[0067] The utility model provides a kind of massager to solve the problem of single massage mode of existing massager.

[0068] Please refer to Figure 1 、 Figure 2 In an embodiment of the utility model, the massager comprises:

[0069] The shell 30 comprises:

[0070] The first massage arm 100 and the first rotating shaft 200, the first massage arm 100 is provided with the first massage head 110 and the first limiting part 120 in the shape of a long strip;Wherein the first massage head 110 can be spherical head, cylindrical head, flat head and the like, and the first massage head 110 and the first massage head 110 can be detachably connected, and can also be fastened connection, further, the first limiting part 120 in the shape of a long strip can be the long strip-shaped convex structure (see Figure 2 、 Figure 3), and can also be a recessed groove structure (not shown) of the first massage arm 100. The first rotating shaft 200 drives the first massage arm 100 through the first eccentric structure 10, and the first massage arm 100 can rotate relative to the first eccentric structure 10. Further, the first eccentric structure 10 includes a second eccentric wheel 11, the first rotating shaft 200 is drivingly connected with the second eccentric wheel 11, and the first massage arm 100 is sleeved with the second eccentric wheel 11. A first mounting hole 130 (see Figure 2 ) is formed in the first massage arm 100, and the second eccentric wheel 11 is arranged in the first mounting hole 130. When the first rotating shaft 200 drives the second eccentric wheel 11 to eccentrically rotate, the second eccentric wheel 11 can drive the first massage arm 100 to move through the first mounting hole 130, and the first massage arm 100 can rotate relative to the second eccentric wheel 11 through the first mounting hole 130. In some embodiments, the first rotating shaft 200 is driven by a driving motor through a transmission structure. It can be understood that in other embodiments, the first rotating shaft 200 can be an output shaft of the driving motor.

[0071] The first guide part 400 is slidingly arranged in the shell 30, wherein the shell 30 is provided with a track structure 31 (see Figure 8 、 Figure 9 ) relative to the first guide part 400, and the first guide part 400 is slidingly arranged in the track structure 31, so as to be slidingly arranged in the shell 30. Further, the track structure 31 can be a groove structure or a convex rail structure.

[0072] The sliding direction of the first guide part 400 is arranged at a preset angle relative to the axis of the first rotating shaft 200, and further, the sliding direction of the first guide part 400 is arranged at a ninety-degree angle relative to the axis of the first rotating shaft 200. In other embodiments, the sliding direction of the first guide part 400 can also be arranged at other angles relative to the axis of the first rotating shaft 200, such as eighty-five degrees. That is, the first rotating shaft 200 extends along the length direction of the massager, and the first guide part 400 extends along the width direction of the massager. Such design can effectively arrange the structure of the core as a compact type, effectively utilize the space of the shell, and be beneficial to the miniaturization design of the massager.

[0073] The first limiting part 120 is in sliding fit with the first guide part 400 and is limited in the first guide part 400, so that the first limiting part 120 can move along with the first guide part 400, that is, the first limiting part 120 can slide relative to the first guide part 400. Further, in the embodiment, the first guide part 400 and the first limiting part 120 can adopt the following structure: the first guide part 400 is provided with a driving groove 410, and the first limiting part 120 is configured as a long strip-shaped protruding structure, wherein the protruding structure is inserted into the driving groove 410 (see Figure 2 , Figure 3 ). When the first guide part 400 moves back and forth, the driving groove 410 on the first guide part 400 can drive the first limiting part 120 to move together, and the first limiting part 120 can slide up and down in the driving groove 410 when moving.

[0074] Further, the first guide part 400 and the first limiting part 120 can also adopt the following structure: the first guide part 400 is provided with a protrusion 420 (see Figure 15 ), and the first limiting part 120 is configured as a protruding structure, wherein the protruding structure is provided with a driven groove or a driven hole 121, and the protrusion 420 is inserted into the driven groove or the driven hole 121 (see Figure 15 ). When the first guide part 400 moves, the protrusion 420 can drive the first limiting part 120 to move through the driven groove or the driven hole 121, and the driven groove or the driven hole 121 can move back and forth relative to the protrusion 420 on the first guide part 400.

[0075] The transmission mechanism 500 is in driving connection with the first guide part 400, so that the first guide part 400 has a moving state and a static state. In some embodiments, the transmission mechanism 500 can be a linear reciprocating driving module, such as a cylinder linear reciprocating driving assembly (not shown), an electric telescopic rod linear reciprocating driving assembly (not shown), a motor connecting rod slider structure (not shown), etc. The first guide part 400 is driven to move back and forth by the above-mentioned mechanism, so that the first guide part 400 is in a moving state. By stopping the motor or the cylinder in the above-mentioned mechanism, the first guide part 400 is in a static state.

[0076] Specifically, in the moving state, the transmission mechanism 500 can transmit power to the first guide part 400, so that the first guide part 400 can slide back and forth relative to the housing 30. The first guide part 400 drives the first limiting part 120, and the first rotating shaft 200 drives the first massage arm 100 through the first eccentric structure 10. The first massage arm 100 makes a reciprocating swinging motion relative to the first eccentric structure 10 under the joint action of the first guide part 400 and the first eccentric structure 10.

[0077] In the static state, the transmission mechanism 500 is used to position the first guide part 400 at a preset position, wherein the preset position can be determined according to the use requirement, the first rotating shaft 200 drives the first massage arm 100 through the first eccentric structure 10, and the first guide part 400 limits the movement range of the first limiting part 120. In the static state, the first guide part 400 limits the movement of the first limiting part 120, so that the first limiting part 120 reciprocates relative to the first guide part 400, that is, the first massage arm 100 reciprocates under the driving action of the first eccentric structure 10 and the limiting action of the first guide part 400.

[0078] It should be noted that the range of the swing track of the first massage head 110 is different in the movement state and in the static state, and the range of the swing track of the first massage head 110 is different in different preset positions in the static state. Through the above-mentioned arrangement, different massage track ranges can be provided to meet the different requirements of users, thereby solving the problem of single massage mode of the existing massage equipment.

[0079] The switching structure 600 is used to switch the first guide part 400 between the movement state and the static state, wherein the switching structure 600 can be a control button and a control program for starting and stopping the transmission mechanism 500. Specifically, the control program can be a control circuit, and the transmission mechanism 500 can be positioned at different positions according to different stop positions of the transmission mechanism 500, so as to adjust the massage range of the first massage head 110 at different positions. Further, the transmission mechanism 500 is controlled by the switching structure 600 to switch the first guide part 400 between the movement state and the static state.

[0080] In an embodiment, referring to Figure 1 The massager further comprises a driving shaft 700, which is drivingly connected with the first rotating shaft 200 and the transmission mechanism 500. The driving shaft 700 can transmit power to the first guide part 400 through the transmission mechanism 500. The driving shaft 700 can be an output shaft of a driving motor, so that the massager of the present application can only be provided with one driving motor, and the first rotating shaft 200 and the transmission mechanism 500 are driven to work by the driving motor.

[0081] The driving shaft 700 can rotate in a first direction and a second direction; when the driving shaft 700 switches between the first direction and the second direction, the switching structure 600 can switch the power transmission between the driving shaft 700 and the first guide part 400, so as to switch the first guide part 400 between the moving state and the static state, that is, when the driving shaft 700 rotates in one direction, the switching structure 600 can make the power of the driving shaft 700 transmitted to the first guide part 400 through the transmission mechanism 500, so as to make the first guide part 400 in the moving state. When the driving shaft 700 rotates in the other direction, the switching structure 600 makes the power of the driving shaft 700 unable to be transmitted to the first guide part 400, so as to make the first guide part 400 in the static state. Further, the power of the driving shaft 700 unable to be transmitted to the first guide part 400 can be that the power of the driving shaft 700 cannot be transmitted to the transmission mechanism 500, so that the power cannot be transmitted to the first guide part 400, or that the transmission mechanism 500 cannot complete the power transmission, so that the power of the driving shaft 700 cannot be transmitted to the first guide part 400.

[0082] Further, with reference to Figure 1 、 Figure 14 In the embodiment, the driving shaft 700 is in transmission connection with the first rotating shaft 200 through the fourth transmission structure 40, wherein the fourth transmission structure 40 comprises a fourth transmission wheel 41 in transmission connection with the driving shaft 700, and the fourth transmission wheel 41 is installed on the first rotating shaft 200, so that when the fourth transmission wheel 41 rotates, the first rotating shaft 200 can also rotate. Meanwhile, in the embodiment, the fourth transmission wheel 41 can be configured as a turbine, and at this time, a worm or a worm segment is installed on the driving shaft 700, and at this time, the driving shaft 700 and the fourth transmission wheel 41 can be in transmission through a worm and a gear, so that the axis of the driving shaft 700 is perpendicular to the axis of the first rotating shaft 200. In other embodiments, the axis of the driving shaft 700 can be parallel to the axis of the first rotating shaft 200, and at this time, the driving shaft 700 can be coaxially arranged with the first rotating shaft 200, so that the fourth transmission structure 40 can be a connecting structure for connecting two shafts, and the connecting mechanism can be a shaft coupling or the like.

[0083] In an embodiment, with reference to Figure 1 、 Figure 3 、 Figure 4 The transmission mechanism 500 can adopt the following structure, that is, the transmission mechanism 500 comprises a reciprocating screw rod 510 (see Figure 6 ) and a sliding ring 520 (see Figure 5), the sliding ring 520 is fixed to the first guide part 400, wherein the sliding ring 520 is in sliding fit with the reciprocating screw rod 510, and the transmission mechanism 500 further comprises a limiting plate 560 (see Figure 7 ), when the reciprocating screw rod 510 rotates, the sliding ring 520 can reciprocate along the axis of the reciprocating screw rod 510, and when the sliding ring 520 reciprocates, the first guide part 400 connected with the sliding ring 520 can reciprocate, and further, in the embodiment, the axis direction of the reciprocating screw rod 510 is parallel to the moving direction of the first guide part 400. The driving shaft 700 is connected with the reciprocating screw rod 510 through the first transmission structure 530, the driving shaft 700 drives the reciprocating screw rod 510 to rotate through the first transmission structure 530, so that the sliding ring 520 reciprocates along the extension direction of the reciprocating screw rod 510, and at the same time, the first guide part 400 reciprocates in the housing 30.

[0084] Further, referring to Figure 1 , the switching structure 600 can switch the power transmission between the driving shaft 700 and the first transmission structure 530, so as to make the reciprocating screw rod 510 rotate or stop. When the driving shaft 700 transmits power to the first transmission structure 530, the first transmission structure 530 transmits power to the reciprocating screw rod 510, so that the reciprocating screw rod 510 rotates, and the reciprocating screw rod 510 can drive the sliding ring 520 to reciprocate along the axis of the reciprocating screw rod 510, so as to drive the first guide part 400 to reciprocate, at this time, the transmission mechanism 500 is in a moving state. When the driving shaft 700 does not transmit power to the first transmission structure 530 under the action of the switching structure 600, at this time, the reciprocating screw rod 510 stops, the sliding ring 520 is positioned on the reciprocating screw rod 510 and does not move, so that the first guide part 400 is also positioned and does not move, at this time, the transmission mechanism 500 is in a static state.

[0085] However, the design is not limited to this, in other embodiments, the switching structure 600 can switch the power transmission between the first transmission structure 530 and the reciprocating screw rod 510, so as to make the reciprocating screw rod 510 rotate and stop, so that the transmission mechanism 500 is in a moving state and a static state, so as to achieve the purpose of cutting off the power transmission between the driving shaft 700 and the first guide part 400.

[0086] In an embodiment, referring to Figure 12 , Figure 13 , the first transmission structure 530 comprises a first transmission wheel 531 and a second transmission wheel 532 in transmission connection, the driving shaft 700 is in driving connection with the first transmission wheel 531, and the second transmission wheel 532 is in driving connection with the reciprocating screw rod 510; in the embodiment, the first transmission wheel 531 and the second transmission wheel 532 can adopt a synchronous belt structure (seeFigure 13 ), or chain structure, or gear structure (see Figure 12 ) and so on. Further, the switching structure 600 comprises a first one-way bearing 610, the first transmission wheel 531 is installed on the driving shaft 700 through the first one-way bearing 610, when the driving shaft 700 rotates in a direction, the first one-way bearing 610 is in a loaded state, at this time the driving shaft 700 can drive the first transmission wheel 531, so that the first transmission wheel 531 drives the second transmission wheel 532, thereby driving the reciprocating lead screw 510 to rotate. When the driving shaft 700 rotates in the other direction, the first one-way bearing 610 is in an unloaded state, at this time the driving shaft 700 does not drive the first transmission wheel 531, so that the reciprocating lead screw 510 is in a state of stopping rotating.

[0087] However, the design is not limited to this, in other embodiments, the second transmission wheel 532 is installed on the reciprocating lead screw 510 through the first one-way bearing 610, and for the same reason, when the second transmission wheel 532 rotates in a direction, the first one-way bearing 610 is in a loaded state and can drive the reciprocating lead screw 510 to rotate. When the second transmission wheel 532 rotates in the other direction, the first one-way bearing 610 is in an unloaded state and cannot drive the reciprocating lead screw 510 to rotate.

[0088] In an embodiment, referring to Figure 14 , the transmission mechanism 500 can also adopt the following structure, the transmission mechanism 500 comprises a second rotating shaft 540, a second transmission structure 550 and a third transmission structure 570, the second rotating shaft 540 is arranged in parallel with the first rotating shaft 200, the second transmission structure 550 is in transmission connection with the driving shaft 700 and the second rotating shaft 540, and the third transmission structure 570 is in transmission connection with the second rotating shaft 540 and the first guide part 400.

[0089] The switching structure 600 can switch the power transmission between the driving shaft 700 and the first guide part 400 by switching the power transmission between the driving shaft 700 and the second rotating shaft 540; specifically, when the switching structure 600 switches the power transmission between the driving shaft 700 and the second rotating shaft 540, it can switch the power transmission between the driving shaft 700 and the second transmission structure 550, or the power transmission between the second transmission structure 550 and the second rotating shaft 540.

[0090] The design is not limited to this, and in other embodiments, the switching structure 600 can also switch the power transmission between the second rotating shaft 540 and the first guide part 400 to switch the power transmission between the driving shaft 700 and the first guide part 400. Specifically, when the switching structure 600 switches the power transmission between the second rotating shaft 540 and the first guide part 400, it can switch the power transmission between the second rotating shaft 540 and the third transmission structure 570, and also switch the power transmission between the third transmission structure 570 and the first guide part 400.

[0091] In an embodiment, referring to Figure 14 , the second transmission structure 550 includes a third transmission wheel 551 that is drivingly connected to the second rotating shaft 540 and drivingly connected to the driving shaft 700. Further, the driving shaft 700 is provided with a worm segment (see Figure 14 illustrated), and the worm segment of the driving shaft 700 is drivingly connected to the third transmission wheel 551. In other embodiments, the driving shaft 700 can also be provided with a transmission gear. When the driving shaft 700 is provided with a transmission gear, the third transmission wheel 551 is also configured as a transmission gear. The two transmission gears can be directly meshing transmission, or indirectly transmission through structures such as synchronous belts, chain wheels, etc.

[0092] Further, in this embodiment, referring to Figure 14 , Figure 16 , the third transmission structure 570 includes a first eccentric wheel 571 provided on the second rotating shaft 540 and a connecting rod 572 sleeved on the first eccentric wheel 571. The connecting rod 572 is rotatably connected to the first eccentric wheel 571 and the first guide part 400. Further, in this embodiment, the connecting rod 572 is configured as a plate-shaped structure, and the connecting rod 572 can rotate relative to the first eccentric wheel 571. When the first eccentric wheel 571 rotates, the eccentric wheel can drive the connecting rod 572, thereby driving the first guide part 400 to reciprocate through the connecting rod 572.

[0093] The switching structure 600 includes a second one-way bearing 620 (see Figure 14 ), and the third transmission wheel 551 is installed on the second rotating shaft 540 through the second one-way bearing 620. Further, in this embodiment, when the third transmission wheel 551 rotates in one direction, the second one-way bearing 620 is in a loaded state. At this time, the third transmission wheel 551 can transmit power to the second rotating shaft 540 through the second one-way bearing 620. When the third transmission wheel 551 rotates in the other direction, the second one-way bearing 620 is in an unloaded state. At this time, the power of the third transmission wheel 551 cannot be transmitted to the second rotating shaft 540.

[0094] Further, in an embodiment, the one-way bearing described above can adopt other structures of overrunning clutches, such as a ratchet overrunning clutch, to achieve the state that the clutch is in load when rotating in one direction and can transmit power, and the state that the clutch is in empty load when rotating in the other direction and cannot transmit power.

[0095] In an embodiment, referring to Figure 9 、 Figure 10 、 Figure 11 , the massager further comprises a position detection assembly 800 for detecting the position of the first guide part 400, the position detection assembly 800 is connected with the transmission mechanism 500, and the transmission mechanism 500 can position the first guide part 400 at a preset position. Further, in the embodiment, the position detection assembly 800 can adopt a linear displacement monitoring assembly to detect the position of the first guide part 400 and cooperate with the transmission mechanism 500 to position the first guide part 400. Specifically, when the sliding ring 520 or the first eccentric wheel 571 stops and is positioned, the first guide part 400 can also be positioned at this time. Further, according to the position where the sliding ring 520 stops and is positioned or the position where the first eccentric wheel 571 stops and is positioned, the first guide part 400 can be positioned at different positions, so that the massage position of the first massage arm 100 can be changed following the different positions of the first guide part 400.

[0096] In an embodiment, referring to Figure 9 , the position detection assembly 800 comprises two Hall sensors 820 arranged along the moving path of the first guide part 400 and a magnet 810 arranged on the first guide part 400 and located between the two Hall sensors 820. When the first guide part 400 reciprocates, the two Hall sensors 820 can detect the position of the magnet 810 arranged on the first guide part 400. Specifically, when the magnet 810 arranged on the first guide part 400 reciprocates, the Hall sensor 820 can sense the change of the magnetic field, so as to sense the position of the magnet 810 reciprocating with the first guide part 400, and further reflect the position of the first guide part 400.

[0097] In an embodiment, referring to Figure 1 、 Figure 3 、 Figure 14The massager further comprises a second massage arm 900, a second massage head 910 arranged on the second massage arm 900, and a second limiting part 920, the shell 30 is provided with the second guide part 20 corresponding to the limiting part, the first rotating shaft 200 is drivingly connected with the second massage arm 900, and when the first rotating shaft 200 drives the second massage arm 900, the limiting part can reciprocatingly slide in the second guide part 20, so that the second massage arm 900 reciprocatingly swings, and the second guide part 20 extends along the axial direction of the first rotating shaft 200. Further, in the embodiment, the second guide part 20 is configured as a guide column, and the second limiting part 920 is configured as a guide groove. In the embodiment, the guide groove can be directly arranged on the shell 30 or arranged on the shell 30 through other structures.

[0098] Further, in the embodiment, the first rotating shaft 200 is drivingly connected with the second massage arm 900 through the axial cam 300, the axial cam 300 is mounted on the first rotating shaft 200, the axial cam 300 is limited on the first rotating shaft 200 through the cam end cover, and when the driving shaft 700 rotates the cam 300, the second massage arm 900 can swing under the limitation of the guide column in the guide groove in the shell 30, so that the second massage head 910 on the second massage arm 900 massages. Further, in the embodiment, when the massage arm comprises the first massage arms 100 on the left and right sides, the second massage arms 900 on the left and right sides, the first rotating shaft 200, and the second rotating shaft 540, when the first rotating shaft 200 rotates and the first guide part 400 is in a static state, the first massage arms 100 and the second massage arms 900 simultaneously move, the second massage arms 900 on the left and right sides can swing in a manner of approaching or moving away from each other, and the first massage arms 100 reciprocatingly swing around the first rotating shaft 200, so that the first massage arms 100 and the second massage arms 900 on the same side approach or move away from each other, because the first massage arms 100 and the second massage arms 900 move under the action of the first rotating shaft 200, they move at substantially the same speed, and perform kneading massage, so that the massager performs a kind of massage action. When the first rotating shaft 200 rotates and the first guide part 400 is in a moving state, due to the arrangement of the transmission structure, the rotating speed of the first rotating shaft 200 is much smaller than that of the second rotating shaft 540, so the swinging speed of the second massage arm 900 is much greater than that of the first massage arm 100, at this time, the first massage heads 110 on the two sides approach or move away from each other at a slower speed, and the second massage arms 900 reciprocatingly swing at a faster speed, forming an action similar to knocking, so that the massager can perform compound massage of kneading and knocking.

[0099] In an embodiment, the second guide part 20 is fixed with the first guide part 400, that is, the second guide part 20 can move or stop following the first guide part 400, so in the embodiment, the first guide part 20 adopts the structure that a protrusion 420 (see Figure 15 ) is arranged on the first guide part 400, at this time when the first guide part 400 is in a static state, the first limiting part 120 can reciprocate slidingly relative to the protrusion 420. When the first guide part 400 is in a moving state, the protrusion 420 can drive the first limiting part 120 to move, so that the first limiting part 120 can drive the first massage arm 100 to swing at a high frequency, forming a massage action similar to knocking. At the same time, the second massage arm 900 can swing at a high frequency under the action of the second guide part 20, so that the second massage arm 900 performs a reciprocating knocking action.

[0100] In an embodiment, referring to Figure 10 、 Figure 11 , when the massager comprises the position detection assembly 800, the first massage arm 100, the second massage arm 900 and the like, the position of the first massage arm 100 is adjusted through the position detection assembly 800, and then the position of the first massage head 110 is adjusted, so as to adjust the distance between the first massage head 110 and the second massage head 910. When the massager of the application is applied to massage in a neck and shoulder situation, the distance between the first massage head 110 and the second massage head 910 can be adjusted according to different postures of the user, so that the massage force of the massage head can be appropriate when the massager massages different postures of people, and the problem of reduced massage force caused by the distance between the massage head and the user being too far can be avoided.

[0101] The above only describes exemplary embodiments of the application, and does not limit the patent scope of the application, and any equivalent structural transformation or direct / indirect application in other related technical fields within the technical concept of the application is included in the patent protection scope of the application.
