Abstract

The invention discloses a front longitudinal beam connecting assembly and an electric vehicle. The front longitudinal beam connecting assembly includes a cowl lower beam, an engine compartment longitudinal beam assembly, two connecting beams and two door sill front longitudinal beams. The engine cabin longitudinal beam assembly includes two Two engine room longitudinal beams, the rear end of the engine room longitudinal beam is fixedly installed on the cowl lower beam, and the two connecting beams are respectively set corresponding to the two engine room longitudinal beams, and each connecting beam includes along the first connecting section and connecting with the first One end of the first connecting section is fixedly installed on the side end of the corresponding cabin longitudinal beam, the two threshold front longitudinal beams are respectively set corresponding to the two connecting beams, and one end of each threshold front longitudinal beam is fixedly installed At the corresponding end of the cowl lower beam, the other end of each door sill front longitudinal beam is fixedly installed on the end of the corresponding connecting beam. The cowl lower beam, the two cabin longitudinal beams and the two connecting beams respectively form two In this way, the impact force of the longitudinal beam of the spontaneous cabin is transmitted to the two frame structures, thereby reducing the impact on the battery.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a front longitudinal beam connecting assembly and an electric automobile. Background technique [0002] With the gradual increase of the battery space of electric vehicles, the design space of the force transmission beam of the vehicle body is continuously compressed, which makes the safety and weight design of the vehicle body more difficult. The hinge point area of ​​the rear section of the existing steel engine room longitudinal beam is formed by lap joint welding of multiple stamped steel parts such as the rear section connecting plate of the engine cabin longitudinal beam and the sub-frame mounting plate, forming an energy collection In this area, the connecting plate at the rear section of the engine room longitudinal beam and the sub-frame mounting plate are respectively located on both sides of the engine room longitudinal beam. It is transmitted to the door si...
