Exempt from that SMA wire is arranged in a crossed manner and in static state when avoids partial structure run-off the straight.
A kind of image stabilizer, it includes a fixed frame, a movable frame and a driving unit.The fixed frame has
There are a central shaft, opposite upper end and lower end and first projection from upper end extension.The movable frame elastic connection
In the upper end and coaxial with the fixed frame.The driving unit includes two first resistor clamping pieces and first SMA wire.Should
Two first resistor clamping pieces are individually fixed on adjacent two side of the movable frame.The both ends difference of first SMA wire
Be fixed on two first resistor clamping pieces, which includes bending part positioned at the both ends between, the bending part and
First projection supports.The first resistor clamping piece heats first SMA wire to change the length of first SMA wire to galvanization
Spend and drive the movable frame to be rotated around first projection.
A kind of image-taking device, it includes image stabilizer as described above and a camera module.The movable frame and should
Fixed frame is collectively forming a receiving space.The camera module is contained in the receiving space and with the fixed frame separately, should
Camera module is fixedly connected with the movable frame.
A kind of image-taking device, it includes image stabilizer as described above and a camera module.The camera module bag
Include a lens unit, a base and an image sensor being contained in the base.The movable frame and the fixed frame are total to
With one receiving space of formation.The direction entered along light, the lens unit and the base are contained in the receiving space successively.
The base is fixedly connected with the fixed frame, which is fixedly connected with the movable frame and between the base and the fixed frame
Every the optical axis of the lens unit is aligned with the center of the image sensor.
Compared to the prior art, the setting of the first SMA wire in the image stabilizer and image-taking device has no intersection, avoids
The generation of short circuit phenomenon；In addition, because movable frame is resiliently attached on the fixed frame, image stabilizer and capture dress are avoided
