Among them, the power output by the first output shaft drives the first massage mechanism through the first output portion. In this way, the first massage mechanism performs a massage operation on the user's neck and shoulders. When the first massage mechanism performs the massage operation, the first output portion drives the first connecting portion to swing along the first direction X around the first mounting structure. At the same time, since the second connecting portion of the first massage mechanism is hinged to the first connecting portion and is restricted by the swing restricting portion, the second connecting portion swings along the second direction Y while swinging along the first direction X with the first connecting portion. In this way, the second connecting portion drives the first massage head to perform a kneading massage on the user's shoulder and neck area, relaxing the user's shoulder and neck muscles and relieving shoulder and neck fatigue.

[0022] In the massager of the present application, power is transmitted between the driving mechanism and the first massage head of the first massage mechanism through the first output shaft, the first output portion, the first connecting portion, and the second connecting portion. Moreover, the second connecting portion plays a restricting role through the swing restricting portion so that the second connecting portion swings relative to the first connecting portion along the second direction Y, so that the first massage head can swing along the first direction X and can also swing along the second direction Y. Then, the first massage head performs a kneading massage on the user's shoulder and neck area, relieving shoulder and neck fatigue. Compared with the structural design of transmitting power through a gear transmission mechanism in the existing massager, the massager of the present application realizes power transmission by designing the structure at the connection nodes of each component, simplifies the assembly structure of the power transmission structure, and saves the assembly space required by the gear transmission mechanism in the existing massager, greatly reducing the overall volume of the massager. The smaller volume of the massager makes the user feel more comfortable when wearing the massager. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0044] Such as Figures 2 to 5As shown in the figure, the massager provided by the embodiment of the present application includes a housing 10, a driving mechanism 20, and a massage component. The housing 10 includes a bottom shell 11 and a shell cover 12. The shell cover 12 is covered on the bottom shell 11 to form an assembly space for assembling the driving mechanism 20. The driving mechanism 20 is installed in the housing 10. Specifically, a plurality of mounting ears 23 are provided on the outer shell of the driving mechanism 20. The mounting ears 23 are locked on the bottom shell 11 by screws, and a rubber pad 24 is provided between the screws and the mounting ears 23. The elastic deformation of the rubber pad 24 enables the driving mechanism 20 to adaptively adjust with the housing 10 when the screws are locked, and then the shell cover 12 can be covered. The driving mechanism 20 includes a first output shaft 21. The first output shaft 21 passes through the assembly space formed by the bottom shell 11 and the shell cover 12, and the first output shaft 21 is connected with a first output part 211. The massage component includes a first massage mechanism 31 and a swing limiting part 313. The first massage mechanism 31 includes a first connecting part 311, a second connecting part 312, and a first massage head 314. The first end of the first connecting part 311 and the second connecting part 312 is hinged by a hinge shaft 315. The first massage head 314 is connected to the second end of the second connecting part 312. The first connecting part 311 is provided with a first mounting structure 3111 and a driving connection structure 3112. The first mounting structure 3111 is movably connected to the housing 10, and the driving connection structure 3112 is connected to the first output part 211. The first output part 211 drives the first connecting part 311 to swing along the first direction X around the first mounting structure 3111. As Figures 2 to 5 shown, the swing limiting part 313 includes a limiting rod 3131 and a swing limiting wheel 3136. The first end of the limiting rod 3131 is fixedly connected to the second connecting part 312, and a sliding ball head 3134 is provided at the second end of the limiting rod 3131. Moreover, the swing limiting wheel 3136 is provided with a first connection hole 3137 and a sliding groove 3138 that is circumferentially closed around the first connection hole 3137. The first connection hole 3137 is connected to the end of the first output shaft 21, and the swing limiting wheel 3136 rotates synchronously with the first output shaft 21. The sliding ball head 3134 is slidably installed in the sliding groove 3138. When the sliding ball head 3134 slides along the sliding groove 3138, the second connecting part 312 swings along the second direction Y. Among them, the plane parallel to the first direction X is perpendicular to the plane parallel to the second direction Y.

[0045] Wherein: "the first direction X" is described as follows with reference to the swinging trajectory of the massage end 3212. The swinging trajectory of the massage end 3212 is an arc trajectory. The plane where the arc trajectory is located is perpendicular to the axis direction of the first output shaft 21, and the plane where the arc trajectory is located is also parallel to the length direction of the swing rod body 321. "The second direction Y" is described as follows with reference to the swinging trajectory of the first massage head 314. The swinging trajectory of the first massage head 314 is also an arc trajectory. The plane where the arc trajectory is located is parallel to the axis direction of the first output shaft 21, and the plane where the arc trajectory is located is also parallel to the arrangement direction of the first connecting portion 311 and the second connecting portion 312.

[0046] As Figure 1 shown, the user 100 uses this massager for massage. The driving mechanism 20 is started to output power through the first output shaft 21. Among them, the power output by the first output shaft 21 drives the first massage mechanism 31 through the first output portion 211. The first massage mechanism 31 performs a massage operation on the neck and shoulders of the user 100. Moreover, both the first massage mechanism 31 and the housing 10 are covered by the face cover 60. The face cover 60 is made of a skin-friendly fabric (such as suede fabric, leather, etc.) and fits the skin of the user 100, making the user 100 feel comfortable when wearing the massager. When the first massage mechanism 31 performs the massage operation, the first output portion 211 drives the first connecting portion 311 to swing along the first direction X with the first mounting structure 3111 as the fulcrum. At the same time, since the second connecting portion 312 of the first massage mechanism 31 is hinged to the first connecting portion 311 and is restricted by the swing restricting portion 313, therefore, the second connecting portion 312 swings along the second direction Y while swinging along the first direction X following the first connecting portion 311. In this way, the second connecting portion 312 drives the first massage head 314 to perform a kneading massage on the shoulder and neck parts of the user 100, relaxing the shoulder and neck muscles of the user 100 and relieving shoulder and neck fatigue.

[0047] In the massager of the present application, power is transmitted between the drive mechanism 20 and the first massage head 314 of the first massage mechanism 31 through the first output shaft 21, the first output portion 211, the first connection portion 311, and the second connection portion 312. Moreover, the second connection portion 312 is restricted by the swing restricting portion 313 so that the second connection portion 312 swings relative to the first connection portion 311 along the second direction Y. As a result, the first massage head 314 can swing both along the first direction X and along the second direction Y. Then, the first massage head 314 performs a kneading massage on the shoulder and neck area of the user 100 to relieve shoulder and neck fatigue. Compared with the structural design of transmitting power through a gear transmission mechanism in existing massagers, the massager of the present application realizes power transmission by designing the structure at the connection nodes of each component, simplifies the assembly structure of the power transmission structure, and saves the assembly space required by the gear transmission mechanism in existing massagers, greatly reducing the overall volume of the massager. With the reduced volume of the massager, the user 100 will feel more comfortable wearing the massager.

[0048] In this embodiment, the swing restricting wheel 3136 not only restricts the swing trajectory of the second end of the restricting rod 3131 along the second direction Y. Since the first end of the restricting rod 3131 is fixedly connected to the second connection portion 312, when the second end of the restricting rod 3131 swings, it drives the second connection portion 312 to swing along the second direction Y. That is, the swing restricting wheel 3136 also has the driving function of driving the second connection portion 312 to swing along the second direction Y.

[0049] In the massager of the embodiment of the present application, as Figures 2 to 4 shown, the first mounting structure 3111 is provided as an arc-shaped chute. As Figure 2 shown, the massager further includes a mounting shaft 40. The mounting shaft 40 passes through the first mounting structure 3111 (i.e., the mounting shaft 40 passes through the arc-shaped chute), and both ends of the mounting shaft 40 are respectively connected to the housing 10. Specifically, the bottom case 11 is provided with a bracket opposite to the side wall 13 of the assembly space for mounting the drive mechanism 20. One end of the mounting shaft 40 is disposed on the bracket, and the other end of the mounting shaft 40 is disposed on the side wall 13. When the first output portion 211 drives the first connection portion 311 to swing along the first direction X, the arc-shaped chute and the mounting shaft 40 reciprocally slide relative to each other, so that the first connection portion 311 swings around the mounting shaft 40 along the first direction X, and then drives the second connection portion 312 to swing along the first direction X with the first connection portion 311. At the same time, the second connection portion 312 also swings along the second direction Y under the restricting action of the swing restricting portion 313.

[0050] As Figures 5 to 7As shown, the sliding groove 3138 is a circular groove provided on one end face of the swing limiting wheel 3136, and the center of the circular groove is eccentrically arranged with respect to the hole axis of the first connection hole 3137. At this time, when the swing limiting wheel 3136 rotates one circle, the first massage head 314 completes a reciprocating motion in sequence. The reciprocating motion frequency of the first massage head 314 is relatively low, and the massage method of the first massage head 314 belongs to a gentle slow massage method.

[0051] Or, as Figure 8 and Figure 9 shown, the sliding groove 3138 is a wavy groove provided on one end face of the swing limiting wheel 3136. At this time, during the rotation of the swing limiting wheel 3136, the adjacent wave crest and wave trough in the wavy shape correspond to one reciprocating motion of the first massage head 314. Therefore, the reciprocating motion frequency of the first massage head 314 is relatively high, and the massage method of the first massage head 314 belongs to a fast massage method.

[0052] As Figure 2 shown, the first output part 211 is provided with a second connection hole 2111 and a first cylindrical shaft surface 2112. The first output shaft 21 passes through the second connection hole 2111 and is connected to the first connection hole 3137. The driving connection structure 3112 is rotatably connected to the first cylindrical shaft surface 2112. Among them, the axis of the first cylindrical shaft surface 2112 is parallel to the hole axis of the second connection hole 2111, and there is a distance between the axis of the first cylindrical shaft surface 2112 and the axis of the second connection hole 2111 (that is, the axis of the first cylindrical shaft surface 2112 and the axis of the second connection hole 2111 are not arranged on the same straight line). In this way, when the driving mechanism 20 is started and the first output shaft 21 drives the first output part 211 to rotate, the first cylindrical shaft surface 2112 makes an eccentric motion around the axis of the first output shaft 21. Furthermore, the first output part 211 drives the first connection part 311 to swing around the first installation structure 3111 along the first direction X, and then the first massage head 314 kneads and massages the shoulder and neck parts of the user 100 to relieve shoulder and neck fatigue.

[0053] As Figures 2 to 5 shown, the first output shaft 21 is further connected to a second output part 212. The second massage mechanism 32 includes a swing rod body 321. The swing rod body 321 is provided with a connection end 3211, a massage end 3212 and a second installation structure 3213. The second installation structure 3213 is located between the connection end 3211 and the massage end 3212. The second installation structure 3213 is movably connected to the housing 10. The connection end 3211 is connected to the second output part 212, and the second output part 212 drives the massage end 3212 to swing around the second installation structure 3213 along the first direction X.

[0054] In the massager of the embodiment of the present application, as Figures 2 to 4As shown, the first mounting structure 3111 and the second mounting structure 3213 are both arranged as arc-shaped sliding grooves. As Figure 2 shown, the massager further includes a mounting shaft 40. The mounting shaft 40 passes through the first mounting structure 3111 and the second mounting structure 3213, and both ends of the mounting shaft 40 are respectively connected to the housing 10. Specifically, the bottom case 11 is provided with a bracket opposite to the side wall 13 of the assembly space for mounting the driving mechanism 20. One end of the mounting shaft 40 is arranged on the bracket, and the other end of the mounting shaft 40 is arranged on the side wall 13. When the first output part 211 drives the first connecting part 311 to swing in the first direction X, the arc-shaped sliding groove and the mounting shaft 40 reciprocate relative to each other. Moreover, the first connecting part 311 swinging in the first direction X drives the second connecting part 312 to swing in the first direction X along with the first connecting part 311. At the same time, the second connecting part 312 also swings in the second direction Y under the limiting action of the swing limiting part 313.

[0055] As Figure 2 shown, the second output part 212 is provided with a third connecting hole 2121 and a second cylindrical shaft surface 2122. The first output shaft 21 passes through the third connecting hole 2121 and the second connecting hole 2111 in sequence and then is connected to the first connecting hole 3137. That is, the axis of the third connecting hole 2121 and the axis of the second connecting hole 2111 are located on the same straight line. Moreover, both ends of the first output part 211 and the second output part 212 after being butted together are respectively provided with a first end cap 213 and a second end cap 214 for limiting. That is, the first end cap 213 and the second end cap 214 are mounted on the first output shaft 21 and clamp and limit the first output part 211 and the second output part 212 to prevent the first output part 211 and the second output part 212 from axially shifting positions along the first output shaft 21. The connecting end 3211 is rotatably connected to the second cylindrical shaft surface 2122. The axis of the second cylindrical shaft surface 2122 is eccentrically arranged relative to the axis of the third connecting hole 2121. In this way, when the driving mechanism 20 is started and the first output shaft 21 drives the first output part 211 and the second output part 212 to rotate, both the first cylindrical shaft surface 2112 and the second cylindrical shaft surface 2122 perform eccentric motion around the axis of the first output shaft 21. Furthermore, the first output part 211 drives the first connecting part 311 to swing around the first mounting structure 3111 in the first direction X, then the first massage head 314 kneads and massages the shoulder and neck parts of the user 100 to relieve shoulder and neck fatigue. And, the second output part 212 drives the connecting end 3211 to swing around the second mounting structure 3213 in the first direction X, that is, the massage end 3212 swings around the second mounting structure 3213 in the first direction X, and the massage end 3212 presses and massages the back of the user 100 to relieve back fatigue.

[0056] In the massager according to the embodiment of the present application, the first output portion 211 and the second output portion 212 are integrally formed components. Specifically, the first output portion 211 and the second output portion 212 are integrally injection molded using a plastic material through an injection molding process, which greatly improves the production efficiency of manufacturing the first output portion 211 and the second output portion 212. Alternatively, the first output portion 211 and the second output portion 212 may be independent individual components. After the first output portion 211 and the second output portion 212 are separately manufactured and formed, they can be respectively assembled onto the first output shaft 21.

[0057] As Figure 2 shown, the drive mechanism 20 further includes a second output shaft 22 arranged in parallel with the first output shaft 21. Moreover, the massage assembly further includes a third massage mechanism 33. The third massage mechanism 33 includes a transmission assembly 331 and a second massage head 332. The transmission assembly 331 is installed in the housing 10. The transmission assembly 331 has a power input end and a power output end. The power input end is connected to the second output shaft 22, and the power output end is connected to the second massage head 332 to drive the second massage head 332 to perform a knocking action. As Figure 1As shown, user 100 uses this massager for massage. The drive mechanism 20 is started, and power is output simultaneously through the first output shaft 21 and the second output shaft 22. Among them, the power output by the first output shaft 21 drives the first massage mechanism 31 through the first output part 211 and simultaneously drives the second massage mechanism 32 through the second output part 212. The second output shaft 22 drives the third massage mechanism 33. In this way, the first massage mechanism 31, the second massage mechanism 32, and the third massage mechanism 33 work together to perform massage operations on the neck, shoulders, and back of user 100 simultaneously. When the first massage mechanism 31 performs the massage operation, the first output part 211 drives the first connecting part 311 to swing along the first direction X with the first mounting structure 3111 as the fulcrum. At the same time, since the second connecting part 312 of the first massage mechanism 31 is hinged to the first connecting part 311 and is restricted by the swing restricting part 313, the second connecting part 312 swings along the second direction Y while swinging along the first direction X following the first connecting part 311. In this way, the second connecting part 312 drives the first massage head 314 to perform a kneading massage on the shoulder and neck area of user 100, relaxing the shoulder and neck muscles of user 100 and relieving shoulder and neck fatigue. When the second massage mechanism 32 performs the massage operation, the second output part 212 drives the connecting end 3211 of the swing rod body 321 to swing along the first direction X with the second mounting structure 3213 as the fulcrum, and then drives the massage end 3212 to swing along the first direction X with the second mounting structure 3213 as the fulcrum. In this way, the massage end 3212 performs a pressing massage on the back of user 100, relaxing the back muscles of user 100 and relieving back fatigue. When the third massage mechanism 33 performs the massage operation, the second output shaft 22 drives the second massage head 332 to move through the transmission assembly 331, and then the second massage head 332 performs a hammering massage on the shoulders of user 100, further relaxing the shoulders and relieving shoulder fatigue. It can be seen that this massager combines multiple massage methods, can massage the neck, shoulders, and back of user 100 simultaneously, combines various massage functions, relieves the neck, shoulder, and back fatigue and soreness caused by sitting at a desk for a long time, enables user 100 to relax, and effectively prevents and treats neck, shoulder, and back strain lesions, which is of great benefit to the health of user 100.

[0058] In the massager according to the embodiment of the present application, as Figure 2 and Figure 11 shown, the transmission assembly 331 includes a crankshaft 3311 and a connecting rod 3314. As Figure 2 、 Figure 10 and Figure 11 shown, the crankshaft 3311 has a first connecting shaft 3312 and a second connecting shaft 3313, and the axis of the second connecting shaft 3313 is eccentrically arranged relative to the axis of the first connecting shaft 3312. As Figure 2As shown in the figure, the first connecting shaft 3312 is rotatably mounted on the housing 10 through the first bearing 337. The first connecting shaft 3312 is the power input end. The first connecting shaft 3312 is connected to the second output shaft 22, and the axis of the first connecting shaft 3312 and the axis of the second output shaft 22 are on the same straight line. Specifically, a coupling 3315 and an adapter block 3316 are provided between the first connecting shaft 3312 and the second output shaft 22. The coupling 3315 is sleeved on the end of the second output shaft 22, the adapter block 3316 is sleeved on the first connecting shaft 3312, and the coupling 3315 is sleeved on the adapter block 3316, and the two are synchronously rotated through key connection. The connecting rod 3314 is the power output end. The second connecting shaft 3313 and the first end of the connecting rod 3314 are rotatably connected through the second bearing 338. The second end of the connecting rod 3314 is connected to the second massage head 332. In this way, when the second output shaft 22 rotates, the second output shaft 22 drives the first connecting shaft 3312 to rotate, and then drives the second connecting shaft 3313 to perform eccentric rotation around the axis of the first connecting shaft 3312. Then the second connecting shaft 3313 drives the connecting rod 3314 to reciprocate, so that the second massage head 332 performs a hammering massage on the shoulder of the user 100, further relaxing the shoulder and relieving shoulder fatigue.

[0059] As Figure 2 and Figure 11 shown in the figure, the second massage head 332 includes a guide cylinder 3321, a piston slider 3323, a pin shaft 3324 and a percussion head 3325. The first end of the guide cylinder 3321 is connected to the housing 10. The second end of the guide cylinder 3321 is provided with a guide chute 3322 extending along its axis. The piston slider 3323 is slidably arranged in the guide cylinder 3321. The second end of the connecting rod 3314 and the piston slider 3323 are rotatably connected through the pin shaft 3324, and the end of the pin shaft 3324 is slidably arranged in the guide chute 3322. The percussion head 3325 is connected to the piston slider 3323. That is to say, the connecting rod 3314 and the piston slider 3323 are similar to the piston connecting rod structure of an internal combustion engine, and the guide cylinder 3321 is similar to the cylinder of an internal combustion engine. Thus, the connecting rod 3314 drives the piston slider 3323 to perform a reciprocating motion in the guide cylinder 3321, and then the piston slider 3323 drives the percussion head 3325 to perform a hammering massage on the shoulder of the user 100, further relaxing the shoulder and relieving shoulder fatigue.

[0060] In order to stably mount the transmission assembly 331 and the second massage head 332 on the housing 10, therefore, as Figure 2 and Figure 11As shown, the third massage mechanism 33 further includes a first mounting seat 333, a second mounting seat 334, and a flexible mounting member 336. During assembly, the first mounting seat 333 is fixedly connected to the housing 10. The first mounting seat 333 is provided with an assembly port 3331. The first connecting shaft 3312 is rotatably mounted between the housing 10 and the first mounting seat 333. The second mounting seat 334 is connected to the first mounting seat 333. A receiving space 335 is formed between the first mounting seat 333 and the second mounting seat 334 (and the above-mentioned bracket for assembling one end of the mounting shaft 40 is formed by the cooperation of the first mounting seat 333 and the second mounting seat 334). The receiving space 335 communicates with the assembly port 3331. The flexible mounting member 336 is clamped and fixed by the first mounting seat 333 and the second mounting seat 334, and the flexible mounting member 336 is located in the receiving space 335. The first end of the guide cylinder 3321 is connected to the flexible mounting member 336, and the second end of the guide cylinder 3321 passes through the second mounting seat 334 and is connected to the connecting rod 3314 of the second connecting shaft 3313, which extends from the assembly port 3331 into the guide cylinder 3321 and is connected to the piston slider 3323. Since the guide cylinder 3321 is mounted between the first mounting seat 333 and the second mounting seat 334 through the flexible mounting member 336, the guide cylinder 3321 can be adaptively adjusted relative to the first mounting seat 333 and the second mounting seat 334 through the assembly allowance generated by the elastic deformation of the flexible mounting member 336 to quickly adapt to the completion of assembly, thereby reducing the assembly accuracy requirements between components such as the first mounting seat 333, the second mounting seat 334, and the guide cylinder 3321, reducing the assembly difficulty, and improving the assembly efficiency.

[0061] As Figure 2 shown, there are two first massage mechanisms 31, two second massage mechanisms 32, and two third massage mechanisms 33. Between the two first massage mechanisms 31, between the two second massage mechanisms 32, and between the two third massage mechanisms 33, they are symmetrically arranged relative to the drive mechanism 20. The first massage heads 314 of the two first massage mechanisms 31 perform massage actions of approaching or separating from each other. That is, a kneading massage action imitating hand kneading is performed on the shoulder and neck area between the two first massage heads 314, and a kneading massage is performed on the shoulder and neck area of the user 100 to relax the shoulder and neck muscles of the user 100 and relieve shoulder and neck fatigue, making the massage effect more comfortable. And, the massage ends 3212 of the two second massage mechanisms 32 massage the left and right sides of the back of the user 100 at the same time to relax the back muscles of the user 100 and relieve back fatigue. Further, the second massage heads of the two third massage mechanisms 33 perform hammering massages on the left shoulder and the right shoulder of the user 100 at the same time to further relax the shoulders and relieve shoulder fatigue.

[0062] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
