Vehicle front body structure with crash can and bumper beam
The granted patent US12071175B2 describes a vehicle front body structure designed to enhance safety during collisions. The structure includes a front side frame on both the right and left sides of the vehicle, extending longitudinally, and a bumper beam positioned at the front of each frame. Each bumper beam features inclined sections at both ends that extend outward and rearward. Additionally, crash cans are integrated at the front end of each side frame, extending forward and outward, with their front ends connected to the bumper beam's inclined sections. A notable aspect of the design is the inclusion of vulnerable portions within the crash cans, which are specifically engineered to exhibit low strength when subjected to collision forces from the front of the vehicle.
Further claims detail the structural characteristics of the crash cans and front side frames. The cross-section of the rear end of each crash can is designed to match that of the front end of the corresponding side frame. Vulnerable portions are created through notches and ribs that strategically weaken certain areas to absorb impact energy. The patent also specifies the presence of outer and inner vulnerable portions on the front side frames, with the outer portion being stronger than the inner one. This design aims to optimize energy absorption during a collision, thereby enhancing passenger safety. The patent outlines various configurations and structural features, including irregular beads and notches, to achieve the desired balance between strength and vulnerability in the vehicle's front body structure.
