Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0034] In the description of the present application, "a plurality of" means two or more, unless otherwise specifically defined.

[0035] Please refer to Figures 1 to 6 together, and now the transmission device and the massager provided by the embodiments of the present application will be described.

[0036] Generally speaking, a massager includes an elastic massage member that contacts a body part. The massage member is driven by a transmission device in the massager to achieve various massage actions such as shaking, hammering, kneading, pinching, clamping, and patting; the massager includes a transmission device and a sleeve body. The transmission device is used to drive the sleeve body to move, so that the sleeve body can perform various massage actions such as shaking, hammering, kneading, pinching, clamping, and patting on different body parts of the user.

[0037] It can be understood that the transmission device of the first aspect embodiment of the present application is used in the massager of the second aspect embodiment, and it is used to enable the massager to have the massage effects of patting and vibrating or hammering. Among them, the massager of the second aspect embodiment includes a housing and at least two elastic massage members provided on the housing. One elastic massage member is wrapped around the outside of the rocker arm assembly 300 in the transmission device in the following embodiment, and the other elastic massage member is wrapped around the outside of the functional assembly 400 in the transmission device in the following embodiment.

[0038] When the transmission device operates, the rocker arm assembly 300 and the functional assembly 400 drive each elastic covering member to move simultaneously, so that the elastic covering member can periodically pat or hammer or vibrate the body part of the consumer to achieve the massage effect.

[0039] In the description of the following embodiments, the first direction, the second direction, and the third direction are perpendicular to each other; the plane where the first direction and the second direction are located is defined as the first plane, and the plane where the first direction and the third direction are located is defined as the second plane.

[0040] Refer toFigures 1 to 6 The transmission device according to the embodiment of the first aspect of the present application includes a frame (not shown in the figure), a dual-output shaft motor 100, two swing plate assemblies 200, a rocker arm assembly 300, and a functional assembly 400.

[0041] Specifically, the dual-output shaft motor 100 is disposed on the frame, and the axial direction of the output shaft of the dual-output shaft motor 100 is defined as the first direction.

[0042] The two swing plate assemblies 200 are respectively connected to the output shafts at both ends of the dual-output shaft motor 100. When the dual-output shaft motor 100 rotates, it can synchronously drive the two swing plate assemblies 200 to swing reciprocally in a plane perpendicular to the axis of the output shaft motor (i.e., the first plane). More specifically, the swinging directions of the two swing plate assemblies 200 are the same, and both swing repeatedly within a range on one side of the dual-output shaft motor 100.

[0043] It can be understood that the swing plate assembly 200 can be a cam structure, a crank-link structure, an eccentric swing plate structure, etc., and is not specifically limited thereto.

[0044] Reference Figures 1 to 6 It can be understood that the two swing plate assemblies 200 are respectively a first swing plate assembly 200a and a second swing plate assembly 200b.

[0045] Among them, the rocker arm assembly 300 is disposed on the first swing plate assembly 200a. The rocker arm assembly 300 includes a rotating part 310 and a rocker arm 320 fixedly disposed on one side of the rotating part 310. The rotating part 310 is rotatably disposed on the frame and its rotation axis is perpendicular to the axis of the output shaft. The direction where the rotation axis of the rotating part 310 is located is defined as the second direction. Among them, the rotating part 310 is connected to the end of the first swing plate assembly 200a far from the output shaft, and the rocker arm 320 extends in a direction away from the dual-output shaft motor 100. When the first swing plate assembly 200a swings reciprocally, it can drive the rocker arm 320 to swing around the axis of the rotating part 310.

[0046] It can be understood that the rocker arm 320 can be integrally formed with the rotating part 310, or can be detachably disposed with the rotating part 310, and is not specifically limited thereto; at the same time, the rocker arm 320 can be made of a material with greater flexibility, or can be integrally formed with the rotating part 310 from the same material; in addition, the rocker arm 320 can be an arc-shaped long strip, or can be a special-shaped long strip, and the aforementioned special shape can be a wavy shape, etc.

[0047] It can be understood that since the rotating part 310 is rotatably arranged on the housing and connected to the first swing plate assembly 200a, both ends of the first swing plate assembly 200a are respectively connected to the output shaft and the rotating part 310. That is to say, both ends of the first swing plate assembly 200a are subject to movement constraints, so that when the output shaft rotates, it can drive the first swing plate assembly 200a to swing reciprocally in the first plane, so as to drive the rotating part 310 to rotate, and finally realize the reciprocating swing movement of the rocker arm 320 in the second plane.

[0048] The functional component 400 is arranged or connected to the side of the second swing plate assembly 200b far from the output shaft.

[0049] Reference Figures 4 to 6 , specifically, when the functional component 400 is the hammer part 410, it is fixedly connected to the second swing plate assembly 200b or integrally formed therewith; in this setting mode, the elastic massage part in the massager is wrapped around the outside of the hammer part 410. That is to say, the hammer part 410 is kept connected to the housing of the massager, and both ends of the second swing plate assembly 200b are subject to movement constraints. When the output shaft rotates and drives the second swing plate assembly 200b to swing reciprocally in the first plane, the hammer part 410 can swing with the second swing plate assembly 200b to achieve the massage effect of periodic hammering.

[0050] Reference Figures 1 to 3 , when the functional component 400 is the vibration component 420, it is movably arranged on the frame and connected to the second swing plate assembly 200b, and the vibration component 420 can be a vibration motor. It can be understood that in this embodiment, both ends of the second swing plate assembly 200b are subject to movement constraints. When the output shaft rotates and drives the second swing plate assembly 200b to swing reciprocally in the first plane, the vibration component 420 can swing with the second swing plate assembly 200b to achieve the massage effect of periodically approaching or moving away from the body part (that is, different vibration intensities) while realizing the vibration effect.

[0051] By setting the transmission device in this way, when the dual-output shaft motor 100 rotates, it can drive the rocker arm 320 assembly and the functional component 400 to swing simultaneously, so as to realize the movement of two massage structures driven by a single drive source, and while having a variety of different massage experiences, it can save the space occupied by the drive source, which is beneficial to the miniaturization of the volume of the massager.

[0052] Reference Figure 3 and Figure 6, in some embodiments, the swing plate assembly 200 includes a connection plate 210, a bearing 220, and a swing plate 230; a first assembly hole 231 is formed at one end of the swing plate 230, the connection plate 210 is disposed in the first assembly hole 231, and the bearing 220 is connected between the connection plate 210 and the inner side wall of the first assembly hole 231. The connection plate 210 is fixedly connected to the output shaft at an eccentric position deviating from the axis of the bearing 220; the rocker arm assembly 300 or the functional assembly 400 is connected or formed at a position on the swing plate 230 far from the first assembly hole 231.

[0053] It should be understood that the foregoing rocker arm assembly 300 or functional assembly 400 is respectively connected to the swing plate 230. Thus, since both ends of the swing plate 230 are subject to movement constraints, when the output shaft rotates, the connection plate 210 can drive the swing plate 230 to swing eccentrically while rotating eccentrically, and the swing amplitude of the swing plate 230 in the direction away from the output shaft is the largest, so that the rocker arm assembly 300 or the functional assembly 400 can be better driven to swing within a larger range to improve the massage experience.

[0054] Reference Figure 3 and Figure 6 , in a further embodiment, a second assembly hole 232 is formed at one end of the swing plate 230 in the first swing plate assembly 200a far from the first assembly hole 231; a first swing post 311 is formed on the rotating part 310, and one end of the first swing post 311 is movably disposed in the second assembly hole 232; when the swing plate 230 swings back and forth, it pulls the rotating part 310 to swing to drive the rocker arm 320 to swing. Specifically, a rubber ring can be sleeved in the second assembly hole 232, and the first swing post 311 is inserted into the rubber ring to achieve universal rotation with low movement clearance in the second assembly hole 232.

[0055] Reference Figures 1 to 3 , on the basis of any of the foregoing embodiments, two rocker arms 320 are provided on the rotating part 310, and the two rocker arms 320 are oppositely disposed in a direction parallel to the first direction. Thus, when the first swing plate assembly 200a swings back and forth, it can drive the two rocker arms 320 to swing simultaneously to achieve a better massage effect.

[0056] Reference Figures 4 to 6 , in the embodiment where the functional assembly 400 is the hammering part 410, the foregoing hammering part 410 is formed at one end of the swing plate 230 in the second swing plate assembly 200b far from the first assembly hole 231. Specifically, the hammering part 410 includes a connecting arm 411 extending toward the side close to the rocker arm assembly 300 and a hammer head 412 disposed at the end of the connecting arm 411. It can be understood that the foregoing elastic massage member is coated on the outside of the hammer head 412.

[0057] Reference Figures 1 to 3, in the embodiment where the functional component 400 is the vibration component 420, the vibration component 420 includes a rotating seat 421 rotatably arranged on the frame body and a vibration device 422 arranged in the rotating seat 421. The rotating seat 421 is movably connected to the swing plate 230 in the second swing plate assembly 200b. Moreover, the axis of rotation of the rotating seat 421 is perpendicular to the axis of the output shaft, that is, the axis of rotation of the rotating seat 421 is parallel to the axis of rotation of the rotating part 310 (that is, parallel to the second direction). Thus, similar to the movement mode of the rotating part 310, when the second swing plate assembly 200b reciprocally swings on the first plane, it can drive the rotating seat 421 to reciprocally swing on the second plane.

[0058] Reference Figure 3 , in a further embodiment, a third assembly hole 233 is formed at one end of the swing plate 230 in the second swing assembly away from the first assembly hole 231, and a second swing post 4211 is arranged on the rotating seat 421; specifically, a rubber ring is sleeved in the third assembly hole 233, and one end of the second swing post 4211 is inserted into the rubber ring to achieve universal rotation in the third assembly hole 233. When the second swing plate assembly 200b reciprocally swings on the first plane, the swing plate 230 in the second swing plate assembly 200b can pull the second swing post 4211 to swing universally in the third assembly hole 233, so as to realize the reciprocal swing of the rotating seat 421 on the second plane.

[0059] In a further embodiment, an installation position is arranged on one side of the rotating seat 421 away from the dual-output shaft motor 100, and the installation position is used for detachably arranging the vibration device 422.

[0060] Reference Figures 1 to 6 , on the basis of the above embodiments, the rocker arm assembly 300 and the functional component 400 are respectively arranged on the sides of the first swing plate assembly 200a and the second swing plate assembly 200b that are away from each other.

[0061] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
