What is the rear protection beam assembly
Auto rear bumper anti-collision beam assembly is an important part of the car, mainly including the following parts:
Rear bumper body : This is the main part of the rear bumper assembly, which determines the shape and basic structure of the bumper .
mounting kit : includes a mounting head and a mounting post for securing the cassette to the rear bumper body. The mounting head collides with the rubber buffer blocks on the taildoor, protecting the front and rear ends .
Elastic cassette : used to secure and connect the rear bumper components .
anti-collision steel girder : located inside the rear bumper, made of high-strength steel, can absorb and disperse the impact energy during a collision, protecting the body .
plastic foam : used to absorb and disperse the impact energy, protect the body .
bracket : used to support the bumper and enhance its stability and strength .
reflectors : improve visibility for driving at night .
mounting hole : used for connecting radar and antenna components .
reinforcing plate : to enhance the side stiffness and perceived quality, usually provided with support bars, welded convex and reinforcing bars .
decorative plate : located on the outside of the rear bumper, play a beautiful role .
The role and importance of anti-collision steel beams
Anti-collision steel beam is the first passive safety barrier of the car, mainly located in the front and rear of the body. When the vehicle crashes, it absorbs and disperses the collision energy through its own structural deformation, thereby reducing the damage to the main structure of the body and protecting the safety of the passengers in the car .
The anti-collision steel beam can directly withstand the impact force in the low-speed collision to avoid the damage of important components; In high-speed crashes, although it can not completely prevent vehicle damage, it can disperse the collision energy and reduce the impact on the passengers in the car .
The main role of the rear anti-collision beam assembly of the automobile includes the following aspects :
Absorb and disperse collision energy : in the event of vehicle collision, the rear anti-collision beam absorbs and disperses the collision energy through its own structural deformation to reduce the damage to the rear structure of the vehicle. It can disperse part of the energy along the structure of the body, slowing the impact of the collision energy on the passengers in the car .
Passenger safety : Rear fender beams protect passengers in a collision. It reduces the damage to the rear structure of the vehicle by absorbing and disperzing the collision energy, thus reducing the injuries suffered by the passengers in the vehicle .
reduce maintenance cost : in the case of low-speed collision, the rear anti-collision beam can directly bear the impact of the collision, so as to avoid the damage of the important parts of the rear of the vehicle, such as the radiator and condenser. In this way, the vehicle may only need to replace the anti-collision beam or carry out simple repairs, thus greatly reducing the maintenance cost .
Protect body structure and electrical equipment : For vehicles such as electric vehicles, rear anti-collision beams also play a role in protecting the safety of back-end electrical appliances. It absorbs and disperses energy during a collision, protecting the body structure and electrical equipment from damage .
