TECHNICAL FIELD
[0001] The present application relates to the technical field of vehicles, in particular to a functional integrated film layer, glass and vehicle. BACKGROUND
[0002] With the increasing dependence on vehicles, vehicles are gradually developing towards intelligentization and networking, and the functional requirements of glass on vehicles, especially vehicle window glass, are increasingly diversified. The traditional vehicle window glass only serves as a basic component for light transmission and wind shielding, which cannot meet the needs of modern travel scenarios.
[0003] At present, most vehicle window glasses on the market mainly rely on the combination of multiple functional film layers or functional components to realize multiple functions of the vehicle window glass. For example, when the vehicle window glass integrates light adjustment function and heating function, the light adjustment functional film layer for realizing the light adjustment function and the heating structure for realizing the heating function need to be separately formed and each needs to use a separate substrate layer to bear, which will result in a large thickness of the vehicle window glass integrating the light adjustment functional film layer and the heating structure, thereby reducing the functional integration and overall utilization of the vehicle window glass. SUMMARY
[0004] The purpose of the present application is to provide a functional integrated film layer, glass and vehicle. The functional integrated film layer integrates light adjustment function and heating function. The glass using the functional integrated film has a smaller thickness compared with the glass using separately formed light adjustment functional film and heating structure, thereby improving the functional integration and overall utilization of the glass.
[0005] In a first aspect, an embodiment of the present application provides a functional integrated film layer. The functional integrated film layer comprises:
[0006] a light adjustment film, the light adjustment film comprising a first substrate layer and a second substrate layer, the first substrate layer and the second substrate layer being stacked along a thickness direction of the light adjustment film;
[0007] a transparent heating layer, the transparent heating layer comprising a metal mesh layer, the metal mesh layer comprising metal wires, at least part of the metal wires forming an antenna to realize an antenna function;
[0008] along the thickness direction of the functional integrated film layer, the metal mesh layer is stacked on a surface of the second substrate layer away from the first substrate layer, a projection of the metal mesh layer is completely located within a projection of the second substrate layer, or the projection of the metal mesh layer completely coincides with the projection of the second substrate layer.
[0009] In a second aspect, the embodiments of the present application provide a glass. The glass comprises an inner glass plate, two adhesive layers, an edge adhesive layer, an outer glass plate and the functional integrated film layer. The inner glass plate, one of the adhesive layers, the functional integrated film layer, the other of the adhesive layers and the outer glass plate are sequentially connected along the thickness direction of the glass. The edge adhesive layer is located between and connected to the two adhesive layers. The edge adhesive layer surrounds and is connected to the outer side of the functional integrated film layer.
[0010] In a third aspect, the embodiments of the present application further provide a vehicle. The vehicle comprises a tool body, an external power supply and the glass. The glass and the external power supply are both mounted on the tool body. The light modulation film and the transparent heating layer of the functional integrated film layer are both connected to the external power supply. The light modulation film is used for light modulation of the glass. The transparent heating layer realizes the antenna function and the heating function of the glass.
[0011] In the related art, most of the vehicle glasses on the market mainly rely on the combination of multiple functional film layers or functional components. For example, if the vehicle glass needs to have light modulation function and heating function, the light modulation functional film layer and the heating structure layer are usually separately formed and then alternately stacked with the adhesive layer. The light modulation functional film layer and the heating structure each need to use a separate substrate layer (such as a PET substrate layer) to carry. Although the vehicle glass integrates the light modulation function and the heating function, it will cause the vehicle glass to be thick and heavy, which is not conducive to the lightweight of the vehicle glass, and also reduces the functional integration and overall utilization of the vehicle glass. Moreover, the light modulation functional film layer and the heating structure need to be separately formed and then stacked with the glass plate and the adhesive layer, which increases the production process of the vehicle glass and leads to low production efficiency of the vehicle glass.
[0012] In this embodiment, a glass integrating a functional integrated film layer is provided. The functional integrated film layer includes a dimming film and a transparent heating layer. The dimming film enables dimming, and the transparent heating layer not only enables heating but can also be provided with an antenna pattern for signal transmission, thus functioning as an antenna. The functional integrated film layer also includes a protective layer. The transparent heating layer and the protective layer are directly and sequentially stacked on the base layer of the dimming film, so that the base layer of the dimming film not only supports its own conductive layer and dimming layer but also supports the transparent heating layer and the protective layer. It is understandable that, compared to the existing technology that uses separately molded dimming functional film layers and heating structures in conjunction with adhesive layers, and where dimming functional film layers and heating structures each require separate substrate layers for support, the dimming film and transparent heating layer of the functional integrated film layer in this application share a single base layer. While satisfying the integration of dimming, heating, and antenna functions of the glass, it reduces the need for an adhesive layer connecting the two functional film layers and a base layer supporting the transparent heating layer and protective layer. This not only saves on the use of adhesive materials but also improves the utilization rate of the base layer of the dimming film, reduces the overall weight and thickness of the glass, and is conducive to the lightweighting of the glass; thereby improving the functional integration and overall utilization rate of the glass.

[0031] The first bonding layer 20, the second bonding layer 30, and the edge bonding layer 40 are all located between the third surface 11 of the outer glass sheet 10 and the second surface 52 of the inner glass sheet 50. The first bonding layer 20, the second bonding layer 30, and the edge bonding layer 40 are used to bond the outer glass sheet 10 and the inner glass sheet 50 together to form a laminated glass structure, improve the structural strength of the glass 100, and avoid the glass debris from the broken outer glass sheet 10 and the inner glass sheet 50 from scratching the driver or passenger inside the vehicle 1000, so that the glass 100 meets more safety standards and regulatory requirements in more scenarios.

[0036] The functional integrated film layer 60 comprises a dimming film 61 and a transparent heating layer 62. The transparent heating layer 62 is connected to one side surface of the dimming film 61 in the thickness direction of the functional integrated film layer 60.

The transparent heating layer 62 is made of metal. Based on the electrical conductivity and electromagnetic properties of the metal, the transparent heating layer 62 can not only realize the heating function of the functional integrated film layer 60, but also realize the antenna function of the functional integrated film layer 60 by designing an antenna pattern for signal transmission. The protective layer 622 is used to protect the transparent heating layer 62.
[0037] The dimming film 61 comprises a first base layer 611, a second base layer 612 and a dimming functional layer 616 laminated.

In this embodiment, the material of the first base layer 611 can be polyethylene terephthalate (hereinafter referred to as PET). The thickness of the first base layer 611 can be greater than or equal to 125 μm and less than or equal to 255 μm. In this embodiment, the functional integrated film layer 60 is applied to the side glass 100, and the thickness of the first base layer 611 is greater than or equal to 125 μm and less than or equal to 188 μm. In some other embodiments, the functional integrated film layer 60 is applied to the glass 100, and the thickness of the first base layer 611 is greater than or equal to 188 μm and less than or equal to 255 μm.
[0039] The second base layer 612 includes a third bearing surface 6121, a fourth bearing surface 6122, and a second side surface 6123.

In the present embodiment, the functional integrated film layer 60 is applied to the side glass 100, and the thickness of the second base layer 612 is greater than or equal to 125 μm and less than or equal to 188 μm. In some other embodiments, the functional integrated film layer 60 is applied to the top glass 100, and the thickness of the second base layer 612 is greater than or equal to 188 μm and less than or equal to 255 μm.
[0040] In the present embodiment, the material of the first base layer 611 and the second base layer 612 is PET. PET has a certain hardness, which not only can bear and protect the light-adjusting functional layer 616, but also can adapt to the glass with a certain curvature. In addition, when the first base layer 611 and / or the second base layer 612 is a heat insulation layer, the first base layer 611 and / or the second base layer 612 is composed of two or more PET materials with different refractive indexes which are alternately stacked.

Along the thickness direction of the light-adjusting functional layer 616, the first conductive layer 613, the light-adjusting layer 615, and the second conductive layer 614 are sequentially stacked and connected. In the present embodiment, the first conductive layer 613 is connected to the second bearing surface 6112 of the first base layer 611. The second conductive layer 614 is connected to the third bearing surface 6121 of the second base layer 612.

In the present embodiment, the thickness of the light-adjusting functional layer 616 is greater than or equal to 5 μm and less than or equal to 30 μm.
[0042] In the present embodiment, the first side surface 6113 of the first base layer 611, the outer side surface of the first conductive layer 613, the outer side surface of the light-adjusting layer 615, the outer side surface of the second conductive layer 614, and the second side surface 6123 of the second base layer 612 are flush and collectively constitute the first side surface a of the light-adjusting film 61.
[0043] In the embodiment, the material of the first conductive layer 613 can be a metal conductor (including metal, metal oxide, etc.), or a non-metallic conductor. The metal conductor can include a transparent conductive metal oxide (TCO) and / or silver, etc. The non-metallic conductor can be a carbon material, such as a carbon nanomaterial (carbon nanotube), graphite, etc. In some specific embodiments, the material of the first conductive layer 613 specifically includes one or more than two combinations of TCO, silver, and carbon material, and the first conductive layer 613 can be a TCO layer, a nano-silver layer, a carbon layer (such as a graphite layer, a carbon nanotube layer), etc. In the above first conductive layer 613, the TCO can include one or more than two combinations of ITO (indium tin oxide), AZO (aluminum-doped tin oxide), and FTO (fluorinated tin oxide); the silver can be nano-silver, such as nano-silver wire. Therefore, the first conductive layer 613 can include one or more than two combinations of an ITO layer, an AZO layer, an FTO layer, a nano-silver layer, and a carbon layer. The first conductive layer 613 can be uniformly deposited on the second bearing surface 6112 of the first base layer 611 by sputtering, coating, etc.
[0044] In the embodiment, the material of the second conductive layer 614 can be a metal conductor (including metal, metal oxide, etc.), or a non-metallic conductor. The metal conductor can include a transparent conductive metal oxide (TCO) and / or silver, etc. The non-metallic conductor can be a carbon material, such as a carbon nanomaterial (carbon nanotube), graphite, etc. In some specific embodiments, the material of the second conductive layer 614 specifically includes one or more than two combinations of TCO, silver, and carbon material, and the second conductive layer 614 can be a TCO layer, a nano-silver layer, a carbon layer (such as a graphite layer, a carbon nanotube layer), etc. In the above second conductive layer 614, the TCO can include one or more than two combinations of ITO (indium tin oxide), AZO (aluminum-doped tin oxide), and FTO (fluorinated tin oxide); the silver can be nano-silver, such as nano-silver wire. Therefore, the second conductive layer 614 can include one or more than two combinations of an ITO layer, an AZO layer, an FTO layer, a nano-silver layer, and a carbon layer. The second conductive layer 614 can be uniformly deposited on the third bearing surface 6121 of the second base layer 612 by sputtering, coating, etc.
[0045] In this embodiment, the material of the light-adjusting layer 615 can include, but is not limited to, one or more than two combinations of dye liquid crystal (LC), polymer dispersed liquid crystal (PDLC), guest-host liquid crystal (GHLC), polymer network liquid crystal (PNLC), polymer stabilized liquid crystal (PSLC), pixel isolated liquid crystal (PILC), electrochromic device (EC), and suspended particle device (SPD). The light-adjusting layer 615 can be uniformly attached to the surface of the first conductive layer 613 away from the first base layer 611 or the surface of the second conductive layer 614 away from the second base layer 612 by sputtering, coating, or other process methods. The first conductive layer 613 and the second conductive layer 614 are uniformly deposited, and the first conductive layer 613 and the second conductive layer 614 are respectively located on opposite sides of the thickness direction of the light-adjusting layer 615. When the external power supply is powered on to the first conductive layer 613 and the second conductive layer 614, a uniform electric field can be formed between the first conductive layer 613 and the second conductive layer 614. The uniform electric field can drive the liquid crystal molecules in the light-adjusting layer 615 to arrange in order along the direction of the electric field, avoiding local light-adjusting unevenness of the light-adjusting film 61. Moreover, the light-adjusting layer 615 is in a transparent state after being powered on, and has a high visible light transmittance, which can ensure the brightness of the internal environment of the vehicle 1000, and is conducive to observing the external and internal environment of the vehicle 1000 through the glass 100. When the external power supply is powered off to the first conductive layer 613 and the second conductive layer 614, the liquid crystal molecules in the light-adjusting layer 615 restore random and disordered distribution, the light-adjusting layer 615 is in an opaque or fogging state, and has a low visible light transmittance and a high haze, so as to play a role of sunshade and privacy protection. It can be understood that the visible light transmittance of the light-adjusting film 61 can be adjusted by the external power supply to meet the visible light transmittance and haze requirements of the glass 100 in multiple scenarios.
[0046] In some embodiments, the light-adjusting film 61 can be replaced by other functional film layers with a PET base layer to realize other functions of the functional integrated film layer 60. The present application does not limit this.
[0047] The transparent heating layer 62 comprises a first surface 6211 and a second surface 6212. The first surface 6211 and the second surface 6212 are oppositely arranged along the thickness direction of the transparent heating layer 62. The material of the transparent heating layer 62 can be at least one of a metal mesh, a metal nanowire or a carbon nanotube. In this embodiment, the material of the transparent heating layer 62 is the metal mesh, and the metal mesh is a mesh structure formed by arranging metal wires in a disordered mesh shape. The metal wires are metal materials. The diameter of the metal wires can be greater than or equal to 3 μm and less than or equal to 15 μm. That is, the thickness of the transparent heating layer 62 is greater than or equal to 3 μm and less than or equal to 15 μm. Preferably, the diameter of the metal wires can be greater than or equal to 5 μm and less than or equal to 10 μm. That is, the thickness of the transparent heating layer 62 is greater than or equal to 5 μm and less than or equal to 10 μm. The diameter of the metal wires not only meets the heating power, but also the appearance of the metal wires is invisible, avoiding the influence of the metal wires on the appearance of the glass 100 and the line of sight of people, thereby avoiding inconvenience to the use of the vehicle 1000. In addition, without affecting the heating of the transparent heating layer 62, an antenna pattern for signal transmission is arranged on the transparent heating layer 62, that is, simulation verification can be performed according to the requirements of the antenna, and the antenna pattern is formed on the transparent heating layer 62. The antenna pattern of the transparent heating layer 62 is not limited in this application.
[0048] In some embodiments, the transparent heating layer 62 is the metal nanowire, which can be defined as a one-dimensional structure with a lateral size of less than 100 nm (without limitation in the longitudinal direction). According to different materials, the material of the metal nanowire can be, but is not limited to, silver, nickel, platinum, gold, etc. In addition to the excellent electrical conductivity of silver, the metal nanowire made of silver also has excellent light transmission and bending resistance due to the size effect at the nanometer level.
[0049] The protective layer 622 comprises a first connecting surface 6221 and a second connecting surface 6222. The first connecting surface 6221 and the second connecting surface 6222 are oppositely arranged along the thickness direction of the protective layer 622. In this embodiment, the protective layer 622 is an inert metal material, such as silver (Ag), gold (Au) and the like. The protective layer 622 has good stability and oxidation resistance. Moreover, the protective layer 622 also meets the demand of visible light transmission.
[0050] The first connecting surface 6221 of the protective layer 622 is connected with the second surface 6212 of the transparent heating layer 62. In the thickness direction of the transparent heating layer 62, the projection of the transparent heating layer 62 is completely located in the projection of the protective layer 622, or the projection of the transparent heating layer 62 completely coincides with the projection of the protective layer 622. In this embodiment, the projection of the transparent heating layer 62 completely coincides with the projection of the protective layer 622, that is, the outer side surface of the protective layer 622 and the outer side surface of the transparent heating layer 62 are flush, so as to sufficiently protect the transparent heating layer 62. The outer side surface of the protective layer 622 and the outer side surface of the transparent heating layer 62 together constitute the second side surface b of the transparent heating layer 62.
[0051] The transparent heating layer 62 further comprises two connecting electrodes (not shown in the figure). The two connecting electrodes are arranged on the two sides of the transparent heating layer 62 respectively and are connected with the transparent heating layer 62. The two connecting electrodes are both used to be electrically connected with an external power supply and the transparent heating layer 62. When the external power supply supplies electricity to the two connecting electrodes, the current flows into one connecting electrode, flows through the transparent heating layer 62 and then flows out of the other connecting electrode. The metal wire has resistance, and the current passing through the metal wire generates heat, so as to realize the heating function of the transparent heating layer 62. It should be noted that the two connecting electrodes can be arranged and designed in structure according to actual product application. The present application does not limit this.
[0052] After the light-adjusting film 61 is formed, the transparent heating layer 62 and the protective layer 622 are stacked on the second base layer 612 of the light-adjusting film 61 in sequence. Specifically, first, the heating base layer is plated on the fourth bearing surface 6122 of the second base layer 612. The heating base layer is etched by laser process and forms the transparent heating layer 62 with an antenna pattern. The first surface 6211 of the transparent heating layer 62 is connected to the fourth bearing surface 6122 of the second base layer 612. The second surface 6212 of the transparent heating layer 62 faces away from the second base layer 612. On the side of the second surface 6212 of the transparent heating layer 62, the protective layer 622 is plated to protect the transparent heating layer 62, so as to ensure that the transparent heating layer 62 is not oxidized and discolored, and also ensure that the transparent heating layer 62 is not oxidized and loses the electric conductivity.
[0053] The first side surface a of the dimming film 61 and the second side surface b of the transparent heating layer 62 together constitute the outer surface of the functional integrated film layer 60. Along the thickness direction of the functional integrated film layer 60, the projection of the transparent heating layer 62 lies entirely within the projection of the second base layer 612, or the projection of the transparent heating layer 62 completely coincides with the projection of the second base layer 612. In this embodiment, along the thickness direction of the functional integrated film layer 60, the projection of the transparent heating layer 62 completely coincides with the projection of the second base layer 612. That is, the second side surface b of the transparent heating layer 62 is flush with the second side surface 6123 of the second base layer 612. In other words, the second side surface b of the transparent heating layer 62 is flush with the first side surface a of the dimming film 61. The distance between the second side surface b of the transparent heating layer 62 and the second side surface 6123 of the second base layer 612 is L1. L1 equals 0 mm.
[0054] like Figure 2 and Figure 3 As shown, the inner glass plate 50, the first adhesive layer 20, the functional integrated film layer 60, the second adhesive layer 30, and the outer glass plate 10 are sequentially stacked along the thickness direction of the glass 100. The edge adhesive layer 40 is located between the first adhesive layer 20 and the second adhesive layer 30 and is connected to the first adhesive layer 20 and the second adhesive layer 30. The edge adhesive layer 40 surrounds and connects to the outer side of the functional integrated film layer 60.
[0055] Specifically, the first adhesive surface 21 of the first adhesive layer 20 is connected to the second surface 52 of the inner glass plate 50. The fourth adhesive surface 32 of the second adhesive layer 30 is connected to the third surface 11 of the outer glass plate 10. The fifth adhesive surface 41 of the edge adhesive layer 40 is connected to the second adhesive surface 22 of the first adhesive layer 20. The sixth adhesive surface 42 of the edge adhesive layer 40 is connected to the third adhesive surface 31 of the second adhesive layer 30. The outer surface of the inner glass plate 50, the outer surface of the first adhesive layer 20, the outer surface of the second adhesive layer 30, the outer surface of the outer glass plate 10, and the outer surface of the edge adhesive layer 40 together constitute the outer surface of the glass 100.
[0056] The functional integrated film layer 60 is housed within the mounting groove 43 of the edge adhesive layer 40.
[0057] Specifically, the two surfaces of the functional integrated film layer 60 in the thickness direction are exposed through the mounting groove 43. In one embodiment, the two surfaces of the functional integrated film layer 60 in the thickness direction are flush with the fifth bonding surface 41 and the sixth bonding surface 42 of the edge bonding layer 40, respectively, to ensure that there is no thickness difference between the functional integrated film layer 60 and the edge bonding layer 40, and to avoid uneven thickness of the glass 100 after lamination.
[0058] The second side 6123 of the second base layer 612 (also referred to as the outer side of the functional integrated film layer 60 in this embodiment) is connected to the groove wall surface 44 of the mounting groove 43. In the thickness direction of the glass 100, the distance between the second side 6123 of the second base layer 612 and the outer side of the edge bonding layer 40 is L2, which can be greater than or equal to 10 mm and less than or equal to 20 mm, so as to avoid air or water vapor from easily entering the gap between the edge bonding layer 40 and the first bonding layer 20 or the gap between the edge bonding layer 40 and the second bonding layer 30 and contacting the functional integrated film layer 60, thereby ensuring the electrical conductivity stability of the functional integrated film layer 60 and prolonging the service life of the functional integrated film layer 60. Preferably, the distance L2 between the second side 6123 of the second base layer 612 and the outer side of the edge bonding layer 40 is 10 mm. In an embodiment, the outer side of the inner glass plate 50, the outer side of the first bonding layer 20, the outer side of the second bonding layer 30, the outer side of the outer glass plate 10, and the outer side of the edge bonding layer 40 are flush, and the distance L2 between the second side 6123 of the second base layer 612 and the outer side of the edge bonding layer 40 can be regarded as the distance between the second side 6123 of the second base layer 612 and the outer side of the glass 100.
[0059] In the thickness direction of the glass 100, the transparent heating layer 62 of the functional integrated film layer 60 is closer to the outer glass plate 10 than the dimming film 61. The first bearing surface 6111 of the first base layer 611 is connected to the second bonding surface 22 of the first bonding layer 20. The second connecting surface 6222 of the protective layer 622 is connected to the third bonding surface 31 of the second bonding layer 30. In some embodiments, the transparent heating layer 62 and the protective layer 622 can be sequentially stacked on the first base layer 611 of the dimming film 61, and the first surface 6211 of the transparent heating layer 62 is connected to the first bearing surface 6111 of the first base layer 611. The fourth bearing surface 6122 of the second base layer 612 is connected to the second bonding surface 22 of the first bonding layer 20.
[0060] The glass 100 is mounted on the tool body 300, and the first conductive layer 613 and the second conductive layer 614 of the dimming film 61 and the transparent heating layer 62 of the transparent heating layer 62 are electrically connected to an external power source. The external power source is powered on or off to the first conductive layer 613 and the second conductive layer 614 to achieve the dimming function. The external power source is powered on to the two connecting electrodes, and a certain resistance is formed between the two connecting electrodes and the metal wires of the transparent heating layer 62. By applying a potential difference to the two connecting electrodes, the metal wires in the transparent heating layer 62 connected to the two connecting electrodes generate heat, thereby achieving the heating function to remove frost, snow, water mist, etc. on the surface of the glass 100. In addition, the metal wires have electromagnetic properties and are invisible in appearance, and can receive or shield electromagnetic waves, not only achieving the antenna function, but also ensuring that the antenna is invisible in appearance.
[0061] In this embodiment, the first bonding layer 20 can be PVB or EVA. The second bonding layer 30 is EVA. When the transparent heating layer 62 of the function integrated film layer 60 is turned on, the second bonding layer 30 will not produce molecules (such as CO, H2, H2, etc.) that can be oxidized and reduced with the metal mesh of the transparent heating layer 62 even if it is decomposed or degraded under heat. Moreover, the molecules produced by the decomposition of the second bonding layer 30 are stable in performance and will not be ionized with the metal mesh of the transparent heating layer 62, avoiding the problem of poor heating of the metal mesh due to ion migration; further ensuring the heating function and antenna function of the function integrated film layer 60. In one embodiment, the first bonding layer 20 can be PVB. The second bonding layer 30 is EVA. By applying a direct current voltage of 12V to the transparent heating layer 62 of the glass 100 of this embodiment and continuously energizing the transparent heating layer 62, while the transparent heating layer 62 ensures that the heating temperature is greater than or equal to 45℃ and less than or equal to 55℃, after more than 1000 hours, the appearance of the transparent heating layer 62 is stable and no discoloration or other appearance problems occur. It can be understood that the transparent heating layer 62 of the glass 100 of this embodiment is stable in appearance performance after experimental verification, and will not have discoloration or other appearance problems after long-term use.
[0062] In one embodiment, the first bonding layer 20 can be EVA. The second bonding layer 30 is EVA. By applying a direct current voltage of 12V to the transparent heating layer 62 of the glass 100 of this embodiment and continuously energizing the transparent heating layer 62, while the transparent heating layer 62 ensures that the heating temperature is greater than or equal to 45℃ and less than or equal to 55℃, after more than 1000 hours, the appearance of the transparent heating layer 62 is stable and no discoloration or other appearance problems occur. Further, the glass 100 in this embodiment is placed in an environment with a temperature of 90℃, and after 1000 hours, the appearance of the transparent heating layer 62 is still stable and no discoloration or other appearance problems occur. It can be understood that the transparent heating layer 62 of the glass 100 of this embodiment is stable in appearance performance after experimental verification, and will not have discoloration or other appearance problems after long-term use in a high temperature environment.
[0063] In the related art, most of the vehicle glasses on the market mainly rely on a combination of multiple functional film layers or functional components. For example, if a vehicle glass is to have a light adjusting function and a heating function, the light adjusting function film layer and the heating structure layer are usually separately formed and then alternately stacked with the adhesive layer, and the light adjusting function film layer and the heating structure each need to use a separate substrate layer (such as a PET substrate layer) to carry. Although the vehicle glass integrates the light adjusting function and the heating function, it causes the vehicle glass to be thick and heavy, which is not conducive to the lightweight of the vehicle glass, and also reduces the functional integration and overall utilization of the vehicle glass. Moreover, the light adjusting function film layer and the heating structure need to be separately formed and then stacked with the glass plate and the adhesive layer, which increases the production process of the vehicle glass and reduces the production efficiency of the vehicle glass.
[0064] As shown in Figure 2 and Figure 3 In the embodiments of the present application, a glass 100 integrated with a functional integrated film layer 60 is provided, the functional integrated film layer 60 including a light adjusting film 61 and a transparent heating layer 62. The light adjusting film 61 can realize the light adjusting function, and the transparent heating layer 62 can not only realize the heating function, but also can be provided with an antenna pattern for signal transmission to realize the antenna function. The functional integrated film layer 60 further includes a protective layer 622. The transparent heating layer 62 and the protective layer 622 are directly stacked in sequence on the substrate layer of the light adjusting film 61, so that the substrate layer of the light adjusting film 61 is not only used to carry the conductive layer and the light adjusting layer 615 of itself, but also used to carry the transparent heating layer 62 and the protective layer 622. It can be understood that, compared with the prior art in which the light adjusting function film layer and the heating structure are separately formed and matched with the adhesive layer, and the light adjusting function film layer and the heating structure each need to use a separate substrate layer to carry, the light adjusting film 61 and the transparent heating layer 62 of the functional integrated film layer 60 of the present application share one substrate layer, which not only meets the integration of the light adjusting function, the heating function and the antenna function of the glass 100, but also reduces one adhesive layer for connecting the two functional film layers and one PET substrate layer for carrying the transparent heating layer 62 and the protective layer 622. This not only saves the use of adhesive material, but also improves the utilization rate of the substrate layer of the light adjusting film 61, reduces the overall weight and thickness of the glass 100, and is conducive to the lightweight of the glass 100; and further improves the functional integration and overall utilization of the glass 100.
[0065] Compared with the prior art in which the light adjusting function film layer and the heating structure need to be separately formed and assembled, the light adjusting film 61 and the transparent heating layer 62 in the present application are formed together into the functional integrated film layer 60, and the transparent heating layer 62 and the protective layer 622 of the transparent heating layer 62 are directly formed on the substrate layer of the light adjusting film 61, which simplifies the production process of the glass 100 and improves the production efficiency of the glass 100.

[0067] In the present embodiment, the second side surface b of the transparent heating layer 62 of the functional integrated film layer 60 is inwardly recessed towards the middle of the functional integrated film layer 60 compared to the second side surface 6123 of the second base layer 612 of the light control film 61, which is different from the structure of the glass 100 in the first embodiment. That is, along the thickness direction of the functional integrated film layer 60, the projection of the transparent heating layer 62 is completely located within the projection of the second base layer 612, and the distance from the second side surface b of the transparent heating layer 62 to the outer side surface of the edge bonding layer 40 is greater than the distance from the second side surface 6123 of the second base layer 612 to the outer side surface of the edge bonding layer 40.

The distance L1 from the second side surface b of the transparent heating layer 62 to the second side surface 6123 of the second base layer 612 can be greater than 0 mm and less than or equal to 5 mm. Preferably, the distance L1 from the second side surface b of the transparent heating layer 62 to the second side surface 6123 of the second base layer 612 is greater than or equal to 1 mm and less than or equal to 3 mm.

[0068] In the present embodiment, the second side surface b of the transparent heating layer 62 of the functional integrated film layer 60 is inwardly recessed towards the middle of the functional integrated film layer 60 compared to the second side surface 6123 of the second base layer 612, which is different from the structure of the glass 100 in the first embodiment.

That is, the second side surface b of the transparent heating layer 62 is distanced from the second side surface 6123 of the second base layer 612. The distance L1 from the second side surface b of the transparent heating layer 62 to the second side surface 6123 of the second base layer 612 can be greater than 0 mm and less than or equal to 5 mm.

[0069] In the embodiment, the first adhesive layer 20 can be PVB or EVA. The second adhesive layer 30 is EVA. In one embodiment, the first adhesive layer 20 can be PVB. The second adhesive layer 30 is EVA. By applying a direct current 12V voltage to the transparent heating layer 62 of the glass 100 of the embodiment, and continuously energizing the transparent heating layer 62, while the transparent heating layer 62 ensures that the heating temperature is greater than or equal to 45℃ and less than or equal to 55℃, after more than 1000 hours, the appearance of the transparent heating layer 62 is stable, and there is no appearance problem such as discoloration. It can be understood that the transparent heating layer 62 of the glass 100 of the embodiment is experimentally verified, and the appearance performance is stable, and there is no appearance problem such as discoloration after long-term use.

[0071] It should be noted that the same content in the embodiment as in the above first embodiment is not repeated here.
[0072] Please refer to Figure 5 , Figure 5 for Figure 1 the third embodiment of the cross-sectional structure diagram of the partial structure of the glass of the vehicle.
[0073] In the embodiment, the structure of the glass 100 in the above first embodiment is different. In the embodiment, the functional integrated film layer 60 is inverted, and the dimming film 61 is closer to the outer glass plate 10 than the transparent heating layer 62 in the thickness direction of the glass 100. The transparent heating layer 62 is connected to the first adhesive layer 20, and the dimming film 61 is connected to the second adhesive layer 30. That is, the second base layer 612 of the dimming film 61 faces the inner glass plate 50, and the first base layer 611 faces the outer glass plate 10.
[0074] Specifically, the second connecting surface 6222 of the protective layer 622 of the transparent heating layer 62 is connected to the second adhesive surface 22 of the first adhesive layer 20. The first bearing surface 6111 of the first base layer 611 of the dimming film 61 is connected to the third adhesive surface 31 of the second adhesive layer 30. In some embodiments, the transparent heating layer 62 is laminated on the first base layer 611 of the dimming film 61, and the fourth bearing surface 6122 of the second base layer 612 of the dimming film 61 is connected to the third adhesive surface 31 of the second adhesive layer 30. Further, the second side surface b of the transparent heating layer 62 may also be recessed inward relative to the first side surface 6113 of the first base layer 611 of the dimming film 61 towards the center of the functionally integrated film layer 60. This application does not limit this.
[0075] It should be noted that the contents that are the same as those in the first embodiment described above will not be repeated here.
[0076] Please see Figure 6 , Figure 6 for Figure 1 A cross-sectional schematic diagram of a fourth embodiment of the glass portion structure of the vehicle shown.
[0077] In this embodiment, unlike the structure of the glass 100 in the first embodiment described above, the functional integrated film layer 60 of the glass 100 further includes an additional functional layer 63. Along the thickness direction of the glass 100, the additional functional layer 63 is located between the first adhesive layer 20 and the dimming film 61, and is laminated and connected to the first adhesive layer 20 and the dimming film 61. In some embodiments, the additional functional layer 63 may also be laminated and connected to the side surface of the transparent heating layer 62 facing away from the dimming film 61.
[0078] The additional functional layer 63 includes a third surface 631, a fourth surface 632, and a third side surface c. The third surface 631 and the fourth surface 632 are disposed opposite to each other along the thickness direction of the additional functional layer 63. The third side surface c is connected to the third surface 631 and the fourth surface 632.
[0079] The additional functional layer 63 is laminated on the side surface of the light control film 61 away from the transparent heating layer 62, and is accommodated in the mounting through slot 43 of the edge bonding layer 40 together with the light control film 61 and the transparent heating layer 62. Specifically, the fourth surface 632 of the additional functional layer 63 is connected to the first bearing surface 6111 of the first base layer 611. The third surface 631 of the additional functional layer 63 is connected to the second bonding surface 22 of the first bonding layer 20. The third side surface c of the additional functional layer 63 is connected to the slot wall surface 44 of the mounting through slot 43. The third side surface c of the additional functional layer 63, the first side surface a of the light control film 61, and the second side surface b of the transparent heating layer 62 together form the outer side surface of the functional integrated film layer 60. The projection of the additional functional layer 63 along the thickness direction of the glass 100 coincides or substantially coincides with the projection of the first base layer 611. In some embodiments, the additional functional layer 63 can also be embedded in the first bonding layer 20 or the second bonding layer 30.
[0080] The additional functional layer 63 can have at least one of a heat insulation, ultraviolet insulation, sound insulation, and the like. In this embodiment, the additional functional layer 63 is a heat insulation layer, which can enable the glass 100 to have a heat insulation function, thereby improving the comfort of the interior of the vehicle 1000. The material of the additional functional layer 63 can be selected from a single silver nano coating, a double silver nano coating, a triple silver nano coating, a quadruple silver nano coating, an ITO nano coating, an FTO nano coating, an infrared blocking micron coating, and the like.
[0081] In the related art, a heat insulation material can need to be arranged on the surface of the PET base layer to form an additional functional layer to realize the function of heat insulation. If the vehicle window glass needs to integrate the functions of heat insulation, light control, and heating, it is usually through the alternative laminating arrangement of the additional functional layer, the light control film layer, and the metal heating film layer with the bonding layer, although the vehicle window glass integrates multiple functions, such a simple superposition not only increases the thickness and weight of the vehicle window glass, which is not conducive to the lightweight of the vehicle window glass, but also leads to low functional integration and overall utilization of the vehicle window glass.
[0082] In the embodiments of the present application, the functional integrated film layer 60 includes not only the light control film 61 and the transparent heating layer 62, but also the additional functional layer 63. The additional functional layer 63 is directly formed on the first base layer 611 of the light control film 61. Compared with the prior art in which the additional functional layer needs a PET base layer as a bearing layer, the additional functional layer 63 of the present application is directly compounded on the first bearing surface 6111 of the first base layer 611, not only satisfying the integration of the light control function, the heating function, the antenna function, and the heat insulation function of the functional integrated film layer 60, but also further improving the utilization of the two base layers of the light control film 61, reducing the weight and thickness of the glass 100, and being conducive to the lightweight of the glass 100; and further improving the functional integration and overall utilization of the glass 100.
[0083] Moreover, compared with the prior art, the additional functional layer 63 is directly formed on the dimming film 61, which simplifies the production process of the glass 100 and improves the production efficiency of the glass 100.
[0084] It can be understood that, in the embodiments of the present application, the dimming film 61, the transparent heating layer 62 and the additional functional layer 63 are integrated, the transparent heating layer 62 and the dimming film 61 share one base layer, and the additional functional layer 63 and the dimming film 61 share one base layer, which reduces the adhesive layers for connecting the dimming film 61 and the transparent heating layer 62 and for connecting the dimming film 61 and the additional functional layer 63, reduces the use of two PET base layers, saves the manufacturing materials of the glass 100, reduces the thickness and weight of the glass 100, is conducive to the lightweight of the glass 100, and further simplifies the production process of the glass 100 and improves the production efficiency of the glass 100.
[0085] It should be noted that the same content in the embodiments as in the first embodiment is not repeated here.
[0086] The embodiments of the present application are described in detail above, and the specific examples are applied to the principles and implementation modes of the present application. The above embodiment is only used to help understand the method and core idea of the present application; meanwhile, for those skilled in the art, the specific implementation mode and application range will be changed according to the idea of the present application, and the above description should not be understood as the limitation of the present application.
