AI Technical Summary
Traditional single-metal automotive crossbeams cannot effectively absorb impact energy in high-speed collisions or severe side impacts, and their structural strength is insufficient to withstand extreme loads, resulting in severe damage to the vehicle body. Furthermore, the increased weight of the crossbeams affects the vehicle's fuel efficiency and handling performance.
The system employs a front crossbeam, a rear crossbeam, welded reinforcing hoops, and various other reinforcement structures. The overall structure of the crossbeam is enhanced through bolted connections and welding, including the combined use of a top reinforcing seat, an inner reinforcing plate, and welded reinforcing hoops, to improve the overall performance and robustness of the crossbeam.
It improves the energy absorption capacity of the vehicle's crossbeams during a collision, reduces vehicle body damage, maintains the vehicle's lightweight design and handling performance, and enhances passenger safety.

TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile production, and concretely relates to a reinforcing structure of automobile cross beam. BACKGROUND
[0002] As an indispensable important component in modern automobile body structure, the automobile cross beam plays multiple key roles. It not only is a solid cornerstone supporting the weight of the entire vehicle body, ensuring the stability and reliability of the vehicle during driving, but also plays a crucial role when the vehicle unfortunately encounters a collision accident. In the instant of collision, the automobile cross beam, like a brave guardian, responds quickly, effectively absorbs and disperses the impact force from the outside by using its tough material and carefully designed structure. This process not only reduces the damage to the vehicle body structure, but more importantly, it greatly reduces the impact on the passenger compartment, providing valuable survival space and buffer time for passengers inside the vehicle, thereby effectively protecting the lives of passengers.
[0003] Traditional automobile cross beams usually adopt a single metal material, such as high-strength steel. This design can meet the basic safety and strength requirements to some extent, but has the following defects: a single metal material cross beam cannot effectively absorb impact energy in high-speed collisions or severe side impacts, and the structural strength is difficult to withstand extreme loads, resulting in serious damage to the vehicle body and reducing safety. In order to improve the structural strength, the single metal material cross beam often needs to be thickened or use higher strength material, resulting in an increase in the weight of the cross beam, which damages the fuel efficiency and handling performance of the vehicle.
