Abstract
The utility model relates to an electro-controlled colour-changing board for a vehicle, comprising a rotating bracket and a light permeating board installed on the rotating bracket which is installed at the inner upper part of a windshield of the vehicle, and the middle part of the light permeating board is provided with a liquid crystal board, wherein, the two input electrodes of which are connected with the input end of an electro-controlled light measuring device. The colour change of the liquid crystal board of the utility model has high sensitivity, and the change of outside light can not affect the eyes of a driver directly. In addition, an electro-controlled light measuring circuit has simple structure, small size, easy installation and electricity saving.
Description
The utility model relates to a kind of automobile-used Electrocontrolled color change plate, especially is adapted to be mounted within the anti-dazzle device of top in the car windshield.
Self-propelled vehicle is when night running, and two car accent lights that go in the same direction can cause both sides driver's margins of eyelids, for guaranteeing traffic safety, needs both sides driver to close country beam mutually, uses passing light instead, and this causes very big worry by artificial conversion car light concerning the driver of night travel.For addressing this problem, Chinese patent CN2032333U has announced a kind of " High-Speed Automatic light modulation glasses ", and it adopts liquid crystal material to make eyeglass, controls the light transmittance of liquid crystal material through photosensor, oscillator and driving circuit.Though this kind glasses can solve automatically fast light modulation problem, the light-operated circuit that it adopts is complicated, and sensitivity is not high yet, and exists with the glasses form and easily to lose or forget and carry.
Task of the present utility model provides a kind of fixing automobile-used Electrocontrolled color change plate onboard, and it can realize that assurance liquid crystal board color and luster changes thereupon when the ambient light generation steep variation by simple light-operated circuit, solves the problem of artificial conversion car light with this.
For finishing above-mentioned task, the utility model comprises swinging mounting that is installed in top in the car windshield and the light-passing board that is installed on the swinging mounting, middle part at light-passing board also is equipped with liquid crystal board, and the mouth of this a liquid crystal board input electrode and an automatically controlled light measurer joins.When ambient light changed suddenly, electric signal of automatically controlled light measurer output can make the liquid crystal board variable color, at once in order to avoid the variation of ambient light directly causes driver's margins of eyelids.
Described automatically controlled light measurer comprises a photosensitive part, and its mouth joins by clamp resistance and photoelectric commutator, and photoelectric commutator by current-limiting resistance and diode with its signal output.
Liquid crystal board in the described swinging mounting can be arranged to rectangle.
Described liquid crystal board can be set to light transmission state under normal conditions.
Because the utility model adopted automatically controlled light measurer to control the color of liquid crystal board, so it has very high sensitivity, once ambient light is when changing, the color of liquid crystal board changes thereupon, can not make the eyes that ambient light changes directly influences the driver.In addition, automatically controlled light measuring circuit is simple in structure, and volume is especially little, be easy to install, and power saving.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is the utility model appearance structure scheme drawing;
In the accompanying drawing 1, comprise the swinging mounting 1 that is used for the utility model is fixed on top in the car windshield, this swinging mounting is made of two parts, first attaching parts 11, and it can be fixed in the car body by two holes 12 on it.The middle part of attaching parts 11 is by bulb 13 activities, and this bulb can rotate arbitrarily in attaching parts 11 middle part cell bodies.Bulb 13 is fixed a knee 14, and knee 14 passes the protuberance 21 on light-passing board 2 tops, and can go for a stroll bar 14 of light-passing board 2 is rotated.Light-passing board 2 middle parts adhere to lastblock liquid crystal board 3, and two input electrodes 31 of liquid crystal board 3 are joined with the mouth that is fixed on the automatically controlled light measurer 4 on light-passing board 2 tops.
Accompanying drawing 2 provides the schematic circuit diagram of automatically controlled light measurer.This device comprises a photosensitive part R
cR
cAn end and an input angle 1 of power supply E and photoelectric commutator 2 join, the other end is through clamp resistance R
1, join with photoelectric commutator 2 another input angles 14.The output angle 3,9 of photoelectric commutator 2 is connected to a diode D respectively, and its angle 1 is connected to a current-limiting resistance R
2When normality, the mouth of photoelectric commutator 2 is low levels, and this moment, liquid crystal board was a Transparent color, approached white substantially.When extraneous strong illumination, photosensitive part Rc receives high light and makes electric signal of photoelectric commutator 2 conductings output, makes mouth 6 be in high potential, and liquid crystal board promptly can be changed into dark color, makes high light can not directly shine driver's eyes, causes driver's margins of eyelids.When extraneous high light disappeared, photoelectric commutator was in closed condition, makes liquid crystal board return to original state again.The BW series IC products that photoelectric commutator 2 of the present utility model can adopt " 214 research institutes of China Arms Industry chief engineer department " to produce, because its volume is little, sensitivity is adjustable.
