This invention has the advantage of easy assembly and disassembly.

[0004] Although the aforementioned patent allows for the disassembly and assembly of the sofa through the use of multiple snap-fit ​​components, common sofas are typically placed in groups, making it difficult to easily connect and disassemble multiple sofas; furthermore, the functionality of the sofa is limited, failing to meet the needs of multi-functional use; therefore, a sofa that is easy to disassemble and assemble is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, common sofas are placed in groups, and it is not easy to connect and disassemble multiple sofas; at the same time, the functionality of sofas is poor and cannot meet the needs of multi-functional use. This utility model proposes a sofa that is easy to disassemble and assemble.

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

[0024] Please see Figures 1-4 As shown, a sofa that is easy to assemble and disassemble includes a sofa body 1. The bottom surface of the sofa body 1 is provided with a rectangular array of connecting components 2. The sofa body 1 is provided with an installation plate 3 inside. The side of the installation plate 3 is provided with a plurality of massage components 4. The massage components 4 include a side plate 41 fixed to the side of the installation plate 3. A drive motor 42 is fixed to the back of the side plate 41. Its output end passes through the side plate 41 and is connected to a drive rod 43. The drive rod 43 is connected to a driven rod 45 through a transmission belt 44. Massage balls 46 are provided at the ends of the drive rod 43 and the driven rod 45. A soft pad 47 covering the massage balls 46 is provided on the side of the side plate 41. A silicone pad 48 is provided on the outside of the soft pad 47.

[0025] During operation, the output of the drive motor 42 drives the active rod 43 to rotate, which in turn drives the driven rod 45 to rotate synchronously with the active rod 43 via the transmission belt 44. The massage balls 46 fixed to the ends of the two rods then form a rotating massage action inside the soft pack 47. The rigid structure of the soft pack 47 covering the side plate 41 forms a flexible contact layer. The silicone pad 48 on the outside of the soft pack 47 coincides with the movement trajectory of the massage balls 46, so that the rotating massage force is evenly transmitted to the human body after being buffered by the silicone pad 48. At the same time, it avoids the safety hazards caused by exposed mechanical parts, and achieves a dual optimization of comfort and functionality.

[0026] Furthermore, the connecting component 2 includes a base 21 and a connecting rod 22 inserted into the base 21. The base 21 and the connecting rod 22 are connected by a limiting rod 23 that passes through the limiting hole. The limiting rod 23 has elastic inserts 24 in the insertion holes at both ends.

[0027] During operation, the base 21 is connected to the connecting rod 22 at the bottom of another sofa body 1 via a horizontal insertion method. After the base 21 and the limiting hole of the connecting rod 22 are inserted, a coaxial through structure is formed. At this time, the limiting rod 23 is inserted into the aligned limiting hole, and the elastic insert 24 is inserted into the insertion holes at both ends of the limiting rod 23 in an interference fit manner, so as to achieve quick locking of the base 21 and the connecting rod 22. When disassembly is required, the adjacent sofa body 1 can be separated simply by pulling out the elastic insert 24 and removing the limiting rod 23. This structure significantly improves the disassembly and assembly efficiency and connection stability of the sofa through modular insertion and elastic limiting design.

[0028] Furthermore, a bearing 5 is sleeved on the end of the driven rod 45 away from the massage ball 46, and the outer ring of the bearing 5 is fixedly connected to the side of the side plate 41 to form a rotational support structure.

[0029] During operation, when the drive motor 42 drives the active rod 43 to rotate, the transmission belt 44 drives the driven rod 45 to rotate synchronously around the inner ring of the bearing 5. The rolling friction characteristics of the bearing 5 significantly reduce the rotational resistance of the driven rod 45. At the same time, by limiting the radial offset of the driven rod 45, the parallel transmission stability between the active rod 43 and the driven rod 45 is ensured. This structure reduces mechanical wear and noise through the rigid support and friction-reducing design of the bearing 5, extends the service life of the massage component 4, and improves the smoothness of the massage action.

[0030] Furthermore, the soft pad 47 covers the front of the side panel 41 to form a flexible contact surface, and the silicone pad 48 is bonded to the outer surface of the soft pad 47 and corresponds to the movement trajectory of the massage ball 46;

[0031] During operation, the silicone pad 48 is laminated to the outer surface of the soft pack 47 through a molding process. Its thickness matches the rotation trajectory of the massage ball 46. When the massage ball 46 rotates, the silicone pad 48 is compressed and deformed to buffer the massage force. At the same time, the soft pack 47 isolates the rigid structure of the side plate 41, ensuring that the contact surface with the human body is always made of flexible material. This design, through the double-layer buffering of the soft pack 47 and the silicone pad 48, avoids the massage ball 46 directly rubbing against the human body and causing discomfort, while the elastic deformation of the silicone pad 48 enhances the massage force feedback, achieving a dual optimization of safety and comfort.

[0032] Furthermore, the connecting rod 22 and the base 21 are connected by a horizontal insertion method. After the bottom support 21 and the limiting hole of the connecting rod 22 are inserted, they form a coaxial through structure. The elastic insert 24 is inserted into the insertion holes at both ends of the limiting rod 23 in an interference fit to form a detachable limiting.

[0033] During operation, after the limiting rod 23 is inserted into the channel, the elastic insert 24 is pressed into the insertion holes at both ends of the limiting rod 23 with an interference fit. The expansion force of the elastic insert 24 is used to lock the limiting rod 23 and prevent it from accidentally coming out. This structure simplifies the connection steps between the sofa body 1 through horizontal insertion and quick locking of the elastic insert 24. At the same time, the rigid fit between the limiting rod 23 and the base 21 and connecting rod 22 ensures the connection stability and solves the problems of low efficiency and easy loosening of traditional bolt connections. It is suitable for multi-sofa modular splicing scenarios.

[0034] Working principle: The sofa body 1 is modularly assembled and disassembled through the connecting components 2 distributed in a rectangular array on the bottom surface. The bottom support 21 is horizontally inserted into the connecting rod 22 at the bottom of another sofa body 1. The limiting rod 23 is inserted into the limiting hole aligned with the two, and the two ends are locked by the interference fit of the elastic insert 24 to form a rigid connection structure. The mounting plate 3 inside the sofa body 1 supports the massage component 4. The drive motor 42 is fixed to the back of the side panel 41 and drives the active rod 43 to rotate. The driven rod 45 is driven to rotate synchronously through the transmission belt 44. The massage balls 46 at the ends of the active rod 43 and the driven rod 45 roll along the inner surface of the silicone pad 48 under the soft pad 47. The silicone pad 48 buffers the massage force through elastic deformation. The bearing 5 is fixed to the side of the side panel 41 through the outer ring to support the end of the driven rod 45 to ensure transmission stability. The combination of the limiting of the elastic insert 24 of the connecting component 2 and the flexible contact design of the massage component 4 realizes the integrated operation of quick sofa splicing and comfortable massage function.
