Document Type and Number:
WIPO Patent Application WO/2024/093868
Kind Code:
A1
Abstract:
An optical decorative film (10, 20, 30, 40, 50) for a vehicle, and an optical trim assembly for the interior of a vehicle. The optical decorative film (10, 20, 30, 40, 50) comprises a base layer (11, 21, 31, 41, 51), a texture structure (12, 22, 32, 42, 52), and a light condensing structure; at least a local area on the upper surface of the optical decorative film (10, 20, 30, 40, 50) is configured as a light condensing area, and light emitted by a backlight source located below the optical decorative film (10, 20, 30, 40, 50) passes through the light condensing structure, so that the light condensing area has increased light transmittance compared with the peripheral area of the light condensing area, so as to present different surface effects on the upper surface of the optical decorative film (10, 20, 30, 40, 50). By providing the texture structure (12, 22, 32, 42, 52) and the light condensing structure on the optical decorative film (10, 20, 30, 40, 50), the optical decorative film (10, 20, 30, 40, 50) presents different texture effects or decorative effects under external ambient light irradiation, the light transmittance of the optical decorative film (10, 20, 30, 40, 50) is improved under backlight conditions, and the brightness of the optical decorative film (10, 20, 30, 40, 50) is improved. When the optical decorative film (10, 20, 30, 40, 50) is applied to the optical trim assembly, by integrating functional components such as a backlight source (70), rich and varied optical effects are provided, and the attractiveness and comfort of the optical trim assembly during use are improved.
