Description

Technical Field

[0001] This invention relates to a sports massage device, and more particularly to a motion motor that simultaneously drives a plurality of transmission mechanisms through an eccentric mechanism to drive a top frame in reciprocating motion. Prior Technology

[0002] A conventional vibration device is a type of lifting and lowering vibration apparatus, which has a rather complex structure and is quite inconvenient to assemble. The conventional lifting and lowering vibration apparatus includes a fixed frame, a transmission mechanism movably mounted on the fixed frame, a carrier connected to the transmission mechanism, and a driving component mounted on the fixed frame. The transmission mechanism includes a first shaft, a first transmission body, and a second transmission body. The middle portions of the first and second transmission bodies are rotatably mounted on the fixed frame. One end of the first and second transmission bodies is rotatably mounted on the first shaft. The other ends of the first and second transmission bodies are rotatably mounted on the carrier. The driving component drives the carrier to reciprocate up and down via the transmission mechanism, thus causing vibration.

[0003] It is worth noting that if a user steps on or stands on the aforementioned frame using their own weight, and the first shaft within the transmission mechanism alone enables the synchronous movement of the first and second transmission elements, the frame may not be able to maintain a horizontal reciprocating motion during lifting and lowering vibrations. Furthermore, with unstable mechanical vibrations, mechanical wear can easily occur between the shafts and multiple transmission elements within the transmission mechanism, potentially causing the connecting parts (e.g., nuts, screws, and washers) to break or loosen.

[0004] In view of this, given the problems of the aforementioned conventional lifting and vibration devices, the public eagerly anticipates the development of a stable and simple mechanism that can maintain reciprocating motion, while also improving user comfort and reducing manufacturing costs. This is also the goal and direction that relevant businesses must strive to achieve through research and development. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide a rhythmic motion device that simultaneously drives a plurality of transmission mechanisms via an eccentric mechanism, causing the top frame of the first and second transmission components disposed in each transmission mechanism to reciprocate. Furthermore, the power of the rhythmic motion device is evenly distributed on the first and second connecting shafts pivotally mounted on the first and second transmission components, as well as at the contact points between the top frame and the first and second transmission components. Thus, the rhythmic motion device of the present invention provides a smoother rhythmic motion than conventional lifting and vibrating devices, reducing uneven power distribution, thereby decreasing mechanical wear and component vibration, improving the user's perception of impact during the reciprocating motion of the rhythmic motion, and achieving a wave-like rhythm, further expanding the functionality and user experience of the rhythmic motion device.

[0006] According to one embodiment of the present invention, a rhythmic actuator is provided, comprising a base, a rhythmic unit, and a top frame.

The second movable connecting plate is pivotally mounted between the two additional bearing seats, and one end of the second movable connecting plate is pivotally connected to a second connecting shaft. One end of each connecting plate is pivotally connected to the other end of the second movable connecting plate. The two additional fixed seats are fixed to the top frame and provide pivot mounting for the other ends of each connecting plate. The second movable connecting plate is driven by the second connecting shaft and moves in a seesaw motion with the two additional bearing seats as fulcrums.

[0012] Other embodiments of the aforementioned implementation are as follows: the length of the first movable connecting plate is M1, and the length of the second movable connecting plate is M2, which can satisfy the following condition: 0.5 ≤ M1 / M2 ≤ 2.

[0013] Other embodiments of the aforementioned implementation are as follows: the length of the second movable connecting plate is M2, and the length of the second transmission plate is M3, which can satisfy the following conditions: 1.25 ≤ M2 / M3 ≤ 6.

[0014] Other embodiments of the aforementioned implementation are as follows: the first connecting shaft and the second connecting shaft may not be connected and have the same axial direction.

[0015] Other embodiments of the aforementioned implementation are as follows: at a certain point in time, there is a first distance between the top frame and the base at the first transmission component, and a second distance between the top frame and the base at the second transmission component, wherein the first distance and the second distance may be equal.

[0016] Other embodiments of the aforementioned implementation are as follows: the first connecting shaft and the second connecting shaft may not be connected, and both the first transmission plate and the second transmission plate are pivotally connected to the eccentric shaft and form a V-shape.

[0017] Other embodiments of the aforementioned implementation are as follows: the included angle of the V-shape can be between 5 degrees and 30 degrees.

[0018] Other embodiments of the aforementioned implementation are as follows: at a certain point in time, there is a first distance between the top frame and the base at the first transmission component, and a second distance between the top frame and the base at the second transmission component. The first distance and the second distance may not be equal.

[0019] According to another embodiment of the present invention, a rhythmic actuator is provided, comprising a base, a rhythmic unit, and a top frame. The rhythmic unit includes a drive mechanism, an eccentric mechanism, and two transmission mechanisms. The drive mechanism is disposed on the base. The eccentric mechanism is connected to the drive mechanism and includes an eccentric shaft. The two transmission mechanisms are disposed opposite to each other on the base, and each transmission mechanism includes a first transmission plate, a second transmission plate, a first connecting shaft, a second connecting shaft, a first transmission assembly, and a second transmission assembly. The first transmission plate is disposed on the eccentric shaft. The second transmission plate is disposed on the eccentric shaft.

The eccentric mechanism is driven by the drive mechanism and drives each first transmission plate and each second transmission plate, so that each first connecting shaft reciprocates along a first direction and each second connecting shaft reciprocates along a third direction. The first transmission component of each transmission mechanism is driven by the first connecting shaft to drive the top frame to reciprocate along a second direction. The second transmission component of each transmission mechanism is driven by the second connecting shaft to drive the top frame to reciprocate along a fourth direction. The first direction is different from the second direction, and the third direction is different from the fourth direction.

[0020] In this way, even when the user focuses their foot on a specific area of ​​the top frame, the vibration motor of this invention can still maintain synchronous operation of multiple transmission mechanisms through the first and second linkage shafts connecting each transmission mechanism. This prevents components from breaking or becoming loose due to resistance, and the buffer unit assists the top frame in supporting the pressure, which facilitates the effortless operation of the drive mechanism.

[0022] Other embodiments of the aforementioned implementation are as follows: the horizontal drive unit may further include a horizontal swing arm, which is pivotally connected to the base and the horizontal eccentric rocker arm, so that the horizontal drive unit drives the base to vibrate horizontally.

Implementation

[0024] The embodiments of the present invention will be described below with reference to the accompanying drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, these practical details are not essential in the embodiments of the present invention. Furthermore, for the sake of simplicity, some conventional structures and elements will be shown in a simple schematic manner in the drawings; and repeated elements may be represented by the same number.

[0025] Furthermore, in this document, when a component (or unit or module, etc.) is "connected / linked" to another component, it can mean that the component is directly connected / linked to the other component, or it can mean that the component is indirectly connected / linked to the other component, that is, there is another component between the component and the other component. Only when it is explicitly stated that a component is "directly connected / linked" to another component does it mean that there is no other component between the component and the other component. The terms "first," "second," "third," etc., are only used to describe different components and do not limit the components themselves; therefore, the first component can also be referred to as the second component. Moreover, the combinations of components / units / circuits in this document are not combinations that are generally known, conventional, or customary in this field. The ease with which a person with ordinary knowledge in the art can easily complete their combination relationship cannot be determined by whether the component / unit / circuit itself is customary.

[0026] Please refer to Figures 1 through 4 together, wherein Figure 1 is a perspective view of a rhythmic motion device 10 according to an embodiment of the present invention; Figure 2 is an exploded view of the rhythmic motion device 10 of Figure 1; Figure 3 is a top view of the rhythmic unit 100 and the horizontal drive unit 800 of the rhythmic motion device 10 of Figure 2; and Figure 4 is an exploded view of the two transmission mechanisms 400 of the rhythmic unit 100 of the rhythmic motion device 10 of Figure 2. As shown in Figures 1 through 4, the rhythmic motion device 10 includes a base 101, a rhythmic unit 100, a top frame 500, and a plurality of feet 600. The rhythmic unit 100 includes a drive mechanism 200, an eccentric mechanism 300, and two transmission mechanisms 400.

[0027] The drive mechanism 200 and the eccentric mechanism 300 are disposed on the base 101. The eccentric mechanism 300 is connected to the drive mechanism 200 and includes an eccentric shaft 320 and two eccentric wheels 330. The two eccentric wheels 330 are respectively sleeved and pivotally connected to the two ends (including positions close to the two ends) of the eccentric shaft 320, and the structure or counterweight of each of the two eccentric wheels 330 is asymmetrical with respect to the eccentric shaft 320. Two transmission mechanisms 400 are disposed opposite to each other on the base 101. Each transmission mechanism 400 is adjacent to and corresponds to an eccentric wheel 330 and includes a first transmission plate 410, a second transmission plate 412, a first connecting shaft 420, a second connecting shaft 422, a first transmission component 430, and a second transmission component 440. The first transmission plate 410 is mounted on the eccentric shaft 320 via a bearing assembly. The eccentric shaft 320 and the first connecting shaft 420 are parallel to each other. The eccentric shaft 320 passes through the bearing of the first transmission plate 410, and the first connecting shaft 420 passes through the first transmission plate 410. The first transmission plate 410 is directly connected to and surrounds the first connecting shaft 420, meaning there is no bearing between the first transmission plate 410 and the first connecting shaft 420. The second transmission plate 412 is mounted on the eccentric shaft 320 via a bearing assembly. The eccentric shaft 320 and the second connecting shaft 422 are parallel to each other. The eccentric shaft 320 passes through the bearing of the second transmission plate 412, and the second connecting shaft 422 passes through the second transmission plate 412. The second transmission plate 412 is directly connected to and surrounds the second connecting shaft 422, meaning there is no bearing between the second transmission plate 412 and the second connecting shaft 422. The first transmission assembly 430 is pivotally mounted on the first connecting shaft 420, and the second transmission assembly 440 is pivotally mounted on the second connecting shaft 422. The top frame 500 is disposed on the first transmission assembly 430 and the second transmission assembly 440 of each transmission mechanism 400, and the top frame 500 may be the housing of the vibrator 10, or the top frame 500 may be connected to the housing of the vibrator 10.

[0028] Furthermore, the eccentric mechanism 300 is driven by the drive mechanism 200, which in turn drives each of the first transmission plates 410 and each of the second transmission plates 412, so that each of the first connecting shafts 420 reciprocates (periodic motion) along a first direction (same as the third direction D3 in Figure 7A) and each of the second connecting shafts 422 reciprocates along a third direction D3 (shown in Figure 7A). The first transmission component 430 of each transmission mechanism 400 is driven by the first connecting shaft 420 to drive the top frame 500 to reciprocate along a second direction D2 (shown in Figure 7A). The second transmission component 440 of each transmission mechanism 400 is driven by the second connecting shaft 422 to drive the top frame 500 to reciprocate along a fourth direction D4 (shown in Figure 7A). The first direction is different from the second direction D2, and the third direction D3 is different from the fourth direction D4. In addition, each foot 600 is detachably mounted on the base 101. The foot 600 has a height that prevents the lower edge of the base 101 from hitting the ground during rhythmic movement.

[0029] Therefore, the rhythmic motion device 10 of the present invention uses the drive mechanism 200 to drive the eccentric mechanism 300, and the eccentric mechanism 300 drives the first transmission plate 410 and the first connecting shaft 420 through eccentric rotation, and simultaneously drives the second transmission plate 412 and the second connecting shaft 422. Furthermore, the buffer units 883 and 884 assist the top frame 500 in supporting pressure, thereby facilitating the effortless drive of the drive mechanism 200. Thus, the top frame 500, driven by the first transmission assembly 430 and the second transmission assembly 440, performs reciprocating motion in a different direction from the first connecting shaft 420 and the second connecting shaft 422, thereby providing exercise and muscle relaxation effects for the user stepping on the top frame 500. The up-and-down rhythmic motion also achieves the purpose of exercising the user, and the buffer units 883 and 884 improve the user's sense of impact during the reciprocating motion of the rhythmic motion device 10, thereby enhancing user comfort. Furthermore, the rhythm unit 100 of the present invention can be designed to move vertically up and down or in a wave-like manner, further expanding the function and user experience of the rhythm unit 100 and providing design flexibility.

[0030] Furthermore, the power of the rhythmic motion device 10 is evenly distributed on the first connecting shaft 420 and the second connecting shaft 422 of each transmission mechanism 400, as well as at the contact points between the top frame 500 and the first transmission assembly 430 and the second transmission assembly 440. Therefore, the rhythmic motion device 10 is more stable and less prone to uneven power distribution during rhythmic operation than conventional lifting and vibration devices, thereby reducing mechanical wear and component vibration.

[0031] Please refer to Figures 2 through 5, where Figure 5 is an exploded view of the drive mechanism 200 and eccentric mechanism 300 of the rhythm unit 10 of the rhythmic motor 10 in Figure 4. As shown in Figures 2 through 5, the drive mechanism 200 may include a motor assembly 210 and a pulley assembly 220. The motor assembly 210 includes a support 211 and a motor 212. The support 211 is disposed on the base 101 and includes a through hole 2111. The motor 212 is fixed to the support 211 and includes a drive shaft 2121, which protrudes from the through hole 2111 of the support 211. The pulley assembly 220 is disposed on the eccentric shaft 320 and driven by the motor assembly 210, and may include a bushing 221, a pulley 222, and a belt 223. The bushing 221 is fitted onto the drive shaft 2121. The pulley 222 is mounted on the eccentric mechanism 300 via screws and nuts. The belt 223 connects the bushing 221 and the pulley 222. When the motor 212 starts, the bushing 221 is driven to rotate by the drive shaft 2121 of the motor 212, simultaneously driving the belt 223, causing the pulley 222 to rotate and drive the eccentric mechanism 300. Furthermore, the buffer units 883 and 884 are each buffer pillars. Buffer unit 883 includes a top frame connecting part 885, and buffer unit 884 includes a top frame connecting part 886. Both top frame connecting parts 885 and 886 are directly connected to the top frame 500 and are made of soft rubber. In this way, the vibration motor 10 of the present invention can improve the stability of the structure and reduce the abnormal noise of the overall mechanism during operation, and can also reduce the load on the motor 212, thus reducing the power of the motor 212.

[0032] Furthermore, the eccentric mechanism 300 may further include two support seats 310. The two support seats 310 are disposed on the base 101, and each support seat 310 houses a bearing. An eccentric shaft 320 is pivotally mounted on the bearings of each support seat 310 and the bearing of the first transmission plate 410, and each support seat 310 is adjacent to and corresponds to an eccentric wheel 330. Specifically, both ends of the eccentric shaft 320 are threaded, and nuts are locked to the threads to position the first transmission plate 410 onto the eccentric shaft 320. Additionally, a pulley 222 is sleeved on the eccentric shaft 320, and a locating pin or screw is passed through the pulley 222 and the eccentric mechanism 300, causing the pulley 222 and the eccentric mechanism 300 to rotate synchronously. When the eccentric shaft 320 is driven to rotate by the pulley 222, one end of the first transmission plate 410 rotates eccentrically with the axis of the eccentric shaft 320 as the reference, and the other end of the first transmission plate 410 drives the first connecting shaft 420 to reciprocate along the first direction D1. One end of the second transmission plate 412 rotates eccentrically with the axis of the eccentric shaft 320 as the reference, and the other end of the second transmission plate 412 drives the second connecting shaft 422 to reciprocate along the third direction D3.

[0033] Please refer to Figures 2, 3, and 6, where Figure 6 is an exploded view of the transmission mechanism 400 of the rhythm unit 100 of the rhythmic motor 10 in Figure 4. As shown in Figures 2, 3, and 6, each first transmission component 430 of the transmission mechanism 400 may include two bearing seats 431, a first movable connecting plate 432, and two fixed seats 433. The two bearing seats 431 are disposed opposite to each other on the base 101. The body of the first movable connecting plate 432 is pivotally mounted between the two bearing seats 431, one end of the first movable connecting plate 432 is pivotally connected to the first connecting shaft 420, and the other end of the first movable connecting plate 432 is pivotally mounted between the two fixed seats 433. The two fixed seats 433 are fixed to the top frame 500. Specifically, each bearing seat 431 and each fixed seat 433 is provided with a bearing. This invention utilizes screws passing through bearings in the two bearing seats 431 and a first movable connecting plate 432, with the first movable connecting plate 432 directly connected to and surrounding the screws, meaning there are no bearings between the first movable connecting plate 432 and the screws. Similarly, this invention utilizes screws passing through bearings in the two fixed seats 433 and a first movable connecting plate 432, with the first movable connecting plate 432 directly connected to and surrounding the screws, again without bearings between the first movable connecting plate 432 and the screws. This allows the two bearing seats 431, the first movable connecting plate 432, and the two fixed seats 433 to move together, further reducing unnecessary components and significantly lowering manufacturing costs. Specifically, when the first connecting shaft 420 reciprocates along the first direction D1, one end of the first movable connecting plate 432 is driven by the first connecting shaft 420, and the first movable connecting plate 432 moves in a seesaw motion with the screw passing between the two bearing seats 431 as a fulcrum. The second fixed seat 433 is driven by the first movable connecting plate 432, and the top frame 500 is driven to make another reciprocating motion along the second direction D2.

[0034] Additionally, each second transmission component 440 of the transmission mechanism 400 may include two bearing seats 441, a second movable connecting plate 443, two connecting plates 444, and two fixed seats 445. The two bearing seats 441 are disposed opposite to each other on the base 101. The body of the second movable connecting plate 443 is pivotally mounted between the two bearing seats 441, and one end of the second movable connecting plate 443 is pivotally connected to the second connecting shaft 422. One end of each connecting plate 444 is pivotally connected to the other end of the second movable connecting plate 443. The two fixed seats 445 are fixed to the top frame 500 and provide pivot mounting for the other end of each connecting plate 444. Specifically, both the bearing seats 441 and the fixed seats 445 are provided with a bearing (not otherwise labeled). This invention utilizes a screw that passes through the bearings of the two bearing seats 441 and the second movable connecting plate 443, with the second movable connecting plate 443 directly connected to and surrounding the screw. There is no bearing between the second movable connecting plate 443 and the screw. Another screw passes through the second movable connecting plate 443 and the connecting plate 444, and yet another screw passes through the connecting plate 444 and the fixed seat 445. This allows the two bearing seats 441, the second movable connecting plate 443, the two connecting plates 444, and the two fixed seats 445 to move together, further reducing unnecessary components and significantly lowering manufacturing costs. Specifically, when the second connecting shaft 422 reciprocates along the third direction D3, one end of the second movable connecting plate 443 is driven by the second connecting shaft 422, and the second movable connecting plate 443 uses the screw passing between the two bearing seats 441 as a fulcrum, exhibiting another seesaw motion. The two fixed seats 433 are driven by the second movable connecting plate 443 and the two connecting plates 444, and drive the top frame 500 to make another reciprocating motion along the fourth direction D4.

[0035] Specifically, the first transmission assembly 430 and the second transmission assembly 440 are located between the first transmission plate 410 and the second transmission plate 412 in the direction of the eccentric shaft 320. There are two buffer units 883 and two buffer units 884, for a total of four buffer units 883 and 884. The two buffer units 883 are respectively adjacent to the two first transmission assemblies 430, and the two buffer units 883 are closer to the outside of the vibrating motor 10 than the two first transmission assemblies 430 in the direction of the eccentric shaft 320. The two buffer units 884 are respectively adjacent to the two second transmission assemblies 440, and the two second transmission assemblies 440 are closer to the outside of the vibrating motor 10 than the two buffer units 884 in the direction of the eccentric shaft 320. In other words, buffer units 883 and 884 are respectively provided near the two adjacent locations of each transmission mechanism 400; that is, buffer units 883 are provided near the first transmission assembly 430 of each transmission mechanism 400, and buffer units 884 are provided near the second transmission assembly 440 of each transmission mechanism 400. Therefore, in addition to being adjacent to the first transmission assembly 430 and the second transmission assembly 440 respectively, the buffer units 883 and 884 are also essentially located at the four corners of the vibrator 10, thus achieving both balanced buffering and reducing the size of the vibrator 10. In other embodiments, the buffer units are connected between the base and the top frame. The number of buffer units can be at least one. The buffer unit can be a column containing a spring, or it can be a block that is an elastic body as a whole. The location of the buffer units is not limited to the disclosure of this invention.

[0036] The buffer units 883 and 884 assist the top frame 500 in supporting the pressure, so as to reduce the torque of the drive mechanism 200, and improve the user's sense of impact during the reciprocating motion of the motor 10 through the buffer units 883 and 884.

[0037] Figure 7A is a front view schematic diagram illustrating the vertical (up and down) rhythmic state of the rhythmic unit 100 of the rhythmic motion device 10 in Figure 2. As shown in Figures 2 to 4 and Figure 7A, the length of the first movable connecting plate 432 is M1, and the length of the second movable connecting plate 443 is M2, which can satisfy the following condition: 0.5 ≤ M1 / M2 ≤ 2. Therefore, the first and second movable connecting plates can be designed to be of equal or unequal length, both achieving vertical and wave-like rhythmic movements. Thus, the rhythmic motion device of the present invention has design flexibility. In Figure 7A of this embodiment, the lengths M1 and M2 are equal, and the parameter M1 / M2 is 1.

[0038] The length of the second movable connecting plate 443 is M2, and the length of the second transmission plate 412 is M3, which can satisfy the following condition: 1.25 ≤ M2 / M3 ≤ 6. Therefore, the rhythmic motion of the present invention can realize vertical and wave-like rhythmic motions with various length-to-height ratios. Furthermore, the lengths M1, M2, and M3 mentioned in the present invention are all measured from the pivot of the element.

[0039] The first linkage shaft 420 and the second linkage shaft 422 may be unconnected and have the same axial direction (coaxial but not connected). In this way, the rhythm unit 100 in Figure 7A can achieve vertical rhythm.

[0040] At a given point in time during the reciprocating motion, the top frame 500 and the base 101 have a first distance L1 at the first transmission component 430 (e.g., at the fixed seat 433), and a second distance L2 at the second transmission component 440 (e.g., at the connecting plate 444). The first distance L1 and the second distance L2 can be equal. Therefore, the actuation mode of the rhythm unit 100 in Figure 7A is vertical rhythm. During the vertical rhythm, the eccentric shaft 320 performs eccentric motion. The eccentric shaft 320, through the first transmission plate 410, drives the first connecting shaft 420 to move vertically up and down linearly. The eccentric shaft 320, through the second transmission plate 412, drives the second connecting shaft 422 to move vertically up and down linearly. At any point in time during the reciprocating motion, the first movable connecting plate 432 and the second movable connecting plate 443 are mirror-symmetric with respect to the first connecting shaft 420 (or the second connecting shaft 422). The first direction D1, the second direction D2, the third direction D3, and the fourth direction D4 are all parallel to the up and down directions in Figure 7A. The first direction D1 is opposite to the second direction D2, the third direction D3 is opposite to the fourth direction D4, the first direction D1 is in the same direction as the third direction D3, the second direction D2 is in the same direction as the fourth direction D4, and the first distance L1 is equal to the second distance L2. That is, the top frame 500 vibrates vertically and linearly as a whole.

[0041] Figure 7B is a front view schematic diagram illustrating the wave-like rhythmic state of the rhythm unit 100 of the rhythmic motor 10 according to another embodiment of the present invention. The rhythm unit 100 in Figure 7A can be adjusted to become the rhythm unit 100 in Figure 7B. For example, the lengths of the first movable connecting plate 432 and the second movable connecting plate 443 of the rhythm unit 100 in Figure 7A can be shortened, and the present invention is not limited thereto. As shown in Figure 7B, the first connecting shaft 420 and the second connecting shaft 422 may not be connected. The first transmission plate 410 and the second transmission plate 412 are both pivotally connected to the eccentric shaft 320 and form a V-shape. Therefore, the rhythm unit 100 in Figure 7B can achieve wave-like rhythmic motion, further expanding the function and user experience of the rhythm unit 100.

[0042] The included angle A1 of the V-shape can be between 5 degrees and 30 degrees. This helps to improve the stability of wave-like vibrations and the user experience.

[0043] At a given point in time during the reciprocating motion, there is a first distance L1 between the top frame 500 and the base 101 at the first transmission component 430, and a second distance L2 between the top frame 500 and the base 101 at the second transmission component 440. The first distance L1 and the second distance L2 may not be equal. Therefore, the actuation mode of the rhythm unit 100 in Figure 7B is a wave-like rhythm. During the wave-like rhythm, the eccentric shaft 320 performs an eccentric motion. The eccentric shaft 320, through the first transmission plate 410, drives the first connecting shaft 420 to move vertically up and down linearly. The eccentric shaft 320, through the second transmission plate 412, drives the second connecting shaft 422 to move vertically up and down linearly. At any point in time during the reciprocating motion, the first direction D1, the second direction D2, the third direction D3, and the fourth direction D4 are all essentially parallel to the up and down directions in Figure 7B. The first direction D1 is opposite to the second direction D2, the third direction D3 is opposite to the fourth direction D4, the first direction D1 and the third direction D3 are in the same direction, and the second direction D2 and the fourth direction D4 are in the same direction. At one point in time during the reciprocating motion, the first movable connecting plate 432 and the second movable connecting plate 443 are not mirror-symmetric with respect to the first connecting shaft 420 (or the second connecting shaft 422), and the first distance L1 and the second distance L2 are not equal. At another point in time during the reciprocating motion, the first movable connecting plate 432 and the second movable connecting plate 443 are mirror-symmetric with respect to the first connecting shaft 420 (or the second connecting shaft 422), and the first distance L1 and the second distance L2 are equal. In other words, during the reciprocating motion, the top frame 500 in Figure 7B moves in a sequential cycle of eccentric motion of the eccentric shaft 320, with the left and right sides at equal height, left side higher than right side, left and right sides at equal height, and left side lower than right side, which means that the top frame 500 moves in a wave-like rhythm.

[0044] Figure 8 is a perspective view of the horizontal drive unit 800 of the rhythmic motion device 10 in Figure 2. As shown in Figures 2, 3, 7A, and 8, the rhythmic motion device 10 may further include a horizontal drive unit 800, which includes a horizontal drive motor 810, a horizontal drive wheel 820, and a horizontal eccentric rocker arm 830. The horizontal drive motor 810 is mounted on the top frame 500. The horizontal drive wheel 820 is coupled to the horizontal drive motor 810. One end of the horizontal eccentric rocker arm 830 is pivotally connected to the horizontal drive wheel 820, and the other end is pivotally connected to the base 101. The horizontal drive wheel 820 is driven to rotate by the horizontal drive motor 810, thereby driving the horizontal eccentric rocker arm 830 to cause the base 101 to vibrate horizontally. In this way, the rhythmic motion device 10 of the present invention can combine horizontal vibration with vertical rhythmic and / or wave-like rhythmic movements, further expanding the function and user experience of the rhythmic unit 100.

[0045] Specifically, the horizontal drive unit 800 may further include a torque-enhancing wheel 840, a belt 850, and a horizontal drive shaft 860. The torque-enhancing wheel 840 includes a first wheel portion (not shown) and a second wheel portion (not shown) coaxially. The diameter of the first wheel portion is larger than the diameter of the second wheel portion. The first wheel portion is coupled to the horizontal drive motor 810, and the second wheel portion is coupled to the horizontal drive wheel 820 through the belt 850. The horizontal drive shaft 860 is connected to the horizontal drive wheel 820. The horizontal eccentric rocker arm 830 is pivotally mounted on one end of the horizontal drive shaft 860. Thus, the horizontal eccentric rocker arm 830 can be eccentrically actuated to drive the base 101 to vibrate horizontally in the left-right direction in Figure 7A.

[0046] The horizontal drive unit 800 may further include a horizontal swing arm 870, which is pivotally connected to the base 101 and the horizontal eccentric rocker arm 830. Specifically, the horizontal eccentric rocker arm 830 is pivotally located between the two ends of the horizontal swing arm 870, with one end of the horizontal swing arm 870 disposed on the top frame 500 and the other end pivotally connected to the base 101, so that the horizontal drive unit 800 drives the base 101 to vibrate horizontally. The number of both the horizontal eccentric rocker arm 830 and the horizontal swing arm 870 may be two, and they are arranged in a mirror image.

[0047] In summary, this invention has the following advantages: First, when a user steps on or stands on the rhythmic motion device, it can generate a cyclical rhythm throughout the user's body, achieving periodic back-and-forth movement of various body parts. Second, by using the first and second connecting shafts to link the first and second transmission components, and simultaneously connecting and driving the top frame, the rhythmic motion device not only has a simple overall structure but also reduces unnecessary components, thereby greatly reducing manufacturing costs. Third, the rhythmic unit of this invention can be designed as either vertical up-and-down rhythmic motion or wave-like rhythmic motion, further expanding the functionality and user experience of the rhythmic motion device and providing design flexibility.

Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
