[0032] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The following combination Figures 1-4 The present invention describes a rhythmic frame and rhythmic furniture that can move forward and backward. The rhythmic furniture includes the above-mentioned rhythmic frame and a supporting body mounted on the rhythmic frame. It is understood that in the embodiment of the present invention, the above-mentioned rhythmic furniture can be a rhythmic chair, a rhythmic bed, etc.

[0034] Reference Figures 1 to 3 The present invention provides a rhythmic frame that moves back and forth, and the rhythmic frame includes a fixed base frame 100, a rhythmic frame 200 and a support and guide mechanism 400. The rhythmic frame 200 is arranged above the fixed base frame 100, and the rhythmic frame 200 is configured to move back and forth relative to the fixed base frame 100. The driving mechanism 300 is arranged on the fixed base frame 100, and the output end of the driving mechanism 300 is transmission-connected to the rhythmic frame 200. The support and guide mechanism 400 includes a rotating member 410 and two support seats 420. The support seats 420 are provided with a supporting and fixing portion 421 and a rotating connection portion 422. The supporting and fixing portion 421 of one support seat 420 is fixedly connected to the upper surface of the fixed base frame 100, and the supporting and fixing portion 421 of the other support seat 420 is fixedly connected to the lower surface of the rhythmic frame 200. The opposite ends of the rotating member 410 are rotatably connected to the rotating connection portions 422 of the two support seats 420, respectively.

[0035] The present invention provides a rhythmic frame that moves back and forth, and the rotatable connection between the rotating connection portion 422 of the support seat 420 and the rotating member 410 allows the rhythmic bracket 200 to perform rhythmic back and forth motion relative to the fixed base frame 100 during installation and subsequent use. The above design reduces the requirement for precise alignment during installation because the rotating connection allows a certain degree of error and adjustment, thereby simplifying the installation process.

[0036] Through this fixed connection design of the upper and lower surfaces, the interaction between the rhythmic support 200 and the fixed base 100 is optimized, which not only ensures the stability of the structure, but also improves the safety and reliability during use. Because the design of the support base 420 already provides sufficient stability, the rhythmic support 200 does not require an additional support structure to enhance stability. The above-mentioned integrated design reduces the number of components, thereby reducing production costs. The two support bases 420 are respectively fixed to the fixed base 100 and the rhythmic support 200. This design effectively disperses the force generated during the forward and backward rhythm, improving the overall stability. At the same time, this design avoids complex support structures and reduces manufacturing costs.

[0037] It is understood that in the embodiment of the present invention, the rotating connection part 422 and the supporting and fixing part 421 are arranged adjacent to each other. The adjacent arrangement means that the rotating connection part 422 and the supporting and fixing part 421 are very close in space, which can reduce the size of the overall structure and make the design more compact. Moreover, since the rotating connection part 422 and the supporting and fixing part 421 are adjacent to each other, the torque generated by the rotating member 410 is more directly transmitted to the supporting structure, which helps to improve the force transmission efficiency and the movement accuracy of the rhythmic bracket 200. In addition, the adjacent arrangement can make the material between the supporting and fixing part 421 and the rotating connection part 422 continuous, thereby enhancing the structural strength and durability of this area. The compact design helps to reduce vibration caused by structural gaps because the close fit between the rotating connection part 422 and the supporting and fixing part 421 can effectively absorb and disperse vibration energy. The adjacent arrangement makes it more convenient to adjust the rotating connection part 422 because the operating space is concentrated, and maintenance personnel can make adjustments and inspections more easily.

[0038] In this embodiment of the present invention, the orthographic projections of the support fixing portion 421 and the rotating connection portion 422 on the horizontal plane are offset, meaning that the positions of the support points do not completely overlap. This design increases installation flexibility and allows for fine-tuning of the bracket during installation to accommodate different installation conditions, reducing installation difficulty.

[0039] Specifically, refer to Figure 1 and Figure 3 In the embodiment of the present invention, the rotating connection portion 422 and the supporting fixing portion 421 are configured as an integrated structure.

[0040] With the above-described structure, the integrated structure means that the support fixing portion 421 and the rotating connection portion 422 are designed and manufactured as a single unit, which improves the structural integrity and reduces the number of components. An integrated design is generally stronger than a structure assembled from multiple independent components because it reduces the number of joints, thereby increasing the strength and stability of the entire support structure. Because the support fixing portion 421 and the rotating connection portion 422 are integrally formed, the assembly process becomes simpler and faster, reducing assembly time and potential errors.

[0041] Of course, in some embodiments, the rotating connection portion 422 and the supporting and fixing portion 421 may also be assembled separately, for example, by connecting bolts or snap-fitting, etc., which is not limited here.

[0042] Specifically, refer to Figure 1 and Figure 3 In the embodiment of the present invention, when the rhythmic frame is at rest, the installation positions of the rotating connection parts 422 of the two support seats 420 are configured so that their orthographic projections on the horizontal plane coincide.

[0043] With this structure, the overlapping mounting positions help ensure the rhythmic frame maintains horizontal balance when stationary, which is important for preventing the frame from tilting when not in use. When the orthographic projections of the rotating connection portions 422 overlap, the load is more evenly distributed across the two support bases 420, reducing the pressure on a single support point and thus improving the durability of the structure.

[0044] Specifically, refer to Figure 1 and Figure 3 In the embodiment of the present invention, two support bases 420 are arranged facing each other.

[0045] With this structure, the two opposing support bases 420 can secure the rhythmic support 200 from two directions, forming a more stable support frame and reducing shaking and instability of the rhythmic support 200 during movement. During the rhythmic movement, the opposing support bases 420 help optimize the distribution of torque and reduce vibration caused by torque imbalance.

[0046] Specifically, refer to Figure 1 and Figure 3 In the embodiment of the present utility model, the supporting and fixing portion 421 is a flat plate, and the rotating connecting portion 422 includes two connecting columns 4221 connected to a side wall of the flat plate, and the two connecting columns 4221 are spaced apart;

[0047] The rotating member 410 is located between the two connecting columns 4221 , and the rotating member 410 is rotatably connected to the two connecting columns 4221 .

[0048] Two mounting countersunk holes 4211 are provided on the flat plate body, and the two mounting countersunk holes 4211 are arranged in a one-to-one correspondence with the two connecting columns 4221 .

[0049] With the above structure, the support and fixing portion 421 of the flat plate provides a larger contact area, making the support more stable and helping to disperse and withstand the force from the rhythmic support 200; the two connecting columns 4221 are arranged at intervals and are rotatably connected to the rotating member 410, allowing the rhythmic support 200 to rotate freely within a certain range, increasing the flexibility of use. Because the rotating member 410 is located between the two connecting columns 4221, the force generated during rotation can be evenly distributed to the two connecting columns 4221, reducing local stress concentration. The mounting countersunk holes 4211 are arranged in a one-to-one correspondence with the connecting columns 4221, making the installation and adjustment of the rotating connection portion 422 more precise and convenient.

[0050] The connecting column 4221 is connected to one side wall of the flat plate, providing a stronger connection point and enhancing the strength and durability of the entire support structure. The rotating connection design of the connecting column 4221 and the rotating member 410 makes daily maintenance and replacement easier, without the need for a complicated disassembly process. The spaced-apart connecting columns 4221 and the rotating member 410 are compact in design, which helps to optimize space utilization, especially in space-constrained environments. The design of the connecting column 4221 increases the reliability of the support structure, reduces the risk of failure, and improves safety during use. The design of the flat plate and the connecting column 4221 can more easily achieve a uniform appearance, enhancing the overall aesthetics of the rhythmic furniture.

[0051] Specifically, refer to Figure 1 and Figure 3 In this embodiment, the mounting countersunk hole 4211 is used to install a fixing bolt, and the fixing bolt passes through the mounting countersunk hole 4211 and is fixedly connected to the fixed base frame 100 and the rhythmic bracket 200. For example, the fixing bolt passes through the fixed base frame 100 and is threadedly connected to the fixing nut, and the fixing bolt passes through the rhythmic base frame and is threadedly connected to the fixing nut.

[0052] Specifically, refer to Figure 1 and Figure 3 In this embodiment, the connecting column 4221 is provided with a connecting through-hole. The connecting shaft 430 is rotatably passed through the connecting through-holes of the two connecting columns 4221. A sleeve 440 is provided between the connecting shaft 430 and the connecting through-hole. The sleeve is sleeved on the outer wall of the connecting shaft 430. The sleeve can be a flexible sleeve, which can be a rubber sleeve. Due to its elastic properties, the rubber sleeve can absorb and disperse the impact and vibration generated by mechanical movement, thereby reducing the generation of noise. Of course, the flexible sleeve can also be a silicone sleeve. Of course, in some embodiments, the sleeve 440 can also be a bearing member, which is not limited here.

[0053] Specifically, in this embodiment, a wear-resistant washer 450 is provided between the side wall of the rotating member 410 and the side wall of the connecting column 4221. The wear-resistant washer 450 can reduce direct contact wear between the rotating member 410 and the connecting column 4221, thereby extending the service life of both.

[0054] Specifically, refer to Figure 1 and Figure 3 In this embodiment, four groups of support and guide mechanisms 400 are provided, and the four groups of support and guide mechanisms 400 are arranged at circumferential intervals between the fixed base frame 100 and the rhythmic support 200.

[0055] Using the above structure, it can be understood that, in this embodiment, the fixed base frame 100 and the rhythmic support 200 are both rectangular structures, and the four groups of support and guide mechanisms 400 are circumferentially spaced at the four corners of the fixed base frame 100, which helps to evenly distribute the load from the rhythmic support 200 to the fixed base frame 100, reduce local stress concentration, and improve the stability of the overall structure.

[0056] Of course, in some embodiments, the support and guide mechanism 400 can also be two groups, six groups, etc., and can be adaptively set according to needs and the shape of the rhythm frame.

[0057] Specifically, refer to Figure 1 and Figure 2 In an embodiment of the present invention, the rhythmic frame further includes a connecting structure, which includes a plurality of connecting springs 500 , and connecting springs 500 are respectively connected to opposite sides between the fixed base frame 100 and the rhythmic support 200 .

[0058] With the above structure, the connecting spring 500 can absorb and buffer the impact and vibration generated by the rhythmic bracket 200 during movement, reducing damage to the fixed base frame 100 and the overall structure. The elastic connection can make the movement of the rhythmic bracket 200 smoother, improve comfort during use and reduce impact on the user.

[0059] It should be noted that, in this embodiment, the above-mentioned connecting springs 500 are set to four. Of course, in some embodiments, the connecting springs 500 can also be two, six, etc., which can be adaptively set according to needs and the shape of the rhythm frame and other requirements.

[0060] It is understandable that, referring to Figure 1 and Figure 2In the embodiment of the present utility model, the driving mechanism 300 includes a driving motor 310, an eccentric shaft 320, a transmission rocker arm 330 and a transmission shaft 340. The driving motor 310 is disposed on the fixed base frame 100, and the eccentric shaft 320 is rotatably disposed on the fixed base frame 100. The output end of the driving motor 310 is transmission-connected to the eccentric shaft 320, one end of the transmission rocker arm 330 is eccentrically transmission-connected to the eccentric shaft 320, the transmission shaft 340 is rotationally connected to the rhythmic bracket 200, and the other end of the transmission rocker arm 330 is connected to the transmission shaft 340.

[0061] It can be understood that the rotation center line of the partial structure where the transmission rocker arm 330 and the eccentric shaft 320 cooperate does not coincide with the rotation center line of the partial structure where the output end of the drive motor 310 and the eccentric shaft 320 cooperate.

[0062] The driving motor 310 is mounted on the fixed base frame 100, and the eccentric shaft 320 is rotatably mounted on the fixed base frame 100. The output end of the driving motor 310 is connected to the eccentric shaft 320 through transmission, and one end of the transmission rocker arm 330 is eccentrically connected to the eccentric shaft 320 through transmission.

[0063] Reference Figure 4 In other embodiments of the present invention, the driving mechanism 300 includes a driving motor 310, an eccentric shaft 320, a transmission rocker arm 330 and a spring structure 350. The driving motor 310 is arranged on the fixed base frame 100, and the eccentric shaft 320 is rotatably arranged on the fixed base frame 100. The output end of the driving motor 310 is transmission-connected to the eccentric shaft 320, one end of the transmission rocker arm 330 is eccentrically transmission-connected to the eccentric shaft 320, one end of the spring structure 350 is connected to the other end of the transmission rocker arm 330, and the other end of the spring structure 350 is fixedly connected to the rhythmic bracket 200.

[0064] With the above structure, the spring structure 350 is solidly connected to the rhythmic bracket 200. The spring structure 350 is deformed and bent up and down instead of being rotated and connected to the rhythmic bracket 200 by the transmission shaft 340. The rotational motion generated by the drive motor 310 is converted into eccentric motion, thereby generating a periodic torque on the transmission rocker arm and the spring structure, so that the rhythmic bracket 200 reciprocates back and forth relative to the fixed base frame 100. The structure is compact and provides flexible, efficient and precise motion control.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
