DETAILED DESCRIPTION

[0041] For example 1, please refer to Figures 1 to 12The present invention provides a massage mechanism structure, including a rotating shaft 1 and a housing 2. The housing 2 is composed of an upper shell 21 and a lower shell 22. The bottom of the upper shell 21 and the top of the lower shell 22 are both provided with a mounting platform 3 for mounting the rotating shaft 1. The mounting platform 3 is integrally formed on the housing 2 and has a recessed groove 4 that matches the outer diameter of the rotating shaft 1. After the upper shell 21 and the lower shell 22 are connected by screws, the recessed groove 4 on the upper shell 21 and the recessed groove 4 on the lower shell 22 form a mounting groove for receiving the rotating shaft 1. The rotating shaft 1 is rotatably connected in the mounting groove. Several oil storage grooves 41 are also provided on the inner wall of the recessed groove 4. The oil storage grooves 41 can store lubricating grease, reducing wear on the mounting groove and thus increasing the service life. The present invention incorporates mounting platforms 3 on the upper and lower shells 21 and 22, and defines recessed grooves 4 on these mounting platforms. This allows the conventional fixings 13 to be integrated into the housing 2, simplifying the structure and reducing component count. Furthermore, the recessed grooves 4 on either side of the housing 2 are formed directly into the housing 2, improving the installation accuracy of the shaft 1, avoiding assembly errors, reducing vibration and noise, and enhancing the efficiency and stability of the transmission system.

[0042] Specifically, the rotating shaft 1 is a kneading shaft 6 that drives the massage component 7 to perform a kneading action or a knocking shaft 8 that causes the massage component 7 to produce a knocking effect.

[0043] Specifically, it also includes a motor 5, a kneading shaft 6, a massage component 7, a knocking shaft 8 and a transmission mechanism 9. The motor 5 is installed inside the housing 2. The motor 5 is connected to the kneading shaft 6 and the knocking shaft 8 through the transmission mechanism 9. The massage component 7 is connected to the kneading shaft 6. There are two groups of massage components 7, and the two groups of massage components 7 are symmetrically arranged at both ends of the kneading shaft 6. The massage component 7 includes a massage head 71 and a massage arm 72 with a massage end. The massage end is provided with a rotating part 73, and the massage head 71 is rotatably connected to the rotating part 73. Each massage head 71 is rotatably connected to the massage arm 72. When the massage head 71 is in contact with the human body, it can roll in the direction of the force, reducing the sliding friction between the surface of the massage head 71 and the human body, and changing it to rolling friction. The friction is small, avoiding rubbing the surface of the human skin. In addition, multiple massage heads 71 ​​are in contact with the human skin, which increases the massage comfort and massage experience.

[0044] Specifically, the massage arms 72 are respectively divided into a shoulder and neck massage arm 721 and a trapezius massage arm 722. The shoulder and neck massage arm 721 has a shoulder massage end for massaging the shoulders and a neck massage end for massaging the neck. The trapezius massage arm 722 has a trapezius massage end for massaging the trapezius muscles of the human body.

[0045] The rotating part 73 is composed of a first rotating part 731, a second rotating part 732 and a third rotating part 733. The first rotating part 731 is provided at the shoulder massage end, the second rotating part 732 is provided at the neck massage end, and the third rotating part 733 is provided at the trapezius massage end.

[0046] The massage head 71 is divided into a shoulder massage head 711 , a neck massage head 712 and a trapezius massage head 713 . The shoulder massage head 711 is rotatably connected to the first rotating part 731 , the neck massage head 712 is rotatably connected to the second rotating part 732 , and the trapezius massage head 713 is rotatably connected to the third rotating part 733 .

[0047] The outer wall of the kneading shaft 6 is provided with an eccentric wheel assembly 10, which is composed of a first eccentric wheel 101, a second eccentric wheel 102 and an eccentric wheel cover 103 connected by screws; the first eccentric wheel 101 includes an eccentric boss portion 1011, the axis of the eccentric boss portion 1011 does not coincide with the axis of the kneading shaft 6, and a first flange portion 1012 is provided on one side of the eccentric boss portion 1011. The trapezius muscle massage arm 722 is sleeved on the eccentric boss portion 1011 and is sandwiched between the first flange portion 1012 and the second flange portion 1021;

[0048] The second eccentric wheel 102 includes a second flange portion 1021 and a deflection wheel 1022. The deflection wheel 1022 is disposed on a side of the second flange portion 1021 away from the eccentric cam portion. The side of the second flange portion 1021 away from the eccentric cam portion has an abutment surface that contacts the massage arm 72. The abutment surface is arranged at an angle to the axis of the kneading shaft 6, so that the axis of the deflection wheel 1022 forms an angle with the axis of the transmission shaft 92. The shoulder and neck massage arm 721 is sleeved on the outer wall of the deflection wheel 1022. After the deflection wheel cover 103 and the deflection wheel 1022 are fixed, the shoulder and neck massage arm 721 is clamped between the deflection wheel cover 103 and the second flange portion 1021. A guide rod is provided at the bottom of the shoulder and neck massage arm 721, and a guide groove is provided on the bottom shell of the massager. The guide rod is slidably connected to the guide groove to guide the massage action of the shoulder and neck massage arm 721.

[0049] When the kneading shaft 6 rotates, the trapezius massage arms 722 reciprocate in the vertical direction, and the massage ends of the shoulder and neck massage arms 721 reciprocate along the axis direction of the kneading shaft 6 .

[0050] Specifically, the transmission mechanism 9 includes a belt transmission assembly 91, a transmission shaft 92, a gear transmission assembly 93 and a worm gear transmission assembly 94. The belt transmission assembly 91 includes a driving pulley 911, a driven pulley 912 and a transmission belt 913. The driving pulley 911 is connected to the output shaft of the motor 5, and the driven pulley 912 is rotatably connected to the outer wall of the knocking shaft 8. The transmission belt 913 is wound around the driving pulley 911 and the driven pulley 912; a second bearing 19 is connected to the outside of the knocking shaft 8, and the second bearing is connected between the driven pulley 912 and the knocking shaft 8 for supporting the driven pulley 912.

[0051] The gear transmission assembly 93 includes a driving bevel gear 931 and a driven bevel gear 932 meshing with the driving bevel gear 931. The driving bevel gear 931 is rotatably connected to the outer wall of the knocking shaft 8. The side wall of the driven pulley 912 is provided with a first power transmission member 95 with an annular structure. The axis of the first power transmission member 95 coincides with the driven pulley 912. The driving bevel gear 931 is provided with a second power transmission member 96 with an annular structure. The axis of the second power transmission member 96 coincides with the driving bevel gear 931. The first power transmission member 95 and the second power transmission member 96 are fixedly connected to transmit power to the driving bevel gear 931. The inner wall of the first power transmission member 95 is provided with a one-way bearing 11, and the one-way bearing 11 is sleeved on the outside of the knocking shaft 8; the outside of the knocking shaft 8 is also connected to a composite bushing 12, and the composite bushing 12 is connected between the driving bevel gear 931 and the knocking shaft 8 for supporting the driving bevel gear 931.

[0052] The transmission shaft 92 is rotatably connected to the inside of the housing 2, the driven bevel gear 932 is connected to one end of the transmission shaft 92, and the worm gear transmission assembly 94 includes a worm wheel 941 and a worm 942. The worm 942 is connected to the other end of the transmission shaft 92, and the worm wheel 941 is fixedly connected to the outer wall of the kneading shaft 6. The worm wheel 941 and the worm 942 are meshed and connected.

[0053] The one-way bearing 11 can transmit force and torque in one direction and can rotate freely in the opposite direction.

[0054] If the user requires both kneading and tapping massage, the user can control the motor 5 to rotate in the forward direction (i.e., the direction in which the motor 5 rotates enables the one-way bearing 11 to transmit force and torque). The power of the motor 5 is then transmitted to the driven pulley 912 and the driving bevel gear 931 via the drive belt 913. Since the direction in which the drive motor 5 rotates enables the one-way bearing 11 to transmit force and torque, when the driven pulley 912 or the driving bevel gear 931 rotates, the tapping shaft 8 rotates along with them, and through the articulated seat 17 and articulated arm 18, the massage arm 72 produces a tapping massage effect. Simultaneously, the driving bevel gear 931 also drives the driven bevel gear 932 to rotate, which in turn drives the kneading shaft 6 via the drive shaft 92 and worm gear assembly 94, driving the kneading massage assembly to perform a massage action, thereby achieving simultaneous kneading and tapping massage.

[0055] When the motor 5 rotates in the reverse direction, the one-way bearing 11 rotates idly on the outer wall of the knocking transmission shaft 92, and the knocking shaft 8 stops rotating. The power of the motor 5 is transmitted to the driven pulley 912 and the driving bevel gear 931 via the transmission belt 913 (the driven pulley 912 also rotates idly on the outer wall of the knocking shaft 8 at this time). The driving bevel gear 931 drives the driven bevel gear 932 to rotate, and the kneading shaft 6 rotates via the transmission shaft 92 and the worm gear transmission assembly 94, thereby driving the kneading massage assembly to perform a massage action, thereby achieving kneading massage.

[0056] After the speed of the motor 5 output is decelerated by the belt drive assembly 91 and further decelerated by the gear drive assembly 93, the speed of the worm 942 is significantly slower than in the prior art. The slower the speed of the worm 942, the quieter the meshing sound of the worm 942 and the worm wheel 941, the smoother the transmission, and the lower the precision requirements for the worm wheel 941 and the worm 942. The output shaft of the motor 5 only needs to drive the driving pulley 911 to rotate. The output shaft of the motor 5 can be set relatively short, is less prone to bending and deformation, is easy to process, and ensures precision and strength.

[0057] The massage movement structure also includes a fixing part 13, which is fixedly connected to the casing. The fixing part 13 has a protruding end 131 on the side facing the meshing transmission mechanism 9, and a mounting hole 132 is provided on the protruding end 131. A first bearing 14 is connected to the mounting hole 132. The driven bevel gear 932 has a receiving hole on the side facing the fixing part 13. One end of the transmission shaft 92 passes through the driven bevel gear 932 and extends into the receiving hole, and the protruding end 131 is located in the receiving hole. The diameter of the receiving hole is larger than the protruding end 131, so that the protruding end 131 is accommodated in the receiving hole, and the protruding end 131 has no contact with the side wall of the receiving hole; one end of the transmission shaft 92 passes through the driven bevel gear 932 and is connected to the first bearing 14 installed inside the fixing part 13, which can make the driven bevel gear 932 and the transmission shaft 92 run more smoothly.

[0058] The fixing member 13 is provided with a through hole 133 passing through the fixing member 13 , and the axis of the through hole 133 is perpendicular to the axis of the protruding end 131 . When the fixing member 13 is installed inside the housing 2 , the knocking transmission shaft 92 is passed through the through hole 133 .

[0059] Specifically, the second power transmission member 96 has a connecting groove 961 that matches the first power transmission member 95. The first power transmission member 95 is connected to the connecting groove 961. The outer wall of the first power transmission member 95 is provided with a transmission protrusion 951. The transmission protrusion 951 extends in the axial direction of the first power transmission member 95. The inner wall of the connecting groove 961 is provided with a groove 962 that matches the transmission protrusion 951. When the second power transmission member 96 is connected to the first power transmission member 95, the transmission protrusion 951 is inserted into the groove 962. The transmission protrusion 951 and the groove 962 cooperate with each other, so that when the driven pulley 912 rotates, the driving bevel gear 931 rotates accordingly, thereby transmitting power to the gear transmission assembly 93 and the worm gear transmission assembly 94.

[0060] Specifically, it also includes a shaft end fixing sleeve 15, which is connected to the end of the output shaft of the motor 5. A fixing stud 23 is provided inside the housing 2, and the shaft end fixing sleeve 15 is provided with a fixing part 151. The fixing part 151 is connected to the fixing stud 23 through a fastener.

[0061] The inner wall of the shaft end fixing sleeve 15 also has several oil reservoirs. These reservoirs can store lubricating grease, reducing wear on the shaft end fixing sleeve 15 and thus increasing its service life. Alternatively, a third bearing (not shown) is provided on the inner wall of the shaft end fixing sleeve 15. The outer ring of the third bearing fits against the inner wall of the shaft end fixing sleeve 15, and the output shaft of the motor 5 is connected to the inner ring of the third bearing. The shaft end fixing sleeve 15 prevents the motor 5 from tilting due to the tension of the transmission belt 913.

[0062] Specifically, the housing 2 further includes a fixing bracket 16 for fixing the motor 5. The housing 2 has a mounting portion 24 inside, and the mounting portion 24 is provided with an assembly groove 241 that matches the fixing bracket 16. The fixing bracket 16 is disposed in the assembly groove 241, and the outer wall of the fixing bracket 16 is aligned with the inner wall of the assembly groove 241. After the upper shell 21 and the upper shell 21 are fixedly connected by screws, the fixing bracket 16 is fixed in the assembly groove 241, and the assembly groove 241 has at least one first plane 242. The side of the fixing bracket 16 has a second plane 161. When the fixing bracket 16 is installed in the assembly groove 241, the first plane 242 and the second plane 161 are aligned. The alignment of the first plane 242 and the second plane 161 can prevent the motor 5 and the fixing plate from rotating circumferentially after the motor 5 is started. The fixing bracket 16 and the assembly slot 241 are fitted with a clearance fit, a transition fit, or an interference fit, allowing the fixing bracket 16 to slide into or be pressed into the assembly slot 241. The present invention's motor 5 securing structure eliminates the need for screws securing the fixing bracket 16 and the lower housing 22. In the present invention, the fixing bracket 16 can be directly slid into the assembly slot 241 on the lower housing 22 (or can be pressed into the assembly slot 241 on the lower housing 22 with an interference fit). The upper and lower housings 21 and 22 are then fastened and locked together, simplifying the structure and saving parts.

[0063] Two first studs 25 are also provided within the lower housing 22, one on each side of the mounting portion 24. Two screw holes 211 are provided within the upper housing 21, corresponding one to each of the first studs 25. The two screws pass through the screw holes 211 and are screwed together with the first studs 25. The first studs 25 are integrally formed with the mounting portion 24. This integrated formation of the mounting portion 24 and first studs 25 makes the internal structure of the housing more compact, reducing the size of the massage mechanism.

[0064] Specifically, it also includes an articulated seat 17, which is eccentrically installed at the end of the knocking shaft 8. The articulated seat 17 is hinged with an articulated arm 18. The bottom of the massage arm 72 is provided with an assembly ring 723, and the assembly ring 723 is provided with a receiving groove. The end of the articulated arm 18 away from the articulated seat 17 is ball-hinged in the receiving groove.

[0065] In the second embodiment, the present invention provides a massager including the massage core structure in the first embodiment.

[0066] The present invention provides a mounting platform 3 on the upper shell 21 and the lower shell 22, and defines a recessed groove 4 on the mounting platform 3, thereby integrating the fixing member 13 of the prior art into the shell 2 and forming the whole body, thereby simplifying the structure and saving parts. In addition, the recessed grooves 4 on both sides of the shell 2 are directly formed on the shell 2, which can improve the installation accuracy of the rotating shaft 1, avoid assembly errors, reduce vibration and noise, and improve the working efficiency and stability of the transmission system. In addition, each massage head 71 is rotatably connected to the massage arm 72.
