Detailed Description

For a full understanding of the objects, features and effects of the present invention, reference will now be made to the following examples taken in conjunction with the accompanying drawings

The new concept, specific structure and the resulting technical effect will be further explained.

Example 1

As shown in fig. 1 to 2, sunglasses include a frame 100 and a liquid crystal lens 200, and further include: a solar panel 110 and a control module 120 disposed on the frame; the solar panel 110 is used for outputting voltage signals with different magnitudes according to the change of the illumination intensity; the control module 120 is electrically connected to the solar panel 110, and is configured to generate a regulation signal according to the voltage signal; the liquid crystal lens 200 is electrically connected to the control module 120 for adjusting the transmittance thereof according to the received adjustment signal.

Specifically, the solar panel outputs voltage signals with different sizes according to the illumination intensity, wherein the voltage signals are low-voltage control signals. When the illumination intensity of the environment is increased, the voltage value of the low-voltage control signal output by the solar panel is increased, and when the illumination intensity of the environment is weakened, the voltage value of the low-voltage control signal output by the solar panel is decreased. It should be noted that solar panel is solar panel's characteristic according to the different voltage signal of illumination intensity output size, just control module can confirm according to signal type and processing requirement to the concrete mode of low-voltage control signal's collection to can adopt the processing mode known in the art to handle, the utility model discloses do not restrict this.

The control module generates a regulating signal according to the low-voltage control signal, wherein the regulating signal is a low-frequency alternating-current voltage signal. When the liquid crystal lens of the sunglasses adopts a liquid crystal lens in a direct display mode, the voltage value of the low-voltage control signal acquired by the control module is larger (namely, the illumination intensity of the environment is strong), the voltage value of the generated low-frequency alternating-current voltage signal is also larger, and the voltage value of the low-voltage control signal acquired by the control module is smaller (namely, the illumination intensity of the environment is weak), and the voltage value of the generated low-frequency alternating-current voltage signal is also smaller.

It should be noted that, the control module generates the processing mode of low frequency alternating voltage signal according to low voltage control signal, can carry out voltage detection to low voltage control signal through voltage detection circuit, and direct current voltage that the pulse power supply circuit in through the control module provided solar panel converts alternating voltage into to and the circuit that reduces the frequency through in the control module handles, can also adopt the processing mode known in the art to handle, the utility model discloses do not restrict to this.

The liquid crystal lens is according to the voltage size of its low frequency alternating voltage signal of receiving, and the distortion angle of its inside liquid crystal also can be different to change the light transmittance, make this sunglasses can be according to the intensity of the illumination intensity of environment and automatically regulated liquid crystal lens transmittance, let the thing that the people who wears this sunglasses saw can not too dark nor too bright, also can avoid the sudden change to give people the uncomfortable that brings, let the user feel very comfortable, reinforcing user experience.

When a user wears the sunglasses to drive an automobile to enter a tunnel in the daytime, the solar panel outputs a low-voltage control signal due to the fact that the illumination intensity of the environment is high before the automobile enters the tunnel, the voltage value of the low-frequency alternating voltage signal generated by the control module is large, the voltage obtained by the liquid crystal lens is large, the liquid crystal lens is made to be black or other colors, and light is prevented from entering human eyes. When getting into the tunnel and after getting into the tunnel, the illumination intensity of environment weakens gradually, the numerical value of the low-voltage control signal of solar panel output reduces gradually, the numerical value of the low frequency alternating voltage signal that control module generated also reduces gradually, leads to the obtained voltage of liquid crystal lens to diminish for the liquid crystal lens becomes bright gradually, increases gradually and gets into the light of people's eye.

In addition, because the adjusting signal is a low-frequency alternating voltage signal with the frequency of 1/60 Hz-1/100 Hz, the frequency of the driving voltage of the liquid crystal lens is greatly reduced, the power consumption of the liquid crystal lens is effectively reduced, the power saving effect is realized, meanwhile, the damage to the liquid crystal lens can be avoided, and the service life is prolonged.

Preferably, the frequency of the adjustment signal is 1/90 Hz.

Preferably, as shown in fig. 1, the solar panel 110 is disposed at a position of a nose bridge of the frame, and the control module 120 is disposed in the position of the nose bridge of the frame, so that the influence of electronic components on the appearance of the sunglasses is reduced to the maximum, and the aesthetic degree of the sunglasses is improved. And the solar panel is arranged on the nose bridge position of the mirror frame, and the sensing direction of the sensing surface for sensing the illumination intensity is the same as the visual direction of human eyes, so that the light energy can be better received, meanwhile, the illumination intensity of light rays irradiating to the human eyes can be more intuitively known, and the transmittance of the liquid crystal lens can be better changed.

As shown in fig. 2, as an embodiment, the solar panel 110 includes a power supply output terminal connected to the power supply input terminal of the control module 120. Solar panel exports the mains voltage of equidimension not according to illumination intensity, only needs the mains voltage of exporting to be greater than control module's operating voltage, can for control module's work provides the power, makes control module carries out work, drives the transmittance is adjusted to the liquid crystal lens to make this sunglasses can remove the battery from.

Further, the control module 120 is an IC chip 4051. Preferably, the minimum operating voltage of the IC chip 4051 is 0.9V, and the minimum operating current is 50 nA. Because the working voltage of the IC chip is low, the sunglasses can use the solar panel with smaller volume, thereby further reducing the influence of the solar panel on the appearance of the sunglasses to the maximum extent and improving the aesthetic degree of the sunglasses.

Furthermore, the charge retention rate of the liquid crystal lens 200 is greater than 98%, so that the charge in the liquid crystal lens can be kept for a certain time without loss after being electrified, the electrified state can be kept for a longer time, the electric energy required by the liquid crystal lens is reduced,therefore, the power consumption is reduced, and the effects of saving electricity and increasing the endurance time are achieved. It should be noted that, when a user wearing the sunglasses is in a tunnel, the control module may always apply a low-frequency ac voltage signal to the liquid crystal lens, but the liquid crystal lens does not need much electric energy to maintain the power-on state at this time, and after leaving the tunnel, the control module may set the value of the low-frequency ac voltage signal to zero and release the electric charge in the liquid crystal lens, so that the liquid crystal lens is instantly converted into black, and ambient light is blocked from entering human eyes. The liquid crystal lens can improve the purity of liquid crystal and the resistivity to 1 × 10¹³Omega cm or more.
