Specifically, the outer frame 10 is a transparent box body made of tempered glass, a rubber ring 21 for protecting the first glass substrate 11 and the second glass substrate 12 is arranged in the outer frame 10, the first glass substrate 11 and the second glass substrate 12 are both made of tempered glass, and a frame lock 20 for opening and closing the outer frame is further arranged on the outer frame 10.

Preferably, the electrochromic layer 18 is provided with a second insulating layer 19, the ion storage layer 14 is provided with a first insulating layer 15, the first insulating layer 15 and the second insulating layer 19 are respectively arranged along the peripheral direction of the edges of the electrochromic layer 18 and the ion storage layer 14, the width of the first insulating layer 15 and the second insulating layer 19 is 2-5mm, and the thickness of the first insulating layer 15 and the second insulating layer 19 is 200-500 um.

Specifically, the electrolyte injection port 161 and the electrolyte discharge port 162 are provided at both ends of the electrolyte layer 16, respectively, and the electrolyte is one or more of lithium perchlorate and sodium perchlorate.

Specifically, metal films are coated on the first conductive film layer 13 and the second conductive film layer 17, a first power-on port 131 is arranged on the metal film of the first conductive film layer 13, a second power-on port 171 is arranged on the metal film of the second conductive film layer 17, and a positive-negative adjustable power supply 22 with a power supply voltage of 2-10V is arranged on the outer frame 10 and used for connecting the first power-on port 131 and the second power-on port 171.

In the embodiment, an indium tin oxide target is selected to plate a second conductive film layer 17 on a first glass substrate 11, a first conductive film layer 13 is plated on a second glass substrate 12, the film plating mode adopts vacuum coating or sputtering coating, a tungsten oxide electrochromic layer 18 is plated on the first conductive film layer 13 by adopting a dip-coating or thermal evaporation method, the thickness is 500nm, and a nickel oxide ion storage layer 14 is plated on the second conductive film layer 17 by adopting a sol-gel method, the thickness is 300 nm; the electrochromic layer 18 and the ion storage layer 14 are coated with a second insulating layer 19 and a first insulating layer 15, respectively, having a width of 3mm and a thickness of 400 um.

The working principle is as follows: under the action of an external electric field, tungsten oxide undergoes redox electrochemical reaction to obtain lost electrons, so that the color of the material is changed. When the electrochromic intelligent window works, voltage is applied between the first conductive film layer 13 and the second conductive film layer 17, and the color changes; when the electrolyte layer 16 is made of a solution of a special conductive material, such as lithium perchlorate or sodium perchlorate, the ion storage layer 14 stores counter ions during the oxidation-reduction reaction of tungsten oxide, thereby maintaining the charge balance of the system. Under the conventional condition, the electrochromic glass is in a transparent colorless state, and when voltage is applied, ions of the ion storage layer and electrons of the electrode are obtained to generate color change. When a reverse voltage is applied, electrons and ions are extracted, and return to the ion storage layer 14 through the original path, and then change back to the transparent tungsten oxide, thereby completing the color change cycle.

In addition, a series of control units, such as light energy power generation, a temperature control switch and the like, can be integrated in the outer frame 10, so that the smart window is more environment-friendly and efficient.
