Abstract

The application discloses a sunshade curtain assembly, a glass assembly and a vehicle. The sunshade curtain assembly comprises a first curtain cloth, a second curtain cloth and a light-emitting component. The second curtain cloth is arranged in a laminated manner with the first curtain cloth.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the surface of the second curtain is provided with a light-functional coating, the refractive index of which is greater than the refractive index of the second curtain.

[0021] Thirdly, embodiments of this application provide a vehicle, including a vehicle body and a glass assembly as described above, the glass assembly being mounted on the vehicle body.

[0022] The sunshade assembly, glass assembly, and vehicle provided in this application embodiment are based on fixing the light-emitting component between the first and second curtain fabrics and placing the light-emitting delay structure on the emission path of the emitted light provided by the light-emitting component. On the one hand, the light-emitting delay structure can emit light after being excited by the emitted light provided by the light-emitting component, and after the light-emitting component is turned off, the light-emitting delay structure can continue to emit light for a period of time, extending the light-emitting time of the sunshade assembly. Thus, given a fixed total light-emitting time, the working time of the light-emitting component can be shortened, extending the service life of the light-emitting component. Furthermore, the light-emitting delay structure can avoid sudden changes in light, creating a soft light and shadow transition, and meeting the requirements of use in extreme environments such as high temperature and high humidity. The scenario requires that, on the other hand, since the light-emitting component is closely attached to the second curtain, the problem of leakage or scattering of the emitted light provided by the light-emitting component, which would cause the intensity of the emitted light to decrease, is avoided. As a result, most of the emitted light provided by the light-emitting component can be projected onto the light-emitting delay structure, improving the light-emitting effect and display effect of the light-emitting delay structure. Furthermore, the first and second curtains are porous and flexible structures, which can avoid the problem of light being directly projected onto the glass and causing reflection when the light-emitting component is placed on the glass. This makes it easy to assemble the light-emitting component between the first and second curtains, and it eliminates the need to disassemble the glass body when the light-emitting component malfunctions, reducing the maintenance cost of the sunshade assembly.

[0044] The following description provides preferred embodiments for carrying out this application; however, this description is for the purpose of illustrating the general principles of this application and is not intended to limit the scope of this application. The scope of protection of this application shall be determined by the appended claims.

[0045] The basic concepts involved in the embodiments of this application will be briefly introduced below.

[0046] The term "light-emitting delay material" refers to a material that continues to emit light after external excitation (such as light, electricity, radiation, etc.) has ceased. The duration of light emission in light-emitting delay materials ranges from milliseconds to several hours. For example, in this embodiment, the light-emitting delay material is a material that emits light under the excitation of excitation light.

[0048] The term "transmittance" refers to the ability of light to pass through a sunshade, which is the percentage between transmitted light flux and incident light flux. Incident light flux is the intensity of natural or artificial light when unblocked, while transmitted light flux is the intensity of light after passing through the sunshade.

[0049] The term "coating" refers to the process of uniformly, continuously, and controllably applying a coating material in a fluid or semi-fluid state to a substrate to form a thin film with specific functions and thickness.

[0050] Please refer to the following: Figures 1 to 2 , Figure 1 This is a structural schematic diagram of the vehicle 1000 provided in the embodiments of this application; Figure 2 yes Figure 1 A cross-sectional view of a first embodiment of the glass assembly 200 of a vehicle 1000. The vehicle 1000 includes a body 100 and a glass assembly 200. The glass assembly 200 is mounted on the body 100.

[0051] The glass assembly 200 includes a sunshade assembly 300 and a glass body 400. The sunshade assembly 300 is attached to the glass body 400. The sunshade assembly 300 is located on the side of the glass body 400 facing the interior of the vehicle 1000. Therefore, on the one hand, the sunshade assembly 300 can block most of the ambient light from outside the vehicle 1000, thereby reducing the interior temperature, reducing the air conditioning load, and preventing external views while maintaining visibility inside the vehicle; on the other hand, the sunshade assembly 300 can provide ambient lighting and functional light sources, improving the user experience for drivers and passengers.

[0052] In this embodiment, the vehicle 1000 also includes a vehicle body 100. An opening 101 is provided on the vehicle body 100, and a glass body 400 is installed at the opening 101. A sunshade assembly 300 is located on the side of the glass body 400 facing the interior of the vehicle 1000, thereby enabling the sunshade assembly 300 to provide ambient lighting and functional light sources inside the vehicle, improving the user experience for passengers.

[0053] The glass assembly may include, but is not limited to, a sunroof glass assembly, front and rear window glass assemblies, and side window glass assemblies. In this embodiment, the glass assembly 200 is described using a sunroof glass assembly as an example. Of course, in some embodiments, the glass assembly 200 may also be configured as a front and rear windshield glass assembly, a ventilation window glass assembly, or other glass assemblies; this application does not specifically limit the configuration.

[0054] Vehicle 1000 may include, but is not limited to, cars, sports cars, trains, and other driving devices; this application embodiment does not impose such limitations. It is understood that, to enable those skilled in the art to better understand the sunshade assembly 300, the sunshade assembly 300 is described in detail using an application to a car as an example. It should be noted that the application of the sunshade assembly 300 to a car is for illustrative purposes only, and this application embodiment does not impose specific limitations. For example, the product application of the sunshade assembly 300 can be configured according to actual needs.

[0055] It should be noted that, Figure 1 The purpose is merely to illustrate the arrangement between the vehicle body 100 and the glass assembly 200, and is not to make specific limitations on the connection positions, connection relationships and specific structures of the various components. Figure 1 The structure of the vehicle 1000 illustrated in this embodiment is merely a schematic diagram and does not constitute a specific limitation on the vehicle 1000. In other embodiments of this application, the vehicle 1000 may include... Figure 1 The vehicle may include more or fewer components, or combinations of certain components, or different components, such as wheels, seats, or power mechanisms, etc.

[0056] Please see Figure 2 The sunshade assembly 300 includes a first curtain 1, a second curtain 2, and a light-emitting component 3. The second curtain 2 is stacked on top of the first curtain 1. The light-emitting component 3 is fixed between the first curtain 1 and the second curtain 2, and the emitted light provided by the light-emitting component 3 is emitted into the interior of the vehicle 1000 via the second curtain 2. A light-emitting delay structure 7 is disposed in the emission path of the emitted light, and the material of the light-emitting delay structure 7 includes a light-emitting delay material. The light-emitting delay material is used to emit light in response to the excitation of the emitted light.

[0057] The sunshade assembly 300 provided in this application embodiment is based on fixing the light-emitting component 3 between the first curtain 1 and the second curtain 2, and placing the light-emitting delay structure 7 on the emission path of the emitted light provided by the light-emitting component 3. On the one hand, the light-emitting delay structure 7 can emit light after being excited by the emitted light provided by the light-emitting component 3, and after the light-emitting component 3 is turned off, the light-emitting delay structure 7 can continue to emit light for a period of time, extending the light-emitting time of the light-emitting component 3. Thus, given a fixed total light-emitting time, the working time of the light-emitting component 3 can be shortened, extending the service life of the light-emitting component 3. Furthermore, the light-emitting delay structure 7 can avoid sudden changes in light, creating a soft light and shadow transition, and meeting the requirements of extreme environments such as high temperature and high humidity. Application scenario requirements; on the other hand, since the light-emitting component 3 is closely attached to the second curtain 2, the problem of scattering of the emitted light provided by the light-emitting component 3 and blurring of the edges of the pattern displayed by the sunshade assembly 300 is avoided. As a result, most of the emitted light provided by the light-emitting component 3 can be projected onto the light-emitting delay structure 7, improving the light-emitting effect and display effect of the light-emitting delay structure 7. Furthermore, the first curtain 1 and the second curtain 2 are porous and flexible structures, which can avoid the problem of light being directly projected onto the glass and forming reflection when the light-emitting component 3 is placed on the glass. This makes it easy for the light-emitting component 3 to be assembled between the first curtain 1 and the second curtain 2, and there is no need to disassemble the glass body 400 when the light-emitting component 3 malfunctions.

[0058] It should be noted that the emission path of the emitted light refers to the emission direction F and spatial trajectory of the light emitted from the light-emitting component 3. The emission direction F is determined by the direction of light propagation at the emission point of the light-emitting component 3, specifically the path taken by the emitted light from the light-emitting component 3 as it travels towards the human eye. The spatial trajectory refers to the straight or curved path of the emitted light after exiting the light-emitting component 3 in free space or the next medium. For example, in this embodiment, the emission direction F refers to the direction of the emitted light provided by the light-emitting component 3 toward the interior of the vehicle body 100 and perpendicular to the plane where the second curtain 2 is located. The emission path refers to the straight path of the emitted light after exiting the light-emitting component 3 in the second curtain 2.

[0059] Please refer to the following: Figures 2 to 4 , Figure 3 yes Figure 1 A cross-sectional view of a second embodiment of the sunshade assembly 300 of the vehicle 1000; Figure 4 yes Figure 2A cross-sectional view of the first embodiment of the light-emitting component 3 of the sunshade assembly 300. A light-emitting delay structure 7 is disposed in at least one of the light-emitting component 3 and the second curtain 2. Specifically, the light-emitting delay structure 7 may be disposed between the light-emitting component 3 and the second curtain 2; and / or, the light-emitting delay structure 7 may be disposed on the side of the second curtain 2 facing away from the light-emitting component 3; and / or, the light-emitting delay material may be distributed in at least one of the second curtain 2 and the light-emitting component 3.

[0060] like Figure 2 As shown, the light-emitting delay structure 7 can be disposed between the light-emitting component 3 and the second curtain 2. Therefore, by disposing the light-emitting delay structure 7 between the light-emitting component 3 and the second curtain 2, the problem of blurred boundaries of the light-emitting pattern and attenuation of the emitted light due to scattering of emitted light caused by the distance between the light-emitting component 3 and the light-emitting delay structure 7 is avoided. Of course, in some embodiments, the light-emitting delay structure 7 can be disposed on the side of the second curtain 2 facing away from the light-emitting component 3.

[0061] like Figure 3 As shown, the light-emitting delay material is distributed in the second curtain 2. Specifically, the light-emitting delay material is blended in the second curtain 2. Therefore, based on the distribution of the light-emitting delay material in the second curtain 2, since the material of the second curtain 2 is usually translucent or scattering, the sunshade assembly 300 can convert point light sources into surface light sources, making the light more uniform and softer, reducing glare, and improving the quality of the in-vehicle atmosphere.

[0062] like Figure 4 As shown, the light-emitting delay material is distributed in the light-emitting component 3. Therefore, by distributing the light-emitting delay material in the light-emitting component 3, the light transmittance of the through holes in the second curtain 2 is avoided from affecting the light-emitting effect of the light-emitting delay structure 7, and the resistance of the light-emitting delay structure 7 to ambient light interference is improved.

[0063] The luminescent delay material is a long-afterglow luminescent material, which may include, but is not limited to, at least one of strontium aluminate materials, photoluminescent quantum dot materials, and aggregation-induced emission materials. Strontium aluminate materials may include, but are not limited to, strontium aluminate materials doped with rare earth ions, or strontium aluminate materials doped with europium and / or dysprosium. Photoluminescent quantum dot materials may include, but are not limited to, at least one of semiconductor quantum dot materials, perovskite quantum dot materials, carbon quantum dot materials, and silicon quantum dot materials. Aggregation-induced emission materials may include, but are not limited to, tetraphenylethylene and its derivatives.

[0064] In some embodiments, the material of the light-emitting delay structure 7 may further include a dispersion material. The dispersion material may include, but is not limited to, at least one of polyester, epoxy polymer, acrylate polymer, etc. Thus, on the one hand, the dispersion material can serve as a carrier and framework for the light-emitting delay material to form a thin film-like structure, thereby improving the mechanical strength and toughness of the light-emitting delay structure 7, enhancing its processing performance, and enriching its application forms; on the other hand, the dispersion material can encapsulate the light-emitting delay material, forming a physical barrier to protect it from direct erosion by external environments such as moisture, oxygen, dust, acids, and alkalis, thereby extending the lifespan and stability of the light-emitting delay material.

[0065] The excitation light emitted by the light-emitting component 3 is used to excite the light-emitting delay material of the light-emitting delay structure 7 to emit light. The light-emitting component 3 includes, but is not limited to, an AC electroluminescent film, a DC electroluminescent film, a light-emitting diode (LED) lamp bead, or an organic electroluminescence display (OLED) film. Exemplarily, in this embodiment, the light-emitting component 3 is configured as an AC electroluminescent film. LED lamp beads include polymer LEDs or quantum dot LEDs. Thus, on the one hand, the AC electroluminescent film can be seamlessly embedded between the first curtain 1 and the second curtain 2 without increasing the mechanical volume of the light-emitting blackout curtain, facilitating the rolling and unfolding functions of the light-emitting blackout curtain; on the other hand, the AC electroluminescent film can meet the needs of multiple scenarios such as driving and warning through delay response and gradual control. Of course, in some embodiments, the product type of the light-emitting component 3 can be set according to factors such as the light efficiency performance, mechanical adaptability, vehicle environment reliability, and cost of the light-emitting blackout curtain, and this application embodiment does not make specific limitations.

[0066] Please refer to the following: Figures 2 to 10 , Figure 5 yes Figure 2 A cross-sectional view of the light-emitting component 3 of the sunshade assembly 300 in the second embodiment. Figure 6 yes Figure 2 A cross-sectional view of the light-emitting component 3 of the sunshade assembly 300 in the third embodiment. Figure 7 yes Figure 2 A cross-sectional view of the light-emitting component 3 of the sunshade assembly 300 in the fourth embodiment. Figure 8 yes Figure 2 A cross-sectional view of the light-emitting component 3 of the sunshade assembly 300 in the fifth embodiment. Figure 9 yes Figure 2 A cross-sectional view of the light-emitting component 3 of the sunshade assembly 300 in the sixth embodiment. Figure 10 yes Figure 2A cross-sectional view of the seventh embodiment of the light-emitting component 3 of the sunshade assembly 300. The light-emitting component 3 includes a first conductive layer 31, a light-emitting layer 32, and a second conductive layer 33. The first conductive layer 31, the light-emitting layer 32, and the second conductive layer 33 are arranged sequentially in the emission direction F of the emitted light. A light-emitting delay structure 7 is disposed between the light-emitting layer 32 and the second conductive layer 33; and / or, the light-emitting delay structure 7 is disposed on the surface of the second conductive layer 33 facing away from the light-emitting layer 32; and / or, the light-emitting delay material is distributed in at least one of the second conductive layer 33 and the light-emitting layer 32.

[0067] like Figure 4 As shown, the light-emitting delay structure 7 is disposed between the light-emitting layer 32 and the second conductive layer 33. Figure 5 As shown, in the second embodiment, the light-emitting delay structure 7 may not be disposed on the light-emitting component 3, that is, the light-emitting delay structure 7 is disposed independently in the area outside the light-emitting component 3.

[0068] like Figure 6 and Figure 7 As shown, in some embodiments, the light-emitting delay structure 7 is disposed on the side of the second conductive layer 33 opposite to the light-emitting layer 32, and / or, the light-emitting delay material is distributed in the second conductive layer 33. Therefore, due to the slight difference in response time that may exist at different positions of the light-emitting layer 32 under AC drive, by disposing the light-emitting delay structure 7 on the side of the second conductive layer 33 opposite to the light-emitting layer 32, and / or distributing the light-emitting delay material in the second conductive layer 33, on the one hand, the second conductive layer 33 can homogenize the light from the light-emitting layer 32, so that the emitted light from all areas of the light-emitting layer 32 reaches the observer's eye almost simultaneously, reducing flicker or ghosting, and softening the edges of light spots / pixels, making the transition between the light-emitting and non-light-emitting areas of the light-emitting curtain smoother, thus improving... Visual comfort; on the other hand, based on distributing the light-emitting delay material in the second conductive layer 33 so that the light-emitting delay material can be uniformly dispersed in the second conductive layer 33, on the one hand, it can avoid optical or electrical non-uniformity caused by local aggregation of the light-emitting delay material; on the other hand, there is no additional interface layer between the light-emitting delay structure 7 and the second conductive layer 33, which reduces the reflection loss of the emitted light provided by the light-emitting component 3 at the multi-layer interface and reduces the stress problem caused by the mismatch of the interface thermal expansion coefficient; furthermore, it avoids the problem of the light-emitting delay structure 7 damaging the light-emitting component 3 during the manufacturing process.

[0069] like Figure 10As shown, in this embodiment, the light-emitting layer 32 is configured as an electroluminescent layer 321. Specifically, the light-emitting layer 32 can be configured as a single-layer structure containing electroluminescent material. In some embodiments, the light-emitting layer 32 may further include an electroluminescent layer 321 and a dielectric layer 322. The dielectric layer 322 is disposed between the second conductive layer 33 and the electroluminescent layer 321. A light-emitting delay structure 7 is disposed between the dielectric layer 322 and the electroluminescent layer 321; and / or, the light-emitting delay structure 7 is disposed on the side of the dielectric layer 322 facing away from the electroluminescent layer 321; and / or, the light-emitting delay material is distributed in the dielectric layer 322. Of course, in some embodiments, the dielectric layer 322 may also be disposed between the electroluminescent layer 321 and the first conductive layer 31, and the dielectric layer 322 located between the electroluminescent layer 321 and the first conductive layer 31 does not have a light-emitting delay structure 7.

[0070] It should be noted that the electroluminescent layer 321 refers to a film layer containing electroluminescent material. For example, the electroluminescent material in the electroluminescent layer 321 is formed by mixing with a dispersion material and then curing; or, the electroluminescent material in the electroluminescent layer 321 is formed by mixing with a dispersion material and then coating onto at least one surface of a supporting substrate to form the electroluminescent layer 321; or, the electroluminescent material in the electroluminescent layer 321 is formed on a dielectric layer 322 or a supporting substrate by deposition to form the electroluminescent layer 321. The formation method of the electroluminescent layer 321 can be set according to the actual situation, and the embodiments of this application do not specifically limit it. The coating methods mentioned herein include, but are not limited to, spraying, inkjet printing, roller coating, screen printing, slot coating, microgravure coating, doctor blade coating, dip coating, electrospray deposition, etc. The deposition methods include, but are not limited to, physical vapor deposition (PVD), chemical vapor deposition (CVD), and liquid phase deposition, etc.

[0071] Please refer to it again. Figures 6 to 8The second conductive layer 33 includes a conductive base layer 331 and an encapsulation layer 332. The conductive base layer 331 is disposed between the encapsulation layer 332 and the light-emitting layer 32. A light-emitting delay material is blended within the conductive base layer 331 and / or the encapsulation layer 332. The conductive base layer 331 and the encapsulation layer 332 include transparent regions for emitting light provided by the light-emitting layer 32. The conductive base layer 331 may be configured as a conductive film layer containing a conductive material; alternatively, the conductive base layer 331 may also be configured as an electronically conductive structure. For example, the conductive material includes, but is not limited to, at least one of Ag, Cu, and indium tin oxide (ITO). The electronically conductive structure may be configured as, but is not limited to, a metal wire or a conductive tape, and is used to electrically connect an external power source and an ion-conducting structure. In some embodiments, when the conductive base layer 331 is used to form a surface electric field, the ion-conducting structure may be configured as an ion gel. The encapsulation layer 332 is used to protect the conductive structure of the conductive base layer 331. The encapsulation layer 332 may be configured as, but is not limited to, a support film comprising a flexible material; or, the encapsulation layer 332 may also be configured as an adhesive layer, a tape layer, or other protective layer. The flexible material includes, but is not limited to, at least one of polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), polycarbonate (PC), or polyvinyl acetate (PVAc).

[0072] like Figures 7 to 8 As shown, the light-emitting delay structure 7 and the second conductive layer 33 are independently disposed and fixedly connected. For example, the light-emitting delay structure 7 is formed on the second conductive layer 33 by means of coating, plating, or bonding. Therefore, by attaching the light-emitting delay structure 7 as an independent layer to the second conductive layer 33, the thickness, regional distribution, and material formulation of the light-emitting delay structure 7 in the manufacturing process can be flexibly controlled, and the problems of adding light-emitting delay material to the conductive base layer 331 and affecting the conductivity of the conductive base layer 331, and adding light-emitting delay material to the encapsulation layer 332 and affecting the light transmittance of the second conductive layer 33 are avoided.

[0073] like Figure 6 As shown, the light-emitting delay material is distributed in the encapsulation layer 332. Specifically, the light-emitting delay material is co-distributed in the encapsulation layer 332. Of course, in some embodiments, the light-emitting delay material is distributed in the conductive base layer 331; or, the light-emitting delay material is simultaneously distributed in the conductive base layer 331 and the encapsulation layer 332. Specifically, the light-emitting delay material is co-distributed in the conductive base layer 331; or, the light-emitting delay material is co-distributed in the conductive base layer 331 and the encapsulation layer 332.

[0074] Specifically, such as Figure 7 and Figure 8 As shown, the conductive base layer 331 and the encapsulation layer 332 are connected to form an integral structure. The light-emitting delay structure 7 is disposed on the side of the conductive base layer 331 facing the light-emitting layer 32; or, the light-emitting delay structure 7 is disposed on the side of the encapsulation layer 332 facing away from the conductive base layer 331. Thus, based on the integral structure formed by connecting the conductive base layer 331 and the encapsulation layer 332, on the one hand, the encapsulation layer 332 can serve as a support structure for the conductive base layer 331, reducing the processing difficulty of the conductive base layer 331; on the other hand, the conductive base layer 331 and the encapsulation layer 332 can be fused into a single-layer or multi-layer composite structure through material modification or lamination processes, so that the second conductive layer 33 has both conductive and encapsulation protection functions, as well as simplified interlayer interfaces, improving the mechanical flexibility and encapsulation reliability of the second conductive layer 33.

[0075] like Figure 9 As shown, the conductive substrate 331 and the light-emitting layer 32 are connected to form an integral structure. A light-emitting delay structure 7 is disposed between the conductive substrate 331 and the encapsulation layer 332; alternatively, the light-emitting delay structure 7 is disposed on the side of the encapsulation layer 332 facing away from the conductive substrate 331. Therefore, by connecting the conductive substrate 331 and the light-emitting layer 32 to form an integral structure, the contact resistance between the conductive substrate 331 and the light-emitting layer 32 is reduced, the current distribution uniformity is improved, and the light-emitting effect of the light-emitting component 3 is enhanced.

[0076] The first conductive layer 31 includes a flexible base layer 311 and a conductive main layer 312. The flexible base layer 311 is used to support and protect the conductive structure of the conductive main layer 312. The flexible base layer 311 can be configured as, but is not limited to, a support film containing a flexible material. Alternatively, the flexible base layer 311 can also be configured as an adhesive layer, a tape layer, or other protective layer. The flexible material includes, but is not limited to, at least one of polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), polycarbonate (PC), or polyvinyl acetate (PVAc). The conductive main layer 312 can be configured as a conductive film layer containing a conductive material; or, the conductive main layer 312 can also be configured as an electronically conductive structure. For example, the conductive material includes, but is not limited to, at least one of Ag, Cu, and indium tin oxide (ITO). The electronically conductive structure can be configured as, but is not limited to, a metal wire or a conductive tape, and is used for electrical connection to an external power source and an ion-conducting structure. In some embodiments, when the conductive host layer 312 is used to form a surface electric field, the ion-conducting structure can be configured as an ion gel.

[0077] It should be noted that the structure of the first conductive layer 31 may be the same as or different from the structure of the second conductive layer 33, and the embodiments of this application do not impose specific limitations.

[0078] Please refer to it again. Figure 11 , Figure 11 yes Figure 1 A cross-sectional view of the glass assembly 200 of the vehicle 1000 in the third embodiment. The light-emitting component 3 is fixedly connected to the first curtain 1 and the second curtain 2 by adhesive bonding. Specifically, the sunshade assembly 300 also includes a first adhesive layer 4 and a second adhesive layer 5. The first adhesive layer 4 is disposed on the side of the first curtain 1 facing the second curtain 2. The second adhesive layer 5 is disposed on the side of the second curtain 2 facing the first curtain 1, and the light-emitting component 3 is bonded between the first adhesive layer 4 and the second adhesive layer 5. Therefore, on the one hand, the first adhesive layer 4 and the second adhesive layer 5 firmly bond the light-emitting component 3 between the first curtain 1 and the second curtain 2, thereby avoiding the problem of frictional displacement between the light-emitting component 3 and the first curtain 1 and the second curtain 2 during the opening and closing of the sunshade assembly 300. In addition, the first adhesive layer 4 and the second adhesive layer 5 absorb the bending stress of the first curtain 1 and the second curtain 2, thereby reducing the risk of breakage of the light-emitting component 3. On the other hand, the first adhesive layer 4 and the second adhesive layer 5 cover the edge of the light-emitting component 3, preventing moisture from entering the light-emitting component 3, extending the service life of the light-emitting component 3, and preventing dust from entering the gap of the light-emitting layer 32 and causing local dark spots. Furthermore, the light-emitting component 3 does not require an additional installation structure, has a simple structure, and achieves a lightweight and thin design for the light-emitting sunshade.

[0079] In this embodiment, the sunshade assembly 300 further includes a third adhesive layer 6. The third adhesive layer 6 is bonded to the periphery of the light-emitting component 3 and to the first adhesive layer 4 and the second adhesive layer 5, thereby preventing moisture from entering the light-emitting component 3, extending its service life, and preventing dust from entering the gaps in the light-emitting layer 32 and causing localized dark spots. Of course, in some embodiments, when the thickness of the light-emitting component 3 is less than a preset thickness, the third adhesive layer 6 can be omitted; that is, the first adhesive layer 4 and the second adhesive layer 5 encapsulate the light-emitting component 3 to isolate it from the outside air. The preset thickness can be set according to actual conditions, and this embodiment does not impose specific limitations.

[0080] In some embodiments, the light-emitting component 3 can also be fixedly connected between the first curtain 1 and the second curtain 2 by sewing, clipping, Velcro, or other methods. This application does not specifically limit the specific methods described. Figure 2As shown, the light-emitting component 3 is fixedly connected to the first curtain 1 and the second curtain 2 by stitching. The sunshade assembly 300 may also include an auxiliary adhesive layer 9. The auxiliary adhesive layer 9 is disposed around the periphery of the light-emitting component 3 and is bonded between the first curtain 1 and the second curtain.

[0081] Please refer to the following: Figures 11 to 15 , Figure 12 yes Figure 1 A cross-sectional view of a fourth embodiment of the sunshade assembly 300 of the vehicle 1000; Figure 13 yes Figure 1 A cross-sectional view of the fifth embodiment of the sunshade assembly 300 of the vehicle 1000; Figure 14 yes Figure 1 A cross-sectional view of the sixth embodiment of the sunshade assembly 300 of the vehicle 1000; and Figure 15 yes Figure 1 A cross-sectional view of the seventh embodiment of the sunshade assembly 300 of the vehicle 1000. A light-emitting delay material is distributed in the second adhesive layer 5; and / or, a light-emitting delay structure 7 is disposed between the light-emitting component 3 and the second adhesive layer 5; and / or, a light-emitting delay structure 7 is disposed between the second adhesive layer 5 and the second curtain fabric 2; and / or, a light-emitting delay structure 7 is disposed on the side of the second curtain fabric 2 facing away from the second adhesive layer 5.

[0082] like Figure 11 As shown, in some embodiments, the light-emitting delay structure 7 is disposed between the second adhesive layer 5 and the second curtain fabric 2, thereby providing good physical protection for the light-emitting delay structure 7 between the second adhesive layer 5 and the second curtain fabric 2, reducing the risk of the light-emitting delay structure 7 being scratched and falling off. Specifically, when the light-emitting delay material of the light-emitting delay structure 7 can be formed by coating on the side of the second adhesive layer 5 near the second curtain fabric 2, it is understood that the light-emitting delay material will seep into the through holes of the second curtain fabric 2, thereby increasing the light-emitting area. In this embodiment, by making the coating corresponding to the light-emitting delay material thicker than or equal to 100 μm after curing, the transmittance of the light-emitting delay structure 7 is made greater than or equal to 50%, thereby reducing the light loss and manufacturing cost of the light-emitting delay structure 7. Of course, in some embodiments, the light-emitting delay material of the light-emitting delay structure 7 can also form an integral structure with the dispersion material, and then be bonded to the side of the second adhesive layer 5 near the second curtain fabric 2, thereby preventing the light-emitting delay material from seeping into the through holes of the second curtain fabric 2.

[0083] like Figure 12As shown, the light-emitting delay material of the light-emitting delay structure 7 is mixed in the second adhesive layer 5. On the one hand, the second adhesive layer 5 plays a dual role in fixing the light-emitting component 3 and optical control, eliminating the need for an independent optical film layer, thereby reducing the thickness of the light-emitting shading curtain and reducing production costs. On the other hand, the second adhesive layer 5 can still completely cover the edge of the light-emitting component 3, blocking water and oxygen, thereby extending the service life of the light-emitting component 3.

[0084] Of course, in some embodiments, the light-emitting delay material of the light-emitting delay structure 7 can also be mixed into the second curtain fabric 2. This avoids the problem of the light-emitting delay material settling due to softening of the second adhesive layer 5, which would otherwise occur when the light-emitting delay material is mixed into the second adhesive layer 5. This allows the sunshade assembly 300 to meet the requirements of high-temperature extreme environments and improves the light-emitting effect and quality of the sunshade assembly 300.

[0085] like Figure 13 As shown, the light-emitting delay structure 7 is disposed between the light-emitting component 3 and the second adhesive layer 5, thereby avoiding the scattering and absorption of the emitted light provided by the light-emitting component 3 by the second adhesive layer 5 and the second curtain 2, improving the absorption of the emitted light velocity by the light-emitting delay structure 7, thereby improving the delay efficiency of the light-emitting delay structure 7, and improving the light-emitting effect and light-emitting quality of the sunshade assembly 300.

[0086] like Figure 14 The light-emitting delay structure 7 is disposed between the second adhesive layer 5 and the second curtain 2, and the second adhesive layer 5 covers the four edges of the light-emitting delay structure 7, thereby preventing the light-emitting delay structure 7 from being exposed to the external environment and protecting the structure of the light-emitting delay material from damage.

[0087] like Figure 15As shown, the light-emitting delay structure 7 is disposed on the side of the second curtain 2 facing away from the second adhesive layer 5. Therefore, on the one hand, the light-emitting delay structure 7 can block the through-holes of the corresponding portion of the second curtain 2, thereby preventing light leakage from the through-holes of the second curtain 2 and improving the aesthetic appeal of the sunshade assembly 300. On the other hand, the light-emitting delay structure 7 is directly exposed on the outside of the second curtain 2, allowing the light emitted by the light-emitting delay structure 7 to shine outwards and diffuse without obstruction, ensuring that the light-emitting pattern of the light-emitting extension structure can be clearly seen by the user, and reducing the absorption, scattering, or blocking of light by the second curtain 2 and the second adhesive layer 5, thus improving the brightness, uniformity, and visible range of the light-emitting delay structure 7. Specifically, the light-emitting delay material of the light-emitting delay structure 7 can be formed on the side of the second curtain 2 facing away from the second adhesive layer 5 by coating. The light-emitting delay material will seep into the through-holes of the second curtain 2, thereby increasing the light-emitting area of ​​the light-emitting delay structure 7. In this embodiment, by ensuring the coating thickness corresponding to the luminescent delay material is greater than or equal to 100 μm after curing, the transmittance of the luminescent delay structure 7 is greater than or equal to 50%, thereby reducing the light loss and manufacturing cost of the luminescent delay structure 7. Of course, in some embodiments, the luminescent delay material of the luminescent delay structure 7 can also form an integral structure with the dispersion material, and then be bonded to the side of the second curtain 2 opposite to the second adhesive layer 5, thereby preventing the luminescent delay material from seeping into the through-holes of the second curtain 2 and reducing the air permeability of the sunshade.

[0088] Understandably, when the light transmittance of the light-emitting delay structure 7 is too low, less light from the emitted light provided by the light-emitting component 3 is projected onto the light-emitting delay material inside the light-emitting delay structure 7. Consequently, the light-emitting delay structure 7 cannot store enough light energy, resulting in a short light-emitting time after the light-emitting component 3 is turned off, and a reduced visual effect. In some embodiments, the light transmittance of the light-emitting delay structure 7 is greater than or equal to 50%. Thus, on the one hand, setting the light transmittance of the light-emitting delay structure 7 within a suitable range can present a good visual effect, and ensure that the area corresponding to the light-emitting delay structure 7 can still emit light for a period of time after the light-emitting component 3 is turned off, shortening the working time of the light-emitting component 3 and extending the service life of the sunshade assembly 300.

[0089] Please refer to the following: Figure 1 and Figure 16 , Figure 16 yes Figure 1A cross-sectional view of the sunshade assembly 300 of the vehicle 1000 in the image. In some embodiments, a light-functional coating 8 is provided on the fiber surface of the second curtain 2. The refractive index of the light-functional coating 8 is greater than that of the second curtain 2. Therefore, based on the fact that the refractive index of the light-functional coating 8 is greater than that of the second curtain 2, the light-functional coating 8 can cause more total internal reflection of the emitted light provided by the light-emitting component 3 within the light-functional coating 8, and cause more of the emitted light provided by the light-emitting component 3 to act on the light-emitting delay material, thereby reducing light loss and preventing light leakage from the through-holes of the second curtain 2, thereby improving the aesthetic appearance of the sunshade assembly 300. The light-functional coating 8 can be provided on the side of the second curtain 2 near the second adhesive layer 5; or, the light-functional coating 8 can be provided on both the side of the second curtain 2 near the second adhesive layer 5 and the side of the second curtain 2 away from the second adhesive layer 5.

[0090] In some embodiments, the material of the light-functional coating 8 includes light-scattering particles. The particle size of the light-scattering particles is 0.02 μm-50 μm. Thus, on the one hand, the scattering particles can disperse and homogenize the emitted light provided by the light-emitting component 3 in multiple directions, so that the direct parallel light is converted into soft diffused light, thereby making the light inside the vehicle more uniform and soft, reducing glare, and preventing light leakage from the openings of the second curtain 2, thereby improving the aesthetics of the visual effect presented by the sunshade assembly 300 and enhancing the visual comfort of the driver and passengers; on the other hand, by setting the particle size of the light-scattering particles within a suitable range, the light-emitting delay structure 7 has a suitable light transmittance, thereby maintaining the optical stability of the light-functional coating 8, extending the service life of the sunshade assembly 300, and enabling the sunshade assembly 300 to have a good light-blocking effect, while also enabling the light-emitting delay structure 7 to present a good visual effect.

[0091] The particle size of the light-scattering particles can be, but is not limited to, 0.02 μm, 0.03 μm, 0.04 μm, 0.05 μm, 0.07 μm, 0.1 μm, 0.2 μm, 0.3 μm, 0.4 μm, 0.5 μm, 1 μm, 5 μm, 10 μm, 15 μm, 20 μm, 25 μm, 30 μm, 35 μm, 40 μm, 45 μm, or 50 μm. It should be noted that the particle size of the light-scattering particles can be set according to factors such as the content of the light-emitting delay material, the product type of the light-emitting component 3, and the application scenario of the light-emitting light-shielding curtain; this embodiment does not impose specific limitations.

[0092] Light-scattering particles include, but are not limited to, at least one of titanium oxide, zirconium oxide, and zinc oxide. Understandably, titanium oxide, zirconium oxide, and zinc oxide have excellent scattering properties, thus converting direct light into soft, diffused light, resulting in good light-blocking effect for the sunshade assembly 300. Furthermore, the use of titanium oxide can generate active oxygen under ultraviolet light to decompose organic pollutants such as dust and oil stains, improving the self-cleaning properties of the sunshade assembly 300.

[0093] It should be noted that the light-emitting component 3 in the first to third embodiments is applicable to the light-emitting light-blocking curtains of the first to fourth embodiments. The structure of the light-functional coating 8 in the fourth embodiment is applicable to the light-emitting light-blocking curtains of the first to third embodiments described above.

[0094] Please refer to the following: Figures 2 to 16 In this embodiment, the material of the light-emitting delay structure 7 further includes a dispersing material. The dispersing material includes at least one of polyester, epoxy polymer, and acrylate polymer. Thus, the light-emitting delay material can be blended, coated, or deposited with the functional layers of the light-emitting component 3, the second adhesive layer 5, or the second fabric 2 to form the light-emitting delay structure 7. Of course, in some embodiments, the dispersing material can be omitted from the material of the light-emitting delay structure 7; that is, the material of the light-emitting delay structure 7 only includes the light-emitting delay material, which is blended in the functional layers of the light-emitting component 3, the second adhesive layer 5, or the second fabric 2.

[0095] In some embodiments, the material of the light-emitting delay structure 7 further includes a dispersing material and at least one multi-color light-emitting material. The multi-color light-emitting material is used to generate multiple colors after being excited by the emitted light. Thus, after the light emitted by the light-emitting component 3 is emitted, the light-emitting delay structure 7 can display multiple patterns in the corresponding display area based on the change in the visible light range of the multi-color light-emitting material or the adjustment of the light-emitting range of the light-emitting component 3, thereby achieving a dynamic display effect, enriching the display effect of the sunshade assembly 300, and improving the visual experience of the driver and passengers.

[0096] The light-emitting component 3 can provide monochromatic light emission; or, the light-emitting component 3 can also provide polychromatic light emission, which is not specifically limited in the embodiments of this application.

[0097] In some embodiments, the light-emitting component 3 is used to provide emitted light of different wavelengths. The multicolor light-emitting material may include materials of different wavelengths. Thus, the different wavelength materials selectively absorb light of specific wavelengths provided by the light-emitting component 3 to excite the generation of different colors of light. The different wavelength materials are, for example, doped with a variety of different light-emitting ions and / or contain a variety of different types of luminescent groups, wherein the light-emitting ions may be, but are not limited to, rare earth ions, such as Eu. 3+ 、Tb3+ Dy 3+ 、Sm 3+ The luminescent group includes, but is not limited to, at least one of organic dye molecules and quantum dots. Multicolor luminescent materials can be one or more types. For example, the same material with different response bands can be used as a multicolor luminescent material; or, different materials with different response bands can be used as multicolor luminescent materials.

[0098] In some other embodiments, the light-emitting component 3 is used to provide emitted light of a single wavelength. The multicolor light-emitting material may also include defect-state / surface-state light-emitting materials, excitation power-dependent light-emitting materials, concentration-effect / aggregation-induced emission conversion materials, etc. For example, defect-state / surface-state light-emitting materials include, but are not limited to, carbon dot materials or silicon quantum dot materials. Thus, under the excitation of emitted light of the same wavelength, multiple light-emitting centers with different energy structures in the multicolor light-emitting material can be excited simultaneously.

[0099] Please refer to the following: Figures 1 to 16 In the light emission path from the electroluminescent layer 321 towards the outside of the vehicle, various components between the glass body 400 and the electroluminescent layer 321 form a combined structure 10. The light transmittance of the combined structure 10 is less than or equal to 10%. Understandably, when some of the light emitted from the electroluminescent layer 321 is transmitted onto the glass body 400, patterns or halos will form on the glass body 400, causing the patterns seen by the driver or passenger inside the vehicle 1000 to be blurred, or allowing people outside the vehicle to see the light inside the vehicle, thus affecting privacy protection. Therefore, this embodiment of the application, based on setting the light transmittance of the combined structure 10 within a suitable range, reduces the light emitted from the electroluminescent layer 321 being transmitted to the outside of the vehicle, preventing people outside the vehicle 1000 from seeing the interior of the vehicle 1000, and improving privacy and security.

[0100] When the light-emitting layer 32 includes an electroluminescent layer 321 and a dielectric layer 322, with the dielectric layer 322 located between the electroluminescent layer 321 and the first conductive layer 31, the dielectric layer 322, the first conductive layer 31, the first adhesive layer 4, the first curtain fabric 1, and the glass body 400 form a combined structure 10. When the light-emitting layer 32 is an electroluminescent layer 321, the first conductive layer 31, the first adhesive layer 4, the first curtain fabric 1, and the glass body 400 form a combined structure 10. When the light-emitting component 3 is fixedly connected to the first curtain fabric 1 by stitching, the dielectric layer 322, the first conductive layer 31, the first curtain fabric 1, and the glass body 400 form a combined structure; or, the first conductive layer 31, the first curtain fabric 1, and the glass body 400 form a combined structure 10; or, the first curtain fabric 1 and the glass body 400 form a combined structure 10. It should be noted that the combined structure can be set according to the specific structure of the components on the path of light emitted from the electroluminescent layer towards the vehicle exterior, and the embodiments of this application do not impose too many specific limitations.

[0101] In this embodiment, the light-emitting delay structure 7 is configured as a light-emitting delay layer. In some embodiments, the light-emitting delay structure 7 includes a supporting substrate and a light-emitting delay coating disposed on the supporting substrate. In other embodiments, the light-emitting delay structure 7 includes a supporting substrate and a light-emitting delay film disposed on the supporting substrate.

[0102] The number of light-emitting delay structures 7 can be set to one or more. For example, in this embodiment, the number of light-emitting delay structures 7 is set to one. The light-emitting delay structure 7 is disposed opposite to the light-emitting layer 32 of the light-emitting component 3, so that most of the emitted light provided by the light-emitting layer 32 can act on the light-emitting delay structure 7, thereby improving the utilization rate of the emitted light by the light-emitting delay structure 7 and saving energy.

[0103] In some embodiments, the number of light-emitting delay structures 7 can be set to multiple, with the orthographic projections of the multiple light-emitting delay structures 7 on the emission direction F of the emitted light being spaced apart or overlapping each other. Therefore, based on the overlapping of the orthographic projections of the multiple light-emitting delay structures 7 on the emission direction F of the emitted light, on the one hand, the different light-emitting delay materials corresponding to the multiple light-emitting delay structures 7 have different afterglow durations or colors, and when they overlap, they produce a gradual and blended light and shadow layer, such as green and red overlapping to form a yellow halo, creating a special visual effect, thereby enriching the display effect of the sunshade assembly 300; on the other hand, the multiple light-emitting delay structures 7 can avoid local dark areas caused by the failure of a single light-emitting delay structure 7, improving the reliability of the display of the sunshade assembly 300. The orthographic projections of the multiple light-emitting delay structures 7 on the emission direction F of the emitted light can completely overlap or partially overlap, and this application embodiment does not specifically limit this. Furthermore, based on the fact that the orthogonal projections of multiple light-emitting delay structures 7 on the emission direction F of the emitted light are spaced apart from each other, on the one hand, the multiple light-emitting delay structures 7 can cooperate to display a preset pattern; or, the multiple light-emitting delay structures 7 can display a preset pattern individually; on the other hand, the spaced arrangement of multiple light-emitting delay structures 7 can block the light mixing path, prevent the light-emitting units of different colors / brightness from color mixing or brightness superposition, and avoid merging into a light fog; furthermore, the physical spacing of multiple light-emitting delay structures 7 provides mechanical support points for the light-emitting light-shielding curtain, reducing stress concentration caused by the continuously arranged light-emitting delay structures 7.

[0104] The areas of the orthogonal projections of the multiple light-emitting delay structures 7 onto the emission direction F of the emitted light can be the same or different. The multiple light-emitting delay structures 7 can be disposed at the same level or different levels of the sunshade assembly 300. It should be noted that "multiple light-emitting delay structures 7 can be disposed at the same level of the sunshade assembly 300" means that the multiple light-emitting delay structures 7 can be disposed at the same level of each functional layer of the sunshade assembly 300. For example, multiple light-emitting delay structures 7 can all be disposed between the conductive base layer 331 and the encapsulation layer 332 of the light-emitting component 3; or, multiple light-emitting delay structures 7 can all be disposed on the side of the second curtain 2 facing away from the second adhesive layer 5, etc. The multiple light-emitting delay structures 7 can be set at different levels of the sunshade assembly 300, which means that the multiple light-emitting delay structures 7 can be set at different levels of each functional layer of the sunshade assembly 300. For example, a part of the multiple light-emitting delay structures 7 can be set between the conductive base layer 331 and the encapsulation layer 332 of the light-emitting component 3, and another part of the multiple light-emitting delay structures 7 can be set on the side of the second curtain 2 facing away from the second adhesive layer 5, etc.

[0105] In this embodiment, the number of light-emitting components 3 can be set in a one-to-one correspondence with the number of light-emitting delay structures 7. Of course, in some embodiments, the number of light-emitting components 3 can be less than the number of light-emitting delay structures 7, that is, multiple light-emitting delay structures 7 share one light-emitting component 3. It should be noted that the number and placement of light-emitting components 3 and the number and placement of light-emitting delay structures 7 can be set according to actual needs, and this application embodiment does not impose specific limitations.

[0106] The light-emitting delay structure 7, when excited by the emitted light provided by the light-emitting component 3, can form a preset pattern. The preset pattern can be customized or set by factory default, and this application embodiment does not impose specific limitations. For example, multiple light-emitting delay structures 7, when excited by the emitted light provided by the light-emitting component 3, can cooperate to form a light-emitting pattern; or, each light-emitting delay structure 7, when excited by the emitted light provided by the corresponding light-emitting component 3, can form a specific light-emitting pattern.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
