Abstract

Adjacent cone type projections (2) are mutually joined by beads (4) provided at the inner panel (1) between the projections. The projections are provided at the inner panel at equal intervals.

Description

technical field [0001] The invention relates to an automobile engine cover, even if the pedestrian's head collides with any part of the automobile engine cover, the injury degree of the pedestrian's head due to collision can be reduced, which is beneficial to the safety of the pedestrian. Background technique [0002] Conventionally, as an automobile hood, a hood outer panel (external panel or outer panel, hereinafter referred to as outer panel) and an inner panel (inner panel or inner panel) as a reinforcing member for the outer panel are generally used. Panel, hereinafter referred to as the inner panel) is integrally joined, and a composite panel with a space between the two. [0003] In these composite panels, especially the inner panels, in order to achieve light weight, high-strength and high-formability aluminum alloy plates such as AA or JIS standard 3000 series, 5000 series, 6000 series, and 7000 series have begun to replace the previously used steel plate. [0004...
