Reflecting module for OIS and camera module including the same
There are provided a reflecting module for optical image stabilization (OIS) and a camera module including the same. The reflecting module for OIS includes a housing to which a board is coupled and including a through-hole, a moving holder connected to the housing by an elastic member, a reflecting member provided on the moving holder, and a driving part providing driving force to the moving holder to move the moving holder relatively with respect to the housing, wherein the elastic member includes a housing fixing part fixed to the housing and a holder fixing part fixed to the moving holder, wherein the driving part includes a magnet provided on the moving holder and a coil provided on the board and opposing the magnet, and wherein the coil is disposed to oppose the magnet through the through-hole.
1. A reflecting module for optical image stabilization (OIS), comprising:
a housing to which a board is coupled and including a through-hole;
a moving holder connected to the housing by an elastic member;
a reflecting member provided on the moving holder; and
a driving part providing driving force to the moving holder to move the moving holder relatively with respect to the housing,
wherein the elastic member includes a housing fixing part fixed to the housing housing, a holder fixing part fixed to the moving holder, and a moving spring connecting the housing fixing part and the holder fixing part to each other,
wherein the driving part includes a magnet provided on the moving holder and a coil provided on the board and opposing the magnet,
wherein the coil is disposed to oppose the magnet through the through-hole,
wherein the moving spring connects the surfaces of the housing fixing part and the holder fixing part facing each other,
wherein the moving spring includes a first spring including a plurality of springs extending in a first direction and a second spring including a plurality of springs extending in a second direction,
wherein the first direction and the second direction intersect each other, and
wherein a connection portion between the first spring and the second spring has a bent shape.
2. The reflecting module of claim 1 , wherein the board is coupled to an external surface of the housing to expose the coil to an interior of the housing through the through-hole.
3. The reflecting module of claim 1 , further comprising a position sensor provided on the board to oppose the magnet to sense a position of the moving holder.
4. The reflecting module of claim 3 , wherein the position sensor is a hall sensor.
5. The reflecting module of claim 1 , wherein the reflecting member is a prism.
6. The reflecting module of claim 1 , further comprising a reinforcing plate attached to the board.
7. The reflecting module of claim 1 , wherein the moving holder is provided in the housing to be suspended by the elastic member.
8. The reflecting module of claim 1 , wherein the elastic member is provided to extend to both lateral surfaces of the moving holder.
9. The reflecting module of claim 1 , wherein a moving spring moving the moving holder in the elastic member extends in a direction substantially parallel to a reflection surface of the reflecting member.
10. The reflecting module of claim 1 , further comprising an opening through which the reflecting member is exposed and a cover covering the moving holder.
11. The reflecting module of claim 1 , wherein the first spring and the second spring extend in a direction perpendicular to each other.
12. A camera module, comprising:
a lens module including a plurality of lenses; and
the reflecting module for OIS of claim 1 , disposed in front of the lens module and altering a path of light incident thereinto so that the light is directed toward the lens module.
