What is the rear bumper assembly of the car
The rear anti-collision beam assembly is an important safety device located at the rear of the vehicle, and its main function is to absorb and conduct the impact force in the collision to protect the safety of the vehicle and passengers.
Definition and function
The rear anti-collision beam assembly is an important part of the rear end of the vehicle, and its main functions include:
low speed collision protection : in low speed collision, the rear anti-collision beam can effectively absorb the collision energy, reduce the damage to the longitudinal beam of the body and reduce the maintenance cost .
high-speed collision protection : in high-speed collision, the rear anti-collision beam assembly can absorb energy and conduct impact force to protect vehicle structure and passenger safety .
Structural composition
The rear anti-collision beam assembly usually consists of the following parts:
main beam : mainly bear the impact force.
energy absorption box : absorbs energy in low-speed collisions to reduce damage to the body.
connection plate : Fix the anti-collision beam on the car body .
Materials and selection strategies
There are two main materials for the rear anti-collision beam:
aluminum alloy : mostly used in high-end models and electric models, because of its lightweight and high strength .
cold rolled steel plate : common materials for ordinary models, through stamping forming, stable structure .
Installation and maintenance
The installation of the rear anti-collision beam assembly is usually bolted for easy removal and replacement. This design is not only easy to repair, but also quickly absorbs energy in a crash, protecting the vehicle structure .
The main functions of the rear anti-collision beam assembly include absorbing and disperting the impact force during a collision, reducing the damage to the rear structure of the vehicle, and protecting the safety of passengers .
The rear anti-collision beam is usually located at the rear of the vehicle. When the vehicle crashes, it can absorb and disperse the impact energy, protect the integrity of the body structure, and reduce the risk of injury to the occupants .
Working principle and material
Rear anti-collision beams are usually made of high-strength steel or aluminum alloy materials, which have high strength and impact resistance, can effectively absorb impact energy and reduce vehicle deformation .
The design and layout of the rear anti-collision beams are rigorously tested and optimised to ensure that energy is efficiently dispersed and absorbed in the event of a collision .
The role of different accident scenarios
low-speed collision : In low-speed collision scenarios, such as rear-end collision accidents on urban roads, the rear anti-collision beam can directly withstand the impact of the collision and avoid the damage of important vehicle components such as radiators and condensers. At the same time, the deformation of the anti-collision beam can absorb part of the collision energy and reduce the impact on the body structure .
high-speed collision : in high-speed collision, although the rear anti-collision beam can not completely prevent the damage of the vehicle, it can transfer part of the energy to other parts of the body and slow the impact of the collision energy on the passengers .
Care and maintenance advice
Although the rear anti-collision beam plays an important role in the collision, its design and manufacturing process have a significant impact on its effect. Therefore, the selection of high quality materials and reasonable structural design is the key to ensure the effectiveness of the rear anti-collision beam .
In addition, regular inspection of the status of the anti-collision beam to ensure its integrity is also one of the important measures to ensure vehicle safety .
