[0062] When the present invention is in use, the decorative ring assembly 2 has three active surfaces, specifically surface A, surface B and surface C. Fig.13 It shows a schematic diagram of the structure of the decorative ring assembly 2 rotating to the A surface, Fig.14 It shows the structure diagram of the decorative ring assembly 2 rotating to the B surface, Fig.15 The schematic diagram of the structure of the decorative ring assembly 2 rotating to the C surface is shown.

[0063] When the decorative ring assembly 2 rotates to the A side, the active surface is entirely made of opaque plastic, and the light emitted by the light source module 11 cannot pass through. In actual product design, it can be defined as the state of the decorative ring assembly 2 in the vehicle locking mode, and the light source module 11 is extinguished accordingly.

[0064] When the decorative ring assembly 2 is rotated to the B side, the active surface consists of two parts, transparent plastic and opaque plastic. The light emitted by the light source module 11 can pass through the opaque plastic. In actual product design, brake lights, daytime running lights, reversing lights, turn signals, automatic driving lights, front position lights, rear position lights, etc. can be realized. When the brake lights, daytime running lights, reversing lights, turn signals, and automatic driving lights are realized, the light source module 11 needs to be controlled to be high-brightness, and when the front position lights and rear position lights are realized, the light source module 11 needs to be controlled to be low-brightness.

[0065] When the decorative ring assembly 2 is rotated to the C surface, the active surface consists of two parts, transparent plastic and opaque plastic. The light emitted by the light source module 11 can pass through the opaque plastic. In actual product design, brake lights, daytime running lights, reversing lights, turn signals, automatic driving lights, front position lights, rear position lights, etc. can be realized. When the brake lights, daytime running lights, reversing lights, turn signals, and automatic driving lights are realized, the light source module 11 needs to be controlled to be high-brightness, and when the front position lights and rear position lights are realized, the light source module 11 needs to be controlled to be low-brightness.

[0066] For example, the following designs can be performed for the bezel assembly 2 when it is rotated to the A surface, the B surface, and the C surface:

[0067] Locking mode: the decorative ring assembly 2 rotates to the A side, and the light source module 11 is turned off;

[0068] Driving mode 1: the bezel assembly 2 rotates to the B side, the white LED in the light source module 11 is highlighted, realizing the daytime running light function, the white light emitted by the light source module 11 illuminates the light guide bar 32, and the light is reflected to the B side by the pattern on the back of the light guide bar 32, and refracted into a corresponding light spot by the optical pattern on the B side;

[0069] Driving mode 2: the bezel assembly 2 rotates to the B side, the yellow LED in the light source module 11 is highlighted, realizing the turn signal function, the yellow light emitted by the light source module 11 illuminates the light guide bar 32, and the light is reflected to the B side by the pattern on the back of the light guide bar 32, and refracted into a corresponding light spot by the optical pattern on the B side;

[0070] Driving mode 3: the bezel assembly 2 rotates to the B side, the red LED in the light source module 11 is highlighted, realizing the brake light function, the red light emitted by the light source module 11 illuminates the light guide bar 32, and the light is reflected to the B side by the pattern on the back of the light guide bar 32, and refracted into a corresponding light spot by the optical pattern on the B side;

[0071] Driving mode 4: the bezel assembly 2 rotates to the B side, the red LED in the light source module 11 is at low brightness, realizing the functions of the front position light and the rear position light, the red light emitted by the light source module 11 illuminates the light guide bar 32, and the light is reflected to the B side by the pattern on the back of the light guide bar 32, and refracted into a corresponding light spot by the optical pattern on the B side;

[0072] Driving mode 5: the bezel assembly 2 rotates to the C surface, the white LED in the light source module 11 is highlighted, and the reversing light function is realized. The light spot of the reversing light is too different from that of other lights, and it is set on the C surface and not set together with other lights. The white light emitted by the light source module 11 illuminates the light guide strip 32, and the light is reflected to the C surface by the pattern on the back of the light guide strip 32, and refracted into a corresponding light spot through the optical pattern on the C surface.

[0073] It should be noted that the rotation of the bezel assembly 2 takes time. When there is a combination of a brake light and a rear position light, or a combination of a turn signal light, a front position light, and a rear position light, they can be placed on the same rotation plane, for example, on the B plane or the C plane.

[0074] Finally, it should be noted that the above examples are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. All variations that can be directly derived or associated with the content disclosed by a person skilled in the art should be considered as the protection scope of the present invention.
