[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions 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, 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 scope of protection of this utility model.

[0037] The following is combined with Figures 1-6 This invention describes a rhythmic motion frame and rhythmic furniture. The rhythmic furniture includes the aforementioned rhythmic motion frame and a supporting body. The supporting body can be moved rhythmically relative to the rhythmic motion by the reciprocating back-and-forth movement of the rhythmic motion frame. It is understood that, in embodiments of this invention, the aforementioned rhythmic furniture may be a rhythmic chair, a rhythmic bed, etc.

[0038] Reference Figures 1 to 6 According to this utility model, a rhythm frame is provided, including a fixed base frame 100, a rhythm support 200, and a drive mechanism 400. The rhythm support 200 is movably mounted on the fixed base frame 100, and a transmission structure 300 is provided on the rhythm support 200. The drive mechanism 400 includes a drive component 410 and a drive motor 420. The output shaft 421 of the drive motor 420 is fixedly connected to the drive component 410 to drive the drive component 410 to rotate. The drive component 410 has multiple drive positions 411, and the multiple drive positions 411 are in transmission cooperation with the transmission structure 300. The multiple drive positions 411 are at least two distances from the rotation center line of the drive component 410, one of which is A1 and the other is A2, where A1 is greater than A2.

[0039] The rhythmic frame provided by this utility model has at least two distances from the rotation center line of the drive component 410 to multiple drive positions 411. By providing A1 and A2, the drive positions 411 corresponding to A1 and A2 are switched and cooperated with the transmission structure 300 to drive the rhythmic bracket 200 to move back and forth relative to the fixed base frame 100. The drive mechanism 400 is driven smoothly, has a simple structure, is easy to install and operate, and effectively improves assembly efficiency.

[0040] It should be noted that, referring to Figure 1 In this embodiment of the utility model, the fixed base 100100 supports the rhythm bracket 200200. Of course, in some embodiments, the rhythm bracket 200200 can also be suspended above the fixed base 100100.

[0041] Understandably, referring to Figures 1 to 6In this embodiment of the utility model, the transmission structure 300 is provided with a transmission groove 310, the driving component 410 is limited to the transmission groove 310, and the multiple driving positions 411 of the driving component 410 can respectively abut against the two side walls opposite to the transmission groove 310.

[0042] The length of the transmission groove 310 is the sum of A1 and A2.

[0043] With the above structure, the total length of the transmission groove 310 is formed by adding two different dimensions A1 and A2. Designing the length of the transmission groove 310 as the sum of two parameters helps to optimize space utilization and make the structure more compact. Through the cooperation between the transmission groove 310 and the drive component 410, the drive component 410 can be accurately positioned to prevent it from exceeding the predetermined position, thereby improving the reliability and stability of the cooperation between the drive mechanism 400 and the transmission structure 300.

[0044] Specifically, refer to Figures 1 to 6 In this embodiment of the utility model, the transmission structure 300 includes a mounting base 320 and two transmission components 330. The mounting base 320 is connected to the rhythm bracket 200. The two transmission components 330 are spaced apart on the mounting base 320. The two transmission components 330 cooperate with the mounting base 320 to form a transmission groove 310. The multiple driving positions 411 of the driving component 410 can respectively abut and cooperate with the two transmission components 330.

[0045] Through the above-mentioned configuration, the connection between the mounting base 320 and the rhythm bracket 200, and the cooperation between the transmission component 330 and the mounting base 320, the transmission structure 300 has good rigidity and stability, which helps to transmit force and motion. The cooperation between the two transmission components 330 and the mounting base 320 forms a transmission groove 310, which can provide a clearly positioned transmission path for the drive component 410, which helps to transmit force and motion effects. In addition, the abutting cooperation between the multiple drive positions 411 of the drive component 410 and the two transmission components 330 helps to ensure the precise cooperation of each component during the installation process, improves the accuracy of installation, and makes maintenance more convenient.

[0046] Specifically, refer to Figure 3 and Figure 5 In this embodiment of the invention, the transmission component 330 is a rotating wheel rotatably mounted on the mounting base 320. Using a rotating wheel in conjunction with the drive component 410 helps reduce friction between components, lowers the possibility of wear and damage, and extends service life.

[0047] Specifically, refer to Figure 3 and Figure 5 In this embodiment, the mounting base 320 is provided with a mounting shaft, and the transmission component 330, i.e., the rotating wheel, is rotatably mounted on the mounting shaft through a bearing component, resulting in a stable structure and smooth rotation.

[0048] Of course, in some embodiments, the transmission component 330 may also be fixedly disposed on the mounting base 320, or in some embodiments, the mounting base 320 may have a transmission groove 310 formed inward, which is not limited here.

[0049] Specifically, refer to Figure 1 , Figures 4 to 6 In this embodiment of the utility model, the mounting base 320 includes a first plate 321 and a second plate 322, which are connected at an angle. At least one of the first plate 321 and the second plate 322 is connected to the rhythm bracket 200. Two transmission components 330 are mounted on the first plate 321, and the second plate 322 is used to cover the transmission components 330 and the drive components 410.

[0050] The structure described above, in which the first plate 321 and the second plate 322 are connected at an angle, can increase the stability and rigidity of the structure and help reduce deformation when transmitting force and moving. The second plate 322 is used to shield the transmission component 330 and the drive component 410, which can protect these components from the influence of the external environment, extend their service life and reduce maintenance requirements.

[0051] It should be noted that, referring to Figure 1 , Figures 4 to 6 In this embodiment, the included angle between the first plate 321 and the second plate 322 is degrees. Of course, in some embodiments, the included angle can be other angles, such as degrees, etc., which are not limited here. In some embodiments, the first plate 321 and the second plate 322 can be connected to the rhythm bracket 200 by welding, bolting, or snap-fitting. For example, the first plate 321 is fixedly connected to the rhythm bracket 200 by welding, or the second plate 322 is fixedly connected to the rhythm bracket 200 by welding, or both the first plate 321 and the second plate 322 are fixedly connected to the rhythm bracket 200 by welding, which are not limited here.

[0052] It should also be noted that in some embodiments, the first plate 321 and the second plate 322 may be integrally formed, or the first plate 321 and the second plate 322 may be fixedly connected by welding, bolting or other means.

[0053] Specifically, refer to Figure 1 , Figures 4 to 6The driving component 410 has a circular outline, and its rotation center line does not coincide with the center of the circle. This can be understood as the driving component 410 being an eccentric wheel. Because its rotation center line does not coincide with the center of the circle, the driving component 410 will generate eccentric motion during rotation, thereby driving the rhythmic support 200 to reciprocate. This eccentric configuration helps reduce the overall size, making the design more compact. It can be understood that the sum of A1 and A2 is the diameter of the eccentric wheel.

[0054] Specifically, refer to Figure 1 , Figures 4 to 6 In some other embodiments of this utility model, the driving component 410 is a Reuleaux triangle, and the driving position 411 is an arc surface formed on the outer contour of the Reuleaux triangle. Through the above structure, the geometry of the Reuleaux triangle helps the driving component 410 to smoothly transmit power to the transmission structure 300, resulting in flexible transmission. The multiple driving positions 411 on the outer contour can effectively utilize the surface area of ​​the triangle, making the overall structure more efficient in space utilization, simple and compact, and with good stability. Furthermore, the arc surface of the driving position 411 ensures a smoother transition during rotation and avoids wear on the transmission component 330, thus improving its service life.

[0055] It should be noted that the outer contour of the drive component 410 can be a complete Reuleaux triangle or an approximate Reuleaux triangle, and is not limited here.

[0056] Understandably, referring to Figure 1 , Figure 2 and Figure 4 In this embodiment of the utility model, the drive mechanism 400 further includes a fixed base 430, which is connected to the fixed base frame 100. The fixed base 430 is provided with a clearance channel 431. The drive motor 420 is installed on one side of the fixed base 430, and the transmission structure 300 and the drive component 410 are located on the opposite side of the fixed base 430. The output shaft 421 of the drive motor 420 passes through the clearance channel 431 and is fixedly connected to the drive component 410.

[0057] By adopting the above structure, by mounting the drive motor 420 on one side of the fixed base 430 and having its output shaft 421 pass through the clearance channel 431, space can be better utilized, and interference between the drive motor 420 and the transmission structure 300 when they are on the same side can be avoided. Separating the drive motor 420 and the transmission structure 300 can simplify the maintenance and adjustment process, improve maintainability and convenience. In addition, the connection between the fixed base 430 and the fixed base frame 100 provides stable support, which helps to enhance structural stability and reduce vibration and noise.

[0058] Specifically, refer to Figure 1 , Figure 5and Figure 6 In this embodiment of the invention, the drive mechanism 400 further includes a limiting member 440 and a connecting member 450. The drive component 410 is provided with an installation channel 412. The output shaft 421 of the drive motor 420 is circumferentially fixedly inserted into the installation channel 412. One side of the drive component 410 abuts against the output shaft 421 of the drive motor 420, and the opposite side of the drive component 410 abuts against the limiting member 440. The connecting member 450 passes through the limiting member 440 and is fixedly connected to the output shaft 421 of the drive motor 420. With the above structure, the cooperation between the limiting member 440 and the output shaft 421 of the drive motor 420 restricts the drive component 410 from disengaging from the drive motor 420, thereby improving the reliability and stability of the transmission.

[0059] Specifically, in this embodiment of the present invention, the output shaft 421 of the drive motor 420 is provided with limiting concave surfaces on both sides. The bottom surface of the limiting concave surface is inserted into the mounting channel 412 of the drive component 410 along with the output shaft 421. The other side of the limiting concave surface abuts against one side of the drive component 410. In this embodiment, the cross-sectional area of ​​the limiting member 440 is larger than the cross-sectional area of ​​the mounting channel 412. Therefore, the limiting member 440 abuts against the opposite side of the drive component 410, thereby limiting the installation position of the drive component 410.

[0060] It should be noted that in this embodiment, the connecting member 450 is a connecting bolt. Of course, in some embodiments, the connecting member 450 can also be a snap-fit ​​member, which engages with the output shaft 421 of the drive motor 420. This is not limited here. The number of the transmission structure 300 and the drive mechanism 400 is limited here, and they can both be set to two or three sets, etc.

[0061] It is understood that, referring to ,1, in this embodiment of the utility model, a guide mechanism 500 is provided between the fixed base frame 100 and the rhythm support 200 for connecting the two and guiding their relative movement.

[0062] Through the above structure, the guide mechanism 500 ensures that the relative movement between the fixed base frame 100 and the rhythmic support 200 is along a predetermined path, reducing wear and jamming problems caused by uneven relative movement or deviation from the trajectory; effective guidance can reduce vibration and noise caused by uneven movement, and improve the smoothness and comfort of operation.

[0063] Specifically, in this embodiment, the guiding mechanism 500 includes a first guide seat, a second guide seat, and a plurality of balls. The first guide seat is connected to the fixed base 100, and the second guide seat is connected to the rhythmic support 200. The first and second guide seats are slidably connected, and a receiving groove is formed between the first and second guide seats. The plurality of balls are rotatably installed in the receiving groove. With the above structure, when the rhythmic support 200 moves back and forth relative to the fixed base 100, it is guided by the relative sliding of the first and second guide seats. The inclusion of balls reduces the sliding resistance of the rhythmic support 200 relative to the fixed base 100, ensuring stability, reliability, and smooth movement. Of course, in some embodiments, the guiding mechanism 500 may also include a guide rail and a sliding seat slidably connected to the guide rail; this is not limited here.

[0064] It should be noted that in this embodiment, the guide mechanism 500 is arranged in four groups, which are distributed at intervals at the bottom of the fixed base frame 100 and the rhythmic support 200, that is, four groups of guide mechanisms 500 are arranged at intervals in the left, right, front, and back to provide stability for reciprocating forward and backward movement. Of course, in some embodiments, the guide mechanism 500 may be one or two groups, etc., which is not limited here.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
