Description

Technical Field

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

[0002] Existing vehicle windows often combine imaging display and electric heating functions. This not only allows drivers and passengers to access real-time vehicle information during daily driving but also defrosts and defogs the windows, facilitating observation of the external environment. The electric heating function is typically achieved through a busbar and a conductive film layer. However, both the busbar and the conductive film layer can interfere with the window's imaging display function, negatively impacting image quality and reducing the driving experience for passengers. Summary of the Invention

[0005] The vehicle window glass includes a first glass, a second glass, a first shielding layer, a conductive film layer, a first electrical connector, a second electrical connector, and a second shielding layer. The second glass is located on the side of the first glass facing the interior of the vehicle and is spaced apart from the first glass.

[0006] The first shielding layer, the conductive film layer, the first electrical connector, and the second electrical connector are all disposed between the first glass and the second glass.

[0010] Wherein, the incident light reflectivity of the display area is greater than or equal to 10%, or the incident light reflectivity of the display area is greater than or equal to 20%, or the incident light reflectivity of the display area is greater than or equal to 30%.

[0011] At least a portion of the conductive film layer is located in the display area.

[0012] The vehicle window glass further includes a reflective layer located on the side of the second shielding layer opposite to the second glass. The reflective layer is used to reflect incident light, wherein the incident light includes P-polarized light.

[0013] The reflective layer has a reflectivity of at least 10% for P-polarized light incident at an incident angle of 55°.

[0014] The vehicle window glass also includes a third glass, which is located in the display area and is disposed on the side of the second shielding layer away from the second glass, and is spaced apart from the second glass. The reflective layer is disposed on the surface of the third glass away from the second shielding layer, or the reflective layer is disposed between the third glass and the second shielding layer.

This prevents visible light from reflecting off the conductive film layer and causing ghosting. The second shielding layer also shields the second electrical connector and the conductive film layer, reducing their impact on the imaging display. Simultaneously, the second shielding layer serves as a display background, enhancing the contrast between the displayed image and the background, resulting in a clearer image. This further improves the imaging display effect of the vehicle window glass, enhancing the driving experience for passengers and improving vehicle safety and comfort. Attached Figure Description

[0037] The vehicle window 200 has a viewing area 200a and a shielding area 200b. The viewing area 200a is located in the center of the vehicle window 200. External light can enter the vehicle 1000 through the viewing area 200a, and light from inside the vehicle 1000 can also enter the external environment through the viewing area 200a. The shielding area 200b is located at the edge of the vehicle window 200 and surrounds the viewing area 200a. The shielding area 200b includes a display area H. Along the height of the vehicle window 200, the display area H is located to one side of the viewing area 200a. The display area H is used to reflect incident light to form a displayed image.

Specifically, the first area 200c is located at the top of the window glass 200, and the second area 200d is located at the bottom of the window glass 200. The second area 200d includes a display area H. Along the length of the window glass 200, the third area 200e and the fourth area 200f are located on opposite sides of the viewing area 200a, and both are connected between the first area 200c and the second area 200d.

[0039] It should be noted that the directional terms such as "bottom" and "top" used in this application are for reference only. Figure 2 The description of the orientation shown, with the positive Y-axis direction as "top" and the negative Y-axis direction as "bottom", is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Please refer to the following: Figure 3 , Figure 3 yes Figure 2 The diagram shows a cross-sectional view of the car window glass 200 cut along point AA.

[0041] The vehicle window glass 200 may include a first glass 210, a second glass 220, an interlayer 241, a third glass 230, and a first connecting layer 245. Along the thickness direction of the vehicle window glass 200, the second glass 220 and the first glass 210 are spaced apart, and the third glass 230 and the second glass 220 are spaced apart. The interlayer 241 is located between the first glass 210 and the second glass 220. The first connecting layer 245 is located between the second glass 220 and the third glass 230.

The first surface 211 is the surface of the first glass 210 facing outwards from the vehicle 1000. Along the thickness direction of the first glass 210, the second surface 212 is disposed opposite to the first surface 211 and faces inwards from the vehicle 1000. For example, the first glass 210 can be a single pane of glass, a double-layered laminated glass, or an insulated glass unit.

[0043] The second glass 220 is located on the side of the first glass 210 facing the interior of the vehicle 1000, and is also located on the side of the second surface 212 facing away from the first surface 211, and is spaced apart from the second surface 212. 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 the second surface 212. 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. For example, the second glass 220 can be a single pane of glass, a double-layered laminated glass, or an insulated glass unit.

[0044] An intermediate layer 241 is located between the first glass 210 and the second glass 220, and is bonded between the second surface 212 and the third surface 221 to bond the first glass 210 and the second glass 220 together. The intermediate layer 241 has a visible light transmittance greater than or equal to 85% to ensure high visible light transmittance, allowing light to pass through without affecting the occupants' observation of the external environment. Furthermore, the intermediate layer 241 has a haze degree less than or equal to 1% to ensure low haze, preventing haze from affecting the light transmittance of the window glass 200 and thus ensuring the transparency of the window glass 200. Preferably, the haze degree of the intermediate layer 241 is less than or equal to 0.4%.

[0045] The material of the intermediate layer 241 may include a thermoplastic material. Thermoplastic materials include, but are not limited to, one or more of polyvinyl butyral (PVB), ethylene-vinyl acetate copolymer (EVA), and optically clear resin (OCR). In some other embodiments, the material of the intermediate layer 241 may also include a thermosetting material. Thermosetting materials include, but are not limited to, one or more of optically clear adhesive (OCA), liquid optically clear adhesive (LOCA), and optically clear resin (OCR).

[0046] The third glass 230 is located in the shielding area 200b and in the display area H. The third glass 230 is located on the side of the second glass 220 away from the first glass 210 and is spaced apart from the second glass 220. The third glass 230 includes a fifth surface 231 and a sixth surface 232. The fifth surface 231 faces the fourth surface 222 and is spaced apart from the fourth surface 222. Along the thickness direction of the third glass 230, the sixth surface 232 is disposed opposite to the fifth surface 231 and faces the interior of the vehicle 1000.

[0047] The first connecting layer 245 is located between the second glass 220 and the third glass 230, and is bonded between the fourth surface 222 and the fifth surface 231 to bond the second glass 220 and the third glass 230 together. The visible light transmittance of the first connecting layer 245 is greater than or equal to 85% to ensure high visible light transmittance, allowing light to pass through without affecting the occupants' observation of the external environment. Furthermore, the haze of the first connecting layer 245 is less than or equal to 1% to ensure low haze, preventing haze from affecting light transmission and thus ensuring the light transmittance of the first connecting layer 245. Preferably, the haze of the first connecting layer 245 is less than or equal to 0.4%. In this embodiment, the material of the first connecting layer 245 can refer to the material of the intermediate layer 241 mentioned above, and will not be repeated here.

[0048] The vehicle window glass 200 also includes a first shielding layer 251, a conductive film layer 260, a first electrical connector 271, a second electrical connector 275, a second shielding layer 255, and a reflective layer 280. The first shielding layer 251, the conductive film layer 260, the first electrical connector 271, and the second electrical connector 275 are all disposed between the first glass 210 and the second glass 220. Specifically, the first shielding layer 251, the conductive film layer 260, the first electrical connector 271, and the second electrical connector 275 are all disposed between the second surface 212 and the third surface 221. Specifically, the shielding area 200b is provided with the first shielding layer 251. The first shielding layer 251 is disposed on the second surface 212. The material of the first shielding layer 251 includes opaque materials such as ink. For example, the first shielding layer 251 can be formed on the second surface 212 by printing. The first shielding layer 251 has a visible light transmittance of less than or equal to 0.05% to block visible light from passing through, thus preventing visible light from affecting the display imaging effect. It can also improve the contrast between the displayed image and the display background, making the image clearer. In some other embodiments, the first shielding layer 251 may also be disposed on the third surface 221, which is not a limitation of this application.

[0049] The conductive film layer 260 is at least partially located in the transparent area 200a and the shielding area 200b, and at least partially located in the display area H. The area containing the conductive film layer 260 is the electrically heated area J. In some embodiments, the electrically heated area J includes at least a portion of the transparent area 200a and the shielding area 200b. When the conductive film layer 260 is energized, it can heat the electrically heated area J to defrost and clear fog, allowing occupants to observe the external environment of the vehicle.

[0050] A conductive film layer 260 is disposed on the surface of the first glass 210 facing the second glass 220, and covers at least a portion of the first shielding layer 251. Specifically, the conductive film layer 260 is disposed on the second surface 212, and covers at least a portion of the surface of the first shielding layer 251 facing away from the second surface 212. The conductive film layer 260 can be formed by processes such as magnetron sputtering or chemical vapor deposition. In some other embodiments, the conductive film layer 260 may also be disposed on the third surface 221, which is not a limitation of this application.

[0051] In this embodiment, the conductive film layer 260 includes at least one of a metal layer, a metal alloy layer, and a metal oxide layer. Specifically, in some other embodiments, the conductive film layer 260 includes a metal layer. There may be one or more metal layers, and this application is not limited in this regard. The material of the metal layer includes at least one of gold (Au), silver (Ag), copper (Cu), aluminum (Al), and molybdenum (Mo). For example, when the material of the metal layer includes a silver layer, the conductive film layer 260 may include one or more silver layers. In some other embodiments, the conductive film layer 260 includes a metal alloy layer. The material of the metal alloy layer includes a silver alloy. In some other embodiments, the conductive film layer 260 includes a metal oxide layer. The conductive film layer 260 may include an indium tin oxide (ITO), an antimony tin oxide (ATO), an aluminum zinc oxide (AZO), or a fluorine-doped tin oxide (FTO), etc. Accordingly, the materials for the metal oxide layer include at least one of indium tin oxide, tin-zinc oxide, fluorine-doped tin dioxide, aluminum-doped tin dioxide, gallium-doped tin dioxide, boron-doped tin dioxide, and antimony-doped tin oxide. It should be noted that indium tin oxide (ITO) is a transparent conductive film composed of indium oxide (In₂O₃) and tin oxide (SnO₂), while antimony tin oxide (ATO) is a composite oxide film composed of antimony (Sb) and tin (Sn). Fluorine-doped tin oxide (FTO) is a transparent conductive film composed of N-type semiconductor materials.

[0052] Both the first electrical contact 271 and the second electrical contact 275 are located in the shielding area 200b. Along the thickness direction of the conductive film layer 260, both the first electrical contact 271 and the second electrical contact 275 are disposed on the surface of the conductive film layer 260 facing the second glass 220, and are both electrically connected to the conductive film layer 260. The first electrical contact 271 and the second electrical contact 275 are spaced apart. Along the height direction of the window glass 200, the first electrical contact 271 and the second electrical contact 275 are located on opposite sides of the viewing area 200a. Specifically, the first electrical contact 271 is located in the first area 200c and is electrically connected to the positive terminal of the external power supply. The second electrical contact 275 is located in the second area 200d, and at least partially located in the display area H, and is electrically connected to the negative terminal of the external power supply. The supply voltage of the external power supply is greater than or equal to 12V and less than or equal to 60V.

[0053] In this embodiment, the first electrical connector 271 and the second electrical connector 275 can be busbars. The material of the busbars includes silver paste, which is white. Both the first electrical connector 271 and the second electrical connector 275 can be attached to the surface of the conductive film layer 260 by a printing process. In some other embodiments, the first electrical connector 271 can be electrically connected to the negative terminal of an external power supply, and the second electrical connector 275 can be electrically connected to the positive terminal of an external power supply.

[0054] The arrangement of the first electrical connector 271, the second electrical connector 275, and the conductive film layer 260 enables the window glass 200 to have a heating function, thereby achieving the function of defrosting and defogging the window glass 200. Specifically, after the external power supply is turned on, the current is transmitted through the first electrical connector 271 to the conductive film layer 260, then to the second electrical connector 275, and then back to the external power supply. During the current path, the conductive film layer 260 generates heat due to resistance, and heats the window glass 200 in the electric heating zone J. The conductive film layer 260 enables the window glass 200 to have a heat output of at least 350 W / m². 2 The heating power density is high. As the temperature of the window glass 200 rises, the frost or fog on the surface of the window glass 200 evaporates or melts, thereby clearing the frost and fog from the window glass 200, ensuring the clarity of the window glass 200, improving the driving experience for passengers, and enhancing the safety of the vehicle 1000. Furthermore, the first electrical connector 271 and the second electrical connector 275 are distributed on opposite sides of the viewing area 200a, ensuring that the first electrical connector 271 and the second electrical connector 275 uniformly transmit current to the conductive film layer 260, thereby uniformly heating the window glass 200 and improving the defrosting and defogging effect of the window glass 200.

[0055] The display area H is provided with a second shielding layer 255. The second shielding layer 255 is located on the side of the second glass 220 opposite to the first glass 210. Specifically, the second shielding layer 255 is disposed between the second glass 220 and the third glass 230, and is located on the side of the first connecting layer 245 opposite to the third glass 230, and is disposed on the surface of the first connecting layer 245 away from the third glass 230. Specifically, the second shielding layer 255 is disposed on the fourth surface 222. In this embodiment, the material of the second shielding layer 255 includes an opaque material such as ink. For example, the second shielding layer 255 can be formed on the fourth surface 222 by printing. The second shielding layer 255 has a visible light transmittance of less than or equal to 0.05%, which further blocks visible light from passing through the second glass 220 to the conductive film layer 260 in the display area H. This avoids visible light reflection at the conductive film layer 260, thus reducing the impact of the conductive film layer 260 on the display imaging function of the display area H. It also shields the second electrical contact 275 and the conductive film layer 260, further reducing their impact on the imaging display of the display area H. Furthermore, it serves as a background for the imaging display, further improving the contrast between the displayed image and the background, making the image clearer. In some other embodiments, the second shielding layer 255 may also be disposed on the fifth surface 231; this application does not limit this.

[0056] A reflective layer 280 is disposed on the side of the third glass 230 opposite to the second glass 220, and on the surface of the third glass 230 opposite to the second shielding layer 255. Specifically, the reflective layer 280 is disposed on the sixth surface 232, located in the display area H, and is used to reflect incident light. The incident light reflectivity of the reflective layer 280 is greater than or equal to 10%, or greater than or equal to 15%. Preferably, the incident light reflectivity of the reflective layer 280 is greater than or equal to 20%, or greater than or equal to 25%. More preferably, the incident light reflectivity of the reflective layer 280 is greater than or equal to 30%, to ensure that the reflective layer 280 has a high incident light reflectivity and that the incident light reflectivity of the display area H is greater than or equal to 10%, or greater than or equal to 20%, or greater than or equal to 30%, which effectively reflects the incident light. The incident light may include P-polarized light, which may be emitted by an external image source. It should be noted that the reflective layer 280 has a reflectivity of at least 10% for P-polarized light incident at an angle of 55°. For example, the reflective layer 280 may be a nano-reflective film, a reflective film, or an anti-reflective film.

[0057] In this embodiment, the vehicle window glass 200 includes a display function layer B. The display function layer B includes a first shielding layer 251, a second shielding layer 255, and a reflective layer 280. The display function layer B is used to receive and reflect incident light. An external image source is installed on the vehicle body 100 and located inside the vehicle 1000. For example, the external image source may be a projector or a display screen.

[0058] When imaging is displayed on the vehicle window glass 200, the incident light emitted from the external image source projects the image onto the display area H of the vehicle window glass 200. The incident light illuminates the sixth surface 232, and under the action of the reflective layer 280, the incident light undergoes specular reflection, forming a virtual image on the backward extension line of the reflected light for observation by the driver and passengers. Both the first shielding layer 251 and the second shielding layer 255 can block ambient light from entering the vehicle 1000 through the window glass 200, thereby reducing interference from ambient light on the reflected imaging of the external image source and improving the quality of the reflected imaging. Furthermore, both the first shielding layer 251 and the second shielding layer 255 can also serve as a display background, improving the contrast between the displayed image and the background, making the image clearer. The reflective layer 280 has a high P-polarized light reflectivity, effectively reflecting P-polarized light and further improving the quality of the reflected imaging.

[0059] Please see Figure 4 , Figure 4 yes Figure 1 A cross-sectional structural diagram of the window glass 200 in the vehicle 1000 shown in the second embodiment.

[0060] The difference between this embodiment and the first embodiment is that the reflective layer 280 is located between the third glass 230 and the second shielding layer 255, and between the first connecting layer 245 and the third glass 230. Specifically, the reflective layer 280 is disposed on the surface of the third glass 230 facing the second shielding layer 255, that is, the reflective layer 280 is disposed on the fifth surface 231. In this case, the thickness of the third glass 230 is less than or equal to 1.1 mm to avoid ghosting during the imaging display process, thereby improving the clarity of the image of the window glass 200, enhancing the driving experience of the occupants, and improving the safety and comfort of the vehicle 1000. Specifically, when the incident light emitted from the external image source projects the image onto the display area H of the window glass 200, the incident light first illuminates the sixth surface 232, and a portion of the incident light undergoes specular reflection on the sixth surface 232 to form a first virtual image. Another portion of the incident light passes through the sixth surface 232 and is refracted within the third glass 230. The refracted light undergoes specular reflection under the action of the reflective layer 280, forming a second virtual image. The first and second virtual images are superimposed to form a ghost image. When the thickness of the third glass 230 decreases, the ghost image becomes weaker, which can improve image clarity.

[0061] In some other embodiments, the reflective layer 280 may also be disposed on the fourth surface 222 and at least partially cover the second shielding layer 255. In this case, the sum of the thickness of the first connecting layer 245 and the thickness of the third glass 230 is less than or equal to 1.1 mm to avoid ghosting during the imaging display process, thereby improving the clarity of the image of the vehicle window glass 200.

[0062] Please see Figure 5 , Figure 5 yes Figure 1 A cross-sectional structural diagram of the window glass 200 in the vehicle 1000 shown in the third embodiment.

[0063] The difference between this embodiment and the second embodiment is that the window glass 200 further includes a second connecting layer 248, which is located between the first connecting layer 245 and the third glass 230, and is connected to the third glass 230. A reflective layer 280 is located on the side of the second connecting layer 248 facing away from the third glass 230, and is disposed on the surface of the first connecting layer 245 facing the third glass 230; that is, the reflective layer 280 is located between the second connecting layer 248 and the first connecting layer 245. In this case, the sum of the thickness of the second connecting layer 248 and the thickness of the third glass 230 is less than or equal to 1.1 mm to avoid ghosting during the imaging process, thereby improving the clarity of the image formed by the window glass 200, enhancing the driving experience for passengers, and improving the safety and comfort of the vehicle 1000.

[0064] Please see Figure 6 and Figure 7 , Figure 6 yes Figure 1 The diagram shows a plan view of the vehicle window glass 200 in the fourth embodiment of the vehicle 1000 shown. Figure 7 yes Figure 6 The diagram shows a cross-sectional view of the car window glass 200 cut along BB.

[0065] The difference between this embodiment and the third embodiment is that the material of the first shielding layer 251 includes conductive materials such as conductive ink, which enables the first shielding layer 251 to have conductive properties, allowing current to pass through and conduct the current to the conductive film layer 260. For example, the first shielding layer 251 is made of conductive ink. In this embodiment, the first shielding layer 251 includes a first shielding portion 251a, a second shielding portion 251b, a third shielding portion 251c, and a fourth shielding portion 251d. The first shielding portion 251a is located in the first region 200c, the second shielding portion is located in the second region 200d and is spaced apart from the first shielding portion 251a, and the third shielding portion 251c is located in the third region 200e and is spaced apart from both the first shielding portion 251a and the second shielding portion 251b. The fourth shielding portion 251d is located in the fourth zone 200f and is spaced apart from the third shielding portion 251c, as well as spaced apart from the first shielding portion 251a and the second shielding portion 251b, to prevent the first shielding layer 251 from forming a circuit on its own after being energized.

[0066] In this embodiment, the first electrical contact 271 is located in the first region 200c and is electrically connected to the first shielding portion 251a. Multiple first electrical contacts 271 are arranged at intervals. For example, there are two first electrical contacts 271, both of which are positive terminals. The second electrical contact 275 is located in the second region 200d, spaced from the display region H, and is electrically connected to the second shielding portion 251b. Multiple second electrical contacts 275 are arranged at intervals. For example, there are two second electrical contacts 275, both of which are negative terminals. In some other embodiments, both the first electrical contact 271 and the second electrical contact 275 may be located in the display region H; this application is not limited to this. In some other embodiments, the first electrical contact 271 may also be located in the third region 200e and electrically connected to the third shielding portion 251c. The second electrical contact 275 may also be located in the fourth zone 200f and electrically connected to the fourth shielding portion 251d, which is not a limitation of this application.

[0067] In this embodiment, the first electrical connector 271, the first shielding layer 251, the conductive film layer 260, the second electrical connector 275, and the external power supply form a complete current loop. After the external power supply is powered on, the current flows through the first electrical connector 271 to the first shielding portion 251a, and is transmitted to the conductive film layer 260, then to the second shielding portion 251b, and flows back to the external power supply through the second electrical connector 275. During the current path, the conductive film layer 260 generates heat due to resistance, and heats the window glass 200 in the electric heating zone J, thereby enabling the window glass 200 to have the function of heating, defrosting, and defogging, ensuring the clarity of the window glass 200 and improving the safety of the vehicle 1000. It should be noted that the third shielding portion 251c and the fourth shielding portion 251d are both spaced apart from the first shielding portion 251a and the second shielding portion 251b. This can block the current loop formed in the first shielding layer 251, ensuring that the current flows through the first shielding layer 251 to the conductive film layer 260, thereby ensuring that the conductive film layer 260 generates heat to heat the window glass 200.

[0068] In some other embodiments, the third shielding portion 251c may include two first sub-shielding portions, which are respectively connected to the first shielding portion 251a and the second shielding portion 251b and are spaced apart from each other. And / or, the fourth shielding portion 251d may also include two second sub-shielding portions, which are respectively connected to the first shielding portion 251a and the second shielding portion 251b and are spaced apart from each other. Alternatively, the materials of the third shielding portion 251c and the fourth shielding portion 251d may not include conductive materials. In this case, the third shielding portion 251c and the fourth shielding portion 251d may not be spaced apart from the first shielding portion 251a and the second shielding portion 251b.

[0069] This application provides a second shielding layer 255 to further block visible light from entering the second glass 220 and reaching the conductive film layer 260 within the display area H. This prevents visible light from reflecting off the conductive film layer 260 and causing ghosting. The second shielding layer 255 also shields the second electrical connector 275 and the conductive film layer 260, reducing their impact on the image display. Simultaneously, the second shielding layer 255 can also serve as a display background, improving the contrast between the displayed image and the background, making the image clearer. Furthermore, by providing a third glass 230 and a reflective layer 280, reflection occurs on the surface of the third glass 230, preventing visible light from entering the second glass 220 within the display area H. This ensures that neither the second electrical connector 275 nor the conductive film layer 260 affects the imaging of the window glass 200 in the display area H, further improving the imaging display effect of the window glass 200, enhancing the driving experience for passengers, and improving the safety and comfort of the vehicle 1000.
