Abstract
Description
Technical Field
[0001] This utility model relates to the field of iridescent starry sky film technology, specifically a PC interlayer iridescent starry sky film with light guide strips. Background Technology
[0002] With the booming development of the automotive industry and the increasing demands of consumers for vehicle quality, sunroofs have become a common feature in many car models. They not only increase interior lighting and improve ventilation, but also significantly influence the overall aesthetics and driving experience. Currently, people are no longer satisfied with sunroofs merely having basic functions; they increasingly expect them to offer unique and aesthetically pleasing decorative effects.
[0003] With its ability to display a dazzling and ever-changing visual effect reminiscent of a dreamlike starry sky under different lighting conditions and viewing angles, the iridescent starry sky film has become a highly promising automotive interior decoration material. However, currently, the application of iridescent starry sky film to car sunroofs is mostly done through post-application, where the film is simply attached to the already installed sunroof glass surface. This method has several drawbacks. Firstly, the application process is quite difficult, requiring professional skills and meticulous operation to minimize adhesion problems such as bubbles and wrinkles. Even then, it is difficult to guarantee an ideal fit between the film and the glass, which not only affects aesthetics but may also obstruct vision and reduce the driving experience. Secondly, during long-term use of the car, the edges of the post-application iridescent starry sky film are prone to peeling and flaking due to temperature fluctuations inside the car, vehicle vibrations, and external environmental factors. In severe cases, it may even detach completely, making it difficult to maintain its decorative effect and increasing subsequent maintenance costs. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a PC interlayer iridescent starry sky film with light guide strips, which addresses the shortcomings of the prior art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a PC interlayer iridescent starry sky film with light guide strips, including a printed cover layer, an EVA film layer one disposed at the bottom of the printed cover layer, a superconducting light PC film layer disposed at the bottom of the EVA film layer one, a pattern printed at the bottom of the superconducting light PC film layer, and an EVA film layer two disposed at the bottom of the pattern.
[0006] Preferably, light guide strips are provided on both the left and right sides of the superconducting PC film layer.
[0007] Preferably, the light guide strip is provided with an RGB light strip on its exterior.
[0008] Preferably, the outer wall of the RGB light strip is provided with a light-shielding strip.
[0009] Preferably, the thickness of the superconducting optical PC film layer is 0.175 mm.
[0010] Preferably, the thickness of both the first EVA film layer and the second EVA film layer is 0.76 mm.
[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects:
[0012] 1. This PC interlayer iridescent starry sky film with light guide strips, by pre-installing the iridescent starry sky film inside the car sunroof glass to form an integral whole with the glass, not only solves the problems of poor adhesion, poor durability, and impact on structural strength of existing retrofitted iridescent starry sky films, but also brings many beneficial effects such as improved aesthetic decoration, enhanced stability and safety, and optimized production and installation efficiency. It well meets consumers' needs for the aesthetics and safety of car interiors, conforms to the development direction of high-quality and efficient production in the automotive industry, and has important application value and practical significance.
[0013] 2. This PC interlayer RGB starry sky film with light guide strips can guide the light of the RGB light strips, making the patterns inside the superconducting PC film layer better displayed. By setting the light shielding strips, the light of the RGB light strips can be prevented from shining downwards and causing glare, and it also has a certain blocking effect, so that people inside the car cannot see the RGB light strips from inside the car, thus improving the aesthetics.
