The invention relates to the technical field of anti-collision structures, and discloses an anti-collision structure for an airplane airborne data recorder, the anti-collision structure comprises a main body mechanism, a damping mechanism and an auxiliary mechanism, the damping mechanism is located below the main body mechanism, and the auxiliary mechanism is located above the damping mechanism; the main body mechanism comprises an anti-collision box, an outer sleeve, a compression spring and an anti-collision rod, the outer sleeve is fixedly installed at the upper end of the anti-collision box, the compression spring is fixedly installed at the lower end of the interior of the outer sleeve, the anti-collision rod is fixedly installed at the upper end of the compression spring, and the anti-collision plate is fixedly installed at the upper end of the anti-collision rod. According to the anti-collision structure for the airborne data recorder of the airplane, through the arrangement of the anti-collision box, the collision pressure borne by the data recorder body can be reduced, a compression spring and an anti-collision plate can reset after being subjected to the collision pressure, the buffering effect is achieved, a first encapsulating material layer and a rubber layer are protected, and the pressure resistance of the anti-collision plate is improved.

    本发明涉及防撞结构技术领域,且公开了一种用于飞机机载数据记录仪的防撞结构,包括主体机构、减震机构和辅助机构,所述减震机构位于主体机构的下方,所述辅助机构位于减震机构的上方,所述主体机构包括防撞箱、外套筒、压缩弹簧和防撞杆,所述外套筒固定安装在防撞箱的上端,所述压缩弹簧固定安装在外套筒内部的下端,所述防撞杆固定安装在压缩弹簧的上端,所述防撞板固定安装在防撞杆的上端。该用于飞机机载数据记录仪的防撞结构,防撞箱的设置,能够减轻于数据记录仪本体受到的撞击压力,压缩弹簧和防撞板能够,能够在受到撞击压力以后进行复位,起到缓冲的作用,防护灌封材料层一和橡胶层,增加了防撞板的抗压性。
