Title:
LENS FIXING STRUCTURE FOR OPTICAL ACTUATOR AND CORRESPONDING CAMERA MODULE
Document Type and Number:
WIPO Patent Application WO/2022/068421
Kind Code:
A1
Abstract:
A lens fixing structure for an optical actuator, comprising: a carrier (52), which is suitable for performing controlled movement under the drive of the optical actuator; a lens barrel (51) the inner side of which is suitable for mounting lenses; and an elastic member (53), which comprises a fixing part (531) for connecting the lens barrel (51) and a connecting part (532) for connecting the carrier (52), wherein the fixing part (531) comprises two arc-shaped side walls (534), and the two arc-shaped side walls (534) bear against the outer side surfaces at two sides of the lens barrel (51) respectively, or are respectively embedded in the lens barrel (51). The present application also relates to a camera module that comprises the lens fixing structure. The elastic member (53) is arranged between the lens barrel (51) and the carrier (52), so that while the lens barrel (51) is fixed, stress uniformity can be achieved at two sides, thus avoiding problems caused by uneven stress caused by glue bonding, and helping to increase production efficiency and yield.
