DETAILED DESCRIPTION

[0032] For example 1, please refer to Figures 1 to 7 The present invention provides a massage movement structure, including a motor 1, a housing 2 and a fixing frame 3, the motor 1 and the fixing frame 3 are fixedly connected, the housing 2 is composed of a first shell 21 and a second shell 22 connected by screws, the first shell 21 has a mounting portion 23 inside, the mounting portion 23 is provided with an assembly groove 231 matching the fixing frame 3, the fixing frame 3 is arranged in the assembly groove 231, and the outer wall of the fixing frame 3 is in contact with the inner wall of the assembly groove 231. After the first shell 21 and the second shell 22 are fixedly connected by screws, the fixing frame 3 is fixed in the assembly groove 231.

[0033] Specifically, the fitting relationship between the fixing frame 3 and the assembly groove 231 is a clearance fit, a transition fit, or an interference fit, so that the fixing frame 3 slides and is mounted in the assembly groove 231 or is pressed into the assembly groove 231. Compared to the fixing structure of the motor fixing frame 3 in the prior art, the fixing structure of the fixing frame 3 of the present invention can eliminate the screws that fix the motor fixing frame 3 and the lower shell. In the present invention, the fixing frame 3 can be directly slid and mounted into the assembly groove 231 on the first shell 21 (it can also be pressed into the assembly groove 231 on the first shell 21 through an interference fit), and then the first shell 21 and the second shell 22 are fastened and locked together, simplifying the structure and saving parts.

[0034] Specifically, the assembly groove 231 has at least one first plane 232, and the side of the fixing frame 3 has a second plane 31. When the fixing frame 3 is installed in the assembly groove 231, the first plane 232 and the second plane 31 are in contact with each other. The first plane 232 is arranged on the side wall of the assembly groove 231 in the front-to-back direction, and the first plane 232 is arranged on the side wall of the fixing frame 3 in the front-to-back direction. The front-to-back direction in the present utility model is the direction perpendicular to the axis of the kneading shaft 5 or the knocking transmission shaft 6 in the horizontal plane. The left-right direction is the direction of the axis of the kneading shaft 5 or the knocking transmission shaft 6, and the up-down direction is the direction perpendicular to the horizontal plane. By making the first plane 232 and the second plane 31 in contact with each other, the motor 1 and the fixing plate can be prevented from circumferential rotation after the motor 1 is started.

[0035] Specifically, two first studs 24 are disposed within the first housing 21, one on each side of the mounting portion 23. Two second screw holes 25 are disposed within the second housing 22, corresponding one-to-one with the first studs 24. The two screws pass through the second screw holes 25 and are screwed together with the first studs 24. The first studs 24 are integrally formed with the mounting portion 23. The integrally formed mounting portion 23 and first studs 24 make the internal structure of the housing 2 more compact, thereby reducing the size of the massage mechanism.

[0036] Specifically, the motor 1 further includes a shaft end fixing sleeve 4 connected to the end of the output shaft of the motor 1. A third stud 26 is disposed within the first housing 21. The shaft end fixing sleeve 4 includes a fixing portion 41 connected to the third stud 26 via a fastener. The shaft end fixing sleeve 4 prevents the motor 1 from tilting due to the tension of the transmission belt 73.

[0037] Specifically, the inner wall of the shaft end fixing sleeve 4 is provided with a plurality of oil storage grooves 42. The oil storage grooves 42 can store lubricating grease to reduce the wear of the shaft end fixing sleeve 4 and increase the service life.

[0038] Or a third bearing (not shown) is provided on the inner wall of the shaft end fixing sleeve 4, the outer ring of the third bearing fits the inner wall of the shaft end fixing sleeve 4, and the output shaft of the motor 1 is connected to the inner ring of the third bearing.

[0039] Specifically, it also includes a kneading shaft 5, a knocking transmission shaft 6, a belt drive assembly 7 and a meshing transmission mechanism. The kneading shaft 5 and the knocking shaft are both rotatably connected to the housing 2. One end of the belt drive assembly 7 is connected to the output shaft of the motor 1, and the other end of the belt drive assembly 7 is connected to the knocking transmission shaft 6. One end of the meshing transmission mechanism is connected to the knocking transmission shaft 6, and the other end of the meshing transmission mechanism is connected to the kneading shaft 5. The belt drive assembly 7 is provided with a first power transmission member 8, and the meshing transmission mechanism is provided with a second power transmission member 9. The first power transmission member 8 is connected to the second power transmission member 9 to transmit power to the meshing transmission mechanism.

[0040] Specifically, the belt transmission assembly 7 includes a driving pulley 71, a driven pulley 72 and a transmission belt 73. The driving pulley 71 is connected to the output shaft of the motor 1, and the driven pulley 72 is rotatably connected to the outside of the knocking transmission shaft 6. The transmission belt 73 is wound between the driving pulley 71 and the driven pulley 72. The first power transmission member 8 is sleeved on the outside of the knocking transmission shaft 6, and the first power transmission member 8 is fixedly connected to the driven pulley 72. The outer wall of the knocking transmission shaft 6 is further provided with a one-way bearing 10, and the outer wall of the one-way bearing 10 is in contact with the inner wall of the first power transmission member 8; the outer side of the knocking transmission shaft 6 is connected to a second bearing 11, and the second bearing 11 is connected between the driven pulley 72 and the knocking shaft for supporting the driven pulley 72;

[0041] The one-way bearing 10 is capable of transmitting force and torque in one direction and is free to rotate in the opposite direction.

[0042] If the user requires both kneading and tapping massage, the user can control the motor 1 by rotating it in the forward direction (i.e., the direction in which the motor 1 rotates enables the one-way bearing 10 to transmit force and torque). The power of the motor 1 is then transmitted to the driven pulley 72 and the driving bevel gear 121 via the transmission belt 73. Since the direction in which the drive motor 1 rotates enables the one-way bearing 10 to transmit force and torque, when the driven pulley 72 or the driving bevel gear 121 rotates, the tapping transmission shaft 6 can rotate along with the driven pulley 72 or the driving bevel gear 121, causing the tapping massage mechanism to perform the corresponding massage action. Simultaneously, the driving bevel gear 121 also drives the driven bevel gear 122 to rotate, and the kneading shaft 5 also rotates via the transmission shaft 13 and the worm gear transmission assembly 14, driving the kneading massage assembly to perform the massage action, thereby achieving simultaneous kneading and tapping massage.

[0043] When the motor 1 rotates in the reverse direction, the one-way bearing 10 idles while striking the outer wall of the transmission shaft 6, and the transmission shaft 6 stops rotating. The power of the motor 1 is transmitted to the driven pulley 72 and the driving bevel gear 121 via the transmission belt 73 (the driven pulley 72 also idles while striking the outer wall of the transmission shaft 6). The driving bevel gear 121 drives the driven bevel gear 122 to rotate, and the kneading shaft 5 rotates via the transmission shaft 13 and the worm gear transmission assembly 14, thereby driving the kneading massage assembly to perform a massage action, thereby achieving kneading massage.

[0044] The meshing transmission mechanism includes a gear transmission assembly 12, a transmission shaft 13 and a worm gear transmission assembly 14. The gear transmission assembly 12 includes a driving bevel gear 121 and a driven bevel gear 122 meshing with the driving bevel gear 121. The driving bevel gear 121 is connected to the outer wall of the knocking transmission shaft 6. The second power transmission member 9 is arranged on the side wall of the driving bevel gear 121. The transmission shaft 13 is rotatably connected to the inside of the housing 2. The driven bevel gear 122 is fixed to one end of the transmission shaft 13. The worm gear transmission assembly 14 includes a worm 141 and a worm wheel 142. The worm 141 is fixedly connected to the transmission shaft 13. The worm wheel 142 is fixed to the outer wall of the kneading shaft 5. The worm 141 and the worm wheel 142 are meshingly connected. A composite bushing 15 is also connected to the outside of the knocking transmission shaft 6. The composite bushing 15 is connected between the driving bevel gear 121 and the knocking shaft to support the driving bevel gear 121.

[0045] The structure also includes a fixing member 16, which is fixedly connected to the housing 2. The fixing member 16 has a protruding end 161 on the side facing the meshing transmission mechanism, and a mounting hole 162 is provided on the protruding end 161. A first bearing 17 is connected to the mounting hole 162. The driven bevel gear 122 has a receiving hole on the side facing the fixing member 16. One end of the transmission shaft 13 passes through the driven bevel gear 122 and extends into the receiving hole, and the protruding end 161 is located in the receiving hole. The diameter of the receiving hole is larger than the protruding end 161, so that the protruding end 161 is received in the receiving hole, and the protruding end 161 has no contact with the side wall of the receiving hole; the arrangement in which one end of the transmission shaft 13 passes through the driven bevel gear 122 and is connected to the first bearing 17 installed inside the fixing member 16 can make the driven bevel gear 122 and the transmission shaft 13 run more smoothly.

[0046] The fixing member 16 is provided with a through hole 163 passing through the fixing member 16 , and the axis of the through hole 163 is perpendicular to the axis of the protruding end 161 . When the fixing member 16 is installed inside the housing, the knocking transmission shaft 6 is passed through the through hole 163 .

[0047] After the speed of the motor 1 output is decelerated by the belt drive assembly 7 and further decelerated by the gear drive assembly 12, the speed of the worm 141 is significantly slower than in the prior art. The slower the speed of the worm 141, the quieter the meshing sound between the worm 141 and the worm wheel 142, the smoother the transmission, and the lower the precision requirements for the worm wheel 142 and the worm 141. The output shaft of the motor 1 only needs to drive the driving pulley 71, so the output shaft of the motor 1 can be set relatively short, less prone to bending and deformation, and easier to machine while ensuring precision and strength.

[0048] Specifically, the second power transmission member 9 has a connecting groove 91 that matches the first power transmission member 8. The first power transmission member 8 is connected to the connecting groove 91. The outer wall of the first power transmission member 8 is provided with a transmission protrusion 81, which extends in the axial direction of the first power transmission member 8. The inner wall of the connecting groove 91 is provided with a groove 92 that matches the transmission protrusion 81. When the second power transmission member 9 is connected to the first power transmission member 8, the transmission protrusion 81 is inserted into the groove 92. The transmission protrusion 81 and the groove 92 cooperate with each other, so that when the driven pulley 72 rotates, the driving bevel gear 121 rotates accordingly, thereby transmitting power to the meshing transmission mechanism.

[0049] In the second embodiment, the present invention provides a massager including the massage core structure in the first embodiment.

[0050] Compared to the prior art fixing structure for the fixing bracket 3 of the motor 1, the fixing bracket 3 of the present invention eliminates the screws used to secure the fixing bracket 3 to the lower housing of the motor 1. In the present invention, the fixing bracket 3 can be directly slidably mounted into the assembly slot 231 of the first housing 21 (or can be press-fitted into the assembly slot 231 of the first housing 21 through an interference fit). The first housing 21 and the second housing 22 are then fastened and locked together, simplifying the structure and saving parts.

[0051] Although the specific implementation methods of the present invention are described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and are not intended to limit the scope of the present invention.
