The invention discloses an aircraft lightning protection composite material wing box, and relates to the technical field of wing boxes, the aircraft lightning protection composite material wing box comprises a support assembly used for supporting and protecting parts needed for forming the wing box; the reinforcing assembly is located on the inner side of the supporting assembly; the buffering assembly is located on the outer sides of the supporting assembly and the reinforcing assembly; the reinforcing assembly comprises a wing rib, and a plurality of sets of holes are evenly formed in the two sides of one end of the wing rib. The movable wing plate affected by impact force floats up and down under the action of the elastic piece, the elastic piece is used for buffering the floating wing plate, the direct impact force of the floating wing plate on the skin is reduced, meanwhile, the floating range of the movable wing plate is limited and supported through the movable groove and the movable block, the service life of the skin is prolonged, and the service life of the skin is prolonged. And if a certain movable wing plate is damaged, the movable wing plate can be independently replaced, the whole skin does not need to be replaced, the cost is reduced, and meanwhile the impact force borne by the skin can be smaller through the elastic piece.

    本发明公开了一种飞机防雷击的复合材料机翼翼盒,涉及机翼翼盒技术领域,包括:支撑组件,用于对构成机翼翼盒所需零部件进行支撑以及防护;加固组件,位于支撑组件的内侧;缓冲组件,位于支撑组件和加固组件的外侧;所述加固组件包括翼肋,所述翼肋一端的两侧皆均匀设置有多组孔洞。本发明,使受撞击力影响的活动翼板在弹性件的作用下上下浮动,利用弹性件对浮动的翼板起到缓冲的作用,降低其对蒙皮的直接冲击力,同时利用活动槽和活动块对活动翼板的浮动范围进行限位支撑,提高了蒙皮的使用寿命,若某个活动翼板受损后可单独对其进行更换,不需要更换整个蒙皮,降低了成本,同时又能利用弹性件使蒙皮受到的冲击力更小。
