[0031] See also Figures 1 to 7 The utility model provides a fascia vibration massager, which includes a massage component 1, a shell 2, and a motor 3 and a transmission shaft 4 installed in the inner cavity of the shell 2. The output end of the motor 3 is connected to the transmission shaft 4 through a flexible transmission component 5. The flexible transmission component 5 is a belt drive structure. The transmission shaft 4 is connected to an eccentric wheel 6, and the massage component 1 is connected to the eccentric wheel 6.

[0032] In this embodiment, the motor 3 adopts a small-diameter, high-speed, low-torque motor. For example, the rated speed of the motor is 4000-5000r / min. Of course, the speed of the motor is not limited to this, and motors with other rated speeds can also be selected. The flexible transmission component 5 makes the speed of the transmission shaft less than the output speed of the motor, that is, after the motor is transmitted by the flexible transmission component 5, the speed of the transmission shaft is less than the output speed of the motor. For example, when the rated speed of the motor is 4000-5000r / min, after deceleration by the flexible transmission component 5, the speed of the transmission shaft is 2000r / min. At this time, the reduction ratio of the flexible transmission component 5 is 2-2.5:1. Of course, the flexible transmission component 5 can also be configured with other reduction ratios, such as 5:1 or 10:1. As long as the speed of the transmission shaft can be made less than the output speed of the motor, it is within the protection scope of this utility model.

[0033] In the prior art, using a motor directly to drive an eccentric requires a high-torque motor. The greater the rated torque, the larger the motor. Therefore, using a motor directly to drive an eccentric results in a thicker massager. However, the present invention utilizes a high-speed, low-torque motor, which reduces the motor diameter and saves space. This allows for a thinner overall thickness compared to prior art massagers.

[0034] The motor 3 drives the transmission shaft 4 to rotate through the flexible transmission assembly 5. After the flexible transmission assembly 5 is decelerated, the torque of the transmission shaft 4 is increased. The transmission shaft 4 vibrates the massage assembly 1 through the eccentric wheel 6 to achieve the purpose of relaxing the soft tissue of the human body.

[0035] Specifically, the flexible transmission assembly 5 includes a first pulley 51, a second pulley 52 and a transmission belt 53. The first pulley 51 is connected to the output end of the motor 3, the second pulley 52 is connected to the transmission shaft 4, and the transmission belt 53 is wound around the outer walls of the first pulley 51 and the second pulley 52. ​​The second pulley 52 is connected to the middle of the transmission shaft 4, and the two eccentric wheels are respectively installed at both ends of the transmission shaft 4. The use of a belt drive between the motor and the transmission shaft avoids the direct connection of the motor shaft to the eccentric wheel, which causes resonance between the motor body and the housing after high-speed rotation, reduces noise, and saves the shock-absorbing rubber sleeve outside the motor body. In addition, the belt drive itself can mitigate the impact of the load, and runs smoothly, with low noise and low vibration, which reduces the resonance noise of the fascia vibration as a whole. The belt drive has a simple structure and is easy to adjust.

[0036] Specifically, there are two massage components 1 and two eccentric wheels 6, respectively. The two eccentric wheels 6 are respectively arranged at both ends of the transmission shaft 4. Each eccentric wheel 6 is connected to a massage component 1. The massager has a center plane 7, and the two massage components 1 are symmetrical about the center plane 7. Of course, the two eccentric wheels 6 are also symmetrical about the center plane 7.

[0037] Specifically, the shell 2 is composed of an upper shell 21 and a lower shell 22. After the upper shell 21 and the lower shell 22 are connected, an installation cavity for placing the motor 3, the transmission shaft 4, the flexible transmission component 5 and the massage component 1 is formed between the upper shell 21 and the lower shell 22. The transmission shaft 4 is rotatably connected in the installation cavity through the first bearing 16, and the massage end of the massage component 1 extends through the upper shell 21 to the outside of the installation cavity.

[0038] Specifically, the massage component 1 includes a vibration frame 101 and massage balls 102. Each massage component includes a vibration frame 101 and two massage balls 102 connected to the vibration frame 101. The upper shell 21 is provided with a through hole 23. A total of four through holes 23 are provided on the upper shell 21. The upper end of the vibration frame 101 extends to the outside of the shell 2 through the through hole 23, and the massage ball 102 is sleeved on the upper end of the vibration frame 101.

[0039] Specifically, the vibration frame 101 is composed of a ring sleeve 1011 and a curved rod 1012 and a straight rod 1013 connected to the outside of the ring sleeve 1011. The curved rod 1012 and the straight rod 1013 extend to the outside of the housing 2 through corresponding through holes 23. The two massage balls 102 in each massage component are respectively connected to the upper ends of the curved rod 1012 and the straight rod 1013. The ring sleeve 1011 is connected to the eccentric wheel 6. The ring sleeve 1011 and the eccentric wheel 6 are connected via a second bearing 17. The inner ring of the second bearing 17 is fixedly connected to the eccentric portion of the eccentric wheel 6, and the outer ring of the second bearing is fixed inside the ring sleeve 1011.

[0040] Specifically, it also includes a soft rubber sleeve 8 that matches the through hole 23. The outer diameter of the soft rubber sleeve 8 matches the aperture of the through hole. The number of the soft rubber sleeves 8 is equal to the number of through holes. The soft rubber sleeve 8 is made of soft rubber material. On the one hand, the soft rubber sleeve 8 plays the role of elastic support for the vibration frame. On the other hand, the soft rubber sleeve can close the gap between the curved rod 1012 and the straight rod 1013 and the side wall of the through hole to prevent dust from entering the interior of the shell. The lower end of the soft rubber sleeve 8 is fixed in the installation cavity, and the upper end of the soft rubber sleeve 8 extends through the through hole 23 to the outer wall of the shell 2. The upper ends of the curved rod 1012 and the straight rod 1013 respectively extend through the corresponding soft rubber sleeves 8 to the outer wall of the shell 2.

[0041] Specifically, it also includes a battery 9 for powering the massager and a control board 10 for controlling the massager, and the battery 9 and the control board 10 are both arranged inside the shell 2. The battery 9 is connected to the motor, and a charging interface module is provided on the control board 10, and the battery 9 and the charging interface module are connected. At the same time, the control board is also connected to the motor to control the start and stop of the motor and adjust the speed. By adjusting the motor speed, the massager can generate different impact frequencies and achieve different massage intensities. Notches 24 are respectively provided on the opposite sides of the upper shell 21 and the lower shell 22. After the upper shell 21 and the lower shell 22 are fixedly connected, the two notches 24 form a notch that matches the control board 10, and the button surface cover 11 is connected to the notch.

[0042] Specifically, the control panel 10 is provided with at least three button modules 12, each of which is connected to a button soft glue 13, and the button surface cover 11 is provided with a plurality of through holes 111, each of which corresponds to the button module 12 one by one, and each of the button soft glue 13 extends to the outside of the button surface cover 11 through the through hole 111. The three button modules 12 are respectively a switch button module and two adjustment button modules for adjusting the massage intensity. According to the speed of the motor output speed during massage, this massager can divide the motor speed into several massage gears, and the two adjustment button modules are used to increase or decrease the massage gears respectively. In addition, the control panel 10 is also connected to a display module, which is used to display the current massage gear.

[0043] Specifically, the lower housing 22 has recessed grooves 14 on either side, each of which is provided with a crossbar 15. The shoulder straps connected to the massager are wrapped around the crossbars 15. The massager can be secured to the area requiring massage by grasping the shoulder straps with both hands. For example, the massager can be placed on the back of the shoulder, with the shoulder straps extending around the shoulder to the front of the body. The massager can then be secured to the back of the shoulder by grasping the shoulder straps with both hands. Alternatively, the massager can be secured to the area requiring massage by tying the two shoulder straps to the body. For example, the two shoulder straps can be tied around the arm to achieve arm massage.

[0044] The advantages of the present invention are that the motor and the transmission shaft are driven by a belt, which can avoid the motor shaft being directly connected to the eccentric wheel, avoid the resonance between the motor body and the housing caused by the high-speed rotation of the motor, reduce noise, and save the shock-absorbing rubber sleeve outside the motor body. In the present invention, a high-speed, low-torque motor is used, and after the belt drive, the torque of the motor is amplified so that the massage component can relax the soft tissue of the human body normally. In addition, the use of a low-torque motor reduces the diameter of the motor, which can save space and volume. Compared with the massagers in the prior art, the entire thickness of this massager can be made thinner. The belt drive between the motor and the transmission shaft can alleviate the load impact, and the operation is stable, low-noise, and low-vibration, which reduces the resonance noise of the vibration as a whole. The belt drive has a simple structure and is easy to adjust.
