Description

Technical Field

[0001] This disclosure relates to the field of health care devices, and in particular to a massage device. Background Technology

[0002] Massage devices, used to relieve or eliminate physical fatigue, are becoming increasingly popular due to their flexibility and convenience. To achieve better massage results, targeted massage devices are usually designed based on the structural characteristics of different parts of the body, such as neck massage devices, waist massage devices, and shoulder and neck massage devices.

[0003] In related technologies, some massage devices can use multiple massage components to simultaneously massage two or more parts of the body (such as the shoulders and neck) to improve massage efficiency. However, some massage components in these devices need to follow the movement of other massage components, and their movement trajectories are difficult to design independently, resulting in poor massage effects and hindering the improvement of the overall massage effect of the device. Utility Model Content

[0022] In one embodiment, one of the second limiting body and the first massage member is provided with a second limiting groove, and the other is provided with a limiting protrusion. The limiting protrusion slides in conjunction with the second limiting groove so that the first massage member swings relative to the second massage member.

[0023] In one embodiment, the driving member rotates about a first axis. The driving member includes a first connecting portion and a second connecting portion spaced apart from the first connecting portion along the first axis.

This allows the drive unit to drive both the first and second massage elements to rotate synchronously eccentrically relative to a first axis. Furthermore, the eccentric drive unit can also drive the first massage element to oscillate relative to the second massage element, allowing the movement trajectory between the first and second massage elements to be independently designed according to the curve of the desired massage area. This results in a better fit to the corresponding area for massage, enhancing the massage effect of the device.

Detailed Implementation

[0050] 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.

[0051] 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.

[0052] 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 shoulder and neck massagers. Currently, there are numerous types and brands of massage devices available, offering 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.

[0053] In related technologies, some massage devices can simultaneously massage two or more parts of the body (such as the shoulders and neck) using multiple massage components to improve massage efficiency. However, some massage components in these devices need to move in sync with other components, making it difficult to design their movement trajectories independently. This results in poor massage effects and hinders the overall effectiveness of the massage device. For example, with the increasing prevalence of sedentary work and lifestyles, people are prone to both neck and shoulder discomfort, leading to a growing market demand for neck and shoulder massage devices that can simultaneously massage both the neck and shoulders. Neck and shoulder massage devices are specifically designed for the curves of the shoulders and neck. They use shoulder massage components to massage and relax shoulder muscles, effectively relieving shoulder fatigue. Simultaneously, they use neck massage components to massage and relax neck muscles, effectively relieving shoulder fatigue. However, because the shoulder and neck massage components move synchronously, the movement trajectory of the shoulder massage components is limited by the movement trajectory of the neck massage components, typically only achieving a pinching motion, resulting in less than ideal shoulder massage effects.

[0054] Based on this, the present disclosure provides a massage device in which the massage components can move synchronously and eccentrically and the movement trajectory can be designed independently, so as to effectively massage two or more parts of the human body at the same time and improve the massage effect.

[0055] To better understand the massage device disclosed herein, the following description is provided in conjunction with the accompanying drawings.

[0056] like Figures 1 to 3 As shown, in some embodiments, a massage device 10 is provided, including a support assembly 100, a drive device 200, and a massage assembly 300. The drive device 200 includes a first drive mechanism 210 disposed on the support assembly 100 and a drive member 220 rotatably disposed on the support assembly 100. The first drive mechanism 210 drives the drive member 220 to rotate around a first axis 231, and the drive member 220 is provided with an eccentric drive portion 221. The massage assembly 300 includes a first massage member 310 and a second massage member 320, which are movably connected and drively connected to the eccentric drive portion 221. The second massage member 320 is movably connected to the support assembly 100 and rotatably connected to the drive member 220. The drive member 220 can drive the first massage member 310 and the second massage member 320 to move synchronously eccentrically relative to the first axis 231, and the eccentric drive portion 221 can drive the first massage member 310 to oscillate relative to the second massage member 320.

[0057] The massage device 10 is connected to the first massage element 310 via an eccentric drive unit 221, which mounts the first massage element 310 onto the drive unit 220. The drive unit 220 is then rotatably connected to the second massage element 320, which is also mounted onto the drive unit 220. This allows the drive unit 220 to drive both the first and second massage elements 310 to rotate synchronously eccentrically relative to the first axis 231. Furthermore, the eccentric drive unit 221 can also drive the first massage element 310 to oscillate relative to the second massage element 320, allowing the movement trajectory between the first and second massage elements 310 to be independently designed according to the curve of the desired massage area. This enables better conformity to the corresponding area for massage, enhancing the massage effect of the massage device 10.

[0058] Understandably, the first massage element 310 and the second massage element 320 are movably connected. Compared with the traditional technical solution where the first massage element 310 and the second massage element 320 are fixed together, the motion trajectory design of the first massage element 310 and the second massage element 320 is more flexible and easier to design according to the body parts to be massaged. During this process, when the second massage element 320 massages a second part of the body, the first massage element 310 incorporates eccentric motion, easily achieving a different motion trajectory than the second massage element 320. This allows for massage based on the characteristics of a first part that differs from the second part, enabling the massage device 10 to design different motion trajectories for different parts of the body.

[0059] Furthermore, the drive member 220 can drive the first massage member 310 and the second massage member 320 to rotate synchronously and eccentrically relative to the first axis 231, making it easy for both the first massage member 310 and the second massage member 320 to perform kneading massage.

[0060] It should be noted that "the first drive mechanism 210 is used to drive the drive member 220 to rotate about the first axis 231" includes rotation of the drive member 200 whose rotation axis is not coaxial with the first axis 241 (e.g., Figure 8 As shown), it also includes the rotation axis of the drive member 220 rotating coaxially with the first axis 231 (e.g., Figure 10 or Figure 11 As shown,).

[0061] It should be noted that the first motor mechanism includes devices that directly provide rotational power, such as servo motors and rotary hydraulic cylinders, as well as other devices that indirectly provide rotational power, such as pneumatic rods / hydraulic cylinders / linear motors + gear rack mechanisms, pneumatic rods / hydraulic cylinders / linear motors + crank rocker mechanisms or crank slider 333 mechanisms, servo motors + gearboxes, servo motors + flexible transmission mechanisms, etc., which can drive the rotating shaft 230 to rotate.

[0062] See you later Figure 1 and combined Figure 9 As shown, in some embodiments, the first drive mechanism 210 includes a first motor 211 disposed on the support component 100 and a transmission component 212 that drives the drive member 220 to rotate via the transmission component 212. Thus, the rotation of the rotating shaft 230 is achieved through the cooperation of the first motor 211 and the transmission component 212, allowing for flexible positioning of the first motor 211 and the drive member 220, reducing the design complexity of the massage device 10.

[0063] For example, transmission assembly 212 includes belt drive assembly 212, chain drive assembly 212, gear drive assembly 212, etc.

[0064] like Figure 1 as well as Figure 9 As shown, in some embodiments, the massage components 300 include two sets, symmetrically spaced along a first direction on the support component 100. The first motor 211 drives the two drive members 220 to rotate synchronously via the transmission component 212. Thus, the two sets of massage components 300 can be used to massage the muscles on both sides of the human body (e.g., the muscles on both sides of the shoulders 21 and neck 22), enhancing the massage area of ​​the massage device 10. Furthermore, by enabling the synchronous movement of the two massage components 300 through the first motor 211 and the transmission component 212, the power source can be reduced, lowering the manufacturing cost of the massage device 10.

[0065] Optionally, such as Figure 1 as well as Figure 9 As shown, in some embodiments, the transmission assembly 212 includes a transmission gear 2121 rotatably mounted on the support assembly 100, a first worm gear 2122 coaxially rotatably connected to the transmission gear 2121, and two gear sets 2123 meshing with the transmission gear 2121. The motor includes a first worm 2111 that drives the first worm gear 2122. The two gear sets 2123 correspond one-to-one with the two sets of massage components to drive the two drive members 220 to rotate synchronously. Thus, when the massage device 10 is in use, the first motor 211 outputs power, which drives the first worm gear 2122 to rotate via the first worm gear 2111. This, in turn, drives the two gear sets 2123 to rotate via the transmission gear 2121, and drives the two drive members 220 to rotate synchronously. This, in turn, drives the two massage components 300 to rotate synchronously, thereby achieving massage of the muscles on both sides of the spine and the muscles of the two shoulders 21.

[0066] The gear set 2123 includes at least one gear. In one embodiment, the gear set 2123 includes two gears.

[0067] It should be noted that the massage positions of the first and second massage units can be flexibly set according to actual needs. For example, the first massage unit can be used to massage the shoulders, and the second massage unit can be used to massage the neck. Alternatively, the first massage unit can be used to massage the back, and the second massage unit can be used to massage the shoulders. Or, the first massage unit can be used to massage the waist, and the second massage unit can be used to massage the back. Or, the first massage unit can be used to massage the buttocks, and the second massage unit can be used to massage the waist. Or, the first massage unit can be used to massage the lower thighs, and the second massage unit can be used to massage the lower thighs, and so on.

[0068] To better understand the massage device 10 of this application, it will be described below in conjunction with its application in shoulder and neck massage.

[0069] like Figure 1 as well as Figure 3 As shown, in some embodiments, the first massage element 310 includes a first massage head 311 for contact with the human body. When the drive element 220 drives the first massage element 310 to move eccentrically relative to the first axis 231, the first massage head 311 can knead the shoulder 21 of the human body. Thus, when the massage device 10 is in use, the first massage element 310 abuts against the shoulder 21 of the human body. The first drive mechanism 210 can drive the drive element 220 to rotate, causing the first massage element 310 and the second massage element 320 to move synchronously. During this process, the drive element 220 drives the eccentric drive part 221 to rotate, so that the first massage element 310 combines eccentric movement, and the first massage head 311 can swing relative to the second massage element 320 to simulate the kneading effect of a human hand, thereby achieving kneading massage of the shoulder 21 of the human body and improving the massage effect of the shoulder 21.

[0070] like Figure 1 As shown, in some embodiments, the second massage member 320 includes a second massage head 321 for contact with the human body. When the driving member 220 drives the second massage member 320 to move eccentrically relative to the first axis 231, the second massage head 321 can knead the human neck 22. When the massage device 10 is in use, the second massage head 321 abuts against the human neck 22. The first driving mechanism 210 can drive the driving member 220 to rotate, causing the first massage member 310 and the second massage member 320 to move synchronously, so that the second massage head 321 can swing to knead and massage the human neck 22.

[0071] In conjunction with the above embodiments, the first massage head 311 can perform kneading massage on the human shoulder 21, enabling the massage device 10 to perform kneading massage on the shoulder 21 and neck 22, thereby improving the massage effect of the massage device 10.

[0072] It should be noted that there is no limit to the number of the first massage heads 311, including but not limited to 1, 2, 3, etc., which can be flexibly designed according to actual massage needs.

[0073] It should be noted that there is no limit to the number of the second massage head 321, including but not limited to 1, 2, 3, etc., which can be flexibly designed according to actual massage needs.

[0074] like Figure 1 as well as Figure 3 As shown, in some embodiments, the first massage head 311 is capable of kneading the human shoulder 21 along the first kneading trajectory 301.

[0075] In other embodiments, the first massage head 311 can design a first kneading trajectory based on the curve of the human back to knead the human back. Alternatively, the first massage head 311 can design a first kneading trajectory based on the curve of the human waist to knead the human waist. Alternatively, the first massage head 311 can design a first kneading trajectory based on the curve of the human buttocks to knead the human buttocks. Alternatively, the first massage head 311 can design a first kneading trajectory based on the curve of the human thigh to knead the human thigh.

[0076] It should be noted that the first kneading trajectory 301 can be flexibly designed according to the curve of the body part to be massaged, as long as it can simulate the effect of human hand kneading massage. For example, when using the first massage piece 310 to massage the shoulder 21, the first kneading trajectory 301 includes a first circular curve, which can move from the scapula towards the spine, reach a first set position, and then move towards the neck 22. After reaching a second set position above the first set position, it moves from the spine towards the scapula again. This process is repeated to achieve kneading. Of course, it can also move in the opposite direction, from the spine towards the scapula to the second set position...

[0077] Alternatively, the first kneading trajectory 301 moves from the initial position down (towards the back) along the rhomboid muscles (or other shoulder muscles 21), then towards the spine, then towards the neck 22, and finally back to the initial position. This kneading is repeated. Of course, the movement can also be reversed, moving from the initial position towards the neck 22…

[0078] For example, when using the first massage element 310 to perform a back massage, the first kneading trajectory 301 includes a second circular curve, which can move from the side of the body towards the spine, reach a first preset position, and then move towards the neck 22. After reaching a second preset position above the first preset position, it moves again from the spine towards the side of the body. This kneading is achieved by repeating the process. Of course, the movement can also be reversed.

[0079] Alternatively, the first kneading trajectory 301 moves from the initial position down the latissimus dorsi (or other back muscles) towards the buttocks, then towards the spine, then towards the shoulder 21, and finally back to the initial position. This kneading is repeated. Of course, the movement can also be reversed.

[0080] In some embodiments, the second massage head 321 is capable of kneading the human neck 22 along the second kneading trajectory 302.

[0081] In other embodiments, the second massage head 321 can design a second kneading trajectory based on the shoulder curve of the human body to knead the shoulder area. Alternatively, the second massage head 321 can design a second kneading trajectory based on the back curve of the human body to knead the back area. Alternatively, the second massage head 321 can design a second kneading trajectory based on the waist curve of the human body to knead the waist area. Alternatively, the second massage head 321 can design a second kneading trajectory based on the hip curve of the human body to knead the hips area. Alternatively, the second massage head 321 can design a second kneading trajectory based on the thigh curve of the human body to knead the thighs area.

[0082] It should be noted that the second kneading trajectory 302 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 second massage element 320 to massage the neck 22, the second kneading trajectory 302 includes a first circular curve, which can move from the side of the neck 22 towards the spine, and after reaching a first set position, it moves towards the head. After reaching a second set position above the first set position, it moves from the spine towards the side of the neck 22. This process is repeated to achieve kneading. Of course, the movement can also be reversed.

[0083] Alternatively, the second kneading trajectory 302 moves from the initial position down (towards the back) along the trapezius muscle (or other shoulder and neck muscles), then towards the spine, then towards the neck 22, and finally back to the initial position. This kneading is repeated. Of course, the movement can also be reversed.

[0084] It should be noted that the specific implementation methods of the first kneading trajectory 301 and / or the second kneading trajectory 302 include closed curves, spiral curves, non-closed partially circular curves, etc.

[0085] like Figure 3As shown, the width direction of the neck 22 and the shoulder width direction are in the same direction as the X direction, the length direction of the spine and the length direction of the neck 22 are in the same direction as the Y direction, and the thickness direction of the spine or muscle thickness is in the same direction as the Z direction. In some embodiments, the first kneading trajectory 301 includes a first trajectory 3011 that moves the first massage head 311 closer to the human spine and simultaneously moves the first massage head 311 closer to the second massage head 321, and a second trajectory 3012 that moves the first massage head 311 away from the human spine and simultaneously moves the first massage head 311 away from the second massage head 321. The first trajectory 3011 and the second trajectory 3012 are connected end to end. In this way, when the first massage head 311 moves along the first trajectory 3011, the massage intensity can be gradually increased from the back to the neck 22, and the massage can conform to the curve of the shoulder 21. When the first massage head 311 moves along the second trajectory 3012, it can gradually reduce the massage intensity from the neck 22 towards the back, thereby kneading and massaging the shoulder 21 and improving the massage effect of the shoulder 21.

[0086] Understandably, when the first massage head 311 moves along the first trajectory 3011, the eccentricity of the eccentric rotating part 133 driving the first massage member 310 to move gradually increases as it rotates with the driving member 220. Conversely, when the first massage head 311 moves along the second trajectory 3012, the eccentricity of the eccentric rotating part 133 driving the first massage member 310 to move gradually decreases as it rotates with the driving member 220.

[0087] The shoulder muscles include the levator scapulae, trapezius, and rhomboid muscles, among others. Because the trapezius and levator scapulae muscles have different muscle curves, to better relax the shoulder and neck muscles 22, in some embodiments, when the first massage head 311 moves along the first trajectory 3011, the eccentric drive unit 221 can drive the first massage head 311 of the first massage member 310 to move closer to the second massage head 321, and the second massage head 321 moves towards squeezing the neck 22. Thus, the second massage head 321, in conjunction with the first massage head 311, can pinch and knead the splenius capitis and / or levator scapulae muscles. When the first massage head 311 moves along the second trajectory 3012, the eccentric drive unit 221 can drive the first massage head 311 of the first massage member 310 to move away from the second massage head 321, and the second massage head 321 moves away from the neck 22. In this way, the second massage head 321 and the first massage head 311 release the pinching of the splenius muscles of the head and neck and the levator scapulae muscles, and use the first massage head 311 and the second massage head 321 to achieve kneading and pinching massage of the neck and shoulders 22, thereby improving the massage effect of the massage device 10.

[0088] like Figure 4As shown, in some embodiments, the first massage head 311 protrudes from the support assembly 100 along a first direction, and the second massage head 321 protrudes from the support assembly 100 along a second direction, the first and second directions intersecting. Thus, when the first massage head 311 abuts against the shoulder 21 of the human body, the second massage head 321 can also abut against the neck 22 of the human body, making it easy to wear. Figure 3 As shown, the first direction is in the same direction as the X direction, and the second direction is in the same direction as the Z direction.

[0089] In conjunction with the aforementioned embodiment of the first massage head 311, such as Figure 5 As shown, in some embodiments, the first massage member 310 includes a body 313 that is tractively connected to the eccentric drive unit 221 and a guide body 314 that is slidably connected to the body 313. The first massage head 311 is disposed at the end of the guide body 314. Thus, the slidable connection between the guide body 314 and the body 313 allows the extension length of the first massage head 311 to be adjustable, thereby increasing the massage range and flexibly adjusting according to the user's desired massage location. For example, when it is necessary to massage the trapezius muscle near the neck 22, the guide body 314 retracts into the body 313, shortening the first massage head 311 to massage the trapezius muscle. Conversely, when it is necessary to massage the rhomboid muscle away from the neck 22, the guide body 314 extends into the body 313, lengthening the first massage head 311 to massage the rhomboid muscle.

[0090] Of course, the extension length of the first massage head 311 can also be adjusted according to the different massage needs of the shoulder muscles 21. For example, the extension length of the first massage head 311 can be adjusted to different massage positions on the trapezius or rhomboid muscles.

[0091] like Figure 5 As shown, in some embodiments, the massage assembly 300 further includes a telescopic drive unit 330, which drives the guide body 314 to reciprocate relative to the body 313. Thus, the position between the guide body 314 and the body 313 can be electrically adjusted using the telescopic drive unit 330, thereby making the extension length of the first massage head 311 adjustable.

[0092] The telescopic drive unit 330 can be implemented in various ways, including but not limited to power devices that directly drive the guide body 314 such as pneumatic rods, hydraulic rods, and linear motors, as well as telescopic mechanisms that indirectly realize the telescopic movement of the guide body 314 such as gear and rack mechanisms and screw and nut mechanisms.

[0093] like Figure 5As shown, in some embodiments, the telescopic drive unit 330 includes a drive motor 331 disposed on the body 313, a screw rotatably disposed on the body 313, and a slider 333 fixedly connected to the guide body 314. The slider 333 is threadedly connected to the screw. The drive motor 331 can drive the screw to rotate, thereby causing the slider 333 to move along the axis of the screw, and thus causing the guide body 314 to move relative to the body 313, thereby adjusting the extension length of the first massage head 311. This embodiment is easy to implement and has a compact structure.

[0094] It should be noted that the second massage component 320 can be movably connected to the support component 100 in various ways, such as sliding connection, rotational connection, and rotation + sliding, etc.

[0095] like Figure 6 As shown, in some embodiments, the supporting component 100 is provided with a first limiting groove 131, and the second massage member 320 includes a first limiting body 322 and a mating body 323 rotatably connected to the driving member 220. The first limiting body 322 is provided with a first limiting portion 3221 that limits and engages with the first limiting groove 131. The first limiting portion 3221 is at least partially spherical and can rotate and slide within the first limiting groove 131. Thus, during the movement of the second massage member 320 driven by the driving member 220, the first limiting portion 3221 rotates within the second limiting groove 3241 and can slide within the first limiting groove 131, allowing the second massage member 320 to move along the second kneading trajectory 302. Furthermore, through the movable connection and eccentric movement between the first massage member 310 and the second massage member 320, the second massage member 320 can restrict the first massage member 310 from moving along the first kneading trajectory 301.

[0096] In other embodiments, the first limiting body 322 is rotatably connected to the mating body 323, and the first limiting part 3221 is ball-jointed with the first limiting groove 131. This also allows the second massage head 321 to move along the second kneading trajectory 302.

[0097] Furthermore, such as Figure 6 As shown, in some embodiments, the second massage member 320 further includes a second limiting body 324 disposed on the other side of the mating body 323 and opposite to the first limiting body 322, and the second limiting body 324 is slidably connected to the first massage member 310. Thus, by slidingly connecting the second limiting body 324 to the first massage member 310, the first massage member 310 can swing with the second massage member 320 under the drive of the driving member 220 and can slide relative to the second massage member 320, making the distance between the first massage head 311 and the second massage head 321 adjustable, and enabling the first massage head 311 to move along the first kneading trajectory 301.

[0098] It should be noted that there are various ways to achieve the sliding connection between the second limiting body 324 and the first massage component 310, including but not limited to the cooperation of the slide rail and the slider 333. Alternatively, as... Figure 6 as well as Figure 8 As shown in one example, one of the second limiting body 324 and the first massage member 310 is provided with a second limiting groove 3241, and the other is provided with a limiting protrusion 312. The limiting protrusion 312 and the second limiting groove 3241 are slidably engaged so that the first massage head 311 swings relative to the second massage member 320.

[0099] Optionally, in some embodiments, the drive member 220 rotates around the first axis 231, the length direction of the first limiting groove 131 is aligned with the direction of the first axis 231, and the depth of the first limiting groove 131 gradually increases along the first axis 231 and toward the eccentric drive part 221. Thus, even if the second kneading trajectory 302 is adjusted, the first limiting groove 131 can still engage with the first limiting part 3221 to meet the adjustment requirements of the second kneading trajectory 302.

[0100] For example, the swing angle of the drive component 220 changes, causing the second kneading trajectory 302 to change, so as to meet the user's different massage intensity and the massage needs of different specific locations of the same part.

[0101] like Figure 8 , Figure 10 as well as Figure 11 As shown, in some embodiments, the drive member 220 rotates about a first axis 231. The drive member 220 includes a first connecting portion 222 and a second connecting portion 223 spaced apart from the first connecting portion 222 along the direction of the first axis 231. The first connecting portion 222 and the second connecting portion 223 are not coaxial with the first axis 231. The eccentric drive portion 221 is fixed to the first connecting portion 222, and the second massage member 320 is rotatably connected to the second connecting portion 223. In this way, the first massage member 310 and the second massage member 320 can be modularly assembled onto the drive member 220. Since the first connecting portion 222 and the second connecting portion 223 are not coaxial with the first axis 231, the first massage member 310 and the second massage member 320 can rotate about the first axis 231, but are not coaxial with the first axis 231. Therefore, when the drive member 220 rotates, it can drive the first massage member 310 to move along the first kneading trajectory 301 and drive the second massage member 320 to move along the second kneading trajectory 302.

[0102] In accordance with the aforementioned needs for shoulder and neck massage, the first axis 231 is set in the same direction as the width direction of the human neck 22.

[0103] See you later Figure 2 and combined Figure 8As shown, in some embodiments, the driving device 200 further includes a rotating shaft 230 rotatably disposed on the supporting component 100. The rotation axis 230 line of the rotating shaft 230 is coaxially disposed with the first axis 231. The driving member 220 is drivenly connected to the rotating shaft 230, and a third obtuse angle is formed between the driving member 220 and the rotating shaft 230. The first driving mechanism 210 drives the driving member 220 to rotate via the rotating shaft 230. In this way, the first massage member 310 and the second massage member 320 can be modularly assembled onto the driving member 220, and then drivenly connected to the rotating shaft 230. The third obtuse angle between the driving member 220 and the rotating shaft 230 makes the driving member 220 non-coaxial with the first axis 231. This enables the first massage member 310 and the second massage member 320 to rotate around the first axis 231, but they are not coaxial with the first axis 231. It is convenient to use the drive component 220 to drive the first massage component 310 to move along the first kneading trajectory 301 and to drive the second massage component 320 to move along the second kneading trajectory 302.

[0104] In conjunction with the aforementioned embodiment of gear set 2123, the rotating shaft 230 is connected to the gear set 2123 in a transmission connection so that the first motor 211 can drive the rotating shaft 230 to rotate.

[0105] See you later Figure 2 and combined Figure 8 As shown, in some embodiments, the drive member 220 includes a drive rod 225 and an eccentric cam 224. The drive rod 225 has a first connecting portion 222 and a second connecting portion 223. The eccentric cam 224 is fixedly connected to the first connecting portion 222 and has an eccentric drive portion 221. Thus, by fixing the eccentric cam 224 to the drive rod 225 to form the drive member 220, the manufacturing difficulty of the drive member 220 can be reduced.

[0106] It should be noted that there are various ways to fix the drive rod 225 and the eccentric cam 224, including but not limited to snap-fit ​​fixing, screw fixing, riveting fixing, pin fixing, welding fixing, etc.

[0107] See you later Figure 2 and combined Figure 8As shown, in some embodiments, the eccentric cam 224 is further provided with a protrusion 2241 adjacent to the eccentric drive unit 221. The drive member 220 also includes a limiting ring 226 fixedly connected to the eccentric cam 224. The limiting ring 226 and the protrusion 2241 are spaced apart to form a limiting structure that restricts the movement of the first massage member 310 along the axial direction of the eccentric cam 224. Thus, when the first massage member 310 is assembled with the eccentric cam 224, the first massage member 310 is mounted on the eccentric drive and limited by the protrusion 2241. Then, the limiting ring 226 is fixed to the eccentric cam 224 to form a limiting structure that restricts the movement of the first massage member 310 along the axial direction of the eccentric cam 224.

[0108] In some embodiments, the first massage member 310 is provided with a relief groove 315 to avoid the protrusion 2241. In this way, by providing the relief groove 315, the protrusion 2241 can be avoided, and the two will not interfere with each other.

[0109] It should be noted that there are various ways in which the drive rod 225 and the second massage element 320 can be rotatably connected, including but not limited to bearing connection, bushing connection, etc.

[0110] And such Figure 8 As shown, the third obtuse angle is c. Optionally, the third obtuse angle includes any one of 95° to 175°. Specifically, it includes 100°, 110°, 120°, 130°, 140°, 150°, etc.

[0111] like Figure 8 As shown, in some embodiments, the size of the third obtuse angle is adjustable. Thus, by adjusting the size of the third obtuse angle, the first kneading trajectory 301 can be adjusted to regulate the massage range of the first massage element 310 and the massage intensity on the shoulder 21. Simultaneously, the second kneading trajectory 302 can also be adjusted to regulate the massage range and intensity of the second massage element 320.

[0112] Optionally, the third obtuse angle can be adjusted within the range of 95° to 175°, 100° to 160°, 120° to 150°, etc.

[0113] Understandably, considering the aforementioned needs for shoulder and neck massage, the closer the shoulder 21 is to the spine, the more concave it will be, while the further away from the spine, the more convex it will be. For example, when the neck 22 requires greater massage pressure, and / or when the shoulder 21 is in an uncomfortable position close to the spine, increasing the third obtuse angle allows the first massage head 311 to cover a larger area, generating greater kneading massage pressure on the shoulder 21. Furthermore, the first massage head 311 has a greater range of motion to massage the uncomfortable areas close to the spine.

[0114] For example, when the neck 22 requires a smaller massage intensity, and / or the shoulder 21 is in an uncomfortable position on a raised area, reducing the size of the third obtuse angle decreases the massage range and intensity of the second massage head 321. The second massage head 321 will then knead away from the raised area along the spine, resulting in a more concentrated massage area and better massage effect in that region.

[0115] It should be noted that there are several ways to make the third obtuse angle between the driving component 220 and the rotating shaft 230 adjustable. For example, the driving component 220 and the rotating shaft 230 are rotatably connected and equipped with a locking structure. When the locking structure is released, the third obtuse angle can be adjusted. When the locking structure is tightened, the third obtuse angle is fixed.

[0116] For example, the drive unit 220 is rotatably connected to the rotating shaft 230, and the size of the third obtuse angle is adjusted by the connecting rod 240 assembly.

[0117] like Figure 1 , Figure 7 as well as Figure 8 As shown, in some embodiments, the support assembly 100 includes a support frame 110, a first mounting member 120, and a second mounting member 130 spaced apart from the first mounting member 120 along a first axis 231 on the support frame 110. A rotating shaft 230 is rotatably mounted on the first mounting member 120. A first massage member 310 is disposed close to the first mounting member 120, and a second massage member 320 is disposed close to the second mounting member 130 and movably connected to the second mounting member 130. The drive device 200 also includes a connecting rod 240, one end of which is rotatably connected to the second mounting member 130, and the other end of which is drively connected to one end of the drive member 220. Thus, the first mounting member 120 and the second mounting member 130 facilitate the integration of the connecting rod 240, the rotating shaft 230 of the drive member 220, and the massage assembly 300 together, and then modularly mounted onto the support assembly 100. By connecting the drive component 220 and the second mounting component 130 together through the connecting rod 240, the force on the drive component 220 is more stable and less prone to damage, thereby improving the reliability of the massage device 10.

[0118] In conjunction with the aforementioned embodiment of gear set 2123, gear set 2123 is rotatably mounted on the first mounting member 120.

[0119] In conjunction with the aforementioned embodiment of the first limiting groove 131, the first limiting groove 131 is disposed on the second mounting member 130.

[0120] Optionally, the first mounting member 120 mates with the gear set 2123 to form a gearbox. This facilitates gear lubrication and improves the durability of the massage device 10.

[0121] like Figure 8As shown, in some embodiments, one end of the connecting rod 240 is rotatably connected to the second mounting member 130, and the other end of the connecting rod 240 is rotatably connected to one end of the driving member 220. The other end of the driving member 220 is rotatably connected to the rotating shaft 230, and the line of rotation of the driving member 220 relative to the rotating shaft 230 is not coaxial with the first axis 231. At least one of the first mounting member 120 and the second mounting member 130 is slidably connected to the support frame 110 so that the distance between the first mounting member 120 and the second mounting member 130 is adjustable. Thus, by adjusting the distance between the first mounting member 120 and the second mounting member 130, the connecting rod 240 and the driving member 220 are driven to rotate, so that the size of the third obtuse angle between the driving member 220 and the rotating shaft 230 can be adjusted, so as to adjust the massage range of the first massage member 310 and the massage intensity on the neck 22. At the same time, the massage range and massage intensity of the second massage member 320 can also be adjusted.

[0122] like Figure 8 As shown, optionally, in some embodiments, the second mounting member 130 includes a mounting body 132 and a rotating part 133 rotatably disposed on the mounting body 132. The connecting rod 240 is rotatably connected to the rotating part 133, and the rotation axis 230 of the rotating part 133 is coaxially arranged with the first axis 231. Thus, the rotating part 133 facilitates the rotatable connection between the connecting rod 240 and the second mounting member 130 without interfering with the angle adjustment of the connecting rod 240 to accommodate the adjustment requirements of the third obtuse angle. Furthermore, since the rotation axis 230 of the rotating part 133 is coaxially arranged with the first rotation axis 231, the rotation of the driving member 220 is more stable, reducing wear and improving durability.

[0123] In some embodiments, the drive device 200 further includes a second drive mechanism 250, which is disposed on the support frame 110. The second drive mechanism 250 is used to drive at least one of the first mounting member 120 and the second mounting member 130 to slide. Thus, the second drive mechanism 250 facilitates adjustment of the distance between the first mounting member 120 and the second mounting member 130, allowing adjustment of the third obtuse angle between the drive member 220 and the rotation shaft 230.

[0124] It should be noted that the second drive mechanism 250 can be implemented in various ways, including but not limited to power devices such as pneumatic rods, hydraulic rods, and linear motors that directly drive the first mounting component 120 and / or the second mounting component 130 to move, as well as telescopic mechanisms such as gear and rack mechanisms and lead screw and nut mechanisms that indirectly realize the telescopic movement of the first mounting component 120 and / or the second mounting component 130.

[0125] like Figures 7 to 9As shown, in some embodiments, the second drive mechanism 250 further includes a first screw 252 rotatably mounted on the support frame 110 and a second motor 251 mounted on the support frame 110, the second motor 251 being capable of driving the first screw 252 to rotate. At least one of the first mounting member 120 and the second mounting member 130 is slidably connected to the support frame 110 and threadedly connected to the first screw 252. Thus, when the first mounting member 120 is slidably connected to the support frame 110 and threadedly connected to the first screw 252, the first mounting member 120 can be moved by manually or electrically rotating the first screw 252 to adjust the distance between the first mounting member 120 and the second mounting member 130. Furthermore, the movement of the first mounting member 120 is achieved through threaded transmission, which easily utilizes the self-locking characteristic of the thread to achieve immediate rotation and stopping of the first mounting member 120.

[0126] And / or, when the second mounting member 130 is slidably connected to the support frame 110 and threadedly connected to the first screw 252, the second mounting member 130 can be moved by manually or electrically rotating the first screw 252 to adjust the distance between the two mounting members 130. Furthermore, the movement of the second mounting member 130 is achieved through threaded transmission, which easily utilizes the self-locking characteristic of the thread to achieve immediate rotation and stopping of the second mounting member 130.

[0127] In conjunction with the aforementioned embodiment of the second drive mechanism 250, the second drive mechanism 250 is disposed on the support frame 110 and is used to drive the first screw 252 to rotate. Thus, the first screw 252 can be driven to rotate electrically, achieving automatic adjustment of the third obtuse angle.

[0128] like Figure 9 As shown, in some embodiments, the second drive mechanism 250 further includes a second worm gear 253 rotatably mounted on the support frame 110, and the second motor 251 is provided with a second worm 2511 that drives the second worm gear 253. The second worm gear 253 is coaxially rotatably connected to the first screw 252. Thus, when it is necessary to adjust the size of the third obtuse angle, the second motor 251 outputs power, which drives the second worm gear 253 to rotate through the second worm 2511, thereby driving the first screw 252 to rotate synchronously on the same axis, realizing the adjustment of the distance between the first mounting member 120 and the second mounting member 130, so as to complete the automatic adjustment of the third obtuse angle.

[0129] Optionally, such as Figure 8As shown, in some embodiments, the first mounting member 120 and the second mounting member 130 are slidably connected to the support frame 110, and the first screw 252 includes a first threaded body 2521 threadedly connected to the first mounting member 120 and a second threaded body 2522 threadedly connected to the second mounting member 130, with the threads of the first threaded body 2521 and the second threaded body 2522 having opposite directions of rotation. Thus, when the first screw 252 rotates, because the threads of the first threaded body 2521 and the second threaded body 2522 have opposite directions of rotation, they can synchronously drive the first mounting member 120 and the second mounting member 130 to move towards or away from each other, thereby adjusting the distance between them quickly.

[0130] Optionally, such as Figure 8 As shown, in some embodiments, the first mounting member 120 and the second mounting member 130 are slidably connected to the support frame 110, respectively. The first screw 252 includes a first threaded body 2521 threadedly connected to the first mounting member 120 and a second threaded body 2522 threadedly connected to the second mounting member 130. The first threaded body 2521 and the second threaded body 2522 have the same thread direction but different pitches. Thus, when the first screw 252 rotates, due to the different pitches of the first threaded body 2521 and the second threaded body 2522, they can synchronously drive the first mounting member 120 and the second mounting member 130 to move towards each other or away from each other, thereby adjusting the distance between them.

[0131] The ratio of the pitch of the first screw 252 body to the pitch of the second threaded body 2522 is 3:1 to 1:3, or 1:1.1 to 1:3, etc.

[0132] In one example, the ratio of the pitch of the first screw 252 body to the pitch of the second threaded body 2522 is 1:1.2, or 1:1.3, or 1:1.4, etc.

[0133] In the aforementioned embodiment of the transmission gear 2121, the first mounting member 120 is slidably connected to the support frame 110, and the sliding direction of the first mounting member 120 is aligned with the axial direction of the transmission gear 2121. The length of the transmission teeth of the transmission gear 2121 is greater than the sliding distance of the first mounting member 120. Thus, even if the first mounting member 120 moves, the gear set 2123 can still mesh with the transmission gear 2121 to drive the rotating shaft 230 to rotate.

[0134] In conjunction with the aforementioned embodiments of the two sets of massage components, the threads of the first threaded bodies 2521 of the two first screws 252 have opposite directions of rotation, and the threads of the second threaded bodies 2522 of the two first screws 252 have opposite directions of rotation. The second drive mechanism 250 can drive the first screws 252 of the two sets of massage components to rotate synchronously. Thus, the second drive mechanism 250 can drive the rotating shafts 230 of the two first screws 252 to rotate synchronously, reducing the power source and lowering the manufacturing cost of the massage device 10.

[0135] In conjunction with the aforementioned embodiment of the second worm gear 253, the second worm gear 253 is coaxially rotatably connected to the first screw 252 of the two sets of massage components.

[0136] In other embodiments, the first mounting member 120 is fixed to the support frame 110, the second mounting member 130 is slidably connected to the support frame 110, and the first screw 252 is threadedly connected to the second mounting member 130. In this way, the distance between the first mounting member 120 and the second mounting member 130 can also be adjusted, and the first mounting member 120 is fixed, which can reduce the design difficulty of the first drive mechanism 210.

[0137] like Figure 8 As shown, in some embodiments, the second mounting member 130 includes a mounting body 132 and a rotating part 133 rotatably disposed on the mounting body 132. The connecting rod 240 is connected to the rotating part 133 in a transmission manner, and the rotation axis 230 of the rotating part 133 is coaxially arranged with the second rotation axis 230. Thus, the rotating part 133 facilitates the rotational connection between the connecting rod 240 and the second mounting member 130. Furthermore, since the rotation axis 230 of the rotating part 133 is coaxial with the second rotation axis 230, the rotation of the driving member 220 is more stable, reducing wear and improving durability.

[0138] In other embodiments, the other end of the connecting rod 240 is fixedly connected to one end of the driving member 220, and the other end of the driving member 220 is fixedly connected to the rotating shaft 230. Thus, the connecting rod 240 connects the driving member 220, the first mounting member 120, the second mounting member 130, and the rotating shaft 230 into a single unit, achieving non-coaxial synchronous rotation of the driving member 220 and the rotating shaft 230.

[0139] Optionally, the connecting rod 240, the drive component 220, and the rotating shaft 230 are integrally formed.

[0140] like Figure 10 as well as Figure 11As shown, in some embodiments, the driving component 220 is a crankshaft 201 that is connected to the first driving mechanism 210. The rotation axis 230 of the crankshaft 201 is coaxial with the first axis 231. The first connecting part 222 is the journal of the first connecting rod 240 of the crankshaft 201, and the second connecting part 223 is the journal of the second connecting rod 240 of the crankshaft 201. The eccentric driving part 221 includes an eccentric cam 224 and is fixed to the journal of the first connecting rod 240. The second massage component 320 is rotatably connected to the journal of the second connecting rod 240. In this way, by using the crankshaft 201 to mount the first massage component 310 and the second massage component 320, it is convenient to realize that the first massage component 310 and the second massage component 320 can rotate around the first axis 231, but are not coaxial with the first axis 231.

[0141] In conjunction with the aforementioned embodiment of gear set 2123, crankshaft 201 is connected to gear set 2123 in a transmission connection so that first motor 211 can drive crankshaft 201 to rotate.

[0142] like Figure 10 as well as Figure 11 As shown, in some embodiments, the minimum distance between the journal of the first connecting rod 240 and the first axis 231 is L1, and the minimum distance between the journal of the second connecting rod 240 and the first axis is L2. Wherein, L1 > L2. This makes the first kneading trajectory 301 and the second kneading trajectory 302 different, so as to achieve kneading for different parts.

[0143] like Figure 10 as well as Figure 11 As shown, in some embodiments, there is a first obtuse angle between the journal of the first connecting rod 240 and the first axis 231. This obtuse angle between the journal of the first connecting rod 240 and the first axis 231 allows the design of the first kneading trajectory 301 to be adjusted according to the size of the first obtuse angle to meet the massage needs of different parts of the body. Figure 10 as well as Figure 11 As shown, the first obtuse angle is α.

[0144] Optionally, the first obtuse angle includes any one of 95° to 175°. Specifically, it includes 100°, 110°, 120°, 130°, 140°, 150°, etc.

[0145] like Figure 10 as well as Figure 11 As shown, in some embodiments, the journal of the second connecting rod 240 has a second obtuse angle with the first axis. Thus, the obtuse angle between the journal of the second connecting rod 240 and the first axis 231 allows the design of the second kneading trajectory 302 to be adjusted according to different sizes of the second obtuse angle to meet the massage needs of different parts of the body. And as... Figure 10 as well as Figure 11 As shown, the second obtuse angle is b.

[0146] Optionally, the second obtuse angle includes any one of 95° to 175°. Specifically, it includes 100°, 110°, 120°, 130°, 140°, 150°, etc.

[0147] It should be noted that the "protrusion" can be "a part of the eccentric cam," meaning the "protrusion" is integrally formed with "other parts of the eccentric cam, such as the eccentric drive unit"; or it can be a separate component that can be separated from "other parts of the eccentric cam, such as the eccentric drive unit," meaning the "protrusion" can be manufactured independently and then combined with "other parts of the eccentric cam, such as the eccentric drive unit" to form a whole. The expressions "a certain body" and "a certain part" in this disclosure are merely one embodiment for ease of reading and are not intended to limit the scope of protection of this disclosure. Any solution that includes the above features and has the same function should be understood as an equivalent technical solution of this disclosure.

[0148] It should be noted that the "first screw" can be one of the parts of the "second drive mechanism" module, that is, it can be assembled into a module with the "other components of the second drive mechanism" and then modularly assembled; or it can be relatively independent from the "other components of the second drive mechanism" and can be installed separately, thus forming a whole with the "other components of the second drive mechanism" in this device.

[0149] Similarly, the components included in the "components," "parts," and "mechanisms" of this disclosure can also be flexibly combined. They can be modularly produced according to actual needs and assembled as an independent module; or they can be assembled separately to form a module in this device. The division of the above-mentioned components in this disclosure is only one embodiment for ease of reading and is not intended to limit the scope of protection of this disclosure. Any technical solution that includes the above-mentioned components and has the same function should be understood as an equivalent technical solution of this disclosure.

[0150] When one component is considered to be "transmission connection" to another component, the two can be fixed in a detachable or non-detachable manner, as long as power transmission can be achieved. Methods such as socketing, snap-fitting, integral molding, and welding can be achieved in traditional technologies, and will not be elaborated here.

[0151] 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.

[0152] 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.
