The invention provides a telescopic aluminum honeycomb buffer device. The device comprises a telescoping mechanism and an aluminum honeycomb buffer, wherein the telescoping mechanism comprises a sleeve set and a sleeve set tail end cover mounted at the tail end of the sleeve set; the sleeve set comprises at least two hollow sleeves which are coaxially connected in a sleeved mode; the adjacent sleeves can slide relatively; a high-pressure inflation port is formed in the wall of the sleeve close to the sleeve set tail end cover; and the aluminum honeycomb buffer is arranged in the sleeve away from the sleeve set tail end cover in a sliding and sleeve-joint mode. The telescopic aluminum honeycomb buffer device is simple and compact in structure, can stretch and contract, can be mounted in anaircraft with small space, can obtain a large buffer stroke and is beneficial for safe landing of the aircraft; by arranging the high-pressure inflation port, high-pressure air can be injected into the telescoping mechanism; when the aircraft lands normally, an aluminum honeycomb is pressed to achieve an energy absorption function; and when the aircraft lands with a heavy load accidentally, an internal air cavity of the telescoping mechanism can be compressed to achieve an energy absorption effect. Therefore, the function of preventing crash can be achieved, and the landing safety of the aircraft is enhanced.

    本申请提供一种伸缩铝蜂窝缓冲装置,包括伸缩机构和铝蜂窝缓冲器;伸缩机构包括套筒组及安装在套筒组尾端的套筒组尾端盖;套筒组包括至少两节同轴套接的中空套筒;相邻的套筒之间可相对滑动;靠近套筒组尾端盖的套筒的筒壁上开设有高压充气口;远离套筒组尾端盖的套筒内滑动套接有铝蜂窝缓冲器。该伸缩铝蜂窝缓冲装置结构简单紧凑、可伸缩,既可安装于空间狭小的飞行器内,又可获得较大的缓冲行程,有利于飞行器安全着陆;通过设置高压充气口,高压气体可充入伸缩机构内部,飞行器正常着陆时,铝蜂窝被压溃产生吸能作用,当飞行器意外重载着陆时,伸缩机构的内部气腔可被压缩,产生吸能效果,从而可以起到防坠毁作用,增加飞行器着陆的安全性。
