DETAILED DESCRIPTION

[0035] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0036] The following describes the elastic base assembly and massage furniture of the present application with reference to Figures 1-4. The massage furniture includes a massage body that supports the user and an elastic base assembly disposed at the bottom of the massage body. It should be noted that in some embodiments of the present application, the massage furniture is a massage chair, and the elastic base assembly is located at the bottom of the massage chair. Of course, in some embodiments, the elastic base assembly can also be applied to furniture such as massage sofas and massage beds.

[0037] 1 to 3 , an elastic base frame assembly is provided according to the present application, including a first frame 100, a second frame 200, a driving mechanism 300 and a connecting structure 400. The second frame 200 and the first frame 100 can move relative to each other. The driving mechanism 300 is provided on the first frame 100. The output end of the driving mechanism 300 is transmission-connected to the second frame 200 to drive the second frame 200 to swing back and forth relative to the first frame 100. The connecting structure 400 includes a plurality of supporting springs 410. The connecting structure 400 includes a plurality of supporting springs 410. Support springs 410 are respectively connected to at least two opposite sides between the first frame 100 and the second frame 200. The elastic deformation direction of the support springs 410 is the direction of changing the spacing between the first frame 100 and the second frame 200.

[0038] The elastic base frame assembly provided by the present application is provided with a connecting structure 400 between the first frame body 100 and the second frame body 200 of the base frame assembly. During installation, it is only necessary to connect the two ends of the support spring 410 to the first frame body 100 and the second frame body 200 respectively to achieve the relative position support and coordination between the first frame body 100 and the second frame body 200, without the need to add other components, which is conducive to saving manpower and material resources for installation and is very convenient. In addition, the overall structure is simple, the failure rate is low, and it is easy to assemble and transport, which is conducive to reducing production costs and increasing market competitiveness. In addition, the support spring 410 is used to connect the first frame body 100 and the second frame body 200, and the elastic deformation of the support spring 410 The direction is to change the distance between the first frame 100 and the second frame 200. The elasticity of the support spring 410 can not only adapt to the distance change when the second frame 200 swings back and forth relative to the first frame 100, but also effectively compensate for the dimensional change caused by temperature change, thereby ensuring the accuracy or stability of the mechanical structure; and by designing the stiffness of the support spring 410 (that is, the force required for a unit length change), the first frame 100 and the second frame 200 can remain relatively stationary or maintain a certain tension within a certain range; at the same time, using the support spring 410 between the first frame 100 and the second frame 200 can provide a feedback on position or force according to the elastic deformation of the support spring 410.

[0039] Specifically, referring to Figures 1 to 3, in this embodiment of the present application, multiple support springs 410 are provided on each of the two opposing sides between the first frame 100 and the second frame 200. The support springs 410 on each side are spaced apart. By evenly distributing the support springs 410 on the opposing sides between the first frame 100 and the second frame 200, the overall stability of the structure is enhanced. When an external force acts on the second frame 200, the distributed support springs 410 disperse the force, reducing deflection or tilting caused by concentrated forces and ensuring the stability and reliability of the chassis assembly. The distributed arrangement of the multiple support springs 410 effectively disperses the load, improving the load-bearing capacity of the entire chassis assembly. Each support spring 410 participates in the load-bearing process, sharing the pressure between the first frame 100 and the second frame 200. This allows the support springs 410 to better withstand greater loads and prevent damage caused by overloading. The spaced support springs 410 effectively absorb and disperse impact forces from different directions, reducing direct damage to the first and second frames 100 and 200. This distributed buffer design can reduce the degree of damage and improve the overall impact resistance when facing sudden external impacts.

[0040] It should be noted that, referring to Figures 1 to 3, in the embodiment of the present application, the number of the above-mentioned support springs 410 is four, two support springs 410 are provided on the left side between the first frame 100 and the second frame 200, and the two support springs 410 are distributed at the front and rear ends between the first frame 100 and the second frame 200, and two support springs 410 are provided on the right side between the first frame 100 and the second frame 200, and the two support springs 410 are distributed at the front and rear ends between the first frame 100 and the second frame 200.

[0041] It will be appreciated that, with reference to Figures 1 to 3, in the embodiment of the present application, the first frame 100 and the second frame 200 are detachably connected to both ends of the support spring 410. This detachable connection allows the support spring 410 to be easily removed from the first frame 100 and the second frame 200 for replacement or repair when damaged or degraded, without having to replace the entire chassis assembly or undergo a complex disassembly process. This greatly simplifies maintenance procedures and reduces maintenance costs. Support springs 410 of different specifications or performance can be replaced as needed to accommodate different load conditions or usage requirements, providing greater flexibility and adjustability, allowing the entire structure to better meet diverse application requirements. Furthermore, different usage environments or conditions may require different types of support springs 410 to accommodate factors such as uneven ground and temperature fluctuations. The detachable connection allows users to select the appropriate spring based on actual conditions, enhancing the overall structure's adaptability to environmental changes.

[0042] Specifically, referring to Figures 1 to 3, in the embodiment of the present application, the first frame body 100 is provided with a first threaded member 110, and the second frame body 200 is provided with a second threaded member 210. The first threaded member 110 is threadedly connected to one end of the support spring 410, and the second threaded member 210 is threadedly connected to the other end of the support spring 410. The use of a detachable threaded connection provides a reliable and flexible solution for connecting the first frame body 100 and the second frame body 200 with the support spring 410. This method enhances the stability, safety, and adaptability of the structure, while also facilitating maintenance and adjustment. The preload force of the spring can be fine-tuned as needed, thereby optimizing the performance of the entire chassis assembly structure and reducing assembly costs.

[0043] Specifically, referring to Figures 1 to 3, the support spring 410 includes a cylindrical spring body 411, a first fixing post 412, and a second fixing post 413. The first fixing post 412 and the second fixing post 413 are respectively formed at opposite ends of the cylindrical spring body 411. The first fixing post 412 is threadedly connected to the first threaded member 110, and the second fixing post 413 is threadedly connected to the second threaded member 210. The design of integrating the cylindrical spring body 411 with the first and second fixing posts 412 and 413 at both ends, which are then threadedly connected to the first and second threaded members 110 and 210, not only provides a stable and reliable connection, but also increases the convenience of installation and maintenance, while allowing for precise adjustment of mechanical properties.

[0044] It should be noted that, in this embodiment, the first threaded member 110 and the second threaded member 210 are both connecting bolts, and the first fixing column 412 and the second fixing column 413 are both provided with threaded connection holes with internal threads, which are threadedly connected to the corresponding connecting bolts through the threaded connection holes; the first fixing column 412 and the second fixing column 413 are both welded or integrally formed with the cylindrical spring body 411, which is not limited here.

[0045] Of course, in one embodiment, the cylindrical spring body 411, the first fixing column 412 and the second fixing column 413 can also be fixedly connected by means of snapping, plugging, etc.; of course, the support spring 410 can also be fixedly connected to the first frame 100 and the second frame 200 by means of snapping, plugging, etc.

[0046] It can be understood that, referring to Figures 1 to 3, in the embodiment of the present application, the first frame 100 and the second frame 200 are arranged in parallel, the second frame 200 is spaced apart and stacked on top of the first frame 100, the upper end of the support spring 410 is connected to the second frame 200, and the lower end of the support spring 410 is connected to the first frame 100. The above structure is not only convenient for assembly and transportation, but also the design of the first frame 100 and the second frame 200 being stacked in parallel and connected by the support spring 410 not only effectively utilizes the vertical space, has greater adaptability, enhances the stability and elasticity of the structure, but also provides high flexibility and convenient maintenance.

[0047] It can be understood that, with reference to Figures 1 to 4, in the embodiment of the present application, the drive mechanism 300 includes a drive motor 310, a transmission assembly 320, and a rocker assembly 330. The drive motor 310 is disposed on the first frame 100, one end of the transmission assembly 320 is in transmission connection with the output shaft of the drive motor 310, one end of the rocker assembly 330 is in eccentric transmission connection with the other end of the transmission assembly 320, and the other end of the rocker assembly 330 is connected to the second frame 200. With the above structure, when the drive motor 310 is in operation, the eccentric transmission between the transmission assembly 320 and the rocker assembly 330 causes the second frame 200 to swing back and forth relative to the first frame 100. The eccentric arrangement is conducive to adjusting pressure, controlling vibration, and achieving mechanical transmission.

[0048] Specifically, referring to Figures 1 to 4, in the embodiment of the present application, the rocker arm assembly 330 includes a connecting base 331, an elastic connecting plate 332, and a swinging rocker arm 333.

The connecting base 331 and the swinging rocker arm 333 are spaced apart from each other. Due to the spacing between the opposite ends of the connecting base 331 and the swinging rocker arm 333, the elastic connecting plate 332 deforms to accommodate the upward and downward swing of the swinging rocker arm 333, thereby preventing upward and downward swinging when power is transmitted to the connecting base 331. This allows the connecting base 331 to more smoothly drive the second frame 200 to move relative to the first frame 100, resulting in smooth transmission, reduced noise, a simple structure, and low manufacturing cost.

[0049] It should be noted that, referring to Figures 1 to 4, in this embodiment, the swing rocker 333 also includes a first fixed plate 334 and a second fixed plate 335, and there is a distance between the first fixed plate 334 and the second fixed plate 335. The first fixed plate 334 corresponds to the swing rocker 333, and the second fixed plate 335 corresponds to the connecting seat body 331. One end of the elastic connecting plate 332 is clamped between the swing rocker 333 and the first fixed plate 334, and the other end is clamped between the connecting seat body 331 and the second fixed plate 335, which can further improve the assembly stability and transmission performance of the elastic connecting plate 332. It can be understood that the spacing between the first fixing plate 334 and the second fixing plate 335 is equal to the spacing between the opposite ends of the swing rocker 333 and the connecting seat body 331, which is conducive to making the elastic connecting plate 332 have consistent deformation amplitude when moving back and forth, thereby maintaining stability; the above-mentioned elastic connecting plate 332 can be a thinner steel plate or a rubber plate, and the swing rocker 333 and the connecting seat body 331 are both detachably connected to the elastic connecting plate 332 by bolting or the like.

The mating end surfaces of the first plate body, the second plate body, the first vertical plate body, and the two second vertical plates are fixedly connected by welding. Through the above structure, the splicing and welding method is adopted, so that the components of the connecting base body 331 play a role of limiting each other, which is conducive to preventing the rocker arm assembly 330 from shaking, thereby fixing the position of the rocker arm assembly 330.

[0051] Specifically, in some embodiments of the present application, the transmission assembly 320 includes an eccentric shaft, a driving pulley, a driven pulley, and a transmission belt. The eccentric shaft is rotatably disposed on the first frame 100. The rocker arm assembly 330 is in transmission connection with the eccentric shaft.
