Description

A shoulder and neck massager

[0001] This application claims priority to Chinese patent applications No. 2023112618841 and No. 2023226369549 filed on September 27, 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 shoulder and neck massager. Background Art

[0003] The shoulder and neck massager is specially used to massage the user's shoulders and neck. In order to improve the massage effect, the massage head not only performs swinging massage but also tapping massage.

[0004] The shoulder and neck massager is equipped with a main drive shaft and a secondary drive shaft. The massage head holder is mounted on the end of the main drive shaft. The main drive shaft and its attached drive mechanism drive the massage heads to oscillate. Two sets of massage heads, mounted on either side of the main drive shaft, are designed to be hung on either side of the user's neck to massage the shoulders and base of the neck. Both ends of the secondary drive shaft are equipped with a percussion drive mechanism that drives the massage heads in a percussive motion. Rotation of the secondary drive shaft activates the percussion drive mechanism through its attached drive structure, thereby driving the massage heads in a percussive motion.

[0005] In the prior art, to allow users to select whether to activate or deactivate the percussion massage function, a main motor and a secondary motor are typically configured. The main motor drives the main transmission shaft, while the secondary motor drives the secondary transmission shaft, respectively driving the massage heads. The main and secondary motors are each connected to a circuit board via wires, and both motors are controlled by the circuit board. If the user chooses to use both the swing and percussion massage functions simultaneously, the circuit board controls both motors. If the user chooses to use only the swing massage function, the circuit board turns on the main motor and turns off the secondary motor.

[0006] The defects in the prior art are:

[0007] The connection position between the knocking drive mechanism and the massage head bracket is between the two ends of the massage head bracket, which will limit the range of movement of the massage head bracket.

[0008] The integrated circuit board controls the operation of the main and auxiliary motors, resulting in a complex and fault-prone control system. Due to the limited space in the housing and the location of the shoulder and neck massager, the layout of the main and auxiliary motors increases the difficulty and cost of integrated installation. Both motors require wires to connect to the circuit board. Given the limited installation space, the two wire bundles can easily become entangled, requiring extensive wiring space and potentially interfering with surrounding transmission mechanisms.

[0084] The following further describes the specific embodiments of the present application with reference to the accompanying drawings. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0085] As shown in Figures 1-7, 17-18, and 23-26, an embodiment of the present application provides a shoulder and neck massager, comprising a housing 1, a movement 2 connected to the housing 1, a first rotating shaft 3 and a second rotating shaft 4 pivotally connected to the movement 2, two sets of massage head mechanisms 5 installed at both ends of the first rotating shaft 3, and a knocking drive mechanism 6 installed at both ends of the second rotating shaft 4 and correspondingly connected to the two sets of massage head mechanisms 5.

[0086] The end of the first rotating shaft 3 is equipped with a swing driving member 7 for driving the massage head mechanism 5 to swing.

[0087] The movement 2 includes a circuit board 22 and a drive motor 24 connected to the circuit board 22 by signal. The drive motor 24 is connected to the first rotating shaft 3 through a first transmission mechanism 25. The drive motor 24 is connected to the second rotating shaft 4 through a second transmission mechanism 26. A one-way bearing 27 is installed between the second transmission mechanism 26 and the second rotating shaft 4. The end of the second rotating shaft 4 has an eccentric structure 41.

[0088] The knocking drive mechanism 6 includes a hinge seat 61 and a hinge arm 62 hinged to the hinge seat 61 . The hinge seat 61 is connected to the eccentric structure 41 , and the hinge arm 62 is hinged to the pivot end 50 of the massage head mechanism 5 .

[0089] The shoulder and neck massager provided in the present application is driven by a set of drive motors 24, and the massage head mechanism 5 can realize the pinching / kneading / pressing massage function and the tapping massage function.

[0090] The directional words such as up, down, left, and right involved in this application are approximate directions in the corresponding drawings, which are only described for the convenience of description and do not represent the directions in actual use.

[0091] The shoulder and neck massager provided in this application includes a housing 1, a movement 2, a first rotating shaft 3, a second rotating shaft 4, a massage head mechanism 5, a knocking drive mechanism 6 and a swinging drive member 7.

[0092] The shell 1 is a protective shell part of the shoulder and neck massager, which is an open structure. The movement 2 is installed in the shell 1, and the shell 1 covers all or part of the movement 2 and other parts.

[0093] The movement 2 includes a movement housing 21 , a circuit board 22 , a battery 23 , a drive motor 24 , a first transmission mechanism 25 , a second transmission mechanism 26 , a one-way bearing 27 , and the like.

[0094] The circuit board 22 and battery 23 can be optionally mounted outside the movement housing 21. The battery 23 provides power to the drive motor 24 and the circuit board 22. The circuit board 22 is connected to the drive motor 24 via wires and controls the operation of the drive motor 24. The drive motor 24 is a bidirectional motor capable of forward and reverse rotation. It can be a stepper motor or a servo motor.

[0095] The movement housing 21 is composed of a housing base 211 and a housing cover 212, with an installation cavity formed therebetween. The drive motor 24, the first transmission mechanism 25, the second transmission mechanism 26 and the one-way bearing 27 are installed in the installation cavity.

[0096] The first transmission mechanism 25 and the second transmission mechanism 26 can be respectively selected from gear transmission mechanisms, pulley transmission mechanisms, etc.

[0097] The first rotating shaft 3 and the second rotating shaft 4 are arranged in parallel. The first rotating shaft 3 and the second rotating shaft 4 are respectively connected to the movement housing 21 through bearings. The two ends of the first rotating shaft 3 and the second rotating shaft 4 extend out of the outside of the movement housing 21 and are located on the inner side of the outer shell 1.

[0098] Each end of the first rotating shaft 3 is equipped with a swinging drive member 7 and a set of massage head mechanisms 5. The swinging drive member 7 is fixedly mounted on the first rotating shaft 3 and rotates integrally with the first rotating shaft 3. The pivot end 50 of the massage head mechanism 5 is sleeved on the swinging drive member 7 with a clearance fit. The swinging drive member 7 can rotate relative to the massage head mechanism 5 and drive the massage head mechanism 5 to reciprocate through a preset angle along the circumference or axial direction of the first rotating shaft 3. As the massage head mechanism 5 reciprocates through a preset angle along the circumference of the first rotating shaft 3, the massage heads of the massage head mechanism 5 reciprocate between contact and separation with the user, pressing or kneading the contacted areas of the user to provide a kneading or pressing massage. As the massage head mechanism 5 reciprocates through a preset angle along the axial direction of the first rotating shaft 3, the massage heads of the two sets of massage head mechanisms 5 simultaneously swing inward or outward to provide a pinching and kneading massage.

[0099] The swing driving member 7 can be an eccentric driving member to drive the massage head mechanism 5 to swing back and forth along the circumference of the first rotating shaft 3 at a preset angle.

[0100] The swing drive member 7 can be a deflection drive member to drive the massage head mechanism 5 to swing back and forth at a preset angle along the axial direction of the first rotating shaft 3. Of course, when the massage head mechanism 5 swings back and forth along the axial direction of the first rotating shaft 3, it also swings to a certain extent in the circumferential direction to enhance the pinching and kneading massage effect.

[0101] The first transmission mechanism 25 is connected between the motor shaft of the driving motor 24 and the first rotating shaft 3 , and the driving motor 24 drives the first rotating shaft 3 to rotate.

[0102] An eccentric structure 41 and a set of striking drive mechanisms 6 are respectively provided at both ends of the second rotating shaft 4. The eccentric structure 41 can be sleeved on the ends of the second rotating shaft 4 or formed integrally with the second rotating shaft 4. For example, the eccentric structure 41 can be an eccentric wheel, which is sleeved on the ends of the second rotating shaft 4, or the eccentric structure 41 can be an eccentric shaft, which is integrally provided at the ends of the second rotating shaft 4.

[0103] The percussion drive mechanism 6 is used to drive the massage head mechanism 5 to vibrate or swing back and forth along the circumference of the first pivot axis 3. The vibration or swing frequency is fast and the amplitude is small. The massage head of the massage head mechanism 5 can provide percussion massage for the user.

[0104] When the massage head mechanism 5 is driven by the swing drive 7 to swing along the circumferential direction of the first pivot axis 3, the percussion drive 6 drives the massage head mechanism 5 to swing or vibrate several times along the circumferential direction of the first pivot axis 3 each time the massage head mechanism 5 swings or vibrates once. Therefore, the massage head mechanism 5 provides the user with several percussion massages during a kneading or pressing massage cycle. For ease of distinction, the swing or vibration of the massage head mechanism 5 along the circumferential direction of the first pivot axis 3 driven by the swing drive 7 is referred to as a large swing or large vibration, while the swing or vibration of the massage head mechanism 5 along the circumferential direction of the first pivot axis 3 driven by the percussion drive 6 is referred to as a small swing or small vibration.

[0105] Similarly, when the massage head mechanism 5 is driven by the swing drive member 7 to swing along the axial direction of the first pivot axis 3, each time the massage head mechanism 5 swings once, the percussion drive mechanism 6 drives the massage head mechanism 5 to swing or vibrate several times along the circumferential direction of the first pivot axis 3. Therefore, the massage head mechanism 5 provides the user with several percussion massages within a cycle of providing a pinching and kneading massage.

[0106] The percussion drive mechanism 6 includes a hinge base 61 and a hinge arm 62. The hinge base 61 is sleeved onto the eccentric structure 41 and is capable of rotating relative to the hinge base 61. One end of the hinge arm 62 is hingedly connected to the hinge base 61, and the other end is hingedly connected to the pivot end 50 of the massage head mechanism 5. When the second rotating shaft 4 is driven to rotate, the eccentric structure 41 rotates integrally with it. Rotation of the eccentric structure 41 relative to the hinge base 61 causes the hinge base 61 to oscillate back and forth relative to the axis of the second rotating shaft 4. This, in turn, pushes and pulls the pivot end 50 of the massage head mechanism 5 via the hinge arm 62, causing the massage head mechanism 5 to oscillate circumferentially relative to the first rotating shaft 3, thereby achieving the percussion massage function. Because the hinge arm 62 connects to the massage head mechanism 5 at the pivot end 50 of the massage head mechanism 5, rather than at the center of the massage head mechanism's connecting arm or the massage head bracket as in the prior art, the swing restriction of the massage head mechanism 5 is minimized. Compared with the prior art, the swing amplitude of the massage head mechanism 5 is increased in both circumferential and axial swings, thereby increasing the massageable area and improving the performance of the product.

[0107] The second transmission mechanism 26 is connected between the motor shaft of the drive motor 24 and the second rotating shaft 4. The end of the second transmission mechanism 26 connected to the drive motor 24 is called the transmission input end, and the end of the second transmission mechanism 26 connected to the second rotating shaft 4 is called the transmission output end. A one-way bearing 27 is mounted between the second rotating shaft 4 and the transmission output end of the second transmission mechanism 26. The one-way bearing 27 is a bearing that rotates only in one direction and is used to control the rotation of the second rotating shaft 4. If the transmission output end transmits torque in a first direction, the one-way bearing 27 is turned on or activated, and the transmission output end drives the second rotating shaft 4 to rotate integrally with it through the one-way bearing 27. If the transmission output end transmits torque in a second direction opposite to the first direction, the one-way bearing 27 is turned off or not activated, and the torque at the transmission output end is no longer transmitted to the second rotating shaft 4, and the second rotating shaft 4 remains stationary.

[0108] When the drive motor 24 rotates in the forward direction, both the first and second shafts 3 and 4 rotate, and the massage head mechanism 5 can now perform both pinching / kneading / pressing massage functions and percussion massage functions. When the drive motor 24 rotates in the reverse direction, the first shaft 3 rotates while the second shaft 4 remains stationary, and the massage head mechanism 5 only performs the pinching / kneading / pressing massage functions without percussion massage, thereby meeting different user massage needs.

[0109] Therefore, in the shoulder and neck massager provided by the present application, the hinge arm 62 of the knocking drive mechanism 6 is hinged to the pivot end 50 of the massage head mechanism 5, reducing the swing restriction on the massage head mechanism 5.

[0110] The shoulder and neck massager provided in this application is equipped with only one set of drive motors 24. The drive motor 24 drives the first rotating shaft 3 through the first transmission mechanism 25, and then drives the massage head mechanisms 5 at both ends to perform a swinging motion through the swing drive member 7. The drive motor 24 also drives the second rotating shaft 4 through the second transmission mechanism 26, and then drives the knocking drive mechanism 6 to actuate through the eccentric structure 41, thereby driving the massage head mechanism 6 to perform a knocking actuation. A one-way bearing 27 is installed between the second transmission mechanism 26 and the second rotating shaft 4, which can automatically adjust whether the second rotating shaft 4 rotates or not according to the rotation direction of the drive motor 24. When the drive motor 24 rotates in the forward direction, both the first rotating shaft 3 and the second rotating shaft 4 rotate. When the drive motor 24 rotates in the reverse direction, the first rotating shaft 3 rotates, while the second rotating shaft 4 does not rotate.

[0111] In summary, the shoulder and neck massager provided in the present application reduces the swing restriction on the massage head mechanism 5, saves the number of motors, simplifies the control method, reduces the difficulty of motor layout and wiring, and reduces product costs.

[0112] In one embodiment, a one-way bearing 27 is optionally provided between the first transmission mechanism 25 and the first rotating shaft 3. When the drive motor 24 rotates forward, the one-way bearing 27 is connected or activated, the first rotating shaft 3 rotates, and the shoulder and neck massager performs both kneading and tapping massage functions. When the drive motor 24 rotates reversely, the one-way bearing 27 is disconnected or inactive, the first rotating shaft 3 does not rotate, and the shoulder and neck massager only performs the tapping massage function.

[0113] In one embodiment, one-way bearings 27 are optionally provided between the first transmission mechanism 25 and the first rotating shaft 3, and between the second transmission mechanism 26 and the second rotating shaft 4. The two one-way bearings 27 are configured to conduct electricity in opposite directions. When the drive motor 24 rotates forward, only the first rotating shaft 3 rotates, enabling the shoulder and neck massager to achieve a kneading massage function. When the drive motor 24 rotates reversely, only the second rotating shaft 4 rotates, enabling the shoulder and neck massager to achieve a tapping massage function.

[0114] In one embodiment, as shown in Figures 26-29, the drive motor 24 is a single-output shaft motor, and the drive motor 24 includes a motor shaft. The first transmission mechanism 25 and the second transmission mechanism 26 are connected to the motor shaft at intervals.

[0115] In this embodiment, the drive motor 24 uses one motor shaft to assemble with the first transmission mechanism 25 and the second transmission mechanism 26. The first transmission mechanism 25 and the second transmission mechanism 26 are driven by one motor shaft, which has high integration and is conducive to reducing the structural size.

[0116] Specifically, a first matching portion and a second matching portion may be spaced apart along the axial direction on the motor shaft, the first transmission mechanism 25 matches the first matching portion, and the second transmission mechanism 26 matches the second matching portion.

[0117] In one embodiment, as shown in Figures 23-29, the second transmission mechanism 26 includes a driving wheel 261, a driven wheel 262, and a transmission belt connecting the driving wheel 261 and the driven wheel 262.

[0118] The driving wheel 261 is mounted on the motor shaft of the driving motor 24 , the driven wheel 262 is sleeved on the second rotating shaft 4 , and the one-way bearing 27 is mounted between the driven wheel 262 and the second rotating shaft 4 .

[0119] In this embodiment, the second transmission mechanism 26 comprises a driving pulley 261, a driven pulley 262, and a transmission belt (not shown). The driving pulley 261 is integrally mounted on the motor shaft of the drive motor 24, and the driven pulley 262 is the transmission output end of the second transmission mechanism 26. The driven pulley 262 is mounted on the second rotating shaft 4 via a one-way bearing 27.

[0120] The radius of the driving wheel 261 is smaller than the radius of the driven wheel 262, and the transmission belt can be a belt. The second rotating shaft 4 is parallel to the motor shaft of the driving motor 24, and the driving wheel 261 and the driven wheel 262 are in the same plane so that the driving wheel 261 and the driven wheel 262 are connected by the transmission belt to transmit torque.

[0121] In another embodiment, the second transmission mechanism 26 may be a chain transmission or a gear transmission.

[0122] In another embodiment, a one-way bearing 27 may be optionally disposed between the transmission input end of the second transmission mechanism 26 and the motor shaft of the drive motor 24. When the drive motor 24 rotates forward, the one-way bearing 27 is engaged or activated, and the second transmission mechanism 26 rotates and transmits the transmission. When the drive motor 24 rotates reversely, the one-way bearing 27 is disconnected or inactive, and the second transmission mechanism 26 does not rotate and transmit the transmission.

[0123] In one embodiment, as shown in Figures 30-31, the housing base 211 has a motor mounting slot 2111, a first escape slot 2112, and a second escape slot 2113, with the second escape slot 2113 located to one side of the first escape slot 2112. The drive motor 24 is mounted in the motor mounting slot 2111, with at least a portion of the driving pulley 261 located in the first escape slot 2112, and at least a portion of the driven pulley 262 located in the second escape slot 2113.

[0125] In this embodiment, the eccentric structure 41 adopts an eccentric shaft 411 . The eccentric shaft 411 is integrally provided at the end of the second rotating shaft 4 . The hinge seat 61 is mounted on the eccentric shaft 411 via a first bearing 63 .

[0126] Compared with the solution using an eccentric wheel, the solution using the eccentric shaft 411 has a smaller structural size, a relatively smaller swing amplitude of the hinge seat 61 , and a smaller installation space, which is beneficial to reducing the volume of the movement housing 21 .

[0127] In one embodiment, as shown in FIG21 , the two eccentric shafts 411 at both ends of the second rotating shaft 4 are located on opposite sides of the axis of the second rotating shaft 4 , and the swinging of the hinge seats 61 on both sides are not synchronized, so that the tapping actions of the two sets of massage head mechanisms 5 are not synchronized, and the user's massage area will not be tapped at the same time, so as to avoid the problem that some users feel a large force and a poor experience during the tapping massage.

[0128] In one embodiment, as shown in Figures 25-29, the first transmission mechanism 25 includes a worm 251 connected to the motor shaft of the drive motor 24, a worm wheel 252 meshing with the worm 251, and a transmission gear set 253 connected between the worm wheel 252 and the first rotating shaft 3.

[0129] In this embodiment, the first transmission mechanism 25 utilizes a combination of a worm and worm gear mechanism and a transmission gear set 253, providing stable torque transmission. The worm 251 is connected to the motor shaft of the drive motor 24. The worm 251 is coaxially arranged with a driving wheel 261, which is positioned between the drive motor 24 and the worm 251. The worm 251 and driving wheel 261 are integrated onto a single motor shaft of the drive motor 24, providing a high level of integration and facilitating simultaneous torque output. The input gear of the transmission gear set 253 is coaxially arranged and integrally connected to the worm wheel 252, while the output gear of the transmission gear set 253 is sleeved onto the first rotating shaft 3.

[0130] In one embodiment, as shown in Figures 30-31, a worm positioning groove 2114 is provided on the shell base 211, and the worm positioning groove 2114 is arranged opposite to the drive motor 24. One end of the worm 251 can be pivotally assembled in the worm positioning groove 2114, and the worm positioning groove 2114 provides support and limitation for the worm 251.

[0131] In one embodiment, as shown in Figures 25-29, the worm 251 is parallel to the first rotating shaft 3.

[0132] The transmission gear set 253 includes a first gear 2531 integrally provided on the worm gear 252 , a second gear 2532 meshing with the first gear 2531 , a first bevel gear 2533 integrally provided on the second gear 2532 , and a second bevel gear 2534 sleeved on the first rotating shaft 3 and meshing with the first bevel gear 2533 .

[0133] In this embodiment, the transmission gear set 253 includes a first gear 2531, a second gear 2532, a first bevel gear 2533, and a second bevel gear 2534. The first gear 2531 is the input gear of the transmission gear set 253, and the second bevel gear 2534 is the output gear of the transmission gear set 253. The first gear 2531 is coaxially arranged and integrally connected to the worm gear 252. The second gear 2532 is located on one side of the first gear 2531 and meshes with the first gear 2531 for transmission. The first bevel gear 2533 and the second gear 2532 are coaxially arranged and integrally connected. The second bevel gear 2534 is keyed to the first rotating shaft 3. The first bevel gear 2533 and the second bevel gear 2534 mesh to achieve torque steering transmission.

[0134] In one embodiment, as shown in Figures 30-31, the housing base 211 is provided with a worm gear positioning groove 2115, a first positioning post 2116, and a second positioning post 2117. The lower end of the first positioning post 2116 is connected to the worm gear positioning groove 2115, and the second positioning post 2117 is located on one side of the worm gear positioning groove 2115.

[0135] The worm gear 252 is installed in the worm gear positioning groove 2115 . The first gear 2531 and the worm gear 252 are pivotally mounted on the first positioning post 2116 . The second gear 2532 and the first bevel gear 2533 are pivotally mounted on the second positioning post 2117 .

[0136] The first positioning post 2116 and the second positioning post 2117 are connected to the housing upper cover 212 .

[0137] 26-28 , the first rotating shaft 3 and the worm gear 252 are located on opposite sides of the worm 251. The radius of the first gear 2531 is smaller than that of the worm gear 252 and smaller than that of the second gear 2532. Part of the second gear 2532 overlaps with the worm gear 252.

[0138] In this embodiment, the second gear 2532 is located above the worm gear 252, and the second gear 2532 overlaps with the worm gear 252, shortening the distance between the first rotating shaft 3 and the worm 251, which is beneficial to reducing the size of the movement housing 21 along the direction of the first rotating shaft 3 and the second rotating shaft 4, that is, the size in the front-to-back direction.

[0139] In one embodiment, as shown in FIG. 1-7 and FIG. 18 - 19 , the massage head mechanism 5 includes a first massage head component 51 and a second massage head component 52 that are spaced apart from each other. The first massage head component 51 and the second massage head component 52 are connected to the swing drive 7 .

[0140] The hinge arm 62 is hingedly connected to the pivot end of the first massage head component 51 and / or the second massage head component 52 .

[0141] In this embodiment, the massage head mechanism 5 includes a first massage head component 51 and a second massage head component 52. The first massage head component 51 and the second massage head component 52 are arranged at an interval, with the first massage head component 51 being located outside the second massage head component 52. The first massage head component 51 and the second massage head component 52 can massage the user separately.

[0142] The first massage head component 51 and the second massage head component 52 are each connected to an oscillating drive element 7. Optionally, one oscillating drive element 7 may be mounted at the end of the first rotating shaft 3, with the first massage head component 51 and the second massage head component 52 being simultaneously connected to the same oscillating drive element 7. Alternatively, two oscillating drive elements 7 may be mounted at the end of the first rotating shaft 3, with the first massage head component 51 and the second massage head component 52 being each connected to one oscillating drive element 7. The two oscillating drive elements 7 may be two eccentric drive elements, two skew drive elements, or a combination of an eccentric drive element and a skew drive element.

[0143] The hinge arm 62 of the knock drive mechanism 6 is hinged to the pivot end of the first massage head component 51 and / or the second massage head component 52 .

[0144] When the hinge arm 62 is hinged to the pivot end of the first massage head component 51, the first massage head component 51 has a pinching / kneading / pressing massage function and a tapping massage function. When the hinge arm 62 is hinged to the pivot end of the second massage head component 52, the second massage head component 52 has a pinching / kneading / pressing massage function and a tapping massage function. When the hinge arm 62 is hinged to the pivot ends of both the first massage head component 51 and the second massage head component 52, the first massage head component 51 and the second massage head component 52 respectively have a pinching / kneading / pressing massage function and a tapping massage function.

[0145] The pivot ends of the first massage head component 51 and the second massage head component 52 are connected to the swing drive member 7 .

[0146] In one embodiment, as shown in Figures 15-16 and 18-19, the first massage head component 51 includes a first assembly ring 511, a first connecting arm 512 and a first massage head 513 connected in sequence, and the second massage head component 52 includes a second assembly ring 521, a second connecting arm 522 and a second massage head 523 connected in sequence.

[0147] The first mounting ring 511 and / or the second mounting ring 521 are connected to the pivot drive 7 .

[0148] The hinge arm 62 is hinged to the first mounting ring 511 and / or the second mounting ring 521 .

[0149] In this embodiment, the first massage head component 51 includes a first assembly ring 511, a first connecting arm 512, and a first massage head 513, which are sequentially connected. The first assembly ring 511 serves as the pivot point of the first massage head component 51. The swing drive member 7 can be mounted within the first assembly ring 511. The swing drive member 7 can rotate relative to the first assembly ring 511, thereby driving the first assembly ring 511 to swing a predetermined angle along the axial direction of the first rotating shaft 3 or to reciprocate along the axial direction, thereby driving the first massage head component 51 to swing integrally. A bearing can be installed between the first assembly ring 511 and the swing drive member 7 to reduce friction.

[0150] The second massage head component 52 includes a second mounting ring 521, a second connecting arm 522, and a second massage head 523, which are sequentially connected. The second mounting ring 521 serves as the pivot point of the second massage head component 52. The swing driver 7 is mounted within the second mounting ring 521. The swing driver 7 can rotate relative to the second mounting ring 521, thereby driving the second mounting ring 521 to swing back and forth along the axis of the first rotating shaft 3 or along the axis through a predetermined angle, thereby driving the second massage head component 52 to swing integrally. A bearing may be installed between the second mounting ring 521 and the swing driver 7 to reduce friction.

[0151] The first connecting arm 512 and the second connecting arm 522 can be configured as straight arms or curved arms to facilitate better coordination between the massage head and the human body. The second connecting arm 522 has a curved portion 5221, so that the end of the second connecting arm 522 extends upwardly at an angle, and the second massage head 523 is connected to the end of the second connecting arm 522.

[0152] In one embodiment, the first connecting arm 512 and the second connecting arm 522 are arranged crosswise to avoid interference.

[0153] In one embodiment, as shown in FIG19 , the knock drive mechanism 6 and the second connecting arm 522 are located on the same side of the second assembly ring 521 , and the knock drive mechanism 6 is located below the second connecting arm 522 . The hinge arm 62 is hinged to the second assembly ring 521 .

[0154] In this embodiment, the knocking drive mechanism 6 is only used to drive the second massage head component 52 to perform knocking massage. The second massage head component 52 can perform pinching / kneading / pressing massage and knocking massage. The first massage head component 51 can only perform pinching / kneading / pressing massage.

[0155] With this arrangement, targeted massage can be performed specifically on different parts of the user's body.

[0156] In one embodiment, as shown in FIG. 19 , a hinge seat 524 is provided at the lower half of the second assembly ring 521 , and a central angle between the hinge seat 524 and the second massage head 523 is between 95° and 125°.

[0157] One end of the hinge arm 62 is hinged to the hinge seat 524 .

[0158] In this embodiment, a hinge seat 524 is provided at the bottom of the second assembly ring 521 for articulation with the hinge arm 62. The central angle α between the hinge seat 524 and the second massage head 523 is an obtuse angle, ranging from 95° to 125°. This prevents an excessively large central angle from causing the transmission chain between the percussion drive mechanism and the hinge seat 524 to be too long, thereby affecting the stability of the transmission connection.

[0159] The central angle α is the angle between the extension direction of the second massage head 523 relative to the center of the second mounting ring 521 and the extension direction of the hinged seat 524 relative to the center of the second mounting ring 521. This angle is obtuse and lies between 95° and 125°. This ensures that the hinged seat 524 does not extend toward the second massage head 523 or the second connecting arm 522. This prevents the hinged seat 524 from being too close to the percussion drive mechanism due to a too small central angle, which would result in limited space for the transmission connection and make installation difficult. Setting the central angle α between 95° and 125° also prevents the transmission chain between the percussion drive mechanism and the hinged seat 524 from being too long due to a too large central angle.

[0160] In one embodiment, as shown in FIG. 4-9 and FIG. 16 , the end of the hinge arm 62 connected to the hinge seat 524 has a hinge ball head 621 .

[0161] The hinge seat 524 includes a fixing plate 5241 integrally connected to the second assembly ring 521 and a cover plate 5242 detachably connected to the fixing plate 5241 . A ball head receiving groove 5243 is formed between the cover plate 5242 and the fixing plate 5241 .

[0162] The articulated ball head 621 is assembled in the ball head receiving groove 5243 .

[0163] In this embodiment, the hinge seat 524 is composed of a fixed plate 5241 and a cover plate 5242. The fixed plate 5241 is integrally arranged in the lower half of the second assembly ring 521. The cover plate 5242 is connected to the fixed plate 5241 by pins. The surfaces of the fixed plate 5241 and the cover plate 5242 are respectively provided with hemispherical grooves. After the cover plate 5242 is assembled to the fixed plate 5241, the two hemispherical grooves are connected to form a ball head accommodating groove 5243.

[0164] One end of the hinge arm 62 is integrally provided with a hinge ball 621. During assembly, the hinge ball 621 is first placed in the hemispherical groove of the fixing plate 5241, and then the cover plate 5242 is installed to fit the hinge ball 621 into the ball receiving groove 5243. The ball hinge method provides a stable structure and flexible movement.

[0165] In one embodiment, as shown in FIG. 10 , the swing driving member 7 includes an eccentric driving wheel 71 sleeved on the end of the first rotating shaft 3 .

[0166] The first assembly ring 511 and / or the second assembly ring 521 are connected to the eccentric drive wheel 71 , and the eccentric drive wheel 71 can drive the first massage head component 51 and / or the second massage head component 52 to swing along the circumferential direction.

[0167] In this embodiment, the swing drive member 7 employs an eccentric drive wheel 71 having an eccentric hole 711 connected to the first rotating shaft 3. The eccentric hole 711 is a non-circular or elliptical hole. The end of the first rotating shaft 3 is provided with a plug-in end 31 with a non-circular or elliptical cross-section. This plug-in end 31 plugs into the eccentric hole 711 to facilitate torque transmission. A decorative cover 33 is mounted on the plug-in end 31 to conceal the first mounting ring 511 and the eccentric drive wheel 71.

[0168] The first assembly ring 511 and / or the second assembly ring 521 are sleeved on the eccentric drive wheel 71. When the eccentric drive wheel 71 is driven to rotate by the pivot shaft, the eccentric drive wheel 71 will cause the first assembly ring 511 and / or the second assembly ring 521 to swing back and forth in the circumferential direction, thereby driving the entire first massage head component 51 and / or the second massage head component 52 to swing roughly up and down to achieve pressing / rubbing massage.

[0169] In one embodiment, as shown in FIG. 8 and FIG. 11 - 14 , the swing driving member 7 includes a deflecting driving body 72 sleeved on the end of the first rotating shaft 3 .

[0170] The deflection driving body 72 includes a first column portion 721 and a second column portion 722 connected to each other.

[0171] The deflection driving body 72 further includes a driving body through hole 723 for the first rotating shaft 3 to pass through, wherein non-zero angles are formed between the axes of the first column portion 721 and the second column portion 722 and the axis of the driving body through hole 723 .

[0172] The first assembly ring 511 is assembled on the first column portion 721 , and the second assembly ring 521 is assembled on the second column portion 722 .

[0173] In this embodiment, the swing drive member 7 utilizes an angular drive body 72, which is generally cylindrical and has a non-circular or elliptical drive body through-hole 723. The end of the first rotating shaft 3 is provided with a plug-in end 31 having a non-circular or elliptical cross-section. The plug-in end 31 is inserted into the drive body through-hole 723 to facilitate torque transmission.

[0174] The axis OA of the driving body through hole 723 is not parallel to the axis OB of the skew driving body 72 , and there is a non-zero acute angle between the axis OA and the axis OB. Therefore, the axis OA is arranged obliquely to the circumferential surface of the skew driving body 72 .

[0175] The deflection driver 72 includes an integrally connected first column portion 721 and a second column portion 722. The first column portion 721 is located outside the second column portion 722, and the driver through hole 723 extends through the first column portion 721 and the second column portion 722. Therefore, the axis OA is arranged at an angle to the circumferential surfaces of the first column portion 721 and the second column portion 722.

[0176] The first assembly ring 511 is pivotally mounted on the first cylindrical portion 721, and the second assembly ring 521 is pivotally mounted on the second cylindrical portion 722. Therefore, the first assembly ring 511 and the second assembly ring 521 are each arranged obliquely relative to the first rotation axis 3. When the oblique driving body 72 is driven to rotate, the first cylindrical portion 721 and the second cylindrical portion 722 respectively drive the first assembly ring 511 and the second assembly ring 521 to swing axially, thereby causing the first massage head component 51 and the second massage head component 52 to swing axially, respectively, to achieve a pinching and kneading massage.

[0177] In one embodiment, as shown in Figures 8 and 11-13, the radius of the first column portion 721 is greater than the radius of the second column portion 722, the first assembly ring 511 can only be assembled to the first column portion 721, and the second assembly ring 521 can only be assembled to the second column portion 722, thereby preventing misassembly.

[0178] Specifically, as shown in Figures 8-9 and 11-13, the second mounting ring 521 can be assembled onto the second column portion 722 via a bearing 525. A mounting groove 726 is defined at one end of the second column portion 722, distal from the first column portion 721. A retaining ring 526 is mounted within the mounting groove 726 to limit the position of the bearing 525. The distal end of the second column portion 722 is retained by a retaining ring 32 mounted on the plug end 31, while the distal end of the first column portion 721 is retained by a decorative cap 33 mounted on the plug end 31.

[0179] In one embodiment, as shown in FIG. 11-13 , the second column portion 722 is coaxially arranged with the first column portion 721 , so that the first massage head component 51 and the second massage head component 52 swing synchronously.

[0180] In one embodiment, as shown in Figures 11-14, a spacing boss 724 is provided between the first column portion 721 and the second column portion 722 to separate the first assembly ring 511 from the second assembly ring 521. The stepped surface where the spacing boss 724 meets the second column portion 722 contacts the bearing 525, acting as a limiter.

[0181] One end where the first column portion 721 and the second column portion 722 are connected further has a limiting protruding ring 725 , and the first assembly ring 511 is loosely assembled between the limiting protruding ring 725 and the decorative cover 33 .

[0182] In one embodiment, as shown in FIG. 15-16 , the first massage head 513 and / or the second massage head 523 is a rolling massage head.

[0183] In this embodiment, the first massage head 513 and the second massage head 523 can be configured as a rolling massage head or a fixed massage head as needed to meet different massage needs.

[0184] In one embodiment, the second massage head 523 is fixedly mounted on the end of the second connecting arm 522. A pivot shaft 514 is provided at the end of the first connecting arm 512, and the first massage head 513 is pivotally mounted on the pivot shaft 514 to achieve rolling massage.

[0185] In one embodiment, as shown in FIG. 15-16 , the first massage head component 51 includes a plurality of first massage heads 513 , and / or the second massage head component 52 includes a plurality of second massage heads 523 .

[0186] In this embodiment, the first massage head 513 and the second massage head 523 can be provided in multiple forms as needed to meet different massage needs.

[0187] In this application, "multiple" refers to two or more. As needed, the above technical solutions can be combined to achieve the best technical effect. The above are merely the principles and preferred embodiments of this application. It should be noted that those skilled in the art can make several other variations based on the principles of this application, which should also be considered within the scope of protection of this application.
