[0002] The vehicle window glass of the existing vehicle is usually provided with a light-adjusting film in the sun-shading area to change the light brightness of the sun-shading area. When the light is too strong, the light-adjusting film is in a closed state, but maintains its sun-shading function to prevent the driver from visual fatigue. When the light is insufficient, the light-adjusting function of the light-adjusting film is opened to improve the brightness of the driver's field of view and enhance the visibility of the vehicle window glass. However, due to the relatively hard material structure of the light-adjusting film, the light-adjusting film will wrinkle when assembled on the vehicle window glass, resulting in poor appearance of the vehicle window glass and reducing the driving experience of the driver and the passenger.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Please refer to Figure 1 , Figure 1 A structure schematic view of a vehicle 1000 provided by the embodiments of the present application is shown in the figure.

[0021] The embodiments of the present application provide a vehicle 1000, which comprises a vehicle body 100 and a vehicle window glass assembly B. The vehicle body 100 can be a sheet metal part. The vehicle window glass assembly B is installed on the vehicle body 100. In the embodiments, the vehicle window glass 200 is used as a front windshield. In other embodiments, the vehicle window glass 200 can also be used as a rear windshield or other glass of the vehicle 1000.

[0022] Please refer to Figure 2 , Figure 2 A structure schematic view of a vehicle 1000 provided by the embodiments of the present application is shown in the figure. Figure 1 A structure schematic view of a vehicle 1000 provided by the embodiments of the present application is shown in the figure.

[0023] The vehicle window glass assembly B includes a vehicle window glass 200. The length direction of the vehicle window glass 200 is defined as the X-axis, the width direction as the Y-axis, and the thickness direction as the Z-axis. The X, Y, and Z axes are mutually perpendicular. Specifically, the vehicle window glass 200 has a viewing area 200a and a non-viewable area 200b. The viewing area 200a is located in the center of the vehicle window glass 200. External light can enter the vehicle 1000 through the viewing area 200a, and internal light can also enter the external environment through the viewing area 200a. The viewing area 200a includes area A 200c and area B 200d. The driver and passengers primarily observe the external environment of the vehicle 1000 through area A 200c. Area B 200d is positioned around area A 200c. The driver and passengers can also observe the external environment of the vehicle 1000 through area B 200d. The visible light transmittance of area A is greater than that of area B, ensuring that the driver's side window 200 has higher visible light transmittance and guarantees driving safety. Areas A 200c and B 200d can be classified according to GB9656-2021 "Technical Specifications for Motor Vehicle Glass Safety", or according to the "ECE R43" standard.

[0024] The non-visible zone 200b is located at the edge of the window glass 200, surrounds the visible zone 200a, and is spaced apart from zone B 200d. The non-visible zone 200b includes a first functional area 200f, a second functional area 200h, and a shielding area 200k. Both the first functional area 200f and the second functional area 200h are spaced apart from the visible zone 200a, located at the top of the visible zone 200a, and are both transparent and visible, and are also used to transmit optical signals. For example, the first functional area 200f can be a camera functional area. A camera or video camera can identify the external environment of the vehicle 1000 through the first functional area 200f. The second functional area 200h is spaced apart from the first functional area 200f. For example, the second functional area 200h can be a sensor functional area. Sensors and other sensing instruments can identify the external environment through the second functional area 200h, thereby enabling automatic control of the operation of windshield wipers or other functional components.

[0025] The shielding area 200k is disposed around the visible area 200a and around the first functional area 200f and the second functional area 200h. It should be noted that the window glass assembly B may also include a shielding layer (not shown). The shielding layer is disposed on the window glass 200, located in the non-visible area 200b, and covers the shielding area 200k. The shielding layer can reduce the exchange of sightlines between the inside and outside of the vehicle, protect the privacy of the occupants inside the vehicle, and improve the aesthetics of the window glass assembly B. For example, the material of the shielding layer includes ink.

[0026] The vehicle window glass 200 also has a sunshade area 200e. The sunshade area 200e includes a partially shaded area 200k and a partially visible area 200a. The sunshade area 200e is also spaced apart from the first functional area 200f and the second functional area 200h. In this embodiment, the sunshade area 200e is located at the top of the vehicle window glass 200. Specifically, the sunshade area 200e also has a boundary line T. The boundary line T is the edge line of the sunshade area 200e near the bottom of the vehicle window glass 200, and is the horizontal line where the edge line of area B 200d near the top of the vehicle window glass 200 is located. That is, the boundary line T is the horizontal line where the edge line of area B 200d near the top of the vehicle window glass 200 is located. The area near the top of the window glass 200 along the boundary line T is the sunshade area 200e. That is, along the width of the window glass 200, the sunshade area 200e is located at the top of area B. The sunshade area 200e, the first functional area 200f, and the second functional area 200h are all spaced apart. The boundary line T is parallel to the length of the window glass 200. The area of ​​the sunshade area 200e can be one-third the sum of the areas of the visible area 200a and the non-visible area 200b. In some other embodiments, the sunshade area 200e can also be defined according to the Federal Motor Vehicle Safety Standard (205) (FMVSS 205) or according to the American National Standards Institute standard ANSI Z26.1.

[0027] 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.

[0028] Please refer to the following: Figure 3 , Figure 3 yes Figure 2 The diagram shows a cross-sectional view of the vehicle window glass 200.

[0029] In this embodiment, the vehicle window glass 200 is laminated glass. Specifically, the vehicle window glass 200 includes a first glass 210, a second glass 220, and a connecting layer 225. Along the thickness direction of the vehicle window glass 200, the second glass 220 and the first glass 210 are spaced apart and disposed opposite to each other. The first glass 210 and the second glass 220 are connected by the connecting layer 225.

[0030] The first glass 210 is the glass of the vehicle window 200 facing outwards from 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 outwards from the vehicle 1000. The second surface 212 is the surface of the first glass 210 facing outwards from the second glass 220. 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. In this embodiment, the first surface 211 and the second surface 212 are parallel, that is, the first glass 210 is glass of uniform thickness.

[0031] The second glass 220 is the glass of the vehicle window 200 facing the interior of the vehicle 1000, and is opposite to and spaced apart from the first glass 210. Specifically, the second glass 220 is located on the side of the second surface 212 that faces away from 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 positioned opposite to the third surface 221 and faces the interior of the vehicle 1000. In this embodiment, the fourth surface 222 is parallel to the third surface 221, that is, the second glass 220 is glass of uniform thickness.

[0032] The connecting layer 225 includes a first connecting layer 230 and a second connecting layer 240. Both the first connecting layer 230 and the second connecting layer 240 are located between the first glass 210 and the second glass 220. The first connecting layer 230 is bonded to the first glass 210. Specifically, the first connecting layer 230 is located between the second surface 212 and the third surface 221, and is bonded to the second surface 212. The second connecting layer 240 is located between the first connecting layer 230 and the second glass 220, and is bonded to the second glass 220. Specifically, the second connecting layer 240 is located between the first connecting layer 230 and the third surface 221, and is bonded to the third surface 221. A portion of the second connecting layer 240 is also bonded to the first connecting layer 230.

[0033] The window glass 200 includes a mounting surface a located in the sunshade area 200e. The mounting surface a is spherical. The mounting surface a has a lateral curvature along the width direction of the window glass 200 and a longitudinal curvature along the length direction of the window glass 200. There are one or more mounting surfaces a. Wherein, a first surface 211 includes the mounting surface a, and / or, a second surface 212 includes the mounting surface a, and / or, a third surface 221 includes the mounting surface a, and / or, a fourth surface 222 includes the mounting surface a.

[0034] The window glass assembly B also includes a dimming film 300. The dimming film 300 is disposed on the window glass 200, on the mounting surface a, and located in the sunshade area 200e. In this embodiment, the dimming film 300 is located between the first glass 210 and the second glass 220, and between the first connecting layer 230 and the second connecting layer 240. The dimming film 300 is bonded and fixed between the first glass 210 and the second glass 220 through the first connecting layer 230 and the second connecting layer 240. The dimming film 300 can change the light intensity in the sunshade area 200e. When the light is too strong, the dimming film 300 is in a closed state, but maintains its sunshade function, which can prevent driver visual fatigue. When the light is insufficient, the dimming function of the dimming film 300 is activated, which can improve the driver's field of vision brightness and enhance the visibility of the window glass assembly B. It should be noted that the dimming film 300 is located outside areas A 200c and B 200d to ensure that it does not obstruct areas A 200c and B 200d and thus affect the clarity of the external environment observed by the driver and passengers through the first and second areas, thereby ensuring the driving safety of vehicle 1000. In some other embodiments, the dimming film 300 may also be located between the first glass 210 and the connecting layer 225, or it may be located between the second glass 220 and the connecting layer 225; this application does not impose any limitations on this.

[0035] In existing automotive window glass assemblies, due to unreasonable mounting surface design and the inherent hardness of the dimming film 300 material, the mounting surface and the dimming film 300 cannot adhere well, resulting in wrinkles in the dimming film 300. This increases the maintenance cost of the automotive window glass assembly and affects its aesthetics. This application addresses this issue by designing relevant parameters of mounting surface a, such as the spherical value d0 and the ratio between the first arch height value d1 and the second arch height value d2, to achieve a suitable curvature for mounting surface a. This allows the dimming film 300 to be better installed on mounting surface a, thereby reducing wrinkles in the dimming film 300. The mounting surface a for installing the dimming film 300 will be described in detail below.

[0036] Please see Figure 4 , Figure 4 yes Figure 2 A plan view of mounting surface a in the window glass assembly B shown.

[0037] Mounting surface a protrudes outward toward the vehicle 1000. In this embodiment, the window glass 200 is a panoramic windshield, and the ratio between the length and width of mounting surface a is greater than or equal to 1.5 and less than or equal to 3. It should be noted that the length of mounting surface a refers to its dimension in the longitudinal direction (X-axis direction in the figure) of the window glass 200, and the width of mounting surface a refers to its dimension in the transverse direction (Y-axis direction in the figure) of the window glass 200.

[0038] Please refer to the following: Figure 5 , Figure 5 yes Figure 4 The diagram shows a cross-sectional view of the mounting surface a along point AA.

[0039] The spherical value d0 of mounting surface a in the width direction of the window glass 200 is greater than 0 mm / m and less than or equal to 27 mm / m. This limits the curvature of mounting surface a in the width direction of the window glass 200, facilitating the fit between the dimming film 300 and mounting surface a, reducing wrinkles in the dimming film 300, lowering maintenance costs, improving the aesthetics of the window glass assembly B, and enhancing the driving experience for passengers. It should be noted that the spherical value d0 of mounting surface a is the arc depth of the Y-axis center arc. That is, the spherical value d0 of mounting surface a is the maximum arc height of the intersection line of mounting surface a and the central vertical section AA, where the central vertical section AA is parallel to the width and thickness directions of the window glass 200 and passes through the centerline 11 of the length direction of mounting surface a.

[0040] Please refer to the following: Figure 4 and 6 , Figure 6 yes Figure 4 The diagram shows a cross-sectional view of the mounting surface a along line B1-B1.

[0041] Mounting surface a has a first end b1 and a second end b2. Along the width direction of the window glass 200, the first end b1 and the second end b2 are positioned opposite each other. The arch height of the first end b1 is a first arch height value d1. It should be noted that the first arch height value d1 is the arc height of the first intersection line 22 between the first end b1 and the first transverse section B1-B1, representing the curvature of the first end b1 along the length direction of the window glass 200. The first transverse section B1-B1 is parallel to both the length and thickness directions of the window glass 200.

[0042] Please refer to the following: Figure 4 and Figure 7 , Figure 7 yes Figure 4 The diagram shows a cross-sectional view of the mounting surface a along line B2-B2.

[0043] In this embodiment, the second end b2 is located on the side of the first end b1 near the bottom of the window glass 200. The arch height of the second end b2 is a second arch height value d2. It should be noted that the second arch height value d2 is the arc height of the second intersection line 33 between the second end b2 and the second transverse section B2-B2, representing the curvature of the second end b2 in the length direction of the window glass 200. The second transverse section B2-B2 is parallel to both the length and thickness directions of the window glass 200.

[0044] In this embodiment, the ratio between the first arch height value d1 and the second arch height value d2 is greater than or equal to 0.85 and less than or equal to 1.05. Along the width direction of the window glass 200, the curvature of the mounting surface a changes little, so that the dimming film 300 can fit with the mounting surface a, reducing wrinkles in the dimming film 300, lowering maintenance costs, improving the aesthetics of the window glass assembly B, and improving the driving experience of the occupants.

[0045] This application conducted an experiment on a window glass assembly B of a window glass 200 having a ratio between a first arch height value d1 and a second arch height value d2, and a spherical value d0, to verify whether the dimming film 300 in the window glass assembly B would produce wrinkles. The experimental results are shown in Table 1 below.

[0046] Table 1. Experimental Results of Window Glass Assembly B (Panoramic Glass)

[0047] It should be noted that the evaluation standard for whether the dimming film 300 has wrinkles is as follows: under natural conditions or standard light source, observe the flatness and appearance of the dimming film in the car window glass assembly B from different angles to see if it has uniformity. If the flatness and appearance of the dimming film 300 are uniform, it means that the dimming film 300 has no wrinkles. If the flatness and appearance of the dimming film 300 are not uniform, it means that the dimming film 300 has wrinkles.

[0048] The experimental data shows that when the spherical value d0 is less than 27 mm / m and the ratio between the first arch height value d1 and the second arch height value d2 is greater than 0.85 and less than 1.05, no wrinkles are generated in the dimming film 300 in the window glass assembly B; when the spherical value d0 is greater than or equal to 27.2 mm / m and the ratio between the first arch height value d1 and the second arch height value d2 is greater than 1.05, wrinkles are generated in the dimming film 300 in the window glass assembly B.

[0049] In some other embodiments, the window glass 200 can be a regular windshield. The ratio between the length and width of the mounting surface a is greater than 3 and less than or equal to 5. The spherical value d0 of the mounting surface a in the width direction of the window glass 200 is greater than 0 mm / m and less than or equal to 20 mm / m, limiting the curvature of the mounting surface a in the width direction of the window glass 200. This facilitates the fit between the dimming film 300 and the mounting surface a, reducing wrinkles in the dimming film 300 and improving the aesthetics of the window glass assembly B. The ratio between the first arch height value d1 and the second arch height value d2 is greater than or equal to 0.9 and less than or equal to 1.0. Along the width direction of the window glass 200, the curvature of the mounting surface a changes little, facilitating the fit between the dimming film 300 and the mounting surface a, reducing wrinkles in the dimming film 300, lowering maintenance costs, improving the aesthetics of the window glass assembly B, and enhancing the driving experience for passengers.

[0050] This application conducted experiments on a car window glass assembly B with different ratios between the first arch height value d1 and the second arch height value d2, and the spherical value d0, to verify whether the dimming film 300 would produce wrinkles. The experimental results are shown in Table 2 below.

[0051] Table 2. Experimental Results of Vehicle Window Glass Assembly B (Ordinary Glass)

[0052] The experimental data shows that when the spherical value d0 is greater than 20, the ratio between the first arch height value d1 and the second arch height value d2 is less than 0.9, or the ratio between the first arch height value d1 and the second arch height value d2 is greater than 1, the dimming film 300 of the window glass assembly B produces wrinkles; when the spherical value d0 is less than 20, and the ratio between the first arch height value d1 and the second arch height value d2 is greater than or equal to 0.9 and less than 1.0, the dimming film 300 of the window glass assembly B does not produce wrinkles.

[0053] This application ensures that the curvature of the mounting surface a is appropriate by setting the spherical value d0 of the mounting surface a and the ratio between the first arch height value d1 and the second arch height value d2, so that the dimming film 300 can fit with the window glass 200. This avoids wrinkles caused by excessive curvature of the mounting surface a, reduces maintenance costs, improves the aesthetics of the window glass assembly B, and enhances the driving experience for passengers.

The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of this application and are not intended to limit the patent scope of this application. At the same time, for those skilled in the art, equivalent structural transformations made based on the inventive concept of this application using the specification and drawings of this application, or direct / indirect applications in other related technical fields, are all included within the patent protection scope of this application.
