Description

Clamping mechanism, massager clamping arm, deflection mechanism, massager movement and neck massager

[0001] This application claims priority to Chinese patent applications No. 202321715424.7 and No. 202321715520.1 filed on June 30, 2023, and the entire disclosures of these two applications are incorporated herein by reference. Technical Field

[0002] The present application relates to the technical field of massagers, and in particular to a clamping mechanism, a massager clamping arm, a deflection mechanism, a massager movement, and a neck massager. Background Art

[0003] A neck massager typically includes a wearable body, a movement, and a clamping arm. The inner side of the clamping arm is equipped with a cotton ball holder. The cotton ball holder includes a first housing that fits over the mounting shaft of the clamping arm and is pressed against the mounting shaft by a pressure block. To achieve rotation and position control of the cotton ball holder, the pressure block is typically equipped with a marble connected by a spring. Several locating holes are provided in the mounting portion of the first housing. When the marble rotates with the first housing to a locating hole, it snaps into place, locking the first housing.

[0004] The existing solutions have the following drawbacks:

[0005] First, it uses many parts, is complex to assemble, and is costly.

[0006] Second, the marble and the pressure block are connected by a spring, and the connection between the two is flexible. When the first shell rotates, the marble will react against the spring, and the spring will deform and stretch. The marble leaves the positioning hole slowly, and the user experience is poor.

[0007] Third, when the first shell is rotated, the spring is subjected to torsion in the circumferential direction. Every time the marble passes through a positioning hole, the spring needs to stretch and contract once and be twisted once, which makes the spring easily damaged.

[0008] In addition, a neck massager is used to massage the user's neck and includes a wearing body, clamping arms, a movement, and a massage head. The wearing body is used to surround the user's neck, and the two clamping arms are respectively connected to the two ends of the wearing body for clamping on the front side of the neck. The movement is assembled in the wearing body, and the massage head is located on the inner side of the wearing body. The movement includes a drive mechanism and an eccentric wheel, and the eccentric wheel is connected to the output gear of the drive mechanism via a connecting shaft. The other side of the eccentric wheel has a swing shaft, and the swing shaft is connected to a swing member. The swing member is connected to the massage head to drive the massage head to perform a swinging motion, thereby realizing a pinching and kneading massage function.

[0009] In the prior art, the eccentric wheel and the output gear are separated by a certain distance and then connected through a connecting shaft, which results in a large longitudinal dimension of the movement and a heavy structure of the movement, making it incompatible with miniaturized products.

[0010] Summary of the Invention

[0011] The purpose of this application is to overcome the shortcomings of the prior art. In the first aspect, this application provides a clamping mechanism, a massager clamping arm, and a neck massager. By providing a circle of locking grooves on the first shell, a locking protrusion is directly provided on the locking member. The first shell is locked by the cooperation between the locking protrusion and the locking groove. Fewer parts are required, the assembly method is simple, and costs are saved. When the user rotates the first shell, the locking protrusion remains stationary in the circumferential direction, and the locking groove can be quickly separated from the locking protrusion, with a fast disengagement speed, which improves the user experience. In the second aspect, this application provides a deflection mechanism, a massager movement, and a neck massager. The deflection drive member of the deflection mechanism is directly connected to the rotating wheel. Specifically, the drive member body of the deflection drive member is in direct contact and connection with the rotating wheel, and no connecting shaft is used for connection. There is no additional gap between the two, thereby shortening the longitudinal distance, which is conducive to realizing the lightweight and thinness of the massager movement, thereby adapting to miniaturized neck massagers.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0106] As shown in FIG. 1-8 , a clamping mechanism provided in one embodiment of the present application includes a clamping arm fixing portion 1 and a clamping arm clamping portion 2 pivotally assembled with the clamping arm fixing portion 1 .

[0107] The clamping arm holding portion 2 includes a first shell 21 having an assembly hole 211 , a flexible member 22 connected to the first shell 21 , and a locking member 23 connected to the clamping arm fixing portion 1 .

[0108] The first housing 21 is pivotally connected to the clamp arm fixing portion 1 .

[0109] The first housing 21 has a plurality of locking grooves 212 arranged in an annular shape on one side thereof facing the locking member 23 .

[0110] The locking member 23 has a locking protrusion 233 on a side facing the first housing 21 for engaging with the locking groove 212 .

[0111] When the locking protrusion 233 is in a mating state with any one of the locking grooves 212 , the clamping arm clamping portion 2 is in a rotationally locked state.

[0112] The clamping mechanism provided in the present application is used for the clamping arm of a massager, and is a component of the clamping arm of a massager.

[0113] The clamping mechanism includes a clamp arm fixing portion 1 and a clamp arm clamping portion 2. The clamp arm fixing portion 1 can be a boss, a shaft, a sleeve, etc. The clamp arm fixing portion 1 is used to connect to the clamp arm body 3 shown in Figures 10-11, and the clamp arm fixing portion 1 is connected to the inner side of the clamp arm body 3. The clamp arm fixing portion 1 can be connected to the clamp arm body 3 through a connecting mechanism, or the clamp arm fixing portion 1 can be integrally formed with the clamp arm body 3. The clamp arm clamping portion 2 is connected to one side of the clamp arm fixing portion 1, and is used to clamp on the front side of the user's neck.

[0114] The clamping arm clamping portion 2 includes a first shell 21, a flexible member 22 and a locking member 23. The first shell 21 provides support for the flexible member 22. The mounting surface of the first shell 21 has an assembly hole 211 for pivotally connecting with the clamping arm fixing portion 1 or the locking member 23. The first shell 21 can rotate relative to the clamping arm fixing portion 1 and the locking member 23. The flexible member 22 is a cotton ball, which is mounted on the first shell 21. The flexible member 22 is used to contact the user's skin and provide a comfortable feeling. The locking member 23 is connected to the clamping arm fixing portion 1 and is used to lock the first shell 21 from rotating.

[0115] In order to realize the locking function of the locking member 23 on the first housing 21, the present application adopts the following solution:

[0116] A plurality of locking grooves 212 are provided on a side of the first housing 21 facing the locking member 23 . The plurality of locking grooves 212 are arranged in a ring shape and surround the assembly hole 211 .

[0117] The locking member 23 has a locking protrusion 233 on the side facing the first housing 21. The locking protrusion 233 is configured to engage with the locking groove 212 to lock the first housing 21. The convex surface of the locking protrusion 233 is a curved surface, which facilitates the locking protrusion 233 to slide smoothly into and out of the locking groove 212.

[0118] When the locking protrusion 233 is engaged with any of the locking grooves 212, the clamp arm clamping portion 2 is in a rotationally locked state. When the user holds the first housing 21 and rotates the first housing 21, the locking protrusion 233 slides out of the current locking groove 212 and slides into the next locking groove 212, and so on, until the user rotates the clamp arm clamping portion 2 to the appropriate position.

[0119] In summary, the clamping mechanism provided herein includes a circle of locking grooves 212 on the first housing 21 and a locking protrusion 233 directly on the locking member 23. The locking protrusion 233 cooperates with the locking grooves 212 to lock the rotation of the first housing 21. This eliminates the need for pinballs and springs, requires fewer parts, simplifies assembly, and reduces costs. When the user rotates the first housing 21, the locking protrusion 233 remains stationary in the circumferential direction, allowing the locking groove 212 to quickly separate from the locking protrusion 233. This allows for a faster disengagement and improves the user experience.

[0120] In one embodiment, as shown in Figures 2 and 6-8, the locking member 23 includes a locking member body 231 and an elastic arm 232 connected to the locking member body 231. The locking member body 231 is connected to the clamp arm fixing portion 1. The locking protrusion 233 is provided on the side of the elastic arm 232 facing the first housing 21.

[0121] In this embodiment, the locking member 23 includes a locking member body 231 and an elastic arm 232. The elastic arm 232 is connected to one side of the locking member body 231. The locking member body 231 preferably adopts a circular structure. The elastic arm 232 preferably adopts a plastic arm or a plastic plate. The elastic arm 232 is preferably integrally formed with the locking member body 231, and the structural strength is high. The locking member body 231 is fixedly connected to the clamp arm fixing portion 1, and the locking protrusion 233 is provided at one end of the elastic arm 232 and is located on the side facing the first shell 21. Since the locking protrusion 233 is provided on the elastic arm 232, when the locking protrusion 233 slides into or out of the locking groove 212, the elastic arm 232 will undergo adaptive deformation, which is conducive to the locking protrusion 233 sliding smoothly into or out of the locking groove 212.

[0122] In one embodiment, as shown in FIG. 2 , a guide structure 24 is connected between the first housing 21 and the locking member 23 for guiding the first housing 21 to rotate.

[0142] In this embodiment, the clamp arm fixing portion 1 includes a fixing portion body 11 and a connecting shaft 12. The connecting shaft 12 is connected to one side of the fixing portion body 11, and an end surface 111 of the fixing portion body 11 surrounds the connecting shaft 12.

[0143] During assembly, the connecting shaft 12 passes through the assembly hole 211, and the locking member 23 contacts and connects with the connecting shaft 12, thereby forming a gap between the locking member 23 and the end surface 111, allowing the first housing 21 to be assembled and rotated. Specifically, the wall of the assembly hole 211 is assembled between the locking member 23 and the end surface 111 of the fixing portion body 11, allowing the first housing 21 to rotate relative to the locking member 23 and the clamp arm fixing portion 1.

[0144] To limit the number of rotations of the first housing 21, a hole wall protrusion 2111 is provided on the wall of the assembly hole 211, extending toward the center of the assembly hole 211. A connecting shaft protrusion 121 is provided on the circumferential surface of the connecting shaft 12, extending radially along the connecting shaft 12. The connecting shaft protrusion 121 is used to stop the hole wall protrusion 2111. When the first housing 21 rotates to a certain angle, the hole wall protrusion 2111 contacts and is blocked by the connecting shaft protrusion 121, preventing the first housing 21 from rotating further and limiting the rotation of the first housing 21 to no more than one rotation. The maximum angle that the first housing 21 can rotate is limited by parameters such as the size and central angle of the hole wall protrusion 2111 and the connecting shaft protrusion 121.

[0145] In one embodiment, as shown in Figures 4 and 6, two or more pipe columns 13 are spaced apart at the end of the clamp arm fixing portion 1, and correspondingly, two or more mounting holes 235 are provided on the locking member 23. The mounting holes 235 correspond one-to-one to the pipe columns 13 and are connected by a connector.

[0146] In this embodiment, two or more tubes 13 are provided at the end of the clamp arm fixing portion 1. These tubes 13 have connection holes for connection with the connector. Correspondingly, two or more mounting holes 235 are provided on the locking member 23. Each mounting hole 235 corresponds to a tube 13, and the connection is stabilized by the connector, preventing the locking member 23 from rotating.

[0147] The connection holes can be internal threaded holes, and the connection parts can be screws.

[0148] In one embodiment, as shown in FIG. 4 and FIG. 6 , two or more guide limit blocks 236 are correspondingly provided on the side of the locking member 23 facing the pipe column 13 , and the guide limit blocks 236 are arc-shaped.

[0149] The guide limit blocks 236 are matched with the pipe columns 13 in a one-to-one correspondence, and each pipe column 13 is located on the inner side of a guide limit block 236 .

[0150] In this embodiment, a guide stopper 236 is disposed around each mounting hole 235 and extends toward the pipe column 13. The guide stopper 236 is arc-shaped, preferably a semicircular arc, and its inner diameter is slightly larger than the outer diameter of the pipe column 13.

[0151] During assembly, the guide stopper 236 is aligned with the pipe column 13 to quickly push the locking member 23 into place so that the mounting hole 235 is aligned with the pipe column 13. After installation, the pipe column 13 is located inside the guide stopper 236 and also serves as a limiter.

[0152] In one embodiment, as shown in FIG2-3 , the clamping arm clamping portion 2 further includes an installation box 25 for installing a battery 26 or a counterweight, and the installation box 25 is detachably connected to the first housing 21 . The installation box 25 is enclosed in the flexible member 22 .

[0153] In this embodiment, a mounting box 25 is connected to one side of the first shell 21. The mounting box 25 is used to install a battery 26 or a counterweight to increase the weight of the clamping arm clamping part 2, so that the center of gravity of the neck massager moves forward, which is conducive to the clamping arm clamping part 2 being clamped forward on the front side of the user's neck.

[0154] The installation box 25 is connected to the first shell 21 by means of buckles, pins, etc., which facilitates assembly and disassembly.

[0155] In one embodiment, as shown in FIG. 9 , the box opening of the installation box 25 faces the first shell 21 , and an edge of the box opening is connected to an extension plate 251 extending toward the first shell 21 .

[0156] In this embodiment, an extension plate 251 is provided at the opening of the mounting box 25 to match the thickness of the battery 26 or the configuration object, thereby reducing the groove depth of the mounting box 25 and the depth of the mounting box 25 extending into the flexible member 22, thereby avoiding discomfort to the human body.

[0157] In one embodiment, as shown in FIG9 , at least one extension plate 251 is connected to a stop plate 252 for stopping the battery 26 or the counterweight, and the stop plate 252 extends toward the middle of the box opening to confine the battery 26 or the counterweight in the mounting box 25 through the stop plate 252, thereby improving the installation stability of the battery 26 or the counterweight.

[0158] The two mounting boxes 25 in the clamping parts 2 of the clamping arms on both sides of the neck massager can be equipped with batteries 26 at the same time, which not only provides a mounting location for the batteries 26 but also ensures that the mass of both sides is basically the same. Of course, it is also possible to install the batteries 26 in one mounting box 25 and a counterweight in the other mounting box 25, with the counterweight and the battery 26 having a mass that is roughly equal.

[0159] In one embodiment, as shown in FIG. 5 and FIG. 9 , a mounting plate 253 is connected to the outer circumference of the mounting box 25 , and the mounting plate 253 is connected to the first housing 21 via a snap-fit ​​structure for easy assembly and disassembly.

[0160] Specifically, a plurality of buckles 213 and a plurality of positioning posts 214 are provided at intervals on the first housing 21, and a plurality of clamping holes 2531 and a pair of positioning holes 2532 are provided at intervals on the mounting plate 253. The buckles 213 are engaged with the clamping holes 2531, and the positioning posts 214 are inserted into the positioning holes 2532.

[0161] During assembly, the positioning post 214 first cooperates with the positioning hole 2532 to provide a pre-positioning function, and then continues to press the first shell 21 or the mounting plate 253 so that the buckle 213 is locked into the locking hole 2531.

[0162] As shown in Figures 10-11, an embodiment of the present application provides a massager clamp arm, which includes a clamp arm body 3 and the clamping mechanism described in any of the aforementioned embodiments, and the clamp arm fixing portion 1 is connected to the clamp arm body 3.

[0163] The massager clamp arm provided in this application includes a clamp arm body 3 and the aforementioned clamping mechanism. For the structure, construction and working principle of the clamping mechanism, please refer to the above description of the clamping mechanism, which will not be repeated here.

[0164] The clamp arm fixing portion 1 is connected to the inner side of the clamp arm main body 3 . The clamp arm fixing portion 1 can be connected to the clamp arm main body 3 via a connecting mechanism, or the clamp arm fixing portion 1 can be integrally formed with the clamp arm main body 3 .

[0165] As shown in FIG12 , a neck massager provided in one embodiment of the present application includes a massager body 4 and the massager clamping arm described in the aforementioned embodiment, wherein the clamping arm body 3 is connected to the massager body 4 .

[0166] The neck massager provided in this application includes a massager body 4 and two massager arms. The massager body 4 includes a wearing body, a movement, and a massage head. The arm body 3 of each massager arm is connected to the wearing body of the massager body 4.

[0167] As shown in FIG13-14 , a yaw mechanism provided in one embodiment of the present application includes a rotating wheel 5 , a swinging member 6 , and a yaw driving member 7 for driving the swinging member 6 to perform yaw motion.

[0168] The yaw drive member 7 includes a drive member body 71 and a drive shaft 72 connected to the drive member body 71 and extending obliquely. The drive member body 71 is in contact with and connected to the rotating wheel 5, and the drive member body 71 rotates integrally with the rotating wheel 5. The swing member 6 is movably connected to the drive shaft 72.

[0169] The deflection mechanism provided in this application is used for the movement of a massager, and the deflection mechanism can drive the massage head to perform a deflection motion, thereby achieving a pinching and kneading massage.

[0170] The yaw mechanism provided herein includes a rotating wheel 5, an oscillating member 6, and an yaw drive member 7. The rotating wheel 5 can be a gear, which is connected to the drive transmission mechanism of the massager's movement, thereby driving the yaw drive member 7 to rotate. The oscillating member 6 is connected to the yaw drive member 7, which drives the yaw motion of the oscillating member 6. The oscillating member 6 is connected to the massage head, thereby driving the massage head to yaw motion. The oscillating member 6 can adopt a swinging rod, a swinging sleeve, or other structures.

[0171] The yaw drive member 7 includes a drive member body 71 and a drive shaft 72. The drive member body 71 can be in a circular, elliptical, square or other shape. The drive member body 71 can be a block structure. The drive member body 71 is in direct contact with and connected to the runner 5. The drive member body 71 can rotate integrally with the runner 5. The drive shaft 72 and the runner 5 are on opposite sides of the drive member body 71. The drive shaft 72 intersects with the center line of the runner 5. The drive shaft 72 is fixedly connected to the drive member body 71 and extends obliquely. The swing member 6 is movably connected to the drive shaft 72, and the drive shaft 72 can rotate relative to the swing member 6. When the yaw drive member 7 rotates with the runner 5, the deflected drive shaft 72 acts on the swing member 6, causing the swing member 6 to perform a yaw motion. For the specific method and motion trajectory of the specific yaw motion of the swing member 6, please refer to the introduction in the prior art, which will not be described in detail here.

[0172] The deflection mechanism provided in the present application has a deflection driving member 7 that is directly connected to the rotating wheel 5. Specifically, the driving member body 71 is in direct contact with and connected to the rotating wheel 5, and no connecting shaft is used. There is no additional gap between the two, thereby shortening the longitudinal distance, which is conducive to realizing the lightweight and thinning of the massager movement, thereby adapting to miniaturized neck massagers.

[0173] The longitudinal distance involved in this application refers to the distance along the axial direction of the wheel 5 as shown in FIG. 18 , or the distance along the thickness direction of the second shell 8 as shown in FIG. 22 .

[0174] In one embodiment, as shown in FIG. 15-16 , the driving member body 71 and the rotating wheel 5 are integrally formed; or, the driving member body 71 and the rotating wheel 5 are detachably connected.

[0175] In this embodiment, there are two assembly methods for the driving member body 71 and the rotating wheel 5 to meet different assembly requirements.

[0176] In the first assembly method, the driving member body 71 and the rotating wheel 5 are integrally formed, and the connection structure is stable.

[0177] In the second assembly method, the driving member body 71 and the rotating wheel 5 are connected in a detachable manner, which is convenient for disassembly and replacement of accessories according to actual application sites.

[0178] In one embodiment, as shown in FIG16-17 , a first slot 52 is provided on the driving member body 71 / rotating wheel 5 , and a clamping block 713 is provided on the rotating wheel 5 / driving member body 71 . The clamping block 713 is engaged with the first slot 52 .

[0179] As a specific solution to the second assembly method described above, in this embodiment, the first engaging groove 52 can be provided on the driver body 71 or the rotating wheel 5, while the engaging block 713 can be provided on the rotating wheel 5 or the driver body 71. During assembly, the engaging block 713 is engaged with the first engaging groove 52, and the top surface of the driver body 71 contacts the bottom surface of the rotating wheel 5.

[0180] In one embodiment, a second slot is formed on a side of the rotating wheel 5 facing the driving member body 71 , and the driving member body 71 is engaged with the second slot.

[0181] As another specific solution of the second assembly method described above, in this embodiment, a second slot is provided on the bottom surface of the rotating wheel 5, and the driving member body 71 is a block, the upper end of which is engaged with the second slot, and the top surface of the driving member body 71 enters the second slot, further shortening the longitudinal dimension between the rotating wheel 5 and the driving member body 71, which is more conducive to thinning design. When the driving member body 71 is a block, the part of the driving member body 71 that serves as the block is a non-rotating body, which rotates synchronously with the rotating wheel 5. Preferably, the second slot can be a non-circular special-shaped slot, and the end of the driving member body 71 engaged with the second slot is also a non-circular special-shaped engaging end, which plays an anti-rotation role.

[0182] In one embodiment, as shown in FIG. 14-16 and FIG. 21 , the bottom surface of the driving member body 71 facing the swing member 6 has a main body inclined surface 711 , and the driving shaft 72 is connected to the main body inclined surface 711 .

[0183] The swinging member 6 has a guide hole 61 for assembling the driving shaft 72 , and the driving shaft 72 cooperates with the guide hole 61 .

[0184] One end of the swinging member 6 facing the main body inclined surface 711 has a flat surface portion 62 , and the flat surface portion 62 is in contact with the main body inclined surface 711 .

[0185] In this embodiment, the bottom surface of the driving member body 71 is the main body inclined surface 711. The driving shaft 72 is connected to the main body inclined surface 711. Preferably, the driving shaft 72 is perpendicular to the main body inclined surface 711 so that the inclination angle of the driving shaft 72 can be controlled according to the inclination angle of the main body inclined surface 711.

[0186] The swing member 6 utilizes a swing sleeve structure, having a guide hole 61 into which a drive shaft 72 is inserted, allowing the drive shaft 72 to rotate within the guide hole 61. The top surface of the swing member 6 has a flat surface 62, which contacts or abuts against an inclined surface 711 of the main body. When the driver body 71 and drive shaft 72 rotate as one, the inclined drive shaft 72 acts on the wall of the guide hole 61, while the inclined surface 711 of the main body acts on the flat surface 62, driving the swing member 6 into a yaw motion.

[0187] As needed, a spherical crown 64 or an arc-shaped convex portion may be provided on the upper portion of the swing member 6 to cooperate with a limit member or a supporting structure so that the swing of the swing member 6 is supported and limited to a certain extent.

[0188] In one embodiment, as shown in FIG18 , the minimum distance between the main body inclined surface 711 and the rotating wheel 5 is greater than 2 mm. Specifically, the distance H between the lowest point A of the main body inclined surface 711 and the surface of the rotating wheel 5 facing the driving member main body 71 is greater than 2 mm. This prevents contact or interference between the swinging member 6 and the rotating wheel 5 during movement. Interference between the swinging member 6 and the rotating wheel 5 can adversely affect the movement of both. Contact between the two can cause wear, affecting their structural strength, and can also lead to transmission failure due to a jam between the swinging member 6 and the rotating wheel 5.

[0189] In one embodiment, as shown in Figures 15-16 and 19-20, a blind hole 712 is provided in the driving member body 71, the opening of the blind hole 712 is located on the inclined surface 711 of the main body, and a support member 73 is provided in the blind hole 712. One end of the driving shaft 72 is inserted into the blind hole 712 and cooperates with the support member 73.

[0190] During the movement of the driving shaft 72 , pressure is generated on the bottom and wall of the blind hole 712 , which may easily cause local deformation of the blind hole 712 and affect the connection stability.

[0191] In this embodiment, a support member 73 is provided in the blind hole 712 , so that the support member 73 and the driving shaft 72 play a role in protecting the driving member body 71 .

[0192] As shown in FIG19 , one configuration of the support member 73 is as follows: the support member 73 is a protrusion 731 provided at the bottom of the blind hole 712. The protrusion 731 can be integrally formed with the driver body 71, or the protrusion 731 can be embedded in the bottom of the hole. The top end of the drive shaft 72 has an assembly groove 721. The top end of the drive shaft 72 is inserted into the blind hole 712, and the protrusion 731 fits in the assembly groove 721 to assemble the drive shaft 72 with the driver body 71. The protrusion 731 supports and connects the drive shaft 72, preventing the top end of the drive shaft 72 from directly squeezing the driver body 71 during the yaw motion, thereby causing the driver body 71 to deform and affect the connection reliability.

[0193] As shown in FIG20 , another configuration of the support member 73 is as follows: the support member 73 is a sheath 732 embedded in the blind hole 712 , and the top end of the drive shaft 72 is inserted into the sheath 732 . The drive shaft 72 does not directly contact the drive member body 71 .

[0194] Generally, the hardness of the driving member body 71 is less than the hardness of the driving shaft 72. If the driving shaft 72 is inserted into the blind hole 712 and directly contacts the hole wall, the hole wall of the blind hole 712 will be squeezed during the movement of the driving shaft 72 relative to the blind hole 712, causing the blind hole 712 to deform, which in turn affects the stability of the connection between the driving shaft 72 and the driving member body 71.

[0195] The walls of blind hole 712 are reinforced by a sheath 732. Support member 73 can be made of the same material as drive shaft 72 or another material with higher hardness. The hardness of support member 73 is higher than the hardness of the walls of blind hole 712. Sheath 732 is embedded in blind hole 712, while drive shaft 72 is inserted into sheath 732. Drive shaft 72 moves relative to sheath 732, which is not easily deformed by compression, thus ensuring a stable connection between drive shaft 72 and driver body 71.

[0196] In one embodiment, as shown in Figures 13-14 and 21, at least one side of the swing member 6 has a guide protrusion 63 for cooperating with the second guide groove 102 of the limiting member 6 described below to provide a certain guiding and limiting effect for the movement of the swing member 6.

[0197] As shown in Figures 22-26, a massager movement provided in one embodiment of the present application includes a second shell 8, a drive transmission mechanism 9 installed in the second shell 8, and the deflection mechanism described in any of the aforementioned embodiments.

[0198] The driving transmission mechanism 9 includes a reduction gear set 92 .

[0199] A first gear groove 84 and a second gear groove 85 are provided on the inner surface of the second housing 8 . The groove depth of the first gear groove 84 is greater than the groove depth of the second gear groove 85 .

[0200] The reduction gear set 92 is installed in the first gear groove 84 , and the output end gear 924 of the reduction gear set 92 is located on a side close to the second gear groove 85 .

[0201] The rotating wheel 5 is installed in the second gear groove 85 and meshes with the output end gear 924.

[0202] The massager provided in this application includes a second housing 8, a drive transmission mechanism 9 and the aforementioned deflection mechanism. For the structure, construction and working principle of the deflection mechanism, please refer to the previous description of the deflection mechanism, which will not be repeated here.

[0203] The second shell 8 includes an upper second shell 81 and a lower second shell 82 . The upper second shell 81 and the lower second shell 82 are connected to form a cavity therebetween. The drive transmission mechanism 9 and the yaw mechanism are installed in the cavity of the second shell 8 .

[0204] The drive transmission mechanism 9 includes a drive motor 91 and a reduction gear set 92. The output end of the drive motor 91 is connected to a worm 911.

[0205] The reduction gear set 92 includes an input gear 921 meshing with the worm 911, a first transmission gear 922 coaxially arranged with the input gear 921, a second transmission gear 923 meshing with the first transmission gear 922, and an output gear 924 coaxially arranged with the second transmission gear 923. The input gear 921 has a larger diameter than the first transmission gear 922, which is smaller than the second transmission gear 923. The second transmission gear 923 has a larger diameter than the output gear 924, which is smaller than the wheel 5, thereby achieving a reduction transmission function. The first transmission gear 922 is located above the input gear 921, and the second transmission gear 923 is located above the output gear 924.

[0206] A first gear groove 84 and a second gear groove 85 are provided on the inner surface of the second housing 8. Specifically, the first gear groove 84 and the second gear groove 85 are located on the bottom surface of the top plate of the upper second housing 81. The first gear groove 84 is deeper than the second gear groove 85, forming a step between the first and second gear grooves 84 and 85. The reduction gear assembly 92 is mounted in the first gear groove 84, with the output gear 924 positioned adjacent to the second gear groove 85. The runner 5 is mounted in the second gear groove 85 and meshes with the output gear 924 for transmission.

[0207] In this embodiment, the bottom of the second gear groove 85 is located between the notch and the bottom of the first gear groove 84. The second gear groove 85 is relatively shallow, and is used to accommodate a single rotating wheel 5. The first gear groove 84 is relatively deep, and is used to accommodate the thicker reduction gear set 92. By forming a step difference between the first gear groove 84 and the second gear groove 85, the reduction gear set 92 is brought as close as possible to the top surface of the top plate of the upper second housing 81, while ensuring that the rotating wheel 5 and the output end gear 924 are meshed. This also helps to reduce the longitudinal dimension of the movement, facilitates the lightweight and thinning of the massager movement, and thus adapts to miniaturized neck massagers.

[0208] As needed, a through hole can be opened at a corresponding position of the second shell 8 for the swing member 6 to pass through so as to be connected to the massage head.

[0209] In one embodiment, as shown in Figures 22-231 and Figures 27-29, the second shell 8 is provided with a shell through hole 83, and a limiting sleeve 10 is assembled in the shell through hole 83. One end of the limiting sleeve 10 is located on the outside of the second shell 8, and the swinging member 6 passes through the limiting sleeve 10.

[0210] In this embodiment, a limiting sleeve 10 is installed in the housing through hole 83 of the second housing 8. The housing through hole 83 is preferably provided on the bottom plate of the lower second housing 82. The limiting sleeve 10 is used to provide a limit for the swing member 6.

[0211] The limiting sleeve 10 includes a limiting groove 101, the bottom plate of which has a through-hole 1011. The spherical crown 64 or curved protrusion of the swinging member 6 fits within the limiting groove 101 and can move relative to the walls of the limiting groove 101. The main body of the swinging member 6 extends through the through-hole 1011 to connect with the massage head. As the swinging member 6 swings, its spherical crown 64 or curved protrusion swings accordingly within the limiting groove 101, providing support for the swinging of the swinging member 6. The swinging amplitude of the swinging member 6 is limited by the walls of the through-hole 1011 or the walls of the limiting groove 101.

[0212] In this embodiment, one end of the limit sleeve 10 is assembled in the shell through hole 83 and at least partially enters the cavity of the second shell 8, rather than directly extending from the bottom surface of the lower second shell 82, which is beneficial to further shorten the longitudinal dimension of the massager movement.

[0213] In one embodiment, the limiting sleeve 10 is provided separately from the second housing 8. The limiting sleeve 10 and the second housing 8 can be made of different materials, which facilitates the selection of the material of the limiting sleeve 10 to meet different needs. The surface of the limiting sleeve 10 can be set to be relatively smooth, while the surface of the second housing 8 can be set to be relatively rough. When the limiting member 6 and the second housing 8 contact or collide, the different smoothness of the two reduces the noise generated. When the limiting member 6 and the second housing 8 contact, the smooth surface of the limiting sleeve 10 reduces the resistance between the limiting member 6 and the second housing 8, thereby reducing wear.

[0214] In one embodiment, as shown in Figures 28-29, a limiting step 831 is provided on the hole wall of the shell through hole 83, and the limiting sleeve 10 has a limiting flange 103, which is installed on the limiting step 831.

[0215] In this embodiment, a circle of limiting steps 831 is provided on the inner surface of the hole wall of the housing through hole 83, thereby forming a slot. The edge of the limiting sleeve 10 has a limiting flange 103 for locking into the slot formed by the limiting steps 831.

[0216] Through the cooperation between the limiting flange 103 and the limiting step 831 , one end of the limiting sleeve 10 can be limited inside the second shell 8 , which facilitates installation and simplifies the installation process.

[0217] In one embodiment, as shown in Figures 21-22 and Figure 297, the limiting sleeve 10 has a second guide groove 102 for cooperating with the guide protrusion 63 of the swinging member 6, and the guide protrusion 63 is engaged in the second guide groove 102.

[0218] In this embodiment, a guide protrusion 63 is disposed on the side of the swinging member 6. Preferably, one guide protrusion 63 is disposed on each of two opposing sides of the swinging member 6. The limiting sleeve 10 has a second guide groove 102 on at least one side of the limiting groove 101. Preferably, one second guide groove 102 is disposed on each of two opposing sides of the limiting groove 101.

[0219] The guide protrusion 63 is assembled in the second guide groove 102 and can slide relative to the groove wall of the second guide groove 102, so that the guide protrusion 63 can only swing in the second guide groove 102, playing a limiting and guiding role.

[0220] In one embodiment, as shown in FIG16 , a gasket 53 is provided between the limiting sleeve 10 and the rotating wheel 5. The rotating wheel 5 can move relative to the limiting sleeve 10. The gasket 53 can be added to the bottom surface of the rotating wheel 5 or to the top surface of the limiting sleeve 10 to prevent direct contact or wear between the limiting sleeve 10 and the rotating wheel 5.

[0221] As shown in FIG30 , a neck massager provided in one embodiment of the present application includes the massager movement of any of the aforementioned embodiments.

[0222] Specifically, the neck massager includes a wearing body 100, a massage head 200, a clamping arm 300 and the aforementioned massager movement. For the structure, construction and working principle of the massager movement, please refer to the above description of the massager movement, which will not be repeated here.

[0223] The wearing body 100 is in a non-closed ring shape, with a clamping arm 300 connected to each end of the wearing body 100 , and the massage head 200 is located inside the wearing body 100 .

[0224] The massager movement is installed in the wearing body 100, and the swing member 6 extends out of the wearing body 100 and is connected to the massage head 200.

[0225] Since the massager movement provided in the present application has a reduced longitudinal dimension, the thickness of the wearing body 100 can be reduced accordingly, thereby reducing the longitudinal dimension of the neck massager.

[0226] It should be noted that the neck massager in this embodiment can be the same as the neck massager in the previous embodiment. The wearing body 100 in this embodiment can be the wearing body of the massager body 4 in the previous embodiment. The clamping arm 300 in this embodiment can be the clamping arm of the massager in the previous embodiment.

[0227] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0228] The above are merely the principles and preferred embodiments of the present application. It should be noted that, for those skilled in the art, implementation methods obtained by appropriately combining the technical solutions disclosed in different embodiments are also included in the technical scope of the present application. Based on the principles of the present application, several other variations can be made and should also be considered as the scope of protection of the present application.
