The invention relates to an air buffer type train impact energy dissipation device, which is arranged at the front end of a train carriage. The device comprises a headstock cover which is arranged atthe front end of a train, is internally provided with an anti-collision support structure and is used for absorbing impact energy during impact, a safety air column structure which is used for absorbing and converting impact energy and comprises a plurality of hollow air columns with openings at the front ends, supporting columns with rear ends inserted in the air columns from the front openings of the air columns and air generation units arranged at the rear ends of the air columns and used for generating buffer air in rear end space. The rear ends of the air columns are fixed to the front end of the train carriage, and the front ends of the supporting columns are fixed to the headstock cover. Compared with the prior art, the device has the advantages of being small in occupied space, good in energy absorption effect, low in cost, high in reliability and the like.

    本发明涉及一种气体缓冲式列车撞击消能装置,设置在列车车厢前端,该装置包括:车头罩:安装在列车前端,且内部设有防撞支撑结构,用于在撞击时吸收撞击能量;安全气柱结构:用以将撞击能量吸收和转换,包括多根中空且前端开口的气柱、后端从气柱前端开口插设在气柱内的支撑柱以及设置在气柱的后端用以在后端空间内产生缓冲气体的气体发生单元,所述的气柱后端与列车车厢前端固定,所述的支撑柱前端与车头罩固定。与现有技术相比,本发明具有占用空间小、吸能效果好、成本低且可靠性高等优点。
