Title:
LENS DRIVING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/099848
Kind Code:
A1
Abstract:
A lens driving apparatus (100), comprising a first supporting frame (1), a second supporting frame (2), a lens barrel (3), a support assembly (4), anti-shake magnetic steels (5), anti-shake coils (6), a flexible circuit board (7) and metal sheets (8). The support assembly (4) forms a rotational connection relative to the first supporting frame (1), and the first supporting frame is suspended in the second supporting frame (2) such that the first supporting frame (1) forms a rotational connection relative to the second supporting frame (2). The anti-shake coils (6) drive the anti-shake magnetic steels (5) to deflect in a first direction or a second direction perpendicular to the optical axis direction. The metal sheets (8) are opposite to and spaced apart from the anti-shake magnetic steels (5) and form a mutual magnetic attraction with the anti-shake magnetic steels (5).
