[0020] The detailed description of the present disclosure is described in detail below with reference to the accompanying drawings. It should be understood that the detailed description described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0021] In the prior art, the variable color glass usually only includes a single variable color film layer, and the variable color glass can only realize a single rate of light transmittance change, which cannot meet the diversified variable color scene requirements and is expensive to use.

[0022] Therefore, the present disclosure provides a variable color glass. FIG. 1 is a structural block diagram of a variable color glass 100 according to an exemplary embodiment. As shown in FIG. 1, the variable color glass 100 includes multiple variable color film layers 120 and multiple glass layers 110, and each variable color film layer 120 is arranged between any two glass layers 110.

[0023] It is worth mentioning that the color-changing film layer is arranged in the interior or interlayer of the color-changing glass 100 to avoid performance degradation caused by external environmental factors and effectively prolong the service life of the color-changing film layer.

[0024] In an embodiment, the color-changing glass 100 can be applied to the vehicle window glass, and the color-changing glass 100 can be at least one of the front windshield, the rear windshield, the left window glass, the right window glass, and the sunroof glass of the vehicle.

[0025] The plurality of color-changing film layers 120 include a first color-changing film layer and a second color-changing film layer with different color-changing rates.

[0026] In an embodiment, different color-changing film layers 120 use different color-changing materials, so that different color-changing film layers 120 have different color-changing rates due to at least one of different oxidation-reduction rates, ion conductivity of electrolyte, catalytic properties of electrode materials, and voltage and current limitations.

[0027] The color-changing rate of the first color-changing film layer of the color-changing glass 100 is greater than that of the second color-changing film layer. When the vehicle is in driving state, if the window glass is irradiated by strong light, the first color-changing film layer can be controlled to change color to achieve the requirement of rapid color change of the window glass, avoid the strong light from interfering with the driver's vision, and thus ensure the comfort of the vehicle interior and the driving safety of the driver. When the vehicle is in parking state, if the vehicle glass is irradiated by strong light or subjected to a manual adjustment instruction from the user, the second color-changing film layer can be controlled to change color to achieve slow color change of the window glass. The color change of the window glass when the vehicle is parked can protect the privacy inside the vehicle and prevent damage to the vehicle interior due to exposure to sunlight. At the same time, using the second color-changing film layer with a slower color-changing rate can reduce the use cost of the color-changing film layer, thereby improving the practical value.

[0028] According to the plurality of color-changing film layers with different color-changing rates, the light transmittance of the color-changing glass can be rapidly or slowly adjusted to adapt to different environmental conditions and user preferences, and the use cost of the color-changing glass can be effectively reduced to improve the economy of use.

[0029] Optionally, FIG. 2 is a structural block diagram of a color-changing glass 100 according to an exemplary embodiment. As shown in FIG. 2, the plurality of glass layers include a first glass layer 111, a second glass layer 112, and a third glass layer 113.

[0030] The first color-changing film layer 121 is located between the first glass layer 111 and the second glass layer 112, and the second color-changing film layer 122 is located between the second glass layer 112 and the third glass layer 113.

[0031] It is worth noting that the second glass layer 112 can be referred to as an intermediate glass layer. The intermediate glass layer can be arranged between any two color-changing film layers 120 to avoid interference between the two color-changing film layers 120. For example, when the color-changing film layers 120 are controlled to change color by an electrical signal, the first color-changing film layer 121 and the second color-changing film layer 122 are separated by the intermediate glass layer. This can prevent the other color-changing film layer 120 from changing color when one of the color-changing film layers 120 is controlled to change color, resulting in an uncontrolled color-changing range of the color-changing glass. By controlling each color-changing film layer 120 to change color independently, the color-changing glass can meet the color-changing needs of various application scenarios and improve the accuracy of color-changing control.

[0032] Optionally, the first color-changing film layer 121 and the second color-changing film layer 122 are both electrochromic film layers.

[0033] It is worth noting that the electrochromic film layer is an electrochromic material, such as a transition metal oxide. When the electrochromic film layer is subjected to a voltage, the material undergoes an oxidation-reduction reaction. In the oxidized state, the material has a darker color and a lower light transmittance. In the reduced state, the material has a lighter color and a higher light transmittance.

[0034] The oxidation-reduction of the electrochromic material is reversible. Therefore, by adjusting the polarity and magnitude of the voltage applied to the electrochromic film layer, the color and light transmittance of the electrochromic film layer can be controlled.

[0035] Optionally, the first color-changing film layer 121 includes a first electrode, and the second color-changing film layer 122 includes a second electrode. The catalytic activity of the first electrode and the second electrode is different.

[0036] Optionally, the ion conductivity of the electrolyte in the first color-changing film layer 121 and the second color-changing film layer 122 is different.

[0037] In an embodiment, the color-changing rate of the color-changing film layer 120 is related to the voltage corresponding to the electrical signal applied to the color-changing film layer 120. Within a predetermined voltage range, the higher the voltage, the faster the color-changing rate of the color-changing film layer 120. The color-changing rate of the color-changing film layer 120 is also related to the color-changing material itself. For example, the difference in chemical structure of the color-changing material itself can affect the oxidation-reduction rate. The color-changing film layer 120 with a slower color-changing rate can have a thicker film layer or a more complex structure, resulting in an increase in ion diffusion distance during oxidation-reduction, which in turn slows down the color-changing rate. In addition, the difference in ion conductivity of the electrolyte or the difference in catalytic activity of the electrode in the color-changing film layer 120 can also affect the oxidation-reduction rate and thus the color-changing rate. That is, by adjusting the chemical structure of the color-changing material, the electrolyte, and the electrode in the color-changing film layer 120, the corresponding use requirements can be met.

[0038] Optionally, the variable-tint glass 100 is a variable-tint glass for a vehicle, the first variable-tint film layer 121 has a variable-tint rate greater than that of the second variable-tint film layer 122, the first variable-tint film layer 121 is configured to adjust the light transmittance when the vehicle is in a driving state, and the second variable-tint film layer 122 is configured to adjust the light transmittance when the vehicle is in a parking state.

[0039] FIG. 3 is a structural block diagram of a variable-tint control system 10 according to an exemplary embodiment. As shown in FIG. 3, the variable-tint control system 10 is applied to a vehicle and includes a controller 200, a photosensitive sensor 300, and a variable-tint glass 100.

[0040] The variable-tint glass 100 includes a plurality of variable-tint film layers 120 and a plurality of glass layers 110, each of the variable-tint film layers 120 is arranged between any two of the glass layers 110, wherein the plurality of variable-tint film layers 120 includes a first variable-tint film layer 121 and a second variable-tint film layer 122 having different variable-tint rates, and the first variable-tint film layer 121 and the second variable-tint film layer 122 are both electrochromic film layers.

[0041] The photosensitive sensor 300, the first variable-tint film layer 121, and the second variable-tint film layer 122 are all connected to the controller 200.

[0042] The photosensitive sensor 300 is configured to detect the light intensity received by the variable-tint glass 100, i.e., to obtain ambient light intensity information.

[0043] In an embodiment, the vehicle has variable-tint glass 100 for each window, the photosensitive sensor 300 detects the light intensity received by each window in real time and sends corresponding ambient light intensity information to the controller 200, the controller 200 determines whether the light intensity received by each window exceeds a preset light intensity threshold based on the received ambient light intensity information, and if so, the controller 200 controls the variable-tint glass 100 to change tint according to the preset light transmittance corresponding to the light intensity received by the variable-tint glass 100.

[0044] Optionally, as shown in FIG. 3, the variable-tint control system 10 further includes a wheel speed sensor 400, and the wheel speed sensor 400 is connected to the controller 200.

[0045] The wheel speed sensor 400 is configured to monitor wheel speed information and transmit the information to the microprocessor 230, the microprocessor 230 receives the wheel speed information and determines whether the vehicle is in a driving state or a parking state, and then sends the determination result to the main controller 210, and the main controller 210 controls the variable-tint film layers 120 to change tint according to the current state of the vehicle through different variable-tint controllers.

[0046] In combination with the device in the foregoing embodiments, based on the wheel speed sensor 400, different control can be performed on the variable color glass 100 in different states to meet the current shading scene.

[0047] FIG. 4 is a schematic diagram of a connection between a variable color controller and a variable color film layer according to an exemplary embodiment. As shown in FIG. 4, the controller 200 includes a plurality of variable color controllers 220.

[0048] The parking variable color controller 222 in the plurality of variable color controllers 220 is connected with the second variable color film layer 122 in the variable color glass 100.

[0049] The driving variable color controller 221 in the plurality of variable color controllers 220 is connected with the first variable color film layer 121 in the variable color glass 100.

[0050] In an embodiment, the parking variable color controller 222 is used to control the second variable color film layer 122 in the variable color glass 100 to change color when the vehicle is in a parking state, i.e., to control the variable color glass 100 to change color slowly, and the driving variable color controller 221 is used to control the first variable color film layer 121 in the variable color glass 100 to change color when the vehicle is in a driving state, i.e., to control the variable color glass 100 to change color quickly.

[0051] For example, the driving variable color controller 221 is an automatic variable color controller that automatically controls the variable color glass 100 to change color when the vehicle is in a driving state, i.e., without the need for a user to manually input an operation instruction, and the parking variable color controller 222 is a manual variable color controller that requires a user to manually input an operation instruction through a control panel of the vehicle.

[0052] The variable color glass 100 is controlled by the driving variable color controller 221 to change color quickly when driving, thereby improving the driving comfort and safety of the driver, and the variable color glass 100 is controlled by the parking variable color controller 222 to change color slowly when parking, thereby effectively reducing the use cost of the variable color glass and improving the economy.

[0053] FIG. 5 is a flowchart of a control method of a variable color glass according to an exemplary embodiment. As shown in FIG. 5, the variable color glass 100 can be controlled by the following steps.

[0054] First, the wheel speed sensor 400 collects wheel speed information of the vehicle in real time and sends the wheel speed information to the microprocessor 230.

[0055] Second, the microprocessor 230 determines whether the vehicle is in a driving state or a parking state according to the received wheel speed information.

[0056] For example, when the wheel speed information represents that the wheel speed of the vehicle is greater than 0 RPM (Revolutions Per Minute), the microprocessor 230 determines that the vehicle is in a driving state, and when the wheel speed information represents that the wheel speed of the vehicle is equal to 0 RPM, the microprocessor 230 determines that the vehicle is in a parking state.

[0057] If the vehicle is in the driving state, the third step is performed, and if the vehicle is in the parking state, the sixth step is performed.

[0058] In the third step, the main controller 210 receives the ambient light intensity information obtained by the photosensitive sensor 300, and determines the light environment state in which the vehicle is currently located.

[0059] For example, if the ambient light intensity information represents that the light intensity received by the vehicle is greater than a preset daylight intensity threshold and greater than the preset daylight intensity threshold for a first preset time length, it is determined that the light environment state of the vehicle is a daytime driving state, i.e., the light type received by the variable tint glass is natural light, and the fourth step is performed.

[0060] If the ambient light intensity information represents that the light intensity received by the vehicle is less than or equal to the preset daylight intensity threshold and less than or equal to the preset daylight intensity threshold for a second preset time length, it is determined that the light environment state of the vehicle is a nighttime driving state, i.e., the light type received by the variable tint glass is non-natural light, and the fifth step is performed.

[0061] The natural light can be sunlight, and the non-natural light can be light emitted by high beams of other vehicles.

[0062] In the fourth step, when the vehicle is in the daytime driving state, the light intensity of the light received by the variable tint glass 100 of the vehicle is monitored in real time. If the light intensity is greater than a first light intensity threshold, the first variable tint film layer 121 is controlled to change color by the driving variable tint controller 221 according to the target light transmittance corresponding to the current light intensity within a preset first variable tint range. If the light intensity is less than or equal to the first light intensity threshold, the variable tint glass 100 is not controlled to change color.

[0063] After the fourth step is completed, the first step is returned.

[0064] In the fifth step, when the vehicle is in the nighttime driving state, the light intensity of the light received by the variable tint glass 100 of the vehicle is monitored in real time. If the light intensity is greater than a second light intensity threshold, the first variable tint film layer 121 is controlled to change color by the driving variable tint controller 221 according to the target light transmittance corresponding to the current light intensity within a preset second variable tint range. If the light intensity is less than or equal to the second light intensity threshold, the variable tint glass 100 is not controlled to change color.

[0065] After the fifth step is completed, the first step is returned.

[0066] It is worth mentioning that for the same light intensity, the target color change degree corresponding to the preset natural light color change range is greater than the target color change degree corresponding to the preset non-natural light color change range.

[0067] In an embodiment, to ensure the material cost and long-term stability of the color change control system 10, the color change control is usually performed only on the front windshield glass of the vehicle when the vehicle is in driving state.

[0068] In the sixth step, the main controller 210 receives the operation instruction sent by the user control panel, and controls the color change of the color change glass 100 of the vehicle through the parking color change controller 230 according to the operation instruction, and returns to the first step after completing the sixth step.

[0069] In the sixth step, the main controller 210 receives the operation instruction sent by the user control panel, and controls the color change of the color change glass 100 of the vehicle through the parking color change controller 230 according to the operation instruction, and returns to the first step after completing the sixth step.

[0070] Optionally, the controller 200 comprises a plurality of color change controllers.

[0071] Referring to FIG. 4, the first color change controller 2201 and the second color change controller 2202 in the plurality of color change controllers 220 are connected with the first color change film layer 121, and the electrical signal output by the first color change controller 2201 to the first color change film layer 121 is different from the electrical signal output by the second color change controller 2202 to the first color change film layer 121, so that the first color change controller 2201 and the second color change controller 2202 can control the first color change film layer 121 to have different light transmittances.

[0072] In an embodiment, the first color-changing controller 221 and the second color-changing controller 222 are integrated in the driving color-changing controller 220, the first color-changing controller 221 is a daylight color-changing controller, the second color-changing controller 222 is a high beam color-changing controller, the first color-changing controller 221 and the second color-changing controller 222 are electrically connected to the first color-changing film layer 121 of the color-changing glass 100, and the first color-changing controller 221 and the second color-changing controller 222 output different electrical signals to the first color-changing film layer 121 so that the first color-changing film layer 121 performs different degrees of redox reaction and has different light transmittances. The voltage corresponding to the electrical signal output by the first color-changing controller 221 is less than the voltage corresponding to the electrical signal output by the second color-changing controller 222, that is, when the first color-changing controller 221 controls the first color-changing film layer 121 to change color, the light transmittance of the first color-changing film layer 121 is lower, so that the light transmittance of the color-changing glass 100 can be quickly and widely adjusted during daytime driving, preventing direct sunlight from shining into the driver's eyes. When the second color-changing controller 222 controls the first color-changing film layer 121 to change color, the light transmittance of the first color-changing film layer 121 is higher, so that the light transmittance of the color-changing glass 100 can be quickly and small-range adjusted during nighttime driving, thereby preventing the high beam from shining into the driver's eyes without affecting the field of view.

[0073] In another embodiment, the third color-changing controller and the fourth color-changing controller can also be integrated in the parking color-changing controller 230, the third color-changing controller is a daylight color-changing controller, the fourth color-changing controller is a high beam color-changing controller, and the third color-changing controller and the fourth color-changing controller are electrically connected to the second color-changing film layer 122 of the color-changing glass 100, so that when the vehicle is in a parking state, the light transmittance of the color-changing glass 100 can also be automatically and slowly adjusted.
