Anti-shake miniature holder capable of driving camera module

Abstract

The invention belongs to the technical field of anti-shake holders, and particularly relates to an anti-shake miniature holder capable of driving a camera module. The anti-shake miniature holder comprises a positioning base, a camera module carrier, at least one set of magnets, a magnet carrier, at least one set of independent coils, at least one set of elastic assemblies and a circuit board. Theindependent coils are fixed to the positioning base and are also electrically connected with the circuit board. A fixed structure is formed by the positioning base, the independent coils and the circuit board. The camera module carrier is fixedly connected with the magnet carrier. The magnets are installed on the magnet carrier. A movable structure is formed by the camera module carrier, the magnet carrier and the magnets. The anti-shake miniature holder further comprises the at least one set of elastic assemblies, and an elastic assembly vibrator system with multi-axis rotation freedom degrees is formed by the fixed structure, the movable structure and the elastic assemblies. The anti-shake miniature holder solves the problem that in the prior art, because relative movement exists betweenoptical components and image sensors and exists between magnets in actuators and magnets in holders, the anti-shake effect is influenced and the power consumption is increased.

Description

technical field [0001] The invention belongs to the technical field of anti-shake pan-tilts, and in particular relates to an anti-shake miniature pan-tilt capable of driving a camera module. Background technique [0002] In recent years, mobile devices with fixed-focus and wide-angle (viewing angle exceeding 80 degrees) shooting functions have become very popular, and their application range has been expanding, including aerial photography, action cameras, and driving recorders. When taking photos and videos, it is likely to be blurred or shaken by external vibrations, which will affect the quality of photos and videos. This problem is exacerbated when the vibrations are intense, or in low light situations. [0003] In order to solve the above problems, many existing anti-shake technologies have appeared on the market. The prior art described in the mainstream reads vibration sensors (such as gyroscopes and acceleration sensors), calculates vibration waveforms and required...
