Abstract
The utility model relates to electro instant colour changing goggles which are composed of goggle legs, a goggle frame, and liquid crystal lenses. A power supply is respectively arranged on the goggle legs, and the middle part of the goggle frame is provided with a liquid crystal driving movable circuit. A contact type switch is respectively arranged at the connecting positions of the goggle frame and the goggle legs, and the front of the goggle frame is embedded with a photosensitive tube which is connected with the liquid crystal drive circuit, the power supply, the liquid crystal lenses and the contact type power switch. The output end of the liquid crystal driving circuit is connected with the liquid crystal lenses, and the photosensitive tube is embedded at the top left corner of the left frame of the goggle frame. The liquid crystal lenses of the utility model can automatically discolor according to the light intensity, a driver can react quickly for the light rays, and thus the traffic accident can be avoided.
Description
The utility model relates to a kind of eye-protective system, particularly a kind of safety goggles.
When motor vehicles meet at night, dazzling light makes both sides driver can not normally observe the road surface, influence is driven, traffic hazard easily takes place, though, have some about the automobile meeting automatic device for changing light, but, because relate to the transformation of auto production line, and automaker is numerous, even indivedual vehicle adopts also can't change the status quo.
Chinese patent instructions CN2370438Y discloses a kind of electricity and has caused the instant color-changing protective glasses, and this protective glasses can be realized changing colour of lens according to the power of ring mirror light.But this safety goggles is arranged in the photographic hole at picture frame middle part owing to photosensitive tube, and the light of the other side's automobile is penetrated from driver's left side, the light that photosensitive tube receives is less relatively, output signal is just little, the sensitivity that detects reduces, the reaction of liquid crystal lens is fast inadequately, makes the driver rapid inadequately to the reaction of light.
The purpose of this utility model provides a kind of not only liquid crystal lens can be according to the light intensity automatic color-changing, and can make the driver to the reaction of light more rapidly electricity cause the instant color-changing safety goggles.
The technical scheme that realizes above-mentioned purpose is: a kind of electricity causes the instant color-changing safety goggles, form by leg of spectacles, spectacle-frame and liquid crystal lens, leg of spectacles is provided with power supply, the middle part of spectacle-frame is provided with liquid crystal display drive circuit, the junction of spectacle-frame and leg of spectacles has the contact switch, the spectacle-frame front is embedded with photosensitive tube, this photosensitive tube links to each other with liquid crystal display drive circuit, power supply, liquid crystal lens and contact power switch, the output terminal of liquid crystal display drive circuit links to each other with liquid crystal lens, and photosensitive tube is embedded in the upper left corner of the left frame of spectacle-frame.
After adopting technique scheme, because photosensitive tube is arranged on the upper left corner of the left frame of spectacle-frame, and during automobile meeting, the light of the other side's automobile is penetrated from the driver left side, thereby the light that photosensitive tube receives is more at the light that the spectacle-frame middle part receives than photosensitive tube, the output electric signal is big, the sensitivity that detects also just obtains improving, and makes the reaction of liquid crystal lens faster, i.e. variable color speeds up, and make the driver, thereby can avoid traffic accident to being swift in response of light as far as possible.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of spectacle-frame of the present utility model;
Fig. 3 is provided with synoptic diagram for power supply on the leg of spectacles of the present utility model;
Fig. 4 is a liquid crystal display drive circuit schematic diagram of the present utility model.
Shown in Fig. 1～4, a kind of electricity causes the instant color-changing safety goggles, form by leg of spectacles 1, spectacle-frame 2 and liquid crystal lens 6, leg of spectacles 1 is provided with battery supply 7, the middle part of spectacle-frame 2 is provided with liquid crystal display drive circuit 3, spectacle-frame 2 has contact switch 5 with the junction of leg of spectacles 1, spectacle-frame 2 fronts are embedded with photosensitive tube 4, this photosensitive tube 4 links to each other with liquid crystal display drive circuit 3, power supply 7, liquid crystal lens 6 and contact power switch 5, the output terminal of liquid crystal display drive circuit 3 links to each other with liquid crystal lens 6, and photosensitive tube 4 is embedded in the upper left corner of the left frame 2-1 of spectacle-frame 2.
As shown in Figure 3, battery supply 7 is contained on the leg of spectacles 1, and this battery supply 7 can adopt lithium battery, during installation, covers power connecting sheet 8 on lithium battery, covers power supply lid 9 then, and gets final product with screw-driving is fixing.
As shown in Figure 4, liquid crystal display drive circuit is made up of custom integrated circuit IC and peripheral components and parts thereof, and the model of IC can adopt 9607.4 pin of integrated circuit (IC) connect the positive pole of photosensitive tube, and the output terminal of integrated circuit is connected with liquid crystal lens.
Principle of work of the present utility model is as follows: when leg of spectacles 1 was launched, the contact of leg of spectacles 1 leading section extruding contact switch 5 made the contact contact, switch 5 closures, liquid crystal display drive circuit 3 is connected, at this moment, the extraneous light of photosensitive tube 4 impressions changes, during high light, photosensitive tube 4 output voltages raise, and the integrated circuit (IC) pulsewidth increases, dutycycle changes, 6 shut-in times of liquid crystal lens prolong, and the opening time shortens, thereby printing opacity is reduced; During the low light level, photosensitive tube 4 output voltages reduce, and the integrated circuit pulsewidth narrows down, and 6 opening times of liquid crystal lens are prolonged, and the shut-in time shortens, and cause printing opacity to increase.Thereby liquid crystal lens can be according to the intensity automatic color-changing of light.When stopping using, leg of spectacles 1 is folded up, contact switch 5 disconnects, and liquid crystal display drive circuit 3 quits work.
Liquid crystal lens 1 of the present utility model adopts double-layer lens, bumps as eyeglass and falls and can because of vacuum in the middle of this eyeglass, encapsulate with seccotine all around as the such disposable fragmentation of eyeglass, and tension intensity is good, and double-deck encapsulation eyeglass can not break simultaneously yet.
The utility model makes eyeglass printing opacity conditioned reaction fast (the millisecond order of magnitude) owing to adopt liquid crystal technology, and adjustable extent is big, because human eye has the vision retention characteristics, by the interval time that the control eyeglass opens and closes, transmittance is changed, eyes just can be experienced the continuous variation of light.
