Description

Technical Field

[0001] This invention belongs to the field of insulated glass technology, specifically relating to an insulated glass with a built-in sunshade film. Background Technology

[0002] With increasing global emphasis on energy conservation and emission reduction, building energy efficiency has become a key direction for the construction industry. Building energy consumption accounts for a significant proportion of global energy consumption, and building doors and windows, as an important component of the building envelope, account for approximately 50% of total building energy consumption. Therefore, improving the energy-saving performance of doors and windows is crucial for reducing building energy consumption and achieving sustainable development. Insulating glass with built-in shading structures, as a new type of energy-saving glass, combines the thermal insulation performance of insulating glass with the shading and light-regulating functions of shading films, effectively reducing building energy consumption and improving indoor comfort. In summer, the shading film blocks solar radiation from entering the room, lowering indoor temperature and reducing air conditioning energy consumption; in winter, the thermal insulation performance of insulating glass reduces heat loss, lowering heating energy consumption. Furthermore, insulating glass with built-in shading films also offers advantages such as aesthetics, convenience, and long service life, gradually gaining market favor.

[0003] Traditional double-glazed windows often use magnetically controlled louvered structures. Users can adjust the angle of the louvers, and when the louvers are fully closed, they can block most of the direct sunlight and reduce the amount of solar radiation heat entering the room, thus achieving a shading function. However, in practical applications, gaps will appear between the louvers, making it difficult to achieve complete shading and failing to meet users' needs for good shading effects. Summary of the Invention

[0004] (1) Technical problems to be solved To address the shortcomings of existing technologies, the present invention aims to provide an insulated glass unit with a built-in sunshade film, thereby solving the problem that existing insulated glass units use a magnetically controlled louver structure to achieve sunshade function, but in practical applications, gaps appear between the louvers, making it difficult to achieve complete light blocking and failing to meet users' needs for good light blocking effect.

[0005] (2) Technical solution To solve the above-mentioned technical problems, the present invention provides an insulated glass with a built-in sunshade film, comprising an outer glass layer, an inner glass layer, and a spacer frame installed between the outer glass layer and the inner glass layer. The outer glass layer and the inner glass layer form a cavity through the spacer frame. A drive assembly and a sunshade assembly are installed inside the cavity.

The column has an installation cavity inside. A first pulley and a second pulley are rotatably connected to the upper and lower sides of the installation cavity, respectively. A transmission belt is sleeved between the first pulley and the second pulley. An inner magnet slider is fixedly connected to the front of the transmission belt. The sunshade assembly includes a sunshade film, a first shaft and a second shaft rotatably connected to the left side of the top of the column. The first pulley is used to rotate the first shaft. A conveyor belt is sleeved between the first shaft and the second shaft. One end of the sunshade film is fixedly connected to the outer surface of the conveyor belt, and the other end of the sunshade film is fixedly connected to a counterweight rod. A light-shielding plate is fixedly connected to the top inner wall of both the outer and inner glass layers.

[0006] Preferably, the front and rear sides of the column are fixedly connected to the outer glass and the inner glass by sealant, respectively.

[0007] Preferably, the transmission belt is a synchronous belt, and a first round shaft is fixedly connected to both the left and right sides of the first pulley.

The other end of the second round shaft is rotatably connected to the inner wall of the mounting cavity through a bearing.

[0008] Preferably, a plurality of first rubber rollers are fixedly connected to the outer surface of the first rotating shaft, and a second rubber roller corresponding to the first rubber rollers is fixedly connected to the outer surface of the second rotating shaft, and the conveyor belt is sleeved on the outer surface of the first rubber rollers and the second rubber rollers.

[0009] Preferably, the right side of the first rotating shaft extends into the interior of the mounting cavity and is fixedly connected to a small gear. The first rotating shaft is rotatably connected to the column via a bearing. A large gear is fixedly connected to the outer right surface of the first round shaft, and the large gear meshes with the small gear.

[0010] Preferably, the right side of the second rotating shaft extends into the interior of the mounting cavity and is rotatably connected to a movable block via a bearing. A tension adjustment assembly is provided between the movable block and the column. An elongated hole corresponding to the second rotating shaft is provided on the left side of the column.

[0011] Preferably, the tension adjustment assembly includes an upper fixed plate and a lower fixed plate fixedly connected between the inner walls of the left and right sides of the mounting cavity. Two guide rods are fixedly connected to the lower surface of the upper fixed plate. The bottom end of the guide rod passes through the movable block and is fixedly connected to the lower fixed plate.

At this time, the shading film is rolled up or opened along the inner side of the conveyor belt, thereby improving the shading performance of the insulated glass unit through the shading film, achieving comprehensive shading, and meeting the diverse shading needs of different building scenarios.

[0016] In the above solution, by fixing light-shielding plates to the top inner walls of both the outer and inner glass layers, the gap between the first rotating shaft and the top can be blocked, improving the light-shielding effect. Furthermore, the first pulley rotates the first rotating shaft through the large and small gears, which reduces the up-and-down sliding stroke of the inner magnet slider and increases the speed at which the conveyor belt winds the sunshade film.

Detailed Implementation

[0028] This invention provides an insulated glass unit with a built-in sunshade film, comprising an outer glass layer 1, an inner glass layer 2, and a spacer frame 3 installed between the outer glass layer 1 and the inner glass layer 2. A cavity 4 is formed between the outer glass layer 1 and the inner glass layer 2 through the spacer frame 3. A drive assembly 5 and a sunshade assembly 6 are installed inside the cavity 4. The drive assembly 5 controls the opening and closing of the sunshade assembly 6. A sealing process is used between the outer glass layer 1 and the inner glass layer 2 and the spacer frame 3. Butyl rubber is used for sealing, as it has excellent airtightness and watertightness, effectively preventing gas leakage and water vapor penetration. The butyl rubber is evenly applied to the glass edge to form a sealing layer. A second seal is selected from polysulfide rubber or silicone rubber. Polysulfide rubber has good weather resistance and sealing properties, while silicone rubber has better UV resistance and anti-aging properties. During the application of the sealant, it is necessary to ensure that the sealant layer is uniform, continuous, and free of bubbles and cracks. After sealing, dry air or an inert gas, such as argon or krypton, is injected into the cavity 4 of the insulated glass unit using an inflation device. Argon and krypton have lower thermal conductivity than air, which effectively reduces heat transfer and improves insulation. Controlling the inflation pressure and volume ensures uniform gas distribution within cavity 4. The drive assembly 5 includes a column 7 installed on the inner wall of the right side of the cavity 4. The column 7 has an installation cavity 8. The upper and lower sides of the installation cavity 8 are respectively rotatably connected to a first pulley 9 and a second pulley 10. A transmission belt 11 is sleeved between the first pulley 9 and the second pulley 10. An inner magnet slider 12 is fixedly connected to the front of the transmission belt 11. The sunshade assembly 6 includes a sunshade film 13, a first rotating shaft 14 and a second rotating shaft 15 rotatably connected to the left side of the top of the column 7. The first pulley 9 is used to rotate the first rotating shaft 14. A conveyor belt 16 is sleeved between the first rotating shaft 14 and the second rotating shaft 15. One end of the sunshade film 13 is fixedly connected to the outer surface of the conveyor belt 16. The other end of the sunshade film 13 is fixedly connected to a counterweight rod 17. A light-shielding plate 18 is fixedly connected to the inner wall of the top of both the outer glass 1 and the inner glass 2. The light-shielding plate 18 is used to block the gap between the first rotating shaft 14 and the top, so as to achieve complete light blocking.

[0029] In order to fix column 7, such as Figure 1 and Figure 2 As shown, in this embodiment, the front and rear sides of the column 7 are fixedly connected to the outer glass 1 and the inner glass 2 by sealant, respectively, and the column 7 and the spacer frame 3 have the same thickness.

[0030] In order to better transmit power between the first pulley 9 and the second pulley 10, such as... Figure 7 and Figure 8As shown, in this embodiment, the transmission belt 11 is a synchronous belt. The first pulley 9 is fixedly connected to the left and right sides of the first round shaft 901. The other end of the first round shaft 901 is rotatably connected to the inner wall of the mounting cavity 8 through a bearing. The second pulley 10 is fixedly connected to the left and right sides of the second round shaft. The other end of the second round shaft is rotatably connected to the inner wall of the mounting cavity 8 through a bearing.

[0031] like Figure 4 and Figure 8 As shown, in this embodiment, a plurality of first rubber rollers 1401 are fixedly connected to the outer surface of the first rotating shaft 14, and a second rubber roller 1501 corresponding to the first rubber rollers 1401 is fixedly connected to the outer surface of the second rotating shaft 15. The conveyor belt 16 is sleeved on the outer surface of the first rubber rollers 1401 and the second rubber rollers 1501. Through the first rubber rollers 1401 and the second rubber rollers 1501, the friction between the conveyor belt 16 and the first rotating shaft 14 and the second rotating shaft 15 is increased, so as to better wind the sunshade film 13 together from the inside.

[0032] like Figure 7 and Figure 8 As shown, in this embodiment, the right side of the first rotating shaft 14 extends into the interior of the mounting cavity 8 and is fixedly connected to a small gear 1402. The first rotating shaft 14 is rotatably connected to the column 7 through a bearing. A large gear 902 is fixedly connected to the outer right surface of the first round shaft 901, and the large gear 902 meshes with the small gear 1402. In this way, by using the outer magnet slider on the outer frame of the hollow glass, when the inner magnet slider 12 moves upward, the first round shaft 901 drives the large gear 902 to rotate. The cooperation between the large gear 902 and the small gear 1402 enables the conveyor belt 16 to wind faster.

[0033] To adjust the tension between the first rotating shaft 14 and the second rotating shaft 15, such as Figure 8As shown, in this embodiment, the right side of the second rotating shaft 15 extends into the interior of the mounting cavity 8 and is rotatably connected to a movable block 1502 via a bearing. A tension adjusting assembly 1503 is provided between the movable block 1502 and the column 7. An elongated hole 1504 corresponding to the second rotating shaft 15 is provided on the left side of the column 7. The tension adjusting assembly 1503 includes an upper fixing plate 1505 and a lower fixing plate 1506 fixedly connected between the inner walls of the left and right sides of the mounting cavity 8. Two guide rods 1507 are fixedly connected to the lower surface of the upper fixing plate 1505. The bottom ends of the guide rods 1507 penetrate the movable block 1502 and are connected to the lower fixing plate 1506. 6. Fixed connection: The guide rod 1507 is slidably connected to the movable block 1502. A spring 1508 is sleeved on the outer surface of the guide rod 1507 between the movable block 1502 and the upper fixed plate 1505. One end of the spring 1508 is fixedly connected to the movable block 1502, and the other end of the spring 1508 is fixedly connected to the upper fixed plate 1505. The movable block 1502 is located between the front and rear sides of the transmission belt 11. This not only saves space, but also allows the restoring force of the spring 1508 to make the movable block 1502 slide along the guide rod 1507, so that the movable block 1502 always has a downward force driving the second rotating shaft 15.

[0034] In this embodiment, the first rotating shaft 14 and the second rotating shaft 15 are hollow structures, and the first rotating shaft 14 and the second rotating shaft 15 are made of high-strength aluminum alloy material. The sunshade film 13 is a thin film structure with smooth sides and is made of PTFE film. The sunshade film 13 extends to the inner walls of the left and right sides, and the smooth thin film structure has low friction when winding, which facilitates winding. The surface of the sunshade film 13 usually has a reflective coating that can reflect most of the infrared and ultraviolet rays in solar radiation. When sunlight shines on the sunshade film 13, the reflective coating will reflect the light back, reducing the solar radiation energy entering the room. The light scattering effect of the sunshade film 13 can also make the light entering the room more uniform, reduce the generation of glare, and improve the visual comfort of the room. In addition, the sunshade film 13 has a darker color and a greater thickness, resulting in a better sunshade effect.

[0035] like Figure 5 and Figure 6 As shown, in this embodiment, the front of the column 7 is provided with a sliding hole 701 corresponding to the inner magnet slider 12. The upper and lower sides of the front of the inner magnet slider 12 are provided with grooves 1201. The inner wall of the groove 1201 is rotatably connected to a guide wheel 1202. In this way, when in use, a frame is installed on the outside of the hollow glass. An outer magnet slider corresponding to the inner magnet slider 12 is adjustablely set on the frame. By pushing the outer magnet slider, the inner magnet slider 12 is moved. At this time, the guide wheel 1202 on the inner magnet slider 12 contacts the outer glass 1 and rotates, reducing the resistance during movement.

[0036] The technical solution provided by this invention involves setting a drive assembly 5 and a sunshade assembly 6 inside the insulating glass, fixing the sunshade film 13 on the conveyor belt 16 between the first rotating shaft 14 and the second rotating shaft 15, and setting a counterweight rod 17 at the bottom of the sunshade film 13. Using the outer magnet slider on the outer frame of the insulating glass, the inner magnet slider 12 is moved upward. During the movement of the inner magnet slider 12, the transmission belt 11 is rotated. During the rotation of the transmission belt 11, the first pulley 9, the second pulley 10, the first round shaft 901 and the large gear 902 are rotated. During the rotation of the large gear 902, it cooperates with the small gear 1402 to drive the first rotating shaft 14 to rotate. During the rotation of the first rotating shaft 14, it cooperates with the second rotating shaft 15 to drive the conveyor belt 16 to rotate. During the rotation of the conveyor belt 16, one end of the sunshade film 13 is wound until the inner magnet slider 12 moves to the upper side and the sunshade film 13 is wound along the inner side of the conveyor belt 16. At this time, the sunshade film 13 is fully opened. When the inner magnet slider 12 moves downward, it drives the first rotating shaft 14, the second rotating shaft 15 and the conveyor belt 16 to rotate in the opposite direction. At this time, due to the gravity of the counterweight rod 17 at the bottom of the sunshade film 13, the sunshade film 13 moves downward and completely blocks the outer glass 1. Thus, the sunshade film 13 improves the sunshade performance of the insulating glass, achieves full sunshade, and meets the diverse sunshade needs of different building scenarios.
