[0025] The built-in blinds in the insulating glass structure are a new sunshade product that has just emerged in recent years. The blinds used for sunshade are perfectly integrated into the ordinary insulating glass structure, giving the ordinary insulating glass structure the function of sunshade, which has taken the integration of building sunshade a big step forward.

[0026] Hollow glass structure is made of two or three pieces of glass, using high-strength and high-airtightness composite adhesive to bond the glass sheets to an aluminum alloy frame containing a desiccant. It is a building material that has good heat insulation, sound insulation, beautiful appearance and practicality, and can reduce the weight of the building.

[0027] The blinds are integrated into the insulating glass unit and utilize built-in electrical control, allowing them to be easily raised, lowered, or tilted 180 degrees. This product not only saves space but also provides sun protection, insulation, and noise reduction, creating a fresh visual experience for both the building and the interior. Whether summer or winter, the blinds can be adjusted to provide sun protection or light and heating, significantly reducing air conditioning energy consumption. According to estimates, closed blinds can achieve energy savings of up to 40%. Due to their double-layer tempered glass structure, they offer high wind and impact resistance, making them ideal for high-rise and coastal buildings. The blinds within the insulating glass unit can be adjusted to allow full light transmission, partial light transmission, or block light. They can also be fully raised to create a fully light-transmitting window. This product leverages the unique thermal insulation, sound insulation, dust and pollution prevention, and safety benefits of insulating glass, making it an ideal solution for addressing the sunshade needs of building windows. Product features: Efficient use of space: no dedicated blind installation space is required, creating a more spacious space. Strong soundproofing, with a wide, hollow insulation layer, ensures a quiet space, enhancing soundproofing, heat insulation, thermal insulation, and windproofing. It also provides excellent sanitation, blocking dust and pollutants, creating a relaxing and pleasant living environment. Economical and practical, there's no need to worry about wear and tear on the blinds, allowing them to remain clean and in use for extended periods.

[0028] Adjusting built-in blinds requires a micromotor. Using external wiring for power is inconvenient, unsightly, and easily damages the hollow structure. Related technologies incorporate batteries within the insulating glass to provide energy. However, batteries also require charging. Currently, the industry uses crystalline silicon cells integrated within insulating glass. However, crystalline silicon is opaque and can only be manufactured in certain shapes and sizes, such as a square. Positioned at the top of the insulating glass, the cells cannot be too large, otherwise they will affect the overall light transmission, nor too small, otherwise the power generation effect will be poor.

[0029] To this end, the insulating glass structure proposed in this utility model is coated with a light-transmitting thin film chip on its surface. This light-transmitting thin film chip absorbs solar energy and converts it into electricity. This allows the light-transmitting thin film chip to serve as a charging power source for the battery while also meeting the light transmittance requirements of the insulating glass structure. This insulating glass structure of this utility model eliminates the use of crystalline silicon photovoltaic cells, which are not transparent to light, as a power source. Instead, the power for the movement of the Venetian blinds comes from the light-transmitting thin film photovoltaic chip, resulting in a larger overall light-transmitting area and a more aesthetically pleasing insulating glass structure.

[0030] The insulating glass structure provided in the embodiment of the present invention includes a first glass 100 , a second glass 200 , a venetian blind structure 300 and a dimming mechanism.

[0031] Specifically, refer to Figure 1 The first and second glass panes 100 and 200 are positioned opposite each other and bonded to the aluminum alloy frame using a high-strength, airtight composite adhesive. This creates a hollow insulation layer 400 between the first and second glass panes 100 and 200. This hollow insulation layer 400 provides both thermal and sound insulation, maintaining indoor temperature and reducing noise. A light-transmitting film chip 500 is positioned on one side of the second glass pane 200, covering the surface. This absorbs solar energy and converts it into electricity.

[0032] The venetian blind structure 300 is installed within the isolation layer 400. The blinds of the venetian blind structure 300 can be raised, lowered, or tilted at predetermined angles. Placing the venetian blind structure 300 within the isolation layer 400 not only saves space, but also provides shade, insulation, and noise reduction, while also creating a novel visual experience for the building and interior. Whether summer or winter, the venetian blind structure 300 can be adjusted to provide shade or light and heating, significantly reducing air conditioning energy consumption. According to estimates, energy savings can reach up to 40% when the blinds are closed.

[0033] It will be appreciated that, in the insulating glass structure of the present invention, the first glass 100 is located on the side facing the interior, and the second glass 200 is located on the side facing away from the interior. When the insulating glass structure is installed on a building, the second glass 200 faces the exterior. Thus, the exterior-facing side of the second glass 200 is directly exposed to sunlight, allowing the light-transmitting film chip 500 to receive solar energy and convert it into electrical energy. Furthermore, the light transmittance of the light-transmitting film chip 500 ranges from 10% to 90%, allowing external objects to be seen through the light-transmitting film chip 500 without noticeable obstruction, resulting in a good visual experience.

[0034] A dimming mechanism is provided in the isolation layer 400, which includes a battery 600 and a driving mechanism. The battery 600 is electrically connected to the light-transmitting film chip 500 to charge the battery 600 using the electric energy generated by the light-transmitting film chip 500. The driving mechanism is electrically connected to the battery 600 and is transmission-connected to the venetian blind structure 300. The driving mechanism can drive the blinds of the venetian blind structure 300 to rise, fall or rotate.

[0035] The hollow glass structure of the present invention uses the transparent film chip 500 as a charging power source for the battery 600. The transparent film chip 500 can be better processed into a transparent component to meet the requirements for light transmittance. Components with different light transmittances (from 10% to 90%) can be produced according to the lighting needs of the building. Moreover, since the transparent area and the non-transparent power generation area are staggered and evenly distributed, external objects can be seen through the transparent film chip 500 without obvious obstruction, which has a good visual effect. In addition, the transparent film chip 500 covers the surface of the second glass 200. The surface area of ​​the transparent film chip 500 is basically the same as the surface area of ​​the hollow glass structure. The power generation area is large and has the ability to generate high power, which can ensure the power supply of the battery 600 and bring great advantages to the diversification of the adjustment mode of the blinds and the selection of the micro motor used. Moreover, compared with the related art, the hollow glass structure of the present invention abandons the opaque crystalline silicon cell and covers the transparent film chip 500 on the surface of the second glass 200, thereby increasing the overall light transmission area of ​​the hollow glass structure and making the hollow glass structure more beautiful.

[0036] It is understandable that the driving mechanism may adopt a structure commonly used in related technologies, such as a structure in which a micro motor and a transmission mechanism cooperate, etc., which is not limited here.

[0037] Reference Figure 1 In some embodiments, the light-transmitting film chip 500 is disposed on the side of the second glass 200 away from the first glass 100, so that the light-transmitting film chip 500 can absorb solar energy to the maximum extent and avoid energy loss caused by sunlight reflection by the second glass 200.

[0038] Reference Figure 1 In some embodiments, a protective glass 800 is provided on the side of the light-transmitting film chip 500 facing away from the second glass 200. The protective glass 800 can protect the light-transmitting film chip 500 and prevent the light-transmitting film chip 500 from being damaged by the external environment.

[0039] It is understandable that the light-transmitting film chip 500 may also be disposed on a side of the second glass 200 close to the first glass 100 , which is not limited here.

[0040] Reference Figure 1In some embodiments, the protective glass 800 and the light-transmitting film chip 500, as well as the second glass 200 and the light-transmitting film chip 500, are bonded together via an adhesive layer 700. Prior to bonding, the adhesive layer 700 is first heated and pressurized to melt, and then applied to the surface of the second glass 200. The melted adhesive layer 700 is then placed on the second glass 200 to bond the light-transmitting film chip 500 and the second glass 200. The adhesive layer 700 is then applied to the surface of the light-transmitting film chip 500, and the protective glass 800 is then placed on the light-transmitting film chip 500 to bond the protective glass 800 and the light-transmitting film chip 500. After the adhesive layer 700 cures, the protective glass 800, the light-transmitting film chip 500, and the second glass 200 can be assembled together.

[0041] It is understandable that the protective glass can be made of tempered glass, and the adhesive layer can be made of materials such as PVB, which are not limited here.

[0042] In some embodiments, the first glass 100 is Low-E glass, and the second glass 200 is ordinary glass, such as tempered glass; or, the second glass 200 is Low-E glass, and the first glass 100 is ordinary glass, such as tempered glass, which can not only meet the requirements of thermal insulation and good light transmittance, but also reduce the cost of the insulating glass structure.

[0043] In some embodiments, the first glass 100 and the second glass 200 may both be Low-E glass, which is not limited here.

[0044] Low-E glass, also known as low-emissivity glass, is a glass product coated with multiple layers of silver or other transparent conductive materials. This coating has high transmittance for visible light and high reflection for mid- and far-infrared radiation, resulting in superior thermal insulation and light transmission compared to ordinary glass and traditional architectural coated glass. Heat loss from exterior glass windows and doors contributes significantly to a building's energy consumption, accounting for over 50%. Research indicates that heat transfer from the inner surface of glass is primarily through radiation, accounting for 58%. This means that reducing heat loss requires modifying the properties of the glass, and the most effective approach is to suppress radiation from the inner surface. Ordinary float glass has an emissivity of up to 0.84, but coating it with a silver-based low-emissivity film can reduce this to below 0.15. Therefore, using Low-E glass in building windows and doors can significantly reduce the transfer of heat from indoor spaces to the outdoors due to radiation, achieving ideal energy savings. At the same time, heat transfer through glass is bidirectional: heat can be transferred from indoors to outdoors, and vice versa, simultaneously, with the difference in heat transfer being the only issue. In winter, indoor temperatures are higher than outdoor temperatures, requiring insulation. In summer, indoor temperatures are lower than outdoor temperatures, requiring glass to provide insulation, minimizing the transfer of outdoor heat indoors. Low-E glass achieves this requirement in both winter and summer, providing both heat retention and insulation, resulting in an environmentally friendly and low-carbon solution. Therefore, using Low-E glass as the inner or outer glass of insulated built-in blinds can further enhance thermal insulation.

[0045] In some embodiments, the Low-E glass is an online Low-E glass or an offline Low-E glass. The offline Low-E glass may have a single silver, double silver, or triple silver structure.

[0046] The production process of online Low-E glass is usually carried out during the cooling process of the original float glass production process. Special equipment is used to spray liquid metal or metal powder mainly composed of tin salt directly onto the surface of the hot glass. As the glass cools, a single layer of tin oxide (SnO2) film with certain low-emissivity functional properties is formed. This special tin oxide film is the Low-E film.

[0047] Offline Low-E glass coating requires a separate coating line, most commonly a vacuum cathode magnetron sputtering line. After the glass is tempered, extremely low-emissivity silver (Ag) and other metals and metal compounds are evenly coated on the surface. This coating consists of a functional film (pure silver) and a protective film (two layers of metal oxide).

[0048] As for the relationship between the two, although there is only one word difference, the actual difference is huge. However, the advantages and disadvantages of the two cannot be directly compared, and each has its own advantages.

[0049] For online Low-E glass, the degree of bonding between the film and the glass is very high, it is very strong and wear-resistant, can be tempered and hot-bent, and can be stored normally or used directly as a single piece of glass.

[0050] Unlike online Low-E glass, offline Low-E glass is highly sensitive to the environment and difficult to store, resulting in higher production costs. When exposed to air, offline Low-E glass is more susceptible to oxidation and contamination, rendering it ineffective. It is often processed into composite products such as hollow and laminated glass.

[0051] It should be noted that the light-transmitting thin film chip 500 is a battery chip based on thin film technology.

[0052] Specifically, in some embodiments, the transparent film of the transparent film chip 500 is a laminate of one or both of a cadmium telluride film and a perovskite film, and the transparent film chip 500 has a transparent portion in the shape of a line or a predetermined pattern. The battery 600 is a lithium battery using a lithium polymer cell.

[0053] Because cadmium telluride and perovskite thin-film chips offer enhanced low-light performance, the insulating glass structure of this invention is also suitable for indoor use. Furthermore, cadmium telluride and perovskite thin-film chips possess high power generation capabilities, significantly increasing the variety of adjustment modes for built-in blinds and the selection of micromotors required. Therefore, cadmium telluride or perovskite thin-film chips are suitable as a charging power source for battery 600.

[0054] The light-transmitting film chip 500 may be screen-printed and then etched, or may be coated with photoresist and then exposed and developed before being etched, or may be directly etched by laser.

[0055] The following briefly describes the method of manufacturing the light-transmitting thin film chip 500 glass by taking the method of applying exposure resist, developing, and then etching as an example.

[0056] After the opaque chips are processed, the translucent cadmium telluride or perovskite thin-film solar cell chips are first cleaned at a speed of 200 mm / s using a pure water spray rinse to keep the cell surface clean. After cleaning, I-line positive photoresist is roll-coated over the entire chip surface at a speed of 200 mm / s. After coating, the chip is dried at 110°C. UV exposure is then performed at a wavelength of 365 nm, a UV power of 20 kW, and a speed of 200 mm / s. The mask is pre-processed according to the designed light transmission ratio. After exposure, the developer cleans the chip using a 0.5% KOH solution for 1 minute. Finally, the chip is rinsed with pure water and dried at 160°C. Then, the film is etched in a mixture of 30% HCl, 20% H2O2 and pure water in a ratio of 1:1:3, immersed in room temperature for 180 seconds. Finally, it is stripped in a 4% KOH solution at room temperature for 200 seconds to obtain a transparent cadmium telluride or perovskite thin film chip with the designed transmittance.

[0057] In one embodiment, the width of the isolation layer 400 is 24 mm, which can meet the noise reduction requirements of the insulating glass structure. It is understood that in other embodiments, the width of the isolation layer 400 can be specifically set according to actual conditions, provided that the venetian blind structure 300 can be assembled to the isolation layer 400. For example, the width of the isolation layer 400 can be between 20 mm and 30 mm, or other widths can be set, which are not limited here.

[0058] In some embodiments, the dimming mechanism is provided with a remote control receiving device that can receive command signals from a remote control to control the dimming mechanism to drive the venetian blind structure 300 to fold, unfold, or rotate. The remote control facilitates the dimming mechanism to drive the venetian blind to operate.

[0059] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
