Problems solved by technology
In related technologies, spring suspension is usually used to support and reset the moving part, but the spring structure will shake the captured image or video due to its own elastic vibration during the movement process, which will affect the imaging quality of the optical imaging system
In addition, the structure with spring suspension has high energy consumption, and the system is prone to resonance when applying closed-loop control, which is difficult to control

The invention relates to an optical anti-vibration motor and a camera module. The motor comprises a fixed part and a moving part, wherein the fixed part comprises a base and a shell covering the base; the moving part is movably installed on the base, the shell covers the periphery of the moving part, one of the fixed part and the moving part is provided with a coil, and the other one of the fixed part and the moving part is provided with a magnet capable of generating electromagnetic induction with the coil so as to drive the moving part to move relative to the fixed part in the direction perpendicular to the optical axis of an optical device, a magnetic piece is arranged on the side, which is opposite to the magnet, of the coil, the magnetic piece is arranged in the mode that the magnetic attraction force generated by the magnetic piece and the magnet can drive the moving part to reset to the initial position when the moving part deviates relative to the fixed part, and the center axis of the magnetic piece is aligned with the center axis of the magnet in the initial position. The magnetic piece can generate magnetic attraction force to the magnet to guide the moving part. The motor can provide power-off restoring force, energy consumption is saved, abnormal sound is avoided, and the resetting process is stable, so that the reliability of the optical anti-vibration motor can be improved.
Description
technical field [0001] The present disclosure relates to the field of optical technology, and in particular, to an optical anti-shake motor and a camera module. Background technique [0002] An optical system is a system used for imaging or optical information processing, which can be applied in various fields, for example, it can be applied to the lens of mobile phone camera, camera or projection technology. With the development of technology, the photographic and video effects of electronic products are becoming clearer and clearer. For example, the introduction of an optical anti-shake motor in the camera module can solve the problem of unclear imaging caused by shaking during shooting. In related technologies, spring suspension is usually used to support and reset the moving part, but the spring structure will shake the captured image or video due to its own elastic vibration during the movement process, which will affect the imaging quality of the optical imaging syste...
