Camera module group and portable electronic device

Abstract

The present invention provides a camera module comprising at least a lens module, a photosensitive element, at least a step motor, a cam slope structure and a stop catch component; the lens module comprises a lens cone and lenses arranged in the lens cone; a cam pin protrudes from the head face of the lens cone near the image side; the photosensitive element and the lens module are arranged correspondingly; the step motor comprises a stator and a rotor which is driven to rotate by the stator; the cam slope structure is fixedly connected with the rotor and rotates along the rotation of the rotor; the cam pin of the lens cone supports the cam slope structure; the stop catch component is used for stopping the rotation of the lens module.

Description

technical field [0001] The present invention relates to a camera module with focusing function, and to a portable electronic device with the camera module Background technique [0002] With the development of the camera industry, camera modules are widely used in camera devices for various purposes. Camera modules are built into various portable electronic devices, such as mobile phones, camcorders, and computers, and are widely used by many consumers. of favor. A camera module usually includes at least one lens module, and a photosensitive element opposite to the lens module. A lens module may include one or more lenses, and a lens barrel that houses the lenses. The center of the photosensitive element is located on the optical axis of the lens module. When focusing, drive the relative displacement of the lens module and the photosensitive element to find a focus position (viewfinder position) with the best resolution. When zooming, the distance between the lenses in th...

Problems solved by technology

[0003] When the camera module focuses or zooms, a typical way is to make the lens module rotate and move back and forth relative to the photosensitive element, for example, relying on the screw structure of the lens barrel and the carrier of the photosensitive element, so that the optical axis of the lens module It may be due to factors such as the matching error of the thread structure that the rotation deviates from the center of the photosensitive element, thereby reducing the working performance of the camera module
