Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more particularly to a window glass assembly and a vehicle. Background Technology

[0002] Vehicle windows often contain sodium ions. Over time, these ions can leach out, and plastic components and adhesives inside the vehicle can release volatile organic compounds. These compounds react with sodium ions in the presence of water vapor, forming opaque sodium salt precipitates. This increases the haze on the window surface, hindering light transmission and reducing the driving experience for passengers. Summary of the Invention

[0003] This application provides a vehicle window glass assembly and a vehicle that maintains low fog and high visible light transmittance of the window glass assembly during long-term vehicle use, thereby improving driving safety and the driving experience of passengers.

[0004] This application provides a vehicle window glass assembly for use in a vehicle, comprising a window glass and a molecular sieve layer. The material of the window glass contains sodium ions. The window glass has an inner surface, which is the surface of the window glass facing the interior of the vehicle. The window glass includes a signal transmission area. The molecular sieve layer is disposed on the inner surface and covers at least a portion of the signal transmission area. The lattice gap of at least one layer in the molecular sieve layer is smaller than the diameter of the sodium ions.

[0005] The molecular screening layer completely covers the signal transmission region.

[0006] The refractive index of the molecular screening layer is less than that of the window glass.

[0007] The difference between the refractive index of the window glass and the refractive index of the molecular sieve layer is greater than 0.1.

[0008] The molecular screening layer includes an optically extended layer, the refractive index of which is less than that of the window glass.

[0009] The inter-lattice gap of the optically extended layer is smaller than the diameter of the sodium ion.

[0010] The material of the optically extended layer includes at least one of silicon oxide, magnesium fluoride, and aluminum oxide.

[0011] The molecular screening layer further includes a light confinement layer, which is located between the inner surface and the light extension layer. The refractive index of the light confinement layer is greater than the refractive index or equivalent refractive index of the window glass.

[0012] Wherein, the lattice gap of at least one of the light confinement layer and the light extension layer is smaller than the diameter of the sodium ion.

[0013] The material of the light confinement layer includes at least one of silicon nitride, silicon oxynitride, titanium oxide, niobium oxide, zirconium oxide, zinc tin oxide, cerium oxide, and tantalum oxide.

[0014] The molecular screening layer further includes a ground layer, which is disposed on the inner surface and located between the light confinement layer and the inner surface.

[0015] The base layer material includes silicon dioxide.

[0016] There are multiple light extension layers and multiple light constraint layers. At least one light constraint layer is disposed on the surface of the base layer away from the window glass. Multiple light extension layers and multiple light constraint layers are alternately arranged.

[0017] The window glass assembly further includes a functional layer, which is disposed on the side of the molecular sieve layer opposite to the window glass.

[0018] The functional layer includes at least one of a transparent conductive film layer, a hydrophobic film layer, an anti-fingerprint film layer, and an anti-fog layer.

[0019] The vehicle window glass includes a visible area and a non-visible area, the non-visible area being arranged around the visible area, and the molecular screening layer covering at least a portion of the visible area.

[0020] The vehicle window glass includes a first glass and a second glass, the second glass being located on the side of the first glass facing the interior of the vehicle and spaced apart from the first glass, the second glass including an inner surface, and at least the material of the second glass containing sodium ions.

[0021] This application also provides a vehicle comprising a body and a window glass assembly as described above, the window glass assembly being mounted on the body.

[0022] This application provides a molecular sieve layer on the inner surface of the vehicle window glass, with the lattice gap of at least one layer of the molecular sieve layer being smaller than the diameter of sodium ions. This prevents sodium ions from passing through the molecular sieve layer to the side of the vehicle window glass assembly closest to the vehicle interior, thereby preventing sodium ions from reacting with volatile organic compounds in the vehicle interior environment. This avoids the formation of sodium salt deposits on the surface of the vehicle window glass assembly, which would affect the overall visible light transmittance of the vehicle window glass assembly. This improves the overall visible light transmittance of the vehicle window glass assembly, thereby enhancing driving safety and the driving experience of passengers. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Please see Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of the vehicle 1000 provided in the embodiments of this application.

[0028] This application provides a vehicle 1000, which includes a body 100 and a window glass assembly 200. The body 100 may be a sheet metal part. The window glass assembly 200 is mounted on the body 100. In this embodiment, the window glass assembly 200 serves as a windshield. In other embodiments, the window glass assembly 200 may also serve as a rear windshield, sunroof, triangular window, or B-pillar glass in the vehicle 1000.

[0029] Please see Figure 2 , Figure 2 yes Figure 1 A schematic diagram of the planar structure of the window glass assembly 200 in the vehicle 1000 shown.

[0030] The window glass assembly 200 includes a window glass 300 and a molecular screening layer 400. The window glass 300 includes a signal transmission area 300a, a non-visible area 300d, and a visible area 300c. The non-visible area 300d is arranged around the visible area 300c and around the signal transmission area 300a. The signal transmission area 300a can be used to transmit optical signals from in-vehicle sensors. In-vehicle sensors can identify the external environment of the vehicle 1000 through the signal transmission area 300a. These in-vehicle sensors include sensors such as cameras or video cameras. The non-visible area 300d includes a shielding area 300b. The shielding area 300b is arranged around the signal transmission area 300a. The visible area 300c is located in the center of the window glass 300. External light can enter the interior of the vehicle 1000 through the visible area 300c, and light from inside the vehicle 1000 can also enter the external environment through the visible area 300c. In this embodiment, the visible area 300c and the signal transmission area 300a are spaced apart. In some other embodiments, the visible area 300c may be connected to the signal transmission area 300a, and this application does not impose any limitations on this.

[0031] Please see Figure 3 , Figure 3 yes Figure 2 The diagram shows the structure of the vehicle window glass assembly 200 in the first embodiment.

[0032] The vehicle window glass 300 can be a single-pane glass or a laminated glass. In this embodiment, the vehicle window glass 300 is a single-pane glass. The vehicle window glass 300 has an inner surface 301 and an outer surface 302. The inner surface 301 is the surface of the vehicle window glass 300 facing the interior of the vehicle 1000. The outer surface 302 is the surface of the vehicle window glass 300 facing the exterior of the vehicle 1000 and is disposed opposite to the inner surface 301. The thickness of the vehicle window glass 300 is greater than or equal to 1.6 mm and less than or equal to 6 mm. The visible light transmittance of the vehicle window glass 300 is greater than or equal to 75%.

[0033] The material of the window glass 300 includes sodium ions. In this embodiment, the window glass 300 can be soda-lime float glass. It should be noted that during long-term use, sodium ions will precipitate onto the inner surface 301 of the window glass 300. The sodium ions precipitated from the existing window glass 300 will react with volatile organic compounds in the vehicle under the action of water vapor to form sodium salt precipitates, which will increase the haze of the window glass assembly 200 and thus affect the visible light transmittance of the window glass assembly 200. In some other embodiments, the window glass 300 can also be borosilicate glass, quartz glass, or other glass that does not contain sodium ions, and this application does not limit this.

[0034] A molecular screening layer 400 is disposed on the inner surface 301 and covers at least a portion of the signal transmission region 300a. The molecular screening layer 400 is a single-layer structure or a multi-layer composite structure. The interlayer spacing of at least one layer in the molecular screening layer 400 is smaller than the diameter of a sodium ion. In this embodiment, the molecular screening layer 400 completely covers the signal transmission region 300a and is a single-layer structure. In some other embodiments, the molecular screening layer 400 may also cover at least a portion of the visible region 300c; this application does not impose limitations on this.

[0035] The molecular sieving layer 400 includes an optically extended layer 410. The lattice gaps of the optically extended layer 410 are smaller than the diameter of sodium ions, thus preventing sodium ions from passing through the molecular sieving layer 400 to the side of the window glass assembly 200 closest to the interior of the vehicle 1000. Simultaneously, since the diameter of volatile organic compound molecules in the interior environment of the vehicle 1000 is larger than the diameter of sodium ions, volatile organic compounds cannot pass through the molecular sieving layer 400 to reach the inner surface 301 and contact sodium ions. This prevents sodium ions from reacting with volatile organic compounds, avoiding the formation of sodium salt deposits on the surface of the window glass assembly 200, which would affect the visible light transmittance of the window glass assembly 200. During the long-term use of the vehicle 1000, this helps maintain low haze and high visible light transmittance of the window glass assembly 200, thereby improving driving safety and the driving experience for passengers. For example, the lattice gap of the optical extension layer 410 is less than 0.196 nm to ensure that the lattice gap of the optical extension layer 410 is less than the diameter of sodium ions (0.196 nm), thereby ensuring that the molecular sieve layer 400 effectively blocks sodium ions from passing through the molecular sieve layer 400.

[0036] It should be noted that in some other embodiments, when the material composition of the window glass 300 contains other metal cations such as potassium, the window glass 300 may also precipitate potassium and other metal cations. In this case, since the ion diameters of potassium and other metal cations are almost all larger than those of sodium ions, the molecular sieve layer 400 can also block these metal cations from reaching the side of the window glass assembly 200 facing the interior of the vehicle 1000, so as to avoid these metal cations reacting with volatile organic compounds and affecting the visible light transmittance of the window glass assembly 200.

[0037] In this embodiment, the refractive index of the light-extending layer 410 is lower than that of the window glass 300, so that the refractive index of the molecular sieving layer 400 is also lower than that of the window glass 300. This reduces light reflection loss at the window glass assembly 200, thereby increasing the visible light transmittance of the window glass assembly 200, which is beneficial for improving driving safety and the driving experience of passengers. Furthermore, the difference between the refractive index of the window glass 300 and the refractive index of the molecular sieving layer 400 is greater than 0.1, further reducing light reflection at the molecular sieving layer 400, thereby further increasing the visible light transmittance of the window glass assembly 200. It should be noted that the greater the difference between the refractive index of the window glass 300 and the refractive index of the molecular sieving layer 400, the better the effect of reducing light reflection loss at the molecular sieving layer 400, and thus the better the effect of improving the visible light transmittance of the window glass assembly 200. It should be noted that the refractive index of the molecular sieve layer 400 is the overall refractive index of the molecular sieve layer 400, which is also the equivalent refractive index of the molecular sieve layer 400. The refractive index of the window glass 300 is the overall refractive index of the window glass 300, which is also the equivalent refractive index of the window glass 300.

[0038] In this embodiment, the thickness of the optical extension layer 410 is greater than or equal to 5 nm and less than or equal to 100 nm. The material of the optical extension layer 410 includes at least one of silicon oxide, magnesium fluoride, and aluminum oxide. The molecular screening layer 400 can be deposited on the inner surface 301 by evaporation deposition, magnetron sputtering deposition, molecular beam epitaxy, various chemical vapor deposition, or atomic layer deposition methods.

[0039] Please see Figure 4 , Figure 4 yes Figure 2 The diagram shows the structure of the vehicle window glass assembly 200 in the second embodiment.

[0040] The difference between this embodiment and the first embodiment is that the molecular screening layer 400 can cover at least part of the signal transmission area 300a to reduce the light reflection loss in a local area of ​​the window glass assembly 200, thereby improving the visible light transmittance of the partial signal transmission area 300a of the window glass assembly 200.

[0041] Please see Figure 5 , Figure 5 yes Figure 2 The diagram shows the structure of the vehicle window glass assembly 200 in the third embodiment.

[0042] The difference between this embodiment and the first embodiment is that the molecular screening layer 400 is a multi-layer composite structure. The molecular screening layer 400 also includes a light confinement layer 450. The light confinement layer 450 is located between the light extension layer 410 and the inner surface 301. In the multi-layer structure of the molecular screening layer 400, the lattice gap of at least one layer is smaller than the diameter of a sodium ion. Specifically, the lattice gap of at least one layer in the light confinement layer 450 and the light extension layer 410 is smaller than the diameter of a sodium ion, thus preventing sodium ions from passing through the molecular screening layer 400 to the side of the window glass assembly 200 near the interior of the vehicle 1000. This prevents sodium ions from reacting with volatile organic compounds in the interior environment of the vehicle 1000, avoiding the formation of sodium salt deposits on the surface of the window glass assembly 200 that would affect the visible light transmittance and haze of the window glass assembly 200. This helps maintain high visible light transmittance and low haze of the window glass assembly 200, thereby improving driving safety and the driving experience of passengers. For example, the lattice gap of at least one of the light confinement layer 450 and the light extension layer 410 is less than 0.196 nm. The diameter of the sodium ion is 0.196 nm.

[0043] In this embodiment, the refractive index of the light confinement layer 450 is greater than that of the window glass 300, so that the overall refractive index of the superimposed light confinement layer 450 and light extension layer 410 is less than that of the window glass 300 and less than that of the light extension layer 410. That is, the refractive index of the light confinement layer 450 is greater than that of the window glass 300, so that the refractive index of the molecular sieving layer 400 is less than that of the window glass 300 and less than that of the light extension layer 410. This further reduces light reflection loss on the window glass assembly 200, thereby further improving the visible light transmittance of the window glass assembly 200, which is beneficial for improving driving safety and the driving experience of passengers. In some other embodiments, when the window glass 300 is laminated glass, the refractive index of the light confinement layer 450 is greater than the equivalent refractive index of the window glass 300, so that the equivalent refractive index of the molecular sieving layer 400 is less than the equivalent refractive index of the window glass 300, and less than the refractive index of the light extension layer 410.

[0044] In this embodiment, the thickness of the light confinement layer 450 is greater than or equal to 5 nm and less than or equal to 200 nm. The material of the light confinement layer 450 includes at least one selected from silicon nitride, silicon oxynitride, titanium oxide, niobium oxide, zirconium oxide, zinc tin oxide, cerium oxide, and tantalum oxide.

[0045] Please see Figure 6 , Figure 6 yes Figure 2 The diagram shows the structure of the vehicle window glass assembly 200 in the fourth embodiment.

[0046] The difference between this embodiment and the third embodiment is that the molecular screening layer 400 further includes a substrate 480. The substrate 480 is disposed on the inner surface 301 and located between the inner surface 301 and the light-constraining layer 450; that is, the light-constraining layer 450 is disposed on the surface of the substrate 480 facing away from the window glass 300. The substrate 480 enhances the adhesion of the molecular screening layer 400, thereby improving the firmness of the molecular screening layer 400 on the inner surface 301, which is beneficial for the molecular screening layer 400 to function better. The material of the substrate 480 includes silicon oxide.

[0047] In this embodiment, the overall refractive index of the superimposed base layer 480, light confinement layer 450, and light extension layer 410 is less than the refractive index of the window glass 300. This makes the equivalent refractive index of the molecular sieving layer 400 less than the refractive index of the window glass 300, thereby reducing light reflection loss on the window glass assembly 200 and improving the visible light transmittance of the window glass assembly 200. This is beneficial for improving driving safety and the driving experience of passengers. It should be noted that when the window glass 300 is laminated glass, the equivalent refractive index of the molecular sieving layer 400 is less than the equivalent refractive index of the window glass 300.

[0048] Please see Figure 7 and Figure 8 , Figure 7 yes Figure 2 The diagram shows the structure of the window glass assembly 200 in the first case of the fifth embodiment. Figure 8 yes Figure 7 The diagram shows the structure of the window glass assembly 200 in the second case of the fifth embodiment.

[0049] This embodiment differs from the fourth embodiment in that the molecular sieving layer 400 contains multiple light-confining layers 450 and multiple light-extending layers 410. The multiple light-confining layers 450 are spaced apart, and at least one light-confining layer 450 is disposed on the surface of the base layer 480 facing away from the window glass 300. The multiple light-extending layers 410 are spaced apart and alternate with the multiple light-confining layers 450. Each light-extending layer 410 corresponds to one light-confining layer 450. In the multilayer structure of the molecular sieving layer 400, the interlayer spacing of at least some layers is smaller than the diameter of a sodium ion. Specifically, at least one of the multiple light-confining layers 450 and multiple light-extending layers 410 has a lattice gap smaller than the diameter of sodium ions, so as to block sodium ions from passing through the molecular sieving layer 400 to reach the side of the window glass assembly 200 near the interior of the vehicle 1000, thereby preventing sodium ions from reacting with volatile organic compounds in the interior environment of the vehicle 1000, avoiding the formation of sodium salt deposits on the surface of the window glass assembly 200, which would affect the overall visible light transmittance and haze of the window glass assembly 200. This helps to maintain the high visible light transmittance and low haze of the window glass assembly 200, thereby improving driving safety and the driving experience of passengers.

[0050] In this embodiment, the overall refractive index of the superimposed base layer 480, multiple light-constraining layers 450, and multiple light-extending layers 410 is lower than the refractive index of the window glass 300. This makes the equivalent refractive index of the molecular sieving layer 400 lower than that of the window glass 300, further reducing light reflection loss on the window glass assembly 200 and thus improving the visible light transmittance of the window glass assembly 200, which is beneficial for improving driving safety and the driving experience of passengers. Furthermore, the molecular sieving layer, formed by the superimposed multiple light-constraining layers and multiple light-extending layers, has a better effect on increasing visible light transmittance over long-term use of the window glass, and its effect covers a wider range of visible light wavelengths, further enhancing driving safety and the driving experience of passengers. It should be noted that when the window glass 300 is laminated glass, the equivalent refractive index of the molecular sieving layer 400 is lower than that of the window glass 300. The thicknesses of the multiple light confinement layers 450 and the multiple light extension layers 410 may be unequal or equal; this application does not impose any limitations on this. For example, in the first embodiment, there are two light confinement layers 450 and two light extension layers 410. In the second embodiment, there are three light confinement layers 450 and three light extension layers 410.

[0051] Please see Figure 9 , Figure 9 yes Figure 2 The diagram shows the structure of the vehicle window glass assembly 200 in the sixth embodiment.

[0052] The difference between this embodiment and the first embodiment is that the vehicle window glass 300 is laminated glass. The visible light transmittance of the vehicle window glass 300 is greater than or equal to 75%, ensuring high clarity for occupants to observe their surroundings. The thickness of the vehicle window glass 300 is greater than or equal to 3mm and less than or equal to 8mm. Specifically, the vehicle window glass 300 includes a first glass 310, a second glass 320, and a connecting layer 330. The second glass 320 and the first glass 310 are spaced apart and opposite to each other. The connecting layer 330 is located between the first glass 310 and the second glass 320.

[0053] The first glass 310 is the glass of the vehicle window 300 located near the exterior of the vehicle 1000. The first glass 310 includes a first surface 211 and a second surface 212. The first glass 310 includes an outer surface 302. In this embodiment, the first glass 310 may be soda-lime float glass. In some other embodiments, the first glass 310 may also be borosilicate glass, quartz glass, or other sodium-free glass, and this application does not impose any limitations on this.

[0054] The second glass 320 is located on the side of the first glass 310 facing the interior of the vehicle 1000 and is spaced apart from the first glass 310. The second glass 320 includes an inner surface 301. In this embodiment, at least the material of the second glass 320 contains sodium ions. Exemplarily, the second glass 320 is soda-lime float glass. In some other embodiments, the second glass 320 may be a sodium-free glass such as borosilicate glass or quartz glass. It should be noted that when the second glass 320 is a sodium-free glass, sodium ions will not precipitate from the second glass 320 itself, and sodium salt deposits will not form on its surface.

[0055] The connecting layer 330 is located between the first glass 310 and the second glass 320, and is bonded between the first glass 310 and the second glass 320. In this embodiment, the connecting layer 330 may be made of polyvinyl butyral (PVB). In other embodiments, the connecting layer 330 may also be made of other materials such as polyvinyl chloride (PVC), polyurethane (PU), ionomer resin, silicone resin, polyvinyl acetate, ethylene-vinyl acetate copolymer (EVA), ionic polymers, and optical clear adhesive (OCA).

[0056] A molecular screening layer 400 is disposed on the inner surface 301 of the second glass 320 and completely covers the signal transmission area 300a of the window glass 300 to improve the overall visible light transmittance of the window glass assembly 200, thereby enhancing driving safety and the driving experience of passengers. In this embodiment, the refractive index of the light extension layer 410 is less than the equivalent refractive index of the window glass 300.

[0057] Please see Figure 10 , Figure 10 yes Figure 2 The diagram shows the structure of the vehicle window glass assembly 200 in the seventh embodiment.

[0058] The difference between this embodiment and the sixth embodiment is that the molecular screening layer 400 partially covers the signal transmission region 300a to reduce light reflection loss in local areas of the window glass assembly 200, thereby improving the visible light transmittance in local areas of the window glass assembly 200, and also enhancing driving safety and the driving experience of passengers.

[0059] Please see Figure 11 , Figure 11 yes Figure 2 The diagram shows the structure of the vehicle window glass assembly 200 in the eighth embodiment.

[0060] This embodiment differs from the first embodiment in that the window glass assembly 200 further includes a functional layer 500. The functional layer 500 is disposed on the side of the molecular sieve layer 400 facing away from the window glass 300. The functional layer 500 includes at least one of a transparent conductive film layer, a hydrophobic film layer, an anti-fingerprint film layer (AF), and an anti-fog layer. For example, providing a transparent conductive film can enhance the defrosting and defogging function of the window glass assembly 200. Providing a hydrophobic film layer prevents water droplets from adhering to the inner surface 301, avoiding water droplets obstructing vision and reducing the accumulation of stains, keeping the window glass 300 a clean surface, improving the clarity of the window glass assembly 200, thereby improving driving safety and the driving experience of passengers. Providing an anti-fingerprint film layer (AF) can prevent fingerprints, grease, and other stains from leaving marks on the window, keeping the inner surface 301 of the window glass 300 clean, thereby improving the clarity of the window glass assembly 200, and thus improving driving safety and the driving experience of passengers. The anti-fog layer effectively prevents fogging of the windows in humid or temperature-sensitive conditions, thus avoiding obstructed vision and improving driving safety and the driving experience for passengers.

[0061] It should be noted that the setting of functional layer 500 may slightly weaken the effect of molecular sieve layer 400 on improving the visible light transmittance of window glass assembly 200, and the setting of functional layer 500 may not affect the effect of molecular sieve layer 400 on improving the visible light transmittance of window glass assembly 200.

[0062] A comparative experiment was conducted on the vehicle window glass assembly 200 in the first case of the fifth embodiment of this application. The conditions for Comparative Example 1 were as follows: a windshield sample with dimensions of 300*300mm, structured as follows: 2.1mm soda-lime float glass + 0.76mm 330PVB connecting layer + 2.1mm soda-lime float glass. The windshield sample was sealed and fixed on a small experimental vehicle. A camera bracket was fixed to the surface of the windshield sample facing the inside of the experimental vehicle. The surface of the windshield sample facing the inside of the experimental vehicle was in contact with the interior environment of the experimental vehicle, while the surface of the windshield sample facing the outside of the experimental vehicle was in contact with the external environment. The experimental vehicle was placed in a comprehensive vehicle performance environmental test chamber for the experiment. The test chamber simulated sunlight exposure conditions: ambient temperature of 95℃, humidity of 70%RH, and continuous testing for 168 hours. The experimental conditions for the following comparative examples and embodiments are the same and will not be repeated. Comparative Example 2: A windshield sample with dimensions of 300*300mm, consisting of 2.1mm soda-lime float glass + 0.76mm PVB + 2.1mm borosilicate glass; Comparative Example 3: A windshield sample with dimensions of 300*300mm, consisting of 2.1mm soda-lime float glass + 0.76mm PVB + 2.1mm quartz glass; Example 1: A car window glass 300 with dimensions of 300*300mm has the following structure: a 2.1mm first glass 310 (sodium-calcium float glass) + a 0.76mm connecting layer 330 (PVB) + a 2.1mm second glass 320 (sodium-calcium float glass). A molecular sieve layer 400 is applied to the inner surface 301 of the car window glass 300. The molecular sieve layer 400 has a five-layer structure, and the materials of the five layers are: the base layer 480 is made of silicon dioxide (SiO2), the two light confinement layers 450 are both made of titanium trioxide (Ti3O5), and the two light extension layers 410 are both made of magnesium fluoride (MgF2). The five-layer structure of the molecular screening layer 400, from the base layer 480 to the optical extension layer 410, consists of the following layers in sequence: a 30.15 nm base layer 480, a 16.73 nm optical confinement layer 450, a 23.16 nm optical extension layer 410, a 109.73 nm optical confinement layer 450, and an 85.19 nm optical extension layer 410.

[0063] The results of the control experiment are shown in the table below.

[0064]

[0065] The results of Comparative Example 1 show that ordinary sodium-calcium float glass without the molecular sieve layer 400 experienced a 2.91% loss in visible light transmittance and a significant increase in haze after the experiment.

[0066] As can be seen from the results of Example 1, the visible light transmittance of the window glass assembly 200 under the fifth embodiment increased by 3.59% after the experiment.

[0067] Based on the results of Example 1, Comparative Example 2 and Comparative Example 3, it can be seen that before and after the experiment, the visible light transmittance and haze changes of the window glass assembly 200 are comparable to those of the silicate glass in Comparative Example 2 and the quartz glass in Comparative Example 3. The window glass assembly 200 can maintain high visible light transmittance and low haze, which can ensure the normal operation of functional components such as cameras.

[0068] Experiments show that during long-term use, the addition of the molecular sieving layer 400 to the window glass assembly 200 can maintain low haze and high visible light transmittance, thereby improving the clarity of the window glass assembly 200 and enhancing driving safety and the driving experience of passengers.

[0069] This application provides a molecular sieving layer 400 on the inner surface 301 of the window glass 300, and ensures that the lattice gaps in at least one layer of the molecular sieving layer 400 are smaller than the diameter of sodium ions. This prevents sodium ions from passing through the molecular sieving layer 400 and reaching the side of the window glass assembly 200 closest to the vehicle 1000, thereby preventing sodium ions from reacting with volatile organic compounds in the vehicle 1000's interior environment. This avoids the formation of sodium salt deposits on the surface of the window glass assembly 200, which would affect the visible light transmittance and haze of the window glass assembly 200. This helps maintain high visible light transmittance and low haze in the window glass assembly 200, thus improving driving safety and the driving experience for passengers. Simultaneously, by making the equivalent refractive index of the molecular sieving layer 400 smaller than the refractive index or equivalent refractive index of the window glass 300, the reflection loss of light on the window glass assembly 200 can be reduced, further improving the visible light transmittance of the window glass assembly 200, which is beneficial for enhancing driving safety and the driving experience for passengers. In addition, a functional layer 500 can be added to the side of the molecular screening layer 400 away from the window glass 300 to increase the functionality of the window glass assembly 200 and further enhance the driving experience for passengers.
