Specifically, the first housing 43 and the second housing 44 are respectively provided with a semicircular groove, and the first fixing groove 41 and the second fixing groove 42 are respectively formed after being butted. The gear mechanism 30 is mounted to the main body 40 through a fixing bearing and a fixing groove, reducing friction between the gear mechanism 30 and the main body 40.

Since the two massage mechanisms 10 are respectively connected to two ends of the transmission shaft 321 in a transmission manner and are symmetrically distributed, the main body 40 may include a connection portion and two extension portions disposed at two sides of the connection portion, and each extension portion is disposed in an inclined manner with respect to the connection portion, so that the cross-sectional shape of the main body 40 is substantially trapezoidal. The walking driving mechanism 20 is arranged in the connecting part, the screw 311 is arranged in the extending part, and the main body 40 can be matched with the shapes of the walking driving mechanism 20 and the transmission mechanism 30 and the requirements of the massage and wearing of a user.

In addition, referring to fig. 1 to fig. 3, fig. 8, and fig. 9, in the present embodiment, the main body 40 is provided with a guide rail groove 47, specifically, the guide rail groove 47 may be disposed on the first housing 43 and/or the second housing 44, the mounting bracket 13 is slidably connected to the guide rail groove 47, and the guide rail groove 47 is used for providing a guiding function to limit a moving direction and a moving range of the mounting bracket 13.

The massage mechanism 10 further includes a ball bearing 50, and the ball bearing 50 is connected to one end of the mounting bracket 13 and at least partially received in the rail groove 47. Since the ball bearings 50 are disposed between the mounting bracket 13 and the guide rail groove 47, the contact area between the mounting bracket 13 and the guide rail groove 47 is reduced, and the friction coefficient of the mounting bracket 13 during the movement is reduced, thereby reducing the frictional resistance, reducing the internal structure and energy loss, and prolonging the service life of the massager 100.

Referring to fig. 1, 8 and 9, in an embodiment of the present application, the main body 40 further includes a boss 48 disposed in the rail groove 47, the boss 48 extends in a direction parallel to the rail groove 47, and the ball bearing 50 abuts on a side of the boss 48 facing away from the bottom wall of the rail groove 47. Thus, the ball bearing 50 is directly abutted against the boss 48, so that the direct contact between the ball bearing 50 and the bottom of the guide rail groove 47 is avoided, the contact area between the ball bearing 50 and the guide rail groove 47 is reduced, and the friction force and the loss are further reduced.

In the present embodiment, the height of the side wall of the rail groove 47 is higher than the height of the boss 48 in the direction perpendicular to the extending direction of the rail groove 47. Therefore, when the mounting frame 13 moves, the movement of the bearing is always limited in the guide rail groove 47, the mounting frame 13 is prevented from being separated from the guide rail groove 47 in the moving process to influence the use of the massager 100, and the safety of the massager 100 in the using process is ensured.

It will be appreciated that the width of the boss 48 should be less than the diameter of the ball bearing 50, for example, the width of the boss 48 is 1/10-1/3 of the diameter of the ball bearing 50. Wherein, the diameter of the ball bearing 50 is 5 mm-20 mm, and the height of the boss 48 is 0.5 mm-3 mm. It will be understood that the width of the projection 48 is the length of the projection 48 in a direction perpendicular to the extension of the rail groove 47, and the height of the projection 48 is the distance between the top surface of the projection 48 facing away from the bottom wall of the rail groove 47 and the bottom wall of the rail groove 47.

Referring to fig. 8, in the present embodiment, two spaced bosses 48 are disposed in the guide rail groove 47, and the two bosses 48 are respectively located on two opposite sides of the bottom wall of the guide rail groove 47. Thus, the two spaced bosses 48 are symmetrically arranged to ensure uniformity of the bearing support force.

It can be understood that both ends of the ball bearing 50 are in contact with the bosses 48, thereby reducing the contact area of the ball bearing 50 with the guide rail groove 47, reducing the friction force, and prolonging the service life of the massager 100.

It is understood that the number of the bosses 48 may be other, for example, in other embodiments of the present application, the number of the bosses 48 may also be one, and the bosses 48 are disposed at the middle position of the rail groove 47, so that the bosses 48 may also reduce the contact area between the ball bearing 50 and the rail groove 47, and support the ball bearing 50, but not limited thereto.

As such, the contact area between the ball bearing 50 and the mounting body 131 is reduced, thereby reducing frictional resistance between the ball bearing 50 and the mounting body 131, and the wear of the mounting body 131 can be avoided.

It is understood that the restraint posts 134 are cylindrical.
