Patent attributes
A lens assembly driving module includes a base, a cover, a lens carrier and a damping agent. The cover is coupled to the base. The lens carrier is integrally formed with a plastic barrel into a coaxial unitary element which has an internal space for receiving at least one optical lens element and includes at least two protrusion portions located on one end of the coaxial unitary element close to the base. The damping agent is filled between the base and each of the protrusion portions. The protrusion portions are a part of the coaxial unitary element, and a distance in a direction perpendicular to an optical axis between the part of the coaxial unitary element and the internal space is a maximum distance among distances in the direction perpendicular to the optical axis between other parts of the coaxial unitary element and the internal space.
