The invention relates to a vehicle body structure which comprises left and right side wall inner plates, left and right side wall outer plate reinforcing plates, a cabin framework, left and right front wheel covers, a front wall plate, a rear floor framework and left and right rear wheel covers. The manufacturing method comprises the steps that blanking pieces of the left and right side wall inner plates, the left and right side wall outer plate reinforcing plates, the cabin framework, the left and right front wheel covers, the front wall plate, the rear floor framework and the left and right rear wheel covers are spliced into an integrated plate body, then hot stamping forming is conducted on the integrated plate body, and finally the integrated plate body is connected to form the vehicle body structure. The invention further provides an automobile. According to the scheme, traditional multi-part multi-procedure multi-welding-spot welding is changed into welding of several simple thermal forming parts which are integrally formed, and the matching quality problem caused by part size errors is avoided; the collision performance difference caused by the state consistency difference of multiple parts is avoided; the number of welding spots is reduced, so that the welding spot failure probability is reduced, the collision stability is improved, and the whole vehicle safety is improved.
本发明涉及一种车身结构,包括左右侧围内板、左右侧围外板加强板、机舱骨架、左右前轮罩、前围板、后地板骨架和左右后轮罩。一种制造方法包括分布将左右侧围内板、左右侧围外板加强板、机舱骨架、左右前轮罩、前围板、后地板骨架和左右后轮罩的落料片拼接为一体式板体,再将分别进行热冲压成型,最后将其连接形成车身结构。还提供一种汽车。本发明方案将传统的多零件多工序多焊点焊接而成更改为简单的几个一体成型的热成型零件焊接而成,避免了因零件尺寸误差,造成的匹配质量问题;避免了因多零件状态一致性差异,造成的碰撞性能差异;减少了焊点数量,从而减少焊点失效概率,进而提升碰撞稳定性,提升整车安全。
