Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive interior technology, and more specifically, relates to an automotive starry sky headliner and an automotive. Background Technology
[0002] As the automotive industry accelerates its evolution towards intelligence, electrification, lightweighting, and interactivity, automobiles have transformed from simple means of transportation into a "third living space" integrating mobility, intelligent interaction, and immersive experiences. Against this backdrop, the intelligent cockpit, as the core carrier of human-vehicle interaction, has become a focal point of industry competition due to its technological iteration and functional expansion. The automotive roof, as a crucial component of the intelligent cockpit, not only needs to meet basic requirements such as traditional structural support, sound and heat insulation, and lightweighting, but is also endowed with new functional missions including atmosphere creation, information interaction, and personalized experiences.
[0003] However, existing automotive roof technology still has significant limitations.
[0004] (1) Traditional ceilings generally use a pressing process of plastic fiberglass board substrate composite fabric layer, which can only achieve basic visual adjustment through changes in fabric texture or color. They cannot be linked with the in-vehicle intelligent system and are difficult to respond to the dynamic needs of users, such as driving mode switching, music rhythm, mood lighting, etc.
[0005] (2) Existing technologies rely on fabric layer printing or embroidery processes to achieve surface patterns, with fixed colors and textures, which cannot support programmable light effects or user-defined content (such as constellations, dynamic galaxies, etc.), which runs counter to the "personalized experience" pursued by young consumers.
[0006] (3) If the traditional ceiling needs to add ambient lighting, it is necessary to install LED light strips or optical fibers, which will result in thicker structure and increased weight. Furthermore, exposed optical fibers are prone to wear and tear, which conflicts with the trend of lightweighting in new energy vehicles.
[0007] In summary, traditional ceiling technology can no longer meet the evolving needs of smart cockpits for atmosphere creation, information interaction, and personalized experience, and an innovative ceiling solution is urgently needed. Utility Model Content
[0008] The purpose of this utility model is to provide a car starry sky roof and a car, which solves the problem that traditional roof technology cannot meet the needs of intelligent cockpits for atmosphere creation, information interaction and personalized experience.

[0010] Optionally, the substrate layer is a thermoformed PP fiberglass board.
[0011] Optionally, the diameter of the circular slot is 0.5 mm, and the bottom of the circular slot is 0.2 mm away from the lower surface of the substrate layer.

[0027] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0028] Example

[0030] Specifically, multiple optical fibers 3 generate dynamic light effects under the control of the optical engine box 4. These dynamic light effects, combined with the pattern on the surface decorative layer 2, can display a variety of rich shapes, greatly satisfying users' personalized needs, enhancing their driving experience, and improving passenger comfort. Furthermore, the optical fibers 3 are covered by a protective layer 5, protecting them from compression and wear, thus improving their durability.
[0031] In this embodiment, the dynamic lighting effect is achieved by controlling the color change of the light guide fiber 3 through the optical engine box 4. The surface decorative layer 2 is made of embroidered or non-embroidered fabric. The dynamic lighting effect simulates the starry sky, organically combining traditional Chinese embroidery with starry sky ambient lighting effects, creating a romantic atmosphere that allows passengers to experience the feeling of a starry sky close at hand. When the starry sky top is opened at night, the stars twinkle, just like the vast starry sea of summer nights in memory.
[0032] like Figure 3 and 4As shown, the optical engine box 4 can use existing products. The optical engine box 4 contains a controller and chip. Through the execution of the controller, the light source is displayed on the ceiling according to the control logic, forming shapes such as dynamic meteors, moons, or suns. In this embodiment, the optical engine box 4 includes: a lower housing 41, a heat sink 42, a circuit board 43, a connector mounting base 44, an upper housing 45, a quick-connect connector 46, and a side housing 47. The lower housing 41 serves as the basic support structure, integrating the mounting position for the heat sink 42, which is fixed to the heat sink 42 with two bolts.

[0035] Specifically, the bottom of the circular slot 11 is only 0.2mm from the lower surface, forming an ultra-thin light guide layer. At the same time, it prevents optical fibers from penetrating the surface decorative layer 2, keeping the ceiling surface flat.
[0036] Optionally, the protective layer 5 is made of carbon fiber cloth.
[0037] Specifically, carbon fiber cloth protects optical fibers from compression and wear, while also providing thermal insulation, which can significantly alter the aging rate of optical fibers and extend product lifespan.
[0038] Optionally, the other ends of the plurality of optical fibers 3 are connected to the optical housing 4 via quick-connect connectors 46.
[0039] Specifically, the optical fiber 3 is connected to the optical housing 4 via a quick-connect connector 46, replacing traditional welding or gluing. This facilitates maintenance or replacement and meets the needs of mass production and assembly.
[0040] Optionally, one end of the optical fiber 3 is fixedly connected to the substrate layer 1 by a high-temperature resistant adhesive.
[0041] Specifically, the optical fiber 3 is fixed with high-temperature resistant adhesive, which is suitable for the high-temperature exposure environment of the car roof and solves the problem of aging of traditional adhesives.
[0042] Optionally, multiple circular slots 11 are arranged in a dense array.
[0043] Specifically, the 11 circular slots are arranged in a dense array, which can form a variety of shapes and enhance the visual detail.
[0044] This embodiment also provides a car, including: The starry sky roof of the car in this embodiment.
[0045] Specifically, the car's starry sky roof can display a variety of rich designs, greatly satisfying users' personalized needs, enhancing the user's driving and riding experience, and helping to improve passenger comfort.
[0046] Optionally, the optical drive box 4 is connected to the vehicle body via a bracket. The specific structure of the bracket is not limited, as long as it can secure the optical drive box 4.
[0047] Optionally, the optical box 4 is electrically connected to the vehicle's BCM controller.
[0048] Specifically, the optical box 4 is electrically connected to the vehicle's BCM controller, allowing users to customize the starry sky effect through the vehicle's infotainment system and achieve dynamic interaction.
[0049] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
