Description

Technical Field

[0001] This utility model relates to the field of curtain wall glass technology, and in particular to a smart glass applied to BIPV curtain walls. Background Technology

[0002] Existing curtain walls are mostly designed with dimming functions. When the sunlight is strong, the film is in a fogged state to provide shade; in the evening or when the weather is bad and the sunlight is weak, the dimming film is turned into a transparent state. The dimming film consumes electricity and has poor energy-saving effect.

[0003] Currently, some dimming curtain wall glass designs are also available on the market that incorporate power generation capabilities. However, these designs are often flawed and difficult to implement. For example, patent CN214658252U discloses a type of dimming glass for solar power generation, which includes a first tempered glass layer, a second tempered glass layer, and a third tempered glass layer in sequence along the light incident direction. A hollow layer is provided between the first and second tempered glass layers, and a solar cell is installed in the hollow layer. Connecting wires are installed on the solar cell. A thermochromic layer is provided between the second and third tempered glass layers, and the thermochromic layer is made of a thermochromic material. A conductive film is provided on the side of the second tempered glass layer facing the third tempered glass layer, and the conductive film is connected to the solar cell through connecting wires.

The battery box is placed in the structural adhesive and connected to the dimming film and the photovoltaic chip layer respectively via cables.

[0007] Further:

[0008] The dimming glass is laminated dimming glass.

[0009] The photovoltaic glass is a laminated photovoltaic glass.

[0010] The battery box integrates a controller and a rechargeable battery.

[0011] The battery box is located near the edge of the structural adhesive.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0023] like Figures 1 to 3 As shown, the smart glass used in BIPV curtain walls includes an architectural glass structure, a dimming film 2, a photovoltaic power generation chip layer 6, and a battery box 8. The architectural glass structure includes a set of architectural glass, with the dimming film placed between two architectural glass pieces to form a dimming glass, and the photovoltaic power generation chip layer placed between two other architectural glass pieces to form a photovoltaic power generation glass. The edges between the dimming glass and the photovoltaic power generation glass are sealed with structural adhesive to form an integral insulated glass. The battery box is placed in the structural adhesive and connected to the dimming film and the photovoltaic power generation chip layer respectively via cables 10.

[0024] Furthermore: the dimming glass is laminated dimming glass; the photovoltaic power generation glass is laminated photovoltaic power generation glass. The laminated photovoltaic power generation glass and the laminated dimming glass, when combined, form an insulated glass structure using structural adhesive. This structure provides dimming and power generation functionality, is simple in structure, and easy to manufacture.

[0025] The battery box integrates the controller and rechargeable battery 9. The battery box is located near the structural adhesive edge, and its outer side has a cover for easy maintenance or controller replacement. Furthermore, the cover has ventilation holes for stable and reliable operation.

[0026] First, architectural glass I1, dimming film 2, and architectural glass II3 are combined to form laminated dimming glass; then, architectural glass III5, photovoltaic chip layer 6, and architectural glass IV7 are combined to form laminated photovoltaic glass; then, the laminated photovoltaic glass and laminated dimming glass are combined into an integral insulating glass unit through a hollow layer 4 (sealed with structural adhesive). At the top of the insulating glass unit, the battery box is placed in the structural adhesive, with the upper surface of the battery box flush with the upper surface of the structural adhesive. Cables are led out from the photovoltaic chip layer to the battery box and connected to the charging port of the rechargeable battery; cables are also led out from the dimming film layer to the battery box and connected to the discharging port of the rechargeable battery. At this point, the structure of this product is complete.

[0027] Working principle: In the morning, sunlight shines on the photovoltaic chip layer of this product, generating electricity. This electricity charges the rechargeable battery. During the charging process, the rechargeable battery cannot discharge, so the dimming film has no power supply and becomes atomized, thus providing sun shading. In the evening, when the sunlight weakens, the photovoltaic chip stops generating electricity, and the rechargeable battery is in a discharging state. The dimming film is then powered by the rechargeable battery and becomes transparent. By controlling the change in outdoor light intensity, the product achieves automatic dimming.

[0028] This patented product utilizes the principles of photovoltaic power generation, battery charging without discharging and discharging without charging, and dimming film that becomes transparent when powered on and fogged when powered off. It achieves automatic adjustment of the glass's shading and light transmission based on changes in outdoor light intensity. It integrates traditional architectural glass, photovoltaic power generation chips, rechargeable batteries, and dimming film into a new type of architectural glass that can generate electricity and automatically adjust the light, making it energy-saving and environmentally friendly.

[0029] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.

[0030] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner.
