AI Technical Summary

Problems solved by technology

Therefore, its energy absorption potential is limited and the vehicle's passive safety performance is reduced
Furthermore, the fender retaining rigidity is still reduced even though its profile is L-shaped; since the area attached to the liner is far from the area attached to the fender

Embodiment Construction

[0039] In the following description, the longitudinal direction corresponds to the main direction of movement of the vehicle, and the front corresponds to its main direction of movement. The lateral direction is perpendicular to the lateral direction. The orientations mentioned below refer to the normal installation orientation in the vehicle.

[0040] figure 1 A front part 4 of the structure of a vehicle, in particular a motor vehicle, is shown. The front portion is viewed laterally from outside the vehicle. The front part corresponds to the front left part. Of course, the invention is also applicable to the front right part.

[0041] The structure may be the body of a motor vehicle, the body consisting of a joint of sheet metal which is stamped and then welded or glued to each other to form the frame of the vehicle. The frame supports various equipment of the vehicle including wheels (not shown), engine (not shown). This frame connects the front bumper to the rear bump...

Abstract

The subject of the invention is a vehicle structure, notably a motor vehicle bodyshell front part. The front part comprises: a front wing, a support (10) with a wing liner (12) and a reinforcer, and a join (8). The support (10) deforms, absorbing energy, in the event of a frontal impact against the vehicle. The join (8) comprises a first zone (30) fixed to the support (10), a second zone (32) holding the front wing, and two legs (24) connecting the first zone (30) to the second zone (32). The legs (24) are separated by a notch (22) and are separated from one another within the first zone (30) in order therein not to restrain the deformations of the support (10) during the frontal impact. The join (8) is intended to deform in the manner of a deliberate weak link in the event of an impact.

Description

technical field [0001] The invention relates to the field of vehicle frontal collision. More precisely, the invention relates to a front part of a motor vehicle structure with a front fender. The invention also relates to a motor vehicle. Background technique [0002] The body of a motor vehicle includes a front fender covering a front wheel. These fenders are secured to the fender liners, which support and reinforce the fenders. Intermediate supports are added at each interface between the fender and its liner to offset the area of ​​the fender held relative to the area of ​​the liner that actually supports the fender. [0003] Such an intermediate support should be rigid to allow good retention of the fender. However, the rigidity of the center support impairs the performance of the vehicle in a frontal collision. It must therefore be adapted to crashes to protect the vehicle's passive safety performance. [0004] Document FR 2 990 921 B1 discloses a motor vehicle fr...
