Problems solved by technology

Since the suspension wire is the unreturned part of the carrier, problems such as deformation when impacted will affect the circuit transmission and even lead to overall failure
In addition, the suspension wire is involved in the circuit transmission, and it is relatively difficult to assemble components such as the upper reed

Abstract

The invention discloses a periscope lens drive device. The device comprises a base, a carrier, a bottom circuit board, an OIS component and an AF component, wherein the OIS component comprises an OISmagnet and an OIS coil group, the AF component comprises an AF magnet and an AF coil group, the carrier is provided with a lens installation hole for installing a lens, the OIS magnet is installed attwo sides of the lens installation hole of the carrier, the AF magnet is installed at the bottom of the carrier, the AF coil group is installed on the bottom circuit board and is matched with the AF magnet, two ends of the base are provided with a convex block protruding upward integrally, the OIS coil group is installed on the convex block and is matched with the OIS magnet, the base is internally provided with an embedded metal sheet, and the OIS coil group is electrically communicated with the embedded metal sheet and drives the carrier to move when being powered so as to realize the optical image stabilization function. In the periscope lens drive device, a suspension wire is not involved in an integral circuit and is involved in physical motions like homing, thereby guaranteeing circuit stable.

Description

technical field [0001] The invention relates to the technical field of optical imaging equipment, in particular to a periscope lens driving device. Background technique [0002] With the development of technology, many electronic devices (such as smart phones or digital cameras) now have the function of taking photos or recording videos. The use of these electronic devices is becoming more and more common, and they are developing towards the direction of convenience and thinner design, so as to provide users with more choices. [0003] Some electronic devices with camera or video functions are equipped with a lens driving module to drive an optical component such as a lens to move, thereby achieving autofocus and optical image stabilization (OIS) functions. The light can pass through the aforementioned optical component and form an image on a photosensitive component. [0004] However, these lens driving modules generally have a suspension wire structure, and the suspensio...
