Description

Technical Field

[0001] The present invention relates to the field of massage equipment, and in particular to a freely controllable massage movement. Background Art

[0002] A massager is a carefully designed massage device designed to stimulate blood circulation and relieve muscle fatigue through a series of movements, including rotation, vibration, and tapping. For those who maintain a fixed posture or sit for long periods of time, this device is undoubtedly a very useful auxiliary tool, helping to alleviate the discomfort caused by these unhealthy habits.

[0003] Common massage mechanisms on the market primarily rely on the rotation of massage heads to massage the corresponding body parts. Combined with a pendulum-shaped design, this can simulate a kneading effect, enriching the massage experience. However, existing massage heads typically operate in conjunction with each other, reducing controllability. Some massage heads, constrained by internal space, are limited to massage protrusions, meaning they cannot rotate independently and rely solely on the movement of connected components, resulting in poor massage results.

[0004] For example, a shoulder massage movement with patent application number CN201710713462.1 drives the second massage head to rotate through the eccentric shaft of the kneading gear, and the first massage head performs a compound motion of left and right swinging and forward and backward motion under the action of the eccentric shaft and the limit pin as the fulcrum. When the first massage head, the limit pin and the second massage head are in a straight line, the distance between the first massage head and the second massage head is the maximum or minimum distance, and a pinching effect is achieved between the two massage heads, so that the massage head group can simultaneously satisfy the massage and kneading of the shoulders. There will also be a distance change between the two groups of reciprocating first massage heads to achieve a kneading effect. This patent drives the two massage heads to perform a complex compound motion through a deflection wheel. However, although the first massage head in the above structure can achieve a large range of reciprocating swing and increase the massage area, the first massage head itself does not have the function of rotatable massage, which greatly reduces the massage effect. The user cannot freely control the first massage head to stop at a fixed point for massage and can only perform repeated massage according to a preset trajectory, which cannot meet the user's free adjustment needs. On the other hand, since the first massage head has a large range of motion, it is also impossible to set a separate drive component for it in the existing technology. It is understandable that the drive component usually needs to be installed in a fixed position to work. Summary of the Invention

[0051] Example:

[0052] like Figure 1 and Figure 2As shown, a free-control massage movement includes a first drive motor 130 disposed in a housing 100. The first drive motor 130 is the core component that drives the massage head 280 to rotate; the first worm 131 of the first drive motor 130 is connected to a multifunctional movable component 200 at both ends; it can be understood that the first worm 131 is also the output shaft of the first drive motor 130; both ends of the first worm 131 extend out of the first drive motor 130; the first worm 131 can be an integral structure with the output shaft of the first drive motor 130, or can be a first worm 131 formed by a worm component sleeved on the output shaft of the first drive motor 130. Figure 3 As shown, the first worm 131 and the output shaft of the first drive motor 130 are an integrated structure.

[0053] In one embodiment of the present invention, the multifunctional movable component 200 is movably connected to the shell 100; the shell 100 can be understood as a limiting shell 100 structure arranged outside the multifunctional movable component 200, which can limit the moving position of the multifunctional movable component 200 on the one hand, and support the installation of the multifunctional movable component 200; the shell 100 has a cavity structure for accommodating the multifunctional movable component 200; in one embodiment, the shell 100 is composed of an upper shell 110 and a lower shell 120 fixedly connected, and the upper shell 110 and the lower shell 120 are fixedly connected by a number of fixing screws, which is convenient for disassembly and installation of the multifunctional movable component 200 and other internal components.

[0054] In one embodiment of the present invention, a second drive component 300 is provided in the shell 100 for driving the multifunctional movable component 200 to rotate around one end close to the first drive motor 130; it can be understood that the multifunctional movable component 200 forms a rotating connection portion at one end close to the first drive motor 130, and the rotating connection portion generally cooperates with the shell 100; in one embodiment, the rotating connection portion is a rotating protrusion 2122 formed on the multifunctional movable component 200; the shell 100 is provided with a rotating groove 121 that cooperates with the rotating protrusion 2122; so as to form a rotational connection between the multifunctional movable component 200 and the shell 100.

[0055] In one embodiment of the present invention, the second drive assembly 300 includes a second drive motor 310 provided on one side of the first drive motor 130; a second worm gear 321 is engaged with a second worm 311 of the second drive motor 310; it is understood that the second worm 311 is also the output shaft of the second drive motor 310; one end of the second worm 311 extends out of the second drive motor 310; the second worm 311 can be an integral structure with the output shaft of the second drive motor 310, or can be a second worm 311 formed by a worm component sleeved on the output shaft of the second drive motor 310. Figure 3As shown, the second worm 311 is formed by a worm component sleeved on the output shaft of the second drive motor 310. The worm component can be understood as a worm component with a connecting hole connected to the output shaft in the middle, and a worm structure is formed on the outside.

[0056] In one embodiment of the present invention, the second worm gear 321 is prevented from rotating and is arranged on the second transmission shaft 320; the second transmission shaft 320 forms a second worm portion 322 at one end away from the second worm gear 321; it can be understood that the second worm portion 322 can form an integral structure with the second transmission shaft 320, or be a worm component sleeved on the second transmission shaft 320; an adjustment seat 330 is engaged on each side of the second worm portion 322; the adjustment seat 330 is engaged with the second worm portion 322 through a local adjustment tooth 331; it can be understood that the local adjustment tooth 331 is an arc-shaped rack, and the rack is the tooth shape of the worm gear. The use of the local adjustment tooth 331 is equivalent to a small part of the complete worm gear structure, which can alleviate the space occupied in the housing 100 and effectively reduce the occupied volume; the end of the adjustment seat 330 away from the local adjustment tooth 331 is connected to the multi-functional movable component 200, usually a fixed connection.

[0057] In one embodiment, if Figure 7 As shown, the end of the adjustment seat 330 connected to the multifunctional movable component 200 is rectangular, and correspondingly, by setting a rectangular groove on the multifunctional movable component 200, the adjustment seat 330 can be effectively limited and fixed, that is, the rectangular groove structure can be used to achieve limited cooperation to achieve the common movement of the adjustment seat 330 and the multifunctional movable component 200; the curvature center of the local adjustment tooth 331 is located on the rotation axis of the multifunctional movable component 200; it can be understood that the curvature center of the local adjustment tooth 331 is located on the central axis of the rotating protrusion 2122, that is, the rotation of the local adjustment tooth 331 is carried out around the central axis of the rotating protrusion 2122, thereby ensuring the meshing state of the local adjustment tooth 331 and the second worm part 322, and at the same time ensuring the smooth rotation of the multifunctional movable component 200. The multifunctional movable component 200 can be understood as Figure 2 Based on the above description, the upper middle cover 211 and the lower middle cover 212 and the components inside them are connected in a limited manner with the adjustment seat 330 and the multifunctional movable component 200. The rotation centers of the adjustment seat 330 and the multifunctional movable component 200 are both the central axis of the rotating protrusion 2122. When the adjustment seat 330 rotates under the drive of the second drive motor 310, the multifunctional movable component 200 can rotate around the central axis of the rotating protrusion 2122.

[0058] In one embodiment of the present invention, the second drive assembly 300 can also be driven to rotate by a general gear assembly. The gear assembly is a plurality of meshing spur gears, one of which is connected to the output shaft of the drive motor, and the rotation stop on the rotating protrusion 2122 is connected to a spur gear meshing with the spur gear on the output shaft of the drive motor, thereby realizing the rotation drive of the multifunctional movable assembly 200. In the present invention, it is preferred to adopt the structure of the adjustment seat 330 in the previous embodiment for driving, which can better control the thickness size of the massage movement and effectively reduce the volume. It can be understood that the adjustment seat 330 is only a part of the conventional gear, which effectively reduces the volume compared to the complete gear structure; in one embodiment, the second drive assembly 300 can also include two second drive motors 310, which respectively control the two multifunctional movable assemblies 200 to rotate through the two second drive motors 310, and the transmission can be realized by the commonly used gear connection or worm gear in this field.

[0059] In one embodiment of the present invention, the second transmission shaft 320 is disposed perpendicular to the first worm 131 .

[0060] In one embodiment of the present invention, the second driving motor 310 is disposed on a side of the first driving motor 130 away from the first connecting gear 260 , which can effectively avoid the location of the third driving assembly 400 and reasonably utilize the internal space of the housing 100 .

[0061] In one embodiment of the present invention, a first transmission shaft 230 is provided in the multifunctional movable component 200; one end of the first transmission shaft 230 is transmission-connected to the first worm 131, and the other end is transmission-connected to the massage head 280; the transmission connection can be understood as, the rotation of the first worm 131 can drive the rotation of the first transmission shaft 230, and the rotation of the first transmission shaft 230 can drive the rotation of the massage head 280.

[0062] In one embodiment of the present invention, the rotation axis of the massage head 280 is set at an angle to the first transmission shaft 230; the angle setting ensures that the massage head 280 is located above the housing 100, that is, the massage head 280 is set in the thickness direction of the housing 100 to ensure the massage effect; the thickness direction is as shown in FIG. Figure 1In one embodiment, the rotation axis of the massage head 280 is perpendicular to the first transmission shaft 230. The massage head 280 is configured to move axially along the first transmission shaft 230 to increase the range of motion of the massage head 280. A first connecting gear 260 is provided on the end of the multifunctional movable component 200 near the first drive motor 130. An eccentric shaft 261 is provided on the first connecting gear 260. A connecting arm 270 is rotatably connected to the eccentric shaft 261. The end of the connecting arm 270 away from the eccentric shaft 261 is connected to the massage head 280. A third driving component 400 is provided within the housing 100 to drive the first connecting gear 260 to rotate. After the first connecting gear 260 rotates, the eccentric shaft 261 can drive the connecting arm 270 to reciprocate, thereby driving the massage head 280 to move axially along the first transmission shaft 230.

[0063] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the first transmission shaft 230 is fixedly connected to the second bevel gear 231; the second bevel gear 231 is meshed with the first bevel gear 241; the first bevel gear 241 is provided with a first worm gear 240 that is coaxial with the first bevel gear 241 and rotates synchronously with it at one end of the first bevel gear 241 away from the second bevel gear 231; it can be understood that the first worm gear 240 and the first bevel gear 241 can be an integral structure or a split structure; when the first worm gear 240 and the first bevel gear 241 are split structures, a first center axis 242 can be set in the middle; the first center axis 242 is simultaneously fixedly connected to the first bevel gear 241 and the first worm gear 240, thereby achieving synchronous rotation of the two; when the first worm gear 240 and the first bevel gear 241 are an integral structure, a first center axis 242 can also be set in the middle thereof; in one embodiment, the first worm gear 240 is fixedly connected to the first bevel gear 241, and coaxial and synchronous rotation can also be achieved.

[0064] In one embodiment of the present invention, the first worm gear 240 cooperates with the first worm 131; when the first drive motor 130 drives the first worm 131 to rotate, the first worm 131 can drive the first worm gear 240 to rotate, and the rotation of the first worm gear 240 drives the first bevel gear 241 to rotate, and the rotation of the first bevel gear 241 drives the second bevel gear 231 to rotate, and the rotation of the second bevel gear 231 drives the first transmission shaft 230 to rotate, thereby forming a transmission connection between the first transmission shaft 230 and the first worm 131.

[0065] In one embodiment of the present invention, a third bevel gear 232 is fixedly connected to the first transmission shaft 230 in a rotation-stopping and sliding manner; in one embodiment, the connection portion between the first transmission shaft 230 and the third bevel gear 232 is a flat shaft, thereby achieving the effect of a rotation-stopping and sliding connection between the third bevel gear 232 and the first transmission shaft 230; the flat shaft can be understood as a structure in which a part / two opposite parts are cut off axially on a cylinder to form a plane / or two planes; in one embodiment, the first transmission shaft 230 can also be set as a polygonal shaft, which can also achieve a rotation-stopping and sliding connection structure with the third bevel gear 232; the polygonal shaft can be a triangular shaft, a quadrilateral shaft, a pentagonal shaft, a hexagonal shaft, etc.

[0066] like Figure 3 As shown, in one embodiment of the present invention, the third bevel gear 232 is meshed with a fourth bevel gear 250; the second central axis 251 in the middle of the fourth bevel gear 250 is connected to the massage head 280 for rotation prevention; the connecting arm 270 is sleeved on the second central axis 251 and connected to the massage head 280; it can be understood that the connecting arm 270 is sleeved on the second central axis 251, and the connecting arm 270 can rotate relative to the second central axis 251. The upper end of the second central axis 251 extends out of the connecting arm 270 and is connected to the massage head 280 for rotation prevention. The end of the second central axis 251 extending out of the connecting arm 270 can be set as a flat head (such as Figure 3 The structure of the upper portion of the second central shaft 251 in the middle is shown in FIG. 2 , that is, the connecting arm 270 is sleeved on the second central shaft 251 and indirectly connected to the massage head 280 via the second central shaft 251. In this structure, the connecting arm 270 can only drive the position of the massage head 280 to move but will not affect the rotation of the massage head 280. The connecting arm 270 is provided with a second clearance hole 272 that cooperates with the second central shaft 251 and an eccentric shaft connecting portion 271 that is rotatably connected to the eccentric shaft 261. When the first connecting gear 260 rotates, the eccentric shaft 261 can rotate eccentrically, thereby driving the connecting arm 270 to move. The connecting arm 270 can drive the movable seat 220 and the massage head 280 to move axially along the first transmission shaft 230 through the second central shaft 251. Since the drive of the first connecting gear 260 is independent, the movement position of the massage head 280 along the direction of the first transmission shaft 230 can be independently controlled, so that the massage head 280 can massage at any point.

[0067] like Figure 6As shown, in one embodiment of the present invention, a movable seat 220 is provided outside the third bevel gear 232 and the fourth bevel gear 250; the movable seat 220 clamps the third bevel gear 232 and the fourth bevel gear 250, so that the third bevel gear 232 can move along the axial direction of the first transmission shaft 230 while also being able to transmit and connect the massage head 280, ensuring the continuous engagement of the third bevel gear 232 and the fourth bevel gear 250. It can be understood that under the clamping action of the movable seat 220, the third bevel gear 232 and the fourth bevel gear 250 can always maintain an engaged state, and the third bevel gear 232 is fixed and slidably connected to the first transmission shaft 230. Generally, the first transmission shaft 230 is a flat shaft, and the flat shaft can be understood as a structure in which a part / two opposite parts are cut off axially on a cylinder to form a plane / or two planes, thereby limiting the rotation of the third bevel gear 232 relative to the first transmission shaft 230, and ensuring that the first transmission shaft 230 transmits torque to the third bevel gear 232. At the same time, there is no other limiting structure between the third bevel gear 232 and the first transmission shaft 230, and the third bevel gear 232 can move along the axial direction of the first transmission shaft 230.

[0068] In one embodiment, the movable seat 220 is connected to the eccentric shaft 261 on the first connecting gear 260 through the connecting arm 270. When the first connecting gear 260 rotates, the change in the position of the eccentric shaft 261 will act on the movable seat 220 through the connecting arm 270, so that the movable seat 220 approaches or moves away from the rotation center of the first connecting gear 260, and the movable seat 220 is limited by the slide groove 2111, so that the movable seat 220 can only move along the length direction of the slide groove 2111 (that is, the axial direction of the first transmission shaft 230).

[0069] In one embodiment, the connecting arm 270 can directly cooperate with the limiting protrusion 2211. The connecting arm 270 is sleeved on the limiting protrusion 2211. The connecting arm 270 can rotate relative to the limiting protrusion 2211. The movement of the connecting arm 270 can only act on the movable seat 220 to move along the length direction of the slide groove 2111 (that is, the axial direction of the first transmission shaft 230); the second central shaft 251 passes through the first clearance hole 2212 and is connected to the fourth bevel gear 250 for rotation prevention. The other end of the second central shaft 251 is connected to the massage head 280 for rotation prevention. When the movable seat 220 moves along the axial direction of the first transmission shaft 230 under the drive of the connecting arm 270, it can drive the synchronous movement of the massage head 280. The rotation prevention connection is the flat shaft structure mentioned above, and can also adopt a key connection or a pin connection, which are commonly used structures in this field. Figure 3 The top of the second central axis 251 is a flat axis structure.

[0070] In one embodiment, the connecting arm 270 can also be directly connected to the second central shaft 251. The connecting arm 270 is sleeved on the second central shaft 251. The connecting arm 270 can rotate relative to the second central shaft 251. The second central shaft 251 passes through the first clearance hole 2212 and is connected to the fourth bevel gear 250 for rotation prevention. The other end of the second central shaft 251 is connected to the massage head 280 for rotation prevention. The movement of the connecting arm 270 can drive the movable seat 220, the second central shaft 251, and the massage head 280 to approach or move away from the rotation center of the first connecting gear 260, and the movable seat 220 is limited by the slide groove 2111, so that the movable seat 220 can only move along the length direction of the slide groove 2111 (that is, the axial direction of the first transmission shaft 230), thereby also limiting the movement of the massage head 280.

[0071] In one embodiment, the connecting arm 270 is a structural component for transmitting force and needs to have a certain degree of rigidity. It is preferably made of a rigid material, which may be plastic, metal, or polymer material.

[0072] In one embodiment, the movement of the movable seat 220 further drives the third bevel gear 232 and the fourth bevel gear 250 to move synchronously along the axial direction of the first transmission shaft 230. In one embodiment, the movable seat 220 clamps the third bevel gear 232 to form a movable connection, and the upper movable seat 221 and the lower movable seat 222 are both provided with a semicircular clamping portion 2224 arranged opposite to each other, and the third bevel gear 232 is provided with a connecting portion 2321 that cooperates with the clamping portion 2224, thereby achieving a movable connection between the third bevel gear 232 and the movable seat 220; Figure 5 As shown, the connecting portion 2321 is cylindrical, and a shift ring 2322 is further provided on the side of the connecting portion 2321 away from the third bevel gear 232. The shift ring 2322 and the end of the third bevel gear 232 and the clamping portion 2224 are limited, so that the movable seat 220 can drive the third bevel gear 232 to move axially along the first transmission shaft 230, and the third bevel gear 232 can also rotate along the first transmission shaft 230.

[0073] In one embodiment, the shift ring 2322 may be provided on each side of the connecting portion 2321 , thereby preventing the clamping portion 2224 from directly contacting the end of the third bevel gear 232 and reducing the rotational resistance of the third bevel gear 232 .

[0074] In one embodiment, the connecting portion 2321 and the shift ring 2322 may not be provided on the third bevel gear 232. The clamping portion 2224 directly cooperates with the first transmission shaft 230 and is limited to the side of the third bevel gear 232 away from the fourth bevel gear 250. Since the fourth bevel gear 250 is clamped between the support portion 2222 and the upper movable seat 221, the movement of the movable seat 220 will directly drive the movement of the fourth bevel gear 250. One side of the third bevel gear 232 is limited by the clamping portion 2224, and the other side is engaged and limited with the fourth bevel gear 250, so that the third bevel gear 232 can also follow the movable seat 220 along the axial movement of the first transmission shaft 230.

[0075] In one embodiment of the present invention, the multifunctional movable component 200 includes a first transmission shaft 230 arranged in the cover body 210; the first worm gear 240, the first bevel gear 241, the second bevel gear 231, the third bevel gear 232, and the fourth bevel gear 250 are all located in the internal cavity of the cover body 210; the movable seat 220 is slidingly connected to the cover body 210; the cover body 210 is provided with a slide groove 2111 that cooperates with the movable seat 220; the slide groove 2111 can limit the position of the movable seat 220 to ensure its axial movement along the first transmission shaft 230, and at the same time realize the guiding function when the movable seat 220 moves; the second center axis 251 passes through the slide groove 2111 and is connected to the massage head 280.

[0076] In one embodiment of the present invention, the eccentric shaft 261 can extend out of the eccentric shaft connecting portion 271 and then be connected to another massage head 280 to increase the massage area.

[0077] like Figure 3-4 As shown, in one embodiment of the present invention, the cover body 210 includes an upper cover 211 and a lower cover 212; the slide groove 2111 is arranged on the upper cover 211; the lower cover 212 is provided with a guide groove 2121 that cooperates with the multi-functional movable component 200; the guide groove 2121 can limit and guide the bottom of the movable seat 220, and the slide groove 2111 can limit and guide the top of the movable seat 220, ensuring the linear mobility of the movable seat 220, thereby improving the smoothness of the movement of the third bevel gear 232.

[0078] like Figure 7 As shown, in one embodiment of the present invention, a rotating protrusion 2122 is provided on the side of the lower cover 212 away from the massage head 280; a rotating groove 121 that cooperates with the rotating protrusion 2122 is provided on the shell 100; and the multifunctional movable component 200 rotates around the central axis of the rotating protrusion 2122 under the drive of the second driving component 300.

[0079] In one embodiment of the present invention, when the multifunctional movable component 200 rotates relative to the central axis of the rotating protrusion 2122, the side of the multifunctional movable component 200 away from the rotating protrusion 2122 makes line contact with the housing 100. The use of line contact can reduce the contact area between the multifunctional movable component 200 and the housing 100, thereby reducing the friction force when the multifunctional movable component 200 rotates, reducing power consumption, and avoiding the occurrence of motion jamming problems; in one embodiment, the line contact can be formed by the guide groove 2121 protruding outward to form an arc portion that contacts the housing 100; in one embodiment, the guide groove 2121 can be as follows Figure 5 A hollow structure is formed in the middle, and the guide block 2221 is set to be an arc shape. The guide block 2221 protrudes from the hollow position and contacts the shell 100 to form a line contact.

[0080] In one embodiment of the present invention, the movable seat 220 includes an upper movable seat 221 and a lower movable seat 222 that are fixedly connected; a support portion 2222 for supporting the fourth bevel gear 250 is provided in the movable seat 220; a middle portion of the support portion 2222 is provided with a clearance groove 2223 allowing the first transmission shaft 230 to pass through the movable seat 220; the movable seat 220 clamps the third bevel gear 232 and the fourth bevel gear 250 so as to move axially along the first transmission shaft 230 under the drive of the connecting arm 270; a limiting protrusion 2211 is provided on the upper movable seat 221 that cooperates with the slide groove 2111; a first clearance through hole 2212 that cooperates with the second center axis 251 is provided in the middle portion of the limiting protrusion 2211; a guide block 2221 is provided on the side of the lower movable seat 222 close to the cover body 210 that cooperates with the guide groove 2121 axially arranged on the cover body 210 along the first transmission shaft 230.

[0081] In one embodiment of the present invention, a plurality of guide blocks 2221 are arranged at intervals; and the guide blocks 2221 are arc-shaped.

[0082] In one embodiment of the present invention, a first central shaft 242 is provided in the middle of the first worm gear 240; a first connecting gear 260 is rotatably connected to the first central shaft 242. It is understood that the first connecting gear 260 is capable of rotating about the first central shaft 242, and the first central shaft 242 does not transmit torque to the first connecting gear 260; thus, the first worm gear 240 and the first connecting gear 260 rotate independently, with the first central shaft 242 serving only as a positioning function. In one embodiment, the first connecting gear 260 can be connected to the multifunctional movable assembly 200 using an independent central shaft.

[0083] In one embodiment of the present invention, the third drive assembly 400 includes a third drive motor 410 disposed on one side of the first drive motor 130; a third worm gear 421 meshes with a third worm gear 411 of the third drive motor 410; the third worm gear 421 is fixedly mounted at the middle portion of the third transmission shaft 420; third worm portions 422 are formed at both ends of the third transmission shaft 420; and the first connecting gear 260 meshes with the third worm portion 422. In one embodiment, the third drive assembly 400 is preferably disposed on the side of the first drive motor 130 near the first worm gear 240. This extends the length of the connecting arm 270, thereby increasing the axial displacement of the massage head 280 along the first transmission shaft 230 and thereby expanding the massage range. In one embodiment, the third drive assembly 400 may also include two third drive motors 410, each of which controls the rotation of the two first connecting gears 260. Transmission can be achieved using a gear connection or worm gear commonly used in the art.

[0084] In one embodiment of the present invention, a light panel 281 is provided inside the massage head 280, and a cover 282 is provided at the bottom of the massage head 280. The light panel 281 can convert light energy into heat energy on the massage head 280, thereby heating the massage head 280 and ensuring uniform heating.

[0085] In one embodiment of the present invention, the shell 100 includes an upper shell 110 and a lower shell 120; the upper shell 110 is provided with a third clearance hole 112 that cooperates with the first connecting gear 260, and a fourth clearance hole 113 that cooperates with the second center axis 251; the upper shell 110 is provided with a second drive motor limiting cavity 111 that cooperates with the second drive motor 310 in the second drive assembly 300; the lower shell 120 is provided with a sliding belt 122 that protrudes toward the direction of the multifunctional movable assembly 200 and is in line contact with the multifunctional movable assembly 200; the sliding belt 122 can effectively reduce the movement resistance between the multifunctional movable assembly 200 and the shell 100; the lower shell 120 is provided with a third drive motor limiting cavity 123 that cooperates with the third drive motor 410 in the third drive assembly 400.

[0086] The multifunctional movable component 200 of the present invention can not only effectively increase the area covered by the massage, but also, through the cooperation of the second drive component 300 and the third drive component 400, can realize the massage head 280 to stop at any position and then perform massage, thereby realizing free control of precise massage at any point. When the second drive component 300 drives the multifunctional movable component 200 to rotate, it can achieve a pinching and kneading massage effect. By controlling the rotation speed of the first drive motor 130, the second drive motor 310, and the third drive motor 410, it is possible to achieve arbitrary trajectory movement of the massage head 280, so that the massage movement can have a high degree of freedom and can realize built-in multiple massage trajectories to achieve different massage effects; the massage movement is no longer restricted to a single composite motion trajectory, so that it can be applied to multiple massage devices at the same time, and can meet a variety of different massage needs in various scenarios such as the neck, shoulders, back, abdomen, etc. It is understood that the massage head 280 can independently rotate in two directions, ensuring a single-point rotational massage effect. It can also rotate around the rotating protrusion 2122 under the drive of the second drive assembly 300, and reciprocate along the first transmission shaft 230 under the drive of the third drive assembly 400. These three motion modes can be controlled independently or in any combination, ensuring a variety of massage effects. Furthermore, the transmission structure of the present invention can effectively reduce internal space occupation.

[0087] Working principle: when the first drive motor 130 works alone, the first worm 131 drives the first worm gear 240 to rotate, and the first bevel gear 241 will rotate synchronously with the first worm gear 240, and the second bevel gear 231 will rotate under the drive of the first bevel gear 241. Since the second bevel gear 231 is fixedly connected to the first transmission shaft 230, the first transmission shaft 230 will rotate, and the third bevel gear 232 is also fixedly connected to the first transmission shaft 230. The third bevel gear 232 will rotate under the action of the first transmission shaft 230, thereby driving the fourth bevel gear 250 to rotate, and the fourth bevel gear 250 is fixedly connected to the second center shaft 251, and the second center shaft 251 is fixedly connected to the massage head 280, and finally the massage head 280 can be rotated; that is, the first drive motor 130 is mainly used to realize the self-rotation of the massage head 280, so that the massage effect of the massage head 280 at a fixed point can be achieved.

[0088] like Figure 3 、 Figure 6 、 Figure 7As shown, the function of the second driving assembly 300 is to realize the rotation of the multifunctional movable assembly 200 around the central axis of the rotating protrusion 2122, thereby realizing the rotation of the massage head 280 around the central axis of the rotating protrusion 2122; the second driving motor 310 drives the second worm 311 to rotate, and further drives the second worm gear 321 to rotate. The second worm gear 321 is fixedly connected to the second transmission shaft 320, and the second worm gear 321 will drive the second transmission shaft 320 to rotate, further realizing the rotation of the second worm part 322. The rotation of the second worm part 322 will drive the local adjustment tooth 331 to rotate. Since the center of curvature of the local adjustment tooth 331 is located on the central axis of the rotating protrusion 2122, the adjustment seat 330 is connected to the multifunctional movable assembly 200, and finally the multifunctional movable assembly 200 is realized. Rotation around the central axis of the rotating protrusion 2122 is realized.

[0089] The third drive assembly 400 mainly realizes the rotation of the first connecting gear 260. The third drive motor 410 drives the third worm 411 to rotate, further drives the third worm gear 421 to rotate, and the third worm gear 421 is fixedly connected to the third transmission shaft 420. The third worm gear 421 will drive the third transmission shaft 420 to rotate, further realizing the rotation of the third worm part 422. The rotation of the third worm part 422 will drive the rotation of the first connecting gear 260. When the first connecting gear 260 rotates, the change in the position of the eccentric shaft 261 will act on the movable seat 220 through the connecting arm 270. The movable seat 220 is connected to the eccentric shaft 261 on the first connecting gear 260 through the connecting arm 270, so that the movable seat 220 approaches or moves away from the rotation center of the first connecting gear 260, and the movable seat 220 is limited by the sliding groove 2111, so that the movable seat 220 can only move along the length direction of the sliding groove 2111 (that is, the axial direction of the first transmission shaft 230). It should be noted that although the first central shaft 242 can be connected to the first worm gear 240 and the first connecting gear 260 at the same time, no torque is transmitted between the first central shaft 242 and the first worm gear 240 and the first connecting gear 260. The first worm gear 240 and the first connecting gear 260 can both rotate around the first central shaft 242, that is, the rotation of the first worm gear 240 and the first connecting gear 260 is carried out independently; no torque is transmitted between the second central shaft 251 and the connecting arm 270, and the connecting arm 270 can rotate freely around the second central shaft 251.

[0090] like Figure 6As shown, when the first drive motor 130 is working, the massage head 280 is rotated; when the second drive assembly 300 is working, the multifunctional movable assembly 200 is rotated as a whole around the central axis of the rotating protrusion 2122, and the massage head 280 is also driven to rotate around the central axis of the rotating protrusion 2122; when the third drive assembly 400 is working, the movable seat 220 is moved along the axial direction of the first transmission shaft 230, and the massage head 280 is also driven to move along the axial direction of the first transmission shaft 230.

[0091] The first drive motor 130, the second drive assembly 300, and the third drive assembly 400 can work independently without affecting each other, so as to realize the free control of the massage head 280 at any position. It can be understood that the movement of the massage head 280 is mainly the displacement in the XY plane. Figure 6 In the position shown, the second drive assembly 300 can realize the rotation of the massage head 280 in the XY plane when working alone, that is, the massage head 280 can realize the displacement in the X-axis direction and the Y-axis direction, but the displacement in these two directions is limited, and the movement trajectory of the massage head 280 can only be an arc. Figure 6 In the state shown, the massage head 280 mainly achieves displacement in the X-axis direction.

[0092] exist Figure 6 In the state shown, when the third drive component 400 works alone, the massage head 280 can move along the Y-axis direction, and at this time the Y-axis direction is parallel to the direction of the first transmission shaft 230; when the direction of the first transmission shaft 230 is not parallel to the Y-axis, the third drive component 400 can enable the massage head 280 to achieve displacement in the X-axis direction and the Y-axis direction when working; therefore, under the joint action of the second drive component 300 and the third drive component 400, the massage head 280 can be moved to any position within the active range; for ease of understanding, it can be understood that the second drive component 300 mainly controls the displacement of the massage head 280 in the X-axis direction, and the third drive component 400 mainly controls the displacement of the massage head 280 in the Y-axis direction. After the two are superimposed, the control of any position of the massage head 280 can be achieved, and a variety of preset massage trajectories can be formed.

[0093] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's description and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
