1. An induction activated cover assembly, comprising:

  • a main body, having an opening vertically penetrating the main body, a rear chamber being defined by the main body, a lateral connecting groove being formed on a top surface of the main body, the rear chamber and the connecting groove being located behind the opening, two through holes being formed on two ends of the connecting groove respectively;

    a cover, pivotably disposed on the main body to move pivotably between an open position and a close position, the opening being open as the cover is at the open position, the opening being closed as the cover is at the close position, a lateral connecting body being formed on a rear end of the cover, the connecting body having a connecting body opening facing downward, two pivot bores being formed on two ends of the connecting body and corresponding to the through holes respectively;

    a covering plate, enclosing the connecting body opening, a receiving room being defined between the connecting body and the covering plate;

    two pivots, disposed in the receiving room, each pivot inserting through one of the pivot bores and its corresponding through hole to pivot the cover on the main body;

    an induction unit for detecting a movement of a target body;

    a driving unit, operatively connecting to the induction unit, the induction unit selectively activating the driving unit to drive the cover to pivotably move between the open position and the close position as the induction unit detects the target body moving;

    at least one resilient unit, being disposed in the rear chamber, the resilient unit providing the cover with a torque force for the cover to have a tendency to pivotably move to the open position.
