The first end of the limiting rod is fixedly connected to the second connecting part, and the second end of the limiting rod is provided with a sliding ball head. The swing limiting wheel is provided with a first connecting hole and a sliding groove that is circumferentially closed around the first connecting hole. The first connecting hole is connected to the first output shaft, and the sliding ball head is slidably installed in the sliding groove. When the sliding ball head slides along the sliding groove, the second connecting part swings along the second direction Y.

[0016] In some embodiments of this application, the sliding groove is a circular groove provided on one end face of the swing limiting wheel, and the center of the circular groove is eccentrically set relative to the axis of the first connecting hole.

[0017] In some embodiments of this application, the sliding groove is a wave-shaped groove disposed on one end face of the swing limiting wheel.

[0018] In some embodiments of this application, both the first mounting structure and the second mounting structure are configured as arc-shaped grooves. The massager also includes a mounting shaft that passes through the first mounting structure and the second mounting structure, and both ends of the mounting shaft are respectively connected to the housing.

[0023] This application has at least the following beneficial effects:

[0024] When a user uses the massager, activating the drive mechanism, power is simultaneously output through the first and second output shafts. The power from the first output shaft drives the first massage mechanism via the first output section and simultaneously drives the second massage mechanism via the second output section. The second output shaft drives the third massage mechanism. Thus, the first, second, and third massage mechanisms work together to simultaneously massage the user's neck, shoulders, and back. When the first massage mechanism performs a massage operation, the first output section drives the first connecting part to swing along the first direction X, using the first mounting structure as a fulcrum. Simultaneously, because the second connecting part of the first massage mechanism is hinged to the first connecting part and restricted by the swing limiting part, the second connecting part swings along the second direction Y while swinging along the first direction X with the first connecting part. This causes the second connecting part to drive the first massage head to perform a kneading massage on the user's neck and shoulders, relaxing the neck and shoulder muscles and relieving neck and shoulder fatigue. When the second massage mechanism performs a massage operation, the second output section drives the connecting end of the swing arm body to swing along the first direction X, using the second mounting structure as a fulcrum, which in turn drives the massage end to swing along the first direction X, using the second mounting structure as a fulcrum. In this way, the massage end applies a pressing massage to the user's back, relaxing the back muscles and relieving back fatigue. When the third massage mechanism performs its massage operation, the second output shaft drives the second massage head via the transmission unit. The second massage head then applies a hammering massage to the user's shoulders, further relaxing the shoulders and relieving shoulder fatigue. It is evident that this massager combines multiple massage methods, simultaneously massaging the user's neck, shoulders, and back. This diverse combination of massage functions relieves neck, shoulder, and back fatigue and soreness caused by prolonged sitting, allowing users to relax and effectively preventing neck, shoulder, and back strain, thus greatly benefiting the user's health.

[0049] Example 1:

[0050] like Figure 2 and Figure 3As shown, the massager provided in Embodiment 1 of this application includes a housing 10, a drive mechanism 20, and a massage assembly 30. The housing 10 includes a bottom shell 11 and a cover 12, with the cover 12 fitting over the bottom shell 11 to form an assembly space for assembling the drive mechanism 20. The drive mechanism 20 is mounted on the housing 10. Specifically, the outer shell of the drive mechanism 20 is provided with multiple mounting ears 23, which are locked to the bottom shell 11 by screws. A rubber pad 24 is provided between the screw and the mounting ear 23, allowing the drive mechanism 20 to adapt and adjust itself to the housing 10 when the screws are locked. Then, the cover 12 is closed. The drive mechanism 20 includes a first output shaft 21 and a second output shaft 22, both of which extend through the assembly space formed by the bottom shell 11 and the cover 12. The first output shaft 21 is connected to a first output section 211 and a second output section 212. The massage assembly 30 includes a first massage mechanism 31, a second massage mechanism 32, and a third massage mechanism 33. The first massage mechanism 31 includes a first connecting part 311, a second connecting part 312, a swing limiting part 313, and a first massage head 314. The first connecting part 311 and the first end of the second connecting part 312 are 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 drive connection structure 3112. The first mounting structure 3111 is movably connected to the housing 10, and the drive connection structure 3112 is connected to the first output part 211. The first output part 211 drives the first connecting part 311 to swing around the first mounting structure 3111 in a first direction X. The first end of the swing limiting part 313 is connected to the second connecting part 312, and the second end of the swing limiting part 313 is connected to the housing 10. When the first connecting part 311 swings, the swing limiting part 313 restricts the second connecting part 312, so that the second connecting part 312 swings relative to the first connecting part 311 in a second direction Y. The second massage mechanism 32 includes a swing arm body 321, which has a connecting end 3211, a massage end 3212, and a second mounting structure 3213. The second mounting structure 3213 is located between the connecting end 3211 and the massage end 3212 and is movably connected to the housing 10. The connecting end 3211 is connected to the second output part 212, which drives the massage end 3212 to swing around the second mounting structure 3213 in the first direction X. The third massage mechanism 33 includes a transmission part 331 and a second massage head 332. The transmission part 331 is mounted on the housing 10 and 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 tapping action. The plane parallel to the first direction X is perpendicular to the plane parallel to the second direction Y.

[0051] Wherein: "First direction X" is: described by the swing trajectory of the massage end 3212, which is an arc trajectory. The plane on which the arc trajectory is located is perpendicular to the axis of the first output shaft 21, and the plane on which the arc trajectory is located is also parallel to the length direction of the swing arm body 321; "Second direction Y" is: described by the swing trajectory of the first massage head 314, which is also an arc trajectory. The plane on which the arc trajectory is located is parallel to the axis of the first output shaft 21, and the plane on which the arc trajectory is located is also parallel to the arrangement direction of the first connecting part 311 and the second connecting part 312.

[0052] like Figure 1As shown, user 100 uses the massager for massage. Activating the drive mechanism 20, power is simultaneously output through the first output shaft 21 and the second output shaft 22. The power output from the first output shaft 21 drives the first massage mechanism 31 through the first output section 211 and simultaneously drives the second massage mechanism 32 through the second output section 212. The second output shaft 22 drives the third massage mechanism 33. Thus, the first massage mechanism 31, the second massage mechanism 32, and the third massage mechanism 33 work together to simultaneously massage the user 100's neck, shoulders, and back. Furthermore, the first massage mechanism 31, the second massage mechanism 32, the third massage mechanism 33, and the housing 10 are all covered by a face cover 60 made of skin-friendly fabric (such as velvet or leather) to fit the user 100's skin, making the user 100 feel comfortable when wearing the massager. When the first massage mechanism 31 performs a 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. Simultaneously, 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 limiting part 313, the second connecting part 312 swings along the second direction Y while swinging along the first direction X with 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 user 100's shoulder and neck area, relaxing the user 100's shoulder and neck muscles and relieving shoulder and neck fatigue. When the second massage mechanism 32 performs a massage operation, the second output part 212 drives the connecting end 3211 of the swing arm 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 movable connection node between the second mounting structure 3213 and the housing 10 as the fulcrum. In this way, the massage end 3212 applies a pressing massage to the back of user 100, relaxing the back muscles 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 through the transmission part 331. The second massage head 332 then applies a hammering massage to the shoulders of user 100, further relaxing the shoulders and relieving shoulder fatigue. It is evident that this massager combines multiple massage methods, simultaneously massaging the neck, shoulders, and back of user 100. This diverse combination of massage functions relieves neck, shoulder, and back fatigue and soreness caused by prolonged sitting, allowing user 100 to relax and effectively preventing neck, shoulder, and back strain, thus greatly benefiting user 100's health.

[0053] In Embodiment 1 of this application, as Figures 3 to 5As shown, the swing limiting part 313 includes a limiting rod 3131 and a hinge member 3135. The two ends of the limiting rod 3131 are respectively provided with a first ball head 3132 and a second ball head 3133. During assembly, the hinge member 3135 is detachably connected to the housing 10 by screws. The first ball head 3132 is structurally hinged to the hinge member 3135. The second connecting part 312 is provided with a hinge structure 3121. The second ball head 3133 is hinged to the hinge structure 3121. The limiting block 3122 is placed at the opening of the hinge structure 3121 for the second ball head 3133 to enter and exit. The limiting block 3122 is positioned on the second connecting part 312 by fasteners. The limiting shaft 3123 is connected to the second connecting part 312. At this time, the limiting shaft 3123 is located above the limiting block 3122 to restrict the limiting block 3122 from detaching from the second connecting part 312. Thus, the limiting block 3122 blocks the second ball head 3133 to prevent the second ball head 3133 from detaching from the hinge structure 3121. In other words, the first output part 211, the first connecting part 311, the limiting rod 3131, and the hinge member 3135 form a four-bar linkage with the housing 10 as the support point. When the first output part 211 drives the first connecting part 311 to swing around the first mounting structure 3111 in the first direction X, the first connecting part 311 then drives the second connecting part 312 to swing in the first direction X. Since the second connecting part 312 is restricted by the limiting rod 3131 of the swing limiting part 313, the second connecting part 312 swings in the second direction Y at its hinge position with the first connecting part 311. That is, the swing trajectory of the second connecting part 312 in the second direction Y is defined by the limiting rod 3131, so that the second connecting part 312 swings in the second direction Y at the same time as the first connecting part 311 swings in the first direction X. In this way, the second connecting part 312 drives the first massage head 314 to perform a kneading massage on the user 100's shoulder and neck area, relaxing the user 100's shoulder and neck muscles and relieving shoulder and neck fatigue.

[0054] In the massager of Embodiment 1 of this application, one end of the limiting rod 3131 is integrally formed with the second ball head 3133, and the other end of the limiting rod 3131 passes through the hinge structure 3121 and is screwed to the first ball head 3132. During assembly, the other end of the limiting rod 3131 first passes through the hinge structure 3121, so that the second ball head 3133 is located inside the hinge structure 3121. Then, the other end of the limiting rod 3131 passes through the hinge member 3135. Then, the other end of the limiting rod 3131 is screwed to the first ball head 3132. Next, the hinge member 3135 is detachably connected to the housing 10 by screws. In this way, the assembly efficiency of the limiting rod 3131 is greatly improved.

[0055] In the massager of Embodiment 1 of this application, such as Figures 3 to 5As shown, both the first mounting structure 3111 and the second mounting structure 3213 are configured as arc-shaped grooves. Figure 3 As shown, the massager also 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 connected to the housing 10. Specifically, the bottom housing 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 provided on the bracket, and the other end of the mounting shaft 40 is provided on the side wall 13. When the first output part 211 drives the first connecting part 311 to swing along the first direction X, the arc-shaped slide groove and the mounting shaft 40 slide back and forth relative to each other, so that the first connecting part 311 swings along the first direction X with the mounting shaft 40 as the fulcrum, and then drives the second connecting part 312 to swing along the first direction X with the first connecting part 311. At the same time, the second connecting part 312 also swings along the second direction Y under the restriction of the swing limiting part 313. Furthermore, the "movable connection node between the second mounting structure 3213 and the housing 10" mentioned above is the mounting shaft 40.

[0056] like Figure 3As shown, the first output section 211 has a second connecting hole 2111 and a first cylindrical shaft surface 2112, and the second output section 212 has 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, that is, the third connecting hole 2121 and the second connecting hole 2111 are coaxially arranged. After the first output section 211 and the second output section 212 are joined together, the two ends 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 installed on the first output shaft 21 and clamp and limit the first output section 211 and the second output section 212 to prevent the first output section 211 and the second output section 212 from shifting their positions along the axial direction of the first output shaft 21. The drive connection structure 3112 is rotatably connected to the first cylindrical shaft surface 2112, and the connection end 3211 is rotatably connected to the second cylindrical shaft surface 2122. The axis of the first cylindrical shaft surface 2112 is eccentrically positioned relative to the axis of the second connecting hole 2111, and the axis of the second cylindrical shaft surface 2122 is eccentrically positioned relative to the axis of the third connecting hole 2121. Thus, when the drive mechanism 20 is activated 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 undergo 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 along the first direction X, allowing the first massage head 314 to perform a kneading massage on the user 100's shoulders and neck, relieving shoulder and neck fatigue. Furthermore, the second output unit 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 performs a pressing massage on the back of the user 100 to relieve back fatigue.

[0057] In the massager of Embodiment 1 of this application, the first output part 211 and the second output part 212 are integrally molded components. Specifically, the first output part 211 and the second output part 212 are made of plastic and integrally injection molded using an injection molding process, which greatly improves the production efficiency of manufacturing the first output part 211 and the second output part 212. Alternatively, the first output part 211 and the second output part 212 can be independent separate components. After the first output part 211 and the second output part 212 are manufactured separately, they can be assembled onto the first output shaft 21 respectively.

[0058] In the massager of Embodiment 1 of this application, such as Figure 3 As shown, the transmission unit 331 includes a crankshaft 3311 and a connecting rod 3314. (As...) Figure 3 , Figure 6 and Figure 14As shown, the crankshaft 3311 has a first connecting shaft 3312 and a second connecting shaft 3313, the axis of the second connecting shaft 3313 being eccentrically positioned relative to the axis of the first connecting shaft 3312. Figure 3 As shown, the first connecting shaft 3312 is rotatably mounted on the housing 10 via the first bearing 337. The first connecting shaft 3312 is the power input end. The first connecting shaft 3312 is coaxially connected to the second output shaft 22. 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, and the adapter block 3316 is sleeved on the first connecting shaft 3312. The coupling 3315 is sleeved on the adapter block 3316, and the two are connected by a key to achieve synchronous rotation. 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 via the second bearing 338, and the second end of the connecting rod 3314 is connected to the second massage head 332. Thus, when the second output shaft 22 rotates, it drives the first connecting shaft 3312 to rotate, which in turn drives the second connecting shaft 3313 to rotate eccentrically around the axis of the first connecting shaft 3312. The second connecting shaft 3313 then drives the connecting rod 3314 to reciprocate, thereby enabling the second massage head 332 to perform a hammering massage on the user 100's shoulders, further relaxing the shoulders and relieving shoulder fatigue.

[0059] like Figure 3 and Figure 14 As shown, the second massage head 332 includes a guide cylinder 3321, a piston slider 3323, a pin 3324, and a striking head 3325. The first end of the guide cylinder 3321 is connected to the housing 10, and the second end of the guide cylinder 3321 has a guide groove 3322 extending along its axis. The piston slider 3323 is slidably disposed within the guide cylinder 3321. The second end of the connecting rod 3314 is rotatably connected to the piston slider 3323 via the pin 3324, and the end of the pin 3324 is slidably disposed in the guide groove 3322. The striking head 3325 is connected to the piston slider 3323. In other words, 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 stroke-type reciprocating motion within the guide cylinder 3321. Subsequently, the piston slider 3323 drives the tapping head 3325 to perform a hammer-like massage on the user 100's shoulders, further relaxing the shoulders and relieving shoulder fatigue.

[0060] In order to stably mount the transmission unit 331 and the second massage head 332 onto the housing 10, therefore, as Figure 3 and Figure 14As shown, the third massage mechanism 33 also includes a first mounting base 333, a second mounting base 334, and a flexible mounting member 336. During assembly, the first mounting base 333 is fixedly connected to the housing 10, and the first mounting base 333 has an assembly port 3331. The first connecting shaft 3312 is rotatably mounted between the housing 10 and the first mounting base 333. The second mounting base 334 is connected to the first mounting base 333 to form a receiving space 335, which communicates with the assembly port 3331. The flexible mounting member 336 is clamped and fixed 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 extends out of the second mounting base 334. The connecting rod 3314 connected to the second connecting shaft 3313 extends from the assembly port 3331 into the guide cylinder 3321 and connects to the piston slider 3323. Since the guide cylinder 3321 is installed between the first mounting base 333 and the second mounting base 334 through the flexible mounting member 336, the guide cylinder 3321 can adaptively adjust the assembly allowance generated by the elastic deformation of the flexible mounting member 336 relative to the first mounting base 333 and the second mounting base 334 to quickly adapt to the completion of assembly. This reduces the assembly accuracy requirements between components such as the first mounting base 333, the second mounting base 334, and the guide cylinder 3321, reduces assembly difficulty, and improves assembly efficiency.

[0061] like Figure 2 As shown, there are two of each of the first massage mechanism 31, the second massage mechanism 32, and the third massage mechanism 33. The two first massage mechanisms 31, the two second massage mechanisms 32, and the two third massage mechanisms 33 are symmetrically arranged relative to the drive mechanism 20. The first massage heads 314 of the two first massage mechanisms 31 perform massage movements that move closer or further apart from each other. Specifically, the two first massage heads 314 perform a kneading massage motion on the shoulder and neck area, mimicking hand kneading, to relax the shoulder and neck muscles of the user 100, relieve shoulder and neck fatigue, and make the massage more comfortable. Furthermore, the massage ends 3212 of the two second massage mechanisms 32 simultaneously massage the left and right sides of the user 100's back, relaxing the back muscles and relieving back fatigue. Further, the second massage heads of the two third massage mechanisms 33 simultaneously perform a tapping massage on the left and right shoulders of the user 100, further relaxing the shoulders and relieving shoulder fatigue.

[0062] Example 2:

[0063] Compared with the massager of Example 1, the massager of Example 2 has the following differences.

[0064] In Embodiment 2 of this application, as Figures 7 to 13As 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 (the first end of the limiting rod 3131 is the first end of the swing limiting part 313), and the second end of the limiting rod 3131 is provided with a sliding ball head 3134. Furthermore, the swing limiting wheel 3136 is provided with a first connecting hole 3137 and a sliding groove 3138 that is circumferentially closed around the first connecting hole 3137. The first connecting hole 3137 is connected to the end of the first output shaft 21. That is to say, in this embodiment, the swing limiting wheel 3136 is the second end of the swing limiting part 313. Therefore, the above-mentioned "the second end of the swing limiting part 313 is connected to the housing 10" means that the swing limiting wheel 3136 is indirectly connected to the housing 10 through 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.

[0065] In this embodiment, the swing limiting wheel 3136 not only restricts the swing trajectory of the second end of the limiting rod 3131 along the second direction Y, but also, since the first end of the limiting rod 3131 is fixedly connected to the second connecting part 312, the second end of the limiting rod 3131 drives the second connecting part 312 to swing along the second direction Y when it swings. That is, the swing limiting wheel 3136 also has the driving function of driving the second connecting part 312 to swing along the second direction Y.

[0066] like Figure 10 and Figure 11 As 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 set relative to the axis of the first connecting hole 3137. At this time, when the swing limiting wheel 3136 rotates one revolution, the first massage head 314 completes the sequential reciprocating motion. The reciprocating motion frequency of the first massage head 314 is low, and the massage mode of the first massage head 314 is a gentle and slow massage mode.

[0067] Or, such as Figure 12 and Figure 13 As shown, the sliding groove 3138 is a wave-shaped 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 peaks and troughs in the wave 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 mode of the first massage head 314 belongs to the fast massage mode.

[0068] Compared with the massager in Example 1, the massager in Example 2 is identical in all aspects except for the above-mentioned structural differences, and will not be described again here.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
