The invention belongs to the field of civil aircraft structure design, and particularly relates to an aircraft leading edge explosive explosion bird impact resisting structure device and a using method. The device comprises a leading edge skin piece, a first assembly and a second assembly, wherein the first assembly comprises a wedge-shaped plate piece, a longitudinal reinforcement piece and a transverse reinforcement piece; a bending part for connection is arranged at the bottom of the wedge-shaped plate, and end plates are arranged at the two ends of the wedge-shaped plate; the second assembly comprises a box-shaped groove piece, a flexible supporting plate and a box-shaped cover piece. The box-shaped groove piece and the box-shaped cover piece are matched to form a box-shaped structure. The bending part at the bottom of the wedge-shaped plate is connected with the rear beam web, and the end plate is connected with the end rib web; explosive is placed in the middle of the bottom of the box-shaped groove piece of the second assembly, and the box-shaped groove piece is connected with the first assembly through a connecting bolt piece. The front edge skin piece is connected with the end rib piece and the front edge rear beam piece. Through the combined action of explosive explosion and structural protection, the effects of jointly resisting the impact of bird impact on the wing leading edge structure and protecting the wing leading edge rear beam are achieved.
