[0002] In the field of electrochromic device technology, electrochromic materials possess bistable properties. By placing the material in different electronic states, a reversible redox reaction occurs under electrochemical action, causing changes in the material's optical properties. Externally, this manifests as the material's color cyclically changing with voltage, alternating between a transparent and colored state, thus altering the light transmittance. Therefore, electrochromic materials, as one of the most promising smart materials currently available, possess enormous potential application prospects and commercial value due to their excellent electrical, optical, and electrochromic properties.

[0003] Currently, the most common application of electrochromic materials is in electrochromic windows. Electrochromic windows control the amount of light incident by adjusting the light transmittance of the electrochromic material, which can conveniently control the amount of incident light inside a building to achieve the purpose of light regulation and energy saving. However, the existing electrochromic window adjustment modes are relatively simple and cannot achieve a balance between heat insulation and light blocking. Summary of the Invention

[0004] The purpose of this invention is to provide an electrochromic smart window and its color-changing control method to solve the above-mentioned problems, so as to achieve intelligent adjustment of the light transmission and heat transmission performance of electrochromic glass and realize the purpose of automatically regulating the light and heat entering the room.

[0005] To achieve the above objectives, the present invention provides the following solution: an electrochromic smart window, comprising:

[0006] A window frame, wherein a middle partition frame is fixedly connected inside the window frame;

[0007] Two sets of glass bodies are respectively disposed within the window frame, and the middle partition frame is located between the two sets of glass bodies. Each glass body includes two sets of conductive glass, and a gel electrolyte is sandwiched between the two sets of conductive glass and the window frame and the middle partition frame. Electrochromic films are respectively disposed on the opposite sidewalls of the two sets of conductive glass.

[0008] Two sets of glass are located on both sides of the middle partition frame, and an air cavity is provided between the glass and the conductive glass, the window frame, and the middle partition frame;

[0009] An airflow control assembly includes a plurality of second openings respectively formed on two opposite sidewalls of the intermediate partition frame, the second openings communicating with the air cavity, and a communication control mechanism provided in the intermediate partition frame, the communication control mechanism being used to control whether the plurality of second openings are connected or not.

[0011] Preferably, the control unit includes a light sensor disposed on the window frame, the light sensor being disposed on the side of the window frame away from the interior of the house.

[0012] Preferably, the control unit further includes a temperature sensor disposed within the air cavity.

[0013] Preferably, the control unit adjusts the light transmittance and heat transmittance properties of the electrochromic film by adjusting the voltage applied to the glass body.

[0014] Preferably, the control unit controls the voltage applied to the glass body to three levels: 1V, -0.2V, and -1V.

[0015] Preferably, the communication control mechanism includes a sliding groove formed within the intermediate partition frame, a plurality of second openings on the two opposite sidewalls of the intermediate partition frame communicating with the sliding groove, a sliding plate slidably connected within the sliding groove, a plurality of first openings formed on the sliding plate, a position adjustment component provided between the intermediate partition frame and the sliding plate, the position adjustment component being used to drive the sliding plate to slide in the sliding groove, and when the sliding plate slides to the point where the first openings coincide with the second openings on both sides of the intermediate partition frame, the air cavities on both sides of the intermediate partition frame are connected.

[0017] A method for controlling an electrochromic smart window, the control process including:

[0018] Based on external light intensity and temperature factors, when the external ambient temperature is high and the light intensity is strong, the control unit controls the two sets of glass bodies to be in a state of strong light transmission and heat transmission.

[0019] When the external ambient temperature is low and the light intensity is weak, the control unit controls the two sets of glass bodies to be in a state of weak light transmittance and heat transmittance.

[0020] When the external ambient temperature is low but the sunlight is strong, the control unit controls the electrochromic film on the outer side of one set of glass bodies to be in a state of strong light and heat transmission, while controlling the remaining glass bodies to be in a state of weak light and heat transmission, thereby minimizing the irradiation of strong light.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1:

[0035] Reference Figures 1-4 The present invention provides an electrochromic smart window, comprising:

[0036] Window frame 4, with a middle partition frame 7 fixedly connected inside the window frame 4;

[0037] Two sets of glass bodies 1 are respectively set inside the window frame 4, and the middle partition 7 is located between the two sets of glass bodies 1. The glass body 1 includes two sets of conductive glass 11. A gel electrolyte 24 is sandwiched between the two sets of conductive glass 11, the window frame 4, and the middle partition 7. Electrochromic films 12 are respectively provided on the opposite side walls of the two sets of conductive glass 11.

[0038] Two sets of glass 25 are located on both sides of the middle partition frame 7. An air cavity 3 is provided between the glass 25 and the conductive glass 11, the window frame 4, and the middle partition frame 7.

[0039] An airflow control assembly includes a plurality of second openings 17 respectively opened on two opposite sidewalls of a middle partition frame 7. The second openings 17 are connected to an air cavity 3. A connection control mechanism is provided in the middle partition frame 7. The connection control mechanism is used to control whether the plurality of second openings 17 are connected or not.

[0040] The control unit is located on the window frame 4. The control unit is used to adjust the light transmission and heat transmission performance of the glass body 1 and to operate the communication control mechanism.

[0041] The main function of the middle partition 7 is to divide the window frame 4 into two areas, allowing for different adjustment methods for the glass bodies 1 in the upper and lower areas. The glass body 1 is an integral device formed by conductive glass 11, electrochromic film 12, and gel electrolyte 24. By receiving different voltages, the light transmittance and heat transmittance of the electrochromic film 12 are changed. In this embodiment, a total of four sets of glass bodies 1 are provided, which can be adjusted in various combinations. The main function of the air cavity 3 is to improve the heat insulation capability of the smart window of the present invention. At the same time, by changing the temperature of the air in the air cavity 3, it plays a role in assisting in regulating the indoor temperature. Meanwhile, the two sets of conductive glass 11 and one set of glass 25 form a three-layer structure, which can improve the sound insulation capability of the smart window of the present invention to a certain extent. The main function of the second opening 17 is to realize the air flow in the air cavities 3 on both sides of the middle partition 7. The main function of the connecting control mechanism is to control the air flow between the two air cavities 3. Overall, this invention can intelligently adjust the light transmittance and heat transmittance of electrochromic glass through a control unit. At the same time, by changing the light transmittance and heat transmittance of different glass bodies, the air temperature in the air cavity can be adjusted, thereby achieving the purpose of automatically controlling the light and heat entering the room.

[0042] Further optimization of the design resulted in the use of ordinary glass for Glass 25.

[0043] Specifically, in this embodiment, the preparation method of the electrochromic film 12 is as follows: First, a tungsten source, hydrogen peroxide solution, inorganic acid and water are mixed to obtain an electrodeposition solution; then, using conductive glass as the working electrode, a tungsten oxide film is deposited on the conductive glass 11 by pulsed electrochemical deposition, thereby obtaining a porous tungsten oxide film that can independently control visible light and near-infrared light, thus forming an electrochromic film 12 on the surface of the conductive glass 11.

[0044] The control unit is further optimized by including a light sensor 6 installed on the window frame 4, with the light sensor 6 located on the side of the window frame 4 away from the interior of the house.

[0045] like Figure 1 As shown, the light sensor 6 is installed outdoors to monitor the outdoor light intensity.

[0046] To further optimize the design, the control unit also includes a temperature sensor 5 located inside the air cavity 3.

[0047] The main function of temperature sensor 5 is to monitor the air temperature in air cavity 3.

[0048] The scheme was further optimized so that the control unit adjusted the light transmittance and heat transmittance performance of the electrochromic film 12 by adjusting the voltage applied to the glass body 1.

[0049] Further optimization of the scheme involves setting the voltage applied to the glass body 1 to three levels: 1V, -0.2V, and -1V, controlled by the control unit.

[0050] The solution was further optimized so that the control unit, light sensor 6, and temperature sensor 5 are powered by household electricity.

[0051] When a voltage of 1V is applied to the glass body 1 prepared according to the aforementioned method, the electrochromic film 12 is in a faded state, exhibiting high transmittance to visible and near-infrared light, and strong light and heat transmission. When a voltage of -1V is applied, the electrochromic film 12 is in a colored state, exhibiting high blocking rate to visible and near-infrared light, and poor light and heat transmission. When a voltage of -0.2V is applied, the electrochromic film 12 exhibits high transmittance to visible light and high blocking rate to near-infrared light. At this time, it has strong light transmission and poor heat transmission, which can insulate heat while allowing light to shine into the room.

[0052] The scheme is further optimized. The communication control mechanism includes a slide groove 14 opened in the middle partition frame 7. Several second openings 17 on the two opposite side walls of the middle partition frame 7 are respectively connected to the slide groove 14. A sliding plate 15 is slidably connected in the slide groove 14. Several first openings 16 are opened on the sliding plate 15. A position adjustment component is provided between the middle partition frame 7 and the sliding plate 15. The position adjustment component is used to drive the sliding plate 15 to slide in the slide groove 14. When the sliding plate 15 slides to the point where the first openings 16 coincide with the second openings 17 on both sides of the middle partition frame 7, the air cavities 3 on both sides of the middle partition frame 7 are connected.

[0053] like Figure 3 and Figure 4 As shown, the spacing between two adjacent second openings 17 at the top of the middle partition frame 7, between two adjacent second openings 17 at the bottom of the middle partition frame 7, and between two adjacent first openings 16 are all the same, and the spacing distance must be greater than the length of the first opening 16. When it is necessary to connect the air cavities 3 on the upper and lower sides of the middle partition frame 7, the sliding plate 15 can be pulled by the position adjustment component to make the first opening 16 on the sliding plate 15 gradually overlap with the second opening 17, so that the air in the lower air cavity 3 can enter the upper air cavity 3 in sequence through the second opening 17 at the bottom of the middle partition frame 7, the first opening 16, and the second opening 17 at the top of the middle partition frame 7. As the overlapping area between the first opening 16 and the second opening 17 increases, the flow efficiency also increases.

[0054] Further optimization of the scheme: the position adjustment component includes a servo motor 9 fixedly connected in the middle partition frame 7, a lead screw 10 fixedly connected coaxially to the output shaft of the servo motor 9, the axis direction of the lead screw 10 being parallel to the sliding direction of the sliding plate 15, and a threaded sleeve 13 fixedly connected to the side of the sliding plate 15 near the servo motor 9, the threaded sleeve 13 being connected to the lead screw 10 in a transmission connection.

[0055] like Figure 4 As shown, the control unit is electrically connected to the servo motor 9. When airflow between the upper and lower air cavities 3 is required, the control unit controls the servo motor 9 to rotate. The rotation of the servo motor 9 drives the lead screw 10 to rotate synchronously. When the lead screw 10 rotates, it drives the threaded sleeve 13 to move closer to the sliding plate 15 through threaded transmission, causing the first opening 16 to shift to the left and coincide with the second opening 17. When it is not necessary to connect the upper and lower air cavities 3, the control unit controls the servo motor 9 to reverse, causing the sliding plate 15 to slide in the opposite direction, causing the first opening 16 to be misaligned with the second opening 17 until it is positioned between the two second openings 17, whereby the sliding plate 15 blocks the second opening 17.

[0056] A method for controlling an electrochromic smart window, the control process including:

[0057] Based on external light intensity and temperature factors, when the external ambient temperature is high and the light intensity is strong, the control unit controls the two sets of glass bodies 1 to be in a state of strong light transmission and heat transmission.

[0058] When the external ambient temperature is high and the light intensity is strong, the control unit applies a voltage of -1V to all four glass bodies 1, causing all electrochromic films 12 to be in a color-changing state. This ensures that the electrochromic films 12 have strong blocking properties for both visible and near-infrared light, preventing the indoor environment from becoming too bright and hot. In summer, when the light sensor 6 detects a decrease in light intensity, but the temperature sensor 5 detects a high temperature in the air cavity 3, the control unit applies a voltage of -0.2V to all four glass bodies 1. This allows the electrochromic films 12 to have high light transmittance while effectively blocking near-infrared light, increasing indoor brightness without allowing excessive heat to enter.

[0059] When the external ambient temperature is low and the light intensity is weak, the control unit controls the two sets of glass bodies 1 to be in a state of weak light transmittance and heat transmittance.

[0060] When the external ambient temperature is low and the light intensity is weak, the control unit applies a voltage of 1V to all four glass bodies 1, causing all electrochromic films 12 to be in a faded state, so that the electrochromic films 12 have strong transmittance to visible light and near infrared light, thus avoiding the indoor environment being too dark and the temperature too low.

[0061] When the external ambient temperature is low but the sunlight is strong, the control unit controls the electrochromic film 12 on the outer side of a set of glass bodies 1 to be in a state of strong light transmission and heat transmission, while controlling the remaining glass bodies 1 to be in a state of weak light transmission and heat transmission, thereby minimizing the irradiation of strong light. At the same time, sunlight passes through the glass bodies 1 in a state of strong light transmission and heat transmission to heat the air cavity 3. Simultaneously, the control unit drives the connecting control mechanism to connect the air cavities 3 on both sides of the middle partition frame 7, and the air flow causes the internal air of the two air cavities 3 to heat up, thus providing a heat preservation effect for the room.

[0062] In winter, snow reflects light, making the outdoor light intensity quite strong. At this time, the light sensor 6 detects strong light, but the temperature sensor 5 detects a low temperature in the air cavity 3, indicating a low outside temperature. Therefore, it's necessary to block some visible light while allowing near-infrared light to pass through. Simultaneously, the control unit applies a 1V voltage to the glass body 1 below the middle partition frame 7, causing it to fade. Near-infrared light then irradiates and heats the air in the air cavity 3. At the same time, the control unit applies a -1V voltage to the remaining conductive glass 11, causing it to fully display its color. This effectively blocks external visible light, preventing a large amount of intense light from entering.

[0063] As the air temperature in the lower air cavity 3 rises, the control unit controls the sliding plate 15 to move via the servo motor 9, connecting the first opening 16 and the second opening 17, allowing air to flow between the upper and lower air cavities 3, thus raising the temperature in the air cavity 3 and consequently increasing the temperature of the glass body 1, preventing an excessive drop in indoor temperature.

[0064] Example 2:

[0065] like Figures 5-8 As shown, the only difference between this embodiment and Embodiment 1 is that an opening and closing window frame 8 is also provided on the window frame 4, and the glass body 1 in Embodiment 1 is also installed on the opening and closing window frame 8.

[0066] Since the external environment is directly connected to the indoor environment when the window frame 8 is opened, the glass body 1 on the window frame 8 no longer needs to change color. Therefore, an electrode connection assembly is also provided between the window frame 8 and the window frame 4.

[0067] The solution is further optimized. The electrode connection assembly includes pole posts 18 fixedly connected to the top and bottom of the side wall of the opening and closing window frame 8. Two sets of pole posts 18 are set close to the window frame 4. Two sets of electrode grooves 20 are opened on the side of the window frame 4 close to the opening and closing window frame 8. The two sets of electrode grooves 20 are correspondingly set with the two sets of electrode posts 18. The pole posts 18 are electrically connected to the electrochromic film 12 inside the opening and closing window frame 8.

[0068] When the window frame 8 is opened, the electrode post 18 disengages from the electrode groove 20 as the window frame 8 moves. At this time, the glass body 1 stops changing color because it can no longer receive voltage.

[0069] In a further optimized design, a sliding groove is provided on the side of the window frame 8 near the window frame 4, and the pole post 18 is slidably connected in the sliding groove. An elastic plate 22 abuts against the bottom of the sliding groove at the end of the pole post 18 near the window frame 8.

[0070] When the window frame 8 is closed, the pole post 18 is inserted into the electrode groove 20. Under the pressure of the elastic plate 22, the pole post 18 will fit tightly with the electrode groove 20, avoiding poor contact between the pole post 18 and the electrode groove 20, and ensuring that the glass body 1 inside the window frame 8 can work normally after the window frame 8 is closed.

[0071] To further optimize the design, when the opening and closing window frame 8 is opened, in order to prevent a large amount of dust from entering the electrode post 18 and electrode groove 20 and causing poor contact, a corrugated sealing sleeve 19 is fixedly connected to the side wall of the opening and closing window frame 8. The electrode post 18 is located inside the corrugated sealing sleeve 19. At the same time, a sealing gasket 21 is fixedly connected to the opening of the electrode groove 20. The end of the corrugated sealing sleeve 19 away from the opening and closing window frame 8 is sealed and has a second cross-shaped crack 23. The sealing gasket 21 has a first cross-shaped crack 2.

[0072] like Figures 6-8 As shown, when the window frame 8 is closed, the corrugated sealing sleeve 19 is compressed. At the same time, the head of the pole post 18 passes through the second cross crack 23 and through the first cross crack 2 to contact the bottom of the electrode groove 20, thus achieving an electrical connection between the two.

[0073] When the window frame 8 is opened, the corrugated sealing sleeve 19 returns to its extended state, and the second cross crack 23 returns to its closed state under its own elasticity, sealing the pole 18 in the corrugated sealing sleeve 19. At the same time, the first cross crack 2 returns to its closed state under the elasticity of the sealing gasket 21, sealing the electrode groove 20 and preventing dust from entering.

[0074] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0075] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
