The invention discloses a front longitudinal beam for a vehicle and the vehicle with the front longitudinal beam. The front longitudinal beam comprises a longitudinal beam front section and a longitudinal beam middle section, the longitudinal beam middle section is located behind the longitudinal beam front section and connected with the longitudinal beam front section, the longitudinal beam middle section comprises a longitudinal beam outer plate and a longitudinal beam inner plate, the longitudinal beam outer plate is located on the side, facing the outside of a vehicle, of the longitudinal beam inner plate, and the longitudinal beam outer plate is connected with the longitudinal beam inner plate. The longitudinal beam inner plate is provided with an inner plate concave part which is concave towards the outside of the vehicle at a first position, the longitudinal beam outer plate is provided with an outer plate concave part which is concave towards the inside of the vehicle at a second position, and the second position is located behind the first position. According to the front longitudinal beam disclosed by the invention, the inner plate concave part and the outer plate concave part are arranged on the longitudinal beam middle section, so that the longitudinal beam middle section can be bent and deformed at the inner plate concave part and the outer plate concave part to absorb energy when transmitting force backwards, and the collision performance of a vehicle is favorably improved.
本发明公开了一种用于车辆的前纵梁及具有其的车辆。该前纵梁包括:纵梁前段和纵梁中段,纵梁中段位于纵梁前段的后方且与纵梁前段相连接,纵梁中段包括纵梁外板和纵梁内板,纵梁外板位于纵梁内板的朝向车外的一侧,且纵梁外板与纵梁内板相连接,纵梁内板具有在第一位置处向车外方向凹陷的内板凹陷部,纵梁外板具有在第二位置处向车内方向凹陷的外板凹陷部,第二位置位于第一位置的后方。根据本发明的前纵梁,通过在纵梁中段上设置内板凹陷部和外板凹陷部,使得纵梁中段在向后传力时能够在内板凹陷部和外板凹陷部处折弯变形吸能,有利于提升车辆的碰撞性能。
