CAMERA ACTUATOR

摘要

An actuator package includes a base frame member and an image sensor. The actuator package further includes a plurality of comb drive actuators affixed to the base frame member by a plurality of respective electrically conductive leaf spring flexures. The respective electrically conductive leaf spring flexures provide an electrical current conductive path between the image sensor and conductors mounted on the base frame member, and the plurality of comb drive actuators is arranged to control the motion of the image sensor in multiple degrees of freedom relative to the fixed structure. Each of the plurality of comb drive actuators includes at least two independent comb drive array portions. At least one of the comb drive array portions generates force tending to move the image sensor out of a plane of the base frame member.

1. An actuator assembly for mounting a digital image sensor, comprising:
a base frame member; an image sensor; and a plurality of comb drive actuators affixed to the base frame member by a plurality of respective leaf spring flexures, wherein
the respective leaf spring flexures provide forces to move the image sensor relative to the base frame member along an optical axis of the image sensor, a first orthogonal axis orthogonal to the image sensor, and a second orthogonal axis orthogonal to both the first orthogonal axis and the optical axis, andthe respective leaf spring flexures provide forces to move the image sensor relative to the base frame member in roll directions relative to each of the optical axis, the first orthogonal axis, and the second orthogonal axis.
