Problems solved by technology

This design scheme has very high requirements on the parts of the voice coil motor and the assembly accuracy between the parts, and because the pins are easy to break, the reliability of the OIS performance of the voice coil motor cannot be guaranteed, which leads to the poor quality of OIS motor products. The production rate is low, and the output is far from meeting the market demand

Abstract

The present invention discloses an OIS voice coil motor in which a carrier and a magnet holder are provided between the upper and lower elastic sheets. The magnet holder is positioned on the outer periphery of the carrier. The outer periphery of the carrier is wound with an AF coil and its upper and lower ends are respectively connected with the inner rings of the upper and lower elastic sheets. The magnet holder is internally provided with a magnet group, and the upper and lower ends of the magnet holder are connected with middle rings of the upper and lower elastic sheets respectively. The base is provided with an OIS coil group corresponding to the magnet group, and the OIS coil group is internally provided with a Hall element group. The elastic sheets of the OIS voice coil motor adopt the integrated structure, and the functions of moving in directions parallel to and vertical to the optical axis of the carrier is controlled to be integrated on the elastic sheets, so that the structure and the fittings of the OIS voice coil motor are simplified, the requirement for assembling technologies is lowered, the assembly of the OIS voice coil motor is facilitated, the cost is reduced, and the production yield rate is improved.

Description

technical field [0001] The invention relates to the field of voice coil motor anti-vibration, in particular to an OIS voice coil motor. Background technique [0002] The traditional OIS voice coil motor uses shrapnel to control the movement of the carrier in the direction parallel to the optical axis, and uses the spring to control the movement of the carrier in the direction perpendicular to the optical axis. This design scheme has very high requirements on the parts of the voice coil motor and the assembly accuracy between the parts, and because the pins are easy to break, the reliability of the OIS performance of the voice coil motor cannot be guaranteed, which leads to the poor quality of OIS motor products. The production rate is low, and the output is far from meeting the market demand. [0003] The shrapnel used for voice coil motors is generally designed with a two-stage structure, which only controls the movement of the carrier in the direction parallel to the opti...
