[0036] Please also read Figures 1 to 6 , the transmission device and massager provided in the embodiments of the present application are now described.

[0037] Generally speaking, a massager includes elastic massage parts that are in contact with human skin. The massage parts are driven by a transmission device in the massager to achieve various massage actions such as vibration, hammering, kneading, pinching, clamping, and patting. The massager includes a transmission device and a sleeve. The transmission device is used to drive the sleeve to move, so that the sleeve can perform various massage actions such as vibration, hammering, kneading, pinching, clamping, and patting on different parts of the user's body.

[0038] In addition, it should be noted that the first direction, the second direction and the third direction described in the following embodiments are three directions perpendicular to each other.

[0039] It can be understood that the transmission device of the present application is used in a massager.

[0040] refer to Figures 1 to 6 The transmission device and massager described in the first embodiment of the present application are used to realize the patting function.

[0041] The transmission device includes a frame 100, a rotating motor 200, a shaking member 300 and a shaking driving assembly 400. The specific arrangement of each component is as follows.

[0042] The rotary motor 200 is disposed on the frame 100 along the first direction, that is, the rotating shaft 210 of the rotary motor 200 is disposed parallel to the first direction.

[0043] The rocking member 300 is swingably arranged on the frame 100 around the second direction, and more specifically, the rocking member 300 is swingably arranged above the rotating motor 200. It includes a rocking part 310 and a driven part 320. It can be understood that the respective extension directions of the rocking part 310 and the driven part 320 are perpendicular or nearly perpendicular to each other. For example, in the initial position state, the extension direction of the driven part 320 is parallel to the first direction, and the extension direction of the rocking part 310 is parallel to the third direction; at the same time, the rocking part 310 can be set to a wave shape, a curved shape or other special shapes to provide a better slapping feeling when slapping the user's body parts; in addition, the driven part 320 needs to be made of hard material, such as hard plastic, so that when it is driven by the swing driving member and drives the rocking part 310 to swing, its own elastic deformation is small to obtain a higher driving efficiency, and the material of the rocking part 310 can be selected from hard materials or materials with a certain flexibility, such as hard plastic or silicone materials with a certain hardness and a certain flexibility.

[0044] The rocking drive assembly 400 is movably disposed on the frame 100 and is located on the same side of the rotating motor 200 and the rocking member 300 . The rocking drive assembly 400 can rotate, swing or move linearly on the frame 100 , but is not limited thereto.

[0045] The shaking drive assembly 400 includes a first component and a second component that are movably connected to each other, wherein the first component is connected to the rotating shaft 210, and one end of the second component away from the first component is connected to the driven part 320, and one end of the second component away from the first component can move linearly along the third direction to drive the shaking member 300 to shake. When the rotating shaft 210 rotates, the first component can drive one end of the second component away from the first component to move linearly along the third direction, so that the second component pulls the driven part 320 to shake around the third direction, and finally the shaking part 310 can shake.

[0046] By setting the axial direction of the rotating motor 200 along the first direction, and making the rocking member 300 rock around the second direction, and at the same time setting the swinging drive direction of the rocking member 300 by the rocking drive assembly 400 to the third direction, in this way, the space in three mutually perpendicular directions on the massager can be effectively utilized to reduce the length of the transmission device, thereby realizing the miniaturization of the massager.

[0047] refer to Figure 5In some embodiments, a first through hole 421 is formed through the second component, and a ball socket 422 connected to the first through hole 421 is provided on one side surface of the second component. It is understandable that when the second component is driven to move by the first component, the first through hole 421 and / or the ball socket 422 reciprocate in the third direction. At the same time, the driven part 320 includes a rod 321 and a ball head 322, the rod 321 passes through the first through hole 421 and the ball head 322 is accommodated in the ball socket 422. In this way, when the second component is driven by the first component, the driven part 320 can smoothly shake around the second direction.

[0048] It can be understood that the first component and the second component can have the following several implementations.

[0049] In some embodiments, the first component and the second component are two rotatably connected rods, and the length of the first component is smaller than that of the second component. One end of the first component is fixedly connected to the rotating shaft 210, and the other end is rotatably connected to the second component.

[0050] In other embodiments, the first component is a disc-shaped component, the second component is a rod, and the second component is rotatably connected to the eccentric portion of the first component. For example, the first component may be a cam disc, and the second component is rotatably connected to the end surface of the cam disc; or it may be a disc, and a connecting column is provided at the eccentric portion of the end surface of the disc, and the second component is rotatably connected to the connecting column.

[0051] refer to Figures 1 to 6 In some other embodiments, the first component is a circular eccentric rotating disk 410, and the second component is a swing rod 420. The swing rod 420 is long and narrow, and a second through hole 423 is provided at one end of the swing rod 420 away from the first through hole 421. The eccentric rotating disk 410 is rotatably disposed in the second through hole 423, and the eccentric rotating disk 410 is fixedly connected to the rotating shaft 210 at an axial position deviating from the second through hole 423. In this way, when the rotating shaft 210 rotates, the eccentric rotating disk 410 follows the rotation of the rotating shaft 210 and rotates eccentrically. When the eccentric rotating disk 410 rotates, it can drive the swing rod 420 to swing periodically, so that the first through hole 421 on the swing rod 420 can move linearly along the third direction under the restriction of the driven part 320, so that the driven part 320 swings around the second direction.

[0052] Furthermore, in some embodiments, a bearing 430 is rotatably provided between the hole wall of the second through hole 423 and the eccentric rotating disk 410. By providing the bearing 430, the rotation between the first component and the second component 420 can be made smoother, so as to reduce the noise when the shaking driving assembly 400 moves, thereby improving the massage experience of the massager.

[0053] On the basis of any of the above embodiments, the specific configurations of the rotating motor 200, the shaking driving assembly 400 and the shaking member 300 are as follows. Specifically, a receiving chamber 110 is provided in the frame 100 along the first direction, and the rotating motor 200 is provided in the receiving chamber 110; the shaking driving assembly 400 is movably provided at one side of the receiving chamber 110; and the shaking member 300 is swingably provided above the receiving chamber 110. By such configuration, the space utilization rate of each part on the frame 100 is high, and the volume of the transmission device can be effectively reduced, so as to facilitate the miniaturization of the volume of the massage device.

[0054] Furthermore, two connecting parts 120 are arranged on the frame 100 above the accommodating cavity 110, and the two connecting parts 120 are symmetrically arranged along a plane parallel to the first direction and the third direction; the rocking member 300 includes a rocking shaft 330, and both ends of the rocking shaft 330 are rotatably arranged on the two connecting parts 120. In this way, when the rocking member 300 is driven by the second component, the movement is more stable, that is, the rocking part 310 has better stability when swinging and beating, so as to improve the massage experience.

[0055] It can be understood that, based on any of the above embodiments, the rotating motor 200 can be a single-output shaft motor or a dual-output shaft motor.

[0056] When the rotating motor 200 is a dual-output shaft motor, one end of the rotating shaft 210 is connected to the shaking drive assembly 400, and the other end of the rotating shaft 210 is connected to the eccentric drive disk 510. Similarly, a connecting column 511 is provided on the eccentric drive disk 510, and a movable member 520 is rotatably connected to the connecting column 511. The movable member 520 can be a rod. In some embodiments, the length extension direction of the rod is roughly parallel to the third direction. When the eccentric drive disk 510 rotates, the movable member 520 can reciprocate along a direction roughly parallel to the third direction.

[0057] When the rotating shaft 210 rotates, the rotating shaft 210 synchronously drives the shaking driving assembly 400 and the eccentric driving disk 510 to move, so that the shaking member 300 located above the rotating motor 200 and the movable member 520 located on one side of the rotating motor 200 can move simultaneously to achieve a variety of different massage actions at the same time.

[0058] In a second embodiment of the present application, a massager is provided, which includes a housing, an elastic sleeve, and a transmission device of any of the above embodiments, wherein the transmission device is disposed inside the housing; wherein the elastic sleeve is sleeved outside the transmission device. During massage, the elastic sleeve contacts a user's body part.

[0059] More specifically, when only the rocking member 300 is provided in the transmission device, the elastic sleeve is wrapped around the outer side of the rocking part 310; and when both the rocking member 300 and the movable member 520 are provided in the transmission device, the elastic sleeve is wrapped around the outer side of both the rocking part 310 and the movable member 520.

[0060] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
