The invention relates to the field of flight control, in particular to a design method of a flap driving mechanism and the flap driving mechanism, and aims to solve the problem that the driving mechanism is low in use efficiency when an aircraft flap is loaded heavily and deflects a large angle. According to the design method of the flap driving mechanism, on the basis that a universal coupling is in an original state, a driven shaft is rotated by a preset angle around a hinge point in the anti-clockwise direction, and the current state of the universal coupling is used as the original state to be designed, so that the efficiency loss of the universal coupling is reduced when the flap is driven to rotate by the same angle, and the efficiency of the driving mechanism is greatly improved; meanwhile, on the premise that the external driving load of by the flap driving mechanism remains unchanged, the design load of the driving mechanism is reduced, the design weight of the driving mechanism is reduced, and the reliability of the driving mechanism is improved; the principle is simple and practical, and easy to implement.
