Description

Technical Field

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

[0002] With the upgrading of consumption and the increasing demand for health, massage functions are gradually penetrating from traditional large massage chairs to miniaturized, scenario-based devices. Products such as gaming chairs, car massage devices, office lounge sofas, and small home massage cushions are integrating massage modules to meet users' immediate relaxation needs in work, travel, and entertainment scenarios. However, these small massage devices place stringent requirements on the size, thickness, and adaptability of the core component, namely the massage mechanism. Existing massage mechanisms generally suffer from bottlenecks that are difficult to overcome, severely restricting the development and experience upgrade of small massage devices.

[0003] First, the overall size of existing massage mechanisms is too large, especially in the thickness direction. Most traditional mechanisms are over 50mm thick, and some even exceed 80mm, making it impossible to embed them into the thin seat cushions or backrest structures of smaller devices. Even with some manufacturers introducing so-called miniaturized mechanisms, their length and width are still difficult to fit into the compact internal space of devices. For example, the interior space reserved inside the seat back of a car massager is limited, and an oversized mechanism will compress the seat foam layer, resulting in a decrease in user comfort. Gaming chairs, in order to ensure wrap-around comfort and support, have an internal structure that includes a frame, adjustment components, etc. A large-sized mechanism is prone to space conflicts with these components, forcing manufacturers to simplify seat functions or increase seat size, which goes against the original intention of miniaturization design.

[0004] Secondly, existing small-sized massage mechanisms often simplify the massage arm structure to control size, employing a rigid, fixed design that lacks adaptive adjustment capabilities. These rigid massage arms cannot conform to the natural curves of the neck, waist, and back, leading to concentrated pressure in certain areas during massage. This can result in a harsh feel or even muscle soreness and discomfort. Furthermore, because they cannot automatically adjust the angle and intensity based on the user's body shape, weight, or massage area, users must frequently manually adjust the device to find suitable massage points, making operation cumbersome—especially in in-vehicle settings, where manual adjustment also poses safety hazards. In addition, rigid massage arms lack a cushioning mechanism, resulting in strong impact when the massage balls contact the body. Prolonged use can easily cause component wear and tear, potentially reducing user engagement.

[0005] Furthermore, the current mechanism's component layout and transmission design are unreasonable, further exacerbating size and user experience issues. The walking and massage components are often stacked on a single side, with the motor, transmission mechanism, eccentric shaft, and other components concentrated on the same side of the base. This results in a cumulative dimension in the height direction of the mechanism, making it difficult to achieve a slim profile. The walking component often uses a structure where the motor and walking shaft are vertically connected, which not only occupies a large lateral space but also easily leads to unstable power transmission due to transmission gaps. This causes the mechanism to jam and wobble when moving on the track, affecting the accuracy of the massage coverage. Some small-sized mechanisms even omit the walking function altogether, only providing point-to-point massage, failing to meet users' needs for massaging large areas such as the back and waist.

[0006] Furthermore, existing small-sized massage mechanisms have low functional integration, with most only supporting single kneading or percussion functions, making it difficult to simulate the complex techniques of professional massage therapists, and they also operate at high noise levels. In environments where quietness is crucial, such as offices and vehicles, noise can severely impact the user experience. These shortcomings in size, adaptability, functionality, and user experience mean that existing massage mechanisms cannot meet the technical requirements of small massage devices, necessitating a new type of mechanism that truly achieves thinness, high adaptability, and adaptive massage functionality to overcome industry bottlenecks. Utility Model Content

[0007] This invention aims to overcome the technical defects of existing massage mechanisms in the field of massage technology, such as poor size adaptability, insufficient massage adaptability, redundant structural layout and lack of transmission stability, and provides a small massage mechanism and a massage device with the small massage mechanism.

[0008] One utility model objective is to provide a miniaturized and thinner massage mechanism, solving the problem that existing massage mechanisms are too large in thickness, length, and width, making them unsuitable for installation in small massage devices such as gaming chairs, car massage devices, office chairs, and small massage sofas. By providing a mounting channel running through the front and back of the base, at least a portion of the massage and walking components are passed through the base and fixed to the front and back of the base respectively. This avoids the high redundancy caused by stacking components on one side, reducing the overall size of the mechanism and allowing it to be embedded in the limited internal space of small massage devices. This prevents structural conflicts or encroachment on user space caused by an excessively large mechanism.

[0009] One utility model objective is to provide a small massage mechanism that addresses the problem that existing small-sized massage mechanisms often have rigid massage arms lacking adaptive functionality, by providing the massage arms with adaptive adjustment capabilities for angle and intensity. Through the design of a movable connection structure for the massage arms (such as using connecting bolts to achieve a point-fixed connection between the curved arm and the massage push arm, and using elastic connection units such as tension springs to provide pre-tension), the massage push arm can rotate along the connection point. This allows it to automatically adjust its posture according to the user's body shape, the natural curve of the massage area, and the force applied, avoiding concentrated local force or excessive impact, reducing manual adjustment operations, and improving massage comfort and fit.

[0010] One utility model objective is to provide a small massage mechanism that optimizes the component layout and transmission structure, improving space utilization and power transmission stability. Addressing the issues of large lateral space occupation and transmission jamming caused by the vertical connection of the motor and the walking shaft in existing walking components, the walking component is designed with a U-shaped transmission structure (the axis of the walking motor is parallel to the axis of the first walking shaft, and the walking transmission mechanism is perpendicular to both axes). A double worm gear transmission mechanism is employed to achieve a large reduction ratio and reliable self-locking within a compact space, ensuring stable power transmission from the walking motor to the walking mechanism, driving the massage mechanism to move smoothly and steadily along the equipment track, expanding the massage coverage area. Simultaneously, the base mounting slot accommodates the percussion mechanism, further reducing the height dimension of the massage mechanism.

[0011] One utility model objective is to provide a small massage mechanism that, while achieving miniaturization, ensures functional integration and quiet operation. By rationally arranging the kneading mechanism (including a kneading motor, a two-stage worm gear-gear transmission mechanism, and a kneading eccentric shaft) and the percussion mechanism (including a percussion motor, a belt drive mechanism, and a percussion eccentric shaft assembly), the mechanism simultaneously provides a combined kneading and percussion massage function, simulating professional massage techniques. Furthermore, by optimizing the precision of the transmission components, operating noise is reduced, making it suitable for environments with high quietness requirements, such as offices and vehicles.

[0012] One utility model objective is to provide a miniature massage mechanism that improves installation stability and structural compactness. Using a base as a unified support carrier for the massage and walking components, a through-type installation and front / back fixing method enhances the connection stability between the components and the base, preventing structural loosening caused by scattered component installation. Simultaneously, unnecessary structural redundancy is reduced, ensuring reliable mechanical properties while maintaining miniaturization, meeting long-term use requirements. A major advantage of this utility model is that it provides a... Another advantage of this invention is that it provides a small massage mechanism and a massage device with the small massage mechanism. This invention effectively overcomes the shortcomings of existing massage mechanisms in terms of size compatibility, massage experience, transmission stability, and functional integration. Specific advantages are as follows: This invention significantly achieves miniaturization and thinning of the massage mechanism, efficiently adapting to the installation needs of small massage devices in various scenarios. By setting an installation channel running through the front and back of the base, and opening an installation groove on the back of the base, the core structures of the massage component and the walking component adopt a layout that runs through the base and is fixed on multiple sides. For example, the kneading mechanism in the massage component is fixed to the front of the base, the percussion mechanism is embedded in the installation groove on the back of the base and partially extends through the installation channel to the front, the walking motor in the walking component is fixed to the back of the base, and the first walking mechanism and the second walking mechanism are spaced apart on the front of the base, avoiding the high redundancy problem caused by single-sided stacking of components in the prior art. At the same time, the walking component innovatively adopts a U-shaped transmission structure, keeping the axis of the walking motor parallel to the axis of the first walking shaft, and the walking transmission mechanism perpendicular to both axes, effectively solving the problem of excessive lateral space occupied by the traditional vertical connection of the motor and walking shaft. The above design significantly reduces the overall size of the mechanism in terms of thickness, length and width, allowing it to be smoothly embedded in the limited internal space of small massage devices such as gaming chairs, car massage devices, and office chairs. This avoids internal structural conflicts or encroachment on the user's space and breaks through the technical bottleneck of existing small-sized mechanisms that are difficult to balance size and performance.

[0013] This invention endows the massage arm with adaptive adjustment capabilities, significantly improving massage comfort and body fit. Addressing the shortcomings of existing small-sized massage mechanisms where the massage arms are mostly rigid and fixed structures, unable to conform to the body's curves, this invention designs the massage arm with a movable connection structure: a connecting unit connects the curved arm and the massage push arm. The connecting unit includes connecting bolts and elastic elements such as tension springs. The connecting bolts provide point fixation, while the elastic elements provide preload, allowing the massage push arm to rotate flexibly along the connecting bolts. When the massage balls at the end of the massage arm contact the neck, waist, back, or other areas of the body, the massage push arm automatically adjusts its angle and massage intensity according to the user's body curves and the pressure applied to the massaged area. This avoids problems such as concentrated localized force and excessive impact caused by rigid structures, and reduces the number of steps required for manual adjustment, making it particularly suitable for scenarios where manual adjustment is inconvenient, such as in vehicles. This upgrades the massage mechanism from passively adapting to the body to actively conforming to it, enhancing the user experience.

[0014] This invention optimizes the walking transmission system, ensuring stable power transmission and a wide massage coverage area. The walking component adopts a double worm gear transmission mechanism. Through the linkage of the first and second worm gears, a large reduction ratio and reliable self-locking function are achieved in a compact space. Compared with the existing single-stage transmission structure, the power transmission is more stable, the operating noise is lower, and it can effectively prevent the massage mechanism from sliding on the inclined equipment track. At the same time, the U-shaped transmission structure layout design not only reduces the lateral space occupied, but also avoids the jamming and shaking problems caused by transmission gaps in traditional vertical connection methods. With the dual support design of the active and passive walking mechanisms, the active walking mechanism is equipped with gear-type active walking wheels that can precisely mesh with the equipment track, while the passive walking mechanism provides auxiliary support, enabling the massage mechanism to move smoothly and stably along the equipment track, effectively expanding the massage coverage area and solving the limitation of some small-sized massage mechanisms that can only achieve fixed-point massage due to the omission of the walking function.

[0015] This invention achieves miniaturization while maintaining a high degree of integration of massage functions and quiet operation, making it suitable for various usage scenarios. Through a rational structural layout, the massage component integrates two core massage functions: kneading and percussion. The kneading mechanism uses a two-stage transmission structure of worm gears and gears to drive the massage arms to achieve precise kneading by swinging left and right. The percussion mechanism drives the eccentric shaft to rotate via belt transmission, causing the massage arms to vibrate back and forth to achieve gentle percussion, simulating the combined massage techniques of a professional masseuse. Compared to existing single-function small-sized mechanisms, this provides a richer massage experience. Furthermore, by optimizing the precision of the transmission components, such as controlling the meshing gap of the double worm gears, adjusting the belt tension, and embedding the percussion mechanism into the base mounting groove to reduce vibration transmission, the noise level of the mechanism is effectively reduced. This makes it suitable for scenarios with high requirements for quiet operation, such as offices and vehicles, overcoming the technical pain point of high noise in small-sized mechanisms.

[0016] This invention possesses excellent structural stability and reliable mechanical properties, meeting the demands of long-term, high-frequency use. Using a base as a unified support carrier for both the massage and walking components, a through-type installation and faceted fixing method ensures a more stable connection between each component and the base, avoiding the structural looseness and uneven stress problems caused by dispersed component installation in existing technologies. Furthermore, the elastic connecting unit of the massage arm buffers the impact force during massage, reducing component wear; the dual-walking mechanism of the walking component provides balanced support to the base, preventing structural deformation caused by unilateral force during movement. These designs ensure that the mechanism maintains good structural strength and mechanical stability while achieving miniaturization and thinness, extending the product's service life.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] Refer to the accompanying drawings in this application specification. Figures 1A to 5 As shown, a small massage mechanism and a massage device with a small massage mechanism according to a first preferred embodiment of this application will be described in the following description, wherein the massage device includes, but is not limited to, office chairs, sofa chairs, lounge chairs, gaming chairs, etc.

[0051] The massage device includes a device body (not shown in the figure) and at least one small massage mechanism disposed on the device body, wherein the small massage mechanism is movably disposed on a movement track of the device body and can move along the movement track.

[0052] The small massage mechanism includes a base 10, a massage component 20 disposed on the base 10, and a walking component 30. The walking component 30 is disposed at the front end and / or rear end of the base 10 and is disposed on the moving track of the massage device body. It is used to drive the base 10 and the massage component 20 to move along the moving track of the massage device body to realize the displacement function of the mechanism.

[0053] The massage component 20 and the walking component 30 are fixed to the base 10, which provides support for them. The base 10 has a front side 101 and a back side 102 facing back to back, and at least one mounting channel 103 extending through the front side 101 and the back side 102. At least a portion of the structure of the massage component 20 and the walking component 30 extends from the front side 101 of the base 10 to the back side 102 through the mounting channel 103. That is, the massage component 20 and the walking component 30 are fixed to the front and back sides of the base 10, which helps to reduce the overall height. In other words, in this preferred embodiment of the present application, the massage component 20 and the walking component 30 of the small massage mechanism are not fixed to the front 101 or the back 102 of the base 10, but pass through the mounting channel 103 of the base 10 and are fixed to the front 101 and the back 102 of the base 10. This not only helps to improve the stability of the installation, but also makes the overall height dimension more compact, which is conducive to the overall miniaturization and thinning.

[0054] like Figure 2As 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 at both ends (front and rear ends) of the base 10, supporting the base 10 and the massage assembly 20. The walking motor 31 is connected to the first walking mechanism 33 via the walking transmission mechanism 32, driving the connected first walking mechanism 33 to move. It is understood that in this preferred embodiment of the application, the first walking mechanism 33 is implemented as an active walking mechanism, and the second walking mechanism 34 is a passive walking mechanism.

[0055] The walking motor 31 is fixed to the back of the base 10, and the first walking mechanism 33 and the second walking mechanism 34 of the walking assembly 30 are disposed on the front 101 of the base 10, 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 disposed on the same side of the base 10, and at least a portion of the structure of the massage assembly 20 is embedded in the mounting channel 103 of the base 10 to reduce the overall thickness of the small massage mechanism, which is beneficial for miniaturization of the mechanism.

[0056] The walking transmission mechanism 32 of the walking assembly 30 is implemented as a worm gear mechanism, wherein the walking transmission mechanism 32 passes through the mounting channel 103 of the base 10 and is tractably connected to the walking motor 31 and the first walking mechanism 33. 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 a drive walking wheel 333 located inside the first walking support wheel 332, wherein the first walking support wheel 332 and the drive 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 drive walking wheel 333 to rotate. It is worth mentioning that, in this preferred embodiment of the present application, the drive walking wheel 333 is implemented as a gear, which meshes with the track of the main unit of the device.

[0057] 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.

[0058] The walking motor 31 is fixed to the back of the base 10 and is connected to the first walking mechanism 33 through the walking transmission mechanism 32, driving its movement. The worm gear of the walking transmission mechanism 32 adopts a two-stage worm gear transmission, which can effectively adjust the torque and speed to ensure stable power transmission.

[0059] In this preferred embodiment of the present application, the walking motor 31, the walking transmission mechanism 32 and the first walking mechanism 33 form a U-shaped mechanism, that is, the walking motor 31 is parallel to the axis of the first walking shaft 331 of the first walking mechanism 33, and the walking transmission mechanism 32 is perpendicular to the axial direction of the walking motor 31 and the first walking shaft 331.

[0060] As an example, in a specific embodiment of this application, the axial direction of the walking motor 31 is parallel to the axial direction of the first walking shaft 331 of the first walking mechanism 33 (e.g., horizontally opposite), and the axial direction of the walking transmission mechanism 32 is perpendicular to the axial direction of the first walking shaft 331. In this preferred embodiment of this application, the walking motor 31 and the first walking shaft 331 of the first walking mechanism 33 are parallel or substantially parallel, so that the walking motor 31, the first walking shaft 331, and the walking transmission mechanism 32 form a U-shaped transmission connection structure, which can save space in the width or length direction and is beneficial to the overall miniaturization. It is worth mentioning that in the prior art, the connection between the walking motor and the walking mechanism is mostly a vertical connection, that is, the axial direction of the walking motor is perpendicular to the axial direction of the walking mechanism, which makes the lateral dimension between the walking motor and the walking mechanism larger.

[0061] The first walking mechanism 33, as the active walking mechanism, has a first walking support wheel 332 and an active walking wheel 333 mounted 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 drives, the power is transmitted to the first walking shaft 331 through the transmission mechanism, which in turn drives 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.

[0062] 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 and the massage component 20. 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.

In other words, in this preferred embodiment of the present application, the walking component 30 is neither fixed to the front surface 101 nor the back surface 102 of the base 10, but rather the front surface 101 of the base 10 extends through the mounting channel 103. This facilitates a reduction in the dimension in the height direction, and promotes miniaturization and thinning of the overall structure.

[0064] The walking transmission mechanism 32 is implemented as a double worm gear structure to achieve an extremely high reduction ratio and unparalleled self-locking reliability within a compact space, while maintaining smooth and quiet operation. Specifically, the walking transmission mechanism 32 includes a first worm gear 321 and a second worm gear 322, wherein the first worm gear 321 and the second worm gear 322 are connected, and the first worm gear 321 is connected to the walking motor 31, and the second worm gear 322 is connected to the first walking mechanism 33. The walking motor 31 drives the first walking mechanism 33 to move through the first worm gear 321 and the second worm gear 322.

[0065] The first worm gear 321 further includes a first worm wheel unit 3211 and a first worm unit 3212 meshing with each other, wherein the first worm unit 3212 is connected to the drive shaft of the travel motor 31 and is driven to rotate synchronously by the drive shaft of the travel motor 31; the second worm gear 322 further includes a second turbine unit 3221 and a second worm unit 3222 meshing with each other, wherein the second worm unit 3222 is connected to the first turbine unit 3211 and coaxially arranged, the second worm wheel unit 3221 is arranged on the first travel shaft 331 of the first travel mechanism 33, the first turbine unit 3211 drives the second worm unit 3222 to rotate synchronously, and then the second worm unit 3222 and the meshing second worm wheel unit 3221 drive the first travel shaft 331 of the first travel mechanism 33 to rotate.

[0069] In this preferred embodiment of the present application, the kneading mechanism 22 is fixed to the front side of the base 10, the pounding mechanism 23 is fixed to the back side 102 of the base 10, and the pounding mechanism 23 extends from the back side 102 of the base 10 through the mounting channel 103 to the front side 101 of the base 10.

[0070] Furthermore, in this preferred embodiment of the present application, the base 10 is further provided with at least one mounting groove 104, wherein the mounting groove 104 is formed on the back surface 102 of the base 10, and the percussion mechanism 23 of the massage assembly 20 is fixed within the mounting groove 104 of the base 10. It is understood that in this preferred embodiment of the present application, the mounting groove 104 is a recess formed on the back surface of the base 10, wherein the percussion mechanism 23 is fixed within the mounting groove 104, which can prevent the percussion mechanism 23 from protruding excessively, thereby affecting the installation of the entire unit in the massage device.

[0071] 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.

[0072] The kneading transmission mechanism 222 is implemented as a worm gear transmission 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.

[0073] Preferably, in this preferred embodiment of the application, the kneading transmission mechanism 222 is implemented as a two-stage transmission mechanism, that is, the kneading transmission mechanism 222 further includes a worm gear mechanism and a gear transmission mechanism, wherein the worm gear mechanism and the gear transmission mechanism are connected, the worm gear mechanism is tractably connected between the kneading motor 221 and the gear transmission mechanism, and the gear transmission mechanism is connected to the kneading eccentric shaft 223. The kneading motor 221 drives the kneading eccentric shaft 223 to rotate eccentrically through the worm gear mechanism and the gear transmission mechanism of the kneading transmission mechanism 222, thereby driving the massage arm 221 to perform kneading action.

[0074] In this application, the massage assembly 20 includes two massage arms 21, and a kneading mechanism 22 and a percussion mechanism 23 connected thereto. 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] 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.

[0076] 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 via 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 via 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, which is 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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 connecting bolt and an elastic connecting unit, wherein the connecting 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 connecting 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.

[0082] 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.

[0083] 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 connecting bolt and a tension spring (elastic connecting unit). The connecting 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.

[0084] In other words, in this preferred embodiment of the present application, the massage arm 21 is no longer a fixed structure. The massage push arm 212 of the massage arm 21 is movably connected to the curved arm 211. The connecting unit 214 provides a pre-tight elastic tension to the massage push arm 212. When the massage ball 213 of the massage arm 21 is subjected to a squeezing or pushing force, the massage push arm 212 of the massage arm 21 rotates along the connecting bolt to adjust the appropriate massage angle and intensity. When the force disappears, the massage push arm 212 of the massage arm 21 returns to its initial position under the elastic tension of the connecting unit 214.
