Camera module
There is provided a camera module including: a lens barrel including at least one lens disposed on an optical axis; a housing having the lens barrel disposed therein; and first and second elastic members elastically supporting upper and lower portions of the lens barrel, respectively, wherein the first and second elastic members include a fixed side coupled to the housing and a driving side coupled to the lens barrel, respectively, the fixed side and the driving side being disposed to face each other based on the optical axis.
1. A camera module comprising:
a lens barrel including at least one lens disposed on an optical axis;
a housing having the lens barrel disposed therein; and
first and second elastic members elastically supporting upper and lower portions of the lens barrel, respectively,
wherein the first and second elastic members include a fixed side coupled to the housing and a driving side coupled to the lens barrel, respectively, the fixed side and the driving side being disposed to face each other based on the optical axis,
wherein the first and second elastic members further include a connecting side connecting the fixed side and the driving side to each other, respectively,
wherein the connecting side has a connecting portion and a bent portion extended from the connecting portion, and
wherein the bent portion is extended from one end of the connecting portion and is connected to the fixed side, and the other end of the connecting portion is connected to the driving side.
2. The camera module of claim 1 , wherein the lens barrel has a magnet mounted thereon so that one surface of the magnet is exposed to the outside, and the lens barrel and the magnet have a first yoke disposed therebetween so as to enclose surfaces of the magnet other than one surface of the magnet.
3. The camera module of claim 2 , wherein the housing has a coil and a second yoke attached thereto, the coil being disposed to face the magnet and the second yoke enclosing the coil.
4. The camera module of claim 2 , wherein the driving side is positioned to be close to the magnet based on the optical axis, and the fixed side is positioned to be opposite to the driving side based on the optical axis.
5. The camera module of claim 1 , wherein initial positions of the fixed side and the driving side are different from each other in an optical axis direction.
6. The camera module of claim 1 , wherein an initial position of the fixed side is behind that of the driving side in an optical axis direction.
7. A camera module comprising:
a lens barrel including at least one lens disposed on an optical axis;
a housing having the lens barrel disposed therein; and
first and second elastic members elastically supporting upper and lower portions of the lens barrel, respectively,
wherein the first and second elastic members include a fixed side coupled to the housing and a driving side coupled to the lens barrel, respectively, the fixed side and the driving side being disposed to face each other based on the optical axis,
wherein the first and second elastic members further include a connecting side connecting the fixed side and the driving side to each other, respectively,
wherein the connecting side has a connecting portion and a bent portion extended from the connecting portion, and
wherein the bent portion is branched and extended from one end of the connecting portion into two portions, and the branched portions are connected to the fixed side, respectively.
8. The camera module of claim 7 , wherein a single closed curve is formed by the bent portion and the fixed side.
9. The camera module of claim 1 , wherein the bent portion is extended from at least one of one end and the other end of the connecting portion.
10. The camera module of claim 1 , wherein a width of the bent portion is smaller than that of the connecting portion.
11. A camera module comprising:
a lens barrel including at least one lens disposed on an optical axis;
a housing having the lens barrel disposed therein;
a driving part comprising a magnet provided to one side of the lens barrel and a coil provided to the housing so as to face the magnet, and
an elastic member elastically supporting the lens barrel,
wherein the elastic member includes a driving side coupled to the lens barrel, a fixed side coupled to the housing and a connecting side connecting the fixed side and the driving side to each other, and wherein a single closed curve is formed by the connecting side and the fixed side.
12. The camera module of claim 11 , wherein an initial position of the fixed side is behind that of the driving side in an optical axis direction.
13. The camera module of claim 11 , wherein a yoke is attached to the lens barrel and the yoke encloses the magnet so that one surface of the magnet is exposed to the outside.
