Description

Massage component and massage mechanism

[0001] This application claims priority to Chinese patent application No. 202322642286.0, filed on September 27, 2023, and all disclosed contents of that application are incorporated herein by reference. Technical Field

[0002] The present application relates to the technical field of massagers, and in particular to a massage component and a massage mechanism used in a massager. Background Art

[0003] Massagers, such as neck massagers, are often equipped with two sets of massage heads, which can swing independently to perform pinching and kneading massage.

[0004] In the prior art, the two groups of massage heads include a first massage head and a second massage head. The first massage head is connected to the transmission shaft via a first eccentric wheel, and the second massage head is connected to the transmission shaft via a second eccentric wheel. In order to prevent the first and second eccentric wheels from rotating relative to each other and to prevent interference between the first and second massage heads, the first and second eccentric wheels need to be connected via a clamping structure. Both ends of the first and second eccentric wheels need to be axially fixed to the eccentric shaft. This complex assembly structure requires high assembly precision, which is not conducive to improving assembly efficiency.

[0005] In addition, the first eccentric wheel and the second eccentric wheel are connected by a snap-fit ​​structure. If the snap-fit ​​structure is not properly assembled or becomes disengaged during use, it may easily cause the first eccentric wheel and the second eccentric wheel to move relative to each other, causing interference between the first massage head and the second massage head, thus affecting the user experience.

[0047] The following further describes the specific embodiments of the present application with reference to the accompanying drawings. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0048] As shown in Figures 1-10, an embodiment of the present application provides a massage assembly, including a transmission shaft 1, a first massage element 2, a second massage element 3 and a yaw drive 4 for driving the first massage element 2 and the second massage element 3 to perform yaw motion.

[0049] The first massage element 2 includes a first connecting arm 21 and a first massage head 22 connected to the first connecting arm 21 . The second massage element 3 includes a second connecting arm 31 and a second massage head 32 connected to the second connecting arm 31 .

[0050] The yaw driving member 4 is sleeved on the transmission shaft 1 , and includes a first driving portion 41 and a second driving portion 42 disposed inside the first driving portion 41 .

[0051] The circumferential surface 411 of the first driving portion 41 and the circumferential surface 421 of the second driving portion 42 are arranged to be inclined relative to the axis of the transmission shaft 1 .

[0052] The first connecting arm 21 is assembled on the first driving portion 41 , and the first driving portion 41 is rotatable relative to the first connecting arm 21 .

[0053] The second connecting arm 31 is assembled on the second driving portion 42 , and the second driving portion 42 is rotatable relative to the second connecting arm 31 .

[0054] The massage assembly provided in this application is a component of a massager, which includes a transmission shaft 1, a first massage element 2, a second massage element 3 and a yaw drive 4. The yaw drive 4 is sleeved on the transmission shaft 1 and is used to drive the first massage element 2 and the second massage element 3 to perform yaw motion.

[0055] The first massage element 2 includes a first connecting arm 21 and at least one first massage head 22. The first massage head 22 is connected to one end of the first connecting arm 21, and the other end of the first connecting arm 21 has a first mounting ring 211. The second massage element 3 includes a second connecting arm 31 and at least one second massage head 32. The second massage head 32 is connected to one end of the second connecting arm 31, and the other end of the second connecting arm 31 has a second mounting ring 311.

[0056] The yaw drive member 4 is cylindrical or cylindrical and is sleeved on the end of the transmission shaft 1. The yaw drive member 4 includes a cylindrical or cylindrical first drive portion 41 and a second drive portion 42. The second drive portion 42 is disposed inside the first drive portion 41.

[0057] The axis of the transmission shaft 1 and the axis of the first drive portion 41 are not parallel but arranged at an angle. Therefore, the circumferential surface 411 of the first drive portion 41 is arranged at an angle relative to the axis of the transmission shaft 1. The first mounting ring 211 of the first connecting arm 21 is assembled on the circumferential surface 411 of the first drive portion 41. The first mounting ring 211 is axially fixed to the first drive portion 41 and has a clearance fit on the first drive portion 41, allowing the first drive portion 41 to rotate relative to the first mounting ring 211.

[0058] Because the circumferential surface 411 is tilted relative to the axis of the transmission shaft 1, the circumferential surface of the first mounting ring 211 is also tilted relative to the axis of the transmission shaft 1, thereby causing the first connecting arm 21 to be tilted relative to the axis of the transmission shaft 1, and the first connecting arm 21 to be configured at an angle with the radial direction of the transmission shaft 1. When the transmission shaft 1 drives the yaw drive member 4, the first driving portion 41 rotates relative to the first connecting arm 21. The action of the circumferential surface 411 causes the first connecting arm 21 to swing left and right, thereby driving the first massage head 22 to swing left and right, thereby achieving a pinching and kneading massage or a rubbing massage.

[0059] Similarly, the axis of the transmission shaft 1 and the axis of the second drive portion 42 are not parallel but arranged at an angle. Consequently, the circumferential surface 421 of the second drive portion 42 is arranged at an angle relative to the axis of the transmission shaft 1. The second mounting ring 311 of the second connecting arm 31 is assembled onto the circumferential surface 421 of the second drive portion 42. The second mounting ring 311 is axially fixed to the second drive portion 42 and has a clearance fit thereon, allowing the second drive portion 42 to rotate relative to the second mounting ring 311.

[0060] Because the circumferential surface 421 is tilted relative to the axis of the transmission shaft 1, the circumferential surface of the second mounting ring 311 is also tilted relative to the axis of the transmission shaft 1, resulting in the second connecting arm 31 being tilted relative to the axis of the transmission shaft 1, and the second connecting arm 31 is configured at an angle to the radial direction of the transmission shaft 1. When the transmission shaft 1 drives the yaw drive member 4, the second driving portion 42 rotates relative to the second connecting arm 31. The action of the circumferential surface 421 causes the second connecting arm 31 to swing left and right, thereby driving the second massage head 32 to swing left and right, thereby achieving a pinching and kneading massage or a rubbing massage.

[0061] As required, the inclination modes of the circumferential surface 411 and the circumferential surface 421 can be set to be different or the same, so that the swing modes of the first massage element 2 and the second massage element 3 are the same or different.

[0062] In the massage assembly provided in the present application, the first massage element 2 and the second massage element 3 are assembled on a yaw drive component 4. The installation can be completed by sleeve-fitting the yaw drive component 4 onto the transmission shaft 1, which simplifies the installation structure, reduces the number of assembly parts, reduces the assembly difficulty, and is conducive to improving assembly efficiency.

[0063] Preferably, the second driving portion 42 is integrally provided inside the first driving portion 41 .

[0064] The first driving part 41 and the second driving part 42 of the deflection driving member 4 are arranged in an integrated manner, with high structural strength, stable connection, and will not break, effectively avoiding the interference between the first massage element 2 and the second massage element 3 caused by the relative rotation of the first driving part 41 and the second driving part 42, which is beneficial to improving the user experience.

[0065] In one embodiment, as shown in FIG. 4 and FIG. 8 , the circumferential surface 411 of the first driving portion 41 and the circumferential surface 421 of the second driving portion 42 have the same inclination angle relative to the axis of the transmission shaft 1 .

[0066] In this embodiment, the second driving portion 42 is coaxially arranged with the first driving portion 41 , and the circumferential surface 411 and the circumferential surface 421 are tilted in the same manner, thereby ensuring that the first massage element 2 and the second massage element 3 swing synchronously.

[0067] In one embodiment, as shown in Figures 3-4 and 6-9, the radius of the first driving portion 41 is greater than the radius of the second driving portion 42, so that the first driving portion 41 and the second driving portion 42 are distinguished, thereby avoiding incorrect installation positions of the first massage element 2 and the second massage element 3.

[0068] In one embodiment, as shown in Figure 2-8, the end of the first driving part 41 facing the second driving part 42 is provided with a stop ring 412 for stopping the first connecting arm 21, and the end of the first driving part 41 facing away from the second driving part 42 is connected to the end cover 5 for stopping the first connecting arm 21.

[0069] In this embodiment, a retaining ring 412 is integrally provided at the end where the first driving portion 41 and the second driving portion 42 meet. The free end of the first driving portion 41 is removably fitted with an end cap 5 to jointly limit the axial position of the first connecting arm 21. Specifically, a first mounting ring 211 is assembled between the end cap 5 and the retaining ring 412. The first mounting ring 211 is axially fixed on the circumferential surface 411 of the first driving portion 41 but is rotatable.

[0070] In one embodiment, as shown in FIG. 4 and FIG. 6 - 9 , a transition frustum 44 is provided between the first driving portion 41 and the second driving portion 42 .

[0071] One end of the transition truncated cone 44 is connected to the first driving portion 41 , and a step surface 441 is formed between the other end of the transition truncated cone 44 and the second driving portion 42 .

[0072] A limit ring 7 is provided on one end of the second driving portion 42 away from the step surface 441 , and the second connecting arm 31 is sandwiched between the step surface 441 and the limit ring 7 .

[0073] In this embodiment, a transition cone 44 is disposed between the first driving portion 41 and the second driving portion 42 to separate the first massage element 2 from the second massage element 3 and to axially position one end of the second connecting arm 31 .

[0074] The radius of the transition cone 44 gradually decreases along the direction from the first drive portion 41 to the second drive portion 42. The large end surface of the transition cone 44 connects to the first drive portion 41, while the small end surface of the transition cone 44 connects to the second drive portion 42. A step surface 441 is formed between the small end surface of the transition cone 44 and the second drive portion 42, which is used to stop the second connecting arm 31 and provide a position limit for one side of the second connecting arm 31. Specifically, the step surface 441 can contact the surface of the second mounting ring 311. If the second mounting ring 311 is mounted to the second drive portion 42 via the bearing 6, the step surface 441 will contact the inner ring of the bearing 6 to achieve axial positioning.

[0075] The second driving portion 42 is provided with a retaining ring 7 for limiting the position of the second connecting arm 31. The retaining ring 7 is arranged opposite the stepped surface 441 to limit the other side of the second connecting arm 31. The second connecting arm 31 is sandwiched between the stepped surface 441 and the retaining ring 7, thus limiting the axial position of the second connecting arm 31.

[0076] Specifically, the inner ring surface of the limiting retaining ring 7 is assembled into the retaining groove 422 of the second driving part 42 , and the main body of the limiting retaining ring 7 blocks the second connecting arm 31 .

[0077] In one embodiment, as shown in FIG. 1 , FIG. 4 and FIG. 7 - 10 , the yaw drive member 4 is connected to the transmission shaft 1 via a snap ring 8 , so that the yaw drive member 4 and the transmission shaft 1 are assembled together.

[0078] The snap ring 8 may be provided at the end of the first driving portion 41 and / or the second driving portion 42 .

[0079] In one embodiment, the end face of the second driving part 42 has a limiting end face 423 perpendicular to the transmission shaft 1, and a first limiting groove 12 is provided on the transmission shaft 1 at a position corresponding to the limiting end face 423. The retaining ring 8 is clamped in the first limiting groove 12 and is close to the limiting end face 423 to limit the movement of the yaw drive member 4 toward the middle of the transmission shaft 1.

[0080] A second limiting groove 13 is provided at the end of the transmission shaft 1. Another retaining ring 8 can be fitted into the second limiting groove 13 to engage with the first driving portion 41 or the stop surface of the end cover 5 to prevent the yaw drive member 4 from being separated from the transmission shaft 1. Of course, other methods can also be used to prevent the yaw drive member 4 from being separated from the transmission shaft 1.

[0081] In one embodiment, as shown in Figures 3, 6-7 and 9-10, the yaw drive member 4 is provided with a special-shaped through hole 43, and the end of the transmission shaft 1 has a plug-in end 11 adapted to the special-shaped through hole 43, and the plug-in end 11 is plugged into the special-shaped through hole 43.

[0082] In this embodiment, in order to facilitate the transmission shaft 1 to drive the yaw drive member 4 to rotate, a special-shaped through hole 43 is provided in the yaw drive member 4, which is a non-circular or elliptical through hole. Correspondingly, a plug-in end 11 with a non-circular or elliptical cross-section is provided at the end of the transmission shaft 1, and the plug-in end 11 is integrally formed with the transmission shaft 1.

[0083] During assembly, the plug end 11 is plugged into the special-shaped through hole 43 . When the plug end 11 rotates along with the transmission shaft 1 , the special-shaped assembly structure can transmit torque to drive the yaw drive member 4 to rotate.

[0084] The special-shaped through hole 43 can be a triangular hole, a rectangular hole, an arched hole, etc. Correspondingly, the cross section of the plug end 11 is also triangular, rectangular, arched, etc.

[0085] In one embodiment, as shown in Figures 3-4, the second connecting arm 31 is mounted on the second driving portion 42 via a bearing 6, so that the second driving portion 42 can rotate relative to the second connecting arm 31, thereby reducing friction between the two. Specifically, the bearing 6 is assembled in the second mounting ring 311.

[0086] In one embodiment, as shown in FIG. 1-3 , the second connecting arm 31 has a curved portion 312 to change the direction and position of the second massage head 32 . The direction of the force applied by the second massage head 32 can also be adjusted by adjusting the shape of the curved portion 312 .

[0087] In one embodiment, as shown in FIG. 1-3 , the second connecting arm 31 and the first connecting arm 21 are arranged crosswise, and the two are not on the same straight line or in the same plane, which can effectively avoid interference between the first massage element 2 and the second massage element 3 .

[0088] In one embodiment, as shown in FIG. 1-3 and FIG. 5 , the first massage head 22 is pivotally connected to the first connecting arm 21 , and / or the second massage head 32 is pivotally connected to the second connecting arm 31 .

[0089] In this embodiment, the first massage head 22 and the second massage head 32 can be configured as a rolling massage head or a fixed massage head as needed to meet different massage needs.

[0090] In one embodiment, the second massage head 32 is fixedly mounted on the end of the second connecting arm 31. A pivot shaft 212 is provided at the end of the first connecting arm 21, and the first massage head 22 is pivotally mounted on the pivot shaft 212 to achieve rolling massage.

[0091] In one embodiment, as shown in FIG. 1-3 and FIG. 5 , a plurality of first massage heads 22 are connected to the first connecting arm 21 at intervals, and / or a plurality of second massage heads 32 are connected to the second connecting arm 31 at intervals.

[0092] In this embodiment, the first massage head 22 and the second massage head 32 can be provided in multiple numbers as needed to meet different massage needs.

[0093] In this application, a plurality refers to two or more.

[0094] As shown in FIG11 , a massage mechanism provided in one embodiment of the present application includes a drive motor 9 and a massage assembly as described in any of the aforementioned embodiments. The drive motor 9 is in transmission connection with a transmission shaft 1. A set of yaw drive members 4, a first massage element 2, and a second massage element 3 are mounted on each end of the transmission shaft 1.

[0095] The massage mechanism provided in this application is a component of a massager, which includes a drive motor 9 and a massage component. The drive motor 9 is connected to the transmission shaft 1, and the drive motor 9 drives the transmission shaft 1 to rotate.

[0096] For the structure, construction and working principle of the massage component, please refer to the previous description of the massage component, which will not be repeated here.

[0097] The driving motor 9 can be a stepper motor or a servo motor.

[0098] A yaw drive 4 is mounted on each end of the drive shaft 1. Each yaw drive 4 is equipped with a set of first and second massage elements 2 and 3. The first massage elements 2 at each end yaw synchronously, providing a pinching and kneading massage. The second massage elements 3 at each end also yaw synchronously, providing a pinching and kneading massage.

[0099] The massage mechanism provided in this application is preferably applicable to a shoulder and neck massager. The transmission shaft 1 is connected to the housing of the massager through a support member, and the drive motor 9 is installed in the housing of the massager.

[0100] In one embodiment, as shown in FIG11 , a first gear set 10 is connected between the drive motor 9 and the transmission shaft 1 .

[0101] The input end gear of the first gear set 10 is connected to the output end of the drive motor 9 , and the output end gear of the first gear set 10 is connected to the transmission shaft 1 .

[0102] In this embodiment, the torque is transmitted through the first gear set 10 , and the torque transmission is stable without slipping, which is beneficial to the stable rotation of the transmission shaft 1 .

[0103] In one embodiment, as shown in FIG11 , the output end of the driving motor 9 is connected to a worm 91 , and the worm 91 is arranged parallel to the transmission shaft 1 .

[0104] The first gear set 10 includes a worm gear 101 , a first gear 102 coaxially arranged with the worm gear 101 , a second gear 103 meshing with the first gear 102 , a first bevel gear 104 provided on the second gear 103 , and a second bevel gear 105 meshing with the first bevel gear 104 .

The combination of two bevel gears can achieve torque transmission steering, so that the worm 91 is arranged parallel to the transmission shaft 1, which helps to reduce the height of the structure and thus reduce the thickness of the massager housing.

[0107] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0108] The above are only the principles and preferred embodiments of the present application.
