This shield glass can improve driving safety nature according to light intensity in the external environment condition light conditions automatically regulated driver's cabin.
Description
Technical field
This utility model relates to a kind of shield glass, before especially relating to the automobile of a kind of adaptive environment luminous flux
Windshield.
Background technology
According to statistics, there is a considerable amount of motor traffic accidents that the driving operating mode at driving at night or special weather occurs every year.
Along with the technology upgrading of automobile product, increasing automobile is equipped with xenon headlight, and xenon lamp can make driver obtain
Good sight line, but when meeting at night, part driver adjusts far and near light, the other side driver during meeting the most in time
Under high light, do not see front situation, cause the generation of vehicle accident.Sufficient fair weather condition is irradiated, by force at sunlight
Driver can be caused sight obstruction by light irradiation, particularly the accumulated snow road conditions in the north, and time fine, accumulated snow is to sunlight
It is bad that reflection will also result in pilot's line of vision.
Utility model content
This utility model provides the shield glass of a kind of adaptive environment luminous flux, solves outside vehicle ambient light
The problem that driver causes sight obstruction is caused according to condition when changing.
Technical solutions of the utility model are as follows: the shield glass of a kind of adaptive environment luminous flux, including the glass that keeps out the wind
Glass body, light sensor, controller, voltage source and photoconductive resistance, described controller receives light sensor and controls electricity
Potential source break-make, described windshield body include the first glassy layer, the second glassy layer and be glued at described first glassy layer,
Dimming liquid crystal film between second glassy layer, described light sensor is arranged at the outside of described windshield body, described
Photoconductive resistance is arranged at the inner side of described windshield body, and described dimming liquid crystal film, photoconductive resistance and voltage source series connection are even
Connect.
Preferably, described photoconductive resistance is arranged on vehicle instrument desk surface.
Preferably, described controller is ECU.
Preferably, described voltage source voltage is 12V.
The advantage of technical scheme provided by the utility model is: controls device and is simply easily achieved, utilizes photoconductive resistance
Under different light intensity, the difference of resistance adjusts photoconductive resistance dividing potential drop, adjusts series connection with it tune in the same circuit further
The voltage of light liquid crystal film, reaches to adjust the effect of windshield body light transmittance.Controller has only to receive preposition photosensitive
Sensor judges whether to need voltage fed, it is to avoid complicated judgement and pressure regulation program, reliable.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
As it is shown in figure 1, the shield glass of the adaptive environment luminous flux involved by the present embodiment, including the glass that keeps out the wind
Glass body 1, light sensor 2, controller 3,12V voltage source 4 and photoconductive resistance 5.Windshield body 1 is three
Rotating fields include first glassy layer the 11, second glassy layer 12 and be glued at first glassy layer the 11, second glassy layer 12 it
Between dimming liquid crystal film 13, dimming liquid crystal film 13 use applying the biggest light transmittance of voltage the lowest, when not applying voltage
Form for full impregnated light.Controller 3 have employed the ECU of vehicle self, and light sensor 4 may be installed vehicle body etc. and is positioned at
The position in the outside of windshield body 1, for detecting the intensity of illumination of outside vehicle environment.Light sensor 2 and control
Device 3 input interface processed connects, and controller 3 output interface is connected with 12V voltage source 4.Light intensity is believed by light sensor 2
Number sending controller 3 to, controller 3 compares the size of light intensity signal and the predetermined value received, when light intensity signal is more than pre-
During definite value (3000lm), controller 3 controls 12V voltage source 4 and opens；When light intensity signal is less than or equal to predetermined value (3000lm)
Time, controller 3 controls 12V voltage source 4 and cuts out.Photoconductive resistance 5 uses intensity of illumination to increase the form that resistance reduces,
The illumination that the position of the inner side being arranged on the windshield bodies 1 such as vehicle instrument desk surface is experienced with measurement driver is strong
Degree, dimming liquid crystal film 13, photoconductive resistance 5 and 12V voltage source 4 are connected in series.When external environmental light is powerful in 3000lm
Time, ECU controls 12V voltage source 4 and opens, and original dimming liquid crystal film 13 does not apply voltage, and light is all through gear
Wind glass body 1, photoconductive resistance 5 receives strong illumination resistance and reduces, and dividing potential drop reduces, and puts on dimming liquid crystal film 13
Voltage increase, windshield body 1 gradually decreases printing opacity, and photoconductive resistance 5 resistance is gradually increased and tends towards stability, half
The windshield body 1 of printing opacity makes driver obtain comfortable light environment after filtering out some light, and driving safety obtains
Ensure.When vehicle sails dark environment into from brighter environment, just having started dim, photoconductive resistance 5 resistance is gradually
Increasing, the voltage putting on dimming liquid crystal film 13 reduces, and windshield body 1 is gradually increased printing opacity and becomes to adapt to environment
Change.When extraneous light intensity signal is less than predetermined value (3000lm), controller 3 then controls 12V voltage source 4 and disconnects, gear
The complete printing opacity of wind glass body 1.
