[0056] Specifically, the surface of the first protective layer 1 is coated with a self-cleaning water-conducting layer by vapor deposition, sputtering or immersion technology to achieve waterproof, dustproof, scratch-resistant and self-cleaning functions. The surface of the photovoltaic power generation layer 2 is coated with a perovskite or gallium arsenide layer by vapor deposition, sputtering or immersion technology.

[0058] Specifically, the space extension layer 7 uses film stretching and multi-layer special coating to add a transmission-enhancing and reflection-reducing layer. The transmission-enhancing and reflection-reducing layer is a material with a certain film thickness, number of film layers and thickness combined with an optical adhesion layer to increase light band absorption.

[0059] Specifically, the surface of the second protective layer 8 is coated with a self-cleaning water-conducting layer by vapor deposition, sputtering or immersion technology to achieve waterproof, dustproof, scratch-resistant and self-cleaning functions. A temperature sensor 10 and a photosensitive sensor 11 are installed on the temperature control board.

[0060] The temperature sensor 10 is used to power the thermal barrier and temperature control module when it detects that the temperature is below the threshold. After power is turned on, the thermal barrier and temperature control module generates heat to increase the temperature of the dimming layer 41. The dimming layer 41 is maintained at a temperature where the material response speed meets the usage requirements.

[0061] A smart control system for a multifunctional vehicle-mounted dimming glass, the smart control system comprising a control board 9, a temperature sensor 10, a photosensor 11, a starry sky top layer 6, a dimming layer 41, a heating layer 31, a photovoltaic power generation layer 2, a boost inverter module 13, a dimming glass module 14, and a sensing optical path module.

[0062] The input terminal of the control board 9 is electrically connected to the output terminals of the temperature sensor 10 and the photosensitive sensor 11, respectively. The output terminal of the temperature control board is electrically connected to the input terminals of the starry sky top layer 6, the dimming layer 41 and the heating layer 31, respectively.

The output terminal of the boost inverter module 13 is electrically connected to the input terminal of the dimming glass module 14. The output terminal of the dimming glass module 14 is electrically connected to the input terminal of the dimming layer 41. The input terminal of the dimming glass module 14 is electrically connected to the output terminal of the photovoltaic power generation layer 2.

[0064] Specifically, the photosensitive circuit module 12, control board 9, boost inverter module 13, dimming glass module 14, photovoltaic power generation layer 2 and dimming layer 41 constitute the anti-glare control system of the vehicle dimming glass.

[0065] The boost inverter module 13 uses a DC-DC converter to increase the voltage required by the dimming module 4, and then converts it into AC power through a DC / AC conversion circuit.

[0066] Specifically, in the anti-glare control system, the key to determining the degree of influence of light intensity on human eye glare lies in the accurate calculation of the glare index. As an important indicator, the glare index can directly reflect the magnitude of light intensity and the intensity of glare perception caused by it.

[0067] Glare Index (GR)

[0068] External calculation formula:

[0069] In-vehicle calculation formula:

[0070] C vi The brightness (cd / m²) of the light curtain produced when light emitted from a lamp is directly directed at the eye. 2 ), C ve The luminance (cd / m²) of the light curtain produced by light directly incident on the eye due to environmental factors. 2 The GR value ranges from 0 to 100. The higher the value, the stronger the glare effect and the less the eyes can adapt.

[0071] Specifically, the dimming layer 41 is a sandwich structure formed by bonding a liquid crystal film between two layers of glass under high temperature and high pressure. The dimming layer 41 achieves dynamic switching between transparent and dimly lit states through voltage and current control, temperature control, light control, and pressure sensing control, so as to control the light transmittance of the vehicle dimming glass.

[0072] Specifically, the control board 9 judges the illuminance signal input by the photosensitive circuit module 12. When the illuminance value is detected to be greater than the set threshold, the control board 9 immediately issues a command to control the voltage value of the dimming layer 41 to change the light transmittance of the vehicle dimming glass.

[0073] Working principle and usage:

[0074] The first protective layer 1 has a self-cleaning water-conducting layer coated on its surface by vapor deposition, sputtering or immersion technology to achieve waterproof, dustproof, scratch-resistant and self-cleaning functions.

[0075] The photovoltaic power generation layer 2 has a perovskite or gallium arsenide layer coated on its surface by evaporation, sputtering or immersion technology. Perovskite and gallium arsenide are high-performance photovoltaic power generation materials used to supply power to the intelligent control system.

[0076] The thermal barrier and temperature control module 3 includes a heating layer 31, on which a first conductive point 32 and a second conductive point 33 are provided. The heating layer 31 is composed of a substrate and a heating coating. The heating coating is applied to the surface of the substrate by magnetron sputtering, screen printing or vapor deposition.

[0077] The dimming module 4 includes a dimming layer 41 with a third conductive point 42 and a fourth conductive point 43. The heating layer 31 is electrically connected to the control board 9 through the first conductive point 32 and the second conductive point 33. When the temperature sensor 10 detects that the temperature is lower than the threshold, it will supply power to the thermal barrier and temperature control layer. After power is supplied, the thermal barrier and temperature control layer emits heat to increase the temperature of the dimming layer 41. The dimming layer 41 is maintained at a low temperature where the material response speed meets the usage requirements. This solves the problem of slow low-temperature response speed, poor dimming effect, and poor actual user experience caused by the low temperature and slow material response speed of the dimming layer 41. This allows the product to be used in all weather conditions and in all directions, and it is resistant to low temperatures and can be used inside and outside the vehicle.

[0078] The transparent display layer 5 is used to achieve full-color high-definition display. It achieves high-definition display through high-frequency refresh and works in conjunction with the dimming layer 41 to achieve immersive, flat-lying high-definition viewing. At the same time, it is transparent when not displaying anything, so it does not affect the function of the dimming layer 41.

[0079] The starry sky top layer 6 is a transparent partial display layer, which is made of LED, OLED or micro LEDD. The display incorporates the starry sky and, in combination with the dimming layer 41, enables an immersive, flat, high-definition viewing of the starry sky and universe, which is usable both day and night.

[0080] The space expansion layer 7 is constructed by using film stretching and multi-layer special coating to increase the transmission and reduce the reflectivity of the layer. The transmission and reduce the reflectivity layer is a material with a certain film thickness, number of film layers and thickness combined with an optical bonding layer to increase the absorption of light bands. This makes the reflected image color real, bright and without ghosting, and realizes a huge spatial expansion of the visual and optical effects of the vehicle space reflection reflection, giving users a very good riding experience.

[0081] The second protective layer 8 has a self-cleaning water-conducting layer coated on its surface by vapor deposition, sputtering or immersion technology to achieve waterproof, dustproof, scratch-resistant and self-cleaning functions.

[0082] Control board 9, temperature sensor 10 and photosensitive sensor 11, the temperature control board is equipped with temperature sensor 10 and photosensitive sensor 11;

[0083] When a car is in motion, strong sunlight can penetrate the vehicle's dimming glass and enter the driver's field of vision, causing glare. Similarly, if the light source suddenly turns off, the driver's eyes may not be able to adapt to the change in light quickly enough. Both situations result in blurred vision and significantly increase the probability of traffic accidents. Based on optical detection technology using a photoelectric sensing module, the system accurately collects the light intensity emitted by the light source in real time and compares it meticulously with a pre-set glare threshold. Through this rigorous comparative analysis, it precisely determines whether the current light meets the standard for glare. Once glare is detected, the control board 9 immediately activates an intelligent control mechanism. Based on the light intensity and a preset algorithm, it precisely and dynamically controls the light transmittance of the vehicle's dimming glass, thereby ensuring the driver has a clear and undisturbed field of vision.

[0084] Specifically, the input terminals of the control board are electrically connected to the output terminals of the temperature sensor, the photosensitive sensor, and the single alternating light field sensor, respectively. The output terminal of the control board is electrically connected to the input terminal of the system control module. The output terminal of the system control module is electrically connected to the input terminal of the electrochromic EC film. The output terminal of the electrochromic EC film is electrically connected to the input terminal of the operating status feedback module to control the light transmittance of the electrochromic EC film. The input terminal of the operating status feedback module is electrically connected to the output terminal of the control board. The output terminals of the control board are electrically connected to the input terminals of the working indicator light, the instrument control module, and the display terminal, respectively.

[0085] Temperature sensors are used to collect temperature signals outside the vehicle, photosensors are used to collect incident light intensity signals outside the vehicle, single alternating light field sensors are used to perform high-precision optical displacement measurements, solving the problems of poor consistency, large size and difficulty in integration of multiple alternating light field light sources inside the vehicle, and controllers are used to control the operation of electrochromic EC films.

[0086] Temperature and light sensors are responsible for detecting the outside temperature and light intensity, respectively. They accurately transmit the collected signals to the control board. The vehicle power supply provides power to the electrochromic EC film. Simultaneously, the control indicator lights up to visually display the system's operating status. The system control module receives signals from the control board via a LIN bus, enabling data sharing and efficient transmission. Furthermore, the system control module interacts with the instrument cluster control module via a CAN network, ensuring accurate information flow between different modules. The control board's data settings include sensor threshold settings. It compares and analyzes the real-time data returned by the sensors with pre-set thresholds, making corresponding calculations and responses. When the data detected by the temperature and light sensors reaches a certain set threshold, the controller integrates stored historical data with current real-time data for in-depth analysis, quickly and effectively feeding the analysis results back to the display terminal. Under normal operating conditions, the control board continuously detects and processes various data to ensure stable system operation. It takes appropriate actions when the following two situations occur:

[0087] a. A single sensor fails when its data falls below a threshold, displaying the sensor's status.

[0088] b. When the data from a single sensor exceeds a threshold, a control signal is issued.
