Description

Light Control Solar LCD Eye Mask

Technical field:

The utility model relates to the field of tool goggles, in particular to a light-controlled solar liquid crystal goggle which can adjust the visibility according to the environment and is easy to carry.

Background technique:

At present, the traditional goggles used by workers in strong light workplaces mainly consist of a face shield 1, a protective glass 2 and a handle 3, as shown in FIG. 1 . Its purpose is to block the damage to the eyes caused by strong light and the damage to the face caused by splashes when workers are electric welding or welding certain items. The protective glass used in the eye mask is dark, and the color depth cannot be changed, and the light transmittance cannot be adjusted. The disadvantage of this traditional eye mask is that the light transmittance cannot be adjusted with the change of the environment. When in use, if the light intensity is not enough or when spot welding is required, the protective glass still maintains a low light transmittance, which brings inconvenience to the user's operation. If the glass with high transparency is used, it cannot protect the user's eyes when the light is strong. In addition, since the operator needs to free his hand to hold the handle to maintain its position during use, it is inconvenient to operate and use. And the occupied area of this traditional blindfold is bigger, is not easy to carry greatly.

Invention content:

The purpose of the utility model is to provide a more convenient light-controlled solar liquid crystal eye mask by improving the prior art.

The utility model is mainly composed of a mask and a protective glass. There is also a liquid crystal screen inside the protective glass. The liquid crystal screen is connected to the output end of the drive circuit. The power is provided by the battery after absorbing energy from the solar panel on the mask. And the boost circuit is connected to the drive circuit.

Both sides of the mask are provided with hooks, and the hooks are connected with lanyards. There is a movable nose bridge in the middle of the mask. The left and right sides of the mask form a 140° angle. A zipper is arranged in the middle of the lower part of the mask.

After adopting the above method, the utility model can be powered by solar energy, and the strong light can be temporarily controlled by the light control circuit, and the light transmittance of the liquid crystal screen can be adjusted according to the light intensity in the actual environment, so as to protect the eyes at all times, and also It is convenient to see the specific position clearly during spot welding. And the adopting of hook and lanyard can bring great convenience to the operator, no longer need to hold the handle with hand to keep the position of eye mask. Moreover, the whole can be folded, which can effectively reduce the storage area and is easy to carry.

Detailed ways:

As shown in Fig. 2 and Fig. 3, the utility model mainly is made up of mask 1 and protective glass 2, is also provided with liquid crystal screen 3 inside protective glass 2, and liquid crystal screen 3 is connected in the output terminal of driving circuit 40, and power supply is provided by mask 1. The solar panel 11 on the solar panel absorbs energy and stores it in the battery for supply. The power supply 10 is connected to the driving circuit 40 through the control circuit 20 and the boost circuit 30 .

Both sides of the mask 1 are provided with a hook 12, and a lanyard 13 is connected to the hook 12. A movable nose bridge 14 is arranged in the middle part of the mask 1 . The left and right sides of the mask 1 form an angle of 140°. A slide fastener 15 is arranged in the middle of the lower part of the mask 1 .

During use, first stand up the movable bridge of the nose 14 of the utility model, be clamped in the appropriate position of the bridge of the nose, then hang the lanyards 13 on both sides on the ears, so that the utility model has just been fixed on the face. The face shield 1 is made of plastic, the lower part is a plane, flexibly connected by a zipper 15, and the liquid crystal screen 3 is slightly inclined outward, as shown in Figure 4, to increase the field of view; the photoresistor is placed between the protective glass 2 and the liquid crystal screen 3 In the photosensitive tube 4 on the top, the interference of ambient light is effectively prevented; a protective film 21 is pasted on the protective glass 2 to prevent ultraviolet rays from penetrating and reflecting light. When in use, the left and right sides of the mask 1 form an angle of 140°, so that the mask 1 fits the face more closely and further increases the width of the field of view. Before the welding-related work starts, the liquid crystal screen 3 has high transparency, and the operator can clearly see the position where welding or spot welding needs to be started. Once the welding or spot welding work starts, the circuit starts to work and controls the liquid crystal screen 3 . As shown in Figure 5 and Figure 6, the solar panel absorbs solar energy and converts it into electrical energy and stores it in the battery of the circuit, which becomes the power supply 10 of the circuit. Afterwards, the resistance changes to control the initial voltage of the booster circuit 30. After the booster circuit 30, the voltage rises, and the rising range is limited by the Zener tube. A 3V, 6V or 12V Zener tube can be used according to specific usage scenarios. The regulated voltage enters the driving circuit 40, so that the current changes from direct current to alternating current, and the square wave type drives the liquid crystal screen to become dark, and the light transmittance decreases, thereby protecting the eyes. When the strong light disappears, due to the effect of the inductance, the current will not decrease rapidly but gradually weaken, so the circuit will be turned off with a delay of 0.2 to 0.5 seconds to prevent the chaotic control of the circuit caused by the flickering of the strong light.

After use, the zipper at the bottom of the utility model can be unzipped, folded in half along the crease in the center, and can be separated to the size of 1/4 of the original mask, which reduces floor space and is convenient for portable storage.

At the same time, in order to be conveniently applied to various workplaces, the circuit adopts an integrated circuit, and the utility model can also be made into an ordinary glasses type, and the photoresistor and the circuit board are installed in the middle of the glasses, directly in front of the bridge of the nose. The nose bridge bracket is about 5 mm higher than the nose bridge bracket of ordinary glasses. The sun panel is divided into three installation methods: one is installed in the middle of the upper beam of the frame, which widens the upper beam of ordinary glasses; the other is installed at the end of the temple; Third, it is installed below the LCD screen. These two installation methods can be beneficial to the absorption of solar energy. For the sake of convenience, this device also can take the mode of replacing the battery without the solar panel. At the same time, the regulator tube in the circuit can also be replaced with a potentiometer, so that users can adjust the voltage at any time to achieve the purpose of changing the transparency of the LCD screen at any time. Users can use it not only in workplaces, but also in daily life. Can withstand the sun.
