[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figures 1-3 This utility model provides an embodiment of a comfortable sofa base assembly, including a base body 1. A first support plate 2 is slidably connected inside the base body 1. A motor 3 is fixedly connected to the upper surface of the first support plate 2. A threaded rod 4 is connected to the output end of the motor 3. A first support rod 5 is threadedly connected to the outer wall of the threaded rod 4. The outer wall of the threaded rod 4 is rotatably connected to the inside of the first support plate 2. A second support rod 6 is rotatably connected to the inside of the first support rod 5. A second support plate 7 is rotatably connected to the outer wall of the second support rod 6. The upper surface of the second support plate 7 is fixedly connected to the inside of the base body 1. A sliding component is provided on the lower surface of the first support rod 5. The sliding component is used to assist the sofa in raising and lowering.

[0025] Specifically, the output end of the motor 3 is used to drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, it can drive the interior of the first support rod 5 to rotate the outer wall of the second support rod 6. When the interior of the first support rod 5 drives the outer wall of the second support rod 6 to rotate, it can drive the outer wall of the second support rod 6 to rotate inside the second support plate 7.

[0026] Reference Figures 2-4 The sliding assembly includes a sliding plate 8, the upper surface of which is fixedly connected to the lower surface of the first support rod 5, a slide rail 9 is slidably connected inside the sliding plate 8, a baffle 10 is fixedly connected to the outer wall of the base body 1, and the lower surface of the slide rail 9 is fixedly connected to the upper surface of the first support plate 2.

[0027] Specifically, when the first support rod 5 slides, it can drive the inside of the sliding plate 8 to slide inside the slide rail 9. When the inside of the sliding plate 8 slides inside the slide rail 9, it can drive the lower surface of the slide rail 9 to be fixed on the upper surface of the first support plate 2, thereby realizing the effect of raising and lowering the second support plate 7, and flexibly adjusting the height of the sofa according to the user's body characteristics.

[0028] Reference Figure 2 and Figure 4 The baffle 10 has an inner shell 11, the outer wall of the outer shell 11 has a backrest 12, the inner shell 11 has a threaded block 13, the left outer wall of the threaded block 13 has a connecting rod 14, the left outer wall of the connecting rod 14 has a handle 15, the right outer wall of the threaded block 13 has a compression assembly, the compression assembly includes a spring 16, the left outer wall of the spring 16 has a fixed connection to the right outer wall of the threaded block 13, the right outer wall of the spring 16 has a fixed connection to a sliding block 17, the outer wall of the sliding block 17 has a slidably connected ball 18, the outer wall of the sliding block 17 has a slidably connected to the inner shell 11, the outer wall of the spring 16 has a compression connection to the inner shell 11, the outer wall of the ball 18 has a slidably connected to the inner shell 11, and the inner baffle 10 has a circular hole 19.

[0029] Specifically, when the handle 15 rotates, it can cause the right outer wall of the connecting rod 14 to rotate the left outer wall of the threaded block 13. When the right outer wall of the connecting rod 14 rotates the left outer wall of the threaded block 13, it can cause the outer wall of the threaded block 13 to rotate inside the outer shell 11. When the threaded block 13 rotates, it can cause the right outer wall of the spring 16 to slide the left outer wall of the sliding block 17. When the right outer wall of the spring 16 slides the left outer wall of the sliding block 17, it can cause the outer wall of the sliding block 17 to slide on the outer wall of the ball 18. When the sliding block 17 slides, it can cause the outer wall of the ball 18 to slide inside the outer shell 11. This allows the backrest 12 and the baffle 10 to be interchangeable, saving maintenance time and costs.

[0030] Working principle: When the sofa is needed, the motor 3 drives the threaded rod 4 to rotate, which causes the first support rod 5 to slide, further driving the second support rod 6 to rotate, causing the sliding plate 8 to slide, and then driving the second support plate 7 to rise and fall. This achieves the effect of raising and lowering the second support plate 7. By turning the handle 15, the connecting rod 14 is also rotated, causing the threaded block 13 to rotate, which in turn causes the spring 16 to compress, causing the sliding block 17 to slide, and then causing the ball 18 to slide. This allows the backrest 12 and the baffle 10 to be interchangeable. This not only makes the height of the coffee table or desk more suitable, but also allows the sofa height to be flexibly adjusted according to the user's body characteristics. It also allows for quick disassembly of damaged parts without disassembling or replacing the entire sofa, saving repair time and costs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
