Abstract

The invention relates to a voice coil motor, which includes a fixed body with a first accommodation cavity, a movable barrel movably accommodated in the first accommodation cavity, at least two upper rolling elements and at least two lower rolling elements. The fixing body includes at least one upper groove and at least one lower groove. The at least two upper rolling elements and at least two lower rolling elements are respectively arranged in the at least one upper groove and the at least one lower groove and are pressed against the movable cylinder so that the at least two upper rolling elements And frictional force can be generated between at least two lower rolling parts and the movable barrel. The invention also relates to a camera module with the voice coil motor and a portable electronic device with the camera module.

Description

technical field [0001] The invention relates to a voice coil motor, a camera module with the voice coil motor and a portable electronic device using the camera module. Background technique [0002] A voice coil motor (Voice Coil Motor, VCM) with the advantages of small size, low power consumption and low price is suitable as an actuator in electronic products (such as digital cameras, mobile phones, video cameras, etc.). [0003] A common voice coil motor mainly includes a fixed frame and a movable barrel movably installed in the fixed frame. The barrel is used to install components such as lens barrel or focusing lens group. Under the condition of being powered on, the voice coil motor drives the movable barrel to move relative to the fixed frame, thereby changing the distance between the lens barrel or the focusing lens group and the image sensor, thereby realizing the focusing function. [0004] When the above-mentioned voice coil motor is finished focusing, it must con...
