[0002] A sofa frame is the structural framework that supports the seating area of ​​a sofa. It is typically made of materials such as wood, metal, or plastic, providing stability and load-bearing capacity. Common sofa frames include wooden frames, suitable for traditional designs and known for their sturdiness and durability; and metal frames, which are lighter and better suited for modern minimalist styles. Additionally, sofa frames may feature spring support systems, such as wave springs or pocket springs, to enhance comfort and distribute pressure. The design of the sofa frame not only affects the stability and durability of the sofa but also determines its comfort and appearance.

[0003] To enhance comfort, some sofa frames are designed with a rocking or swaying structure. This design is typically achieved through a curved base or a specially designed rocking support system, allowing the sofa to produce a slight swaying effect during use. This swaying sensation provides a relaxing and comfortable experience, similar to a rocking chair, helping users unwind. Rocking sofa frames not only improve comfort but also add a touch of entertainment and leisure.

[0004] Regarding the aforementioned technologies, the inventors believe that the aforementioned rocking structures are usually passive and cannot actively rock. They only produce a slight rocking effect during use based on changes in a person's posture and weight. For users who prefer stronger or more frequent rocking, the passive rocking structure cannot meet their needs. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a swing mechanism for a rocking sofa frame.

[0026] Reference Figures 1-2 A swing mechanism for a swinging sofa frame includes a connecting plate 1 and a connecting block 2. The connecting plate 1 is connected to the sofa frame, and the connecting block 2 is mounted on the connecting plate 1. A drive assembly 3 is mounted on the base of the sofa frame. The drive assembly 3 drives the connecting block 2 to swing. In addition, an error adjustment assembly 4 is provided between the drive assembly 3 and the connecting block 2. The error adjustment assembly 4 is used to eliminate assembly errors and part machining dimensional errors of the sofa frame, as well as machining errors and installation errors of the swing mechanism.

[0027] Reference Figures 2-3The drive assembly 3 includes a gearbox 31, with a base plate 32 on one side of the gearbox 31. One end of the base plate 32 is welded to the base of the sofa frame, and the gearbox 31 is mounted on the base plate 32. The gearbox 31 has a primary shaft 33 and a secondary shaft 34, and bearings 331 are installed at both ends of the primary shaft 33 and the secondary shaft 34. The primary shaft 33 and the secondary shaft 34 are rotatably mounted on the gearbox 31 through the bearings 331.

[0028] The gearbox 31 is equipped with a drive motor 35, a primary gear set 36, and a secondary gear set 37. The primary gear set 36 is mounted on a primary shaft 33 via pins, and the secondary gear set 37 is mounted on a secondary shaft 34 via pins. A worm gear 351 is connected to the output shaft of the drive motor 35. The primary gear set 36 meshes with the worm gear 351, and the secondary gear set 37 meshes with the primary gear set 36. In use, the primary gear set 36 or the secondary gear set 37 is selected according to the load of the sofa frame. When the load of the sofa frame is small, the drive motor 35 drives the sofa frame to swing through the primary gear set 36. When the load of the sofa frame is large, the drive motor 35 drives the sofa frame to swing through both the primary gear set 36 and the secondary gear set 37.

[0029] A drive block 38 is provided on one side of the gearbox 31. In use, the drive block 38 is mounted on the primary shaft 33 or the secondary shaft 34 via pins, depending on the selection. Power is transmitted through the primary gear set 36 or the secondary gear set 37. Compared with the belt drive in the prior art, the gear drive can reduce the occurrence of slippage, thereby making the entire sofa swing more smoothly and without slippage or jamming, thus making the swing smoother.

[0030] Reference Figures 3-4 During the swinging process of the sofa frame, in order to make the swinging of the sofa frame smoother, the error adjustment component 4 includes a bearing seat 41. The bearing seat 41 is rotatably connected to the drive block 38. The cross-section of the drive block 38 is rectangular, and one end of the drive block 38 in the length direction is connected to the primary shaft 33 or the secondary shaft 34. The bearing seat 41 is rotatably connected to the other end of the drive block 38 in the length direction.

[0031] Reference Figure 4 Furthermore, a connecting rod 42 is provided on the bearing housing 41, and a connecting groove 43 is provided on the bearing housing 41. One end of the connecting rod 42 passes into the connecting groove 43 of the bearing housing 41. A connecting bolt 44 is provided on the bearing housing 41. One end of the connecting bolt 44 passes through the bearing housing 41 and the connecting rod 42 in sequence. A fixing nut 45 is threadedly connected to the end of the connecting bolt 44 that passes through the bearing housing 41. One end of the fixing nut 45 is pressed against the bearing housing 41. In use, the connecting rod 42 is rotatably mounted on the bearing housing 41 through the connecting bolt 44.

[0032] The end of the connecting rod 42 furthest from the bearing seat 41 has a ball head 421. Two connecting blocks 2 are spaced apart on the connecting plate 1, and a rotating groove 21 is formed between the two connecting blocks 2. The two connecting blocks 2 are locked together by screws. In use, the ball head 421 of the connecting rod 42 is inserted into the rotating groove 21 of the two connecting blocks 2. The connecting rod 42 is rotatably connected to the connecting block 2 through the ball head 421, so that the connecting block 2 can rotate in all directions.

[0033] In actual installation and processing, sofa frame installation typically relies on manual operation, which may lead to assembly errors, dimensional errors in parts processing, and errors in the rocking mechanism during processing and installation. These errors can cause the rocking mechanism to swing unevenly, affecting the performance of the sofa frame. This application addresses these issues by using a drive assembly 3 and an error adjustment assembly 4. Specifically, a ball joint 421 is embedded in a rotating groove 21 located between two connecting blocks 2, allowing the ball joint 421 to rotate omnidirectionally between the connecting blocks 2. This design effectively eliminates errors generated during installation and processing, ensuring the stability and smoothness of the rocking mechanism, thereby improving the overall performance of the sofa frame.

[0034] In use, the drive motor 35 drives the first-stage gear set 36 and the second-stage gear set 37 to rotate through the worm gear 351. During the rotation of the first-stage gear set 36 and the second-stage gear set 37, the drive block 38 swings, which drives the bearing seat 41 to swing. The bearing seat 41 then drives the connecting rod 42 to swing. The connecting rod 42 drives the connecting plate 1 to swing through the connecting block 2. Since the connecting plate 1 is installed on the sofa frame, the drive motor 35 can drive the sofa frame to swing.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
