Abstract
A camera module according to an aspect of the invention may include: a housing; a fixed unit fixed to the inside of the housing; a lens barrel provided in the housing and having at least one lens; and a moving unit moved and supported by the fixed unit by a predetermined magnetic force, and moving the lens barrel along an optical axis, such that driving accuracy and reliability can be increased when performing auto focus or zoom.
Claims10
A camera module comprising:
- a housing;
- a fixed unit fixed to an inside of the housing,
- the fixed unit comprising a fixed support member fixed to the inside of the housing, a coil member provided at one side of the fixed support member, and a magnetic member provided at the other side of the fixed support member;
- a lens barrel provided in the housing and having at least one lens;
- and
- a moving unit moved and supported by the fixed unit by a predetermined magnetic force, and moving the lens barrel along an optical axis,
- the moving unit comprising a moving support member slidable relative to the fixed support member, and a magnet member supported closely by the moving support member and exerting a magnetic force on the magnetic member, and moving the moving support member by electromagnetic interaction with the coil member.
