The invention discloses a longitudinal beam front end structure which comprises a front wall lower cross beam, a longitudinal beam, a first reinforcing piece and a connecting supporting assembly. The front wall lower cross beam is connected with a first reinforcing piece, the longitudinal beam is connected with the first reinforcing piece through a connecting supporting assembly, the longitudinal beam is connected with the front wall lower cross beam, and the first reinforcing piece can reinforce and support the connecting supporting assembly. The front wall lower cross beam has the beneficial effects that the supporting pieces are connected with the side connecting pieces and the longitudinal beams correspondingly, the side connecting pieces are connected with the first reinforcing pieces, so that the longitudinal beams and the front wall lower cross beam are connected together, the front wall lower cross beam is connected with a plurality of structures, force dispersion is carried out, the stress concentration condition can be avoided, overall stress can be carried out, and the service life of the front wall lower cross beam is prolonged. And fatigue cracking is avoided.

    本发明公开了一种纵梁前端结构,包括前围下横梁、纵梁、第一加强件,以及连接支撑组件;前围下横梁上连接第一加强件,纵梁通过连接支撑组件与第一加强件连接,纵梁与前围下横梁连接,第一加强件可对连接支撑组件进行加固支撑。本发明的有益效果为支撑件分别与侧连接件和纵梁进行连接,通过侧连接件与第一加强件进行连接,从而使纵梁和前围下横梁连接在一起,通过前围下横梁和多个结构进行连接,进行力的分散,可以避免应力集中的情况,可以进行整体受力,避免疲劳开裂。
