Description

Technical Field

[0001] The present invention relates to the technical field of optical glass, and in particular to a dimming unit and insulating glass. Background Art

[0002] Insulating glass is increasingly used in modern buildings and transportation due to its high energy-saving effect, good noise reduction and insulation function, small weight and good lighting effect, and plays an increasingly important role in improving living comfort and reducing building energy consumption.

[0003] With the rapid development of electrochromic technology, electrochromic devices are gradually being applied to a growing number of fields. This is particularly true in the field of dimming glass. Compared to traditional glass, electrochromic dimming glass offers unparalleled advantages in energy saving, sun shading, and comfort. Therefore, electrochromic dimming glass has broad application prospects in architecture, automobiles, and consumer electronics. Insulating glass using electrochromic technology, based on existing insulating glass, achieves autonomous transmittance adjustment with very low power consumption. This can be combined with light sensors, temperature sensors, or other devices for automatic or manual control, and has broad application prospects in the future.

[0004] However, the electrochromic devices used in existing insulating glass (IG) are susceptible to changes in moisture, oxygen, temperature, and humidity in the air, significantly impacting the lifespan and performance stability of the dimming unit. Furthermore, the manufacturing process for existing IG is complex, and the electrochromic device, a core component of IG, is highly susceptible to environmental influences. This makes storage of semi-finished IG difficult, resulting in low production yields. Furthermore, the complex manufacturing process significantly impacts the mass production of IG.

[0035] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clear, the technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features, and are used to distinguish and describe features, without distinction of order or importance. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0039] Reference below Figure 1-Figure 3 The specific structure of the dimming unit according to the embodiment of the present invention is described.

[0040] like Figure 1-Figure 2 As shown, the dimming unit of the present invention includes a dimming layer 1, an encapsulation layer 2, a first panel 3, a second panel 4 and a power supply structure 5. The encapsulation layer 2 is coated on the outside of the dimming layer 1 to encapsulate the dimming layer 1. The first panel 3 and the second panel 4 are respectively connected to the two sides of the encapsulation layer 2. The power supply structure 5 is connected to the dimming layer 1, and the power supply structure is electrically connected to the dimming layer 1.

[0041] It can be understood that in this embodiment, since the dimming layer 1 is encapsulated in the encapsulation layer 2 and the encapsulation layer 2 is sandwiched between the first panel 3 and the second panel 4, the encapsulation layer 2 is slightly wider than the dimming layer 1, so that the edges of the encapsulation layer 2 are bonded to each other, and the dimming layer 1 is completely covered in the encapsulation layer 2. This greatly improves the bonding stability of the dimming layer 1 between the first panel 3 and the second panel 4, and the encapsulation layer 2 can serve as the first protective layer of the dimming layer 1, and the first panel 3 and the second panel 4 can serve as the second protective layer of the dimming layer 1. This maximizes the protection of the encapsulation layer 2, thereby ensuring the strength of the entire dimming unit, which is beneficial to the preservation of the dimming unit and avoids damage to the dimming layer 1 during transportation and installation.

[0042] In addition, during the processing of the dimming unit, air is easily entrained when the dimming layer 1 is encapsulated in the encapsulation layer 2. By adding a first panel 3 on the encapsulation layer 2, the dimming layer 1 can be encapsulated in the encapsulation layer 2 through pressurization or vacuum processes without damaging the dimming layer 1, thereby better ensuring the dimming effect of the dimming unit.

[0043] In this embodiment, the first panel 3 can be formed from various glass materials, ceramic materials, glass-ceramic materials, polymer materials, or combinations thereof, and the upper surface of the first panel 3 can have a coating layer (such as a low-emissivity coating layer or other specific coating layer). The coating layer thickness ranges from 0 nm to 500 μm, preferably from 100 nm to 50 μm. The thickness of the first panel 3 ranges from 0.1 mm to 100 mm, preferably from 1.1 mm to 10 mm. The second panel 4 can be formed from any one or a combination of glass materials, ceramic materials, glass-ceramic materials, and polymer materials. The thickness of the second panel 4 ranges from 0.1 mm to 100 mm, preferably from 1.1 mm to 30 mm. The dimming unit manufactured using the first and second panels 3 and 4 of the above-mentioned preferred thicknesses has good structural strength. The first and second panels 3 and 4 can withstand large external forces, thereby better improving the strength of the entire dimming unit and reducing the chance of damage to the dimming unit. In actual use, the thicknesses of the first and second panels 3 and 4 can be the same or different. Moreover, the second panel 4 is thicker, which is beneficial to improving the overall structural strength, while the first panel 3 is slightly thinner without affecting the function and its own strength, which is beneficial to the lightweighting of the overall dimmable insulating glass unit. In addition, when packaging the dimming unit, the process adopted in this embodiment can ensure that the temperature difference between the first panel 3 and the second panel 4 does not exceed 10°C, ensuring the structural strength of the dimming unit. In actual use, the sizes of the first panel 3 and the second panel 4 can be the same or different. Specifically, the edge of the first panel 3 is regularly or irregularly indented by a certain size compared to the second panel 4, and the edge indentation size ranges from 0.5mm to 500mm, and the preferred range is 5mm to 100mm.

[0044] Of course, in actual use, the first panel 3 and the second panel 4 can be made of any suitable material according to actual needs, and the size and thickness of the first panel 3 and the second panel 4 can be selected according to actual needs and are not limited to the above limitations.

[0045] In this embodiment, the encapsulation layer 2 is formed of polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), thermoplastic polyurethane (TPU), optically clear adhesive (OCA), ionomer, ionic plastic, optically clear resin (OCR), environmentally friendly latent curing agent (LCA), or a combination thereof, which has a certain degree of adhesion. The thickness of a single layer of the encapsulation layer 2 ranges from 0 to 30 mm, preferably from 0.1 to 3 mm. The thickness of the encapsulation layer 2 on both sides of the dimming layer 1 can be the same or different. Of course, in actual use, the material and thickness of the encapsulation layer 2 can be arbitrarily selected according to actual conditions and are not limited to the above limitations.

[0046] In this embodiment, the dimming layer 1 can be a dimming layer made of one or more flexible or rigid materials. Specifically, it can be a type of dimming layer 1 such as SPD (suspended particle dispersed), PDLC (polymer dispersed liquid crystal), LC (liquid crystal), or EC (electrochromic). The thickness of the dimming layer 1 is within a protective range of 50 μm to 5 mm. In actual use, the type and thickness of the dimming layer 1 can be arbitrarily selected and are not limited to the above.

[0047] In this embodiment, the power supply structure 5 can be a lead wire from the dimming layer 1 to connect the dimming layer 1 to an external power source. It can be made of a flexible printed circuit board, rolled copper foil / aluminum foil, electrolytic copper foil / aluminum foil, etc., and can be made of aluminum, copper, silver, tin, or other conductive metals, non-metallic semiconductor conductive materials or their coatings, or other conductive metal oxides, or a combination thereof. The power supply structure 5 can also be directly formed as a power supply with a control module to directly provide electrical conductivity to the dimming layer 1.

[0048] The dimming unit of the embodiment of the present invention can encapsulate the dimming layer 1 within the encapsulation layer 2 and attach the first panel 3 and the second panel 4 to either side of the encapsulation layer 2, thereby minimizing the impact of various environmental uncertainties on the dimming layer 1, thereby ensuring stable performance of the dimming element and extending the service life of the dimming element. In addition, the multi-layered structure of the encapsulation layer 2, the first panel 3, and the second panel 4 enhances the structural strength of the entire dimming unit, facilitates transportation of the dimming unit, and prevents damage to the dimming unit during transportation.

[0049] In some embodiments, as Figure 2 As shown, the dimming unit also includes a dimming seal 6. The material of the dimming seal 6 can be silicone glue, silicone rubber, butyl rubber, polysulfide rubber, or other materials with sealing functions. Of course, the specific type of the dimming seal 6 can be selected according to actual needs and is not limited to the above. The dimming seal 6 is sandwiched between the first panel 3 and the second panel 4 and is sleeved on the outside of the encapsulation layer 2. It can be understood that the addition of the dimming seal 6 can improve the sealing performance of the dimming layer 1, thereby better reducing the impact of the external environment on the dimming layer 1.

[0050] In some embodiments, as Figure 3 As shown, the dimming layer 1 is a single dimming element; alternatively, the dimming layer 1 includes multiple dimming elements connected together. Consequently, in actual use, different areas of the dimming layer 1 have different dimming properties, allowing the structure of the dimming layer 1 to be designed as a multi-layered structure based on actual needs. This effectively meets various dimming requirements in actual production processes and expands the applicability of the entire dimming functional element.

[0051] In some embodiments, at least one of the first panel 3 and the second panel 4 is a curved panel, or at least one of the first panel 3 and the second panel 4 is a flat panel. This can expand the application scenarios and usage range of the dimming unit, thereby better meeting usage needs.

[0052] Reference below Figure 1-Figure 2 The specific structures of the dimming units according to two specific embodiments of the present invention are described.

[0053] Example 1:

[0054] like Figure 1 As shown, the dimming unit of this embodiment includes a dimming layer 1, an encapsulation layer 2, a first panel 3, a second panel 4, and a power supply structure 5. The encapsulation layer 2 is coated on the outside of the dimming layer 1 to encapsulate the dimming layer 1. The first panel 3 and the second panel 4 are respectively connected to the two sides of the encapsulation layer 2. The power supply structure 5 is connected to the dimming layer 1 and is used to connect the dimming layer 1 to an external power source. The dimming layer 1, encapsulation layer 2, first panel 3, and second panel 4 are all flat panels.

[0055] The process flow for preparing the dimming unit of this embodiment is as follows:

[0056] Step 1: Connect the power supply structure 5 to the dimming layer 1 to form a conductive path connecting the positive and negative electrodes. The dimming layer 1 and the power supply structure 5 form a whole.

[0057] Step 2: Place the second panel 4, a packaging sheet, the dimming layer 1, another packaging sheet, and the first panel 3 in accordance with Figure 1As shown, a stacked structure is formed, and the power supply structure 5 is located between two packaging sheets. The device can be packaged and formed by a lamination process (such as: vacuum degree: -70kpa to -100kpa; temperature: 100℃ to 150℃; pressure: 0.03Mpa-0.1Mpa; holding time 5min-60min, the specific process is determined by the material and thickness of the packaging sheet, the material and thickness of the first panel 3, the second panel 4, the material, thickness and tolerance of the dimming layer 1), high temperature and high pressure in an autoclave under a vacuum environment (vacuum degree: -70kpa to -100kpa, temperature: 100 to 140℃, pressure: 0.4Mpa-1.5Mpa, holding time: 15min-300min; the specific process is determined by the material and thickness of the packaging sheet, the material and thickness of the first panel 3, the second panel 4, the material, thickness and tolerance of the dimming layer 1) or other processing methods.

[0058] Example 2:

[0059] like Figure 2 As shown, the dimming unit of this embodiment includes a dimming layer 1, an encapsulation layer 2, a first panel 3, a second panel 4, a power supply structure 5, and a dimming sealing layer. The encapsulation layer 2 is coated on the outside of the dimming layer 1 to encapsulate the dimming layer 1. The first panel 3 and the second panel 4 are respectively connected to the two sides of the encapsulation layer 2. The power supply structure 5 is connected to the dimming layer 1 and is used to connect the dimming layer 1 to an external power source. The dimming seal 6 is sandwiched between the first panel 3 and the second panel 4 and the dimming seal 6 is sleeved on the outside of the encapsulation layer 2. The dimming layer 1, the encapsulation layer 2, the first panel 3, the second panel 4, and the dimming seal 6 are all flat panels.

[0060] It should be noted that in Examples 1 and 2, the dimming layer 1, encapsulation layer 2, first panel 3, and second panel 4 can be square, circular, elliptical, polygonal, or any other planar shape and any of the shapes after holes are cut. One or more of the dimming layer 1, encapsulation layer 2, first panel 3, and second panel 4 can also be curved panels. The dimming layer 1 can be a complete dimming element or a spliced ​​structure of multiple dimming elements.

[0061] Reference below Figures 4-10 The specific structure of the insulating glass according to the embodiment of the present invention is described.

[0062] like Figures 4-10 As shown, the insulating glass of the present invention includes the dimming unit described above, a third panel 8, and a first sealant 9. The third panel 8 is spaced apart from the dimming unit. One end of the first sealant 9 abuts against the third panel 8, while the other end abuts against the dimming unit. A first hollow cavity 10 is defined between the third panel 8, the first sealant 9, and the second panel 4. The first panel 3 and the dimming layer 1 are located within the first hollow cavity 10.

[0063] It is understood that in this embodiment, the dimming unit is placed in the hollow structure, minimizing the impact of various environmental uncertainties on the dimming layer 1, thereby ensuring the stable performance of the dimming layer 1 and extending the service life of the dimming layer 1. At the same time, during the manufacturing process, since the dimming unit is a pre-fabricated semi-finished product, the production cycle of insulating glass is greatly reduced, production efficiency is improved, and large-scale production of insulating glass is more facilitated.

[0064] In this embodiment, the first hollow cavity 10 can be filled with one or more of air, nitrogen, argon, helium, neon, krypton, xenon, and carbon dioxide. The first hollow cavity 10 can also be drawn into a hollow state. The thickness of the first hollow cavity 10 ranges from 0.1 mm to 500 mm, and the preferred range is from 1 mm to 100 mm. Within a certain range, the greater the thickness of the first hollow cavity 10, the better the thermal insulation effect. The inflation state, gas type, and thickness of the first hollow cavity 10 can be selected according to actual needs and are not limited to the above limitations. In addition, the first sealing member 9 has the function of sealing, isolating water vapor and oxygen in the air from entering the first hollow cavity 10, and preventing the gas in the first hollow cavity 10 from escaping, thereby better improving the sealing of the insulating glass and reducing the impact of the external environment on the dimming layer 1. In this embodiment, the first sealing member 9 is silicone glue, silicone rubber, butyl rubber, polysulfide rubber, or other materials with sealing functions or glass rings. Of course, the specific type of the first sealing member 9 can be selected according to actual needs and is not limited to the above definition.

[0065] In this embodiment, the third panel 8 can be formed of a glass material, a ceramic material, a glass-ceramic material, a polymer material, or a combination thereof. The lower surface of the third panel 8 can have a coating layer (such as a low-emissivity coating or other specific coating). The coating layer has a thickness ranging from 0 nm to 100 μm, preferably from 100 nm to 50 μm. The thickness of the third panel 8 ranges from 0 mm to 100 mm, preferably from 0.5 mm to 15 mm. Of course, in actual use, the third panel 8 can be made of any suitable material according to actual needs. The size and thickness of the third panel 8 can be selected based on actual needs and are not limited to the above.

[0066] In some embodiments, the insulating glass further includes a first spacer 11 and a first spacer 12. There are two first spacers 12. The first spacer 11 is located on the inner side of the first sealing member 9. One of the first spacers 12 is sandwiched between the third panel 8 and the first spacer 11, and the other first spacer 12 is sandwiched between the second panel 4 and the first spacer 11; or one of the first spacers 12 is sandwiched between the third panel 8 and the first spacer 11, and the other first spacer 12 is sandwiched between the first panel 3 and the first spacer 11. It can be understood that the provision of the first spacer 11 and the first spacer 12 can further improve the sealing of the first hollow cavity 10, further prevent external air from entering the first hollow cavity 10 and prevent the occurrence of gas overflow from the first hollow cavity 10, thereby better ensuring the reliability of the dimming layer 1.

[0067] In this embodiment, the material of the first spacer 11 can be one of metal materials, polymer materials, glass materials, ceramic materials, glass-ceramic materials, or a combination of any of them. The interior of the first spacer 11 can be filled with desiccant materials, which help to absorb moisture from the first hollow cavity 10 and prevent water vapor from condensing on the surface of the first panel 3 and / or the third panel 8, thereby avoiding the occurrence of condensation on the surface of the hollow glass. The single-side width of the first spacer 11 ranges from 0.5mm to 500mm, and the preferred single-side width range is 3mm to 20mm. The thickness of the first spacer 11 ranges from 0.5mm to 500mm, and the preferred thickness range is 3mm to 50mm. Of course, in this embodiment, the material, internal filling, single-side width and thickness of the first spacer 11 can be selected according to actual needs and are not limited to the above-mentioned limitations.

[0068] In this embodiment, the material of the first isolating member 12 can be silicone glue, silicone rubber, butyl rubber, polysulfide rubber, or other materials with sealing functions. Of course, the specific type of the first isolating member 12 can be selected according to actual needs and is not limited to the above limitations. The thickness of the first isolating member 12 ranges from 50 μm to 50 mm, and the preferred range is from 0.1 mm to 10 mm. Of course, the material, single-side width, and thickness of the first isolating member 12 can be selected according to actual needs and are not limited to the above limitations.

[0069] In some embodiments, when both the first panel 3 and the second panel 4 are curved, the third panel 8 can be either a curved panel or a flat panel; or when both the first panel 3 and the second panel 4 are flat panels, the third panel 8 can be either a curved panel or a flat panel; and when one of the first panel 3 and the second panel 4 is a flat panel and the other is curved, the third panel 8 can be either a curved panel or a flat panel. Thus, insulating glass can be applied to more occasions, thereby expanding the scope of application of insulating glass.

[0070] In some embodiments, the insulating glass further includes an auxiliary functional layer 13, which is bonded to at least one of the first panel 3, the second panel 4, and the third panel 8. It is understood that the auxiliary functional layer 13 can be a plating or coating (such as a low-emissivity coating or other specific metal element, metal oxide, inorganic coating, organic coating, or other coating or coating, either alone or in combination, with the thickness of the plating or coating ranging from 0 nm to 5 mm, preferably ranging from 100 nm to 2 mm). It can also be an auxiliary layer such as a paint layer, a specific pattern layer, a frosted layer, a film layer, a waterproof and hydrophobic layer, etc. Thus, the addition of the auxiliary functional layer 13 can enable the insulating glass to have other functions such as reducing radiation, displaying patterns, and providing thermal insulation, thereby enabling the insulating glass of this embodiment to better meet practical needs.

[0071] In some embodiments, at least one of the first panel 3, the second panel 4, and the third panel 8 is a multi-layer panel structure; or the first panel 3, the second panel 4, and the third panel 8 are all single-layer panel structures. It is understood that in actual use, certain special situations may require a structurally reinforced insulating glass structure. In this case, at least one of the first panel 3, the second panel 4, and the third panel 8 may be a laminated glass panel, where the laminate may be a polyvinyl butyral (PVB) with a certain degree of adhesion, ethylene vinyl acetate (EVA), thermoplastic polyurethane (TPU), optically clear adhesive (OCA), ionomer, ionic plastic, optically clear resin (OCR), environmentally friendly latent curing agent (LCA), or a combination thereof. The thickness of a single layer of the laminated glass panel is 0.1 mm to 50 mm, preferably in the range of 0.1 mm to 15 mm.

[0072] In addition, a specific pattern can be sealed in the laminate, or a specific pattern, a reflective layer, a fluorescent layer, etc. can be added to the inner and outer surfaces of the first panel 3, the second panel 4 and the third panel 8 by etching, electroplating, coating, spraying, vapor deposition, hot rolling, rolling, laminating, pressing, drawing, brushing, etc. to achieve a display effect.

[0073] In some embodiments, the insulating glass further includes a control box 7, which is an attachable controller for controlling the dimming layer 1. It primarily performs logic control and regulation functions and can be fixed within the first sealing layer. It receives control signals wirelessly. Signal connection methods include, but are not limited to, 2G, 3G, 4G, Wifi, ZigBee, Bluetooth, automatic light control, automatic temperature control, and other single or multiple control methods. The control box 7 can also be placed externally to the entire structure. When placed outside the structure, it can receive control signals wirelessly, or it can be provided with operating buttons or knobs on the control box 7 for manually sending control signals. Thus, the presence of the control box 7 enables the dimming function of the dimming layer 1 to be adjusted according to actual needs, thereby effectively expanding the scope of application of the central control glass.

[0074] Reference below Figures 4-10 The specific structures of the insulating glass according to five specific embodiments of the present invention are described.

[0076] like Figure 4-Figure 5 As shown, the insulating glass of this embodiment includes a dimming unit, a third panel 8 , a first sealing member 9 , a first spacer 11 , a first isolation member 12 , a control box 7 and an auxiliary functional layer 13 .

[0077] The dimming unit includes a dimming layer 1, an encapsulation layer 2, a first panel 3, a second panel 4, and a power supply structure 5. The encapsulation layer 2 is coated on the outside of the dimming layer 1 to encapsulate the dimming layer 1. The first panel 3 and the second panel 4 are respectively connected to the encapsulation layer 2 on either side. One end of the power supply structure 5 is connected to the dimming layer 1, and the other end is connected to the control box 7, which is used to connect to an external power source. The first panel 3 and the second panel 4 are both flat plates with a rectangular cross-section.

[0078] The third panel 8 is spaced apart from the dimming unit, and the auxiliary functional layer 13 is attached to the side of the third panel 8 facing the dimming unit. One end of the first seal 9 stops on the auxiliary functional layer 13, and the other end stops on the second panel 4. A first hollow cavity 10 is defined between the third panel 8, the first seal 9 and the second panel 4, and the first panel 3 and the dimming layer 1 are located in the first hollow cavity 10. There are two first isolators 12, and the first spacer 11 is located on the inner side of the first seal 9. One of the first isolators 12 is sandwiched between the auxiliary functional layer 13 and the first spacer 11, and the other first isolator 12 is sandwiched between the first panel 3 and the first spacer 11. The third panel 8 is a flat plate, and the first seal 9, the first spacer 11, and the first isolator 12 are all rectangular frames.

[0079] Example B:

[0080] like Figure 6As shown, the structure of the insulating glass of this embodiment is similar to that of the insulating glass of Example A, except that the third panel 8 of this embodiment is a multi-layer panel structure, and the multi-layer panel structure of the third panel 8 of this embodiment is a three-layer structure of glass-laminated-glass.

[0081] Example C:

[0082] like Figure 7 As shown, the structure of the insulating glass of this embodiment is similar to that of the insulating glass of embodiment A, except that the first panel 3, the second panel 4, and the third panel 8 of this embodiment are curved panels, and the first sealing member 9, the first spacer 11, and the first isolation member 12 are all curved frames.

[0083] Example D:

[0084] like Figure 8 As shown, the insulating glass of this embodiment includes a dimming unit, a third panel 8, a first sealant 9, a first spacer 11, a first spacer 12 and an auxiliary functional layer 13. The dimming unit includes a dimming layer 1, an encapsulation layer 2, a first panel 3, a second panel 4 and a power supply structure 5. The encapsulation layer 2 is coated on the outside of the dimming layer 1 to encapsulate the dimming layer 1. The first panel 3 and the second panel 4 are respectively connected to the two sides of the encapsulation layer 2. One end of the power supply structure 5 is connected to the dimming layer 1, and the other end is used to connect to an external power supply. The first panel 3 and the second panel 4 are both flat plates with a rectangular cross-section. The third panel 8 is spaced apart from the dimming unit, and the auxiliary functional layer 13 is attached to the side of the third panel 8 facing the dimming unit. One end of the first sealant 9 abuts against the auxiliary functional layer 13, and the other end abuts against the second panel 4. A first hollow cavity 10 is defined between the third panel 8, the first sealant 9 and the second panel 4. The first panel 3 and the dimming layer 1 are located within the first hollow cavity 10. There are two first spacers 12, and the first spacer 11 is located inside the first sealing member 9. One first spacer 12 is sandwiched between the auxiliary functional layer 13 and the first spacer 11, and the other first spacer 12 is sandwiched between the second panel 4 and the first spacer 11. The third panel 8 is a flat plate, and the first sealing member 9, the first spacer 11, and the first spacer 12 are all rectangular frames.

[0085] Example E:

[0086] like Figure 9 As shown, the structure of the insulating glass of this embodiment is similar to that of the insulating glass of Example D, except that the first panel 3, the second panel 4, and the third panel 8 of this embodiment are curved panels, and the first sealing member 9, the first spacer 11, and the first isolation member 12 are all curved frames.

[0087] Example F:

[0088] like Figure 10As shown, the structure of the insulating glass of this embodiment is similar to that of the insulating glass of Example D, except that the second panel 4 of this embodiment is a curved panel, and the first sealing member 9, the first spacer 11, and the first spacer 12 on the side close to the second panel 4 are all curved frames. By way of example, this embodiment provides a packaging method when the first panel 3 is a flat panel and the second panel 4 is a curved panel. By adjusting the lower layer of the packaging material of the packaging layer 2, the lower layer of the packaging material is thicker in the middle and thinner at the edges.

[0089] It should be noted that, in different embodiments, the first panel 3, the second panel 4 and the third panel 8 can be independently selected as curved panels or flat panels, for example: the first panel 3, the second panel 4 and the third panel 8 are all flat panels or all curved panels; or the first panel 3 and the second panel 4 are all flat panels, and the third panel 8 is a curved panel; or when the first panel 3 and the second panel 4 are both curved panels, the third panel 8 is a flat panel; or when one of the first panel 3 and the second panel 4 is a flat panel and the other is a curved panel, the third panel 8 can be a curved panel or a flat panel.

[0090] It should be noted that in the above-mentioned embodiments A, B, C, D, E, and F, the first panel 3, the second panel 4, and the third panel 8 can be square, circular, elliptical, polygonal, or any other planar shape and any shape after being punched. The first seal 9, the first spacer 11, and the first isolation member 12 can be any one of a square frame, a circular frame, an elliptical frame, and a polygonal frame. In addition, in the above five embodiments, the dimming layer 1 can be a complete dimming element or a spliced ​​structure of multiple dimming elements. The first panel 3, the second panel 4, and the third panel 8 can be a single-layer panel structure or a multi-layer panel structure.

[0091] Reference below Figure 11 A schematic structural diagram of another insulating glass according to the present invention is described.

[0092] like Figure 11 As shown, the present invention also discloses another insulating glass comprising a dimming unit, a fourth panel 14, and a second seal 15. The fourth panel 14 is spaced apart from the dimming unit. One end of the second seal 15 abuts against the fourth panel 14, and the other end abuts against the dimming unit. The dimming unit also includes a dimming seal 6, which is sandwiched between the first panel 3 and the second panel 4 and sleeved on the outside of the encapsulation layer 2. A second hollow cavity 16 is defined between the fourth panel 14, the second seal 15, and the first panel 3.

[0093] It will be appreciated that in this embodiment, the dimming unit is located outside the second hollow cavity 16, and the dimming seal 6 is sandwiched between the first panel 3 and the second panel 4, and the dimming seal 6 is sleeved on the outside of the encapsulation layer 2. This effectively reduces the impact of various environmental uncertainties on the dimming layer 1, thereby ensuring the stable performance of the dimming layer 1 and extending the service life of the dimming layer 1. Furthermore, during the manufacturing process, since the dimming unit is a pre-fabricated semi-finished product, the production cycle of the insulating glass is greatly reduced, production efficiency is improved, and large-scale production of insulating glass is more facilitated.

[0094] In this embodiment, the second hollow cavity 16 can be filled with one or more of air, nitrogen, argon, helium, neon, krypton, xenon, and carbon dioxide. The second hollow cavity 16 can also be drawn into a hollow state. The thickness of the second hollow cavity 16 ranges from 0.1 mm to 500 mm, and the preferred range is 1 mm to 100 mm. Within a certain range, the greater the thickness of the second hollow cavity 16, the better the thermal insulation effect will be. The inflation state, gas type, and thickness of the second hollow cavity 16 can be selected according to actual needs and are not limited to the above limitations. In this embodiment, the second sealing member 15 is silicone glue, silicone rubber, butyl rubber, polysulfide rubber, or other materials with sealing functions or a glass ring. Of course, the specific type of the second sealing member 15 can be selected according to actual needs and is not limited to the above limitations.

[0095] In this embodiment, the fourth panel 14 can be formed of glass, ceramic, glass-ceramic, polymeric, or a combination thereof. The lower surface of the fourth panel 14 can have a coating layer (e.g., a low-emissivity coating or other specific coating). The coating layer has a thickness ranging from 0 nm to 100 μm, preferably from 100 nm to 50 μm. The thickness of the fourth panel 14 ranges from 0 mm to 100 mm, preferably from 0.5 mm to 15 mm. Of course, in actual use, the fourth panel 14 can be made of any suitable material according to actual needs. The size and thickness of the fourth panel 14 can be selected based on actual needs and are not limited to the above.

[0096] In the insulating glass of this embodiment, the dimming unit is located outside the second hollow cavity 16, and the dimming seal 6 is sandwiched between the first panel 3 and the second panel 4, and the dimming seal 6 is sleeved on the outside of the encapsulation layer 2. This effectively reduces the impact of various environmental uncertainties on the dimming layer 1, thereby ensuring the stable performance of the dimming layer 1 and extending the service life of the dimming layer 1. In addition, because the insulating glass is further processed based on the dimming unit described above, the production cycle of the insulating glass is greatly reduced, production efficiency is improved, and large-scale production of insulating glass is more facilitated.

[0097] In some embodiments, as Figure 11 As shown, the insulating glass further includes a second spacer 17 and a second spacer 18. There are two second spacers 18, each located inside the second sealing member 15. One second spacer 18 is sandwiched between the fourth panel 14 and the second spacer 17, and the other second spacer 18 is sandwiched between the first panel 3 and the second spacer 17. Thus, the airtightness of the second hollow cavity 16 is better ensured.

[0098] In this embodiment, the material of the second spacer 17 can be one of metal materials, polymer materials, glass materials, ceramic materials, glass-ceramic materials, or a combination of any of them. The interior of the second spacer 17 can be filled with desiccant materials, which help to absorb moisture from the second hollow cavity 16, prevent water vapor from condensing on the surface of the first panel 3 and / or the third panel 8, thereby avoiding the occurrence of condensation on the surface of the hollow glass. The single-side width of the second spacer 17 ranges from 0.5mm to 500mm, and the preferred single-side width range is 3mm to 20mm. The thickness of the second spacer 17 ranges from 0.5mm to 500mm, and the preferred thickness range is 3mm to 50mm. Of course, in this embodiment, the material, internal filling, single-side width and thickness of the second spacer 17 can be selected according to actual needs and are not limited to the above-mentioned limitations.

[0099] In some embodiments, when both the first panel 3 and the second panel 4 are curved panels, the fourth panel 14 can be either a curved panel or a flat panel; or when both the first panel 3 and the second panel 4 are flat panels, the fourth panel 14 can be either a curved panel or a flat panel; and when one of the first panel 3 and the second panel 4 is a flat panel and the other is curved, the fourth panel 14 can be either a curved panel or a flat panel. Thus, insulating glass can be applied to more occasions, thereby expanding the scope of application of insulating glass.

[0100] In some embodiments, at least one of the first panel 3 , the second panel 4 , and the fourth panel 14 is a multi-layer panel structure; or the first panel 3 , the second panel 4 , and the fourth panel 14 are all single-layer panel structures.

[0101] It is understood that in actual use, certain special situations may require a structurally reinforced insulating glass structure. In this case, at least one of the first panel 3, the second panel 4, and the fourth panel 14 may be a laminated glass panel. The laminated glass may be made of polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), thermoplastic polyurethane (TPU), optically clear adhesive (OCA), ionomer, ionic plastic, optically clear resin (OCR), environmentally friendly latent curing agent (LCA), or a combination thereof. The thickness of a single layer of the laminated glass panel is 0.1-50 mm, preferably in the range of 0.1-15 mm.

[0102] In addition, a specific pattern can be sealed in the laminate, or a specific pattern, a reflective layer, a fluorescent layer, etc. can be added to the inner and outer surfaces of the first panel 3, the second panel 4 and the fourth panel 14 by etching, electroplating, coating, spraying, vapor deposition, hot rolling, rolling, laminating, pressing, drawing, brushing, etc. to achieve a display effect.

[0103] In some embodiments, as Figure 11 As shown, the insulating glass further includes an auxiliary functional layer 13, which is bonded to at least one of the first panel 3, the second panel 4, and the fourth panel 14. It is understood that the auxiliary functional layer 13 can be a plating or coating (such as a low-emissivity coating or other specific metal element, metal oxide, inorganic coating, organic coating, or other coating, either alone or in combination, with the thickness of the plating or coating ranging from 0 nm to 5 mm, preferably from 100 nm to 2 mm). It can also be an auxiliary layer such as a paint layer, a specific pattern layer, a frosted layer, a film layer, a waterproof and hydrophobic layer, etc. Thus, the addition of the auxiliary functional layer 13 can enable the insulating glass to have other functions such as reducing radiation, displaying patterns, and providing thermal insulation, thereby enabling the insulating glass of this embodiment to better meet practical needs.

[0104] In some embodiments, the insulating glass further includes a control box 7, which is an attachable controller for controlling the dimming layer 1. It primarily performs logic control and regulation functions and can be fixed within the second sealing layer. It receives control signals wirelessly. Signal connection methods include, but are not limited to, 2G, 3G, 4G, Wifi, ZigBee, Bluetooth, automatic light control, automatic temperature control, and other single or multiple control methods. The control box 7 can also be placed externally to the entire structure. When placed outside the structure, it can receive control signals wirelessly, or it can be provided with operating buttons or knobs on the control box 7 for manually sending control signals. Thus, the presence of the control box 7 enables the dimming function of the dimming layer 1 to be adjusted according to actual needs, thereby effectively expanding the scope of application of the central control glass.

[0108] The dimming unit includes a dimming layer 1, an encapsulation layer 2, a first panel 3, a second panel 4, a power supply structure 5 and a dimming seal 6. The encapsulation layer 2 is coated on the outside of the dimming layer 1 to encapsulate the dimming layer 1. The first panel 3 and the second panel 4 are respectively connected to the two sides of the encapsulation layer 2. One end of the power supply structure 5 is connected to the dimming layer 1, and the other end is connected to the control box 7. The control box 7 is used to connect to an external power supply. The dimming seal 6 is sandwiched between the first panel 3 and the second panel 4 and the dimming seal 6 is sleeved on the outside of the encapsulation layer 2. The first panel 3 and the second panel 4 are both flat panels. The fourth panel 14 is spaced apart from the dimming unit, and the auxiliary function layer 13 is attached to the side of the fourth panel 14 facing the dimming unit. One end of the second seal 15 stops on the auxiliary function layer 13, and the other end stops on the first panel 3. A second hollow cavity 16 is defined between the fourth panel 14, the second seal 15 and the first panel 3. There are two second spacers 18, with the second spacer 17 located inside the second sealing member 15. One second spacer 18 is sandwiched between the auxiliary functional layer 13 and the second spacer 17, and the other second spacer 18 is sandwiched between the first panel 3 and the second spacer 17. The fourth panel 14 is a flat plate, and the second sealing member 15, the second spacer 17, and the second spacer 18 are all rectangular frames.

[0109] It should be noted that in this embodiment, the first panel 3, the second panel 4, and the fourth panel 14 can be any of square, circular, elliptical, polygonal, or other planar shapes, and any of their corresponding shapes after being pierced. The second sealing member 15, the second spacer 17, and the second isolator 18 can be any of square, circular, elliptical, and polygonal frames. Furthermore, in the five embodiments described above, the dimming layer 1 can be a complete dimming element or a spliced ​​structure of multiple dimming elements. The first panel 3, the second panel 4, and the fourth panel 14 can be single-layer or multi-layer panels. The first panel 3, the second panel 4, and the fourth panel 14 can each independently be a curved or flat panel. For example, the first panel 3, the second panel 4, and the fourth panel 14 can all be flat or curved; or the first panel 3 and the second panel 4 can all be flat and the fourth panel 14 can be curved; or when both the first panel 3 and the second panel 4 are curved, the fourth panel 14 can be a flat panel; or when one of the first panel 3 and the second panel 4 is flat and the other is curved, the fourth panel 14 can be either a curved or flat panel.
