Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a massage mechanism and a massage device. Background Technology

[0002] Whether it's prolonged desk work or physical labor, people's lower back muscles are prone to varying degrees of fatigue over time. To improve this situation, various massage devices have begun to appear on the market, among which are massage devices with rotating massage heads. The mechanism of these massage devices can drive the massage heads to rotate unidirectionally within a certain range, thereby mimicking the massage techniques of traditional Chinese medicine, such as pushing and pressing, and is therefore highly sought after by users.

[0003] However, to prevent the rotating massage heads from getting tangled in clothing, these types of massagers usually have an elastic cloth installed to separate the massage heads from the clothing. But this not only affects the massage feel of the massager, resulting in a poor massage experience, but the elastic cloth is also prone to wear and tear after a period of use, affecting the lifespan of the massager. Utility Model Content

[0004] In view of this, the present invention provides a massage mechanism and a massager to solve the problem that in the prior art, massagers usually have an elastic cloth installed to separate the massage head from clothing. However, this not only affects the massage feel of the massager, resulting in a poor massage experience, but also the elastic cloth is prone to wear after a period of use, affecting the service life of the massager.

[0005] To achieve one, some, or all of the above objectives or other objectives, this utility model proposes a massage mechanism, including a base, a first massage device, and a driving component.

The first massage device includes a guide structure, a rack, a slider, a follower gear, and a transmission assembly. The guide structure and the rack are both fixed on the base and are arranged along the length direction of the base. The slider is slidably connected to the guide structure. The follower gear is rotatably connected to the slider and meshes with the rack. The driving component can drive the slider to reciprocate along the length direction of the guide structure through the transmission assembly.

[0006] Preferably, the transmission assembly includes a threaded rod, which is rotatably mounted on the base and arranged in the same direction as the guide structure. The driving member can drive the threaded rod to rotate, thereby driving the slider to slide back and forth along the length direction of the guide structure.

[0007] Preferably, the transmission assembly further includes a driven worm gear, the threaded rod is a transmission worm, the driven worm gear is coaxially fixed at one end of the follower gear and meshes with the transmission worm.

[0008] Preferably, the first massage device further includes a reduction gear set, the driving component is a motor, and the output shaft of the motor is driven to a threaded rod through the reduction gear.

[0009] Preferably, the guide structure is a slide bar, and there are two slide bars distributed along the width direction of the base, and the slider is slidably sleeved on the two slide bars.

[0010] Preferably, the massage mechanism further includes two boundary sensors and a trigger. The two boundary sensors are fixedly disposed on the outer side wall of the base and distributed along the length of the guide structure. The trigger is disposed on the slider. The trigger can slide with the slider to approach any one of the boundary sensors. When the trigger is adjacent to a boundary sensor, it can trigger the boundary sensor.

[0011] Preferably, the massage mechanism further includes a positioning sensor, which is fixedly disposed on the outer wall of the base and located between two boundary sensors. The trigger can slide closer to the positioning sensor with the slider. When the trigger is adjacent to the positioning sensor, it can trigger the positioning sensor.

[0012] Preferably, the boundary sensing element and the positioning sensing element are both Hall sensors, and the trigger element is a magnet.

[0013] Preferably, the massage mechanism further includes a second massage device. The motor is centrally located on the base and is positioned along the width of the base. The first massage device is located at the left end of the base, and the second massage device is located at the right end of the base. The second massage device and the first massage device are symmetrical about the axis of the motor. Two clearance openings are symmetrically opened at both ends of the base, and the clearance openings are arranged in the same direction as the guide structure.

[0014] A massager includes a massage mechanism, an outer cover, two elastic fabrics, two sets of massage heads, and a pair of straps. The outer cover is spliced ​​with a base to form a cavity for accommodating a first massage device, a second massage device, and a drive component. The two elastic fabrics are disposed on the inner sidewall of the base and cover the clearance openings.

The drive component will drive the slider to slide towards one end of the guide structure through the transmission assembly. At this time, the follower gear, which moves with the slider, will roll and rotate under the action of the rack, thereby driving the massage head to rotate forward. When the slider slides to one end of the guide structure, the drive component will drive the slider to slide towards the other end of the guide structure through the transmission assembly, and the follower gear will also roll and rotate in reverse under the action of the rack, thereby driving the massage head to rotate in reverse. The massage head slides back and forth in a straight line while rotating, and the direction of rotation switches synchronously with the direction of sliding. This prevents the massage head from rotating in one direction and getting tangled in clothing. Therefore, there is no need to add an elastic cloth to separate the massage head from clothing, effectively improving the massage feel, ensuring the massage experience, avoiding the use of consumable parts such as elastic cloth, and extending the service life of the massager.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figure 1-5As shown, a massage mechanism includes a base 1, a first massage device 2, and a drive unit 3. The first massage device 2 and the drive unit 3 are both disposed on the outer wall of the base 1. The first massage device 2 includes a guide structure 20, a rack 21, a slider 22, a follower gear 23, and a transmission assembly 24. The guide structure 20 and the rack 21 are both fixed to the base 1 and are arranged along the length direction of the base 1. The slider 22 is slidably connected to the guide structure 20. The follower gear 23 is rotatably connected to the slider 22 and meshes with the rack 21. The drive unit 3 can drive the slider 22 to reciprocate along the length direction of the guide structure 20 via the transmission assembly 24. In use, the follower gear 23 can be coaxially connected to the massage head 7, and the drive unit 3 will drive the slider 22 towards the guide structure 20 via the transmission assembly 24. When one end of structure 20 slides, the follower gear 23, which moves with the slider 22, will roll and rotate under the action of rack 21, thereby driving the massage head 7 to rotate forward. When the slider 22 slides to one end of guide structure 20, the drive component 3 will drive the slider 22 to slide towards the other end of guide structure 20 through transmission component 24. The follower gear 23 will also roll and rotate in reverse under the action of rack 21, thereby driving the massage head 7 to rotate in reverse. The massage head 7 slides back and forth in a straight line while rotating, and the direction of rotation switches synchronously with the direction of sliding. This can prevent the massage head 7 from rotating in one direction and getting tangled in clothing. Therefore, there is no need to add an elastic cloth 6 to separate the massage head 7 from clothing, which effectively improves the massage feel, ensures the massage experience, avoids the use of consumable accessories such as elastic cloth 6, and extends the service life of the massager.

[0029] In one embodiment, the driving component 3 is a motor, and the transmission assembly 24 includes an eccentric wheel and a connecting rod. The eccentric wheel is rotatably mounted on the base 1 and is arranged in the same direction as the follower gear 23. The motor is driven by the eccentric wheel. One end of the connecting rod is hinged to the eccentric end of the eccentric wheel, and the other end of the connecting rod is hinged to the slider 22. The motor can drive the eccentric wheel to rotate, and the eccentric wheel will drive the connecting rod to swing, thereby pushing and pulling the slider 22 through the connecting rod, so that the slider 22 slides back and forth along the guide structure 20 (not shown in the figure).

[0030] In one embodiment, the guide structure 20 is a groove, and the slider 22 is engaged in the groove and can slide along the length of the groove (not shown in the figure).

[0031] Furthermore, the transmission assembly 24 includes a threaded rod 241, which is rotatably mounted on the base 1 and arranged in the same direction as the guide structure 20. The drive member 3 can drive the threaded rod 241 to rotate, thereby driving the slider 22 to slide back and forth along the length direction of the guide structure 20.

[0032] In one embodiment, the driving component 3 is a motor, and the threaded rod 241 is coaxially fixed on the output shaft of the motor. The motor and the guide structure 20 are arranged in the same direction. The threaded rod 241 is threadedly connected to the slider 22. The sliding direction of the slider 22 is adjusted by changing the rotation direction of the motor, so as to realize the reciprocating sliding of the slider 22. The forward and reverse rotation of the motor is controlled by the corresponding control chip (not shown in the figure). Both the control chip and the motor can be purchased through market channels and will not be described in this embodiment.

[0033] Furthermore, the transmission assembly 24 also includes a driven worm gear 242, the threaded rod 241 is a transmission worm, the driven worm gear 242 is coaxially fixed at one end of the follower gear 23 and meshes with the transmission worm.

[0034] Furthermore, the first massage device 2 also includes a reduction gear set 25, and the driving component 3 is a motor. The output shaft of the motor is driven and connected to the threaded rod 241 through the reduction gear set 25.

[0035] Specifically, the output shaft of the motor is driven to the reduction gear set 25 via a worm and a worm wheel, and the reduction gear set 25 is driven to the transmission worm via a helical gear.

[0036] In this embodiment, the motor drives the transmission worm gear to rotate at low speed through the reduction gear set 25, thereby driving the driven worm wheel 242 through the transmission worm gear. The driven worm wheel 242 drives the follower gear 23 to roll at low speed along the rack 21, so that the corresponding massage head 7 moves and rotates at low speed, so as to imitate the massage techniques of traditional Chinese medicine to massage the user's muscles. At the same time, the motor directly drives the follower gear 23 through the transmission worm gear, which also effectively shortens the transmission chain, reduces power loss, and makes the movement and rotation of the massage head 7 more powerful, thus improving the massage experience.

[0037] Furthermore, the guide structure 20 is a slide bar, with two slide bars distributed along the width direction of the base 1. The slider 22 is slidably sleeved on the two slide bars so that the slider 22 can be limited by the two slide bars, so that the slider 22 can only slide along the length direction of the slide bars.

[0038] Furthermore, the massage mechanism also includes two boundary sensors 41 and a trigger 43. The two boundary sensors 41 are fixedly disposed on the outer side wall of the base 1 and distributed along the length direction of the guide structure 20. The trigger 43 is disposed on the slider 22. The trigger 43 can slide with the slider 22 to approach any one of the boundary sensors 41. When the trigger 43 is adjacent to the boundary sensor 41, it can trigger the boundary sensor 41.

[0039] Furthermore, the massage mechanism also includes a positioning sensor 42, which is fixedly mounted on the outer wall of the base 1 and located between two boundary sensors 41. The trigger 43 can slide close to the positioning sensor 42 with the slider 22. When the trigger 43 is adjacent to the positioning sensor 42, it can trigger the positioning sensor 42.

[0040] Furthermore, both the boundary sensing element 41 and the positioning sensing element 42 are Hall sensors, and the trigger element 43 is a magnet.

[0041] In this embodiment, when the slider 22 slides towards one end of the slide bar, causing the magnet to approach a boundary sensor 41, the boundary sensor 41 will be triggered. After the corresponding control board detects the signal from the boundary sensor 41, it will control the motor to reverse, causing the slider 22 to slide towards the other end of the slide bar. Similarly, when the magnet triggers another boundary sensor 41, the slider 22 will change its sliding direction again. This process repeats, thereby realizing the reciprocating movement of the massage head 7. At the same time, when the user turns off the massager, the slider 22 will slide along a predetermined route until the magnet approaches the positioning sensor 42. The magnet will then trigger the positioning sensor 42. After the corresponding control board detects the signal from the positioning sensor 42, it will turn off the motor, thereby realizing the power-off reset of the massage head 7.

[0042] In one embodiment, both the boundary sensor 41 and the positioning sensor 42 are mechanical switches, such as microswitches, and the trigger 43 is a protrusion disposed on the slider 22. The slider 22 can move to bring the protrusion closer and trigger the mechanical switch (not shown in the figure).

[0043] In one embodiment, both the boundary sensing element 41 and the positioning sensing element 42 are optical sensors, such as optocouplers. The trigger element 43 is a baffle disposed on the slider 22. Under normal conditions, the optocoupler is conducting. When the baffle moves with the slider 22 to between the transmitting end and the receiving end of the optocoupler, the transmitting end and the receiving end of the optocoupler will be isolated, thereby triggering the optocoupler (not shown in the figure).

[0044] Furthermore, the massage mechanism also includes a second massage device. The motor is centrally located on the base 1 and is positioned along the width of the base 1. The first massage device 2 is located at the left end of the base 1, and the second massage device is located at the right end of the base 1. The second massage device and the first massage device 2 are symmetrical about the axis of the motor. Two clearance openings 12 are symmetrically opened at both ends of the base 1. The clearance openings 12 are arranged in the same direction as the guide structure 20. In use, the motor will simultaneously drive the first massage device 2 and the second massage device to operate, so as to increase the massage points of the massage mechanism through the second massage device with the same structure, which is convenient to simulate the massage of both hands at the same time and improve the massage effect.

[0045] A massager includes a massage mechanism, an outer cover 5, two elastic fabrics 6, two sets of massage heads 7, and a pair of straps 8. The outer cover 5 is spliced ​​with a base 1 to form a cavity 11 for accommodating a first massage device 2, a second massage device, and a drive unit 3. The two elastic fabrics 6 are both disposed on the inner sidewall of the base 1 and cover the clearance openings 12. The rotating shaft 231 of the follower gear 23 extends toward the inner sidewall of the base 1, passes through the corresponding clearance opening 12, and passes through the corresponding elastic fabric 6 to the outside. The massage heads 7 are correspondingly disposed on the through end of the rotating shaft 231. Each massage head 7 includes a central rotating head and two rotating heads. The central rotating head is fixedly connected to the through end of the rotating shaft 231, and the two rotating heads are rotatably connected to both sides of the central rotating head. The straps 8 are respectively set at both ends of the base 1. When in use, the massager can be tied to the user's back through the straps 8. When the rotating shaft 231 moves synchronously with the slider 22 in the clearance opening 12, the follower gear 23 will drive the rotating shaft 231 to rotate synchronously, thereby driving the two massage heads 7 to move away from or closer to each other along the length direction of the base 1, while maintaining their own rotation. The rotating heads roll and squeeze the user's back muscles. The first massage device 2 and the second massage device with the same structure and movement mode drive the corresponding massage heads 7 to move and rotate, simulating the simultaneous pushing and pressing of the user's back muscles by both hands. During this process, the elastic cloth 6 will undergo adaptive deformation, always covering the clearance opening 12 to prevent external dust and debris from entering the receiving cavity 11.

[0046] Specifically, the cavity 11 also contains a built-in battery that can power the motor, the boundary sensor 41, the positioning sensor 42, and the corresponding control board.
