[0003] Existing massagers offer limited massage modes, failing to meet users' needs for diverse massage options and negatively impacting the user experience. Utility Model Content

[0004] The main purpose of this invention is to propose a massager that aims to solve the problem of the limited massage modes of existing massagers.

[0005] To achieve the above objectives, the massager proposed in this utility model includes:

[0006] The first massage arm is equipped with a first massage head;

[0007] The first rotating shaft drives the first massage arm to a first position through the first eccentric structure, and the first massage arm can rotate relative to the first eccentric structure.

[0008] A connecting rod and a first transmission structure, wherein the connecting rod has a first end and a second end disposed opposite to each other, the first end being rotatably connected to a second position of the first massage arm, and the second end being rotatably connected to the first transmission structure, the first transmission structure having a transmission state and a positioning state; and

[0009] A switching structure is used to switch the first transmission structure between a transmission state and a positioning state.

[0010] In the transmission state, the first transmission structure can drive the second end to reciprocate along the first direction, so that the connecting rod drives the second position, and the second position drives the first massage arm to swing back and forth around the first eccentric structure. At the same time, the first rotating shaft drives the first massage arm through the first eccentric structure.

[0011] In the positioning state, the first transmission structure enables the second end to be positioned, the first rotating shaft drives the first massage arm through the first eccentric structure, the first massage arm slides back and forth, and at the same time the second position drives the first end so that the connecting rod swings back and forth around the second end.

[0012] In one embodiment, the first transmission structure includes an eccentric shaft and a transmission assembly, the transmission assembly being tractively connected to the eccentric shaft and a second end, the eccentric shaft being arranged parallel to the first rotating shaft;

[0013] In the transmission state, the eccentric shaft can rotate in one direction and drive the transmission assembly so that the transmission assembly drives the second end to reciprocate along the first direction;

[0014] In the aforementioned positioning state, the eccentric shaft is positioned to position the second end.

[0015] In one embodiment, the transmission assembly includes a first guide portion, a sliding portion slidably disposed on the first guide portion, and a first transmission rod, wherein the first guide portion extends along a first direction, and the first transmission rod rotatably connects the sliding portion and the eccentric shaft;

[0016] The second end of the connecting rod is rotatably connected to the connection between the first transmission rod and the sliding part, or rotatably connected to the sliding part.

[0017] In one embodiment, the first guide portion is configured as a guide rail, and the sliding portion is configured as a slider.

[0018] In one embodiment, the massager further includes a position detection component for monitoring the position of the second end of the connecting rod. The position detection component is connected to a first transmission structure for positioning the second end of the connecting rod at a preset position.

[0019] In one embodiment, the position detection component includes a Hall plate and two magnets, one of which is disposed on the Hall plate, and the other magnet is coaxially disposed with the eccentric shaft and can rotate with the eccentric shaft. The Hall plate is used to monitor the position of the magnet that rotates with the eccentric shaft.

[0020] In one embodiment, the massager further includes a second rotating shaft and a second transmission structure. The second rotating shaft is arranged parallel to the first rotating shaft. The eccentric shaft is eccentrically disposed on the second rotating shaft through the second transmission structure. The second rotating shaft can rotate in two directions. When the second rotating shaft switches between the two rotation directions, the switching structure can switch the power transmission between the second rotating shaft and the second transmission structure, so that the first transmission structure switches between a transmission state and a positioning state.

[0021] In one embodiment, the second transmission structure includes a first transmission wheel, and the eccentric shaft is eccentrically disposed relative to the second rotation shaft via the first transmission wheel;

[0022] The switching structure includes a one-way bearing, and the first transmission wheel is mounted on the second rotating shaft via the one-way bearing.

[0023] In one embodiment, the massager further includes a drive shaft, a third transmission structure, and a fourth transmission structure. The drive shaft is connected to the first rotating shaft via the third transmission structure, and the drive shaft is connected to the second rotating shaft via the fourth transmission structure.

[0024] The third transmission structure includes a first transmission part and a second transmission wheel that are connected by transmission. The drive shaft rotates coaxially with the first transmission part, and the second transmission wheel is drivenly connected to the first rotation shaft.

[0025] The fourth transmission structure includes a second transmission part and a third transmission wheel that are connected by transmission. The second transmission part rotates coaxially with the drive shaft, and the third transmission wheel is drivenly connected to the second rotation shaft.

[0026] Both the first transmission part and the second transmission part are configured as worm gears.

[0027] In one embodiment, the massager further includes a housing, a second massage arm, a second massage head disposed on the second massage arm, and a limiting part. The housing is provided with a second guide part corresponding to the limiting part. The first rotating shaft is drivenly connected to the second massage arm. When the first rotating shaft drives the second massage arm, the limiting part can slide back and forth in the second guide part to make the second massage arm swing back and forth.

[0028] And / or, the first eccentric structure includes an eccentric wheel, the eccentric wheel being drivenly connected to the first massage arm, the first massage arm being rotatable relative to the eccentric wheel.

[0029] The technical solution of this utility model employs a switching structure to switch the first transmission structure between a transmission state and a positioning state. When the first transmission structure is in the transmission state, it can drive the second end to reciprocate along a first direction, causing the connecting rod to drive the second position, which in turn reciprocates. The second position causes the first massage arm to oscillate back and forth around the first eccentric structure. Simultaneously, the second end of the connecting rod oscillates back and forth around the first end. Since the first massage arm can rotate relative to the first eccentric structure, when the connecting rod drives the first massage arm, it can oscillate back and forth relative to the first eccentric structure under the action of the connecting rod. This allows the first massage head to also oscillate back and forth relative to the first eccentric structure, thereby enabling the first massage arm to achieve a massage method, namely, a combined kneading and tapping massage. When the first transmission structure is in the positioning state, the first transmission structure can position the second end. At this time, the first rotating shaft drives the first massage arm, and the second position drives the first end, so that the connecting rod swings back and forth around the second end. At this time, the first massage arm slides back and forth under the drive of the first eccentric structure and the restriction of the connecting rod. The first massage head also slides back and forth with the first massage arm, thereby realizing another massage mode of the first massage arm, namely kneading massage. Attached Figure Description

[0056] A massager is a device used to provide self-massage or assisted massage, which can relieve muscle tension, reduce pain, improve blood circulation, and help relax the mind and body. A massager consists of a massage unit and a drive mechanism that operates the massage unit.

[0057] Existing massagers offer limited massage modes, failing to meet users' needs for diverse massage options and negatively impacting the user experience.

[0058] This invention proposes a massager that solves the problem of existing massagers having a limited range of massage modes.

[0059] Please see Figure 1 or Figure 3 In one embodiment of this utility model, the massager includes:

[0060] A first massage arm 100 and a first rotating shaft 200 are present. The first massage arm 100 is provided with a first massage head 110, which can be a spherical head, a cylindrical head, a flat head, etc., and the first massage heads 110 can be detachably connected or fixedly connected. The first rotating shaft 200 drives the first massage arm 100 to a first position through a first eccentric structure 300, and the first massage arm 100 can rotate relative to the first eccentric structure 300. The first rotating shaft 200 can be the output shaft of a drive motor.

[0061] The connecting rod 400 and the first transmission structure 500 are provided. The connecting rod 400 has a first end 410 and a second end 420 that are disposed opposite to each other. The first end 410 is rotatably connected to a second position of the first massage arm 100, and the second end 420 is rotatably connected to the first transmission structure 500. The first transmission structure 500 has a transmission state and a positioning state. In this embodiment, the first transmission structure 500 can be a linear reciprocating transmission module, including a cylinder reciprocating transmission module, a hydraulic reciprocating transmission module, and an electric telescopic reciprocating transmission module. Specifically, when the first transmission structure 500 is in the transmission state, the first transmission structure 500 can drive the second end 420 to reciprocate along the first direction, so that the connecting rod 400 drives the second position and drives the second position to reciprocate. The second position drives the first massage arm 100 to swing back and forth around the first eccentric structure 300. At the same time, the second end 420 of the connecting rod 400 swings back and forth around the first end 410. Since the first massage arm 100 can rotate relative to the first eccentric structure 300, when the connecting rod 400 drives the first massage arm 100, the first massage arm 100 can swing back and forth relative to the first eccentric structure 300 under the driving action of the connecting rod 400. This allows the first massage head 110 to also swing back and forth relative to the first eccentric structure 300, thereby enabling the first massage arm 100 to achieve a massage method, namely, a kneading and tapping composite massage.

[0062] When the first transmission structure 500 is in the positioning state, it can position the second end 420. At this time, the first rotating shaft 200 drives the first massage arm 100 through the first eccentric structure 300, and simultaneously drives the first end 410 in the second position, so that the connecting rod 400 swings back and forth around the second end 420. At this time, the first massage arm 100 slides back and forth under the drive of the first eccentric structure 300 and the restriction of the connecting rod 400. The first massage head 110 also slides back and forth following the first massage arm 100, thereby realizing another massage mode of the first massage arm 100, namely, kneading massage. Further, the massager of this embodiment also includes a switching structure 600, which is used to switch the first transmission structure 500 between the transmission state and the positioning state. The switching structure 600 can be a control button and a control program for controlling the start and stop of the first transmission structure 500. Specifically, the control program can be a control circuit.

[0063] In one embodiment, the first transmission structure 500 includes an eccentric shaft 510 and a transmission assembly 520. The transmission assembly 520 drivesly connects the eccentric shaft 510 and the second end 420. The eccentric shaft 510 is arranged parallel to the first rotating shaft 200. Further, in this embodiment, the eccentric shaft 510 can be the output end of an eccentric motor. In this case, the switching structure 600 can be a control button and a control program for controlling the start and stop of the eccentric motor.

[0064] In the transmission state, the eccentric shaft 510 can rotate in one direction. When the eccentric motor drives the eccentric shaft 510 to rotate, it can rotate in either of the two directions. During the rotation, the eccentric shaft 510 drives the transmission assembly 520, so that the transmission assembly 520 drives the second end 420, causing the second end 420 to reciprocate along the first direction, thereby realizing a massage mode of the first massage arm 100.

[0065] In the aforementioned positioning state, the eccentric shaft 510 is positioned so that the second end 420 is positioned. Specifically, when the eccentric shaft 510 stops moving, the transmission component 520 also stops moving, thereby positioning the second end 420. Furthermore, when the transmission structure in this embodiment adopts a flexible transmission structure, it should be such that when the eccentric shaft 510 stops moving, the second end 420 of the connecting rod 400 is also in a stationary state, thereby realizing another massage mode of the first massage arm 100.

[0066] In one embodiment, reference Figure 2 or Figure 4 The transmission assembly 520 includes a first guide portion 521, a sliding portion 522 slidably disposed on the first guide portion 521, and a first transmission rod 523. The first guide portion 521 extends along a first direction, and the first transmission rod 523 rotatably connects the sliding portion 522 and the eccentric shaft 510. Further, in this embodiment, when the eccentric shaft 510 drives the first transmission rod 523 to rotate, the first transmission rod 523 drives the sliding portion 522 to reciprocate along the first guide portion 521. Further, the second end 420 of the connecting rod 400 is rotatably connected to the connection between the first transmission rod 523 and the sliding portion 522, or rotatably connected to the sliding portion 522. When the sliding portion 522 reciprocates along the first guide portion 521, it drives the second end 420 to reciprocate, thereby realizing a massage mode of the first massage arm 100.

[0067] In one embodiment, reference Figure 2 The first guide portion 521 is configured as a guide rail, and the sliding portion 522 is configured as a slider. The guide rail can be a convex rail, a groove, or other structure. The slider can be covered by the guide rail or can be configured to cover the guide rail.

[0068] Furthermore, in this embodiment, reference is made to... Figure 4 The guide rail can also be configured as a guide sleeve, and the slider can also be configured as a second transmission rod. Furthermore, in this embodiment, the second transmission rod passes through the guide sleeve.

[0069] In one embodiment, the massager further includes a position detection component 700, which is used to monitor the position of the second end 420 of the connecting rod 400. The position detection component 700 is connected to a first transmission structure 500, which is used to position the second end of the connecting rod at a preset position. Further, in this embodiment, the position detection component 700 can use a linear displacement monitoring component to detect the position of the second end 420 of the connecting rod 400, and cooperate with the eccentric shaft 510 in the first transmission structure 500 to position the second end 420 of the connecting rod 400. Specifically, when the eccentric shaft 510 is positioned, the second end 420 of the connecting rod 400 is also positioned. At this time, when the first rotating shaft 200 drives the first massage arm 100, the massage position of the first massage arm 100 can change according to the different positions of the second end 420 of the connecting rod 400.

[0070] In one embodiment, the position detection component 700 may also adopt the following structure, as shown in the reference. Figure 6 Furthermore, the position of the second end 420 of the connecting rod 400 is detected by detecting the position of the eccentric shaft 510. The position detection component 700 includes a Hall plate 710 and two magnets 720, one of which is disposed on the Hall plate 710, and the other magnet 720 is coaxially disposed with the eccentric shaft 510 and can rotate with the eccentric shaft 510. The Hall plate 710 is used to monitor the position of the magnet 720 that rotates with the eccentric shaft 510. Further, when the eccentric shaft 510 rotates, the magnet 720 rotates with the eccentric shaft 510. When the magnet 720 rotates, the Hall plate 710 can sense the position of the magnet 720 that rotates with the eccentric shaft 510 by the change in the magnetic field generated by the two magnets 720, thereby realizing the position detection of the eccentric shaft 510.

[0071] Furthermore, in this embodiment, the eccentric shaft 510 can still serve as the output shaft of the eccentric motor. At this time, the position detection component 700 is electrically connected to the eccentric motor. The position detection component 700 detects the position of the eccentric shaft 510. When a suitable position is detected, the eccentric motor stops rotating. At this time, the eccentric shaft 510 is positioned at this location. When the eccentric shaft 510 is positioned at this location, the transmission component 520 can position the second end 420 of the connecting rod 400 at the corresponding position. At this time, when the first rotating shaft 200 drives the first massage arm 100, the massage position of the first massage arm 100 can change according to the different positions of the eccentric shaft 510.

[0072] However, this design is not limited to this. In other embodiments, the position detection component 700 can also be an angle sensor. The angle sensor can obtain the position of the eccentric shaft 510 rotating around the rotation axis and feed it back to the eccentric motor. This allows the user to obtain the position of the eccentric shaft 510 based on the rotation angle of the eccentric shaft 510, thereby positioning the eccentric shaft 510 in a suitable position to achieve the positioning of the first massage arm 100 in a suitable position.

[0073] In one embodiment, reference Figure 1 or Figure 3 The massager further includes a second rotating shaft 800 and a second transmission structure 900. The second rotating shaft 800 is arranged parallel to the first rotating shaft 200. The eccentric shaft 510 is eccentrically arranged relative to the second rotating shaft 800 via the second transmission structure 900. The second rotating shaft 800 can rotate in two directions. When the second rotating shaft 800 switches between the two rotation directions, the switching structure 600 can switch the power transmission between the second rotating shaft 800 and the second transmission structure 900, so that the first transmission structure 500 switches between a transmission state and a positioning state. Further, in this embodiment, the second rotating shaft 800 can serve as the output shaft of a drive motor. In this case, when the second rotating shaft 800 rotates in one direction, it can drive the second transmission structure 900 under the action of the switching structure 600, thereby driving the eccentric shaft 510 through the second transmission structure 900. When the second rotating shaft 800 rotates in another direction, it cannot drive the second transmission structure 900 under the action of the switching structure 600. At this time, the second transmission structure 900 also cannot drive the eccentric shaft 510 to position the eccentric shaft 510, thereby realizing the switching of the first transmission structure 500 between the transmission state and the positioning state. Further, in this embodiment, the switching structure 600 may include a control button and a control program, wherein the control button can control the first rotating shaft 200 and the second rotating shaft 800 to rotate and stop simultaneously.

[0074] In one embodiment, reference Figure 1 or Figure 3The second transmission structure 900 includes a first transmission wheel 910, and the eccentric shaft 510 is eccentrically mounted on the second rotating shaft 800 via the first transmission wheel 910. The switching structure 600 includes a one-way bearing, and the first transmission wheel 910 is mounted on the second rotating shaft 800 via the one-way bearing. Further, when the second rotating shaft 800 rotates in one direction, the one-way bearing is under load, driving the first transmission wheel 910. The first transmission wheel 910 can then drive the eccentric shaft 510, causing it to rotate around its rotation axis, i.e., around the second rotating shaft 800. At this time, the first transmission structure 500 is in a transmission state. When the second rotating shaft 800 rotates in another direction, the one-way bearing is unloaded, and the second rotating shaft 800 does not drive the first transmission wheel 910. Therefore, the first transmission wheel 910 does not drive the eccentric shaft 510, thus positioning the eccentric shaft 510 at that location, achieving positioning transmission for the first transmission structure 500. Furthermore, in this embodiment, when the position sensing component is located in the second transmission structure 900, a magnet is mounted on the first transmission wheel 910 and coaxially arranged with the eccentric shaft 510. The second rotating shaft 800 passes through the Hall plate 710, and there is a clearance fit between the second rotating shaft 800 and the Hall plate 710. That is, when the second rotating shaft 800 rotates, the Hall plate 710 does not rotate. However, the one-way bearing in this design can also be an overrunning clutch with other structures in other embodiments, such as a ratchet overrunning clutch.

[0075] In one embodiment, reference Figure 1 or Figure 3 The massager further includes a drive shaft 10, a third transmission structure 20, and a fourth transmission structure 30. The drive shaft 10 is connected to the first rotating shaft 200 via the third transmission structure 20, and the drive shaft 10 is connected to the second rotating shaft 800 via the fourth transmission structure 30. The drive shaft 10 is capable of bidirectional rotation, and the first rotating shaft 200 and the second rotating shaft 800 can also rotate bidirectionally via the third transmission structure 20 and the fourth transmission structure 30. In this embodiment, the drive shaft 10 can be the output shaft of a motor.

[0076] In one embodiment, reference Figure 5The third transmission structure 20 includes a first transmission part 21 and a second transmission wheel 22 connected by transmission. The drive shaft 10 is driven to the first transmission part 21, and the second transmission wheel 22 rotates coaxially with the first rotating shaft 200. The fourth transmission structure 30 includes a second transmission part 31 and a third transmission wheel 32 connected by transmission. The second transmission part 31 rotates coaxially with the drive shaft 10, and the third transmission wheel 32 is driven to the second rotating shaft 800. The first transmission part 21 and the second transmission part 31 can be configured as transmission gears. When the transmission gears are helical gears, the second transmission wheel 22 and the third transmission wheel 32 are correspondingly helical gears. At this time, the axis of the drive shaft 10 is set perpendicular to the axis of the first rotating shaft 200. When the transmission gear is configured as a spur gear, the axis of the drive shaft 10 is set parallel to the axis of the first rotating shaft 200. At this time, the transmission between the first transmission part 21 and the second transmission wheel 22, and between the second transmission part 31 and the third transmission wheel 32, can be completed by a synchronous belt, chain, or transmission gear. At the same time, the output speed and torque of the third transmission structure 20 and the fourth transmission structure 30 can be adjusted according to the transmission ratio during the transmission process.

[0077] Furthermore, both the first transmission part 21 and the second transmission part 31 are configured as worm gears. The worm gear can be formed on the drive shaft 10 or can be sleeved on the drive shaft 10. The worm gear is driven to connect with the second transmission wheel 22 and the third transmission wheel 32. At this time, the second transmission wheel 22 and the third transmission wheel 32 can be configured as worm gears or other gear structures that can cooperate with the worm gear. When the worm gear transmission is performed, the second transmission structure 900 and the third transmission structure 20 have a self-locking function. That is to say, the worm gear can drive the worm wheel to rotate, but the worm wheel cannot drive the worm gear to rotate.

[0078] In one embodiment, reference Figure 2 or Figure 4 The first eccentric structure 300 includes an eccentric wheel 310, which is connected to the first massage arm 100. The first massage arm 100 can rotate relative to the eccentric wheel 310. The first massage arm 100 has a mounting hole 120, and the first eccentric wheel 310 is disposed in the mounting hole 120. When the first rotating shaft 200 drives the first eccentric wheel 310 to rotate eccentrically, the first eccentric wheel 310 can drive the first massage arm 100 to move through the mounting hole 120, and at the same time, the first massage arm 100 can rotate relative to the first eccentric wheel 310 through the mounting hole 120.

[0079] In one embodiment, the massager further includes a housing (not shown), a second massage arm 40, a second massage head 41 disposed on the second massage arm 40, and a limiting part 50. The housing has a second guide part 42 corresponding to the limiting part 50. The first rotating shaft 200 is drivenly connected to the second massage arm 40. When the first rotating shaft 200 drives the second massage arm 40, the limiting part 50 can slide back and forth in the second guide part 42, so that the second massage arm 40 swings back and forth. Further, the second guide part 42 is configured as a guide post, and the limiting part 50 is configured as a guide groove. In this embodiment, the guide groove can be directly disposed on the housing or disposed on the housing through other structures. Specifically, the housing is provided with a guide frame, and the guide groove is disposed on the guide frame, that is, the limiting part 50 is disposed on the guide frame. Furthermore, in this embodiment, the first rotating shaft 200 is driven to the second massage arm 40 via an axial cam (not shown in the figure). The axial cam is mounted on the first rotating shaft 200 and is constrained to the first rotating shaft 200 by a cam end cap. When the first rotating shaft 200 rotates towards the cam via the drive shaft 10, the second massage arm 40 can swing due to the constraint of the guide post in the guide groove in the housing, thereby enabling the second massage head 41 on the second massage arm 40 to perform massage. Furthermore, in this embodiment, when the massage arm includes the first massage arm 100, the second massage arm 40, the first rotating shaft 200, the second rotating shaft 800, and the eccentric shaft 510, when the first rotating shaft 200 rotates, it enables the first massage arm 100 and the second massage arm 40 to move simultaneously, causing the first massage head 110 and the second massage head 41 to perform massage actions, thus enabling the massager of this application to perform one massage action. When the second rotating shaft 800 rotates, it can only move the first massage arm 100, enabling the massager of this application to perform another massage action. The rotation switching between the first rotating shaft 200 and the second rotating shaft 800 can be achieved through the switching structure 600.

[0080] Furthermore, when the massager of this embodiment includes a position detection component 700, and includes a second rotation shaft 800 and an eccentric shaft 510, the user can adjust the position of the first massage arm 100 according to the position detection component 700. Specifically, the position of the eccentric shaft 510 is detected by the position detection component 700, thereby positioning the position of the first massage arm 100 to adjust the distance between the first massage head 110 and the second massage head 41. Thus, when the massager of this application is applied in a shoulder and neck massage scenario, the distance between the first massage head 110 and the second massage head 41 can be adjusted according to people with different body shapes.

[0081] Furthermore, when the massager of this embodiment includes a position detection component 700 and the first transmission structure 500 is configured as a linear module, the position detection component 700 can detect the position of the second end 420 of the connecting rod 400 to adjust the position of the first massage arm 100, and then position the first massage arm 100 to adjust the distance between the first massage head 110 and the second massage head 41.

[0082] In one embodiment, the first massage arm 100 and the second massage arm 40 are configured as two sets (not shown) and are symmetrically arranged about the left and right sides of the housing. Furthermore, in this embodiment, the first rotating shaft 200 can synchronously drive the two sets of first massage arms 100 and second massage arms 40, and the second rotating shaft 800 can synchronously drive the two sets of first massage arms 100, so that the two sets of first massage arms 100 and second massage arms 40 work synchronously to achieve massage action.

[0083] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
