[0050] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0051] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0052] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0053] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0054] like Figures 1 to 15 As shown, according to an embodiment of this application, a massage device 100 is proposed. The massage device 100 includes a drive mechanism 20 and a massage mechanism 10. The drive mechanism 20 includes a drive member 21, and a first shaft 22, a second shaft 23 and an adjustment component 24 that are respectively capable of being transmitted and connected to the drive member 21. The massage mechanism 10 includes at least one massage component 11.

[0055] The following explanation uses two massage components (11) as an example:

[0056] Two massage components 11 are respectively mounted on the first shaft 22 and are drivenly connected to the first shaft 22. The two massage components 11 are drivenly connected to the second shaft 23. Each massage component 11 is drivenly connected to an adjustment component 24. Under the drive of the adjustment component 24, the two massage components 11 can move along the axial direction of the first shaft 22 and move closer or further away from each other. The massage component 11 includes a first massage element 111 and a second massage element 112.

[0057] Driven by the first axis 22, the first massage member 111 and the second massage member 112 can swing relative to the first axis 22 at a first frequency (in this application, the first massage member 111 can swing in the circumferential direction and the axial direction of the first axis 22, and the second massage member 112 can swing in the circumferential direction of the first axis 22). Driven by the second axis 23, the first massage member 111 and / or the second massage member 112 can swing relative to the first axis 22 at a second frequency (in this application, the components driven by the second axis 23 (the first massage member 111 and / or the second massage member 112) swing in the circumferential direction of the first axis 22) and are used to tap the user's body parts. The second frequency is greater than the first frequency.

[0058] Specifically, the drive component 21 outputs driving force to the outside. The first shaft 22 can be connected to or disconnected from the drive component 21. At the same time, the second shaft 23 can be connected to or disconnected from the drive component 21. That is, by controlling the drive component 21 to selectively connect to at least one of the first shaft 22 and the second shaft 23, the different modes of the massage device 100 can be switched.

[0059] Each massage component 11 has a first massage element 111 and a second massage element 112 respectively mounted on a first shaft 22 and connected to the first shaft 22 via a transmission. Taking the first massage element 111 as a neck massage element and the second massage element 112 as a shoulder massage element as an example, the first massage element 111 performs a massage action on the user's neck, and the second massage element 112 performs a massage action on the user's shoulders.

[0060] The first massage element 111 and the second massage element 112 are arranged adjacent to each other. Driven by the first axis 22, both move synchronously with the first axis 22. Simultaneously, driven by the second axis 23, at least one of them moves synchronously with the second axis 23. The following explanation uses the example where both the first massage element 111 and the second massage element 112 can be driven by the second axis 23.

[0061] The first massage component 111 includes a drive frame and a massage ball head. One end of the drive frame is connected to the massage ball head, and the other end of the drive frame is connected to the first shaft 22 and the second shaft 23 respectively. When the first shaft 22 is driven, one end of the drive frame drives the massage ball head to swing in the axial direction of the first shaft 22 and in the circumferential direction of the first shaft 22. In both swing directions, the swinging motion is a reciprocating motion, and the swing angle is less than 90°.

[0062] The second massage component 112 includes a drive arm and a massage head. One end of the drive arm is connected to the massage head, and the other end of the drive arm is connected to the first shaft 22 and the second shaft 23 respectively. When the first shaft 22 is driven, one end of the drive arm drives the massage head to swing in the circumferential direction of the first shaft 22. The swinging motion is a reciprocating motion, and the swinging angle is less than 90°.

[0063] When the driving member 21 drives the first massage member 111 and the second massage member 112 via the first shaft 22, both the first massage member 111 and the second massage member 112 oscillate in the circumferential direction of the first shaft 22 at a first frequency. When the driving member 21 drives the first massage member 111 and the second massage member 112 via the second shaft 23, both the first massage member 111 and the second massage member 112 oscillate in the circumferential direction of the first shaft 22 at a second frequency. The second frequency is greater than the first frequency. At the first frequency, the first massage member 111 and the second massage member 112 reciprocate fewer times in the circumferential direction of the first shaft 22 per unit time. At the second frequency, the first massage member 111 and the second massage member 112 reciprocate more times in the circumferential direction of the first shaft 22 per unit time. The aforementioned first frequency and second frequency are changes brought about by the driving member 21 moving at the same rotation speed. Through this change, the user can feel the tapping massage action and the changes in different massage rhythms, thereby meeting the user's usage needs and improving the user experience.

[0064] It is important to understand that the two massage components 11 are respectively mounted on the first shaft 22. Each massage component 11 is connected to the drive component 21 via an adjustment component 24. Driven by the drive component 21, the adjustment component 24 can adjust the position of the massage component 11 along the axial direction of the first shaft 22. By adjusting the position of the two massage components 11, a simultaneous movement and massage effect is achieved, expanding the massage range and meeting the needs of users with different body types, thereby further enhancing the user experience. Figure 2 and Figure 3 As shown, Figure 2 In the middle, the distance between the two massage components 11 is the first distance a. Figure 3 In the process, the distance between the two massage components 11 is the second distance b, where the first distance a is greater than the second distance b. The distance between the two massage components 11 can be adjusted to meet the usage needs of different users.

[0065] In addition, the adjustment component 24 can adjust the massage component 11 to a fixed position, in which the massage component 11 massages the user. The adjustment component 24 can also reciprocate the position of the massage component 11 along the axial direction of the first axis 22 while the massage component 11 is running, thereby increasing the massage area of ​​the massage device and further improving the user experience.

[0066] Furthermore, in this application, the first shaft 22 and the second shaft 23 are arranged parallel to each other and spaced apart. Arranging the first shaft 22 and the second shaft 23 parallel to each other and spaced apart facilitates the overall layout of the drive mechanism 20.

[0067] In some embodiments of this application, such as Figures 2 to 4 As shown, the drive mechanism 20 also includes two sliding seats 29 and two eccentric components 291. Each adjustment component 24 is driven to one sliding seat 29. The adjustment component 24 can drive the sliding seat 29 to move along the axial direction of the first shaft 22. The two eccentric components 291 are respectively arranged on the first shaft 22 and rotate synchronously with the first shaft 22. Each eccentric component 291 is driven to one sliding seat 29 and moves along the axial direction of the first shaft 22 under the drive of the sliding seat 29. The first massage element 111 and the second massage element 112 in each massage component 11 are driven to the same eccentric component 291.

[0068] Specifically, the eccentric component 291 is disposed on the first shaft 22. Along the axial direction of the first shaft 22, the eccentric component 291 can move relative to the first shaft 22. Along the circumferential direction of the first shaft 22, the eccentric component 291 rotates synchronously with the first shaft 22. The sliding seat 29 is connected to the adjusting component 24 and the eccentric component 291 respectively.

[0069] When the position of the massage component 11 needs to be adjusted, the drive component 21 drives the adjustment component 24, which in turn drives the sliding seat 29, causing the sliding seat 29 to move along the axial direction of the first axis 22. During the movement, the sliding seat 29 drives the eccentric component 291, which in turn drives the massage component 11 to adjust its position along the axial direction of the first axis 22. This achieves the adjustment of the positions of the first massage component 111 and the second massage component 112, thereby effectively adapting to different users and significantly improving the user experience.

[0070] It should be understood that when the first shaft 22 drives the eccentric assembly 291 to rotate synchronously, the eccentric assembly 291 drives the first massage member 111 and the second massage member 112 respectively, causing the first massage member 111 to swing in the axial direction and the circumferential direction of the first shaft 22, and causing the second massage member 112 to swing in the circumferential direction of the first shaft 22.

[0071] It should be noted that the eccentric component 291 is provided with a through hole, through which the first shaft 22 passes. A groove is provided on the wall of the through hole, which extends along the axial direction of the first shaft 22 and communicates with the two openings of the through hole. A protruding structure (such as a protrusion) is provided on the outer peripheral wall of the first shaft 22. The protruding structure is embedded in the groove. Along the axial direction of the first shaft 22, the protruding structure can slide relative to the groove so that the adjusting component 24 can adjust the position of the eccentric component 291 through the sliding seat 29. Along the circumferential direction of the first shaft 22, the protruding structure abuts against the side wall of the groove, and the first shaft 22 can drive the eccentric component 291 to rotate synchronously.

[0072] In addition, such as Figure 7 and 11 As shown, the eccentric component 291 is provided with an annular groove 2913, which surrounds the rotation axis of the eccentric component 291. A raised rib structure 2901 is provided on the sliding seat 29, embedded within the annular groove 2913, and spaced apart from the inner wall of the annular groove 2913. When the first shaft 22 drives the eccentric component 291 to rotate, the annular groove 2913 slides relative to the raised rib structure 2901. When the adjusting component 24 adjusts the position of the massage component 11, the driving component 21 drives the adjusting component 24, causing the sliding seat 29 to move along the axial direction of the first shaft 22. The raised rib structure 2901 abuts against the side wall of the annular groove 2913 and drives the eccentric component 291 to move along the axial direction of the first shaft 22, thereby adjusting the position of the massage component 11 through the movement of the eccentric component 291.

[0073] In addition, a position detection element (such as a Hall sensor) is installed on each sliding seat 29. The position detection element can effectively detect the current position of the massage component 11, thereby improving the accuracy of position adjustment of the massage component 11.

[0074] In some embodiments of this application, such as Figure 1 and Figure 4 As shown, the adjustment assembly 24 includes two adjustment rods 241 and two mating parts 242. The two adjustment rods 241 are respectively connected to the drive member 21. Each sliding seat 29 is provided with a mating part 242. The adjustment rods 241 are connected to the mating parts 242 so as to drive the mating parts 242 to move the sliding seat 29 along the axial direction of the first shaft 22.

[0075] Specifically, the mating part 242 is fixed on the sliding seat 29 and is connected to the adjusting rod 241 in a transmission manner. When it is necessary to adjust the position of the massage component 11, the driving part 21 drives the adjusting rod 241, the adjusting rod 241 drives the mating part 242, and the mating part 242 drives the sliding seat 29 to move along the axial direction of the first shaft 22. The sliding seat 29 drives the massage component 11 to move along the axial direction of the first shaft 22 through the eccentric component 291, thereby realizing the adjustment of the position of the massage component 11.

[0076] It should be understood that when the adjusting rod 241 drives the mating part 242, the mating part 242 moves along the axial direction of the first shaft 22 so as to drive the sliding seat 29 to move along the axial direction of the first shaft 22 through the mating part 242.

[0077] It should be noted that the mating part 242 is fixedly connected to the sliding seat 29, and the connection between the two is not limited to welding, snap-fitting, bonding or connection through a connector.

[0078] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the adjusting rod 241 has a first sliding groove 2411, which is a spiral groove provided on the outer peripheral wall of the adjusting rod 241. Part of the body of the mating part 242 is slidably disposed in the first sliding groove 2411.

[0079] Specifically, a through hole is provided on the sliding seat 29, and the mating part 242 is fixed on the sliding seat 29. The mating part 242 protrudes from the inner wall of the through hole. The adjusting rod 241 is arranged parallel to and spaced apart from the first shaft 22, and part of the adjusting rod 241 passes through the through hole. Both ends of the adjusting rod 241 protrude from the through hole. The part of the mating part 242 protruding from the inner wall of the through hole is embedded in the first sliding groove 2411, and the mating part 242 can slide relative to the first sliding groove 2411.

[0080] When the position of the massage component 11 needs to be adjusted, the drive member 21 drives the adjustment rod 241 to rotate. Since the first groove 2411 is a spiral groove and is formed on the outer peripheral wall of the adjustment rod 241, the spiral groove rotates with the adjustment rod 241. The rotating spiral groove drives the mating member 242, and drives the sliding seat 29 to move along the axial direction of the first shaft 22 through the mating member 242. The sliding seat 29 drives the massage component 11 to move along the axial direction of the first shaft 22 through the eccentric component 291, thereby realizing the adjustment of the position of the massage component 11.

[0081] In some embodiments of this application, such as Figure 6As shown, the first groove 2411 includes a first spiral portion 24111 and a second spiral portion 24112 with different directions of rotation. One end of the first spiral portion 24111 is smoothly connected to one end of the second spiral portion 24112, and the other end of the first spiral portion 24111 is smoothly connected to the other end of the second spiral portion 24112.

[0082] Specifically, the first spiral portion 24111 is formed on the outer peripheral wall of the adjusting rod 241, and the second spiral portion 24112 is also formed on the outer peripheral wall of the adjusting rod 241. The first spiral portion 24111 and the second spiral portion 24112 have different directions of rotation. The two ends of the first spiral portion 24111 are smoothly connected to the two ends of the second spiral portion 24112, respectively. Partial fitting 242 is embedded in the first spiral portion 24111 or the second spiral portion 24112.

[0083] When the driving member 21 drives the adjusting rod 241 to rotate, the first sliding groove 2411 of the spiral groove rotates synchronously with the adjusting rod 241. The spiral groove drives the mating member 242, causing the mating member 242 to move relative to the spiral groove along the axial direction of the first shaft 22. When the adjusting rod 241 rotates in one direction, the mating member 242 moves in the first direction as it slides in the first spiral portion 24111. When the mating member 242 slides from the first spiral portion 24111 to the second spiral portion 24112, it moves in the second direction. The first direction and the second direction are opposite. By alternatingly sliding the mating member 242 in the first spiral portion 24111 and the second spiral portion 24112, the massage component 11 reciprocates along the axial direction of the first shaft 22, thereby increasing the massage range of the massage component 11 and improving the user experience.

[0084] It should be understood that the driving component 21 drives the two adjustment components 24 respectively, and the two adjustment components 24 adjust the position of the two massage components 11 on the first axis 22 respectively. When the driving component 21 drives the two adjustment components 24 respectively, the two massage components 11 move closer to each other or further away from each other along the axial direction of the first axis 22.

[0085] In some embodiments of this application, such as Figure 11 As shown, the driving component 21 includes a driving shaft 211, which includes a first driving end, which is a first worm 2111. The driving mechanism 20 includes a first worm gear set 25, which includes two first worm gears 251. The two first worm gears 251 mesh with the first worm 2111 respectively. The two adjusting components 24 are drivenly connected to the same first worm gear 251. The first shaft 22 is drivenly connected to the other first worm gear 251.

[0086] Specifically, the first driving end of the driving component 21 drives the two adjusting components 24 respectively. The first driving end of the first worm 2111 is connected to the adjusting component 24 through the first worm wheel 251. The worm wheel and worm gear transmission structure is compact and can effectively reduce the space occupied. In addition, the worm wheel and worm gear transmission structure has high transmission efficiency and can effectively reduce energy consumption.

[0087] In some embodiments of this application, such as Figure 4 and Figure 11 As shown, the first worm gear assembly 25 also includes two first transmission gears 252. Each adjusting rod 241 is equipped with a first transmission gear 252 for transmission connection. The first worm gear 251 on the adjusting assembly 24 includes a first worm gear part 2511 and two first gear parts 2512 coaxially connected. The two first gear parts 2512 are respectively located at the two axial ends of the first worm gear part 2511. The first worm gear part 2511 meshes with the first worm 2111, and each first transmission gear 252 meshes with one first gear part 2512.

[0088] Specifically, a through hole is provided on the sliding seat 29, and a mating part 242 is fixed on the sliding seat 29. The mating part 242 protrudes from the inner wall of the through hole. The adjusting rod 241 is arranged parallel to and spaced apart from the first shaft 22, and part of the adjusting rod 241 passes through the through hole. The part of the mating part 242 protruding from the inner wall of the through hole is embedded in the first sliding groove 2411, and the mating part 242 can slide relative to the first sliding groove 2411. Both ends of the adjusting rod 241 protrude from the through hole. A first transmission gear 252 is fitted and fixed at one end of the adjusting rod 241, and a limiting component is provided at the other end of the adjusting rod 241. The first sliding groove 2411 is opened between the first transmission gear 252 and the limiting component. This arrangement can reduce the possibility of the adjusting rod 241 separating from the sliding seat 29, thereby improving the reliability of the massage device 100.

[0089] It should be understood that the first worm wheel 2511 of the first worm wheel 251 meshes with the first worm 2111, and the first gear 2512 of the first worm wheel 251 meshes with the first transmission gear 252. By setting the gear ratio between the first gear 2512 and the first transmission gear 252, the rotation speed of the adjusting rod 241 can meet the usage requirements, thereby effectively realizing the adjustment of the position of the massage component 11.

[0090] In some embodiments of this application, such as Figure 4 and Figure 11As shown, the first worm gear assembly 25 also includes a second transmission gear 253, which is mounted on the first shaft 22. The first worm gear 251 for driving the first shaft 22 includes a first worm gear portion 2511 and a first gear portion 2512 coaxially connected, and the first gear portion 2512 meshes with the second transmission gear 253.

[0091] Specifically, the second transmission gear 253 is mounted and fixed on the first shaft 22. The second transmission gear 253 meshes with the first gear part 2512 of the first worm gear 251. With this configuration, the drive mechanism 20 can be simplified while realizing the transmission connection between the drive component 21 and the first shaft 22, thereby effectively reducing the volume of the overall structure and also effectively reducing the manufacturing cost.

[0092] It should be understood that by setting the gear ratio between the second transmission gear 253 and the first gear 2512, the rotation speed of the first shaft 22 is made to meet the usage requirements, thereby effectively driving the position of the massage component 11.

[0093] In some embodiments of this application, the first worm gear assembly 25 further includes a first one-way bearing, and the first transmission gear 252 is mounted on the adjusting rod 241 via the first one-way bearing.

[0094] Specifically, the first transmission gear 252 is mounted on the adjusting rod 241 via a first one-way bearing. By controlling the rotation direction of the first transmission gear 252, the transmission between the first transmission gear 252 and the adjusting rod 241 can be controlled or disengaged. For example, when the first transmission gear 252 rotates clockwise, the first one-way bearing is locked, and the first transmission gear 252 and the adjusting rod 241 rotate synchronously (at this time, the adjusting rod 241 can be driven by the first transmission gear 252). When the first transmission gear 252 rotates counterclockwise, the first one-way bearing is open, and the first transmission gear 252 rotates relative to the adjusting rod 241 (at this time, the adjusting rod 241 cannot be driven by the first transmission gear 252).

[0095] In some embodiments of this application, the first worm gear assembly 25 further includes a second one-way bearing, and the second transmission gear 253 is mounted on the first shaft 22 via the second one-way bearing.

[0096] Specifically, the second transmission gear 253 is mounted on the first shaft 22 via a second one-way bearing. By controlling the rotation direction of the second transmission gear 253, the transmission between the second transmission gear 253 and the first shaft 22 can be initiated or disengaged. For example, when the second transmission gear 253 rotates clockwise, the second one-way bearing is locked, and the second transmission gear 253 rotates synchronously with the first shaft 22 (at this time, the first shaft 22 can be driven by the second transmission gear 253). When the second transmission gear 253 rotates counterclockwise, the second one-way bearing is open, and the second transmission gear 253 rotates relative to the first shaft 22 (at this time, the adjusting rod 241 cannot be driven by the second transmission gear 253).

[0097] In some embodiments of this application, such as Figure 7 As shown, the eccentric assembly 291 includes a wheel body 2911 and an eccentric portion 2912. The wheel body 2911 is mounted on the first shaft 22 and connected to the eccentric portion 2912 along the axial direction of the first shaft 22. The eccentric portion 2912 is rotatably connected to the second massage member 112. The drive mechanism 20 also includes two first guide seats 292. The first guide seats 292 are provided with a first guide structure 2921, and the second massage member 112 is provided with a second guide structure 1121. The first guide structure 2921 and the second guide structure 1121 are guided and engaged so that the second massage member 112 can swing in the circumferential direction of the first shaft 22.

[0098] Specifically, the second massage component 112 includes a drive arm and a massage head. One end of the drive arm is connected to the massage head, and the other end of the drive arm is fitted onto an eccentric portion 2912. The eccentric portion 2912 can rotate relative to the drive arm. At the same time, a second guide structure 1121 is provided at the end of the drive arm away from the massage head. A first guide seat 292 is provided on the side of the drive arm away from the massage head, and the first guide structure 2921 on the first guide seat 292 cooperates with the second guide structure 1121.

[0099] When the first shaft 22 rotates, the wheel 2911 drives the eccentric part 2912 to rotate eccentrically. The eccentric part 2912 drives the drive arm. Through the cooperation of the first guide structure 2921 and the second guide structure 1121, the drive arm causes the massage head to swing in the circumferential direction of the first shaft 22.

[0100] It should be noted that in this application, the first guide structure 2921 is a first guide groove provided on the first guide seat 292, and the second guide structure 1121 is a first protrusion formed on the drive arm. The first protrusion is located in the first guide groove. In the circumferential direction of the first shaft 22, the first guide groove provides a swing stroke for the first protrusion. Within the swing stroke, the first protrusion can swing relative to the first guide groove. Through the drive of the drive arm by the eccentric part 2912 and the cooperation of the first guide structure 2921 and the second guide structure 1121, the second massage member 112 swings in the circumferential direction of the first shaft 22 under the drive of the first shaft 22.

[0101] In some embodiments of this application, such as Figure 7 As shown, the eccentric assembly 291 further includes a connecting portion 294, which is fixedly connected to the eccentric portion 2912. The connecting portion 294 includes a driving portion, the axis of which is set at an angle to the axis of the first shaft 22 (e.g., Figure 7 As shown, Figure 7 The axis of the drive part and the axis of the first shaft 22 form a preset angle c. The first massage member 111 is rotatably mounted on the drive part. The drive mechanism 20 also includes two second guide seats 293. Each first massage member 111 corresponds to a second guide seat 293. The second guide seat 293 is provided with a third guide structure 2931. The first massage member 111 is provided with a fourth guide structure 1111. The third guide structure 2931 and the fourth guide structure 1111 guide and cooperate to enable the first massage member 111 to swing on the first shaft 22.

[0102] Specifically, the first massage component 111 includes a drive frame and a massage ball head. One end of the drive frame is connected to the massage ball head, and the other end of the drive frame is fitted onto the drive portion of the connecting part 294. The drive portion can rotate relative to the drive frame. Meanwhile, the other end of the drive frame is provided with a fourth guide structure 1111. A second guide seat 293 is provided on the side of the drive frame away from the massage ball head, and a third guide structure 2931 on the second guide seat 293 cooperates with the fourth guide structure 1111.

[0103] When the first shaft 22 rotates, the wheel 2911 drives the eccentric part 2912 to rotate eccentrically. The eccentric part 2912 drives the connecting part 294 to rotate. As the connecting part 294 rotates with the eccentric part 2912, the driving part rotates relative to the driving frame and drives the driving frame. By setting the axis of the driving part at an angle to the axis of the first shaft 22, and by cooperating with the third guide structure 2931 and the fourth guide structure 1111, the driving frame drives the massage ball head to swing in the axial direction and circumferential direction of the first shaft 22, so that the massage ball head can perform massage actions on the user.

[0104] It should be noted that in this application, the third guide structure 2931 is a second guide groove provided on the second guide seat 293, and the fourth guide structure 1111 is a second protrusion formed on the drive arm. The second protrusion is located in the second guide groove. In both the circumferential and axial directions of the first shaft 22, the second guide groove provides a swing stroke for the second protrusion. Within the swing stroke, the second protrusion can swing relative to the second guide groove. By setting the axis of the drive part at an angle to the axis of the first shaft 22, and by cooperating with the third guide structure 2931 and the fourth guide structure 1111, the drive frame drives the massage ball head to swing in both the axial and circumferential directions of the first shaft 22, so that the massage ball head can perform massage actions on the user.

[0105] In addition, the connecting part 294 is connected and fixed to the eccentric part 2912 of the eccentric component 291. The connection methods between the two include, but are not limited to, bonding, snap-fitting, welding or connection via connectors.

[0106] An end cap 295 is provided on the outside of the connecting part 294. The end cap 295 is connected to the connecting part 294 and limits the drive frame to be installed on the drive part of the connecting part 294.

[0107] In some embodiments of this application, such as Figure 1 As shown, the drive mechanism 20 also includes an eccentric drive assembly 28, and the second shaft 23 is connected to a massage assembly 11 via an eccentric drive assembly 28.

[0108] Specifically, the eccentric drive assembly 28 is connected to the second shaft 23 and the massage assembly 11 respectively. When the user needs the massage assembly 11 to perform a tapping action, the drive member 21 drives the second shaft 23. The rotation of the second shaft 23 drives the eccentric drive assembly 28 to move. The eccentric drive assembly 28 drives the massage assembly 11, causing the first massage member 111 and the second massage member 112 of the massage assembly 11 to swing at a second frequency in the circumferential direction of the first shaft 22, thereby realizing the tapping massage for the user, meeting the user's needs, and thus improving the user experience.

[0109] In some embodiments of this application, such as Figure 4 , Figure 11 and Figure 12 As shown, the eccentric drive assembly 28 includes an eccentric wheel 281 and a connecting rod 282. The eccentric wheel 281 is mounted on the second shaft 23, and the axis of the eccentric wheel 281 is parallel to and spaced apart from the axis of the second shaft 23. One end of the connecting rod 282 is rotatably mounted on the eccentric wheel 281, and the other end of the connecting rod 282 is connected to at least one of the first guide seat 292 and the second guide seat 293.

[0110] Specifically, the massage assembly 11 is mounted on the first shaft 22. The first protrusion of the second massage member 112 of the massage assembly 11 is located in the first guide groove of the first guide seat 292, and the second protrusion of the first massage member 111 is located in the second guide groove of the second guide seat 293. An eccentric wheel 281 is fixedly mounted on the second shaft 23. One end of a connecting rod 282 is mounted on the eccentric portion 2912 of the eccentric wheel 281, and the connecting rod 282 is rotatable relative to the eccentric portion 2912 of the eccentric wheel 281. The other end of the connecting rod 282 is rotatably connected to at least one of the first guide seat 292 and the second guide seat 293.

[0111] Taking the other end of the connecting rod 282 as being connected to both the first guide seat 292 and the second guide seat 293, when the second shaft 23 drives the eccentric wheel 281 to rotate, the eccentric part 2912 of the eccentric wheel 281 drives the connecting rod 282 to move. The other end of the connecting rod 282 drives the first guide seat 292 and the second guide seat 293 to reciprocate. The reciprocating directions of the first guide seat 292 and the second guide seat 293 are perpendicular to the first shaft 22 and the second shaft 23, respectively. Thus, the first guide groove of the first guide seat 292 and the first protrusion are used to drive the second massage member 112 to swing in the circumferential direction of the first shaft 22, and the second guide groove of the second guide seat 293 and the second protrusion are used to drive the second massage member 112 to swing in the circumferential direction of the first shaft 22.

[0112] In some embodiments of this application, such as Figures 7 to 8 As shown, the second shaft 23 drives both the first massage member 111 and the second massage member 112 through the eccentric drive assembly 28. The first guide seat 292 is slidably connected to the sliding seat 29, the second guide seat 293 is fixed on the first guide seat 292, and the other end of the connecting rod 282 is rotatably connected to the first guide seat 292 or the second guide seat 293.

[0113] Specifically, the sliding seat 29 has an elongated hole, and the first guide seat 292 has two through holes. A bolt passes through each through hole, and each bolt passes through the elongated hole and is connected to a nut, thereby allowing the first guide seat 292 and the sliding seat 29 to be slidably connected. The connecting rod 282 is connected to the first guide seat 292 or the second guide seat 293 via a pin 296, and the connecting rod 282 can rotate relative to the pin 296.

[0114] When the second shaft 23 drives the eccentric wheel 281 to rotate, the eccentric part 2912 of the eccentric wheel 281 drives the connecting rod 282 to move. The other end of the connecting rod 282 rotates relative to the pin 296, and the elongated hole guides the bolt, so that the first guide seat 292 and the second guide seat 293 slide back and forth relative to the sliding seat 29. The first guide groove of the first guide seat 292 and the first protrusion are used to drive the second massage member 112 to swing in the circumferential direction of the first shaft 22, and the second guide groove of the second guide seat 293 and the second protrusion are used to drive the second massage member 112 to swing in the circumferential direction of the first shaft 22.

[0115] In some embodiments of this application, the second shaft 23 drives the first massage member 111 or the second massage member 112 through the eccentric drive assembly 28, wherein the first guide seat 292 is slidably connected to the sliding seat 29, the second guide seat 293 is slidably connected to the first guide seat 292, and the other end of the connecting rod 282 is rotatably connected to the first guide seat 292 or the second guide seat 293.

[0116] Specifically, the sliding seat 29 has an elongated hole, and the first guide seat 292 has two through holes. A bolt passes through each through hole, and each bolt passes through the elongated hole and is connected to a nut, thereby allowing the first guide seat 292 and the sliding seat 29 to be slidably connected. The connecting rod 282 is connected to the first guide seat 292 or the second guide seat 293 via a pin 296, and the connecting rod 282 can rotate relative to the pin 296.

[0117] The sliding connection between the first guide seat 292 and the second guide seat 293 is the same as the sliding connection between the sliding seat 29 and the first guide seat 292.

[0118] When the connecting rod 282 drives only the second massage member 112, the other end of the connecting rod 282 is connected to the first guide seat 292 via the pin 296. When the second shaft 23 drives the eccentric wheel 281 to rotate, the eccentric part 2912 of the eccentric wheel 281 drives the connecting rod 282 to move. The other end of the connecting rod 282 rotates relative to the pin 296, and the elongated hole guides the bolt, so that the first guide seat 292 slides back and forth relative to the second guide seat 293 and the sliding seat 29, respectively. Thus, the first guide groove of the first guide seat 292 and the first protrusion are used to drive the second massage member 112 to swing in the circumferential direction of the first shaft 22.

[0119] When the connecting rod 282 drives only the first massage member 111, the other end of the connecting rod 282 is connected to the second guide seat 293 via the pin 296. When the second shaft 23 drives the eccentric wheel 281 to rotate, the eccentric part 2912 of the eccentric wheel 281 drives the connecting rod 282 to move. The other end of the connecting rod 282 rotates relative to the pin 296, and the elongated hole guides the bolt, so that the second guide seat 293 slides back and forth relative to the first guide seat 292. Thus, the first massage member 111 is driven to swing in the circumferential direction of the first shaft 22 by the cooperation between the second guide groove and the second protrusion of the second guide seat 293.

[0120] In some embodiments of this application, the second shaft 23 drives both the first massage member 111 and the second massage member 112 via the eccentric drive assembly 28. The first guide seat 292 is slidably connected to the sliding seat 29, and the second guide seat 293 is slidably connected to the first guide seat 292. There are two connecting rods 282; the first guide seat 292 is rotatably connected to the other end of one connecting rod 282, and the second guide seat 293 is rotatably connected to the other end of the other connecting rod 282.

[0121] Specifically, the sliding seat 29 has an elongated hole, and the first guide seat 292 has two through holes. A bolt passes through each through hole, and each bolt passes through the elongated hole and is connected to a nut, thereby allowing the first guide seat 292 and the sliding seat 29 to be slidably connected. The connecting rod 282 is connected to the first guide seat 292 or the second guide seat 293 via a pin 296, and the connecting rod 282 can rotate relative to the pin 296.

[0122] The sliding connection between the first guide seat 292 and the second guide seat 293 is the same as the sliding connection between the sliding seat 29 and the first guide seat 292.

[0123] One end of each of the two connecting rods 282 is rotatably connected to the eccentric portion 2912 of the eccentric wheel 281. The other end of one connecting rod 282 is connected to the first guide seat 292 via a pin 296, and the other end of the other connecting rod 282 is connected to the second guide seat 293 via a pin 296. When the second shaft 23 drives the eccentric wheel 281 to rotate, the eccentric portion 2912 of the eccentric wheel 281 drives the connecting rod 282 to move. The other ends of the two connecting rods 282 rotate relative to the pin 296 connected to them, and the elongated hole guides the bolt. The first guide seat 292 slides relative to the sliding seat 29 and the second guide seat 293, respectively. Thus, the first guide groove of the first guide seat 292 and the first protrusion are used to drive the second massage member 112 to swing in the circumferential direction of the first shaft 22, and the second guide groove of the second guide seat 293 and the second protrusion are used to drive the first massage member 111 to swing in the circumferential direction of the first shaft 22.

[0124] In some embodiments of this application, the eccentric drive assembly 28 further includes a one-way bearing component, and the eccentric wheel 281 is mounted on the second shaft 23 via at least one one-way bearing component.

[0125] Specifically, the eccentric wheel 281 is mounted on the second shaft 23 via a one-way bearing component. By controlling the rotation direction of the second shaft 23, the transmission or discontinuation of the transmission between the second shaft 23 and the eccentric wheel 281 can be achieved. For example, when the second shaft 23 rotates clockwise, the one-way bearing component is locked, and the second shaft 23 and the eccentric wheel 281 rotate synchronously (at this time, the eccentric wheel 281 can be driven by the second shaft 23). When the second shaft 23 rotates counterclockwise, the one-way bearing component is open, and the second shaft 23 rotates relative to the eccentric wheel 281 (at this time, the eccentric wheel 281 cannot be driven by the second shaft 23).

[0126] In some embodiments of this application, such as Figure 1 , Figure 4 , Figures 11 to 13 As shown, the drive mechanism 20 also includes a switch assembly 27. The drive member 21 and the second shaft 23 are respectively connected to the switch assembly 27 in a transmission manner. The switch assembly 27 includes an open state and a closed state. In the open state, the drive member 21 can drive the second shaft 23. In the closed state, the drive member 21 is disconnected from the second shaft 23 in a transmission manner.

[0127] Specifically, during use, the neck and shoulder device can control whether the second shaft 23 is connected to the drive component 21 via the switch component 27, so as to turn the tapping function of the massage component 11 on or off. That is, when using the tapping function, the switch component 27 is switched to the on state, and when the tapping function is not used, the switch component 27 is switched to the off state. This allows users to choose according to their different needs, thereby effectively improving the user experience.

[0128] In some embodiments of this application, such as Figure 1 , Figure 4 , Figures 11 to 13 As shown, the driving component 21 includes a driving shaft 211, which includes a second driving end, which is a second worm 2112. The driving mechanism 20 also includes a support base 297 and a second worm gear set 26. The second worm gear set 26 includes a second worm gear 263, a fourth transmission gear 262, and a fifth transmission gear 261. The second worm gear 263 is rotatably mounted on the support base 297 and meshes with the second worm 2112. The fourth transmission gear 262 is rotatably mounted on the support base 297. The fifth transmission gear 261 is fitted and fixed on the second shaft 23 and meshes with the fourth transmission gear 262.

[0129] The switch assembly 27 is movably mounted on the support base 297 and can switch between an open state and a closed state. In the open state, the second worm gear 263 is connected to the fourth transmission gear 262 via the switch assembly 27. In the closed state, the switch assembly 27 disconnects the transmission between the second worm gear 263 and the fourth transmission gear 262.

[0130] Specifically, in this application, the driving component 21 is a drive motor, which includes a drive shaft 211. The two opposite ends of the drive shaft 211 protrude relative to the driving component 21. One end of the drive shaft 211 is a first driving end, and the other end is a second driving end. The first driving end is a first worm gear 2111, which is connected to the adjusting component 24 and the first shaft 22 via a first worm gear set 25. The second driving end is a second worm gear 2112, which is connected to the second shaft 23 via a second worm gear set 26. Using a single driving component 21 to simultaneously drive the first shaft 22 and the second shaft 23 simplifies the structure, reduces manufacturing costs, and decreases the size, thereby improving the ease of layout and installation.

[0131] Furthermore, the switch assembly 27, the fourth transmission gear 262, and the second worm gear 263 are respectively mounted on the support base 297, and the second worm gear 263 and the fourth transmission gear 262 are rotatably mounted on the support base 297. The switch assembly 27 can move on the support base 297. The second worm gear 263 meshes with the second drive end of the drive member 21, which is the second worm 2112. The fifth transmission gear 261 is mounted and fixed on the second shaft 23 and meshes with the fourth transmission gear 262. By utilizing the movement of the switch assembly 27 relative to the support base 297, the second worm gear 263 and the fourth transmission gear 262 can drive or contact each other, thereby realizing the driving member 21 driving or releasing the second shaft 23.

[0132] When the switch assembly 27 moves relative to the support base 297 and switches to the open state, the second worm gear 263 and the fourth transmission gear 262 can transmit power. At this time, the drive member 21 drives the second worm gear 263 through the second drive end, the second worm gear 263, the fourth transmission gear 262 and the fifth transmission gear 261. When the switch assembly 27 moves relative to the support base 297 and switches to the closed state, the second worm gear 263 and the fourth transmission gear 262 are disconnected from each other. At this time, the drive member 21 drives the second worm gear 263 through the second drive end. The second worm gear 263 rotates on the support base 297 and cannot transmit power to the fourth transmission gear 262.

[0133] In this application, the second drive end of the second worm 2112 outputs power through the second worm wheel 263. The worm wheel and worm gear transmission structure is compact and can effectively reduce the space occupied. In addition, the worm wheel and worm gear transmission structure has high transmission efficiency and can effectively reduce energy consumption.

[0134] In this application, the first shaft 22 and the second shaft 23 are arranged parallel and spaced apart. The drive shaft 211 of the drive member 21 is perpendicular to both the first shaft 22 and the second shaft 23. The first shaft 22 is connected to the first drive end of the drive shaft 211 via a first worm gear set 25, and the second shaft 23 is connected to the second drive end of the drive shaft 211 via a second worm gear set 26 and a switch assembly 27. In the second worm gear set 26, both the fourth transmission gear 262 and the fifth transmission gear 261 are bevel gears. By setting both as bevel gears, the direction of power transmission is changed, thereby enabling the drive member 21 to effectively drive the second shaft 23.

[0135] In some embodiments of this application, such as Figures 13 to 15 As shown, the rotation axis of the second worm gear 263 is parallel and spaced apart from the rotation axis of the fourth transmission gear 262. The switch assembly 27 includes a control rod 271, a gear component 273, and at least one limiting member 272. The control rod 271 is movably mounted on the support base 297, and its opposite ends protrude from the support base 297. The control rod 271 is inserted into and coaxially arranged with the second worm gear 263. Along the axial direction of the second worm gear 263, the control rod 271 can move relative to the second worm gear 263. At least one limiting member 272 is provided on the control rod 271. The second worm gear 263 includes a receiving cavity 2631 with an opening. A limiting structure is provided on the side wall of 31. Part of the control rod 271 passes through the receiving cavity 2631. In the open state, at least one limiting member 272 enters the receiving cavity 2631 through the opening and cooperates with the limiting structure so that the control rod 271 rotates synchronously with the second worm gear 263. In the closed state, at least one limiting member 272 disengages from the receiving cavity 2631 through the opening so that the control rod 271 is disengaged from the second worm gear 263. The gear member 273 is provided on the outside of the support member and is fitted and fixed on one end of the control rod 271. The gear member 273 meshes with the fourth transmission gear 262. Along the axial direction of the fourth transmission gear 262, the gear member 273 can slide relative to the fourth transmission gear 262.

[0136] Specifically, the support 297 includes a base and a cover. The base has an installation space. The second worm gear 263 is rotatably disposed in the installation space. The cover covers the top of the installation space and closes the top opening of the installation space. One side wall of the installation space is an open structure. The second worm gear 263 meshes with the second drive end of the drive shaft 211 of the drive member 21 of the second worm 2112 through the open structure. The control rod 271 passes through the cover and the base. The two ends of the control rod 271 are located on the outside of the support 297. Inside the installation space, the control rod 271 passes through the receiving cavity 2631 of the second worm gear 263. The control rod 271 can move along the axial direction of the second worm gear 263. The end of the control rod 271 located on the outside of the support 297 is provided with a gear member 273, which meshes with the fourth transmission gear 262.

[0137] A limiting member 272 is mounted on the control rod 271, and a limiting structure is mounted on the side wall of the receiving cavity 2631. When the control rod 271 drives the limiting member 272 from the opening of the receiving cavity 2631 into the receiving cavity 2631 and engages with the mating structure, the control rod 271 locks with the second worm gear 263 in the circumferential direction (at this time, the switch assembly 27 is in the open state). At this time, the second worm gear 263 can drive the control rod 271 to rotate synchronously, and drive the fourth transmission gear 262 to rotate through the gear component 273. The rotation of the fourth transmission gear 262 drives the fifth gear to rotate, thereby driving the second shaft 23 to rotate. When the control rod 271 drives the limiting member 272 to disengage from the opening of the receiving cavity 2631, the limiting member 272 disengages from the mating structure (at this time, the switch assembly 27 is in the closed state), and the control rod 271 cannot transmit power with the second worm gear 263.

[0138] It should be noted that the axial direction of the fourth transmission gear 262 is consistent with the moving direction of the control lever 271. The fourth transmission gear 262 includes a bevel tooth portion 2621 and a straight tooth portion 2622 connected coaxially. The bevel tooth portion 2621 meshes with the fifth transmission gear 261, and the straight tooth portion 2622 meshes with the gear component 273. When the control lever 271 moves relative to the support base 297, the gear component 273 can slide relative to the straight tooth portion 2622.

[0139] In addition, a limiting element 272 is provided on the control lever 271, and the number of limiting elements 272 can be one, two, three, four, five or six, etc.

[0140] In some embodiments of this application, such as Figure 13As shown, the limiting structure is a limiting groove 2632 formed in the receiving cavity 2631. The limiting groove 2632 extends along the axial direction of the second worm gear 263. The limiting member 272 includes an elastic part 2721 and a limiting part 2722. The control rod 271 is provided with a receiving structure 2711 along the radial direction of the second worm gear 263. The elastic part 2721 is disposed in the receiving structure 2711. The limiting part 2722 abuts against the elastic part 2721. The rebound force of 1 causes the limiting part 2722 to tend to move in the direction of disengaging from the receiving structure 2711. In the open state, part of the limiting part 2722 is received in the receiving structure 2711, and another part of the limiting part 2722 is embedded in the limiting groove 2632. In the closed state, part of the limiting part 2722 is received in the receiving structure 2711, and another part of the limiting part 2722 is located on the outside of the receiving structure 2711 and abuts against the support base 297.

[0141] Specifically, in this application, the receiving structure 2711 is arranged in the radial direction through the control rod 271, the elastic part 2721 is a spring and is arranged inside the receiving structure 2711, the number of limiting parts 2722 is two and they are spherical, the two limiting parts 2722 respectively abut against opposite ends of the spring, and part of the body of the two limiting parts 2722 is located outside the receiving structure 2711.

[0142] When the switch assembly 27 is in the open state, such as Figure 14 As shown, the portion of the limiting part 2722 located outside the receiving structure 2711 is embedded in the limiting groove 2632 (the spring is in a compressed state). Along the axial direction of the second worm wheel 263, the limiting part 2722 and the limiting groove 2632 can slide relative to each other. Along the circumferential direction of the second worm wheel 263, the limiting part 2722 abuts against the side wall of the limiting groove 2632 and rotates synchronously with the second worm wheel 263.

[0143] When the switch assembly 27 is in the closed state, such as Figure 15 As shown, the portion of the limiting part 2722 located outside the receiving structure 2711 is separated from the limiting groove 2632 and abuts against the side wall of the receiving cavity 2631 of the seat (the spring is in a compressed state). At this time, the control rod 271 is disengaged from the second worm gear 263.

[0144] In this application, the limiting member 272 has a simple structure and can effectively lock or release the engagement with the second worm gear 263, thereby effectively controlling whether the drive member 21 and the second shaft 23 are in motion.

[0145] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
