Abstract
A damping mechanism includes a chamber, a movable blocking member and a power assembly. At least part of the movable blocking member is located in the chamber and cooperates with an inner wall face of the chamber to encloses a damping fluid cavity; at least one of the chamber and the movable blocking member defines a damping fluid circulation port in communication with the damping fluid cavity; and the power assembly is abutted against the movable blocking member, and configured to drive the movable blocking member to move relative to the chamber to change volume of the damping fluid cavity.
