The anti-overloading active driving fan-shaped unfolding mechanism comprises a moving hinge seat, a fixed hinge seat, a moving gear, a fixed gear, an I-shaped connecting frame, a motor, a speed reducer, an idle running corner structure, a motor output shaft gear and a motor meshing moving gear. Two ends of the moving hinge seat are respectively connected with the I-shaped connecting frame through moving shafts; the moving gear is sleeved on the moving shaft; the two ends of the fixed hinge seat are connected with the I-shaped connecting frame through input shafts respectively; the fixed gear sleeves the input shaft and is meshed with the moving gear; the motor and the speed reducer are arranged in the I-shaped connecting frame, and the speed reducer is connected with an output shaft of the motor; the motor output shaft gear is connected with the output end of the speed reducer; the motor meshing movement gear sleeves the movement shaft and is meshed with the motor output shaft gear; and the idle running corner structure is arranged at any position from the output end of the speed reducer to a transmission chain of the motion hinge seat. The invention has the advantages of source drive, compact structure, capability of providing overtravel and motor overload prevention.
