Description

Technical Field

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

[0002] Currently, most neck and shoulder massagers on the market use traditional gear transmissions or single eccentric wheel structures, which suffer from low transmission efficiency, limited movement modes, and uneven massage intensity. For example, while a basic transmission structure enables the massage head to oscillate, the transmission system relies on multi-stage gear sets, resulting in a complex structure, significant noise, and a limited massage trajectory, making it difficult to simulate the kneading techniques of human hands. Furthermore, the insufficient freedom of movement of the massage head in existing technologies leads to a narrow massage range, failing to effectively conform to the curves of the human body, and is prone to mechanical wear and tear with long-term use, affecting its lifespan.

[0003] Therefore, we propose a neck and shoulder massager mechanism to address the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a neck and shoulder massager mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a neck and shoulder massager mechanism, comprising: a housing, inside which are arranged a motor, a transmission box, an inner housing, a limiting component, and a transmission shaft, wherein the motor drives and connects to the transmission box, the transmission box is fixedly connected to the inner housing, and the transmission box drives and connects to a first massage head and a second massage head;

[0006] An eccentric wheel and an inclined wheel are rotatably arranged inside the inner shell. The eccentric wheel and the inclined wheel are integrally formed, and the eccentric wheel is fixedly connected to the drive shaft.

[0007] The second massage head includes a first swing arm, one end of which is annular and sleeved on an eccentric rotating wheel. The other end of the first swing arm is hinged to a second swing arm via a hinge shaft. The upper end of the second swing arm is integrally connected to a massage ball. A limiting member is slidably connected to the middle of the second swing arm. The limiting member is fixedly set and has a straight through hole in the middle. The straight through hole slidably connects to the second swing arm. A limiting pin moves through the limiting member and moves through the second swing arm. The limiting pin is perpendicular to the straight through hole.

[0008] Preferably, a double gear and a driven gear are rotatably arranged inside the transmission box, and the output end of the motor is a worm gear.

[0009] Preferably, the double gear is integrally stacked with a worm gear and a gear on the same axis, wherein the worm gear is connected to the worm drive of the motor.

[0010] Preferably, the gear meshes with the driven gear, the driven gear is coaxially and fixedly connected to the transmission shaft, and the transmission shaft is rotatably disposed within the inner housing.

[0011] Preferably, the first massage head is integrally connected to the connecting rod, and the lower end of the connecting rod is integrally connected to the hemispherical joint. The plane of the hemispherical joint fits with the inclined surface of the inclined wheel. The inner shell is provided with hemispherical grooves at both ends, and the hemispherical joint is movably disposed in the hemispherical groove.

[0012] Preferably, the housing has a second hole and a first hole for the movement of the connecting rod and the second swing arm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The transmission method of worm gear and double gear (worm wheel-gear coaxial stacked structure) simplifies the traditional multi-stage gear structure, reduces energy loss and meshing noise, and improves the stability of power output.

[0015] 2. Through the integrated design of the eccentric rotating wheel and the inclined wheel, combined with the oscillation driven by the inclined wheel of the first massage head and the linkage of the eccentric limiting arm of the second massage head, a compound motion of kneading and tapping is achieved, simulating real human techniques and significantly improving massage comfort.

[0016] 3. The design of the limiting component in the second massage head, along with the straight through hole and the limiting pin, constrains the sliding trajectory of the second swing arm, prevents movement deviation, ensures the directional reciprocating swing of the massage ball, and enhances the uniformity of massage intensity.

[0017] 4. The integrated layout of the inner shell and transmission box, combined with the hinge design of the hemispherical joint and hemispherical groove, reduces the frictional wear of parts, extends the service life of the mechanism, and at the same time reduces the overall size, making it easier to adapt to different massager shells.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a neck and shoulder massager core, including: a housing 1, inside which a motor 9, a transmission box 4, an inner housing 5, a limiting member 6 and a transmission shaft 7 are arranged; the motor 9 drives and connects to the transmission box 4; the transmission box 4 is fixedly connected to the inner housing 5; the transmission box 4 drives and connects to the first massage head 2 and the second massage head 3.

[0026] A double gear 41 and a driven gear 42 are rotatably arranged inside the transmission box 4. The output end of the motor 9 is a worm. The double gear 41 is formed by the coaxial integral stacking of the worm wheel and the gear. The worm wheel is connected to the worm of the motor 9 for transmission, and the gear meshes with the driven gear 42. The driven gear 42 is coaxially fixedly connected to the transmission shaft 7, and the transmission shaft 7 is rotatably arranged inside the inner housing 5.

[0027] An eccentric wheel 8 and a sloping wheel 10 are rotatably arranged inside the inner housing 5. The eccentric wheel 8 and the sloping wheel 10 are integrally formed. The eccentric wheel 8 is fixedly connected to the transmission shaft 7. Power is output through the motor 9, and then the transmission shaft 7 is driven to rotate through the double gear 41 and the driven gear 42, which in turn drives the eccentric wheel 8 and the sloping wheel 10 to rotate.

[0028] The first massage head 2 is integrally connected to the connecting rod 21. The lower end of the connecting rod 21 is integrally connected to the hemispherical joint 22. The plane of the hemispherical joint 22 fits against the inclined surface of the inclined wheel 10. The inner shell 5 is provided with hemispherical grooves 51 at both ends. The hemispherical joint 22 is movably disposed in the hemispherical grooves 51.

[0029] The rotation of the inclined wheel 10 compresses the hemispherical joint 22 to move within the hemispherical groove 51, thereby causing the connecting rod 21 to drive the first massage head 2 to swing, thus achieving a massage on the human body.

[0030] The second massage head 3 includes a first swing arm 32. One end of the first swing arm 32 is annular and is sleeved on the eccentric rotating wheel 8. The other end of the first swing arm 32 is hinged to the second swing arm 33 through the hinge shaft 34. The upper end of the second swing arm 33 is integrally connected to the massage ball 31. The middle part of the second swing arm 33 is slidably connected to the limiting member 6. The limiting member 6 is fixedly set. A straight through hole 61 is opened in the middle of the limiting member 6. The straight through hole 61 is slidably connected to the second swing arm 33. A limiting pin 62 is movable through the limiting member 6. The limiting pin 62 is movable through the second swing arm 33, and the limiting pin 62 is perpendicular to the straight through hole 61.

[0031] Because the eccentric wheel 8 is eccentrically positioned relative to the drive shaft 7, the eccentric wheel 8 will move in a circular motion around the drive shaft 7, thereby driving one end of the first swing arm 32 to move back and forth in a circular motion, pulling the lower end of the first swing arm 32 to move back and forth. Through the lever principle of the limiting pin 62 and the limiting of the straight through hole 61, the first swing arm 32 swings back and forth around the limiting pin 62, driving the massage ball 31 to massage the human body.

[0032] The housing 1 has a connecting rod 21 and a second hole 11 and a first hole 12 for the movement of the second swing arm 33.

[0033] Working principle: The motor 9 drives the transmission box 4, which in turn drives the transmission shaft 7 to rotate. The transmission shaft 7 drives the eccentric wheel 8 to rotate eccentrically, which in turn drives the inclined wheel 10 to rotate. The eccentric wheel 8 pulls the second swing arm 33 to swing back and forth through the first swing arm 32. The inclined wheel 10 squeezes the hemispherical joint 22, which drives the connecting rod 21 to swing, thereby realizing the movement of the first massage head 2 and the second massage head 3 to massage the human body.
