Embodiment Construction

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses an imaging lens and a mobile device, the imaging lens comprises a lens barrel, a first lens group and a second lens group, the first lens group and the second lens group are movably installed on the lens barrel along the optical axis direction, when the imaging lens works, the first lens group and the second lens group move towards the object side, and the first lens group and the second lens group move towards the object side. And when the imaging lens performs focusing at different object distances, the second lens group moves in the directions close to and far away from the first lens group according to working requirements, and the distance between the first lens group and an imaging surface is not changed, so that the distance between the first lens group and the second lens group is adjusted, and clear focusing at different object distances is ensured. When the imaging lens is in a non-working state, the first lens group and the second lens group move towards the image side, and the length and the volume of the imaging lens are reduced, so that the imaging lens can satisfy the use of the mobile equipment as much as possible.

Description

technical field [0001] The invention relates to the technical field of optical lens design, in particular to an imaging lens and a mobile device. Background technique [0002] Existing mobile devices, including mobile phones, tablet computers, notebook computers, etc., are generally equipped with imaging lenses. Among them, the imaging lens in the mobile phone is generally a periscope telephoto lens, and the mobile phone is constantly developing in the direction of miniaturization and light weight, but the periscope telephoto lens is bulky and heavy, which limits the size of the mobile phone. It is difficult to meet the needs of current mobile phone design. Contents of the invention [0003] The main purpose of the present invention is to provide an imaging lens and a mobile device, which aims to solve the problem that the traditional imaging lens is too long and too large to meet the design requirements of the mobile device. [0004] In order to achieve the above object...
