[0046] As Figure 1As shown, the embodiment of the present application provides a hollow glass 100. The hollow glass 100 comprises a first hollow structure 110, at least one second hollow structure 120 and a light adjusting unit 130.

[0047] The first hollow structure 110 has a first hollow cavity 111, and the second hollow structure 120 is arranged on one side or opposite sides of the first hollow structure 110, and the second hollow structure 120 has a second hollow cavity 121. The light adjusting unit 130 is arranged in the first hollow cavity 111.

[0048] The embodiment of the present application provides a hollow glass 100. By arranging the second hollow structure 120 on one side or opposite sides of the first hollow structure 110 and arranging the light adjusting unit 130 in the first hollow cavity 111, on the one hand, the hollow glass 100 has at least two hollow cavities, thereby increasing the number of hollow cavities, and further improving the heat insulation performance of the hollow glass 100, on the other hand, by arranging the light adjusting unit 130 to control the color change of the light adjusting unit 130, the color of the hollow glass 100 can change from transparent to opaque, thereby further blocking the entry of light, so as to better realize the sun protection and heat insulation performance of the hollow glass 100. Illustratively, the light adjusting unit 130 can comprise a first substrate layer, a first conductive layer, an electrochromic medium layer, a second conductive layer and a second substrate layer arranged in sequence.

[0049] It should be noted that in the above-mentioned embodiments of the present application, 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.

[0050] 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 nanowire, graphene, carbon nanotube, metal mesh or silver nanoparticles.

[0051] In some embodiments of the present application, the edge area of the light adjusting unit 130 is provided with first grooves and second grooves arranged alternately, the number of the first grooves and the second grooves can be one, two or any number of two or more, which can be set according to actual conditions.

[0052] In addition, the first grooves penetrate the first base layer, the first conductive layer and the light adjusting layer, and expose part of the second conductive layer, so as to form a first electrode through the exposed part of the second conductive layer, and to be electrically connected with an external power supply through the first electrode.

[0053] The second grooves penetrate the second base layer, the second conductive layer and the light adjusting layer, and expose part of the first conductive layer, so as to form a second electrode, and to be connected with the external power supply through the second electrode, thereby connecting the first conductive layer and the second conductive layer with the external power supply respectively.

[0054] As shown in the drawings, Figure 1 In one embodiment of the present application, at least one second hollow structure 120 is arranged on the side close to the heat source or the light source, and the second hollow structure 120 is used to reduce the heat entering the first hollow structure 110.

[0055] In the present embodiment, the number of the second hollow structure 120 can be one or more, by arranging the second hollow structure 120 on the side close to the heat source or the light source of the first hollow structure 110, and arranging the light adjusting unit 130 in the first hollow cavity 111, so that the light adjusting unit 130 is located on the side of the hollow glass 100 away from the heat source or the light source, thereby enabling most of the heat entering the hollow glass 100 from the heat source or the light source to be eliminated in turn by the second hollow cavity 121 and the first hollow cavity 111, and the remaining small part of the heat to be eliminated by the light adjusting unit 130, further reducing the energy consumption of the light adjusting unit 130. For example, the heat source or the light source can be one of artificial heat source, artificial light source, natural heat source and natural light source, such as sun, lighting lamp, heater, etc. In the present embodiment, the second hollow cavity 121 close to the heat source or the light source can effectively isolate part of the heat and light, so that the heat and light entering the first hollow cavity 111 are less, thereby avoiding the light adjusting unit 130 being too close to the heat source or the light source, so as to prolong the service life of the light adjusting unit 130 in the first hollow structure 110.

[0056] As shown in the drawings, Figure 1In the above embodiments of the present application, the first hollow structure 110 includes a first substrate 112, a first sealing spacer 113 and a second substrate 114. The first sealing spacer 113 is arranged on the first substrate 112 and located at the edge of the first substrate 112. The second substrate 114 is arranged on the side of the first sealing spacer 113 away from the first substrate 112, and the first substrate 112, the first sealing spacer 113 and the second substrate 114 form the first hollow cavity 111. The second hollow structure 120 is arranged on the side of the second substrate 114 away from the first substrate 112.

[0057] In the present embodiment, by arranging the first sealing spacer 113 on the first substrate 112 and located at the edge of the first substrate 112, and arranging the second substrate 114 on the side of the first sealing spacer 113 away from the first substrate 112, a closed first hollow cavity 111 is defined. On the one hand, this can play a heat insulation effect, and on the other hand, it can also prevent the water vapor in the outside from contacting the light adjusting unit 130 in the first hollow cavity 111, thereby preventing the light adjusting unit 130 from being invalid, and affecting the service life of the light adjusting unit 130.

[0058] At the same time, by arranging the second hollow structure 120 on the side of the second substrate 114 away from the first substrate 112, most of the heat entering the hollow glass 100 from the outside can be eliminated by the second hollow cavity 121 and the first hollow cavity 111 in turn, and the remaining small part of the heat can be eliminated by the light adjusting unit 130, thereby effectively reducing the energy consumption of the light adjusting unit 130.

[0059] For example, the first substrate 112 and the second substrate 114 can be formed by one or a combination of glass material, ceramic material, glass-ceramic material and high polymer polymeric material. The first hollow cavity 111 can be filled with one or any combination of air, nitrogen, argon, helium, neon, krypton, xenon and carbon dioxide, or can be in a vacuum state.

[0060] The first sealing spacer 113 can include a first sealing layer, a first isolation layer and a second sealing layer stacked in turn. The first isolation layer can be a frame made of one or any combination of metal material, polymeric material, glass material, ceramic material and glass-ceramic material, and is preferably a frame made of metal material. The frame is filled with desiccant material. The first sealing layer and the second sealing layer can be butyl rubber, silicone rubber, silicone rubber, polysulfide rubber or other materials with sealing function. In other embodiments, the first sealing spacer 113 can also be integrally formed by 4SG material.

[0061] As Figure 1As shown, in the above embodiments of this application, the dimming unit 130 is disposed on the first substrate 112.

[0062] In this embodiment, by placing the dimming unit 130 on the first substrate 112, the dimming unit 130 is stably placed in the first hollow cavity 111 and its position is fixed, thereby ensuring the stability and reliability of the dimming unit 130 in use.

[0063] In other embodiments, the dimming unit 130 is disposed on the side of the second substrate 114 near the first substrate 112. Thus, by disposing the dimming unit 130 on the side of the second substrate 114 near the first substrate 112, the dimming unit 130 is stably disposed within the first hollow cavity 111 and its position is kept fixed, thereby ensuring the stability and reliability of the dimming unit 130 in use.

[0064] like Figure 1 As shown in the above embodiments of this application, the insulating glass 100 further includes a first adhesive layer 140, and the dimming unit 130 is bonded to the first substrate 112 through the first adhesive layer 140, or the dimming unit 130 is bonded to the second substrate 114 through the first adhesive layer 140.

[0065] In this embodiment, the dimming unit 130 is bonded to the first substrate 112 or the second substrate 114 through the first adhesive layer 140, so that the dimming unit 130 is stably disposed on the first substrate 112 or the second substrate 114 under the adhesive action of the first adhesive layer 140, thereby keeping the dimming unit 130 in a fixed position within the first hollow cavity 111, thus ensuring the stability and reliability of the dimming unit 130 in use.

[0066] like Figure 1 As shown in the above embodiments of this application, the insulating glass 100 further includes a second adhesive layer 150, which is disposed on the side of the dimming unit 130 away from the first adhesive layer 140, and the circumferential edges of the first adhesive layer 140 and the second adhesive layer 150 are connected to cover the dimming unit 130.

[0067] In this embodiment, by providing a second adhesive layer 150 on the side of the dimming unit 130 away from the first adhesive layer 140, and connecting the circumferential edges of the first adhesive layer 140 and the second adhesive layer 150 to cover the dimming unit 130, a complete sealed protection for the dimming unit 130 can be formed, further preventing external moisture from contacting the dimming unit 130 and causing it to fail, thus affecting the service life of the dimming unit 130.

[0068] like Figure 1As shown in the above embodiments of this application, the insulating glass 100 further includes a protective layer 160, which is disposed on the side of the second adhesive layer 150 away from the dimming unit 130.

[0069] In this embodiment, by providing a protective layer 160 on the side of the second adhesive layer 150 away from the dimming unit 130, the second adhesive layer 150, the dimming unit 130 and the first adhesive layer 140 are protected as a whole, which further ensures the stability and reliability of the dimming unit 130.

[0070] For example, the protective layer 160 can be made of at least one of PET (Polyethylene Terephthalate), PE (Polyethylene), and OPP (Oriented Polypropylene).

[0071] like Figure 2 As shown in the above embodiments of this application, the second hollow structure 120 includes a second sealing isolation member 122 and a third substrate 123. The second sealing isolation member 122 is disposed on the side of the second substrate 114 away from the first substrate 112 and is located at the edge of the second substrate 114. The third substrate 123 is disposed on the side of the second sealing isolation member 122 away from the second substrate 114. The second substrate 114, the second sealing isolation member 122, and the third substrate 123 form the second hollow cavity 121.

[0072] In this embodiment, by disposing the second sealing isolation member 122 on the second substrate 114 and located at the edge of the second substrate 114, and disposing the third substrate 123 on the side of the second sealing isolation member 122 away from the second substrate 114, a sealed second hollow cavity 121 is defined. Thus, under the heat insulation effect of the second hollow cavity 121, heat entering the first hollow cavity 111 can be effectively reduced, which is beneficial to reducing the energy consumption of the dimming unit 130 in the first hollow cavity 111.

[0073] For example, the third substrate 123 may be formed of one or more of glass materials, ceramic materials, glass-ceramic materials, and polymer materials. The second hollow cavity 121 may be filled with one or more of air, nitrogen, argon, helium, neon, krypton, xenon, and carbon dioxide, and the second hollow cavity 121 may also be evacuated to a vacuum state.

[0074] The second sealing element 122 may include a third sealing layer, a second isolation layer, and a fourth sealing layer stacked sequentially. The second 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. The third and fourth sealing layers may both be butyl rubber, silicone rubber, silicone rubber, polysulfide rubber, or other materials with sealing functions. In some embodiments, the second sealing element 122 may also be integrally molded from 4SG material.

[0075] In the above embodiments of this application, the insulating glass 100 further includes a functional film layer, which is disposed on the side of the third substrate 123 near the second substrate 114, or the functional film layer is disposed on the side of the second substrate 114 near the third substrate 123.

[0076] In this embodiment, a functional film layer is provided on the side of the third substrate 123 near the second substrate 114 or on the side of the second substrate 114 near the third substrate 123. Under the action of the functional film layer, a portion of the heat entering the insulating glass 100 from the outside is reflected back to the outside. This helps to reduce the energy consumption of the dimming unit 130 and also prevents the dimming unit 130 from being directly irradiated by strong external light, which would affect the service life of the dimming unit 130.

[0077] For example, the functional film can be an infrared reflective layer or other types of optical modulation film. The choice of functional film can be determined according to the actual situation.

[0078] like Figure 1 As shown in the above embodiments of this application, the insulating glass 100 further includes a fourth substrate 170 and a third adhesive layer 180. The third adhesive layer 180 is disposed on the side of the first substrate 112 away from the second substrate 114, and the fourth substrate 170 is disposed on the side of the third adhesive layer 180 away from the first substrate 112.

[0079] In this embodiment, by providing a third adhesive layer 180 on the side of the first substrate 112 away from the second substrate 114, and providing a fourth substrate 170 on the side of the third adhesive layer 180 away from the first substrate 112, the fourth substrate 170 can be stably disposed on the side of the first substrate 112 away from the second substrate 114 through the third adhesive layer 180, thereby making the insulating glass 100 have four substrates, effectively improving the overall structural strength of the insulating glass 100.

[0080] For example, the fourth substrate 170 may be formed of one or more combinations of glass materials, ceramic materials, glass-ceramic materials, and polymer materials.

[0081] like ​ As shown in the above embodiments of this application, the insulating glass 100 further includes an outgoing electrode 190, one end of which is electrically connected to the dimming unit 130, and the other end of which extends through the first sealing isolation member 113 to the outside of the insulating glass 100.

[0082] In this embodiment, by electrically connecting one end of the lead-out electrode 190 to the dimming unit 130 and extending the other end of the lead-out electrode 190 through the first sealing isolation member 113 to the outside of the insulating glass 100, the dimming unit 130 is electrically connected to an external power source through the lead-out electrode 190, thereby realizing the power supply and dimming functions of the dimming unit 130.

[0083] For example, the lead electrode 190 can be a flexible circuit board.
