DETAILED DESCRIPTION

[0055] In order to make the purpose, technical solution and advantages of the present disclosure more clear, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0057] As a health care tool to relieve or eliminate physical fatigue, massage equipment is becoming more and more popular due to its flexible and convenient use. In order to obtain better massage effects, targeted massage equipment is usually designed according to the structural characteristics of various parts of the human body, such as neck massage equipment, waist massage equipment, massage equipment, etc. At present, there are many types and brands of massage equipment, which makes it possible for consumers to choose a lot of massage equipment. How to win the favor of consumers and improve product competitiveness has become an issue that massage equipment manufacturers pay more and more attention to.

[0058] As a health care tool to relieve or eliminate physical fatigue, massage equipment is becoming more and more popular due to its flexible and convenient use. In order to obtain better massage effects, targeted massage equipment is usually designed according to the structural characteristics of various parts of the human body, such as neck massage equipment, waist massage equipment, massage equipment, etc. At present, there are many types and brands of massage equipment, which makes it possible for consumers to choose a lot of massage equipment. How to win the favor of consumers and improve product competitiveness has become an issue that massage equipment manufacturers pay more and more attention to.

[0059] At present, as people are more and more sedentary in work and life, they are prone to muscle discomfort, which makes the market demand for massage equipment that can achieve muscle massage increasingly large. For example, shoulder and neck massage equipment is a massage equipment specially designed for shoulder curves and neck curves. It can use shoulder massage pieces to massage shoulder muscles to relax them and effectively relieve shoulder muscle fatigue. At the same time, it can use neck massage pieces to massage neck muscles to relax them and effectively relieve neck muscle fatigue.

[0060] In the related art, some massage devices can achieve muscle massage, but when the massage parts of such massage devices are damaged or worn, the transmission device needs to be disassembled to complete the replacement of the massage parts, resulting in high maintenance costs.

[0061] Based on this, the present disclosure provides a transmission device, which can be detachably connected to a massage member and can drive the massage member to knead human muscles, thereby making the massage device using the transmission device have a good massage effect and low maintenance cost.

[0062] In order to better understand the transmission device of the present invention, it is described below using a massage device to which the transmission device is applied.

[0063] like Figure 1 As shown, in some embodiments, a massage device 10 is provided, including a bearing assembly 100 , a first driving mechanism 200 , a transmission device 300 , and a first massage member 400 .

[0064] Further combined with Figure 2 As shown, the transmission device includes a mounting assembly 310, a first transmission assembly 320 and a connecting assembly 330. The mounting assembly 310 is fixedly connected to the bearing assembly 100, so that the transmission device 300 is arranged on the bearing assembly 100. The first transmission assembly 320 includes a rotating shaft 321 rotatably arranged on the mounting assembly 310 and a driving member 322 connected to the rotating shaft 321. The driving member 322 can rotate with the rotating shaft 321, and there is a first yoke between the driving member 322 and the rotating shaft 321. The driving member 322 is provided with an eccentric driving portion 3221 and a first connecting portion 3222 spaced apart from the eccentric driving portion 3221 along the direction of the driving member 322. The connecting assembly 330 includes a 331 connected to the eccentric driving part 3221 in a transmission manner and a stopper 332 connected to the second connecting part first connecting member 3311 in a rotational manner. The first connecting member 331 is movably connected to the stopper 332. The first connecting member 331 is provided with a second connecting part first connecting member 3311 for detachably connecting to the first massage member 400. The stopper 332 is movably connected to the mounting assembly 310. The first driving mechanism 200 is provided on the bearing assembly 100 for driving the rotating shaft 321 to rotate.

[0065] Combination Figures 1 to 4As shown, the transmission device 300 is connected to the first connecting member 331 through the eccentric driving part 3221, and the first connecting member 331 is installed on the driving member 322. Then, the first connecting member 3222 is connected to the limiting member 332 through the first connecting member 3222, and the limiting member 332 is also installed on the driving member 322, so that the driving member 322 can drive the first connecting member 331 and the limiting member 332 to rotate synchronously. When the massage device 10 is used, the first massage member 400 is installed on the first connecting member 331 through the second connecting part first connecting member 3311, so that the first massage member 400 is against the part of the human body that needs to be massaged. At this time, the first driving mechanism 200 can drive the rotating shaft 321 to rotate, and the driving member 322 connected to the rotating shaft 321 drives the first connecting member 331 and the limiting member 332 to move synchronously. During the movement of the first connecting member 331, the driving member 322 drives the eccentric driving part 3221 to rotate, so that the first massage member 400 also performs eccentric movement during the swinging movement along with the limiting member 332, and thus the first massage member 400 can simulate the kneading trajectory of a human hand to achieve kneading massage of the part, thereby improving the massage effect of the massage device 10. When the first massage member 400 is damaged or worn, the transmission device 300 does not need to be disassembled, and the first massage member 400 can be replaced by using the second connecting member 3311, thereby improving maintenance efficiency and reducing maintenance costs.

[0066] It should be noted that "there is a first obtuse angle between the driving member and the rotating shaft" includes that the axis of the rotating shaft forms a first obtuse angle with the length direction of the driving member, or the axis of the rotating shaft forms a first obtuse angle with the axis of the driving member, etc. That is, the driving member can rotate around the axis of the rotating shaft and drive the connecting assembly to make an eccentric motion relative to the rotating shaft.

[0067] like Figure 1 as well as Figure 3 As shown, in some embodiments, the first massage member 400 includes a first massage head 410, and the first massage member 400 can at least knead the human body under the drive of the driving member 322. In this way, when the massage device 10 is used, the first massage head 410 is against the human body. The first driving mechanism 200 can drive the rotating shaft 321 to rotate, and the driving member 322 connected to the rotating shaft 321 drives the first connecting member 331 and the limiting member 332 to move synchronously, so as to use the first massage head 410 to massage the human muscles. While the first massage head 410 is massaging the human muscles, the driving member 322 drives the eccentric driving part 3221 to rotate, so that the first massage head 410 also combines the eccentric movement during the swinging movement of the limiting member 332, and then the first massage head 410 can simulate the kneading trajectory of human hands, realize the kneading massage of human muscles, and improve the massage effect of the shoulder 21.

[0068] In one example, combining Figure 3 As shown, the massage device 10 is applied to shoulder and neck massage, and the first massage head 410 is against the human shoulder 21. The first driving mechanism 200 can drive the rotating shaft 321 to rotate, and the driving member 322 connected to the rotating shaft 321 drives the first connecting member 331 and the limiting member 332 to move synchronously, so that the first massage head 410 can massage the human shoulder 21. During the massage of the human shoulder 21 by the first massage head 410, the driving member 322 drives the eccentric driving part 3221 to rotate, so that the first connecting member 331 also performs eccentric movement during the swinging movement, and then the first massage head 410 can simulate the trajectory of kneading the shoulder 21 by human hands, realize kneading and massaging the human shoulder 21, and improve the massage effect of the shoulder 21.

[0069] In some embodiments, the stopper 332 is limitedly matched with the mounting assembly 310 so that the stopper 332 moves along a set first curve. The first connecting member 331 is slidably connected with the stopper 332 so that the second connecting portion 3311 moves along a set second curve. In this way, the second curve is different from the first curve, so that the motion trajectory of the first massage member 400 can be independently designed according to the curve of the desired massage part, and thus can better fit the corresponding part for massage, thereby improving the massage effect of the massage device.

[0070] It should be noted that the "limiting cooperation" between the limiter 332 and the mounting assembly 310 should be understood in a broad sense, and the two can move relative to each other, but the movement trajectory is limited by the other. Specifically, the limiter 332 can move relative to the mounting assembly 310, but the movement trajectory of the limiter 332 is limited by the mounting assembly 310. Specifically, the limiter 332 is slidably connected to the mounting assembly 310 and can rotate relative to the mounting assembly 310.

[0071] like Figure 3 as well as Figure 4 As shown, in some embodiments, the first massage member 410 can rotate with the first connecting member 331, and the eccentric driving part 3221 drives the first massage member 410 to swing relative to the limit member 332, so that the first massage head 3311 reciprocates along the third curve 301 to knead the human body muscles. In this way, during the reciprocating motion of the first massage head 3311 along the third curve 301, the first massage head 3311 can gradually increase the massage intensity, and then gradually reduce the massage intensity, so as to achieve kneading massage of the human body muscles and improve the massage effect.

[0072] Reference Figure 3As shown, when the massage device massages the human shoulder, during the reciprocating motion of the first massage head 3311 along the third curve 301, the first massage head 3311 can gradually increase the massage intensity from the back toward the neck 22, and then gradually reduce the massage intensity from the neck 22 toward the back, thereby achieving kneading massage of the human muscles and improving the massage effect.

[0073] It should be noted that the design of the third curve can be flexibly designed according to the characteristics of the human body curve, and its specific implementation methods include curves, spiral curves, non-closed partial annular curves, etc. For example, the first massage head can knead the shoulders of the human body along the third curve. Alternatively, the first massage head can design the third curve according to the back curve of the human body to knead the back of the human body. Alternatively, the first massage head can design the third curve according to the waist curve of the human body to knead the waist of the human body. Alternatively, the first massage head can design the third curve according to the hip curve of the human body to knead the buttocks of the human body. Alternatively, the first massage head can design the third curve according to the thigh curve of the human body to knead the thigh of the human body.

[0074] It should be noted that the third curve can be flexibly designed according to the curve of the part of the human body that needs to be massaged, as long as it can simulate the kneading massage effect of human hands. For example, when using the first massage piece to perform shoulder massage, the third curve includes a first annular curve, which can move from the shoulder blade to the spine, and after reaching the first set position, move toward the neck. After reaching the second set position set above the first set position, it moves from the spine to the shoulder blade. Kneading is achieved in this reciprocating manner. Of course, it can also move in the opposite direction, from the spine to the shoulder blade to the second set position...

[0075] Alternatively, the third curve moves from the initial position along the rhomboid muscle (or other shoulder muscles) downward (toward the back), then moves toward the spine, then moves toward the neck, and finally returns to the initial position. This reciprocating kneading is achieved. Of course, you can also move in the opposite direction, moving from the initial position toward the neck...

[0076] For another example, when the first massage part is used for back massage, the third curve includes the second annular curve, which can move from the side of the human body to the spine, and after reaching the first set position, move to the neck. After reaching the second set position above the first set position, it moves from the spine to the side of the human body. Kneading is achieved by reciprocating in this way. Of course, it can also move in the opposite direction.

[0077] Alternatively, the third curve moves from the initial position along the latissimus dorsi (or other back muscles) downward (toward the buttocks), then moves toward the spine, then moves toward the shoulder, and finally returns to the initial position. This reciprocating kneading is achieved. Of course, the reverse movement is also possible.

[0078] It should be noted that there is no limit to the number of the first massage heads 410, including but not limited to 1, 2, 3, etc., and can be flexibly designed according to actual massage needs.

[0079] For example, when the first massage head is used to massage the shoulders of a human body, if there are two first massage heads, the movement of the second massage element can drive the two first massage heads to massage the upper and lower parts of the shoulders of a human body at the same time.

[0080] For another example, when the first massage head is used to massage the back of a human body, if there are three first massage heads, the movement of the first massage element can drive the three first massage heads to massage the upper, middle and lower parts of the back simultaneously.

[0081] For another example, when there are two first massage heads, the movement of the first massage part can drive the two second massage heads to massage the back and waist of the human body. For another example, when there are three first massage heads, the movement of the first massage part can drive the three first massage heads to massage the thighs.

[0082] like Figure 3 As shown, the axial direction of the rotating shaft 321 is set in the same direction as the X direction. The X direction is set in the same direction as the width direction of the neck 22 or the shoulder width direction, and the radial direction of the rotating shaft 321 is set in the same direction as the Y direction. The Y direction is set in the same direction as the length direction of the neck 22 or the length direction of the spine. When the user wears the massage device to massage the shoulders and neck of the human body, the second massage head 3321 usually squeezes and kneads the muscles of the human neck from the side of the human neck 22, and the first massage head 3311 kneads the muscles of the human shoulder from the front of the human shoulder 21.

[0083] like Figure 3 as well as Figure 4 As shown, in some embodiments, the first massage head 331 can knead the human shoulder 21 along the third curve 301. In this way, during the reciprocating motion of the first massage head 3311 along the third curve 301, the first massage head 3311 can gradually increase the massage intensity, and then gradually reduce the massage intensity, thereby kneading and massaging the human shoulder and improving the massage effect of the shoulder.

[0084] like Figure 3As shown, the neck width direction and the shoulder width direction are in the same direction as the X direction, the spine length direction and the neck 22 length direction are in the same direction as the Y direction, and the spine thickness or muscle thickness direction is in the same direction as the Z direction. In some embodiments, the third curve 301 includes a first track 3011 that moves the first massage head 410 toward the rotation axis 321 and simultaneously moves the first massage head 410 toward the direction of the stopper 332, and a second track 3012 that moves the first massage head 410 away from the rotation axis 321 and simultaneously moves the first massage head 410 toward the direction of the stopper 332, and the first track 3011 and the second track 3012 are connected end to end. In this way, when the first massage head 410 moves along the first track 3011, the massage intensity can be gradually increased from the back to the neck 22. When the first massage head 410 moves along the second track 3012, the massage intensity can be gradually reduced from the neck 22 to the back, so as to achieve kneading massage of human muscles and enhance the massage effect of the shoulders 21.

[0085] It can be understood that when the first massage head 410 moves along the first trajectory 3011, the eccentricity of the eccentric rotating part 3123 driving the shoulder 21 to move gradually increases during the process of the eccentric rotating part 3123 rotating with the driving member 322. When the first massage head 410 moves along the second trajectory 3012, the eccentricity of the eccentric rotating part 3123 driving the shoulder 21 to move gradually decreases during the process of the eccentric rotating part 3123 rotating with the driving member 322.

[0086] It should be noted that the first motor mechanism includes devices that directly provide rotational power, such as servo motors and rotating hydraulic cylinders, and also includes 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 sliders 343 mechanisms, servo motors + reduction gear boxes, servo motors + flexible transmission mechanisms, etc., which can drive the rotating shaft 321 to rotate.

[0087] See you later Figure 1 , and combined with Figure 6 As shown, in some embodiments, the first driving mechanism 200 includes a first motor 210 disposed on the bearing assembly 100 and a second transmission assembly 220 that is in transmission cooperation with the rotating shaft 321, and the first motor 210 drives the rotating shaft 321 to rotate through the second transmission assembly 220. In this way, the rotation of the rotating shaft 321 is achieved through the cooperation between the first motor 210 and the second transmission assembly 220, so that the position between the first motor 210 and the rotating shaft 321 can be flexibly set, reducing the design difficulty of the massage device 10.

[0088] For example, the second transmission assembly 220 includes a belt transmission assembly, a chain transmission assembly, a gear transmission assembly, and the like.

[0089] like Figure 1 as well as Figure 6 As shown, in some embodiments, the massage components 300 include two groups, and are symmetrically spaced on the bearing assembly 100 along the axis direction of the rotating shaft 321. The first motor 210 drives the two rotating shafts 321 to rotate synchronously through the second transmission assembly 220. In this way, the two groups of massage components 300 can be used to massage the muscles of the two shoulders 21 on both sides of the cervical spine, thereby improving the massage area of ​​the massage device 10. In addition, by realizing the synchronous rotation of the rotating shafts 321 of the two massage components 300 through the first motor 210 and the second transmission assembly 220, the power source can be reduced, and the manufacturing cost of the massage device 10 can be reduced.

[0090] Alternatively, if Figure 1 as well as Figure 6 As shown, in some embodiments, the second transmission assembly 220 includes a transmission gear 221 rotatably disposed on the bearing assembly 100, a first turbine 222 coaxially connected to the transmission gear 221, and two gear sets 223 meshing with the transmission gear 221, the motor includes a first worm 211 that is transmission-matched with the first turbine 222, and the two gear sets 223 correspond to the two groups of massage components 300 one by one, respectively, so as to drive the two rotating shafts 321 to rotate synchronously. In this way, when the massage device 10 is used, the first motor 210 outputs power, and drives the first turbine 222 to rotate through the first worm 211, and then can drive the two groups of gear sets 223 to rotate through the transmission gear 221, and drive the two rotating shafts 321 to rotate synchronously, and then drive the massage parts on the two connecting assemblies 330 to rotate synchronously to achieve massage of the muscles on both sides of the cervical vertebrae and the muscles of the two shoulders 21.

[0091] Optionally, the gear set 223 may be rotatably disposed on the mounting assembly 310 .

[0092] like Figure 2 As shown, in some embodiments, the mounting assembly 310 includes a first mounting member 311 and a second mounting member 312 spaced apart from the first mounting member 311 along the axis direction of the rotating shaft 321 and disposed on the bearing assembly 100. The rotating shaft 321 is rotatably disposed on the first mounting member 311, the first connecting member 331 is disposed close to the first mounting member 311, and the limiting member 332 is disposed close to the second mounting member 312 and movably connected to the second mounting member 312. In this way, the rotating shaft 321 is mounted by the first mounting member 311, so that the connecting assembly 330 is conveniently assembled to the first mounting member 311. At the same time, the second mounting member 312 is movably connected to the limiting member 332 to control the swing trajectory of the limiting member 332, so that the design of the massage component 300 is more flexible. And by connecting the first mounting member 311 and the second mounting member 312 to the bearing assembly 100, it is convenient to modularly assemble the massage component 300 to the massage device 10, thereby improving the assembly efficiency of the massage device 10.

[0093] It should be noted that there are many ways to flexibly connect the second mounting member 312 and the limiting member 332, such as sliding connection, rotation connection, rotation+sliding, etc.

[0094] like Figure 5 As shown, in some embodiments, the second mounting member 312 is provided with a limiting groove 3121, and the limiting member 332 includes a first limiting body 3321 and a matching body 3322 rotatably connected to the first connecting portion 3222. The first limiting body 3321 is provided with a limiting portion 3001 that is limitedly matched with the limiting groove 3121. The limiting portion 3001 is at least partially spherical, and the limiting portion 3001 can rotate in the limiting groove 3121 and can slide in the limiting groove 3121. In this way, when the driving member 322 drives the limiting member 332 to move, the limiting portion 3001 rotates in the limiting groove 3121 and can slide in the limiting groove 3121, so that the first massage head 410 can move along the set trajectory.

[0095] In other embodiments, the first limiting body 3321 is rotatably connected to the matching body 3322, and the limiting portion 3001 is ball-jointedly matched to the limiting groove 3121. In this way, the first massage head 410 can also move along a set trajectory.

[0096] like Figure 5 As shown, in some embodiments, the stopper 332 further includes a second stopper 3323 disposed on the other side of the matching body 3322 and disposed opposite to the first stopper 3321, and the second stopper 3323 is slidably connected to the first connecting member 331. In this way, the second stopper 3323 is slidably connected to the first connecting member 331, so that the first connecting member 331 swings with the stopper 332 under the drive of the driving member 322, and can slide relative to the stopper 332, so that the distance between the first massage head 410 on the first massage member 400 and the stopper 332 is adjustable, so that the first massage head 410 can knead the human body muscles.

[0097] It should be noted that there are many specific implementations of the sliding connection between the second limiting body 3323 and the first connecting member 331, including but not limited to the cooperation between the slide rail and the slider 343. Alternatively, in some embodiments, one of the second limiting body 3323 and the first connecting member 331 is provided with a slide groove 3002, and the other is provided with a protrusion 3312 that slides with the slide groove 3002.

[0098] like Figures 6 to 8As shown, in some embodiments, the driving member 322 includes a driving rod 3224 and an eccentric cam 3223 fixedly connected to the driving rod 3224, the driving rod 3224 is provided with a first connecting portion 3222, and the eccentric cam 3223 is provided with an eccentric driving portion 3221. In this way, the driving member 322 is formed by the eccentric cam 3223 and the driving rod 3224 being fixedly connected, which can reduce the manufacturing difficulty of the driving rod 3224.

[0099] It should be noted that there may be a variety of ways to fix the drive rod 3224 and the eccentric cam 3223, including but not limited to snap fixation, screw fixation, riveted fixation, pin fixation, welding fixation, etc.

[0100] like Figures 6 to 8 As shown, in some embodiments, the eccentric cam 3223 is further provided with a convex rib 3201 adjacent to the eccentric driving part 3221, and the first transmission assembly 320 further includes a limiting ring 324 fixedly connected to the eccentric cam 3223, and the limiting ring 324 and the convex rib 3201 are spaced apart to form a limiting structure for limiting the movement of the first connecting member 331 along the axis direction of the eccentric cam 3223. In this way, when the first connecting member 331 is assembled with the eccentric cam 3223, the first connecting member 331 is arranged on the eccentric driving part and is limited by the convex rib 3201. Then, the limiting ring 324 is fixed to the eccentric cam 3223 to form a limiting structure for limiting the movement of the first connecting member 331 along the axis direction of the eccentric cam 3223.

[0101] In some embodiments, the first connecting member 331 is provided with an avoidance groove 3315 for avoiding the convex rib 3201. Thus, by providing the avoidance groove 3315, the convex rib 3201 can be avoided, and the two will not interfere with each other.

[0102] It should be noted that there may be a variety of ways to rotationally connect the driving rod 3224 and the limiting member 332 , including but not limited to a bearing connection, a sleeve connection, and the like.

[0103] And as Figure 8 As shown, the first obtuse angle is a. Optionally, the third obtuse angle includes any one of 95° to 175°, including 100°, 110°, 120°, 130°, 140°, 150°, etc.

[0104] In some embodiments, the first angle between the driving member 322 and the rotating shaft 321 is adjustable. Thus, by adjusting the first angle, the massage range and massage strength of the first massage member 400 can be adjusted.

[0105] Optionally, the first angle a can be adjusted within the range of 95° to 175°, 100° to 160°, 120° to 150°, etc.

[0106] It is understandable that the closer the shoulder 21 is to the cervical vertebrae, the more it will be sunken, and the farther the shoulder 21 is from the cervical vertebrae, the more it will be raised. For example, when the human body muscles need a greater massage force, and / or the uncomfortable position of the shoulder 21 is close to the cervical vertebrae. At this time, increasing the first angle makes the massage range of the first massage part 400 larger, and can produce a greater kneading massage force on the raised part of the shoulder 21. In addition, the swing amplitude of the first massage part 400 is larger, so as to be able to massage the uncomfortable part close to the cervical vertebrae.

[0107] For example, when the human body muscles require a smaller massage force, and / or the shoulder 21 is at a raised position, when the first angle is reduced, the massage range of the first massage member 400 becomes smaller, and the massage force on the raised portion of the shoulder 21 also becomes smaller. The first massage member 400 will knead the raised position away from the cervical vertebrae, and the massage range is more concentrated, so the massage effect on this area is better.

[0108] It should be noted that there are many ways to achieve the adjustable size of the first angle between the driving member 322 and the rotating shaft 321. For example, the driving member 322 is rotatably connected to the rotating shaft 321 and is provided with a locking structure. When the locking structure is loosened, the first angle can be adjusted. When the locking structure is tightened, the first angle is fixed.

[0109] For another example, the driving member 322 is rotatably connected to the rotating shaft 321, and the size of the first angle is adjusted through the connecting rod 323 assembly.

[0110] like Figure 2 , Figures 6 to 8 As shown, in some embodiments, the first transmission assembly 320 further includes a connecting rod 323, one end of the connecting rod 323 is rotatably connected to the second mounting member 312, and the other end of the connecting rod 323 is transmission-connected to one end of the driving member 322. In this way, the driving member 322 and the second mounting member 312 are connected together through the connecting rod 323, so that the force on the driving member 322 is more stable and not easy to be damaged, thereby improving the reliability of the massage device 10.

[0111] like Figure 2 , Figures 6 to 8As shown, in some embodiments, one end of the connecting rod 323 is rotatably connected to the second mounting member 312, and the other end of the connecting rod 323 is rotatably connected to one end of the driving member 322. The other end of the driving member 322 is rotatably connected to the rotating shaft 321, and the first rotating shaft 321 line of the driving member 322 rotating relative to the rotating shaft 321 is not coaxial with the second rotating shaft 321 line of the rotating shaft 321. At least one of the first mounting member 311 and the second mounting member 312 is slidably connected to the bearing assembly 100, so that the distance between the first mounting member 311 and the second mounting member 312 is adjustable. In this way, by adjusting the distance between the first mounting member 311 and the second mounting member 312, the connecting rod 323 and the driving member 322 are driven to rotate, so that the size of the first angle between the driving member 322 and the rotating shaft 321 can be adjusted, so as to adjust the massage range and massage strength of the first massage head 410.

[0112] like Figures 7 to 9 As shown, in some embodiments, the massage device 10 further includes a second driving mechanism 500, which is disposed on the bearing assembly 100 and is used to drive the slidable first mounting member 311 and / or the slidable second mounting member 312 to move so that the distance between the first mounting member 311 and the second mounting member 312 can be adjusted. In this way, the second driving mechanism 500 is used to facilitate adjustment of the distance between the first mounting member 311 and the second mounting member 312, so that the size of the first angle between the driving member 322 and the rotating shaft 321 can be adjusted.

[0113] It should be noted that there are many specific implementation methods for the second drive mechanism 500, including but not limited to power equipment such as pneumatic rods, hydraulic rods, linear motors, etc. that directly drive the movement of the first mounting member 311 and / or the second mounting member 312, and also including a telescopic mechanism that indirectly realizes the telescopic movement of the first mounting member 311 and / or the second mounting member 312 using a gear rack mechanism, a screw nut mechanism, etc.

[0114] like Figures 7 to 9 As shown, in some embodiments, the mounting assembly 310 further includes a first screw 313 rotatably disposed on the bearing assembly 100, and at least one of the first mounting member 311 and the second mounting member 312 is slidably connected to the bearing assembly 100 and is threadedly connected to the first screw 313. In this way, when the first mounting member 311 is slidably connected to the bearing assembly 100 and is threadedly connected to the first screw 313, the first mounting member 311 can be moved by manually or electrically rotating the first screw 313 to adjust the distance between the first mounting member 311 and the second mounting member 312. Moreover, the movement of the first mounting member 311 is achieved by a threaded transmission method, and it is easy to utilize the self-locking characteristics of the thread to achieve the instant rotation and stop of the first mounting member 311.

[0115] And / or, when the second mounting member 312 is slidably connected to the bearing assembly 100 and is threadedly connected to the first screw rod 313, the second mounting member 312 can be moved by manually or electrically rotating the first screw rod 313 to adjust the spacing between the second mounting members 312. Moreover, the movement of the second mounting member 312 is achieved by thread transmission, and it is easy to utilize the self-locking characteristics of the thread to achieve the instant stop of the second mounting member 312.

[0116] In combination with the above-mentioned embodiment of the second driving mechanism 500, the second driving mechanism 500 is disposed on the bearing assembly 100, and is used to drive the first screw rod 313 to rotate. In this way, the first screw rod 313 can be driven to rotate in an electric manner to achieve automatic adjustment of the first angle.

[0117] like Fig. 9 As shown, in some embodiments, the second driving mechanism 500 includes a second motor 510 and a second turbine 520 rotatably disposed on the bearing assembly 100, the second motor 510 is provided with a second worm 511 that is transmission-coordinated with the second turbine 520, and the second turbine 520 is coaxially rotatably connected with the first screw 313. In this way, when the size of the first angle needs to be adjusted, the second motor 510 outputs power, and drives the second turbine 520 to rotate through the second worm 511, thereby driving the first screw 313 to rotate coaxially and synchronously, realizing the adjustment of the spacing between the first mounting member 311 and the second mounting member 312, so as to complete the automatic adjustment of the first angle.

[0118] Optionally, refer to Figure 8 It is understood that in some embodiments, the first mounting member 311 and the second mounting member 312 are respectively slidably connected to the bearing assembly 100, and the first screw rod 313 includes a first threaded body 3131 threadedly connected to the first mounting member 311 and a second threaded body 3132 threadedly connected to the second mounting member 312, and the first threaded body 3131 and the second threaded body 3132 have opposite threaded directions. In this way, when the first screw rod 313 rotates, it can synchronously drive the first mounting member 311 and the second mounting member 312 to move toward or away from each other, thereby adjusting the distance between the two, and the distance adjustment speed is fast.

[0119] In some other embodiments, optionally, Figure 8As shown, in some embodiments, the first mounting member 311 and the second mounting member 312 are respectively slidably connected to the bearing assembly 100, and the first screw rod 313 includes a first threaded body 3131 threadedly connected to the first mounting member 311 and a second threaded body 3132 threadedly connected to the second mounting member 312, and the first threaded body 3131 and the second threaded body 3132 have different pitches. In this way, when the first screw rod 313 rotates, due to the different pitches of the first threaded body 3131 and the second threaded body 3132, the first mounting member 311 and the second mounting member 312 can be synchronously driven to move toward or away from each other, so as to adjust the distance between the two.

[0120] The ratio of the pitch of the first screw 3131 to the pitch of the second screw body 3132 is 3:1 to 1:3, or 1:1.1 to 1:3, etc.

[0121] In one example, the ratio of the pitch of the first screw 3131 to the pitch of the second screw body 3132 is 1:1.2, or 1:1.3, or 1:1.4, etc.

[0122] In combination with the above-mentioned embodiment of the transmission gear 221, the first mounting member 311 is slidably connected to the bearing assembly 100, and the sliding direction of the first mounting member 311 is arranged in the same direction as the axial direction of the transmission gear 221, and the length of the transmission teeth of the transmission gear 221 is greater than the sliding distance of the first mounting member 311. In this way, even if the first mounting member 311 moves, it is possible to ensure that the gear set 223 is meshed with the transmission gear 221 to drive the rotating shaft 321 to rotate.

[0123] In combination with the above-mentioned embodiment of the two groups of massage components 300, the first threaded bodies 3131 of the two first screws 313 have opposite threaded directions, and the second threaded bodies 3132 of the two first screws 313 have opposite threaded directions, and the second driving mechanism 500 can drive the first screws 313 of the two groups of massage components 300 to rotate synchronously. In this way, the second driving mechanism 500 can drive the rotating shafts 321 of the two first screws 313 to rotate synchronously, which can reduce the power source and reduce the manufacturing cost of the massage device 10.

[0124] In combination with the aforementioned embodiment of the second turbine 520 , the second turbine 520 is coaxially rotatably connected to the first screws 313 of the two groups of massage components 300 .

[0125] In other embodiments, the first mounting member 311 is fixed to the bearing assembly 100, the second mounting member 312 is slidably connected to the bearing assembly 100, and the first screw rod 313 is threadedly connected to the second mounting member 312. In this way, the spacing between the first mounting member 311 and the second mounting member 312 can be adjusted, and the first mounting member 311 is fixed, which can reduce the design difficulty of the first driving mechanism 200.

[0126] like Figure 8 As shown, in some embodiments, the second mounting member 312 includes a mounting body 3122 and a rotating portion 3123 rotatably disposed on the mounting body 3122, the connecting rod 323 is transmission-connected to the rotating portion 3123, and the rotating axis 321 of the rotating portion 3123 is coaxially disposed with the second rotating axis 321. In this way, the rotating portion 3123 is used to easily realize the rotational connection between the connecting rod 323 and the second mounting member 312, and because the rotating axis 321 of the rotating portion 3123 is coaxially disposed with the second rotating axis 321, the rotation of the driving member 322 is more stable, the wear is reduced, and the durability is improved.

[0127] In other embodiments, the other end of the connecting rod 323 is fixedly connected to one end of the driving member 322, and the other end of the driving member 322 is fixedly connected to the rotating shaft 321. In this way, the driving member 322, the first mounting member 311, the second mounting member 312 and the rotating shaft 321 are connected into a whole by the connecting rod 323, and the non-coaxial synchronous rotation of the driving member 322 and the rotating shaft 321 is realized.

[0128] Optionally, the connecting rod 323, the driving member 322 and the rotating shaft 321 are integrally formed into a crankshaft shape.

[0129] like Fig.10 As shown, in some embodiments, the first connecting member 331 includes a body 3313 that is transmission-connected to the eccentric driving part 3221 and a guide body 3314 that is slidably connected to the body 3313, and the first massage member 400 is disposed at the end of the guide body 3314. In this way, the extension length of the first massage member 400 is adjustable through the sliding connection between the guide body 3314 and the body 3313, thereby increasing the massage range and flexibly adjusting the position that the user needs to massage. For example, when the trapezius muscle close to the neck 22 needs to be massaged, the guide body 3314 is retracted into the body 3313, and the first massage member 400 is shortened to massage the trapezius muscle. When the rhomboid muscle far from the neck 22 needs to be massaged, the guide body 3314 is extended out of the body 3313, and the first massage member 400 is extended, so that the first massage head 410 on the first massage member 400 can massage the rhomboid muscle.

[0130] Of course, the extension length of the first massage member 400 can also be adjusted according to different massage requirements of the shoulder 21 muscles, for example, the extension length of the first massage member 400 can be adjusted according to different massage positions on the trapezius muscle or rhomboid muscle.

[0131] In some embodiments, the massage component 300 further includes a telescopic drive assembly 340, which is used to drive the guide body 3314 to reciprocate relative to the body 3313. In this way, the position between the guide body 3314 and the body 3313 can be electrically controlled by the telescopic drive assembly 340 to achieve adjustable extension length of the first massage member 400.

[0132] There are many ways to implement the telescopic drive assembly 340, including but not limited to power equipment such as pneumatic rods, hydraulic rods, linear motors, etc. that directly drive the guide body 3314, and also including telescopic mechanisms that indirectly realize the telescopic movement of the guide body 3314 using gear rack mechanisms, screw nut mechanisms, etc.

[0133] like Fig.10 As shown, in some embodiments, the telescopic drive assembly 340 includes a drive motor 341 disposed on the body 3313, a screw rotatably disposed on the body 3313, and a slider 343 fixedly connected to the guide body 3314. The slider 343 is threadedly connected to the screw. The drive motor 341 can drive the screw to rotate, thereby driving the slider 343 to move along the axis of the screw, thereby driving the guide body 3314 to move relative to the body 3313, thereby adjusting the extension length of the first massage member 400. This embodiment is easy to implement and has a compact structure.

[0134] In some embodiments, the first massage members 400 include at least two, and at least two of the first massage members 400 have different shapes. In this way, when the massage device 10 is used, the user can flexibly replace the first massage members 400 according to the different locations of the discomfort parts and / or personal preferences to meet different massage needs.

[0135] It should be noted that the different shapes of the first massage parts 400 should be understood in a broad sense, including different numbers and / or shapes of massage heads. For example, there may be 1 massage head, 2 massage heads, or 3 massage heads. Alternatively, the shapes of the massage heads include but are not limited to spherical, cylindrical, barbell, etc. In addition, similar shapes of the first massage parts 400 also belong to different shapes.

[0136] In addition, the first massage element includes at least one of a shoulder massage element, a back massage element, a waist massage element, a hip massage element, and a thigh massage element, etc. The massage device is connected to different types of first massage elements through the first connecting element to achieve massage of different parts of the human body.

[0137] It should be noted that there may be a variety of detachable connection methods between the second connection portion 3311 and the first massage member 400, including but not limited to screw fixation, snap fixation, plug fixation, etc.

[0138] like Fig.11As shown, in some embodiments, at least one of the second connection part 3311 and the first massage part 400 is provided with a plug-in slot 3301, and the other is provided with a plug-in body 420 that is tightly matched with the plug-in slot 3301. In this way, the second connection part 3311 and the first massage part 400 can be detachably connected by the plug-in body 420 and the plug-in slot 3301, which is easy to implement and convenient to assemble.

[0139] It should be noted that the tight fit includes transition fit and interference fit, such as elastic squeeze fit, friction fit, etc.

[0140] Optionally, the plug-in body 420 is in a non-cylindrical shape, and the plug-in slot 3301 is adapted to the plug-in body 420. For example, the plug-in body 420 is in a polygonal column or an elliptical column shape.

[0141] In combination with any of the above embodiments, in some embodiments, the massage device 10 further includes a massage device (not shown), which is disposed on the bearing assembly 100 and is used to massage the human neck 22. In this way, the massage device can massage two parts of the human body. For example, the neck of the human body is massaged by the massage device, and the shoulders of the human body are massaged by the first massage head. In addition, the massage device can massage the shoulders and neck of the human body, thereby improving the user experience.

[0142] like Fig.12 As shown, in some other embodiments, the massage device 10 further includes a second massage member 600, which is detachably connected to the stopper 332, so that the second massage member 600 can at least knead the human body 22 under the drive of the driving member 322. In this way, when using the massage device, the user can flexibly install the second massage head according to the massage needs to massage two parts of the human body (such as the human shoulder and the human neck) at the same time. In addition, when the user only has shoulder discomfort, the second massage head can be removed from the stopper, and only the first massage head can be used to massage the human shoulder.

[0143] Furthermore, if Fig.12 As shown, in some embodiments, the second massage member 600 includes a second massage head 610, which can knead the human neck 22 under the drive of the driving member 322. In this way, when the limiting member 332 swings with the driving member 322, the second massage head 610 can simulate the trajectory of kneading the neck 22 by human hands, realize kneading and massaging the human neck 22, and enhance the massage effect of the shoulders 21.

[0144] It should be noted that there is no limit to the number of the second massage heads 610, including but not limited to 1, 2, 3, etc., and can be flexibly designed according to actual massage needs.

[0145] For example, when the second massage head is used to massage the human neck, if there are two second massage heads, the movement of the second massage element can drive the two second massage heads to massage the upper and lower parts of the human neck at the same time.

[0146] For another example, when the second massage head is used to massage the back of a human body, if there are three second massage heads, the movement of the second massage element can drive the three second massage heads to massage the upper, middle and lower parts of the back simultaneously.

[0147] For another example, when there are two second massage heads, the two second massage heads can be driven by the movement of the second massage element to massage the back and waist of the human body. For another example, when there are three second massage heads, the three second massage heads can be driven by the movement of the second massage element to massage the thighs.

[0148] In addition, the second massage element includes at least one of a neck massage element, a shoulder massage element, a back massage element, a waist massage element, a hip massage element, and a thigh massage element, etc. The massage device can connect different types of second massage elements through the limiter to achieve massage of different parts of the human body.

[0149] In some embodiments, the position-limiting member 332 is limitedly matched with the mounting assembly 310 so that the position-limiting member 332 moves along a set first curve. The first connecting member 331 is slidably connected to the position-limiting member 332 so that the second connecting portion 3311 moves along a set second curve. In this way, the driving member 322 can drive the first massage member 400 and the second massage member 600 to rotate eccentrically relative to the first axis synchronously. Moreover, the eccentric driving portion 3221 can also drive the first massage member 400 to swing relative to the second massage member 600, so that the motion trajectory between the first massage member 400 and the second massage member 600 can be independently designed according to the curve of the desired massage part, so as to better fit the corresponding part for massage and improve the massage effect of the massage device.

[0150] It should be noted that the "limiting cooperation" between the limiter 332 and the mounting assembly 310 should be understood in a broad sense, and the two can move relative to each other, but the movement trajectory is limited by the other. Specifically, the limiter 332 can move relative to the mounting assembly 310, but the movement trajectory of the limiter 332 is limited by the mounting assembly 310. Specifically, the limiter 332 is slidably connected to the mounting assembly 310 and can rotate relative to the mounting assembly 310.

[0151] like Fig.13As shown, in some embodiments, the second massage head 610 includes a first massage part 611 and a second massage part 612 spaced apart from the first massage part 611. Relative to the first massage part 611, the second massage part 612 is disposed close to the first massage head 410 of the first massage member 400. The stopper 332 is movably connected to the mounting assembly 310 so that the stopper 332 can rotate with the driving member 322 and drive the first massage part 611 to reciprocate along the fourth curve 613 and drive the second massage part 612 to reciprocate along the fifth curve 614. When the first massage part 611 moves in a direction of squeezing the human neck 22, the second massage part 612 moves in a direction away from the human neck 22. When the first massage part 611 moves in a direction away from the human neck 22, the second massage part 612 moves in a direction of squeezing the human neck 22. In this way, the upper end of the neck 22 (that is, the part close to the human head) can be kneaded and massaged by the reciprocating motion of the first massage part 611 along the fourth curve 613. The second massage part 612 can knead and massage the lower end of the neck 22 (i.e., the part close to the human body muscles) by reciprocating along the fifth curve 614. Moreover, when the first massage part 611 moves in a direction of squeezing the human neck 22, the second massage part 612 moves in a direction away from the human neck 22. When the first massage part 611 moves in a direction away from the human neck 22, the second massage part 612 moves in a direction of squeezing the human neck 22, so that the first massage part 611 and the second massage part 612 can swing relative to the first connection part 3222 along the length direction of the human neck 22, and massage the neck 22 alternately in sequence, thereby improving the massage effect of the neck 22.

[0152] Optionally, the muscle groups of the shoulder and neck 22 include levator scapulae, trapezius and rhomboid muscles, etc. Since the muscle curves of the trapezius and levator scapulae are different, the muscle groups of the shoulder and neck 22 are better relaxed. In some embodiments, the first curve 301 includes a first track 3011 that moves the first massage head 410 toward the direction of the rotation axis 321 and simultaneously moves the first massage head 410 toward the direction of the second massage head 610, and a second track 3012 that moves the first massage head 410 away from the rotation axis 321 and simultaneously moves the first massage head 410 toward the direction of the second massage head 610, and the first track 3011 is connected to the second track 3012 end to end. When the first massage head 410 moves along the first track 3011, the second massage part 612 moves toward squeezing the human neck 22 and moves toward the direction of the first massage head 410. In this way, the second massage part 612 and the first massage head 410 achieve pinching of the head and neck splenius and / or levator scapulae. When the first massage head 410 moves along the second trajectory 3012, the second massage part 612 moves away from the human neck 22 and the first massage head 410. In this way, the second massage part 612 and the first massage head 410 release the pinching of the cervical flexor muscles and the levator scapulae muscles, and use the first massage head 410 to knead and massage the levator scapulae muscles and / or the trapezius muscles, thereby improving the massage effect on the human body muscles.

[0153] It should be noted that "kneading movement" should be understood in a broad sense, including reciprocating swinging, reciprocating rotation, and reciprocating movement along a set trajectory. The massage intensity on the human muscles can be reciprocated from light to heavy.

[0154] It should be noted that the "convex ridge" can be "a part of the eccentric cam", that is, the "convex ridge" and "other parts of the eccentric cam, such as the eccentric drive part" are integrally formed and manufactured; it can also be an independent component that can be separated from the "other parts of the eccentric cam, such as the eccentric drive part", that is, the "convex ridge" can be manufactured independently and then combined with the "other parts of the eccentric cam, such as the eccentric drive part" into a whole. The expression of the above-mentioned "certain body" and "certain part" in the present disclosure is only one of the embodiments, for the convenience of reading, and not to limit the scope of protection of the present disclosure. As long as it contains the above-mentioned features and has the same function, it should be understood as an equivalent technical solution of the present disclosure.

[0155] It should be noted that the "first screw" can be one of the parts of the "installation component" module, that is, it can be assembled into a module with the "other components of the installation component" and then assembled modularly; it can also be relatively independent of the "other components of the installation component" and can be installed separately, that is, it can form a whole with the "other components of the installation component" in this device.

[0156] Equivalently, the components included in the "assembly", "component" and "mechanism" of the present disclosure can also be flexibly combined, that is, modular production can be carried out according to actual conditions, modular assembly can be carried out as an independent module; or they can be assembled separately to form a module in the present device. The division of the above components in the present disclosure is only one of the embodiments, for the convenience of reading, and not to limit the scope of protection of the present disclosure. As long as the above components are included and have the same functions, it should be understood that it is an equivalent technical solution of the present disclosure.

[0157] When one component is considered to be "transmission-connected" to another component, the two can be fixed in a detachable manner or in a non-detachable manner as long as power transmission can be achieved, such as socketing, snap-fitting, one-piece molding, welding, etc., which can be achieved in traditional technologies and will not be repeated here.

[0158] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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.

[0159] The above embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
