In some embodiments, the transparent substrate 10 is a double-glass structure, specifically, the transparent substrate 10 includes a first glass layer, a second glass layer, and a transparent adhesive layer, and the transparent adhesive layer is glued between the first glass layer and the second glass layer. The first glass layer and the second glass layer are both toughened glass, and the transparent adhesive layer can be, but is not limited to, a polyvinyl butyral (polyvinyl butyral, abbreviated as PVB) film or an optical adhesive (Optically CLEAR ADHESIVE, abbreviated as OCA). Of course, the transparent substrate 10 may also be a single-layer glass structure, and may be specifically selected according to the needs.

The light modulation device 20 has a light modulation function, wherein the first transparent substrate layer 21 is arranged on one side of the electrochromic light modulation film 22 facing the transparent substrate 10, the second transparent substrate layer 23 is arranged on one side of the electrochromic light modulation film 22 facing away from the transparent substrate 10, and the first transparent substrate layer 21 and the second transparent substrate layer 23 mainly play roles in supporting and protecting the electrochromic light modulation film 22 and the like, so that the whole of the light modulation device 20 forms a modularized structure, and the light modulation device 20 is convenient to be quickly added on the transparent substrate 10. The electrochromic light adjusting film 22 has electrochromic properties, which means a phenomenon that an optical property of a material changes in color stably and reversibly under the action of an applied electric field, and is expressed as a reversible change in color and/or transparency in appearance. It can be appreciated that dimming can be performed by controlling the color shade of the electrochromic dimming film 22 to achieve the effect of intelligently adjusting the light transmittance.

Compared with the prior art, the rear assembly of the transparent substrate, provided by the application, is connected with the transparent substrate 10 and the light modulation device 20 through the connecting piece 30, so that the light modulation device 20 is added on one side of the transparent substrate 10 to form a light transmission structure with a light modulation function, and the electrochromic light modulation film 22 is clamped through the matching of the first transparent substrate layer 21 and the second transparent substrate layer 23, so that the whole assembly of the light modulation device 20 is modularized, the light modulation device 20 can be quickly added on the transparent substrate 10, the addition is convenient, the light modulation effect is improved by adding the light modulation device 20 on one side of the transparent substrate 10, namely, the effect of intelligently adjusting the light transmittance is achieved by controlling the color depth of the electrochromic light modulation film 22, and in addition, the addition of the light modulation device 20 on the transparent substrate 10 is also beneficial to improving the sound insulation effect of an automobile sky curtain, thereby being beneficial to improving the comfort of noise reduction passengers.

In some embodiments of the present application, referring to fig. 2 and 3, the dimming device 20 has a dimming region 221 and a mounting region 222, the mounting region 222 being disposed around a circumference of the dimming region 221. Specifically, the dimming area 221 is a middle area of the dimming device 20, a portion of the dimming device 20 corresponding to the dimming area 221 is a light-transmitting structure, the mounting area 222 is an edge area of the dimming device 20, and the mounting area 222 is used for wiring and forming a supporting point for connecting the transparent substrate 10, such as electrically connecting the electrode of the electrochromic dimming film 22 and the connection member 30.

The connection member 30 may include one or more of adhesive, snaps, buckles, catches, screws, adhesive tapes, etc., as long as the light modulation device 20 can be assembled with the transparent substrate 10. The adhesive can be transparent adhesive such as PVB and OCA or opaque adhesive. The hasp can be a common hasp, a mushroom hasp and the like. The glue strip may be, but is not limited to, an aluminium sealing strip.

In some embodiments, the connecting member 30 is fixedly connected to the transparent substrate 10 and the light modulation device 20. For example, the connection member 30 may be an adhesive that is adhered between the transparent substrate 10 and the light modulation device 20 to fixedly connect the transparent substrate 10 and the light modulation device 20, that is, to fixedly attach the light modulation device 20 to the transparent substrate 10. Therefore, the connecting piece 30 is fixedly connected to the transparent substrate 10 and the light modulation device 20, so that the reliability of the light modulation device 20 on the transparent substrate 10 is effectively improved.

In some embodiments, the connector 30 is detachably connected to the transparent substrate 10 and the light modulation device 20. For example, the connection member 30 may be a mushroom-shaped snap, a first snap-fit of the mushroom-shaped snap-fit being fixed on a side of the transparent substrate 10 facing the light-adjusting device 20, a second snap-fit of the mushroom-shaped snap-fit being fixed on a side of the light-adjusting device 20 facing the transparent substrate 10, the first snap-fit of the mushroom-shaped snap-fit being snapped together with the second snap-fit to effect attachment of the light-adjusting device 20 to the transparent substrate 10, and the light-adjusting device 20 being detached from the transparent substrate 10 by separating the first snap-fit of the mushroom-shaped snap-fit from the second snap-fit. Therefore, the connector 30 is detachably connected to the transparent substrate 10 and the light modulation device 20, so that the assembly and disassembly are simple and convenient.

In some embodiments of the present application, referring to fig. 4, the rear assembly of the transparent substrate further includes a sealant 31, and the sealant 31 is disposed between the peripheral edges of the transparent substrate 10 and the light modulation device 20 to increase the stability and sealing of the connection between the transparent substrate 10 and the light modulation device 20. Alternatively, the sealant 31 may be, but is not limited to, PVB, ethylene vinyl acetate (ETHYLENE VINY ACETATE, EVA for short), an ionic interlayer (e.g., SENTRY GLAS Plus, SGP for short), or a thermoplastic polyurethane elastomer (Thermoplastic Urethane, TPU for short), etc.

In some embodiments of the present application, referring to fig. 1, the connecting member 30 is disposed at the peripheral edges of the transparent substrate 10 and the light modulation device 20. The light modulator 20, the transparent substrate 10 and the connector 30 together enclose a cavity. By forming the cavity 40 between the light adjusting device 20 and the transparent substrate 10, the cavity 40 can be better insulated, for example, the burning feeling of the head top of the passenger under the sun is reduced, the riding experience of the passenger is improved, and in addition, the interior of the vehicle can have better sound insulation and noise reduction effects.

In some embodiments, referring to fig. 4, the cavity 40 is filled with a medium 50, where the medium 50 may be a light-transmitting medium that helps to cool the transparent substrate 10 and/or the light modulation device 20, or may be a light-transmitting medium that helps to warm the transparent substrate 10 and/or the light modulation device 20. It will be appreciated that by filling the medium 50 within the cavity 40, heating and cooling effects are achieved on the transparent substrate 10 and/or the light modulating device 20. In the embodiment of the present application, the medium 50 is used as a cooling medium, that is, the medium 50 is filled in the cavity 40, so that the medium 50 is used for absorbing heat to cool the vehicle awning, which is beneficial to further improving the heat insulation effect of the vehicle awning.

When the medium 50 is not filled in the cavity 40, the cavity 40 may not need to be completely sealed, and a specific structure of the cavity 40 may not be required, for example, a gap between the light modulation device 20 and the transparent substrate 10 may not be required to be consistent, so that the light modulation device 20 and the transparent substrate 10 may be easily assembled and disassembled.

When the cavity 40 does not need to be completely sealed, a plurality of connecting members 30 may be disposed at intervals to connect the light modulation device 20 and the transparent substrate 10, for example, six connecting members 30 may be disposed at intervals around the circumference of the light modulation region 221 in the mounting region 222, as shown in fig. 2. It is also possible to use two U-shaped connectors 30 disposed opposite to each other in the mounting area 222 and surrounding the outer peripheral side of the dimming area 221, as shown in fig. 3.

When the medium 50 filled in the cavity 40 is not in communication with the outside, the cavity 40 may be a closed cavity. Specifically, a sealing assembly is formed by sandwiching the connection member 30 between the peripheral edge of the transparent substrate 10 and the peripheral edge of the light modulation device 20, so that the cavity 40 forms a closed cavity.

In some embodiments, the medium 50 may be solid or fluid. When the medium 50 filled in the cavity 40 is not in communication with the outside and the medium 50 is solid, the cavity 40 may not need to be completely sealed.

When the medium 50 is filled in the cavity 40 and the medium 50 is fluid, the cavity 40 is a closed cavity, and the cavity 40 needs to be sealed. For example, the connection member 30 may be an adhesive, which is sealed between the transparent substrate 10 and the circumferential edge of the light modulation device 20, as shown in fig. 4. The connector 30 may also be a snap-fit connection between the transparent substrate 10 and the circumferential edge of the dimmer device 20, the sealant 31 being sealed to the side of the snap-fit connection facing away from the cavity 40, as shown in fig. 5. As can be appreciated, when assembling, after the light modulation device 20 is fixed on the transparent substrate 10 by using the buckle, the sealant 31 is then applied to the side of the buckle facing away from the cavity 40, so as to seal between the peripheral edges of the transparent substrate 10 and the light modulation device 20, so as to ensure the sealing performance between the peripheral edges of the transparent substrate 10 and the light modulation device 20.

In some embodiments, referring to fig. 4 and 5, the connecting member 30 or the light modulation device 20 is provided with a medium inlet 33 and a medium outlet 34 which are communicated with the cavity 40, wherein the medium inlet 33 and the medium outlet 34 are both used for connecting an external circulation pipeline, the medium inlet 33 is used for allowing the medium 50 to enter the cavity 40 from the external circulation pipeline, and the medium outlet 34 is used for allowing the medium 50 in the cavity 40 to flow into the external circulation pipeline. For example, when the medium 50 is used as a cooling medium for cooling, the medium 50 absorbs heat in the cavity 40, and then exchanges heat through the external circulation pipeline to dissipate heat of the medium 50, so that the medium 50 in the cavity 40 can continuously absorb heat of the automobile sky curtain, and a good heat insulation effect is achieved.

In some embodiments, when the medium 50 can flow through the cavity 40 and the external circulation line through the medium inlet 33 and the medium outlet 34, and the medium 50 is a refrigerant medium, the medium 50 can be a refrigerant or cold air.

According to the technical scheme, the medium inlet 33 and the medium outlet 34 which are communicated with the cavity 40 are arranged on the connecting piece 30 or the light modulation device 20, before refrigeration, the cavity 40 can be filled with no medium, the medium inlet 33 and the medium outlet 34 are connected to an air conditioning circulation pipeline of an automobile, for example, the medium inlet 33 is connected to an air outlet of the automobile air conditioner through an air pipe, and the medium outlet 34 is connected to an air inlet of the automobile air conditioner through an air pipe, so that cold air of the air conditioner can circulate in the cavity 40, and the effect of reducing the temperature of a rear assembly is achieved.

Besides being directly connected to the air conditioning and refrigerating system of the automobile, the external circulation pipeline may also be provided with a heat exchanger and a circulation pump separately to realize heat exchange of the medium 50.

In some embodiments of the present application, referring to fig. 5, the light modulation device 20 further includes a temperature sensor 35, where the temperature sensor 35 is disposed corresponding to the medium outlet 34, and the temperature sensor 35 is configured to sense a temperature of the medium 50 in the cavity 40.

The medium 50 is exemplified as a gas, and when the temperature sensor 35 detects that the temperature of the medium 50 is greater than a preset temperature, the air conditioning and refrigerating system of the automobile is started to circularly radiate the medium 50, and when the temperature sensor 35 detects that the temperature of the medium 50 is less than or equal to the preset temperature, the air conditioning and refrigerating system of the automobile stops circularly working on the medium 50.

In some embodiments, the connection 30 is filled between the transparent substrate 10 and the dimming device 20. For example, the connection member 30 may be a transparent adhesive, which completely fills in a gap formed between the transparent substrate 10 and the light modulation device 20. Thus, by filling the connection member 30 between the transparent substrate 10 and the light modulation device 20, the stability of attaching the light modulation device 20 to the transparent substrate 10 is effectively improved, and the heat insulation performance is also improved.
