Abstract
A driving mechanism for driving an optical element is provided, including a fixed module, a movable module, and a drive assembly disposed on the fixed module and the movable module. The drive assembly includes a magnet and a coil for moving the movable module relative to the fixed module along a first axis. Specifically, the central axis of the magnet extends through a part of the coil and is offset from the center of the coil, wherein the central axis is perpendicular to the first axis.
Claims20
A driving mechanism, comprising:
- a fixed module;
- a movable module movably connected to an optical element with an optical axis, wherein the movable module is movable relative to the fixed module;
- a drive assembly driving the movable module to move relative to the fixed module, wherein the drive assembly comprises a coil and a first magnet;
- and
- a magnetically conductive element comprising a magnetically conductive material, wherein the magnetically conductive element corresponds to the first magnet;
- wherein the first magnet comprises a first surface and a second surface both perpendicular to the optical axis, the first surface and the second surface face in opposite directions, the first surface faces the coil, and the second surface faces the magnetically conductive element, and
- wherein when viewed from the optical axis, the first magnet, the magnetically conductive element, and the coil at least partially overlap each other, and the first magnet is located between the coil and the magnetically conductive element.
