The invention discloses a lower vehicle body structure of a hydrogen fuel cell vehicle, and relates to the technical field of hydrogen energy vehicles. The lower vehicle body structure comprises a lower vehicle body and a hydrogen cylinder frame, an vehicle body cross beam is installed in the lower vehicle body, a seat cross beam is fixed above the vehicle body cross beam, and a lower vehicle bodymiddle channel is arranged on the upper sides of the vehicle body cross beam and the seat cross beam; and a mounting cavity is formed in the lower side of the interior of the lower vehicle body and located below the vehicle body cross beam, the hydrogen cylinder frame is mounted in the mounting cavity, and a buffer gasket is fixed to the upper side of the hydrogen cylinder frame. The structure has the beneficial effects that the hydrogen cylinder fixing cross beam of the structure, the vehicle body cross beam and the seat cross beam at the bottom of the vehicle body are fixed through bolts after being overlapped and combined, the rigidity of the lower vehicle body is improved, and the hydrogen cylinder fixing cross beam and the vehicle body cross beam are fixedly connected together through the connecting bolts and can jointly resist side impact; the safety of side collision is greatly improved. Meanwhile, the hydrogen cylinder is well protected.

    本发明公开了一种氢燃料电池汽车的下车身结构,涉及氢能汽车技术领域,包括下车身和氢瓶框架,所述下车身的内部安装有车身横梁,且车身横梁的上方固定有座椅横梁,所述车身横梁和座椅横梁的上侧设置有下车身中通道,所述下车身的内部下侧设置有安装腔,且安装腔位于车身横梁的下方,所述氢瓶框架安装于安装腔的内部,且氢瓶框架的上侧固定有缓冲垫片。本发明的有益效果是:该结构的氢瓶固定横梁与车身底部的车身横梁、座椅横梁叠加组合后通过螺栓固定,增加了下部车身的刚性,并且氢瓶固定横梁与车身横梁之间通过连接螺栓固定连接在一起,能够共同抵抗侧碰冲击,大幅提升了侧碰的安全性,同时对氢瓶也起到了很好的保护作用。
