What is a car rear bumper bracket
Youdaoplaceholder0 Rear bumper bracket is a structural component installed on the rear bumper of a vehicle, which is mainly used to support the bumper and firmly connect it to the vehicle body. It is located at the bottom of the rear body of the car. Its main function is to support and protect the bumper, to disperse the impact force in the event of a collision, thus protecting the body safety .
The rear bumper bracket is usually made of metal or plastic, with certain strength and rigidity to ensure that it can withstand external impact forces in the event of a collision. Its design and material selection are crucial for improving the safety performance of a car .
In addition, the rear bumper bracket also plays an important role in automotive safety, which can disperse the impact force and effectively protect the vehicle and passengers .
The main functions of rear bumper brackets include supporting and protecting the bumper, absorbing external impact force, and protecting the vehicle and passengers in the event of a collision . The rear bumper bracket, as part of the rear bumper, not only supports and protects the bumper, but also absorbs and mitigates external impact force when the vehicle or driver is under impact force, thereby reducing injury to people inside .
Material and structure
The rear bumper bracket of a car is usually made of metal materials (such as steel or aluminum alloy), and the outer bumper housing is made of high-strength plastic, which has the characteristics of impact resistance and collision resistance. The inner crash beams are made of metal to absorb energy in the event of a collision and protect the rear structure .
Design and Function
Some innovative car rear bumper brackets also include buffer plates and support springs, which can deform when impacted. Together with the support springs, they form a two-level buffer, effectively alleviating external impact forces and enhancing stability and impact resistance. This design reliably absorbs shock in the event of a minor collision, thus better protecting the car .
