Description

Automatic color-changing vehicle glare proof mirror

Technical field

The present invention relates to a kind of vehicle glare proof mirror, relate in particular to a kind of automatic color-changing vehicle glare proof mirror.

Background technology

In the vehicle ' process, daytime extraneous strong sunlight or evening meeting opposite vehicle discomfort dazzle, all can make the personnel that control produce the phenomenon of dazzling the eyes, bring hidden danger to traffic safety.The device major part that is used for automobile sun-shading at present is opaque sun shield, during daytime sunlight direct projection, sun shield is put down, but when blocking sunlight, also blocked the personnel's that control sight line, and owing to the height of controlling personnel differs, the height of sun shield is non-adjustable again, and sun shield is too high, does not have the effect of sunshade, sun shield is too low, can obstruct the view again.

In order to solve discomfort dazzle during meeting in evening, " the automobile-used Electrocontrolled color change plate " that has a kind of TN of utilization LCDs to manufacture responded to the variation of extraneous light, the transmitance of control light by photosensor.When not having extraneous high light, eyeglass is bright attitude, and when sensing high light, eyeglass is dark attitude, realizes the dizzy effect that disappears.But be subjected to the influence of LCDs polaroid transmitance, the transmitance of its eyeglass when not switching on bright attitude is less than 45%, and eyeglass is too dark, is unfavorable for the safety when drive a vehicle evening.

Summary of the invention

The object of the present invention is to provide a kind of automatic color-changing vehicle glare proof mirror, solve the problem that the orthodox car sun shield obstructs the view, can be according to the variation of extraneous light, the transmitance of the automatically regulating eyeglass of rapid nature.

The present invention is achieved like this, it comprises circuit card, photosensor, CPU, adaptor union, battery, switch, color-changing lens, it is characterized in that circuit card connects photosensor, CPU, adaptor union, battery and switch respectively, adaptor union connects color-changing lens, described color-changing lens is made up of 5 layer materials, is respectively glass, vertical orientation material, negative liquid crystal from top to bottom and adds dyestuff eyeglass, vertical orientation material, glass.

The preferred solar cell of described battery, lithium cell or nickel-cadmium cell.

Color after the described color-changing lens deepening is black or blueness.

Described color-changing lens transmitance is controlled between the 5%-80%.

The variation of described color-changing lens light transmittance changes automatically with extraneous light intensity.

The speed of response that described color-changing lens light transmittance changes is between 0.02 second to 40 seconds.

Advantage of the present invention is: adopt negative liquid crystal to add the color-changing lens of dyestuff, do not need to use polaroid, solved existing Electrocontrolled color change plate transmitance problem on the low side, transmitance can reach more than 80%.

The specific embodiment

As shown in Figure 1, the present invention is achieved like this, circuit card 1 connects photosensor 2, CPU3, adaptor union 4, battery 5 and switch 6 respectively, adaptor union 4 connects color-changing lens 7, described color-changing lens 7 is made up of 5 layer materials, is respectively glass, vertical orientation material, negative liquid crystal from top to bottom and adds dyestuff eyeglass, vertical orientation material, glass, and photosensor 2 is welded on the described circuit card 1, by the intensity of induction light, output signal is given to CPU3; CPU3 nation fixes on the circuit card 1, and the voltage input end of this CPU3 links to each other with the voltage output end of battery 5 by described circuit card 1, and the control voltage output end of this CPU3 links to each other with described color-changing lens 7 by described circuit card 1.

As shown in Figure 2, solar panel 8 is both as the power supply of late-class circuit, provide the printing opacity reference as photo-sensitive cell for late-class circuit again, the light intensity signal 9 of output uses for the back level, when regulating light intensity signal 9, can change the light transmittance of color-changing lens 7 under this light intensity, when light intensity is not enough to drive color-changing lens 7, color-changing lens 7 is a pellucidity, and circuit is simple, need not extra battery.

As shown in Figure 3, common alkaline battery 10 is for complete machine provides electric energy, tilt switch 11, and power supply opening when sun shield puts down, voltage stabilizing IC12 plays pressure stabilization function.Photosensor 13 provides the printing opacity reference for late-class circuit.Can change the light transmittance of sun shield according to signal 14 powers.Power work when it is characterized in that sun shield puts down, but all-weather service (but needing to change battery).

As shown in Figure 4, solar panel 15 provides constant-current charge for behind Charge Management IC17 rechargeable battery 18; When battery was full of, indicator lamp 16 was bright, made rechargeable battery be in full state so repeatedly.Late-class circuit is with figure three.But all-weather service need not to change battery.

As shown in Figure 5, an electrode is connecting public pole plate (COM), and another is connecting the cond of character field (SEGMENTS).When the voltage on being applied to two electrodes of color-changing lens was zero, color-changing lens was clear state.Voltage on two electrodes is greater than the threshold voltage of color-changing lens, and then this character field just shows.If use the direct drive color-changing lens, will cause the nonvolatil damage of display unit, thus be added in the necessary punctuated turning over polarity of voltage on the character field, so that the average voltage that is added on the character field is 0.Adopt the MCU of sequence number 16 to produce this waveform that meets the demands to drive color-changing lens for this reason.Power unit 19 is for MCU20 provides electric energy, and MCU20 produces waveform and sees Fig. 6 on two pin 21,22, and the waveform that the cycle of 1/1Duty, 1/1Bias changes is to drive sun shield color-changing lens 7.Prime light intensity signal 23 produces similar waveform with the dutycycle that changes pin 21,22 or the method for frequency after MCU20 handles, see Fig. 7.
