Abstract: A front cabin frame assembly includes a front beam front section, an upper side beam, a cowl reinforcement crossbeam, a cowl outer reinforcement and an A-pillar. A front end of the front beam front section is laterally connected with a front end of the upper side beam. A root portion of the front beam front section is connected with the cowl reinforcement crossbeam. A root portion of the upper side beam is connected with the A-pillar. The cowl outer reinforcement is connected with the root portion of the front beam front section and the A-pillar. The front cabin frame assembly could effectively absorb the head-on collision energy and has reasonable load transfer paths, which improves the flexural and torsion stiffness, the collision safety and NVH performance of the entire vehicle.

Abstract: A vehicle engine compartment assembly includes an upper longitudinal beam and a front subframe disposed under the upper longitudinal beam. The vehicle engine compartment assembly further includes a middle longitudinal beam and a connecting supporting member. The middle longitudinal beam is disposed between the upper longitudinal beam and the front subframe. The connecting supporting member is connected to each of the middle longitudinal beam, the upper longitudinal beam and the front subframe. In the vehicle engine compartment assembly, the middle longitudinal beam is added between the upper longitudinal beam and the front subframe, and the upper longitudinal beam, the middle longitudinal beam and the front subframe are connected together to form a stable structure having a shape of “”. When the vehicle suffers collision at a high speed, the impact force is transferred through three load transfer paths to improve the energy absorption effect.
