Description

Technical Field

[0001] This disclosure relates to the field of health care device technology, and in particular to a transmission mechanism 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 often designed based on the structural characteristics of different parts of the body, such as neck massagers, waist massagers, and shoulder and neck massagers. As people increasingly spend long hours in their work and daily lives, muscle discomfort is common, leading to a growing market demand for massage devices that can provide muscle massage.

[0003] In related technologies, some massage devices can only apply pressure to the human body, resulting in unsatisfactory massage effects. Summary of the Invention

[0004] This disclosure provides a transmission mechanism and a massage device. The transmission mechanism can drive the massage head to perform kneading motions, which helps to improve the massage effect of the massage device.

[0005] The technical solution is as follows: According to a first aspect of the present disclosure, a transmission mechanism is also provided, including a support assembly, a drive assembly, and a linkage assembly. The drive assembly is disposed on the support assembly. The linkage assembly is movably connected to the support assembly, and one end of the linkage assembly is driveably connected to the drive assembly. A movable member is drively connected to the other end of the linkage assembly, and the movable member includes a ball joint rotatably connected to the support assembly and a connecting portion for connecting to a first massage head, the connecting portion being disposed away from the support assembly. The drive assembly is capable of driving the movable member to reciprocate around the ball joint via the linkage assembly.

[0006] The technical solution will be further explained below: In one embodiment, when the movable member reciprocates around the ball joint, the connecting part reciprocates around a first predetermined trajectory, which includes a first closed curve.

[0007] In one embodiment, the linkage assembly includes a track rod, one end of which is movably connected to a movable member, and the other end of which is provided with a first guide post. A bearing assembly is provided with an arc-shaped groove that guides and engages with the first guide post. A drive assembly is drively connected to the other end of the track rod to drive the first guide post to reciprocate along the arc-shaped groove.

[0008] In one embodiment, a gap exists between the first guide post and the arc-shaped groove. The sidewall of the arc-shaped groove includes a first guide surface and a second guide surface spaced apart from the first guide surface. When the first guide post makes guiding contact with the first guide surface and is spaced apart from the second guide surface, the connecting portion moves along a first direction and forms a first trajectory. When the first guide post makes guiding contact with the first guide surface and is spaced apart from the second guide surface, the connecting portion moves along a second direction and forms a second trajectory. The first direction and the second direction are opposite, and the first trajectory and the second trajectory are spaced apart.

[0009] In one embodiment, the sidewall of the arc-shaped groove further includes a first arc-shaped surface connecting one end of the first guide surface and one end of the second guide surface, and a second arc-shaped surface connecting the other end of the first guide surface and the other end of the second guide surface. When the first guide post sequentially engages with the first guide surface, the first arc-shaped surface, the second guide surface, and the second arc-shaped surface, the first trajectory and the second trajectory are connected end to end to form a second closed curve, and the first guide post can reciprocate along the second closed curve.

[0012] And / or, the track rod is also provided with a clearance groove for the moving part, and part of the moving part is inserted into the clearance groove.

[0013] In one embodiment, the first mating part includes a second guide post and two first mounting parts spaced apart and forming notches. The notches communicate with a clearance groove, and each first mounting part has a first mounting hole. The first mounting parts are inserted into the movable part through the notches, so that the first mounting holes are opposite to the first guide groove. The second guide post is inserted into the first mounting holes and the first guide groove, and is fixedly connected to the first mounting parts.

[0014] In one embodiment, the movable component further includes a third guide post disposed below the ball joint, the ball joint being disposed between the third guide post and the connecting part, and one end of the trajectory rod being provided with a second guide groove that guides and cooperates with the third guide post.

[0015] In one embodiment, the linkage assembly further includes a transmission unit, one end of which is rotatably connected to the end of the track rod away from the moving part, and the other end of which is connected to the drive assembly. The drive assembly drives the first guide post to reciprocate along the arc groove through the transmission unit.

[0016] In one embodiment, the drive assembly includes a first eccentric cam rotatably disposed on the bearing assembly and a first drive member sleeved and driven by the first eccentric cam. The first drive member includes a first drive portion that is drivenly connected to one end of the transmission unit away from the track rod. The first eccentric cam is drivenly connected to the first drive member so that the first drive portion can reciprocate along a second set trajectory.

[0017] In one embodiment, the first driving member further includes a transmission ring that engages with the first eccentric cam and a rod protruding from the transmission ring, with the first driving part disposed on the rod.

[0018] In one embodiment, the first drive unit includes a rotating part fixed to one end of the rod, the rotating part being disposed away from the transmission ring. The transmission unit includes a first connecting rod, one end of which is rotatably connected to the rotating part, and the other end of which is rotatably connected to the other end of the track rod.

[0019] In one embodiment, the load-bearing component is provided with a first sliding groove, and the first driving part includes a first rotating protrusion fixed to one end of the rod body. The first rotating protrusion is disposed away from the transmission ring and slides in cooperation with the first sliding groove. The transmission unit includes a slider and a second connecting rod. The slider is slidably connected to the load-bearing component, and one end of the slider is rotatably connected to the rotating part and can slide relative to it. The other end of the slider is rotatably connected to one end of the second connecting rod, and the other end of the second connecting rod is rotatably connected to the other end of the track rod.

[0020] In one embodiment, the drive assembly further includes an active member rotatably disposed on the support assembly and a driven member rotatably disposed on the support assembly. The active member and the driven member are in a transmission cooperation to drive the driven member to rotate. The first eccentric cam is fixedly and transmissionally connected to the driven member and rotates coaxially.

[0021] In one embodiment, the drive assembly further includes a worm gear rotatably disposed on the support assembly and a worm wheel rotatably disposed on the support assembly. The worm gear and the worm wheel are in a transmission engagement, and the worm wheel is fixedly connected to the driving member and rotates coaxially.

[0022] According to a second aspect of the present disclosure, a massage device is also provided, including a power source, a first massage head, and a transmission mechanism as described in any of the above embodiments. The first massage head is connected to a connecting portion, and the power source is disposed on a bearing component and is connected to a driving component for transmission, so as to drive the first massage head to move through the driving component.

[0023] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects: When in use, the power source transmits power to the linkage assembly via the drive assembly. The linkage assembly then converts this power into a driving force for the reciprocating motion of the movable part around the ball joint, which is then converted into a massage force by the first massage head. Because the movable part can reciprocate around the ball joint, the first massage head can also perform a kneading motion around the ball joint, thereby simulating a human hand massage and improving the massage effect of the device.

[0043] 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.

[0044] 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.

[0045] Massage devices, as health care tools 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 often designed based on the structural characteristics of different parts of the body, such as neck massagers, waist massagers, and so on. Currently, there are numerous types and brands of massage devices available, giving consumers a wide range of choices. Therefore, how to win consumer favor and enhance product competitiveness has become an increasingly important issue for massage device manufacturers.

[0046] Currently, with the increasing prevalence of sedentary work and lifestyles, people are prone to discomfort in areas such as the neck, shoulders, back, waist, and hips, leading to a growing market demand for massage devices that can provide body massage. However, current technologies typically only apply pressure to the body, resulting in less than ideal massage effects.

[0047] For example, traditional massage devices are designed to fit the curves of the neck and shoulders, allowing for the use of movable neck and shoulder massagers to massage and relax the muscles, effectively relieving neck and shoulder fatigue. However, these devices only provide pressure to the neck and shoulders, resulting in less than ideal massage effects. Similarly, some back massage heads achieve back pressure through oscillation or by rotating the device itself. These types of massage heads struggle to achieve a kneading effect, leading to a significant difference in massage results compared to human hand massage, thus resulting in less than ideal massage effects.

[0048] Therefore, it is necessary to provide a transmission mechanism that can drive the massage head to perform kneading motion, which is beneficial to improving the massage effect of the massage device.

[0049] To better understand the transmission mechanism of this disclosure, it is illustrated by using a massage device that applies the transmission mechanism.

[0050] like Figure 1 as well as Figure 2 As shown, in some embodiments, a massage device 1 is provided, including a first massage head 10, a power source 20, and a transmission mechanism 30. Thus, the power source 20 drives the first massage head 10 to move through the transmission mechanism 30.

[0051] Among them, such as Figure 2 as well as Figure 3As shown, the transmission mechanism 30 includes a support assembly 100, a drive assembly 200, and a linkage assembly 300. The drive assembly 200 is disposed on the support assembly 100. The linkage assembly 300 is movably connected to the support assembly 100, and one end of the linkage assembly 300 is driveably connected to the drive assembly 200. The movable member 400 is driveably connected to the other end of the linkage assembly 300. The movable member 400 includes a ball joint 410 rotatably connected to the support assembly 100 and a connecting portion 420 for connecting to the first massage head 10. The connecting portion 420 is disposed away from the support assembly 100. The drive assembly 200 can drive the movable member 400 to reciprocate around the ball joint 410 via the linkage assembly 300. Thus, when the massage device 1 is in use, the power source 20 transmits power to the linkage assembly 300 via the drive assembly 200, and the linkage assembly 300 converts this power into a driving force for the movable member 400 to reciprocate around the ball joint 410, which is then converted into a massage force by the first massage head 10. Since the movable part 400 can reciprocate around the ball joint 410, the first massage head 10 can also perform kneading motion around the ball joint 410, thereby simulating the massage of a human hand, which helps to improve the massage effect of the massage device 1.

[0052] It should be noted that the ball joint 410 can be implemented in various ways, including a ball joint or a ball joint hole, as long as it can be ball-jointed with the bearing component 100.

[0053] In some embodiments, when the movable member 400 reciprocates around the ball joint 410, the connecting part 420 reciprocates around a first predetermined trajectory, which includes a first closed curve. Thus, the connecting part 420 can rotate back and forth around the first closed curve, thereby enabling the first massage head 10 to also reciprocate around the closed curve, facilitating a kneading massage effect.

[0054] It should be noted that the first closed curve includes a two-dimensional closed curve (e.g., a circular curve, or an elliptical curve), or a three-dimensional closed curve (e.g., an elliptical trajectory curved around a convex surface of a sphere), etc.

[0055] Furthermore, the design of the first closed curve can be flexibly tailored to the characteristics of the human body's curves, and its specific implementation methods include spiral curves, circular curves, and so on. For example, the first massage head can knead the shoulders along the first closed curve. Or, the first massage head can design a first closed curve based on the curve of the back to knead the back. Or, the first massage head can design a first closed curve based on the curve of the waist to knead the waist. Or, the first massage head can design a first closed curve based on the curve of the buttocks to knead the buttocks. Or, the first massage head can design a first closed curve based on the curve of the thighs to knead the thighs.

[0056] It should be noted that the first closed curve can be flexibly designed according to the curve of the body part to be massaged, as long as it can simulate the kneading massage effect of human hands. For example, when using the first massage head to massage the shoulders, the first closed curve includes a first circular curve that can move from the scapula towards the spine, reach a first preset position, and then move towards the neck. After reaching a second preset position above the first preset position, it moves again from the spine towards the scapula. This process is repeated to achieve kneading. Of course, the movement can also be reversed, moving from the spine towards the scapula to the second preset position... Alternatively, the first closed curve moves from the initial position down the rhomboid muscles (or other shoulder muscles) towards the back, then towards the spine, then towards the neck, and finally back to the initial position. This is repeated to achieve the kneading effect. Of course, the movement can also be reversed, moving from the initial position towards the neck… For example, when using the first massage head for a back massage, the first closed curve includes a second annular curve, which can move from the side of the body towards the spine, reach a first preset position, and then move towards the neck. After reaching a second preset position above the first preset position, it moves again from the spine towards the side of the body. This process is repeated to achieve kneading. Of course, the movement can also be reversed.

[0057] Alternatively, the first closed curve moves from the initial position down the latissimus dorsi (or other back muscles) towards the hips, then towards the spine, then towards the shoulders, and finally back to the initial position. This repeated motion achieves the kneading effect. Of course, the movement can also be reversed.

[0058] It should be noted that there is no limit to the number of the first massage heads, including but not limited to 1, 2, 3, etc., which can be flexibly designed according to actual massage needs.

[0059] For example, when the first massage head is used to massage the human shoulder, if there are two first massage heads, they can be driven by the movement of the second massage member to massage the upper and lower parts of the human shoulder simultaneously.

[0060] For example, when the first massage head is used to massage the back of the human body, if there are three first massage heads, the movement of the first massage head can drive the three first massage heads to massage the upper, middle and lower parts of the back at the same time.

[0061] like Figure 2 as well as Figure 3 As shown, the connecting part 420 reciprocates around the first closed curve to drive the first massage head 10 to knead and massage the shoulders and neck of the human body.

[0062] like Figure 4as well as Figure 8 As shown, the connecting part 420 reciprocates around the first closed curve to drive the first massage head 10 to knead and massage the back of the human body.

[0063] It should be noted that "kneading massage" should be interpreted broadly, including back-and-forth swaying, back-and-forth rotation, and back-and-forth movement along a set trajectory. The massage intensity on the human muscles can be applied back and forth from light to heavy.

[0064] like Figure 2 as well as Figure 3 As shown, or Figures 4 to 10 As shown, in some embodiments, the linkage assembly 300 includes a track rod 310, one end of which is movably connected to the movable member 400, and the other end of which is provided with a first guide post 311. The bearing assembly 100 is provided with an arc-shaped groove 110 that guides and engages with the first guide post 311. The drive assembly 200 is drively connected to the other end of the track rod 310 to drive the first guide post 311 to reciprocate along the arc-shaped groove 110.

[0065] like Figures 7 to 9 As shown, in some embodiments, a gap 101 exists between the first guide post 311 and the arc-shaped groove 110. The sidewall of the arc-shaped groove 110 includes a first guide surface 111 and a second guide surface 112 spaced apart from the first guide surface 111. When the first guide post 311 is in guiding contact with the first guide surface 111 and spaced apart from the second guide surface 112, the connecting part 420 moves along a first direction and forms a first trajectory. When the first guide post 311 is in guiding contact with the first guide surface 111 and spaced apart from the second guide surface 112, the connecting part 420 moves along a second direction and forms a second trajectory. The first direction and the second direction are opposite, and the first trajectory and the second trajectory are spaced apart. Thus, through the cooperation of the first trajectory and the second trajectory, the first guide post 311 of the trajectory rod 310 can also deflect along the width direction of the arc-shaped groove 110 during its movement along the length direction, making it easier to drive the connecting part 420 to move along a first closed curve.

[0066] like Figure 8As shown, in some embodiments, the sidewall of the arc-shaped groove 110 also includes a first arc-shaped surface 113 connecting one end of the first guide surface 111 and one end of the second guide surface 112, and a second arc-shaped surface 114 connecting the other end of the first guide surface 111 and the other end of the second guide surface 112. When the first guide post 311 sequentially guides and engages with the first guide surface 111, the first arc-shaped surface 113, the second guide surface 112, and the second arc-shaped surface 114, the first trajectory and the second trajectory are connected end to end to form a second closed curve, and the first guide post 311 can reciprocate along the second closed curve. Thus, during the movement of the first guide post 311 of the trajectory rod 310 along the arc-shaped groove 110, it can reciprocate around the second closed curve, thereby enabling the trajectory rod 310 to drive the connecting part 420 to move along the first closed curve.

[0067] See you later Figure 2 as well as Figure 3 As shown, in some embodiments, the movable member 400 further includes a first guide portion 430 disposed between the ball joint portion 410 and the connecting portion 420, and one end of the trajectory rod 310 is provided with a first mating portion 312 that guides and engages with the first guide portion 430. Thus, through the engagement of the first guide portion 430 and the first mating portion 312, the trajectory rod 310 can drive the connecting member to reciprocate around the ball joint portion 410.

[0068] Optionally, such as Figure 6 as well as Figure 7 As shown, in some embodiments, one of the first guide portion 430 and the first mating portion 312 is provided with a first guide groove 431, and the other is provided with a second guide post 3121 that is guided and mated with the first guide groove 431.

[0069] Optionally, such as Figure 6 as well as Figure 7 As shown, in some embodiments, the track rod 310 is also provided with a clearance groove 313 for the movable member 400, and a portion of the movable member 400 is inserted into the clearance groove 313.

[0070] like Figure 6 as well as Figure 7As shown, in some embodiments, the first mating part 312 includes a second guide post 3121 and two first mounting parts 3122 spaced apart and forming a notch 3002. The notch 3002 communicates with the clearance groove 313, and the first mounting part 3122 is provided with a first mounting hole 3001. The first mounting part 3122 is inserted into the movable part 400 through the notch 3002, so that the first mounting hole 3001 is opposite to the first guide groove 431. The second guide post 3121 is inserted into the first mounting hole 3001 and the first guide groove 431, and is fixedly connected to the first mounting part 3122. In this way, the trajectory rod 310 and the movable part 400 are nested and mated with each other, and can be mated with the first guide groove 431 through the second guide post 3121, so that when the trajectory rod 310 moves along the arc groove 110, it can push the movable part 400 to swing up and down, and deflect to the left and right during the up and down swing, thereby causing the connecting part 420 to reciprocate around the first closed curve.

[0071] like Figure 11 as well as Figure 12 As shown, in some embodiments, the movable member 400 further includes a third guide post 440 disposed below the ball joint 410. The ball joint 410 is disposed between the third guide post 440 and the connecting part 420. One end of the trajectory rod 310 is provided with a second guide groove 314 that guides and engages with the third guide post 440. Thus, by engaging the third guide post 440 with the second guide groove 314, the trajectory rod 310 can move along the arcuate groove 110, pushing the movable member 400 to swing up and down, and deflecting left and right during the up-and-down swing, thereby causing the connecting part 420 to reciprocate around the first closed curve.

[0072] See you later Figure 2 as well as Figure 3 As shown, or Figures 4 to 10 As shown, in some embodiments, the linkage assembly 300 further includes a transmission unit 320. One end of the transmission unit 320 is rotatably connected to the end of the track rod 310 away from the movable member 400, and the other end of the transmission unit 320 is drively connected to the drive assembly 200. The drive assembly 200 drives the first guide post 311 to reciprocate along the arc-shaped groove 110 through the transmission unit 320. Thus, by setting the transmission unit 320, the positions of the drive assembly 200 and the track rod 310 can be flexibly set, making their design more flexible.

[0073] like Figure 2 as well as Figure 3 As shown, or Figure 6 , Figure 7 as well as Figure 10As shown, in some embodiments, the drive assembly 200 includes a first eccentric cam 210 rotatably disposed on the support assembly 100 and a first drive member 220 sleeved and driven by the first eccentric cam 210. The first drive member 220 includes a first drive portion 221 drivenly connected to one end of the transmission unit 320 away from the track rod 310. The first eccentric cam 210 is drivenly connected to the first drive member 220 so that the first drive portion 221 can reciprocate along a second predetermined trajectory. Thus, by drivingly connecting the first drive member 220 to the first eccentric cam 210, the eccentric motion of the first eccentric cam 210 is easily converted into the reciprocating motion of the first drive portion 221 along the second predetermined trajectory, which can generate a reciprocating driving force and prevent the connecting rod assembly 300 from interfering with the shaft of the first eccentric cam 210.

[0074] It should be noted that the "second set trajectory" includes a straight trajectory or an arc trajectory, etc., which can be specifically implemented according to the transmission and engagement structure between the first driving member 220 and the first eccentric cam 210. In some embodiments, the first driving member 220 also includes a transmission ring 222 that is sleeved and engaged with the first eccentric cam 210, and a rod 223 protruding from the transmission ring 222, with the first driving part 221 disposed on the rod 223. In this way, through the transmission ring 222 sleeved and engaged with the first eccentric cam 210, it is convenient to use the eccentric driving force of the first eccentric cam 210 to drive the rod 223 to reciprocate, thereby enabling the first driving part 221 to move along the set trajectory.

[0075] like Figure 2 as well as Figure 3 As shown, in some embodiments, the first driving unit 221 includes a rotating part 2211 fixed to one end of the rod body 223, and the rotating part 2211 is disposed away from the transmission ring 222. The transmission unit 320 includes a first connecting rod 321, one end of which is rotatably connected to the rotating part 2211, and the other end is rotatably connected to the other end of the trajectory rod 310. Thus, the first driving unit 221 drives the first connecting rod 321 to extend and retract through the rotating part 2211, thereby increasing the extension and retraction driving force for the movement of the trajectory rod 310.

[0076] Reference Figure 3 As shown, when the first eccentric wheel 210 rotates clockwise, it drives the first drive unit 211 to swing and drives the first connecting rod 321 to push the track rod 310 around the arc groove 110 in the direction of approaching the moving part 400, thereby driving the first massage head 10 to move in the direction of approaching the support component 100.

[0077] like Figures 6 to 8In some embodiments shown, the support assembly 100 is provided with a first slide groove 140, and the first driving part 221 includes a first rotating protrusion 2212 fixed to one end of the rod body 223. The first rotating protrusion 2212 is disposed away from the transmission ring 222 and slides in cooperation with the first slide groove 140. The transmission unit 320 includes a slider 322 and a second connecting rod 323. The slider 322 is slidably connected to the support assembly 100, and one end of the slider 322 is rotatably connected to the rotating part 2211 and can slide relative to it. The other end of the slider 322 is rotatably connected to one end of the second connecting rod 323, and the other end of the second connecting rod 323 is rotatably connected to the other end of the track rod 310. Thus, by sliding the first rotating protrusion 2212 in cooperation with the first slide groove 140, the slider 322 is driven to reciprocate and extend in a set direction. This allows the extension force of the slider 322 to drive the track rod 310 to move along the arc groove 110 via the second connecting rod 323, thereby driving the first massage head 10 to perform kneading motion.

[0078] Understandably, the above structure makes it easy to generate a drive trajectory rod 310 to drive the connecting part 420 to move along the first closed curve, thereby realizing the kneading motion of the first massage head 10.

[0079] Reference Figure 7 As shown, when the first eccentric wheel 210 rotates clockwise, it drives the first drive unit 211 to swing and drives the first slider to slide towards the first eccentric wheel 210, and drives the second connecting rod 323 to pull the track rod 310 around the arc groove 110 in a direction away from the moving part 400, and can drive the first massage head 10 to move towards the bearing assembly 100.

[0080] like Figure 2 as well as Figure 3 ,or Figure 6 as well as Figure 10 As shown, or Figure 11 as well as Figure 12 As shown, in some embodiments, the drive assembly 200 further includes a driving member rotatably disposed on the support assembly 100 and a driven member rotatably disposed on the support assembly 100. The driving member and the driven member are in a transmission cooperation to drive the driven member to rotate. The first eccentric cam 210 is fixedly and transmissionally connected to the driven member and rotates coaxially. In this way, the driving member drives the first eccentric cam 210 to rotate through the driven member, so that the first eccentric cam 210 can be flexibly disposed around the driving wheel 230, making full use of the area space of the support assembly 120.

[0081] It should be noted that there are several ways to specifically implement "the driving wheel 230 driving the driven wheel 240 to rotate". For example, the driving wheel 230 can drive the driven wheel 240 to rotate through a flexible connecting rod (that is, forming a flexible transmission component such as a belt drive assembly or a chain drive assembly). Another example is... Figure 2as well as Figure 3 ,or Figure 6 as well as Figure 10 As shown, or Figure 11 as well as Figure 12 As shown, in some embodiments, the driving wheel 230 is a driving gear, and the driven member is a driven gear that meshes with the driving gear. This improves the transmission accuracy and reliability between the driving wheel 230 and the driven wheel 240, which is beneficial for extending the service life of the massage device 1.

[0082] Alternatively, in some embodiments, the driving gear and the driven gear mesh directly, which can reduce the transmission distance and make the structure of the drive mechanism more compact.

[0083] In other embodiments, the driving gear can also be indirectly meshed with the driven gear through the transmission gear, so that the position between the driving gear and the driven gear can be flexibly set, reducing the difficulty of arranging the massage device 1.

[0084] Optionally, in some embodiments, the first eccentric cam 210 is integrally formed and fixed with the follower. This reduces assembly steps and improves the assembly efficiency of the drive mechanism.

[0085] It should be noted that the power source 20 can be implemented in various ways, as long as it can output rotational power to drive the driving component to rotate. For example, the power source 20 includes a motor. In addition, the power source 20 can be directly connected to the driving component for transmission, or it can be connected to the driving component for transmission through other transmission structures.

[0086] like Figure 2 as well as Figure 3 ,or Figure 6 as well as Figure 10 As shown, or Figure 11 as well as Figure 12 As shown, in some embodiments, the drive assembly 200 further includes a worm 250 rotatably disposed on the support assembly 100 and a worm wheel 260 rotatably disposed on the support assembly 100. The worm 250 and the worm wheel 260 are in a transmission engagement, and the worm wheel 260 is fixedly and transmissionally connected to the driving member and rotates coaxially. In this way, the transmission connection between the power source 20 and the driving wheel 230 is achieved by utilizing the engagement of the worm 250 and the worm wheel 260, allowing the power source 20 to be flexibly positioned radially on the driving wheel 230, reducing the difficulty of arranging the power source 20.

[0087] like Figures 4 to 6As shown, the support assembly 100 includes a support member 120 for supporting the drive gear, driven gear, first eccentric cam 210, second drive member 270, first drive member 220, and transmission assembly, and a protective shell 130 that cooperates with the support member 120 to protect the drive gear, driven gear, worm 250, and worm wheel 260. This prevents foreign objects from entering the transmission gaps of the drive gear and driven gear, or the transmission gaps of the transmission assembly, which could cause damage or jamming. This effectively improves the protective performance of the massage device 1, thereby extending its service life.

[0088] like Figure 4 As shown, the protective shell 130 is provided with a clearance notch 131 to avoid the first drive unit 221. This facilitates the first drive unit 221 to pass through the clearance notch 131 and connect with the linkage unit of the second massage assembly to drive the second massage member 40 to move.

[0089] like Figures 4 to 6 As shown, in some embodiments, the drive assembly 200 further includes a second drive member 270 coaxially connected to the driven member. The second drive member 270 protrudes from the driven wheel 240 away from the first eccentric cam 210 and is connected to the second massage member 40. Thus, when the massage device 1 is in use, the first massage head 10 is mounted on the movable member 400, while the second massage member 40 is movably mounted on the support assembly 100 and driven by the second drive member 270. This allows the second massage member 40 to be arranged axially along the rotation axis of the driven member, while the first massage head 10 is arranged radially along the rotation axis of the driven member, providing sufficient space for movement between them. Furthermore, the power source 20 is connected to the worm gear 250, facilitating the transmission of power from the power source 20 to the driving member. The driving member then drives the driven member to rotate, transmitting power to the second drive member 270 and the first drive member 220 respectively. This converts a single input power into two driving powers, each driving one massage member to rotate.

[0090] In some embodiments, the massage device 1 further includes a locking fastener 500 disposed between the connecting portion 420 and the first massage head 10. The connecting portion 420 is movably connected to the support assembly 100, and the first massage head 10 is rotatably connected to the connecting portion 420. The locking fastener 500 has a released state in which the first massage head 10 is released and a locked state in which the first massage head 10 is fixed to the connecting portion 420. When the locking fastener 500 is in the released state, the first massage head 10 is rotatable relative to the connecting portion 420.

[0091] When a user needs a neck and shoulder massage, the locking fastener 500 secures the first massage head 10 to the connecting part 420 and activates the power source, allowing the first massage head 10 to massage the user's neck and shoulders (or back, shoulders, etc.) via the connecting part 420. During this process, if the user feels that the massage range of the first massage head 10 cannot reach the uncomfortable areas of the neck and shoulders, the user can operate the locking fastener 500 to release the first massage head 10, allowing it to rotate relative to the connecting part 420 and around the neck and shoulders. After adjusting the first massage head 10 to the desired position, the locking fastener 500 is operated again to secure the first massage head 10 to the connecting part 420. The power source 20 is then activated again, allowing the first massage head 10 to massage the user's uncomfortable areas via the connecting part 420. Thus, the position of the massage head of the massage device 1 is adjustable, meeting the user's massage needs for different areas of the neck and shoulders, thereby improving the user experience of the massage device 1.

[0092] It should be noted that "shoulder and neck" should be interpreted broadly, including the area where the shoulder and neck meet, or at least one of the lower part of the neck and the upper part of the shoulder, encompassing the area containing the upper part of the trapezius muscle, or the area containing the upper part of the trapezius muscle and the levator scapulae muscle. Understandably, refer to... Figure 2 As shown, the neck and shoulder area is a common source of neck and shoulder pain and stiffness, typically including the sides of the neck and the back. Traditional massage devices 1 usually only massage the sides of the neck or the back of the cervical spine, offering limited massage options and failing to meet the user's needs for different areas of the neck and shoulder. However, by adjusting the position of the first massage head 10 relative to the connecting part 420, the massage device 1 of this disclosure can massage both the sides of the neck and the back of the cervical spine.

[0093] It should be noted that the locking device 500 can be implemented in various ways, including but not limited to elastic locking, threaded locking, snap locking, etc.

[0094] like Figures 13 to 15As shown, in some embodiments, the locking fastener 500 includes an elastic member 510 disposed on one of the connecting portion 420 and the first massage head 10, and a protrusion 520 fixed on the elastic member 510. The other of the connecting portion 420 and the first massage head 10 is provided with a plurality of anti-rotation holes 422 spaced apart along a circumferential direction. When the locking fastener 500 is in the loose state, the elastic member 510 is in a non-reset state, allowing the protrusion 520 to separate from the anti-rotation hole 422. When the locking fastener 500 is in the locked state, the elastic member 510 is in a reset state, allowing the protrusion 520 to be inserted and fixed into the anti-rotation hole 422. Thus, when it is necessary to adjust the position of the first massage head 10, force is applied directly or indirectly to the elastic member 510, causing the elastic member 510 to displace and causing the protrusion 520 to separate from the corresponding anti-rotation hole 422, thereby loosening the locking fastener 500 and facilitating the rotation of the first massage head 10. After adjusting the first massage head 10 to a suitable position, the protrusion 520 is positioned opposite to the other anti-rotation hole 422. The elastic element 510 is then released, causing it to reset and insert the protrusion 520 into the other anti-rotation hole 422, thus locking the first massage head to the connecting part 420. This method is easy to implement and simple to operate.

[0095] It should be noted that rings include circles, ellipses, and polygonal rings, etc.

[0096] Optionally, the elastic element 510 is disposed on the connecting portion 420, and the anti-rotation hole 422 is disposed on the first massage head 10.

[0097] Optionally, the elastic element 510 is disposed on the first massage head 10, and the anti-rotation hole 422 is disposed on the connecting part 420.

[0098] Furthermore, in some embodiments, the first massage head 10 is provided with a rotating body 11, and the connecting portion 420 is provided with a mating hole 421 that rotatably engages with the rotating body 11. An anti-rotation hole 422 is provided in the connecting portion 420 and communicates with the mating hole 421. An elastic member 510 is provided in the rotating body 11 so that the protrusion 520 is movably disposed between the mating hole 421 and the anti-rotation hole 422. Thus, the first massage head 10 and the connecting portion 420 are rotatably connected by the rotating body 11 and the mating hole 421. By providing the elastic member 510 in the rotating body 11, it can be inserted into the mating hole 421 as the rotating body 11 is inserted, allowing the protrusion 520 to be movably disposed between the anti-rotation hole 422 and the mating hole 421. This facilitates the separation or insertion / fixing of the protrusion 520 from the anti-rotation hole 422 by the elastic member 510. This ensures that the elastic element 510 fits tightly with the first massage head 10 and the connecting part 420, and that the installation is reliable.

[0099] Optionally, in some embodiments, the elastic element 510 is in the form of a spring sheet. At least one of the sidewalls of the rotating body 11 and the mating hole 421 is provided with a relief groove 11a, and the elastic element 510 can move and / or deform within the relief groove 11a, so that the elastic element 510 can switch between a non-reset state and a reset state. In this way, the elastic element 510 is in the form of a spring sheet, which is easy to assemble into the relief groove 11a, and can move and / or deform within the relief groove 11a, providing an elastic reset force for the protrusion 520 to reset to be fixed in place with the anti-rotation hole. Moreover, it does not affect the rotation of the rotating body 11 and the mating hole 421.

[0100] Optionally, in some embodiments, the clearance groove 11a is provided on the rotating body 11. This facilitates full utilization of the internal space of the rotating body 11 to provide the clearance groove 11a, so that the connecting part 420 and the rotating body 11 are smaller in size and more compact in structure while meeting strength requirements.

[0101] like Figure 14 as well as Figure 15 As shown, in some embodiments, the elastic element 510 includes a spring body 511 disposed in the clearance groove 11a, a connecting body 512 bent and connected to the spring body 511, and a force-applying body 513 bent and connected to the spring body 511. The connecting body 512 is fixedly connected to the end of the rotating body 11, and at least a portion of the force-applying body 513 is located outside the mating hole 421. Thus, the spring body 511 can be easily disposed on the rotating body 11 by the connecting body 512, and when the rotating body 11 is inserted into the mating hole 421, it will also drive the spring body 511 to be inserted into the mating hole 421, making it easy to pre-tighten the spring body 511, so that the protrusion 520 and the anti-rotation hole 422 can be reliably stopped and engaged.

[0102] It should be noted that there are various ways to connect the connecting part 420 to the support component 100 and the trajectory rod 310, as long as the connecting part 420 can drive the first massage head 10 to move along a set trajectory. The set trajectory includes straight lines, arcs, and closed curves, etc.

[0103] 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.
