Abstract
The present invention relates to a deformation device for anti-collision on sides of a passenger vehicle and a passenger vehicle with the deformation device for anti-collision on sides, wherein the deformation device for anti-collision on sides is arranged between a power passage of a vehicle body and B columns on sides of the vehicle body. The invention is characterized in that the deformation device for anti-collision on sides comprises an energy absorbing box and two lateral supporting rods, wherein the energy absorbing box is provided with a cavity shell structure and is arranged above the power passage of the vehicle body and the lateral supporting rods are respectively arranged on both sides of the energy absorbing box; one end of each lateral supporting rod is fixedly connected with the energy absorbing box and the other end is fixedly connected with the B columns on both sides of the vehicle body. In the process that a side collision accident of the vehicle occurs, one side B column and one side lateral supporting rod are hit so that the power passage, the energy absorbing box, the floor of the vehicle body, the other side lateral supporting rod without collision and the other side B column without collision are successively and sequentially deformed. The integral structure of the vehicle body resists and hit the side deformation to decrease the amount of deformation when the side B columns are hit, to reduce the deformation speed of the B columns and doors, and to delay the time when sides have collision to hit occupants.
