[0001] The present application relates to the technical field of laminated components, and in particular to a laminated component and a vehicle. Background Art

[0002] Electronically controlled dimming technology has been widely used in automotive glass and participates in the thermal management of the entire vehicle. However, the existing application technology still cannot achieve full blocking and transmission of visible light. Visible light will enter the car before and after dimming, bringing heat; and the light transmittance is often changed by absorbing light, which will increase the temperature of the car glass. Although the existing reflective dimming technology can realize the conversion of the device between the transparent state and the light reflection state, in the reflective state, the strong reflection of light by the device will cause light pollution, which is not conducive to the safety of driving and pedestrians.

[0003] By introducing a light diffusion layer into the reflected light path, diffuse reflection can be formed to reduce the effect of strong light pollution. However, the applicant found that in both full blocking and transmission states, the visual effects on both sides of the vehicle glass are poor due to the influence of ambient light reflection and transmission. Summary of the invention

[0004] Based on this, it is necessary to provide a stacked component and a vehicle that can improve the visual presentation effect of the stacked component.

[0017] In one embodiment, the light splitting layer comprises:

[0018] There are multiple stretched polymer film layers, and at least some of the stretched polymer film layers have different refractive indices.

[0019] In one embodiment, the stacked assembly further comprises:

[0023] The dispersion is embedded in the dispersion medium, the refractive index of the dispersion is greater than the refractive index of the dispersion medium, and the volume of the dispersion is smaller than the volume of the dispersion medium.

[0024] In one embodiment, the dispersion includes inorganic materials and organic materials; and / or the particle size distribution of the dispersion is between 1 μm and 8 μm.

[0025] In one embodiment, the particle size distribution of the dispersion is between 2 μm and 4 μm.

[0027] The above-mentioned laminated assembly and vehicle have at least the following beneficial effects:

[0028] The light modulation functional layer in the stacked component supports switching between a light transmission state and a light reflection state, and by sequentially arranging a light diffusion layer and a spectroscopic layer on the outer layer (the side close to the ambient light) of the second transparent substrate, when the light modulation functional layer is in the light reflection state, the light projected by the ambient light is reflected by the light modulation functional layer, and then diffused by the light diffusion layer to form diffuse reflection, thereby avoiding strong reflection in a certain direction. In addition, in the process of the ambient light being incident on the light modulation functional layer, the light has been split by the spectroscopic layer and diffusely reflected by the light diffusion layer. Therefore, the light reflected by the light modulation functional layer is received by the human eye through the light diffusion layer and the spectroscopic layer, and the user can observe that the stacked component presents bright colors outside the vehicle.

DETAILED DESCRIPTION

[0036] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0038] It should be understood that when a layer is referred to as being "on", it may be directly on other layers, or there may be intervening layers. Conversely, when a layer is referred to as being "directly on", there are no intervening layers. It should be understood that although the terms first, second, etc. may be used to describe various layers, these layers should not be limited by these terms. These terms are merely used to distinguish one layer from another. Thus, for example, a first transparent substrate may be referred to as a second transparent substrate, and similarly, a second transparent substrate may be referred to as a first transparent substrate; the first transparent substrate and the second transparent substrate are different transparent substrates.

[0039] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" and the like specify the presence of stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0040] As mentioned in the background technology, electronically controlled dimming technology has been widely used in the field of automotive glass to assist in the thermal management of the vehicle. However, current technology is still unable to completely block visible light and precisely control light transmittance. During the dimming process, some visible light always penetrates into the vehicle, accompanied by heat transfer. Most of these technologies rely on the principle of light absorption to adjust the transmittance of light, which still causes the temperature of the vehicle glass to rise.

[0041] Although reflective dimming technology has been introduced that can switch the device between a transparent (light-transmitting state) and a light-reflecting state, when the device is in the light-reflecting state, the strong reflected light may constitute light pollution, posing a threat to the safety of other vehicle drivers and pedestrians.

[0042] In one embodiment, the present application provides a laminated component 100 for use in a vehicle. As shown in FIG1 , the laminated component 100 includes: a first transparent substrate 1 , a light modulation functional layer 2 , a second transparent substrate 3 , a light diffusion layer 4 , and a light splitting layer 5 .

[0043] In which, from the perspective shown in FIG1 , the light modulation functional layer 2 is disposed on the first transparent substrate 1. The second transparent substrate 3 is disposed on the light modulation functional layer 2. The light diffusion layer 4 is disposed on the second transparent substrate 3. The spectroscopic layer 5 is disposed on the light diffusion layer 4. The second transparent substrate 3 is closer to the ambient light side than the first transparent substrate 1.

[0044] The light modulation functional layer is used to support light modulation, to support the transmission of ambient light and to block the transmission of ambient light. When the light modulation functional layer works in the light transmission state, it supports at least part of the ambient light to be transmitted. When the light modulation functional layer works in the light reflection state, it blocks the transmission of ambient light and reflects the ambient light.

[0045] The first transparent substrate and the second transparent substrate refer to substrates that are light-transmissive and can provide a certain support. For example, the first transparent substrate and the second transparent substrate can be, but are not limited to, a glass plate or a transparent polyimide (PI) plate or a transparent plastic plate, such as a PET (Polyethylene terephthalate) substrate.

[0046] The light diffusion layer is used to diffuse the light passing through to form diffuse reflection, which can prevent the light reflected by the light modulation functional layer from being concentrated in a certain direction when it works in the light reflection state, thereby avoiding the formation of strong light in that direction and reducing the impact on pedestrians or other drivers outside the vehicle. The light diffusion layer can also diffusely reflect the light split by the light splitting layer, providing conditions for the bright color presentation of the laminated component.

[0047] The spectroscopic layer refers to a layer that can support fine-grained adjustment of light. For example, parameters such as the divergence angle and focusing of light can be adjusted.

[0048] Specifically, the light modulation functional layer in the stacked component supports switching between a light transmission state and a light reflection state, and by sequentially arranging a light diffusion layer and a spectroscopic layer on the outer layer of the second transparent substrate (the side close to the ambient light), when the light modulation functional layer is in the light reflection state, the light projected by the ambient light is reflected by the light modulation functional layer, and then diffused by the light diffusion layer to form diffuse reflection, thereby avoiding strong reflection in a certain direction. In addition, in the process of the ambient light being incident on the light modulation functional layer, the light has been split by the spectroscopic layer and diffusely reflected by the light diffusion layer. Therefore, the light reflected by the light modulation functional layer and emitted by the light diffusion layer and the spectroscopic layer will be received by the human eye outside the vehicle, and the human eye observes that the stacked component presents a bright color.

[0049] When the light modulation functional layer is in a light transmission state, the ambient light is split by the beam splitting layer and diffusely reflected by the light diffusion layer, and part of the ambient light enters the interior of the vehicle, and is recombined with the light transmitted by the light modulation functional layer on the side of the first transparent substrate. Therefore, the user can observe that the surface of the stacked component is in visible color within a wide viewing angle inside the vehicle. Moreover, if part of the ambient light is reflected by the light modulation functional layer, as described in the previous paragraph, the stacked component observed by the user on the side where the ambient light is located presents a bright color. That is, the stacked component provided in the embodiment of the present application, by arranging a light diffusion layer and a beam splitting layer on the outer side of the second transparent substrate, can realize the controllable switching of the light modulation functional layer between the light transmission state and the light reflection state, while enabling both sides of the stacked component to present bright colors, thereby improving the visual presentation effect of the stacked component.

[0050] In one embodiment, at least one of the first transparent substrate and the second transparent substrate comprises a single-layer or multi-layer glass plate. Based on the single-layer or multi-layer glass plate, a good protective effect can be formed on the functional layer. The laminated assembly formed based on the glass plate can be widely used in transportation vehicles.

[0051] In one embodiment, as shown in FIG. Figure 3 As shown, the light modulation functional layer 2 may include a functional intermediate layer 21, a first transparent conductive layer 22 and a second transparent conductive layer 23 provided on both sides of the functional intermediate layer. The first transparent conductive layer 22 and the second transparent conductive layer 23 are connected to an external circuit, and the functional intermediate layer 21 can realize its function under the voltage drive provided by the external circuit.

[0052] The functional intermediate layer can be a single-layer structure, which can contain ion conductors, metal deposition sources, counter electrode materials, solvents and other substances, in liquid or gel state. Among them, the functional intermediate layer in gel state composed of macromolecular networks has better mechanical properties. The metal deposition source is the ion of the corresponding metal, which can form a complex ion with the counter electrode material, such as M a X b Y c-d , M is a metal element such as Ag, Cu, Au, X, Y are halogens such as Cl, Br, and a, b, c, and d correspond to different values ​​according to the different valences of the elements. When the external circuit supplies power to the first transparent conductive layer and the second transparent conductive layer, the metal will be deposited on the transparent conductive layer to form a metal layer with mirror reflection, and the entire light modulation functional layer will be in a light reflection state. After power is cut off, the metal mirror will dissolve in the functional intermediate layer, and the entire light modulation functional layer will be in a light transmission state.

[0053] like Figure 4 As shown, the functional intermediate layer 21 can also be a multilayer structure, which can include a metal deposition layer 211, an ion conductor layer 212 (which can be replaced by an ion exchange membrane + liquid electrolyte), and a counter electrode layer 213. During the charging and discharging process of the light modulation functional layer 2, the metal of the metal deposition layer 211 is deposited or dissolved, and the counter electrode layer 213 also undergoes a corresponding redox reaction. When the metal deposition layer 211 is deposited, a reflective metal mirror is formed on the second transparent conductive layer 23, and the entire light modulation functional layer 2 is in a light reflection state. When the metal deposition layer 211 is dissolved, the metal mirror will dissolve in the functional intermediate layer 21, and the entire light modulation functional layer 2 is in a light transmission state.

[0054] Optionally, the metal deposition layer may be made of a metal with strong reducing properties, such as Zn.

[0055] Optionally, the counter electrode material of the counter electrode layer has an electrochromic function. For example, a viologen material may be used for the counter electrode layer. In this case, during the metal deposition or dissolution process of the metal deposition layer, the other side of the entire light modulation functional layer changes color.

[0056] In one embodiment, the material used to prepare the functional intermediate layer may include EC (Electrochromic, electrochromic device).

[0057] In one embodiment, the first transparent conductive layer and / or the second transparent conductive layer may be made of transparent conductive oxide (TCO). Transparent conductive oxide may include but is not limited to tin-doped indium oxide (ITO), aluminum-doped zinc oxide (AZO), indium-doped cadmium oxide, etc.

[0058] In one embodiment, the first transparent conductive layer and / or the second transparent conductive layer may also be made of transparent conductive polymers such as poly(3,4-ethylenedioxythiophene) (PEDOT for short).

[0059] In one embodiment, the first transparent conductive layer and / or the second transparent conductive layer may also be a laminated film of a metal layer and a dielectric layer, silver nanowires, and a silver or copper metal mesh.

[0060] In one embodiment, the spectroscopic layer is a multi-layer structure, and the refractive index between at least some layers is different. When the spectroscopic layer is a multi-layer structure, due to the different refractive indices of different media to light, when the light passes through these medium layers, refraction and reflection will occur, so that light of a specific wavelength or light of a specific polarization direction is guided to different directions or paths, thereby achieving more precise control of the light. For example, by adjusting the structure and refractive index distribution of the spectroscopic layer, the divergence angle, focusing performance and other parameters of the light can be changed, and the reflected light can be finely adjusted in the way the user expects on the side where the ambient light outside the vehicle is located, so that the visual presentation effect of the stacked component on the ambient light side meets the user's expectations.

[0061] In one embodiment, the refractive index difference between the two layers having different refractive indices is greater than or equal to 0.1.

[0062] Among them, when the refractive index difference between two layers with different refractive indices in the spectroscopic layer is greater than or equal to 0.1, when the light passes through the interface between the two layers, obvious refraction or reflection occurs, which helps to more clearly separate light of different wavelengths or light of different polarization directions, and improves the light separation efficiency. In addition, the aliasing phenomenon of light of different wavelengths or polarizations during propagation can be reduced, so that the light can maintain better purity and directionality after passing through the spectroscopic layer. For example, yellow light is mainly reflected within a narrow viewing angle, and the remaining light is diffusely reflected by the light diffusion layer and then reflected by the light modulation layer. The human eye recognizes it as blue, so that users outside the car can observe that the surface of the stacked component is blue within a wide viewing angle on the side of the stacked component close to the ambient light. The spectroscopic layer can be designed based on the principles of being beneficial to driving and pedestrian safety and meeting the user's expected display effect.

[0063] In one embodiment, the light splitting layer may include an inorganic material layer. For example, the light splitting layer may include: a low refractive layer and a high refractive layer. It should be understood that the "high" and "low" here are relative when comparing the two.

[0064] The low refractive layer may include SiO2. The high refractive layer includes at least one of TiO2, ZnS, ZrO2, CeO2 and ZnO. SiO2 has a relatively low refractive index of about 1.46. TiO2, ZnS, ZrO2, CeO2 and ZnO have a relatively high refractive index of more than 2.0. By utilizing the significant difference in refractive index between these materials, a spectroscopic layer with a specific refractive index distribution can be designed.

[0065] By stacking the above materials with different refractive indices in a certain order and thickness, a multilayer structure can be formed, which can reflect, transmit or absorb specific wavelengths of light, thereby achieving the purpose of light splitting. It can improve the light transmittance of the vehicle-mounted laminated components, reduce reflection and glare, and improve driving safety.

[0066] Among them, SiO2, nano-scale TiO2 dispersed in transparent media or specially treated TiO2 films, high-purity ZrO2, ZnS, CeO2, and ZnO all have good transparency, which can reduce the negative impact on the user's field of vision, and take into account the lighting effect of the stacked components while achieving split light control.

[0067] In one embodiment, the light-splitting layer includes: a plurality of stretched polymer film layers, and at least some of the stretched polymer film layers have different refractive indices.

[0068] The polymer film stretching layer may be a polyester, polyacrylate, or polystyrene polymer film stretching layer.

[0069] Among them, the refractive index is an important optical parameter of the material and is closely related to factors such as the density, molecular polarity and intermolecular interaction of the material. The triazine ring can increase the rigidity of the polymer molecular chain, improve the intermolecular interaction or change the polarity of the molecule, thereby increasing the refractive index of the polymer. Aromatic ring structures, such as benzene rings, condensed rings or other aromatic ring structures, have a higher molar refractive index and can therefore effectively increase the refractive index of the polymer.

[0070] Therefore, the refractive index between the polymer film stretched layer with and without the introduction of triazine ring and aromatic ring structure is designed differently, thereby achieving the purpose of light splitting.

[0071] In one embodiment, the laminated component further comprises: a smoothing layer.

[0072] The smooth layer is arranged between the light diffusion layer and the light splitting layer, and the contact surface between the smooth layer and the light splitting layer is a smooth surface.

[0073] Specifically, by providing the smoothing layer, it is possible to prevent the protruding particles on the side of the light diffusion layer close to the ambient light from affecting the structure of the light splitting layer during the process of manufacturing the light splitting layer.

[0074] In one embodiment, the smoothing layer is a transparent material.

[0075] In one embodiment, the material of the smoothing layer has a refractive index less than or equal to that of the dispersion medium of the light diffusion layer. For example, the material of the smoothing layer can be consistent with that of the dispersion medium, or other transparent organic or inorganic materials.

[0076] In one embodiment, a flowable material may be disposed between the light diffusion layer and the beam splitting layer to form a smooth surface after solidification, or a material with bonding and filling functions may be disposed between the light diffusion layer and the beam splitting layer.

[0077] In one embodiment, the light diffusion layer includes: a dispersion medium and a dispersion.

[0078] The dispersion medium is a transparent material, the dispersed substance is embedded in the dispersion medium, the refractive index of the dispersed substance is greater than the refractive index of the dispersion medium, and the volume of the dispersed substance is smaller than the volume of the dispersion medium.

[0079] As the foundation of the light diffusion layer, the transparency of the dispersion medium is crucial. Transparent materials allow light to penetrate, allowing the light to propagate inside the medium and interact with the dispersed matter. The dispersion medium has a lower refractive index, which forms a refractive index difference with the dispersed matter, which helps the light to refract, reflect and scatter when passing through the light diffusion layer, thereby improving the uniformity and diffusion of the light projected to the human eye.

[0080] Among them, the volume of the dispersed matter is smaller than the volume of the dispersion medium, which helps the dispersed matter to be evenly distributed in the dispersion medium. At the same time, the small volume of the dispersed matter can provide more scattering points, increase the interaction opportunities between the light and the dispersed matter, and thus further improve the light diffusion effect. Therefore, through the above-mentioned differentiated design of volume and refractive index, the light diffusion layer can effectively distribute the light reflected by the light modulation functional layer evenly in all directions, thereby improving the uniformity and diffusion of the reflected light.

[0081] In one embodiment, the dispersion includes inorganic materials and organic materials; and / or the particle size distribution of the dispersion is between 1 μm and 8 μm.

[0082] The dispersed material is made of inorganic materials such as barium sulfate, calcium carbonate, and silicon dioxide. These materials are in the form of solid microspheres at the microscopic level, and light cannot completely penetrate the solid spheres. The organic materials in the dispersed material have light transmittance. The refractive index of these organic materials and inorganic material microspheres is different. After multiple light refractions, they can provide a higher light scattering intensity, change the softness of the light reflected by the light modulation functional layer, and at the same time reduce light transmission loss.

[0083] Smaller particle sizes can provide a more uniform light diffusion effect, but may increase light scattering losses; larger particle sizes may form obvious light spots or light bands. After testing, when the particle size of the dispersion is in the range of 1μm-8μm, a better light diffusion effect can be achieved while maintaining a high light transmittance.

[0084] In one embodiment, the particle size distribution of the dispersion is between 2 μm and 4 μm. When the particle size distribution of the dispersion is between 2 μm and 4 μm, compared with the particle size range of 1 μm to 8 μm, it can bring more uniform light diffusion effect, reduce light scattering loss, increase light transmittance, improve visual effect, and be easier to process and control.

[0085] In one embodiment, the dispersion medium and the second transparent substrate are made of the same material.

[0086] In order to better illustrate the implementation process of the stacked assembly provided in the embodiment of the present application, here, as shown in FIG. Figure 4 The following structure is used as an example to illustrate:

[0087] The metal deposition layer 211 is in contact with the second transparent conductive layer 23, and the counter electrode layer 213 has an electrochromic function. The light diffusion layer 4 selects transparent organic particles as the dispersed phase. In the process of charging (discharging) through the first transparent conductive layer 22 and the second transparent conductive layer 23, the metal deposition layer 211 is deposited, and the light incident on the metal deposition layer 211 is reflected by it and reflected out of the vehicle, preventing heat from entering the vehicle. The vehicle interior presents the deep color of the counter electrode layer 213 in a dark environment, and the reflected light passes through the light diffusion layer 4 and the spectroscopic layer 5, and presents a bright color after spectroscopic separation on the outside of the vehicle. In the process of discharging (charging), the metal deposition layer 211 gradually forms ions and enters the ion conductor layer 212. The ambient light that is spectroscopically separated by the spectroscopic layer 5 and diffused by the light diffusion layer 4 will partially enter the vehicle, increasing the heat in the vehicle. The vehicle interior presents the color of the light obtained by spectroscopic separation by the spectroscopic layer 5 and the electrochromic composite of the counter electrode layer 213, and the vehicle exterior presents a certain color, and the brightness is lower than the brightness when the metal deposition layer 211 is deposited. That is, while being able to realize the switching control between the light transmission and light reflection states, it is also possible to take into account the regulation of the visual presentation effect of the laminated component 100 inside and outside the vehicle to meet the user's expectations.

[0088] The laminated component provided in the embodiment of the present application can not only avoid light pollution when the reflective dimming technology is applied to the vehicle glass, but also realize the regulation of the appearance color of the vehicle glass, thereby improving the visual presentation effect of the vehicle glass and making it meet the user's expectations.

[0089] In one exemplary technology, a vehicle is provided, comprising the above-described laminated assembly.

[0090] Vehicles equipped with the above-mentioned laminated components can avoid causing light pollution to external pedestrians or drivers of other vehicles around them, affecting the travel safety of others. They can also control the appearance color of the vehicle glass, improve the visual presentation effect of the vehicle glass, and make it meet user expectations.

[0091] In one embodiment, the laminated component is vehicle glass, for example, it may include a sunroof, a windshield, side windows, etc.

[0092] In the description of this specification, the description with reference to the terms "some embodiments", "other embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic description of the above terms does not necessarily refer to the same embodiment or example.

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.

[0094] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. 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.
