Description

Technical Field

[0001] This invention relates to the field of glass manufacturing technology, and in particular to an insulated glass unit with a built-in sunshade device. Background Technology

[0002] Glass is a material with high transparency, strength and hardness, and is airtight. It is chemically inert in the daily environment and does not interact with living organisms, so it has a wide range of uses. In the current technology, glass used in buildings is mainly used for sealing and lighting. However, in cold winters, the heat insulation effect of glass is not ideal, and in hot summer and cold winter or hot summer and warm winter summers, the heat insulation effect of glass is not ideal. With the rapid development of my country's economy, people's requirements for quality of life are getting higher and higher, and building doors, windows and glass curtain walls are getting bigger and bigger, which leads to an increasing proportion of heat exchange through doors, windows and glass curtain walls in the heat exchange between buildings and the outside. In order to reduce heat exchange through glass doors, windows and curtain walls, many heat-insulating glass has been developed at home and abroad in recent years. According to the structure, there are three main types: (1) insulated glass composed of two or more layers of ordinary glass; (2) insulated glass composed of glass coated with low-emissivity film; (3) vacuum glass composed of double-layer glass with negative pressure in the middle. At present, the mainstream energy-saving glass is low-emissivity coated insulated glass. This type of energy-saving glass can block some sunlight from entering the room in summer, but it still causes indoor glare, affecting the comfortable indoor lighting environment. Summary of the Invention

[0003] The purpose of this invention is to provide an insulated glass unit with a built-in sunshade device to solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This invention discloses an insulated glass unit with a built-in sunshade device, comprising an upper glass and a lower glass. The four sides of the upper and lower glass are connected by a sealing assembly. A sunshade assembly is provided in the gap between the upper and lower glass. The sunshade assembly is controlled by a driving assembly located in the gap. The driving assembly includes a transparent liquid tank, which is placed inside the end of the gap and fixed to the lower glass. The liquid tank contains a volatile liquid. Above the volatile liquid are several convex mirrors connected to the liquid tank. A push plate is provided on one side of each convex mirror, and one side of the push plate is connected to the sunshade assembly. The sunshade assembly and the liquid tank are sealed together.

[0006] Furthermore, the sealing assembly includes a sealing spacer frame and a sealant, the sealing spacer frame and the sealant being disposed between the upper glass and the lower glass, the sealing spacer frame being disposed outside the sealant, and the top and bottom of the sealing spacer frame and the sealant being fixedly connected to the bottom surface of the upper glass and the top surface of the lower glass, respectively.

[0007] Furthermore, the sealing spacer frame is one or more of the following: ceramic sealing spacer frame, metal sealing spacer frame, composite rubber strip, and fiber-reinforced resin-based composite material sealing spacer frame.

[0008] Furthermore, the sunshade assembly includes several sunshade blades, the top of which is hinged to the bottom of a push-pull rod. One end of the push-pull rod passes through a through hole with a sealing ring in the liquid tank and is connected to the push plate. The other end of the push-pull rod passes through a through hole in the upright plate and is placed in the gap. The upright plate is fixed between the upper and lower glass. Side plates are provided on both sides of the sunshade blades and are fixed to the lower glass. Rotating shafts are provided at both ends of the sunshade blades and slide in arc-shaped grooves on the inner sidewalls of the side plates.

[0009] Furthermore, the shading blades are aerogel composite panels.

[0010] Furthermore, the aerogel composite board is one of an aerogel / glass composite board or an aerogel / resin composite board.

[0011] Furthermore, the shading blades are inclinedly arranged within the interval.

[0012] Furthermore, the convex mirror is connected inside the liquid tank via a mounting bracket.

[0013] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0014] This invention can automatically adjust according to the intensity of sunlight. It uses a convex mirror to focus the volatile liquid, causing it to evaporate and increasing the pressure inside the liquid tank. This, in turn, moves the push plate and push-pull rod, which in turn rotates the sunshade blades to block sunlight. When the sunlight is not strong, the volatile liquid will condense back into liquid, the pressure inside the liquid tank will return to normal, and the push-pull rod will move the sunshade blades back to their original position.

[0021] like Figure 1-4 As shown, an insulated glass unit with a built-in sunshade device includes an upper glass 1 and a lower glass 2. The four sides of the upper glass 1 and the lower glass 2 are connected by a sealing assembly 3. The sealing assembly 3 includes a sealing spacer frame and a sealant. The sealing spacer frame and the sealant are disposed between the upper glass 1 and the lower glass 2. The sealing spacer frame is disposed on the outside of the sealant. The top and bottom of the sealing spacer frame and the sealant are respectively fixedly connected to the bottom surface of the upper glass 1 and the top surface of the lower glass 2.

[0022] The sealing spacer frame is one or more of the following: ceramic sealing spacer frame, metal sealing spacer frame, composite rubber strip, and fiber-reinforced resin-based composite material sealing spacer frame.

[0023] A sunshade assembly is provided in the gap between the upper glass 1 and the lower glass 2. The sunshade assembly is controlled by a drive assembly located in the gap. The drive assembly includes a transparent liquid tank 4, which is placed inside the end of the gap and fixed to the lower glass 2. The liquid tank 4 contains a volatile liquid 5, such as alcohol or acetone. Above the volatile liquid 5 are several convex mirrors 6 connected to the liquid tank 4 by mounting brackets 14. The position of the convex mirrors 6 is not limited to the top of the liquid tank 4, but can be set according to the purpose of the insulating glass. In general, the convex mirrors 6 will be positioned above the volatile liquid 5. A push plate 7 is provided on one side of the convex mirror 6, and one side of the push plate 7 is connected to the sunshade assembly. The sunshade assembly and the liquid tank 4 are sealed together.

[0024] The sunshade assembly includes several sunshade blades 8, which are obliquely arranged within the interval. Each sunshade blade 8 is an aerogel composite board, which can be either an aerogel / glass composite board or an aerogel / resin composite board. The top of each sunshade blade 8 is hinged to the bottom of a push-pull rod 9. One end of the push-pull rod 9 passes through a through hole with a sealing ring in the liquid tank 4 and is connected to the push plate 7. The other end of the push-pull rod 9 passes through a through hole in the upright plate 10 and is placed within the interval. The upright plate 10 is fixed between the upper and lower glass. Side plates 11 are provided on both sides of each sunshade blade 8 and are fixed to the lower glass 2. A pivot 12 is provided at both ends of each sunshade blade 8, and the pivot 12 slides within an arc-shaped groove 13 on the inner sidewall of the side plate 11.

[0025] The operation process of this invention is as follows:

[0026] In use, as the intensity of sunlight increases, the convex mirror 6 accelerates the heating of the volatile liquid 5. When heated to the evaporation temperature, the liquid turns into gas, increasing the pressure inside the liquid tank 4. This causes the push plate 7 to move outward, which in turn moves the push rod 9, thereby driving the sunshade blade 8 to rotate. The rotating shaft 12 slides in the arc groove 13, thus blocking the sunlight with the sunshade blade 8. When the intensity of sunlight decreases, the convex mirror 6 stops heating the volatile liquid 5, and the volatile liquid 5 forms a liquid at room temperature. The pressure inside the liquid tank 4 returns to normal, thus driving the sunshade blade 8 to reset via the push rod 9.

[0027] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
