Abstract

The invention provides a lens driving device, an imaging device and a mobile terminal. The lens driving device includes a housing and a base. The housing cover is arranged on the base and forms an accommodating space with the base. The lens driving device also includes: a lens holder arranged in the accommodating space, and the lens holder is movably arranged inside the accommodating space ; The elastic support component is supported between the lens holder and the base or between the lens holder and the shell, and the elastic support component is energized to deform at least a part of the elastic support component and drive the lens holder to move along the Z-axis direction; Sensing part; detecting part, one of the sensing part and the detecting part is arranged on the lens base, the other of the sensing part and the detecting part is arranged on the base, and the detecting part is arranged corresponding to the sensing part. The invention solves the problem of poor service performance of the voice coil motor of the camera device in the prior art.

Description

technical field [0001] The present invention relates to the field of camera devices, in particular to a lens driving device, a camera device and a mobile terminal. Background technique [0002] Video cameras or cameras usually use lenses with adjustable focal length or auto-focus, and the adjustment process is to change the position of the lens, and a drive motor is usually used to drive the lens to move. At present, the automatic focusing of the camera of the hand-held camera device—especially the camera of the mobile phone is basically completed by a voice coil motor (Voice Coil Motor, VCM), which is a system composed of a coil and a magnet. The coil after electrification will be subjected to electromagnetic force in the magnetic field. Due to the action of electromagnetic force, the winding carrier will move linearly along the optical axis of the lens (that is, the Z axis), and the winding carrier will eventually stay between the ring coil and the driving magnet. The pos...
