Abstract
Description
Technical Field
[0001] This application relates to the field of glass technology, and in particular to a glass component and a vehicle. Background Technology
[0002] Car windows are a crucial component of a vehicle. To ensure driving safety, car window glass must possess high strength, rigidity, and other safety performance parameters. Car window glass, including but not limited to the windshield, side windows, and rear window, is typically designed with a silver plating layer and a protective coating. The silver plating layer primarily reflects solar radiation, reducing interior temperature, improving comfort, and reducing air conditioning load. It also reflects solar radiation and blocks ultraviolet rays, enhancing comfort and protecting the interior. Some models even feature electric heating. The protective coating layer reduces heat in the overhead area of the car, preventing sunburn.
[0003] To expand the driver's field of vision, the longitudinal length of the windshield is often extended behind the front seats, such as at the B-pillar, creating a new "panoramic" windshield, thereby improving passenger comfort and visibility. As the size of the windshield increases, more sunlight penetrates into the cabin. To reduce sunburn, a sun-protective coating is added to the overhead area of the windshield. However, especially when the coating is only applied to the overhead area, defects such as refraction, rainbow stripes, and bright lines may appear at the boundary between the coated area and the field of vision, resulting in poor product appearance quality. Summary of the Invention
[0004] Therefore, it is necessary to overcome the shortcomings of the existing technology and provide a glass component and vehicle that can improve the appearance quality of the product and effectively prevent defects such as refraction, rainbow stripes, and bright lines.

[0007] A coating layer, wherein the coating layer is disposed on the glass body, the coating layer covers the coating area, and the coating layer does not cover the viewing area; and
[0008] A first shielding layer is disposed on the glass body and covers the boundary line. The first shielding layer includes two opposing contour edges, which are respectively disposed in the coating area and the viewing area.
[0009] In one embodiment, the first shielding layer includes a main body and a transition portion connected to the main body. The main body extends along the extension direction of the boundary line and covers the boundary line. The transition portion is one and located on either side of the main body along its width direction, or the transition portion is two and located on opposite sides of the main body along its width direction. The shielding material distribution density of the main body is greater than that of the transition portion. The shielding material distribution density of the transition portion increases in the direction close to the boundary line.
[0010] In one embodiment, the transition portion includes a plurality of shielding blocks arranged in an array, the density of which increases along a direction close to the boundary line.
[0011] In one embodiment, the distance between the boundary line and the contour edge is D, where 3mm ≤ D ≤ 50mm.

[0013] In one embodiment, the field of view includes an image acquisition area corresponding to the camera position, and the shortest distance S between the boundary line and the image acquisition area is ≥10mm.
[0014] In one embodiment, the glass assembly further includes a second shielding layer disposed on the glass body, the second shielding layer extending from the top edge of the glass body to the field of view; the image acquisition area is at least partially surrounded by the second shielding layer.
[0015] In one embodiment, the glass body includes: a first glass plate, a second glass plate, and an adhesive layer; the first glass plate has a first surface and a second surface facing away from each other, the first surface facing the external environment; the second glass plate has a third surface and a fourth surface facing away from each other, the fourth surface facing the internal environment; the adhesive layer is disposed between the first glass plate and the second glass plate; the coating layer is disposed on at least one of the second surface, the third surface, and the fourth surface; and the first shielding layer is disposed on at least one of the second surface, the third surface, and the fourth surface.

[0017] In one embodiment, the glass assembly further includes a third shielding layer disposed on the fourth surface, the third shielding layer being aligned with the first shielding layer along the thickness direction of the glass body, and the shape of the third shielding layer corresponding to that of the first shielding layer.
[0018] In one embodiment, the glass assembly further includes a fourth shielding layer disposed on the outer peripheral edge of the glass body, and the fourth shielding layer is disposed on at least one of the second surface, the third surface, and the fourth surface.
[0019] A means of transportation, the means of transportation including the glass assembly.
[0020] The aforementioned glass components and vehicles, on the one hand, because the coating layer covers the coating area, the coating layer can reduce the light intensity and lower the temperature of the coating area, thereby effectively preventing burns to drivers and passengers; on the other hand, because the coating layer does not cover the field of vision, the field of vision is clearer and easier for drivers and passengers to observe; in addition, the glass components also include a first shielding layer, which covers the boundary line.

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0035] It should be noted that, for ease of description, the terms "top" and "bottom" in this embodiment refer to the state when the glass assembly is normally installed and used in the vehicle.
[0036] As described in the background section, in existing technologies, particularly when the coating layer is only applied to the top of the head, defects such as refraction, rainbow stripes, and bright lines appear at the boundary between the coated area and the field of view, resulting in poor product appearance quality. The inventors have discovered that this problem arises because, on the one hand, the coefficient of thermal expansion of the field of view is, for example, 8.5~9.5×10⁻⁶. -6 / ℃, the coefficient of thermal expansion of the coated area is, for example, 10~12×10. -6 / ℃, meaning the coefficient of thermal expansion of the coating area and the viewing area are different. During the molding process, micro-deformation occurs at the interface (difficult to be identified by the naked eye). On the other hand, the refractive index of light in the coating area is, for example, 1.5~2.0, while the refractive index of light in the viewing area is, for example, 1.5. Thus, the refractive index of light in the coating area is different from that in the viewing area, which can easily lead to distortion or blurring of light at the interface.
[0037] For the reasons mentioned above, this application provides a glass component 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 of a glass assembly 10 according to an embodiment of this application applied to a vehicle is shown. Figure 2 A structural diagram of a glass assembly 10 according to an embodiment of this application is shown. Figure 3 It shows Figure 2 A cross-sectional view of the first embodiment at point AA. An embodiment of this application provides a glass assembly 10, including a glass body 11, a coating layer 12, and a first shielding layer 13. The glass body 11 has a coating area 1101 and a viewing area 1102. A boundary line 1103 is formed at the junction of the coating area 1101 and the viewing area 1102. The coating layer 12 is disposed on the glass body 11, covering the coating area 1101 but not covering the viewing area 1102. The first shielding layer 13 is disposed on the glass body 11, covering the boundary line 1103, and includes two opposing contour edges 1301. The two contour edges 1301 are respectively disposed 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. Thus, when the coating layer 12 includes a metal layer, the glass assembly 10 can have an electric heating function after being energized. 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 defrosting, de-icing, etc., and 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 metals or metal alloys;
[0042] (2) The physical thickness of each metal layer is independently 5nm to 20nm;
[0043] (3) The material of each dielectric layer is independently selected from oxides of at least one element selected from 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 5nm to 30nm.
[0045] The metal layers possess characteristics such as infrared reflection and good conductivity. The materials for each metal layer are independently selected from any one of the following metals or metal alloys: silver (Ag), gold (Au), copper (Cu), and aluminum (Al); specific examples include Ag metal, AgCu alloy, AgIn alloy, and AgCuAl alloy. The coating layer 12, including the metal layers, gives the glass assembly 10 excellent heat insulation properties, thereby significantly reducing air conditioning energy consumption and improving the thermal comfort of the driver and passengers. Furthermore, the coating layer 12 can also enable the glass assembly 10 to have an electric heating function when energized. After the glass assembly 10 is manufactured as laminated glass, the temperature of the laminated glass can be increased, thereby achieving functions such as preventing fogging or defrosting, frost removal, and de-icing, improving driving safety. For example, the voltage applied to the laminated glass can be from 12V to 380V.
[0046] The physical thickness of each metal layer is independently between 5 nm and 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 any combination of these values.
[0047] For example, a barrier layer may 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 selected from 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 or corrosion, promoting denser metal layer deposition, and ensuring that the optical and mechanical properties of the resulting coated glass meet the standards for automotive glass. The materials for each dielectric layer are independently selected from oxides of at least one element chosen from 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 between 5 nm and 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 any combination of these values.
[0050] For example, the coating layer 12 may include, but is not limited to, a nanofilm.
[0051] For example, the coating layer 12 can be at least one selected from single-silver nanofilms, double-silver nanofilms, triple-silver nanofilms, quadruple-silver nanofilms, ITO nanofilms, FTO nanofilms, and infrared-blocking microfilms. Single-silver nanofilms, double-silver nanofilms, triple-silver nanofilms, quadruple-silver nanofilms, ITO nanofilms, and FTO nanofilms can be formed by physical vapor deposition (PVD) or chemical vapor deposition (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 selected from 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 can be applied in various environments, such as on vehicles, specifically as vehicle windows; on buildings; or on shipping containers, etc. In this embodiment, the glass assembly 10 is specifically used as an example of being installed on a vehicle, but it is not limited thereto.
[0053] The aforementioned 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 temperature of the coating area 1101, thereby effectively preventing burns to drivers and passengers; on the other hand, since the coating layer 12 does not cover the field of vision area 1102, the field of vision area 1102 is clearer and easier for drivers and passengers to observe; in addition, the glass assembly 10 also includes a first shielding layer 13, which covers the boundary line 1103. The two contour edges 1301 of the first shielding layer 13 are respectively disposed in the coating area 1101 and the field of vision area 1102. In this way, the shielding property of the first shielding layer 13 can indirectly eliminate or reduce product appearance defects at the boundary line 1103, prevent defects such as refraction, rainbow stripes, and bright lines, thereby improving the value of the product and providing drivers and passengers with a comfortable field of vision, thus improving the driving safety factor.
[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%, even more preferably less than or equal to 1%, or even less than or equal to 0.5%, or essentially 0%, i.e., it is opaque to visible light. The first shielding layer 13 is a dark printed layer or a dark polymer film.
[0055] The dark printing layer can be black or brown ceramic ink or ultraviolet ink, which is printed on the glass body 11 through processes such as screen printing and inkjet printing.
[0056] In addition, dark polymer films can be bulk-colored polymer films, such as adding coloring components during the manufacturing process of polymer films to obtain black or brown PVB, PET, PVC, etc.; or polymer films with surface-printed pigments, such as printing black or brown pigments on the surface of polymer films.
[0057] Please see Figure 2 , Figures 9 to 12 In one embodiment, the first shielding layer 13 includes a main body 131 and a transition portion 132 connected to the main body 131. The main body 131 extends along the extension 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 set according to actual needs, such as being rectangular, curved, or other irregular shapes. Furthermore, the entire area of the main body 131 is covered with masking material. Thus, the main body 131 plays a major role in masking appearance defects at the boundary line 1103.
[0059] Furthermore, the transition portion 132 is a single portion located on any side of the main body portion 131 along its width direction, such as... Figure 10 and Figure 11As shown. Alternatively, the transition portion 132 may be two, located on opposite sides of the main body portion 131 along its width direction, as shown. Figure 12 As shown.
[0060] Of course, transition section 132 can also be omitted, for example... Figure 9 As shown.
[0061] The shielding material distribution density of the main body 131 is greater than that of the transition section 132; the shielding material distribution density of the transition section 132 increases in the direction closer to the boundary line 1103. With this arrangement, the main body 131 primarily shields against appearance defects at the boundary line 1103; while the transition section 132 acts as a transition, resulting in more uniform heating and light distribution, thus more effectively preventing defects such as refraction, rainbow stripes, and bright lines, thereby improving the overall product quality.
[0062] For example, the shape of the transition section 132 can be flexibly adjusted and set according to actual needs, such as being rectangular, curved, or other irregular shapes. Furthermore, the transition section 132 may include a plurality of shielding blocks 1321 arranged in an array, the shapes of which may be circular, elliptical, polygonal, or other regular and irregular shapes. Additionally, the density of the shielding blocks 1321 increases along the direction close to the boundary line 1103, thereby increasing the distribution density of the shielding material in the transition section 132.
[0063] The increased density of the occlusion block 1321 can be achieved in the following way:
[0064] For example, this can be achieved by adjusting the number of shielding blocks 1321 at different locations. Specifically, the number of shielding blocks 1321 near the boundary line 1103 is greater than the number of shielding blocks 1321 far from the boundary line 1103. In other words, the number of shielding blocks 1321 arranged per unit area is increased along the direction close to the boundary line 1103.
[0065] For example, when the number of occlusion blocks 1321 at different locations remains basically the same, this can be achieved by adjusting the size of the occlusion blocks 1321 at different locations. Specifically, the area of the occlusion blocks 1321 closer to the boundary line 1103 is larger than the area of the occlusion blocks 1321 farther from the boundary line 1103. In other words, the area of the occlusion blocks 1321 increases along the direction closer to the boundary line 1103.
[0066] Please see Figure 3For example, the distance between the boundary line 1103 and the contour edge 1301 is D. Optionally, 3mm ≤ D ≤ 50mm. Specifically, D is, for example, 3mm, 5mm, 10mm, 12mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm or 50mm, etc.
[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 the actual needs. There is no limitation here, as long as the defects such as refraction, rainbow stripes, and bright lines at the boundary line 1103 can be blocked.
[0068] During the production process, the positional tolerance of the first shielding layer 13 is approximately ±1.5mm, and the positional tolerance of the coating layer 12 is also approximately ±1.5mm. Therefore, the lower limit of the spacing D is set to 3mm. Furthermore, the upper limit of the spacing D mainly depends on factors such as the coefficient of thermal expansion and reflectivity of the coating area 1101 and the viewing area 1102 during the production process, resulting in the width of an optically defective region at the boundary line 1103. The width of this defective region is typically, for example, 20mm to 50mm. Therefore, setting the upper limit of the spacing D to 50mm is sufficient; there is no need to set the spacing D greater than 50mm, which would reduce the area of the viewing area 1102.
[0069] It should be noted that, in this embodiment, the length direction refers to, for example, the extension direction of the boundary line 1103, and the width direction refers to, for example, the direction perpendicular to the boundary line 1103 and parallel to the first masking layer 13. Correspondingly, the width of the first masking layer 13 refers to the distance between the two contour edges 1301.
[0070] Please see 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 coated area 1101 is located above the heads of the driver and passengers, serving a sun protection function. Optionally, the ratio of the area of the coated area 1101 to the area of the glass body 11 is, but not limited to, 20% to 40%, specifically, for example, 20%, 22%, 25%, 30%, 35%, or 40%, etc., which can be flexibly adjusted and set according to actual needs. In this way, the size of the coated area 1101 is appropriately set. On the one hand, the area of the coated area 1101 is large enough to ensure that the heads of the driver and passengers are shielded, effectively cooling and protecting them from the sun; on the other hand, the area of the coated area 1101 is small enough to increase the area of the field of vision 1102, thereby giving the driver and passengers a larger field of vision 1102 area.
[0072] For example, the field of vision area 1102 is located in front of the driver and passengers to ensure that they have a clear view. Optionally, the area of the field of vision area 1102 is larger than the area of the coating area 1101. The ratio of the area of the field of vision area 1102 to the area of the glass body 11 is 60% to 80%, specifically, for example, 60%, 62%, 65%, 70%, 75%, or 80%, etc., which can be flexibly adjusted and set according to actual needs.
[0073] In one embodiment, the field of view 1102 includes an image acquisition area 1104 corresponding to the camera position, and the shortest distance S between the boundary line 1103 and the image acquisition area 1104 is ≥ 10mm. Thus, a larger shortest distance S between the boundary line 1103 and the image acquisition area 1104 avoids defects such as refraction, rainbow stripes, and bright lines at the image acquisition area 1104 when the distance S is too small. This improves the image quality captured by the camera and prevents the captured image from being affected by the product appearance at the boundary line 1103.
[0074] Based on the aforementioned embodiments, S ≤ 100 mm. Specifically, S can be, 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, etc.
[0075] Please see 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 field of view 1102, and 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 surrounding the image acquisition area 1104. Alternatively, in some embodiments, the second shielding layer 14 may only be surrounding 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 onto the glass body 11 in a direction perpendicular to the glass body 11, so as 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 may include, but is not limited to, various regular and irregular shapes such as trapezoids, triangles, rectangles, and ellipses. The specific shape can be flexibly adjusted and set according to actual needs, and is not limited here.
[0079] The material of the second shielding layer 14 can also be a dark printed layer or a dark polymer film that is the same as that of the first shielding layer 13, which will not be elaborated here.
[0080] It should be noted that the glass body 11 can be either a single pane of glass or a laminated glass, and the specific configuration can be flexibly adjusted and configured according to actual needs. Since laminated glass has greater rigidity, this embodiment will specifically use a laminated glass glass body 11 as an example for detailed explanation, but it is not limited to this.
[0081] Please see 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 facing away from each other, with the first surface 1111 facing the external environment. The second glass plate 112 has a third surface 1121 and a fourth surface 1122 facing away from each other, with the fourth surface 1122 facing the internal environment. The adhesive layer 113 is disposed between the first glass plate 111 and the second glass plate 112. A coating layer 12 is disposed on at least one of the second surface 1112, the third surface 1121, and the fourth surface 1122, and a 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 component 10 installed on a vehicle as an example, the external environment is, for example, the outside of the vehicle, and the internal environment is, for example, the inside of the vehicle.
[0083] Please see Figure 3 For example, the first shielding layer 13 is disposed on the second surface 1112. Thus, since the glass body 11 is arc-shaped, when the first shielding layer 13 is disposed on the second surface 1112, especially when the first shielding layer 13 is a printed layer printed on the second surface 1112, it can meet the process requirements and prevent the roller from contacting the printed layer and causing damage to the first shielding layer 13.
[0084] Please see Figure 3 For example, the coating layer 12 is disposed on the second surface 1112 or the third surface 1121. With this arrangement, the coating layer 12 is located in the area between the first glass plate 111 and the second glass plate 112, and is not exposed, so as not to be damaged.
[0085] Please see Figure 3In one specific 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 printing layer is first printed on the second surface 1112 to obtain the first shielding layer 13, and then the coating layer 12 is obtained by coating the coating area 1101 of the second surface 1112. Thus, as shown in experiments, it can effectively prevent defects such as refraction, rainbow stripes, and bright lines that appear at the boundary line 1103, thereby improving the value of the product.
[0086] The glass assembly 10 in this application can eliminate / reduce product appearance defects at the boundary line 1103, thereby improving the functionality of the glass assembly 10, such as: dimming, heat insulation, sound insulation, etc.; and the product appearance is no worse than the original configuration, thus bringing a good experience to drivers and passengers, such as: comfort, safety, etc.
[0087] Please see 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, and is aligned with the first shielding layer 13 along the thickness direction of the glass body 11. The shapes of the third shielding layer 15 and the first shielding layer 13 correspond. Thus, the third shielding layer 15 also covers the boundary line 1103, and can shield product appearance defects at the boundary line 1103, better preventing defects such as refraction, rainbow stripes, and bright lines.
[0088] It should be noted that the third masking layer 15 can also be a dark printing layer or a dark polymer film that is the same as the first masking layer 13. The specific settings can be flexibly adjusted and set according to actual needs, and will not be elaborated here.
[0089] Of course, as an alternative, the third occlusion layer 15 can also be omitted, for example... Figure 3 , Figure 6 or Figure 7 As shown.
[0090] Please see Figures 3 to 8 For example, the glass assembly 10 also includes a fourth shielding layer 16. The fourth shielding layer 16 is disposed at the outer peripheral edge of the glass body 11, and can be disposed on at least one of the second surface 1112, the third surface 1121, and the fourth surface 1122, depending on actual needs. See, for example... Figure 3 and Figure 4 The fourth shielding layer 16 is disposed on the second surface 1112; for example, see [reference needed]. Figure 5 and Figure 6 The fourth shielding layer 16 is disposed on the fourth surface 1122; for example, see [reference needed]. Figure 7 and Figure 8 Both the second surface 1112 and the fourth surface 1122 are provided with a fourth shielding layer 16. The fourth shielding layer 16 serves to block light and forms a black edge on the outer periphery of the glass body 11, which serves to block light 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 masking layer 16 can also be a dark printing layer or a dark polymer film that is the same as the first masking layer 13. The specific settings can be flexibly adjusted and set according to actual needs, and will not be elaborated here.
[0092] For example, the first glass plate 111 may be, but is not limited to, tempered glass, more specifically, heat-tempered glass. The thickness of the first glass plate 111 may be, but is not limited to, 1.6mm to 2.3mm, specifically, 1.6mm, 1.8mm, 1.9mm, 2mm, 2.2mm, or 2.3mm, etc. Furthermore, the color of the first glass plate 111 may be, for example, green glass, white glass, etc., and can be flexibly adjusted and set according to actual needs.
[0093] The second glass plate 112 is configured similarly to the first glass plate 111. For example, the second glass plate 112 may be, but is not limited to, tempered glass, more specifically, heat-tempered glass. The thickness of the second glass plate 112 may be, but is not limited to, 1.6mm to 2.3mm, specifically, 1.6mm, 1.8mm, 1.9mm, 2mm, 2.2mm, or 2.3mm, etc. Furthermore, the color of the second glass plate 112 may be, for example, green glass, white glass, etc., and can be flexibly adjusted and set 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 with at least one of the functions of sound insulation, heat insulation, and light adjustment. Optionally, the adhesive layer 113 can be a single layer or a multi-layer composite adhesive layer, which can be flexibly adjusted and set according to actual needs. The thickness of the adhesive layer 113 includes, but is not limited to, 0.05mm to 0.76mm, with specific thicknesses such as 0.05mm, 0.38mm, and 0.76mm.
[0095] Optionally, the adhesive layer 113 may be made of PVB, EVA, TPU or SGP materials.
[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 transparent material. Alternatively, the adhesive layer 113 can be partially transparent, with the visible light transmittance of the transparent portions exceeding 90%, or even reaching 95% or more, while the visible light transmittance of the opaque portions is less than 50%, specifically less than 35%, 20%, 10%, or 3%, etc. The opaque portions can be colored, including but not limited to green, blue, gray, and transitional colors, which can be flexibly adjusted and set according to actual needs.
[0097] As an example, the portion of the adhesive layer 113 corresponding to the viewing area 1102 is made of transparent material, thereby ensuring a relatively clear view of the viewing area 1102; the portion of the adhesive layer 113 corresponding to the coating area 1101 is made of non-transparent material, thereby blocking light and achieving an anti-scalding effect. The visible light transmittance of the transparent material is, for example, greater than 90%, or even exceeding 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%, etc.
[0098] Please see Figures 1 to 3 In one embodiment, this embodiment also provides a means of transportation, including but not limited to automobiles, buses, cars, public transport vehicles, coaches, trucks, jeeps, trains, high-speed trains, etc. The means of transportation includes the glass assembly 10 of any of the above embodiments. The glass assembly 10 includes, but is not limited to, the vehicle's windshield, side windows, rear window, and sunroof, etc.
[0099] The aforementioned 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 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 field of vision 1102, the field of vision 1102 is clearer and easier for the driver and passengers to observe; in addition, the glass assembly 10 also includes a first shielding layer 13, which covers the boundary line 1103. The two contour edges 1301 of the first shielding layer 13 are respectively set in the coating area 1101 and the field of vision 1102. In this way, the shielding property of the first shielding layer 13 can indirectly eliminate or reduce product appearance defects at the boundary line 1103, prevent defects such as refraction, rainbow stripes, and bright lines, thereby improving the value of the product and providing a comfortable field of vision for the driver and passengers, thus improving the driving safety factor.
