Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a building curtain wall with an intelligent dimming structure. Background Technology

[0002] Building curtain walls refer to the non-load-bearing exterior wall cladding of a building. They are usually composed of panels (glass, metal, stone, ceramic, etc.) and supporting structures behind them (aluminum beams and columns, steel structures, glass ribs, etc.). Building curtain walls are composed of supporting structural systems and panels, and can have a certain displacement capacity relative to the main structure. They are building exterior envelope structures or decorative structures that do not share the loads of the main structure.

[0003] A search of the Chinese patent "A Novel High-Strength Curtain Wall Glass with Adjustable Light" (publication number CN213952649U) reveals that this patent utilizes a combination of a light-blocking flap support column, a light-blocking flap, a damping rotating shaft, and a magnetic coil. When light adjustment is needed, the photovoltaic inverter stores the electrical energy converted from the solar panels in the power control circuit. The power control circuit then controls the energization of the magnetic coil. The energized magnetic coil generates a magnetic field, which, through the mutual attraction or repulsion of two adjacent magnetic coils, precisely controls the rotation angle of the light-blocking flap. The damping rotating shaft provides damping, allowing the light-blocking flap to maintain its current angle even after the magnetic coil is de-energized, thus saving electricity. When the magnetic fields attract each other, the light-blocking flaps rotate around the damping axis and come into contact, thus blocking external sunlight and achieving the device's dimming function. The hollow chamber formed by the inner glass layer greatly improves the device's control over temperature and noise. The device controls the magnetic coils to generate a magnetic field. Two adjacent magnetic coils attract or repel each other, controlling the rotation angle of the light-blocking flaps. The light-blocking flaps can block external sunlight. However, when the device uses the light-blocking flaps to block sunlight, the dimming effect on the building curtain wall is not ideal. The light-blocking flaps require additional installation and maintenance, which may affect the building's appearance and make it inconvenient to effectively dim the building curtain wall, thus reducing the device's effectiveness. Utility Model Content

[0004] Therefore, it is necessary to provide a building curtain wall with an intelligent dimming structure to address the problem of inconvenience in effectively dimming building curtain walls.

[0005] The system includes ultra-clear glass, with two mounting glass panes on one side; a dimming mechanism, capable of effectively dimming the building curtain wall, is located on one side of the ultra-clear glass; wherein, the dimming mechanism includes PVB panes located on the other side of the mounting glass, with two PVB panes installed opposite each other, and a translucent stone material installed between the two PVB panes.

[0006] In one embodiment, the dimming mechanism further includes an anti-ultraviolet coating installed on the other side of the PVB, the anti-ultraviolet coating being disposed between the PVB and the translucent stone.

[0007] In one embodiment, polycarbonate is installed between the ultra-clear glass and one of the mounting glasses.

[0008] In one embodiment, the inner wall of the polycarbonate is fitted with an electrochromic film layer.

[0009] In one embodiment, the bottom end of the electrochromic film layer is connected to two conductive wires, one end of which extends through to the outside of the polycarbonate.

[0010] In one embodiment, the polycarbonate has two grooves at its bottom end.

[0011] In one embodiment, the inner wall of the groove is fitted with conductive wires.

[0012] Beneficial effects

[0013] The aforementioned building curtain wall with intelligent dimming structure, when dimming the building curtain wall, uses a combination of glass, PVB, and translucent stone to form a stone-glass structure. The thinness of the translucent stone enhances its light transmission effect and creates a hazy, three-dimensional light and shadow layer, improving the aesthetics of the building curtain wall. The anti-UV coating further enhances the light transmission effect of the translucent stone, while the ultra-clear glass reduces light refraction loss and improves light transmission efficiency. Polycarbonate achieves total internal reflection of light through its microstructured surface, transforming point light sources into uniform surface light sources. The multi-layered hollow structure optimizes the uniform diffusion of light, forming a three-level light control system of "transparency-semi-shading-soft light," reducing glare and adjusting the illumination to improve the dimming effect of the building curtain wall.

[0014] 1. When polycarbonate is used for dimming building curtain walls, the polycarbonate can dynamically adjust the light transmittance of the building curtain wall through the internal electrochromic film layer. The electrochromic film layer changes the light transmittance by changing the current, and gradually dims the light, thereby adjusting the light intensity and color change. When used in conjunction with polycarbonate, it can effectively dim building curtain walls.

[0015] 2. The electrochromic film layer is connected to the control unit through two conductive wires at the bottom. It communicates with the central processing unit via the CAN bus and works with the light sensor and temperature sensor to darken the glass. When the voltage polarity is reversed, the electrochromic layer returns to a transparent state, which can adjust the light transmittance of the building curtain wall. Attached Figure Description

[0028] The following is combined Figures 1-4 This invention describes a building curtain wall with an intelligent dimming structure.

[0029] In one embodiment, a building curtain wall with an intelligent dimming structure includes ultra-clear glass 100, with two mounting glass 200 disposed on one side of the ultra-clear glass 100; a dimming mechanism 300, which can effectively dim the building curtain wall, is disposed on one side of the ultra-clear glass 100; wherein, the dimming mechanism 300 includes PVB 310 disposed on the other side of the mounting glass 200, the two PVB 310 are installed opposite each other, and a translucent stone 320 is installed between the two PVB 310.

[0030] It should be noted that building curtain walls typically consist of panels and a supporting structure behind them. The panels are made of ultra-clear glass 100 as the surface layer, with polycarbonate 340 installed on the other side. An electrochromic film layer 350 is placed inside the polycarbonate 340. Glass 200, PVB 310, UV-resistant coating 330, and translucent stone 320 are combined to form a glass-stone material. Through a multi-layer hollow structure, light diffusion is optimized to achieve uniform light diffusion, forming a three-level light control of "transparency-semi-shading-soft light" and creating a double-layer heat insulation barrier to reduce the energy consumption of the building curtain wall. The glass-stone material composed of glass 200, PVB 310, UV-resistant coating 330, and translucent stone 320 is translucent but not transparent, and enhances the aesthetics of the building curtain wall. The electrochromic film layer 350 is controlled by a control unit to cause a reduction reaction of ions within the electrochromic film layer 350, adjusting the light transmittance of the building curtain wall without affecting its normal use or light transmittance.

[0031] like Figure 2 and Figure 3 As shown, the dimming mechanism 300 also includes an anti-ultraviolet coating 330 installed on the other side of the PVB 310. The anti-ultraviolet coating 330 is disposed between the PVB 310 and the translucent stone 320. A polycarbonate 340 is installed between the ultra-clear glass 100 and one of the mounting glass 200.

[0032] In this embodiment, the glass stone composed of glass 200, PVB 310, anti-ultraviolet coating 330 and translucent stone 320 forms a three-dimensional light and shadow layer, which can improve the aesthetics of the building curtain wall. In addition, it is combined with ultra-white glass 100 and polycarbonate 340 to improve the light transmittance of the building curtain wall and to control the light to a certain extent.

[0033] like Figure 4 As shown, an electrochromic film layer 350 is installed on the inner wall of the polycarbonate 340. Two conductive wires 360 are connected to the bottom end of the electrochromic film layer 350. One end of each conductive wire 360 ​​extends to the outside of the polycarbonate 340. Two grooves 370 are formed at the bottom end of the polycarbonate 340, and the conductive wires 360 are installed on the inner wall of the grooves 370.

[0034] In this embodiment, when the electrochromic film layer 350 in the polycarbonate 340 is subjected to forward and reverse voltages through two conductive lines 360, the electrode material of the electrochromic film layer 350 can change between colored and colorless through the reciprocating change of voltage, thereby dimming the building curtain wall. The groove 370 can place the conductive lines 360, which can improve the dimming effect of the building curtain wall.

[0035] Working principle: Two PVB310 layers, two UV-resistant coatings 330 layers, and translucent stone 320 layers between the two mounting glass layers 200 work together to form a glass-stone structure, improving the light and shadow effect of the building curtain wall. The ultra-clear glass 100 has a light transmittance of ≥92%, which can reduce light refraction loss and improve light transmission efficiency. The polycarbonate 340 can absorb ultraviolet rays, and when combined with the ultra-clear glass 100, it can form a light and shadow gradient effect through layering and superposition to complete the visual transition. It can also improve the sun shading effect and reduce the energy consumption of the building curtain wall. The electrochromic film layer 350 inside the polycarbonate 340 is connected to two conductive lines 360 through a control unit to apply a positive voltage. When the voltage polarity is reversed, the electrochromic film layer 350 returns to a transparent state, effectively adjusting the light of the building curtain wall.

[0036] It should be noted that the electrochromic film layer 350 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs, and the specific power supply method can be selected according to the situation, which will not be elaborated here.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0038] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
