Support structure for front area of motor vehicle, has wall area, in bottom tunnel, shifting backwards in bottom tunnel, in case of impact, where area is deformed based on its form and material under impact conditional arrangement force

摘要

The structure has a wall area, in a bottom tunnel (2), attached to an area of a motor drive unit, shifting backwards in the bottom tunnel, in case of impact. The wall area can be deformed based on its form and material under impact conditional arrangement force of the motor drive unit. The wall area of the bottom tunnel allows deformation in a longitudinal and cross sectional direction of the vehicle.
