Description

Technical Field

[0001] The present application relates to the field of glass technology, and in particular to a glass assembly and a vehicle. Background Art

[0002] Car windows are an essential component of a vehicle. To ensure driving safety, they must possess safety performance parameters such as high strength and rigidity. Car windows, including but not limited to front, side, and rear windshields, are typically designed with silver and film coatings. The silver coating primarily reflects solar radiation, lowering the interior temperature, improving comfort, and reducing air conditioning loads. The silver coating also enhances comfort and protects the interior by reflecting solar radiation and blocking UV rays. Some windows also feature electric heating. The film coating reduces heat in the overhead area of the vehicle, preventing sunburn.

[0003] In order to expand the driver's field of view, the longitudinal length of the front windshield is usually extended to the rear of the front seats, such as the B-pillar position, to form a new "panoramic" front windshield, thereby improving the comfort and field of view of the driver and passengers. As the size of the front windshield increases, the energy of sunlight transmitted into the cab increases accordingly. In order to reduce sunburn, it is necessary to add a sun protection coating layer to the top area of the front windshield. However, especially when the coating layer is only provided in the top area, defects such as refraction, rainbow stripes, bright lines, etc. will appear at the junction of the coating area and the field of view, resulting in poor appearance quality of the product.

[0034] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0035] It should be noted that, for the convenience of description, the “top” and “bottom” in this embodiment are both based on the state of the glass assembly when it is normally installed on a vehicle for use.

[0036] As described in the background art, in the prior art, especially when the coating layer is only provided in the top area of the head, defects such as refraction, rainbow stripes, and bright lines may appear at the junction of the coating area and the viewing area, resulting in poor product appearance quality. The inventors have found that the reason for this problem is that, on the one hand, the thermal expansion coefficient of the viewing area is, for example, 8.5~9.5×10 -6 / ℃, the thermal expansion coefficient of the coating area is, for example, 10~12×10 -6 / ℃, that is, the thermal expansion coefficients of the coating area and the viewing area are different, and during the molding process, micro-deformation occurs at the junction (which is difficult to detect with the naked eye); on the other hand, the refractive index of light in the coating area is, for example, 1.5~2.0, and the refractive index of light in the viewing area is, for example, 1.5. In this way, the refractive index of light in the coating area is different from that of light in the viewing area, which will easily cause distortion or blurring defects of light at the junction.

[0037] Based on the above reasons, the present application provides a technical solution for a glass assembly and a vehicle that can improve the appearance quality of the product and effectively prevent defects such as refraction, rainbow stripes, and bright lines.

[0038] See Figures 1 to 3 , Figure 1 A structural diagram showing a glass assembly 10 according to an embodiment of the present application applied to a vehicle is shown. Figure 2 A structural diagram of a glass assembly 10 according to an embodiment of the present application is shown. Figure 3 Shown Figure 2 Cross-sectional structural diagram of the first embodiment at AA. A glass assembly 10 provided in one embodiment of the present application includes a glass body 11, a coating layer 12, and a first shielding layer 13. The glass body 11 is provided with a coating area 1101 and a viewing area 1102. A boundary line 1103 is formed at the connection between the coating area 1101 and the viewing area 1102. The coating layer 12 is provided on the glass body 11, and the coating layer 12 covers the coating area 1101, and the coating layer 12 does not cover the viewing area 1102. The first shielding layer 13 is provided on the glass body 11, and the first shielding layer 13 covers the boundary line 1103. The first shielding layer 13 includes two opposite contour edges 1301. The two contour edges 1301 are respectively provided in the coating area 1101 and the viewing area 1102.

[0039] For example, the coating layer 12 includes a metal layer and a dielectric layer connected to the metal layer. The coating layer 12 including the metal layer enables the glass assembly 10 to have an electrical heating function when powered. When the glass assembly 10 is manufactured into laminated glass, the temperature of the laminated glass can be increased, thereby preventing fogging, achieving defrosting, defrosting, and deicing functions, thereby improving driving safety.

[0040] For example, the coating layer 12 satisfies one or more of the following conditions:

[0041] (1) The material of each metal layer is independently selected from any one of Ag, Au, Cu and Al or a metal alloy;

[0042] (2) The physical thickness of each metal layer is independently 5 nm to 20 nm;

[0043] (3) The material of each dielectric layer is independently selected from the oxide of at least one element among Zn, Mg, Sn, Ti, Nb, Zr, Ni, In, Al, Ce, W, Mo, Sb, and Bi;

[0044] (4) The physical thickness of each dielectric layer is independently 5 nm to 30 nm.

[0045] The metal layer has the characteristics of reflecting infrared rays and having good electrical conductivity. The material of each metal layer is independently selected from any one of silver (Ag), gold (Au), copper (Cu), and aluminum (Al) metal or metal alloy; specific examples include Ag metal, AgCu alloy, AgIn alloy, AgCuAl alloy, etc. The coating layer 12 including the metal layer gives the glass assembly 10 excellent thermal insulation function, thereby significantly reducing air conditioning energy consumption and improving the thermal comfort of the driver and passengers. In addition, the coating layer 12 can also give the glass assembly 10 an electric heating function after power is applied. After the glass assembly 10 is manufactured into laminated glass, the temperature of the laminated glass can be increased, thereby achieving functions such as preventing fogging or defogging, defrosting, and deicing, thereby improving driving safety. For example, the power supply voltage of the laminated glass can be 12V to 380V.

[0046] The physical thickness of each metal layer is independently 5 nm to 20 nm. For example, the physical thickness of each metal layer is independently 5 nm, 8 nm, 10 nm, 12 nm, 14 nm, 16 nm, 18 nm, 20 nm, or a range consisting of any two of these values.

[0047] For example, a barrier layer can also be deposited between the metal layer and the dielectric layer. The barrier layer is in direct contact with the metal layer. The physical thickness of the barrier layer is less than or equal to 5 nm. The material of the barrier layer is selected from at least one metal or metal alloy of Ti, Ni, Cr, Nb, and W. The barrier layer is mainly used to prevent the metal layer from contacting the oxidizing reaction gas during magnetron sputtering and to improve the optical properties of the coating layer 12.

[0048] Each dielectric layer enables the coating layer 12 to withstand subsequent high-temperature bending processes of at least 500°C, protecting the metal layer from oxidation and corrosion while also facilitating denser metal layer deposition. The resulting coated glass's optical and mechanical properties meet vehicle glazing standards. The material of each dielectric layer is independently selected from oxides of at least one element selected from the group consisting of Zn, Mg, Sn, Ti, Nb, Zr, Ni, In, Al, Ce, W, Mo, Sb, and Bi. Specific examples include AZO, NbOx, TiOx, ZnAlOx, ZnOx, SnOx, and ZnSnOx.

[0049] The physical thickness of each dielectric layer is independently 5 nm to 30 nm. For example, the physical thickness of each dielectric layer is independently 5 nm, 8 nm, 10 nm, 12 nm, 14 nm, 16 nm, 18 nm, 20 nm, 24 nm, 27 nm, 30 nm, or a range consisting of any two of these values.

[0050] For example, the coating layer 12 includes but is not limited to a nanofilm.

[0051] For example, the coating layer 12 can be at least one selected from a single silver nanofilm, a double silver nanofilm, a triple silver nanofilm, a quadruple silver nanofilm, an ITO nanofilm, an FTO nanofilm, and an infrared blocking microfilm. The single silver nanofilm, the double silver nanofilm, the triple silver nanofilm, the quadruple silver nanofilm, the ITO nanofilm, and the FTO nanofilm can be formed by a physical vapor deposition process (PVD) or a chemical vapor deposition process (CVD), and their physical thickness is, for example, selected from 100 nm to 500 nm. The infrared blocking microfilm can be formed by sol-gel coating, and the thickness of the infrared blocking microfilm is 5 μm to 30 μm. The infrared blocking microfilm is a transparent microfilm with infrared blocking nanoparticles, and the material of the infrared blocking nanoparticles can be selected from at least one of ITO (indium tin oxide), FTO (fluorine-doped tin oxide), CWO (cesium-doped tungsten oxide), lanthanum hexaboride (LaB6), and vanadium pentoxide (V2O5). The average particle size of the infrared blocking nanoparticles is 20 nm to 100 nm.

[0052] For example, the glass assembly 10 may be used in various environments, including, but not limited to, being installed on a vehicle, specifically a vehicle window; being installed on a building; and being installed on a container. In this embodiment, the glass assembly 10 is specifically installed on a vehicle, but the present invention is not limited thereto.

[0053] In the above-mentioned glass assembly 10, on the one hand, since the coating layer 12 covers the coating area 1101, the coating layer 12 can reduce the light intensity and lower the temperature of the coating area 1101, thereby effectively preventing burns to the driver and passengers; on the other hand, since the coating layer 12 does not cover the viewing area 1102, the viewing area 1102 is clearer, which is convenient for the driver and passengers to observe; in addition, the glass assembly 10 also includes a first shielding layer 13, the first shielding layer 13 covers the boundary line 1103, and the two contour edges 1301 of the first shielding layer 13 are respectively arranged in the coating area 1101 and the viewing area 1102. In this way, the shielding property of the first shielding layer 13 can indirectly eliminate or reduce the product appearance defects at the boundary line 1103, prevent the occurrence of defects such as refraction, rainbow stripes, and bright lines, thereby improving the value of the product, and providing the driver and passengers with a comfortable field of view, so that the driving safety factor can be improved.

[0054] For example, the visible light transmittance of the first shielding layer 13 is less than or equal to 5%, more preferably less than or equal to 3%, further preferably less than or equal to 1%, or even less than or equal to 0.5%, or substantially 0%, i.e., the first shielding layer 13 is a dark-colored printed layer or a dark-colored polymer film.

[0055] The dark printing layer may be black or brown ceramic ink or ultraviolet ink, and may be printed on the glass body 11 by screen printing, inkjet printing or other processes.

[0056] In addition, the dark polymer film can be a polymer film with body coloring, for example, a coloring component is added during the manufacturing process of the polymer film to obtain black or brown PVB, PET, PVC, etc.; or a polymer film with surface printing pigments, for example, black or brown pigments are printed on the surface of the polymer film, etc.

[0057] See also Figure 2 、 Figures 9 to 12 In one embodiment, the first shielding layer 13 includes a main body portion 131 and a transition portion 132 connected to the main body portion 131 . The main body portion 131 extends along the extending direction of the boundary line 1103 and covers the boundary line 1103 .

[0058] For example, the shape of the main body 131 can be flexibly adjusted and configured according to actual needs, such as a rectangle, a curved ribbon, or other irregular shapes. Furthermore, the entire area of the main body 131 is covered with a masking material. Thus, the main body 131 plays a primary role in shielding the appearance defects at the boundary line 1103.

[0059] In addition, the transition portion 132 is one and is located on any side of the main body portion 131 along its width direction. Figure 10 and Figure 11Alternatively, there are two transition portions 132, which are located on opposite sides of the main body 131 along its width direction, as shown in FIG. Figure 12 shown.

[0060] Of course, the transition portion 132 may also be omitted. Figure 9 shown.

[0061] The shielding material distribution density of the main body 131 is greater than that of the transition portion 132; the shielding material distribution density of the transition portion 132 increases as it approaches the boundary line 1103. This arrangement allows the main body 131 to primarily shield appearance defects at the boundary line 1103, while the transition portion 132 acts as a transition, ensuring more uniform heating and light distribution. This effectively prevents defects such as refraction, rainbow streaks, and bright lines, improving product appearance quality.

[0062] For example, the shape of the transition portion 132 can be flexibly adjusted and configured according to actual needs, such as a rectangle, a curved ribbon, or other irregular shape. Furthermore, the transition portion 132 can include a plurality of shielding blocks 1321 arranged in an array. The shielding blocks 1321 can be shaped, for example, circular, elliptical, polygonal, or other regular or irregular shapes. Furthermore, the density of the shielding blocks 1321 increases as they approach the boundary line 1103, thereby increasing the density of the shielding material within the transition portion 132.

[0063] The density of the shielding blocks 1321 can be increased by the following methods:

[0064] For example, this can be achieved by adjusting the number of shielding blocks 1321 arranged at different positions. Specifically, the number of shielding blocks 1321 near the boundary line 1103 is greater than the number of shielding blocks 1321 farther from the boundary line 1103. In other words, the number of shielding blocks 1321 arranged per unit area increases in the direction closer to the boundary line 1103.

[0065] For another example, when the number of shielding blocks 1321 at different positions remains substantially the same, this can be achieved by adjusting the areas of the shielding blocks 1321 at different positions. Specifically, the areas of the shielding blocks 1321 closer to the boundary line 1103 are made larger than the areas of the shielding blocks 1321 farther from the boundary line 1103. In other words, the areas of the shielding blocks 1321 increase in the direction closer to the boundary line 1103.

[0066] See also Figure 3For example, the distance between the boundary line 1103 and the contour edge 1301 is D. Optionally, 3 mm ≤ D ≤ 50 mm. Specifically, D is, for example, 3 mm, 5 mm, 10 mm, 12 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, or 50 mm.

[0067] It should be noted that the distance D between the two contour edges 1301 and the boundary line 1103 can be the same or different. The specific setting can be flexibly adjusted and set according to actual needs. It is not limited here, as long as the defects such as refraction, rainbow stripes, bright lines, etc. at the boundary line 1103 can be blocked.

[0068] During production, the positional tolerance of the first shielding layer 13 is approximately ±1.5 mm, and the positional tolerance of the coating layer 12 is approximately ±1.5 mm. Therefore, the lower limit of the spacing D is set to 3 mm. Furthermore, the upper limit of the spacing D depends primarily on factors such as the expansion coefficient and reflectivity of the coating area 1101 and the viewing area 1102 during production, which can lead to the width of an optically defective area at the boundary line 1103. The width of the defective area is typically, for example, 20 mm to 50 mm. Therefore, the upper limit of the spacing D is set to 50 mm. There is no need to set the spacing D greater than 50 mm, which would reduce the area of the viewing area 1102.

[0069] It should be noted that the length direction in this embodiment refers to, for example, the extending direction of the boundary line 1103, and the width direction in this embodiment refers to, for example, the direction perpendicular to the boundary line 1103 and parallel to the first shielding layer 13. Accordingly, the width of the first shielding layer 13 refers to the distance between the two contour edges 1301.

[0070] See also Figure 1 and Figure 2 In one embodiment, the ratio of the area of the coating area 1101 to the area of the glass body 11 is 20% to 40%, and the ratio of the area of the viewing area 1102 to the area of the glass body 11 is 60% to 80%.

[0071] For example, the coating area 1101 is located above the head of the driver and passenger to provide sun protection. Optionally, the ratio of the area of the coating area 1101 to the area of the glass body 11 includes, but is not limited to, 20% to 40%, specifically 20%, 22%, 25%, 30%, 35% or 40%, etc., and can be flexibly adjusted and set according to actual needs. In this way, the area of the coating area 1101 is appropriately set. On the one hand, the coating area 1101 is relatively large, which can ensure that the driver and passenger's head is shielded, effectively cooling and sun-proofing; on the other hand, the coating area 1101 is relatively small, which increases the area of the field of view 1102, thereby providing the driver and passenger with a larger field of view 1102.

[0072] For example, viewing area 1102 is located in front of the driver and passengers, ensuring a clear field of view. Optionally, the area of viewing area 1102 is larger than the area of coating area 1101. The ratio of the area of viewing area 1102 to the area of glass body 11 is 60% to 80%, and specifically, 60%, 62%, 65%, 70%, 75%, or 80%, etc., and can be flexibly adjusted and set according to actual needs.

[0073] In one embodiment, field of view 1102 includes an image acquisition area 1104 corresponding to the camera position, and the shortest distance S between boundary line 1103 and image acquisition area 1104 is ≥ 10 mm. Thus, a larger shortest distance S between boundary line 1103 and image acquisition area 1104 can prevent defects such as refraction, rainbow fringes, and bright lines from appearing in image acquisition area 1104 when distance S is too small. This improves the quality of images captured by the camera and prevents the captured image from being affected by the appearance of the product at boundary line 1103.

[0074] Based on the above embodiment, S≤100 mm. Specifically, S is, for example, 10 mm, 12 mm, 13 mm, 14 mm, 15 mm, 18 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 80 mm, or 100 mm.

[0075] See also Figure 2 In one embodiment, the glass assembly 10 further includes a second shielding layer 14. The second shielding layer 14 is disposed on the glass body 11 and extends from the top edge of the glass body 11 to the viewing area 1102. The image acquisition area 1104 is at least partially surrounded by the second shielding layer 14.

[0076] In some embodiments, the second shielding layer 14 may be completely disposed around the image acquisition area 1104. Alternatively, in some embodiments, the second shielding layer 14 may be disposed only around the top of the image acquisition area 1104. In this way, the second shielding layer 14 can be used to shield other accessory structures besides the camera, thereby improving the appearance quality of the product.

[0077] For example, the outer contour shape of the second shielding layer 14 is set to correspond to the outer contour shape of the projection of the camera host on the glass body 11 in a direction perpendicular to the glass body 11 to ensure that the camera host can be blocked; at the same time, the area of the second shielding layer 14 is made as small as possible to increase the area of the field of view 1102.

[0078] Optionally, the outer contour shape of the second shielding layer 14 includes but is not limited to various regular and irregular shapes such as trapezoid, triangle, rectangle, and ellipse, which can be flexibly adjusted and set according to actual needs and is not limited here.

[0079] The material of the second shielding layer 14 may also be a dark-colored printed layer or a dark-colored polymer film consistent with the first shielding layer 13 , which will not be described in detail here.

[0080] It should be noted that the glass body 11 can be configured as either single-piece glass or laminated glass, and can be flexibly adjusted and configured according to actual needs. Since laminated glass has greater rigidity, this embodiment will be specifically described using the glass body 11 configured as laminated glass as an example, but the invention is not limited thereto.

[0081] See also Figure 3 In one embodiment, the glass body 11 includes a first glass plate 111, a second glass plate 112, and an adhesive layer 113. The first glass plate 111 has a first surface 1111 and a second surface 1112, which are opposite to each other. The first surface 1111 faces the external environment. The second glass plate 112 has a third surface 1121 and a fourth surface 1122, which are opposite to each other. The fourth surface 1122 faces the internal environment. The adhesive layer 113 is disposed between the first glass plate 111 and the second glass plate 112. The coating layer 12 is disposed on at least one of the second surface 1112, the third surface 1121, and the fourth surface 1122. The first shielding layer 13 is disposed on at least one of the second surface 1112, the third surface 1121, and the fourth surface 1122.

[0082] It should be noted that, taking the glass assembly 10 being installed in a vehicle as an example, the external environment is, for example, outside the vehicle, and the internal environment is, for example, inside the vehicle.

[0083] See also Figure 3 For example, the first shielding layer 13 is disposed on the second surface 1112. Thus, based on the arc shape of the glass body 11, disposing the first shielding layer 13 on the second surface 1112, especially when the first shielding layer 13 is a printed layer printed on the second surface 1112, can meet the processing requirements and prevent the roller from contacting the printed layer and causing damage to the first shielding layer 13.

[0084] See also Figure 3 For example, the coating layer 12 is disposed on the second surface 1112 or the third surface 1121. In this manner, the coating layer 12 is located in the area between the first glass plate 111 and the second glass plate 112 without being exposed and thus protected from damage.

[0085] See also Figure 3In one embodiment, both the first shielding layer 13 and the coating layer 12 are disposed on the second surface 1112. In a specific process, for example, a printed layer is first printed on the second surface 1112 to form the first shielding layer 13. Then, the coating layer 12 is formed by coating the coating area 1101 of the second surface 1112. This method, as demonstrated through testing, effectively prevents defects such as refraction, rainbow streaks, and bright lines at the boundary line 1103, thereby enhancing the product's value.

[0086] The glass assembly 10 in the present application can eliminate / reduce the poor appearance of the product at the boundary line 1103, so that the functions of the glass assembly 10 are improved, such as dimming, heat insulation, sound insulation, etc.; and the appearance of the product is no worse than the original configuration, thereby providing a good experience to the driver and passengers, such as comfort and security.

[0087] See also Figure 4 、 Figure 6 and Figure 8 In one embodiment, the glass assembly 10 further includes a third shielding layer 15. The third shielding layer 15 is disposed on the fourth surface 1122. The third shielding layer 15 and the first shielding layer 13 are aligned along the thickness direction of the glass body 11, and the shape of the third shielding layer 15 corresponds to that of the first shielding layer 13. Thus, the third shielding layer 15 also covers the boundary line 1103. The third shielding layer 15 can shield product appearance defects at the boundary line 1103, better preventing defects such as refraction, rainbow streaks, and bright lines.

[0088] It should be noted that the third shielding layer 15 can also be a dark printing layer or dark polymer film that is consistent with the first shielding layer 13. The specific setting can be flexibly adjusted and set according to actual needs and will not be repeated here.

[0089] Of course, as some optional solutions, the third shielding layer 15 can also be omitted, for example Figure 3 、 Figure 6 or Figure 7 shown.

[0090] See also Figures 3 to 8 For example, the glass assembly 10 further includes a fourth shielding layer 16. The fourth shielding layer 16 is disposed on the outer peripheral edge of the glass body 11. The fourth shielding layer 16 can be disposed on at least one of the second surface 1112, the third surface 1121, and the fourth surface 1122 according to actual needs. For example, see Figure 3 and Figure 4 , the fourth shielding layer 16 is disposed on the second surface 1112; for example, see Figure 5 and Figure 6 , the fourth shielding layer 16 is disposed on the fourth surface 1122; for example, see Figure 7 and Figure 8 The second surface 1112 and the fourth surface 1122 are both provided with a fourth shielding layer 16. The fourth shielding layer 16 blocks light and forms a black edge at the outer edge of the glass body 11, which plays a shielding role and is therefore also called a black edge, which can improve the appearance quality of the product.

[0091] It should be noted that the fourth shielding layer 16 may also be a dark-colored printed layer or dark-colored polymer film consistent with the first shielding layer 13 . The specific configuration can be flexibly adjusted and configured according to actual needs, and will not be elaborated herein.

[0092] For example, the first glass plate 111 includes, but is not limited to, tempered glass, more specifically, heat-strengthened glass. The thickness of the first glass plate 111 ranges from, but is not limited to, 1.6 mm to 2.3 mm, specifically, 1.6 mm, 1.8 mm, 1.9 mm, 2 mm, 2.2 mm, or 2.3 mm. Furthermore, the color of the first glass plate 111 can be, for example, green glass or white glass, and can be flexibly adjusted and configured based on actual needs.

[0093] The second glass plate 112 is configured similarly to the first glass plate 111. For example, the second glass plate 112 includes, but is not limited to, tempered glass, more specifically, heat-strengthened glass. The thickness of the second glass plate 112 includes, but is not limited to, 1.6 mm to 2.3 mm, specifically, 1.6 mm, 1.8 mm, 1.9 mm, 2 mm, 2.2 mm, or 2.3 mm. Furthermore, the color of the second glass plate 112 can be, for example, green glass or white glass, and can be flexibly adjusted and configured according to actual needs.

[0094] In this embodiment, the adhesive layer 113 primarily serves to bond the first glass plate 111 to the second glass plate 112. Optionally, the adhesive layer 113 is a film having at least one of the following functions: sound insulation, heat insulation, and dimming. The adhesive layer 113 can be a single layer or a multi-layer composite adhesive layer, with flexibility depending on actual needs. The thickness of the adhesive layer 113 includes, but is not limited to, 0.05 mm to 0.76 mm, with specific thicknesses including, for example, 0.05 mm, 0.38 mm, and 0.76 mm.

[0095] Optionally, the adhesive layer 113 includes but is not limited to being made of PVB material, EVA material, TPU material or SGP material.

[0096] Optionally, the adhesive layer 113 can be entirely transparent, meaning that the portions of the adhesive layer 113 corresponding to the coating area 1101 and the viewing area 1102 are all made of a transparent material. Alternatively, the adhesive layer 113 can be partially transparent, with the transparent portion having a visible light transmittance greater than 90%, or even greater than 95%, and the opaque portion having a visible light transmittance less than 50%, specifically less than 35%, 20%, 10%, or 3%. The opaque portion can be colored, including but not limited to green, blue, gray, or transitional colors, and can be flexibly adjusted and configured based on actual needs.

[0097] As an example, the portion of the adhesive layer 113 corresponding to the viewing area 1102 is made of a transparent material to ensure a clear view of the viewing area 1102; the portion of the adhesive layer 113 corresponding to the coating area 1101 is made of a non-transparent material to block light and thereby achieve a scalding protection effect. The visible light transmittance of the transparent material is, for example, greater than 90%, or even greater than 95%; the visible light transmittance of the non-transparent material is, for example, less than 50%, specifically less than 50%, 35%, 20%, 10%, or 3%.

[0098] See also Figures 1 to 3 In one embodiment, this embodiment further provides a vehicle, including but not limited to a car, bus, sedan, public bus, coach, truck, jeep, train, high-speed train, etc. The vehicle includes the glass assembly 10 of any of the above embodiments. The glass assembly 10 includes but is not limited to the front windshield, side windshields, rear windshield, and sunroof glass of the vehicle.

[0099] In the above-mentioned vehicle, on the one hand, since the coating layer 12 covers the coating area 1101, the coating layer 12 can reduce the light intensity and lower the temperature of the coating area 1101 in the coating area 1101, thereby effectively preventing scalding of the driver and passengers; on the other hand, since the coating layer 12 does not cover the viewing area 1102, the viewing area 1102 is clearer, which is convenient for the driver and passengers to observe; in addition, the glass assembly 10 also includes a first shielding layer 13, the first shielding layer 13 covers the boundary line 1103, and the two contour edges 1301 of the first shielding layer 13 are respectively arranged in the coating area 1101 and the viewing area 1102. In this way, the shielding property of the first shielding layer 13 can indirectly eliminate or reduce the product appearance defects at the boundary line 1103, prevent the occurrence of defects such as refraction, rainbow stripes, and bright lines, thereby improving the value of the product, and providing the driver and passengers with a comfortable field of vision, so that the driving safety factor can be improved.
