Abstract

The sensor anti-shake motor comprises an external supporting structure composed of an outer shell and a bottom plate, a focusing mechanism, a carrier, an anti-shake mechanism and a conductive mechanism are installed in the external supporting structure, and the focusing mechanism is connected with the carrier through a front suspension wire spring and a rear suspension wire spring. The anti-shake mechanism is connected with the carrier through the anti-shake suspension wire, and the conductive mechanism is electrically connected with the anti-shake mechanism, the front suspension wire spring, the rear suspension wire spring and the anti-shake mechanism. The anti-shake mechanism and the conductive mechanism are redesigned, so that the structure is more compact, the integration level and the overall degree are higher, the assembly process is simplified on the premise that the product size is reduced, and the assembly difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of OIS motors, in particular to the technical field of sensor shift OIS motors, and in particular to a sensor anti-shake motor. Background technique [0002] At present, the micro-camera used in smart phones is the main application field of high-end anti-shake camera technology. As far as the existing technology is concerned, as a typical solution for high-end technology in this field, the Sensor-Shift technology is used to replace the current ordinary OIS optical image stabilization is used to improve the effect of the camera capturing dynamics. Prior to this, the most widely used OIS optical image stabilization solutions on smartphone products were realized by VCM motor-driven lens for angle correction. However, such a solution has long had disadvantages such as high power consumption, limited anti-shake effect, large product size, and high unit price. As the scenes of mobile phone photography become more...
