Abstract
Provided are a collision energy absorption structure and a rail vehicle having the same. The collision energy absorption structure includes: a primary energy absorption structure, connected to a chassis boundary beam of a vehicle, the primary energy absorption structure having at least two spaced energy absorption cavities; an end energy absorption structure, the lower end of the end energy absorption structure being connected to the primary energy absorption structure; and a roof structure, the upper end of the end energy absorption structure being connected to the roof structure. The technical solution provided by the present invention can meet requirements of more complex road conditions.
