[0044] Traditional automotive glass edging does not have any lighting effects. The glass is surrounded by simple black edging or edging with decorative strips, etc., without any luminous special effects, and cannot meet the diverse functional requirements of products.

[0045] See also Figure 1In a first aspect, this embodiment provides an edge wrapping assembly 1, comprising an edge wrapping member 11, a decorative layer 12, and a light guide layer 13. The edge wrapping member 11 is used to wrap around a vehicle window glass 2. The decorative layer 12 is disposed on the outside of the edge wrapping member 11. The light guide layer 13 is disposed between the decorative layer 12 and the edge wrapping member 11. The light guide layer 13 includes a light-emitting portion and a light guide portion disposed on the outside of the light-emitting portion. Light emitted by the light-emitting portion can be transmitted from the light guide portion and emitted through the decorative layer 12.

[0046] The material of the edging member 11 can be PU, PVC, or TPE. The edging member 11 is formed using an injection molding process. The shape of the edging member 11 is adapted to the shape of the vehicle window glass 2. The vehicle window glass 2 can be a front windshield, a side window, a corner window, a rear windshield, or a sunroof.

[0047] The decorative layer 12 provides both decorative and protective effects. The decorative layer 12 has a certain degree of transparency, allowing light to pass through. The decorative layer 12 can be colorless or colored. The decorative layer 12 can be placed on the exterior of a vehicle to enhance its appearance.

[0048] The light guide layer 13 is arranged between the decorative layer 12 and the edging piece 11, and the light guide layer 13 includes a light emitting portion and a light guiding portion. The number of the light emitting portion is at least one, such as a plurality of light emitting light sources. Specifically, the light emitting portion can be an LED lamp bead. The light guiding portion can refract, reflect and scatter to conduct light. Optionally, the light guide strip adopts optical grade transparent acrylic or PC material. The light emitting portion is arranged on the side of the light guiding portion, or on the surface of the light guiding portion facing the edging piece 11. The extension direction of the light guiding portion is the same as the extension direction of the edging piece 11.

[0049] Different from the existing technology, the above technical solution provides a light-guiding layer 13 on the edging member 11 and a decorative layer 12 outside the light-guiding layer 13, so that the edging has a light effect. It can not only serve as a warning to surrounding vehicles or pedestrians at night and increase the functional diversity of the car; it can also achieve a colorful and trendy appearance, making the car more technological and sporty.

[0050] In some embodiments, the light guide layer 13 and the decorative layer 12 are integrally formed. The light guide layer 13 and the decorative layer 12 are injection molded together. For example, the decorative layer 12 is injection molded onto the light guide layer 13, and then the light guide layer 13 with the decorative layer 12 is integrally injection molded with the window glass 2 and the edging member 11.

[0051] In some other embodiments, the light-guiding layer 13 includes a conductor circuit, which is electrically connected to the light-emitting portion and is used to connect to the vehicle power supply. Specifically, the conductor circuit can be a wiring harness or other conductive elements, which are used to connect the light-emitting portion and the vehicle power supply. When the car is driving or stopped, the on-board ECU controls the vehicle power supply to energize the light-emitting portion, and the light-emitting portion projects a light with an atmosphere effect to the periphery of the glass through the light-guiding portion. The light-emitting portion can use multiple light sources of different colors, such as LED light sources, and the conductor circuit can control the colors of multiple LED light sources to make the overall appearance of the product appear magical.

[0052] In some other embodiments, the decorative layer 12 is formed from a polyurethane injection molding material through an injection molding process. Polyurethane injection molding material has sufficiently low viscosity and high fluidity, resulting in low injection pressure, and can be applied as a surface layer to the surface of the edging member 11. The resulting decorative layer 12 exhibits a typical high gloss, brilliant 3D depth, and luxurious appearance. The decorative layer 12 itself is smooth and bright, creating a more beautiful visual effect, enhancing the vehicle's aesthetics and satisfying consumers' pursuit of high-quality, flawless appearance. Furthermore, the decorative layer 12 does not require additional polishing, reducing production costs and improving production efficiency.

[0053] In addition, polyurethane (PU) material has excellent properties, such as UV resistance, appropriate hardness, wear resistance, strong hardness, and not easy to be damaged. It also has self-healing properties. Once surface scratches occur due to careless use, the self-healing effect of PU can provide additional protection for the component surface, so that its surface always maintains a perfect appearance, the scratch resistance is greatly improved, and the light guide part can be protected.

[0054] Compared to existing metal bright trim strips, thicker edge pieces 11 are more susceptible to shrinkage and deformation, which can pull on the bright trim strip surface, causing optical distortion and affecting the product's aesthetics. This application, however, replaces traditional bright trim strips with a decorative layer 12. This layer has a certain degree of transparency and is self-healing. Combined with the ambient lighting effects of the light guide layer 13, this not only improves the product's aesthetics but also prevents optical distortion on the outer surface.

[0055] This embodiment utilizes a decorative layer 12, formed from a polyurethane injection molding process, on the edging member 11, facilitating production and eliminating the need for bright trim strips as used in related art. This reduces production costs and enhances product aesthetics. Furthermore, the decorative layer 12 possesses a high degree of hardness, overcoming shrinkage caused by the edging member 11 and enhancing the dimensional stability of the edging assembly 1. This effectively avoids surface optical distortion caused by the black bright trim strips and significantly improves the durability of the edging assembly 1.

[0056] In some other embodiments, a patterned film is provided outside the light guide layer 13. The patterned film is positioned between the decorative layer 12 and the light guide layer 13 and protected by the decorative layer 12. Specifically, the patterned film and light guide layer 13 are first integrally injection-molded, and then the decorative layer 12 is injection-molded onto the outer surface of the patterned light guide layer 13. Under illumination from the light-emitting portion, light is transmitted through the light guide layer 13 and the film, creating a patterned effect. Alternatively, the decorative layer 12 can be a thin, transparent PU protective layer.

[0057] In some other embodiments, along the stacking direction from the edging piece 11 to the decorative layer 12 , the thickness T of the decorative layer 12 satisfies the following condition: 0.2 mm ≤ T ≤ 2 mm.

[0058] For example, the thickness T of the decorative layer 12 can be 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, or 2 mm, etc. In this embodiment, by limiting the thickness of the decorative layer 12 to 0.2 mm-2 mm, the decorative layer 12 can be provided with a protective function while maintaining a light and thin appearance, thereby controlling the overall thickness of the edging member 11.

[0059] In some other embodiments, the hardness of the edging member 11 is less than the hardness of the decorative layer 12. Optionally, the hardness of the edging member 11 is 50A-95A. Optionally, the Shore hardness of the decorative layer 12 is 80D-60A. For example, the Shore hardness of the decorative layer 12 can be 80D, 100D, 20A, 30A, 40A, 50A, or 60A.

[0060] In some other embodiments, an electric functional element 14 is further included. The electric functional element 14 is disposed between the decorative layer 12 and the edging member 11 and is located on one side of the decorative layer 12. The electric functional element 14 is used to connect to an onboard power supply.

[0061] In some other embodiments, the electrical functional element 14 includes a carrier layer and an electrical functional layer, and the electrical functional layer is arranged on the surface of the carrier layer. The carrier layer is a carrier plate or a carrier film. The electrical functional layer is applied to the carrier film or the carrier plate. The carrier film or the carrier plate preferably contains a polymer, in particular polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyurethane (PU), polyethylene terephthalate (PET) or a combination thereof. The electrical functional layer can be an antenna or a circuit. Specifically, the antenna or the circuit is printed on the carrier layer, the carrier layer and the light guide layer 13 are integrally injection molded, and then the decorative layer 12 is injection molded on the light guide layer 13 with the carrier layer, and finally it is integrally injection molded with the edging piece 11 and the glass 2.

[0062] In some other embodiments, the edging member 11 includes a first edging portion 111 and a second edging portion 112 connected to the first edging portion 111, the first edging portion 111 is used to wrap the vehicle window glass 2, the second edging portion 112 is farther away from the vehicle window glass 2 than the first edging portion 111, the decorative layer 12 is arranged on one side of the second edging portion 112, and the second edging portion 112 is provided with at least one groove 113, and the groove 113 is used to accommodate part of the decorative layer 12.

[0063] A groove 113 is provided on the second edge portion 112, and the clamping force of the groove structure is used to strengthen the connection between the second edge portion 112 and the decorative layer 12, while reducing the flash. In addition, primer coating, polishing, etc. can also be used to strengthen the connection between the edge member 11 and the decorative layer 12.

[0064] In a second aspect, the present application provides a vehicle window assembly, comprising a vehicle window glass 2 and an edge wrapping assembly 1. The edge wrapping assembly 1 is the edge wrapping assembly 1 as described in the first aspect, and the edge wrapping assembly 1 covers the edge of the vehicle window glass 2.

[0065] The vehicle window glass 2 can be made of inorganic glass or organic glass. Inorganic glass materials such as soda-lime glass, aluminosilicate glass, borosilicate glass, alkali-free glass, and quartz glass can be used without particular limitation. Soda-lime glass is particularly preferred from the perspectives of manufacturing cost and formability. The glass forming method is not particularly limited. For example, in the case of inorganic glass, a glass sheet formed by a float process or the like is preferred.

[0066] When the glass is inorganic glass, the glass sheet can be either untempered or tempered. Untempered glass is obtained by shaping molten glass into a sheet and slowly cooling it. Tempered glass is obtained by forming a compressive stress layer on the surface of untempered glass. It can be air-cooled tempered glass or chemically strengthened glass.

[0067] When tempered glass is physically strengthened (e.g., air-cooled tempered glass), the temperature difference between the glass surface and the interior creates a compressive stress layer on the glass surface, strengthening the glass surface. When tempered glass is chemically strengthened, compressive stress can be generated on the glass surface after bending, using methods such as ion exchange, to strengthen the surface. Furthermore, glass sheets that absorb ultraviolet or infrared radiation can be used. While transparent glass sheets are preferred, tinted glass sheets are also acceptable without compromising transparency.

[0068] When the glass is composed of organic glass, examples of the material of the organic glass include transparent resins such as polycarbonate and acrylic resin (for example, polymethyl methacrylate).

[0069] In a third aspect, the present application provides a vehicle, comprising a vehicle body fitting and a vehicle window assembly as described in the third aspect, wherein the vehicle window assembly is connected to the vehicle body fitting. Specifically, the vehicle body fitting is a vehicle body sheet metal.

[0070] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
