[0002] Current automotive roof systems often have multiple configurations. To achieve a "sunroof-free" configuration, the sheet metal roof and roof need to be redesigned.

Detailed Implementation
[0054] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
[0055] In view of this, in order to solve the above problems, please refer to the following: Figures 1-2 This embodiment provides a vehicle window glass assembly 1, which includes a vehicle window glass 10 and an injection molding layer 20; the vehicle window glass 10 has a base coating area 11 at least provided in the edge region of the vehicle window glass 10, the base coating area 11 is used to apply a base coating; the injection molding layer 20 is provided on the surface of the vehicle window glass 10 coated with the base coating, and the injection molding layer 20 covers the vehicle window glass 10.
[0056] The window glass 10 can be used as a sunroof, corner window, side window, and rear windshield of a vehicle. Preferably, the window glass 10 is used as a sunroof of a vehicle.
[0057] The vehicle window glass 10 is either single-pane glass or laminated glass. If the vehicle window glass 10 is single-pane glass, the single-pane glass can be transparent glass or tinted glass. If the vehicle window glass 10 is laminated glass, the laminated glass includes an outer glass panel, an intermediate layer, and an inner glass panel that are stacked sequentially.
[0058] The outer and inner glass panels are made of transparent or tinted glass, with a thickness ranging from 0.7 mm to 4 mm. The visible light transmittance of both the outer and inner glass panels is ≥70%. For example, the outer glass panel can be 2.1 mm thick transparent glass with 89% visible light transmittance, and the inner glass panel can be 1.6 mm thick green glass with 83% visible light transmittance, or 2.1 mm thick green glass with 80% visible light transmittance.
[0059] The intermediate layer can be a thermoplastic polymer film. Optionally, the thermoplastic polymer film can be a transparent thermoplastic polymer film, a gray thermoplastic polymer film, a green thermoplastic polymer film, or a blue thermoplastic polymer film.
[0060] For example, the intermediate layer can be a single-layer or multi-layer structure. Examples of multi-layer structures include double-layer, triple-layer, quadruple-layer, and five-layer structures. The intermediate layer can also have other functions, such as adding infrared absorbers to provide sun protection or heat insulation, adding ultraviolet absorbers to provide ultraviolet protection, or having at least one layer of the multi-layer structure with a higher plasticizer content to provide sound insulation.
[0061] The primer coating area 11 is used to apply a primer coating. The primer coating enhances the adhesion of the injection molding material. When the primer coating is applied to the window glass 10, it forms a coating adhesion layer located in the primer coating area 11. Specifically, pre-applying a primer coating to the surface of the window glass 10 to be injection molded improves the adhesion of the injection molding material, thereby increasing the adhesion between the window glass 10 and the injection molding layer 20 and improving the bonding performance between the window glass 10 and the injection molding layer 20. The adhesion strength between the primer coating and the window glass 10, and between the primer coating and the injection molding layer 20, is superior to the adhesion strength between the window glass 10 and the injection molding layer 20.
[0062] The injection-molded layer 20 is prepared by injection molding. The injection-molded layer 20 is a single piece structure that covers the window glass 10. The injection-molded layer 20 can replace the roof 50, thereby reducing the cost of repeated design and development due to differences in sunroof configuration, while simplifying the production process and thus reducing production and inventory costs.
[0063] Optionally, the window glass 10 has an inner surface facing the vehicle interior and a side surface that bends to connect the inner surface, and an injection-molded layer 20 covers the inner surface of the window glass 10. Further optionally, the injection-molded layer 20 also covers the side surface of the window glass 10.
[0064] In one embodiment, the visible light transmittance of the injection-molded layer 20 is ≤1%, specifically, examples include 1%, 0.9%, 0.8%, 0.7%, 0.6%, 0.5%, 0.4%, 0.3%, 0.2%, 0.1%, or 0%. Preferably, the visible light transmittance of the injection-molded layer 20 is ≤0.5%, and more preferably, the visible light transmittance of the injection-molded layer 20 is ≤0.2%.
[0065] In summary, the window glass assembly 1 provided in this embodiment increases the adhesion between the window glass 10 and the injection molding layer 20 by providing a base coat area 11 for applying a base coat, thereby improving the connection performance between the window glass 10 and the injection molding layer 20. Furthermore, the base coat area 11 is limited to the edge area of the window glass 10, and the base coat is not applied to a whole sheet, so as to reduce the shrinkage stress between the window glass 10 and the injection molding layer 20, thereby reducing the risk of the window glass 10 breaking and improving the safety of the window glass assembly 1.
[0066] Please refer to this as well. Figures 1-6 In one embodiment, the base coat area 11 includes an edge base coat area 111 and a central base coat area 112; the edge base coat area 111 is disposed in at least one edge region of the window glass 10; the central base coat area 112 has a gap with at least a portion of the edge base coat area 111, and the central base coat area 112 is disposed in the central region of the window glass 10.
[0067] Both the edge primer area 111 and the central primer area 112 are coated with primer. The edge region of the window glass 10 is provided around the central region of the window glass 10. For example, the edge primer area 111 and the central primer area 112 are spaced apart. Or, for example, there is a gap between the edge primer area 111 and a portion of the central primer area 112, and the edge primer area 111 is connected to another portion of the central primer area 112.
[0068] If the base coat area 11 is only provided in the edge area of the window glass 10, there is a risk that the injection layer 20 in the central area of the window glass 10 will separate from the window glass 10, which may cause the injection layer 20 in the central area of the window glass 10 to fall when the window glass assembly 1 is actually installed on the vehicle.
[0069] Therefore, this embodiment further provides a central primer area 112, which cooperates with the edge primer area 111 to increase the adhesion between the window glass 10 and the injection-molded layer 20 located in the central region of the window glass 10, improve the connection performance between the window glass 10 and the injection-molded layer 20 located in the central region of the window glass 10, and avoid the separation of the window glass 10 and the injection-molded layer 20 located in the central region of the window glass 10; in addition, there is a gap between the central primer area 112 and at least part of the edge primer area 111, which can reduce the shrinkage stress between the window glass 10 and the injection-molded layer 20, thereby reducing the risk of the window glass 10 breaking and improving the safety of the window glass assembly 1.
[0070] Furthermore, the width of the edge primer area 111 is ≥20mm, specifically, it can be 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, or 50mm, etc. Additionally, the width of the edge primer area 111 can be determined according to the width of the body adhesive required by the user.
[0071] Furthermore, the edge region of the vehicle window glass 10 includes a left edge region located to the left of the central region, a right edge region located to the right of the central region, an upper edge region located above the central region, and a lower edge region located below the central region.
[0072] The edge base coating area 111 includes a left edge base coating sub-area 1114 located in the left edge region, a right edge base coating sub-area 1112 located in the right edge region, an upper edge base coating sub-area 1111 located in the upper edge region, and a lower edge base coating sub-area 1113 located in the lower edge region.
[0073] For example, the left edge base coat area 1114 is connected to the upper edge base coat area 1111, or the left edge base coat area 1114 and the upper edge base coat area 1111 are spaced apart.
[0074] For example, the left edge base coat area 1114 is connected to the lower edge base coat area 1113, or the left edge base coat area 1114 and the lower edge base coat area 1113 are spaced apart.
[0075] For example, the right edge base coat area 1112 is connected to the upper edge base coat area 1111, or the right edge base coat area 1112 and the upper edge base coat area 1111 are spaced apart.
[0076] For example, the right edge base coat area 1112 is connected to the lower edge base coat area 1113, or the right edge base coat area 1112 and the lower edge base coat area 1113 are spaced apart.
[0077] Furthermore, the upper edge base coat area 1111, the right edge base coat area 1112, the lower edge base coat area 1113, and the left edge base coat area 1114 are connected end to end in sequence.
[0078] The upper edge primer area 1111, the right edge primer area 1112, the lower edge primer area 1113, and the left edge primer area 1114 are connected to each other. It can also be understood that the edge primer area 111 is set around the edge area of the vehicle window glass 10.
[0079] This embodiment defines an annular edge base coating area 111 by sequentially connecting the upper edge base coating area 1111, the right edge base coating area 1112, the lower edge base coating area 1113, and the left edge base coating area 1114. This not only reduces the shrinkage stress between the window glass 10 and the injection molding layer 20, thus reducing the risk of the window glass 10 breaking, but also increases the contact area between the edge base coating area 111 and the window glass 10, thereby improving the connection performance between the window glass 10 and the injection molding layer 20.
[0080] The central base coat area 112 includes multiple base coat sub-areas, with at least two base coat sub-areas spaced apart.
[0081] The width H1 of the primer sub-area is 5mm to 20mm, specifically, for example, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, or 20mm. Preferably, the width H1 of the primer sub-area is 5mm to 15mm. More preferably, the width H1 of the primer sub-area is 10mm.
[0082] And / or, the width of the base coat sub-region is H1, and the distance between two adjacent base coat sub-regions is H2; wherein, the width H1: distance H2 is 1: (1~2), specifically, for example, 1:1, or 1:1.2, or 1:1.4, or 1:1.6, or 1:1.8, or 1:2, etc.

[0092] Optionally, the number of vertical base coat sub-areas 1123 can be 2 to 30, for example, 2, 4, 6, 8, 10, 12, 15, 20, 25, or 30, etc.
[0093] Optionally, one end of the vertical base coat sub-area 1123 is connected to the upper edge base coat sub-area 1111, and the other end is connected to the lower edge base coat sub-area 1113.

[0101] In summary, this embodiment optimizes the arrangement of the central primer area 112, such as an annular primer sub-area 1121, a horizontal primer sub-area 1122, a vertical primer sub-area 1123, and a block primer sub-area 1124. This allows the central primer area 112 to cooperate with the edge primer area 111, reducing shrinkage stress between the window glass 10 and the injection molding layer 20, thus reducing the risk of the window glass 10 breaking. Simultaneously, it increases the adhesion between the window glass 10 and the injection molding layer 20 located in the central region of the window glass 10, improving the connection performance between the window glass 10 and the injection molding layer 20 located in the central region of the window glass 10, and preventing separation between the window glass 10 and the injection molding layer 20 located in the central region of the window glass 10.
[0102] Please refer to Figure 7 In one embodiment, the window glass assembly 1 further includes an elastic buffer layer 30, which is disposed between the injection-molded layer 20 and the window glass 10.
[0103] Furthermore, the elastic buffer layer 30 is disposed in the central region of the window glass 10.
[0104] An elastic buffer layer 30 is disposed on one side of the window glass 10, and an injection-molded layer 20 covers the elastic buffer layer 30. Optionally, the material of the elastic buffer layer 30 is selected from flexible materials; more preferably, the material of the elastic buffer layer 30 is selected from at least one of silicone, flexible adhesive, and rubber.
[0105] For example, a primer is applied to the edge area of the window glass 10, an elastic buffer layer 30 is filled in the central area of the window glass 10, and then injection molding is performed to form an injection-molded layer 20 covering the elastic buffer layer 30 and the window glass 10.
[0106] Therefore, this embodiment provides an elastic buffer layer 30 to mitigate the shrinkage stress between the window glass 10 and the injection-molded layer 20, thereby further reducing the risk of the window glass 10 breaking and improving the safety of the window glass assembly 1. Furthermore, the elastic buffer layer 30 is located in the central area of the window glass 10, which helps to increase the contact area between the elastic buffer layer 30 and the window glass 10 and the injection-molded layer 20, thus improving the stress-absorbing effect of the elastic buffer layer 30.
[0107] Please refer to Figure 8 In one embodiment, the injection-molded layer 20 has a plurality of grooves 21 on the side opposite to the window glass 10, and the plurality of grooves 21 are spaced apart.
[0108] Furthermore, the plurality of grooves 21 are provided in the central region of the window glass 10.
[0109] Furthermore, along the arrangement direction from the bottom of the groove 21 to the opening of the groove 21, the width of the groove 21 gradually increases.
[0110] The groove 21 does not penetrate the injection-molded layer 20. Optionally, the grooves 21 are spaced apart along the width direction of the window glass 10, and / or, the grooves 21 are spaced apart along the length direction of the window glass 10. Optionally, the spacing between two adjacent grooves 21 is equal, or, at least partially, the spacing between two adjacent grooves 21 is not equal.
[0111] Therefore, by providing a groove 21 on the injection molding layer 20, the groove 21 can reserve shrinkage space, which helps to release the shrinkage stress between the window glass 10 and the injection molding layer 20, further reducing the risk of the window glass 10 breaking and further improving the safety of the window glass assembly 1.
[0112] Furthermore, multiple grooves 21 are provided in the central area of the window glass 10, which helps to increase the coverage area of the grooves 21 and improve the force release effect of the grooves 21.
[0113] Furthermore, by limiting the width of the groove 21, this embodiment makes the groove wall of the groove 21 be inclined, and the groove 21 has a trapezoidal structure with a wide opening and a narrow bottom, which is beneficial for the groove 21 to release stress.
[0114] Furthermore, the groove depth of the groove 21 is 1.5mm to 2.5mm, specifically, for example, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, or 2.5mm, etc. The groove depth of the groove 21 is as follows... Figure 8 As shown in W1.
[0115] And / or, the bottom width of the groove 21 is ≥5mm, specifically for example, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, or 15mm, etc. The bottom width of the groove 21 is as follows... Figure 8 As shown in W2.
[0116] And / or, the distance between the bottom wall of the groove 21 and the window glass 10 is ≥1mm, specifically, for example, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm, etc. The distance between the bottom wall of the groove 21 and the window glass 10 is as follows... Figure 8 As shown in W3.
[0117] If the gap between the bottom wall of the groove 21 and the window glass 10 is too small, the injection layer 20 will be too thin, resulting in insufficient injection material, material shortage, and exposure of the window glass 10.
[0118] And / or, the distance between two adjacent grooves 21 is less than 100 mm.
[0119] The spacing between two adjacent grooves 21 can be exemplified by, for example, 95mm, 90mm, 85mm, 80mm, 75mm, 70mm, 60mm, 50mm, 40mm, 30mm, 20mm, or 10mm, etc. Figure 8 As shown in W4.
[0120] This can also be understood as the injection layer 20 having at least one groove 21 every 100 mm along the width and / or length direction.
[0121] This embodiment ensures that the grooves 21 are uniformly provided in each area of the injection molding layer 20 by limiting the distance between adjacent grooves 21 to less than 100mm. This allows for the uniform release of shrinkage stress between the window glass 10 and the injection molding layer 20, further reducing the risk of window glass 10 breaking and further improving the safety of the window glass assembly 1.
[0122] Please refer to Figure 2In one embodiment, the surface of the injection-molded layer 20 facing away from the window glass 10 is the appearance surface 22, and the appearance surface 22 is provided with an appearance structure.
[0123] For example, the appearance structure can be created on the appearance surface 22 using an embossing technique. Optionally, a light-emitting element can be provided on one side of the appearance surface 22.
[0124] Preferably, the material of the injection layer 20 is selected from PU material, and the appearance structure includes a rough surface structure.
[0125] Since the exterior surface 22 comes into contact with the vehicle's interior environment, this embodiment improves its appearance by providing an exterior structure, creating a sense of atmosphere and enhancing the user experience. Furthermore, the atmosphere can be further enhanced by incorporating light-emitting elements for illumination.
[0126] Please refer to Figure 9 In one embodiment, the window glass assembly 1 further includes an adhesive layer 40 and an adhesive attachment, the adhesive layer 40 being disposed on the side of the injection-molded layer 20 opposite to the window glass 10, and the adhesive attachment being disposed on the adhesive layer 40.
[0127] The adhesive layer 40 bonds to the injection-molded layer 20. The adhesive layer 40 can also be used to bond to attachments. The attachments are located on the side of the adhesive layer 40 opposite to the injection-molded layer 20. Optionally, the attachments can be interior trim parts, mounting brackets, interior functional parts, etc.
[0128] The adhesive layer 40 can be obtained using adhesive materials such as adhesive glue or adhesive tape. Optionally, the adhesive layer 40 includes an adhesive sheet that covers the injection-molded layer 20. Optionally, the adhesive layer 40 includes a plurality of adhesive blocks arranged at intervals; further optionally, the plurality of adhesive blocks are arranged along the length direction of the window glass 10, and / or, the plurality of adhesive blocks are arranged along the width direction of the window glass 10.
[0129] Therefore, this embodiment provides a foundation for bonding accessories to be fixed to the injection molding layer 20 by setting the adhesive layer 40, thereby increasing the applicability of the window glass assembly 1.
[0130] Please refer to Figure 10 In one embodiment, the vehicle window glass 10 includes a first glass plate 12 and a second glass plate 13 spaced apart. The base coating area 11 is located at the edge area of the first glass plate 12 and the edge area of the second glass plate 13. The injection molding layer 20 covers the first glass plate 12 and the second glass plate 13 and also connects the first glass plate 12 and the second glass plate 13.
[0131] The injection-molded layer 20 can also serve as a connecting structure between the first glass panel 12 and the second glass panel 13, connecting the first glass panel 12 and the second glass panel 13. Furthermore, in this embodiment, the primer coating area 11 is defined as being located at the edge region of the first glass panel 12 and the second glass panel 13, and the primer coating is not applied to a whole sheet, in order to reduce the shrinkage stress between the injection-molded layer 20 of the first glass panel 12 and the second glass panel 13, thereby reducing the risk of breakage of the first glass panel 12 and the second glass panel 13 and improving the safety of the vehicle window glass assembly 1.
[0132] Please refer to Figure 11 In one embodiment, the window glass assembly 1 further includes a canopy 50, which is disposed on the side of the injection-molded layer 20 away from the window glass 10, and the canopy 50 shields the window glass 10.
[0133] To meet user needs, a canopy 50 can be added to one side of the injection-molded layer 20. Optionally, the canopy 50 can also cover the injection-molded layer 20. Optionally, the canopy 50 can be fixed to the injection-molded layer 20 by injection molding. Optionally, the canopy 50 can be bonded to the injection-molded layer 20.
[0134] Therefore, this embodiment provides a variety of window glass assemblies 1 by setting up a canopy 50, which can meet the needs of more users and improve the user experience.
[0135] This application also provides a method for manufacturing a vehicle window glass assembly, the method comprising:
[0136] S100 offers window glass and primer.
[0137] S200, the primer is applied to the edge area of the window glass.
[0138] S300, injection molding is performed on the surface of the window glass coated with the primer to form an injection-molded layer covering the window glass.
[0139] The method for preparing the vehicle window assembly provided in this application increases the adhesion between the vehicle window glass and the injection molding layer by applying a primer coating to the window glass, thereby improving the connection performance between the window glass and the injection molding layer. It also limits the application of the primer coating to the edge area of the window glass, rather than applying the primer coating to a whole sheet, in order to reduce the shrinkage stress between the window glass and the injection molding layer, thereby reducing the risk of window glass breakage and improving the safety of the vehicle window assembly.
[0140] This application also provides a vehicle, the vehicle including a body and a window glass assembly as described above, the window glass assembly being disposed on the body.
[0141] The vehicle provided in this application, by adopting the window glass assembly provided above, increases the adhesion between the window glass and the injection-molded layer by setting a base coat area, thereby improving the connection performance between the window glass and the injection-molded layer. Furthermore, the base coat area is limited to the edge area of the window glass, and the base coat is not applied to a whole sheet, so as to reduce the shrinkage stress between the window glass and the injection-molded layer, thereby reducing the risk of window glass breakage and improving the safety of the window glass assembly.
