Car front wall upper plate assembly and car

Abstract

The invention discloses a car front wall upper plate assembly. The car front wall upper plate assembly is of an opening suspension structure, namely, the bottom of a front baffle plate is suspended and an opening is formed between the bottom of the front baffle plate and the bottom of a rear support plate. Correspondingly, when an adult pedestrian is hit by the front part of a car, the pedestrian body falls toward the car and the pedestrian head hits against the front baffle plate of the car front wall upper plate assembly; as the suspended bottom of the front baffle plate is not restricted by other structures, the front baffle plate is capable of recessing toward the rear support plate under the hitting of the pedestrian head, energy absorption is carried out on the hitting of the pedestrian through the deformation of the front baffle plate due to the recession toward the rear support plate and the damage caused to the pedestrian head can be reduced. Moreover, through a reinforcing plate arranged on the rear support plate, the strength loss generated to the car front wall upper plate assembly by the opening suspension structure can be made up to a certain extent, so that the strength requirement of the car front wall upper plate assembly is considered while the pedestrian safety is ensured.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile front wall upper panel assembly and an automobile using the automobile front wall upper panel assembly. Background technique [0002] The upper panel assembly of the cowl of the car is an important part of the front part of the car body, which can make the front part of the car body have sufficient strength and can support the front windshield and front grille of the car. Therefore, when the prior art designs the upper panel assembly of the cowl of the automobile, it usually only pays attention to how to improve the strength of the upper panel assembly of the cowl of the automobile. [0003] Specifically, in order to make the automobile cowl upper panel assembly have sufficient strength, the prior art usually sets the automobile cowl upper panel assembly as a closed structure. [0004] See figure 1 and figure 2 , the automobile cowl upper panel assembly of the closed ...

AI Technical Summary

Problems solved by technology

[0007] However, while the existing technology satisfies the strength of the upper panel assembly of the automobile cowl, it ignores the protection of pedestrians.

For adult pedestrians, when their body is bumped by the front of the car, they will fall towards the car, and after the body falls, their head will hit the front baffle 12 of the front wall upper panel assembly of the car. Due to the closed structure adopted by the upper panel assembly and the reinforcing effect of the reinforcing plate 13 on the front baffle 12, the front baffle 12 will basically not be recessed toward the rear support plate 11 due to the impact of the head of the pedestrian. It is impossible to absorb the impact of the pedestrian's head through the deformation caused by the recess of the rear support plate 11, thereby causing great damage to the pedestrian's head
