[0049] The massager is a device for providing self-massage or auxiliary massage, which can relieve muscle tension, relieve pain, improve blood circulation and help relax the body and mind. The massager includes a massage part and a driving part for driving the massage part to work.

[0050] The existing massager has a single massage mode during massage, which cannot meet the needs of users for various massage modes, affecting user experience.

[0051] The massager can solve the problem of single massage mode of the existing massager.

[0052] Please refer to Figure 1 、 Figure 2 In an embodiment of the present application, the massager comprises:

[0053] The first massage arm 100 is provided with first massage heads 110 and a first guiding part 130 in a strip shape. The first massage heads 110 can be spherical heads, cylindrical heads, flat heads, etc. The first massage heads 110 can be detachably connected or tightly connected with each other. The guiding part in a strip shape can be a slot structure, a hole structure, a convex rail structure, etc.

[0054] The first rotating shaft 200 and the third rotating shaft 700, the first rotating shaft 200 drives the first massage arm 100 through the first eccentric structure 300, and the first rotating shaft 200 can rotate relative to the first eccentric structure 300 when driving the first massage arm 100. Further, the third rotating shaft 700 is arranged in parallel with the first rotating shaft 200, the third rotating shaft 700 is slidingly connected to the first guide part 130 and can eccentrically drive the first guide part 130, specifically, the third rotating shaft 700 can eccentrically rotate, that is, the third rotating shaft 700 can rotate around an axis (rotating axis) deviating from its own axis, so as to make eccentric rotating action, when the third rotating shaft 700 makes eccentric rotating, the third rotating shaft 700 can drive the first guide part 130; the third rotating shaft 700 has a transmission state and a positioning state. Specifically, when the third rotating shaft 700 makes eccentric rotating, the third rotating shaft 700 is in the transmission state. The third rotating shaft 700 drives the first massage arm 100 to make eccentric rotating in a direction, while the first rotating shaft 200 rotates and drives the first massage arm 100 through the first eccentric structure 300, wherein when the third rotating shaft 700 rotates in a direction, it should be understood that the third rotating shaft 700 rotates around the rotating axis in a direction; further, the third rotating shaft 700 eccentrically drives the first guide part 130 of the first massage arm 100, while the first rotating shaft 200 drives the first massage arm 100 through the first eccentric structure 300, the first massage arm 100 can reciprocate relative to the first eccentric structure 300 under the driving of the power of the third rotating shaft 700 and the first rotating shaft 200, so that the first massage head 110 can also reciprocate relative to the first eccentric structure 300, thereby enabling the first massage arm 100 to realize a massage mode. Since the third rotating shaft 700 and the first rotating shaft 200 can output different rotating speeds, in order to simulate the effect of knocking massage, the third rotating shaft 700 can output a higher rotating speed, wherein the rotating speed of the third rotating shaft 700 is greater than that of the first rotating shaft 200, under the action of the rotating shafts of the first massage arm 100, an action can be realized at a faster speed, that is, the action of knocking massage is simulated. When the rotating speed of the third rotating shaft 700 is less than that of the first rotating shaft 200, at this time the first guide part 130 can reciprocate relative to the third rotating shaft 700, since the third rotating shaft 700 can rotate, at this time the activity range of the first guide part 130 can be increased compared with the case that the third rotating shaft 700 is stationary, when the activity range of the first guide part 130 is increased, the massage range of the first massage arm 100 can also be increased, thereby realizing another massage mode of the first massage arm 100 of the application, that is, large-range kneading massage.

[0055] In the positioning state, the third rotating shaft 700 can be positioned at a preset position, that is, during the massage operation of the massager, the third rotating shaft 700 is fixed at the preset position, the first rotating shaft 200 drives the first massage arm 100 through the first eccentric structure, and the first guide part 130 can slide reciprocally relative to the third rotating shaft 700. At this time, the first massage arm 100 can slide reciprocally under the drive of the first eccentric structure 300 and the limitation of the third rotating shaft 700, so that the first massage head 110 can also slide reciprocally, thereby realizing another massage mode of the massage arm of the present application, that is, kneading massage.

[0056] Further, the massager further comprises a switching structure 500 for switching the third rotating shaft 700 between the transmission state and the positioning state. In the present embodiment, the first rotating shaft 200 and the third rotating shaft 700 are driven by the same power source, and the switching structure 500 is realized by using a one-way bearing as described below to switch the states, so that the massager reduces the laying of the motor and makes the core structure more compact. It can be understood that in some other embodiments, the first rotating shaft 200 and the third rotating shaft 700 can also be driven by different power sources respectively, that is, the first rotating shaft 200 can be the output shaft of a driving motor, and the third rotating shaft 700 can be the output shaft of an eccentric motor, wherein the rotating speeds of the first rotating shaft 200 and the third rotating shaft 700 can be independently controlled by the respective motors, and the switching structure 500 can be a control button and a control program for controlling the driving motor and the eccentric motor. Specifically, the control program can be a power-on / off circuit for controlling the driving motor and the eccentric motor.

[0057] In an embodiment, referring to Figure 1 、 Figure 3 The massager further comprises a position detection assembly 10 for monitoring the position of the third rotating shaft 700. The position detection assembly 10 is connected with the third rotating shaft 700 and is used to position the third rotating shaft 700 at a preset position. In some embodiments in which the output shaft of an eccentric motor is used as the third rotating shaft 700, the position detection assembly 10 is electrically connected with the eccentric motor. The position detection assembly 10 detects the position of the third rotating shaft 700 and stops the rotation of the eccentric motor when the appropriate position is detected, so that the third rotating shaft 700 is positioned at the position. The massage range of the first massage arm 100 can be changed according to different positions of the third rotating shaft 700.

[0058] It can be understood that in some embodiments, the position detection assembly 10 can also be an angle sensor, through which the position of the third rotating shaft 700 rotating around the rotating axis is obtained, so as to feed back the position to the eccentric motor, and the position of the third rotating shaft 700 can be obtained according to the angle of the third rotating shaft 700, so as to position the third rotating shaft 700 at a suitable position, so as to position the first massage arm 100 at a suitable position, and thus meet the needs of different users.

[0059] In an embodiment, referring to Figure 3 , the position detection assembly 10 can adopt a structure including a Hall plate 12 and two magnets 11, one of which is arranged on the Hall plate 12, and the other magnet 11 is arranged coaxially with the third rotating shaft 700 and can rotate with the third rotating shaft 700, and the Hall plate 12 is used to monitor the position of the magnet 11 rotating with the third rotating shaft 700. Further, when the third rotating shaft 700 rotates, the magnet 11 can rotate with the third rotating shaft 700, and when the magnet 11 rotates, the Hall plate 12 can sense the position of the magnet 11 rotating with the third rotating shaft 700 through the change of the magnetic field generated by the two magnets 11, so as to realize the sensing of the position of the third rotating shaft 700, and thus achieve the purpose of position detection of the third rotating shaft 700.

[0060] In an embodiment, referring to Figure 1 , Figure 2 , the massager further includes a second rotating shaft 400, a first transmission structure 40, the second rotating shaft 400 is arranged parallel to the first rotating shaft 200, and the third rotating shaft 700 is arranged eccentrically on the second rotating shaft 400 through the first transmission structure 40, that is, the axis of the third rotating shaft 700 is different from the axis of the second rotating shaft 400. The second rotating shaft 400 can rotate in a first direction and a second direction, and when the second rotating shaft 400 rotates in the first direction and switches to rotate in the second direction, the switching structure 500 can switch the power transmission between the second rotating shaft 400 and the first transmission structure 40, so as to switch the third rotating shaft 700 between the transmission state and the positioning state. For example, when the second rotating shaft 400 rotates in the first direction, the rotation of the second rotating shaft 400 can drive the third rotating shaft 700 to rotate eccentrically around the axis of the second rotating shaft 400, and when the second rotating shaft 400 rotates in the second direction, the rotation power of the second rotating shaft 400 cannot be transmitted to the third rotating shaft 700, and the third rotating shaft 700 is still positioned at a set position. In this embodiment, the second rotating shaft 400 and the first rotating shaft 200 share the same driving source, and the switching structure 500 is a one-way bearing described below.

[0061] In an embodiment, referring to Figure 4 , Figure 5The first transmission structure 40 comprises a first transmission wheel 41, and the third rotating shaft 700 is eccentrically arranged on the second rotating shaft 400 through the first transmission wheel 41. The switching structure 500 comprises a one-way bearing, and the first transmission wheel 41 is installed on the second rotating shaft 400 through the one-way bearing. When the second rotating shaft 400 rotates in a direction, the one-way bearing is in a loaded state at this time, the one-way bearing drives the first transmission wheel 41, the first transmission wheel 41 can drive the third rotating shaft 700, so that the third rotating shaft 700 rotates around the rotating shaft line, that is, rotates around the axis of the second rotating shaft 400, at this time, the third rotating shaft 700 is in a transmission state. When the second rotating shaft 400 rotates in another direction, the one-way bearing is in an unloaded state at this time, the second rotating shaft 400 does not transmit power to the first transmission wheel 41, at this time, the first transmission wheel 41 does not drive the third rotating shaft 700, so as to position the third rotating shaft 700 at this position, so that the third rotating shaft 700 is in a positioning transmission state. Further, in the embodiment, when the position sensing assembly is arranged on the first transmission structure 40, a magnet is arranged on the first transmission wheel 41 and coaxially arranged with the third rotating shaft 700, the second rotating shaft 400 penetrates the Hall plate 12 and is gap-fitted between the second rotating shaft 400 and the Hall plate 12, that is, the Hall plate 12 does not rotate when the second rotating shaft 400 rotates. The one-way bearing in the design can also be an overrunning clutch of other structures, such as a ratchet overrunning clutch.

[0062] In an embodiment of the design, referring to Figure 1 、 Figure 4 The massager drives the first rotating shaft 200, the second rotating shaft 400 and the third rotating shaft 700 by using the same driving source, specifically, the massager further comprises a driving shaft 600, a second transmission structure 800 and a third transmission structure 900, the driving shaft 600 is in transmission connection with the first rotating shaft 200 through the second transmission structure 800, and the driving shaft 600 is in transmission connection with the second rotating shaft 400 through the third transmission structure 900, wherein the driving shaft 600 can rotate in a first direction and a second direction, and the first rotating shaft 200 and the second rotating shaft 400 can also rotate in corresponding directions through the second transmission structure 800 and the third transmission structure 900.

[0063] In an embodiment, referring to Figure 4 、 Figure 5, the second transmission structure 800 comprises a first transmission part 810 and a second transmission wheel 820 in transmission connection, the drive shaft 600 is in driving connection with the first transmission part 810, and the second transmission wheel 820 is in driving connection with the first rotating shaft 200; the third transmission structure 900 comprises a second transmission part 910 and a third transmission wheel 920 in transmission connection, the second transmission part 910 is in driving connection with the drive shaft 600, and the third transmission wheel 920 is in driving connection with the second rotating shaft 400, wherein the first transmission part 810 and the second transmission part 910 can be configured as transmission gears, when the transmission gears are transmission helical gears, the second transmission wheel 820 and the third transmission wheel 920 correspond to the transmission helical gears, at this time, the axis of the drive shaft 600 is arranged perpendicularly to the axis of the first rotating shaft 200. When the transmission gears are configured as transmission spur gears, wherein the axis of the drive shaft 600 is arranged in parallel to the axis of the first rotating shaft 200, at this time, between the first transmission part 810 and the second transmission wheel 820 and between the second transmission part 910 and the third transmission wheel 920, transmission can be completed through a synchronous belt, a chain or a transmission gear, and at the same time, according to the transmission ratio in the transmission process, the speed and the torque output by the second transmission structure 800 and the third transmission structure 900 can be adjusted.

[0064] Further, in the embodiment, with reference to Figure 4 、 Figure 5 , the drive shaft 600 is provided with a worm segment, the first transmission part 810 and the second transmission part 910 are both configured as the worm segment on the drive shaft 600, wherein the worm segment can be directly formed on the drive shaft 600, in other embodiments, the drive shaft 600 can also be provided with the worm segment through the way of sleeving the worm, the worm segment is in driving connection with the second transmission wheel 820 and the third transmission wheel 920, at this time, the second transmission wheel 820 and the third transmission wheel 920 can be configured as turbines or other gear structures that can be configured with the worm segment, when the transmission is realized through the turbine worm, the second transmission structure 800 and the third transmission structure 900 have the function of self-locking, that is, the turbine can be driven to rotate by the worm, but the turbine cannot drive the worm to rotate.

[0065] In an embodiment, with reference to Figure 1 、 Figure 3 , the first eccentric structure 300 comprises an eccentric wheel 310, the eccentric wheel 310 is in transmission connection with the first massage arm 100, the first massage arm 100 can rotate relative to the eccentric wheel 310, the first massage arm 100 is provided with a mounting hole 120, and the first eccentric wheel 310 is arranged in the mounting hole 120, when the first rotating shaft 200 drives the first eccentric wheel 310 to eccentrically rotate, the first eccentric wheel 310 can drive the first massage arm 100 to move, and at the same time, the first massage arm 100 can rotate relative to the first eccentric wheel 310 through the mounting hole 120.

[0066] In an embodiment, referring to Figure 1 , the first massage arm 100 is externally provided with a guide frame, the guide frame is internally provided with a guide hole, the first guide part 130 is configured as the guide hole, and the third rotating shaft 700 is arranged through the guide hole at this time; further, in this embodiment, the distance between the rotating circumference of the third rotating shaft 700 and the first eccentric structure 300 is less than the distance between the rotating circumference of the third rotating shaft 700 and the first massage head 110, and the rotating circumference of the third rotating shaft 700 is arranged close to the first eccentric structure 300 at this time; in this way, the third rotating shaft 700 drives the first guide part 130 in the process of rotating, and since the rotating circumference of the third rotating shaft 700 is arranged close to the first eccentric structure 300 at this time, the first guide part 130 drives the first massage arm 100, and the third rotating shaft 700 can increase the rotating range of the first massage arm 100 relative to the first eccentric structure 300 when rotating a relatively small stroke.

[0067] In an embodiment, the massager further comprises a housing (not shown), a second massage arm 20, a second massage head 21 provided on the second massage arm 20, and a limiting part 30, the housing is provided with the second guide part 22 corresponding to the limiting part 30, the extending direction of the second guide part 22 is consistent with the extending direction of the first rotating shaft 200, the first rotating shaft 200 is drivingly connected with the second massage arm 20 through an axial cam, and the limiting part 30 can reciprocate in the second guide part 22 when the first rotating shaft 200 drives the second massage arm 20, so as to make the second massage arm 20 reciprocate. Further, in the embodiment, the second guide part 22 is configured as a guide column, and the limiting part 30 is configured as a guide groove. In the embodiment, the guide groove can be directly provided on the housing or provided on the housing through other structures. Specifically, the housing is provided with a guide frame, the guide groove is provided on the guide frame, that is, the limiting part 30 is provided on the guide frame. Further, in the embodiment, the first rotating shaft 200 is drivingly connected with the second massage arm 20 through an axial cam (not shown in the figure), the axial cam is mounted on the first rotating shaft 200, and the axial cam drives the second massage arm 20 to rotate in the process that the driving shaft 600 drives the first rotating shaft 200. Due to the restriction of the guide column in the guide groove in the housing, the left and right second massage arms 20 can approach or move away from each other, so that the second massage head 21 on the second massage arm 20 realizes kneading massage action. Further, in the embodiment, when the massage arm comprises the first massage arm 100, the second massage arm 20, the first rotating shaft 200, the second rotating shaft 400, and the third rotating shaft 700, when the first rotating shaft 200 rotates and the third rotating shaft 700 is in a positioning state, the first massage arm 100 and the second massage arm 20 on the same side of the massager approach or move away from each other, the left and right second massage arms 20 approach or move away from each other, so that the first massage head 110 and the second massage head 21 perform massage action at approximately the same rhythm, so that the massager of the application performs one kind of massage action. When the first rotating shaft 200 and the third rotating shaft 700 are both in a rotating state, the second massage arm 20 swings under the drive of the first rotating shaft 200, and the first massage arm 100 swings under the common rotation of the first rotating shaft 200 and the third rotating shaft 700. Since the third rotating shaft 700 can output faster rotating speed, the swinging speed of the first massage arm 100 is greater than that of the second massage arm 20. Therefore, the massager slowly kneads under the action of the left and right second massage arms 200, and the first massage arm 100 swings quickly, which presents a knocking massage effect to the user, so that the massager of the application performs another kind of massage action. The rotation switching of the first rotating shaft 200 and the second rotating shaft 400 can be realized through the switching structure 500.

[0068] Further, when the massager of the embodiment includes the position detection assembly 10, the user can adjust the position of the first massage arm 100 according to the position detection assembly 10, specifically, the position of the third rotating shaft 700 is detected through the position detection assembly 10, so that the position of the first massage arm 110 is positioned, to adjust the distance between the first massage head 110 and the second massage head 21, so that when the massager of the application is applied in the shoulder and neck massage scenario, the distance between the first massage head 110 and the second massage head 21 can be adjusted according to different body postures of the crowd.
