Description

Technical Field

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

[0002] The massage mechanism is an important component of a massager. Its main function is to simulate the massage of the back by human hands, thereby relieving fatigue, relaxing tense muscles, and promoting blood circulation. The massage function, massage techniques, and massage experience it provides to the user are very important in massage equipment.

[0003] The above-mentioned technical conditions still have some defects: the existing neck massage device mechanisms mostly adopt a single-stage gear transmission structure, which has poor transmission stability and the motor vibration is prone to generating noise. Traditional mechanisms have defects such as insufficient massage intensity, high operating noise and complex component assembly.

[0004] Based on this, the present invention designs a neck massage mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a neck massage mechanism to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a neck massage mechanism, comprising a lower cover and an upper cover. A mounting base is provided on the lower cover, and a drive motor is mounted on the mounting base. A worm gear is fixedly connected to the output shaft of the drive motor. Two sets of double gears meshing with the worm gear are rotatably connected to the lower cover. Two sets of secondary transmission gears meshing with the double gears are also rotatably connected to the lower cover. Kneading gears are rotatably connected to both sides of the lower cover. An eccentric block is engaged with the kneading gear. A massage head rocker arm is connected to the top of the eccentric block. A limiting sleeve is connected to the upper cover, and the limiting sleeve is fitted over the massage head rocker arm and the eccentric block.

[0007] By adopting the above technical solution, the drive motor drives the double gear and the secondary transmission gear through a worm gear to perform multi-stage meshing transmission, which in turn drives the kneading gear to rotate at a constant speed, so that the eccentric block drives the massage head rocker arm to make periodic movements, thereby realizing the regular kneading of the neck tissue.

[0008] Preferably, the double gear and the secondary transmission gear are coaxially provided with upper and lower parts, wherein the upper parts of the two sets of double gears mesh with the worm gear, the lower parts of the two sets of secondary transmission gears mesh with the lower parts of the two sets of double gears respectively, and the upper part of the secondary transmission gear meshes with the kneading gear.

[0009] By adopting the above technical solutions, multi-stage transmission significantly improves torque output, enhances massage intensity, and at the same time distributes the load on single-stage gears, extending service life.

[0010] Preferably, positioning grooves are provided on both sides of the lower cover, and a positioning post is coaxially fixed at the bottom of the kneading gear. The positioning post can be installed inside the positioning groove, and multiple sets of lubrication grooves are provided at the positioning grooves on the lower cover.

[0011] By adopting the above technical solution, the bearing installation process is omitted, the manufacturing cost is reduced, and the positioning column achieves low-friction and stable rotation with the assistance of the lubrication groove.

[0012] Preferably, a plurality of snap-fit ​​blocks are fixedly connected to the top of the kneading gear, and a positioning block is also fixedly connected to the top of the kneading gear. A plurality of snap-fit ​​holes adapted to the snap-fit ​​blocks are opened at the bottom of the eccentric block, and a positioning hole adapted to the positioning block is also opened at the bottom of the eccentric block.

[0013] By adopting the above technical solution, the eccentric block and the kneading gear can be quickly and accurately engaged, which facilitates disassembly and maintenance and avoids transmission deviation.

[0014] Preferably, a copper insert is threaded onto the eccentric block, and a threaded hole is provided at the bottom of the massage head rocker arm. The massage head rocker arm is threaded onto the copper insert through the threaded hole. A stabilizing block is provided on the outside of the massage head rocker arm, and the stabilizing block can be engaged inside the limiting sleeve.

[0015] By adopting the above technical solution, the connection strength between the massage head rocker arm and the eccentric block is enhanced, and the stabilizing block inside the limiting sleeve constrains the movement trajectory to prevent shaking.

[0016] Preferably, the front side of the drive motor is also provided with a shock-absorbing pad, which can be snapped onto the mounting base.

[0017] By adopting the above technical solution, the high-frequency vibration energy of the motor is effectively absorbed, reducing the noise peak by more than 15dB and improving the user experience.

[0018] In summary, this application has the following beneficial technical effects: the multi-stage gear transmission system improves torque stability and ensures deep muscle massage effect; the modular snap-fit ​​structure simplifies the assembly process and reduces production costs by more than 30%; the shock-absorbing pad and lubrication groove work together to extend the service life of the equipment; the limit sleeve and stabilizing block provide dual constraints, keeping the massage trajectory error within ±0.5mm.

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0030] A neck massage mechanism includes a lower cover 1 and an upper cover 2. A mounting base 3 is provided on the lower cover 1, and a drive motor 4 is mounted on the mounting base 3. The drive motor 4 is a brushless motor, which does not generate significant noise during operation, thus improving the massage mechanism's effectiveness. A worm gear 5 is fixedly connected to the output shaft of the drive motor 4, enabling the drive motor 4 to drive the worm gear 5 to rotate continuously and stably. Two sets of double gears 6, meshing with the worm gear 5, are rotatably connected to the lower cover 1. Two sets of secondary transmission gears 7, meshing with the double gears 6, are also rotatably connected to the lower cover 1. Both sides are rotatably connected to kneading gears 8, and eccentric blocks 9 are engaged on the kneading gears 8. When the kneading gears 8 rotate at a constant speed, the eccentric blocks 9 rotate with them, and their upper parts make periodic movements. A massage head rocker arm 11 is connected to the top of the eccentric block 9, and a massage head is connected to the massage head rocker arm 11. When it is working, it controls the massage head to perform periodic massage on the user's shoulders and neck. A limiting sleeve 12 is connected to the upper cover 2. The limiting sleeve 12 is fitted on the outside of the massage head rocker arm 11 and the eccentric block 9, which can limit the movement trajectory of the massage head rocker arm 11, so that it can work on a specified trajectory.

[0031] Furthermore, both the double gear 6 and the secondary transmission gear 7 are coaxially arranged with upper and lower parts. The upper parts of the two sets of double gears 6 mesh with the worm gear 5, and the lower parts of the two sets of secondary transmission gears 7 mesh with the lower parts of the two sets of double gears 6 respectively. The upper part of the secondary transmission gear 7 meshes with the kneading gear 8. Through multi-stage transmission, the torque is increased, thereby enhancing the massage intensity.

[0032] Furthermore, positioning grooves 14 are provided on both sides of the lower cover 1, and positioning pins are coaxially fixed at the bottom of the kneading gear 8. The positioning pins can be installed inside the positioning grooves 14, thereby enabling the kneading gear 8 to rotate stably without the need for bearings, thus reducing the cost of use.

[0033] Furthermore, multiple sets of lubrication grooves 19 are provided at the positioning groove 14 on the lower cover 1, where an appropriate amount of lubricating grease can be applied to further enhance the rotation effect of the kneading gear 8.

[0034] Furthermore, multiple snap-fit ​​blocks 15 are fixedly connected to the top of the kneading gear 8, and a positioning block 16 is also fixedly connected to the top of the kneading gear 8. Multiple snap-fit ​​holes 18 that are compatible with the snap-fit ​​blocks 15 are opened at the bottom of the eccentric block 9, and a positioning hole 17 that is compatible with the positioning block 16 is also opened at the bottom of the eccentric block 9, which can facilitate the assembly of the eccentric block 9.

[0035] Furthermore, a copper insert 10 is threaded onto the eccentric block 9, and a threaded hole 20 is provided at the bottom of the massage head rocker arm 11. The massage head rocker arm 11 is threaded onto the copper insert 10 through the threaded hole 20. A stabilizing block 21 is provided on the outside of the massage head rocker arm 11, and the stabilizing block 21 can be engaged inside the limiting sleeve 12.

[0036] Furthermore, a shock-absorbing pad 13 is provided on the front side of the drive motor 4. The shock-absorbing pad 13 can be snapped onto the mounting base 3 to reduce vibration when the drive motor 4 is working, thereby improving the performance of the massage mechanism.

[0037] The implementation principle of this embodiment is as follows: the drive motor 4 drives the worm gear 5 to rotate, which drives the upper part of the two sets of double gears 6 to rotate. The power is transmitted to the secondary transmission gear 7 through the lower meshing, and finally drives the kneading gear 8 to rotate at a constant speed. The eccentric block 9 moves in a circular motion with the kneading gear 8, which drives the massage head rocker arm 11 to form an elliptical trajectory under the constraint of the limiting sleeve 12, simulating the kneading action of a human hand. The grease in the positioning groove 14 continuously lubricates the positioning column, and the shock-absorbing pad 13 suppresses the propagation of motor vibration.
