Rear structure for an electric vehicle having a rear rail which includes a rear portion, a front portion and a transition zone, such that in the event of a rear crash the rear portion and the transition zone are both able to deform to maximize the amount of energy absorption.

Rear structure for an electric vehicle

Front structure for an electric vehicle including a lower dash panel, a seat cross-member and a tunnel nose, such that the tunnel nose is designed to absorb energy in its front portion while resisting intrusion in its rear portion, optimizing the energy absorption in the part during a front crash and protecting the battery pack from being breached by the downward pushing effect of the lower dash panel.

Front structure for an electric vehicle

A side sill part () for an automotive vehicle comprises an outer sill member () and an inner sill member (), and defining between them an outer volume (). The side sill part also includes an external profile part (), defining with the inner sill member () an inner volume (), and a first profile part () extending in the outer volume (). The first profile part comprising at least one outer contact portion (), at least one inner contact portion (), and at least one joining wall () joining the outer contact portion () and the inner contact portion (). The side sill part further includes a second profile part () extending in the inner volume (), comprising at least one outer contact portion (), at least one inner contact portion (), and at least one joining wall () joining the outer contact portion () and the inner contact portion ().

A cross member () for a bumper beam includes an outer beam () with a main beam portion () comprising an upper beam wall (), a lower beam wall () and a front beam wall (), defining together a beam inner volume () open in a back direction, a reinforcement element () defining a reinforced area () of the outer beam (), located inside a part of said beam inner volume () and having a cross section, defining a reinforcement inner volume () open in the rear direction, a closing plate () closing at least a part of the beam inner volume (). The cross section of the reinforcement element () has a shape which is not matching the shape of the outer beam () in the reinforced area ().

Bumper beam having steel reinforcement

A cross member for a bumper beam includes an outer beam, an inner reinforcement element extending inside at least a part of the outer beam inner volume and comprising at least two reinforcement ribs protruding towards the front beam wall, the reinforcement ribs being connected together at least at their back end, opposite to the front beam wall, by an upper transversal branch and a lower transversal branch, the upper and lower transversal branches being attached respectively to the upper and lower beam flanges of the outer beam, wherein each reinforcement rib abuts the front beam wall and the length of the upper transversal branch is less than the length of the upper beam wall and the length of the lower transversal branch is less than the length of the lower beam wall, the lengths being measured in the longitudinal direction.

Bumper beam having an insert

A bumper beam is made of at least one rolled formed steel sheet containing an upper beam and a lower beam extending in a transversal direction, the upper beam and the lower beam each having a closed cross-section defined by a front wall, a rear wall, an upper wall and a lower wall, the upper wall and the lower wall joining the front wall to the rear wall, each of the front walls of the upper beam and of the lower beam containing a front rib extending transversally and towards the interior of the bumper beam. At least one of the upper wall of the upper beam, the lower wall of the lower beam, the rear wall of the upper beam and the rear wall of the lower beam further containing a rib extending transversally and towards the interior of the bumper beam.

Bumper beam having ribs on several walls of the bumper beam

A bumper beam made of at least one roll formed steel sheet is described. The bumper beam contains an upper beam and a lower beam extending in a transversal direction, the upper beam and the lower beam each having a closed cross-section defined by a front wall, a rear wall, an upper wall and a lower wall, the upper wall and the lower wall joining the front wall to the rear wall, and a central wall extending between the front walls, the rear walls of the upper beam and of the lower beam forming both the lower wall of the upper beam and the upper wall of the lower beam, the central wall extending in at least two different planes.
