Document Type and Number:
WIPO Patent Application WO/2024/016448
Kind Code:
A1
Abstract:
The present invention provides a lens driving device, comprising: a base, a supporting frame, a lens barrel support, and an elastic assembly. The elastic assembly comprises a first fixing arm, a second fixing arm, and a plurality of elastic arms connected to the first fixing arm and the second fixing arm. Each elastic arm comprises a first elastic bending portion and a plurality of second elastic bending portions. The radius of curvature of the first elastic bending portion is greater than that of the second elastic bending portions. The lens driving device further comprises a plurality of damping adhesives, and each damping adhesive is arranged between the first elastic bending portion and the supporting frame. The surface of the supporting frame corresponding to the first elastic bending portion in an optical axis direction protrudes towards the first elastic bending portion to form fixing structures for fixing the damping adhesives, the first elastic bending portion is fixedly connected to the fixing structures by means of the damping adhesives. The damping adhesives at least partially wrap the first elastic bending portion. Compared with the prior art, the lens driving device of the present invention is good in anti-shake effect and low in production cost.
