Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0023] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0024] Please refer to the following: Figures 1 to 7 The massager driving device provided in the embodiments of this application will now be described.

[0025] It is understood that the massager drive device described in this application embodiment is used to be assembled in a massager. A soft material (such as silicone) covering is provided on the outside of the drive device to directly contact the skin. The movement of the clamp arm 400 and the swing column 700 in the drive device drives the covering to move, thereby realizing the massage sensation.

[0026] Understandably, reference Figures 1 to 7 The massager driving device provided in this application embodiment includes a frame 100, a motor 200, a clamping arm 400, and a swing column 700. The aforementioned covering completely encloses the clamping arm 400 and the swing column 700 within it. It should be understood that the surface of the clamping arm 400 and the swing column 700 covered by the covering is also the massage part of the massager.

[0027] Among them, reference Figure 2 and Figure 5 The frame 100 includes a first support member 110 and a second support member 120, which together form an assembly space for the aforementioned motor 200, clamping arm 400, and swing column 700. The motor 200 is disposed in the assembly space, and an eccentric drive member 300 is connected to the rotating shaft of the motor 200. In some embodiments, the first support member 110 and the second support member 120 are symmetrically arranged.

[0028] At least one clamping arm 400 is provided. The clamping arm 400 includes a driving section 410 and a swinging section 420. A rotating part 430 is provided between the driving section 410 and the swinging section 420. The rotating part 430 is rotatably mounted on the frame 100. A first driving structure 500 is connected between the driving section 410 of the clamping arm 400 and the eccentric driving member 300. The first driving structure 500 can reciprocate in a first direction under the drive of the eccentric driving member 300 to push the driving section 410 of the clamping arm 400 to move in the first direction, thereby causing the driving section 410 to drive the rotating part 430 to rotate relative to the frame 100 so as to realize the reciprocating swinging of the swinging section 420.

[0029] Specifically, for example, the eccentric drive member 300 and the first drive structure 500 can be configured as follows: the eccentric drive member 300 includes at least a drive disk 310 whose center is offset from the axis of rotation of the motor 200; the first drive structure 500 includes a first part 510 and a second part 520. The first part 510 has a groove 511 along a second direction, which is perpendicular to the first direction. The drive disk 310 on the eccentric drive member 300 is slidably disposed in the groove 511 of the first part 510, and the second part 520 is slidably disposed on the frame 100 along the first direction. Furthermore, a connecting shaft 521 is disposed on the second part 520 along the second direction. Thus, when the eccentric drive member 300 rotates with the shaft, the drive disk 310 rotates eccentrically relative to the shaft. The drive disk 310 slides back and forth in the first groove 511 along the second direction, thereby pulling the first drive structure 500 to move back and forth in the first direction.

[0030] refer to Figure 2 and Figure 5 For example, when the first drive structure 500 is configured as described above, the end of the drive section 410 on the clamping arm 400 away from the swing section 420 is provided with an opening groove 411. The opening groove 411 is inserted into the connecting shaft 521 of the second part 520. Thus, when the first drive structure 500 moves back and forth in a straight line along the first direction, the drive section 410 rotates relative to the first drive structure 500. Furthermore, the depth position of the connecting shaft 521 in the opening groove 411 changes with the movement of the first drive structure 500, thereby enabling the drive section 410 to drive the swing section 420 to swing relative to the frame 100.

[0031] refer to Figures 1 to 3 , Figure 5 and Figure 6 In some embodiments, the clamping arm 400 has two pieces, each disposed on both sides of the shaft axis of the motor 200. Each clamping arm 400 is connected to the aforementioned first drive rod structure with respect to the eccentric drive member 300, and the swing column 700 is located in the opening formed between the swing segments 420 of the two clamping arms 400. It should be understood that in this embodiment, the first drive structure 500 connected to each clamping arm 400 has the same structure.

[0032] refer to Figure 7 It is understood that in the embodiment where the clamping arm 400 has two pieces, the eccentric drive member 300 includes two drive disks 310 that are staggered in the height direction. Each drive disk 310 is slidably engaged with the first sliding groove 511511 in each of the first drive structures 500, that is, each of the first drive structures 500 is stacked in the same height direction. Thus, when the eccentric drive member 300 rotates with the rotating shaft, each of the first drive structures 500 can move asynchronously in the first direction, thereby causing the two clamping arms 400 to swing alternately.

[0033] refer to Figure 2 , Figure 5 The swing column 700 is rotatably mounted on the frame 100. A second drive structure 600 connects the swing column 700 and the rotating shaft. The motor 200 drives the free end of the swing column 700 to oscillate omnidirectionally on the frame 100 via the second drive structure 600. Furthermore, the rotation center of the swing column 700 is located on one side of the axis of the motor 200's rotating shaft, and the swing column 700 is tilted relative to the axis of the motor 200's rotating shaft. It should be understood that, generally, the user's grip on the massager is located around the periphery of the motor 200's mounting position. By tilting the swing column 700, the part of the massager that contacts the user's skin is located on one side of the axis of the motor 200's rotating shaft. When the user holds the massager to massage their skin, the massager's axis does not need to be perpendicular to the skin surface to achieve massage, resulting in a more comfortable grip angle.

[0034] Further reference Figures 1 to 3 , Figure 6 In some embodiments, the line connecting the rotation center points of the two clamping arms 400 on the frame 100 is inclined relative to the axis of rotation, and the two clamping arms 400 have different lengths; furthermore, the line connecting the free ends of the two clamping arms 400 is also inclined relative to the axis of rotation. In some specific embodiments, the line connecting the free ends of the two clamping arms 400 is perpendicular to the axis of the swing column 700. With this arrangement, the plane of the opening formed between the free ends of the two clamping arms 400 can be inclined relative to the axis of rotation of the motor 200, that is, the massage part of the massager is inclined relative to the axis of rotation, so that the massager can be easily held by the user during use.

[0035] In some embodiments, a receiving cavity for accommodating the vibration motor 200 is provided on the free end of the swing column 700. With this configuration, when the swing column 700 is driven by the motor 200 to swing omnidirectionally at its free end, the vibration motor 200 can apply high-frequency vibration to the cover, and the surface of the cover can have a vibration effect while achieving wave-like undulation, so as to provide a better massage experience.

[0036] It is understood that, based on the above embodiments, for the pendulum 700, on the projection plane perpendicular to the first direction and parallel to the second direction, the projections of the rotation center of the pendulum 700 and the axis of the rotation shaft overlap.

[0037] It is understood that, based on the above embodiments, the pendulum column 700 and the second drive structure 600 can be implemented in the following ways.

[0038] refer to Figure 3 and Figure 6In the first embodiment, the pendulum column 700 includes a straight section 710 and an inclined section 720. The axis of the inclined section 720 is inclined relative to the axis of the straight section 710, and both the axis of the inclined section 720 and the axis of the straight section 710 are inclined relative to the axis of the motor 200 shaft. The straight section 710 is rotatably connected to the frame 100, for example, a bearing 712 is connected between the peripheral wall of the straight section 710 and the frame 100. Corresponding to the aforementioned embodiment of the pendulum column 700, the eccentric drive member 300 is provided with a connecting column 320 coaxial with the shaft. The second drive structure 600 includes a first bevel gear 610 and a second bevel gear 620 that mesh with each other. The first bevel gear 610 is fixedly disposed on the connecting column 320, and the second bevel gear 620 is fixedly connected to the straight section 710 of the pendulum column 700. With this configuration, when the motor 200 shaft rotates, it can drive the straight section to rotate through the first bevel gear 610 and the second bevel gear 620. Since the axis of the inclined section 720 is inclined relative to the axis of the straight section 710, the rotation of the straight section can drive the inclined section 720 to swing in all directions. For example, the swing trajectory surface of the inclined section 720 is a conical surface, so that the cover can form a ring-shaped wave-like undulating effect.

[0039] refer to Figure 5 Furthermore, a mounting base 711 is provided on the straight section 710, with the bottom surface of the mounting base 711 perpendicular to the axis of the inclined section 720. The inclined section 720 is rotatably mounted on the mounting base 711. Specifically, a bearing 712 is connected between the bottom of the inclined section 720 and the bottom peripheral wall of the mounting base 711. With this arrangement, when the straight section 710 rotates, the inclined section 720 can be driven by the straight section 710 to swing but can maintain its circumferential position in the mounting base 711. When the cover covers the top of the inclined section 720, the friction between the inclined section 720 and the cover can be reduced.

[0040] It is understandable that the aforementioned vibration motor 200 is mounted on the straight section 710 so that it can directly contact the surface of the cover.

[0041] refer to Figure 6 In the second embodiment, the central part of the pendulum column 700 is omnidirectionally mounted on the frame 100; the second drive structure 600 includes a spring 630, which connects the pendulum column 700 and the eccentric drive member 300. It should be understood that the spring 630 is connected to a position on the eccentric drive member 300 that is offset from the axis of rotation. Thus, when the eccentric drive member 300 rotates with the axis of rotation, the torque generated by the deformation of the spring 630 can pull the pendulum column 700 to swing.

[0042] 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.
