What is the front bumper frame
The front bumper frame, also known as the vehicle anti-collision beam, is a core component of the vehicle's safety structure. It is located at the front of the vehicle and connected to the bumper housing. Its main function is to absorb and disperse the energy generated by the collision to protect the safety of the vehicle body and occupants.
The front bumper frame is usually composed of the main beam, energy-absorbing box and mounting plate. These components work together to deal with vehicle collisions. In the event of a low-speed collision, the main beam and the energy-absorbing box can efficiently absorb the collision energy and reduce the damage to the longitudinal beam of the vehicle body caused by the impact. In addition, the front bumper not only serves a decorative function, but more importantly, it can absorb and mitigate external impact forces, protecting the vehicle body from damage. It is an important device for ensuring the safety of the vehicle and its occupants.
If the front bumper frame is damaged, it is recommended to go to an auto parts market or 4S store immediately for repair or replacement. For small-scale cracking, welding repair can be attempted. For large-scale cracking or cases that exceed the repair standards, replacement should be carried out. During the repair process, for plastic bumpers, it is recommended to use reliable structural adhesives for bonding and painting. Metal bumpers should be welded in professional repair shops.
After repairing the cracks and deformations of the bumper, it is also necessary to pay attention to the treatment of the car's paint surface. To ensure the paint surface effect, the treatment should be carried out in a dust-free environment. Therefore, it is recommended to entrust it to a professional auto repair shop.
The bumper frame is not the same as the anti-collision beam. Its original design intention is to protect the appearance structure of the front and rear parts of the vehicle. The anti-collision beam, as a crucial safety device, is designed to absorb the impact energy when a vehicle collids, thereby reducing the damage to the longitudinal beams of the vehicle body and ensuring the safety of the occupants inside. This type of beam is usually hidden inside the bumper and the car door. When encountering a significant impact force and the elastic material can no longer absorb more energy, the anti-collision beam will play a crucial role in protecting the occupants inside the vehicle. It is worth noting that not all vehicles are equipped with anti-collision beams. Common materials for them include metals such as aluminum alloy and steel pipes. In some high-end car models, aluminum alloy materials are more commonly used, while in some other models, hard plastics may be chosen. Nowadays, an increasing number of car manufacturers are beginning to install side door anti-collision beams on the side doors of their vehicles to enhance the structural strength of the vehicle's sides. This side door anti-collision beam, also known as the door anti-collision beam, can effectively protect the interior components from damage in low-speed collisions. In fact, when a vehicle hits a fixed object, the protective effect of the anti-collision beam is particularly significant. Compared with vehicles without anti-collision beams, it can significantly reduce the external impact force on occupants. Therefore, in automotive safety systems, anti-collision beams play a crucial role.
The differences between anti-collision beams and bumpers are mainly reflected in position, material and function .
Youdaoplaceholder0 Location : The bumpers are located outside the front and rear of the vehicle, and the bumpers are hidden inside the bumpers or inside the doors;
Youdaoplaceholder0 Material : Bumper is mostly plastic (such as ABS engineering plastic), anti-collision beam is mostly high-strength metal (steel or aluminum);
Youdaoplaceholder0 Function : The bumper is used to absorb minor impact energy and protect pedestrians, and the anti-collision beam is used to protect occupants against high-speed impacts.
Detailed analysis
Location difference
Youdaoplaceholder0 Bumper : Installed at the front and rear ends of the vehicle, connected to the headlights, it is an exterior part and is directly visible.
Youdaoplaceholder0 Anti-collision beams : They are divided into front and rear anti-collision beams (hidden inside the bumper) and door anti-collision beams (inside the door), both are concealed structures.
Materials & structure
Youdaoplaceholder0 Bumper : Modern cars are mostly made of plastic (such as ABS engineering plastic), consisting of outer panels, cushioning materials and metal crossbeams, which are both lightweight and aesthetically pleasing.
Youdaoplaceholder0 Anti-collision beam : The main beam is made of high-strength steel or aluminium alloy and is equipped with energy-absorbing boxes (crumble structure) to disperse the impact force.
Function and protected object
Youdaoplaceholder0 Bumper :
It mainly deals with low-speed collisions (such as scratches), absorbs energy through elastic deformation, and reduces vehicle damage.
The design focuses on pedestrian protection to reduce the harm caused by collisions to pedestrians.
Youdaoplaceholder0 Anti-collision beam :
During high-speed collisions, the impact on the passenger compartment is reduced through the deformation of the metal structure and the collapse of the energy-absorbing box.
The Anti-intrusion bar of the car door is specifically designed to prevent side impacts from invading the cockpit.
Term Clarification
In English, "Bumper" is called "Bumper", and "Anti-Collision beam" or "Anti-intrusion bar" is called "anti-collision beam" or" anti-intrusion bar". In China, the two are often confused.
The "anti-collision beam" at the rear of the truck is actually a device to prevent cars from getting stuck under the cargo, and its function is different from that of the anti-collision beam for passenger cars.
Other Notes
Not all vehicles are equipped with anti-collision beams, especially in low-cost models where they may be absent.
The replacement cost of the bumper is relatively low, while the damage to the anti-collision beam requires professional maintenance.
Youdaoplaceholder0 To sum up : They work together but have clear divisions of labor - the bumper is the "first line of defense" and the bumper is the "last barrier". In modern automotive safety design, only by combining the two can vehicles, pedestrians and occupants be comprehensively protected.
