LENS DRIVING APPARATUS, CAMERA MODULE, AND CAMERA HOLDING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/206053
Kind Code:
A1
Abstract:
A lens driving apparatus (1), a camera module (A), and a camera holding apparatus (M) are provided. A shake correction support section (30) of the lens driving apparatus (1) is made of an elastic material, and has a biaxial hinge structure that movably supports, in a plane orthogonal to an optical axis, a shake correction movable section (10). An auto focus support section (13) has a support body (41) and a reinforcing section (42). The support body (41) has a fixed end (411) connected to an auto focus fixing section (12), free ends (413) connected to an auto focus movable section (11), and arms (412) connected to the fixed end (411) and the free ends (413). The arms (412) are made of an elastic material, with two hinge sections (412a, 412b) thinner than surrounding structures and axes orthogonal to the optical axis, that move together with the auto focus movable section (11) towards the optical axis. The arms (412) bend in opposite directions at the two hinge sections (412a, 412b). The reinforcing sections (42) are made of a material more rigid than the elastic material of the arms, and are disposed between the two hinge sections (412a, 412b) of the arms (412).
