[0016] The specific implementation of the utility model is described in detail below in combination with the drawings:

[0017] In the description of the utility model, it is understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0018] The utility model discloses a multifunctional massage movement, including a housing 1, on which are provided a kneading arm 2, a massage arm 3, an inclined eccentric wheel 4 for driving the kneading arm 2 to knead, an eccentric cam 5 for driving the massage arm 3 to massage, and a drive motor 6 for driving the inclined eccentric wheel 4 and the eccentric cam 5 to rotate. A rotating shaft 7 is rotatably provided on the housing 1, and the rotating shaft 7 is linked with the output shaft of the drive motor 6. The inclined eccentric wheel 4 and the eccentric cam 5 are sleeved on the rotating shaft 7 and are connected to the rotating shaft 7. It rotates synchronously, the kneading arm 2 is sleeved on the inclined eccentric wheel 4, and a guide groove 9 is provided on the housing 1 corresponding to the bottom of the kneading arm 2, and a guide member 8 is provided on the kneading arm 2 (the guide member 8 is most preferably a guide rod), and the guide member 8 guides and slides in the guide groove 9. A transmission arm 10 is sleeved on the eccentric cam 5, and the end of the transmission arm 10 away from the eccentric cam 5 is hinged to the massage arm 3. In the embodiment of the present utility model, an eccentric shaft 11 and a transmission shaft 12 are rotatably provided on the housing 1 ( The eccentric shaft 11 is provided with an eccentric section on the shaft body, and the eccentric section corresponds to the position of the massage arm 3. At this time, when the eccentric section rotates relative to each other, the massage arm 3 can be driven to move in series to achieve a shaking effect, thereby achieving a percussion massage). The bottom of the massage arm 3 is sleeved on the eccentric shaft 11, and the transmission shaft 12 is linked with the output shaft of the drive motor 6. The transmission shaft 12 is sleeved with a first transmission wheel 13, and also includes a second transmission wheel 14 which is sleeved on the rotating shaft 7 and can rotate relative to the rotating shaft 7. The second transmission wheel 14 is linked with the first transmission wheel 13, and the radius of the first transmission wheel 13 is greater than the radius of the second transmission wheel 14, forming a primary acceleration structure. The rotating shaft 7 is also provided with a first rotating wheel 15, which is fixedly connected to or integrally provided on the second transmission wheel 14. The eccentric shaft 11 is provided with a second rotating wheel 16 which is linked with the first rotating wheel 15. The radius of the first rotating wheel 15 is greater than the radius of the second rotating wheel 16, forming a secondary acceleration structure.

[0019] With the above technical solution, when working, the driving motor 6 preferably adopts a gear set to drive the rotating shaft 7 to rotate, and gears are set on the rotating shaft 7 and the transmission shaft 12. The number of teeth of the gears on the rotating shaft 7 is greater than the number of teeth of the gears on the transmission shaft 12, which can reduce the rotation speed of the rotating shaft 7, making kneading more comfortable. When the rotating shaft 7 rotates, the massage effect of kneading and massage can be achieved, and the second transmission wheel 14 can rotate relative to the rotating shaft 7, so it can speed up and drive independently by itself, and the first transmission wheel 13 drives the second transmission wheel 14 to achieve the first-level acceleration, and then the first rotating wheel 15 drives the second rotating wheel 16 to perform the second-level acceleration, thereby increasing the rotation speed of the eccentric shaft 11 alone and increasing the frequency of knocking.

[0020] A worm segment 17 is provided on the output shaft of the driving motor 6, and a one-way bearing is provided on the transmission shaft 12 (the one-way bearing is covered by the worm gear and is not shown in the figure), and a worm gear 18 is provided on the one-way bearing to engage with the worm segment 17, and a first gear 19 is provided on the worm gear 18 to rotate synchronously with the worm segment 17, and a second gear 20 is provided on the rotating shaft 7 to rotate synchronously with the rotating shaft 7 (the number of teeth of the first gear 19 is preferably less than the number of teeth of the second gear 20), and the first gear 19 and the second gear 20 are engaged. In this way, the driving motor 6 is in two driving states in forward and reverse rotation. When the driving motor 6 is in forward and reverse rotation, the first gear 19 and the second gear 20 are engaged. When the motor 6 rotates forward, it drives the worm gear 18 to rotate, and further drives the inner and outer rings of the one-way bearing to rotate at the same time, thereby driving the transmission shaft 12 to rotate. The transmission shaft 12 drives the first transmission wheel 13 to rotate to achieve the effect of percussion massage. When the drive motor 6 rotates in the reverse direction, the inner and outer rings of the one-way bearing are in a slipping state. At this time, the transmission shaft 12 does not move, thereby stopping the percussion massage. Of course, the one-way bearing can also be set at the first transmission wheel 13. In this way, the transmission shaft 12 will rotate regardless of whether the drive motor 6 rotates forward or reversed. When percussion is not required, the energy consumption is relatively high.

[0021] The first rotating wheel 15 and the second rotating wheel 16 are both pulleys, and the first rotating wheel 15 and the second rotating wheel 16 are linked via a belt 21. Because the distance between the rotating shaft 7 and the eccentric shaft 11 is large, if gear engagement is directly adopted, linkage through a gear set is required, and the stability of gear rotation must also be considered. The internal structure can be simplified by using a belt. Of course, the first rotating wheel 15 and the second rotating wheel 16 can also be driven by gear engagement, but it will increase internal components and make the interior more crowded.

[0022] The first transmission wheel 13 and the second transmission wheel 14 are gears, and the first transmission wheel 13 and the second transmission wheel 14 are meshed. The structure of the gear meshing is relatively simple, and it is also more convenient to install and has better stability during use. Of course, the first transmission wheel 13 and the second transmission wheel 14 can also be pulleys.
