The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present disclosure.

The terms "first," "second," and the like in the description and claims of the present application and in the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments, in case at least two embodiments are combined together without contradiction.

Referring to fig. 1, the present application provides a Vehicle 1, and the Vehicle 1 may be, but is not limited to, a passenger car, a multi-Purpose Vehicle (MPV), a Sport Utility Vehicle (SUV), an Off-Road Vehicle (ORV), a pickup truck, a minibus, a van, and the like.

The vehicle 1 includes a frame 10 and a window glass 20, and the window glass 20 is mounted on the frame 10. The window glass 20 is used for meeting the requirements of lighting and ventilation in the vehicle and the visual field of people in the vehicle. The window glass 20 may be, but is not limited to, a front windshield, a rear windshield, a door window, a quarter window, a sunroof, or the like. The shape of the window glass 20 may be substantially triangular, rectangular, trapezoidal, polygonal with the number of remaining sides being four or more, or the like.

Referring to fig. 2 and 3, the window pane 20 has a first major surface X1 and a second major surface X2 facing away from each other. The first main surface X1 faces the interior of the vehicle 1. The second main surface X2 faces the outside of the vehicle 1. Wherein the window pane 20 is preferably a bent glass, the first main surface X1 being concave and the second main surface X2 being convex. A functional layer 212 is provided on the first main surface X1. It will be appreciated that the vehicle 1 is inevitably subjected to adverse conditions during travel, such as the branches of a tree passing over the vehicle body. If the functional layer 212 is provided on the second main surface X2 of the window glass 20, it is easily scratched by foreign objects such as branches, and the functional layer itself fails. Therefore, the provision of the functional layer 212 to the first major surface X1 of the window pane 20 may reduce or avoid the possibility of damage by foreign objects.

For the convenience of the following description, the direction in which the first main surface X1 points toward the second main surface X2 (or the second main surface X2 points toward the first main surface X1) is defined as a light transmission direction in which light can pass through the window glass 20. For the following description related to the light transmission direction, refer to the description herein.

The following describes in detail the window glass 20 in the vehicle 1 provided in the above embodiment with reference to the drawings.

Referring to fig. 2 and 3, an embodiment of the present application provides a window glass 20, where the window glass 20 includes a light-transmitting plate 210 and a covering structure 220. The light-transmitting plate 210 includes a light-transmitting member 211, a functional layer 212, and a shielding layer 214. The light transmissive member 211 has a first major surface X1, a second major surface X2, and a side surface X3. The shielding layer 214 is disposed on the first main surface X1 in a closed ring shape and is close to the periphery of the light-transmitting member 211. The functional layer 212 is disposed on the first main surface X1 and covers at least part of the masking layer 214. The edge covering structure 220 is fixed on the periphery of the light-transmitting piece 211 and covers at least the first main surface X1.

Specifically, the light-transmitting member 211 is made of a transparent material, and can transmit light. The first main surface X1 and the second main surface X2 of the light-transmitting member 211 are disposed opposite to each other, and the side surface X3 is connected to the first main surface X1 and the second main surface X2 in a bent manner and is located at an edge of the light-transmitting member 211.

Optionally, the light-transmitting member 211 is a single piece of tempered glass, laminated glass, a PMMA (polymethyl methacrylate) transparent plate, or a PC (polycarbonate) transparent plate.

The shielding layer 214 is in a closed ring shape, is connected to the first main surface X1 and is disposed at an edge of the light-transmitting member 211, that is, the shielding layer 214 is disposed along the edge of the light-transmitting member 211, thereby forming a closed ring shape. The shielding layer 214 is used to shield light, so that the window glass 20 forms a light transmitting region a1 and a light shielding region a2 in the light transmitting direction. Light may pass through the light-transmitting region a1 without passing through the light-shielding region a2 or only a small amount of light may pass through the light-shielding region a 2.

Optionally, the material of the shielding layer 214 is selected from black ceramic ink, brown ceramic ink, gray ceramic ink, black ultraviolet ink, brown ultraviolet ink, or gray ultraviolet ink.

The functional layer 212 has a specific function, which may be to filter infrared rays, ultraviolet rays, fingerprint prevention, fog prevention, etc. A portion of the functional layer 212 is attached to the side of the shielding layer 214 facing away from the light transmissive member 211, and another portion of the functional layer 212 is attached to the first major surface X1, it being understood that the functional layer 212 attached to the first major surface X1 is surrounded by the annular shielding layer 214. From another perspective, the functional layer 212 covers the whole light-transmitting area a1 and at least part of the light-shielding area a2, the functional layer 212 covering the light-transmitting area a1 is connected to the light-transmitting member 211, and the functional layer 212 covering the light-shielding area a2 is connected to the shielding layer 214. It will be appreciated that since all of the light transmitting area a1 is covered by the functional layer 212, light passing through the window pane 20 passes through the functional layer 212, thereby fully performing the specific function of the functional layer 212.

Optionally, the functional layer 212 is a sol-gel coating, an anti-fog coating or an anti-fingerprint coating. Wherein at least one of an ultraviolet absorber, an infrared absorber and a blue light absorber is added into the sol-gel coating. The ultraviolet absorber, the infrared absorber and the blue absorber are used for absorbing ultraviolet, infrared and blue light respectively. The antifogging coating comprises water-absorbent resin (epoxy resin, polyurethane resin, acrylic resin and the like) or perfluoropolyether siloxane. The antifogging coating is used for realizing an antifogging function. The anti-fingerprint coating comprises perfluoropolyether siloxane. The anti-fingerprint coating is used for realizing an anti-fingerprint function.

The edge-covering structure 220 is disposed along the periphery of the light-transmitting member 211, so as to be in a closed ring shape. The edge covering structure 220 is used for protecting the edge of the light-transmitting member 211. Optionally, the material of the edge covering structure 220 may be, but is not limited to, a polyolefin thermoplastic elastomer (including polypropylene, rubber, other fillers, etc.), polyvinyl chloride (including polyvinyl chloride resin, plasticizer, calcium-zinc mixed stabilizer, other fillers, etc.), and other flexible glues with elasticity.

In the prior art, the shielding layer is annular, the functional layer is surrounded in the region surrounded by the shielding layer, and orthographic projections of the shielding layer and the functional layer on the light-transmitting member do not overlap, and in order to form the arrangement form, an additional process is usually required for implementation. Specifically, in one manufacturing method (film removal method), a functional layer is first formed on the surface of a light-transmitting member, then the peripheral edge of the functional layer is removed to expose an annular region, and finally a shielding layer is formed in the annular region; in another manufacturing method (masking method), an annular mask is firstly used to cover the surface of the light-transmitting member, then a functional layer is formed in the area of the light-transmitting member not covered by the annular mask, the mask is removed after the functional layer is formed, and finally a masking layer is formed in the area previously covered by the mask. As can be seen from the above two preparation methods, in order to avoid overlapping of the shielding layer and the functional layer, a film removing process and a shielding process are required, which obviously increases the preparation time. In addition, due to factors such as manufacturing tolerance, the inner edge of the shielding layer and the outer edge of the functional layer cannot be completely overlapped by the existing preparation process, that is, a gap is likely to exist between the shielding layer and the functional layer, so that more than two visual separation lines are generated at the boundary of the shielding layer and the functional layer.

In the present application, the shielding layer 214 and the functional layer 212 are disposed on the first surface of the light-transmitting member 211, and the functional layer 212 covers at least a portion of the shielding layer 214, that is, the orthographic projection of the shielding layer 214 and the functional layer 212 on the light-transmitting member 211 is overlapped. Therefore, the structure of the vehicle window glass 20 provided by the application is formed, and a film removing process or a shielding process in the prior art is not needed, so that the preparation time of the vehicle window glass 20 can be reduced, and the cost is reduced. Further, the shielding layer 214 and the functional layer 212 are also directly connected to the light-transmitting member 211, so that the connection stability between the shielding layer 214, the functional layer 212, and the light-transmitting member 211 can be ensured. In addition, the functional layer 212 covers at least part of the shielding layer 214, so that a visual dividing boundary line at the boundary between the shielding layer 214 and the functional layer 212 can be avoided, and moreover, part of the functional layer 212 extends to the shielding layer 214, so that a specific function, such as an anti-fingerprint function, is added to the surface of the shielding layer 214 positioned in the vehicle.

Referring to fig. 3, optionally, the edge-covering structure 220 covers the first main surface X1, the side surface X3 and the second main surface X2. Specifically, the wrapping structure 220 includes a first wrapping portion 221, a second wrapping portion 222, and a third wrapping portion 223 that are sequentially bent and connected. The first wrapper 221 and the third wrapper 223 are oppositely disposed. The first wrapping portion 221 covers the first main surface X1 of the light-transmitting member 211. The second wrapping portion 222 covers the side surface X3 of the light-transmitting member 211. The third wrapping portion 223 covers the second major surface X2 of the light-transmitting member 211. It is understood that the first main surface X1, the side surface X3, and the second main surface X2 are all wrapped in three sides, so that the edge of the light-transmitting member 211 is all protected and thus is not easily damaged.

Referring to fig. 4, optionally, the edge covering structure 220 covers the first main surface X1 and the side surface X3. Specifically, the wrapping structure 220 may include a first wrapping portion 221 and a second wrapping portion 222 that are connected in a bending manner. The first wrapping portion 221 covers the first main surface X1 of the light-transmitting member 211. The second wrapping portion 222 covers the side surface X3 of the light-transmitting member 211.

Optionally, the thickness of the shielding layer 214 is 5 to 40 micrometers. The thickness of the functional layer 212 is 3-25 micrometers.

Optionally, the visible light transmittance of the light-transmitting member 211 is 20% to 95%. The functional layer 212 has a visible light transmittance of 50% or more. The shielding layer 214 has a visible light transmittance of 5% or less.

Referring to fig. 3 and fig. 4, optionally, the functional layer 212 covers the whole of the shielding layer 214, and at least a part of the edge covering structure 220 is disposed on a side of the functional layer 212 facing away from the shielding layer 214. That is, all of the shielding layer 214 is directly connected to the functional layer 212, and the first wrapping portion 221 of the edge-covering structure 220 covers the side of the functional layer 212 facing away from the shielding layer 214.

Referring to fig. 5, optionally, the functional layer 212 covers a portion of the shielding layer 214, and the edge covering structure 220 covers another portion of the shielding layer 214. That is, orthographic projections of the first wrapping portion 221 and the functional layer 212 of the edge-covering structure 220 on the light-transmitting member 211 do not overlap, a part of the shielding layer 214 is directly connected to the first wrapping portion 221, and another part of the shielding layer 214 is directly connected to the functional layer 212.

Referring to fig. 6, optionally, the functional layer 212 covers a portion of the shielding layer 214, the edge covering structure 220 covers another portion of the shielding layer 214, and at least a portion of the edge covering structure 220 is disposed on a side of the functional layer 212 facing away from the shielding layer 214. That is, the orthographic projection of the first wrapping portion 221 of the edge-covering structure 220 on the functional layer 212 exceeds the range of the functional layer 212, and one part of the shielding layer 214 is directly connected to the first wrapping portion 221, and the other part of the shielding layer 214 is directly connected to the functional layer 212.

Referring to fig. 7, the light-transmitting plate 210 further includes an adhesive layer 213, and the adhesive layer 213 includes an inner adhesive portion 2131. The inner bonding portion 2131 faces the first main surface X1 of the light-transmitting member 211, and is used for fixing at least part of the edge-covering structure 220 to the first main surface X1, that is, the inner bonding portion 2131 is used for bonding the first wrapping portion 221 to the functional layer 212.

Referring to fig. 7, the inner adhesive portion 2131 includes an activator layer 213b and a primer layer 213 a. The primer layer 213a is disposed opposite to the functional layer 212. The activator layer 213b is disposed between the functional layer 212 and the primer layer 213 a. The primer layer 213a is adhered to the functional layer 212 through the activator layer 213 b.

The outer adhesive portion 2133 is used for fixing at least part of the edge covering structure 220 (i.e., the third wrapping portion 223) to the second main surface X2 of the light-transmitting member 211. The side adhesive portions 2132 and the outer adhesive portions 2133 are formed by laminating an activator layer 213b, a primer layer 213a and a primer layer 213a, and the activator layer 213b is closer to the light-transmitting member 211 than the primer layer 213 a.

Referring to fig. 8, another embodiment of the present application provides a window glass 20, where the window glass 20 includes a transparent plate 210, and the transparent plate 210 includes a transparent member 211, a functional layer 212, and an adhesive layer 213. The adhesive layer 213 includes an inner adhesive portion 2131. The functional layer 212 and the inner adhesive portion 2131 are sequentially disposed on the same side of the light-transmitting member 211. The orthographic projection of the inner adhesive portion 2131 on the functional layer 212 falls within the region of the functional layer 212. Wherein the functional layer 212 comprises a binding composition. The functional layer 212 is bonded to the light-transmitting member 211 and the inner bonding portion 2131 by the bonding component. In other words, the light-transmitting member 211, the functional layer 212, and the inner adhesive portion 2131 are sequentially stacked, and opposite sides of the functional layer 212 are respectively adhered to the light-transmitting member 211 and the inner adhesive portion 2131, so that the integrity or the integrity of the window glass 20 can be ensured.

The light-transmitting member 211 can transmit light, and the light-transmitting member 211 can be, but not limited to, glass (e.g., tempered glass, laminated glass, semi-tempered laminated glass, etc.), plastic, etc. The shape of the light-transmitting member 211 may be substantially triangular, rectangular, trapezoidal, polygonal with the number of remaining sides greater than or equal to four, or the like. In the following embodiments, the light-transmitting member 211 is exemplified as glass.

Alternatively, the binding component in the functional layer 212 is a silane compound. When the light-transmitting member 211 is glass, the silane compound may chemically react with the glass, thereby firmly bonding the functional layer 212 to the light-transmitting member 211.

Referring to fig. 9, the inner adhesive portion 2131 includes an activator layer 213b and a primer layer 213 a. The primer layer 213a is disposed opposite to the functional layer 212.

Optionally, the material composition of the activator layer 213b includes volatile alcohol (for cleaning oil stain, fingerprint, etc. on the surface of the functional layer 212) and silane which can activate the primer layer 213 a. The material composition of the primer layer 213a includes an adhesive (e.g., a resin-based adhesive) for achieving an adhesive effect and a curing agent (e.g., a polycyanate curing agent) for achieving curing of the primer layer 213 a. The adhesive in the primer layer 213a may be compatible with the silane compound in the functional layer 212, that is, the adhesive in the primer layer 213a and the silane compound of the functional layer 212 may react, so that the primer layer 213a and the functional layer 212 form a firm adhesion effect.

Optionally, the functional layer 212 further includes at least one of an ultraviolet absorber and an infrared absorber. In other words, the functional layer 212 may contain both the ultraviolet absorber and the infrared absorber, or may contain only one of the ultraviolet absorber and the infrared absorber. Wherein the ultraviolet absorber is used for absorbing ultraviolet rays, and the infrared absorber is used for absorbing infrared rays. Therefore, the functional layer 212 has an ultraviolet and/or infrared ray shielding function, which is advantageous for protecting passengers in the vehicle from ultraviolet and infrared rays.

Alternatively, when the material of the functional layer 212 contains an ultraviolet absorber, the ultraviolet transmittance of the window glass 20 is less than 1%.

Alternatively, when the material of the functional layer 212 contains an infrared absorber, the infrared transmittance of the window glass 20 is less than 30%.

Optionally, the functional layer 212 is made of a transparent material, which does not affect the visibility of the light-transmitting plate 210, and the visible light transmittance is greater than or equal to 70%.

The functional layer 212 may be formed by, but not limited to, a spray coating process.

Optionally, the functional layer 212 may be cured at a high temperature after being formed, and the functional layer 212 has a certain hardness after being cured at a high temperature, where the hardness is higher than pencil hardness H7.

Optionally, the thickness of the functional layer 212 ranges from 3 μm to 9 μm. The thickness of the functional layer 212 may or may not be equal everywhere.

Referring to fig. 9, the window glass 20 further includes a shielding layer 214 for shielding light. The shielding layer 214 is disposed between the light-transmitting member 211 and the functional layer 212 in a closed ring shape along the periphery of the light-transmitting member 211, that is, the shielding layer 214 is disposed along the edge of the light-transmitting member 211 to form a closed ring shape. The closed loop shape may be a substantially rectangular loop shape, a triangular loop shape, or the like. In the light transmission direction, the area covered by the shielding layer 214 is a light shielding area a2, and the area not covered by the shielding layer 214 is a light transmission area a 1. Light may pass through the light-transmitting region a1 without passing through the light-shielding region a2 or only a small amount of light may pass through the light-shielding region a 2. The material of the shielding layer 214 may be, but is not limited to, black ceramic.

Further, referring to fig. 8 and 9, the functional layer 212 covers the entire light-transmitting area a1 and at least a part of the light-shielding area a 2. The functional layer 212 covering the light transmitting area a1 is bonded to the light transmitting member 211. It is understood that since all of the light transmitting area a1 is covered by the functional layer 212, light passing through the window pane 20 passes through the functional layer 212, thereby fully performing the filtering function of the functional layer 212, i.e., the functional layer 212 can absorb at least a portion of the uv and/or ir light in the filtered light.

Referring to fig. 9, an orthogonal projection of the inner adhesive portion 2131 on the shielding layer 214 at least partially falls within a range of the shielding layer 214, that is, a projection of the inner adhesive portion 2131 and the shielding layer 214 on the light-transmitting member 211 at least partially overlap. Wherein the at least part means: the orthographic projection of the internal adhesive part 2131 on the shielding layer 214 is totally within the range of the shielding layer 214, or the orthographic projection part of the internal adhesive part 2131 on the shielding layer 214 is within the range of the shielding layer 214, and the other part of the orthographic projection part is out of the range of the shielding layer 214.

It can be understood that, since the inner adhesive portion 2131 is farther away from the light-transmitting member 211 than the shielding layer 214, during the process of the external light emitted from the second main surface X2 to the first main surface X1 of the window glass 20, at least a portion of the inner adhesive portion 2131 is shielded by the shielding layer 214, and the shielded inner adhesive portion 2131 can be prevented from being directly irradiated by the external light. Therefore, in the arrangement of the present embodiment, at least part of the inner adhesive portion 2131 can be protected by the shielding layer 214, and the inner adhesive portion 2131 is prevented from being damaged by direct irradiation of strong light outside the vehicle, and the adhesion performance of the inner adhesive portion 2131 itself can be kept in a good state.

Referring to fig. 9, the window pane 20 further includes a covering 220, and the covering 220 includes a first covering portion 221, a second covering portion 222, and a third covering portion 223. The first wrapper 221 and the third wrapper 223 are oppositely disposed. The first wrapping portion 221, the second wrapping portion 222 and the third wrapping portion 223 are sequentially bent and connected and jointly enclose a receiving space a 3. The receiving space a3 is used for receiving the periphery of the light-transmitting plate 210. In other words, the edge 220 is a closed ring shape and wraps the periphery of the light-transmitting plate 210. The third wrapping portion 223 is bonded to the primer layer 213a of the inner bonding portion 2131.

The material of the covering 220 may be, but not limited to, polyolefin thermoplastic elastomer (including polypropylene, rubber, other fillers, etc.), polyvinyl chloride (including polyvinyl chloride resin, plasticizer, calcium-zinc mixed stabilizer, other fillers, etc.), and other flexible glue with elasticity.

Further, referring to fig. 10, the adhesive layer 213 may further include a side adhesive portion 2132 and an outer adhesive portion 2133. The outer adhesive portion 2133 and the inner adhesive portion 2131 are provided to face each other. The outer adhesive portion 2133, the side adhesive portions 2132, and the inner adhesive portion 2131 are sequentially connected by bending. The outer adhesive portion 2133 is adhered between the third wrapping portion 223 and the light-transmitting member 211. The side adhesive part 2132 is adhered between the second wrapping part 222 and the light-transmitting member 211. In short, the adhesive layer 213 and the covering edge 220 have the same bent shape, and the covering edge 220 and the light-transmitting member 211 are adhered by the adhesive layer 213. Note that the side adhesive portions 2132 and the outer adhesive portions 2133 are each formed by laminating a primer layer 213a and an activator layer 213b, and the activator layer 213b is provided between the primer layer 213a and the light-transmitting member 211.

Further, the third wrapping portion 223 and the transparent plate 210 are bonded together by the outer bonding portion 2133 to have a bonding width H3. The second wrapping portion 222 and the transparent plate 210 are bonded together by the side bonding portions 2132 to have a bonding width H2. The first wrapping portion 221 and the light-transmitting plate 210 are bonded together by the inner bonding portion 2131 to have a bonding width H1. The sum of H3, H2, and H1 is greater than or equal to 8mm, that is, the sum of the bonding widths of the third wrapping portion 223, the second wrapping portion 222, and the first wrapping portion 221 to the light-transmitting plate 210 is greater than or equal to 8 mm.

The third wrapping portion 223 and the transparent plate 210 are bonded by the outer bonding portion 2133 with a bonding width H3 of 3mm or more, and/or the first wrapping portion 221 and the transparent plate 210 are bonded by the inner bonding portion 2131 with a bonding width H1 of 3mm or more.

Further, the shearing adhesive force of the light-transmitting plate 210 and the edge-covering 220 along the X-axis direction is greater than 0.5 Mpa. The tensile bonding force of the light-transmitting plate 210 and the edge-covering 220 along the Y-axis direction is larger than 100N/50 mm.

Optionally, the light-transmitting plate 210 and the edge 220 are integrally injection molded, that is, the light-transmitting plate 210 is placed in a mold, then a molten plastic material is poured into the mold, and the edge 220 wrapping the periphery of the light-transmitting plate 210 is formed after cooling and curing.
