[0049] Reference Figure 9 and Figure 10 Optionally, the rotating shaft 220 passes through the friction disk 230, and a spline 222 is provided on the rotating shaft 220, and the friction disk 230 is provided with a groove 234. The rotating shaft 220 and the friction disk 230 are engaged with the spline 222 and the groove 234, so that the rotating shaft 220 can drive the friction disk 230 to rotate. The rotating shaft 220 is provided with a slot 221, and the friction disk 230 is provided with a groove 233 on the side close to the rotating disk 300. A retaining spring 240 is clamped in the slot 221, and one side of the retaining spring 240 abuts against the groove 233, limiting the displacement of the rotating shaft 220 in the axial direction of the rotating shaft 220, preventing the rotating shaft 220 from separating from the friction disk 230 in the axial direction, and ensuring the engagement of the rotating shaft 220 and the friction disk 230.

[0050] Reference Figures 6 to 9Optionally, the friction disc 230 is provided with a plurality of first bevel teeth 231, which are arranged at intervals along the radial direction of the friction disc 230, and the rotary disc 300 is provided with a plurality of second bevel teeth 304, which are arranged at intervals along the radial direction of the rotary disc 300. The plurality of first bevel teeth 231 and the plurality of second bevel teeth 304 are staggered along the circumference of the rotary disc 300, and the first bevel teeth 231 and the second bevel teeth 304 are abutted so that the friction disc 230 can drive the rotary disc 300 to rotate.

[0051] The first beveled tooth 231 is provided with a first beveled surface 232, and the second beveled tooth 304 is provided with a second beveled surface 305. The first beveled surface 232 abuts against the second beveled surface 305. When the angle of the bracket 400 and the rearview mirror 500 is manually adjusted or the bracket 400 is rotated by an external force, since the first beveled tooth 231 is provided with the first beveled surface 232 and the second beveled surface 305 is provided, the first beveled surface 232 and the second beveled surface 305 can produce relative rotation, that is, the friction plate 230 and the turntable 300 can produce relative rotation, and the angle of the bracket 400 and the rearview mirror 500 can be manually adjusted, reducing the wear of the friction plate 230 and the turntable 300, and when the bracket 400 is impacted by other reasons, it can reduce the wear of the friction plate 230 and the turntable 300, thereby increasing the service life of the friction plate 230 and the turntable 300.

[0052] Optionally, two first inclined surfaces 232 are provided on the first bevel tooth 231, and the two first bevel surfaces 232 are symmetrically arranged along the radial direction of the friction disk 230. Two second bevel surfaces 305 are provided on the second bevel tooth 304, and the two second bevel surfaces 305 are symmetrically arranged along the radial direction of the turntable 300, so that when the angle of the bracket 400 and the rearview mirror 500 is manually adjusted or the bracket 400 is impacted, the turntable 300 and the friction disk 230 can rotate clockwise or counterclockwise relative to each other, and the rotation direction of the manually adjusted angle of the rearview mirror 500 is increased, so that when the bracket 400 is impacted by external forces in different directions, the friction disk 230 and the turntable 300 can rotate relative to each other, further reducing the wear between the turntable 300 and the friction disk 230.

[0053] Reference Figure 2 、 Figure 7 and Figure 8, an elastic component 110 is provided between the friction disc 230 and the base frame 100, and the elastic component 110 includes a spring 111 and a second gasket 112. The spring 111 and the second gasket 112 are passed through the rotating shaft 220. When the motor 210 drives the automatic adjustment of the angle of the rearview mirror 500, the elastic component 110 provides an axial elastic force to the friction disc 230, so that the first bevel teeth 231 of the friction disc 230 can abut against the second bevel teeth 304 of the turntable 300, so that the friction disc 230 can drive the turntable 300 to rotate. When the angle of the bracket 400 and the rearview mirror 500 is manually adjusted or the bracket 400 is impacted by other reasons, the first bevel teeth 231 originally abutting against the second bevel teeth 304 of the turntable 300 are abutted. The surface 232 and the second inclined surface 305 produce relative displacement, and the turntable 300 and the friction disk 230 rotate relative to each other. Since an elastic component 110 is provided between the friction disk 230 and the base frame 100, when the turntable 300 and the friction disk 230 rotate relative to each other, the friction disk 230 compresses the elastic component 110 in the axial direction, that is, the friction disk 230 can reciprocate in the axial direction to reduce the wear caused by the relative rotation of the friction disk 230 and the turntable 300, so as to realize manual adjustment of the angle of the bracket 400 and the rearview mirror 500, and when the bracket 400 is impacted by other reasons, it can protect the automatic adjustment device from being damaged, thereby improving the service life of the parts.

[0054] Optionally, the two ends of the spring 111 respectively abut the friction disc 230 and the base frame 100, so that the spring 111 provides axial damping to the friction disc 230. A second gasket 112 is provided between the spring 111 and the friction disc 230, and a second gasket 112 is provided between the spring 111 and the base frame 100. When the rotation angle of the rearview mirror 500 is electrically adjusted, that is, the rotating shaft 220 drives the friction disc 230 to rotate, and the friction disc 230 and the rotating disc 300 rotate relative to each other, the second gasket 112 can prevent the friction disc 230 from driving the rotation of the spring 111, thereby reducing the obstruction of the spring 111 to the rotation of the friction disc 230 and reducing noise. The second gasket 112 can reduce the wear between the spring 111 and the friction disc 230, as well as the wear between the spring 111 and the base frame 100, which is beneficial to improving the service life of the parts.

[0055] Optionally, the first gasket 102 and the second gasket 112 may be made of Teflon material, which has good wear resistance, low friction coefficient, good self-lubrication and other properties.

[0056] Optionally, the second gasket 112 can have a T-shaped cross-section in the axial direction, so that the spring 111 abuts against one side of the second gasket 112 and is sleeved on the raised portion of the second gasket 112, which is beneficial for preventing the spring 111 from being offset in the radial direction and is beneficial for positioning the spring 111 during installation. It can be obtained that no matter what the shape of the second gasket 112 is, the second gasket 112 can reduce the resistance between the friction disk 230 and the spring 111, prevent wear between the spring 111 and the friction disk 230 and the base frame 100, and reduce noise.

[0057] Reference Figure 2 and Figure 7 Optionally, the elastic component 110 is provided with an elastic cover 103 for preventing dust and protecting the elastic component 110. The elastic cover 103 can be deformed along the axial direction.

[0058] Reference Figure 2 and Figure 7 Optionally, a connecting bolt 120 is provided between the driving mechanism 200 and the turntable 300, one end of the connecting bolt 120 abuts the turntable 300, and the other end of the connecting bolt 120 is threadedly connected to the rotating shaft 220, and the connecting portion 401 of the connecting bolt 120 and the turntable 300 is cylindrical, so that when the angle of the rearview mirror 500 is manually or automatically adjusted, the connecting bolt 120 does not hinder the rotation of the turntable 300.

[0059] Reference Figure 2 and Figure 7 Optionally, a bearing 130 is provided between the connecting bolt 120 and the turntable 300 to make the rotation of the turntable 300 smoother.

[0060] Reference Figure 1 and Figure 2 Optionally, a mounting shell 105 is installed on the base frame 100 and a mounting cover 106 is installed on the turntable 300 . The mounting shell 105 is used to protect the base frame 100 , and the mounting cover 106 is used to protect the turntable 300 .
