The invention discloses an energy absorption box of an automobile front anti-collision beam. The energy absorption box comprises a crumple energy absorption device and an air-pressure energy absorption device, wherein the crumple energy absorption device comprises a crumple pipe and a mounting plate which is fixedly connected with the front end face of the crumple pipe; the air-pressure energy absorption device comprises a barrel-shaped cylinder body which is coaxial with the central line of the crumple pipe; the rear end face of the crumple pipe is fixedly connected onto the front end face of the barrel-shaped cylinder body; the barrel-shaped cylinder body is internally provided with a piston; the front end face of the piston is fixedly connected with a piston rod; one end, far away from the piston, of the piston rod penetrates through the front end face of the barrel-shaped cylinder body and stretches into the crumple pipe, and is fixedly connected with the mounting plate; a pressure leaking hole communicated with an inner cavity of the barrel-shaped cylinder body is formed in the front end face of the barrel-shaped cylinder body; a connection hole is formed in the position, corresponding to the pressure leaking hole, of the piston; the connection hole can be used for communicating cavities, located on the two sides of the piston, of the barrel-shaped cylinder body. An energy absorption manner combining crumple energy absorption and air-pressure energy absorption is used for simultaneously converting collision energy, so that the conversion capability of an impact force is improved and the safety of vehicles is also improved.
