Zoom lens, periscopic lens and mobile phone camera

Abstract

The invention discloses a zoom lens, a periscopic lens and a mobile phone camera. The zoom lens comprises at least three lens groups, a first sleeve and a second sleeve. The first sleeve is provided with a group of directional guide rails, and the lens groups are arranged on the directional guide rails through connecting pieces. The second sleeve is arranged on the first sleeve, the second sleeve rotates along the first sleeve, and moving guide rails corresponding to the lens groups are arranged on the inner wall of the second sleeve. According to the zoom lens, the at least three lens groups, the first sleeve and the second sleeve are arranged, and the second sleeve is rotated to enable the lens groups on the directional guide rails to linearly move along the optical main shaft of the zoom lens, the distance between the lens groups is changed, and a zoom effect is further achieved. Therefore, the zoom and compensation functions of the lens groups can be realized, the position of the focal plane is ensured to be unchanged, the photographing quality is ensured, and the photographing experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of zoom lenses, in particular to a zoom lens, a periscope lens and a mobile phone camera. Background technique [0002] With the development of technology and the improvement of people's living standards, mobile phones have increasingly become an indispensable electronic device in people's lives. Most of the mobile phones currently have a camera function.

However, in view of ...

AI Technical Summary

Problems solved by technology

[0005] The inventor found that the mobile phone camera in the prior art has the problem of being difficult to realize the multi-fold optical zoom function of the mobile phone, which makes it difficult to give the majority of mobile phone users a better photographing experience.
