Technical Field
[0001] This utility model relates to the field of front bumper beam technology, and in particular to a front bumper beam connection structure and a front bumper beam. Background Technology
[0002] The front bumper beam is an important protective structure at the front of a car. It is usually made of high-strength metal materials, such as steel and aluminum alloy. The front bumper beam is installed at the front of the vehicle, behind the bumper. The main function of the front bumper beam is to absorb the impact force first in the event of a frontal collision. Through its own deformation and energy absorption, it effectively disperses and reduces the transmission of collision energy to the vehicle body, thereby protecting important components such as the engine compartment and radiator, as well as the safety of the occupants. A high-quality front bumper beam can significantly improve the collision safety of a vehicle.
[0003] The back of the front bumper beam is usually equipped with symmetrical energy-absorbing boxes. The common connection method between the two is CO2 welding. In actual collision scenarios, the direction and position of the impact force on the front bumper beam are uncertain. When subjected to an offset collision, the above connection method prevents the energy-absorbing boxes from effectively absorbing energy and deforming. This results in the energy-absorbing boxes not being able to fully play their buffering role, and more of the collision energy may be transferred to the vehicle body, threatening the safety of the vehicle and its occupants. Therefore, a front bumper beam connection mechanism and a front bumper beam are needed to solve the above problems. Utility Model Content
