发动机舱前纵梁后段结构
摘要：
本实用新型提出了一种发动机舱前纵梁后段结构，其包括：从上至下依次叠置并连接在一起的发动机舱前地板、前纵梁后段上加强板以及前纵梁后段板，所述前纵梁后段上加强板分别和所述发动机舱前地板、所述前纵梁后段板形成空腔结构。本实用新型通过使所述前纵梁后段上加强板分别和所述发动机舱前地板、所述前纵梁后段板形成空腔结构，来增加发动机舱前纵梁后段结构的刚度和强度，从而大大提高发动机舱的正面碰撞和偏置碰撞的性能。
摘要（英）：

The utility model provides an engine compartment front longitudinal beam rear segment structure which comprises an engine compartment front floor, a front longitudinal beam rear segment upper strengthening plate and a front longitudinal beam rear segment plate, wherein the engine compartment front floor, the front longitudinal beam rear segment upper strengthening plate and the front longitudinal beam rear segment plate are sequentially stacked from top to bottom and connected together. A cavity structure is formed by the front longitudinal beam rear segment upper strengthening plate and the engine compartment front floor. A cavity structure is formed by the front longitudinal beam rear segment upper strengthening plate and the front longitudinal beam rear segment plate. According to the engine compartment front longitudinal beam rear segment structure, due to the fact that the cavity structure is formed by the front longitudinal beam rear segment upper strengthening plate and the engine compartment front floor and the cavity structure is formed by the front longitudinal beam rear segment upper strengthening plate and the front longitudinal beam rear segment plate, the rigidity and the strength of the engine compartment front longitudinal beam rear segment structure are improved, and the performance of head-on collision and the performance of offset collision of an engine compartment are greatly improved.
