Description

Technical Field

[0001] This utility model relates to a massage device, specifically a shoulder and neck massager, and belongs to the field of massage device technology. Background Technology

[0002] A neck and shoulder massager is an electronic device designed to relieve fatigue, tension, and discomfort in the neck and shoulder area. It simulates various hand massage techniques, such as kneading, pushing, tapping, and vibration, to act on the muscles and acupoints in the neck and shoulder area to promote blood circulation, relax muscles, and reduce soreness. This helps improve neck and shoulder stiffness and pain, enhancing user comfort and quality of life. It is especially suitable for people who work at a desk for long periods, sit for long periods, or have heavy neck and shoulder burdens.

[0003] The core operating principle of a neck and shoulder massager typically relies on a drive motor to provide power, which in turn drives the massage components. However, a significant problem with existing technologies is that these massage mechanisms are often quite large in size. This not only affects the portability of the massager but may also limit its application scenarios to some extent. More importantly, to achieve precise driving and massage of multiple different parts of the neck and shoulder, existing massage mechanisms often require multiple drive motors. While this design meets massage needs to some extent, it also makes the structure more complex and redundant. The configuration of multiple drive motors not only increases the manufacturing cost of the massager but also further exacerbates the size problem of the overall structure. Therefore, a neck and shoulder massager device is proposed. Utility Model Content

[0004] In view of this, the present invention provides a massage device for a shoulder and neck massager to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

Detailed Implementation

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figures 1-4 As shown, this utility model embodiment provides a neck and shoulder massager, including a gearbox lower cover 31, and a drive assembly 101 is provided inside the gearbox lower cover 31;

[0030] The drive assembly 101 includes a dual-head drive motor 11, a trapezius muscle massage rocker arm 13, an output gear 16, an inclined wheel 17, a cervical column massage rocker arm 19, a push rod 20, a connecting pin 22, a drive gear 24, a drive worm gear 25, a connecting rod 27, and an eccentric wheel 28.

[0031] Both ends of the output shaft of the dual-head drive motor 11 are fixedly connected to motor worm gears 12. The drive worm wheel 25 is fixedly connected to the outer wall of the gear shaft of the drive gear 24. The outer wall of the motor worm gear 12 is meshed with the outer wall of the drive worm wheel 25. The outer wall of the output gear 16 is meshed with the outer wall of the drive gear 24. The dual-head drive motor 11 drives the motor worm gear 12 to rotate. When the motor worm gear 12 rotates, it drives the drive worm wheel 25 to rotate. The drive worm wheel 25 drives the drive gear 24 to rotate. The drive gear 24 drives the output gear 16 to rotate through its teeth.

[0032] The eccentric wheel 28 is fixedly connected to the outer wall of the gear shaft of the output gear 16, and the connecting rod 27 is rotatably connected to the outer wall of the eccentric wheel 28. Thus, when the output gear 16 rotates, the eccentric wheel 28 rotates accordingly. Since the connecting rod 27 is sleeved on the outside of the eccentric wheel 28 and rotatably connected to the eccentric wheel 28, the connecting rod 27 can reciprocate linearly when the eccentric wheel 28 rotates.

[0033] One end of the push rod 20 is rotatably connected to the trapezius massage rocker arm 13 via a connecting pin 22, and the other end of the push rod 20 is engaged with the connecting rod 27. The trapezius massage rocker arm 13 has a sliding groove 14 inside, and the connecting pin 22 is slidably connected inside the sliding groove 14. The bottom end of the trapezius massage rocker arm 13 is rotatably connected to the outer wall of the gear cover 26. When the connecting rod 27 moves back and forth, it drives the push rod 20, and the push rod 20 drives the connecting pin 22. The connecting pin 22 slides in the sliding groove 14, and at the same time, the connecting pin 22 drives the trapezius massage rocker arm 13, which in turn can make the trapezius massage rocker arm 13 swing back and forth, thereby realizing the massage of the trapezius muscle.

[0034] The inclined wheel 17 is fixedly connected to the outer wall of the gear shaft of the output gear 16. The neck massage rocker arm 19 is sleeved on the top of the inclined wheel 17. When the output gear 16 rotates, its gear shaft drives the inclined wheel 17 to rotate. When the inclined surface of the inclined wheel 17 rotates around the axis of the gear shaft, it can reciprocate to push the bottom of the neck massage rocker arm 19. The neck massage rocker arm 19 swings back and forth, thereby achieving massage of the neck.

[0035] In one embodiment, a fixing cover 18 is installed on the top of the inclined wheel 17, and the neck massage rocker arm 19 is limited to the top of the inclined wheel 17 by the fixing cover 18. The fixing cover 18 can limit the position of the neck massage rocker arm 19 and prevent the neck massage rocker arm 19 from falling off the top of the inclined wheel 17.

[0036] The top of the inclined wheel 17 is provided with a limit post, which, in conjunction with the fixed cover 18, can limit the position of the neck massage rocker arm 19.

[0037] In one embodiment, a gearbox upper cover 34 is mounted on the upper surface of the gearbox lower cover 31, and a gear cover 26 is symmetrically mounted on the lower surface of the gearbox lower cover 31. The gear shaft of the output gear 16 is rotatably connected to the interior of the gearbox lower cover 31 and the gearbox upper cover 34, thereby limiting the position of the output gear 16 and the neck massage rocker arm 19 to enhance the stability of the structure.

[0038] The gear shafts of the drive gear 24 are rotatably connected to the inside of the gear cover 26. The dual-head drive motor 11 is installed inside the gearbox lower cover 31. The dual-head drive motor 11 is existing technology, so its internal structure, working principle and control method will not be described in detail.

[0039] In one embodiment, a main cover plate 32 is installed on the upper surface of the gearbox cover 34. A limiting groove 33 is formed inside the main cover plate 32. The top of the neck massage rocker arm 19 is slidably connected to the inside of the limiting groove 33. The position of the neck massage rocker arm 19 can be limited by the limiting groove 33. When the bottom of the neck massage rocker arm 19 is pushed by the inclined wheel 17, its top can slide in the limiting groove 33, thereby realizing the massage action.

[0040] Example 2

[0041] like Figure 5 As shown, the trapezius massage rocker arm 13 has a groove 41 inside. The end of the push rod 20 is fixedly connected to a ball head 42. The ball head 42 is slidably connected to the inner wall of the groove 41. When the push rod 20 moves with the connection 27, the push rod 20 pushes the ball head 42, and the ball head 42 drives the trapezius massage rocker arm 13 to swing. At the same time, the ball head 42 can slide inside the groove 41.

[0042] When this utility model is in operation: the dual-head drive motor 11 drives the motor worm 12 to rotate, the motor worm 12 drives the drive worm wheel 25 to rotate, the drive worm wheel 25 drives the drive gear 24 to rotate, the drive gear 24 drives the output gear 16 to rotate through the teeth, and when the output gear 16 rotates, the eccentric wheel 28 rotates accordingly. Since the connecting rod 27 is sleeved on the outside of the eccentric wheel 28 and rotates in connection with the eccentric wheel 28, the connecting rod 27 can reciprocate linearly when the eccentric wheel 28 rotates. When the connecting rod 27 reciprocates, it drives the push rod 20, the push rod 20 drives the connecting pin 22, the connecting pin 22 slides in the slide groove 14, and at the same time the connecting pin 22 drives the trapezius muscle massage rocker arm 13, which in turn can make the trapezius muscle massage rocker arm 13 swing back and forth, thereby realizing the massage of the trapezius muscle.

[0043] Meanwhile, during the rotation of the output gear 16, its gear shaft drives the inclined wheel 17 to rotate. When the inclined surface of the inclined wheel 17 rotates around the axis of the gear shaft, it can reciprocate to push the bottom of the neck massage rocker arm 19. The top of the neck massage rocker arm 19 slides in the limiting groove 33, thereby causing the neck massage rocker arm 19 to swing back and forth, thus achieving massage of the neck.

[0044] Compared with the prior art, this utility model uses a drive component 101 to drive the trapezius muscle massage rocker arm 13 and the cervical column massage rocker arm 19 with a single motor, which simplifies the structure, makes the overall structure more compact and portable, and reduces the production cost of the massager.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
