1. An optical anti-shake driving device, comprising:
a focusing motor assembly, configured to support an optical component;
a base, configured to support the focusing motor assembly;
an optical anti-shake frame, configured to connect the focusing motor assembly and the base; and
an optical anti-shake resilient support mechanism, configured to make the focusing motor assembly suspend on the base, resiliently support on the focusing motor assembly and the base, and resiliently support on the focusing motor assembly and the optical anti-shake frame; wherein the optical anti-shake resilient support mechanism comprises:
two X-direction resilient sheets, symmetrically distributed with an optical axis of the optical component as an axis of symmetry and configured to connect the focusing motor assembly and the optical anti-shake frame or to connect the base and the optical anti-shake frame; and
two Y-direction resilient sheets, symmetrically distributed with the optical axis of the optical component as an axis of symmetry and configured to connect the base and the optical anti-shake frame or to connect the focusing motor assembly and the optical anti-shake frame;
a driving assembly, comprising an X-axis driving assembly and a Y-axis driving assembly, wherein the X-axis driving assembly is configured to drive the focusing motor assembly to translate unidirectionally along an X-axis in a horizontal plane perpendicular to the optical axis; and the Y-axis driving assembly is configured to drive the focusing motor assembly to translate unidirectionally along a Y-axis in the horizontal plane perpendicular to the optical axis;
wherein the X-axis driving assembly comprises two X-axis driving coils fixed on the base, and two opposite sides at a lower end of an outer frame of the focusing motor assembly are respectively disposed with X-axis driving magnets corresponding to the two X-axis driving coils one by one;
wherein the Y-axis driving assembly comprises two Y-axis driving coils fixed on the base, and the other two opposite sides at the lower end of the outer frame of the focusing motor assembly are respectively disposed with Y-axis driving magnets corresponding to the two Y-axis driving coils one by one; and
wherein each of the X-axis driving magnets is one of a single magnet and a double magnet, and each of the Y-axis driving magnets is one of a single magnet and a double magnet.
