In some embodiments, referring to fig. 1, light-shielding windows are formed at two ends of the mounting frame 1, and the light-shielding shutter 2 is disposed in the inner cavity of the mounting frame 1 in parallel with the light-shielding windows and is fixedly connected to the inner wall of the mounting frame 1.

In some embodiments, referring to fig. 3, 4 and 5, the light-shielding shutter 2 includes a motor 21, a light-shielding belt 22 and two rotating shafts 23, the two rotating shafts 23 are disposed opposite to each other and are respectively in transmission connection with the light-shielding belt 22, the motor 21 is in transmission connection with the rotating shafts 23 through output shafts thereon, ends of the motor 21 and the rotating shafts 23 are further respectively fixedly connected with an inner wall of the mounting frame 1 through bearing connectors 24, and the motor 21 is further electrically connected with the light detection assembly.

Preferably, in order to ensure that the frequency of the light-shielding belt 22 is controllable, and simultaneously, in order to ensure that the flash frequency of the illumination lamp on the vehicle is consistent with the light-shielding frequency of the light-shielding belt 22 (mainly, when the light-shielding function is realized, the field of vision of a driver is clear), in the present embodiment, the positioning signal counting of the sensor for performing the positioning signal acquisition on a certain point on the light-shielding belt 22 in the rotation process can be realized through the wall mounting in the mounting rack, so that the frequency acquisition function is realized, specifically, the positioning signal can be generated when the certain point on the light-shielding belt 22 passes through the photoelectric sensor, and the positioning signal is input into the microprocessor of the light detection assembly, thereby realizing the acquisition of the frequency of the light-shielding belt, and further realizing the frequency synchronization.

Specifically, the electronic liquid crystal shutter becomes black and opaque when a certain voltage is applied, and transmits light without applying the voltage, so that the electronic liquid crystal shutter can be realized by directly using the synchronization signal for synchronization.

In this embodiment, a light shielding system for preventing high beam from irradiating during night driving is substantially disclosed, the system includes a light detection assembly, a light shielding shutter and a vehicle lighting lamp, the vehicle lighting lamp is set to a flash mode with a flash frequency greater than or equal to 50Hz, the light detection assembly is electrically connected to the light shielding shutter and the vehicle lighting lamp, the light detection assembly is configured to detect the flash frequency of the opposite vehicle lighting lamp in real time, and adjust the light shielding frequency of the light shielding shutter of the vehicle according to the detected flash frequency of the opposite vehicle lighting lamp to be in inverse synchronization with the flash frequency, and the light detection assembly is further configured to adjust the flash frequency of the vehicle lighting lamp according to the light shielding frequency of the light shielding shutter of the vehicle to be in synchronization.

The light detection assembly uses the device disclosed in fig. 2, the light shielding shutter can be realized by the light shielding plate, and other shutter structures capable of realizing the above functions can be adopted, so long as the light shielding plate can quickly transmit light and quickly shield light under the control of a synchronous signal, the light shielding plate can also be made into a form of glasses, the glasses can be directly worn by a driver, and the structure of the glasses is similar to that of the existing shutter type 3D glasses. If the automobile lamp is made into a glasses form, the light detection assembly and the automobile lamp can achieve the function of adjusting the flicker frequency in a wireless communication mode. The automobile lamp needs to be an illuminating lamp which can be quickly turned on and off and does not need to have residual light when the automobile lamp is quickly turned off, the LED lamp can be turned on and off by using the square wave signal generator and the power amplifier, and common lamp light can be changed into flickering light which is turned on and off once.

The opposite synchronization of the shutter and the lamplight between two vehicles can be realized only if the vehicles running oppositely can receive and identify the flicker frequency and the phase of the lamplight of the opposite vehicle. This can be done with an optical receiver (optical signal receiving amplifier) or in other ways as long as it can receive the frequency and phase of the flash that identifies the opposite vehicle light.

In a second aspect, referring to fig. 7, 8 and 9, the embodiment of the invention further discloses a sun visor, which includes a sun visor body 7 and the light shielding plate, wherein an installation opening 8 is formed in one side of the sun visor body 7 away from the roof, the light shielding plate is arranged in the installation opening 8, and the light shielding plate is pivotally connected with two ends of the installation opening 8 through the installation frame 1 thereon.

In a third aspect, referring to fig. 10, an embodiment of the present invention further discloses a light shielding method for preventing high beam irradiation during night driving, where the light shielding plate is used in the method, and the method includes the following steps:

s1: setting the automobile illuminating lamp to be in a flashing state with the flashing frequency being more than or equal to 50Hz in advance;

s2: adjusting the position of the light-shielding plate to be right in front of the sight of a driver;

s3: receiving an optical signal of an opposite automobile illuminating lamp, and analyzing the flicker frequency of the opposite automobile illuminating lamp optical signal;

s4: the light shielding frequency of the light shielding shutter on the light shielding plate and the flashing frequency of the vehicle lighting lamp are reversely synchronous with the flashing frequency of the opposite vehicle lighting lamp.

The method changes the common light of the car lamp into flashing light which is turned on and off, and the flashing frequency can be 50HZ (flashing 50 times per second) or more than 50 HZ. So that the eyes do not perceive the light to flicker. The light-shading shutter is arranged in front of eyes of a driver, and when the shutter is opened, the driver can see vehicles and road conditions in front through the shutter opened in front of the eyes; when the shutter is closed, the driver is momentarily (for a very short time) blocked from sight, and the driver cannot see the front, and the opposite light cannot reach the eyes of the driver. The shutter is synchronous with the light of the vehicle, namely the shutter is opened when the light of the vehicle is bright. When the light of the vehicle is off, the shutter is closed.

When the light (flashing light) of the opposite vehicle is on, the shutter in front of the eyes of the driver of the vehicle and the light of the vehicle are both closed, so that the light of the opposite vehicle (the vehicle provided with the flash lamp and the shutter) can not irradiate the eyes of the driver of the vehicle. Meanwhile, the light of the vehicle is also closed, so that the sight of an opposite driver cannot be influenced.

When the light (flashing light) of the vehicle coming from the opposite side is turned off, the shutter in front of the eyes of the driver of the vehicle and the light of the vehicle are both opened. Thus, the opposite vehicle and the road condition in front can be seen clearly, and the light of the opposite vehicle can not be seen. At the moment, the shutter in front of the eyes of the driver of the opposite vehicle is closed, and the light of the vehicle can not irradiate the eyes of the driver of the opposite vehicle.

The speed of flashing light is high, and synchronous with the opening and closing speed of the shutter, human eyes can not feel that light flashes and can not feel that the shutter in front of the eyes is opened and closed at a high speed. Thus, the driver can see the opposite vehicle and the road condition in front, but can not see the light of the opposite vehicle. The interference of the light of the opposite vehicle to the sight of the driver is avoided.

Specifically, referring to fig. 11, the shutter and light for car a are both in the open state and the shutter and light for car B are both in the closed state. At this time, the vehicle A can see the vehicle B, but the light can not illuminate the eyes of the driver of the vehicle B.

Referring to fig. 12, the shutter and light of car a are both in the closed state and the shutter and light of car B are both in the open state. At this time, the vehicle B can see the vehicle A but cannot see the light of the vehicle A, and the light of the vehicle B cannot illuminate the eyes of a driver of the vehicle A. If the light flashing frequency is 50HZ, the car a and the car B can see each other 50 times in one second. Because the lights are in reverse synchronization, the opposite car can be seen, but the lights of the opposite can not be seen.

When the A car and the B car run relatively, if the A car receives the flashing signal of the light of the B car firstly. The car a amplifies the signal back to the car a light. The light of the A car and the light of the B car are reversely synchronized. Namely, the B car light turns on the A car light and turns off the A car light, and the B car light turns off the A car light and turns on the A car light. And then the vehicle B can also receive the light signal of the vehicle A, and the light frequency and the phase of the vehicle B are kept unchanged because the light signal of the vehicle B is reversely synchronous with the light signal of the vehicle A. Thus, the opposite vehicle can be seen, but the light of the opposite vehicle can not be seen.

By using the method provided by the embodiment, the vehicle of the opposite side and the road condition in front can be seen clearly at night when the vehicle is relatively driven, but the light of the vehicle of the opposite side cannot be seen. The problem that the light of the vehicle interferes with the sight of the driver of the other side is avoided. A completely new method is adopted. The vehicle running at night can completely avoid the irradiation of the light of the opposite vehicle. The driving at night is safer.

In summary, the above-mentioned scheme provided by the embodiment of the present invention has the following advantages:

the practicality is strong, and the car light shines each other at night and disturbs driver's sight, just converts into the dipped headlight by the high beam, also can influence the driver to the observation of distant place thing, influences driving speed again. The scheme can completely solve the interference of the lamplight of the opposite side vehicle to the sight of the driver.

The method is simple and feasible, and the common lamplight related in the scheme is changed into flashing light, the signals between the two vehicles are synchronous, and the shutter for fast blocking light and transmitting light can be completely realized by using the existing technology and materials.
