Referring to fig. 1 in conjunction with fig. 2, in one embodiment, an example of a specific structure of a vehicle having electrochromic glazing may be a structure including: the car body 1, the electrochromic glass 2 and the electric switch 3. At least one of a front windshield installation position 101, a rear windshield installation position 102, a side window installation position 103, and a roof installation position 104 of the vehicle body 1 is installed with the electrochromic glass 2. The electric switch 3 is electrically connected with the electrochromic glass 2, the electric switch 3 comprises a manual switch 301 and an automatic switch 302, the manual switch 301 and the electrochromic glass 2 form a first color-changing circuit 4, and the automatic switch 302 and the electrochromic glass 2 form a second color-changing circuit 5. The first color-changing circuit 4 and the second color-changing circuit 5 are in a parallel relation, and the electrochromic glass 2 can work when the manual switch 301 and/or the automatic switch 302 are closed, for example, when the illumination condition for closing the automatic switch 302 is not met, a user can adjust the electrochromic glass by manually closing the manual switch 301 to achieve the purposes of sun protection, peep prevention and the like, or for example, the user manually closes the manual switch 301, but the illumination condition for closing the automatic switch 302 appears, and the automatic switch 302 can still be closed to adjust the electrochromic glass 2, so that the driving safety is ensured. The first color-changing circuit 4 is integrated with the second color-changing circuit 5 in the vehicle circuit. The vehicle with the electrochromic glass can achieve the purposes of sun screening, warm keeping, peep prevention and the like of a user by adjusting the electrochromic glass, and meanwhile, can immediately protect human eyes to prevent the too strong illumination and ensure the driving safety.

Referring to fig. 3, in one embodiment, an example of a specific structure of a vehicle having electrochromic glass may be that electrochromic glass 2 is mounted at a front windshield mounting position 101 of a vehicle body 1. The second color-changing circuit 5 further includes a light intensity sensor 501 and a control unit 502, the control unit 502 is electrically connected to the light intensity sensor 501 and the automatic switch 302, respectively, and outputs an on or off electrical signal to the automatic switch 302 according to a sensing input of the light intensity sensor 501. The luminance below 3500 lumen is the luminance that the human eye can work normally, when the luminance of the direct light or the reflected light reaches 4000 lumen, the human eye starts to take the light, when the human eye tries to see the areas, only the white flash light, namely the glare, can be seen, in order to reduce the discomfort caused by the large amount of light entering the eyes, the human eyes can be dazzled, and the vision is influenced at this moment. Once the brightness of the light reaches 10000 lumens, the eyes begin to completely filter out the light because the received light is too strong, and the eyes are damaged by the strong light after being exposed for too long time, which causes temporary or even permanent blindness, and the brightness of the high beam can reach about 20000 lumens. The illuminance sensor 501 is a sensor that converts the illuminance into an electrical signal, for example, when the vehicle is driving at night, a high beam is applied to the oncoming vehicle, when the vehicle senses the illuminance of lumens that affect the vision, the illuminance sensor 501 inputs a signal that the illuminance is too strong to the control unit 502, and the control unit 502 outputs an electrical signal that turns on or off the switch to the automatic switch 302, so that the electrochromic glass 2 changes color to intercept strong light, thereby protecting the eyes of people and ensuring the driving safety. The illuminance sensor is arranged, so that the vehicle can intercept high lumen illumination, human eyes are protected, sight line is prevented from being influenced, and driving safety is improved.

As shown in fig. 3, in one embodiment, the second color-changing circuit may further include a photosensitive sensor 503, and the photosensitive sensor 503 is electrically connected to the control unit 502. The photosensitive sensor is a sensor which converts optical signals into electric signals by using a photosensitive element, has a sensitive wavelength near the visible wavelength, including infrared wavelength and ultraviolet wavelength, and is a sensitive device with a response or conversion function on external optical signals or light radiation. The light sensor 503 is very sensitive to light signals, so that a specific light intensity threshold can be set to more accurately control the electrochromic glazing 2. For example, because the factors influencing safe driving at night and in the daytime are different, the signal output sensed by the photosensitive sensor 503 can be output to the control unit 502 to judge whether the vehicle is at night or in the daytime, the control unit 502 can set different judgment thresholds accordingly, and then the illumination threshold influencing safe driving and the illumination signal output by the illumination sensor 501 to the control unit 502 can be generated according to different night and daytime, so that the coloring and fading degrees of the electrochromic glass 2 are accurately adjusted, and the safety is ensured while the comfort and the privacy are met. Such as: when the vehicle is driving at night, the main factor influencing safety is the interference of the high beam when the vehicle meets the opposite side, the illumination can reach 20000 lux, the judgment threshold is set to 20000 lux, and when the illumination reaches 20000 lux, the control unit 502 adjusts the coloring degree of the electrochromic glass 2 to a deeper level so as to block the light of the high beam; or as the road surface environment is too dark, statistics shows that the road surface illumination for safe driving is at 20 lux, traffic accidents frequently occur when the road surface illumination is lower than 20 lux, the judgment threshold value is set to be 20 lux, and when the road surface illumination is lower than 20 lux, the control unit 502 enables the color fading degree of the electrochromic glass 2 to be strengthened to a corresponding level to increase the light transmittance, so that the driving safety is ensured. When the vehicle runs in the daytime, the main factors influencing safety include over-strong sunlight, the illuminance of the sunlight directly irradiating the ground in sunny days can reach 100000 lux, the influence on the vision of a driver can be caused no matter the sunlight directly irradiates into human eyes or the light reflected by the rear windshield of a front vehicle, the driving safety is endangered, a corresponding judgment threshold value is set, and when the threshold value is reached, the control unit 502 strengthens the coloring degree of the electrochromic glass 2 to a corresponding grade, so that the human eyes are protected; or when the light enters the tunnel, the light is too dark, the illumination value is lower than the set threshold value, the control unit 502 enables the fading degree of the electrochromic glass 2 to be enhanced to the corresponding grade, the light transmittance is increased, and the clear driving sight is ensured.

In the above-described embodiment, the control unit 502 of the second color-changing circuit 5 may be an onboard processor, but is not limited thereto. In an embodiment, an example of a specific structure of the second color-changing circuit 5 may be that the control unit 502 and the automatic switch 302 are distributed, that is, the control unit 502 is a cloud processor, rather than an on-board processor as the control unit 502, and the control unit 302 may be selected according to requirements of control accuracy and reliability, where the on-board processor generally has higher reliability but has lower computing capability than the cloud processor.

Referring to fig. 1, in one embodiment, a specific structure example of a vehicle having electrochromic glass may be such that electrochromic glass 2 is mounted at each of a front windshield mounting position 101, a rear windshield mounting position 102, a side window mounting position 103, and a sunroof mounting position 104 of a vehicle body 1. Electrochromic glass is all installed to the whole door window mounted position of vehicle of this embodiment, when guaranteeing driving safety, still can satisfy the user to sun-proof, peep-proof and build the demand of light efficiency scene in the car, promotes use comfort, abundantly uses and experiences.

Referring to fig. 4A and 4B in conjunction with fig. 2, in one embodiment, the electrochromic glass 2 may include a light-adjusting film glass 201. The light adjusting film 6(PDLC, Polymer Dispersed Liquid Crystal), which is a Polymer Dispersed Liquid Crystal, is a film capable of adjusting the light passing state, specifically, the light adjusting film is controlled by voltage to work between a milky white state and a transparent state, thereby achieving the dual functions of privacy protection and transparent lighting. The light modulation film glass is formed by, as shown in fig. 4, generally injecting a mixed material prepared from liquid crystal 601 and polymer 602 into the middle of two transparent conductive films 603 to form a sandwich structure, and then manufacturing a light modulation film 6, an EVA (ethylene vinyl acetate) film 604 and two pieces of glass 605 into a sandwich glass product, namely the light modulation film glass 201, by a sandwich process, wherein the working principle is that when the light modulation film 6 is in a power-off state, as shown in fig. 4A, the middle liquid crystal 601 material is in a disordered arrangement state and blocks light from penetrating through the films, and the observed effect is in a milky opaque state; when the light adjusting film 6 is in a power-on state, under the action of an electric field, the middle liquid crystal 601 material is in ordered arrangement, so that light can penetrate through the film, and the effect is seen to be a transparent colorless film state. When the light-adjusting film glass is used specifically, for example, when the external illumination intensity is strong, the automatic switch 302 is automatically turned off, or a user manually turns off the manual switch 301 to enable the light-adjusting film glass 201 to be powered off and return to a milky white state, so that light is shielded, and the effects of sun protection and privacy protection are achieved.

In one embodiment, an example of a specific structure of the electrochromic glazing 2 may be, including suspended particle glass. The suspended particle glass is a sandwich structure formed by dispersing particles with oriented light absorption characteristics in suspension and combining the particles with a transparent film, namely an SPD (Surge-dispersed) film, and the change of the visible light transmittance and the shading coefficient of the glass is controlled by 110V voltage. When not electrified, the particles with Brownian motion are randomly arranged, and can absorb more than 99% of visible light and black state. When an alternating voltage of 110V is applied, the particles are aligned under the action of the electric field, and light rays pass through. The suspended particle glass can be changed from opaque (black state) to transparent within 1 second and from transparent to opaque (black state) within 1-5 seconds within the range of visible light, at the moment, more than 99% of visible light can be blocked, 99.9% of ultraviolet light can be absorbed, and the transmittance can be continuously adjusted. When the glass is used specifically, for example, when the external illumination intensity is strong, the automatic switch 302 is turned off automatically, or a user turns off the manual switch 301 manually to turn off the suspended particle glass to a black state, so as to shield light and play a role in preventing sun.

In one embodiment, the electrochromic glazing 2 may be of a specific construction, including a dye liquid crystal privacy glass. The dye liquid crystal dimming glass is formed by adding dichroic dye molecules into a liquid crystal material, wherein the dichroic dye molecules can be kept in parallel arrangement with the liquid crystal molecules in orientation and rotate in the same phase with the liquid crystal molecules under the action of an electric field. Under the action of an electric field, when the long axis of the liquid crystal is vertical to the surface of the glass, light rays are basically absorbed by the dichroic dye liquid crystal, and the glass is in a dark color state; when the short axis of the liquid crystal is perpendicular to the glass surface, the dichroic dye is perpendicular to the glass surface along with the liquid crystal, the absorption of light by the dye is reduced, and the glass is in a transparent state. When the liquid crystal display device is used specifically, for example, when the external illumination intensity is strong, the automatic switch 302 is automatically turned on, or a user turns on the manual switch 301 manually to enable the dye liquid crystal dimming glass to be electrified and adjusted to be in a dark color state, so that light is shielded, and a sun-proof effect is achieved.

In one embodiment, the electrochromic glazing 2 may be, in particular configurations, comprised of all-solid-state electrochromic glazing. The all-solid-state electrochromic glass is prepared by sputtering metal and nonmetal materials such as metal tungsten and lithium on the surface of glass by a vacuum magnetron sputtering coating technology, applying 3V direct current to the all-solid-state material to generate reversible electrochemical reaction, and under the drive of an electric field, lithium ions are transferred to a cavity of the tungsten, so that the transferred ions are few, and the color of the glass is light; the color of the glass becomes dark due to more migrated ions; when a reverse voltage is applied or the power is cut off, the lithium ions return to the original position, and the color of the glass changes from dark to light or is completely transparent. When the solid-state electrochromic glass is used specifically, for example, when the external illumination intensity is strong, the automatic switch 302 is automatically closed, or a user manually closes the manual switch 301 to electrify the solid-state electrochromic glass to change the solid-state electrochromic glass into a dark state, so that light is shielded, and a sun-proof effect is achieved.

The electrochromic glasses can work in a normal-temperature environment, wherein the adjustability of only the light modulation film glass is in two states and has a general light transmittance range, and the adjustability of the other three electrochromic glasses is infinitely adjustable and has a good light transmittance range; the all-solid-state electrochromic glass has the best heat insulation property and is the best choice for playing a role in sun protection; the working voltages required by the all-solid-state electrochromic glass and the dye liquid crystal dimming glass are only 3V and 5V respectively, and the all-solid-state electrochromic glass and the dye liquid crystal dimming glass are better choices in the aspects of energy conservation and safety. In practical application, the type of the electrochromic glass can be customized and selected for a vehicle according to the requirements of a user.

In one embodiment, the manual switch 301 may be embodied as a physical key located on a center console of the vehicle 1 or a virtual key located on a center screen, where the key is understood in a broad sense, that is, the key includes a button, a key, and the like, and an operator can perform an operation of triggering the manual switch 301 to turn on or off by pressing or touching the key, so that the driver can operate the switch during driving.
