Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a 3D massage mechanism and a massage device with a 3D massage mechanism. Background Technology

[0002] With the increasing demand for health-related products, massage chairs, office massage chairs, gaming massage chairs, and other massage equipment are becoming increasingly popular. As the core component of these devices, the 3D massage mechanism's functional integration, size, massage stability, and user experience directly determine the product competitiveness of the massage equipment. However, existing 3D massage mechanisms still have many issues that need improvement, making it difficult to meet the market's demand for high-performance, miniaturized massage equipment. Specifically, these issues are reflected in the following aspects:

[0003] Existing 3D massage mechanisms often require separate push-out and swing-out drive mechanisms to achieve 3D massage functions such as push-out (i.e., switching between high and low positions of the massage components) and back-and-forth swinging. This results in redundant overall structure, numerous parts, and a large and thick mechanism, which not only hinders the miniaturization of massage devices but also increases storage difficulty, limiting their applicability, especially in space-constrained settings such as office chairs and lounge chairs. While some mechanisms attempt to integrate both functions, unreasonable layouts (such as placing the drive components and massage components on opposite sides) further exacerbate the bulky size problem.

[0004] The transmission mechanism design of existing massagers has flaws. On the one hand, the transmission components used to drive the oscillation or pushing motion are mostly single-stage transmissions, which make it difficult to balance torque and speed—either insufficient torque results in a soft massage intensity, or unstable speed causes the massage motion to become jerky. On the other hand, some transmission mechanisms do not use an appropriate gear ratio design, making it impossible to accurately adjust the power output according to massage needs, affecting the smoothness and consistency of the massage motion and reducing the user's massage experience.

[0005] Furthermore, the percussion function of existing massage mechanisms generally suffers from shortcomings in user experience. The eccentric shaft of their percussion mechanism often adopts a 180-degree eccentric angle design. When the percussion function ends and the massage components return to their original position, there is a significant height difference between the two massage balls, resulting in uneven force on the massage area and even abrupt jerking sensations. This seriously affects user comfort and has become a key bottleneck restricting the improvement of the massage experience.

[0006] Furthermore, the existing 3D massage mechanism's swing component lacks an effective balancing mechanism. During the back-and-forth swinging of the massage component, the two ends of the swing support mechanism are prone to offset or wobbling due to uneven force. This not only causes the massage trajectory to deviate from the preset path and reduces massage accuracy, but also accelerates the wear of internal components and shortens the lifespan of the mechanism. At the same time, the layout of the walking component and massage component in some mechanisms is misaligned, and the support balance of the dual walking mechanism is insufficient, causing the mechanism to easily jam or tilt when moving along the device track, further affecting the stability of the massage action.

[0007] Finally, existing 3D massage mechanisms have low space utilization. For example, the massage components are mostly assembled with the base in an externally suspended manner, and the massage components do not form an embedded fit with the base, making it difficult to reduce the overall height of the mechanism; moreover, the layout of the swing motor and transmission mechanism is mostly linear, which does not make full use of three-dimensional space, further compressing the optimization space for miniaturization of the mechanism. Utility Model Content

[0008] A primary objective of this invention is to provide a 3D massage mechanism and a massage device incorporating the mechanism. This invention aims to address the issues of bulky size and low functional integration in existing 3D massage mechanisms. By optimizing the embedded assembly of the base and massage components (the massage components pass through the base channel), the same-side layout of the swing component and the massage component, and the U-shaped three-dimensional arrangement of the swing motor and transmission mechanism, a high degree of integration of the mechanism's functions (pushing, swinging, walking, kneading, and pounding) is achieved. At the same time, the overall height and volume of the mechanism are significantly reduced, meeting the requirements for miniaturization and convenient storage of massage devices.

[0009] Another major objective of this invention is to provide a 3D massage mechanism and a massage device incorporating the mechanism, aiming to solve the problems of poor transmission stability and unbalanced power output in existing mechanisms. By configuring a multi-stage transmission gear set (including a first, second, and third transmission gear set, with gear ratios all less than 1) for the swing component, combined with a worm gear-type walking transmission mechanism and a kneading transmission mechanism, the rotation speed is precisely reduced and the transmission torque is effectively increased, ensuring smooth and uninterrupted massage movements (pushing, swinging, kneading), balancing massage intensity and movement consistency, and improving the reliability of the transmission system.

[0010] A core objective of this invention is to provide a 3D massage mechanism and a massage device incorporating the mechanism. Addressing the issue of poor massage experience in existing percussion functions, this invention replaces the traditional 180-degree eccentric angle with a 160-degree eccentric shaft in the percussion mechanism. This effectively avoids the height difference between the massage balls on both sides when the percussion function resets, eliminates the jerky feeling during massage, ensures even force distribution on the massaged areas, and significantly improves user massage comfort.

[0011] Another major objective of this utility model is to provide a 3D massage mechanism and a massage device with the mechanism, which solves the problems of insufficient balance and massage trajectory deviation in existing swing components. By adding a balancing mechanism (including an internal gear unit fixed to the base and an external gear unit fixed to the swing support mechanism) to the swing component, the movement trajectory of the swing support mechanism is restricted, the forces at both ends are balanced, deviation or shaking during the swing process is avoided, the massage trajectory is ensured to be accurate, and the wear of parts is reduced, thus extending the service life of the mechanism.

[0012] Another major objective of this invention is to provide a 3D massage mechanism and a massage device incorporating the mechanism, thereby optimizing the problem of low space utilization in existing mechanisms. By placing the walking component and the massage component on the same side of the base, partially embedding the massage component into the base channel, and using an upper and lower stacked design for the swing motor and transmission mechanism, the invention fully utilizes the three-dimensional space, reduces the overall thickness and volume of the mechanism, and provides support for the compact design of massage devices (such as office chairs and gaming chairs).

[0013] A major advantage of this invention is that it provides a 3D massage mechanism that integrates the swing component, massage component, and walking component on the same side. Combined with the embedded assembly of the massage component through the base channel, it achieves multi-functional integration of pushing, swinging, and walking while significantly reducing the overall size and height of the mechanism. This facilitates the miniaturization of massage devices and improves the ease of storage, thus resolving the contradiction of existing mechanisms being "large in size due to multiple functions".

[0014] Another advantage of this utility model is that it provides a 3D massage mechanism. Its swing component adopts a multi-stage transmission gear set (first to third transmission gear sets) and an appropriate gear ratio (all gear ratios are less than 1) design, which can accurately balance the transmission torque and speed, and ensure that the power of the swing motor is stably output after transmission. This avoids the massage intensity being too soft and prevents the movement from getting stuck, making the back-and-forth swing and high-low position switching of the massage component smoother and the intensity more uniform, thus improving the consistency and reliability of the massage movement.

[0015] Another advantage of this utility model is that it provides a 3D massage mechanism in which the eccentric shaft of the percussion mechanism adopts a 160-degree eccentric angle. Compared with the existing 180-degree eccentric design, it can completely solve the problem of the height difference of the massage balls on both sides when the percussion function is reset, avoid uneven force and jerking sensation in the massage area, significantly optimize the user's massage comfort, and break through the bottleneck of the existing percussion experience.

[0016] Another advantage of this utility model is that it provides a 3D massage mechanism in which the balancing mechanism (internal gear unit and external gear unit meshing) configured in the swing component can effectively balance the forces at both ends of the swing support mechanism, limit its movement trajectory, and ensure that the massage component swings back and forth without deviation or shaking. This not only improves the accuracy of the massage trajectory, but also reduces the wear of internal parts of the mechanism, extends the service life of the mechanism, and solves the defects of poor balance and easy wear of existing swing components.

[0017] A core advantage of this invention is that it provides a 3D massage mechanism whose walking component adopts a dual walking mechanism (a first active walking mechanism and a second passive walking mechanism) arranged on the same side and coplanar with the massage component. This not only improves the support and balance of the mechanism when it moves along the device track, avoiding movement jamming or tilting, but also further reduces the lateral volume of the mechanism. At the same time, the two-stage gear structure of the walking transmission mechanism can ensure stable power transmission, expand the massage coverage area, and take into account both movement stability and comprehensive massage.

[0018] Another advantage of this utility model is that it provides a 3D massage mechanism, in which the swing motor and swing transmission mechanism adopt a U-shaped structure with the upper and lower parts stacked, making full use of three-dimensional space, replacing the existing linear arrangement, and greatly improving the space utilization rate; at the same time, the massage push arm and the curved arm of the massage component are connected by a movable design of fixed bolts and elastic connecting units, which can adapt to the massage angle and the reverse force, further improving the massage comfort and adapting to the body curve needs of different users.

[0019] The final advantage of this utility model is that it provides a massage device (such as a massage chair, office chair, etc.) with a 3D massage mechanism. By incorporating the aforementioned 3D massage mechanism, it not only has the advantages of miniaturized and lightweight device design, but also achieves precise, stable, and comfortable 3D massage function, adapting to the needs of multiple usage scenarios such as office, leisure, and e-sports, thereby enhancing the product competitiveness of the massage device and solving the problem of existing massage devices where "function and size are difficult to balance".

[0040] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0041] Those skilled in the art should understand that, in the disclosure of this utility model, the terms longitudinal, transverse, up, down, front, back, left, right, vertical, horizontal, top, bottom, inside, outside, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0042] It is understood that the term "one" should be understood as at least one or more, that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. The term "one" should not be understood as a limitation on the number.

[0043] Refer to the accompanying drawings in this application specification. Figures 1 to 5 As shown, a 3D massage mechanism and a massage device incorporating a 3D massage mechanism according to a first preferred embodiment of this application are described below. The massage device includes a main unit and a 3D massage mechanism 100 disposed on the main unit. The massage device can be, but is not limited to, a massage chair, office chair, sofa chair, lounge chair, gaming chair, etc. The 3D massage mechanism includes a base 10, a massage component 20, a walking component 30, and a swing component 40 disposed on the base 10. The swing component 40 is connected to the massage component 20 and is used to drive the massage component 20 to switch between a low massage position and a high massage position to achieve the ejection function of the 3D massage mechanism. When the swing assembly 40 drives the massage assembly 20 from the low massage position to the high massage position, that is, the massage assembly 20 is pushed outward, the overall height of the 3D mechanism is increased, and the user of the massage device is pushed outward by the massage assembly 20; when the swing assembly 40 pulls the massage assembly 20 from the high massage position to the low massage position, that is, the massage assembly 20 returns to its original position inward, the overall height of the 3D mechanism is decreased, and the user of the massage device is supported inward by the massage assembly 20. The walking assembly 30 is disposed on one side of the base 10 and is disposed on the moving track of the device host. It is used to drive the base 10, the massage assembly 20 and the swing assembly 40 to move along the moving track of the device host, thereby realizing the displacement function of the 3D massage mechanism.

[0044] The base 10 includes a substrate body 11 and a channel 12 formed in the substrate body 11, wherein the channel 12 extends vertically through the substrate body 11, and the massage component 20 is disposed through the channel 12 of the base 10, and the massage component 20 moves vertically in the channel 12 when it moves between the massage low position and the massage high position.

[0045] It is understood that in this preferred embodiment of the present application, when the massage component 20 is in the massage low position, the massage component 20 is pulled by the swing component 40 toward the substrate body 11, and at least part of the massage component 20 passes through the channel 12 and moves to the other side of the substrate body 11, thereby reducing the overall height and size of the 3D massage mechanism, which is beneficial for storage and retrieval.

[0046] It is worth mentioning that, in this preferred embodiment of the present application, the massage component 20 is movably disposed in the channel 12 of the base 10, which can reduce the overall height and volume of the 3D massage mechanism and facilitate the miniaturization of the device.

[0047] like Figure 2 and Figure 3 As shown, the walking assembly 30 includes a walking motor 31, a walking transmission mechanism 32, a first walking mechanism 33, and a second walking mechanism 34. The first walking mechanism 33 and the second walking mechanism 34 are spaced apart and arranged on one side of the base 10, supporting the movement of the base 10, the massage assembly 20, and the swing assembly 40. The walking motor 31 is connected to the first walking mechanism 33 via the walking transmission mechanism 32, and the walking motor 31 drives the connected first walking mechanism 33 to move via the walking transmission mechanism 32. It is understood that in this preferred embodiment of the present application, the first walking mechanism 33 is implemented as an active walking mechanism, and the second walking mechanism 34 is a passive walking mechanism.

[0048] Specifically, the walking motor 31 is fixed to one side of the base 10, wherein the first walking mechanism 33 and the second walking mechanism 34 of the walking assembly 30 are on the same side as the massage assembly 20, which helps to reduce the overall volume of the 3D massage mechanism. It is understood that the walking assembly 30 and the massage assembly 20 are located on the same side of the base 10, and at least a portion of the structure of the massage assembly 20 is embedded within the channel 12 of the base 10, thereby reducing the overall thickness of the 3D massage mechanism and facilitating its miniaturization.

[0049] The walking transmission mechanism 32 of the walking assembly 30 is implemented as a worm gear mechanism, wherein the walking transmission mechanism 32 drives the massage assembly 20 connected thereto to move. The first walking mechanism 33 includes a first walking shaft 331, a first walking support wheel 332 disposed on the first walking shaft 331, and an active walking wheel 333 located inside the first walking support wheel 332, wherein the first walking support wheel 332 and the active walking wheel 333 are supported by the first walking shaft 331. The first walking shaft 331 of the first walking mechanism 33 meshes with the walking transmission mechanism 32, the walking transmission mechanism 32 drives the first walking shaft 331 to rotate, and the first walking shaft 331 drives the active walking wheel 333 to rotate. It is worth mentioning that, in this preferred embodiment of the present application, the active walking wheel 333 is implemented as a gear, which meshes with the track of the device host.

[0050] The second walking mechanism 34 includes a second walking shaft 341 and a second walking support wheel 342 disposed on the second walking shaft 341, wherein the second walking shaft 341 and the second walking support wheel 342 of the second walking mechanism 34 are supported at the other end of the base plate 10, and the first walking mechanism 33 and the second walking mechanism 34 are disposed on opposite sides of the massage assembly 20.

[0051] The walking motor 31 is fixed to one side of the base 10 and connected to the first walking mechanism 33 via the walking transmission mechanism 32, driving its movement. The turbine of the walking transmission mechanism 32 adopts a two-stage gear structure, which can effectively adjust torque and speed to ensure stable power transmission. The first walking mechanism 33, as the active walking mechanism, has a first walking support wheel 332 and an active walking wheel 333 on its first walking shaft 331. The active walking wheel 333 is a gear structure that meshes with the track of the main unit of the device. When the walking motor 31 is driven, the power is transmitted to the first walking shaft 331 through the transmission mechanism, thereby driving the active walking wheel 333 to rotate, realizing the movement of the massage mechanism on the track of the main unit of the device, and expanding the massage coverage area.

[0052] The second traveling mechanism 34 includes a second traveling shaft 341 and a second traveling support wheel 342, which are spaced apart from the first traveling mechanism 33 and arranged on one side of the base 10, jointly supporting the movement of the base 10, the massage component 20, and the swing component 40. This dual traveling mechanism design improves the stability and balance of the movement, ensuring smooth and stable movement under different working conditions and equipment usage environments, and avoiding problems such as movement shaking or deviation caused by uneven force on one side or insufficient support.

[0053] like Figure 2 and Figure 4As shown, the swing component 40 is disposed on the same side as the kneading mechanism 22 and the pounding mechanism 23 of the massage component 20. The swing component 40 drives the massage component to rotate through the second walking shaft 341 of the walking component 30. The massage component 20 rotates along the axial direction of the first walking shaft 331, thereby realizing the back-and-forth swing function of the massage component 20.

[0054] The swing assembly 40 includes a swing motor 41, a swing transmission mechanism 42, and a swing support mechanism 43, wherein the swing transmission mechanism 42 is connected to the swing motor 41, and the second traveling shaft 341 is connected to the swing support mechanism 43. When the swing motor 41 drives the swing support mechanism 43 to rotate via the swing transmission mechanism 42, the swing support mechanism 43, supported by the second traveling shaft 341, pushes the base 10 and the massage assembly 20 to rotate in a specific direction and angle, thereby realizing the back-and-forth swing of the massage assembly 20. In other words, the second traveling shaft 341 drives the connected swing support mechanism 43 to move in a specific direction, thereby causing the massage assembly 20 to extend and retract.

[0055] Specifically, the swing support mechanism 43 is pivotally mounted on one side of the base 10, wherein the swing support mechanism 43 is connected to the swing assembly 40, and the swing assembly 40 can drive the swing support mechanism 43 to rotate in a specific direction and angle to realize the back-and-forth swing of the 3D massage mechanism. The second travel shaft 341 is fixedly mounted at both ends of the swing support mechanism 43, wherein the second travel shaft 341 of the second travel mechanism 34 provides a supporting force for the swing support mechanism 43. When the swing motor 41 of the swing assembly 40 drives the swing support mechanism 43 to rotate through the swing transmission mechanism 42, the swing support mechanism 43 is subjected to the reverse force of the second travel shaft 341, which in turn pushes the base 10 and the massage assembly 20 mounted on the base 10 to rotate in a specific direction and angle.

[0056] It is understood that when the swing assembly 40 drives the swing support mechanism 43 to move outward, that is, when the swing support mechanism 43 is pushed to move away from the base 10, one end of the base 10 and the massage assembly 20 supported by the base 10 will rotate outward in a specific direction and angle, that is, the massage arm 21 of the massage assembly 20 extends outward; when the swing assembly 40 drives the swing support mechanism 43 to move in the opposite direction, that is, when the swing support mechanism 43 is pushed to move towards the base 10, one end of the base 10 and the massage assembly 20 supported by the base 10 will rotate inward in a specific direction and angle, that is, the massage arm 21 of the massage assembly 20 retracts inward.

[0057] like Figure 2 As shown, the swing motor 41 of the swing assembly 40 is connected to the swing transmission mechanism 42, wherein the swing transmission mechanism 42 includes a transmission gear set 421 and a transmission push rod mechanism 422 connected to the transmission gear set 421. The transmission gear set 421 is tractably connected to the swing motor 41 and the transmission push rod mechanism 422, and the swing motor 41 drives the transmission push rod mechanism 422 to move through the transmission gear set 421. One end of the transmission push rod mechanism 422 is connected to the transmission gear set 421, and the other end of the transmission push rod mechanism 422 is connected to the swing support mechanism 43. When the swing motor 41 drives the transmission gear set 421 to move, the transmission push rod mechanism 422 pushes the swing support mechanism 43 to rotate in a specific direction and angle.

[0058] In this preferred embodiment of the present application, the swing motor 41 and the swing transmission mechanism 42 of the swing assembly 40 are stacked vertically, that is, the swing motor 41 and the swing transmission mechanism 42 are located on the same side of the swing support mechanism 43. Preferably, the swing motor 41 and the swing transmission mechanism 42 of the swing assembly 40 have a U-shaped structure, which helps to save space.

[0059] Let the axial direction of the swing motor 41 be the X-axis direction, that is, the swing motor 41 extends along the X-axis direction. The direction of the transmission push rod mechanism 422 is parallel to the direction of the swing motor 41, that is, the axial direction of the transmission push rod mechanism 422 is parallel to the X-axis direction. The direction of the transmission gear set 421 is perpendicular to the direction of the swing motor 41, that is, the direction of the transmission gear set 421 is the Y-axis direction.

[0060] The transmission gear set 421 is implemented as a multi-stage transmission assembly, wherein the transmission gear set 421 includes a first transmission gear set 4211, a second transmission gear set 4212 and a third transmission gear set 4213, and the second transmission gear set 4212 is tractably connected between the first transmission gear set 4211 and the third transmission gear set 4213, that is, the first transmission gear set 4211 transmits kinetic energy to the third transmission gear set 4213 through the second transmission gear set 4212.

[0061] The first transmission gear set 4211 is connected to the swing motor 41, and the swing motor 41 drives the first transmission gear set 4211 to move. The third transmission gear set 4213 is connected to the telescopic rod assembly 20, and the third transmission gear set 4213 drives the transmission push rod mechanism 422 to move, that is, the third transmission gear set 4213 drives the transmission push rod mechanism 422 to reciprocate and extend along its axial direction.

[0062] In this preferred embodiment of the present application, the transmission gear set 421 is a multi-stage transmission assembly. Through the multi-stage transmission of the transmission gear set 421, the rotation of the swing motor 41 can be converted into kinetic energy suitable for driving the telescopic rod assembly 20. In short, in this application, the first transmission gear set 4211, the second transmission gear set 4212, and the third transmission gear set 4213 of the transmission gear set 421 drive the movement according to a specific transmission ratio and transmission speed.

[0063] It is worth mentioning that, in this preferred embodiment of the present application, the first transmission gear set 4211, the second transmission gear set 4212, and the third transmission gear set 4213 of the transmission gear set 421 are mutually meshing gear sets.

[0064] The first transmission gear set 4211 includes a first gear and a second gear meshing with each other; the second transmission gear set 4212 includes a third gear and a fourth gear meshing with each other; and the third transmission gear set 4213 includes a fifth gear and a sixth gear meshing with each other. The first gear is connected to the transmission shaft of the oscillating motor 41, and the oscillating motor 41 drives the first gear to rotate synchronously. The second gear and the third gear are coaxially arranged, meaning the first gear drives the third gear to rotate through the second gear meshing with it. The fourth gear and the fifth gear are coaxially arranged, meaning the third gear drives the fifth gear to rotate through the fourth gear meshing with it. The sixth gear is coaxially arranged with the transmission push rod mechanism 422, meaning the sixth gear is driven and drives the transmission push rod mechanism 422 connected to it to rotate.

[0065] In this preferred embodiment of the present application, the gear ratio of the first transmission gear set 4211 of the transmission gear set 421 is less than 1, the gear ratio of the second transmission gear set 4212 is less than 1, and the gear ratio of the third transmission gear set 4213 is less than 1. By using the first transmission gear set 4211, the second transmission gear set 421, and the third transmission gear set 4213 of the transmission gear set 421, the rotational speed is reduced and the transmission torque is increased.

[0066] like Figure 4 As shown, the transmission push rod mechanism 422 includes a push rod base 4221, a transmission screw 4222 disposed on the push rod base 4221, and a push rod 4223 connected to the transmission screw 4222. One end of the transmission screw 4222 is connected to the transmission gear set 421, and the other end of the transmission screw 4222 is connected to the push rod 4223. The transmission screw 4222 is driven to rotate by the transmission gear set 421, and the transmission screw 4222 drives the push rod 4223, which meshes with it, to move back and forth along its axial direction. In turn, the push rod 4223 pushes the swing support mechanism 43 connected to it to move.

[0067] The push rod 4223 further includes a nut that meshes with the transmission screw 4222 and a push rod unit, wherein the push rod unit is connected to the nut, and the nut drives the push rod unit to move synchronously. It is worth mentioning that, in this preferred embodiment of the present application, the push rod unit is pivotally connected to the swing support mechanism 43, and the push rod unit can push the swing support mechanism 43 to rotate in a specific direction.

[0068] The swing support mechanism 43 further includes at least one pivot support unit 431 and a linkage mechanism 432 connected to the pivot support unit 431. One end of the pivot support unit 431 is pivotally connected to the base plate 10, and the other end of the pivot support unit 431 is pivotally connected to the linkage mechanism 432. When the swing transmission mechanism 42 pushes the linkage mechanism 432 of the swing support mechanism 43, the linkage mechanism 432 rotates in a specific direction under the support of the pivot support unit 431. The pivot support unit 431 of the swing support mechanism 43 is disposed at both ends of the linkage mechanism 432.

[0069] The swing assembly 40 further includes a balancing mechanism 44, wherein the balancing mechanism 44 is fixed to the base 10 and is disposed on the opposite side to the swing transmission mechanism 42. The balancing mechanism 44 is used to balance the force received by the swing support mechanism 43 and prevent the swing support mechanism 43 from being subjected to unbalanced forces at both ends.

[0070] The balancing mechanism 44 includes an internal gear unit fixed to the base and an external gear unit fixed to the swing support mechanism 43, wherein the internal gear unit and the external gear unit mesh with each other. When the swing support mechanism 43 is pushed, the balancing mechanism 44 restricts the movement trajectory of the swing support mechanism 43 to maintain motion balance.

[0071] like Figure 2 As shown, the massage assembly 20 includes two massage arms 21, a kneading mechanism 22 and a percussion mechanism 23 connected to the massage arms 21, wherein the massage arms 21 are arranged at intervals on both sides of the kneading mechanism 22 and the percussion mechanism 23. The kneading mechanism 22 drives the massage arms 21 to perform kneading action by swinging left and right; the percussion mechanism 23 drives the massage arms 21 to perform percussion action by vibrating back and forth.

[0072] The kneading mechanism 22 includes a kneading motor 221, a kneading transmission mechanism 222, and a kneading eccentric shaft 223. The kneading transmission mechanism 222 is tractably connected between the kneading motor 221 and the kneading eccentric shaft 223. The kneading motor 221 drives the kneading eccentric shaft 223 to rotate via the kneading transmission mechanism 222. The massage arms 21 are disposed on both sides of the kneading eccentric shaft 223. When the kneading eccentric shaft 223 rotates, it drives the massage arms 21 connected to it to move in an eccentric manner, thereby realizing the adjustment of the kneading function width.

[0073] The kneading transmission mechanism 222 is implemented as a worm gear mechanism, that is, the kneading motor 221 is connected to the kneading eccentric shaft 223 through a worm gear. Preferably, in this preferred embodiment of the application, the kneading motor 221 is implemented as a brushless motor.

[0074] The massage assembly 20 includes two massage arms 21, and a kneading mechanism 22 and a percussion mechanism 23 connected to them. The massage arms 21 are distributed on both sides of the kneading mechanism 22 and the percussion mechanism 23, forming a stable structural layout. The kneading motor 221 in the kneading mechanism 22 drives the kneading eccentric shaft 223 to rotate through a worm gear mechanism (kneading transmission mechanism 222). When the kneading eccentric shaft 223 rotates, the massage arms 21 move in an eccentric manner, realizing precise adjustment of the kneading function width.

[0075] When the kneading motor 221 starts, its rotational motion is transmitted to the gears via a worm gear, which in turn drives the kneading eccentric shaft to rotate. Due to the special structure of the eccentric shaft, the massage arms mounted on both sides of it swing eccentrically. During this process, the curved arms of the massage arms drive the massage push arms, and the massage balls at the ends of the push arms reciprocate along a specific curved trajectory, thereby achieving a kneading action on the human muscles. By precisely controlling the speed of the kneading motor and the transmission ratio between the worm gear and the gears, the frequency and intensity of the kneading can be adjusted to meet the needs of different users.

[0076] The percussion mechanism 23 includes a percussion motor 231, a percussion transmission mechanism 232, and a percussion connection mechanism 233. The percussion transmission mechanism 232 is tractably connected between the percussion motor 231 and the percussion connection mechanism 233. The percussion connection mechanism 233 is connected to the massage arm 21. When the percussion motor 231 drives the percussion connection mechanism 233 to move through the percussion transmission mechanism 232, the percussion connection mechanism 233 rotates rapidly eccentrically and drives the massage arm 21 to move in a vibrating manner to realize the percussion action.

[0077] As an example, in a specific example of this application, the striking transmission mechanism 232 is implemented as a belt drive device consisting of a belt and a pulley, wherein the striking motor 231 drives the striking connecting mechanism 233 to move through the belt drive device. It is understood that the belt drive device includes a transmission belt 2321 and a pulley 2322. The striking motor 231 drives the pulley 2322 to rotate through the transmission belt 2321, thereby driving the striking connecting mechanism 233 to move. The striking eccentric shaft 2331 of the striking connecting mechanism 233 has an eccentric unit at its end, connected to the vibration connecting unit 2332. When the striking eccentric shaft 2331 rotates, it drives the vibration connecting unit 2332 to vibrate, thereby enabling the massage arm 21 to perform a striking action. Unlike the 180-degree eccentric angle in the prior art, this utility model adopts a 160-degree eccentric angle, effectively avoiding the problem of a large height difference between the massage balls on both sides when the striking function of the mechanism ends, significantly improving the user's massage comfort.

[0078] The striking transmission mechanism 232 further includes a transmission belt 2321 and a pulley 2322, wherein the pulley 2322 is coaxially arranged with the striking connection mechanism 233, the transmission belt 2321 is connected to the striking motor 231, the striking motor 231 drives the pulley 2322 to rotate through the transmission belt 2321, and the striking connection mechanism 233 rotates synchronously with the pulley 2322.

[0079] The striking connection mechanism 233 further includes a striking eccentric shaft 2331 and a vibration connection unit 2332, wherein the vibration connection unit 2332 is connected between the striking eccentric shaft 2331 and the massage arm 21. The end of the striking eccentric shaft 2331 is provided with an eccentric unit, and the vibration connection unit 2332 is tractably connected to the eccentric unit of the striking eccentric shaft 2331. When the striking eccentric shaft 2331 of the striking connection mechanism 233 rotates, the striking eccentric shaft 2331 rotates rapidly eccentrically and drives the vibration connection unit 2332 connected to it to move in a vibrating manner, thereby driving the massage arm 21 to perform a striking action by the vibration connection unit 2332.

[0080] It is worth mentioning that the existing technology uses a 180-degree eccentricity in the percussion mechanism, resulting in a large height difference between the massage balls on both sides of the mechanism after the percussion function ends, leading to a poor customer experience. In this preferred embodiment of the application, the percussion connecting mechanism 233 has a 160-degree eccentricity, which can effectively prevent the problem of a large height difference between the massage arms 21 on both sides of the mechanism. Preferably, in this preferred embodiment of the application, the percussion motor 231 is a brushless motor.

[0081] The massage arm 21 includes a curved arm 211, a massage push arm 212, and at least one massage ball 213 disposed on the massage push arm 212. The curved arm 211 and the massage push arm 212 are connected. The curved arm 211 drives the massage push arm 212 to rotate eccentrically. The massage push arm 212 is driven by the curved arm 211, and the massage ball 213 reciprocates along a specific motion curve at the end of the massage push arm 212 to achieve kneading massage and percussion massage.

[0082] The massage push arm 212 and the curved arm 211 are movably connected. The curved arm 211 can drive the massage push arm 212 to move. When the massage push arm 212 is subjected to a reverse force, the massage push arm 212 can rotate along the movable connection point to improve the comfort of the massage and adapt to different massage angles.

[0083] In a specific example of this application, the massage arm 21 is a movable arm structure, wherein the movable arm can rotate about a fixed point and is limited by a tension spring. Accordingly, the massage arm 21 further includes a connecting unit 214, wherein the connecting unit 214 is used to connect the curved arm 211 and the massage push arm 212, wherein the connecting unit 214 further includes a fixing bolt and an elastic connecting unit, wherein the fixing bolt connects the massage push arm 212 and the curved arm 211 in a point-fixed manner, the massage push arm 212 can rotate along the fixing bolt, and the elastic connecting unit elastically connects the massage push arm 212 and the curved arm 211 based on the pre-tightening force of the massage push arm 212. It is worth mentioning that, in this preferred embodiment of this application, the elastic connecting unit is implemented as an elastic element such as a tension spring or a spring.

[0084] Optionally, in another optional embodiment of this application, the massage arm 21 is a fixed arm, that is, the curved arm 211 and the massage push arm 212 of the massage arm 21 are fixedly connected. It is understood that, compared to a movable arm, the fixed arm structure allows the massage ball to massage the corresponding acupoints more precisely; compared to the flexibility of a movable arm, the fixed arm has higher precision.

[0085] It is worth mentioning that the curved arm 211 drives the massage push arm 212 to rotate eccentrically, and the massage ball 213 at the end of the massage push arm 212 reciprocates along a specific motion curve to achieve kneading and percussion massage. The massage push arm 212 and the curved arm 211 are movably connected by a connecting unit 214, which includes a fixing bolt and a tension spring (elastic connection unit). The fixing bolt provides point fixation, allowing the massage push arm 212 to rotate along it, while the tension spring provides elastic connection. When the massage push arm 212 is subjected to a reverse force, it can rotate along the movable connection point, effectively improving the adaptability and comfort of the massage, and better conforming to the curves of the human body and the needs of different massage angles.

[0086] The swing component 40 can push the massage component 20 to move back and forth along the channel 12 of the base 10, thereby realizing the ejection function of the 3D massage mechanism.
