The invention discloses a cowcatcher with a drawer type honeycomb energy absorption structure. The cowcatcher comprises a cowcatcher main body, a honeycomb energy absorption unit and a mounting seat.A honeycomb groove with an opening in the front is formed in the middle of the cowcatcher main body, the honeycomb groove is in sliding fit with the honeycomb energy absorption unit to form a drawer type structure, and when an inner portion of a center area of the cowcatcher is seriously impacted, a front cover plate assembly retreats along a sliding rail, honeycombs are compressed, impact energyis effectively absorbed and a rear supporting frame structure and a vehicle body structure are protected from damage. The cowcatcher is simple in structure, and a current situation that an overall size is large due to a fact that an energy absorption honeycomb of an existing cowcatcher is arranged in front of a front baffle is changed. The cowcatcher is convenient to maintain, the energy absorption unit can be independently replaced by detaching the front cover plate, overall detachment is not needed, and the cowcatcher is almost free of maintenance in normal use.

    一种抽屉式蜂窝吸能结构排障器,包括排障器主体、蜂窝吸能单元、安装座,排障器主体中间为前面开口的蜂窝槽,蜂窝槽与蜂窝吸能单元滑动配合,形成抽屉式结构,当排障器中心区域内受到较大撞击时,前罩板组成沿滑轨后退,压缩蜂窝,有效吸收撞击能量,保护后部支撑架结构及车体结构不损坏。本发明所述排障器结构简单,改变了以往排障器吸能蜂窝设置在前挡板前面导致整体体积较大的现状。排障器维修方便,通过拆卸前罩板组成,能够实现吸能单元的单独更换,不需要整体拆除,正常使用几乎免维护。
