Embodiment Construction

[0035] In the following description, the terms "upper", "lower", "front", "rear", "transverse" and "longitudinal" are defined according to the general orientation of the vehicle where they are installed. More specifically, the terms "upper" and "lower" are defined according to the height direction of the vehicle, the terms "front", "rear" and "longitudinal" are defined according to the front / rear direction of the vehicle, and the term "transverse" is Defined according to the width of the vehicle. By "substantially parallel" or "substantially perpendicular" is meant an orientation that may deviate from parallel or perpendicular by no more than 15°.

[0036] More specifically, the terms "fracture strain" and "critical bending angle" mean "Methodology to assess fracture during crash simulation: fracture Strain criteria at fracture and their calibration (Methods for assessing fracture during crash simulation: Fracture strain criteria and their calibration)" and the criteria for f...

Abstract

A front structure for an electric vehicle, the front structure comprising a lower instrument panel, a seat cross member and a passage nose such that the passage nose is designed to absorb energy with a front portion thereof while resisting intrusion with a rear portion thereof, thus, energy absorption in the portion during a frontal impact is optimized and the battery pack is prevented from being damaged by the downward pushing effect of the lower dashboard.

Description

technical field [0001] The invention relates to a front structure for a motor vehicle having an electric powertrain, hereinafter referred to as an electric vehicle. The invention also relates to a method for producing such a front structure. Background technique [0002] Environmental concerns and regulations related to increasing levels of carbon dioxide in the atmosphere and local air pollution levels are driving the rise of electric mobility vehicles. Compared to conventional internal combustion engine vehicles, electric vehicles have smaller engines, no fuel tanks, and no exhaust systems. Electric vehicles, on the other hand, have fairly large battery packs, which are absent in internal combustion engines. [0003] These marked differences are causing changes in the global architecture of motor vehicles. Electric vehicle designs must accommodate new powertrains and must take advantage of the extra space provided by smaller engines and the absence of exhaust systems an...
