Description

Technical Field

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

[0002] In today's fast-paced world, people face increasing work and life pressures, leading to widespread physical fatigue and muscle soreness. Massage devices, with their ability to effectively relieve fatigue and promote blood circulation, are experiencing a continuous rise in market demand. As the core component of massage devices, the massage head mechanism's structural design and performance directly impact the massage effect and user experience.

[0003] Currently, most massage head mechanisms on the market use rotating massage heads. During rotation, different massage sections alternately massage the user. Typically, these sections are of similar shape and size, and the contact angle and pressure between them and the user's area remain relatively fixed during rotation. However, the contours and curves of different parts of the human body are complex and varied. For example, shoulder muscles are thick and irregularly shaped, the waist has a convex-convex physiological curve, and the neck is relatively slender and has a high degree of mobility. A fixed-structure massage head cannot closely conform to the complex contours of different parts of the body. During massage, it is easy for some areas to receive insufficient massage pressure while others receive excessive pressure. This not only fails to achieve the desired massage effect but may also cause discomfort or even injury to the user.

[0004] Furthermore, existing massage head mechanisms have significant shortcomings in meeting the personalized needs of different users. Different users have different body types, constitutions, and preferences for massage intensity and methods. Existing massage heads cannot flexibly adjust to the specific needs of each user, making it difficult to satisfy diverse massage requirements. Moreover, because the massage heads cannot adaptively conform to the body surface, problems such as jamming and friction can easily occur during the massage process, reducing the lifespan and operational stability of the massage device.

[0005] To address these issues, while some technologies have attempted to optimize massage effects by increasing the number of massage heads or adjusting their arrangement, these improvements only alleviate the problems to a certain extent and do not fundamentally solve the core challenge of massage heads failing to adaptively conform to the human body surface. Therefore, developing a massage head mechanism that can adaptively adjust to the contours of the user's massaged area, achieving a more precise, comfortable, and personalized massage experience, has become a crucial issue urgently needing to be addressed in the current massage equipment industry. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the technical defects of existing massage head mechanisms, such as the massage head not being able to adapt to the human body surface, poor massage effect, and difficulty in meeting personalized needs, and to provide a massage head mechanism that can adapt to the undulations of the part of the human body being massaged, so as to achieve a precise, comfortable and diversified massage experience.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An adaptive massage head mechanism includes a base, a drive unit, and a massage head. The drive unit is installed in the base, and a rotating shaft is provided at the output end of the drive unit. The massage head is mounted on the rotating shaft.

[0009] The massage head includes a mounting portion and a first massage portion and a second massage portion located on opposite sides of the mounting portion, wherein the height of the first massage portion is lower than that of the second massage portion.

[0010] The mounting part is adaptively hinged to the end of the rotating shaft so that the first massage part and the second massage part can rotate with the rotation of the rotating shaft, and can swing as the user's massaged area undulates.

[0011] The mounting part is adaptively hinged to the end of the rotating shaft so that the first massage part and the second massage part can rotate with the rotation of the rotating shaft, and can swing as the user's massaged area undulates.

[0012] Furthermore, a universal ball joint is installed at the end of the rotating shaft, and the mounting part of the massage head is hinged to the universal ball joint. A limiting structure is also provided between the massage head and the rotating shaft. The limiting structure is configured to restrict the massage head from swinging with the first massage part and the second massage part as the swing end.

[0013] Furthermore, the limiting structure includes a bearing seat disposed at the end of the rotating shaft, wherein one of the bearing seat and the mounting portion of the massage head has a groove, and the other has a protrusion that movably engages with the groove, and both the groove and the protrusion have arc-shaped cross sections.

[0014] Furthermore, the universal ball joint is fixed to the end of the rotating shaft by screws, the bearing seat is installed between the universal ball joint and the end of the rotating shaft, and the screw is tightened after passing through the universal ball joint, the bearing seat and the end face of the rotating shaft in sequence.

[0015] Furthermore, the bearing seat has a shaped groove, and the end of the rotating shaft has a non-circular structure that mates with the shaped groove, so that the end of the rotating shaft can be inserted into the shaped groove.

[0016] In another embodiment, a mounting base is sleeved at the end of the rotating shaft, the mounting base has a slot, a pin is inserted through the mounting part of the massage head, the pin is engaged in the slot, and the pin can rotate in the slot to make the massage head swing.

[0017] Furthermore, the massage head includes a first massage head and a second massage head arranged side by side, and the driving device has two output ends, with the first massage head and the second massage head respectively mounted on the rotating shafts corresponding to the two output ends.

[0018] Furthermore, the driving device includes a dual-axis motor, which has a first output end and a second output end. Each of the first output end and the second output end is equipped with a rotating shaft, and the first massage head and the second massage head are respectively mounted on the two rotating shafts.

[0019] Furthermore, the drive device includes a transmission mechanism disposed at the output end of the dual-axis motor. The output shaft of the dual-axis motor is a worm gear structure. The transmission mechanism includes a worm wheel that cooperates with the worm gear structure and a gear pair for speed reduction. The gear pair includes a first gear coaxially disposed with the worm wheel and a second gear that cooperates with the first gear. The rotating shaft is configured as the central shaft of the second gear.

[0020] Furthermore, the base includes a first housing and a second housing that can be fitted together, and the first housing and the second housing are fixed together by bolts.

[0021] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:

[0022] 1. The mounting part of the massage head of this utility model is adaptively hinged to the end of the rotating shaft. On the one hand, the first and second massage parts have different heights, which enhances the massage experience during switching. On the other hand, the first and second massage parts can adaptively swing according to the rise and fall of the user's massaged area. When the massage device is applied to the shoulder, the massage head can flexibly adjust its angle and position according to the thick and irregular shape of the shoulder, ensuring full contact between the massage part and the shoulder muscles. When massaging the waist, it can conform to the physiological curves of the waist, always maintaining a close fit and avoiding any suspension or excessive compression. This precise fit effectively avoids the problem of insufficient or excessive massage intensity in some areas, greatly improving the user's massage comfort and making the massage effect more significant, better relieving muscle fatigue and promoting blood circulation.

[0023] 2. The universal ball joint with limiting structure at the end of the rotating shaft of this utility model provides a reliable guarantee for the stable operation and precise massage of the massage head. In the limiting structure, the groove and protrusion between the shaft seat and the massage head mounting part are movable, and the cross-sections are all arc-shaped. This design ensures that the massage head can swing flexibly to adapt to the undulations of the human body surface, while limiting its swing range to prevent excessive swinging or random shaking. When the massage head massages the human body surface, even when encountering relatively complex contour changes, the limiting structure can keep the massage head within a reasonable swing range, ensuring the stability of the massage force and direction.

[0038] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0039] Example 1:

[0040] Please see Figures 1 to 4 The adaptive massage head mechanism 100 provided by this utility model mainly includes a base 110, a drive device 120, and a massage head 130. The drive device 120 is installed inside the base 110, and its output end is equipped with a rotating shaft 122. The massage head 130 is mounted on the rotating shaft 122 and is a key component that directly contacts the human body for massage.

[0041] In this embodiment, the massage head 130 includes a mounting portion 1303 and a first massage portion 1301 and a second massage portion 1302 located on opposite sides of the mounting portion 1303. The height of the first massage portion 1301 is lower than that of the second massage portion 1302. The mounting portion 1303 is adaptively hinged to the end of the rotating shaft 122 so that the first massage portion 1301 and the second massage portion 1302 can rotate with the rotation of the rotating shaft 122, and can swing as an oscillating end to oscillate with the rise and fall of the user's massaged area.

[0042] In some embodiments, the mounting portion 1303 is adaptively hinged to the end of the rotating shaft 122 by mounting a universal ball joint 123 to the end of the rotating shaft 122, and the mounting portion 1303 of the massage head 130 is hinged to the universal ball joint 123. During the massage process, when the massage device acts on the human shoulder, because the shoulder muscles are thick and irregularly shaped, the first massage portion 1301 and the second massage portion 1302 of the massage head 130 can flexibly adjust their angle and position according to the contour of the shoulder under the action of the universal ball joint 123, so that the massage portion can fully contact the shoulder muscles. As the rotating shaft 122 rotates, the first massage portion 1301 and the second massage portion 1302 alternately massage the shoulder. The massage portions with different heights provide the user with different massage strengths and sensations during the switching process, enhancing the massage experience. When massaging the lower back, the convex and concave physiological curves of the lower back cause the massage head 130 to be subjected to forces in different directions. At this time, the universal ball head 123 allows the massage head 130 to swing, so that it can conform to the curve of the lower back and always maintain a close fit, avoiding situations of being suspended or excessively squeezed. This effectively avoids the problem of insufficient or excessive massage intensity in some areas, greatly improving the user's massage comfort, while significantly enhancing the massage effect, and better realizing the functions of relieving muscle fatigue and promoting blood circulation.

[0043] To ensure the stability and controllability of the massage head 130's oscillation, a limiting structure 124 is provided between the massage head 130 and the rotating shaft 122. The limiting structure 124 includes a bearing 1241 located at the end of the rotating shaft 122. One bearing 1241 has a groove, and the other has a protrusion between it and the mounting portion 1303 of the massage head 130. In this embodiment, the mounting portion 1303 of the massage head 130 has a groove 1242, and the bearing 1241 has a protrusion 1243 that movably engages with the groove 1242. Both the groove 1242 and the protrusion 1243 have arc-shaped cross-sections. When the massage head 130 oscillates with the contours of the human body, the protrusion 1243 slides within the groove 1242. The arc-shaped design allows the massage head 130 to oscillate flexibly within a certain range while limiting its oscillation range, preventing excessive oscillation or random shaking of the massage head 130. When the massage head 130 encounters complex contours on the human body surface, such as the area near the spine on the back, the limiting structure 124 keeps the massage head 130 within a reasonable swing range, ensuring the stability of the massage force and direction, thereby achieving precise massage. Furthermore, stable operation reduces jamming and friction between the massage head 130 and the human body surface, lowers operating noise, extends the lifespan of the massage device, and improves overall operational stability and reliability.

[0044] In one embodiment, the universal ball joint 123 is fixed to the end of the rotating shaft 122 by screws 125, and the bearing seat 1241 is installed between the universal ball joint 123 and the end of the rotating shaft 122. The screws 125 are tightened after passing through the end faces of the universal ball joint 123, the bearing seat 1241, and the rotating shaft 122 in sequence. During installation, the bearing seat 1241 is first placed in the pre-set installation position at the end of the rotating shaft 122, and then the universal ball joint 123 is placed on the bearing seat 1241, aligning the screw holes on the universal ball joint 123, the bearing seat 1241, and the rotating shaft 122. Then, the screws 125 are passed through the screw holes of these components in sequence and tightened to ensure a stable connection between the components, prevent loosening during the operation of the massage head mechanism 100, and ensure the reliability of power transmission.

[0045] In addition, in one embodiment, the bearing seat 1241 has a shaped groove, and the end of the rotating shaft 122 has a shaped structure that mates with the shaped groove. During installation, the end of the rotating shaft 122 is inserted into the shaped groove, which further enhances the connection strength and stability between the rotating shaft 122 and the bearing seat 1241, making the rotating shaft 122 more stable and reliable when transmitting power.

[0046] In some embodiments, the massage head 130 includes a first massage head 131 and a second massage head 132 arranged side by side. The drive device 120 has two output ends, and the first massage head 131 and the second massage head 132 are respectively mounted on the rotating shafts corresponding to the two output ends. In this embodiment, the drive device 120 uses a dual-axis motor 121, which has a first output end and a second output end. Each of the first and second output ends is equipped with a rotating shaft 122, namely a first rotating shaft and a second rotating shaft. The first massage head 131 is mounted on the first rotating shaft corresponding to the first output end of the dual-axis motor 121, and the second massage head 132 is mounted on the second rotating shaft corresponding to the second output end. During actual massage, when the user uses the massage device to massage their back, the dual-axis motor 121 is activated, and the first and second rotating shafts drive the first massage head 131 and the second massage head 132 to rotate synchronously. During rotation, the first massage head 131 and the second massage head 132, with their respective first massage portions 1301 and 1302, not only utilize their height difference to provide users with diverse massage sensations, but also allow both massage heads to simultaneously cover a large area of ​​the back, significantly improving massage efficiency compared to a single massage head. For example, when massaging the muscles on both sides of the spine, the first massage head 131 can focus on massaging one side of the muscles, while the second massage head 132 massages the other side. Simultaneously, through an adaptive hinge structure and a limiting structure, the angle and position are flexibly adjusted according to the contours of the back, ensuring that both massage heads closely conform to the back skin and apply appropriate massage pressure to different areas of the muscles. This achieves a more comprehensive and precise massage, effectively relieving back muscle fatigue and enhancing the user's massage experience.

[0047] In some embodiments, the drive device 120 includes a transmission mechanism 126 disposed at the output end of the dual-axis motor 121. The output shaft 1211 of the dual-axis motor 121 is a worm gear structure, which works in conjunction with the transmission mechanism 126 disposed at the output end. The transmission mechanism 126 includes a worm wheel 1261 meshing with the worm gear structure and a gear pair for speed reduction. The gear pair consists of a first gear 1262 coaxially disposed with the worm wheel 1261 and a second gear 1263 meshing with the first gear 1262. The rotating shaft 122 is configured as the central shaft of the second gear 1263. When the dual-axis motor 121 is powered on and started, the worm gear structure of the output shaft 1211 drives the worm wheel 1261 to rotate. The worm wheel 1261 transmits power to the second gear 1263 through the coaxial first gear 1262. Due to the speed reduction effect of the gear transmission, the rotating shaft 122 rotates at a low speed and high torque suitable for massage work, thereby providing a stable and suitable power output to the massage head 130.

[0048] Furthermore, since the dual-axis motor 121, in conjunction with the transmission mechanism 126, can flexibly adjust the speed and torque of the rotating shaft 122 according to different massage needs, when using the dual massage heads, users can select appropriate massage modes based on their different physical conditions and massage preferences. For example, for users with stiff muscles, the motor speed and torque can be increased, allowing the massage heads to massage with greater force and faster speed, more effectively relaxing stiff muscles; while for users with sensitive skin, the motor speed and torque can be reduced, allowing the massage heads to massage with gentler force and slower speed, avoiding damage to the skin. This meets the diverse massage needs of different users, further enhancing the applicability and market competitiveness of the massage equipment.

[0049] In some embodiments, the base 110 includes a first housing 111 and a second housing 112 that can be fitted together and are fixed together by bolts. This split-structure design allows for the installation of the drive unit 120. First, the drive unit 120 is placed in a pre-set mounting slot in the first housing 111 or the second housing 112. Then, the other housing is closed, and bolts are passed through corresponding screw holes on the first housing 111 and the second housing 112 and tightened, thereby securely installing the drive unit 120 inside the base 110. Furthermore, this structure of the base 110 allows for easy opening of the base 110 during subsequent maintenance and repair, simply by unscrewing the bolts, to inspect, repair, or replace the drive unit 120. This convenient operation ensures the overall strength and stability of the base 110 and provides a reliable protective and support environment for the internal components of the movement.

[0050] Example 2:

[0051] This embodiment demonstrates another implementation of the hinged connection between the massage head 130 and the rotating shaft 122. In this embodiment, a mounting base is sleeved at the end of the rotating shaft 122, and the mounting base has a slot. A pin is inserted through the mounting portion 1303 of the massage head 130, and the pin is engaged in the slot, allowing the pin to rotate within the slot to make the massage head 130 swing. During installation, the mounting base is first fixed to the end of the rotating shaft 122 by interference fit or key connection, ensuring that the mounting base rotates synchronously with the rotating shaft 122. Then, the pin on the mounting portion 1303 of the massage head 130 is aligned with the slot on the mounting base and inserted, so that the pin is engaged within the slot. When the massage head 130 is subjected to a force generated by changes in the contour of the human body surface, the pin can rotate within the slot, thereby achieving adaptive swinging of the massage head 130. This hinged connection also allows the massage head 130 to swing flexibly with the undulations of the user's massaged area, ensuring good contact between the massage head 130 and the human body surface, providing the user with a comfortable massage experience. Meanwhile, the structure is relatively simple, easy to process, manufacture and assemble, reducing production costs, and while ensuring the 130-degree swing performance of the massage head, it has good stability and reliability.
