Anti-shake system for micro camera

Abstract

The present invention provides a kind of anti-shock system for micro-camera, which is mainly provided with a flexible circuit board on the four sides and the top inside, including two pairs (four) of anti-shock coils and a focus coil; A bracket with three corner seats is attached to the inner edge of the flexible circuit board; four anti-vibration coils are arranged between the four corner seats of the bracket, and the two pairs are arranged in series to form the static part of the anti-shock system; A camera objective lens seat is provided with a magnetically conductive yoke iron, and four magnets are respectively arranged on the periphery of the objective lens seat, and are arranged at intervals with the aforementioned four anti-vibration coils to form the mover part of the anti-shock system; An upper shrapnel and a lower shrapnel are respectively connected with the above-mentioned stator part and mover part to form an anti-shock system capable of moving independently in the X-Y-Z axis.

Description

Anti-shake system for miniature cameras technical field The present invention relates to a kind of anti-handshake system of miniature camera, especially about a kind of three-dimensional three-axis magnetic circuit that can be done The system's anti-shake focusing motor device can be widely used in mini photography equipment or matching with mobile phone camera systems. It has the advantages of saving parts and assembly costs, and not occupying a volume. Background technique

[0002] The technology of the motor of the miniature camera module is also more important as the photographic device tends to be lighter, thinner and shorter. Especially when the mobile phone has become an indispensable item in life, the need for the micro motor matched with the mobile phone is even more fulfilled. The peak, so the requirements for the anti-shake technology of micro motors are constantly increasing.

[0003] For the optical anti-shake (Optical Image Stabilization, hereinafter refe...
