1. An optical image stabilization camera module, comprising:
a lens;
a photosensitive assembly having a photosensitive chip;
a first driving part adapted to mount the lens and drive the lens to translate in the directions of an x-axis and a y-axis; and
a second driving part comprising a second basic portion and a second movable portion, wherein the second basic portion and the second movable portion are movably connected by means of an elastic connecting portion, and the second driving part has four side surfaces; each side surface is provided with two interlaced shape memory alloy (SMA) wires, and two ends of each SMA wire are connected to a fixed end of the second basic portion and a fixed end of the second movable portion, respectively; and
each of the fixed ends is located in a corner area of the second basic portion or the second movable portion;
wherein the photosensitive assembly is fixed on the second movable portion, and the second movable portion is adapted to drive, under the drive of the SMA wires, the photosensitive chip to move in an xoy plane; and
wherein the lens and the photosensitive chip are configured to be simultaneously driven and move in opposite directions; and
wherein the x-axis and the y-axis are coordinate axes perpendicular to an optical axis of the camera module, the x-axis and the y-axis are perpendicular to each other, and the xoy plane is a plane formed by the x-axis and the y-axis.
