[0034] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0035] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0036] like Figure 1 , Figures 5 to 13 The sun visor rotation mechanism shown includes a mounting seat 3 and a hollow rotating shaft 2, a sun visor body connecting portion is provided on the mounting seat 3, the rotating shaft 2 includes a rotating shaft transverse section 202 pivotally connected to the mounting seat 3, the mounting seat 3 can rotate around the rotating shaft 2, a positioning block 5 is fixedly provided at the end of the rotating shaft transverse section 202, an end face of the positioning block 5 in the axial direction of the rotating shaft transverse section 202 is a first positioning face, a positioning portion is provided on the first positioning face, an end face of the mounting seat 3 in the axial direction of the rotating shaft transverse section 202 opposite to the first positioning face is a second positioning face, a positioning matching portion is provided on the second positioning face, the positioning portion and the positioning matching portion cooperate to position the mounting seat 3 after rotating around the rotating shaft transverse section 202, a sun visor fill light switch is provided between the positioning block 5 and the mounting seat 3, and the mounting seat 3 can disconnect and close the sun visor fill light switch by rotating around the rotating shaft transverse section 202.

[0037] By adopting the above-mentioned technical solution, the positioning part on the positioning block 5 and the positioning matching part on the mounting seat 3 constitute a rotational positioning structure, which can position the mounting seat 3 when the mounting seat 3 rotates around the transverse section 202 of the rotating shaft to a preset position, so that the sun visor body 4 connected to the mounting seat 3 can stop at the preset position, which helps to improve the user experience.

[0038] The sun visor fill light switch is integrated between the positioning block 5 and the mounting seat 3, and the sun visor fill light switch can be controlled to be disconnected and closed by rotating the sun visor, thereby controlling the opening and closing of the fill light, thereby enriching the functions of the sun visor rotation mechanism and improving the integration of the sun visor rotation mechanism. In addition, the makeup mirror cover on the sun visor can be removed, which is particularly suitable for some sun visors that are not provided with a makeup mirror cover.

[0039] The sun visor fill light switch is integrated between the positioning block 5 and the mounting seat 3. The hollow shaft 2 provides a channel for arranging the wiring harness. The end of the shaft transverse section 202 is the entrance and exit of the wiring harness, which can facilitate the connection between the sun visor fill light switch and the wiring harness. It has the characteristics of a high level of integration, and the smaller volume of the sun visor rotation mechanism can achieve more functions.

[0040] In some embodiments, Figure 5 and Figure 6 As shown, the positioning portion is a plurality of positioning grooves 502 provided on the first positioning surface, and the plurality of positioning grooves 502 are arranged at intervals in the circumferential direction of the rotating shaft transverse section 202. The plurality of positioning grooves 502 can correspond to a plurality of preset positions respectively, so that the mounting seat 3 can be positioned at a plurality of preset positions, and the mounting seat 3 can be positioned and switched between a plurality of preset positions, which helps to improve the user experience.

[0041] In some embodiments, Figure 8 As shown, the positioning matching portion is a positioning protrusion 304 provided on the second positioning surface. The positioning protrusion 304 matches the positioning groove 502. When the positioning protrusion 304 is inserted into the positioning groove 502, it can provide a force to prevent the mounting seat 3 from rotating around the horizontal section 202 of the rotating shaft. When the positioning protrusion 304 is separated from the positioning groove 502, the mounting seat 3 can rotate around the horizontal section 202 of the rotating shaft.

[0042] In some embodiments, the mounting seat 3 can slide axially relative to the shaft transverse section 202, and a spring 7 is provided between the mounting seat 3 and the shaft transverse section 202 to press the first positioning surface and the second positioning surface against each other. By providing the spring 7, the mounting seat 3 and the shaft 2 can press against each other in the transverse direction. The spring 7 can provide a preload force for the first positioning surface and the second positioning surface. When an external force drives the mounting seat 3 to overcome the preload force of the spring 7, the mounting seat 3 can slide axially along the shaft transverse section 202 to make the positioning protrusion 304 disengage from the positioning groove 502. When the mounting seat 3 rotates to a preset position and the external force applied to the mounting seat 3 is insufficient to overcome the preload force of the spring 7, the positioning protrusion 304 is inserted into the positioning groove 502.

[0043] In some embodiments, Figure 6 , Figure 7 and Fig.13As shown, the sun visor fill light switch includes a conductive clamp 6 installed on the positioning block 5 and an electrode 314 installed on the mounting seat 3. When the mounting seat 3 rotates to the first position around the horizontal section 202 of the rotating shaft, the conductive clamp 6 and the electrode 314 are connected. When the mounting seat 3 rotates to the second position around the horizontal section 202 of the rotating shaft, the conductive clamp 6 and the electrode 314 are disconnected. The conductive clamp 6 can be installed on the periphery of the positioning block 5, which can save lateral space and avoid affecting the positioning function of the positioning block 5. In a specific implementation, the conductive clamp 6 includes an arc portion 601, a limiting portion 603, and an extension portion 602 for contacting the electrode 314. An arc groove 503 is provided on the outer circumferential surface of the positioning block 5, the arc portion 601 is embedded in the arc groove 503, and the limiting portion 603 is embedded in the positioning groove 502, so as to connect the conductive clamp 6 to the positioning block 5. In a specific implementation, the electrode 314 can be embedded in the mounting seat body 301 by using an insert injection molding process.

The length of the pivoting portion 204 is longer than the length of the first matching hole, so that the mounting seat 3 can slide along the shaft transverse section 202.

[0048] As a specific example, the second positioning surface is arranged on the end surface of the pivot seat facing away from the spring 7, and the elastic force of the spring 7 causes the positioning block 5 to press against the pivot seat.
