Lens module

Abstract

The invention provides a lens module, which comprises an optical component, a holding shell and an image sensor. The image sensor is provided with a sensing face, the optical component and the image sensor are arranged oppositely and are both held in the holding shell; the lens module also comprises an optical tilt-angle sensing component, a controller and at least one adjustment component, the optical tilt-angle sensing component detects the verticality of the optical axis of the optical component corresponding to the sensing face of the image sensor, the adjustment component is made from anelectrostrictive material and is connected between the optical component and the holding shell, and the flexible deformation of the electrified adjustment component can change the verticality of the optical axis of the optical component corresponding to the sensing face of the image sensor; the controller, the optical tilt-angle sensing component and the adjustment component are electrically connected, the controller can control the adjustment component to flex radially along the lens module according to the deflection level of the optical axis of the optical component detected by the opticaltilt-angle sensing component. In the invention, the imaging quality is improved through flexibly adjusting the verticality of the optical axis of the optical component corresponding to the verticality of the sensing face of the image sensor by the adjustment component.

Description

technical field [0001] The invention relates to a lens module. Background technique [0002] At present, while consumers require photographing devices, such as digital cameras and digital video cameras, to have better photographing quality, they also hope that these photographing devices are smaller and thinner. [0003] However, as the size of the lens module becomes smaller and smaller, in order to ensure the image quality, it is necessary to strictly control various factors that affect the image quality. Now when the optical assembly of the zoom lens module zooms, the cooperation between the drive shaft of the stepping motor and a small part of the side wall of the optical assembly is often used to drive the optical assembly to move along the optical axis. However, because only a small part of the side wall of the optical component is under force, the force on the optical component is uneven, so after moving, it will affect the perpendicularity between the optical axis o...

However, since only a small part of the side wall of the optical component is under force, the force on the optical component is uneven, so after moving, it will affect the perpendicularity between the optical axis of the optical component and the sensing surface of the image sensor, thereby affecting image quality
