Description

Technical Field

[0001] This application relates to the field of dimming technology, and in particular to a composite dimming component, composite dimming glass, and vehicle. Background Technology

[0002] With the development of dimming technology, dimming products are becoming increasingly diversified, and users' demands for personalized dimming products are also growing. As user needs become more diverse, single-structure dimming products can no longer meet these needs. Therefore, composite dimming products that combine dimming and ambient lighting functions have emerged. Traditional technology achieves ambient lighting effects by adding an independent layer to an existing single-structure dimming product. However, this layering method can lead to insufficient positional matching between the ambient lighting layer and the dimming film layer, resulting in pattern misalignment. Utility Model Content

[0003] Therefore, it is necessary to provide a composite dimming component, composite dimming glass, and vehicle that can improve the positional matching degree between the ambient light layer and the dimming film layer, in order to address the above-mentioned technical problems.

[0004] In a first aspect, this application proposes a composite dimming component, comprising: a first substrate layer, a dimming functional layer, a second substrate layer, and a light-emitting functional layer stacked sequentially, wherein the light-emitting functional layer comprises a first conductive layer and a light-emitting element layer stacked, one side of the first conductive layer is connected to the second substrate layer, and the other side of the first conductive layer is electrically connected to the light-emitting element layer.

[0005] In one embodiment, the dimming functional layer includes a second conductive layer, a dimming element layer and a third conductive layer stacked sequentially, wherein the second conductive layer is connected to the first substrate layer and the third conductive layer is connected to the second substrate layer.

[0006] In one embodiment, the composite dimming component further includes: a first protective layer and a second protective layer, wherein the first protective layer covers the first substrate layer and the second protective layer covers the light-emitting element layer.

[0007] In one embodiment, the composite dimming component further includes: a first connecting layer, one side of which is electrically connected to the first conductive layer, and the other side of which is electrically connected to the first flexible circuit board.

[0008] In one embodiment, the composite dimming component further includes: a second connecting layer and a third connecting layer, wherein one side of the second connecting layer is electrically connected to the second conductive layer, and the other side of the second connecting layer is electrically connected to the second flexible circuit board; one side of the third connecting layer is electrically connected to the third conductive layer, and the other side of the third connecting layer is electrically connected to the third flexible circuit board.

[0009] In one embodiment, the light-emitting element layer includes a plurality of LED beads.

[0010] In one embodiment, the dimming element layer is one of a white polymer-dispersed liquid crystal film, a dye polymer-dispersed liquid crystal film, a suspended particle film, a dye liquid crystal film, and an electrochromic film.

[0011] Secondly, this application also proposes a composite dimming glass, comprising: a first glass layer, a first adhesive layer, a second glass layer, a second adhesive layer, and the composite dimming component described in the first aspect embodiment above, wherein the first glass layer is bonded to the first substrate layer of the composite dimming component through the first adhesive layer, and the second glass layer is bonded to the light-emitting element layer of the composite dimming component through the second adhesive layer.

[0012] In one embodiment, the first adhesive layer and the second adhesive layer are one of polyvinyl butyral, polyethylene-polyvinyl acetate copolymer, and ethylene-methacrylic acid copolymer.

[0013] Thirdly, this application also proposes a vehicle comprising: the composite dimming glass described in the second aspect embodiment above.

[0014] The aforementioned composite dimming component, composite dimming glass, and vehicle are constructed by sequentially stacking a first substrate layer, a dimming functional layer, a second substrate layer, and a light-emitting functional layer. Since both the dimming functional layer and the light-emitting functional layer are connected to the second substrate layer, they can be aligned with the second substrate layer as a reference during the manufacturing process. This improves the positional matching between the dimming functional layer and the light-emitting functional layer and prevents the pattern formed by the dimming functional layer or the light-emitting functional layer from shifting.

Detailed Implementation

[0026] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0027] In one embodiment, such as Figure 1As shown, this application proposes a composite dimming component, including: a first substrate layer 110, a dimming functional layer 120, a second substrate layer 130 and a light-emitting functional layer 140 stacked sequentially, wherein the light-emitting functional layer 140 includes a first conductive layer 141 and a light-emitting element layer 142 stacked together, one side of the first conductive layer 141 is connected to the second substrate layer 130, and the other side of the first conductive layer 141 is electrically connected to the light-emitting element layer 142.

[0028] Specifically, the composite dimming component of this application has dimming and ambient lighting functions. The dimming function is implemented by the dimming function layer 120, and the ambient lighting function is implemented by the light-emitting function layer 140. The dimming area on the dimming function layer 120 can be a regular shape (such as a rectangle, circle, triangle, etc.) or an irregular pattern, and the light-emitting area on the light-emitting function layer 140 can also form a regular shape (such as a rectangle, circle, triangle, etc.) or an irregular pattern, which can be set according to specific usage needs.

[0029] The first substrate layer 110 provides structural support for the entire composite dimming assembly, ensuring its stability and reliability. Simultaneously, the first substrate layer 110 also provides isolation and protection, isolating the dimming functional layer 120 from the external environment and preventing damage from external factors (such as moisture, dust, mechanical damage, etc.). The first substrate layer 110 is typically made of materials with good mechanical properties and thermal stability, such as polyimide (PI), polyester (PET), or other polymer materials. In some embodiments, the first substrate layer 110 may also possess certain optical properties, such as light transmittance and reflectivity, to optimize the overall optical performance of the composite dimming assembly.

[0030] A dimming functional layer 120 is disposed on one side of the first substrate layer 110 and is used to adjust its light transmittance or color according to external control signals (such as voltage, current, light signals, etc.). When the dimming functional layer 120 can be dimmed by light signals, it can be made of photochromic materials (such as azobenzene polymers, spiropyran copolymers, diarylethylene polymers, etc.). When the dimming functional layer 120 can be dimmed by electrical signals, it can be made of electrochromic materials (such as white polymer-dispersed liquid crystal materials, dye polymer-dispersed liquid crystal materials, suspended particle materials, dye liquid crystal materials, etc.).

[0031] Similar to the first substrate layer 110, the second substrate layer 130 also provides structural support for the entire composite dimming assembly. The second substrate layer 130 is disposed on the side of the dimming functional layer 120 that does not contact the first substrate layer 110, i.e., the dimming functional layer 120 is located between the first substrate layer 110 and the second substrate layer 130. Simultaneously, the second substrate layer 130 also serves to isolate the dimming functional layer 120 and the light-emitting functional layer 140 to prevent mutual interference between them. The second substrate layer 130 is typically made of a material with good mechanical properties and thermal stability, such as polyimide (PI), polyester (PET), or other polymer materials. In some embodiments, the second substrate layer 130 may also possess certain optical properties, such as light transmittance and reflectivity, to optimize the overall optical performance of the composite dimming assembly.

[0032] The light-emitting functional layer 140 is used to realize the ambient lighting function, and it includes a first conductive layer 141 and a light-emitting element layer 142 stacked together. A second substrate layer 130 is connected to one side of the first conductive layer 141, serving to support and form the first conductive layer 141. The other side of the first conductive layer 141 is electrically connected to the light-emitting element layer 142, providing a stable current path for the light-emitting element layer 142 and ensuring the normal operation of the light-emitting element. The first conductive layer 141 is typically made of a material with good conductivity, such as a metal thin film, metal mesh, indium tin oxide (ITO), nano-silver, or conductive polymer materials. The light-emitting element layer 142 typically includes multiple light-emitting elements, such as LED (Light-Emitting Diode) beads or OLED (Organic Light-Emitting Diode) devices. The light-emitting elements can be disposed on the first conductive layer 141 by welding, bonding, or other connection methods, and electrically connected to the first conductive layer 141, thereby realizing the ambient lighting function. It is understood that the light-emitting element layer 142 can emit only monochromatic light, or it can have a color adjustment function to emit different colors of light.

[0033] The aforementioned composite dimming component is constructed by sequentially stacking a first substrate layer 110, a dimming functional layer 120, a second substrate layer 130, and a light-emitting functional layer 140. Since both the dimming functional layer 120 and the light-emitting functional layer 140 are connected to the second substrate layer 130, during the manufacturing process, the dimming functional layer 120 and the light-emitting functional layer 140 can be aligned with the second substrate layer 130 as a reference, thereby improving the positional matching degree between the dimming functional layer 120 and the light-emitting functional layer 140 and preventing the pattern position formed by the dimming functional layer 120 or the light-emitting functional layer 140 from shifting.

[0034] In one embodiment, such as Figure 2As shown, the dimming function layer 120 includes a second conductive layer 121, a dimming element layer 122 and a third conductive layer 123 stacked in sequence. The second conductive layer 121 is connected to the first substrate layer 110 and the third conductive layer 123 is connected to the second substrate layer 130.

[0035] Specifically, in this embodiment, the dimming functional layer 120 is a film layer with electrochromic function. The dimming element layer 122 is disposed between the second conductive layer 121 and the third conductive layer 123, with the second conductive layer 121 connected to the first substrate layer 110 and the third conductive layer 123 connected to the second substrate layer 130. The second conductive layer 121 and the third conductive layer 123 provide a current path to the dimming element layer 122. When an electrical signal is applied to the dimming element layer 122, the dimming element layer 122 changes its transmittance, thereby completing dimming. In some embodiments, the dimming element layer 122 is one of a white polymer-dispersed liquid crystal film (PDLC), a dye-polymer-dispersed liquid crystal film (D-PDLC), a suspended particle film (SPD), a dye liquid crystal film (LC), or an electrochromic film (EC). The second conductive layer 121 and the third conductive layer 123 are typically made of materials with good conductivity, such as metal thin films, metal meshes, indium tin oxide (ITO), nano-silver, conductive polymer materials, etc. In some other embodiments, the dimming function layer 120 may also include a scattering layer, an angle control layer, etc., which are used to achieve light scattering, refraction, etc.

[0036] In one embodiment, such as Figure 3 As shown, the composite dimming assembly also includes a first protective layer 150 and a second protective layer 160, wherein the first protective layer 150 covers the first substrate layer 110 and the second protective layer 160 covers the light-emitting element layer 142.

[0037] Specifically, to facilitate the transportation and storage of the composite dimming assembly, this embodiment protects the entire composite dimming assembly by providing a first protective layer 150 and a second protective layer 160. The first protective layer 150 covers the side of the first substrate layer 110 that is not in contact with the dimming functional layer 120, and the second protective layer 160 covers the side of the light-emitting element layer 142 that is not in contact with the first conductive layer 141. The first protective layer 150 and the second protective layer 160 can be made of materials with high hardness, high wear resistance, and high chemical stability, such as hard coating materials (e.g., diamond films, diamond-like carbon films, etc.), polymer protective films (e.g., polyester films, polyimide films, etc.), or inorganic-organic composite protective films. The first protective layer 150 can resist mechanical damage such as scratches and impacts from external objects, thereby protecting the first substrate layer 110 from damage. It can also block the erosion of chemicals such as moisture, oxygen, and corrosive gases, preventing the first substrate layer 110 from chemical corrosion or aging. The second protective layer 160 can also resist mechanical damage such as scratches and impacts from external objects, thereby protecting the light-emitting element layer 142 from damage. It also blocks the erosion of chemicals such as moisture, oxygen, and corrosive gases, preventing chemical corrosion or aging of the light-emitting element layer 142. By setting protective layers, the storage life of the composite dimming component can be improved, and damage caused during transportation can be reduced. It is understood that when the composite dimming component needs to be used for other processing operations, the first protective layer 150 and the second protective layer 160 can be removed.

[0038] In one embodiment, such as Figure 4 As shown, the composite dimming assembly further includes: a first connecting layer 171, one side of the first connecting layer 171 being electrically connected to the first conductive layer 141, and the other side of the first connecting layer 171 being electrically connected to the first flexible circuit board 181.

[0039] Specifically, the composite dimming component in this embodiment also integrates a first flexible circuit board 181. In use, the first flexible circuit board 181 can be directly connected to an external circuit (such as via gold fingers, connectors, etc.), facilitating subsequent installation and use. The first flexible circuit board 181 is electrically connected to the first conductive layer 141 via a first connecting layer 171, providing corresponding electrical drive signals to the first conductive layer 141. The first connecting layer 171 is made of a material with good conductivity, such as conductive adhesive, conductive film (such as metal film, conductive polymer film), or anisotropic conductive film (ACF). In some embodiments, to enhance the adhesion between the first connecting layer 171 and the first conductive layer 141 and the first flexible circuit board 181, the surface of the first connecting layer 171 can be specially treated, such as roughening, chemical etching, or coating with an adhesion layer, to ensure stable electrical connection. It is understood that the first connecting layer 171 can adopt a patterned design, and it only needs to be set in the area on the first conductive layer 141 where electrical connection is required.

[0040] In one embodiment, such as Figure 5 As shown, the composite dimming assembly further includes: a second connecting layer 172 and a third connecting layer 173. One side of the second connecting layer 172 is electrically connected to the second conductive layer 121, and the other side of the second connecting layer 172 is electrically connected to the second flexible circuit board 182. One side of the third connecting layer 173 is electrically connected to the third conductive layer 123, and the other side of the third connecting layer 173 is electrically connected to the third flexible circuit board 183.

[0041] Specifically, in this embodiment, when the composite dimming component is provided with a second conductive layer 121, a dimming element layer 122, and a third conductive layer 123, the composite dimming component also integrates a second flexible circuit board 182 and a third flexible circuit board 183. In use, the second flexible circuit board 182 and the third flexible circuit board 183 can be directly connected to an external circuit (such as through gold fingers, connectors, etc.), facilitating subsequent installation and use. The second flexible circuit board 182 is electrically connected to the second conductive layer 121 through a second connecting layer 172, and the third flexible circuit board 183 is electrically connected to the third conductive layer 123 through a third connecting layer 173. The second flexible circuit board 182 and the third flexible circuit board 183 serve as connection electrodes for the light-emitting functional layer 140, jointly providing corresponding electrical drive signals to the dimming element layer 122. The second connecting layer 172 and the third connecting layer 173 are made of materials with good conductivity, such as conductive adhesive, conductive film (such as metal film, conductive polymer film), or anisotropic conductive film (ACF), etc. In some embodiments, to enhance the adhesion between the second connecting layer 172 and the second conductive layer 121 and the second flexible circuit board 182, and the adhesion between the third connecting layer 173 and the third conductive layer 123 and the third flexible circuit board 183, the surfaces of the second connecting layer 172 and the third connecting layer 173 may undergo special treatment, such as roughening, chemical etching, or coating with an adhesion layer, to ensure stable electrical connections. It is understood that the second connecting layer 172 and the third connecting layer 173 may employ a patterned design, requiring only that they be disposed on the areas of the second conductive layer 121 and the third conductive layer 123 where electrical connections are required.

[0042] In one embodiment, such as Figure 6 As shown, this application also proposes a composite dimming glass, comprising: a first glass layer 210, a first adhesive layer 220, a second glass layer 230, a second adhesive layer 240, and the composite dimming component in the above embodiment. The first glass layer 210 is bonded to the first substrate layer 110 of the composite dimming component through the first adhesive layer 220, and the second glass layer 230 is bonded to the light-emitting element layer 142 of the composite dimming component through the second adhesive layer 240.

[0043] Specifically, this embodiment also proposes a composite dimming glass including the aforementioned composite dimming component. The first glass layer 210 and the second glass layer 230 are bonded to the composite dimming component via a first adhesive layer 220 and a second adhesive layer 240, respectively, thereby forming a complete composite glass structure. The first glass layer 210 and the second glass layer 230 are made of transparent glass (such as float glass or tempered glass), serving as the outer layer structure to resist external impacts, scratches, and environmental corrosion. In some embodiments, the first glass layer 210 and the second glass layer 230 can also be made of Low-E glass to enhance the thermal insulation performance of the composite dimming glass. In one embodiment, the first adhesive layer 220 and the second adhesive layer 240 are one of polyvinyl butyral (PVB), polyethylene-vinyl acetate copolymer (EVA), and ethylene-methacrylic acid copolymer (SGP), used to tightly bond the glass layers to the composite dimming component. It is understandable that when a first protective layer 150 and a second protective layer 160 are provided on the composite dimming component, the first protective layer 150 and the second protective layer 160 need to be removed when bonding the glass layer to the composite dimming component.

[0044] In one embodiment, such as Figure 7 As shown, the dimming functional layer 120 of the composite dimming assembly of the composite dimming glass includes a second conductive layer 121, a dimming element layer 122, and a third conductive layer 123 stacked sequentially. The composite dimming assembly also includes a first connecting layer 171, a second connecting layer 172, and a third connecting layer 173. One side of the first connecting layer 171 is electrically connected to the first conductive layer 141, and the other side of the first connecting layer 171 is electrically connected to the first flexible circuit board 181. The other side of the second connecting layer 172 is electrically connected to the second flexible circuit board 182. One side of the third connecting layer 173 is electrically connected to the third conductive layer 123, and the other side of the third connecting layer 173 is electrically connected to the third flexible circuit board 183.

[0045] The advantages of the composite dimming glass of this application are described in detail below with a specific embodiment. For example... Figure 8As shown, in one embodiment, a composite dimming glass 330 manufactured using conventional technology is formed by laminating an independently structured dimming component 310 and an independently structured light-emitting component 320. The independently structured dimming component 310 includes a protective layer 301, a substrate layer 302, a conductive layer 303, a dimming layer 304, a conductive layer 303, a substrate layer 302, and a protective layer 301 stacked sequentially. The conductive layers 303 are all electrically connected to the flexible circuit board 305 via connecting layers 306. The independently structured dimming component 310 has two substrate layers 302. The independently structured light-emitting component 320 includes a protective layer 301, a substrate layer 302, a conductive layer 303, a light-emitting layer 307, and a protective layer 301 stacked sequentially. The conductive layer 303 is also electrically connected to the flexible circuit board 305 via connecting layers 306. The independently structured light-emitting component 320 has one substrate layer 302. During lamination, the protective layers 301 of the dimming component 310 and the light-emitting component 320 are removed, and the substrate layers 302 of the dimming component 310 and the light-emitting component 320 are bonded together using adhesive layers 309. Glass layers 308 are then bonded to the top and bottom sides of the formed structure using adhesive layers 309 to form a composite dimming glass 330. At this point, the composite dimming glass 330 contains three substrate layers 302. However, during the lamination process, insufficient matching can easily occur, leading to pattern misalignment and potentially causing rainbow patterns in the laminated composite dimming glass 330. Figure 7 As shown, the composite dimming glass of this application solves the problem of lamination misalignment and the rainbow pattern caused by lamination by setting the middle substrate layer as a double-sided conductive layer. At the same time, by adopting the structure of setting the middle substrate layer as a double-sided conductive layer, the composite dimming glass is reduced from three substrate layers to two substrate layers, making the overall thickness of the composite dimming glass thinner.

[0046] In one embodiment, this application also proposes a vehicle, which includes the composite dimming glass described in the above embodiments. The composite dimming glass can be a sunroof, side door glass, corner window glass, etc., of the vehicle. The vehicle can include land vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment, etc. For example, the vehicle can be a vehicle, which is a vehicle in a broad sense, including transportation vehicles (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, harvesters, etc.), amusement equipment, toy vehicles, etc. This application does not specifically limit the type of vehicle. Furthermore, the vehicle can be an airplane or a ship, etc.
