Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a circuit for optics anti-shake drive arrangement, including fixed plate 1, metal sheet 2, fly leaf 3, FPC4, cushion 5, elastic arm 6 and SMA line 7, the laminating of 1 top face of fixed plate is fixed with metal sheet 2, the parallel fly leaf 3 that is equipped with in metal sheet 2 top, and the laminating of 3 surfaces of fly leaf installs FPC4, the four corners position of fly leaf 3 all is equipped with elastic arm 6, and

cushion

5 and 1 fixed connection of fixed plate are passed through to 6 bottoms of elastic arm, 3 sides of fly leaf all are equipped with SMA line 7, and SMA line 7 both ends respectively with

metal sheet

2 and 3 fixed connection of fly leaf.

The FPC4 disposed on the movable plate 3 is used for wiring, and a sensor and/or a controller may be disposed on the FPC4, and when the autofocus module of the lens is mounted on the movable plate 3, the wiring of the autofocus module may be connected to the outside through the FPC 4.

The camera lens module is carried on the surfaces of the movable plate 3 and the FPC4, the movable plate 3 and the FPC4 are suspended and fixed on the surface of the fixed plate 1 through the fixed connection of the elastic arm 6, so that the lens module is suspended and mounted, the characteristics of thermal contraction of the SMA wire 7 are matched, the motion of the camera along an X axis and a Y axis is realized, the rigidity of the Z direction is very large, the Z direction displacement of the camera can be ignored, therefore, a supporting part can not be needed below the movable plate 3, the influence of friction force is avoided, the plane movement of the camera module is stable and quick, and the camera lens module has a stable anti-shaking effect.

The FPC4 layout bypasses the bending region on the surface of the metal plate 2, and the FPC4 layout does not overlap the bending region of the metal plate 2, so that the use of the metal plate 2 is prevented from being influenced.

The bending feature for limiting the FPC4 is arranged on the elastic arm 6 at one corner of the movable plate 3, and the FPC4 is attached to the bending part of the elastic arm 6, so that a limiting effect can be achieved on the FPC4, and the FPC4 is prevented from swinging.

The elastic arms 6 are formed by bending, the elastic arms 6 are formed by bending at one time, so that the fixed part and the movable part of the movable plate 3 can be ensured to be in the same plane and not influenced by the bending precision, the four elastic arms 6 can also be bent twice respectively, so that the fixed part and the movable part of the movable plate 3 can be out of the same height, and whether the fixed part and the movable part are in the same plane is not limited.
