Vehicle body structure and vehicle
By setting collision reinforcement components at the front end of the engine compartment longitudinal beams and combining them with outer panel reinforcement plates, energy absorption boxes, and embedded reinforcement components, the force transmission path and energy absorption effect of the front collision structure are optimized. This solves the problems of insufficient force transmission path and collision performance in existing technologies, achieves more efficient energy dispersion and absorption, and improves the vehicle's collision performance and occupant safety.

AI Technical Summary
Technical Problem
The force transmission path and collision performance of the existing front collision structure still need to be improved and are difficult to optimize effectively.
Method used
Collision reinforcements are installed at the front end of the longitudinal beams of the cabin to increase the cross-sectional area and form a force transmission path. Combined with the outer plate reinforcement, energy absorption box and embedded reinforcements, the force transmission path and energy absorption effect are optimized.
Benefits of technology
By enhancing the force transmission path and energy absorption effect, the impact force is reduced, the longitudinal beam deformation is decreased, vehicle damage is mitigated, and occupant safety is improved.
