OG exemplary drawing
 
1. A driving mechanism for an optical element, comprising:
a support body;
a movable portion, located in the support body, movable relative to the support body, and configured to connect to an optical element;
an elastic assembly, movably connected to the support body and the movable portion; and
a driving assembly, disposed on the support body and the movable portion, and configured to drive the movable portion to move relative to the support body;
wherein the support body comprises a base and a casing which form a receiving space, wherein the movable portion, the elastic assembly, and the driving assembly are disposed in the receiving space, and the elastic assembly suspends the movable portion in the receiving space;
wherein the elastic assembly has a sheet structure, and an extending direction of the elastic assembly is toward the base;
wherein the elastic assembly movably connects the casing and the movable portion;
wherein the casing comprises an upper shell and a sidewall, wherein the upper shell is parallel to the base, and the upper shell is perpendicular to the sidewall;
wherein the movable portion comprises a connecting element configured to connect the optical element, wherein the connecting element extends toward the sidewall of the casing;
wherein the casing further comprises an opening on the sidewall of the casing, wherein the connecting element passes through the opening.
