Description

Technical Field

[0001] This utility model relates to the technical field of massage devices, and particularly to a shoulder and neck massager.

Background Art

[0002] In modern fast-paced life rhythms, people use electronic devices such as computers and mobile phones while maintaining a certain posture for a long time, or engage in long hours of desk work or study. As a result, the shoulders and neck are constantly in a tense state, and problems such as muscle stiffness, pain, and fatigue in the shoulders and neck are becoming increasingly prevalent. As a common device to relieve such problems, shoulder and neck massagers have always attracted consumers' attention. However, currently marketed shoulder and neck massagers generally have functional limitations, and can only provide a single method such as kneading and loosening the shoulders and neck or acupressure massage, and often cannot simultaneously meet the user's demand for back massage. In addition, the design of the transmission structure adopted by some massagers is unreasonable, and there are problems such as a decrease in transmission efficiency, significant vibration during operation, and high noise, which not only have an adverse impact on the massage experience but also shorten the lifespan of the device.

[0014] The drawings and embodiments will be used to further describe this utility model. However, the embodiments described below are for illustrative purposes only and do not limit the scope of this utility model. Similarly, the embodiments described below are only a subset of the embodiments of this utility model, and all other embodiments that a person skilled in the art could obtain without creative effort are included within the scope of protection of this utility model.

[0015] Refer to Figures 1 to 7. In this embodiment, the shoulder and neck massager includes a drive motor 1, a transmission mechanism, a back tapping section 4, and a shoulder and neck massage section 5, wherein a drive worm 11 is fixedly connected to the output terminal of the drive motor 1, a drive wheel 12 is positioned at the end of the drive worm 11 closest to the drive motor 1, the drive motor 1 supplies power, the transmission mechanism is transmitted to the drive motor 1, the transmission mechanism includes a first transmission assembly and a second transmission assembly, the first transmission assembly includes a first rotating shaft 21, a first transmission rod 22, and a first eccentric wheel 23, there are two first eccentric wheels 23, and the two first eccentric wheels 23 are each at both ends of the first rotating shaft 21 The first transmission rod 22 is connected to the drive worm 11 and the first rotating shaft 21, respectively, the second transmission assembly includes a second rotating shaft 31 and a transmission belt 32, a driven wheel 311 is positioned on the second rotating shaft 31, the driven wheel 311 is connected to the drive wheel 12 via the transmission belt 32, there are two back tapping sections 4, each of the two back tapping sections 4 is connected to two of the first eccentric wheels 23, and each of the back tapping sections 4 is connected to one of the second rotating shafts 31, there are two shoulder and neck massage sections 5, each of the two shoulder and neck massage sections 5 is connected to two of the first eccentric wheels 23.

[0016] As the core power component of this shoulder and neck massager, the drive motor 1 employs a DC brushless motor characterized by its small size, high power density, excellent speed control performance, and long lifespan. The drive worm 11 is manufactured from high-strength alloy steel, with one end having a helical structure and the other end fixed to the output terminal of the drive motor 1 by a key coupling. Both the drive wheel 12 and the driven wheel 311 are pulley structures; the drive wheel 12 is externally fitted and fixed to the end of the drive worm 11 closest to the drive motor 1, and the driven wheel 311 is externally fitted and fixed to the second rotating shaft 31. The drive wheel 12 and the driven wheel 311 are connected via a transmission belt 32, thereby distributing the power of the drive motor 1 to the second rotating shaft 31. The first transmission assembly drives the first eccentric wheel 23 by transmitting the power of the drive motor 1 to the first rotating shaft 21. The second transmission assembly transmits power from the drive motor 1 to the second rotating shaft 31 and, in cooperation with the first transmission assembly, supplies power to the back striking section 4. Specifically, when the drive motor 1 is energized and started, the motor rotor begins to rotate at high speed due to electromagnetic force, causing the drive worm 11 to rotate synchronously via the output shaft. The helical teeth of the drive worm 11 mesh with the drive worm wheel 221 located at one end of the first transmission rod 22. Because the transmission between the worm wheel and the worm has a large reduction ratio, the drive worm wheel 221 is pulled by the drive worm 11 and rotates at a low speed, thereby rotating the first transmission rod 22. The transmission worm 222 at the other end of the first transmission rod 22 meshes again with the first worm wheel 211 on the first rotating shaft 21 via a gear, transmitting power to the first rotating shaft 21 and causing the first rotating shaft 21 to rotate at a predetermined rotational speed. At this time, the first eccentric wheels 23 attached to both ends of the first rotating shaft 21 rotate in conjunction. Because the center of gravity of the first eccentric wheel 23 is offset from the center of rotation, centrifugal force is generated during rotation, causing the back tapping section 4 and shoulder / neck massage section 5 connected to it to move in a regular motion, thereby realizing a shoulder / neck massage function for the user. Specifically, the drive motor 1 drives the first rotating shaft 21, and the first eccentric wheels 23, which are positioned at both ends of the first rotating shaft 21, rotate synchronously. Because the first eccentric wheel 23 has directional eccentricity, the distance from each point on its edge to the center of rotation changes during rotation, so the shoulder / neck massage section 5 connected to it is driven.When the eccentric part of the first eccentric wheel 23 rotates toward the shoulder and neck area, the shoulder and neck massage part 5 moves inward. When the eccentric part rotates toward the shoulder and neck area, the shoulder and neck massage part 5 moves outward. This process is repeated to create a pinching and kneading motion on the shoulder and neck area, simulating the kneading motion used in manual massage and improving the massage effect.

[0017] At the same time, the drive wheel 12 of the drive worm 11 is transmitted to the driven wheel 311 of the second rotating shaft 31 via the transmission belt 32. When the drive wheel 12 rotates, power is transmitted to the driven wheel 311 by the frictional force between the transmission belt 32 and the pulley, causing the second rotating shaft 31 to rotate. The second rotating shaft 31 is connected to the back tapping section 4 via the second eccentric wheel 24 and the second transmission component 25. When the second eccentric wheel 24 rotates, it generates an additional oscillating motion in the back tapping section 4. As a result, the combined action of the first eccentric wheel 23 and the second rotating shaft 31 enables a stronger tapping motion by the back tapping section 4, further improving the tapping effect of the back tapping section 4. Meanwhile, the shoulder and neck massage section 5 continuously massages the shoulders and neck through the drive of the first eccentric wheel 23.

[0018] In this embodiment, the functions of shoulder and neck massage and back tapping are integrated into a shoulder and neck massager, allowing the user to enjoy shoulder, neck, and back massages simultaneously without using multiple massagers. This fully satisfies the user's diverse massage needs, effectively alleviating fatigue and pain in the shoulders, neck, and back, and improving the user's overall massage experience. By adopting a transmission system in which various transmission components such as the drive motor 1, drive worm 11, first transmission rod 22, first rotating shaft 21, and pulley cooperate with each other, it is ensured that power is transmitted stably and efficiently to the first eccentric wheel 23 and the second eccentric wheel 24. The transmission structure combining a worm wheel and worm not only operates smoothly and reduces vibration and noise of the equipment due to transmission instability, but also improves transmission efficiency, reduces energy loss, and extends the lifespan of the massager.

[0019] Refer to FIGS. 1, FIG. 2 and FIG. 6. In this embodiment, a driving worm wheel 221 and a transmission worm 222 are respectively arranged at both ends of the first transmission rod 22. The driving worm wheel 221 meshes with the driving worm 11. A first worm wheel 211 is arranged on the first rotating shaft 21. The first worm wheel 211 meshes with the transmission worm 222. Through holes are respectively provided in the first transmission rod 22, the driving worm wheel 221 and the transmission worm 222. The driving worm wheel 221 is externally fitted and fixed to one end of the first transmission rod 22. At this time, the rotating shafts of the through hole of the driving worm wheel 221 and the through hole of the first transmission rod 22 coincide. By passing a bolt through the through holes of both, the driving worm wheel 221 and the first transmission rod 22 are screwed together. The transmission worm 222 is externally fitted and fixed to the other end of the first transmission rod 22 and is similarly fixed to the first transmission rod 22 by screwing. The tooth profile of the driving worm wheel is compatible with the spiral teeth of the driving worm 11. When the driving worm wheel 221 and the driving worm 11 mesh, the rotational force of the driving worm 11 is transmitted to the first transmission rod 22. When the first transmission rod 22 rotates, the transmission worm 222 also rotates in conjunction. The transmission worm 222 meshes with the first worm wheel 211, whereby the power of the driving motor 1 is stably transmitted to the first rotating shaft 21. The transmission method of combining a worm wheel and a worm has high transmission efficiency and little energy loss during power transmission. Compared with other transmission methods, the transmission of combining a worm wheel and a worm can transmit the power of the driving motor 1 to the first rotating shaft 21 more efficiently, improve the energy utilization efficiency and reduce the waste of electric power. Also, during the meshing process of the worm wheel and the worm, the operation is smooth, and the noise caused by the vibration of the transmission parts can be effectively reduced. Since the wear between the parts is small and the operating stability is high, the long-term stable operation of the massager can be guaranteed, improving the user experience.

[0020] In this embodiment, the first rotating shaft 21 and the first worm wheel 211 are each provided with a first through hole, and the first rotating shaft 21 and the first worm wheel 211 are screwed together by passing a bolt through the first through hole. The first rotating shaft 21 is made of high-strength alloy steel, so it has high strength and rigidity and can withstand the centrifugal force and torque generated during the operation of the first eccentric wheel 23. There is a certain fitting tolerance between the inner bore of the first worm wheel 211 and the outer diameter of the first rotating shaft 21, and the first worm wheel 211 is externally fitted and fixed to the first rotating shaft 21. The first through hole is a circular through hole formed in the first rotating shaft 21 and the first worm wheel 211. The first through hole provides a passage for bolt installation, and the first worm wheel 211 and the first rotating shaft 21 are screwed together by passing a bolt through the first through hole, thereby fixing them together. Specifically, in assembling the massager, first the inner bore of the first worm wheel 211 is aligned with the first rotating shaft 21, and the first worm wheel 211 is temporarily fitted to the first rotating shaft 21 to confirm that the first through holes of both are perfectly aligned. Next, a bolt of the appropriate standard is selected, and the bolt is sequentially passed through the first through holes of the first worm wheel 211 and the first rotating shaft 21, and the bolt is tightened with a nut, or by machining a female thread on the first rotating shaft 21, thereby tightly fixing the first worm wheel 211 and the first rotating shaft 21 in a screw-type connection. When the massager is in operation, the first transmission rod 22 transmits power to the first worm wheel 211 via the transmission worm 222, and because the first worm wheel 211 and the first rotating shaft 21 are firmly connected by bolts, the rotation of the first worm wheel 211 rotates the first rotating shaft 21 synchronously, thereby transmitting power to the first eccentric wheels 23 attached to both ends of the first rotating shaft 21. During equipment maintenance or parts replacement, the first worm wheel 211 and the first rotating shaft 21 can be separated simply by loosening the bolts with the appropriate tool, allowing for quick and easy inspection, repair, or replacement of the first worm wheel 211 and the first rotating shaft 21.

[0021] Refer to Figures 3, 4, and 6. In this embodiment, the first eccentric wheel 23 has a first mounting groove 231 and a second mounting groove 232, the back striking section 4 has a first mounting section, and the shoulder and neck massage section 5 has a second mounting section, the first mounting section being housed in the first mounting groove 231 and the second mounting section being housed in the second mounting groove 232. The first eccentric wheel 23 is set to an eccentric structure, that is, the geometric center and the rotation center of the wheel itself do not coincide. The first eccentric wheel 23 is provided with a first mounting groove 231 and a second mounting groove 232, which are annular grooves having a specific shape and are used to attach the back striking section 4 and the shoulder and neck massage section 5, and their dimensions and shape are suited to the first mounting section of the back striking section 4 and the second mounting section of the shoulder and neck massage section 5. The first mounting section is a single annular hollow structure on the back striking section 4, and the back striking section 4 is externally fitted and fixed to the first mounting groove 231 by the first mounting section. The second mounting section is a single annular hollow structure located on the shoulder and neck massage section 5, and the shoulder and neck massage section 5 is externally fitted and fixed into the second mounting groove 232 by the second mounting section. Specifically, when the first rotating shaft 21 begins to rotate due to the drive of the first transmission assembly, the first eccentric wheels 23 attached to both ends of the first rotating shaft 21 rotate in conjunction. Due to the eccentric structure of the first eccentric wheels 23, a centrifugal force that changes periodically during rotation is generated. This centrifugal force acts on the back tapping section 4 attached to the first mounting groove 231 and the shoulder and neck massage section 5 attached to the second mounting groove 232, causing reciprocating motion in the back tapping section 4 and the shoulder and neck massage section 5, simulating the techniques of manual kneading and acupressure, and performing massage and tapping on the shoulder and neck area. On the other hand, the connection method using the combination of mounting grooves and mounting sections limits the degrees of freedom of movement of the back tapping section 4 and the shoulder and neck massage section 5, so that they operate along a predetermined motion trajectory, thereby ensuring the accuracy and stability of the massage motion.

[0022] Refer to FIGS. 1 and 5. In this embodiment, the back beating part 4 has a receiving groove, and the second transmission assembly further includes a second transmission component 25 and a second eccentric wheel 24. The second eccentric wheel 24 is in transmission connection with the second transmission component 25. The second eccentric wheel 24 has a cavity, one end of the second rotating shaft 31 is accommodated in the cavity, and the transmission part 251 of the second transmission component is accommodated in the receiving groove. There are two second transmission components 25 and two second eccentric wheels 24 respectively. The two second eccentric wheels 24 are respectively connected to both ends of the second rotating shaft 31. The receiving groove of the back beating part 4 is a concave groove with a specific shape, which accommodates the transmission part 251 of the second transmission component. Its dimensions and shape are adapted to the transmission part 251 of the second transmission component, ensuring that effective power transmission is realized between the two. The second eccentric wheel 24 has an eccentric structure, and the shape of the cavity inside it is consistent with the shape of one end of the second rotating shaft 31. One end of the second rotating shaft 31 is accommodated in the cavity of the second eccentric wheel 24 to realize an interference fit state. Specifically, the rotation of the second rotating shaft 31 drives the second eccentric wheel 24, and the centrifugal force generated by the eccentric structure of the second eccentric wheel 24 acts on the second transmission part 25, causing a reciprocating motion of the second transmission part 25. The torque is transmitted to the back beating part 4 through the transmission part 251 of the second transmission part. By the reciprocating motion of the back beating part 4, the beating effect on the user's back is realized.

[0023] In this embodiment, the second rotating shaft 31 and the second eccentric wheel 24 are each provided with a second through hole, and the second rotating shaft 31 and the second eccentric wheel 24 are screwed together by passing a bolt through the second through hole. The second rotating shaft 31 is made of high-strength stainless steel, has high strength and rigidity, and prevents deformation during the power transmission process. The second through hole is a circular through hole formed in the second rotating shaft 31 and the second eccentric wheel 24. The second through hole provides a passage for bolt installation, and the second eccentric wheel 24 and the second rotating shaft 31 are screwed together by passing a bolt through the second through hole, thereby fixing them together. Specifically, in the assembly process of the massager, first one end of the second rotating shaft 31 is inserted into the cavity of the second eccentric wheel 24 to temporarily position the two. After adjusting the position and confirming that the second through-hole of the second rotating shaft 31 and the second eccentric wheel 24 are perfectly aligned, a bolt of the appropriate standard is selected, and the bolt is passed through the second eccentric wheel 24 and the second through-hole of the second rotating shaft 31 in sequence, and a nut is tightened on the other side, or the bolt is tightened directly by machining an internal thread on the second rotating shaft 31, thereby securely fixing the second eccentric wheel 24 to the second rotating shaft 31.

[0024] When the second rotating shaft 31 begins to rotate due to the drive of the transmission belt 32, the second eccentric wheel 24 rotates in sync with the second rotating shaft 31 due to the tightening of the bolts. Due to the eccentric structure of the second eccentric wheel 24, centrifugal force is generated during rotation, which drives the second transmission component 25 connected to it, and ultimately the power is transmitted to the back striking section 4. When performing maintenance on the equipment or replacing parts, the second eccentric wheel 24 can be removed from the second rotating shaft 31 simply by loosening the bolts, making it easy to inspect, repair, or replace the second eccentric wheel 24 and the second rotating shaft 31.

[0025] Refer to Figure 7. In this embodiment, a housing 7 is further included, and both the drive motor 1 and the transmission mechanism are located within the space of the housing 7. The housing 7 is made of high-strength engineering plastic material and has excellent strength, toughness, and impact resistance. Specifically, in the process of assembling the massager, the drive motor 1 and the transmission mechanism are first installed in corresponding spaces inside the housing 7. The drive motor 1 is fixed in place in the housing 7 with a fixing holder or bolts to ensure that no shaking occurs during operation. In addition, the housing 7 provides appropriate support and positioning for the transmission components, preventing displacement during operation.

[0026] Refer to Figures 2 and 7. In this embodiment, an energy supply unit 8 is further included, which is located within a cavity in the housing 7 and is electrically connected to the drive motor 1. The energy supply unit 8 is a rechargeable lithium battery, which has advantages such as high energy density, low self-discharge rate, and long cycle life, and can provide a stable power supply to the drive motor 1.
