[0026] In the manufacturing process of a car body, the roof sheet metal and side sheet metal are usually welded together. To allow the welding torch to reach them, a roof drainage channel is typically used. For overall vehicle styling, a decorative roof strip is installed within this drainage channel to conceal the weld points. With the development of the automotive industry, panoramic glass and large sunroofs have become increasingly common. To create a larger "skylight" effect, the roof strip within the drainage channel needs to be repainted. Current technology typically uses high-gloss black paint, which is not only costly but also environmentally unfriendly. Furthermore, current high-gloss black roof strips commonly exhibit defects such as orange peel texture and bubbling.
[0027] To address the aforementioned technical problems, this application provides a roof trim strip.
[0028] Reference Figure 1 As shown, this application embodiment provides a roof trim strip, which is installed in the roof drainage channel; the roof trim strip includes a trim strip body 100 and a high-gloss film 101. The cross-section of the trim strip body 100 is a U-shaped structure 102, and the high-gloss film 101 is attached to the outer surface of the U-shaped structure 102.
[0029] It should be noted that, in order to create a larger "skylight" effect, existing technologies require the roof trim strips within the traditional roof drainage channels to be recolored to ensure consistency with the roof glass, thereby enhancing the overall aesthetics and visual impact of the vehicle. However, existing high-gloss black paint solutions suffer from high costs, poor environmental performance, and cosmetic defects such as orange peel and bubbling.
[0030] The roof trim is installed within the roof drainage channel, primarily to conceal roof welds and for decorative purposes. Defects in the roof trim's appearance will diminish the interior's aesthetics and visual impact.
[0031] Reference Figure 1 As shown, the roof trim strip in this embodiment mainly includes a trim strip body 100 and a high-gloss film 101.
[0032] It should be noted that the trim body 100 is the basic structure of the roof trim and can be made of plastic or metal. It has a certain strength and flexibility and can adapt to the shape of the roof drainage channel. The cross-section of the trim body 100 is a U-shaped structure 102. The design of the U-shaped structure 102 can not only better fit the inner wall of the roof drainage channel, but also provide a flat surface for the subsequent high-gloss film 101.
[0033] It should be noted that the U-shaped structure 102 design has the following advantages:
[0034] Firstly, the U-shaped structure 102 has better fit: the U-shaped structure 102 can fit tightly against the inner wall of the roof drainage channel, ensuring that the trim strip will not loosen or fall off after installation, thus improving the stability of the trim strip.
[0035] Secondly, the U-shaped structure 102 enhances the sealing performance: the two sides of the U-shaped structure 102 can form a good seal with the inner wall of the roof drainage channel, preventing rainwater or other debris from entering the vehicle and enhancing the vehicle's waterproof performance.
[0036] Thirdly, the U-shaped structure 102 facilitates installation and removal: the design of the U-shaped structure 102 allows the trim strip to be easily inserted into the roof drainage channel, making installation convenient and quick. It also facilitates removal when maintenance or replacement is required.
[0037] It should be noted that the high-gloss film 101 in this embodiment is a thin film applied to the outer surface of the trim body 100, and has high gloss and good weather resistance. The use of the high-gloss film 101 replaces the traditional spray painting process, solves the appearance defects such as orange peel and bubbling that may occur during the spray painting process, and at the same time reduces production costs and reduces environmental impact.
[0038] The high-gloss film 101 of this application embodiment has the following advantages:
[0039] The high-gloss film 101 of this application embodiment has extremely high gloss, which can visually create an effect similar to black high-gloss paint, and avoids appearance defects such as orange peel and bubbling that may occur during the painting process.
[0040] In this embodiment, the surface of the high-gloss film 101 applied to the exterior of the trim body 100 is smooth and uniform, which can reflect light, enhance the visual effect of the roof, and create a greater sense of "skylight".
[0041] Compared to traditional painting processes, the use of high-gloss film 101 in this embodiment significantly reduces the emission of volatile organic compounds (VOCs), meeting the environmental protection requirements of modern automobile manufacturing. The production process of high-gloss film 101 is also cleaner, reducing environmental pollution.
[0042] It should be noted that the high-gloss film 101 also has excellent weather resistance, maintaining stable performance under various harsh climatic conditions. It can resist the effects of ultraviolet rays, temperature changes, humidity, and other factors, and is not prone to fading, yellowing, or aging, ensuring the long-term aesthetics of the trim.
[0043] Furthermore, the high-gloss film 101 is easy to process. In this embodiment, the high-gloss film 101 can be quickly attached to the outer surface of the trim strip body 100 via hot pressing, adhesive bonding, or other methods, resulting in simple operation and high production efficiency. In addition, the high-gloss film 101 can be customized to meet different design requirements for various vehicle models.
[0044] Compared to traditional high-gloss black paint, the roof trim provided in this application has the following advantages:
[0045] The first embodiment of this application can reduce costs: the use of high-gloss film 101 simplifies the production process, reduces the use of painting equipment and coatings, and lowers production costs. At the same time, high-gloss film 101 has a longer service life, reducing subsequent maintenance and replacement costs.
[0046] The second embodiment of this application can improve environmental friendliness: the production process of the high-gloss film 101 does not involve the use of harmful chemicals, reducing environmental pollution and meeting the environmental protection requirements in modern automobile manufacturing.
[0047] The third embodiment of this application can improve the appearance quality: the surface of the high-gloss film 101 is smooth and uniform, avoiding appearance defects such as orange peel and bubbling that may occur during the painting process, and improving the overall aesthetics of the trim.
[0048] The fourth embodiment of this application enhances durability: the high-gloss film 101 has excellent weather resistance and anti-aging properties, and can maintain stable performance under various harsh climatic conditions, thus extending the service life of the trim.
[0049] The roof trim strip of this application embodiment is applicable to various car models equipped with panoramic glass or large sunroofs, especially in models that pursue high-end and luxurious design, and can significantly enhance the visual effect of the roof. Specific application scenarios include: luxury sedans, SUVs, and MPVs.
[0050] Luxury sedans typically feature large panoramic sunroofs, and the high-gloss effect of the roof trim blends seamlessly with the roof glass, creating a more spacious and airy interior. SUVs and MPVs often have more complex roof designs; the high-gloss 101 design of the roof trim not only enhances the roof's aesthetics but also strengthens the overall quality of the vehicle.
[0051] Therefore, the roof trim provided in this application, through the combination design of the trim body 100 with a U-shaped structure 102 and a high-gloss film 101, successfully solves the problems of high cost, poor environmental performance, and appearance defects inherent in traditional black high-gloss paint solutions. The use of the high-gloss film 101 not only enhances the gloss and aesthetics of the trim but also strengthens its weather resistance and durability, meeting the environmental requirements of modern automobile manufacturing. The application of this roof trim will provide automakers with a more economical, environmentally friendly, and aesthetically pleasing solution, satisfying consumer demand for high-end, luxury models.
[0052] It should be noted that, in addition to being set to black, the color of the high-gloss film 101 can also be set to other colors according to the interior color scheme requirements. Those skilled in the art can make the selection as needed, and this application embodiment does not impose any special limitations on this.

[0056] As an optional implementation, the radius of the first fillet 106 is greater than 1.5 mm; and / or, the radius of the second fillet 107 is greater than 1.5 mm.
[0057] For example, the radius of the first fillet 106 is 2mm, and the radius of the second fillet 107 is 2mm.
[0058] For example, the radius of the first fillet 106 is 2.5 mm, and the radius of the second fillet 107 is 2.3 mm.
[0059] Wherein, the angle between the first sidewall 103 and the middle part 105 is greater than 80°, and / or, the angle between the second sidewall 104 and the middle part 105 is greater than 80°.
[0060] For example, the angle between the first sidewall 103 and the middle portion 105 is 85°, and the angle between the second sidewall 104 and the middle portion 105 is 85°.
[0061] For example, the angle between the first sidewall 103 and the middle portion 105 is 90°, and the angle between the second sidewall 104 and the middle portion 105 is 90°.
[0062] It should be noted that the specific data of the first fillet 106 and the second fillet 107 can be set by those skilled in the art as needed, and no special limitation is made thereto.
[0063] Reference Figure 2 As shown, as an optional implementation, the roof trim strip has lip structures 109 on both sides of its extension direction, and the lip structures 109 abut against the inner wall of the roof water channel.
[0064] In this embodiment, the lip structure 109 can abut against the inner wall of the roof drainage channel to form a good sealing structure, which can effectively prevent rainwater or other debris from entering the vehicle and enhance the vehicle's waterproof performance.
