[0038] like Figures 1-5 The massage mechanism shown includes a base 1, a massage execution unit, and a massage drive unit.

[0039] The base 1 serves as the carrier of the entire massage mechanism, and the massage execution unit and massage drive unit are both mounted on the base 1.

[0040] The massage execution unit includes a drive shaft 20, a left massage plate 21, and a right massage plate 22. The drive shaft 20 is rotatably supported on the base 1; both the left and right massage plates 21 and 22 are connected to the drive shaft 20.

The kneading shaft sleeve 31 is an eccentric shaft sleeve. The kneading shaft sleeve 31 is connected with the transmission shaft 20. The left massage plate 21 and the right massage plate 22 are respectively connected with one kneading shaft sleeve 31. The kneading driving component 30 drives the left massage plate 21 and the right massage plate 22 to reciprocate through the kneading shaft sleeve 31. In the figure, the kneading shaft sleeve 31 makes the axis of the left massage plate 21 and the right massage plate 22 not coincide with the axis of the transmission shaft 20. The axis of the left massage plate 21 and the right massage plate 22 forms an included angle greater than 0° with the transmission shaft 20, thereby driving the kneading action of the left massage plate 21 and the right massage plate 22.

[0042] In the embodiment, the massage mechanism further comprises an adjusting unit. The adjusting unit is used to adjust the distance between the left massage plate 21 and the right massage plate 22. Specifically, the adjusting unit is also installed on the base 1. The adjusting unit comprises a shell 40, an adjusting driving component 41, a transmission component 42, a left sleeve component 43 and a right sleeve component 44. Wherein:

[0043] The shell 40 is fixed on the base 1 and is located between the left massage plate 21 and the right massage plate 22. The adjusting driving component 41, the adjusting shaft 42, the transmission component 43, the left sleeve component 44 and the right sleeve component 45 are all arranged in the shell 40.

[0044] The adjusting driving component 41 can be selected as a motor. The adjusting shaft 42 is connected with the shell 40.

[0045] The transmission component 43 is connected with the adjusting shaft 42. The transmission component 43 has a main transmission part 430, a left transmission tooth part 431 and a right transmission tooth part 432. The left transmission tooth part 431 and the right transmission tooth part 432 are respectively connected with the left side and the right side of the main transmission part 430. The main transmission part 430 is in transmission cooperation with the output shaft of the adjusting driving component 41.

[0046] The left sleeve component 44 is sleeved on the transmission shaft 20. The left sleeve component 44 has a left sleeve gear 440 and a left sleeve body 441. The left sleeve body 441 is connected with the left side of the left sleeve gear 440. The left sleeve gear 440 is in mesh with the left transmission tooth part 431. The left sleeve body 441 is in cooperation with the shell 40 through left screw thread. The left end of the left sleeve body 441 extends out of the shell 40 and is connected with the left massage plate 21. Specifically, the left sleeve body 441 is connected with the kneading shaft sleeve 31 of the left massage plate 21.

[0047] The right sleeve 45 is sleeved on the transmission shaft 20, and only sleeved. The right sleeve 45 has a right sleeve gear 450 and a right sleeve body 451. The right sleeve body 451 is connected to the right side of the right sleeve gear 450. The right sleeve gear 450 is engaged with the right transmission tooth portion 432. The right sleeve body 451 is threadedly connected to the shell 40. The right end of the right sleeve body 451 extends out of the shell 40 and is connected to the right massage plate 22. Specifically, the right sleeve body 451 is connected to the kneading shaft sleeve 31 of the right massage plate 22.

[0048] In the embodiment, in order to facilitate the transmission of each component and make the layout of each component more compact and reasonable, the extension direction of the rotating shaft of the output shaft of the adjusting driving component 41 is perpendicular to the extension direction of the rotating shaft of the transmission component 43. For example, the output shaft of the adjusting driving component 41 adopts a worm, and the main transmission portion 430 adopts a worm gear. The transmission is completed by the engagement of the worm and the worm gear. In addition, the diameter of the main transmission portion 430 is greater than the diameter of the left transmission tooth portion 431 and the right transmission tooth portion 432. The diameter of the left sleeve gear 440 is greater than the diameter of the left sleeve body 441. The diameter of the right sleeve gear 450 is greater than the diameter of the right sleeve body 451.

[0049] When it is necessary to adjust the distance between the left massage plate 21 and the right massage plate 22, the adjusting driving component 41 is started. The adjusting driving component 41 drives the left transmission tooth portion 431 and the right transmission tooth portion 432 to rotate through the main transmission portion 430, and then drives the left sleeve gear 440 and the right sleeve gear 450 to rotate. Since the left sleeve body 441 and the right sleeve body 451 are threadedly connected to the shell 40, the left sleeve gear 440 and the right sleeve gear 450 are driven to move in the same direction or in the opposite direction while rotating. The movement of the left sleeve gear 440 and the right sleeve gear 450 drives the left massage plate 21 and the right massage plate 22 connected to the kneading shaft sleeve 31 to move in the same direction or in the opposite direction, so as to adjust the distance between the left massage plate 21 and the right massage plate 22. The movement of the left massage plate 21 and the right massage plate 22 in the same direction or in the opposite direction can be realized by adjusting the forward rotation and the reverse rotation of the adjusting driving component 41.

[0050] Since the left sleeve gear 440 and the right sleeve gear 450 move while rotating relative to the transmission component 43, in order to ensure the engagement of the left sleeve gear 440 and the right sleeve gear 450 with the left transmission tooth portion 431 and the right transmission tooth portion 432, a movement limiting structure needs to be arranged. In the embodiment, a pin 200 is arranged on the transmission shaft 20, and a groove body 310 is arranged on the kneading shaft sleeve 31. The groove body 310 extends along the axial direction of the transmission shaft 20, and the pin 200 is located in the groove body 310. The pin 200 abuts against both ends of the groove body 310, so as to limit the movement position of the kneading shaft sleeve 31 and further limit the adjusting distance of the left massage plate 21 and the right massage plate 22.

[0051] In addition, the massage mechanism of the embodiment is used as a mechanism for massaging the shoulder and back, and the massage mechanism further comprises a moving driving unit, which is also installed on the base 1 and is used to drive the base 1 to move so as to adjust the position of the whole massage mechanism. Figure 1 , 3 As shown in the drawings: the moving driving unit comprises a moving driving part 50, a moving shaft 51 and a moving wheel 52. The moving driving part 50 is connected with the moving shaft 51 and is used to drive the moving shaft 51 to rotate. The moving driving part 50 is connected with one end of the moving shaft 51, and the moving driving part 50 can be a motor. The moving shaft 51 is rotatably connected with the base 1. The moving wheel 52 is connected with two ends of the moving shaft 51, and the moving wheel 52 can be a gear, which is used to cooperate with a rack on the massage support. The meshing of the gear and the rack drives the whole massage mechanism to move.

[0052] The above embodiment is only used for illustrating the technical concept and characteristics of the present application, and the purpose is to enable the person skilled in the art to understand the content of the present application and to implement it, and it cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
