Problems solved by technology

[0004] Although the above method can adjust the light intensity of the window glass, the setting of polarizing film and liquid crystal film or silver halide can only distinguish the light intensity, so it is necessary to turn on the low beam or high beam when driving at night. Under the influence of the car lights, the window glass will also react and produce a shading effect, making the settings of the polarizing film and liquid crystal film or silver halide uncontrollable during use, which affects the safety of the driver driving at night, causing driving inconvenience
[0005] The conventional way to improve the problems in the above-mentioned prior art is to use electronically controlled color-changing glass as the window glass, and adjust the lightness of the electronically controlled color-changing glass to realize the adjustment of the shading effect of the vehicle window glass. The energy saving effect of window glass is poor
[0006] Since the existing shading objects that can be added are all solid or liquid, accommodating chambers are set in the window glass, and the shading objects are filled into the window glass in real time according to the natural light intensity, which will make the distribution of the shading objects uneven and the shading At this time, there are basically no shading objects above the accommodating cavity, which makes the shading of the window glass uneven and affects the shading effect of the window glass. For the purpose of improving the shading effect of the window glass, it is not easy for those skilled in the art to fill the shading material into the vehicle window glass in real time according to the natural light intensity; and the shading material is generally piled up at the bottom of the accommodating cavity , will block the driver's driving line of sight and affect the driver's driving safety

Embodiment 1

[0032] Such as figure 1 As shown, the vehicle window glass light intensity adjustment structure includes the vehicle window glass 1 .

[0033] Specifically, if figure 1 As shown, the light intensity adjustment structure includes a shading powder 2, a control device 3, a light sensor 4 capable of detecting the intensity of natural light, an accommodation chamber 11 arranged in the window glass 1, and an air intake pipe in communication with the accommodation chamber 11. 12 and an air outlet pipe 13, the control device 3 includes an air pump 5 capable of blowing the shading dust 2 to move, and when the natural light increases, the control device 3 receives the signal from the light sensor 4 and passes the shading powder 2 from the air intake pipe 12 through the air pump 5 In the accommodating cavity 11, when the natural light weakens, the control device 3 moves the shading powder 2 from the accommodating cavity 11 to the air outlet pipe 13 through the air pump 5 after receiving...

Embodiment 2

[0042] The content of this embodiment is basically the same as that of Embodiment 1, the difference being that:

[0043] Control device 3 comprises solenoid valve one, control switch one, solenoid valve two and control switch two, and solenoid valve one is arranged in the intake pipe 12 and control switch one can control solenoid valve one on-off intake pipe 12, and intake pipe 12 is connected with available The storage room 1 where the shading powder 2 is placed, the air pump 5 is set in the storage room 1, the solenoid valve 2 is set in the air outlet pipe 13 and the control switch 2 can control the solenoid valve 2 to disconnect the air outlet pipe 13, and the air outlet pipe 13 is connected with a light-shielding Storage room two for powder placement.

[0044] Solenoid valve 1 and solenoid valve 2 are used to make the whole control more convenient and can be directly controlled electrically. The air pump 5 can drive the shading powder 2 to be located in the accommodation c...

Abstract

The invention provides a vehicle window glass light intensity adjustment structure, which belongs to the technical field of automobiles. It solves the problem that the shading effect of the existing window glass cannot be adjusted in real time. The light intensity adjustment structure of the vehicle window glass includes an accommodation cavity arranged in the vehicle window glass. The light intensity adjustment structure includes shading powder and a control device. The control device includes an air pump capable of blowing the shading dust to move. The device passes the shading powder into the accommodation chamber through the air pump, and the control device discharges the shading powder from the accommodation chamber through the air pump when the natural light is weakened. The vehicle window glass light intensity adjusting structure can adjust and improve the shading effect of the vehicle window glass in real time.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to a structure for adjusting the light intensity of a window glass. Background technique [0002] With the continuous improvement of people's living standards, automobiles, as a common means of travel, have gradually increased their comfort requirements. With the large number of glass products such as car sunroofs involved in the design, the light intensity in the driving environment inside the car is getting stronger and stronger, especially in sunny days or in special areas where the light intensity is extremely high, which seriously affects the safety of driving. [0003] In the prior art, the light intensity of the car window is usually adjusted by pasting polarizing film and liquid crystal film on the glass, or by adding color-changing substances such as silver halide during glass manufacturing to realize the adjustment of the light intensity of the car window. [0004] Altho...
