[0027] To make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following describes this application in further detail with reference to the accompanying drawings and embodiments.

Therefore, they should not be construed as limitations on this application.

[0032] Furthermore, the terms "first" and "second" 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" or "second" may explicitly or implicitly include one or more of that feature.

[0033] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0034] Please refer to the following: Figures 1 to 6 The transmission device and massager provided in the embodiments of this application will now be described.

[0035] Generally speaking, a massager includes elastic massage components that come into contact with the skin. These components are driven by a transmission device within the massager to perform various massage actions such as vibration, hammering, kneading, pinching, and clamping.

[0036] It is understood that, on the one hand, the transmission device of this application is used in a massager, and the transmission device includes a linear movement component 300 and at least one clamping plate 420; on the other hand, in this application, the massager is provided with at least two elastic elements that come into contact with the skin, and each elastic element is respectively provided on the outside of the linear movement component 300 and the clamping plate 420, so as to massage the skin by following the movement of the linear movement component 300 or the clamping plate 420.

[0037] Understandably, reference Figures 1 to 3 The transmission device provided in the first aspect of this application includes a frame 100, the aforementioned linear movement component 300, and a swing component 400.

[0038] Specifically, a motor 200 is mounted on the frame 100. A linear motion component 300 is slidably mounted on the frame 100 parallel to its axis and is connected to the output shaft of the motor 200 via a transmission component 500. When the motor 200 rotates, it drives the linear motion component 300 to perform linear reciprocating motion along the axial direction of the frame 100. That is, the transmission component 500 is used to convert the rotation of the motor 200 into the linear reciprocating motion of the linear motion component 300. For example, in some embodiments, the transmission component 500 may consist of a cam / eccentric wheel and a crank mechanism.

[0039] The swing assembly 400 includes a drive member 410 and at least one clamping piece 420. The drive member 410 is slidably disposed on the frame 100 along its axial direction. The drive member 410 is also connected to the output shaft of the motor 200 via a transmission assembly 500. When the motor 200 rotates, it drives the drive member 410 to perform linear reciprocating motion along the axial direction of the frame 100. In other words, the transmission assembly 500 converts the rotation of the motor 200 into the linear reciprocating motion of the drive member 410. For example, in some embodiments, the transmission assembly 500 may also consist of a cam / eccentric wheel and a crank mechanism. The clamp 420 is oscillatingly disposed on the frame 100 and movably connected to the drive member 410. The clamp 420 is disposed on the periphery of the linear motion assembly 300. Thus, when the drive member 410 reciprocates along a straight line, the clamp 420 can oscillate back and forth under the drive of the drive member 410 to move closer to or away from the linear motion assembly 300. In different embodiments, the drive member 410 and the clamp 420 can be movably connected by a pull rod. When the drive member 410 moves, it drives the pull rod, causing the pull rod to pull the clamp 420 to oscillate.

[0040] By configuring the transmission device in this way, the swinging motion of the clamp 420 and the linear motion of the linear movement component 300 can both be driven by a single motor 200. This reduces the structural volume and energy consumption of the transmission device while simultaneously achieving multiple massage states, making the massager more portable and providing a longer battery life.

[0041] refer to Figures 1 to 4 In some embodiments, the output shaft of the motor 200 is arranged parallel to the axis of the frame 100. Since the length of the motor 200 in its axial direction is greater than its diameter, by arranging the mounting position of the motor 200 in this way, the size of the massager in the width direction can be reduced, making it easier for the user to hold and improving the comfort of use.

[0042] Furthermore, the drive ends of the linear motion component 300 and the drive component 410, which are connected to the transmission component 500, are located on both sides of the axis of the motor 200. This allows for the rational use of the space on both sides of the width of the transmission device and makes the mass distribution on both sides of the axis of the frame 100 more uniform.

[0043] In some embodiments, the transmission assembly 500 may have multiple implementations.

[0044] For example, it could be a first bevel gear connected to the output shaft of the motor 200, a second bevel gear meshing with the first bevel gear, a cam driven by the second bevel gear, and a crank mechanism driven by the cam, which directly drives the drive component 410 and the linear motion component 300 to reciprocate in a straight line.

[0045] For example, it could also be a worm gear 510 connected to the output shaft of the motor 200, a worm wheel 521 meshing with the worm gear 510, a gear set 520 connected to the worm wheel 521, and a cam and crank mechanism driven by the gear set 520. Similarly, the crank mechanism directly drives the drive member 410 and the linear motion assembly 300 to reciprocate in a straight line. With this configuration, the transmission assembly 500 requires less space and can make full use of the limited space inside the massager.

[0046] It should be understood that the specific configuration of the transmission component 500 is not limited to this.

[0047] refer to Figure 4 Based on the aforementioned transmission assembly 500 consisting of a worm gear 510 and a gear set 520, the transmission assembly 500 can have the following refined implementation. Specifically, both the driving end of the linear motion assembly 300 and the driving end of the driving member 410 are provided with grooves whose length direction is perpendicular to the axis of the frame 100, namely a first groove 310 and a second groove 413, located on opposite sides of the axis of the frame 100. Simultaneously, a swing column 530 is eccentrically mounted on the gear of the gear set 520, and an eccentric swing rod 540 is connected to the worm gear 521; both the swing column 530 and the eccentric swing rod 540 slide in cooperation with the grooves.

[0048] Specifically, the gear set 520 includes two-stage transmission gears, namely a second gear 522 and a third gear 523. The second gear 522 is coaxially fixed with the worm gear 521, and the third gear 523 meshes with the second gear 522 for transmission. An eccentric rocker arm 540 is fixedly connected to the end of the worm gear 521 away from the second gear 522. The eccentric rocker arm 540 is slidably engaged with the first slide groove 310 to pull the linear motion component 300 to reciprocate in a straight line. A rocker column 530 is formed at an eccentric position on the end face of the third gear 523. The rocker column 530 is slidably engaged with the second slide groove 413 to pull the drive component 410 to reciprocate in a straight line.

[0049] Preferably, rolling elements 550 are provided on the eccentric rocker arm 540 and the rocker column 530. The rolling elements 550 can be bearings. Each rolling element 550 rolls into the first slide groove 310 and the second slide groove 413 respectively, so as to reduce the friction when the transmission assembly 500 pulls the drive assembly 410 and the linear motion assembly 300, thereby achieving low noise and smoother drive. Furthermore, both the first slide groove 310 and the second slide groove 413 are provided with limiting end faces, which are used to prevent the rolling elements 550 from disengaging from the first slide groove 310 or the second slide groove 413.

[0050] refer to Figures 1 to 3 and Figure 5In some embodiments, the clip 420 is provided with three pieces, and each clip 420 is located at a different peripheral position of the linear motion component 300. In this way, when the user uses the device, the clips 420 at different positions can provide the user with different massage sensations, thereby enhancing the massage experience.

[0051] In some specific embodiments, two clamping plates 420 are arranged symmetrically about the center of the drive member 410, and another clamping plate 420 is disposed between the two symmetrically arranged clamping plates 420. Thus, when the drive member 410 moves linearly, the two symmetrically arranged clamping plates 420 can swing synchronously to move closer or further apart from each other, while the movement timing of the other clamping plate 420 is not limited; it can swing synchronously with the aforementioned two clamping plates 420 or its swing timing can be staggered, thereby providing the user with a rich massage experience.

[0052] refer to Figure 6 Based on any of the above embodiments, a sliding hole 110 is provided in the frame 100, and the linear motion component 300 is slidably sleeved in the sliding hole 110 of the frame 100; at the same time, a surrounding wall 120 is provided on the frame 100 around the sliding hole 110, and the driving component 410 is slidably sleeved on the outside of the surrounding wall 120. In this way, the linear motion component 300 and the driving component 410 are sleeved on each other, making the transmission device structure more compact, so as to further improve the utilization rate of the internal space of the massager.

[0053] refer to Figure 5 Furthermore, the connection between the drive component 410 and the clamp 420 can be implemented in the following ways.

[0054] Specifically, an arc-shaped groove 4111 is provided on the peripheral sidewall of the drive component 410. The number of arc-shaped grooves 4111 should be greater than or equal to the number of clamping pieces 420, and each arc-shaped groove 4111 is located at a different circumferential position.

[0055] The clamping piece 420 includes a body 421 and a connecting portion 422. The connecting portion 422 extends circumferentially along the drive member 410 and is arc-shaped. One end of the connecting portion 422 near the body 421 is fixedly connected to the body 421, and the other end of the connecting portion 422 away from the body 421 is provided with a plug 423 for insertion into the arc-shaped groove 4111. When the drive member 410 moves reciprocally in a straight line, the position of the plug 423 in the arc-shaped groove 4111 changes constantly, thereby pulling or pushing the body 421 to rotate, so as to realize the swinging motion of the clamping piece.

[0056] Furthermore, for the two centrally symmetrically arranged clamping plates 420, their corresponding arc-shaped grooves 4111 are also centrally symmetrically arranged on the peripheral wall of the driving member 410. For the other clamping plate 420, the size and arc direction of its arc-shaped groove 4111 can be the same as or different from the other arc-shaped grooves 4111. It should be understood that the extension direction of the arc-shaped groove 4111 affects the sequence of changes in the swing direction of the clamping plate 420 relative to the driving member 410, and the specific arrangement of the arc-shaped groove 4111 is not limited to this.

[0057] refer to Figures 1 to 3 and Figure 5 and Figure 6 Furthermore, in some embodiments, the driving member 410 includes a sleeve 411 slidably disposed on the frame 100 and a driving end that is drively connected to the transmission assembly 500. An arc-shaped groove 4111 is formed in the sleeve 411; a connecting member 412 is connected between the driving end and the sleeve 411, and a gap is spaced between the connecting member 412 and a portion of the peripheral wall of the sleeve 411, with the connecting portion 422 passing through the gap. By providing the connecting member 412 between the sleeve 411 and the driving end of the driving member 410, the connecting member 412 bypasses a portion of the structure on the frame 100, so that the driving member 410 will not interfere with the frame 100 when moving vertically; at the same time, by having the connecting portion 422 pass through the gap between the connecting member 412 and the frame 100, the overall diameter of the swing assembly 400 can be reduced, making the structure of the transmission assembly 500 more compact and reasonable.

[0058] In a second aspect of this application, a massager is provided, comprising the transmission device of any of the foregoing embodiments, and at least two elastic elements, namely a first elastic element and a second elastic element. Specifically, the first elastic element is columnar and is sleeved on the outside of the linear motion assembly 300; the second elastic element is annular and is simultaneously sleeved on two centrally symmetrically arranged clamping pieces 420 and surrounding the first elastic element. The second elastic element may also simultaneously sleeve another clamping piece 420 therein. When the transmission device is activated, the first elastic element extends and retracts, while the second elastic element contracts and releases, thereby allowing the user to experience more different massage states.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
