Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a windshield and light-transmitting structure and a vehicle. Background Technology

[0002] In the field of vehicle technology, the red light pollution caused by the complexity of taillight design has always been a major concern. Especially in urban driving environments at night, due to the small distance between vehicles, the strong red light emitted by the taillights of the vehicle in front can easily cause glare and eye fatigue to drivers behind, thus significantly increasing driving safety risks.

[0003] To effectively improve the anti-glare problem of windshields, a novel anti-glare structure has been developed in related technical fields. This structure consists of multiple zones and sensors, all of which are arranged on the windshield and work together to form an adjustable transparency anti-glare system.

[0004] However, in practical applications, this anti-glare structure requires partitioning the entire windshield and equipping it with sensors for control, resulting in a complex structure and high production costs. While this design can reduce the risk of glare to some extent, it may also affect the driver's ability to see other objects outside the vehicle, thus limiting the actual effectiveness of the anti-glare system. Utility Model Content

[0005] The purpose of this application is to provide a windshield light-transmitting structure and vehicle, aiming to solve the problem of high cost of existing anti-glare structures. This windshield light-transmitting structure not only effectively reduces the risk of glare from the brake taillights of the vehicle in front, but also maintains the clarity of the forward view through the windshield, thereby ensuring driving safety. It eliminates the need for complex partitioning and sensor configurations, thus improving driving safety while reducing costs.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, embodiments of this application provide a windproof and light-transmitting structure, which includes a windproof and light-transmitting body and a light-filtering structure; the light-filtering structure is disposed on the windproof and light-transmitting body and is used to prevent red light from passing through the windproof and light-transmitting body.

[0008] A light-filtering structure is incorporated into the windshield's light-transmitting body, effectively blocking the red light emitted by the taillights of the vehicle ahead, thus preventing glare and eye fatigue for drivers behind due to red light. This light-filtering structure is simple and efficient in design, requiring no complex partitioning or sensor configuration, thereby significantly reducing production costs. Simultaneously, this windshield light-transmitting structure maintains a clear view of the road ahead through the windshield, allowing the driver to clearly observe the external environment and ensuring driving safety. Furthermore, the windshield light-transmitting structure of this application is easy to manufacture and install, suitable for various vehicle models, and has broad application prospects, effectively solving the problems of high cost and poor effectiveness of existing anti-glare structures.

[0009] In one possible implementation of the first aspect, the filter structure is a transparent body.

[0010] This embodiment, by designing the filter structure as a transparent body, ensures that while effectively blocking red light, it does not affect the normal transmission of other light rays, maintaining a clear field of vision. This design satisfies the need for anti-glare without affecting the driver's observation of the external environment, thus ensuring driving safety.

[0011] In one possible implementation of the first aspect, the filter structure is a red light absorption layer disposed on the windproof and light-transmitting body.

[0012] This embodiment achieves efficient absorption and blocking of red light by designing the filter structure as a red light absorption layer disposed within the windshield's light-transmitting body. This red light absorption layer is made of specific materials and possesses excellent red light absorption capabilities, effectively reducing the glare from the red light of the vehicle's taillights. Simultaneously, the red light absorption layer is tightly bonded to the windshield's light-transmitting body, ensuring structural stability and the durability of the filtering effect.

[0013] In one possible implementation of the first aspect, the windproof and light-transmitting body includes a multi-layered light-transmitting structure.

[0014] This embodiment enhances the stability and durability of the windshield by designing its translucent body as a multi-layered structure. The multi-layered design not only improves the overall strength of the windshield but also allows for flexible placement of filter structures between different layers, further optimizing the filtering effect. In specific configurations, each layer can be made of different materials or possess different optical properties to meet specific filtering requirements and safety standards. This design broadens the application range of windshield translucent structures, enabling them to better adapt to different vehicle models and driving environments, providing drivers with a safer and more comfortable driving experience.

[0015] In one possible implementation of the first aspect, the multilayer light-transmitting structure includes a first light-transmitting structure and a second light-transmitting structure, with a red light-absorbing layer located between the first light-transmitting structure and the second light-transmitting structure.

[0016] This embodiment fully utilizes the advantages of a multi-layer structure by placing the red light absorbing layer between the first and second light-transmitting layers. This not only enhances the structural stability but also ensures that the red light absorbing layer functions stably and efficiently. Red light is effectively blocked within this structure, further reducing driver glare and enhancing nighttime driving safety. Simultaneously, this design maintains structural simplicity, avoiding unnecessary complex components, thus controlling production costs while ensuring performance.

[0017] In one possible implementation of the first aspect, the windproof and light-transmitting body also includes an adhesive layer.

[0018] This embodiment enhances the bonding strength between the various light-transmitting structures by adding an adhesive layer to the windshield's light-transmitting body, making the entire windshield structure more stable and durable. The introduction of the adhesive layer not only improves the overall performance of the structure but also provides additional fixation and support for the red light-absorbing layer, preventing displacement or detachment during long-term use, thus ensuring the long-term stability of the light filtering effect. Simultaneously, the presence of the adhesive layer helps optimize light transmittance, reducing light reflection and scattering at the interlayer interfaces, further improving the driver's visual clarity and ensuring driving safety.

[0019] In one possible implementation of the first aspect, the adhesive layer is disposed between the first light-transmitting structure and the second light-transmitting structure.

[0020] This embodiment, by placing the adhesive layer between the first and second light-transmitting structures, not only strengthens the overall structure of the windshield's light-transmitting body but also ensures that the red light-absorbing layer is stably held in the middle, preventing any potential displacement or damage during driving. This design enhances the structure's durability while ensuring the consistently high performance of the red light-absorbing layer, continuously reducing the risk of glare to the driver caused by the red light from the taillights of the vehicle ahead. Furthermore, this design simplifies the manufacturing process, reduces reliance on precision components, thereby effectively controlling production costs while maintaining good light transmittance of the windshield, ensuring clear visibility for the driver and providing strong protection for nighttime driving safety.

[0021] In one possible implementation of the first aspect, the first light-transmitting structure is located on the side of the second light-transmitting structure facing the passenger compartment of the vehicle, and the red light absorbing layer is disposed between the first light-transmitting structure and the adhesive layer or between the second light-transmitting structure and the adhesive layer.

[0022] This embodiment places the first light-transmitting structure on the side facing the passenger compartment, which not only allows the driver to directly observe the road conditions ahead but also effectively blocks red light from the taillights of the vehicle in front, reducing the risk of glare. The position of the red light absorbing layer is flexible; it can be placed between the first light-transmitting structure and the adhesive layer, or between the second light-transmitting structure and the adhesive layer. Both arrangements ensure efficient absorption of red light while maintaining the overall light transmittance and visual clarity of the windshield structure. This design not only meets the practical needs of anti-glare but also takes into account structural stability and manufacturing economy, providing reliable protection for nighttime driving safety.

[0023] In one possible implementation of the first aspect, the thickness of the adhesive layer is 0.9 mm, the thickness of the first light-transmitting structure and the second light-transmitting structure is 2 mm, and the thickness of the red light absorbing layer is 0.1 mm.

[0024] This embodiment ensures that the windshield light-transmitting structure maintains excellent light filtering performance while also possessing good light transmittance and visual clarity by precisely controlling the thickness of each layer. The adhesive layer thickness is 0.9mm, ensuring sufficient bonding strength while avoiding light refraction problems caused by excessive thickness. The thickness of both the first and second light-transmitting layers is 2mm, a design that enhances structural stability while ensuring smooth light transmission. The red light absorption layer thickness is 0.1mm, ensuring efficient absorption of red light while minimizing its impact on overall light transmittance. By precisely controlling the thickness of each layer, the windshield light-transmitting structure of this application achieves a perfect balance between performance and cost, providing a solid technical guarantee for nighttime driving safety.

[0025] Secondly, some embodiments of this application provide a vehicle equipped with a windproof and light-transmitting structure, the vehicle including the windproof and light-transmitting structure as described in any of the above technical solutions.

[0026] Since the vehicle provided in this application embodiment includes the windproof and light-transmitting structure as described in any of the above technical solutions, both can solve the same technical problem and achieve the same technical effect, so they will not be described again.

[0036] In the embodiments of this application, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," and "third" may explicitly or implicitly include one or more of that feature.

[0037] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0038] In a first aspect, this application provides a windproof and light-transmitting structure 100, which includes a windproof and light-transmitting body 10 and a light-filtering structure 20; the light-filtering structure 20 is disposed on the windproof and light-transmitting body 10 and is used to prevent red light from passing through the windproof and light-transmitting body 10.

[0039] Please see Figure 1 , Figure 1This is a schematic diagram of the overall structure of the windshield light-transmitting structure 100 provided in some embodiments of this application. In this embodiment, the windshield light-transmitting body 10, which has basic light-transmitting function, is combined with a filter structure 20 that can block red light from passing through. The filter structure 20 is stably set on the windshield light-transmitting body 10 to directly filter the incident red light. The windshield light-transmitting body 10 is the basic structure of the vehicle windshield, providing light transmission and visibility protection. The filter structure 20 is a functional layer made of special materials. The two work together. Compared with the anti-glare structure in the prior art that relies on complex partitions and sensors, this solution effectively reduces the risk of glare to the driver behind the vehicle caused by the taillights of the vehicle in front, while ensuring clear visibility, and significantly improving driving safety and economy with a simpler structural design and lower cost.

[0040] For example, the light-filtering structure 20 is securely mounted on the windproof and light-transmitting body 10 by spraying. This not only simplifies the manufacturing process but also facilitates the uniform distribution of the light-filtering structure 20, further improving the filtering effect. Simultaneously, the spraying method can adapt to windproof and light-transmitting bodies 10 of different shapes and sizes, improving the versatility and flexibility of the windproof and light-transmitting structure 100.

[0041] For example, the filter material is a rare earth resin, whose main components are rare earth elements (such as Sm). 3+ The components include polymer matrices (such as methacrylic acid and styrene copolymer resin) and functional additives. Rare earth elements in rare earth resins possess unique electronic structures and optical properties, exhibiting strong absorption capabilities in the red light band. When rare earth resin is used as the filter structure 20, it selectively absorbs the red light emitted by the taillights of the vehicle ahead, while having minimal impact on other visible light bands, thus effectively reducing glare while ensuring clear driver visibility. Furthermore, rare earth resin materials possess excellent weather resistance and stability, adapting to various complex and changing driving environments, ensuring the long-term effectiveness of the filter structure 20. Simultaneously, the preparation process of rare earth resins is relatively mature and cost-controllable, which helps reduce the overall production cost of the windshield light-transmitting structure 100 and enhances its market competitiveness.

[0042] For example, in the specific implementation of this embodiment, the windproof and light-transmitting body 10 can be cleaned first to remove oil and impurities from the surface, then rare earth resin filter material can be sprayed on it, and then cured through drying and other process steps to finally form a stable and reliable filter structure 20.

[0043] This embodiment effectively blocks the red light emitted by the taillights of the vehicle ahead by setting a light-filtering structure 20 on the windshield light-transmitting body 10, avoiding glare and eye fatigue for drivers behind due to red light. The design of this light-filtering structure 20 is simple and efficient, requiring no complex partitioning or sensor configuration, thus significantly reducing production costs. Simultaneously, the windshield light-transmitting structure 100 maintains the clarity of the view in front of the windshield, allowing the driver to clearly observe the external environment and ensuring driving safety. Furthermore, the windshield light-transmitting structure 100 of this application has the advantages of ease of manufacture and installation, is suitable for various vehicle models, has broad application prospects, and effectively solves the problems of high cost and poor effectiveness of existing anti-glare structures.

[0044] In the above embodiments, regardless of the specific materials or processes used, as long as the anti-glare effect is achieved through the combination of the two, it falls within the scope of protection.

[0045] In some embodiments, the filter structure 20 is transparent.

[0046] In this embodiment, the transparent filter structure 20 is a functional component designed based on optical principles. It utilizes the selective absorption or reflection characteristics of materials for specific wavelengths (red light) to accurately filter red light while maintaining the transparent appearance of the windshield, thus preventing the red light from the taillights of the vehicle in front from dazzling the driver. Compared with the anti-glare structures in the prior art that rely on complex partitions and sensors, this solution significantly reduces production costs with the simple design of the transparent body, while ensuring clear vision and effectively improving driving safety. It successfully solves the problems of high cost and limited vision in the prior art.

[0047] Of course, in other embodiments, the filter structure 20 can also take other forms, such as filters or filter films. These forms of filter structures 20 also have the ability to effectively block red light and can be flexibly designed and adjusted according to specific needs. For example, filters can achieve precise filtering of the red light band through specific optical design, while maintaining good transmittance of other visible light bands. Filter films, on the other hand, can utilize their thin and transparent properties to adhere tightly to the windshield light-transmitting body 10, providing a stable and durable filtering effect. These different forms of filter structures 20 can all provide the driver with a clearer and more comfortable visual experience while ensuring driving safety.

[0048] Please see Figure 2 , Figure 3 and Figure 4 , Figure 2 for Figure 1 The front view of the windbreak and light-transmitting structure shown is shown. Figure 3 for Figure 1 The top view of the windproof and light-transmitting structure shown. Figure 4 for Figure 2 The diagram shows a cross-sectional view of the windproof and light-transmitting structure. In some embodiments, the light-filtering structure 20 is a red light-absorbing layer 1 disposed on the windproof and light-transmitting body 10.

[0049] In this embodiment, the red light absorption layer 1 is a functional structure designed based on the principle of optical absorption. Its internal material molecules or crystal structure can resonate with red light photons and convert red light energy into heat energy or other forms of energy. While maintaining the windshield's good transmittance to other visible light, it efficiently filters the red light from the taillights of the vehicle in front, avoiding glare for the driver. Compared with the anti-glare structures in the prior art that rely on complex partitions and sensors, this solution, with its simple design of a single red light absorption layer 1, significantly reduces production costs and complexity, while ensuring clear vision and significantly improving driving safety. It effectively solves the problems of high cost and poor anti-glare effect in the prior art.

[0050] In the above embodiments, the material of the red light absorbing layer 1 can be selected as rare earth resin, with rare earth elements (such as Sm) as the main components. 3+ The materials used include polymer matrices (such as methacrylic acid and styrene copolymer resin) and functional additives. Rare earth elements in rare earth resins, due to their unique electronic transition characteristics, exhibit high absorption efficiency for photons in the red light band, effectively reducing red light transmittance while maintaining good transmittance for other visible light bands, ensuring the driver's visibility remains unaffected. Furthermore, rare earth resins possess excellent weather resistance and chemical stability, resisting the erosion of harsh environmental factors such as ultraviolet radiation, high temperatures, and humidity, ensuring the long-term stability and reliability of the filter structure 20. Therefore, using rare earth resin as the material for the red light absorption layer 1 not only achieves a highly efficient light filtering effect but also ensures the durability and safety of the windshield light-transmitting structure 100, providing the driver with a safer and more comfortable driving environment.

[0051] Of course, in other embodiments, the material of the red light absorbing layer 1 can also be other materials with red light absorption properties, such as some polymer materials with absorption properties.

[0052] In the above implementation example, the light-filtering structure 20 is designed as a red light-absorbing layer 1 placed on the windshield light-transmitting body 10, achieving efficient absorption and blocking of red light. This red light-absorbing layer 1 is made of a specific material and has excellent red light absorption capabilities, which can effectively reduce the glare caused to the driver by the red light of the taillights of the vehicle in front. Furthermore, the red light-absorbing layer 1 is tightly connected to the windshield light-transmitting body 10, ensuring the stability of the structure and the durability of the filtering effect.

[0053] In some embodiments, the windproof and light-transmitting body 10 includes a multi-layer light-transmitting structure.

[0054] In the above embodiments, please refer to Figure 4 The multi-layer light-transmitting structure is a composite structure based on the synergistic optimization design of structural mechanics and optical functions. It enhances the windshield's impact and deformation resistance through interlayer mutual support, effectively resisting external forces such as wind pressure and vibration during vehicle operation. At the same time, the red light absorption layer 1 is sandwiched in it, providing it with physical protection to avoid external environmental erosion and ensure the long-term stable operation of the red light absorption layer 1. Compared with the anti-glare structure of the prior art that relies on complex partitions and sensors, this solution significantly improves the anti-glare effect and structural stability while reducing production costs and simplifying the production process through the simple design of the multi-layer light-transmitting structure. It effectively solves the problems of high cost, fragile structure and poor anti-glare effect in the prior art.

[0055] Optionally, in the above implementation examples, the multi-layer light-transmitting structure can be a double-layer, triple-layer, or higher structure, with the specific number of layers determined according to actual needs and design requirements.

[0056] Please see Figure 2 and Figure 4 In some embodiments, the multilayer light-transmitting structure includes a first light-transmitting structure 2 and a second light-transmitting structure 3, with the red light absorbing layer 1 located between the first light-transmitting structure 2 and the second light-transmitting structure 3.

[0057] In the above embodiments, the first light-transmitting structure 2 and the second light-transmitting structure 3 form a stable double-layer architecture, with mutual support between the layers. This greatly enhances the windshield's ability to withstand external forces such as wind pressure, vibration, and collisions during vehicle operation, effectively reducing the risk of structural damage. Simultaneously, the red light-absorbing layer 1 is sandwiched in the middle, providing it with excellent physical protection and preventing performance degradation due to external factors such as rain erosion, sand and dust abrasion, and ultraviolet radiation. This ensures that the red light-absorbing layer 1 stably absorbs the red light from the taillights of the vehicle in front, reducing the risk of glare for drivers behind. Compared to existing high-cost anti-glare structures that rely on complex partitions and sensors, this solution, through a simple double-layer light-transmitting design with a functional layer sandwiched in the middle, significantly improves the anti-glare effect and structural reliability while reducing production costs and simplifying the manufacturing process. It effectively solves the problems of high cost and unsustainable anti-glare effects in existing technologies.

[0058] Optionally, the aforementioned multi-layered light-transmitting structure can be configured with three or more layers. In multi-layered light-transmitting structures with three or more layers, additional light-transmitting layers or functional layers can be added on top of the double-layer structure to further improve the performance of the windshield light-transmitting structure 100. For example, an ultraviolet-protective layer can be added to block ultraviolet rays from harming the driver and vehicle; or an anti-scratch layer can be added to improve the wear resistance and service life of the windshield. These additional layer structures can be flexibly designed and adjusted according to specific needs to meet the requirements of different vehicle models and usage environments.

[0059] Please see Figure 1 and Figure 4 In some embodiments, the windproof and light-transmitting body 10 also includes an adhesive layer 4.

[0060] In the above embodiments, the selection of adhesive layer 4 needs to consider its adhesive strength and optical properties to ensure tight adhesion between the layers, avoid light refraction and leakage, and maintain long-term stability and reliability. Through reasonable design and selection of adhesive layer 4, the windshield light-transmitting structure 100 of this application can maintain excellent anti-glare effect and visual clarity in various complex and changing driving environments, providing drivers with a safer and more comfortable driving experience.

[0061] For example, the adhesive layer 4 is made of PVB (Polyvinyl butyral) material and is located between the first light-transmitting structure 2 and the second light-transmitting structure 3, serving as an adhesive and buffer. The PVB interlayer material has good adhesion and toughness, effectively connecting the various structural layers to form a stable whole. Simultaneously, PVB material also has certain sound absorption and vibration damping effects, reducing noise and vibration generated during vehicle operation and improving driving comfort. Furthermore, the PVB interlayer material also has certain heat insulation properties, blocking external heat from entering the vehicle interior to a certain extent, providing a more comfortable driving environment for the driver. By introducing the PVB adhesive layer 4, the windshield light-transmitting structure 100 of this application maintains efficient light filtering performance while further improving the stability and durability of the structure, providing the driver with a safer and more comfortable driving experience.

[0062] Optionally, the adhesive layer 4 can also be made of a transparent adhesive with high light transmittance, weather resistance, and anti-aging properties, such as polyurethane adhesive, acrylic adhesive, or silicone adhesive. These adhesive layer 4 materials not only provide strong adhesive strength, ensuring a tight connection between the layers, but also effectively prevent light refraction and leakage between layers, maintaining the overall optical performance of the windproof and light-transmitting structure 100. Simultaneously, these adhesive layer 4 materials have good weather resistance and anti-aging capabilities, resisting the erosion of harsh environmental factors such as ultraviolet radiation, high temperatures, and humidity, ensuring that the windproof and light-transmitting structure 100 maintains a stable anti-glare effect and clear vision during long-term use.

[0063] Please see Figure 2 and Figure 4 In some embodiments, the adhesive layer 4 is disposed between the first light-transmitting structure 2 and the second light-transmitting structure 3.

[0064] In the above embodiment, the adhesive layer 4 is placed between the first light-transmitting structure 2 and the second light-transmitting structure 3, forming a stable structural system. It not only enhances the overall strength of the windshield light-transmitting structure 100 but also ensures that the red light absorption layer 1 can function stably without external interference. The presence of the adhesive layer 4 allows the windshield light-transmitting structure 100 to maintain excellent performance and stability even in complex and changing driving environments, providing the driver with a clear and safe field of vision.

[0065] Specifically, adhesive layer 4 is a key connecting component designed based on structural mechanics and functional stability requirements. Leveraging its adhesive properties, it forms strong cohesion between the first light-transmitting structure 2 and the second light-transmitting structure 3, ensuring the multi-layered structure maintains its integrity and prevents layer separation even under conditions of wind pressure, vibration, and temperature changes during vehicle operation. Simultaneously, the stable connection of adhesive layer 4 ensures the fixed position of the red light absorbing layer 1, preventing displacement or damage due to external forces, thus continuously and efficiently absorbing the red light from the taillights of the vehicle ahead, reducing the risk of driver glare. Compared to the high-cost anti-glare structures in existing technologies that rely on complex partitions and sensors, this solution, through the simple design of adding adhesive layer 4, significantly improves structural stability and the durability of the anti-glare function without adding precision electronic components and complex control systems. It effectively reduces production costs and solves the problems of structural instability, high cost, and difficulty in guaranteeing anti-glare effects in existing technologies.

[0066] Please see Figure 4 In some embodiments, the first light-transmitting structure 2 is located on the side of the second light-transmitting structure 3 facing the passenger compartment of the vehicle, and the red light absorbing layer 1 is disposed between the first light-transmitting structure 2 and the adhesive layer 4 or between the second light-transmitting structure 3 and the adhesive layer 4.

[0067] In the above embodiment, the first light-transmitting structure 2 is designed to face the passenger compartment, primarily for safety considerations and improved visibility. This layout ensures that when the driver faces the red light emitted by the taillights of the vehicle ahead, the red light is first captured and filtered by the red light absorption layer 1, reducing glare. Simultaneously, as the layer closest to the driver, the first light-transmitting structure 2 is designed with safety and comfort in mind in terms of material and surface treatment, providing a good visual experience and impact resistance.

[0068] When the red light absorbing layer 1 is positioned between the first light-transmitting structure 2 and the adhesive layer 4, it can efficiently intercept red light at the position closest to the driver, ensuring that the red light in the driver's field of vision is minimized. In addition, the presence of the adhesive layer 4 can also provide additional fixation and protection for the red light absorbing layer 1, preventing it from shifting or falling off due to vibration or external impact during long-term use.

[0069] On the other hand, when the red light absorbing layer 1 is positioned between the second light-transmitting structure 3 and the adhesive layer 4, it can also effectively filter red light. However, in this case, the first light-transmitting structure 2 takes on more of the task of protecting the red light absorbing layer 1 and providing a clear field of vision. This design also ensures that the driver has a clear and glare-free visual experience when facing the taillights of the vehicle in front.

[0070] Regardless of which layer of light-transmitting structure and adhesive layer 4 the red light-absorbing layer 1 is located between, the windproof and light-transmitting structure 100 of this application can solve the problems of high cost and poor effect of the anti-glare structure in the prior art in a simple and efficient way.

[0071] Optionally, considering the sequence of the spraying process, the red light absorbing layer 1 can still be placed between the red light absorbing layer 1 and the adhesive layer 4 to facilitate the spraying operation.

[0072] In the above embodiment, this interlayer positioning is an innovative design based on the synergistic optimization of mechanical performance and optical function. The layout of the first light-transmitting structure 2 facing the passenger compartment allows it to preferentially withstand impacts from external wind pressure, stone impacts, etc., providing buffer protection for the entire windshield structure and improving its resistance to damage. The specific positional relationship between the red light absorbing layer 1, the adhesive layer 4, and the light-transmitting structure, with the bonding and fixing effect of the adhesive layer 4, ensures that the red light absorbing layer 1 can maintain its position and be in optimal working condition during long-term vehicle operation, even under complex conditions such as vibration and temperature changes. It can continuously and efficiently absorb the red light emitted by the taillights of the vehicle in front, reducing the risk of glare for drivers behind. Compared with the existing high-cost anti-glare structures that rely on complex partitions and sensors, this solution, through precise interlayer positioning design, significantly improves the stability of the structure and the reliability of the anti-glare function without adding precision electronic components and complex control systems, effectively reducing production costs and successfully solving the problems of complex structure, high cost, and difficulty in guaranteeing anti-glare effect in the prior art.

[0073] Please see Figure 4 In some embodiments, the thickness of the adhesive layer 4 is 0.9 mm, the thickness of the first light-transmitting structure 2 and the second light-transmitting structure 3 is 2 mm, and the thickness of the red light absorbing layer 1 is 0.1 mm.

[0074] In the above embodiments, the specific layer thickness design of the adhesive layer 4, the first light-transmitting structure 2, and the second light-transmitting structure 3 is based on a comprehensive consideration of structural strength, optical performance, and manufacturing process. A 0.9mm thickness of the adhesive layer 4 provides sufficient bonding strength and stability, ensuring a tight fit between the layers, preventing light refraction and leakage, while maintaining long-term weather resistance and reliability. A 2mm thickness of the first light-transmitting structure 2 and the second light-transmitting structure 3 balances impact resistance and lightweight requirements, reducing the overall weight of the windshield while maintaining structural strength, thus improving vehicle fuel economy and handling performance. The 0.1mm thickness of the red light absorbing layer 1 is based on its material properties and optical design, ensuring efficient absorption of red light without affecting the windshield's light transmittance and visibility. This thickness design ensures both structural stability and durability, as well as the high efficiency and reliability of the anti-glare function, providing drivers with a safer and more comfortable driving environment. Of course, in practical applications, these layer thicknesses can be flexibly adjusted and optimized according to specific vehicle models, usage environments, and manufacturing process requirements to meet the needs of different customers.

[0075] For example, the thickness error of both the adhesive layer 4 and the red light absorption layer 1 is controlled within 10%. This error control range ensures both the feasibility of the production process and the stability and consistency of the optical performance of each layer. Through strict process control and quality inspection, the windshield light-transmitting structure 100 of this application can maintain excellent anti-glare effect and visual clarity in various complex and changing driving environments, providing drivers with safer and more reliable driving protection.
