The invention discloses a hydrogen energy automobile body connecting structure. An upper automobile body doorsill of anautomobile body is a profile, a lower automobile body longitudinal beam rear section of the automobile body is a casting, and the upper automobile body doorsill and the lower automobile body longitudinal beam rear section are connected in a bolt fastening mode, a structural adhesive connection mode and an aluminum MIG welding mode. According to the hydrogen energy automobile body connecting structure, what is guaranteed is that the requirement for better collision strength is met, and compared with an FDS technology capable of achieving connection of a casting and a profile beam, the cost of the connecting technology in a bolt fastening mode, a structural adhesive connection mode and an aluminum MIG welding mode is far lower.

    本发明公开了一种氢能汽车车身连接结构。本发明的车身的上车体门槛为型材,车身的下车体纵梁后段为铸件,上车体门槛与下车体纵梁后段的连接采用螺栓紧固、结构胶连接和铝MIG焊方式连接。本发明的一种氢能汽车车身连接结构保证满足更好的碰撞强度的要求,相比可同样实现铸件与型材梁连接的FDS工艺,本发明采用螺栓紧固、结构胶连接和铝MIG焊方式连接工艺成本远远更低。
