Optical image stabilization device and optical device

An optical device, comprising an optical image stabilization device, wherein the optical image stabilization device is applicable to a lens having an optical axis and comprises:

• a housing having a mounting space;
• a focusing structure provided in the mounting space;
• an elastic connection structure connected between the focusing structure and the housing and configured to enable the focusing structure to have a movement trend toward a first side of the housing in a direction of the optical axis in a free state;
• image stabilization balls provided between the focusing structure and the first side of the housing, wherein the image stabilization balls are sandwiched between the focusing structure and the first side of the housing due to the movement trend, and the image stabilization balls are capable of rolling in a plane perpendicular to the optical axis under an external force;
• and
• a driving structure provided at the focusing structure and the housing and configured to generate a driving force between the focusing structure and the housing to drive the focusing structure to move and simultaneously make the image stabilization balls roll, in such a manner that the focusing structure moves in a direction perpendicular to the optical axis under a guidance of the image stabilization balls.
