Problems solved by technology

However, it is not known from the literature how to specifically construct such an energy-dissipating component
Furthermore, it is problematic that the component has a sufficient basic stiffness so that it does not yield under normal static loads, but only under impact loads, such as body or head impacts. Yield deformation occurs only upon impact

Embodiment Construction

[0020] The two FIGS. 1 and 2 show a hinge structure 1 for a (not shown in detail here) front panel. The hinge structure 1 is composed of an upper tie rod 2 welded or bolted to the front cover and a lower tie rod 3 bolted to the vehicle body. Two folding levers 4 , 5 , which are rotatably supported on the struts 2 , 3 respectively at joints 6 , 6 ′, 7 , 7 ′, extend between the two struts 2 , 3 . In order to move the front flap upwards or forwards when it is turned up, so as to prevent the rear edge of the front flap from colliding with a frame surrounding the front flap, one folding lever 4 is longer than the other folding lever 5 , and the two joints 6, 6' on the upper stay rod 2 are arranged closer to each other than the two joints 7, 7' on the lower stay rod 3. In this way, the swivel axis of the front flap is deflected forward when the front flap is opened.

[0021] According to the structure shown in FIG. 1 , a crash box 8 is located between the two struts 2 , 3 and near...

Abstract

The vehicle body has a crash box (8) mounted in or under the hinge unit (1) of the front bonnet. The crash box is stable yet plastically deforms above a certain crash load to reduce risk of injury with pedestrian etc. The crash box has at least two support walls (11, 12) arranged parallel to force direction. The crash box can be an integral part of a hinge unit.

Description

technical field [0001] The present invention relates to an automobile body, which has an elastically supported front cover, a hinge structure respectively between the sides of said body and said front cover and at least an assembly elastically deformable under load for supporting said bonnet on said vehicle body, wherein said bonnet can be opened about an axis of rotation defined by said hinge structure . Background technique [0002] A motor vehicle body of this type is known from DE 27 11 339 A1. The method of supporting the front panel proposed therein is based on the following considerations: In the event of a traffic accident, a vehicle always hits a pedestrian crossing the road from the front. The body and head of the pedestrian hit the front panel, causing serious injuries. Therefore, automobile manufacturing enterprises try their best to design the car body and especially the front structure with the front cover, although the injury to pedestrians cannot be elimin...
