Abstract:
1. An automatic winding device used for automatic winding watch, comprising a box body, a rotating seat arranged on the box body and relatively rotatable to the box body, a holding seat fixed on the rotating seat and used for placing the automatic winding watch, a driving mechanism driving the rotating seat to rotate, and a control device controlling a rotating mode of the driving mechanism, wherein the driving mechanism is arranged in the box body; the control device comprises a random number generation module for generating random parameters, a pulse duration modulation module matched with the random number generation module so as to generate the rotating mode, and a driving circuitry; wherein the rotating mode is a random rotating mode corresponding to one of the random parameters, and the driving circuitry controls the driving mechanism to rotate according to the random rotating mode; wherein the holding seat comprises a U-shaped framework and a flexible mandrel arranged in the framework for sheathing the automatic winding watch; and two relative side plates of the framework are respectively formed with an elastic locking arm used for fixing the holding seat on the rotating seat; wherein the tail end of the elastic locking arm towards the rotating seat is provided with a clamping bolt; and the rotating seat is provided with a clamping groove matched with the clamping bolt.
