Technical Field

[0001] This application relates to the field of shoulder and neck massage equipment technology, and more specifically to an integrated massage mechanism and massage equipment. Background Technology

[0002] Neck and shoulder massagers are common massage devices used to massage and relax neck and shoulder muscles. They typically include neck and shoulder massage rods; the neck rod massages the neck muscles, and the shoulder rod massages the shoulder muscles. However, some neck and shoulder massagers lack features such as adjustable neck massage width and shoulder muscle tapping, failing to meet these needs. Summary of the Invention

[0004] To achieve the above objectives, this application provides an integrated massage mechanism, comprising a first shaft, a second shaft, a power source, a shoulder massage mechanism, a third shaft, a first clutch, and a second clutch. The first shaft passes through a width adjustment mechanism and a neck massage mechanism, respectively. The width adjustment mechanism is connected to the neck massage mechanism and drives the neck massage mechanism to translate along the first shaft. The power source is connected to the first shaft via a first reduction gear mechanism. The second shaft is parallel to the first shaft and is connected to the width adjustment mechanism. The second shaft passes through the first clutch, and the first clutch rotates synchronously with the second shaft. When the first clutch is coupled to the first reduction gear mechanism, the power source drives the second shaft to rotate via the first reduction gear mechanism and the first clutch. A first eccentric member is provided in the tapping rotating part of the shoulder massage mechanism. The end of the third shaft passes through the first eccentric member to drive the first eccentric member to rotate. The second clutch is located on the third shaft.

When the second clutch is coupled to the second reduction gear mechanism, the power source drives the third shaft to rotate via the second reduction gear mechanism and the second clutch.

[0005] The technical solution of this application integrates the width adjustment and shoulder tapping functions. It also controls the opening and closing of the width adjustment function through the first clutch and the opening and closing of the tapping function through the second clutch.

[0043] One or more embodiments of an integrated massage mechanism integrate neck massage width adjustment and shoulder tapping massage functions to meet diverse usage needs. The massage mechanism can be installed in a neck and shoulder massager.

[0044] like Figure 1 As shown, the massage mechanism has a housing 40, which includes an upper housing 401 and a lower housing 402 that are fixedly connected to each other. The upper housing 401 and the lower housing 402 are fixedly connected by means of snap-fit, screws, etc. The housing 40 serves as a mounting base for the internal components of the massage mechanism, and also provides a certain degree of protection for the internal components.

[0045] Combination Figure 1 and Figure 2 As shown, the massage mechanism includes a neck massage mechanism 100, a first shaft 10, a second shaft 20, a third shaft 50, a power source 24, a shoulder massage mechanism 300, a first clutch 22, and a second clutch 51. The first shaft 10 passes through both the width adjustment mechanism 23 and the neck massage mechanism 100. Two neck massage mechanisms 100 are symmetrically distributed on both sides of the first shaft 10, and two width adjustment mechanisms 23 are also symmetrically distributed on both sides of the first shaft 10. Therefore, when adjusting the neck massage width, the axial position of both neck massage mechanisms 100 can be adjusted simultaneously. In other embodiments, if only the width of one side of the neck massage mechanism is adjusted, no width adjustment mechanism is provided on the opposite side.

[0046] like Figure 2 As shown, the power source 24 is connected to the first shaft 10 via the first reduction transmission mechanism 60. The first shaft 10 drives the neck massage mechanism 100 to perform neck massage movements. The first reduction transmission mechanism 60 is divided into a first-stage reduction and a second-stage reduction. The first-stage reduction is achieved through a worm gear mechanism, and the second-stage reduction is achieved through a reduction gear pair. Through the two-stage reduction, the speed reduction of the first shaft 10 is reduced, and the torque is increased.

[0047] Combination Figure 1 and Figure 2 As shown, the width adjustment mechanism 23 is connected to the neck massage mechanism 100 and is used to drive the neck massage mechanism 100 to translate along the first axis 10 to adjust the neck massage width. The second axis 20 is parallel to the first axis 10 and is driven by the width adjustment mechanism 23. The second axis 20 passes through the first clutch 22 and rotates synchronously with the second axis 20. When the first clutch 22 is coupled with the first reduction transmission mechanism 60, the power source 24 drives the second axis 20 to rotate through the first reduction transmission mechanism 60 and the first clutch 22. The second axis 20 then drives the neck massage mechanism 100 to move axially through the width adjustment mechanism 23. Therefore, the start and stop switching of the width adjustment function can be controlled by controlling the coupling and decoupling of the first clutch 22 and the first reduction transmission mechanism 60.

[0048] like Figure 2As shown, the shoulder massage mechanism 300 has a first eccentric member 313 inside the tapping rotating part 311. The end of the third shaft 50 passes through the first eccentric member 313 to drive the first eccentric member 313 to rotate. A second clutch 51 is provided on the third shaft 50. The power source 24 is also connected to a second reduction transmission mechanism 70. When the second clutch 51 is coupled with the second reduction transmission mechanism 70, the power source 24 drives the third shaft 50 to rotate through the second reduction transmission mechanism 70 and the second clutch 51. The third shaft 50 then drives the first eccentric member 323 to rotate, thereby realizing the shoulder tapping massage function. In practice, the rotational speed of the third shaft 50 is higher than that of the first shaft 10, and the eccentricity of the first eccentric member 313 is smaller, thereby increasing the tapping speed and reducing the tapping amplitude.

[0049] Therefore, the massage mechanism of this embodiment integrates neck width adjustment function and shoulder tapping massage function. The power source 24 provides driving force for width adjustment and tapping. The first clutch 22 controls the opening and closing of the width adjustment function, and the second clutch 51 controls the opening and closing of the tapping function, so that users can use the width adjustment function and tapping function as needed, thereby improving the integration of the product and meeting diverse usage needs.

[0050] like Figure 2 As shown, the power source 24 is a motor, and its output shaft is perpendicular to the first shaft 10. The second reduction transmission mechanism 70 includes a cylindrical reduction gear pair 71 and a bevel gear pair 72. The output shaft of the power source 24 drives the pinion of the cylindrical reduction gear pair 71, and the large gear of the bevel gear pair 72 is passed through the third shaft 50. In at least one embodiment, the second clutch 51 is a one-way clutch or a one-way bearing. A part of the second clutch 51 is fixedly connected to the third shaft 50, and the other part rotates synchronously with the large gear of the bevel gear pair 72. When the power source 24 rotates in one direction, the second clutch 51 is always in a decoupled state, and the third shaft 50 is not driven to rotate. However, when the power source 24 rotates in the opposite direction, the second clutch 51 is in a coupled state, that is, the second clutch 51 is coupled with the second reduction transmission mechanism 70. The power source 24 drives the third shaft 50 to rotate through the second reduction transmission mechanism 70 and the second clutch 51 to realize the shoulder tapping massage function. The shoulder tapping massage function is started and stopped by the forward and reverse rotation of the second clutch 51 and the power source 24, which makes it convenient for users to use as needed and makes it easier to control the start and stop, which helps to better control costs.

[0051] In at least one embodiment, such as Figure 2As shown, the tapping rotating part 311 of the shoulder massage mechanism 300 is a round hole, and the first eccentric member 313 is a disc with an eccentric hole 3131. The first eccentric member 313 is located inside the tapping rotating part 311 and forms a rotatable connection. The third shaft 50 passes through the eccentric hole 3131 to drive the first eccentric member 313 to rotate around the third shaft 50. There is an eccentric distance between the third shaft 50 and the center of the tapping rotating part 311. When the first eccentric member 313 rotates, it drives the tapping rotating part 311 to swing slightly, and the outer end of the shoulder massage rod will follow with a slight swing.

[0052] In addition, such as Figure 3 As shown, a bearing 314 is provided between the first eccentric member 313 and the striking rotation part 311. The striking rotation part 311 is also fitted with a retaining clip 315. The retaining clip 315 is used to hold the bearing 314 and the first eccentric member 313 in the striking rotation part 311 to prevent the bearing 314 and the first eccentric member 313 from detaching and causing functional failure.

[0053] In at least one embodiment, such as Figure 2 and Figure 3 As shown, the shoulder massage mechanism 300 includes a shoulder massage rod 31, and a tapping rotating part 311 is disposed on the shoulder massage rod 31. There are two symmetrical shoulder massage mechanisms 300, therefore there are also two shoulder massage rods 31, symmetrically disposed on both outer sides of the third axis 50. The shoulder massage mechanism 300 is separated from the neck massage mechanism 100 on the first axis 10. The axial position adjustment of the neck massage mechanism 100 will not interfere with the shoulder massage mechanism 300, which helps to ensure the normal operation of the various functions of both the neck massage mechanism 100 and the shoulder massage mechanism 300.

[0054] In addition to providing shoulder tapping massage, the shoulder massage mechanism 300 also needs to provide regular shoulder pressing functions. Therefore, in at least one embodiment, such as... Figure 3 As shown, the shoulder massage mechanism 300 also includes a connecting rod 33, a second eccentric member 32, and a fourth shaft 30. The fourth shaft 30 is parallel to the first shaft 10 and passes through the second eccentric member 32. The second eccentric member 32 is connected to the shoulder massage rod 31 via the connecting rod 33. The central axis of the tapping rotating part 311 is the rotation axis 312 of the shoulder massage rod 31. Therefore, when the second eccentric member 32 rotates, it drives the shoulder massage rod 31 to oscillate back and forth around the rotation axis 312. In practice, the fourth shaft 30 is used to support the second eccentric member 32. The second eccentric member 32 rotates around the fourth shaft 30, but the fourth shaft 30 does not necessarily rotate synchronously with the second eccentric member 32.

[0055] In at least one embodiment, such as Figure 3As shown, the first shaft 10 is connected to the second eccentric member 32 via a constant speed gear set 301. That is, when the first shaft 10 rotates, it drives the neck massage mechanism 100 and simultaneously drives the shoulder massage rod 31 to reciprocate via the second eccentric member 32. In implementation, due to the use of the constant speed gear set 301, the rotational speed of the first shaft 10 is the same as that of the second eccentric member 32, which allows the neck massage frequency to be basically the same as the shoulder massage frequency. Figure 3 As shown, the two ends of the first shaft 10 are synchronously driven by the constant speed gear set 301 to drive the two second eccentric parts 32, so that the shoulder massage rods 31 on both sides can swing back and forth synchronously to ensure a better massage effect.

[0056] In at least one embodiment, such as Figure 2 As shown, the second eccentric member 32 includes a shaft sleeve portion 322, a gear portion 321, and an eccentric column 323. The fourth shaft 30 passes through the shaft sleeve portion 322 and the two are coaxial, and the shaft sleeve portion 322 and the fourth shaft 30 are rotatably connected. The gear portion 321 is the driven gear of the constant velocity gear set 301. The gear portion 321 is located at one end of the shaft sleeve portion 322, while the eccentric column 323 is located on the end face 3221 of the other end of the shaft sleeve portion 322.

[0057] like Figure 3 As shown, the axis of the eccentric column 323 is parallel to the axis of the shaft cylinder 322 and the distance between them is greater than zero. Therefore, when the second eccentric member 32 rotates, the eccentric column 323 rotates eccentrically around the fourth axis 30 with the distance between them as the radius. Moreover, the eccentric column 323 passes through one end of the connecting rod 33 and forms a rotatable connection, and the other end of the connecting rod 33 is hinged to the shoulder massage rod 31. Therefore, the second eccentric member 32, the connecting rod 33, and the shoulder massage rod 31 constitute a crank-rocker mechanism. For every revolution of the second eccentric member 32, the shoulder massage rod 31 swings back and forth once.

[0058] In practice, the gear part 321, the shaft sleeve part 322 and the eccentric column 323 are integrally formed, for example, by 3D printing or integral injection molding.

[0059] In at least one embodiment, such as Figure 2As shown, the first reduction transmission mechanism 60 includes a worm gear 62 and a worm 61 meshing with each other. The power source 24 drives the worm 61 to rotate, and the worm 61 drives the worm gear 62 to rotate to achieve the first stage of reduction. The meshing transmission method of the worm 61 and worm gear 62 has a large transmission ratio, can withstand a large amount of power, and has a compact structure, smooth transmission, low noise, and self-locking property, preventing the shoulder massage mechanism 300 and the neck massage mechanism 100 from being pushed in the opposite direction by external forces, which helps to improve the stability of the product. At the same time, the worm gear 62 is also connected to the first shaft 10 through a reduction gear pair 63. The pinion of the reduction gear pair 63 is integrated with the worm gear 62. After two stages of reduction, the first shaft 10 has a lower speed and a larger torque, enabling it to drive two neck massage mechanisms 100 and two shoulder massage mechanisms 300 simultaneously.

[0060] In at least one embodiment, such as Figure 4 As shown, the second shaft 20 passes through the worm gear 62 and the first clutch member 22. The worm gear 62 is located on one side of the first clutch member 22. The first clutch member 22 can be coupled or decoupled from the worm gear 62 by moving along the axial direction of the second shaft 20. The first clutch member 22 and the second shaft 20 rotate synchronously. Specifically, the first clutch member 22 and the second shaft 20 are fixedly connected. When the first clutch member 22 moves axially, the second shaft 20 moves axially synchronously with the first clutch member 22. When the first clutch member 22 rotates, the second shaft 20 rotates with the first clutch member 22.

[0061] like Figure 4 As shown, when the first clutch 22 is coupled to the worm gear 62, the worm gear 62 drives the second shaft 20 to rotate through the first clutch 22. Figure 3 As shown, when the first clutch 22 is decoupled from the worm gear 62, the first clutch 22 and the second shaft 20 stop rotating, and the worm gear 62 cannot drive the second shaft 20 to rotate. Therefore, the first clutch 22 can be coupled or decoupled from the worm gear 62 as needed to achieve the start and stop of the width adjustment function.

[0062] The first clutch element 22 and the worm gear 62 achieve coupled transmission through the engagement of teeth and grooves. For example... Figure 5 As shown, the first clutch 22 has at least one synchronizing tooth 222 extending axially, located on the side facing the worm gear 62. The worm gear 62 has a plurality of tooth grooves 621 evenly distributed circumferentially. When the synchronizing tooth 222 enters any tooth groove 621, the first clutch 22 and the worm gear 62 are coupled, causing them to rotate synchronously. Specifically, there are eight synchronizing teeth 222 evenly distributed circumferentially, and the tooth grooves 621 of the worm gear 62 correspond one-to-one with the synchronizing teeth 222. By coupling the worm gear 62 with the eight synchronizing teeth 222, the force on a single synchronizing tooth 222 is reduced, the worm gear 62 can transmit a larger torque, and the transmission between the worm gear 62 and the first clutch 22 is more reliable.

[0063] In addition, such as Figure 5 As shown, each synchronizing tooth 222 has two inclined surfaces 2221 at its outer end, and the partition between adjacent tooth grooves 621 is also provided with two inclined guide surfaces 6211. When the synchronizing tooth 222 gradually approaches the tooth groove 621, if the inclined surface 2221 of the synchronizing tooth 222 contacts the inclined guide surface 6211, the inclined guide surface 6211 will guide the synchronizing tooth 222 to pass into the tooth groove 621 on one side, so that the engagement between the synchronizing tooth 222 and the tooth groove 621 is smoother, and the situation of jamming and failure to form effective coupling is avoided.

[0064] The first clutch element 22 translates along the second axis 20, requiring a mechanism to drive the translation of the first clutch element 22. In at least one embodiment, such as Figure 5 As shown, the first clutch 22 is connected to a lever 25, and the lever 25 moves parallel to the axial direction of the second shaft 20. The lever 25 does not rotate with the first clutch 22. The lever 25 is used to drive the first clutch 22 to translate along the axial direction of the second shaft 20 to switch between the coupling state and the decoupling state of the first clutch 22 and the worm gear 62.

[0065] In at least one embodiment, the toggle 25 is driven by the clutch motor 26. Specifically, as shown... Figure 5 As shown, the shifter 25 has a rack 251, which is parallel to the second shaft 20. The rack 251 and the shifter 25 are integrated. The rack 251 meshes with the pinion 261 on the output shaft of the clutch motor 26. The clutch motor 26 drives the shifter 25 to translate axially along the second shaft 20 via the pinion 261 and the rack 251. When coupling is required, the output shaft of the clutch motor 26 rotates, driving the shifter 25 and the first clutch member 22 to translate until the synchronizing teeth 222 of the first clutch member 22 insert into the tooth groove 621, thus coupling the first clutch member 22 with the worm gear 62. When decoupling is required, the output shaft of the clutch motor 26 rotates in the opposite direction, and the synchronizing teeth 222 of the first clutch member 22 leave the tooth groove 621, thus decoupling the first clutch member 22 from the worm gear 62.

[0066] In implementation, when the clutch motor 26 drives the rack 251 and the lever 25 to move horizontally, it is necessary to promptly stop the clutch motor 26 to enhance its protection. For example, if the clutch motor 26's speed is detected to be zero but its power increases, it indicates that the rack 251 has reached its stop point. At this time, the input voltage to the clutch motor 26 needs to be cut off in time to prevent damage to the clutch motor 26. Alternatively, proximity switches can be installed at both ends of the rack 251's travel. These switches detect whether the rack 251 has reached the set stop position. When the proximity switches detect that the rack 251 has reached the stop point, the input voltage to the clutch motor 26 is promptly cut off to prevent damage to the clutch motor 26.

[0067] like Figure 5As shown, the first clutch 22 has a disc 221, and the second shaft 20 passes through the center of the disc 221. The disc 221 and the first clutch 22 are integrated. The semi-circular lever 25 has an arc-shaped groove 252, and the disc 221 is placed in the arc-shaped groove 252 with a clearance fit. When the first clutch 22 rotates, there is relative sliding between the disc 221 and the arc-shaped groove 252. Moreover, when the first clutch 22 rotates with the worm gear 62, the first clutch 22 has a tendency to disengage from the worm gear 62. The clutch motor 26 maintains the position of the first clutch 22 through the rack 251 and the lever 25, preventing the first clutch 22 from automatically disengaging from the worm gear 62 and ensuring the smooth progress of the adjustment process. The clutch motor 26 is selected with a self-locking function.

[0068] like Figure 5 As shown, the first clutch element 22 is fixedly connected to the second shaft 20. Specifically, a pin 201 passes through the second shaft 20, and the first clutch element 22 has a receiving hole 223, with both ends of the pin 201 placed in the receiving hole 223. The second shaft 20 also has a shaft retainer 202, which abuts against the other side of the first clutch element 22. Therefore, the first clutch element 22 and the second shaft 20 are fixedly connected by the pin 201 and the shaft retainer 202, allowing the first clutch element 22 and the second shaft 20 to rotate synchronously or translate axially synchronously. Figure 5 As shown, the drive gear 204 on the second shaft 20, which is used to connect the width adjustment mechanism, rotates synchronously with the second shaft 20. A pin 203 is provided on the second shaft 20 to engage with the axial elongated hole 2041 on the inner wall of the drive gear 204. When the second shaft 20 and the first clutch 22 move axially, the drive gear 204 maintains its axial position, thus maintaining its coupling with the width adjustment mechanism.

[0069] like Figure 4 As shown, the first shaft 10 passes through the width adjustment mechanism 23, which is connected to both the second shaft 20 and the neck massage mechanism 100. The width adjustment mechanism 23 is driven by the second shaft 20. When the second shaft 20 rotates, it adjusts the axial position of the neck massage mechanism 100 via the width adjustment mechanism 23. In practice, the second shaft 20 is connected to the width adjustment mechanism 23 via a reduction gear set, and the width adjustment mechanism 23 changes the axial position of the neck massage mechanism 100 via a screw drive mechanism. Figure 4 As shown, the neck massage mechanism 100 has two symmetrical parts. The two ends of the second shaft 20 drive the two width adjustment mechanisms 23 through the active gear 204 of the reduction gear set.

[0070] The width adjustment mechanism 23 adjusts the position of the neck massage mechanism 100 via a screw drive mechanism. In at least one embodiment, such as Figure 6As shown, the width adjustment mechanism 23 includes a driving cylinder 231 and a driven cylinder 232. The driving cylinder 231 is connected to the second shaft 20 via a reduction gear set. Specifically, the driving cylinder 231 has a driven gear 2311, and the second shaft 20 has a driving gear 204. The driving gear 204 and the driven gear 2311 mesh to form a reduction gear set. The radius of the driven gear 2311 is larger than the radius of the driving gear 204, so as to reduce the rotational speed of the driving cylinder 231 and increase the torque.

[0071] like Figure 6 As shown, the active cylinder 231 is inserted into the driven cylinder 232, and the two are threaded together. The driven cylinder 232 is connected to the neck massage mechanism 100. When the active cylinder 231 is driven to rotate by the second shaft 20, the driven cylinder 232 drives the neck massage mechanism 100 to move along the axial direction of the first shaft 10. The first shaft 10 and the active cylinder 231 are not connected by transmission, so the active cylinder 231 will not drive the first shaft 10 to rotate. That is, the active cylinder 231 and the first shaft 10 can rotate independently.

[0072] In practice, the external thread 2312 of the driving cylinder 231 and the internal thread 2323 of the driven cylinder 232 are both trapezoidal threads. The trapezoidal thread is used for helical transmission and can use its self-locking performance to keep the relative position of the driven cylinder 232 and the driving cylinder 231 unchanged, that is, to keep the axial position of the neck massage mechanism 100 unchanged.

[0073] In at least one embodiment, such as Figure 6 As shown, the driven cylinder 232 is also provided with an annular groove 2326. One end of the neck massage mechanism 100 is provided with an annular end plate 106, which is placed in the groove 2326. The end plate 106 and the groove 2326 are slidably connected. When the end plate 106 rotates, it will not drive the groove 2326 and the driven cylinder 232 to rotate, so that the neck massage mechanism 100 and the driven cylinder 232 are axially connected. At the same time, the neck massage mechanism 100 cannot drive the driven cylinder 232 to rotate. When the driven cylinder 232 translates axially, it will drive the neck massage mechanism 100 to translate axially, thereby changing the axial position of the neck massage mechanism 100.

[0074] In at least one embodiment, such as Figure 6 As shown, the driven cylinder 232 includes two symmetrical semi-cylinders 2322 and an enclosing cylinder 2321. An internal thread 2323 is provided on the inner arm of the semi-cylinder 2322. The slots 2326 of the two semi-cylinders 2322 are fitted onto the end plate 106, the two semi-cylinders 2322 are enclosed, and then the two semi-cylinders 2322 are inserted into the enclosing cylinder 2321 and fixed by the enclosing cylinder 2321, thus realizing the connection and installation of the driven cylinder 232 and the neck massage mechanism 100.

[0075] In addition, such as Figure 2As shown, a limiting post 2329 is provided below the surrounding cylinder 2321, and the limiting post 2329 passes through the corresponding straight groove 404 in the outer shell. Figure 1 In the first axis 10, the straight groove 404 extends axially and restricts the degree of freedom of the surrounding cylinder 2321 to rotate around the first axis 10.

[0076] In implementation, the surrounding cylinder 2321 and the two semi-cylinders 2322 are interference-fitted to reduce the need for additional fixed connection structures. In addition, the inner wall of the surrounding cylinder 2321 is provided with two axial protrusions 2324, and each semi-cylinder 2322 is provided with an axial groove 2325. The axial protrusions 2324 are correspondingly placed in the axial grooves 2325 to facilitate the positioning between the surrounding cylinder 2321 and the two semi-cylinders 2322, and also to prevent relative rotation between the semi-cylinders 2322 and the surrounding cylinder 2321.

[0077] In at least one embodiment, combined Figure 7 and Figure 8 As shown, the neck massage mechanism 100 includes a neck massage rod 12, an eccentric cylinder 11, and a clamping ring 13. A first shaft 10 passes through the eccentric cylinder 11 and drives the eccentric cylinder 11 to rotate. Specifically, as... Figure 8 As shown, at least one section of the first shaft 10 is a flat shaft 101, and the central hole of the eccentric cylinder 11 is a flat hole 1101. The shape and size of the flat shaft 101 are the same as those of the flat hole 1101. When the flat shaft 101 of the first shaft 10 passes through the flat hole 1101 of the eccentric cylinder 11, the first shaft 10 can drive the eccentric cylinder 11 to rotate around the first shaft 10.

[0078] Combination Figure 7 and Figure 8 As shown, the eccentric cylinder 11 is provided with a coaxial pressure plate 111, a first annular groove 112, and a shoulder 113. The first annular groove 112 is located between the pressure plate 111 and the shoulder 113. The outer diameter D3 of the shoulder 113 is larger than the outer diameter D1 of the first annular groove 112, and the outer diameter of the pressure plate 111 is larger than the outer diameter D1 of the first annular groove 112. Therefore, the pressure plate 111 and the shoulder 113 play an axial positioning role.

[0079] Combination Figure 7 and Figure 8 As shown, the neck massage rod 12 has a ring 121, which is fitted into the first annular groove 112. However, the first annular groove 112 does not cause the ring 121 or the neck massage rod 12 to rotate. The clamping ring 13 is used to fix the neck massage rod 12 to the eccentric cylinder 11. The clamping ring 13 is fitted between the pressure plate 111 and the shoulder 113, and the clamping ring 13 and the shoulder 113 abut against each other, so that the ring 121 of the neck massage rod 12 is clamped between the pressure plate 111 and the clamping ring 13.

[0080] like Figure 8As shown, the axial direction 110 of the first annular groove 112 forms an acute angle with the first shaft 10, for example, 5°, that is, the axial direction 110 of the first annular groove 112 forms the same acute angle with the central axis of the eccentric cylinder 11. The pressure plate 111, the first annular groove 112, and the shoulder 113 are coaxial, therefore the axial directions of the pressure plate 111 and the shoulder 113 are collinear with the axial direction 110 of the first annular groove 112. When the first shaft 10 drives the eccentric cylinder 11 to rotate, the pressure plate 111, the clamping ring 13, and the shoulder 113 will perform eccentric movement around the first shaft 10, and the neck massage rod 12 will penetrate the strip groove 403 of the outer shell. Figure 1 Since it is restricted from rotating with the first axis 10, the pressure plate 111 and the clamping ring 13 drive the neck massage rod 12 to make a small back-and-forth swinging motion.

[0081] In at least one embodiment, combined with Figure 7 and Figure 8 As shown, the eccentric cylinder 11 also has a second annular groove 114, which is located between the first annular groove 112 and the shoulder 113, and the second annular groove 114 is coaxial with the first annular groove 112. A clamping ring 13 is fitted into the second annular groove 114. The inner diameter of the clamping ring 13 is equal to the outer diameter D2 of the second annular groove 114, while the outer diameter D2 of the second annular groove 114 is smaller than the outer diameter D3 of the shoulder 113 and larger than the outer diameter D1 of the first annular groove 112. The second annular groove 114 is used to support and position the clamping ring 13. In practice, the pressure plate 111, the first annular groove 112, the second annular groove 114, and the shoulder 113 are integrally formed with the eccentric cylinder 11.

[0082] To facilitate the installation of the clamping ring 13 on the eccentric cylinder 11, in at least one embodiment, combined with Figure 8 and Figure 9 As shown, the clamping ring 13 is formed by two arc rings 131 in the circumferential direction, and the adjacent arc rings 131 of the clamping ring 13 are fixedly connected to each other. By dividing the clamping ring 13 into multiple arc rings 131, the installation difficulty caused by the inner diameter of the clamping ring 13 being smaller than the outer diameter of the shoulder 113 is avoided, and the ease of installation and disassembly of the clamping ring 13 on the eccentric cylinder 11 is improved.

[0083] In addition, combined Figure 7 and Figure 8 As shown, a clamping ring 14 is fitted onto the outer wall of the clamping ring 13. The clamping ring 14 is interference-fitted with each of the arcs 131 of the clamping ring 13, thus the clamping ring 14 is used to fix all the arcs 131 of the clamping ring 13. By fixing the arcs 131 of the clamping ring 13 with the clamping ring 14 through interference fit, the fixing structure is simplified and the reliability is improved. In implementation, the clamping ring 14 can be made of a metal material with better tensile strength, such as carbon steel.

[0084] To facilitate accurate positioning and installation of the clamping ring 13 and the shoulder 113, in at least one embodiment, such as Figure 9As shown, each arc ring 131 of the clamping ring 13 is provided with a positioning protrusion 132, and the outer wall of the shoulder 113 is provided with positioning grooves 1131 corresponding to the positioning protrusions 132. When the arc ring 131 is installed on the eccentric cylinder 11, the positioning protrusions 132 are inserted into the positioning grooves 1131 to form a snap-fit, thereby achieving accurate positioning of each arc ring 131. In practice, the positioning protrusions 132 of the arc ring 131 are axially extending strip-shaped protrusions.

[0085] In at least one embodiment, combined with Figure 7 and Figure 8 As shown, friction pads 123 are provided between the ring 121 and the pressure plate 111, and between the ring 121 and the clamping ring 13. The friction pads 123 reduce wear and friction, which helps to improve service life and also helps to reduce the rotational resistance of the first shaft 10. In practice, the friction pads 123 can be pads with a low coefficient of friction, such as PTFE pads.

[0086] The ring 121 of the neck massage rod 12 is a complete circle. When the ring 121 is installed in the eccentric cylinder 11, the inner diameter of the ring 121 is not less than the outer diameter of the shoulder 113, so that the ring 121 can fit into the eccentric cylinder 11. However, since the outer diameter of the first annular groove 112 is smaller than the outer diameter of the shoulder 113, a gap is left between the ring 121 and the first annular groove 112. Therefore, in at least one embodiment, such as Figure 7 As shown, the ring 121 includes a washer 122, which is fixed inside the ring 121 and fitted onto the first annular groove 112. Because the ring 121 is fitted onto the first annular groove 112 by the washer 122, there is no gap between the ring 121 and the first annular groove 112, preventing significant loosening of the neck massage rod 12. The washer 122 also serves to withstand friction and wear, reducing wear on the ring 121 of the neck massage rod 12. In practice, the washer 122 can be made of PTFE material.

[0087] To facilitate installation of the washer 122, the washer 122 adopts a split structure. In at least one embodiment, such as Figure 8 As shown, washer 122 is formed by two arc-shaped washers 1221 enclosing each other in the circumferential direction. Figure 9 As shown, the two arc-shaped washers 1221 of the washer 122 are fixed inside the ring 121. The ring 121 plays a role in fixing the arc-shaped washers 1221 and preventing the arc-shaped washers 1221 from coming loose.

[0088] To fix the washer 122 relative to the annulus 121, in at least one embodiment, such as Figure 8As shown, the boss 1222 is provided on the outer wall of the washer 122, and the corresponding groove 124 is provided on the inner wall of the ring 121. After the boss 1222 is inserted into the groove 124, the washer 122 cannot rotate relative to the ring 121, and the washer 122 and the ring 121 are fixed relative to each other. Figure 8 The middle washer 122 is divided into two arc-shaped washers 1221. Therefore, each arc-shaped washer 1221 is provided with a boss 1222. The two bosses 1222 are symmetrical to each other, and the corresponding grooves 124 are also symmetrical to each other.

[0089] When the massage mechanism is working, the power source 24 rotates in the forward direction. The power source 24 drives the first shaft 10 through the first reduction transmission mechanism 60. The first shaft 10 drives the neck massage mechanism 100 to perform neck massage movements. Simultaneously, the first shaft 10 drives the second eccentric member 32 to rotate through the constant speed gear set 301. The second eccentric member 32 drives the shoulder massage rod 31 to perform shoulder massage movements. When it is necessary to adjust the axial position of the neck massage mechanism 100, the clutch motor 26 drives the shifting member 25 to translate. The shifting member 25 pushes the first clutch member 22 to couple with the worm gear 62. The worm gear 62 drives the second shaft 20 to rotate. The second shaft 20 adjusts the axial position of the neck massage mechanism 100 through the width adjustment mechanism 23. When the power source 24 rotates in the forward direction, the second reduction transmission mechanism 70 remains rotating under the drive of the power source 24, and the second clutch member 51 is in a decoupled state. When shoulder tapping is needed, the power source 24 rotates in the opposite direction, and the second reduction transmission mechanism 70 rotates in the opposite direction under the drive of the power source 24. The second clutch 51 becomes coupled, and the power source 24 drives the third shaft 50 to rotate. The third shaft 50 then drives the shoulder massage rod 31 to perform shoulder tapping.
