VCM OIS actuator module

摘要

A lens actuator module including an autofocus (AF) mechanism capable of moving a lens according to at least three degrees of freedom and an optical image stabilization (OIS) mechanism capable of moving the lens according to at least two degrees of freedom. The AF mechanism may have a coil and a magnet assembly for driving movement of the lens according to the at least three degrees of freedom. The optical image stabilization (OIS) mechanism may include a coil and a magnet assembly for driving movement of the lens according to the at least two degrees of freedom.

1. A lens actuator module comprising:
an autofocus (AF) mechanism operable to move a lens according to at least three degrees of freedom during an AF operation, the AF mechanism having a coil and a magnet assembly for driving movement of the lens according to the at least three degrees of freedom; an optical image stabilization (OIS) mechanism operable to move the lens according to at least two degrees of freedom during an OIS operation, the at least two degrees of freedom different from the at least three degrees of freedom, the OIS mechanism having a coil and a magnet assembly for driving movement of the lens according to the at least two degrees of freedom; and a flexure assembly positioned between the AF mechanism and the OIS mechanism, the flexure assembly having a set of AF springs attached to the AF mechanism to allow for movement of the AF mechanism and a set of OIS springs attached to the OIS mechanism to allow for movement of the OIS mechanism.
