Auto rear beam assembly function
The main role of the rear beam protection assembly of the automobile includes the following aspects :
Disperse and absorb impact : The rear beam assembly is located at the rear of the vehicle and is usually made of high-strength steel or other wear-resistant materials. Its main function is to absorb and disperse the impact force through its own structural deformation when the vehicle is impacted, so as to protect the structure of the rear of the vehicle and the safety of the occupants .
Protect the safety of back-end electrical appliances : for electric vehicles, the rear protection beam assembly can not only protect the body structure in a high-speed collision, but also protect the back-end electrical equipment to prevent damage in the collision .
Affects aerodynamic performance and fuel efficiency : The design and shape of the rear beamguard assembly also affects the aerodynamic performance of the vehicle, which in turn affects fuel efficiency and other performance indicators .
reduce maintenance cost : in the case of low-speed collision, the rear protection beam assembly can absorb part of the collision energy, reduce the damage of the vehicle radiator, condenser and other important components, thus reducing the maintenance cost .
The rear bumper beam assembly is an important part of the automobile body structure, mainly including the rear bumper body, mounting parts, elastic cassette and other parts . Rear bumper body determines the shape and basic structure of the bumper, mounting parts such as mounting head and mounting column are used to fix the cassette on the rear bumper body, elastic cassette plays the role of buffering and fixing .
component
rear bumper body : this is the main part of the rear bumper assembly, determines the shape and basic structure of the bumper .
mounting part includes a mounting head and a mounting post for fixing the cassette seat on the rear bumper body .
elastic cassette : plays a role of cushioning and fixing, ensuring that the rear bumper can absorb energy and maintain stability when impacted .
anti-collision steel beam : can transfer the impact force to the chassis and disperse, enhance the anti-collision ability .
plastic foam : 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 improve the side stiffness and perceived quality, usually with support bars, welded convex and reinforcing bars .
upper body and lower body : constitute the main structure of the rear bumper .
decorative plate : located on the outside of the rear bumper, increase the beauty .
Function and effect
The main function of the rear bumper assembly is to absorb and mitigate the impact force from the outside to provide protection for the body. It can act as a buffer in the event of a collision and reduce the damage to the body. In addition, the rear bumper assembly also enhances the stability and safety of the vehicle through its structural and material design .
