The invention discloses an under-floor structure of a plug-in hybrid vehicle and an extended-range vehicle, and relates to the technical field of vehicle floors, the under-floor structure comprises a single longitudinal beam, an exhaust pre-silencer, a fuel tank and a power battery, and a necessary exhaust pipeline is arranged on the side face of the power battery in the width direction; in the longitudinal direction, an exhaust pipeline, a cooling pipeline and high-low voltage wiring harnesses are arranged in front of the power battery, and other space is released to the power battery for use, so that the width of the battery is not limited by the transverse distance of the longitudinal arm hinges on the two sides, and the size maximization of the power battery is realized; on the premise that the safety performance of the whole vehicle is not reduced, the lower vehicle body of the single-longitudinal-beam structure is constructed, the defects that due to the design of a lower vehicle body of a double-longitudinal-beam structure, the weight and cost are increased are overcome, the problem that a power battery installation structure corresponding to the lower vehicle body without the longitudinal beam structure is prone to cracking is solved, the dynamic property and economical efficiency of the whole vehicle are improved, and the product competitiveness is greatly improved.
本发明公开了一种插电混动汽车和增程式汽车的地板下结构,涉及车辆地板技术领域,它包括:单纵梁、排气前消声器、燃油箱、动力电池,在宽度方向上,动力电池侧面设置必要的排气管路;在纵向方向上,动力电池前面布置排气管路及冷却管路和高低压电线束,其他空间也释放给动力电池使用,使电池宽度不受两侧纵臂铰链横向距离限制,实现动力电池尺寸最大化;在整车安全性能不降低前提下,构建单纵梁结构下车身,解决了双纵梁结构下车身过设计导致重量和成本增加弊端、无纵梁结构下车身对应的动力电池安装结构易发生开裂的问题,提升了整车的动力性和经济性,大幅提升产品竞争力。
