Description

Mounting bracket and fender mounting assembly

Technical Field

The invention relates to the technical field of automobile part structures, in particular to a mounting bracket and a fender mounting assembly.

Background

With the continuous increase of the keeping amount of domestic automobiles, a large number of accidents of collision between automobiles and pedestrians occur each year, and in order to protect lives and reduce injuries to pedestrians, new automobile evaluation regulations in China and Chinese insurance automobile safety indexes have included pedestrian protection as evaluation items so as to evaluate the advantages and disadvantages of automobile safety performance. Meanwhile, with the pushing implementation of national standards for pedestrian protection, further requirements are put forward on the pedestrian protection performance of automobiles.

The fender is used as an appearance piece and is arranged on two sides of the engine cover plate and above the tire. In a collision of an automobile with a pedestrian, the fender is also often located in the area where the head of the pedestrian is struck; the existing fender is generally and directly arranged on the mounting bracket in the shape of a Chinese character 'ji', weakening holes can be formed in supporting legs of the mounting bracket in the shape of the Chinese character 'ji', and meanwhile, the supporting legs are bent outwards, so that the damage to the head collision of pedestrians is reduced by reducing the supporting rigidity in the vertical direction.

The existing scheme has certain help to reduce the injury value of the head of the pedestrian, but also sacrifices the horizontal rigidity of a part of the bracket, so that the support surface of the bracket is misplaced with the hole site for mounting the fender, and the assembly is difficult; meanwhile, when the vertical rigidity is reduced, the fender bracket is easily deformed due to the opening and closing action of the engine hood, and the ground clearance between the fender and the engine hood is increased, thereby causing customer complaints. It is therefore necessary to design a fender mounting structure that can meet both the mounting and use requirements, while also greatly reducing pedestrian head impact injuries.
