VOICE COIL MOTOR FOR DRIVING LIQUID LENS AND LENS SET THEREOF

WIPO Patent Application WO/2019/178917

A1

The present invention relates to a lens driving device, and in particular, to a voice coil motor for driving a liquid lens and a lens set thereof. The voice coil motor for driving the liquid lens comprises a seat body, a carrier, and a driving device; the seat body is provided with a first accommodating cavity and a second accommodating cavity which are distributed along an optical axis and are used for fixing a first lens and the liquid lens respectively; the carrier is provided in the first accommodating cavity, a transmission component is fixedly provided on the carrier, and an extrusion part of the transmission component is fixed to a side surface of the liquid lens close to the first lens; the driving device is provided in the first accommodating cavity, and comprises a rotor and a stator which is in magnetic induction with the rotor and drives the rotor to move up and down along the optical axis; the stator is fixedly provided on the seat body; the rotor is fixed to the carrier; the transmission component is fixed on the carrier and moves up and down along the optical axis with the carrier for adjusting the curvature of the liquid lens. The technical problem to be solved by the present invention is to drive the liquid lens to realize optical anti-shake and auto focus functions.
