Anti-shake driving assembly and camera module
By employing piezoelectric actuators and a reasonable layout scheme in the camera module, the problems of insufficient driving force and low stability of existing driving components in high-pixel, large-chip camera modules have been solved, achieving higher precision and longer stroke optical performance adjustment, and meeting the requirements for lightweight and thin camera modules.

Abstract
Disclosed are an anti-shake driving assembly and a camera module, wherein the anti-shake driving assembly comprises an anti-shake fixed part with a receiving cavity and an anti-shake movable part suspended in the receiving cavity of the anti-shake fixed part, and the receiving cavity is divided into a first part and a second part by the anti-shake movable part. The anti-shake driving assembly further comprises an anti-shake driving part and a pre-pressure device arranged in the second part of the receiving cavity, and a guide device clamped in the first part of the receiving cavity, wherein the anti-shake driving part is frictionally coupled to the anti-shake movable part through the pre-pressure device, and the guide device is used for guiding the movement of the anti-shake movable part. In particular, when the anti-shake driving part is driven, the friction between the anti-shake driving part and the anti-shake movable part is greater than the friction encountered by the guide device in the first part.
