Mechanism for achieving focusing by changing liquid crystal curvature

Abstract

The invention discloses a mechanism for achieving focusing by changing the liquid crystal curvature. The mechanism comprises a brake, an optical lens, a liquid crystal lens and a top support. The optical lens and the liquid crystal lens are coaxially arranged. The brake comprises a base, an adjustable substrate and a driving mechanism. The liquid crystal lens is arranged on the top end of the base. The optical lens is arranged in the base and corresponds to the liquid crystal lens. The driving mechanism is connected with the adjustable substrate to provide driving force for driving the adjustable substrate to up-down move. The top support is arranged between the liquid crystal lens and the optical lens. A ring which is concentrically arranged with the liquid crystal lens is arranged in the center of the top support. According to the invention, through the pushing of the adjustable substrate, the ring of the top support is in contact with or squeezes the liquid crystal lens which is filled with liquid and after the squeezing, the liquid flows to form a new curvature, so the bigger the curvature becomes, the nearer the shootable distance becomes, thereby achieving near-distance focusing.

Description

technical field [0001] The invention relates to a lens, in particular to a mechanism for realizing focusing by changing the curvature of liquid crystals. Background technique [0002] The macro lens does not mean that it can only shoot close-ups, but it can shoot closer than ordinary lenses. The existing mobile phone cameras generally can only shoot from infinity to 6CM. An existing macro lens achieves focusing by changing the curvature of the liquid crystal, which changes the curvature of the liquid crystal through an electric current. This kind of macro lens consumes more power, and second, there are many circuits, which makes assembly inconvenient and easy. error occured. [0003] In view of this, the designer aimed at the many defects and inconveniences caused by the imperfect structural design of the above-mentioned macro lens, and deeply conceived, and actively researched and improved the trial production to develop and design the present invention.
