Abstract

The present invention relates to a lens driving device and more particularly relates to a voice coil motor for driving a liquid lens and a lens group thereof. The voice coil motor for driving the liquid lens comprises a seat body, a carrier and a driving device. The seat body has a first receiving cavity and a second receiving cavity which are distributed along an optical axis and are used for fixing a first lens and the liquid lens. The carrier is set in the first receiving cavity, the carrier is fixedly provided with a transmission component whose pressing portion is fixedly disposed on a side of the liquid lens adjacent to the first lens. The driving device is set in the first receiving cavity and comprises a mover and a stator which is magnetically induced with the mover and drives themover to move up and down along the optical axis, the stator is fixedly set on the seat body, the mover is fixedly disposed with the carrier, and the transmission component is fixed on the carrier tomove up and down along the optical axis with the carrier to adjust the curvature of the liquid lens. The technical problem to be solved by the present invention is to drive the liquid lens to realizeoptical vibration prevention and autofocus functions.

Description

technical field [0001] The invention relates to a lens driving device, in particular to a voice coil motor for driving a liquid lens and a lens group thereof. Background technique [0002] Auto Focus (Auto Focus) is to use the principle of object light reflection, the reflected light is received by the sensor CCD on the camera, and the method of driving the electric focusing device to focus through computer processing is called auto focus. [0003] Autofocus technology has been widely used in imaging fields such as cameras, video cameras, and image scanning. In the prior art, fixed-focus lenses generally use a motor as a power source to drive the fixed-focus lens to move to zoom and focus, and the positioning is accurate. [0004] In order to meet the needs of miniaturization of portable imaging devices, a liquid lens has been developed in recent years. The liquid lens mainly changes the curvature of the interface of the liquid body by applying a voltage to the chamber conta...
