Description
Technical field
The present invention relates to glass processing and manufacturing technology field, in particular a kind of solar protection devices, vehicle, glass sunshading method.
Background technology
In vehicular drive, ambient light irradiance varies, as the noon sunny, light was too strong, in tunnel, in rainy day or night light too a little less than, and often have the situation of travelling in face of the sun, the sunlight that now sees through vehicle window can directly enter driver's eyes, in the time that in visual field, strong and weak optical contrast ratio is very high, human eye is not just differentiated the information of the low light level, drives environment around owing to dazzling the eyes not see, and easily causes traffic accident.Therefore, in vehicle, need to arrange shade.
In order to realize shading object, in prior art, can adopt following two kinds of modes:
The first, in car, front window top configuration sun shield, while needing shading turns down this sun shield, and the used time can not roll up, and to avoid direct sunlight eyes, thereby can improve driving sight to a certain extent.But anti-dazzle device need to occupy the space in car, and aesthetic property is poor; In addition chaufeur need to, according to the light conditions position of manual regulation sun shield at any time, be unfavorable for safe driving.
The second, in plastics intermediate coat (as PVB film) in car in the Windshield interlayer on front window top, add color, so that corresponding Windshield becomes is opaque, thereby can avoid direct sunlight eyes, reach shading object.But owing to being with coloured plastics intermediate coat to exist all the time, even therefore weak without shading in the situation that at light, Windshield be still opaque, cannot make extraneous light see through with light intensity in raising car, be that this kind of mode cannot regulate, thus poor practicability.
Similarly, in the use procedure of other glass (as: building glass), sometimes also needing to carry out sun-shading, there are the problems referred to above in it equally.
Therefore, how to realize simply and effectively the printing opacity of glass is regulated and just becomes one of those skilled in the art's problem demanding prompt solution.

In the present embodiment, user can regulate described regulating control to reach the simple object of effectively adjusting light intensity in car by manual or voice-operated mode.
Compared to Figure 1, shown in figure 5, present embodiment also provides a kind of solar protection devices, and it can also comprise:
Sensor 510, is arranged on described glass 100, for obtaining current intensity signal;
Controller 530, connects described sensor 510 and described regulating control 400, for regulating according to regulating control 400 described in current intensity signal control.
Particularly, described sensor 510 is light intensity sensor, and it can be arranged on inside face, outside face or the inside of glass 100, thereby can obtain the intensity signal at corresponding aspect place.
Described controller 530 can be micro controller system, digital signal processor etc., and shown in figure 6, it specifically can comprise:
Extraction unit 531, connects described sensor 510, for extracting described intensity signal;

Acquiring unit 534, connects described regulating control 400, for obtaining the status information before regulating control 400 regulates, to obtain the voltage before adjusting;
Comparator 535, connects described call unit 533 and acquiring unit 534, for calculating the difference between the voltage before voltage and the adjusting after described adjusting;
Adjustment unit 536, connects described regulating control 400 and comparator 535, for according to described difference, controls described regulating control 400 and regulates.
Particularly, the working process of described controller 530 is as follows:
1) before using, store in advance the corresponding relation of each intensity signal and the voltage that need provide for each intensity signal power supply 300 in memory cell 532, this voltage is the voltage after adjusting, and it is corresponding with the light transmittance of expectation.
2) after sensor 510 obtains current intensity signal, extraction unit 531 extracts current intensity signal from sensor 510, and this current intensity signal is sent to call unit 533.
3) call unit 533 calls the voltage after the adjusting corresponding with described current intensity signal from memory cell 532, and the voltage after regulating is sent to comparator 535.When voltage after regulating control 400 makes power supply 300 provide for polymer dispersed liquid crystal film 200 voltage by adjusting is described adjusting, can ensure that the light transmittance of correspondence position meets user's requirement.
4) status information of acquiring unit 534 from regulating control 400 obtains it and regulates, and then obtain the voltage before the adjusting that power supply 300 provides for polymer dispersed liquid crystal film 200, and the voltage before regulating is sent to comparator 535.
5), after comparator 535 obtains the voltage before voltage and the adjusting after adjusting, calculate both differences.In the time that the light transmittance of glass correspondence position need to reduce, pdlc film need to regulate to opaque state from pellucidity, thereby the voltage after regulating is less than the voltage before adjusting; In the time that the light transmittance of glass correspondence position need to improve, pdlc film need to regulate to pellucidity from opaque state, thereby the voltage after regulating is greater than the voltage before adjusting.
6) adjustment unit 536 obtains this difference from comparator 535, thereby controlled adjuster 400 regulates power supply 300, and the voltage that the power supply 300 after regulating is provided for polymer dispersed liquid crystal film 200 is the voltage after described adjusting.In the time that the light transmittance of glass correspondence position need to reduce, because the voltage after regulating is less than the voltage before adjusting, therefore regulating control 400 need to reduce the voltage that power supply 300 provides for polymer dispersed liquid crystal film 200; In the time that the light transmittance of glass correspondence position need to improve, because the voltage after regulating is greater than the voltage before adjusting, therefore regulating control 400 need to improve the voltage that power supply 300 provides for polymer dispersed liquid crystal film 200.
Control by controller 530 to regulating control 400, makes regulating control 400 regulate power supply 300 so that power supply 300, for polymer dispersed liquid crystal film 200 provides suitable voltage, finally meets the light transmittance of correspondence position.
The corresponding relation of described intensity signal and described voltage can preset, and can change at any time.
It should be noted that, in the time that sensor 510 is positioned at the different surfaces of glass, the intensity signal difference that it obtains, therefore corresponding voltage is also different.
Further, described solar protection devices can also comprise: the speech player 550 being connected with described controller 530, in the time that described controller 530 is controlled described regulating control 400 and regulated, play described current intensity signal and adjusting information, to inform in time user.

(2) controller 530 obtains the voltage before adjusting by regulating control 400, and obtains the voltage after adjusting according to current intensity signal;
(3) voltage of controller 530 according to the voltage after regulating and before regulating is poor, and controlled adjuster 400 regulates power supply 300; Described speech player 550 can carry out corresponding voice broadcast simultaneously.
The present embodiment obtains current intensity signal by sensor 510, and by controller 530 controlled adjusters 400, polymer dispersed liquid crystal film 200 is provided the automatic adjusting of voltage swing, thereby without user's manual regulation, safety is higher.
It should be noted that, in the time of the solar protection devices using shown in Fig. 1 or Fig. 5, as be applied in vehicle, can be in the different glass of vehicle or the diverse location of same glass described polymer dispersed liquid crystal film is set respectively, the respectively corresponding regulating control of each polymer dispersed liquid crystal film, a power supply, a sensor, multiple polymer dispersed liquid crystal films can shared control unit and speech player, thereby can be according to different needs, realize the different light transmission capacities of different glass or same glass diverse location.
