The invention discloses a Vehicle body front bottom plate cross beam and bottom plate longitudinal beam cross-shaped structure. The structure comprises a front bottom plate cross beam, a front bottomplate cross beam joint, a rear bottom plate cross beam, a rear bottom plate cross beam joint and a longitudinal beam; the structure further comprises a front bottom plate cross beam connecting beam, arear bottom plate cross beam outer joint, a threshold beam and a threshold pedal; the front bottom plate cross beam connecting beam is arranged below the front bottom plate cross beam; the front bottom plate cross beam connecting beam is welded with the front bottom plate cross beam, the front bottom plate cross beam joint and the longitudinal beam; the rear bottom plate cross beam outer joint iswelded with the longitudinal beam; the front end of the threshold beam is welded with the end part of the front bottom plate beam connecting beam; the rear end of the threshold beam is welded with the rear bottom plate cross beam outer joint; the threshold pedal is welded with the lower end of the longitudinal beam, the lower end of the front bottom plate cross beam connecting beam and the lowerend of the threshold beam; the front bottom plate cross beam connecting beam stretches across the longitudinal beam to form a stable and reliable cross-shaped structure, so that when front collision and side collision happen, collision force can be transmitted laterally and forwardly, and the problem of collision safety risks of an original single longitudinal beam structure is solved.
本发明公开了一种车身前底板横梁与底板纵梁十字型结构,包括前底板横梁、前底板横梁接头、后底板横梁、后底板横梁接头和纵梁,还包括前底板横梁连接梁、后底板横梁外接头、门槛梁和门槛踏板,前底板横梁连接梁设于前底板横梁下方,前底板横梁连接梁分别与前底板横梁、前底板横梁接头和纵梁焊接,后底板横梁外接头与纵梁焊接,门槛梁前端与前底板横梁连接梁端部焊接,门槛梁后端与后底板横梁外接头焊接,门槛踏板分别与纵梁下端、前底板横梁连接梁下端、门槛梁下端焊接,通过前底板横梁连接梁横跨纵梁构成稳定可靠的十字型结构,从而实现在正面碰撞和侧面碰撞发生时,碰撞力能够进行侧向和正向传递,解决原先单一纵梁结构碰撞安全风险问题。
