CAMERA MODULE

Abstract

A camera module comprises a main body, a cone disposed in the main body to accommodate a lens, a base joined to the cone, a frame movably disposed on the base, an image detection unit fixed to the frame and moving on the base via the frame, a first circuit board joined to the image detection unit and moving on the base via the image detection unit, a second circuit board disposed on the main body, and a flexible circuit board with one end connected to the first circuit board and the other end connected to the second circuit board. The flexible circuit board has a plurality of slits dividing the flexible circuit board into a plurality of strips. The slits are parallel and extend from the first circuit board to the second circuit board.

Claims

1. A camera module, comprising: a main body;a cone disposed in the main body to accommodate a lens;a base joined to the cone;a frame movably disposed on the base;an image detection unit fixed to the frame and moving on the base via the frame;a first circuit board joined to the image detection unit and moving on the base via the image detection unit;a second circuit board disposed on the main body; anda flexible circuit board with one end connected to the first circuit board and the other end connected to the second circuit board, wherein the flexible circuit board has a plurality of slits dividing the flexible circuit board into a plurality of strips.

2. The camera module as claimed in claim 1, wherein the slits are parallel.

3. The camera module as claimed in claim 1, wherein the slits extend from the first circuit board to the second circuit board.

4. The camera module as claimed in claim 1, wherein the frame comprises: a first guide element by which the frame is joined to the base and moved along a first axis;at least one first coil disposed on the frame;at least one first magnet fixed to the base and opposite the first coil; anda first Hall element disposed on the frame adjacent to the first coil, wherein magnetic flux variation is generated between the first coil and the first magnet by providing voltage to the first coil, thereby moving the first guide element along the first axis.

5. The camera module as claimed in claim 4, wherein the frame further comprises: a moving frame joined to the base by the first guide element and moving along the first axis relative to the base, wherein the first coil and the first Hall element are disposed on the moving frame;a seat disposed on the moving frame capable of moving relative to the base.

6. The camera module as claimed in claim 5, wherein the seat comprises: a second guide element by which the seat is joined to the moving frame and moves along a second axis relative to the moving frame;at least one second coil disposed on the seat;at least one second magnet disposed on the base opposite the second coil; anda second Hall element disposed on the seat adjacent to the second coil, wherein magnet flux variation is generated between the second magnet and the second coil by providing voltage to the second coil to move the seat along the second axis via the second guide element.

7. The camera module as claimed in claim 6, wherein the second guide element comprises: a plurality of second holding portions disposed on the seat; anda pair of second guide bars held parallel by the second holding portions and fixed to the moving frame, whereby the moving frame is joined to the seat, and the seat moves along the axis of the second guide bar.

8. The camera module as claimed in claim 7, wherein the axis of the second guide bar is perpendicular to the axis of the first guide bar.

9. The camera module as claimed in claim 8, wherein the first magnet comprises an N pole and an S pole disposed in the axis of the first guide bar.

10. The camera module as claimed in claim 7, wherein the second magnet comprises an N pole and an S pole disposed in the axis of the second guide bar.

11. The camera module as claimed in claim 4, wherein the first guide element comprises: a plurality of first holding portions disposed on a pair of sidewalls of the moving frame; anda pair of first guide bars held parallel by the first holding portions and fixed to the base, whereby the moving frame is joined to the base, and the moving frame moves in the axis of the first guide bar.
