Description

Technical Field

[0001] This application belongs to the field of building structure technology, and in particular relates to a type of architectural glass. Background Technology

[0002] A dome is a common type of architectural glass. It's a design that uses glass as the primary material and covers the top opening of a building through an arched or spherical structure. Domes are commonly found in large public spaces such as atriums, shopping malls, and exhibition halls. Their core function is to introduce natural light while creating a unique spatial aesthetic.

[0003] In large shopping malls and exhibition halls, domes are commonly seen at the top. These domes are mainly composed of a framework and multiple glass panels mounted on it. However, these dome glass panels typically have high visible light transmittance. This results in higher temperatures below the dome compared to the surrounding area during midday in summer when solar radiation is high, increasing air conditioning energy consumption. Furthermore, the high ultraviolet transmittance, especially in some exhibition halls, can cause exhibits to fade or even be damaged. To address these issues, some shopping malls and exhibition halls have designed the dome glass to have lower transmittance, reducing the amount of light entering the room. However, this results in dim indoor lighting on cloudy days, increasing indoor lighting energy consumption.

[0004] In summary, the light transmittance of the current dome is either too high or too low, which will increase energy consumption and cannot meet the light transmittance requirements in different weather conditions. Utility Model Content

[0005] In view of this, embodiments of this application provide an architectural glass to solve the technical problem that the light transmittance of existing architectural glass cannot meet the usage requirements.

[0006] This application provides an embodiment of architectural glass, comprising:

[0007] A central glass pane, located at the center of the architectural glass;

[0008] At least one set of annular or near-annular glass units, the glass units being arranged circumferentially along the central glass, the glass units comprising electrochromic glass;

[0009] An extension component is provided at the edge of the electrochromic glass; and

[0010] A controller, which is connected to the lead-out component, is used to control the color change of the electrochromic glass to adjust the light transmittance of the architectural glass.

[0011] By incorporating electrochromic glass into architectural glass and then connecting it to an external circuit via a controller, voltage is applied to the electrochromic glass, causing it to change color and thus adjusting the light transmittance of the entire building glass or a specific area. Specifically, in sunny weather with strong sunlight, the controller can darken the electrochromic glass to absorb most of the sunlight, reducing light transmission and preventing excessively high indoor temperatures. On cloudy days, voltage can be withheld to keep the glass transparent, maximizing light transmittance and reducing indoor lighting energy consumption.

[0012] Optionally, the electrochromic glass includes a first glass, an electrochromic film, and a second glass arranged sequentially.

[0013] The electrochromic film includes two oppositely arranged long sides and two oppositely arranged short sides. The short sides include a first short side and a second short side, with the first short side being longer than the second short side. The lead-out component is located in the region of the long side close to the first short side. This design, with the lead-out component positioned close to the first short side, avoids a further widening of the color-changing rate difference between the regions of the electrochromic film close to the first and second short sides due to voltage drop in the lead-out component, preventing overcharging and over-discharging in the region close to the second short side due to excessively rapid color change. Furthermore, the position of the lead-out component facilitates wiring, simplifies installation, and reduces maintenance costs. This design optimizes space utilization and adapts to different application scenarios, such as the specific shape requirements of building or automotive sunroofs.

[0014] Optionally, the edge of the long side is formed with a plurality of first electrodes of the same polarity and a plurality of second electrodes of the same polarity, and the lead-out assembly includes a first lead-out electrode and a second lead-out electrode;

[0015] The electrochromic film has a first busbar and a second busbar on its edge. The first busbar is connected to a plurality of first electrodes, and the second busbar is connected to a plurality of second electrodes. The first lead-out electrode is connected to the first busbar, and the second lead-out electrode is connected to the second busbar.

[0016] The first and second lead-out electrodes are located on the same long side of the electrochromic film. This effectively reduces the number of lead-out electrodes; only one pair of lead-out electrodes is needed to control the on / off state of the electrodes at the edge of the film, greatly simplifying the structural design and saving space for external circuits and electrical components.

[0017] Optionally, the electrochromic film comprises a first substrate layer, a first conductive layer, an electrochromic layer, a second conductive layer, and a second substrate layer stacked sequentially.

[0018] The electrochromic film has multiple first grooves on one edge, exposing a portion of the second conductive layer to form multiple first electrodes. The electrochromic film also has multiple second grooves on the other edge, exposing a portion of the first conductive layer to form multiple second electrodes. The first and second grooves are staggered and located along the long side of the electrochromic film. This staggered arrangement of grooves results in a multi-point distribution of electrodes, effectively preventing electric field attenuation in the central region of the film and ensuring a uniform electrochromic layer reaction (reducing color spots).

[0019] Optionally, the electrochromic film is shaped like a fan-shaped ring or an isosceles trapezoid, and the shapes of the first and second glass pieces are consistent with the shape of the electrochromic film. This ensures that multiple electrochromic glasses can be spliced ​​together to form a ring-shaped or near-ring-shaped glass unit, facilitating assembly.

[0020] Optionally, the glass unit comprises multiple ordinary glass panes and multiple electrochromic glass panes, with the ordinary glass and electrochromic glass panes alternately arranged circumferentially along the central glass pane. The advantage of this arrangement is that the alternating arrangement can balance the stability of the overall structure. Simultaneously, the alternating arrangement allows for functional zoning control; different areas can independently adjust their light transmittance, such as different parts of a building curtain wall, which can be adjusted as needed, saving energy. Circumferential arrangement refers to a ring-shaped or circular structure, such as a dome or circular curtain wall. In this case, alternating the use of two types of glass may optimize light distribution, reduce overall energy consumption, and maintain visual continuity. Furthermore, cost is also a factor, as electrochromic glass is more expensive than ordinary glass; alternating use can reduce costs while maintaining a certain degree of intelligent dimming functionality. If all glass is electrochromic, maintenance costs would be high if any part malfunctions. An alternating arrangement may allow for modular replacement, reducing maintenance difficulty. In addition, an alternating arrangement may aid in thermal management, as ordinary glass has varying insulation properties; alternating use may balance temperature distribution and reduce thermal stress.

[0021] Optionally, the lead-out electrodes on each of the electrochromic glasses are positioned in the same location. This facilitates standardized wiring and simplifies structural design.

[0022] Optionally, each of the electrochromic glass panes is equipped with one of the controllers. This allows for individual control of each electrochromic glass pane, ensuring that even if one electrochromic glass pane fails or becomes uncontrollable, the overall light transmittance requirement of the building's glass system is not affected.

[0023] Optionally, the glass unit comprises at least two sets, wherein each set of glass units has a different size, and the glass units farther from the central glass are larger. This ensures that the final architectural glass is circular or near-circular, enhancing its aesthetic appeal.

[0024] Optionally, the glass unit comprises at least two sets, with ordinary glass and electrochromic glass alternately arranged radially in the building glass. Alternating between ordinary glass and electrochromic glass can create multi-layered insulation; for example, an outer layer of ordinary glass, a middle layer of electrochromic glass, and an inner layer of ordinary glass. This controls heat transfer at different layers, reducing the overall heat transfer coefficient and improving insulation performance. Simultaneously, the electrochromic glass can adjust light transmission as needed, reducing the indoor air conditioning load. Furthermore, multi-layered electrochromic glass can be adjusted in stages; for example, the outer layer can be darkened to absorb more solar radiation, while the inner layer remains transparent to maintain light transmission. This layered control is more flexible than single-layer control, adapting to different lighting conditions and improving comfort. The staggered arrangement can balance the differences in the expansion coefficients of different materials, reducing deformation or breakage caused by thermal stress. The different material properties of ordinary glass and electrochromic glass, combined with their alternating arrangement, can disperse stress and improve overall wind pressure and earthquake resistance.

[0025] Optionally, the central glass is electrochromic glass. The light transmittance at the center of the architectural glass can be adjusted.

[0026] Optionally, the central glass can be either circular or a regular polygon. This allows for targeted adaptation of annular electrochromic glass and isosceles trapezoidal electrochromic glass. Attached Figure Description

[0048] This application provides an embodiment of architectural glass, such as... Figure 1 and Figure 2 As shown, the architectural glass includes a central glass 10, a glass unit 20, an extension assembly 30, and a controller 40;

[0049] The central glass 10 is located at the center of the building's glass;

[0050] At least one set of glass units 20 are provided, and the shape of the glass units 20 is annular or quasi-annular. The glass units 20 are arranged around the central glass 10. The glass units 20 include electrochromic glass 22.

[0051] The lead-out component 30 is disposed at the edge of the electrochromic glass 22;

[0052] The controller 40 is connected to the lead-out component 30. The controller 40 is used to control the color change of the electrochromic glass 22 to adjust the light transmittance of the architectural glass.

[0053] The architectural glass provided in this application embodiment incorporates electrochromic glass 22. A controller 40 connects to an output component 30 to control an external circuit applying voltage to the electrochromic glass 22, causing it to change color and thus adjusting the light transmittance of the entire architectural glass or a specific area. Specifically, in sunny weather with strong sunlight, the controller 40 controls the electrochromic glass 22 to darken its color, absorbing most of the sunlight and reducing light transmission to the architectural glass, preventing excessively high indoor temperatures. On cloudy days, no voltage is applied to the electrochromic glass 22, keeping it transparent to ensure maximum light transmittance and reduce indoor lighting energy consumption.

[0054] Optionally, such as Figures 1 to 3 As shown, the electrochromic glass 22 includes a first glass 221, an electrochromic film 222, and a second glass 223 arranged sequentially.

[0055] The electrochromic film 222 includes two oppositely arranged long sides and two oppositely arranged short sides. The short sides include a first short side and a second short side, with the first short side being longer than the second short side. The lead-out component 30 is located on the long side near the first short side. This design, with the lead-out component 30 positioned close to the first short side, avoids a further widening of the color-changing rate difference between the areas of the electrochromic film 222 near the first and second short sides due to voltage drop in the lead-out component 30. It also avoids overcharging and over-discharging due to excessively rapid color change in the area near the second short side. Furthermore, the position of the lead-out component 30 facilitates wiring, simplifies installation, and reduces maintenance costs. This design optimizes space utilization and adapts to different application scenarios, such as the specific shape requirements of architectural glass or automotive sunroofs.

[0056] Optionally, such as Figure 4 and Figure 5 As shown, the long side of the electrochromic film 222 is formed with a plurality of first electrodes 203 of the same polarity and a plurality of second electrodes 204 of the same polarity, and the lead-out assembly 30 includes a first lead-out electrode 31 and a second lead-out electrode 32.

[0057] The edge of the electrochromic film 222 is provided with a first busbar 205 and a second busbar 206. The first busbar 205 is connected to a plurality of first electrodes 203, and the second busbar 206 is connected to a plurality of second electrodes 204. The first lead-out electrode 31 is connected to the first busbar 205, and the second lead-out electrode 32 is connected to the second busbar 206.

[0058] The first lead-out electrode 31 and the second lead-out electrode 32 are located on the same long side of the electrochromic film 222. This effectively reduces the number of lead-out electrodes; only one pair of lead-out electrodes is needed to control the on / off state of the electrodes at the edge of the film, greatly simplifying the structural design and saving space for external circuits and electrical components.

[0059] It should be noted that the edge of the long side mentioned above refers to the edge of the electrochromic film corresponding to the long side. Specifically, the electrochromic film has an upper surface and a lower surface arranged opposite to each other, and an electrode is formed at the edge of the long side, that is, an electrode is formed on the upper or lower surface of the electrochromic film.

[0060] In applications, the first lead-out electrode 31 and the second lead-out electrode 32 can be flexible circuit boards, rolled copper / aluminum foil, electrolytic copper / aluminum foil, etc., and the material can be aluminum, copper, silver, tin, or other conductive elemental metals, non-metallic semiconductor conductive materials, their platings, or other conductive metal oxides or combinations thereof. The lead-out electrodes can also be directly formed as a power supply with a control module to directly achieve conductivity of the electrochromic layer.

[0061] Optionally, one end of the lead-out component 30 is connected to the electrochromic film 222, and the other end of the lead-out component 30 extends from the edge of the electrochromic glass 22. Specifically, one end of the first lead-out electrode 31 is connected to the first busbar 205, and the other end of the first lead-out electrode 31 extends from the edge of the electrochromic glass 22; one end of the second lead-out electrode 32 is connected to the second busbar 206, and the other end of the second lead-out electrode 32 extends from the edge of the electrochromic glass 22.

[0062] Furthermore, the first busbar 205 sequentially passes through the first long side, the first short side, and the second long side, connecting the first electrode 203 on the two long sides; the second busbar 206 sequentially passes through the first long side, the second short side, and the second long side, connecting the second electrode 204 on the two long sides; wherein, the polarities of the first electrode 203 and the second electrode 204 are opposite, that is, when the first electrode 203 is the positive electrode, the second electrode 204 is the negative electrode, and when the first electrode 203 is the negative electrode, the second electrode 204 is the positive electrode. By having the first busbar 205 and the second busbar 206 pass through two different short sides, the thickness of the entire electrochromic film 222 can be made uniform, avoiding excessive thickness near one short side, which would affect subsequent lamination processes and the overall aesthetics. In application, the busbar can be, but is not limited to, conductive copper foil, conductive adhesive, and conductive resin, or other conductive materials, thereby forming a multi-electrode structure at the edge of the film and accelerating the color-changing speed of the film. The first and second busbars can be made of conductive materials well known to those skilled in the art, such as at least one of conductive silver paste, conductive copper paste, conductive carbon paste, nano-silver conductive ink, copper foil, copper wire, and conductive adhesive film. In other embodiments, the first busbar 205 and the second busbar 206 are disposed on the edges of the long sides of the electrochromic film 222, and each long side is provided with a first busbar 205 and a second busbar 206. Each first busbar 205 is provided with a first lead-out electrode 31, and each second busbar 206 is provided with a second lead-out electrode 32. The first lead-out electrode 31 and the second lead-out electrode 32 are paired to form positive and negative electrodes; thus, the current or voltage on the two long sides is controlled to be switched on or off by the two pairs of lead-out electrodes respectively.

[0063] Optionally, such as Figure 5 As shown, the electrochromic film 222 includes a first base layer 2221, a first conductive layer 2222, an electrochromic layer 2223, a second conductive layer 2224, and a second base layer 2225 stacked sequentially.

[0064] Multiple first grooves 201 are formed on one edge of the electrochromic film 222, exposing a portion of the second conductive layer 2224 to form multiple first electrodes 203. Multiple second grooves 202 are formed on the other edge of the electrochromic film 222, exposing a portion of the first conductive layer 2222 to form multiple second electrodes 204. The first grooves 201 and second grooves 202 are staggered and located on the long side of the electrochromic film 222. In this way, the staggered grooves make the electrodes distributed at multiple points, effectively avoiding the attenuation of the electric field in the central area of ​​the film, and ensuring that the electrochromic layer 2223 reacts uniformly (reducing color spots).

[0065] In applications, both the first substrate layer 2221 and the second substrate layer 2225 are transparent substrates. The "transparent substrate" is an optically grade transparent material, specifically a flexible substrate material such as polyethylene terephthalate (PET), polycarbonate (PC), polyimide (PI), cyclic olefin copolymers, or cellulose triacetate. The first substrate layer 2221 and the second substrate layer 2225 can also be glass substrates.

[0066] Both the first conductive layer 2222 and the second conductive layer 2224 are transparent conductive layers. The material of the "transparent conductive layer" can be indium-tin oxide (ITO), aluminum zinc oxide (AZO), fluorine-doped tin oxide (FTO), silver nanowires, graphene, carbon nanotubes, metal meshes, or silver nanoparticles, etc.

[0067] The electrochromic layer 2223 is a sheet composed of one or more layers of gel-state or solid materials, such as polymer-dispersed liquid crystal (PDLC) layers, suspended particle devices (SPD) layers, and electrochromic (EC) layers. For the electrochromic (EC) type electrochromic layer 2223, it may include a color-changing material layer, an electrolyte layer, and an ion storage layer stacked sequentially. The materials of the color-changing material layer, electrolyte layer, and ion storage layer can be those found in the prior art, and this application does not impose any special limitations on them.

[0068] Optionally, the electrochromic film 222 is shaped like a fan-shaped annulus or an isosceles trapezoid, and the shapes of the first glass 221 and the second glass 223 are consistent with the shape of the electrochromic film 222. In this way, multiple electrochromic glasses 22 can be spliced ​​together to form a ring or quasi-ring glass unit 20, which is convenient for assembly.

[0069] Specifically, in the same electrochromic glass 22, the first glass 221, the second glass 223, and the electrochromic film 222 form a contoured structure, with the glass dimensions slightly larger than the film, thus facilitating the clamping of the electrochromic film 222 between the two glass pieces. Optionally, sealing elements are provided at the edges of the first glass 221 and the second glass 223 to prevent moisture from entering the electrochromic glass 22. These sealing elements can be sealant or sealing strips.

[0070] In applications, such as Figure 1 and Figure 6 As shown, the architectural glass is dome-shaped, with the central glass 10 being circular, the glass unit 20 being annular, and the ordinary glass 21 and electrochromic glass 22 both being fan-shaped. Figure 7 and Figure 8 As shown, the architectural glass is dome-shaped, the central glass 10 is polygonal, the glass unit 20 is ring-shaped, and the platform glass and electrochromic glass 22 are isosceles trapezoids.

[0071] Optionally, such as Figure 1 and Figure 6 As shown, glass unit 20 includes multiple ordinary glass 21s and multiple electrochromic glass 22s, which are arranged alternately along the circumference of the central glass 10. The advantage of this arrangement is that the alternating arrangement of ordinary glass 21s and electrochromic glass 22 can balance the stability of the overall structure. Simultaneously, the alternating arrangement allows for functional zoning control; different areas can independently adjust their light transmittance, such as different parts of a building curtain wall, which can be adjusted as needed, saving energy. Circumferential arrangement refers to ring-shaped or circular structures, such as domes or circular curtain walls. In this case, alternating the use of two types of glass may optimize light distribution, reduce overall energy consumption, and maintain visual continuity. Furthermore, cost is also a factor, as electrochromic glass 22 is more expensive than ordinary glass 21; alternating its use can reduce costs while maintaining a certain degree of intelligent dimming functionality. If all electrochromic glass 22 is used, maintenance costs would be high if any part malfunctions. Alternating arrangement may allow for modular replacement, reducing maintenance difficulty. In addition, alternating arrangements may help with thermal management because the thermal insulation properties of ordinary glass 21 vary, and alternating use may balance the temperature distribution and reduce thermal stress.

[0072] In other embodiments, the glass unit 20 may also be composed entirely of electrochromic glass 22, thus allowing for adjustment of the light transmittance over the entire area of ​​the building glass.

[0073] Optionally, such as Figure 1 and Figure 2 As shown, the lead-out electrodes on each electrochromic glass 22 are positioned in the same location. This facilitates standardized wiring and simplifies the structural design.

[0074] Optionally, each electrochromic glass 22 is equipped with a controller 40. This allows for individual control of each electrochromic glass 22, ensuring that even if one electrochromic glass 22 fails or becomes uncontrollable, the overall light transmittance requirement of the building glass is not affected.

[0075] Optionally, such as Figure 1 , Figure 7 andFigure 8 As shown, the glass unit 20 has at least two sets, each set of glass units 20 having a different size, and the glass unit 20 further away from the central glass 10 has a larger size. This ensures that the final architectural glass is circular or near-circular, enhancing its aesthetic appeal.

[0076] Optionally, such as Figure 1 and Figure 7 As shown, the glass unit 20 has at least two sets, with ordinary glass 21 and electrochromic glass 22 alternately arranged in the radial direction of the architectural glass. The alternation of ordinary glass 21 and electrochromic glass 22 can form multi-layered insulation; for example, the outer layer can use ordinary glass 21, the middle layer can use electrochromic glass, and the innermost layer can use ordinary glass again. This controls heat transfer at different layers, reduces the overall heat transfer coefficient, and improves the insulation effect. Simultaneously, the electrochromic glass 22 can adjust light transmission as needed, reducing the indoor air conditioning load. Furthermore, the multi-layered electrochromic glass 22 can be adjusted in stages; for example, the outer layer can be darkened to reflect more solar radiation, while the inner layer remains transparent to maintain light transmission. This layered control is more flexible than single-layer control, adapting to different lighting conditions and improving comfort. The staggered arrangement can balance the differences in the expansion coefficients of different materials, reducing deformation or breakage caused by thermal stress. The different material properties of ordinary glass 21 and electrochromic glass 22, combined with their alternating arrangement, can disperse stress and improve overall wind pressure and earthquake resistance.

[0077] Optionally, the central glass 10 is electrochromic glass 22. The light transmittance at the center of the building glass can be adjusted.

[0078] Optionally, the central glass 10 can be either circular or a regular polygon. This allows for targeted adaptation of both annular and isosceles trapezoidal electrochromic glass 22.

[0079] Optionally, such as Figure 1 As shown, the architectural glass also includes a mounting bracket 50, on which the central glass 10, glass unit 20, and controller 40 are all mounted. The presence of the mounting bracket 50 improves the overall stability of the architectural glass and facilitates the installation of the central glass 10 and glass unit 20, especially the electrochromic glass 22. Specifically, the mounting bracket can be a frame, which can also be hollow to allow for the routing of electrical wires, thus facilitating the wiring of the electrochromic glass 22.
