The invention relates to the technical field of explosion-proof armored vehicles, and particularly relates to a military vehicle lightning protection seat energy absorption device. The device comprises a fixing mechanism, a guide mechanism, a starting mechanism and an energy absorption mechanism. The fixing mechanism comprises an energy absorption device upper connecting block and a lower connecting block which are connected with corresponding mounting points of upper and lower cross beams of a seat framework through bolts; the guide mechanism comprises an elastic piece mounting block and an external box of the energy absorption device, and the elastic piece mounting block and the external box jointly restrain a motion trail of the energy absorption device in a working process of the energy absorption device; the starting mechanism comprises an elastic sheet and a constraint bolt and is connected with the elastic sheet mounting block; and the energy absorption mechanism comprises a steel belt and a steel belt limiting bolt, and the elastic piece mounting block is connected with a fixing and supporting mechanism after connecting the steel belt through the bolt. According to the lightning protection seat energy absorption device, buffering energy absorption is achieved through plastic deformation generated by the steel belt when the seat is impacted, an explosion impact is reduced, impact energy can be greatly relieved, and protection performance of the seat is effectively improved.
本发明涉及防爆炸装甲车辆技术领域,具体涉及一种军用车辆防雷座椅吸能装置。包括:固定机构、导向机构、启动机构和吸能机构。固定机构包括吸能装置上连接块和下连接块,分别通过螺栓与座椅骨架上下横梁对应安装点连接;导向机构包括弹片安装块和吸能装置的外部盒子,在吸能装置工作过程中,二者共同约束着该吸能装置的运动轨迹;启动机构包括弹片和约束螺栓,与弹片安装块连接;能量吸收机构包括钢带和钢带限位螺栓,弹片安装块通过螺栓将钢带连接后与固定支撑机构进行连接。本发明所提供的防雷座椅吸能装置,通过利用钢带在座椅受到冲击时产生的塑形变形来实现缓冲吸能,减小爆炸冲击,能够大幅度缓解冲击能量,有效提高座椅的防护性能。
