Abstract: An optical driving mechanism is provided, including a fixed portion, a movable portion, a drive assembly, and a position sensing assembly. The movable portion is movably connected to the fixed portion and configured to carry a first optical element. The drive assembly is configured to drive the movable portion relative to the fixed portion to move within a limited range including a first range and a second range. The position sensing assembly is configured to sense the movement of the movable portion, and includes a reference element, a first position sensing element, and a second position sensing element. The first and second position sensing elements respectively correspond to the reference element in the first and second ranges, wherein a first position sensing surface of the first position sensing element and a second position sensing surface of the second position sensing element are arranged in a first direction.

Abstract: An optical member driving mechanism for driving an optical member having an optical axis is provided, including a fixed portion, a movable portion, a first elastic member, and a driving assembly. The movable portion is configured to hold the optical member, and is movably connected the fixed portion via the first elastic member. The driving assembly drives the movable portion to move along the optical axis within a range of motion. The range of motion includes a first limit moving range and a second limit moving range. The first limit moving range is the maximum distance that the movable portion can move toward the light-entering side, and the second limit moving range is the maximum distance that the movable portion can move toward the light-emitting side. When the movable portion is in a predetermined position, the first limit moving range is greater than the second limit moving range.
