Abstract
A driving mechanism is provided, including a fixed part, a movable part for holding an optical element, a driving assembly, and a positioning structure. The movable part is connected to the fixed part. The driving assembly is configured to drive the movable part to move relative to the fixed part. The positioning structure is formed on the movable part or the fixed part for positioning the optical element or at least one part of the driving assembly.
Claims19
A driving mechanism for driving an optical element to move, comprising:
- a fixed part;
- a movable part, connected to the fixed part for holding the optical element;
- a driving assembly, configured to drive the movable part to move relative to the fixed part;
- a cover;
- and
- a positioning structure, formed on the movable part and protrudes from a side of the movable part to restrict the cover.
A driving mechanism for driving an optical element to move, comprising:
- a fixed part;
- a movable part, connected to the fixed part for holding the optical element;
- a driving assembly, configured to drive the movable part to move relative to the fixed part, wherein the driving assembly has a magnet disposed on the fixed part and a coil disposed on the movable part;
- a cover;
- and
- a positioning structure, formed on the cover and having a protrusion, wherein the protrusion abuts and restrict the magnet in a vertical direction.
A driving mechanism for driving an optical element to move, comprising:
- a fixed part;
- a movable part, connected to the fixed part for holding the optical element;
- a driving assembly, having a plurality of magnets, a coil, and a circuit, wherein the magnets are disposed on the fixed part, and the coil and the circuit are integrally formed on opposite sides of the spring sheet for driving the movable part to rotate relative to the fixed part;
- and
- a positioning structure, formed on the movable part or the fixed part for positioning the optical element or at least one part of the driving assembly.
