Abstract

A camera module comprising: a housing; a lens assembly that is fixed to the housing and comprises at least one lens; a circuit board that is arranged inside the housing and comprises a first circuit board and a second circuit board, on which image sensors arranged to face the lens are mounted, respectively; and a first shield can arranged inside the housing so as to support edges of the first and second circuit boards.

Claims

1. A camera module comprising:

a housing;

a lens assembly that is fixed to the housing and comprises at least one lens;

a circuit board that is arranged inside the housing and comprises a first circuit board and a second circuit board, on which image sensors arranged to face the lens are mounted, respectively; and

a first shield can arranged inside the housing so as to support edges of the first and second circuit boards,

wherein the first shield can includes at least one circuit board support part protruded toward an inside of the first shield can in order to support the edges of the circuit board, and a circuit board disengagement prevention part protruded toward an inside of the first shield can in order to inhibit the circuit board supported to the circuit board support part from being disengaged from the first shield can, and

wherein the circuit board disengagement prevention part is formed by a portion of a sidewall of the first shield can being pushed inward toward the inside of the first shield can, such that a hole is present in the sidewall of the first shield where the portion of the sidewall was pushed inward, the hole being between the circuit board disengagement prevention part and an exterior of the first shield can, in a direction perpendicular to an upper surface of the first circuit board.

2. The camera module of claim 1, wherein the first circuit board is mounted with the image sensor, and the first and second circuit boards are electrically connected by a first flexible circuit board.

4. The camera module of claim 1,

wherein the circuit board support part includes a first circuit board support part protruding inward from an inner surface of the first shield can to support a rim of the first circuit board and a second circuit board support part protruding inward from an inner surface of the first shield can to support an upper surface of the second circuit board.

5. The camera module of claim 1, wherein the first shield can is manufactured with a metal material, and edges of the circuit board are formed with a ground part electrically grounded to the first shield can.

6. The camera module of claim 1, comprising:

a second shield can coupled to the first shield can; and

a third circuit board fixed to the second shield can by being electrically connected to at least one of the first circuit board and the second circuit board using a second flexible circuit board.

7. The camera module of claim 6, wherein the second shield can is coupled with a first coupling part, and the second shield can is coupled with a second coupling part coupled with the first coupling part.

8. The camera module of claim 6, wherein the third circuit board is formed with a connector.

9. The camera module of claim 6, wherein the second shield can includes a third circuit board support part protruded toward an inside of the second shield can in order to support the third circuit board, and a second circuit board disengagement prevention part protruded toward an inside of the second shield can in order to inhibit the third circuit board from being disengaged.

10. The camera module of claim 1, wherein an area of the first shield can where the first flexible circuit board is disposed is formed in a bar shape partially cut away.

11. The camera module of claim 1, wherein a first ground part is formed on a side surface of the first circuit board, and the first ground part is in contact with an inner surface of the first shield can.

12. The camera module of claim 1, wherein a second ground part is formed on a side surface of the second circuit board, and the second ground part is in contact with an inner surface of the first shield can.

13. The camera module of claim 1, wherein the first circuit board and the second circuit board are formed in the same size.

14. The camera module of claim 6, wherein an area of the second shield can where the second flexible circuit board is disposed is formed in a bar shape partially cut away.

15. The camera module of claim 14, wherein a third ground part is formed on a side surface of the third circuit board, and the third ground part is in contact with an inner surface of the second shield can.

16. The camera module of claim 7, wherein the first coupling part includes a hole therethrough, and the second coupling part includes a projection that fits in the hole.

17. The camera module of claim 9, wherein the third circuit board support part protrudes inward from an inner surface of the second shield can to support an upper surface of the third circuit board.

18. The camera module of claim 17, wherein a plurality of third circuit board support parts are provided on mutually facing portions of the inner surface of the second shield can.

19. The camera module of claim 9, wherein the second circuit board disengagement prevention part protrudes inward from an inner surface of the second shield can to support a lower surface of the third circuit board.

3. A camera module comprising:

a housing;

a lens assembly that is fixed to the housing and comprises at least one lens;

a circuit board that is arranged inside the housing and comprises a first circuit board and a second circuit board, on which image sensors arranged to face the lens are mounted, respectively; and

a first shield can arranged inside the housing so as to support edges of the first and second circuit boards,

wherein the first shield can includes at least one circuit board support part protruded toward an inside of the first shield can in order to support the edges of the circuit board, and a circuit board disengagement prevention part protruded toward an inside of the first shield can in order to inhibit the circuit board supported to the circuit board support part from being disengaged from the first shield can, and

wherein the housing includes a front housing including a floor plate formed with a through hole exposing the lens and a circuit board fixing part fixing the first circuit board by being protruded from a surrounding of the through hole in the floor plate, and a rear housing coupled to the floor plate by accommodating the first shield can.

20. A camera module comprising:

a housing;

a lens assembly that is fixed to the housing and comprises at least one lens;

a first circuit board disposed inside the housing and mounted with an image sensor disposed to face the lens;

a second circuit board disposed below the first circuit board;

a third circuit board disposed below the second circuit board;
