Automatic divisional sunglasses-adjusting frame structure

Abstract

The invention discloses an automatic divisional sunglasses-adjusting frame structure, comprising a spectacle frame and two glasses legs connected with the two ends of the spectacle frame, a battery is arranged on the spectacle frame or the glasses legs, a photoelectric sensing module is arranged on the spectacle frame or the glasses legs to induce the external irradiation angle and illuminance of the sunlight, a control module is arranged on the spectacle frame or the glasses legs to control the transmittivity of the liquid crystal lens in the spectacle frame to change following the external illuminance and the incident angle, the battery is electrically connected with the control module and the photoelectric sensing module, the photoelectric sensing module is connected with the control module, the photoelectric sensing module is arranged on the outside and / or upside of the spectacle frame or the glasses legs which can induce the external illuminance. The automatic area sunglasses-adjusting frame structure provided by the invention can automatically adjust the transmittivity of the liquid crystal lens to change gradually in a variable gradient mode to automatically adjust the degree of light and shade of the liquid crystal lens according to the position and the intensity of sunlight.

Description

technical field [0001] The invention relates to a frame structure of sunglasses, in particular to a frame structure of fully automatic partition adjustment sunglasses. Background technique [0002] At present, along with the continuous improvement of people's living standards, more and more people protect their eyes from being stimulated by extraneous glare in summer when the hot sun is relatively strong. However, the most commonly used sunglasses with relatively low cost are the spectacle lenses with a single transmittance, and the transmittance of the spectacle lenses cannot be adjusted according to the intensity of sunlight during use, which has a certain degree of protection for the user's glasses. limitations. Currently on the market, color-changing sunglasses can be adjusted by adjusting the transmittance of eyeglass lenses. There are many kinds of such color-changing sunglasses, one of which contains a relatively large electronic circuit to control the change of the ...

AI Technical Summary

Problems solved by technology

These electronic components increase the cost and current consumption of the whole device, and the cost is relatively high. Due to the large size, this kind of sunglasses is relatively large, heavy and expensive as a whole

The second is to use electronic circuits to provide DC signals to the liquid crystal lenses. These electronic components are not used, but because ions will move when a DC signal is applied to the liquid crystal lens, resulting in discoloration points, which greatly shorten the life of the liquid crystal lens.

The third is photochromic sunglasses on the market, which do not contain electronic devices. Instead, a chemical coating is applied to the liquid crystal lens. When the glasses are exposed to ultraviolet light, the chemical coating of the liquid crystal lens produces chemical reaction, a chemical reaction that causes the lenses to darken

Compared with the time required for human pupils to adjust to adapt to changes in lighting, these response times are too long. When encountering sudden changes in ambient light, such as entering a room or tunnel, the transmittance of the lens cannot be automatically adjusted quickly, resulting in Diminished vision, unable to see the surrounding environment clearly
