[0031] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0032] In the existing technical solutions, the photochromic glass usually only includes a single photochromic film layer. The photochromic glass can only achieve a single rate of light transmittance change, cannot meet the needs of diverse photochromic scenes, and is expensive to use.
[0033] In view of this, the present disclosure provides a color-changing glass. Figure 1 is a structural block diagram of a color-changing glass 100 according to an exemplary embodiment. Figure 1 As shown, the color-changing glass 100 includes a plurality of color-changing film layers 120 and a plurality of glass layers 110 , and each of the color-changing film layers 120 is arranged between any two of the glass layers 110 .
[0034] It is worth noting that the color-changing film layer is arranged inside or in the interlayer of the color-changing glass 100 to avoid the performance degradation of the color-changing film layer caused by the influence of external environmental factors, and the service life of the color-changing film layer can be effectively delayed.
[0035] In one embodiment, the photochromic glass 100 can be applied to the window glass of a vehicle. The photochromic glass 100 can be at least one of the front windshield, rear windshield, left window, right window, and sunroof glass of the vehicle.
[0036] The plurality of color-changing film layers 120 include a first color-changing film layer and a second color-changing film layer having different color-changing rates.
[0037] In one 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 their redox rates, ion conductivity of the electrolyte, catalytic properties of the electrode material, and voltage and current limitations.
[0038] Among them, the color change rate of the first color change film layer of the photochromic glass 100 is greater than that of the second color change film layer. When the vehicle is in a driving state, if the window glass is exposed to strong light, the first color change film layer can be controlled to change color, so as to realize the window glass quickly affecting the color change demand and avoid the driver's vision being disturbed by strong light, thereby ensuring the comfort inside the vehicle and the driver's driving safety. When the vehicle is in a parking state, if the vehicle glass is exposed to strong light or receives a manual adjustment instruction from the user, the second color change film layer can be controlled to change color to realize the 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 the vehicle interior from being damaged due to exposure to the sun. At the same time, the use of a second color change film layer with a slower color change rate can reduce the use cost of the color change film layer to improve the practical value.
[0039] According to the multiple color-changing film layers with different color-changing rates, the light transmittance of the color-changing glass can be adjusted quickly or slowly to adapt to different environmental conditions and user preferences, and the use cost of the color-changing glass can be effectively reduced and the economy of use can be improved.
[0040] Optionally, Figure 2 is a structural block diagram of a color-changing glass 100 according to an exemplary embodiment. Figure 2 As shown, the plurality of glass layers include a first glass layer 111 , a second glass layer 112 and a third glass layer 113 .
[0041] 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 .
[0042] It is worth mentioning that the second glass layer 112 is called the intermediate glass layer. An intermediate glass layer is set between any two color-changing film layers 120 to avoid mutual interference between the two color-changing film layers 120. For example, when the color-changing film layer 120 is 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. This can avoid that when one of the color-changing film layers 120 is controlled to change color, the other color-changing film layer 120 is also correspondingly changed, resulting in an uncontrolled color change range of the color-changing glass. By controlling each color-changing film layer 120 to change color independently, the glass color change needs of various application scenarios can be met and the accuracy of color change control can be improved.
[0043] Optionally, both the first color-changing film layer 121 and the second color-changing film layer 122 are electrochromic film layers.
[0044] It is worth noting that the electrochromic film layer is an electrochromic material, for example, a metal oxide. When the electrochromic film layer is subjected to voltage, the material undergoes an oxidation-reduction reaction. In the oxidized state, the material has a darker color and a lower transmittance, and in the reduced state, the material has a lighter color and a higher transmittance.
[0045] Among them, the redox 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 transmittance changes of the electrochromic film layer can be controlled.
[0046] Optionally, the first color-changing film layer 121 includes a first electrode, the second color-changing film layer 122 includes a second electrode, and the first electrode and the second electrode have different catalytic activities.
[0047] The ion conductivity of the electrolyte in the first color-changing film layer 121 and the second color-changing film layer 122 is different.
[0048] In one 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 the preset voltage range, the higher the voltage, the faster the color changing rate of the color changing film layer 120, and 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 the chemical structure of the color changing material itself may affect the redox rate. The color changing film layer 120 with a slower color changing rate may have a thicker film layer or a more complex structure, resulting in an increase in the diffusion distance of ions during redox, which also leads to a slower color changing rate. In addition, the redox rate may be affected by the different ionic conductivity of the electrolyte in the color changing film layer 120 or the different catalytic activity of the electrode, thereby affecting the color changing rate. In other words, the chemical structure of the color changing material, the electrolyte and the electrode in the color changing film layer 120 are adjusted to meet the corresponding usage requirements.
[0049] Optionally, the photochromic glass 100 is a vehicle photochromic glass, the color change rate of the first photochromic film layer 121 is greater than the color change rate of the second photochromic film layer 122, the first photochromic film layer 121 is used to adjust the transmittance when the vehicle is in a driving state, and the second photochromic film layer 122 is used to adjust the transmittance when the vehicle is in a parking state.
[0050] Figure 3 is a structural block diagram of a color change control system 10 according to an exemplary embodiment, see Figure 3 As shown, the color changing control system 10 is applied to a vehicle, and includes: a controller 200 , a photosensitive sensor 300 and a color changing glass 100 .
[0051] The color-changing glass 100 includes a plurality of color-changing film layers 120 and a plurality of glass layers 110, wherein each of the color-changing film layers 120 is arranged between any two of the glass layers 110, wherein the plurality of color-changing film layers 120 include a first color-changing film layer 121 and a second color-changing film layer 122 with different color-changing rates, and both the first color-changing film layer 121 and the second color-changing film layer 122 are electrochromic film layers.
[0052] The photosensor 300 , the first color-changing film layer 121 , and the second color-changing film layer 122 are all connected to the controller 200 .
[0053] The photosensitive sensor 300 is used to detect the light intensity received by the photochromic glass 100, that is, to obtain the ambient light intensity information.
[0054] In one embodiment, the vehicle's window glasses are all photochromic glass 100, and the photosensitive sensor 300 detects the light intensity received by each window glass in real time, and sends the corresponding ambient light intensity information to the controller 200. The controller 200 determines whether the light intensity received by each window glass exceeds a preset light intensity threshold based on the received ambient light intensity information. If it exceeds, the controller 200 controls the photochromic glass 100 to change color according to a preset light transmittance corresponding to the light intensity received.
[0055] Alternatively, see Figure 3 As shown, the color change control system 10 further includes a wheel speed sensor 400 , and the wheel speed sensor 400 is connected to the controller 200 .
[0056] Among them, the wheel speed sensor 400 is used to monitor the wheel speed information and transmit the information to the microprocessor 230. The microprocessor 230 receives the wheel speed information, determines whether the vehicle is in a driving state or a parking state, and sends the judgment result to the main controller 210. The main controller 210 controls the color change of the color-changing film layer 120 through different color-changing controllers according to the current state of the vehicle.
[0057] In combination with the device in the aforementioned embodiment, based on the wheel speed sensor 400, different controls can be performed on the vehicle's color-changing glass 100 in different states to meet the current shading scenario.
[0058] Figure 4 is a schematic diagram showing the connection between a color-changing controller and a color-changing film layer according to an exemplary embodiment. Figure 4 As shown, the controller 200 includes a plurality of color changing controllers 220 .
[0059] The parking color change controller 222 among the plurality of color change controllers 220 is connected to the second color change film layer 122 in the color change glass 100 .
[0060] The driving color changing controller 221 among the plurality of color changing controllers 220 is connected to the first color changing film layer 121 in the color changing glass 100 .
[0061] In one embodiment, the parking color change control 222 is used to control the color change of the second color change film layer 122 in the color change glass 100 when the vehicle is in a parking state, that is, to control the color change glass 100 to change color slowly, and the driving color change control 221 is used to control the color change of the first color change film layer 121 in the color change glass 100 when the vehicle is in a driving state, that is, to control the color change glass 100 to change color quickly.
[0062] For example, the driving color change controller 221 automatically controls the color change of the color change glass 100 when the vehicle is in driving state, that is, the user does not need to manually input operation instructions, while the parking color change controller 222 is a manual color change controller that requires the user to manually input operation instructions through the vehicle's control panel.
[0063] When driving, the driving color-changing controller 221 controls the color-changing glass 100 to change color quickly, thereby improving the driving comfort and safety of the driver. When parking, the parking color-changing controller 222 controls the color-changing glass 100 to change color slowly, thereby effectively reducing the use cost of the color-changing glass and improving the economy.
[0064] Figure 5 is a flow chart of a method for controlling a color-changing glass according to an exemplary embodiment. Figure 5 As shown, the color changing of the color changing glass 100 can be controlled by the following steps.
[0065] In the first step, the wheel speed sensor 400 collects the wheel speed information of the vehicle in real time and sends the wheel speed information to the microprocessor 230 .
[0066] In the second step, the microprocessor 230 determines whether the vehicle is in a driving state or a parking state according to the received wheel speed information.
[0067] For example, when the wheel speed information indicates 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; when the wheel speed information indicates that the wheel speed of the vehicle is equal to 0 RPM, the microprocessor 230 determines that the vehicle is in a parking state.
[0068] If the vehicle is in driving state, execute the third step, if the vehicle is in parking state, execute the sixth step.
[0069] In the third step, the main controller 210 receives the ambient light intensity information obtained by the light sensor 300 and determines the current lighting environment state of the vehicle.
[0070] For example, if the ambient light intensity information indicates that the light intensity received by the vehicle is greater than a preset daylight intensity threshold, and is greater than the preset daylight intensity threshold for a first preset time period, then the vehicle's lighting environment state is judged to be a daytime driving state, that is, the type of light received by the photochromic glass is natural light, and the fourth step is executed.
[0071] If the ambient light intensity information indicates that the light intensity received by the vehicle is less than or equal to the preset daylight intensity threshold, and is less than or equal to the preset daylight intensity threshold for a second preset time period, then the lighting environment state of the vehicle is judged to be a night driving state, that is, the type of light received by the photochromic glass is non-natural light, and the fifth step is executed.
[0072] The natural light may be sunlight, and the unnatural light may be light emitted by high beams of other vehicles.
[0073] The fourth step is to monitor the light intensity of the vehicle's photochromic glass 100 in real time when the vehicle is in daytime driving state. If the light intensity is greater than the first light intensity threshold, the first photochromic film layer 121 is controlled to change color through the driving photochromic controller 221 according to the target light transmittance corresponding to the current light intensity within the preset first photochromic range. If the light intensity is less than or equal to the first light intensity threshold, the photochromic glass 100 is not controlled to change color.
[0074] After completing step 4, return to step 1.
[0075] The fifth step is to monitor the light intensity of the vehicle's photochromic glass 100 in real time when the vehicle is driving at night. If the light intensity is greater than the second light intensity threshold, the first photochromic film layer 121 is controlled to change color through the driving photochromic controller 221 according to the target light transmittance corresponding to the current light intensity within the preset second photochromic range. If the light intensity is less than or equal to the second light intensity threshold, the photochromic glass 100 is not controlled to change color.
[0076] After completing step 5, return to step 1.
[0077] It is worth noting 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.
[0078] In one embodiment, in order to ensure the material cost and long-term stability of the color change control system 10, when the vehicle is in driving state, usually only the front windshield of the vehicle is color-changed.
[0079] 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 vehicle's color changing glass 100 through the parking color changing controller 230 according to the operation instruction, and returns to the first step after completing the sixth step.
[0080] Among them, when the vehicle is in the parking state, the user can control any color-changing glass of the vehicle to change color to any degree through the user control panel to protect the interior of the vehicle and prevent the interior of the vehicle from being damaged by sunlight.
[0081] Optionally, the controller 200 includes a plurality of color-changing controllers.
[0082] See also Figure 5 As shown, the first color-changing controller 2201 and the second color-changing controller 2202 among the multiple color-changing controllers 220 are both connected to the first color-changing film layer 121, and the electrical signal output by the first color-changing controller 2201 to the first color-changing film layer 121 is different from the electrical signal output by the second color-changing controller 2202 to the first color-changing film layer 121, so that the first color-changing controller 2201 and the second color-changing controller 2202 can control the first color-changing film layer 121 to have different light transmittances.
[0083] In one embodiment, the driving color change controller 220 integrates a first color change controller 221 and a second color change controller 222, wherein the first color change controller 221 is a daylight color change controller, and the second color change controller 222 is a high beam color change controller, and the first color change controller 221 and the second color change controller 222 are both electrically connected to the first color change film layer 121 of the color change glass 100, and the first color change controller 221 and the second color change controller 222 output different electrical signals to the first color change film layer 121, so that the first color change film layer 121 undergoes different degrees of redox reactions, thereby having different light transmittances, wherein the first color change controller 221 outputs The voltage corresponding to the electrical signal is less than the voltage corresponding to the electrical signal output by the second color-changing controller 222. That is to say, when the first color-changing controller 221 controls the first color-changing film layer 121 to change color, the transmittance of the first color-changing film layer 121 is lower, so that the transmittance of the color-changing glass 100 can be adjusted quickly and in a large range when driving during the day to prevent sunlight from directly 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 transmittance of the first color-changing film layer 121 is higher, so that the transmittance of the color-changing glass 100 can be adjusted quickly and in a small range when driving at night, thereby preventing the high beam from directly shining into the driver's eyes without affecting the field of vision.
[0084] In another embodiment, the parking color change controller 230 may also integrate a third color change controller and a fourth color change controller, wherein the third color change controller is a daylight color change controller, and the fourth color change controller is a high beam color change controller, and the third color change controller and the fourth color change controller are both electrically connected to the second color change film layer 122 of the color change glass 100, so that when the vehicle is in the parking state, the transmittance of the color change glass 100 can also be automatically and slowly adjusted.
[0085] Alternatively, see Figure 3 As shown, the controller 200 further includes a main controller 210 and a color change controller 220 . The main controller 210 is connected to the photosensor 300 , and each of the color change controllers 220 is connected to the main controller 210 .
