Abstract

A vehicle front body structure comprises an upper longitudinal beam and a upper fender rail (14) for supporting a fender of the vehicle, and the upper fender rail (14) extends in a longitudinal direction substantially parallel to the upper longitudinal beam and has a front end (14a) and a rear end (14b) spaced apart along the longitudinal direction. The resistance to plastic deformation of the upper fender rail (14) increases from the front end (14a) of the upper fender rail (14) to the rear end (14b) of the upper fender rail (14). The yield strength of the material of the rear section (62) isgreater than the yield strength of the material of the front section (60) and / or the rear section (62) has a greater wall thickness than the wall thickness of the front section (60).

Description

technical field [0001] The present invention relates to a vehicle front body structure, the vehicle front body structure includes an upper longitudinal beam (beam) and an upper fender rail (rail), the upper fender rail is used to support the vehicle fender, The upper fender side rail extends generally parallel to the upper side rail in the longitudinal direction, and the upper fender side rail has a front end and a rear end spaced apart in the longitudinal direction, the rear end being attached to a front pillar of the vehicle, and the upper fender side rail extends from the rear end toward the front of the vehicle. Background technique [0002] Conventionally, the front body structure of a vehicle is arranged to protect the vehicle occupants in the event of a full frontal collision by limiting any type of intrusion into the vehicle passenger compartment. To this end, the front body structure includes a front bumper, which is connected to the structural side members via cra...
