AI Technical Summary

Technical Problem

Existing vehicle hood designs struggle to achieve significant weight reduction while maintaining rigidity and durability, which is crucial for improving emission values and road handling, especially in electric and hybrid vehicles.

Method used

A hybrid vehicle hood structure is introduced, featuring an outer steel sheet metal panel and an inner panel with strategically formed support openings and lightweight supports made of aluminum or composite materials, which are connected to provide enhanced rigidity and weight reduction.

Benefits of technology

The hybrid structure effectively reduces the weight of the vehicle hood while maintaining or improving its rigidity, thereby enhancing the vehicle's emission performance and range, especially in electric and hybrid vehicles.

Abstract

The invention is a method to be applied to hoods (A) consisting of an outer panel (10) and an inner panel (20) structure, particularly to provide weight reduction in the hood (A) sections of vehicles; characterized in that from the outer panel (10) and inner panel (20) which are connected to each other, the inner panel (20) surface is formed during the shaping process of the said inner panel (20) to include multiple support openings (201), and characterized by connecting supports (30) made of material lighter than the inner panel (20) in sections where strength is needed on the outer panel (10) and inner panel (20) that are connected to each other.
