Description

Technical Field

[0001] This disclosure relates to the field of health care device technology, and in particular to a connecting device and a massage device. Background Technology

[0002] Massage devices, as health care instruments to relieve or eliminate physical fatigue, are becoming increasingly popular due to their flexibility and convenience. To achieve better massage effects, targeted massage devices are usually designed according to the structural characteristics of different parts of the human body, such as neck massage devices, waist massage devices, and dual-area massage devices.

[0003] With increasingly sedentary work and lifestyles, people are prone to muscle discomfort, leading to a growing market demand for massage devices that can provide muscle massage. Some massage devices integrate multiple massage components, allowing adjustment of the spacing and / or angle between these components to suit different user needs. However, the complex transmission structure of these devices makes it difficult to independently adjust the massage range of each component to meet varying user preferences for massage intensity and / or range, thus hindering a better user experience. Utility Model Content

[0004] This disclosure provides a connecting device and a massage device. The connecting device can both control the movement of the massage components and adjust their relative positions, thereby improving the user experience of the massage device.

[0005] The technical solution is as follows:

[0006] According to a first aspect of the present disclosure, a connecting device is provided, including a mounting shell, an adjusting assembly, a connector, a first driving assembly, and a second driving assembly for driving a transmission cylinder to rotate. The mounting shell includes a first shell body. The adjusting assembly includes an adjusting shell and a transmission cylinder slidably connected to the first shell body. The adjusting shell and the transmission cylinder are rotatably connected, and the transmission cylinder has a through cavity. The connector is movably connected to the adjusting shell and has a connecting portion for connecting to a massage member. The first driving assembly includes a driving member rotatably disposed between the connector and the transmission cylinder, and a transmission rod rotatably disposed on the mounting shell. The driving member and the connector are driven together to move the connector. One end of the transmission rod passes through the through cavity and is driven together with the driving member to rotate the driving member. When the transmission cylinder rotates relative to the mounting shell, it can drive the adjusting shell to move relative to the first shell body.

[0007] The technical solution will be further explained below:

[0008] In one embodiment, the transmission cylinder includes a cylinder body and a first rotating ring fixed to the outer periphery of the cylinder body. A second drive assembly is used to drive the cylinder body to rotate. The first rotating ring is rotatably connected to the adjusting shell, and the first rotating ring is inclined, with the inclination direction of the first rotating ring intersecting the rotation axis of the transmission rod.

[0009] In one embodiment, the adjusting shell has a limiting cavity, which includes a limiting notch and a transmission notch opposite to the limiting notch. The connecting member includes a rotating part movably disposed within the limiting cavity. The rotating part is fixedly connected to the connecting part and engages with the limiting notch to prevent disengagement. The connecting part is exposed outside the limiting notch. A driving member is rotatably disposed within the limiting cavity and engages with the rotating part in a transmission manner. The driving member is rotatably disposed within the limiting cavity, and a first rotating ring is rotatably disposed within the limiting cavity and carries the driving member.

[0010] In one embodiment, the adjusting shell includes a second shell body with a limiting cavity and a cover plate with a transmission notch. The second shell body is fixedly connected to the cover plate. The second shell body also has a limiting notch. The cover plate carries a first rotating ring to prevent the first rotating ring from disengaging from the transmission notch.

[0011] In one embodiment, the second shell body is provided with an annular groove communicating with the limiting cavity. The first rotating ring shell is rotatably disposed in the annular groove and engages with the cover plate to prevent detachment.

[0012] In one embodiment, the drive member is provided with a second rotating ring rotatably disposed in an annular groove.

[0013] The sidewalls of the annular groove are provided with oil storage tanks.

[0014] In one embodiment, the connector includes a rotating portion fixedly connected to the connecting portion, the rotating portion being rotatably disposed within the limiting cavity. The connecting portion includes a connecting protrusion fixedly connected to the rotating portion, at least a portion of the connecting protrusion being disposed outside the limiting cavity through a limiting notch. The longitudinal direction of the connecting protrusion is not coaxial with the rotation axis of the transmission rod.

[0015] In one embodiment, the cylinder body is provided with an external thread structure, and the side wall of the limiting cavity is provided with an internal thread structure that engages with the external thread structure in a helical transmission.

[0016] In one embodiment, the connecting device further includes an angle detection component, which includes a trigger fixed to the cylindrical body and an angle detection module fixed to the first shell body. The trigger can trigger the angle detection module to generate an angle detection signal.

[0017] In one embodiment, the drive member is provided with a non-circular transmission hole communicating with the cavity, and one end of the transmission rod is engaged with the transmission hole.

[0018] In one embodiment, the transmission rod is non-cylindrical and is fitted with a transmission hole.

[0019] And / or, the end of the transmission rod is provided with an anti-rotation protrusion, and the side wall of the transmission hole is provided with an anti-rotation groove that slides with the anti-rotation protrusion.

[0020] In one embodiment, the mounting housing further includes a guide rail fixed to the first housing body, and the adjusting housing includes a guide portion that cooperates with the guide rail.

[0021] In one embodiment, the guide rail is provided with a guide groove, and at least a portion of the guide portion protrudes from the adjustment shell and is inserted into the guide groove.

[0022] In one embodiment, the second drive assembly includes a rotary power source, an active member that is driven by the rotating end of the rotary power source, and a driven member that is driven by the transmission cylinder on the same axis. The active member can drive the driven member to rotate.

[0023] According to a second aspect of the present disclosure, a massage device is also provided, including a support device, a power mechanism, a massage element, and a connecting device as described in any of the above embodiments. A mounting housing is fixed to the support device. The power mechanism is disposed on the support device and is drively connected to a transmission rod. The massage element is connected to the connecting portion.

[0024] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0025] During assembly, the connector and drive assembly are integrated into the adjustment assembly, allowing the connector to rotate relative to the adjustment shell and be connected to the transmission rod via the drive assembly. The mounting shell is then fixed to the support assembly, connected to the massage element via the connector, and connected to the power mechanism via the transmission rod to move the massage element. This completes the assembly of the massage device, improving assembly efficiency. When the relative position of the massage element needs adjustment, the second drive assembly rotates the transmission cylinder, causing the adjustment shell to move relative to the first shell body, resulting in a change in the connector. This, in turn, changes the position and massage range of the massage element. The power mechanism, via the first drive assembly, adjusts the massage intensity applied to the massaged area to meet the user's needs. Thus, this connecting device enables both motion control of the massage element and adjustment of its relative position, enhancing the user experience of the massage device.

[0026] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0039] To better understand the connection device of this disclosure, it will be described using a massage device in which the connection device is applied.

[0040] like Figure 1 As shown, in some embodiments, a massage device 1 is provided, including a support device 10, a power mechanism 20, a massage component 30, and a connecting device 40.

[0041] Among them, such as Figures 2 to 4As shown, the connecting device 40 includes a mounting shell 100 fixed to the supporting device 10, an adjusting assembly 200, a connecting member 300, a first driving assembly 400, and a second driving assembly 500 for driving the transmission cylinder 220 to rotate. The mounting shell 100 includes a first shell body 110 and a guide rail 120 fixed to the first shell body 110. The adjusting assembly 200 includes an adjusting shell 210 and a transmission cylinder 220. The adjusting shell 210 includes a guide portion 211 that guides and cooperates with the guide rail 120. The adjusting shell 210 is rotatably connected to the transmission cylinder 220, and the transmission cylinder 220 is provided with a through cavity 221. The connecting member 300 is movably connected to the adjusting shell 210 and is provided with a connecting portion 310 that connects to the massage member 30. The first driving assembly 400 includes a driving member 410 rotatably disposed between the connecting member 300 and the transmission cylinder 220 and a transmission rod 420 rotatably disposed on the mounting shell 100. The driving component 410 is in a transmission engagement with the connecting component 300 to drive the connecting component 300 to move. One end of the transmission rod 420 passes through the through cavity 221 and is transmissionally connected to the driving component 410 to drive the driving component 410 to rotate. When the transmission cylinder 220 rotates relative to the mounting shell 100, it can drive the adjusting shell 210 to move relative to the first shell body 110. The power mechanism 20 is located on the bearing device 10 and is transmissionally connected to the transmission rod 420.

[0042] During assembly, the connector 300 and drive assembly are integrated into the adjustment assembly 200, allowing the connector 300 to rotate relative to the adjustment shell 210 and be connected to the transmission rod 420 via the drive assembly 410. At this time, the mounting shell 100 is fixed to the support assembly, connected to the massage element 30 via the connector 310, and connected to the power mechanism 20 via the transmission rod 420 to drive the massage element 30 to move. This completes the assembly of the massage device 1. Thus, the connector 40 can be modularly assembled onto the support assembly 10, improving the assembly efficiency of the massage device 1. When massage is needed, the power mechanism 20 generates power, which drives the drive assembly 410 to rotate via the transmission rod 420, and the drive assembly 410 drives the massage element 30 mounted on the connector 300 to move. When the relative position of the massage element 30 needs to be adjusted, the second drive assembly 500 drives the transmission cylinder 220 to rotate, driving the adjustment shell 210 to move relative to the first shell body 110, causing the connector 310 to change accordingly. This causes a change in the position of the massage element 30, and also changes the massage range of the massage element 30. The power mechanism 20, through the first drive assembly 400, drives the massage element 30 to adjust the massage intensity applied to the massaged area, thereby meeting the user's massage needs. In this way, the connecting device 40 can both control the movement of the massage element 30 and adjust its relative position, which helps to improve the user experience of the massage device 1.

[0043] Understandably, the massage component 30 is independently assembled on the connecting device 40 via the connecting part 310, and will not interfere with the power mechanism 20 or other moving components on the bearing device 10. This also makes the massage device 1 less need to have a large amount of clearance space, resulting in a compact structure and facilitating the miniaturization of the massage device 1.

[0044] Furthermore, it is understandable that since the adjusting shell 210 is slidably connected to the first shell body 110, the adjusting shell 210 will not move during the process of the transmission rod 420 driving the transmission cylinder 220 to rotate and driving the connecting member 300 to rotate. This allows the connecting member 300 to move relative to the adjusting shell 210, thereby controlling the movement trajectory of the connecting part 310 through the adjusting shell 210. The adjusting shell 210 can move relative to the first shell body 110, and can also adjust the position of the connecting member 300 relative to the first shell body 110.

[0045] It should be noted that there are various ways to achieve the sliding connection between the adjusting shell 210 and the first shell body 110, including but not limited to slide rails and slide grooves, guide rails and guide blocks, etc.

[0046] like Figure 3 As shown, in some embodiments, the mounting housing 100 includes a guide rail 120 fixed to the first housing body 110. The adjusting housing 210 includes a guide portion 211 that guides and cooperates with the guide rail 120. Thus, through the guide portion 211 and the guide rail 120, a sliding connection between the adjusting housing 210 and the first housing body 110 is easily achieved. Furthermore, through the guide portion 211 and the guide rail 120, the adjusting housing 210 remains stationary while the transmission rod 420 drives the driving member 410 to rotate the connecting member 300. This allows the connecting member 300 to move relative to the adjusting housing 210, thereby enabling the movement trajectory of the connecting member 310 to be controlled via the adjusting housing 210. The adjusting housing 210 can move relative to the first housing body 110, and can also adjust the position of the connecting member 300 relative to the first housing body 110.

[0047] like Figures 3 to 5 As shown, in some embodiments, the guide rail 120 is provided with a guide groove 121, and at least a portion of the guide portion 211 protrudes from the adjusting shell 210 and is inserted into the guide groove 121. In this way, by setting the guide portion 211 on the adjusting shell 210, it is easy to insert into the guide groove 121, thereby achieving a guiding engagement between the adjusting shell 210 and the first shell body 110.

[0048] like Figure 4As shown, in some embodiments, the transmission cylinder 220 includes a cylinder body 222 and a first rotating ring 223 fixed to the outer periphery of the cylinder body 222. The first rotating ring 223 is rotatably connected to the adjusting shell 210. The first rotating ring 223 is inclined, and the inclination direction of the first rotating ring 223 intersects the rotation axis of the transmission rod 420. Thus, during the process of the second drive assembly 500 driving the first rotating ring 223 to rotate via the cylinder body 222, since the first rotating ring 223 is inclined towards the first shell body 110, the lowest point position of the first rotating ring 223 relative to the first shell body 110 also changes. That is, the distance of the first rotating ring 223 located below the guide portion 211 of the adjusting shell 210 relative to the first shell body 110 also changes, thereby enabling the first rotating ring 223 to push the guide portion 211 to move relative to the guide rail 120, realizing the swinging of the adjusting shell 210 along the guide rail 120. As the position of the guide portion 211 of the adjustment housing 210 relative to the guide rail 120 changes, the position of the adjustment housing 210 also changes, which in turn causes the position of the massage member 30 installed on the adjustment housing 210 via the connecting portion 310 to also change.

[0049] Specifically, such as Figure 4 As shown, when the guide portion 211 needs to move away from the first shell body 110, the first rotating ring 223 rotates along the first rotation direction, and the first rotating ring 223 is used to push the guide portion 211 to move away from the first shell body 110. The first shell body 110 swings clockwise, and the guide portion 211 is supported by the part of the first rotating ring 223 that is further away from the first shell body 110.

[0050] Similarly, when the guide portion 211 needs to move toward the direction closer to the first shell body 110, the first rotating ring 223 rotates in the opposite direction of the first rotation direction, and the first rotating ring 223 is used to push the guide portion 211 toward the direction closer to the first shell body 110. The first shell body 110 swings counterclockwise, and the part of the first rotating ring 223 that is closer to the first shell body 110 is used to support the guide portion 211.

[0051] like Figure 4As shown, in some embodiments, the adjusting shell 210 is provided with a limiting cavity 201, which includes a limiting notch 2011 and a transmission notch 2012 opposite to the limiting notch 2011. The connecting member 300 includes a rotating part 320 fixedly connected to the connecting part 310. The rotating part 320 is rotatably disposed within the limiting cavity 201 and is anti-detached from the limiting notch 2011. The connecting part 310 is exposed outside the limiting notch 2011. The driving member 410 is rotatably disposed within the limiting cavity 201 and is in a transmission engagement with the rotating part. The first rotating ring 223 is rotatably disposed within the limiting cavity 201 and carries the driving member 410. Thus, the first rotating ring 223 and the driving member 410 are rotatably disposed within the limiting cavity 201 for protection. At the same time, the limiting cavity 201 can limit the rotation range of the connecting member 300, making it easier to plan the rotation range of the massage member 30. The connecting part 310 is exposed outside the limiting notch 2011, making it easy to assemble with the massage component 30. The setting of the transmission notch 2012 also facilitates the cylinder body 222 to pass through the transmission notch 2012 and be set outside the limiting cavity 201, so as to facilitate the second drive assembly 500 to drive the cylinder body 222 to rotate.

[0052] Understandably, the drive component 410 needs to be rotatably connected to the adjustment housing 210, and the connector 300 and the first rotating ring 223 also need to rotate. The setting of the limiting cavity 201 also facilitates the storage of lubricant in the limiting cavity 201, reducing the amount of rotational wear between the drive component 410, the connector 300, and the first rotating ring 223 and the adjustment housing 210, improving durability, reducing maintenance frequency, and thus increasing the service life of the massage device 1.

[0053] It should be noted that "the connecting part 310 is exposed in the limiting notch 2011" should be interpreted broadly. This includes at least a portion of the connecting part 310 protruding from the limiting notch 2011, and also includes the fact that the connecting part 310 is visible through the limiting notch 2011, i.e., exposed in the projection area of ​​the limiting notch 2011. The connecting part 310 can be connected to the massage component 30 through the limiting notch 2011.

[0054] It should be noted that the phrase "the rotating part 320 and the limiting notch 2011 are in a preventive engagement" should be interpreted broadly, meaning that the rotating part 320 will not detach from the limiting notch 2011 and separate from the limiting cavity 201. (Refer to...) Figure 4 It is understood that the rotating part 320 is ball-shaped, and its large end will get stuck at the limiting notch 2011 and cannot be separated from the limiting notch 2011.

[0055] like Figures 3 to 5As shown, in some embodiments, the adjusting shell 210 includes a second shell body 212 with a limiting cavity 201 and a cover plate 213 with a transmission notch 2012. The second shell body 212 is fixedly connected to the cover plate 213. The second shell body 212 has a limiting notch 2011. The guide portion 211 is fixed to the second shell body 212. The cover plate 213 carries the first rotating ring 223 so that the first rotating ring 223 is anti-detached from the transmission notch 2012. In this way, by the cooperation of the second shell body 212 and the cover plate 213, the rotating part 320, the driving member 410 and the first rotating ring 223 are easily rotatably encapsulated in the limiting cavity 201. Specifically, when assembling the connecting device 40, the rotating part 320 is inserted into the limiting cavity 201, and the rotating part 320 is anti-detached from the limiting notch 2011, while the connecting part 310 is exposed outside the limiting notch 2011, which facilitates assembly with the massage member 30 and restricts the movement trajectory of the massage member 30. Then, the driving component 410 is placed in the limiting cavity 201 and engages with the rotating part 320. Next, the first rotating ring 223 is inserted into the limiting cavity 201 to support the limiting driving component 410. Finally, the cover plate 213 is passed through the cylindrical body 222 and fixedly connected to the second shell body 212, so that the cover plate 213 can support and limit the first rotating ring 223, and prevent the first rotating ring 223 from detaching from the transmission notch 2012. The transmission rod 420 passes through the through cavity 221 and is connected to the driving component 410, facilitating the transmission connection of the driving mechanism. Alternatively, the driving component 410 can be assembled first, followed by the transmission rod 420, and then the first rotating ring 223 can be assembled.

[0056] Optionally, such as Figure 4 as well as Figure 5 As shown, the guide part 211 is integrally formed with the second shell body 212.

[0057] Optionally, in some embodiments, the second shell body 212 is provided with an annular groove 2013 communicating with the limiting cavity 201. The first rotating ring 223 is rotatably disposed in the annular groove 2013 and is anti-detached from the cover plate 213. In this way, by utilizing the engagement between the annular groove 2013 and the cover plate 213, the first rotating ring 223 can be reliably rotatably connected to the adjusting shell 210.

[0058] Optionally, such as Figure 4 as well as Figure 5 As shown, in some embodiments, the drive member 410 is provided with a second rotating ring 413 rotatably disposed in the annular groove 2013. In this way, the drive member 410 can also be reliably rotatably connected to the adjusting shell 210 through the second rotating ring 413.

[0059] like Figure 6As shown, in some embodiments, the sidewall of the annular groove 2013 is provided with an oil storage groove 2014. Thus, the oil storage groove 2014 reduces the frictional area between the first rotating ring 223 and the second rotating ring 413 and the adjusting shell 210, thereby reducing friction. Simultaneously, by storing lubricant in the oil storage groove 2014, the rotational friction of the first rotating ring 223 and the second rotating ring 413 can be reduced, thereby reducing kinematic wear and improving durability.

[0060] like Figure 4 as well as Figure 5 As shown, in some embodiments, the connecting portion 310 includes a connecting protrusion 311 fixedly connected to the rotating portion 320. At least a portion of the connecting protrusion 311 is disposed outside the limiting cavity 201 via a limiting notch 2011. The length direction of the connecting protrusion 311 is not coaxial with the rotation axis of the transmission rod 420. Thus, the connecting protrusion 311 facilitates connection with the massage member 30, and the connecting protrusion 311 drives the massage member 30 to rotate around the center of the ball.

[0061] Optionally, the connecting protrusion 311 and the rotating part 320 are integrally formed.

[0062] It should be noted that the connection methods between the connecting protrusion 311 and the massage component 30 include, but are not limited to, at least one of the following: plug-in fixing, detachable fixing, screw fixing, adhesive fixing, etc.

[0063] Furthermore, such as Figure 4 as well as Figure 5 As shown, in some embodiments, the rotating part 320 is limited by the spherical convex surface and the inner spherical surface of the adjusting shell 210, so that the rotating part 320 can rotate in all directions, making it easy to plan the rotation trajectory of the rotating part 320, so that the connecting part 310 can drive the massage member 30 to perform massage movement along the set trajectory.

[0064] Optionally, the connecting part 310 can drive the massage member 30 to reciprocate, reciprocate along a two-dimensional closed curve (e.g., along a circular curve or an elliptical curve), or reciprocate along a three-dimensional closed curve (e.g., an elliptical trajectory curved around a spherical convex surface).

[0065] like Figure 4 as well as Figure 5As shown, in some embodiments, the connecting device 40 further includes an angle detection component 600. The angle detection component 600 includes a trigger 610 fixed to the cylindrical body 222 and an angle detection module 620 fixed to the first shell body. The trigger 610 can trigger the angle detection module 620 to generate an angle detection signal. Thus, when the second driving component 500 drives the cylindrical body 222 to rotate, it can drive the trigger 610 to rotate, which facilitates the trigger 610 to trigger the angle detection module 620 to generate an angle detection signal and send it to the controller of the control device. This angle information is used to obtain the position information of the adjusting shell 210, and then the position information of the massage component 30 can be obtained, making it convenient to record the position of the massage component 30 for the next adjustment.

[0066] For example, the massage element 30 can be adjusted to multiple angles. The angle detection component 600 records the current angle of the massage element 30 for future adjustments. Specifically, the current position of the massage element 30 is the first-level position by default. When the user needs to adjust it to the second-level position, since the information that the massage element 30 is in the first-level position has been recorded, the controller can control the second drive component 500 to drive the cylinder body 222 to rotate the corresponding number of revolutions based on the recorded information and the rotation angle required to adjust to the second-level position, thereby adjusting the massage element 30 to the second-level position.

[0067] In some embodiments, the cylinder body is provided with an external thread structure (not shown), and the sidewall of the limiting cavity is provided with an internal thread structure (not shown) that engages with the external thread structure for helical transmission. Thus, through the principle of the screw and nut mechanism, the cylinder body drives the adjusting shell with the internal thread structure to helically drive through the external thread structure, enabling the adjusting shell to extend and retract along the length of the guide rail.

[0068] like Figure 4 As shown, in some embodiments, the drive member 410 is provided with a non-circular transmission hole 411 communicating with the cavity 221, and one end of the transmission rod 420 is engaged with the transmission hole 411. In this way, the internal space of the drive member 410 can be used to accommodate the transmission rod 420, so that the two fit tightly.

[0069] Optionally, such as Figure 4 As shown, in some embodiments, the transmission rod 420 is non-cylindrical and fits into the transmission hole 411. This facilitates assembly and enables a sliding connection between the transmission rod 420 and the drive component 410, but the two cannot rotate relative to each other.

[0070] Non-cylinders include polygonal regular prisms, elliptical cylinders, semi-cylinders, etc.

[0071] Optionally, in some embodiments, the end of the transmission rod 420 is provided with an anti-rotation protrusion 421, and the side wall of the transmission hole 411 is provided with an anti-rotation groove 412 that slides with the anti-rotation protrusion 421. Thus, the sliding connection between the transmission rod 420 and the driving member 410 is achieved by the engagement of the anti-rotation protrusion 421 and the anti-rotation groove 412, facilitating their assembly and disassembly. However, once connected, the anti-rotation protrusion 421 and the anti-rotation groove 412 prevent relative rotation between the driving member 410 and the transmission rod 420, facilitating the transmission of rotational power from the transmission rod 420 to the driving member 410, which then drives the connecting member 300 to move.

[0072] It should be noted that the second drive component 500 can be implemented in various ways, including but not limited to devices that directly provide rotational power such as servo motors and rotary hydraulic cylinders, as well as other devices that indirectly provide rotational power, such as pneumatic rods / hydraulic cylinders / linear motors + rack and pinion mechanisms, pneumatic rods / hydraulic cylinders / linear motors + crank-rocker mechanisms or crank-slider mechanisms, servo motors + gearboxes, servo motors + flexible transmission mechanisms, etc. All of these can be implemented in conventional technologies and will not be elaborated upon here.

[0073] See you later Figure 2 As shown, in some embodiments, the second drive assembly 500 includes a rotary power source 510, an active member 520 that is driven to the rotating end of the rotary power source 510, and a driven member 530 that is driven to the transmission cylinder 220 on the same axis. The active member 520 can drive the driven member 530 to rotate.

[0074] It should be noted that there are various ways to implement the "driving element driving the driven element to rotate". For example, the driving element can drive the driven element to rotate through a flexible transmission component (i.e., forming a flexible transmission component such as a belt drive assembly or a chain drive assembly). Another example is that in some embodiments, the driving element is a driving gear, and the driven element is a driven gear meshing with the driving gear. This can improve the transmission accuracy and reliability between the driving and driven elements, which is beneficial for improving the accuracy of the massage element's position adjustment.

[0075] For example, such as Figure 2 As shown, in some embodiments, the driving member 520 includes a worm gear, and the driven member 530 includes a turbine. Thus, the rotary power source 510 drives the transmission cylinder 220 to rotate via the worm gear and turbine, resulting in a compact transmission structure that facilitates miniaturization of the connecting device 40.

[0076] The rotary power source 510 includes an electric motor.

[0077] In the description of this disclosure, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0078] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0079] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0080] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0081] It should be noted that when a component is described as "fixed to," "set on," "fixed to," or "mounted on" another component, it can be directly on the other component or there may be an intervening component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component. Furthermore, when a component is considered to be "transmittingly connected" to another component, the two can be fixed in a detachable or non-detachable manner, as long as power transmission can be achieved. For example, sleeve transmission fits, snap-fit ​​transmission fits, pin fixings, non-cylindrical transmission fits, integral molding fixings, welding, etc., can be achieved in traditional technologies and will not be elaborated here.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
