Description

A mounting bracket and fender mounting assembly

technical field

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

Background technique

With the continuous growth of domestic car ownership, a large number of car-pedestrian collision accidents occur every year. In order to protect lives and reduce pedestrian injuries, my country's new car evaluation regulations and China Insurance Automobile Safety Index have included pedestrian protection as an evaluation Items to evaluate the pros and cons of automobile safety performance. At the same time, with the promotion and implementation of national standards for pedestrian protection, further requirements are put forward for the pedestrian protection performance of automobiles.

As an exterior part, the fenders are installed on both sides of the engine cover and above the tires. In a collision between a car and a pedestrian, the fender is often in the area where the head of the pedestrian hits; the existing fenders are generally directly installed on the mounting bracket in the shape of "几". Weakening holes can be opened on the supporting legs, and at the same time, the supporting legs are bent outwards, so as to reduce the damage to the head collision of pedestrians by reducing the supporting stiffness in the vertical direction.

Although the existing scheme is helpful to reduce the pedestrian head injury value, it also sacrifices a part of the horizontal stiffness of the bracket, resulting in misalignment between the support surface of the bracket and the mounting hole of the fender, making assembly difficult; at the same time, when the vertical When the stiffness decreases, due to the switch action of the engine hood, it is easy to cause deformation of the fender bracket, increase the gap between the fender and the engine hood, and cause complaints from customers. Therefore, it is necessary to design a fender mounting structure that can not only meet the installation and use requirements, but also greatly reduce pedestrian head collision injuries.
