Abstract

The invention discloses an engine cover inner plate structure. The engine cover inner plate structure comprises an engine cover inner plate body, a rib beam and a protruding structure are arranged onthe engine cover inner plate body, a rib beam installation space is defined by the rib beam and the interior of the protruding structure, and buffering holes used for absorbing energy are formed in the protruding structure. The buffering holes in the inner plate of the engine hood can achieve a good buffering and energy-absorbing effect when the head of a pedestrian collides with the engine hood,and the injury degree of the head of the pedestrian is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an inner panel structure of a hair cover. Background technique [0002] The hair cover is an important structural part of the car. Its design must not only meet the requirements of stiffness, mode, anti-dent, strength of the installation point, and snap-off, but also need to meet the feasibility of stamping and transportation. Since C-NCAP introduced the pedestrian protection evaluation system in 2018, the C-NCAP pedestrian protection requirements have been added without changing other performance target values. It is worth mentioning that the pedestrian protection performance and other performances of the hair cover, especially the anti-dent performance, are contradictory, and it is extremely difficult to balance them. The hair covers currently on the market are either made too hard to meet the anti-dent requirements; or made too soft to meet the goal of pedestr...
