[0004] This disclosure provides a drive mechanism and a massage device. The drive mechanism has multiple drive units with a large range of motion between them, allowing for flexible design of the drive method between the multiple massage components to adapt to the required movement patterns of the multiple massage components and improve the massage effect of the massage device.

The second drive member includes a second drive portion for driving the movement of a second massage assembly, and the second drive member is driveably connected to the first eccentric cam so that the second drive portion can reciprocate along a predetermined trajectory.

[0007] The technical solution will be further explained below:

[0008] In one embodiment, the second driving member further includes a transmission ring that engages with the first eccentric cam and a rod protruding from the transmission ring, with the second driving part disposed on the rod.

[0009] In one embodiment, the bearing assembly is provided with a slide groove, and the second drive 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 slide groove.

[0010] Alternatively, the second drive unit includes a ball joint disposed at one end of the rod body, with the ball joint disposed at the end away from the transmission ring, for driving the movement of the second massage component.

[0011] In one embodiment, the second drive unit includes a first connector having a first groove and a second connector having a second groove. The first connector is fixedly connected to the rod body, and the first connector and the second connector are fixedly connected so that the first groove and the second groove cooperate to form a hole-shaped ball joint.

[0012] And / or, the second drive unit further includes a second rotating protrusion for driving the third massage assembly, the second rotating protrusion being fixed to the rod body and disposed between the ball joint and the transmission ring.

[0013] In one embodiment, one of the first and second connectors has at least two through holes spaced apart at the outer edge of the ball joint, and the other has an internally threaded hole corresponding to each of the through holes. The drive assembly includes fasteners corresponding to each of the through holes, which pass through the through holes and are screwed into the internally threaded holes to fix the first and second connectors together.

[0014] In one embodiment, the first eccentric cam is integrally formed and fixed with the driven wheel.

[0015] And / or, the first driving component includes a first rotating shaft, the first rotating shaft includes a transmission body and a first shaft body rotatably connected to the bearing assembly, one end of the transmission body is fixed to the shaft body, the first driving part is fixed to the other end of the transmission body, and the first eccentric cam and the driven wheel are provided with mating holes for fixed transmission engagement with the transmission body.

[0016] In one embodiment, the first rotating shaft further includes a second shaft body, one end of which is fixedly connected to the other end of the transmission body, and the first driving part further includes a second eccentric cam that is fixedly and transmissionally connected to the other end of the second shaft body.

[0017] In one embodiment, the second eccentric cam has an inclined end face at the end away from the driven wheel for pushing against and driving the first massage component to rotate.

[0018] In one embodiment, the transmission assembly includes a worm gear for transmission connection to a power source and a turbine gear rotatably mounted on a support assembly. The worm gear is rotatably mounted on the support assembly and engages with the turbine gear in a transmission drive, while the turbine gear is fixedly connected to a drive wheel to drive the drive wheel to rotate coaxially.

[0019] And / or, the driving gear is the driving gear, and the driven gear is the driven gear that meshes with the driving gear for transmission.

[0020] According to a second aspect of the present disclosure, a massage device is also provided, including a power source, a first massage component, a second massage component, and a drive mechanism as described in any of the above embodiments. The power source is driven to a drive wheel to rotate the drive wheel.

[0022] In use, the massage device features a first massage element movably mounted on a first driving component, and a second massage element movably mounted on a supporting assembly. The second driving component drives the first massage element, arranging it axially along the rotation axis of the driven wheel, while the second massage element is arranged radially along the rotation axis of the driven wheel, ensuring sufficient space for movement between them. Furthermore, since the first driving component (with its first driving part) and the second driving component (with its second driving part) are respectively connected to the driven wheel, the first driving part generates rotational driving force, and the second driving part generates reciprocating driving force along a predetermined trajectory. This allows for flexible design of the driving method between the first and second massage elements to accommodate the movement of at least two massage elements, improving the massage effect. Additionally, the power source is connected to the driving wheel, facilitating the transmission of power from the power source to the driving wheel. The driving wheel then drives the driven wheel to rotate, transmitting power to both the first and second driving parts, converting a single input power into two driving forces. This saves power, resulting in a compact structure and contributing to the miniaturization of the massage device.

Detailed Implementation

[0035] 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.

[0036] 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.

[0037] 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.

[0038] Currently, with the increasing prevalence of sedentary work and lifestyles, people are prone to neck and / or shoulder discomfort, leading to a growing market demand for massage devices that can massage these areas. For example, a shoulder and neck massager is specifically designed for the curves of the shoulder and neck. It uses shoulder massagers to massage and relax shoulder muscles, effectively relieving shoulder muscle fatigue. Simultaneously, it uses neck massagers to massage and relax neck muscles, effectively relieving neck muscle fatigue.

[0039] In related technologies, to save costs and achieve miniaturization, most massage devices utilize a single power source to drive at least two massage elements. However, the inherent limitations of traditional drive mechanisms restrict the driving methods between the massage elements, hindering the improvement of the massage effect. For example, some massage devices with two synchronously moving massage elements typically integrate the driving power of both elements into a drive unit with two eccentric cams. While this ensures a tight fit between the two massage elements and the drive unit, the direction of rotation of the drive unit makes it difficult to adjust the driving method between the massage elements, thus limiting the massage movement patterns, such as the difficulty in achieving dual kneading motion.

[0040] Therefore, it is necessary to provide a drive mechanism. This drive mechanism has multiple drive units with a large range of motion between them, allowing for flexible design of the drive method between the multiple massage components to adapt to the required movement patterns of the multiple massage components and improve the massage effect of the massage device.

[0041] To better understand the drive mechanism of this disclosure, it is illustrated by a massage device that uses the drive mechanism.

[0042] like Figure 1 As shown, in some embodiments, a massage device 1 is provided, including a power source 10, a first massage component 20, a second massage component 30, and a drive mechanism 40. Thus, the power source 10 can simultaneously drive the first massage component 20 and the second massage component 30 to move via the drive mechanism 40.

[0043] Among them, such as Figures 2 to 4As shown, the drive mechanism 40 includes a support assembly 100 and a drive assembly 200. The drive assembly 200 includes a drive wheel 210, a driven wheel 220 rotatably mounted on the support assembly 100, a first eccentric cam 230, a first drive member 240, and a second drive member 250. The drive wheel 210 is rotatably mounted on the support assembly 100 and can drive the driven wheel 220 to rotate. The first eccentric cam 230 and the first drive member 240 are fixedly and transmissionally connected to the driven wheel 220 and rotate coaxially with the driven wheel 220. The first drive member 240 includes a first drive section 241. The first drive section 241 and the first eccentric cam 230 are spaced apart on both sides of the driven wheel 220 along the thickness direction of the driven wheel 220. The second drive member 250 includes a second drive section 251, which is transmissionally connected to the first eccentric cam 230 so that the second drive section 251 can reciprocate along a set trajectory.

[0044] Combination Figure 1 as well as Figure 2 It is understood that the power source 10 is connected to the drive wheel 210 via a transmission connection to drive the drive wheel 210 to rotate. The first massage assembly 20 includes a first massage element 21 movably connected to the first drive member 240, and a first drive unit 241 is connected to the first massage assembly 20 via a transmission connection to drive the first massage element 21 to move. The second massage assembly 30 includes a second massage element 31 movably connected to the support assembly 100, and a second drive unit 251 is connected to the second massage assembly 30 via a transmission connection to drive the second massage element 31 to move.

[0045] When the massage device 1 is in use, the first massage element 21 is movably mounted on the first drive element 240, and the second massage element 31 is movably mounted on the support assembly 100, and is driven by the second drive element 250. This allows the first massage element 21 to be arranged axially along the rotation axis of the driven wheel 220, and the second massage element 31 to be arranged radially along the rotation axis of the driven wheel 220, thus providing sufficient space for movement between them. Furthermore, since the first drive element 240 with the first drive part 241 and the second drive element 250 with the second drive part 251 are respectively connected to the driven wheel 220, the first drive part 241 can generate a rotational driving force, and the second drive part 251 can generate a reciprocating driving force along a set trajectory. This allows the driving method between the first massage element 21 and the second massage element 31 to be flexibly designed to adapt to the movement patterns required by at least two massage elements, thereby improving the massage effect of the massage device 1. Furthermore, the power source 10 is connected to the worm gear 310 for transmission, facilitating the transmission of power from the power source 10 to the drive wheel 210. The drive wheel 210 then drives the driven wheel 220 to rotate, transmitting power to the first drive unit 241 and the second drive unit 251 respectively. This allows the input power to be converted into two driving forces. Consequently, the power source 10 is saved, resulting in a more compact structure for the massage device 1 and contributing to its miniaturization.

[0046] Understandably, since the first and second driving components are fixed to the driven wheel 220 as independent components, the structural design of the first and second driving parts is more flexible, facilitating flexible design according to the driving method required by the massage component. Furthermore, as... Figure 2 As shown, the first driving part and the second driving member are spaced apart on both sides of the driven wheel 220, allowing the first notch to protrude from the driven wheel 220. This reduces interference from the driven wheel 220 to the second driving part and facilitates the use of the thickness space of the driven wheel 220 to accommodate the first massage component. The second driving member is positioned between the driven wheel 220 and the bearing surface of the support component, allowing full utilization of the area space of the support component to accommodate the second driving member and the related structures of the second massage component that are connected to the second driving member. This allows the transmission component, the first massage component, and the second massage component to be flexibly arranged on the support component, minimizing the arrangement difficulty while maintaining a compact structure.

[0047] It should be noted that there are several ways to specifically implement "the driving wheel 210 driving the driven wheel 220 to rotate". For example, the driving wheel 210 can drive the driven wheel 220 to rotate through a flexible transmission component (that is, forming a flexible transmission component 300 such as a belt drive assembly 300 or a chain drive assembly 300). Another example is... Figures 2 to 4As shown, in some embodiments, the driving wheel 210 is a driving gear, and the driven wheel 220 is a driven gear that meshes with the driving gear. This improves the transmission accuracy and reliability between the driving wheel 210 and the driven wheel 220, which is beneficial for extending the service life of the massage device 1.

[0048] 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 40 more compact.

[0049] 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.

[0050] Optionally, such as Figure 4 As shown, in some embodiments, the first eccentric cam 230 and the driven wheel 220 are integrally formed and fixed. This reduces assembly steps and improves the assembly efficiency of the drive mechanism 40.

[0051] Reference Figure 4 As shown, the thickness direction of the driven wheel 220 is the Z-axis direction. The first drive unit 241 and the first eccentric cam 230 are spaced apart on both sides of the driven wheel 220 in the Z-axis direction, so that the driven wheel 220 can be used to separate the first drive unit 241 and the first eccentric cam 230, thereby further reducing motion interference.

[0052] In combination with any of the above embodiments, such as Figures 2 to 4 As shown, in some embodiments, the first driving member 240 includes a first rotating shaft 242, which includes a transmission body 2421 and a first shaft 2422 rotatably connected to the bearing assembly 100. One end of the transmission body 2421 is fixed to the shaft, and the first driving part 241 is fixed to the other end of the transmission body 2421. The first eccentric cam 230 and the driven wheel 220 are provided with mating holes for fixed transmission engagement with the transmission body 2421. Thus, by providing a first rotating shaft, it is convenient to integrate and install the first eccentric cam 230 and the driven wheel 220 onto the transmission body 2421, and then rotatably connect them to the bearing assembly 100 via the first shaft 2422. This achieves coaxial rotatable connection between the first eccentric cam 230 and the driven wheel 220, which can be rotatably mounted on the bearing assembly 100, making assembly easy and the structure compact.

[0053] It should be noted that there are multiple ways to implement the transmission body and the mating hole, as long as they can achieve a plug-in fit and drive the first eccentric cam and the driven wheel 220 to rotate coaxially. For example, the transmission body can be implemented using non-cylindrical structures such as polygonal prisms, semi-cylinders, and elliptical cylinders.

[0054] like Figures 2 to 4As shown, in some embodiments, the first rotating shaft 242 further includes a second shaft 2423, one end of which is fixedly connected to the other end of the transmission body 2421. The first driving part 241 further includes a second eccentric cam 2411 fixedly and drively connected to the other end of the second shaft 2423. Thus, by setting the second shaft 2423, the second eccentric cam 2411 can be positioned away from the driven wheel 220, thereby driving the first massage member 21 to move eccentrically along the bearing surface direction protruding from the bearing assembly 100 to achieve a kneading effect.

[0055] Optionally, such as Figure 2 as well as Figure 4 As shown, in some embodiments, the second eccentric cam 2411 has an inclined end face 2401 at one end away from the driven wheel 220 for pushing against and driving the first massage component 20 to rotate. Thus, the inclined end face 2401 can abut against the transmission rod of the first massage component 21. When the second eccentric cam 2411 rotates, the inclined end face 2401 alone allows the first massage component 21 to move eccentrically around the axis of the second eccentric cam 2411, achieving double eccentric motion. This improves the ability of the first massage component 21 to better simulate human hand kneading techniques and enhances the massage effect of the massage device 1.

[0056] It should be noted that the power source 10 can be implemented in various ways, as long as it can output rotational power to drive the drive wheel 210 to rotate. For example, the power source 10 includes a motor. In addition, the power source 10 can be directly connected to the drive wheel 210 for transmission, or it can be connected to the drive wheel 210 for transmission through other transmission structures.

[0057] like Figures 2 to 4 As shown, in some embodiments, the transmission assembly 300 includes a worm gear 310 for transmission connection with the power source 10 and a turbine 320 rotatably mounted on the support assembly 100. The worm gear 310 is rotatably mounted on the support assembly 100 and transmissionally engages with the turbine 320. The turbine 320 is fixedly transmissionally connected to the drive wheel 210 to drive the drive wheel 210 to rotate coaxially. Thus, the transmission connection between the power source 10 and the drive wheel 210 is achieved by utilizing the cooperation of the worm gear 310 and the turbine 320, allowing the power source 10 to be flexibly positioned radially on the drive wheel 210, reducing the difficulty of arranging the power source 10.

[0058] In addition, in conjunction with other embodiments, when the massage device 1 has two sets of first massage components 20 and second massage components 30, the power source 10 can use the transmission component 300 to drive the two sets of first massage components 20 and second massage components 30 to move synchronously, further reducing the power source 10 of the massage device 1.

[0059] like Figure 1 as well as Figure 2As shown, the support assembly 100 includes a support member 120 for supporting the drive gear, driven gear, first eccentric cam 230, first drive member 240, second drive member 250, and transmission assembly 300, and a protective shell 130 that cooperates with the support member 120 to protect the drive gear, driven gear, worm gear 310, and turbine 320. This prevents foreign objects from entering the transmission gaps of the drive gear and driven gear, or the transmission gaps of the transmission assembly 300, which could cause damage or jamming. This effectively improves the protective performance of the massage device 1, thereby extending its service life.

[0060] like Figure 1 As shown, the protective shell 130 is provided with a clearance notch 131 to avoid the second drive unit 251. This facilitates the second drive unit 251 to pass through the clearance notch 131 and be connected to the linkage unit of the second massage assembly 30 for transmission, so as to drive the second massage member 31 to move.

[0061] Furthermore, such as Figures 2 to 4 As shown, in some embodiments, the drive assembly 200 further includes a second rotating shaft 260 rotatably connected to the support assembly 100, and the turbine 320 and the drive wheel 210 are fixedly connected to the second rotating shaft 260. This facilitates the integrated mounting of the drive wheel 210 and the turbine 320 onto the second rotating shaft 260, and then the second rotating shaft 260 is rotatably connected to the support assembly 100, enabling the drive wheel 210 and the turbine 320 to be rotatably mounted on the support assembly 100. This design is easy to assemble and has a compact structure.

[0062] It should be noted that the "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 second driving member 250 and the first eccentric cam 230. For example, in some embodiments, the second driving member 250 also includes a transmission ring 252 that is sleeved and engaged with the first eccentric cam 230, and a rod 253 protruding from the transmission ring 252, with the second driving part 251 disposed on the rod 253. In this way, through the transmission ring 252 sleeved and engaged with the first eccentric cam 230, the eccentric driving force of the first eccentric cam 230 can be used to drive the rod 253 to reciprocate, thereby enabling the second driving part 251 to move along the set trajectory.

[0063] Optionally, such as Figure 2 As shown, in some embodiments, the support assembly 100 is provided with a slide groove 110, and the second drive unit 251 includes a first rotating protrusion 2511 fixed to one end of the rod body 253. The first rotating protrusion 2511 is disposed away from the transmission ring 252 and slides in engagement with the slide groove 110. In this way, the first rotating protrusion 2511 can be rotatably connected to the linkage unit of the first massage assembly 20 and slide in engagement with the slide groove 110 to generate a telescopic force that drives the linkage unit to move.

[0064] Optionally, the second massage element 31 can reciprocate relative to the support assembly 100 to achieve kneading massage. In this case, the second massage element 31 can be driven to reciprocate through the linkage unit by the sliding engagement between the first rotating protrusion 2511 and the slide groove 110.

[0065] like Figures 5 to 7 As shown, in other embodiments, the second drive unit 251 includes a ball joint 2512 disposed at one end of the rod 253. The ball joint 2512 is disposed at the end away from the transmission ring 252 and is used to drive the second massage assembly 30 to move. In this way, the ball joint 2512 can be ball-jointed with the linkage unit of the second massage assembly 30, which facilitates the flexible design of the linkage unit according to the driving force required by the second massage member 31.

[0066] Optionally, such as Figure 5 As shown, the second massage member 31 can reciprocate up and down relative to the support assembly 100 to achieve pressing massage. At this time, connected to the linkage unit via the ball joint 2512, the second massage member 31 can be driven to reciprocate up and down.

[0067] like Figure 6 as well as Figure 7 As shown, in some embodiments, the second drive unit 251 includes a first connecting body 2501 with a first groove 2001 and a second connecting body 2502 with a second groove 2002. The first connecting body 2501 is fixedly connected to the rod body 253, and the first connecting body 2501 and the second connecting body 2502 are fixedly connected so that the first groove 2001 and the second groove 2002 cooperate to form a hole-shaped ball joint 2512. Thus, the linkage unit of the second massage assembly 30 is provided with a ball joint 32, which is disposed on the first connecting body 2501 through the first groove 2001. Then, the second connecting body 2502 is fixedly connected to the first connecting body 2501 and cooperates with the ball joint 32 through the second groove 2002, which facilitates the connection between the ball joint 32 and the ball joint 2512 and is easy to assemble.

[0068] like Figure 6 as well as Figure 7As shown, in some embodiments, one of the first connector 2501 and the second connector 2502 is provided with at least two through holes 2003 spaced apart on the outer edge of the ball joint portion 2512, and the other is provided with internally threaded holes 2004 corresponding to the through holes 2003. The drive assembly 200 includes fasteners (not shown) corresponding to the through holes 2003. The fasteners pass through the through holes 2003 and are screwed into the internally threaded holes 2004 to fix the first connector 2501 and the second connector 2502 together. In this way, the fasteners passing through the through holes 2003 and being screwed into the internally threaded holes 2004 to fix the first connector 2501 and the second connector 2502 together make them detachable and easy to assemble and disassemble with the ball joint 32.

[0069] Fasteners include bolts, screws, etc.

[0070] like Figure 5 as well as Figure 6 As shown, in some embodiments, the second drive unit 251 further includes a second rotating protrusion 2513 for driving the third massage assembly 50. The second rotating protrusion 2513 is fixed to the rod body 253 and disposed between the ball joint 2512 and the transmission ring 252. Thus, the second rotating protrusion 2513 can be rotatably connected to the linkage unit of the third massage assembly 50 and can drive the linkage unit to reciprocate.

They are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0072] Furthermore, the terms "first," "second," etc., 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," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0073] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0074] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0075] It should be noted that when a component is referred to as "fixed to," "set on," "fixed to," or "mounted on" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. Furthermore, when a component is considered to be "fixedly connected" to another component, the connection can be detachable or non-detachable, such as through socketing, snap-fitting, integral molding, welding, etc., which are achievable in conventional technologies and will not be elaborated upon here. When a component is perpendicular or approximately perpendicular to another component, it means that the ideal state is perpendicularity, but due to manufacturing and assembly factors, there may be a certain degree of perpendicularity error. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only and do not represent the only possible implementation.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure.
