[0046] Unless otherwise specified, the "end surface" described in the present application refers to the surface of the electrochromic device along its thickness direction when the electrochromic device is placed on a horizontal plane.

[0047] In the related art, a first lead electrode and a second lead electrode are respectively arranged on the first conductive substrate layer and the second conductive substrate layer of the electrochromic device, so that the electrochromic device is electrically connected to the positive power line and the negative power line of the external power source through the first lead electrode and the second lead electrode. However, the stability of the electrical connection between the electrochromic device of this structure and the external power source is poor, resulting in a high probability of electrical connection failure between the electrochromic device and the external power source.

[0048] As shown in Figure 1 and Figure 2 The embodiment of the present application provides an electrochromic light modulation diaphragm 100. The electrochromic light modulation diaphragm 100 comprises a first conductive substrate layer 110, an electrochromic light modulation layer 120 and a second conductive substrate layer 130 which are sequentially stacked, and at least two groups of lead electrodes 140, each group of lead electrodes 140 extends outwardly in a direction perpendicular to the end face of the electrochromic light modulation diaphragm 100, and adjacent two groups of lead electrodes 140 are separated from each other.

[0049] Each group of lead electrodes 140 comprises a first lead electrode 141 and a second lead electrode 142, one end of the first lead electrode 141 is electrically connected to the first conductive substrate layer 110, and the other end is used to connect with the first external terminal of the external power source, one end of the second lead electrode 142 is electrically connected to the second conductive substrate layer 130, and the other end is used to connect with the second external terminal of the external power source.

[0050] The electrochromic light modulation diaphragm 100 provided by the embodiment of the present application, the first lead electrode 141 is connected with the first conductive substrate layer 110 and the first external terminal of the external power source respectively, and the second lead electrode 142 is connected with the second conductive substrate layer 130 and the second external terminal of the external power source respectively, so as to realize the electrical connection between the first conductive substrate layer 110 and the second conductive substrate layer 130 and the external power source. The voltage is input to the first conductive substrate layer 110 and the second conductive substrate layer 130 through the external power source, so that the electrochromic light modulation layer 120 responds to the change of the voltage to produce reversible and stable color change, and realizes the light modulation function of the electrochromic light modulation diaphragm 100. Any one of the first lead electrode 141 and the second lead electrode 142 can be positive, and the other one can be negative.

[0051] Meanwhile, by setting the number of the lead-out electrodes 140 to at least two, and extending the at least two groups of the lead-out electrodes 140 outward along a direction perpendicular to the end face of the electrochromic light-shading film 100 and spacing them apart, the electrochromic light-shading film 100 can be electrically connected to the external power source through the at least two groups of the lead-out electrodes 140, so that even if one of the lead-out electrodes 140 fails to be electrically connected, the electrochromic light-shading film 100 can still be stably electrically connected to the external power source through the remaining lead-out electrodes 140, effectively improving the stability of the electrical connection between the electrochromic light-shading film 100 and the external power source, reducing the probability of failure of the electrical connection between the electrochromic light-shading film 100 and the external power source, and ensuring the use stability and reliability of the electrochromic light-shading film 100.

[0052] For example, the first lead-out electrode 141 and the second lead-out electrode 142 can both be flexible circuit boards, the first external terminal can be a positive terminal or a negative terminal, and the second external terminal can be a negative terminal or a positive terminal.

[0053] It should be noted that the first conductive substrate layer 110 includes a first conductive layer and a first substrate layer which are stacked, and the first conductive layer is arranged between the first substrate layer and the electrochromic light-shading layer 120; the second conductive substrate layer 130 includes a second conductive layer and a second substrate layer which are stacked, and the second conductive layer is arranged between the second substrate layer and the electrochromic light-shading layer 120. Specifically, the electrochromic light-shading film 100 includes a first substrate layer, a first conductive layer, an electrochromic light-shading layer 120, a second conductive layer, and a second substrate layer which are sequentially stacked.

[0054] The first substrate layer and the second substrate layer are both transparent substrates, and the "transparent substrate" is an optical-grade transparent material, which can be a flexible substrate material such as Polyethylene Glycol Terephthalate (PET), Polycarbonate (PC), Polyimide (PI), cyclic olefin copolymer, or cellulose triacetate.

[0055] In addition, the first conductive layer and the second conductive layer are both transparent conductive layers, and the material of the "transparent conductive layer" can be any transparent conductive material known to those skilled in the art, such as Indium-Tin Oxide (ITO), Aluminum Zinc Oxide (AZO), Fluorine Doped Tin Oxide (FTO), silver nanowires, graphene, carbon nanotubes, metal mesh, or silver nanoparticles.

[0056] In some embodiments of this application, the edge region of the electrochromic color-changing film 100 is provided with alternating first grooves and second grooves. The number of the first grooves and the second grooves can be one, two or more, and can be specifically set according to the actual situation.

[0057] In addition, the first groove penetrates the first base layer, the first conductive layer and the electrochromic color-changing layer 120, and exposes a portion of the second conductive layer so as to form a first electrode through the exposed portion of the second conductive layer. The first lead-out electrode 141 covers the first electrode so as to be electrically connected to an external power source through the first lead-out electrode 141.

[0058] The second groove penetrates the second base layer, the second conductive layer, and the electrochromic color-changing layer 120, and exposes a portion of the first conductive layer to form a second electrode. The second lead-out electrode 142 covers the second electrode to connect to an external power source through the second lead-out electrode 142, thereby connecting the first conductive layer and the second conductive layer to the external power source respectively.

[0059] like Figure 2 As shown, in one embodiment of this application, at least two sets of lead-out electrodes 140 are spaced apart and disposed on the same side of the edge region of the electrochromic color-changing film 100. According to common knowledge in the art, the electrochromic color-changing film 100 includes a visible area and an edge region surrounding the visible area, the edge region being a non-visible area.

[0060] In this embodiment, by arranging at least two sets of lead-out electrodes 140 at intervals on the same side of the upper edge region of the electrochromic color-changing film 100, all lead-out electrodes 140 are located on the same edge of the electrochromic color-changing film 100, thereby facilitating wiring between the lead-out electrodes 140 and the external terminals of the external power supply to achieve electrical connection.

[0061] It should be noted that the orthographic projection shape of the electrochromic color-changing film 100 on the plane perpendicular to the stacking direction is a polygon, and at least two sets of lead-out electrodes 140 are spaced apart on any one side of the polygon.

[0062] like Figure 2 As shown in the above embodiments of this application, the edge region of the electrochromic color-changing film 100 includes a straight edge region and a curved edge region adjacent to the straight edge region, and at least two sets of lead-out electrodes 140 are located on the straight edge.

[0063] In this embodiment, at least two sets of lead-out electrodes 140 are spaced apart on the straight edge area of ​​the electrochromic color-changing film 100 so that the two sets of lead-out electrodes 140 are led out through the gap between the straight edge edges of two adjacent hollow glass units 2000 and electrically connected to the external terminal of an external power supply.

[0064] Furthermore, the orthographic projection shape of the electrochromic color-changing film 100 on the plane perpendicular to the stacking direction is a fan shape, and at least two sets of lead-out electrodes 140 are located on any straight edge of the fan shape, reducing the difficulty of setting up the two sets of lead-out electrodes 140.

[0065] For example, the spacing between any two adjacent sets of lead electrodes 140 can be between 200-300 mm.

[0066] like Figure 3 As shown, embodiments of this application also provide a laminated glass 1000, including a first substrate 200, a second substrate 300, and the electrochromic color-changing film 100 in the above embodiments.

[0067] The first substrate 200 has a first adhesive layer 210, and the second substrate 300 has a second adhesive layer 310 on the side closest to the first substrate 200. An electrochromic color-changing film 100 is disposed between the first adhesive layer 210 and the second adhesive layer 310, and is bonded to both the first adhesive layer 210 and the second adhesive layer 310. The first adhesive layer 210 and the second adhesive layer 310 cooperate to cover the electrochromic color-changing film 100.

[0068] The laminated glass 1000 provided in the embodiments of this application, by respectively providing a first adhesive layer 210 and a second adhesive layer 310 on a first substrate 200 and a second substrate 300, adheres an electrochromic dimming film 100 between the first adhesive layer 210 and the second adhesive layer 310, and connects the edges of the first adhesive layer 210 and the second adhesive layer 310 to cover the electrochromic dimming film 100. This provides complete sealing protection for the dimming unit, preventing external moisture from contacting the dimming unit and causing it to malfunction, thus affecting its service life. Furthermore, it enhances the connection strength between the dimming unit and the first substrate 200 and the second substrate 300, ensuring the stability and reliability of the dimming unit in use.

[0069] For example, the first substrate 200 and the second substrate 300 can both be made of glass, and the laminated glass 1000 can be applied to vehicle glass.

[0070] like Figure 4 As shown, embodiments of this application also provide an insulated glass 2000, including a first substrate 200 and the electrochromic color-changing film 100 in the above embodiments.

[0071] The first substrate 200 has a first adhesive layer 210, and the electrochromic color-changing film 100 is disposed on the side of the first adhesive layer 210 away from the first substrate 200. A sealing separator 400 is disposed on the first substrate 200 and located on the end face of the electrochromic color-changing film 100. A second substrate 300 is disposed on the side of the sealing separator 400 away from the first substrate 200 and is spaced apart from the electrochromic color-changing film 100.

[0072] The insulating glass 2000 provided in this application has an electrochromic color-changing film 100 securely mounted on a first substrate 200 via a first adhesive layer 210. A sealing spacer 400 is disposed on the first substrate 200 and located on the end face of the electrochromic color-changing film 100, and a second substrate 300 is disposed on the side of the sealing spacer 400 away from the first substrate 200 and spaced apart from the electrochromic color-changing film 100. In this way, the first substrate 200, the sealing spacer 400, and the second substrate 300 can form a hollow cavity for accommodating and sealing the electrochromic color-changing film 100. This provides heat insulation and prevents external moisture from contacting the electrochromic color-changing film 100 inside the hollow cavity, which could cause the electrochromic color-changing film 100 to fail and affect its service life.

[0073] For example, the first substrate 200 and the second substrate 300 can both be formed from one or more of glass materials, ceramic materials, glass-ceramic materials, and polymer materials, and the insulated glass 2000 can be applied to architectural glass.

[0074] The sealing isolation element 400 may include a first sealing layer, an isolation layer, and a second sealing layer stacked sequentially. The isolation layer may be a frame made of one or any combination of metal, polymer, glass, ceramic, or glass-ceramic materials, preferably a metal frame, and the frame is filled with a desiccant-like material. Both the first and second sealing layers may be butyl rubber, silicone rubber, silicone rubber, polysulfide rubber, or other materials with sealing functions. In some embodiments, the sealing isolation element 400 may also be integrally molded from 4SG material.

[0075] like Figure 4 As shown in the above embodiments of this application, a second adhesive layer 310 is provided on the side of the electrochromic color-changing film 100 away from the first adhesive layer 210. The edges of the first adhesive layer 210 and the second adhesive layer 310 are connected to each other and cooperate to cover the electrochromic color-changing film 100.

[0076] In the embodiment, the second adhesive layer 310 is arranged on the side of the electrochromic light-adjusting diaphragm 100 away from the first adhesive layer 210, and the electrochromic light-adjusting diaphragm 100 is wrapped by the first adhesive layer 210 and the second adhesive layer 310. In this way, on the one hand, the electrochromic light-adjusting diaphragm 100 is completely sealed and protected, and the contact between the electrochromic light-adjusting diaphragm 100 and external water vapor is further prevented, so that the electrochromic light-adjusting diaphragm 100 is not invalidated, and the service life of the electrochromic light-adjusting diaphragm 100 is affected. On the other hand, the connection strength between the electrochromic light-adjusting diaphragm 100 and the first substrate 200 is further improved, and the use stability and reliability of the electrochromic light-adjusting diaphragm 100 are further ensured.

[0077] As shown in Figure 5 The embodiment of the present application also provides a hollow glass assembly 10000, which comprises a plurality of hollow glasses 2000 as in the above embodiments. The plurality of hollow glasses 2000 are spliced with each other to form a predetermined pattern.

[0078] For example, in the embodiment, the hollow glass 2000 has a fan-shaped shape in the orthographic projection on the plane perpendicular to the axis of the hollow glass assembly 10000, and the plurality of fan-shaped hollow glasses 2000 are spliced to form the hollow glass assembly 10000 with a circular cross section. The plurality of hollow glasses 2000 are spliced in sequence around the axis of the hollow glass assembly 10000 and in sequence away from the axis of the hollow glass assembly 10000. It should be noted that the axis of the hollow glass assembly 10000 is a straight line passing through the center of the circle and perpendicular to the plane in which the hollow glass assembly 10000 is located. In this way, the hollow glass assembly 10000 can be applied to a dome-shaped building glass, so that on the one hand, the dome-shaped building glass has a light-adjusting function to achieve sun protection, and on the other hand, the dome-shaped building glass has a variable color-changing effect, effectively improving the aesthetic appearance.

[0079] It should be noted that the hollow glass assembly 10000 further comprises a bus, and the electrochromic light-adjusting diaphragm 100 of each hollow glass 2000 is electrically connected to the bus through the two groups of lead electrodes 140, so as to control the work of different electrochromic light-adjusting diaphragms 100 through the bus. In addition, the plurality of hollow glass assemblies 10000 can be spliced with each other to form other predetermined patterns according to needs, which will not be illustrated one by one here.
