Abstract
A lens module includes: a carrier having an internal space; a lens unit including a plurality of lens groups, the lens unit being installed on the carrier such that at least one of the lens groups is configured to move in a length direction of the carrier; a lens guide assembly including a plurality of guide members disposed on side surfaces of each of the lens groups, and configured to guide movement of at least two lens groups among the plurality of lens groups; and at least two driving wires connected to the plurality of guide members and formed of a shape memory alloy.
Claims15
A lens module, comprising:
- a carrier having an internal space;
- a lens unit comprising a plurality of lens groups, the lens unit being installed on the carrier such that at least one of the lens groups is configured to move in a length direction of the carrier;
- a lens guide assembly comprising a first guide member disposed on first side surfaces of each of the lens groups, a second guide member disposed to overlap the first guide member in a direction traverse to the length direction of the carrier, a third guide member disposed on second side surfaces of each of the lens groups, and a fourth guide member disposed to overlap the third guide member in the direction traverse to the length direction of the carrier, the first, second, third, and fourth guide members being configured to guide movement of at least two lens groups among the plurality of lens groups;
- and
- at least two driving wires connected to the guide members and formed of a shape memory alloy.
A camera module, comprising:
- a reflective module configured to change light incident to the camera module;
- and
- a lens module configured to pass light having a path changed by the reflective module, wherein the lens module comprises:
- a carrier having an internal space;
- a lens unit comprising a plurality of lens groups, the lens unit being installed on the carrier such that at least one of the lens groups is configured to move in a length direction of the carrier;
- a lens guide assembly comprising a plurality of guide members disposed on side surfaces of each of the lens groups, and configured to guide movement of at least two lens groups among the plurality of lens groups;
- at least two driving wires connected to the plurality of guide members and formed of a shape memory alloy;
- and
- a plurality of lifting support gears engaged with thread portions of the plurality of guide members.
