DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1 and Figure 2 , an electrochromic glass with environmental adaptability, comprising a first glass panel 1, a second glass panel 2 and a third glass panel 3, an electrochromic layer 4 is arranged on the inner surface of the first glass panel 1, a PVB isolation layer 5 is arranged between the first glass panel 1 and the second glass panel 2, a sealing strip 7 is arranged between the second glass panel 2 and the third glass panel 3, and the sealing strip 7 is a frame-shaped structure, a thermochromic material layer 6 is arranged between the second glass panel 2 and the third glass panel 3 and inside the sealing strip 7, a sealant 10 is arranged between the second glass panel 2 and the third glass panel 3 and outside the sealing strip 7, a transparent conductive electrode 11 and a photosensitive element 12 are arranged on the surface of the second glass panel 2 facing the first glass panel 1, and a thermosensitive element 13 is arranged on the inner surface of the third glass panel 3.

[0020] The first glass panel 1, the second glass panel 2 and the third glass panel 3 serve as carriers of the electrochromic layer 4 and the thermochromic material layer 6, and simultaneously form support for the entire glass. Arranging three glass panels can increase the strength of the glass.

[0021] The photosensitive element 12 is used to detect the intensity of ambient light, and then transmits the light intensity signal to the processor, which then transmits the signal to the transparent conductive electrode 11 to adjust its voltage, and finally adjusts the color and brightness of the electrochromic layer 4. For example, when the external light is strong, the glass can become darker to reduce reflection and glare.

[0022] The thermochromic material layer 6 changes color when the temperature changes, and the thermosensitive element 13 can detect the temperature of the thermochromic material layer 6 .

[0023] The color and brightness of the glass can be adjusted by the cooperation of the electrochromic layer 4 and the thermochromic material layer 6 .

[0024] The PVB isolation layer 5 is bonded between the first glass panel 1 and the second glass panel 2 to prevent the electrochromic layer 4 and the thermochromic material layer 6 from interfering with each other.

[0025] The sealant 10 is used to connect the second glass panel 2 and the third glass panel 3 , and is also used to install the sealing strip 7 .

[0026] Specifically, if Figure 2 As shown, the sealing strip 7 is made of aluminum, and a heating wire installation groove 701 is provided on the inner surface of the sealing strip 7 . A heating wire fixing structure 9 and a heating wire 8 are installed in the heating wire installation groove 701 . The heating wire fixing structure 9 is sleeved on the outer side of the heating wire 8 .

[0027] The heating wire 8 generates heat after being energized, which can effectively treat ice, snow or fog on the glass surface, and at the same time can change the color of the thermochromic material layer 6, thereby realizing the function of actively adjusting the color.

[0028] The heating wire 8 is installed in the heating wire installation groove 701 through multiple groups of heating wire fixing structures 9.

[0029] Specifically, if Figure 2 As shown, the heating wire fixing structure 9 includes a mounting block 901 and an insulating layer 902. Grooves are symmetrically provided on the inner surfaces of the two mounting blocks 901. The insulating layer 902 is a semi-cylindrical structure, and the insulating layer 902 is assembled in the groove. The heating wire 8 is arranged between the two insulating layers 902, and the mounting block 901 is welded and assembled in the heating wire mounting groove 701.

[0030] Each set of heating wire fixing structures 9 includes two mounting blocks 901 and two insulating layers 902. The mounting blocks 901 are installed in the heating wire mounting groove 701 by welding to fix the heating wire 8 in the heating wire mounting groove 701 so that the heating wire 8 will not be exposed to the outside to avoid affecting the visual appearance of the glass. The insulating layer 902 plays an insulating role and supports and protects the heating wire 8 at the same time.

[0031] Specifically, the electrochromic layer 4 is tungsten oxide.

[0032] Specifically, the thermochromic material layer 6 is liquid crystal or polymer dispersed liquid crystal.

[0033] Specifically, the transparent conductive electrode 11 is made of tin oxide or silver nanowires.

[0034] Specifically, the photosensitive element 12 is a photoresistor or a photodiode.

[0035] The heat sensitive element 13 may be a thermistor.

[0036] Specifically, if Figure 1 As shown, the outer surfaces of the first glass panel 1 and the third glass panel 3 are both provided with an anti-splash layer 14 .

[0037] The anti-splash layer 14 is an anti-splash film, which is adhered to the outer surfaces of the first glass panel 1 and the third glass panel 3 by a film, and has the performance of anti-scratch and anti-wear, thereby increasing the safety of the glass.

[0038] When installed and used, this electrochromic glass with environmental adaptability is connected to an external processor and a power supply through a driving circuit. The transparent conductive electrode 11, the photosensitive element 12, and the thermosensitive element 13 are all connected to the processor. The photosensitive element 12 detects the ambient light intensity signal and transmits it to the processor. Then the processor controls the voltage of the transparent conductive electrode 11 to achieve the color change of the electrochromic layer 4. In addition, the voltage of the transparent conductive electrode 11 can also be actively adjusted to change the color of the electrochromic layer 4. The thermosensitive element 13 can measure the temperature and transmit the temperature information to the processor. The processor can be externally connected to an input device and a display device to facilitate user observation and operation.

[0039] Among them, the driving circuit includes functions such as signal processing, amplification, filtering, overheat protection, and short-circuit protection, which completes its own work while ensuring stable and safe operation.

[0040] This environmentally adaptable electrochromic glass can be applied in different fields. In the construction field, it can be used to adjust indoor light, save energy and improve comfort; in the automotive field, it can be used to adjust the driver's line of sight and improve driving safety; in addition, it can also be used in smart homes, smart offices and other fields to provide convenience for realizing smart life.

[0041] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
