The invention relates to an automobile longitudinal beam structure which comprises an automobile longitudinal beam and a first reinforcing piece. The automobile longitudinal beam comprises a longitudinal beam bottom plate, a longitudinal beam upper side plate connected to the upper side of the longitudinal beam bottom plate and a longitudinal beam lower side plate connected to the lower side of the longitudinal beam bottom plate, a U-shaped beam-shaped structure is defined by the longitudinal beam bottom plate, the longitudinal beam upper side plate and the longitudinal beam lower side plate, and the automobile longitudinal beam is provided with a concave part used for avoiding automobile wheels. The upper side portion of the first reinforcing piece is connected with the longitudinal beam upper side plate, the lower side portion of the first reinforcing piece is connected with the longitudinal beam lower side plate, the front side portion and the rear side portion of the first reinforcing piece are respectively connected with the longitudinal beam bottom plate, and the first reinforcing piece is of a structure with the middle portion arched leftwards relative to the front side portion and the rear side portion on the whole. A closed cavity structure is defined by the first reinforcing piece and the automobile longitudinal beam and arranged at the sunken part. According to the automobile longitudinal beam structure, the collision performance of the automobile longitudinal beam structure can be improved, and adverse effects caused by the sunken parts arranged for avoiding automobile wheels can be relieved or even eliminated.

    本发明涉及一种汽车纵梁结构,包括汽车纵梁和第一加强件;汽车纵梁包括纵梁底板、连接在纵梁底板上侧的纵梁上侧板以及连接在纵梁底板下侧的纵梁下侧板,纵梁底板、纵梁上侧板和纵梁下侧板围成U型梁状结构,汽车纵梁上设置有用于避让汽车车轮的凹陷部;第一加强件的上侧部与纵梁上侧板连接,第一加强件的下侧部与纵梁下侧板连接,第一加强件的前侧部和后侧部分别与纵梁底板连接,第一加强件整体上为中部相对于前侧部和后侧部向左拱起的结构,第一加强件和汽车纵梁之间围成封闭腔体结构,封闭腔体结构设置在凹陷部处。本发明能够提升汽车纵梁结构的碰撞性能,能够减轻甚至消除因为避让汽车车轮而设置的凹陷部所带来的不利影响。
