The invention discloses an energy absorption buffering device, an anti-collision structure and a vehicle. The absorption buffering device comprises a casing, and a buffering piece which can be movably inserted in the casing along an axial direction, wherein first buffering areas accommodating first fluid media are formed between the buffering piece and the casing in a limit manner, a second buffering area accommodating a second medium is formed in the buffering piece, when the buffering piece is inserted inwards in the casing, the first fluid media can enter the second buffering area through a throttling structure between the first buffering areas and the second buffering area. When collision occurs, the buffering piece is prevented from being inserted in the casing through the moving damping and the resistance to compression of the first fluid media; when the collision is more heavy, the pressure of the first fluid media rises, and the first fluid media can enter the second buffering area through the throttling structure, so that the resistance to the buffering piece entering the casing is increased. Therefore, through the artful structure of the energy absorption buffering device disclosed by the invention, the effects of energy absorption and buffering can be effectively improved, and the practicability is high, so that the anti-collision property and the safety of the vehicle are higher.
