Embodiment Construction

[0024] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0025] First, the working principle of the lens device provided by the embodiment of the present invention is introduced. By changing the flow rate of the fluid on both sides of the film, the film is elastically deformed and the curvature of the film is changed, thereby changing the focal length of the lens device.

[0026] figure 1 Schematic diagram of the structure of the lens device provided by the embodiment of the present invention, figure 2 An exploded schematic diagram of a lens device provided in an embodiment of the present invention, combined with figure 1 and figure 2 As shown, the lens device provided by the embodiment of the present invention includes a first housing 1 , a second housing 2 and a film 3 .

[0027] The first housing 1 has a first through hole 11 for the inflow or outflow of the first fl...

Abstract

The embodiment of the invention relates to a lens device which comprises a first shell, a second shell and a thin film, wherein the thin film is encapsulated between the first shell and the second shell; a first cavity is formed between the first shell and the thin film; a second cavity is formed between the second shell and the thin film; a gap between the first cavity and the second cavity is sealed; after receiving control data generated by a processor, a controller controls a motor to inject quantitative first fluid into the first cavity via a first through hole, so that quantitative deformation of the thin film is increased under the pressure of the first fluid, and the curvature of the thin film is increased so as to adjust the thin film to achieve the aim of narrowing and controlling the focal distance; second fluid in the second cavity flows out of a second through hole under extrusion of the thin film; or, quantitative first fluid in the first cavity is pumped out by the motor via the first through hole, so that the quantitative deformation of the thin film is decreased under the pressure of the first fluid, and the curvature of the thin film is decreased so as to adjust the thin film to achieve the aim of enlarging and controlling the focal distance; the second fluid flows into the second cavity via the second through hole while stretching the thin film.

Description

technical field [0001] The invention relates to the technical field of optical devices, in particular to a lens device. Background technique [0002] With the advancement of science and technology, the increase of electronic devices, people spend more and more time facing electronic screens, and various incorrect eye habits, the damage to the eyes is increasing, and people's demand for glasses is increasing. more. [0003] Human eyes need different focal lengths when viewing objects at different distances, but the focal lengths of existing lens devices used for glasses are fixed and cannot be adjusted. Users use the same focal length when viewing objects at different distances, which brings discomfort to the human eye. The user experience is extremely poor. Contents of the invention [0004] The object of the present invention is to address the defects of the prior art and provide a lens device that can adjust the curvature of the film by adjusting the amount of change o...
