In the event of a collision, the front bumper of the car can absorb some energy, reduce the impact on the body and passengers, and play a buffering role. Meanwhile, the crossbeam of the bumper can withstand impacts from the side, protecting other parts of the vehicle from damage. In addition, the appearance design of the bumper can also beautify the vehicle, improve the aerodynamic characteristics of the vehicle, reduce air resistance, and improve fuel efficiency.
