AI Technical Summary
In the vehicle front bulkhead structure, it is impossible to simultaneously achieve excellent pedestrian protection capabilities and front bulkhead stiffness under pressure, and there are noise, vibration and harshness (NVH) problems as well as pedestrian injury risks due to the enclosed parts.
Design a front bulkhead assembly including an inner upper cover plate, an inner lower cover plate, a transverse upper component of the front bulkhead, and a side reinforcing component of the front bulkhead. By forming an open portion in the upper part of the front bulkhead cover plate and forming a π-shaped structure between the lower part and the shock absorber housing, the connection stiffness and NVH performance are enhanced.
It improves pedestrian protection capabilities, enhances the rigidity of the front bulkhead, reduces NVH issues, decreases the risk of pedestrian injury, reduces cost and weight, and improves the torsional rigidity of the vehicle body.
