Detailed Implementation

[0048] 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.

[0049] In view of this, in order to solve the above problems, please refer to the following: Figures 1-4 This embodiment provides an edge-sealing assembly 1, applied to a vehicle. The vehicle includes a window glass 2 and a body panel 3. The edge-sealing assembly 1 includes a first edge-sealing strip 11 and a second edge-sealing strip 12. The first edge-sealing strip 11 is made of a thermosetting material and is used to wrap the window glass 2, support the body panel 3, and overlap the body panel 3. The second edge-sealing strip 12 is connected to the first edge-sealing strip 11 and is made of a thermoplastic elastic material. The second edge-sealing strip 12 is used to wrap the window glass 2 and support the body panel 3.

[0050] The material of the first edge banding strip 11 is selected from thermosetting materials. Thermosetting materials refer to materials that, during processing, form a three-dimensional network structure through a chemical reaction, thereby losing their reversible plastic deformation ability. Once cured, the structure of thermosetting materials is irreversible and cannot be restored to a plastic state by heating or other means. Thermosetting materials can maintain good mechanical properties, chemical stability, and sealing performance in environments ranging from -60℃ to 200℃. Optionally, the thermosetting material is selected from thermosetting rubber materials. Optionally, the thermosetting material is selected from at least one of fluororubber (FKM), silicone rubber (VMQ), hydrogenated nitrile butadiene rubber (HNBR), acrylate rubber (ACM), ethylene propylene diene monomer (EPDM), and perfluoroether rubber (FFKM). The shape of the first edge banding strip 11 matches the shape of the window glass 2. Optionally, the first edge banding strip 11 is obtained by injection molding. The first edge banding strip 11 is used for overlapping and sealing with the body panel 3.

[0051] The material of the second edge banding strip 12 is selected from thermoplastic elastomers. Thermoplastic elastomers are a type of polymer material that combines the elasticity of rubber and the processability of plastics. At room temperature, thermoplastic elastomers exhibit elasticity and softness similar to vulcanized rubber. After heating, they can be melted and processed like thermoplastic plastics, allowing for repeated molding without vulcanization. They also have a short molding cycle, are recyclable, and produce no VOCs emissions, exhibiting good elasticity. Optionally, the thermoplastic elastomer is selected from at least one of styrene-based materials (TPS), olefin-based materials (TPV), polyurethane-based materials (TPU), polyester-based materials (TPE), polyamide-based materials (TPA), and vinyl chloride-based materials (TPVC). The shape of the second edge banding strip 12 matches the shape of the window glass 2. Optionally, the second edge banding strip 12 is obtained using an injection molding process.

[0052] In one embodiment, the thermosetting material is selected from EPDM, and the thermoplastic elastic material is selected from at least one of TPE and TPV.

[0053] Optionally, the window glass 2 can be a sunroof, windshield, rear windshield, side window, corner window, etc. Preferably, the window glass 2 is a sunroof.

[0054] Optionally, the first edge banding strip 11 includes a first support portion 111, a first wrapping portion 112, and an overlapping portion 113 connected to each other. The first support portion 111 is used to support the vehicle body panel 3, the first wrapping portion 112 is used to wrap the vehicle window glass 2, and the overlapping portion 113 is used to overlap the vehicle body panel 3.

[0055] Alternatively, the first wrapping portion 112 forms a first groove, and a portion of the window glass 2 is disposed within the first groove. Even more alternatively, the first wrapping portion 112 is adhesively connected to the window glass 2.

[0056] Optionally, a first support block 114 is provided between the first support portion 111 and the body panel 3. Even more optionally, the connection method between the first support block 114 and the first support portion 111, and the connection method between the first support block 114 and the body panel 3, can be adhesive connection, snap-fit ​​connection, threaded connection, etc., and this embodiment does not limit this.

[0057] Alternatively, the first support portion 111 may be embedded with a first support core 115; even more alternatively, the first support core 115 may be disposed corresponding to the first support block 114.

[0058] This embodiment improves the support capacity of the first support part 111 by setting the first support block 114 and / or the first support core 115, which is beneficial to improving the connection performance between the first support part 111 and the body panel 3, thereby reducing the risk of deformation and displacement of the first edge strip 11 and reducing the generation of abnormal noise.

[0059] Optionally, the second edge banding 12 includes a second support portion 121 and a second wrapping portion 122 connected to each other. The second support portion 121 is used to be installed on the vehicle body panel 3, and the second wrapping portion 122 is used to wrap the vehicle window glass 2.

[0060] Alternatively, the second wrapping portion 122 forms a second groove, and a portion of the window glass 2 is disposed within the second groove. Even more alternatively, the second wrapping portion 122 is adhesively connected to the window glass 2.

[0061] Optionally, a second support block 124 is provided between the second support portion 121 and the body panel 3. Even more optionally, the connection method between the second support block 124 and the second support portion 121, and the connection method between the second support block 124 and the body panel 3, can be adhesive connection, snap-fit ​​connection, threaded connection, etc., and this embodiment does not limit this.

[0062] Alternatively, the second support portion 121 may be embedded with a second support core 125; even more alternatively, the second support core 125 may be disposed corresponding to the second support block 124.

[0063] This embodiment improves the support capacity of the second support part 121 by setting the second support block 124 and / or the second support core 125, which is beneficial to improve the connection performance between the second support part 121 and the body panel 3, thereby reducing the risk of deformation and displacement of the second edge strip 12 and reducing the generation of abnormal noise.

[0064] Optionally, the second edge banding strip 12 further includes an extension 123, which is connected to the second wrapping part 122, and the extension 123 corresponds to and is spaced apart from the glass plate.

[0065] In this embodiment, by providing an extension 123 spaced apart from the glass plate, if the second edge strip 12 deforms or the glass plate shifts, the glass plate can abut against the extension 123, thus avoiding damage to the glass plate and preventing abnormal noise.

[0066] In summary, the edge-binding assembly 1 provided in this embodiment uses a first edge-binding strip 11 made of thermosetting material to overlap the body panel 3. This gives the first edge-binding strip 11 excellent weather resistance and temperature resistance, as well as elasticity and resistance to compression deformation. The first edge-binding strip 11 can tightly overlap with the body panel 3 in both normal and high-temperature environments, reducing the generation of abnormal noise. Furthermore, by using a second edge-binding strip 12 made of thermoplastic elastic material, the second edge-binding strip 12 has good shape retention and sufficient support. Therefore, the edge-binding assembly 1 provided in this embodiment can solve the problem of abnormal noise, reduce the overall cost, and also meet the requirements for maintaining special shaped cross-sections and provide sufficient support.

[0067] Please refer to this as well. Figures 1-4 In one embodiment, the extension direction of the first edge banding strip 11 is set at an angle to the extension direction of the second edge banding strip 12, and the edge banding component 1 further includes a corner joint 13, which connects the first edge banding strip 11 and the second edge banding strip 12.

[0068] Optionally, the angle between the extending direction of the first edge banding strip 11 and the extending direction of the second edge banding strip 12 is ≥90°, specifically, examples include 90°, 95°, 100°, 105°, 110°, 115°, or 120°, etc. Preferably, the angle between the extending direction of the first edge banding strip 11 and the extending direction of the second edge banding strip 12 is ≥110°.

[0069] The first edge banding strip 11 and the second edge banding strip 12 need to be connected and transitioned by the corner joint 13. Therefore, by limiting the angle between the extension direction of the first edge banding strip 11 and the extension direction of the second edge banding strip 12 to ≥90°, the overall reliability and aesthetics of the edge banding assembly 1 can be improved.

[0070] A corner joint 13 connects a first edge banding strip 11 and a second edge banding strip 12. The corner joint 13 is directly connected to the first edge banding strip 11, and the corner joint 13 is directly connected to the second edge banding strip 12. Optionally, the corner joint 13, the first edge banding strip 11, and the second edge banding strip 12 can be integrated into a single unit through injection molding.

[0071] The corner joint 13 satisfies the following conditions: when the ambient temperature is between 20℃ and 30℃, the connection strength between the corner joint 13 and the first edge banding strip 11 is ≥60N, and the connection strength between the corner joint 13 and the second edge banding strip 12 is ≥60N.

[0072] When the ambient temperature is ≥80℃ and the duration is ≥4h, the strength of the connection between the corner portion 13 and the first edge banding strip 11 is ≥5N, and the strength of the connection between the corner portion 13 and the second edge banding strip 12 is ≥5N.

[0073] When the ambient temperature is between 20℃ and 30℃, the edge-sealing assembly 1 is in a normal temperature environment. When the ambient temperature is ≥80℃, the edge-sealing assembly 1 is in a high-temperature environment.

[0074] When the ambient temperature is between 20℃ and 30℃, the strength at the connection between the corner portion 13 and the first edge banding strip 11 is ≥60N. Specifically, it can be 60N, 65N, 70N, 75N, 80N, 85N, 90N, 95N, or 100N, etc. Preferably, when the ambient temperature is between 20℃ and 30℃, the strength at the connection between the corner portion 13 and the first edge banding strip 11 is ≥90N.

[0075] When the ambient temperature is between 20℃ and 30℃, the strength at the connection between the corner joint 13 and the second edge banding strip 12 is ≥60N. Specifically, it can be 60N, 65N, 70N, 75N, 80N, 85N, 90N, 95N, or 100N, etc. Preferably, when the ambient temperature is between 20℃ and 30℃, the strength at the connection between the corner joint 13 and the second edge banding strip 12 is ≥90N.

[0076] When the ambient temperature is ≥80℃ and the duration is ≥4h, the strength at the connection between the corner portion 13 and the first edge banding strip 11 is ≥5N. Specifically, it can be 10N, 15N, 20N, 25N, 30N, 35N, or 40N, etc. Preferably, when the ambient temperature is ≥80℃ and the duration is ≥4h, the strength at the connection between the corner portion 13 and the first edge banding strip 11 is ≥15N.

[0077] When the ambient temperature is ≥80℃ and the duration is ≥4h, the strength at the connection between the corner joint 13 and the second edge banding 12 is ≥5N. Specifically, it can be 10N, 15N, 20N, 25N, 30N, 35N, or 40N, etc. Preferably, when the ambient temperature is ≥80℃ and the duration is ≥4h, the strength at the connection between the corner joint 13 and the second edge banding 12 is ≥15N.

[0078] The following describes the testing methods for the strength of joints:

[0079] Test Method 1: The ambient temperature is between 20℃ and 30℃. A 200mm long specimen containing the corner portion 13 is cut from the edge-sealing component 1. The corner portion 13 is located in the center of the specimen. The specimen is placed on a tensile testing machine and stretched at a speed of 200mm / min. The maximum force value at the time of fracture is measured.

[0080] Through test method one, it can be concluded that the edge-binding component 1 of this embodiment provides the following: when the ambient temperature is between 20℃ and 30℃, the connection strength between the corner portion 13 and the first edge-binding strip 11 is ≥60N, and the connection strength between the corner portion 13 and the second edge-binding strip 12 is ≥60N.

[0081] Test method two: Cut a 200mm long sample containing the corner part 13 from the edge-sealing component 1. The corner part 13 is located in the center of the sample. Place the sample in an oven at a temperature of 80±2℃ and hang a 0.5kg weight. Ensure that the corner does not break or crack after 4 hours.

[0082] Through test method two, it can be concluded that the edge-binding component 1 of this embodiment provides the following: when the ambient temperature is ≥80℃ and the duration is ≥4h, the connection strength between the corner portion 13 and the first edge-binding strip 11 is ≥5N, and the connection strength between the corner portion 13 and the second edge-binding strip 12 is ≥5N.

[0083] When the edge-sealing component 1 is used as the edge-sealing strip of the sunroof glass, it is usually necessary to maintain its assemblability under high temperature exposure. For example, the surface temperature can reach above 120°C in summer. However, the composite structure of traditional thermosetting materials and thermoplastic elastic materials is prone to interface cracking due to the difference in thermal expansion coefficients. Thermosetting materials are prone to hardening and embrittlement, while thermoplastic elastic materials are prone to softening and deformation.

[0084] Therefore, by providing a corner joint 13, this embodiment ensures that the strength of the connection between the corner joint 13 and the first edge banding strip 11, and the strength of the connection between the corner joint 13 and the second edge banding strip 12, meet the preset requirements in both normal and high temperature environments. This solves the problems of poor bonding force and complex processes between the first edge banding strip 11 and the second edge banding strip 12, which are made of different materials. As a result, the edge banding component 1 simultaneously possesses the processing performance of thermoplastic elastic materials and the weather resistance of thermosetting materials.

[0085] The following section provides a detailed description of the corner section 13:

[0086] In one embodiment, the corner portion 13 is made of the same material as the second edge banding strip 12.

[0087] In this embodiment, the corner joint 13 and the second edge banding strip 12 are made of the same material. Since the materials themselves have the same properties, the strength of the connection between the corner joint 13 and the second edge banding strip 12 meets the preset requirements in both normal temperature and high temperature environments.

[0088] Optionally, the material of the first edge banding strip 11 may also include vinyl silane grafting. By adding vinyl silane grafting to the thermosetting material, the compatibility between the thermosetting material and the thermoplastic elastic material is improved, thereby enhancing the connection performance between the first edge banding strip 11 and the second edge banding strip 12.

[0089] Optionally, the material of the second edge banding 12 is selected from TPE based on hydrogenated styrene-butadiene-styrene block copolymer (SEBS).

[0090] Optionally, the Shore A hardness of the second edge banding strip 12 is 60 to 90, specifically for example, 60, 65, 70, 75, 80, 85, or 90.

[0091] Optionally, the cross-sectional area of ​​the mold for the first edge banding strip 11 is 0.4% larger than the cross-sectional area of ​​the first edge banding strip 11.

[0092] Since the shrinkage rates of the first edge banding strip 11 and the second edge banding strip 12 are different, when the corner part 13 is made of the same material as the second edge banding strip 12, the difference in shrinkage rates between thermosetting materials and thermoplastic elastic materials can be resolved by adjusting the cross-sectional area of ​​the mold of the first edge banding strip 11, thereby achieving a consistent appearance and improving the aesthetics of the edge banding assembly 1.

[0093] Furthermore, the shrinkage rate of the corner portion 13 is typically between 1% and 1.8%, while the shrinkage rate of the first edge banding strip 11 is typically between 0.2% and 1%. The shrinkage rate of the first edge banding strip 11 is smaller and easier to control.

[0094] Please refer to this as well. Figures 1-12 In one embodiment, the first edge banding strip 11 includes a first support portion 111 for mounting on the body panel 3. The end of the first support portion 111 near the corner portion 13 is provided with a fixing portion. The fixing portion is used to connect the corner portion 13, and the part of the corner portion 13 used to connect the fixing portion is adapted to the shape of the fixing portion.

[0095] In one embodiment, the fixing part includes at least one of a fixing groove and a fixing protrusion 1115.

[0096] For example, the fixing part is a fixing groove. Another example is a fixing protrusion 1115. Yet another example is a fixing part that includes both a fixing groove and a fixing protrusion 1115.

[0097] Optionally, the connection method between the first edge banding strip 11 and the fixing part can be adhesive connection, snap connection, threaded connection, etc., and this embodiment does not limit this.

[0098] Therefore, this embodiment improves the connection performance between the corner joint 13 and the first edge banding strip 11 by providing a fixing part in the first support part 111 and adding mechanical interlocking in the structure, thereby improving the high temperature resistance of the connection between the corner joint 13 and the first edge banding strip 11 and ensuring that the strength of the connection between the corner joint 13 and the first edge banding strip 11 meets the preset requirements in the high temperature environment.

[0099] The following is a detailed description of the structure of the fixing part:

[0104] This embodiment provides multiple protruding teeth 1111a on the sidewall of the first sub-groove 1111 to disperse shrinkage stress and reduce the risk of interface cracking, thereby further improving the connection performance between the corner portion 13 and the first edge banding strip 11, further improving the high temperature resistance of the connection between the corner portion 13 and the first edge banding strip 11, and further ensuring that the strength of the connection between the corner portion 13 and the first edge banding strip 11 meets the preset requirements in a high temperature environment.

[0106] The second sub-slot 1112 includes a first part and a second part arranged sequentially along the arrangement direction from the opening of the second sub-slot 1112 to the bottom wall of the second sub-slot 1112, wherein the width of the first part is smaller than the width of the second part.

[0107] The second sub-slot 1112 can also be called a T-slot. Optionally, such as Figures 9-10 As shown, the opening width B1 of the second sub-groove 1112 is ≥2mm, the groove depth B2 of the second sub-groove 1112 is ≥4mm, the distance B3 between the second sub-groove 1112 and the side wall of the first support part 111 away from the overlapping part 113 is ≥2mm, the distance B4 between the second sub-groove 1112 and the first wrapping part 112 is ≥0.5mm, the bottom wall width of the second sub-groove 1112 is B5, B5-B1≥2mm, the groove depth of the first part is B6≥2mm, and the thickness T2 of the first support part 111 is ≥2.5mm.

[0108] Please refer to Figure 11 In another embodiment, the fixing part includes a fixing groove, which includes a plurality of third sub-grooves 1113, which penetrate the first edge banding strip 11 along the thickness direction of the first edge banding strip 11.

[0109] The plurality of third sub-grooves 1113 are arranged at intervals along the extension direction of the first edge banding strip 11, and the first edge banding strip 11 further includes a first wrapping part 112 for wrapping the window glass 2, and the distance from the bottom wall of the plurality of third sub-grooves 1113 to the first wrapping part 112 varies in a stepped manner.

[0110] Multiple third sub-slots 1113 form a multi-step transition zone, the width of which can be designed based on product requirements. Optionally, the number of third sub-slots 1113 is three to six. Optionally, such as Figure 11As shown, the distance C1 between the outermost third sub-groove 1113 and the side wall of the first support 111 facing the corner portion 13 is ≥2mm; the groove width C2 of the outermost third sub-groove 1113 is ≥2mm; the distance C3 between the outermost third sub-groove 1113 and the adjacent third sub-groove 1113 is ≥2mm; the groove width C4 of the other third sub-groove 1113 adjacent to the outermost third sub-groove 1113 is ≥2mm; the distance C5 between the outermost third sub-groove 1113 and the first wrapping portion 112 is ≥0.5mm; the groove depth C6 of the outermost third sub-groove 1113 is 2mm~4mm; the groove depth C7 of the other third sub-groove 1113 adjacent to the outermost third sub-groove 1113 is 2mm~4mm; and the thickness T3 of the first support 111 is ≥2.5mm.

[0111] Please refer to Figure 12 In another embodiment, the fixing part includes a fixing groove and a fixing protrusion 1115. The fixing groove includes a fourth sub-groove 1114, which penetrates the first edge banding 11 along the thickness direction of the first edge banding 11. The fixing protrusion 1115 is disposed on the surface of the first edge banding 11 facing the corner portion 13.

[0112] Furthermore, the fixing protrusion 1115 is provided with an inner groove 1116, which penetrates the fixing protrusion 1115 along the thickness direction of the first edge strip 11, and the opening direction of the inner groove 1116 is opposite to the opening direction of the fourth sub-groove 1114.

[0113] By setting a fourth sub-groove 1114 and an inner groove 1116 that are misaligned and have opposite openings, the connection performance between the corner portion 13 and the first edge banding strip 11 can be further improved, the high temperature resistance of the connection between the corner portion 13 and the first edge banding strip 11 can be further improved, and the strength of the connection between the corner portion 13 and the first edge banding strip 11 can be further ensured to meet the preset requirements in a high temperature environment.

[0114] Optionally, such as Figure 12 As shown, the distance D1 between the inner groove 1116 and the side wall of the fixed protrusion 1115 facing the corner portion 13 is ≥2mm, the groove width D2 of the inner groove 1116 is ≥2mm, the distance D3 between the fourth sub-groove 1114 and the side wall of the first support portion 111 facing the corner portion 13 is ≥2mm, the groove width D4 of the fourth sub-groove 1114 is ≥2mm, the groove depth D5 of the inner groove 1116 is 2mm~4mm, the distance D6 between the fourth sub-groove 1114 and the first wrapping portion 112 is ≥0.5mm, the groove depth D7 of the fourth sub-groove 1114 is 2mm~4mm, and the thickness T4 of the first support portion 111 is ≥2.5mm.

[0115] In one embodiment, the surface of the first edge strip 11 facing the corner portion 13 is provided with an interface transition layer, which is used to bond the corner portion 13.

[0116] The interface transition layer can enhance the interfacial adhesion strength. Optionally, the thickness of the interface transition layer is 0.05 mm to 0.1 mm. Optionally, the interface transition layer is obtained by applying a 94 primer.

[0117] This embodiment improves the bonding performance of the interface by setting an interface transition layer on the end face of the first edge banding strip 11, thereby further improving the connection performance between the corner portion 13 and the first edge banding strip 11, further improving the high temperature resistance of the connection between the corner portion 13 and the first edge banding strip 11, and further ensuring that the strength of the connection between the corner portion 13 and the first edge banding strip 11 meets the preset requirements in a high temperature environment.

[0118] Please refer to Figure 13 In one embodiment, the first edge banding strip 11 includes an overlap portion 113 for overlapping the vehicle body panel 3, and the first edge banding strip 11 satisfies the following formula: F=K×H×δ×sin(θ)≤1.5N / 100mm.

[0119] Wherein, F is the contact pressure between the overlapping portion 113 and the body panel 3 per 100mm, K is the cross-sectional width of the overlapping portion 113, the unit of K is m, H is the Shore hardness of the overlapping portion 113, H is a natural number, δ is the compression between the overlapping portion 113 and the body panel 3, the unit of δ is mm, and θ is the angle between the contact surfaces of the overlapping portion 113 and the body panel 3.

[0120] Specifically, the smaller the F value, the better. It has been verified that an F value ≤ 1.5N / 100mm can effectively improve abnormal noise.

[0121] The smaller the K value, the better. K is the average of the width K1 at the root of the overlap 113 and the width K2 at the middle of the overlap 113, K = (K1 + K2) / 2. Optionally, the K value satisfies 1mm ≤ K ≤ 2.5mm, for example, 1mm, 1.5mm, 2mm, or 2.5mm, etc.

[0122] The smaller the H value, the better. Optionally, the hardness H of the overlapping part 113 is Shore A, and H satisfies shore40≤H≤shore65. For example, it can be 40, 45, 50, 55, 60, or 65, etc.

[0123] Optionally, the compression amount δ satisfies 2mm≤δ≤4mm, specifically for example, 2mm, 2.5mm, 3mm, 3.5mm, or 4mm, etc.

[0124] The smaller the value of θ, the better. Optionally, the included angle θ satisfies 30°≤θ<90°. For example, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 85°, etc.

[0125] For example, K is 1mm, H is shore A 40, the compression amount δ is 2mm, the included angle θ is 30°, F=0.001*40*2*sin(30°)=0.04N, corresponding to 0.04N / 100mm.

[0126] Please refer to Figure 2 In one embodiment, the first edge banding strip 11 includes an overlap portion 113 for overlapping the body panel 3. The overlap portion 113 overlaps the surface of the body panel 3 and is provided with a first auxiliary layer 116. The first auxiliary layer 116 is used to separate the overlap portion 113 from the body panel 3.

[0127] The first auxiliary layer 116 can help reduce abnormal noise. Specifically, the first auxiliary layer 116 can reduce the effective contact area between the overlapping part 113 and the body panel 3, thereby reducing abnormal noise; or, the first auxiliary layer 116 can absorb noise, thereby reducing abnormal noise.

[0128] Therefore, this embodiment further reduces the generation of abnormal noise and improves the user experience by providing a first auxiliary layer 116 in the overlapping part 113.

[0129] And refer to Figures 1-4 In one embodiment, the first edge banding strip 11 extends along the length direction of the window glass 2, and the second edge banding strip 12 extends along the width direction of the window glass 2.

[0130] The edge-sealing assembly 1 includes two first edge-sealing strips 11 and two second edge-sealing strips 12. One first edge-sealing strip 11, one second edge-sealing strip 12, another first edge-sealing strip 11, and another second edge-sealing strip 12 are connected end to end to form a receiving cavity, and the vehicle window glass 2 is disposed in the receiving cavity.

[0131] In related technologies, the edge strip extending along the length of the window glass 2 is more likely to shift with the body panel 3, causing abnormal noise. However, in this embodiment, a first edge strip 11 made of thermosetting material is used to overlap the body panel 3, which gives the first edge strip 11 excellent weather resistance and temperature resistance, as well as elasticity and resistance to compression deformation. The first edge strip 11 can overlap tightly with the body panel 3 in both normal and high temperature environments, reducing the generation of abnormal noise.

[0132] A first edge banding strip 11, a second edge banding strip 12, another first edge banding strip 11, and another second edge banding strip 12 respectively wrap around the periphery of the vehicle window glass 2. Optionally, the vehicle window glass 2 is a sunroof glass, which is disposed within a receiving cavity. Optionally, the length of the first edge banding strip 11 is greater than the length of the second edge banding strip 12.

[0133] In one embodiment, the vehicle window glass 2 includes a first glass plate and a second glass plate, with the first glass plate disposed within the receiving cavity.

[0134] The second edge banding strip 12 includes an extension 123 that corresponds to and is spaced apart from the second glass plate. The side of the extension 123 facing the second glass plate is provided with a second auxiliary layer 126, which is used to separate the extension 123 from the second glass plate.

[0135] Optionally, the first glass panel is a sunroof and the second glass panel is a windshield; or, the first glass panel is a sunroof and the second glass panel is a rear windshield.

[0136] The second auxiliary layer 126 can help reduce abnormal noise. Specifically, the second auxiliary layer 126 can reduce the effective contact area between the second glass panel and the body panel 3, thereby reducing abnormal noise; or, the second auxiliary layer 126 can absorb noise, thereby reducing abnormal noise.

[0137] In this embodiment, by providing a second auxiliary layer 126 on the extension 123 spaced apart from the second glass plate, if the second edge strip 12 deforms or the glass plate is displaced, the glass plate can abut against the second auxiliary layer 126, which can not only avoid abnormal noise, but also avoid damage to the glass plate.

[0138] This application also provides a glass assembly, the glass assembly including a window glass and an edge-sealing component as described above, the edge-sealing component being disposed on the window glass.

[0139] This embodiment employs the edge-binding assembly provided in this application. The edge-binding assembly uses a first edge-binding strip made of thermosetting material to overlap the body panel, giving the first edge-binding strip excellent weather resistance and temperature resistance, as well as elasticity and resistance to compression deformation. The first edge-binding strip can tightly overlap with the body panel in both normal and high temperature environments, reducing the generation of abnormal noise. The edge-binding assembly also uses a second edge-binding strip made of thermoplastic elastic material, giving the second edge-binding strip good shape retention and sufficient support.

[0140] Therefore, the glass assembly provided in this application, by adopting the edge-wrapping components provided above, can not only solve the problem of abnormal noise, but also reduce the overall cost, while also ensuring the maintenance of special shape sections and providing sufficient support.

[0141] This application also provides a vehicle including a body and a glass assembly as described above, the glass assembly being disposed at an opening in the body.

[0142] Optionally, the window glass of the glass assembly serves as a sunroof, with the first edge strip overlapping the body panel on the side of the vehicle body, the second edge strip positioned near the windshield, and the second edge strip positioned near the rear windshield.

[0143] This embodiment employs the glass assembly provided in this application. The edging component of the glass assembly uses a first edging strip made of thermosetting material to overlap the body panel, giving the first edging strip excellent weather resistance and temperature resistance, as well as elasticity and resistance to compression deformation. The first edging strip can tightly overlap with the body panel in both normal and high temperature environments, reducing the generation of abnormal noise. The edging assembly also uses a second edging strip made of thermoplastic elastic material, giving the second edging strip good shape retention and sufficient support.
