Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more specifically, to a window glass structure and a vehicle having the same. Background Technology
[0002] With the increasing prevalence of intelligent driving, intelligent driving cameras place higher demands on the secondary image deviation value of the camera area on the windshield. This secondary deviation value is affected by glass curvature, mounting angle, and glass thickness. Glass curvature and mounting angle are often limited by the vehicle's design, meaning that the theoretical secondary image deviation value often fails to meet the camera's optical requirements. Current technologies using wedge-shaped films are extremely expensive, and for vehicles without HUD (Head-Up Display) requirements, using wedge-shaped films across the entire glass panel is prohibitively costly.
[0003] There is currently no effective solution to the aforementioned technical problems. Summary of the Invention
[0004] This application provides a window glass structure and a vehicle having the same, aiming to improve the high cost of adding an integral wedge diaphragm in the prior art.
[0005] According to one aspect of the embodiments of this application, a vehicle window glass structure is provided, including: a glass body, the glass body being laminated glass; and a tempered glass layer, wherein at least a portion of the glass body is bonded to the tempered glass layer via a functional film layer.
[0006] The embodiments of this application achieve the following technical effects: by additionally setting a reinforced glass layer and a functional film layer on the glass body, the reinforced glass layer is used to support the functional film layer, and at the same time, the functional film layer can make the reinforced glass layer and the glass body form a better fit; the glass body can be the windshield, side window glass, corner window glass or sunroof glass of a vehicle. When the glass body is the windshield, the functional film layer can be optionally set with a functional film, thereby enabling the glass body to meet the high requirements of the intelligent driving camera for optical performance and optimize the negative deviation of the window glass.
[0007] Furthermore, the functional diaphragm layer includes at least one of ordinary diaphragms, sound-insulating diaphragms, dimming diaphragms, and wedge-shaped diaphragms.
[0008] The embodiments of this application achieve the following technical effects: By selecting and using ordinary films, sound insulation films, dimming films and wedge films or a combination of the above films, the functional film layer can effectively and cost-effectively integrate multiple functions (such as dimming and sound insulation) into the car window glass, thereby enhancing the vehicle's technological feel and user experience.
[0009] Furthermore, the glass body has an area to be strengthened, and a reinforced glass layer covers the area to be strengthened, with the area covered by the reinforced glass layer being larger than the area of the area to be strengthened.
[0010] The above-described optional embodiments of this application achieve the following technical effects: by utilizing the high stiffness and strength of the reinforced glass layer, and its combination with the functional film layer, the local performance of the glass body is enhanced. This eliminates the need to cover the entire glass body with the reinforced glass layer and functional film layer; only a local area of the glass body needs to be covered for optimization, such as locally optimizing negative offset or locally optimizing dimming properties. This structural design allows for targeted improvements in the safety and functional performance of key areas without significantly increasing overall weight and cost.
[0011] Furthermore, the thickness of the reinforced glass layer is δ, where δ≤1.1mm.
[0012] The above-mentioned optional embodiments of this application achieve the following technical effects: the window glass structure meets performance requirements while achieving lightweighting, and the thinner glass layer reduces the overall amount used, which may ultimately reduce the overall cost; for applications requiring high transparency and low optical distortion, the ultra-thin glass layer can reduce interference with light, improve image quality and visual clarity, and at the same time, the thin design makes it easier to integrate the reinforced glass layer with other components (such as functional film layers) to achieve complex functional combinations and designs, thereby improving the overall driving experience for users.
[0013] Furthermore, the glass body includes: an outer glass layer; an inner glass layer, at least a portion of which is bonded to the tempered glass layer via a functional film layer; and an interlayer disposed between the outer glass layer and the inner glass layer.
[0014] The above-mentioned optional embodiments of this application achieve the following technical effects: the interlayer also has a accommodating space, and functional or ordinary diaphragms can be set in the accommodating space as needed to meet the user's personalized needs; at the same time, the composite glass body can significantly improve its safety performance and functionality without significantly increasing its weight.
[0015] Furthermore, the thickness of the outer glass layer is D2, the thickness of the inner glass layer is D3, and the thickness of the interlayer is D4, wherein D2+D3+D4≥4.36mm.
[0016] The above-mentioned optional embodiments of this application achieve the following technical effects: the thickness of the outer glass layer and the inner glass layer directly affects the strength and rigidity of the glass, while the thickness of the interlayer affects the realization of sound insulation and light-switching performance. Setting the thickness of both the outer glass layer and the inner glass layer to 1.8mm can ensure the strength of the glass body, so as to achieve lightweighting and cost saving while ensuring the strength of the glass.
[0017] Furthermore, the window glass structure also includes an injection molded part, which extends circumferentially along the glass body. One end of the injection molded part is connected to the glass body, and the other end of the injection molded part is connected to the vehicle body. The injection molded part is provided with at least one of the following: a buckle, an insert, and a bright strip.
[0018] The above-mentioned optional embodiments of this application achieve the following technical effects: by integrating injection-molded parts into the vehicle window glass structure, a stable connection between the vehicle window glass and the vehicle body can be achieved, while providing additional functionality, aesthetics, protection, and convenience. Through precision injection molding, it can be ensured that accessories such as buckles, bright strips, and inserts are perfectly integrated with the injection-molded parts, thereby forming a robust and sealed system with the glass body and the vehicle body.
[0019] Furthermore, the end face of the injection molded part that connects to the glass body is flush with it, or the end face of the injection molded part protrudes from the end face of the glass body.
[0020] The above-mentioned optional embodiments of this application achieve the following technical effects: the positional relationship between the injection molded part and the glass body directly affects the installation method and appearance of the car window glass. By adjusting the relative position of the injection molded part and the glass body, more flexible installation and design can be achieved, while making the appearance design more diversified.
[0021] Furthermore, the window glass structure also includes glass adhesive, one end of which is connected to the glass body and the other end of which is connected to the vehicle body. The glass adhesive is used to fix the glass body.
[0022] The above-mentioned optional embodiments of this application achieve the following technical effects: by using glass glue to fix the vehicle window glass structure, a stable connection between the vehicle window glass and the vehicle body can be ensured, while providing a good sealing effect, so that the vehicle window glass structure can maintain a good fixed state under various environments and conditions, thereby improving the safety and comfort of the vehicle.
[0023] According to another aspect of the embodiments of this application, a vehicle is provided, the vehicle including a window glass structure, the window glass structure being the aforementioned window glass structure.
[0024] The embodiments of this application achieve the following technical effects: while maintaining a lightweight design, the vehicle offers superior driving visibility, lower interior noise, and a higher level of technological sophistication and aesthetics. Application scenarios include intelligent driving vehicles, high-end models, MPVs, etc., and it is particularly suitable for vehicle designs requiring localized performance optimization and multi-functional integration.

[0041] Currently, with the popularization of intelligent driving, intelligent driving cameras are placing higher demands on the surface shape of the windshield camera area; at the same time, as users' perception of vehicle quality improves, their subjective pursuit of vehicle sound insulation performance and technological feel is also increasing. Traditional intelligent driving cameras are placing higher demands on the secondary deviation value of the windshield camera area; fixed glass is mostly injection molded integrally with PVC (Polyvinyl Chloride) / TPE (Thermoplastic Elastomer) material and glass body. In existing technologies, to improve secondary image deviation, the interlayer PVB (Polyvinyl Butyral film) in the windshield is typically replaced with a wedge-shaped PVB film for optical compensation. Strength requirements are met by increasing the glass thickness. Through process optimization, the thinnest laminated glass sheet is 1.8mm, with a total thickness of 4.36mm (1.8 + 0.76PVB + 1.8). However, due to the low yield rate of 1.8mm sheets, most commercially available glass sheets are 2.1mm thick, with a total thickness of 4.96mm.
[0042] (2.1 + 0.76PVB + 2.1). However, the following main problems exist:
[0043] 1) High cost of optical compensation: Using a whole wedge-shaped PVB film as an optical compensation solution is too expensive and not economical for non-high-end models.
[0044] 2) Heavy weight and cost issues: The use of laminated glass, especially the increased glass thickness to improve sound insulation, results in heavy glass and high cost. Furthermore, the yield rate issues in the manufacturing process further exacerbate the cost burden.
[0045] 3) Manufacturing difficulty and yield rate: Due to the limitations of PVC / TPE flowability, injection molding needs to be completed under a certain injection pressure. If the sound insulation performance of fixed glass is to be improved, a laminated glass solution needs to be adopted. The original glass sheet of the laminated solution is non-tempered glass, which is weak and easily breaks under high injection pressure. Moreover, when large-size fixed glass adopts the laminated solution, the manufacturing difficulty is high due to material limitations, resulting in a low yield rate and increased production costs.
[0046] 4) Functional integration and efficiency: Existing technologies cannot effectively and cost-effectively integrate multiple functions (such as sound insulation and dimming) into the car window glass, which limits the improvement of the car's technological feel.
[0047] Combination Figures 1 to 5 As shown, according to a specific embodiment of this application, a vehicle window glass structure is provided.
[0048] Specifically, the vehicle window glass structure includes a glass body 10 and a tempered glass layer 30, wherein the glass body 10 is laminated glass; at least a portion of the glass body 10 is bonded to the tempered glass layer 30 through a functional film layer 20.
[0049] Compared to the closest prior art, the technical effect is as follows: by additionally setting a reinforced glass layer 30 and a functional film layer 20 on the glass body 10, the reinforced glass layer 30 supports the functional film layer 20, and the functional film layer 20 enables the reinforced glass layer 30 to form a better fit with the glass body; the glass body 10 can be the windshield, side window glass, corner window glass or sunroof glass of a vehicle. When the glass body 10 is the windshield, the functional film layer 20 can be optionally equipped with a functional film, thereby enabling the glass body 10 to meet the high requirements of the intelligent driving camera for optical performance and optimize the negative deviation of the window glass.
[0050] Specifically, the functional diaphragm layer 20 includes at least one of a common diaphragm, a sound-insulating diaphragm, a dimming diaphragm, and a wedge-shaped diaphragm. By selecting and using common diaphragms, sound-insulating diaphragms, dimming diaphragms, and wedge-shaped diaphragms, or a combination of the above-mentioned diaphragms, the functional diaphragm layer 20 can effectively and cost-effectively integrate multiple functions (such as dimming and sound insulation) into the vehicle window glass, enhancing the vehicle's technological feel and user experience.
[0051] The above-mentioned optional embodiments of this application achieve the following technical effects: the functional diaphragm layer 20 selects sound insulation diaphragms, dimming diaphragms and wedge-shaped diaphragms or uses a combination of the above diaphragms, which can meet the user's pursuit of sound insulation and technological feel. Its application scenarios include, but are not limited to, the windshield of vehicles, the side windows and rear windows of high-end models, etc.
[0052] In one embodiment of this application, when the glass body 10 is a vehicle windshield, the functional diaphragm layer 20 may optionally use a wedge-shaped diaphragm in the combination. The use of the wedge-shaped diaphragm can meet the high requirements of the intelligent driving camera for optical performance and optimize the negative deviation of the window glass.
[0053] In another embodiment of this application, when the glass body 10 is a side window, corner window, sunroof, or other glass, the functional diaphragm layer 20 may optionally use a dimming diaphragm and a sound insulation diaphragm in combination to meet the user's needs for interior color tone and quiet environment.
[0054] In this embodiment, the sound-insulating diaphragm typically has a multi-layered structure, including damping materials such as PVB film, SGP (Safety Glass Polyester film), and EVA (Ethylene-Vinyl Acetatecopolymer film). These materials absorb sound waves during propagation, thereby reducing the intensity of sound transmission through the glass. Inside the vehicle, this significantly improves passenger comfort, especially at high speeds, effectively reducing wind and road noise and creating a quiet interior space. The dimming diaphragm can adjust the glass transparency according to needs or environmental conditions to provide stronger privacy or reduce glare. Examples include EC (Electrochromic) films and PDLC (Polymer Dispersed Liquid Crystal) films. Inside the vehicle, the dimming diaphragm can automatically or manually adjust the glass transparency to reduce glare.
[0055] In some embodiments of this application, the functional diaphragm layer 20 may also include a heat-insulating film, an anti-ultraviolet film, which can effectively block infrared and ultraviolet rays in solar radiation from entering the vehicle interior, reduce the temperature rise inside the vehicle, and protect the occupants and objects inside the vehicle from ultraviolet damage; and a decorative film, which is used to change the appearance of the glass (e.g., to provide different colors, patterns or textures) to meet the personalized needs of users.
[0056] Furthermore, the glass body 10 has a region 100 to be strengthened, and a reinforced glass layer 30 covers the region 100 to be strengthened, with the coverage area of the reinforced glass layer 30 being larger than the area of the region 100 to be strengthened. By covering the region 100 to be strengthened with the reinforced glass layer 30, and ensuring that the coverage area is larger than the region 100 to be strengthened, the strength and performance of this region can be significantly improved, while avoiding the glass breakage problem that may occur due to local stress concentration.
[0057] The above-described optional embodiments of this application achieve the following technical effects: by utilizing the high stiffness and strength of the reinforced glass layer 30 and its combination with the functional film layer 20, the local performance of the glass body 10 is enhanced. This eliminates the need to cover the entire glass body with the reinforced glass layer 30 and the functional film layer 20; only a local area of the glass body 10 needs to be covered. This allows for optimization of specific areas of the glass body 10, such as locally optimizing negative glass deviation or locally optimizing glass dimming properties. Such a structural design can achieve targeted improvements in the safety and functional performance of critical areas without significantly increasing overall weight and cost.
[0058] In one embodiment of this application, combined with Figure 4 As shown, only the part where the FOV (Field of View) of the intelligent driving camera intersects with the glass body 10 is set as the reinforcement area 100. A reinforced glass layer 30 and a functional film layer 20 are set in the reinforcement area 100. The functional film layer 20 is a wedge-shaped film. In this way, the wedge-shaped film only covers the reinforcement area 100, which can meet the requirements of optimizing the negative deviation of the glass and meet the optical requirements of the intelligent driving camera at low cost. The small wedge-shaped film area is the part where the camera FOV intersects with the glass, with an area of only about 0.01 square meters. Compared with the wedge-shaped film area used in the windshield in the prior art which is larger than 1 square meter, the cost of the wedge-shaped film can be greatly reduced.
[0059] It should be noted that there can be multiple areas 100 to be strengthened, as well as multiple tempered glass layers 30 and functional film layers 20. Each area 100 to be strengthened corresponds one-to-one with a tempered glass layer 30 and a functional film layer 20. Each area 100 to be strengthened forms an independent structural unit with the corresponding tempered glass layer 30 and functional film layer 20. These units are combined with the glass body 10 under high temperature and pressure conditions to form a composite glass structure with multiple performance optimization areas. This allows the vehicle window glass to provide customized performance enhancements according to the needs of different parts of the vehicle, such as simultaneously achieving sound insulation and light-diffusing functions on side windows. By setting tempered glass layers 30 and functional film layers 20 on multiple areas 100 to be strengthened respectively, performance optimization of multiple areas of the vehicle window glass can be achieved, such as simultaneously improving sound insulation and light-diffusing performance. This method can also be applied to vehicle windshields, side windows, rear windows, and corner windows.
[0060] In one exemplary embodiment of this application, the windshield of a vehicle can be configured with a region 100 to be enhanced according to the needs of multiple dimming areas. A dimming film is provided in the functional film layer 20 corresponding to the region 100 to be enhanced, so as to adjust the light intensity illuminating the driver and the occupants of the vehicle from different perspectives of the driver's position and the passenger's position, so as to avoid strong light or reflected light irritating the glasses. Since the driver and the intelligent driving camera are in different positions, the positions of the multiple regions 100 to be enhanced can be set locally only according to specific needs.
[0061] Furthermore, the thickness of the tempered glass layer 30 is δ, where δ ≤ 1.1 mm. The tempered glass layer 30 utilizes chemical tempering technology, allowing its thickness to be controlled below 1.1 mm while maintaining high strength and rigidity. This means that using ultra-thin tempered glass as the tempered glass layer 30 not only reduces the weight of the vehicle window glass but also lowers costs and improves production yield.
[0062] The above-mentioned optional embodiments of this application achieve the following technical effects: the window glass structure meets performance requirements while achieving lightweighting, and the thinner glass layer reduces the overall amount used, which may ultimately reduce the overall cost; for applications requiring high transparency and low optical distortion, the ultra-thin glass layer can reduce interference with light, improve image quality and visual clarity, and at the same time, the thin design makes it easier to integrate the reinforced glass layer with other components (such as the functional film layer 20) to achieve complex functional combinations and designs, thereby improving the overall driving experience for users.
[0063] In one exemplary embodiment of this application, the tempered glass layer 30 is made of ultra-thin chemically tempered glass with a thickness δ < 1.1 mm, which has a certain deformation capability. The ultra-thin chemically tempered glass is subjected to a high-temperature and high-pressure autoclave vacuum process with the functional film layer 20. At this time, the functional film layer 20 softens at high temperature, and the functional film layer 20 attached to the ultra-thin chemically tempered glass becomes a structure consistent with the surface of the glass body 10. At the same time, the softened functional film layer 20 can also make the ultra-thin chemically tempered glass and the surface of the glass body 10 fit tightly together, thereby enhancing the overall structural strength.
[0064] Furthermore, such as Figure 2As shown, the glass body 10 includes an outer glass layer 11, an inner glass layer 13, and a sandwich layer 12; at least a portion of the inner glass layer 13 is bonded to the tempered glass layer 30 via a functional membrane layer 20; the sandwich layer 12 is disposed between the outer glass layer 11 and the inner glass layer 13. The glass body 10 uses laminated tempered glass and can be configured with three or more layers. The outer glass layer 11 is located on the outermost side of the composite structure, directly facing the external environment and playing a major protective role. The inner glass layer 13 is located on the inner side of the composite structure, directly adjacent to passengers or the interior environment. The sandwich layer 12 is located between the outer glass layer 11 and the inner glass layer 13, and the sandwich layer 12 enhances the structural stability of the glass body 10.
[0065] The above-mentioned optional embodiments of this application achieve the following technical effects: the interlayer 12 also has a accommodating space, and functional or ordinary diaphragms can be set in the accommodating space as needed to meet the user's personalized needs; at the same time, the composite glass body 10 can significantly improve its safety performance and functionality without significantly increasing its weight.
[0066] It should be noted that dimming films or wedge-shaped films can also be integrated into the interlayer 12 as needed to meet the user's personalized requirements.
[0067] Furthermore, the thickness of the outer glass layer 11 is D2, the thickness of the inner glass layer 13 is D3, and the thickness of the interlayer 12 is D4, wherein D2+D3+D4≥4.36mm. The thicknesses D2 of the outer glass layer 11 and D3 of the inner glass layer 13 are both 1.8mm, while the thickness of the interlayer 12 can be set according to the thickness of its built-in film. For example, if a 0.76mm PVB film is used, then the thickness of the glass body 10 is D2+D3+D4=4.36mm. When other films (such as SGP, EVA film, PDLC) are installed in the interlayer 12, its thickness can also exceed 4.36mm.
[0068] The above-mentioned optional embodiments of this application achieve the following technical effects: the thickness of the outer glass layer 11 and the inner glass layer 13 directly affects the strength and rigidity of the glass, while the thickness of the interlayer 12 affects the realization of sound insulation and light-switching performance. Setting the thickness of both the outer glass layer 11 and the inner glass layer 13 to 1.8mm can ensure the strength of the glass body 10, so as to achieve lightweighting and cost saving while ensuring the strength of the glass.
[0069] Furthermore, such as Figures 1 to 3 , Figure 5As shown, the vehicle window glass structure also includes an injection-molded component 40, which extends circumferentially along the glass body 10. One end of the injection-molded component 40 is connected to the glass body 10, and the other end is connected to the vehicle body. The injection-molded component 40 incorporates at least one of the following: a clip, an insert, or a bright strip. The injection-molded component 40 is tightly bonded to the glass body 10 through the injection molding process, forming a single unit. It can serve as a connector to the vehicle body and integrate clips, inserts, bright strips, and other structures, enhancing the ease of installation and aesthetic design of the vehicle window glass.
[0070] It should be noted that the clips are mainly used for quick installation and removal of the glass body 10, simplifying the assembly process and improving production efficiency. The presence of the clips makes the installation of the car window glass more convenient, and also facilitates maintenance and replacement. The inserts are embedded in the metal or other material parts of the injection molded part 40 to enhance the stability and functional versatility of the injection molded part, such as improving sealing, tensile strength, or for subsequent assembly operations. The use of the inserts ensures that the injection molded part 40 can not only ensure the firm installation of the car window glass, but also improve the reliability and aesthetics of the overall structure. The bright strip, as a decorative component, can enhance the refinement of the car window appearance and increase the visual appeal of the vehicle. The bright strip not only plays an aesthetic role, but can also sometimes hide the gaps at the joints and improve waterproof and dustproof performance.
[0071] The above-mentioned optional embodiments of this application achieve the following technical effects: by integrating the injection-molded part 40 into the window glass structure, a stable connection between the window glass and the vehicle body can be achieved, while providing additional functionality, aesthetics, protection, and convenience. Through precision injection molding, it can be ensured that accessories such as buckles, bright strips, and inserts are perfectly integrated with the injection-molded part 40, thereby forming a robust and sealed system with the glass body 10 and the vehicle body.
[0072] In a preferred embodiment of this application, the injection molded part 40 is overmolded. Overmolded injection molded parts can provide a tighter seal, effectively preventing water, dust, and external noise from entering the vehicle interior, thus improving the vehicle's sound insulation performance and ride comfort. Through its elastic material, such as TPV (thermoplastic vulcanizate) or PVC (polyvinyl chloride), the overmolded injection molded part can absorb some of the impact force when the vehicle is involved in an accidental collision, reducing the risk of glass breakage and protecting passenger safety. Compared to metal or other materials, overmolded injection molded parts typically have a lower density, thereby reducing the overall weight of the window system. Simultaneously, overmolded injection molded parts can be designed in various shapes and colors to beautify the window edges, enhance the overall appearance of the vehicle, and make it more attractive and personalized.
[0073] Specifically, the end face of the injection molded part 40 that connects to the glass body 10 is flush with it, or the end face of the injection molded part 40 protrudes from the end face of the glass body 10. Depending on the specific vehicle model, the structure of the injection molded part 40 can be selected to accommodate the installation of various types of glass bodies 10, and it can also facilitate the integration of the injection molded part 40 with other accessories for vehicle decoration.
[0074] In one embodiment of this application, the end face of the injection molded part 40 is flush with the end face of the glass body 10, and the edge of the injection molded part 40 is kept on the same plane as the edge of the glass body 10, forming a smooth and seamless appearance. The flush setting not only makes the appearance cleaner and smoother, but also reduces noise and energy consumption during driving, and improves the stability and driving efficiency of the vehicle.
[0075] In another embodiment of this application, the end face of the injection molded part 40 protrudes beyond the end face of the glass body 10, extending beyond the edge of the glass body 10 to form a certain degree of protrusion. This configuration is mainly used in situations requiring enhanced sealing, stability, or additional functions of vehicle windows or glass structures. The protruding injection molded part can better contain and fix the glass body, providing additional mechanical support. Especially when the vehicle encounters a collision or extreme weather conditions, it can enhance the stability and safety of the glass. In addition, the protruding injection molded part can also be used to integrate functional components such as clips, inserts, or bright strips to achieve quick installation, removal, or aesthetic decoration of the vehicle window glass. Besides functional considerations, the design of the glass adhesive 50 also emphasizes coordination with the overall appearance of the vehicle. By selecting appropriate colors and shapes, it can be integrated into the design of the vehicle window without affecting or even enhancing the visual effect of the vehicle.
[0076] The above optional embodiments of this application achieve the following technical effects: the positional relationship between the injection molded part 40 and the glass body 10 directly affects the installation method and appearance of the car window glass. By adjusting the relative position of the injection molded part 40 and the glass body 10, more flexible installation and design can be achieved, while making the appearance design more diversified.
[0077] Furthermore, the window glass structure also includes glass adhesive 50. One end of the glass adhesive 50 is connected to the glass body 10, and the other end is connected to the vehicle body. The glass adhesive 50 is used to fix the glass body 10. After curing, the glass adhesive 50 forms a strong bonding layer that can withstand the vibration and impact during vehicle operation, while preventing the intrusion of external environmental factors, and has good adhesion and sealing properties. One end of the glass adhesive 50 is tightly bonded to the edge of the glass body 10, while the other end is firmly adhered to the corresponding installation position on the vehicle body. This end-to-end connection method not only ensures the physical stability between the glass and the vehicle body, but also ensures that the glass will not easily move or fall off when subjected to pressure, vibration, or impact.
[0078] The above-mentioned optional embodiments of this application achieve the following technical effects: by using glass glue 50 to fix the vehicle window glass structure, a stable connection between the vehicle window glass and the vehicle body can be ensured, while providing a good sealing effect, so that the vehicle window glass structure can maintain a good fixed state under various environments and conditions, thereby improving the safety and comfort of the vehicle.
[0079] According to another aspect of the embodiments of this application, a vehicle is provided, including the window glass structure of the above embodiments. Applying the window glass structure of the above embodiments to vehicle design, by optimizing the structure and performance of the window glass, can effectively address the high optical performance requirements of intelligent driving cameras, as well as users' pursuit of technological features such as sound insulation and dimming, thereby improving the user's driving experience.
[0080] The embodiments of this application achieve the following technical effects: while maintaining a lightweight design, the vehicle offers superior driving visibility, lower interior noise, and a higher level of technological sophistication and aesthetics. Application scenarios include intelligent driving vehicles, high-end models, MPVs, etc., and it is particularly suitable for vehicle designs requiring localized performance optimization and multi-functional integration.
[0081] As can be seen from the above description, the window glass structure in the above embodiments has the following beneficial effects: By introducing ultra-thin chemically tempered glass as the reinforced glass layer 30, not only is the strength and rigidity of the glass enhanced, but performance optimization in specific areas, such as sound insulation, dimming, or optical compensation, is also achieved, thereby improving the driving experience and safety; compared with traditional laminated glass, this structure significantly reduces weight, lowers costs, and improves production yield while maintaining the same or higher performance. Especially in the intelligent driving camera area, the use of small wedge-shaped films effectively solves the strict requirements of the camera on the deviation performance of the secondary image on the windshield, while significantly reducing the cost of the wedge-shaped film; in scenarios with high sound insulation performance requirements, this structure avoids the weight and cost problems caused by increasing the overall glass thickness, providing a more economical and efficient option for the automotive manufacturing industry. In addition, the integrated design of the injection-molded part 40 further enhances the multifunctionality and installation convenience of the window glass structure, and enhances the overall technological feel and aesthetics of the vehicle.
