Suspension assembly of optical image stabilizer

Abstract

The invention relates to the technical field of camera shake correction, and discloses a suspension assembly of an optical image stabilizer. The assembly comprises a printed circuit board and an elastic sheet movably arranged on the printed circuit board. The printed circuit board is electrically connected with the elastic sheet; the printed circuit board comprises a substrate and a bending part which extends downwards along the edge of any side of the substrate. A supporting frame is attached to the bottom face of the base plate, a plurality of conductive ends are arranged on the outer side face of the bent part, a plurality of reinforcing bodies corresponding to the conductive ends in a one-to-one mode are arranged on the inner side face of the bent part, and the reinforcing bodies are arranged at intervals and do not make contact with one another. The invention has the beneficial effects that the supporting frame and the reinforcing body are respectively arranged on the printed circuit board, so the strength of the printed circuit board can be ensured, the conductive ends can be effectively prevented from being electrically conducted when the printed circuit board is welded withother parts of the optical image stabilizer, and a short circuit phenomenon is prevented.

Description

technical field [0001] The invention relates to the technical field of camera shake correction, in particular to a suspension component of an optical image stabilizer. Background technique [0002] Optical Image Stabilizer (OIS) is mainly used in camera devices. Its working principle is: during the shooting process, the gyroscope detects small movements, and then transmits the signal to the processor, and the processor immediately calculates The amount of displacement that needs to be compensated, and then the displacement compensation is performed on the lens assembly to offset the external shake, so as to effectively overcome the image blur caused by the shake of the camera device. [0003] The suspension component is the most important structure of the optical image stabilizer. Its function is to drive the lens component to move according to the calculation of the processor, and then realize the displacement compensation of the lens. The suspension assembly is generally ...

AI Technical Summary

Problems solved by technology

The suspension assembly is generally composed of a printed circuit board 10 and elastic pieces that are movably arranged on the printed circuit board 10. Due to the soft nature of the printed circuit board 10, a support frame 13 needs to be provided on the back of the printed circuit board 10, and the support frame 13 extends from the base plate of the printed circuit board 10 to the inner surface of its bent part, please refer to the attached figure 1 As shown; since the support frame 13 is generally a conductive material such as metal, in the process of welding the bent portion of the printed circuit board 10 to other components, the conductive end on the printed circuit board 10 may be connected to the support due to the welding melting zone. The frame is electrically conducted, so that it is easy to electrically conduct each conductive end on the printed circuit board 10 through the supporting frame 13, causing a short circuit phenomenon in the printed circuit board 10
