[0039] 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. Figure 2 yes Figure 1 The diagram shows the structure of the window glass assembly 200 and adhesive 300 in the vehicle 1000 according to the first embodiment.

[0040] This application provides a vehicle 1000, which includes a body 100, a window glass assembly 200, and an adhesive 300. The body 100 may be a sheet metal part. The body 100 includes a first door 110, a second door 120, and a side pillar 130. Along the width direction of the vehicle 1000, the first door 110 and the second door 120 are located on the same side of the vehicle 1000. The side pillar 130 is installed between the first door 110 and the second door 120. The window glass assembly 200 is installed on the body 100. The adhesive 300 is located between the window glass assembly 200 and the body 100, and is bonded between the window glass assembly 200 and the body 100 to install the window glass assembly 200 on the body 100. In this embodiment, the window glass assembly 200 serves as a panoramic sunroof. In some other embodiments, the window glass assembly 200 can also be used as a windshield, rear windshield, or triangular window in the vehicle 1000.

[0041] The vehicle window glass assembly 200 includes a window glass A and a warning structure layer 240. The window glass A includes a visible area 200a and a shielding area 200b. The visible area 200a is located in the center of the window glass A. Outside light can enter the interior of the vehicle 1000 through the visible area 200a, and light from inside the vehicle 1000 can also enter the outside environment through the visible area 200a. The shielding area 200b is disposed at the edge of the visible area 200a and surrounds the visible area 200a.

[0042] The vehicle window glass A has an inner surface A1 and an outer surface A2. The inner surface A1 is the surface of the vehicle window glass A facing the interior of the vehicle 1000. The outer surface A2 is the surface of the vehicle window glass A facing the exterior of the vehicle 1000 and is disposed opposite to the inner surface A1. In this embodiment, the vehicle window glass A is laminated glass. The vehicle window glass A may include a first glass 210, a second glass 220, and a first connecting layer 230. The second glass 220 and the first glass 210 are spaced apart and disposed opposite to each other. The first connecting layer 230 is located between the first glass 210 and the second glass 220.

[0043] The first glass 210 is the glass of the vehicle window A near the outside of the vehicle 1000. The first glass 210 includes a first surface 211 and a second surface 212. The first surface 211 is the surface of the first glass 210 facing the outside of the vehicle 1000. The first surface 211 is the outer surface A2. Along the thickness direction of the first glass 210, the second surface 212 is disposed opposite to the first surface 211 and faces the inside of the vehicle 1000. In some embodiments, the thickness of the first glass 210 is greater than or equal to 1.6 mm and less than or equal to 3.5 mm. The visible light transmittance of the first glass 210 can be greater than or equal to 70%, and more preferably greater than or equal to 79%. Preferably, the visible light transmittance of the first glass 210 is greater than or equal to 88%. In this embodiment, the first glass 210 can be an inorganic glass, for example, the first glass 210 is soda-lime glass, borosilicate glass, or aluminosilicate glass. Preferably, the first glass 210 is soda-lime glass. In some other embodiments, the first glass 210 may also be plexiglass, for example, the first glass 210 may be polymethyl methacrylate glass.

[0044] It should be noted that the visible light transmittance involved in this application was tested and calculated according to the ISO 9050 standard. The visible light wavelength range during the testing process was greater than or equal to 380 nm and less than or equal to 780 nm.

[0045] The second glass 220 is the glass of the vehicle window A near the interior of the vehicle 1000, and is located on the side of the second surface 212 opposite to the first surface 211. The second glass 220 includes a third surface 221 and a fourth surface 222. The third surface 221 faces the second surface 212 and is spaced apart from it. Along the thickness direction of the second glass 220, the fourth surface 222 is disposed opposite to the third surface 221 and faces the interior of the vehicle 1000. The fourth surface 222 is the inner surface A1. The thickness of the second glass 220 is greater than or equal to 0.7 mm and less than or equal to 3.5 mm. The visible light transmittance of the second glass 220 is greater than or equal to 25% and less than or equal to 94%. In this embodiment, the second glass 220 can be an inorganic glass, for example, the second glass 220 is made of soda-lime glass, borosilicate glass or aluminosilicate glass. Preferably, the second glass 220 is soda-lime glass. In some other embodiments, the second glass 220 may also be plexiglass, for example, the second glass 220 may be polymethyl methacrylate glass.

[0046] A first connecting layer 230 is located between and bonded to the second surface 212 and the third surface 221 to bond the first glass 210 and the second glass 220 together. The thickness of the first connecting layer 230 is greater than or equal to 0.38 mm and less than or equal to 1.52 mm. The visible light transmittance of the first connecting layer 230 is greater than or equal to 1% and less than or equal to 20%. Preferably, the visible light transmittance of the first connecting layer 230 is greater than or equal to 2% and less than or equal to 10%. In some other embodiments, when the window glass assembly 200 is used as a windshield, rear windshield, or triangular window, the visible light transmittance of the first connecting layer 230 is greater than or equal to 0% and less than or equal to 90%.

[0047] In this embodiment, the first connecting layer 230 may be made of a thermoplastic material. The thermoplastic material may be colored or transparent. For example, the first connecting layer 230 may be made of polyvinyl butyral (PVB). In other embodiments, the first connecting layer 230 may also be made of other materials such as polyvinyl chloride (PVC).

[0048] Please refer to the following: Figure 3 , Figure 3 yes Figure 2 The diagram shows a plan view of the window glass assembly 200.

[0049] A warning structure layer 240 is disposed on the vehicle window glass A and located in the visible area 200a. In this embodiment, the warning structure layer 240 is located on the side of the second glass 220 away from the first glass 210. Specifically, the warning structure layer 240 is disposed on the fourth surface 222 and completely covers the visible area 200a. Exemplarily, the warning structure layer 240 can be formed by coating, screen printing, or magnetron sputtering. The thickness of the warning structure layer 240 is less than or equal to 100 μm. Preferably, the thickness of the warning structure layer 240 is less than or equal to 50 μm. More preferably, the thickness of the warning structure layer 240 is less than or equal to 500 nm.

[0050] In some other embodiments, the warning structure layer 240 may be disposed on any one of the first surface 211, the second surface 212 and the third surface 221, or the warning structure layer 240 may be disposed on at least two of the first surface 211, the second surface 212, the third surface 221 and the fourth surface 222. This application does not limit this.

[0051] The material of the warning structure layer 240 includes a thermochromic material. For example, the thermochromic material may be a color-changing ink. It should be noted that the thermochromic material has different colors and / or visible light transmittance at different temperatures. In other words, the color of the thermochromic material can reversibly change with increasing or decreasing temperature, and can undergo a stepwise change with increasing temperature, so that the color of the warning structure layer 240 changes with temperature, thereby achieving the warning function of the vehicle window glass assembly 200 through the color change of the warning structure layer 240.

[0052] When the temperature of the warning structure layer 240 is within a first temperature range, the color of the warning structure layer 240 is a first color. At this time, the visible light transmittance of the warning structure layer 240 is greater than or equal to 80%. Preferably, the visible light transmittance of the warning structure layer 240 is greater than or equal to 90%. For example, the first color may be transparent, light blue, or white.

[0053] When the temperature of the warning structure layer 240 is within the second temperature range, the color of the warning structure layer 240 is the second color, which is different from the first color. At this time, the visible light transmittance of the warning structure layer 240 is less than or equal to 50%. For example, the second color can be orange. The minimum value of the second temperature range is greater than the maximum value of the first temperature range.

[0054] When the temperature of the warning structure layer 240 is within a third temperature range, the color of the warning structure layer 240 is a third color, which differs from the first and second colors. At this time, the visible light transmittance of the warning structure layer 240 is less than or equal to 20%. For example, the third color can be dark red. The minimum temperature within the third temperature range is greater than the maximum temperature within the second temperature range. For example, the thermochromic material can be a color-changing ink.

[0055] It should be noted that the boundary temperature between the second and first temperature ranges can be the first critical temperature of the thermochromic material, and the boundary temperature between the third and second temperature ranges can be the second critical temperature of the thermochromic material. The first and second critical temperatures can be selected based on the temperature at which a person feels hot when touching the window glass assembly 200. Generally, when the temperature of the window glass assembly 200 exceeds 44°C, a person will feel heat or even burning sensation upon touch. When the temperature of the window glass assembly 200 reaches 47°C, a person will experience the pain of a burn upon touch. When the temperature of the window glass assembly 200 exceeds 50°C, a person will suffer burns upon touch, forming blisters and causing second-degree burns. When the temperature of the window glass assembly 200 reaches 80°C, third-degree burns will occur if the skin is in contact with the window glass assembly 200 for one minute. Furthermore, the temperature at which the window glass assembly 200 feels hot to the touch varies from person to person, mainly depending on individual body temperature, skin sensitivity, and other physiological factors. Based on actual needs, the first and second critical temperatures are selected, and then suitable temperature-sensitive materials are chosen to better enhance the warning function of the window glass assembly 200, prevent passengers from being burned by touching the window glass assembly 200, improve the safety of the vehicle 1000, and enhance the user experience of passengers.

[0056] For example, the first critical temperature of the thermochromic material is 40°C, and the second critical temperature is 50°C. In this case, the first temperature range can be greater than or equal to 0°C and less than 40°C. The second temperature range can be greater than or equal to 40°C and less than 50°C. The third temperature range can be greater than or equal to 50°C and less than or equal to 100°C. When the temperature of the warning structure layer 240 is less than 40°C, the warning structure layer 240 displays a light color. When the temperature of the warning structure layer 240 is greater than or equal to 40°C and less than 50°C, the warning structure layer 240 displays orange. When the temperature of the warning structure layer 240 is greater than or equal to 50°C, the warning structure layer 240 displays dark red.

[0057] A warning structure layer 240, incorporating thermochromic material, is provided. Passengers can quickly identify the temperature of the warning structure layer 240 by its color, thus enabling the window glass assembly 200 to function as a temperature warning and preventing burns from direct contact with the window glass assembly 200 without knowing its temperature. Furthermore, because the warning structure layer 240 is located on the fourth surface 222, which is close to the interior of the vehicle 1000, passengers inside the vehicle 1000 can observe the warning structure layer 240 without looking through the window glass A. This allows for accurate and rapid identification of the color of the warning structure layer 240, improving the warning effect of the window glass assembly 200 and better preventing burns from contact with the window glass assembly 200, thereby enhancing the user experience.

[0058] Please continue reading. Figure 2 In this embodiment, adhesive 300 is bonded between the fourth surface 222 and the vehicle body 100 and is located in the shielded area 200b to install the window glass assembly 200 onto the vehicle body 100.

[0059] Please see Figure 4 , Figure 4 yes Figure 1 The diagram shows a plan view of the window glass assembly 200 in the second embodiment of the vehicle 1000 shown.

[0060] The difference between this embodiment and the first embodiment is that the warning structure layer 240 is disposed in a partial area of ​​the fourth surface 222, partially covering the visible area 200a, and is close to the side pillar 130. Specifically, the visible area 200a includes a first area H and a second area I. The first area H is located on the side of the window glass A near the side pillar 130 and is spaced apart from the shielding area 200b. For example, the area of ​​the first area H is 150mm*150mm. In some other embodiments, the first area H may also be located in the middle of the window glass A. The second area I is disposed around the first area H and connects the first area H and the shielding area 200b.

[0061] The warning structure layer 240 is located in the first zone H, which can reduce the manufacturing cost of the window glass assembly 200 while maintaining its warning function. Furthermore, since the warning structure layer 240 is only located in the first zone H, it will not obstruct the driver's or passengers' observation of the external environment through the second zone I.

[0062] In some other embodiments, the warning structure layer 240 may be disposed on any one of the first surface 211, the second surface 212 and the third surface 221, or the warning structure layer 240 may be disposed on at least two of the first surface 211, the second surface 212, the third surface 221 and the fourth surface 222. This application does not limit this.

[0063] Please see Figure 5 , Figure 5 yes Figure 1 The diagram shows a plan view of the window glass assembly 200 in the vehicle 1000 under a third embodiment.

[0064] The difference between this embodiment and the second embodiment is that the warning structure layer 240 includes a first warning portion h, which is disposed in the first area H. The shape of the first warning portion h includes text and patterns. For example, the shape of the first warning portion h may include a thermometer-style pattern and the word "hot," ensuring that the warning signs of the warning structure layer 240 are clear and conspicuous, facilitating quick observation and identification by drivers and passengers, thereby further improving the warning effect of the vehicle window glass assembly 200. In some other embodiments, the shape of the first warning portion h may include text or patterns; this application does not limit this.

[0065] In some other embodiments, the warning structure layer 240 may also include a second warning portion (not shown), which may be located in the second area I. The second warning portion may completely cover the second area I, or it may partially cover the second area I, which can further enhance the temperature warning effect of the window glass assembly 200 and better prevent occupants from being burned by touching the window glass assembly 200.

[0066] In this embodiment, by setting a first warning portion h on the fourth surface 222 of the second glass 220, the temperature of the warning structure layer 240 can be quickly identified by the color of the first warning portion h, so that the window glass assembly 200 can play a temperature warning role, preventing the driver and passengers from directly touching the window glass assembly 200 when they are unaware of its temperature, thus preventing burns and improving the safety of the vehicle 1000.

[0067] In some other embodiments, the warning structure layer 240 may be disposed on any one of the first surface 211, the second surface 212 and the third surface 221, or the warning structure layer 240 may be disposed on at least two of the first surface 211, the second surface 212, the third surface 221 and the fourth surface 222.

[0068] Please see Figure 6 , Figure 6 yes Figure 1 The diagram shows the structure of the window glass assembly 200 in the vehicle 1000 in the fourth embodiment.

[0069] This embodiment differs from the first embodiment in that the window glass assembly 200 further includes a low-emissivity film layer 250 and an infrared reflective layer 260. The low-emissivity film layer 250 is disposed on the side of the second glass 220 near the interior of the vehicle 1000. Specifically, the low-emissivity film layer 250 is disposed on the fourth surface 222 and covers the warning structure layer 240. The emissivity of the low-emissivity film layer 250 is less than or equal to 0.3. Preferably, the emissivity of the low-emissivity film layer 250 is less than or equal to 0.25. More preferably, the emissivity of the low-emissivity film layer 250 is less than or equal to 0.2. Exemplarily, the low-emissivity film layer 250 is a transparent conductive oxide (TCO) thin film. The low-emissivity film layer 250 includes at least one transparent conductive oxide layer. The low-emissivity film 250 can block the transmission of infrared rays. In winter, it can reduce the heat inside the vehicle 1000 from being radiated to the outside of the vehicle 1000, which helps to keep the interior of the vehicle 1000 warm. In summer, it can also reduce the heat outside the vehicle 1000 from being radiated to the inside of the vehicle 1000, which makes the window glass assembly 200 heat-insulating. It also helps to reduce fuel consumption and save energy.

[0070] An infrared reflective layer 260 is disposed between the first glass 210 and the second glass 220. Specifically, the infrared reflective layer 260 is disposed on the second surface 212. The energy reflectivity of the infrared reflective layer 260 is greater than or equal to 28%. Preferably, the energy reflectivity of the infrared reflective layer 260 is greater than or equal to 40% to ensure that the infrared reflective layer 260 can reflect infrared rays, blocking heat from outside the vehicle 1000 from entering the vehicle 1000, and ensuring that the infrared reflective layer 260 has good heat insulation performance. The infrared reflective layer 260 includes at least one metal layer. In this embodiment, the infrared reflective layer 260 can be made of silver or other metals or metal oxides. Because silver has extremely high infrared reflectivity, it can effectively reduce heat from outside the vehicle 1000 from entering the vehicle 1000, ensuring that the window glass assembly 200 has excellent heat insulation performance, and further improving the comfort of the vehicle 1000. The infrared reflective layer 260 can be formed using physical vapor deposition (PVD), chemical vapor deposition (CVD), or magnetron sputtering processes. In other embodiments, the infrared reflective layer 260 may also be disposed on the first surface 211, the third surface 221, or the fourth surface 222, and this application does not impose any limitations on this.

[0071] It should be noted that the energy reflectivity involved in this application was tested and calculated according to the ISO 9050 standard. During the testing process, the wavelength range of the light was greater than or equal to 300 nm and less than or equal to 2500 nm.

[0072] This embodiment, by adding a low-emissivity film layer 250 and an infrared reflective layer 260, achieves a total energy transmittance of less than or equal to 22.5% for the window glass assembly 200. Preferably, the total energy transmittance of the window glass assembly 200 is less than or equal to 15%. More preferably, the total energy transmittance of the window glass assembly 200 is less than or equal to 13%. The low-emissivity film layer 250 and the infrared reflective layer 260 ensure that the window glass assembly 200 can effectively block and reflect infrared rays, thereby ensuring that the window glass assembly 200 has good heat insulation and thermal insulation performance, further improving the comfort of the vehicle 1000 and the user experience of the occupants. In addition, since the design of the low-emissivity film layer 250 and the infrared reflective layer 260 ensures that the window glass assembly 200 has good heat insulation and thermal insulation performance, the window glass assembly 200 can also achieve heat insulation without the vehicle 1000 having a sunshade. This not only reduces the manufacturing cost of the vehicle 1000 but also saves interior space and improves the user experience of the occupants. At this time, the window glass assembly 200 can be used as a sunroof without a sunshade.

[0073] Please see Figure 7 , Figure 7 yes Figure 1 The diagram shows the structure of the window glass assembly 200 in the vehicle 1000 according to the fifth embodiment.

[0074] The difference between this embodiment and the first embodiment is that the window glass assembly 200 further includes a composite functional layer 270 and a second connecting layer 280. The composite functional layer 270 is located between the first connecting layer 230 and the second glass 220, and the second connecting layer 280 is located between the composite functional layer 270 and the second glass 220. Furthermore, the first connecting layer 230 is located between the first glass 210 and the composite functional layer 270. Specifically, the composite functional layer 270 includes a fifth surface 271 and a sixth surface 272. The fifth surface 271 is disposed opposite to the second surface 212. Along the thickness direction of the window glass assembly 200, the sixth surface 272 is disposed opposite to the fifth surface 271 and is located on the side of the third surface 221 away from the fourth surface 222. The composite functional layer 270 can be made of polymer dispersed liquid crystal (PDLC) or electrochromic (EC) materials, enabling the window glass assembly 200 to have dimming, ambient lighting, or sound insulation functions, thereby increasing the multifunctionality of the window glass assembly 200.

[0075] The second connecting layer 280 is located between the sixth surface 272 and the third surface 221, and is bonded between the sixth surface 272 and the third surface 221 to bond the composite functional layer 270 and the second glass 220 together. The material of the second connecting layer 280 is the same as that of the first connecting layer 230 in the first embodiment; please refer to the preceding description of the material of the first connecting layer 230, which will not be repeated here.

[0076] The first connecting layer 230 is located between the second surface 212 and the fifth surface 271, and is bonded between the second surface 212 and the fifth surface 271 to bond the composite functional layer 270 and the first glass 210 together.

[0077] In this embodiment, when a composite functional layer 270 is added to the window glass assembly 200, the window glass assembly 200 includes two connecting layers, namely, the window glass assembly 200 includes a first connecting layer 230 and a second connecting layer 280. In some other embodiments, when the window glass assembly 200 has two or more functional layers, the connecting layers may have three or more layers. The materials of the connecting layers may be the same as the material of the first connecting layer 230.

[0078] Please see Figure 8 and Figure 9 , Figure 8 yes Figure 1 The diagram shows the structure of the window glass assembly 200 in the vehicle 1000 according to the sixth embodiment. Figure 9 yes Figure 8 The diagram shows a plan view of the window glass assembly 200.

[0079] The difference between this embodiment and the fourth embodiment is that the low-emissivity film layer 250 is disposed on the fourth surface 222, located in the visible area 200a, and covers the visible area 200a. In some other embodiments, the low-emissivity film layer 250 may simultaneously cover both the shielding area 200b and the visible area 200a.

[0080] In vehicle window glass A, the visible area 200a includes a first area H, a second area I, and a third area J. The first area H is spaced apart from the obscured area 200b. The second area I surrounds the first area I and connects the first area H and the obscured area 200b. The third area J surrounds the second area I and connects the second area I and the obscured area 200b.

[0081] A warning structure layer 240 is disposed on the third surface 221. The warning structure layer 240 includes a first warning portion h, a second warning portion i, and a third warning portion j. The first warning portion h is disposed in a first region H. The second warning portion i is disposed in a second region I and covers the second region I. The third warning portion j is disposed in a third region J. The material of the first warning portion h includes a thermochromic material, the material of the second warning portion i includes a thermochromic material, and the material of the third warning portion j includes a photosensitive material and a thermochromic material. For example, the photosensitive material can be photosensitive ink. It should be noted that the photosensitive material does not change color with temperature changes and is invisible or dimly colored under natural light or ordinary white light, but can display color under light of a specific wavelength. The shape of the third warning portion j includes an ambient pattern. For example, the ambient pattern can include a moon shape, a heart shape, an anime character, a natural landscape, or an oil painting, etc.

[0082] In some other embodiments, the warning structure layer 240 may be disposed on any one of the first surface 211, the second surface 212 and the fourth surface 222, or the warning structure layer 240 may be disposed on at least two of the first surface 211, the second surface 212, the third surface 221 and the fourth surface 222. This application does not limit this.

[0083] In this embodiment, the window glass assembly 200 further includes a light guide 291, a light source 292, and a protective cover 293. The light guide 291 is disposed on the inner surface A1, that is, on the fourth surface 222, and located in the shielding area 200b, and on the side of the adhesive 300 near the visible area 200a. There are two light guides 291. Along the width direction of the window glass assembly 200, the two light guides 291 are respectively located on both sides of the second glass 220.

[0084] The light source 292 is disposed on the surface of the light guide 291 opposite to the window glass A and located in the shielding area 200b, and is electrically connected to the power supply device inside the vehicle 1000. A protective cover 293 is mounted on the fourth surface 222 and covers the light source 292 and the light guide 291 to shield and protect the light source 202 and the light guide 291. Exemplarily, the protective cover 293 is mounted on the fourth surface 222 by adhesive bonding.

[0085] When the vehicle 1000 is used during the day, the light source 292 can be de-energized. When the temperature of the warning structure layer 240 changes, the color of the thermochromic material in the warning structure layer 240 changes, thus changing the color of the warning structure layer 240 to provide a temperature warning function for the window glass assembly 200. When the vehicle 1000 is used at night, the light source 292 is energized and emits light. The light is refracted and propagated within the window glass assembly 200 through the light guide 291. When the light shines on the third warning part j, the photosensitive material in the third warning part j displays a color to show an ambient pattern, thereby enhancing the ambiance of the vehicle 1000. At this time, the visible light transmittance of the window glass assembly 200 is greater than or equal to 85%, preferably greater than or equal to 90%. In this embodiment, the window glass assembly 200 not only provides a temperature warning function but also enhances the ambiance inside the vehicle 1000, further improving the user experience for drivers and passengers.

[0086] Please see Figure 10 , Figure 10 yes Figure 1 A plan view of the window glass assembly 200 in the vehicle 1000 shown in the seventh embodiment.

[0087] The difference between this embodiment and the sixth embodiment is that the warning structure layer 240 does not include the second warning part i, and the third warning part j in the warning structure layer 240 is also provided in the second area I. While giving full play to the warning function of the warning structure layer 240, the area of ​​the ambient pattern is increased, thereby improving the user experience of drivers and passengers.

[0088] Please see Figure 11 , Figure 11 yes Figure 1 A plan view of the window glass assembly 200 in the vehicle 1000 shown in the eighth embodiment.

[0089] The difference between this embodiment and the seventh embodiment is that the warning structure layer 240 does not include the first warning part h, and the third warning part j in the warning structure layer 240 is also provided in the first area H. While giving full play to the warning function of the warning structure layer 240, the area of ​​the ambient pattern is further increased, improving the user experience of drivers and passengers.

[0090] In some other embodiments, the warning structure layer 240 may not include the third warning portion j, while the window glass assembly 200 may include an ambient pattern layer (not shown). Along the thickness direction of the window glass assembly 200, the ambient pattern layer may be disposed on the surface of the warning structure layer 240 and cover the visible area 200a. The material of the ambient pattern layer may include a photosensitive material.

[0091] Please see Figure 12 , Figure 12 yes Figure 1 The diagram shows the structure of the window glass assembly 200 in the vehicle 1000 according to the ninth embodiment.

[0092] The difference between this embodiment and the first embodiment is that the vehicle window glass A is a single-layer glass, and the warning structure layer 240 is disposed on the inner surface A1 of the vehicle window glass A. For example, the vehicle window glass A can be tempered glass.

[0093] This application presents tests on the vehicle window glass assembly 200 according to the first, third, fourth, eighth, and ninth embodiments. By applying different temperatures to the vehicle window glass assembly 200 under different embodiments, the warning performance of the vehicle window glass assembly 200 was observed. The test results all indicate that the vehicle window glass assembly 200 has a good warning effect. The experimental conditions and test results are shown in Table 1.

[0094] Table 1 shows the experimental conditions and test results for the vehicle window glass assembly 200 under different implementation methods.

[0095]

[0096] This application incorporates a warning structure layer 240 within the vehicle window glass assembly 200. This warning structure layer 240 is made of a thermochromic material, and its color changes with temperature. The vehicle window glass assembly 200 serves as a temperature warning, allowing occupants to perceive the temperature of the window glass assembly 200 without touching it. This avoids burns caused by direct contact with the window glass assembly 200, improving vehicle safety and enhancing the user experience. Furthermore, a low-emissivity film layer 250 can be added to the window glass assembly 200, providing thermal insulation properties. Additionally, an infrared reflective layer 260 can be added to the window glass assembly 200 to further enhance its thermal insulation effect, thereby further improving vehicle comfort and the user experience.
