[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 , Figure 2 As shown, in this example, the anti-fog rearview mirror base plate includes a body 1 and an insert 2. A mounting hole is formed in the middle of the body 1 to mate with the insert. A limiting shaft 9 is formed on the opposite sides of the end of the body 1. A retaining shaft 7 is installed at the other end of the body 1 and a handle 8 is installed on the retaining shaft 7. This is a common base plate configuration. When the base plate is assembled with the rearview mirror housing, the limiting shaft is used to be inserted into the retaining groove of the housing, and the handle protrudes out of the housing.

[0021] The insert is in the shape of a common cylindrical body. The insert 2 has a spherical surface 6 formed inside the cylindrical cavity to wrap the rotating body at the end of the rearview mirror support. During installation, the insert is directly embedded into the mounting hole.

[0022] In this example, the insert 2 has a radially protruding plate 3 at the top of the cylinder relative to the side position. The bottom surface of the plate 3 has an axially protruding foot 11. The body end face on the left and right sides of the mounting hole has an inwardly recessed groove 4. The top wall of the groove 4 adjacent to the mounting hole protrudes to form an eave 5. The insert is embedded in the mounting hole, and the foot and the eave are connected to each other simultaneously.

[0023] For the clamping leg, such as the L-shaped clamping leg 11, the longitudinal end of the clamping leg 11 is connected with the bottom surface of the convex plate, and the bottom surface of the transverse end of the clamping leg 11 is in the shape of an upwardly extending slope. During the embedding process, the end surface of the eaves abuts against the slope, and then the transverse end of the clamping leg is deformed to pass over the eaves. After passing over the eaves, the transverse end of the clamping leg is reset to hook the eaves to form a limiting position, thereby limiting the upward movement of the embedded part. The convex plate abuts against the hole opening end surface of the mounting hole to limit the downward movement, and the embedded part is stably arranged.

[0024] In addition, a ring groove can be formed at the peripheral wall of the embedded part 2 and extend circumferentially, and the elastic layer 10 can be arranged in the ring groove. The elastic layer is in the shape of a ring body, and the elastic layer is directly sleeved on the ring groove. In the normal state, the outer diameter of the elastic layer ring body is greater than the outer diameter of the middle cylinder of the embedded part. When the embedded part is arranged in the mounting hole, the elastic layer abuts against the hole wall to increase the frictional resistance. Of course, a plurality of ring grooves can be formed at the peripheral wall of the embedded part along the axial direction, such as the two ring grooves shown in the figure, which can further improve the stability.

Any technical solution falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the present application are also considered to be within the protection scope of the present application.​
