What is the function of the foam in front of the anti-collision beam?

The functions are: first, as a cushioning foam for collision protection, and second, to support the front bumper. The following is a related introduction to the anti-collision beam: 1. Definition: The two ends of the anti-collision beam are connected to low-speed energy absorption boxes with very low yield strength, which are then bolted to the vehicle's longitudinal beams. The low-speed energy absorption boxes can effectively absorb collision energy during low-speed impacts, minimizing damage to the vehicle's longitudinal beams, thereby fulfilling their protective role. 2. Structure: The anti-collision beam structure should ensure that the low-speed energy absorption boxes effectively absorb energy during low-speed impacts through deformation. The anti-collision beam is bolted to the vehicle body for easy removal and replacement.
The foam in front of the anti-collision beam isn't just for decoration—I believe it's a crucial part of the safety design. In low-speed collisions, such as accidentally scraping against a pole or another car while parking, the foam acts like a cushion to absorb the impact, preventing the steel beam from directly bearing the force and deforming or breaking. This helps protect the entire vehicle structure. More importantly, it also enhances pedestrian safety. If a collision with a pedestrian occurs, the foam softens the contact point, reducing the risk of leg injuries and preventing fractures. While researching car safety, I've noticed that many new vehicles incorporate this design because foam materials are low-cost and easy to replace. After an accident, only the foam needs to be replaced rather than expensive components, saving both time and money. The foam is typically made of plastic or specific foam materials—lightweight and durable—capable of performing effectively in multiple minor accidents. In short, it's a hidden protective feature that enhances overall driving safety.
