Description

Optical anti-shake anti-collision structure and OIS motor Technical Field The utility model relates to the technical field of cameras, in particular to an optical anti-shake anti-collision structure. Background In recent years, optical anti-shake (OIS) technology has become a core support for smart phones, unmanned aerial vehicles, and portable imaging devices to achieve high quality imaging. As consumer demands for imaging definition, night scene capture, and dynamic video stability escalate, miniaturization, high frequency response, and impact resistance of OIS motors face greater challenges. Especially in the environments of equipment falling, rapid zooming or extreme temperatures, the structural reliability defect of the traditional OIS motor is increasingly remarkable, wherein the problem of foreign matter collision becomes an industry pain point which restricts the product yield and the user experience. Currently, the mainstream OIS motor mostly adopts a cantilever support structure, and displacement compensation of the lens group is realized through electromagnetic driving of a coil and a magnet. In order to limit the displacement over travel of the lens set, a plastic impact boss is usually arranged between the substrate and the movable frame. However, in the conventional design, the boss and the substrate are integrally formed by injection molding, and hard engineering plastics (such as PBT or LCP) are generally selected as materials. When the rigid connection is subjected to high-frequency impact, a buffer mechanism is lack between the boss and the movable frame, so that stress is concentrated at a contact point, and the boss is easy to wear and release scraps in collision, so that camera shooting is seriously affected.
