Problems solved by technology

[0005]However, the transformation of the body structure of the automobile hood is only the interior of the hood, and the external structure has not changed, so that the collision protection has not been improved, and the bouncing Type hoods are mainly divided into gunpowder type and mechanical type. The gunpowder type pop-up device cannot be reused and the cost is high
However, the traditional mechanical pop-up device has the problem of not being able to control the acceleration of the pop-up

Embodiment Construction

[0056] The present invention will be described in further detail in conjunction with the following, so that those skilled in the art can implement it with reference to the description.

[0057] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the present invention provides a new type of engine hood with an inwardly recessed outer panel, which specifically includes a filling layer 130, an outer panel 110 and an inner panel 120 arranged in sequence from top to bottom, and the outer panel 110 has an inwardly arranged depression. , the inner panel 120 plays a supporting role, and the filling layer 130 is arranged in the depression on the outer panel 110 to form a new engine cover.

[0058] Among them, such as Figure 5 , Image 6As shown, the inner panel 120 is different from the traditional inner panel in that it only retains the frame of the inner panel and does not have the ribs of the traditional inner panel. The force transmitted by the plate 110 plays a ce...

Abstract

The invention discloses a novel engine hood with an inward-sunken outer plate, and the engine hood comprises an inner plate which is of a frame structure; an outer plate which comprises a plate body, an extending part and a sunken part, wherein the extension parts are arranged at the two ends of the plate body in a bent mode, the extension parts are connected with the inner plate, and the sunken part is arranged in a head impact area on the plate body; and a filling layer, wherein one side of the filling layer is matched with the concave part, and the other side of the filling layer and the plate body form the same plane. The engine hood has the characteristics of reducing collision damage and improving the light weight of the engine hood.

Description

technical field [0001] The invention relates to the technical field of engine parts, and more specifically, the invention relates to a new type of engine cover with an inwardly recessed outer plate. Background technique [0002] In recent years, pedestrian protection in automobile accidents has been paid more and more attention, and pedestrian protection performance is gradually being paid attention to as an indicator of the grade of automobile hoods. On the one hand, due to the increase in engine output of automobiles, the size of the engine has gradually increased, and the number of components in the engine room has gradually increased due to the multi-function, so the space under the hood required for pedestrian protection has also decreased. [0003] Generally speaking, when a moving car collides with a pedestrian, due to the effect of inertia, the upper body of the pedestrian will turn around in the direction of the vehicle body, causing the head of the pedestrian to co...
