Abstract
A lens moving apparatus includes a bobbin including a first coil disposed therearound, a first magnet disposed to face the first coil, a housing for supporting the first magnet, upper and lower elastic members each coupled to both the bobbin and the housing, a base disposed to be spaced apart from the housing by a predetermined distance, a second coil disposed to face the first magnet, a printed circuit board on which the second coil is mounted, a plurality of support members, which support the housing such that the housing is movable in second and/or third directions and which connect at least one of the upper and lower elastic members to the printed circuit board, and a conductive member for conductively connecting the upper and lower elastic members.
Claims20
A lens moving apparatus, comprising:
- a base;
- a housing disposed on the base;
- a bobbin disposed in the housing so as to move in a first direction along an optical axis;
- a first coil disposed on the bobbin;
- a first magnet disposed to be opposite to the first coil;
- a first sensor disposed on the housing and comprising a plurality of pins;
- an upper elastic member coupled to the housing and an upper surface of the bobbin and comprising a first upper elastic member, a second upper elastic member, a third upper elastic member, and a fourth upper elastic member, which are spaced apart from one another;
- a lower elastic member coupled to the housing and a lower surface of the bobbin;
- a printed circuit board disposed between the base and the housing and conductively connected to at least one of the upper and lower elastic members;
- a second coil disposed to face the first magnet;
- a support member comprising at least one wire that supports the housing such that the housing is movable with respect to the base in second and/or third directions perpendicular to the first direction and conductively connecting at least one of the upper and lower elastic member to the printed circuit board;
- a plurality of circuit patterns conductively connected to the plurality of pins of the first sensor;
- and
- a plurality of elastic member contacts including a first elastic member contact conductively connected to the first upper elastic member, a second elastic member contact conductively connected to the second upper elastic member, a third elastic member contact conductively connected to the third upper elastic member, and a fourth elastic member contact conductively connected to the four upper elastic member,
- wherein the first sensor is disposed lower than the plurality of elastic member contacts.
