DETAILED DESCRIPTION

[0068] 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.

[0069] 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.

[0070] 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.

[0071] At present, due to the increasing number of people sitting for long periods of time at work and in life, people are prone to discomfort in the neck and / or shoulders, resulting in an increasing market demand for massage devices that can massage the above parts. For example, a shoulder and neck massage device is a massage device specially designed for the shoulder curve and the neck curve, which can use the shoulder massage piece to massage the shoulder muscles to relax them and effectively relieve the fatigue of the shoulder muscles. At the same time, the neck massage piece can be used to massage the neck muscles to relax them and effectively relieve the fatigue of the neck muscles.

[0072] In the related art, the massage range of the massage head of some massage devices is adjustable to meet the massage needs of people of different body types. For example, in addition to the driving power source that drives the massage component to move, it is also necessary to set a spacing adjustment mechanism to achieve the spacing adjustment between the two groups of massage components, and / or use an angle adjustment mechanism to adjust the massage range of the massage component to adapt to the selection of different massage parts, or to meet the massage needs of people of different body types for the same part. At this time, this type of massage device needs to integrate the massage component into an adjustment mechanism that can adjust the massage range of the massage component, and then install two adjustment mechanisms with integrated massage components on the bearing components respectively, and then use a transmission structure (such as a screw nut mechanism, a gear rack mechanism, etc.) to drive the massage component to move. At this time, two adjustment mechanisms are needed, which requires a large space, resulting in a large overall volume of the massage device, which is not conducive to the miniaturization of the massage device.

[0073] Based on this, the present disclosure provides a supporting device that can be used to install a massage component and drive the massage component to move and adjust the massage range of the massage component. It has a compact structure and occupies a small space, which is conducive to the miniaturization of the massage equipment.

[0074] In order to better understand the supporting device of the present disclosure, a massage device using the supporting device is described below.

[0075] like Figure 1 As shown, in some embodiments, a massage device 10 is provided, including a carrying device 100, a power source 200, a first massage component 300 movably disposed on a first carrying component 110, and a second massage component 400 movably disposed on a second carrying component 120.

[0076] The bearing device 100 includes a first bearing assembly 110, a second bearing assembly 120 and a transmission assembly 130. The first bearing assembly 110 is provided with a first mounting portion 110a for mounting the first massage assembly 300. The second bearing assembly 120 is rotatably connected to the first bearing assembly 110, and the second bearing assembly 120 is provided with a second mounting portion 120a for mounting the second massage assembly 400. The transmission assembly 130 includes a power shaft 131 rotatably disposed on at least one of the first bearing assembly 110 and the second bearing assembly 120, a driving member 132 transmission-connected to the power shaft 131, a first driven member 133 for driving the first massage assembly 300 to move, and a second driven member 134 for driving the second massage assembly 400 to move. The power shaft 131 drives the first driven member 133 and the second driven member 134 to move through the driving member 132. The rotation axis of the power shaft 131 is on the same straight line as the rotation axis of the second bearing assembly 120.

[0077] When the massage device 10 is used, the first bearing assembly 110 is installed with the first massage assembly 300, and the second bearing assembly 120 is installed with the second massage assembly 400. The first bearing assembly 110 is rotatably connected with the second bearing assembly 120. The first bearing assembly 110 and the second bearing assembly 120 can rotate relative to each other, so that the angle between the first bearing assembly 110 and the second bearing assembly 120 is adjustable, and the massage range of the first massage assembly 300 and the second massage assembly 400 is adjustable to meet different massage needs.

[0078] The bearing device 100 also integrates a transmission component 130 that can drive the first massage component 300 and the second massage component 400 to move, and the rotation axis of the power shaft 131 of the transmission component 130 is in the same straight line as the rotation axis of the second bearing component 120, which can prevent the second bearing component 120 or the first bearing component 110 from making eccentric movements relative to the power shaft 131, reduce motion interference, and make the structure of the massage device 10 more compact. In this way, the bearing device 100 can be used to install the massage component and drive the massage component to move and adjust the massage range of the massage component. The structure is compact and occupies little space. Furthermore, after the massage device 10 uses the bearing device 100, the volume can be reduced, which is conducive to miniaturization.

[0079] It can be understood that during the rotation of the second bearing assembly 120 relative to the first bearing assembly 110, the power of the power source 200 can also be output through the first follower 133 and the second follower 134, so that the bearing device 100 integrates the massage range adjustment structure and the transmission assembly 130 for outputting two powers from one power source 200, and has a compact structure. Compared with the traditional technology, the adjustment mechanism is reduced and the space occupied is small.

[0080] In addition, the power source 200 drives the first massage component 300 and the second massage component 400 to rotate through the transmission component 130 , which can save the power source 200 and help reduce the cost of the massage device 10 .

[0081] It should be noted that “the rotation axis of the power shaft 131 and the rotation axis of the second bearing assembly 120 are in the same straight line” should be understood in a broad sense, allowing a certain coaxiality error to reduce motion interference and make the structure of the massage device 10 more compact.

[0082] In addition, since the first bearing assembly 110 is rotatably connected to the second bearing assembly 120, the rotation axis of the first bearing assembly 110 is in the same straight line as the rotation axis of the second bearing assembly 120. When a force is applied to drive the first bearing assembly 110 to rotate relative to the second bearing assembly 120, the rotation axis of the first bearing assembly 110 and the rotation axis of the power shaft 131 are also in the same straight line.

[0083] In some embodiments, the power shaft 131 is also the connecting shaft for rotatably connecting the first bearing assembly 110 and the second bearing assembly 120. In this way, the structure of the massage device 10 can be made more compact, and the assembly error can be reduced, so that the angle between the first bearing assembly 110 and the second bearing assembly 120 can be adjusted more accurately.

[0084] It should be noted that there may be many specific implementation methods for the first supporting component 110 and / or the second supporting component 120, including being formed by using at least one of a supporting member, a shell, a mounting frame, etc., and may also be formed by splicing multiple shells or multiple components.

[0085] In addition, there may be many specific implementations of the first mounting portion and the second mounting portion, including but not limited to swing connection, ball joint, sliding connection and other movable connection modes, as long as the massage component can be installed. Optionally, the first massage component can move eccentrically and be ball-jointed with the first mounting portion. Alternatively, the first massage component can swing and be slidingly connected with the first mounting portion. The second massage component can move eccentrically and be ball-jointed with the second mounting portion. Alternatively, the second massage component can swing and be slidingly connected with the second mounting portion.

[0086] It should be noted that the "power source 200" should be understood in a broad sense, including power equipment such as motors and rotary hydraulic cylinders that can directly provide rotational power, and also power mechanisms such as motors + transmission gears, motors + worm gears, and motors + flexible transmission mechanisms that can provide rotational power.

[0087] like Figure 1 As shown, in some embodiments, the power shaft 131 includes a shaft body 1311, a first rotating portion 1312 rotatably connected to one end of the shaft body 1311, and a second rotating portion 1313 rotatably connected to the other end of the shaft body 1311. The first bearing assembly 110 is rotatably connected to the first rotating portion 1312 and the second rotating portion 1313, and the second bearing assembly 120 is rotatably connected to the first rotating portion 1312 and the second rotating portion 1313, so that the rotation axis of the power shaft 131 and the rotation axis of the second bearing assembly 120 are in the same straight line. In this way, the power shaft 131 is installed on the first bearing assembly 110 or the second bearing assembly 120 through the first rotating portion 1312 and the second rotating portion 1313, and the power shaft 131 can be rotatably assembled on the first bearing assembly 110 or the second bearing assembly 120, so that the rotation axis of the power shaft 131 and the rotation axis of the second bearing assembly 120 are easily in the same straight line, and the structure is compact.

[0088] Optionally, in some embodiments, there may be various specific implementations of the first rotating portion 1312 and the second rotating portion 1313 , including but not limited to bearings.

[0089] like Figure 1As shown, in some embodiments, the first bearing assembly 110 includes a first mounting frame 111 rotatably connected to the first rotating portion 1312 and a first bearing member 112 fixedly connected to the first mounting frame 111, and the first mounting portion 110a is disposed on the first bearing member 112. In this way, by utilizing the rotatable connection between the first mounting frame 111 and the first rotating portion 1312, it is easy to realize the rotatable connection between the first bearing member 112 and the power shaft 131, so that the power shaft 131 rotates relative to the first bearing assembly 110 to drive the first massage assembly 300 to move.

[0090] It should be noted that there may be many specific implementations of the first mounting frame 111, including but not limited to a connecting frame, a shell, and the like.

[0091] In addition, the first carrier 112 may be specifically implemented in many ways, including but not limited to a carrier plate, a carrier shell 321 and the like.

[0092] like Figure 1 As shown, in some embodiments, the second bearing assembly 120 includes a second mounting frame 121 rotatably connected to the second rotating portion 1313 and a second bearing member 122 fixedly connected to the second mounting frame 121, and the second mounting portion 120a is disposed on the second bearing member 122. In this way, by utilizing the rotatable connection between the second mounting frame 121 and the second rotating portion 1313, it is easy to realize the rotatable connection between the second bearing member 122 and the power shaft 131, so that the power shaft 131 rotates relative to the second bearing assembly 120 to drive the second massage assembly 400 to move.

[0093] It should be noted that there may be many specific implementations of the second mounting frame 121, including but not limited to a connecting frame, a shell, and the like.

[0094] In addition, the second carrier 122 may be implemented in many ways, including but not limited to a carrier plate, a carrier shell, and the like.

[0095] In some embodiments, the active member 132 is fixedly connected to the shaft body 1311 and is disposed between the first rotating portion 1312 and the second rotating portion 1313. In this way, when the transmission assembly 130 is assembled, the active member 132 is firstly fixedly connected to the shaft body 1311, and then the first rotating portion 1312 and the second rotating portion 1313 are installed. Finally, the power shaft 131 and the active member 132 can be installed between the first bearing assembly 110 and the second bearing assembly 120 by using the first rotating portion 1312 and the second rotating portion 1313, which can improve the assembly efficiency of the bearing device 100.

[0096] like Figure 1As shown, in some embodiments, the first follower 133 includes a first follower wheel for transmission connection with the first massage component 300, the transmission component 130 also includes a first flexible transmission component 135, and the driving component 132 includes a first driving wheel 1321, and the first driving wheel 1321 drives the first follower wheel to rotate through the first flexible transmission component 135. In this way, the power source 200 is used to drive the power shaft 131 to rotate, and the driving wheel is driven to rotate through the power shaft 131. The driving wheel can drive the first follower wheel to rotate synchronously through the first flexible component, and then drive the first massage component 300 to rotate. Since the first driving wheel 1321 and the first follower wheel are flexibly transmitted through the first flexible component, the installation position of the first massage component 300 on the first bearing component 110 is more flexible, and it is also convenient to use the first flexible component to avoid other structures (such as control panels, batteries, etc.) on the first bearing component 110, so that the structure of the massage device 10 is more compact to achieve miniaturization.

[0097] It should be noted that the first flexible transmission member 135 includes a belt, a chain, etc.

[0098] In combination with any of the above embodiments, in some embodiments, the second follower 134 includes a second follower wheel for transmission connection with the second massage component 400, the transmission component 130 also includes a second flexible transmission component 136, and the driving component 132 includes a second driving wheel 1322, and the second driving wheel 1322 drives the second follower wheel to rotate through the second flexible transmission component 136. In this way, the power source 200 is used to drive the power shaft 131 to rotate, and the driving wheel is driven to rotate through the power shaft 131. The driving wheel can drive the second follower wheel to rotate synchronously through the second flexible member, and then drive the second massage component 400 to rotate. Since the second driving wheel 1322 and the second follower wheel are flexibly transmitted through the second flexible member, the installation position of the second massage component 400 on the second bearing component 120 is more flexible, and it is also convenient to use the second flexible member to avoid other structures (such as control panels, batteries, etc.) on the second bearing component 120, so that the structure of the massage device 10 is more compact to achieve miniaturization.

[0099] It should be noted that the second flexible transmission member 136 includes a belt, a chain, etc.

[0100] like Figure 2 as well as Figure 3As shown, in some embodiments, the driving member 132 is a driving gear 1323, the first driven member 133 is a first driven gear 1331 that is in transmission cooperation with the driving gear 1323, the second driven member 134 includes a second driven gear 1341 that is in transmission cooperation with the driving gear 1323, and the second driven gear 1341 and the first driven gear 1331 are arranged at intervals along the radial direction of the power shaft 131. In this way, the first driven gear 1331 and the second driven gear 1341 are arranged at intervals along the radial direction of the power shaft 131, and are respectively in transmission cooperation with the driving gear 1323, and then the power can be output along the radial direction of the power shaft 131 by using the transmission assembly 130. The radial space occupied by the power shaft 131 is small, making the structure of the transmission assembly 130 more compact.

[0101] Optionally, in some embodiments, the first driven gear 1331 is rotatably connected to the first bearing assembly 110. The second driven gear 1341 is rotatably connected to the second bearing assembly 120. In this way, the first bearing assembly 110 and the second bearing assembly 120 can rotate relative to each other, and the first bearing assembly 110 outputs the power of the power source 200 through the first driven gear 1331, and the second bearing assembly 120 outputs the power of the power source 200 through the second driven gear 1341, so that the massage range of the massage assembly can be adjusted and the massage movements do not interfere with each other.

[0102] like Figure 2 as well as Figure 3 As shown, in some embodiments, the bearing device 100 further includes a first output shaft 130a rotatably disposed on the first bearing assembly 110, one end of the first output shaft 130a is transmission-connected to the first driven member 133, and the other end of the first output shaft 130a is transmission-connected to the first massage assembly 300. Thus, by providing the first output shaft 130a, it is convenient for the first driven gear 1331 to transmit power to the first massage assembly 300 along the axial direction of the first output shaft 130a, so that the spacing between the first massage assembly 300 and the transmission assembly 130 can be adjusted by the length of the first output shaft 130a. The first output shaft 130a is used to perform transmission connection with the first massage assembly 300 to realize shaft-connected transmission, which makes it easy to realize transmission connection between the transmission assembly 130 and the first massage assembly 300, and is conducive to improving the assembly efficiency of the transmission assembly 130 and the first massage assembly 300.

[0103] It should be noted that there are many specific implementation methods for the transmission connection between the first driven gear 1331 and the first output shaft 130a, as long as force transmission can be achieved, including but not limited to welding, key connection, pin connection, non-cylindrical sleeve connection, etc.

[0104] Optionally, the first massage component is provided with an eccentric wheel drivingly connected to the first output shaft and a massage body drivingly connected to the eccentric wheel, and the massage body is movably connected to the first mounting portion.

[0105] like Figure 2 as well as Figure 3 As shown, in some embodiments, the bearing device 100 further includes a second output shaft 130b rotatably disposed on the second bearing assembly 120, one end of the second output shaft 130b is transmission-connected to the second driven member 134, and the other end of the second output shaft 130b is transmission-connected to the second massage assembly 400. Thus, by providing the second output shaft 130b, it is convenient for the second driven gear 1341 to transmit power to the second massage assembly 400 along the axial direction of the second output shaft 130b, so that the spacing between the second massage assembly 400 and the transmission assembly 130 can be adjusted by the length of the second output shaft 130b. The second output shaft 130b is used to transmit the power to the second massage assembly 400 to realize the shaft-connected transmission, which makes it easy to realize the transmission connection between the transmission assembly 130 and the second massage assembly 400, and is conducive to improving the assembly efficiency of the transmission assembly 130 and the second massage assembly 400.

[0106] It should be noted that there are many specific implementation methods for the transmission connection between the second driven gear 1341 and the second output shaft 130b, as long as force transmission can be achieved, including but not limited to welding, key connection, pin connection, non-cylindrical sleeve connection, etc.

[0107] Optionally, the second massage component is provided with an eccentric wheel drivingly connected to the second output shaft and a massage body drivingly connected to the eccentric wheel, and the massage body is movably connected to the second mounting portion.

[0108] like Figure 3As shown, in some embodiments, the first bearing assembly 110 and the second bearing assembly 120 cooperate to form a first protective cavity 101 for protecting the driving gear 1323, the first driven gear 1331 and the second driven gear 1341. In this way, it is possible to reduce the possibility of the gear structure being stuck or damaged due to the entry of foreign matter, thereby improving the durability and reliability of the massage device 10. The first bearing assembly 110 is provided with a first avoidance gap for avoiding the first output shaft 130a, and the first avoidance gap is connected to the first protective cavity 101; the second bearing assembly 120 is provided with a second avoidance gap for avoiding the second output shaft 130b, and the second avoidance gap is connected to the second protective cavity 102. In this way, when the first output shaft 130a is assembled with the first driven gear 1331, the first output shaft 130a passes through the first avoidance gap along the extension direction of the first connecting portion 1332 and is transmission-connected with the first connecting portion 1332, which is easy to assemble. Similarly, when the second output shaft 130 b is assembled with the second driven gear 1341 , the second output shaft 130 b passes through the second avoidance gap along the extension direction of the second connection portion 1342 to be transmission-connected with the second connection portion 1342 , which is easy to assemble.

[0109] In some embodiments, the first driven gear 1331 is provided with a second connecting portion 1342 which is transmission-connected to the first output shaft 130a.

[0110] Optionally, the first connecting portion 1332 is in non-cylindrical sleeve transmission cooperation with the first output shaft 130a.

[0111] like Figure 3 As shown, in some embodiments, the second driven gear 1341 is provided with a second connecting portion 1342 drivingly connected to the second output shaft 130b.

[0112] Optionally, the second connecting portion 1342 is in non-cylindrical sleeve transmission cooperation with the second output shaft 130b.

[0113] In some embodiments, the driving gear 1323, the first driven gear 1331, and the second driven gear 1341 are bevel gears, so that the rotation axis of the first driven gear 1331 intersects with the rotation axis of the power shaft 131, and the rotation axis of the second driven gear 1341 intersects with the rotation axis of the power shaft 131. In this way, by utilizing the transmission matching characteristics of the bevel gears, the transmission direction can be adjusted from the axial direction of the power shaft 131 to the radial direction of the power shaft 131, so that the transmission assembly 130 and the power source 200 are more closely matched, thereby reducing the volume of the massage device 10, which is conducive to the miniaturization of the massage device 10.

[0114] Optionally, in some embodiments, the rotation axis of the first driven gear 1331 is perpendicular to the rotation axis of the power shaft 131. Thus, the first driven gear 1331 outputs rotational power in the radial direction of the power shaft 131, so that the first massage assembly 300 is arranged in the radial direction of the power shaft 131.

[0115] Optionally, in some embodiments, the rotation axis of the second driven gear 1341 is perpendicular to the rotation axis of the power shaft 131. Thus, the second driven gear 1341 outputs rotational power in the radial direction of the power shaft 131, so that the second massage assembly 400 is arranged in the radial direction of the power shaft 131.

[0116] like Figure 4 as well as Figure 5 As shown, in some embodiments, the first driven gear 1331 and the second driven gear 1341 are respectively meshed with the driving member 132. In this way, the first driven gear 1331 and the second driven gear 1341 are closely matched with the driving gear 1323, which can further improve the compact structure of the transmission assembly 130 and occupy a small space.

[0117] Further, the first driven gear 1331 is rotatably connected to the first bearing assembly 110, and the second driven gear 1341 is rotatably connected to the second bearing assembly 120. In this way, the first driven gear 1331 is directly mounted on the first bearing assembly 110, and the second driven gear 1341 is directly mounted on the second bearing assembly 120, so that the structure of the bearing device 100 is more compact.

[0118] See you later Figure 2 as well as Figure 3 As shown, in some embodiments, the carrying device 100 further includes a transmission gear set 137, one of the first driven gear 1331 and the second driven gear 1341 is meshed with the driving gear 1323, and the other is meshed with the driving gear 1323 through the transmission gear set 137. In this way, the transmission gear set 137 is used to flexibly set the distance between the first driven gear 1331 and the second driven gear 1341 to meet different design requirements.

[0119] It should be noted that the driving gear can drive the first driven gear and the second driven gear to rotate synchronously in the same direction, and can also drive the first driven gear and the second driven gear to rotate synchronously in opposite directions.

[0120] For example, when the first driven gear and the second driven gear are cylindrical gears, when the driving gear is respectively meshed with the first driven gear and the second driven gear, the first driven gear and the second driven gear can be driven to rotate synchronously in the same direction.

[0121] For example, when the first driven gear and the second driven gear are bevel gears and are symmetrically arranged along the radial direction of the driving gear, when the driving gear meshes with the first driven gear and the second driven gear respectively, it can drive the first driven gear and the second driven gear to rotate synchronously in opposite directions.

[0122] For another example, when the first driven gear and the second driven gear are cylindrical gears and are required to rotate in the opposite direction synchronously, the driving gear meshes with the first driven gear and drives the second driven gear to rotate through the transmission gear set, thereby driving the first driven gear and the second driven gear to rotate in the opposite direction synchronously.

[0123] For another example, when the first driven gear and the second driven gear are bevel gears and are required to rotate synchronously in the same direction, the driving gear meshes with the first driven gear and drives the second driven gear to rotate through the transmission gear set, which can drive the first driven gear and the second driven gear to rotate synchronously in the same direction.

[0124] It should be noted that the transmission gear set 137 may have multiple specific gears as long as the first driven gear 1331 and the second driven gear 1341 can rotate synchronously.

[0125] Optionally, in some embodiments, the first driven gear 1331 is meshed with the driving gear 1323, the transmission gear set 137 includes a first driven bevel gear 1371 meshed with the driving gear 1323 and a second driven bevel gear 1372 meshed with the first driven bevel gear 1371, and the second driven bevel gear 1372 is meshed with the second driven gear 1341. In this way, by using the cooperation of the two driven gears, the axes of the second driven gear 1341 and the first driven gear 1331 can be on the same straight line and perpendicular to the axis of the power shaft, and the rotation direction of the first driven gear 1331 is the same as that of the second driven gear 1341.

[0126] like Figure 2 as well as Figure 3 As shown, in some embodiments, the first driven bevel gear 1371 and the second driven bevel gear 1372 are rotatably disposed on the second bearing assembly 120. In this way, when the first driven bevel gear 1371 can rotate with the second bearing assembly 120, it can also mesh with the driving gear 1323 and the second driven bevel gear 1372, without affecting the rotation of the second bearing assembly 120 and the power output of the second driven gear 1341.

[0127] In combination with the above-mentioned embodiment of the first protective cavity 101, in some embodiments, the transmission gear set 137 can be rotatably disposed in the first protective cavity 101. In this way, it is possible to reduce the possibility of foreign matter entering and causing the gear structure to get stuck or damaged, thereby improving the durability and reliability of the massage device 10.

[0128] like Figure 2 As shown, further, in some embodiments, the power shaft 131 and the first driven gear 1331 can be rotatably arranged on the first bearing assembly 110. The second bearing assembly 120 includes a second housing 124 that cooperates with the first bearing assembly 110 to form the first protective cavity 101 and a first gear frame 125 that is fixedly connected to the second housing 124, the second driven gear 1341 can be rotatably arranged on the second housing 124, and the first driven bevel gear 1371 and the second driven bevel gear 1372 are respectively rotatably connected to the first gear frame 125. In this way, the second driven gear 1341 is integrated into the second housing 124, and the first driven bevel gear 1371 and the second driven bevel gear 1372 are installed on the first gear frame 125, and then the second driven gear 1341 is assembled with the transmission gear set 137 through the fixed connection between the first gear frame 125 and the second housing 124. The assembly of the carrying device 100 can be completed by rotating the second carrying component 120 and the first carrying component 110, which can easily improve the assembly efficiency.

[0129] Alternatively, if Figure 3 As shown, in some embodiments, the power shaft 131 and the second driven gear 1341 are spaced apart in the direction of the power shaft 131 to form a matching gap 130c, and the first gear frame 125 is disposed in the matching gap 130c and is fixedly connected to the second housing 124. In this way, the first driven gear 1331 and the second driven gear 1341 can be compactly meshed with the driving gear 1323 and the second driven gear 1341 in the radial direction of the power shaft 131, so that the structure of the transmission assembly 130 is compact.

[0130] Alternatively, if Figure 2 As shown, in some embodiments, the first driven bevel gear 1371 includes a first bevel tooth 1301 and a second bevel tooth 1302 spaced apart from the first bevel tooth 1301 along the rotation axis of the first driven bevel gear 1371, the first bevel tooth 1301 meshes with the driving gear 1323, and the second bevel tooth 1302 meshes with the second driven bevel gear 1372. In this way, by setting the first bevel tooth 1301 to mesh with the driving gear 1323 and the second bevel tooth 1302 to mesh with the second driven gear 1341, the transmission structure in the radial direction of the power shaft 131 can be reduced, so that the driving gear 1323 is closely matched with the second driven gear 1341 through the transmission gear set 137, so that the structure of the transmission assembly 130 is more compact and the volume is smaller.

[0131] Alternatively, if Figure 2 as well as Figure 3As shown, in some embodiments, the first gear frame 125 includes a frame body 1251, a first connecting shaft 1252 fixed to the frame body 1251, and a second connecting shaft 1253 fixed to the frame body 1251. The frame body 1251 is fixedly connected to the second housing 124, the first connecting shaft 1252 is rotationally connected to the first driven bevel gear 1371, and the second connecting shaft 1253 is rotationally connected to the second driven bevel gear 1372. In this way, the transmission gear set 137 is integrated into the frame body 1251 through the first connecting shaft 1252 being rotationally connected to the first driven gear 1331, and the second connecting shaft 1253 being rotationally connected to the second driven gear 1341, and then the transmission gear set 137 is modularly assembled between the driving gear 1323 and the second driven gear 1341 through the frame body 1251, which can improve the assembly efficiency of the transmission assembly 130.

[0132] Optionally, in some embodiments, the first massage component 300 and the second massage component 400 move synchronously and in opposite directions, and can synchronously move in a direction close to the power shaft 131 to achieve a pinching massage effect, thereby improving the massage performance of the massage device 10.

[0133] Optionally, in some embodiments, the first massage component 300 and the second massage component 400 move synchronously and in the same direction to achieve a kneading effect in the same direction to meet different massage performances.

[0134] like Figure 6 or Fig.10 As shown, in one example, the first massage component 300 and the second massage component 400 have the same structure and are symmetrically arranged along the axial direction of the power shaft. The first massage component 300 is installed on the first output shaft 130a through an eccentric wheel, and the second massage component 400 is installed on the second output shaft 130b through an eccentric wheel. At this time, the first output shaft 130a and the second output shaft 130b need to move synchronously in the same direction to drive the first massage component 300 and the second massage component 400 to move synchronously and in opposite directions, and to move synchronously close to the power shaft 131 to achieve a pinching massage effect and improve the massage performance of the massage device 10. At this time, combined with Figure 2 as well as Figure 3 As shown, the first driven gear 1331 is a bevel gear and meshes with the driving gear, and the second driven gear 1341 is a bevel gear and meshes with the driving gear through a transmission gear set, so that the first output shaft 130a and the second output shaft 130b move synchronously in the same direction, so as to drive the first massage component 300 and the second massage component 400 to move synchronously and in opposite directions, and can synchronously move close to the direction of the power shaft 131 to achieve a pinching massage effect.

[0135] It can be understood that the rotation directions output by the first follower and the second follower are the same or opposite, which may be related to the massage effects to be achieved by the first massage component and the second massage component, as well as the transmission structure between the first follower and the first massage component and the transmission structure between the second follower and the second massage component, and the present application does not impose too many restrictions.

[0136] like Figure 2 As shown, in some embodiments, the first bearing assembly 110 is provided with a first receiving groove 113, and the second bearing assembly 120 is provided with a second receiving groove 123 that cooperates with the first receiving groove 113 to form the first protection cavity 101. In this way, through the cooperation of the first receiving groove 113 and the second receiving groove 123, the first protection cavity 101 is easily formed.

[0137] In addition, the setting of the first accommodating groove 113 and the second accommodating groove 123 allows part of the first supporting component 110 and part of the second supporting component 120 to be nested and matched without interfering with the rotation of the two, and can also ensure the protective space of the first protective cavity 101, thereby improving the protective performance of the massage device 10.

[0138] like Figure 2 As shown, in some embodiments, the transmission assembly 130 further includes a driving wheel 138 fixed to the power shaft 131, and the massage device 10 further includes a power source 200 for driving the driving wheel 138 to rotate. In this way, integrating the driving wheel 138 into the power shaft 131 is conducive to further improving the compactness of the structure of the massage device 10.

[0139] In addition, the setting of the driving wheel 138 allows the power source 200 to be flexibly set in the radial direction of the power shaft 131, making full use of the three-dimensional space of the massage device 10 and avoiding the massage device 10 being too large in the axial direction of the power shaft 131.

[0140] Optionally, in some embodiments, the driving wheel 138 is a turbine, and the power source 200 is provided with a worm gear that cooperates with the turbine transmission.

[0141] Optionally, in some embodiments, the driving wheel 138 includes a slave pulley, and the power source 200 is provided with a belt that cooperates with the slave pulley and a driving pulley that cooperates with the belt.

[0142] It should be noted that there may be many specific implementations of the rotational connection between the first bearing assembly 110 and the second bearing assembly 120, including but not limited to hinge connection, bearing connection, coupling connection, pivot connection, etc.

[0143] like Figure 6 as well as Figure 7As shown, in some embodiments, one of the first bearing assembly 110 and the second bearing assembly 120 is provided with a first shaft body 114, and the other is provided with a first matching hole 126 that is rotatably matched with the first shaft body 114. The first shaft bodies 114 include two, and are spaced apart along the two ends of the power shaft 131. The first matching holes 126 include two, and are rotatably matched with the first shaft bodies 114 in a one-to-one correspondence. Among them, the axis of the first shaft body 114 is the rotation axis of the second bearing assembly 120. In this way, through the transmission matching of the first shaft body 114 and the first matching holes 126, it is easy to realize the rotation connection between the first bearing assembly 110 and the second bearing assembly 120, so that the first bearing assembly 110 and the second bearing assembly 120 are convenient to connect. And it is easy to realize that the rotation axis of the power shaft 131 and the rotation axis of the second bearing assembly 120 are on the same straight line.

[0144] In combination with the above-mentioned embodiment of the first protective cavity 101, in some embodiments, the first bearing assembly 110 is provided with a first receiving groove 113 for forming the first protective cavity 101, the first shaft body 114 is disposed on the outer side wall of the first receiving groove 113, and the power shaft 131 is rotatably disposed in the first receiving groove 113. In this way, the first shaft body 114 and the power shaft 131 are respectively mounted on the first bearing assembly 110, which can reduce assembly errors, so that the rotation axis of the power shaft 131 and the rotation axis of the second bearing assembly 120 are on the same straight line.

[0145] It can be understood that the first bearing assembly 110 and the second bearing assembly 120 can rotate relative to each other, so that the angle between the first bearing assembly 110 and the second bearing assembly 120 is adjustable, so that the angle between the first massage assembly 300 and the second massage assembly 400 also changes, and then the massage range of the first massage assembly 300 also changes, and different massage requirements can be used. Compared with the traditional technology, by directly adjusting the swing angle of the bearing assembly integrated with the massage assembly to achieve the massage range adjustment of the massage assembly, the installation structure and the transmission structure can be effectively reduced, so that the structure of the massage device 10 is more compact and the volume is smaller, which is conducive to the miniaturization of the massage device 10.

[0146] like Figure 6 as well as Figure 7As shown, in some embodiments, the bearing device 100 further includes a damping structure 140, which is disposed on the first bearing assembly 110 and the second bearing assembly 120 so that the second bearing assembly 120 is suspended relative to the first bearing assembly 110. In this way, by providing the damping structure 140, the second bearing assembly 120 is suspended relative to the first bearing assembly 110, and the turn and stop are realized. It is convenient for the user to adjust the distance and angle between the first massage assembly 300 and the second massage assembly 400 by rotating the second bearing assembly 120, and then the massage range of the two massage assemblies can be adjusted to meet the massage needs of the user. In some embodiments, when the rotational force received by the second bearing assembly 120 is greater than the resistance generated by the damping structure 140, the second bearing assembly 120 rotates relative to the first bearing assembly 110. When the rotational force received by the second bearing assembly 120 is less than or equal to the resistance generated by the damping structure 140, the second bearing assembly 120 is fixed relative to the first bearing assembly 110. In this way, when the user uses the massage device 10 to perform a massage, and the massage range of the massage component cannot effectively massage the massage part, the user applies force to rotate the second bearing component 120, so that the rotational force received by the second bearing component 120 is less than or equal to the resistance generated by the damping structure 140, and the second bearing component 120 rotates relative to the first bearing component 110, so as to adjust the massage component to a suitable position and effectively massage the massage part. When the user stops rotating the second bearing component 120, the rotational force received by the second bearing component 120 is less than or equal to the resistance generated by the damping structure 140, and the second bearing component 120 is fixed relative to the first bearing component 110, so that the massage component can maintain the adjusted massage range to massage the massage part.

[0147] It should be noted that “the second bearing assembly 120 is suspended relative to the first bearing assembly 110” should be understood in a broad sense. That is, the first bearing assembly 110 and / or the second bearing assembly 120 are rotated by applying force, so that the angle between the first bearing assembly 110 and the second bearing assembly 120 changes. After the force is stopped, the second bearing assembly 120 is suspended relative to the first bearing assembly 110.

[0148] It should be noted that "hovering" can be understood as the rotating part can remain in a certain position when it is not driven by a driving force. For example, a certain rotational force is applied to the first bearing assembly 110 so that the first bearing assembly 110 can rotate, and when the rotational force is cancelled or reduced, the first bearing assembly 110 can stop rotating and be fixed in a certain position. For another example, a certain rotational force is applied to the second bearing assembly 120 so that the second bearing assembly 120 can rotate, and when the rotational force is cancelled or reduced, the second bearing assembly 120 can stop rotating and be fixed in a certain position.

[0149] In addition, hovering is a relative concept, and “the second bearing assembly 120 hovers relative to the first bearing assembly 110” can also be considered as applying a certain rotational force to the first bearing assembly 110 so that the first bearing assembly 110 can rotate, and when the rotational force is canceled or reduced, the first bearing assembly 110 may not rotate and hover relative to the second bearing assembly 120. This also means that the second bearing assembly 120 hovers relative to the first bearing assembly 110.

[0150] It should be noted that the damping structure 140 can be disposed on any rotating component of the first bearing assembly 110 and the second bearing assembly 120 that are rotatably connected, as long as the above requirements are met.

[0151] It should be noted that the damping structure 140 may be implemented in other ways, for example, using the friction plate 142 to increase the rotational friction of the connecting rod assembly. Alternatively, using an elastic member to increase the rotational resistance of the connecting rod assembly. Alternatively, using a magnetic member to increase the rotational resistance of the connecting rod assembly, etc. Alternatively, using a plurality of damping protrusions and grooves to cooperate to achieve damped rotation of the second bearing assembly 120.

[0152] In combination with any of the above embodiments, in some embodiments, the first bearing assembly 110 and / or the second bearing assembly 120 can hover at any angle within the range of 45° to 135°. In this way, the first bearing assembly 110 and / or the second bearing assembly 120 can hover within the range of 45° to 135°, which is defined as a hovering state. The first bearing assembly 110 and / or the second bearing assembly 120 can realize instant rotation and stop in the hovering state, so that the massage range of the massage assembly has a larger adjustment range to improve the user experience of the massage device 10.

[0153] like Figure 7 As shown, in some embodiments, the first bearing assembly 110 includes a first housing 116 provided with a first receiving groove 113. The first bearing assembly 110 is fixedly connected to the first housing 116. The second bearing assembly 120 includes a second housing 124 fixedly connected to the second bearing member 122. The second housing 124 is provided with a second receiving groove 123 that cooperates with the first receiving groove 113 to form a protective cavity. In this way, the first housing 116 is rotatably connected to the second housing 124, and the first receiving cavity 1511 is easily formed with the second receiving groove 123 to form a first protective cavity 101, which can at least protect the power shaft 131 and the driving wheel of the power mechanism, which is conducive to improving the durability of the massage device 10. Moreover, the first housing 116 is rotatably connected to the second housing 124, so that the second bearing assembly 120 rotates relative to the first bearing assembly 110, and it is easy to adjust the spacing and angle between the two massage assemblies to adjust the massage range of the two massage assemblies.

[0154] Optionally, the first carrier 112 and the second carrier 122 are plate-shaped and can also carry energy storage components for supplying power to the power mechanism and control components for controlling the opening and closing of the power mechanism.

[0155] like Figure 7 as well as Figure 8 As shown, in combination with the above-mentioned embodiment of the first shaft body 114, in some embodiments, the damping structure 140 is disposed between the first shaft body 114 and the inner side wall of the first matching hole 126. In this way, the second bearing assembly 120 is rotatably connected to the first bearing assembly 110 by the matching of the first shaft body 114 and the first matching hole 126. The damping structure 140 is disposed between the first shaft body 114 and the inner side wall of the first matching hole 126, so that the damping structure 140 is conveniently built between the first bearing assembly 110 and the second bearing assembly 120, and the matching is tighter, which is conducive to further reducing the volume of the bearing device 100, and further facilitating the miniaturization of the massage device 10.

[0156] like Figure 8 As shown, in some embodiments, the damping structure 140 includes a damping ring 141, which is sleeved on the first shaft 114 and has a damping fit with the inner wall of the first matching hole 126, so that the second bearing assembly 120 is suspended relative to the first bearing assembly 110. In this way, the damping ring 141 is used to realize the suspension motion of the second bearing assembly 120 relative to the first bearing assembly 110, which can save space and make the structure of the bearing device 100 more compact.

[0157] like Figure 8 As shown, in some embodiments, the first bearing assembly 110 includes a first side wall 115, and the second bearing assembly 120 includes a second side wall 127 spaced apart from the first side wall 115 to form a first gap 130d, and the second side wall 127 rotates relative to the first side wall 115. The damping structure 140 includes a friction plate 142, and the friction plate 142 is fixedly arranged in the first gap 130d and frictionally cooperates with at least one of the first side wall 115 and the second side wall 127, so that the second side wall 127 is suspended relative to the first side wall 115. In this way, the friction plate 142 is fixedly arranged in the first gap 130d and frictionally cooperates with at least one of the first side wall 115 and the second side wall 127, which can effectively increase the rotation damping between the second bearing assembly 120 and the first bearing assembly 110, and realize the suspension movement of the second bearing assembly 120 relative to the first bearing assembly 110. The friction plate 142 is arranged in the first gap 130d to save space, making the structure of the bearing device 100 more compact.

[0158] Optionally, in some embodiments, the first bearing assembly 110 is provided with a first receiving groove 113, and the second bearing assembly 120 is provided with a second receiving groove 123 that cooperates with the first receiving groove 113 to form the first protection cavity 101. The first side wall 115 is a side wall of the first receiving groove 113, and the second side wall 127 is a side wall of the second receiving groove 123.

[0159] In combination with the above-mentioned embodiments of the first shell 116 and the second shell 124 , the friction plate 142 is arranged between the first shell 116 and the second shell 124 , which can effectively increase the rotational damping between the second bearing component 120 and the first bearing component 110 , thereby realizing the hovering movement of the second bearing component 120 relative to the first bearing component 110 .

[0160] It can be understood that the damping structure 140 includes at least one of the damping ring 141 and the friction plate 142, which can achieve the second bearing assembly 120 to suspend relative to the first bearing assembly 110. Figure 8 As shown, the damping structure 140 includes a damping ring 141 and a friction plate 142 .

[0161] In combination with any of the above embodiments, Fig. 9 As shown, in some embodiments, one of the first bearing assembly 110 and the second bearing assembly 120 is provided with a first shaft body 114, and the other is provided with a first through hole that is rotatably matched with the first shaft body 114. A screw rod 1141 is provided at one end of the first shaft body 114, and the screw rod 1141 passes through the first through hole and is arranged outside the first through hole. The damping structure 140 includes a fastener 143, and the fastener 143 is screwed and matched with the screw rod 1141 to make the second bearing assembly 120 suspend relative to the first bearing assembly 110. In this way, through the screwing and matching of the fastener 143 and the screw rod 1141, the first bearing assembly 110 and the second bearing assembly 120 can be squeezed and matched, and then the rotation damping between the first bearing assembly 110 and the second bearing assembly 120 can be adjusted to achieve the suspending movement of the second bearing assembly 120 relative to the first bearing assembly 110.

[0162] Combining the above-mentioned embodiments of the first shell 116 and the second shell 124, as Figure 3 as well as Fig. 9As shown, in some embodiments, the first shaft body 114 is fixed to the first housing 116, and the second housing 124 is provided with a first matching hole 126 communicating with the second receiving groove 123, and the first matching hole 126 is a first through hole. The fastener 143 is screwed with the screw rod 1141 to make the first housing 116 and the second housing 124 frictionally matched. In this way, the first housing 116 is easily rotatably connected with the second housing 124 through the cooperation of the first shaft body 114 and the first through hole. And through the screwing cooperation of the fastener 143 and the screw rod 1141, the first housing 116 and the second housing 124 are squeezed and matched, and the rotation damping between the first housing 116 and the second housing 124 can be adjusted, and the second bearing assembly 120 is easily suspended relative to the first bearing assembly 110.

[0163] It can be understood that the damping structure 140 includes at least one of the damping ring 141, the friction plate 142 and the fastener 143, which can achieve the second bearing assembly 120 to suspend relative to the first bearing assembly 110. Fig. 9 As shown, the damping structure 140 includes a damping ring 141 , a friction plate 142 and a fastener 143 .

[0164] like Figures 10 to 16 As shown, in some other embodiments, one of the first bearing assembly 110 and the second bearing assembly 120 is provided with a limiting structure 150, and the other is provided with a control structure 160. The control structure 160 cooperates with the limiting structure 150 to control the second bearing assembly 120 to rotate or fix relative to the first bearing assembly 110. In this way, by integrating the limiting structure 150 and the control structure 160 into the first bearing assembly 110 and the second bearing assembly 120 respectively, the control structure 160 cooperates with the limiting structure 150 to control the second bearing assembly 120 to rotate or fix relative to the first bearing assembly 110, so that the massage range of the first massage assembly 300 and the second massage assembly 400 can be adjusted.

[0165] It should be noted that there may be many specific implementations of the limiting structure 150 and the control structure 160, including but not limited to limiting cooperation between the convex part and the concave part, locking cooperation, etc., and the second supporting component 120 can be rotated or fixed.

[0166] like Fig.12 as well as Fig.13As shown, in some embodiments, the limiting structure 150 includes an internal gear 151, and the control structure 160 includes a control gear set 161 meshing with the internal gear 151. When the control gear set 161 rotates, the internal gear 151 is driven to rotate, so as to drive the second bearing assembly 120 to rotate relative to the first bearing assembly 110. When the control gear set 161 stops rotating, the internal gear 151 stops, so that the second bearing assembly 120 is relatively fixed to the first bearing assembly 110. In this way, through the cooperation between the internal gear 151 and the control gear set 161, it is easy to control the rotation or stop of the internal gear 151, thereby rotating or fixing the second bearing assembly 120.

[0167] In addition, it can be understood that the control gear set 161 can be driven or stopped manually or electrically to control the rotation or stop the rotation of the internal gear 151.

[0168] like Fig.13 as well as Fig.14 As shown, in some embodiments, the inner gear 151 is fixed to the second bearing assembly 120 to form a receiving cavity 1511. The control gear set 161 is rotatably disposed in the receiving cavity 1511. In this way, the receiving cavity 1511 of the inner gear 151 is used to receive the control gear set 161, so that the limiting structure 150 and the control structure 160 are closely matched, which is conducive to reducing the volume of the bearing device 100 and miniaturizing the massage device 10.

[0169] like Figures 13 to 15 As shown, in some embodiments, the inner gear 151 is fixedly mounted on the second bearing assembly 120, and the control gear set 161 is rotatably mounted on the first bearing assembly 110. The bearing device 100 further includes a driving unit 170, which is mounted on the second bearing assembly 120 and is used to drive the control gear set 161 to rotate. In this way, when the driving unit 170 is used to start outputting power, the control gear set 161 can drive the inner gear 151 to rotate, thereby realizing the rotation between the second bearing assembly 120 and the first bearing assembly 110, and realizing the adjustment of the spacing and angle between the first massage assembly 300 and the second massage assembly 400.

[0170] In addition, the inner gear 151 is fixedly mounted on the second bearing assembly 120, and the control gear set 161 is rotatably mounted on the first bearing assembly 110. The assembly is easy and the assembly difficulty is reduced.

[0171] like Fig.13 as well as Fig.14As shown, in some embodiments, the first bearing assembly 110 includes a first housing 116 rotatably connected to the second bearing assembly 120 and a second gear frame 117 fixed to the first housing 116, and the control gear set 161 can be rotatably set on the second gear frame 117. In this way, the first bearing assembly 110 is obtained by assembling the second gear frame 117 with the first housing 116, which can effectively reduce the manufacturing difficulty of the first bearing assembly 110. The second gear frame 117 is convenient for assembly with the control gear set 161, which is conducive to improving assembly efficiency.

[0172] It should be noted that the specific number of gears of the control gear set 161 can be selected according to actual needs, as long as it can drive the internal gear 151 to rotate.

[0173] like Fig.13 as well as Fig.14 As shown, in some embodiments, the control gear set 161 includes a control gear 1611 and at least one third driven gear 1612 meshed with the control gear 1611. The control gear 1611 is rotatably disposed on the second gear frame 117. At least one third driven gear 1612 is rotatably disposed on the second gear frame 117 and is respectively meshed with the inner gear 151. The driving unit 170 is used to drive the control gear 1611 to rotate. In this way, when it is necessary to adjust the massage range of the first massage component 300 and the second massage component 400, the control gear 1611 is driven to rotate by the driving unit 170, and the control gear 1611 drives the inner gear 151 to rotate through the driven gear, thereby driving the second bearing component 120 to rotate relative to the first bearing component 110. When the massage range of the first massage component 300 and the second massage component 400 needs to be fixed, the driving unit 170 stops outputting power, so that the control gear 1611 is fixed, and the rotation of the third driven gear 1612 is also limited, so that the internal gear 151 is fixed, and the first supporting component 110 and the second supporting component 120 are relatively fixed.

[0174] It should be noted that the specific structure of the second gear frame 117 can be various, as long as it can carry the control gear set 161. For example, the second gear frame 117 includes a third connecting shaft 1171 that is rotatably matched with the control gear set 161.

[0175] like Fig.13 as well as Fig.14As shown, in some embodiments, the internal gear 151 is provided with an accommodating cavity 1511, the control gear 1611 and at least one third driven gear 1612 are disposed in the accommodating cavity 1511, and the second gear frame 117 includes a plate 1172 for shielding the accommodating cavity 1511. The first bearing assembly 110 also includes a first cover 118 for shielding the accommodating cavity 1511. The first cover 118 and the plate 1172 are spaced apart along the rotation axis direction of the control gear 1611 to shield the accommodating cavity 1511. In this way, the control gear 1611 and at least one third driven gear 1612 are arranged in the accommodating cavity 1511 of the internal gear 151, and the plate body 1172 and the first cover body 118 are used to cooperate to shield the accommodating cavity 1511, so as to prevent foreign matter from entering between the control gear 1611 and the third driven gear 1612, and / or between the third driven gear 1612 and the control gear 1611, causing gear jamming or gear damage, thereby improving the reliability of massage range adjustment of the massage component.

[0176] It can be understood that the plate body 1172 and the first cover body 118 are used to shield the accommodating cavity 1511, so as to facilitate the storage of lubricant to lubricate the control gear set 161.

[0177] Optionally, in some embodiments, the second gear rack 117 further includes a third connecting shaft 1171 and a fourth connecting shaft 1173 fixed to the plate body 1172, the third connecting shaft 1171 is rotationally connected to the driving wheel, and the third driven gear 1612 corresponds one-to-one to the other fourth connecting shaft 1173 and is rotationally connected.

[0178] It should be noted that there are many specific implementation methods of the drive unit 170, including but not limited to using the rotational power source 200 to directly or intermittently drive the control gear group 161 to rotate, and using a linear power source 200 + a linear-to-rotation transmission mechanism to drive the control gear group 161 to rotate (for example, a linear motor 3241173 + a rack and pinion assembly to drive the control gear group 161 to rotate).

[0179] like Fig.15 As shown, in some embodiments, the drive unit 170 includes an adjusting turbine and an adjusting worm gear that are in transmission cooperation with the control gear 1611, and a motor 173 fixed to the second bearing assembly 120. The output shaft of the motor 173 is fixedly connected to the adjusting worm gear, and the adjusting turbine gear is in transmission cooperation with the adjusting worm gear. In this way, the motor 173 drives the adjusting turbine gear to rotate through the adjusting worm gear, and drives the control gear 1611 to rotate through the adjusting turbine gear, so that the spacing between the motor 173 and the control gear 1611 can be flexibly set, reducing the difficulty of arranging the drive unit 170 and the control gear 1611.

[0180] Optionally, see you later Fig.13 as well as Fig.14As shown, in some embodiments, the control gear 1611 is provided with a second shaft 1601 that is transmission-connected to the adjusting turbine, and the first cover 118 is provided with an avoidance hole for the second shaft 1601 to pass through. In this way, the second shaft 1601 is integrated into the control gear 1611, and when the first cover 118 shields the accommodating cavity 1511, the second shaft 1601 passes through the avoidance hole and is convenient for transmission connection with the adjusting turbine, thereby realizing transmission connection between the control gear 1611 and the adjusting turbine, which can reduce the difficulty of assembly.

[0181] Alternatively, if Fig.13 As shown, in some embodiments, the first cover 118 cooperates with the second bearing assembly 120 to form a second protective cavity 102 for accommodating the adjusting worm and the adjusting turbine. In this way, the second protective cavity 102 is used to protect the adjusting turbine and the adjusting worm, facilitate lubrication of the adjusting turbine and the adjusting worm, and prevent foreign matter from entering between the adjusting turbine and the adjusting worm, causing the gears to get stuck, thereby improving the reliability of the drive unit 170.

[0182] like Fig.13 As shown, in some embodiments, the second bearing assembly 120 includes a second shell 124, a third shell 129 and a fourth shell 1201. The second shell 124 and the third shell 129 are fixedly connected to form a first protective cavity 101. The third shell 129 is fixedly connected to the internal gear 151 so that the accommodating cavity 1511 is connected to the first protective cavity 101. The fourth shell 1201 is fixedly connected to the internal gear 151 and cooperates with the first cover 118 to form a second protective cavity 102. In this way, the second bearing assembly 120 is formed by assembling the second shell 124, the third shell 129 and the fourth shell 1201, which can reduce the manufacturing difficulty of the second bearing assembly 120, and is also convenient to cooperate with the first bearing assembly 110 to form the first protective cavity 101, the accommodating cavity 1511 and the second protective cavity 102, and integrate at least part of the power mechanism, the control gear set 161 and the drive unit 170 together, so that the massage device 10 is more compact and is conducive to miniaturization.

[0183] like Fig.16As shown, in some other embodiments, the limiting structure 150 includes a first limiting portion 152 disposed on the second bearing assembly 120, and the control structure 160 includes a control member 162 movably disposed on the first bearing assembly 110, and the control member 162 is provided with a second limiting portion 1621. When the control member 162 is in a limiting state, the second limiting portion 1621 is limitedly matched with the first limiting portion 152, so that the first bearing assembly 110 and the second bearing assembly 120 are relatively fixed. When the control member 162 is in a released state, the second limiting portion 1621 is separated from the first limiting portion 152, so that the second bearing assembly 120 can rotate relative to the first bearing assembly 110. In this way, by manually operating the control member 162, the control member 162 is switched between the limiting state and the released state, and the control of the second bearing assembly 120 is easily realized.

[0184] It should be noted that there may be many specific implementations of the first limiting portion 152 and the second limiting portion 1621. For example, the first limiting portion 152 includes a plurality of limiting holes, and the second limiting portion 1621 includes a limiting protrusion that cooperates with the limiting holes. Alternatively, the first limiting portion 152 includes a plurality of limiting protrusions, and the second limiting portion 1621 includes a limiting hole that cooperates with the limiting hole. Alternatively, the first limiting hole includes a plurality of locking portions, and the second limiting portion 1621 includes a locking tongue that locks with the locking portion.

[0185] Optionally, in some embodiments, the first limiting portion 152 includes limiting teeth, and the second limiting portion 1621 includes matching teeth meshed with the limiting teeth. In this way, when the control member 162 is in the limiting state, the first bearing assembly 110 and the second bearing assembly 120 are relatively fixed and secure by the matching teeth and the limiting teeth. The limiting teeth and the matching teeth are easy to separate, which facilitates the control member 162 to switch from the limiting state to the released state, or from the released state to the limiting state.

[0186] like Fig.16 As shown, in some embodiments, the control member 162 can be swingably arranged on the first bearing assembly 110, and one end of the control member 162 is provided with a second limiting portion 1621, and the other end is provided with a clamping portion 1622. The first bearing assembly 110 is provided with an elastic buckle 119, and the elastic buckle 119 is snap-fitted with the clamping portion 1622 to lock the control member 162 in a limited position. In this way, when the elastic buckle 119 is snap-fitted with the clamping portion 1622, the control member 162 is reliably locked in the limited position, so that the second bearing assembly 120 and the first bearing assembly 110 are firmly fixed. After the elastic buckle 119 is deformed, it is easy to release the clamping portion 1622, so that the control member 162 is switched to a released state.

[0187] It should be noted that there may be many specific implementations of the first massage component 300 and the second massage component 400, which may be able to move to achieve at least one of pressing, pinching, kneading, etc.

[0188] The first massage component 300 and the second massage component 400 can be used to massage at least one of the neck, shoulders, back, waist, thighs and the like of the human body.

[0189] Optionally, in some embodiments, the first massage component 300 and the second massage component 400 can massage two parts, for example, the neck and the shoulders. Fig.10 As shown, the first massage component 300 and the second massage component 400 both have a neck massage head 10a and a shoulder massage head 10b, which can massage the neck and shoulders of the human body respectively.

[0190] like Fig.10 As shown, in some embodiments, the massage assembly includes a driving arm 310 that is in transmission cooperation with the transmission assembly 130 and a massage head 320 that is fixedly connected to the driving arm 310. In this way, the power source 200 is actuated through the transmission assembly 130, and can drive the massage head 320 to perform massage movements through the driving arm 310 to massage the part of the human body to be massaged.

[0191] Among them, Fig.17 As shown, the massage head 320 also includes a hard convex body 322 and an elastic body 323. The bearing shell 321 is provided with a bearing surface. The hard convex body 322 is connected to the bearing shell 321, and at least a portion of the hard convex body 322 is protruded from the bearing surface. The elastic body 323 is connected to the bearing shell 321. The elastic body 323 includes a massage pressing portion protruding from the bearing surface, and the massage pressing portion wraps the hard convex body 322.

[0192] In this way, the massage head 320 simulates human bones through the hard protrusions 322 and uses the elastic body 323 to simulate human muscles and skin, so that when the massage pressing part presses the massage part, it can simulate the massage effect of human hands, which is beneficial to improving the massage of the massage device 10.

[0193] It should be noted that the material of the hard protrusion 322 includes hard metals such as copper, iron, and aluminum, and hard plastics such as polyphenylene sulfide (PPS), phenolic plastic, polyurethane plastic, epoxy plastic, unsaturated polyester plastic, furan plastic, silicone resin, and acrylic resin.

[0194] The material of the elastomer 323 includes but is not limited to silicone-based thermoplastic elastomer 323, modified polypropylene or thermoplastic polyurethane, silicone and other elastic materials that can simulate the touch of the skin.

[0195] It should be noted that the massage position of the massage pressing part can be flexibly set according to actual needs. For example, the massage pressing part is used to massage at least one of the neck, shoulders, back, waist, thighs and other parts of the human body.

[0196] like Fig.17 As shown, in one embodiment, the hard convex body 322 is retractably disposed on the bearing shell 321, so that the gap between the hard convex body 322 and the massage pressing part can be adjusted. In this way, by adjusting the gap between the hard convex body 322 and the massage pressing part, the deformation space of the massage pressing part can be adjusted, and then the massage hardness of the massage head 320 assembly can be adjusted.

[0197] For example, when a harder massage effect is needed, the hard protrusion 322 moves toward the massage pressure portion, so that the gap between the two is reduced or even becomes zero, thereby reducing the deformable space of the massage pressure portion, so that the massage pressure portion achieves a harder massage effect.

[0198] When a softer massage effect is needed, the hard protrusion 322 moves away from the massage pressure portion, so that the gap between the two becomes larger, which in turn expands the deformable space of the massage pressure portion, so that the massage pressure portion achieves a softer massage effect.

[0199] Furthermore, if Fig.17 As shown, in some embodiments, the massage head 320 assembly further includes a telescopic device 324, which is disposed on the bearing shell 321 and includes a telescopic end connected to the hard convex body 322. In this way, the telescopic device 324 is used to drive the hard convex body 322 to expand and contract, so as to adjust the hardness of the massage head 320 assembly.

[0200] It should be noted that there can be many specific implementation methods of the telescope 324, including but not limited to a motor + screw nut assembly, a motor + rack and pinion assembly and other power sources 200 that provide telescopic power at equal intervals, and also a linear motor, a pneumatic lever or a hydraulic lever that can directly provide telescopic power.

[0201] In one example, the telescoping device 324 includes a motor 3241 and a cam 3242 drivingly connected to the motor 3241 . The cam 3242 is provided with a telescopic end and abuts against the hard convex body 322 .

[0202] like Fig.18As shown, in some embodiments, the first protective cavity 101 is provided with a notch 1011, a portion of the first bearing member 112 covers the notch 1011, a portion of the second bearing member 122 covers the notch 101, and is spaced apart from the first bearing member 112 to form an escape gap 1012 connected to the notch 1011, and the massage device 10 further includes a deformable elastic shielding member 180, which is disposed between the first bearing members 112 to shield the escape gap 1012. In this way, the elastic shielding member can shield the first protective cavity 101 by shielding the escape gap 1012, without affecting the relative rotation of the second bearing member 122.

[0203] Optionally, the elastic shielding member 180 includes a plurality of bending structures so as not to interfere with the relative rotation between the second supporting member 122 and the first supporting member 112 .

[0204] Optionally, the material of the elastic shielding member 180 includes silicone, rubber, elastic cloth, etc.

[0205] It should be noted that "adjustment of the massage range of the first massage component and the second massage component" should be understood in a broad sense, including changes in the massage trajectories of the first massage component and the second massage component, as well as changes thereof relative to the user's body.

[0206] Combination Fig.19 As shown, when the massage device 10 is used for shoulder and neck massage of a human body, the adjustment of the massage range of the first massage component 300 and the second massage component 400 can adjust the distance of the first massage component 300 and the second massage component 400 relative to the human spine, and / or adjust the neck up and down, and / or adjust the shoulders up and down. For example, when the user uses the massage device 10 for massage, if it is found that the massage position of the first massage component 300 and / or the second massage component 400 is far from the spine, and the uncomfortable position to be massaged is close to the spine. At this time, the angle between the first bearing component and the second bearing component can be reduced so that the first massage component 300 and the second massage component 400 move toward the spine, thereby being able to massage the uncomfortable position of the human body.
