[0022] Current massage devices generally suffer from limited massage modes and techniques, resulting in less than ideal massage effects and user experience. To address this, this application proposes a massage mechanism 10, comprising: Casing 100; Two massage components 300 are provided, and the two massage components 300 are symmetrically arranged on the housing 100. Each massage component 300 includes a plurality of massage heads 310 arranged side by side. The massage heads 310 on each massage component 300 are movably arranged relative to the housing 100 so as to have the farthest end close to the other massage component 300. The drive assembly 200 is mounted on the housing 100 and is connected in transmission to each massage assembly 300. The drive component 200 drives the massage heads 310 on the same massage component 300 to move asynchronously, so that each massage head 310 reaches its farthest point at a different time.

[0023] In the technical solution of this utility model, two massage components 300 are symmetrically arranged, and at least two massage heads 310 are arranged side by side on each massage component 300. The massage heads 310 on the two massage components 300 move symmetrically, and each massage head 310 in the massage component 300 has its farthest end closest to the other massage component 300 during movement. Driven by the drive component 200, the massage heads 310 on the same massage component 300 move asynchronously, so that the time for each massage head 310 on the same massage component 300 to reach its farthest end is different. In this way, the same massage component 300 can alternately massage different areas of the massage area 20. In addition, because the massage heads 310 on the two massage components 300 move symmetrically and cooperate with each other, different areas of the massage area 20 can also be alternately kneaded, enriching the massage techniques and improving the massage experience.

[0024] Specifically, such as Figures 1 to 8 The aforementioned massage mechanism 10 can be used in massagers for the neck, arms, or legs. The overall structure of the massage mechanism 10 consists of a housing 100, a drive assembly 200, and two massage components 300 symmetrically arranged on the housing 100. The housing 100 is the basic support structure of the massage mechanism 10. The housing 100 is a shell structure made of metal or plastic, and its interior has cavities for installing other components. The drive assembly 200 is fixed to the housing 100 and can be a transmission structure formed by a motor and multiple gears, providing power to the massage components 300. Figure 1 In this design, the drive assembly 200 is located in the middle of the housing 100, and two massage assemblies 300 are provided. The two massage assemblies 300 are symmetrically arranged on both sides of the drive assembly 200 and are respectively connected to the drive assembly 200 for transmission. Each massage assembly 300 includes multiple massage heads 310 arranged side by side, and the multiple massage heads 310 can move along... Figure 2The massage heads 310 can be arranged in a straight line or along a curve around the massage area 20. The multiple massage heads 310 on the two massage components 300 can also be arranged symmetrically. The drive component 200 is connected to each massage head 310, driving the massage head 310 to swing or slide on the housing 100. When the massage head 310 moves, it can move closer to or further away from the other massage component 300. After wearing the massage mechanism 10, each massage head 310 can move closer to or further away from the massage area 20. The position closest to the massage area 20 (which is also the position closest to the other massage component 300) is the farthest. At this position, the massage head 310 presses the massage area 20 with the greatest depth and force. After this position, the massage head 310 moves away from the massage area 20, thus relaxing the massage area 20. This reciprocating motion achieves the kneading and massaging of the massage area 20. Furthermore, within the same massage component 300, the drive component 200 can drive the massage heads 310 to move asynchronously according to a specific timing sequence. That is, the time it takes for each massage head 310 on the same massage component 300 to reach its farthest point is different. In this way, the time for each massage head 310 to knead different areas of the massage site 20 is also staggered, which can realize the alternating kneading of different areas of the massage site 20. In practical applications, the asynchronous movement of the massage heads 310 can be achieved by setting multiple independent drive units to drive each massage head 310, for example, by using multiple small motors to drive each massage head 310 to move. In addition, since the massage heads 310 of the two massage components 300 are spatially corresponding to each other, the movements of the massage heads 310 on the two massage components 300 are also symmetrical. The massage heads 310 on the two massage components 300 can form a pinching effect by working together. With the asynchronous movement of multiple massage heads 310, the alternating pinching of different areas of the massage site 20 can be achieved. Thus, the multiple massage heads 310 on a single massage component 300 alternately knead, and the alternating pinching and kneading of different parts by two massage components 300 can simulate the rhythm changes and flexible techniques of human hand massage, thereby enhancing the richness and realism of the massage movements and improving the user experience.

[0025] like Figure 4 and Figure 5 One implementation of the structure of the massage component 300 is shown. In this embodiment, the massage component 300 includes: The drive shaft 320 is rotatably mounted on the housing 100 and is connected to the drive assembly 200. The drive shafts 320 of the two massage assemblies 300 are arranged at an angle. Multiple eccentric wheels 330 are spaced apart along the axial direction of the drive shaft 320. The center lines of the multiple eccentric wheels 330 are all offset from the axis of the drive shaft 320 and are staggered from each other in the circumferential direction of the drive shaft 320. Each eccentric wheel 330 is connected to a massage head 310 in a transmission connection.

[0026] The drive shaft 320 is connected to the drive assembly 200 to transmit power from the drive assembly 200 to the massage head 310. The drive shaft 320 can be a solid or hollow shaft made of metal or plastic. The transmission between the drive shaft 320 and the massage assembly 300 can be a gear drive, a belt drive, or any other transmission method that adapts to the internal space of the housing 100. In addition, the massage mechanism 10 in this solution can be adapted for neck massage, and the two drive shafts 320 can be V-shaped with an included angle, with the two drive shafts 320 extending to both sides of the neck. Additionally, an eccentric wheel 330 is mounted on the drive shaft 320. The eccentric wheel 330 has a disc-like structure, and its center line is offset from the axis of the drive shaft 320. The center line of the eccentric wheel 330 can be parallel to the drive shaft 320 or at a certain angle to it. Multiple eccentric wheels 330 are provided, and they can be spaced apart along the axial direction of the drive shaft 320. The specific spacing depends on the required size of the area covering the massage area 20. Furthermore, the number of eccentric wheels 330 can be the same as that of the massage head 310. Each massage head 310 is connected to an eccentric wheel 330 in a driving manner. The connection between the massage head 310 and the eccentric wheel 330 can be varied. For example, the head and tail of the massage head 310 can be hinged, and the tail can be hinged to the eccentric wheel 330. The head of the massage head 310 can be slidably connected to the housing 100 and can slide towards or away from the massage area 20. In this way, the massage head 310 and the eccentric wheel 330 cooperate to form a crank-connecting rod mechanism. When the eccentric wheel 330 rotates, it drives the massage head 310 to reciprocate and press the massage area 20. Furthermore, to achieve asynchronous movement of the massage heads 310, the multiple eccentric wheels 330 can have a phase difference in the circumferential direction of the drive shaft 320, causing each massage head 310 to move asynchronously in time. When the drive shaft 320 rotates, the multiple eccentric wheels 330 can drive the massage heads 310 to press the massage area 20 at different times, achieving asynchronous movement. The drive shaft 320 and eccentric wheels 330 on the two massage components 300 are... Figure 2 The massage area 20 is symmetrical in the left-right direction, so that the massage heads 310 on both sides can create a pinching and kneading effect on the massage area 20. Through the above solution, multiple massage heads 310 can transmit power through a single drive shaft 320, which simplifies the structure of the transmission part while satisfying the above massage effect, and is conducive to the miniaturization of the massage mechanism 10.

[0027] In addition, such as Figure 5In another embodiment of this application, a bearing 350 may be provided on the drive shaft 320. The bearing 350 may be provided between every two adjacent massage heads 310. The drive shaft 320 may be rotatably connected to the housing 100 through the bearing 350. The auxiliary support of the bearing 350 can improve the dispersion of the force between the drive shaft 320 and the housing 100, and at the same time make the drive shaft 320 and its rotation more stable, and the massage action of the massage head 310 smoother.

[0028] like Figure 4 and Figure 6 In another embodiment of this application, the massage head 310 has a first connecting part 311 and a second connecting part 312, wherein the first connecting part 311 is rotatably connected to the eccentric wheel 330, and the rotation axis of the first connecting part 311 is parallel to and deviates from the rotation axis of the transmission shaft 320, and the second connecting part 312 is slidably engaged with the housing 100.

[0029] The first connecting part 311 can be disposed in the middle of the massage head 310. The first connecting part 311 can be rotatably connected to the eccentric wheel 330 through a structure such as a rotating shaft. The rotation axis of the first connecting part 311 and the eccentric wheel 330 can be parallel to the center line of the eccentric wheel 330. In addition, the second connecting part 312 is disposed at one end of the massage head 310. The second connecting part 312 can slide with the housing 100. The sliding direction can be perpendicular to the center line of the eccentric wheel 330. In this way, when the eccentric wheel 330 rotates, the massage head 310 can swing in a plane perpendicular to the center line of the eccentric wheel 330 by the mutual cooperation and limitation of the first connecting part 311 and the second connecting part 312. Figure 4 The part of the massage head 310 that contacts the massage area 20 will rotate around the drive shaft 320 on one hand, and on the other hand, the lower edge of the second connecting part 312 will be limited. Figure 4 The massage head 310 moves up and down, and when massaging the neck, the massage action is to press and rub along the length of the neck at the same time, which can simulate the massage effect of a real human hand and enhance the user's comfort experience.

[0030] In addition, such as Figure 6 In another embodiment of this application, the first connecting portion 311 is configured as a hole structure extending along the axial direction of the eccentric wheel 330, and the hole structure is rotatably engaged with the rim of the eccentric wheel 330. The first connecting part 311 is located in the middle of the massage head 310. It can adopt a hole structure extending axially along the eccentric wheel 330. This hole structure can be a cylindrical hole, into which the eccentric wheel 330 can pass. The rim of the eccentric wheel 330 can slide against the inner wall of the hole structure. When the eccentric wheel 330 rotates, it can drive the massage head 310 to move synchronously. Thus, since the rim of the eccentric wheel 330 has the largest range of motion, the above structure can increase the stroke of the massage head 310, improve the massage effect, and the massage head 310 and the eccentric wheel 330 can overlap axially in the transmission shaft 320, thereby reducing the size of the massage assembly 300 in the direction of the transmission shaft 320. In addition, as Figure 6 In another embodiment, the eccentric wheel 330 includes two parts: a wheel body 331 and a wheel cover 332. The wheel body 331 is provided with a part that rotates with the hole structure. The edges of the wheel body 331 and the wheel cover 332 can be provided with stepped structures. The two can be assembled from both sides of the massage head 310 along the axial direction of the transmission shaft 320 to clamp and limit the massage head 310. This can prevent the eccentric wheel 330 and the massage head 310 from moving relative to each other in the axial direction of the transmission shaft 320, improve the stability of the transmission, and ensure that the massage head 310 maintains smooth and stable operation.

[0031] like Figure 4 In another embodiment of this application, the slide groove 110 is disposed perpendicular to the drive shaft 320 and extends toward the farthest end, and the second connecting portion 312 slides in engagement with the slide groove 110. In this solution, in order to simplify the structure, the slide groove 110 structure can be integrally integrated on the housing 100. The slide groove 110 can be disposed on the side of the drive shaft 320 away from the other massage component 300, and the extension direction of the slide groove 110 is perpendicular to the drive shaft 320. In addition, the slide groove 110 also extends toward the farthest end when the massage head 310 moves. Furthermore, the second connecting portion 312 is a protrusion on the end of the massage head 310 away from the end that contacts the massage part 20, and the protrusion can slide in engagement with the slide groove 110. With the above structure, under the premise of the same sliding length of the second connecting part 312, the stroke of the massage head 310 can be maximized in the direction towards the massage component 300 on the other side, and the farthest end of the massage head 310 is also closer to the other massage component 300. This ensures that the symmetrical massage heads 310 on the two massage components 300 are also closest to each other to the maximum extent, so that the symmetrical massage heads 310 on the two massage components 300 can press the massage area 20 more deeply, which helps to improve the kneading force.

[0032] In another embodiment of this application, on each drive shaft 320, multiple eccentric wheels 330 are staggered in the same direction and arranged in a spiral pattern in the circumferential direction of the drive shaft 320; in this scheme, all adjacent eccentric wheels 330 are offset in the same direction in the circumferential direction of the drive shaft 320, so that the multiple eccentric wheels 330 are arranged in a spiral pattern on the drive shaft 320. With this design, during massage, multiple massage heads 310 will sequentially massage the massage area 20 along the axial direction of the drive shaft 320, such as... Figure 1 Taking the neck as an example for the massage area 20, the drive assembly 200 can be arranged at the back of the neck. The massage heads 310 of each massage assembly 300 can be arranged sequentially from the back of the neck to the front of the neck. During massage, multiple massage heads 310 will alternately knead different positions of the neck along the direction from the back of the neck to the front of the neck, or from the front of the neck to the back of the neck. This not only expands the massage area but also makes the massage experience more comfortable. In addition, the circumferential offset angle between any two adjacent eccentric wheels 330 can remain constant. In this solution, the circumferential offset angle of adjacent eccentric wheels 330 on the drive shaft 320 is preferably 30 degrees. This makes the kneading time interval between the massage heads 310 uniform, forming a stable massage rhythm, which helps to further improve the massage effect.

[0033] like Figure 4 , Figure 7 and Figure 8 The diagram illustrates a connection method between the drive shaft 320 and the eccentric wheel 330. In this embodiment, a connecting pin 340 protrudes from the outer peripheral wall of the drive shaft 320, and the eccentric wheel 330 is provided with a shaft hole and a pin hole 321 that pass through along the axial direction. The shaft hole and the pin hole 321 are connected, the drive shaft 320 passes through the shaft hole, and the connecting pin 340 passes through the pin hole 321. The connecting pin 340 is a protruding structure on the outer peripheral wall of the drive shaft 320. It can be integrally formed on the drive shaft 320, or the connecting pin 340 can be inserted into the pin hole 321 provided on the outer wall of the drive shaft 320. In addition, each eccentric wheel 330 is provided with a shaft hole off its own center line, and a pin hole 321 communicating with the shaft hole is provided in the radial direction of the shaft hole. The drive shaft 320 can be inserted into the shaft hole, and the connecting pin 340 can be inserted into the pin hole 321. When the drive shaft 320 rotates, the drive pin can abut against the inner wall of the pin hole 321 and drive the eccentric wheel 330 to rotate with the drive shaft 320. With the above structure, unless the transmission pin falls off the transmission shaft 320, the eccentric wheel 330 will always rotate synchronously with the transmission shaft 320, which improves the reliability of the connection between the eccentric wheel 330 and the transmission shaft 320. In addition, the transmission shaft 320 can be disassembled and assembled with the eccentric wheel 330 along its own axis, which also facilitates the assembly of the massage component 300.

[0034] like Figure 2In another embodiment of this application, the included angle between the two drive shafts 320 is 70 to 90 degrees. Verification has shown that this angle design prevents excessive pressure on the user's neck caused by an excessively small included angle, while simultaneously allowing the multiple massage heads 310 on the massage assembly 300 to cover a larger area of ​​the neck, ensuring the effectiveness of the massage.

[0035] like Figure 4 In another embodiment of this application, each massage head 310 is provided with a plurality of massage protrusions 313, which are spaced apart in the circumferential direction of the eccentric wheel 330. Specifically, the massage protrusions 313 can be any shape such as hemispherical or conical. To improve comfort, the massage protrusions 313 can be made of flexible materials such as silicone or rubber. Since the massage head 310 will swing circumferentially along the eccentric wheel 330, after providing a plurality of massage protrusions 313 along the axial direction of the eccentric wheel 330, the plurality of massage protrusions 313 can press the massage area 20 in turn. That is, a single massage head 310 can press more than 20 massage areas 20 in one cycle, and adjacent massage protrusions 313 can clamp the area between two massage protrusions 313 when pressing the massage area 20, achieving a similar pinching and kneading effect, which can further enrich the massage techniques and enhance the massage experience.

[0036] like Figure 3 As shown, in another embodiment of this application, the driving component 200 includes: The driver 210 is located in the middle of the housing 100 and has an output shaft; Worm gear 220, connected to the output shaft; Worm gear 230 is rotatably mounted on housing 100 and is connected to worm 220 for transmission. Gear assembly 240 is disposed on housing 100, and massage assembly 300 and worm gear 230 are connected by gear assembly 240.

[0037] Specifically, the driver 210 is a device that provides rotational power, which can be implemented by an electric motor. The driver 210 is located in the middle of the housing 100 to facilitate transmission to the massage components 300 on both sides. In addition, a worm gear 220 is provided on the output shaft of the driver 210, and a worm wheel 230 that cooperates with the worm gear 220 is provided on the housing 100. The cooperation between the worm wheel 230 and the worm gear 220 increases the output torque to meet the torque requirements of the kneading action. In addition, the worm wheel 230 and the massage component 300 are connected by a gear assembly 240. In this solution, the gear assembly 240 includes a first-stage spur gear reduction transmission and a first-stage bevel gear transmission. The purpose of setting the first-stage spur gear reduction transmission is to further improve the torque output, and the purpose of setting the first-stage bevel gear transmission is to realize the reversing transmission to adapt to the rotation direction of the transmission shaft 320. In addition, the aforementioned worm gear 230 and gear assembly 240 can be symmetrically arranged about the worm 220 so that the operation of the two massage components 300 can be driven simultaneously by a single driver 210. This simplifies the structure and ensures the synchronicity of the movements of the two massage components 300, thus guaranteeing the effect of pinching and kneading massage.

[0038] This utility model also proposes a massager for massaging the neck. The massager may include the massage mechanism 10 described above. The specific structure of the massage mechanism 10 is as described in the above embodiments. Since this massager adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. In addition, it is conceivable that, thanks to the symmetrical kneading structure of the massage mechanism 10, this massager can also be applied to massage other parts of the body. For example, when the massager is placed on the legs or arms, the massage heads 310 on both sides can also perform kneading massage on the legs or arms. This is also within the application scope of this massager.

[0039] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
