In addition, described collision prevention girders is processed the radian that forms R=25m by hot bending.
According to said structure, because described collision prevention girders is processed the radian that forms R=25m by hot bending, therefore, collision prevention girders has certain resistance to bending, when vehicle generation offset frontal impact can load share the opposite side longeron some, make and hit side girder and be out of shape more stablely.
In addition, in " order " character form structure in described collision prevention girders cross section, vertically the thickness of structure is 3.0mm, and the thickness of horizontal structure is 1.8mm.
In addition, the yield strength of the aluminum alloy materials of described collision prevention girders is 300Mpa, tensile strength 560Mpa.
In addition, in " returning " character form structure of described energy-absorption box, " mouth " word structural thickness of outer ring is 2.0mm, and " mouth " word structural thickness of inner ring is 1.8mm.
In addition, the yield strength of the aluminum alloy materials of described energy-absorption box is 170Mpa, the aluminium of tensile strength 320Mpa.
In addition, all be connected by welding between described collision prevention girders and described energy-absorption box, described energy-absorption box and the described transom.
In addition, described transom is backboard.
