An embodiment vehicle body for an electric vehicle includes a fender apron upper part and an A pillar part positioned at a rear portion of the fender apron upper part, wherein a first load path is formed in a length direction of the vehicle body on an upper part of the fender apron upper part, wherein a second load path is formed in a vertical direction of the vehicle body along a connection portion of the fender apron upper part and the A pillar part, wherein a third load path connecting the first load path and the second load path is obliquely formed in a lower part of the fender apron upper part, and wherein a charging hole is formed between the first, second, and third load paths.

The invention relates to a front hinge pillar (9) of a vehicle, consisting of a stamped part comprising a central body (11) that is intended to extend vertically, so as to exhibit a lower end (13) and an upper end (15) and lateral edges, the front hinge pillar (9) being characterized in that it further comprises a front extension (17) extending from one of said lateral edges of said central body (11) such that said central body (11) and said front extension (17) form a single part. The invention also relates to the methods for producing such a front hinge pillar (9).

A vehicle front structure includes side frames in pairs, a bumper beam, a lower beam, coupling members in pairs, and gussets. The bumper beam and the lower beam extend in the vehicle width direction. Each coupling member extends in a vehicle upward-downward direction on an outer side of a corresponding one of the side frames in the vehicle width direction. The coupling members couple the bumper beam and the lower beam. A vehicle-front-side end part of each gusset is coupled to a middle part of a corresponding one of the coupling members in the vehicle upward-downward direction. A vehicle-rear-side end part of each gusset is coupled to the corresponding one of the side frames.

Unit with longitudinal beam and front plate for a motor-vehicle front structure, comprising a longitudinal beam in the form of a hollow profile and a front plate rigidly connected to a front end of said longitudinal beam. The longitudinal beam comprises a first beam element defining an upper wall, a lower wall and a first side wall of the longitudinal beam and a second beam element having a wall defining a second side wall of the longitudinal beam. The front plate has a rear face facing towards the longitudinal beam to which there are welded a first flange and a second flange which are separate from each other, for connecting the front end of the longitudinal beam. The first flange is a C-shaped bracket with an upper wall, a lower wall and a side wall respectively welded to the upper wall, the lower wall and the first side wall defined by said first beam element. The second flange is an L-shaped bracket, with a first wall welded to the rear face of the front plate and a second wall facing towards said second side wall defined by said second beam element. The above mentioned welds are electric spot welds. The two flanges may have different thickness.

A trailer frame includes a rear bolster, cross-members, and corner gussets extending forwardly from ends of the rear bolster. A rear impact guard includes a bumper positioned at the rear end of the trailer and spaced below the rear bolster, pair of outboard posts, and at least one inboard post. The outboard posts extend between the bumper and the rear bolster adjacent respective opposed distal ends of the bumper, and the inboard post extends between the bumper and the rear bolster between the outboard posts. Each of the pair of outboard posts has a lower end that overlaps with a respective mounting bracket that protrudes upwardly toward the rear bolster from the bumper such that mounting holes of the outboard posts align with mounting holes of the mounting brackets. A laterally-outboard panel of each mounting bracket extends obliquely from the bumper in a direction with a laterally-outward component.
