Lens Driving Device

摘要

A lens driving device includes a housing having a base, an upper cover engaged with the base, and a receiving space formed by the base and the upper cover; a permanent magnet mounting base arranged on the base; a permanent magnet fixed on the permanent magnet mounting base; a lens barrel used for holding a lens group therein and movable along a direction parallel to an optic axis of the lens group; a driving coil surrounding an outer surface of the lens barrel, and opposite to the permanent magnet mounted on the permanent magnet mounting base; an anti-shake coil opposite to the permanent magnet mounted on the permanent magnet mounting base; an elastic part suspending and connecting with the lens barrel; an OIS elastic part fixed to an upper surface of the permanent magnet mounting base for restoring the permanent magnet mounting base to a predetermined position.

1. A lens driving device, including:
a housing including a base, an upper cover engaged with the base, and a receiving space formed by the base and the upper cover;; a permanent magnet mounting base arranged on the base; a permanent magnet fixed on the permanent magnet mounting base; a lens barrel used for holding a lens group therein and movable along a direction parallel to an optic axis of the lens group, the lens barrel being received in the permanent magnet mounting base; a driving coil surrounding an outer surface of the lens barrel, and opposite to the permanent magnet mounted on the permanent magnet mounting base; an anti-shake coil opposite to the permanent magnet mounted on the permanent magnet mounting base; an elastic part suspending and connecting with the lens barrel an optic image Stabilizing (OIS) elastic part fixed to an upper surface of the permanent magnet mounting base facing the upper cover and connected to the base for restoring the permanent magnet mounting base to a predetermined position when the permanent magnet mounting base moves along a direction perpendicular to the optic axis.
