The invention discloses a car bumper device with multiple buffering. The car bumper device comprises an outer cover plate, buffering springs, a connection frame, an anti-collision steel frame, gas cavities, a supporting plate, a support and an installation plate. The anti-collision steel frame is made of aluminum alloy. The gas cavities are filled with nitrogen gas and made of a wear-resisting and ageing-resisting rubber material. The buffering springs are clamped inside the connection frame, and the connection frame is made of plastic. The gas cavities are closed among the outer cover plate, the anti-collision steel frame and the supporting plate. A first buffering device comprises the buffering springs and the connection frame, and the reaction force of the buffering springs is utilized for buffering. A second buffering device comprises the anti-collision steel frame providing rigid supporting. A third buffering device comprises the gas cavities, and the air pressure is increased so as to stop further deformation when the gas cavities deform and become smaller. The first buffering device and the third buffering device adopt the energy absorption buffering mode and are supplementary. The second buffering device adopts the supporting buffering mode. The car bumper device is simple in structure and moderate in cost and adopts multiple buffering, and the personal safety of drivers and passengers is high.
