Embodiment Construction

[0027] The core of this specific embodiment is to provide a zoom lens, which can realize the zoom effect while satisfying the miniaturization of the camera head, and solves the difficult problem in this field at the present stage.

[0028] Hereinafter, the embodiment will be described with reference to the drawings. In addition, the examples shown below do not limit the content of the invention described in the claims in any way. In addition, the whole content of the structure shown in the following embodiment is not limited to what is necessary for the solution of the invention described in the claim.

[0029] The main working principle of the zoom lens provided in this specific embodiment is: the focal length of the lens 1 is changed by changing the temperature of the lens 1, thereby realizing the function of automatic zooming, and at the same time replacing the motor, so that the camera meets the concept of miniaturization. It mainly includes the lens 1 and a temperature c...

Abstract

The invention discloses a zoom lens and an electronic device. The zoom lens comprises a lens, and a temperature control element used for heating or cooling the lens and zooming the lens through deformation caused by the temperature change. In use, the lens is heated or cooled by the temperature control element, so that the lens produces the deformation of thermal expansion and contraction due to the temperature change, and the focal length change of the lens is realized. The process realizes the focal length change through the temperature control of the lens, and does not refer to a motor. The miniaturization design of the lens is realized. According to the zoom lens provided by the invention, camera miniaturization and zooming are realized at the same time, and problems in the field at the current stage are solved.

Description

technical field [0001] The invention relates to the lens field, more specifically, to a zoom lens and electronic equipment. Background technique [0002] In recent years, with the rapid development of science and technology, we have entered the era of intelligent information. Intelligent life is increasingly relying on cameras to realize functions such as object recognition, video calls, and monitoring. [0003] As far as the current market demand for cameras is concerned, high pixel and miniaturization have become the main competitiveness of cameras. At present, in order to further improve the high-definition camera effect of the camera, autofocus is an indispensable function of the camera. As far as the prior art is concerned, the zoom function is mainly realized by the drive of the motor; however, the existence of the motor undoubtedly brings great difficulties to the miniaturization design of the camera. [0004] Therefore, how to achieve the effect of zooming while s...
