusting mechanism is respectively connected to the lying sofa body 1, the adjustable backrest 3, the adjusting steel plate 4 and the housing 15. Among them, the angle adjusting mechanism includes a rotation driving component and a limit transmission component;

[0040] The rotation driving component is respectively connected to the lying sofa body 1 and the adjustable backrest 3, and the limit transmission component is respectively connected to the adjusting steel plate 4 and the housing 15.

[0041] During the use of the lying sofa body 1, by manually driving the rotation driving component to act, the adjusting steel plate 4 can be driven to rotate around the housing 15. For example, when the lying sofa body 1 is in a normal state or a lying state, the rotation path of the adjusting steel plate 4 can be rotation circle one 6 or rotation circle two 11. Among them, the rotation paths of rotation circle one 6 and rotation circle two 11 are the same. By changing the position state of the adjustable backrest 3 through the lying sofa body 1, the comfort can be improved. Through multi-angle adjustment and the use of memory foam materials, a personalized comfortable experience is provided for users; the practicability is enhanced to meet the rest needs in different scenarios, such as reading, watching movies and taking a nap, etc.; the operation is simple, with a simple design and operation method, enabling users of all ages to easily get started; space is saved, with an optimized structural design, and no excessive additional space is occupied during the adjustment process; it is safe and reliable, using high-quality materials and a stable adjustment mechanism to ensure safety during use.

[0042] In an embodiment of the present utility model, please refer to Figures 1-10 , it further includes: pillow covers 5, the number of the pillow covers 5 is multiple, and the multiple pillow covers 5 are evenly distributed on the adjustable backrest 3;

[0043] And an adjusting base 9, the adjusting base 9 is located on the lying sofa body 1 and is detachably connected to the adjustable backrest 3.

[0044] The housing 15 is composed of two parts of the shell, and the two parts of the shell are connected by flat head screws 14;

[0045] In addition, the trajectory of the adjustable backrest 3 moving from the normal state to the lying state is the angle adjustment arc 10, and the included angle corresponding to the angle adjustment arc 10 is 35°.

[0046] Please refer to Figures 1-10 , the rotation drive assembly includes:

[0047] A backrest steel pipe 7, one end of the backrest steel pipe 7 is fixedly connected to the adjustable backrest 3;

[0048] A hydraulic rod 2, the hydraulic rod 2 is located inside the lying sofa body 1, and one end of the hydraulic rod 2 is rotatably connected to the bottom end of the backrest steel pipe 7;

[0049] And a connecting seat 8, the connecting seat 8 is fixedly connected to the lying sofa body 1 and is rotatably connected to the output end of the hydraulic rod 2.

[0050] The limit drive assembly includes:

[0051] A chute 13, the chute 13 is located inside the housing 15, and a pin 12 is rotatably installed in the chute 13, and the pin 12 is fixedly connected to the end of the adjusting steel plate 4;

[0052] And a steel plate surface one 16 and a steel plate surface two 17, both the steel plate surface one 16 and the steel plate surface two 17 are located inside the housing 15. When the lying sofa body 1 is in the normal state, the adjusting steel plate 4 abuts against the steel plate surface two 17. When the lying sofa body 1 is in the lying state, the adjusting steel plate 4 abuts against the steel plate surface one 16.

[0053] The lying sofa body 1 of the present application is divided into four major parts: a basic frame, a seat cushion, an adjustable backrest 3 and an angle adjustment mechanism. The basic frame is made of a strong and durable metal material, and the seat cushion and the adjustable backrest 3 are covered with a memory foam layer and a breathable fabric. The hydraulic rod 2 is hidden at the bottom of the lying sofa body 1. The user only needs to gently pull the operating rod on the side to adjust the angle of the sofa. On this basis, an optimization and upgrade has been carried out to adjust the rotation point of the entire backrest, an aluminum alloy fixed backrest has been installed, and the rotation trajectory has been adjusted to be more ergonomic and fit the human waist trajectory. In addition, the aluminum alloy fixing part also integrates a limiting function, and a plastic cover is installed for beautification to achieve the integration of beauty and practicality;

[0054] As shown in the figure, the through holes on the adjusting steel plate 4 are connected to the adjustable backrest 3 by screws. The adjusting steel plate 4 and the pin 12 are welded together as a whole. The pin 12 can be placed in the chute 13 of the aluminum alloy fixing part, which can realize a split design, and is fixed and limited by flat head screws 14 so that the pin 12 cannot be taken out.

[0055] In addition, during the rotation of the adjusting steel plate 4, it will drive the pillow package 5 to complete the revolution around the first rotation circle 6 to complete the lying-down motion, achieving ergonomic design. Moreover, the backrest steel pipe 7 extends all the way to the lower end and is connected to the hydraulic rod 2. The connection between the hydraulic rod 2 and the connecting seat 8 completes the linkage of the motion, and the hydraulic rod 2 provides power for reset. At the same time, the surface of the adjusting base 9 just forms an occlusion to hide the mechanism inside. And the design of the adjusting base 9 allows for no occlusion in the lying-down state at the lowest point. The lying-down angle from the normal state to the lying-down state is 35°. It lies down around the second rotation circle 11. At this time, the air rod contracts to complete energy storage, and pressing the release button can return it to the upright position.

[0056] It should be noted that in the present utility model, unless otherwise clearly specified and defined, terms such as "sliding", "rotating", "fixing", "being provided with", etc. should be understood in a broad sense. For example, it can be a welded connection, a bolt connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0057] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
