A starry sky roller blind mechanism for a vehicle

By adopting a three-layer composite structure and an "S"-shaped path design in the starry sky roller blind mechanism, combined with a supporting keel and intelligent drive, the problem of fiber optic cable breakage has been solved, achieving flexible protection of the fiber optic cable and stable display of the starry sky effect, thus improving service life and visual experience.

AI Technical Summary

Technical Problem

In existing starry sky roller blind mechanisms, optical fibers or light sets are directly attached to the surface of the roller blind fabric. When rolling up, they are easily squeezed and rubbed, which can cause the optical fibers to break or the solder joints of the light sets to fall off, affecting the starry sky effect.

Method used

The fiber bundle runs through the three-layer structure of the roller blind (light-shielding base layer, buffer middle layer, and light-transmitting surface layer), with the output end flush with the light-transmitting surface layer. The buffer middle layer is designed with an "S" shaped path to avoid excessive stretching during winding. Combined with the supporting keel and intelligent drive mechanism, it ensures flexible protection and flat unfolding of the fiber.

Benefits of technology

It reduces the fiber breakage rate, improves the visual consistency and lifespan of the starry sky effect, enhances the wrinkle resistance of the roller blind fabric, and provides intelligent control and adaptive adjustment functions.

Abstract

The utility model discloses a kind of starry sky roller blind mechanism for car, comprising: main frame, fixed in sunroof roof interior, the main frame includes shell, slide rail and limit board;Roller blind cloth, roller blind cloth adopts three-layer composite structure, from inside to outside in turn is light-blocking base layer, buffer middle layer and light-transmitting surface layer;Optical fiber bundle, optical fiber bundle is in buffer middle layer in "S" shape path extension to avoid excessive stretch when winding up.Optical fiber bundle penetrates the three-layer structure of roller blind cloth, output end is flush with light-transmitting surface layer and is not outstanding, and the friction scratch when winding up is completely eliminated;Buffer middle layer in "S" shape path design, so that optical fiber can be along path slightly deformed when winding up stretch, avoid direct stress fracture, ensure that there is no extrusion when optical fiber winding, and optical fiber fracture rate is greatly reduced.
