Abstract

The invention relates to a lens with a photosensitive assembly withdrawing function. The lens with the photosensitive assembly withdrawing function comprises a substrate, a photosensitive assembly, a lens cone, a lens and a withdrawing mechanism. The photosensitive assembly can be arranged on the substrate between an acting position and a withdrawing position in a reciprocating motion mode by the aid of the withdrawing mechanism. When the photosensitive assembly is located at the acting position, the lens cone is located at a first position where the distance between the lens cone and the substrate is large, and the optical axis of the lens and the photosensitive assembly are intersected. When the lens cone moves to a second position where the distance between the lens cone and the substrate is small, the photosensitive assembly moves to the withdrawing position, and the optical axis of the lens and the photosensitive assembly are not intersected. Thus, compared with the prior art, the thickness of the lens after the lens is contracted is small, and thereby the thickness of a camera which is provided with the lens can also be small. Furthermore, the lens is simple in structure, and easy to manufacture and assemble.

Description

technical field [0001] The invention relates to the lens of a camera, in particular to a lens whose photosensitive component can retreat away from the optical axis of the lens by a retraction mechanism when the lens shrinks toward the inside of the camera body, so that the thickness of the lens after shrinking is smaller. Background technique [0002] The lenses of today's cameras usually have a retractable design, so that the lens barrel provided with the lens group is extended out of the camera body when taking pictures, and the lens barrel is retracted into the body when not taking pictures. When the lens shrinks, the lens group and some optical components in the lens barrel move straight along the optical axis of the lens group toward the photosensitive component (such as a charge coupled device, Charge Coupled Device, CCD for short) in the body. After the lens is fully retracted, the lens The group, these optical components and the photosensitive component are stacked, ...
