An energy absorbing device for subway vehicle includes a movable anti-climber, a fixed anti-climber, an energy absorbing honeycomb, at least one collapse tube, two sliding-groove assemblies and two guide sliding rails. As the first stage energy absorbing unit of the total structure, the energy absorbing honeycomb directly bears the collision impact transferred from the movable anti-climber. Through the deformation of the energy absorbing honeycomb itself under pressure, the collision kinetic energy transfers into internal energy of deformation and heat, thus realizing the energy absorbing buffering. As the second stage energy absorbing buffering unit, the at least one collapse tube further absorbs the collision energy, thus further buffering and protecting the underframe of the vehicle body, as well as ensuring that the impact energy performs a multistage and serial operation according to a predetermined direction and sequence, thereby ensuring the reliability of operation of the energy absorbing device.
