AI Technical Summary

Problems solved by technology

While weight reductions can be achieved by conventionally replacing steel components with aluminum or plastic counterparts, this substitution also results in increased yield deformability
As a result, the cover is already damaged in the event of a minor impact, which results in high repair costs for the user
Conversely, higher yield deformability leads to pedestrian accidents in which the pedestrian's head hits the non-deformable body part, resulting in the revoking of the vehicle's road permit

Embodiment Construction

[0037] figure 1 Shows a perspective view of two C-shaped pipes 1 , 2 whose irregular and to-be-formed covers are obtained by heat-forming of extruded pipes, preferably aluminum pipes Structural design matching the shape. Each of the two tubes 1 comprises a lateral side 3 and front and rear arms 4 , 5 starting from the ends of the lateral side 3 . The arms 4 , 5 of the right-hand pipe 2 have an essentially identical or only continuously varying cross-section at least in the region of their free ends and are open at their tips so as to form the socket 6 . The arms 4, 5 of the pipe fitting 1 are mirror-symmetrically formed with the arms 4, 5 of the pipe fitting 2 from the lateral edge 3 to the shoulder 7 respectively; The cross section of is dimensioned so that it can be inserted into the socket 6 of the pipe 2 . When the free ends of the arms 4, 5 of the pipe 2 touch the shoulders 7, the frame 9 formed by the pipes 1, 2 achieves its prescribed dimensions and the pipes 1, 2 ca...

Abstract

A cover, in particular a front cover, for a motor vehicle body, the cover having an outer skin (23) and a reinforcement structure covered by the outer skin (23), wherein the reinforcement structure comprises a base plate (13) peg-like sheet (10) and pegs (14) extending from said base plate (13) and extending under said outer skin (23) and a second sheet (10'), The tops (15) of the pegs (14) are fixed to the second sheet (10').

Description

technical field [0001] The invention relates to a cover, in particular a front cover, for a motor vehicle body. Background technique [0002] From the document DE 10 2004 053 248 A1 a cover is known which has an outer skin and a reinforcing structure covered by the outer skin, wherein the reinforcing structure comprises a frame which is deep-drawn from a planar material and a frame mounted on the frame. Plates in the window. In order to fasten the supports made of foam material arranged between the sheet metal and the outer skin, pegs are embedded in the sheet metal, each receiving a foam body. [0003] The body cover should have a weight as low as possible, on the one hand, be strong enough to withstand minor impacts without damage during use, and on the other hand meet the strict requirements regarding the deformation behavior of the cover in accordance with the legal provisions for pedestrian protection. According to strict requirements, pedestrians who hit the cover ar...
