[0041] Referring to FIGS. 1 to 3 , an anti-fog glass provided in an embodiment of the present application includes a glass body 100 , a photovoltaic cell film 200 , and a heating layer 300 . The glass body 100 includes an inner glass layer 110 , a first adhesive film layer 120 , a second adhesive film layer 130 , and an outer glass layer 140 , which are stacked in sequence. The photovoltaic cell film 200 is arranged between the first adhesive film layer 120 and the second adhesive film layer. The heating layer 300 is arranged on a side of the first adhesive film layer 120 close to the inner glass layer 110 . The photovoltaic cell film 200 is electrically connected to the heating layer 300 , wherein the heating layer 300 is misaligned with the photovoltaic cell film 200 along the extension direction of the glass body 100 . The extension direction of the glass body 100 is perpendicular to the thickness direction of the glass body 100 .

[0042] Specifically, the glass body 100 is the front windshield of the vehicle, and has a transmission area 150 and a sunshade area 160 on the glass body 100; the photovoltaic cell film 200 is located in the sunshade area 160, and the heating layer 300 is located in the transmission area 150. The camera in the vehicle is used to shoot the image outside the vehicle through the transmission area 150, wherein the inner glass layer 110 is located on the side close to the inside of the vehicle, and the outer glass layer 140 is located on the side outside the vehicle.

[0043] In this embodiment, the photovoltaic cell film 200 is electrically connected to the heating layer 300, that is, the photovoltaic cell film 200 can generate electricity for the heating layer 300, thereby reducing the power consumption of the power part in the vehicle. The heating layer 300 is arranged on a side close to the inner glass layer 110. After the heating layer 300 is energized, it can heat the inner glass layer, thereby preventing the inner layer of the glass from fogging. In addition, the photovoltaic cell film 200 is fixed by the first adhesive film layer 120 and the second adhesive film layer 130. The photovoltaic cell film 200 has a light transmittance of 10%-50% in the visible light region, so it can block part of the light directly shining on the driver's face to prevent glare. The heating layer 300 is misaligned with the photovoltaic cell film 200, so that the camera can shoot the image outside the vehicle through the transmission area 150 to ensure the image effect obtained.

[0044] 3 , in some embodiments, the heating layer 300 includes a plurality of heating wires 310 arranged in sequence, and the heating wires 310 are in a wavy structure.

[0045] In this embodiment, the heating wire 310 has a wavy structure, which can avoid deformation and breakage of the heating wire 310 due to thermal expansion and contraction, and increase the length of the heating wire 310, that is, increase the heated area of ​​the film, making the temperature in the area more uniform.

[0046] Furthermore, the diameter of the heating wire 310 is less than or equal to 15 μm, and the ratio of the distance L between two adjacent crests of the heating wire 310 to the height H of the crest is in the range of 1-2.

[0047] In this embodiment, when the diameter of the heating wire 310 is less than or equal to 15 μm, it is invisible to the naked eye. However, due to the different expansion coefficients of the heating wire 310 made of metal and the first adhesive film layer 120, the heating wire 310 is easily broken under long-term temperature changes. Therefore, the heating wire 310 of the present application has a wavy structure, which can buffer the deformation caused by thermal expansion and contraction and avoid the heating wire 310 from breaking.

[0048] The ratio of the distance L between two adjacent wave crests of the heating wire 310 to the height H of the wave crest is in the range of 1-2. If the ratio is too large, that is, the distance between two adjacent wave crests is relatively large, the contact area between the heating wire 310 and the first adhesive film layer 120 is small, which may cause uneven heating of the first adhesive film layer 120 and cause optical distortion; if the ratio is too large, that is, the distance between two adjacent wave crests is relatively small, which may easily block the camera and affect the camera's function of capturing pixels.

[0049] In some embodiments, the minimum distance ΔH between two adjacent heating wires 310 is 1 mm-2 mm.

[0050] Specifically, when the minimum distance △H between two adjacent heating wires 310 is less than 1mm, it is easy to block the camera, affecting the camera's pixel capture function. When the minimum distance △H between two adjacent heating wires 310 is greater than 2mm, the contact area between the heating wires 310 and the first adhesive film layer 120 is small, which easily causes uneven heating of the first adhesive film layer 120, causing optical distortion.

[0051] In some embodiments, at least part of the periphery of the transmission area 150 has a first ink area 320, and a plurality of heating wires 310 are interconnected by a bus bar, and the bus bar is arranged in the first ink area 320; at least part of the periphery of the inner glass layer 110 and the outer glass layer 140 respectively has a second ink area 170, and the photovoltaic cell film 200 has lead wires, which are located in the second ink area 170 and are electrically connected to the bus bar.

[0052] In this embodiment, the busbars of the heating layer 300 are hidden in the first ink area 320, and the lead wires of the photovoltaic cell film 200 are hidden in the second ink area 170, which is beneficial to improving the aesthetics of the anti-fog glass.

[0053] The second ink area 170 completely wraps the periphery of the glass body 100, the first ink area 320 half wraps the transmission area 150, one end of the first ink area 320 is connected to the second ink area 170, and one end of the first ink area 320 away from the second ink area 170 is free of ink, that is, has an opening 171. The end of the bus bar is provided with a lead terminal 330, which extends into the second ink area 170 and is connected to the lead wire of the photovoltaic cell film 200.

[0054] Furthermore, the heating layer 300 includes a second base film layer and a metal grid disposed on the second base film layer, and the material of the second base film layer is the same as that of the first adhesive film layer. Thus, when the heating layer 300 is disposed in the transmission area 150, the second base film can be completely integrated with the first adhesive film layer 120, avoiding the appearance of a boundary between the heating layer 300 and the first adhesive film layer 120, that is, avoiding the appearance of a boundary at the position of the opening 171, which affects the appearance.

[0055] An embodiment of the present application discloses a method for manufacturing anti-fog glass, comprising the following steps:

[0056] Placing the photovoltaic cell film 200 between the first adhesive film layer 120 and the second adhesive film layer 130;

[0057] The heating layer is placed between the first adhesive film layer 120 and the inner glass layer 110;

[0058] The photovoltaic cell film 200 and the heating layer 300 are electrically connected.

[0059] In this embodiment, the photovoltaic cell film 200 is electrically connected to the heating layer 300 , that is, the photovoltaic cell film 200 can generate electricity for the heating layer 300 , thereby reducing the power consumption of the power part in the vehicle.

[0060] The manufacturing method of the heating layer 300 includes:

[0061] bonding the metal film to the first base film;

[0062] Processing a wavy pattern on the metal film to obtain a metal grid attached to the first base film;

[0063] The metal grid is transferred onto the second base film, and the second base film is made of the same material as the first adhesive film layer 120 .

[0064] In this embodiment, a metal grid is first processed on the first base film, and then the metal grid is transferred from the first base film to the second base film. The second base film is made of the same material as the first adhesive film layer 120, so that when the heating layer 300 is set in the transmission area 150, the second base film can be completely integrated with the first adhesive film layer 120, avoiding the formation of a boundary between the heating layer 300 and the first adhesive film layer 120, that is, avoiding the formation of a boundary at the position of the opening 171, which affects the appearance.

[0065] In some embodiments, the step of transferring the metal grid onto the second base film includes: bonding the second base film to a side of the metal grid away from the first base film, and heating and pressing the second base film by a roller press; and removing the first base film.

[0066] In this embodiment, a metal grid is first processed on the first base film, and then the second base film is bonded to the side of the metal grid away from the first base film, and the three bonded together are placed in a roller press. On the one hand, the heating of the roller press can press the metal grid into the second base film, and on the other hand, the heating of the roller press can facilitate the detachment of the first base film, so as to facilitate the transfer of the metal grid from the first base film to the second base film.

[0067] Specifically, the metal film includes but is not limited to a copper film and a silver film. The first base film may be a release film, and the release film includes but is not limited to PC, PET, PMMA, PI, and PP materials. The second base film and the first adhesive film layer 120 are made of PVB. The metal film and the first base film are bonded by a thermoplastic adhesive. When the temperature rises, the bonding effect of the thermoplastic adhesive decreases, so that after the metal grid is transferred to the second base film, the first base film can be removed by heating.

[0068] Methods for processing the wave-breaking pattern on the metal film include but are not limited to exposure etching, laser processing or chemical etching.

[0069] In some embodiments, after the step of removing the first base film, the following step is further included: coating a bonding layer on the surface of the metal grid on the second base film, wherein the bonding layer is used to bond the metal grid to the inner glass layer 110 .

[0070] Among them, the bonding layer is made of the same raw material as the second base film, and the specific steps of coating the bonding layer on the metal grid surface on the second base film include: dissolving the raw material of the bonding layer in a volatile solvent to obtain a solution, coating the solution on the surface of the second base film, and obtaining the heating layer 300 after heating.

[0071] In this embodiment, the raw materials of the bonding layer are dissolved in a volatile solvent, and then the dissolved liquid is coated on the surface of the pre-finished product of the heating layer 300, and then heated to evaporate the volatile solvent. The bonding layer is retained on the surface of the heating layer 300. When the heating layer 300 is set in the projection area, the metal grid of the heating layer 300 can fit well with the glass to prevent the generation of bubbles.

[0072] Specifically, the raw material of the adhesive layer and the raw material of the second base film are both polyvinyl butyral.

[0073] Polyvinyl butyral is dissolved in a volatile solvent to obtain a polyvinyl butyral solution. Coating the polyvinyl butyral solvent on the surface of the second base film helps the polyvinyl butyral to be evenly coated on the surface of the metal grid, further allowing the metal grid to better fit the glass.

[0074] Specifically, the volatile solvent includes anhydrous ethanol, wherein the volume fraction ratio of polyvinyl butyral to anhydrous ethanol is 1:10.

[0075] Of course, in other embodiments, the volatile solvent can also be methanol, ethanol, n-propanol, isopropanol, n-pentanol, benzyl alcohol, butanol, diacetone alcohol, propylene glycol ether / methyl ether / propyl ether, acetone, methyl ethyl ketone, cyclohexanone, dichloromethane, chloroform, methyl acetate, ethyl acetate, butyl acetate, acetic acid and other organic solvents, and the volatile solvent evaporates after heating.

[0076] In a specific embodiment, the steps of preparing the heating layer 300 include:

[0077] Step 1: Compounding the metal film with the PET base film through an adhesive;

[0078] Step 2: Processing the metal film into a wavy pattern through a mask etching process to obtain a metal grid attached to the PET base film;

[0079] Step 3: Laminating the metal grid with the PVB base film through an adhesive, with the metal grid close to the textured surface of the PVB base film;

[0080] Step 4: The PET base film, the metal grid and the PVB base film bonded together are passed through a roller press, wherein a heating chamber is provided in the roller press, the purpose of which is to soften the PET base film and the PVB base film, separate the metal grid from the PET base film, and embed the heating wire 310 into the softened PVB base film, thereby obtaining a heating layer 300 with the metal wire embedded in the PVB base film;

[0081] Step 5: dissolve polyvinyl butyral (raw material of PVB base film) in anhydrous ethanol to form a solution, and apply the solution on the metal grid of the heating layer 300 with a wire rod. Heat on a heating table after each application to accelerate the volatilization of the anhydrous ethanol, and apply again after drying. Repeat 3-5 times.

[0082] Step 6: Place the prepared heating layer 300 into a vacuum drying oven for further drying at a drying temperature of 50° C.

[0083] Step seven, spreading the dried heating layer 300 flat, vacuum packaging it, and refrigerating it to form the heating layer 300 .

[0084] In a specific embodiment, the method for processing anti-fog glass comprises the following steps:

[0085] Lay the first adhesive film layer 120 on the inner glass layer 110, cut the transmission area 150 on the first adhesive film layer 120, embed the heating layer 300 into the transmission area 150, and heat the peripheral side of the first transmission area 150 by an electric soldering iron so that the edge of the heating layer 300 is fused with the first adhesive film layer 120, and connect the lead terminal 330 to the bus bar of the heating layer 300;

[0086] Placing the photovoltaic cell film 200 in the sunshade area 160 and connecting the electrodes of the photovoltaic cell film 200 to the lead terminals 330;

[0087] Laying the second adhesive film layer 130 on the first adhesive film layer 120 and placing the outer glass layer 140 to complete the lamination;

[0088] The laminated anti-fog glass is subjected to initial high pressure operation to obtain a finished front windshield glass;

[0089] The photovoltaic cell film 200 has a light transmittance of 10%-50% in the visible light region. It is placed in the sunshade area 160 of the front windshield to block light from directly hitting the driver's face and prevent glare. The photovoltaic cell film 200 has a first transparent substrate and a second transparent substrate, and the transparent substrate is made of PET, PI, etc.; transparent conductive films are deposited on the sides of the first transparent substrate and the second transparent substrate close to each other, and the transparent conductive films can be ITO, FTO, ZTO, etc.; interface modification layers are provided on the sides of the two transparent conductive film layers close to each other; an active layer is provided between the two interface modification layers. The electrodes of the photovoltaic cell film 200 are connected with lead wires, which can lead out the current of the photoelectric effect. The lead wires are hidden in the glass ink and cannot be observed.

[0090] The anti-fog glass also includes an energy storage module and a control switch, wherein the energy storage module can be a vehicle-mounted low-voltage battery or a separate micro battery. The control switch is connected to the energy storage module signal, and the photovoltaic cell film 200 is electrically connected to the heating module through the energy storage module. The control switch is used to control the on and off of the heating module. The control switch can be set in the vehicle-mounted central control and can be controlled through the system or independently.

[0091] When the light is strong, the photovoltaic cell film 200 undergoes photoelectric conversion and collects electricity into the energy storage module. The photovoltaic cell film 200 also blocks light for the driver. When the camera area of ​​the windshield becomes foggy, the control switch of the heating module is turned on, the transmission area 150 is heated, and the evaporation of water mist on the glass surface of the transmission area 150 is accelerated, making it easier for the camera to capture images.

[0092] An embodiment of the present application further discloses a vehicle, including a camera and anti-fog glass, wherein the camera shoots the outside of the vehicle through the glass where the heating layer is located.

[0093] Specifically, the vehicle is an autonomous vehicle, and the camera shoots the outside of the vehicle through the glass where the heating layer is located, that is, the transmission area 150, to obtain road information, so that the vehicle system can process the image information transmitted by the camera through an algorithm and make the vehicle take corresponding actions. At this time, the anti-fog glass is the front windshield of the vehicle, and the transmission area 150 and the sunshade area 160 are both located near the upper part of the front windshield. There are two sunshade areas 160, and the transmission area 150 is located between the two sunshade areas 160.

[0094] After testing and verification, the temperature of the inner surface of the anti-fog glass reaches above 50°C, and the water mist in the camera area can evaporate in a short time. The photovoltaic cell film 200 can generate electricity for the heating layer 300, thereby reducing or even eliminating the power consumption of the power part in the car. The photovoltaic cell film 200 is set in the sunshade area 160 and fixed by the first film layer 120 and the second film layer 130. The photovoltaic cell film 200 has a light transmittance of 10%-50% in the visible light region, so it can block part of the light directly shining on the driver's face to prevent glare.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
