Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] It should be noted that if there is a directional indication in the embodiment of the present invention, the directional indication is only used to explain the relative positional relationship and movement conditions between the components in a specific posture. If the specific posture changes , then the directional indication changes accordingly.

[0037] In addition, if there are descriptions involving "first", "second" and so on in the embod...

Abstract

The invention discloses a front longitudinal beam connecting component and an electric vehicle. The front longitudinal beam connecting component comprises a front wall lower cross beam, an engine compartment longitudinal beam assembly, two connecting beams and two doorsill front longitudinal beams, the engine compartment longitudinal beam assembly comprises two engine compartment longitudinal beams, the rear ends of the engine compartment longitudinal beams are fixedly installed on the front wall lower cross beam, the two connecting beams are arranged corresponding to the two engine compartment longitudinal beams respectively, each connecting beam comprises a first connecting section and a second connecting section connected with the first connecting section, one end of each first connecting section is fixedly installed at the side end of the corresponding engine compartment longitudinal beam, and the two doorsill front longitudinal beams are arranged corresponding to the two connecting beams respectively. One end of each doorsill front longitudinal beam is fixedly installed at the corresponding end of the front wall lower cross beam, the other end of each doorsill front longitudinal beam is fixedly installed at the end of the corresponding connecting beam, and the front wall lower cross beam, the two engine compartment longitudinal beams and the two connecting beams correspondingly form two frame body structures respectively. Therefore, the impact force of the spontaneous cabin longitudinal beam is transmitted to the two frame body structures, so that the impact on the battery is reduced.

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...
