Embodiment Construction

[0027] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] see Figure 1-Figure 6 , the present invention is a rear section structure of the front longitudinal beam of an electric vehicle, which is an aluminum die-casting molded part as a whole. The rear section structure 3 of the front side beam includes the front matching connection section 4 connected with the front side beam 1, the downward energy-absorbing middle section 5 located in the middle, and the rear matching connection section connected with the door sill side beam 2 arranged in sequence along the vehicle body direction. 6. The rear section structure 3 of the front longitudinal beam has a small front part and a large rear part in the shape of a trumpet, and both sides of the rear section structure 3 of the front longitudinal beam are provided with upward flanges 7, and the downward energy-absorbing middle section 5...

Abstract

The invention relates to a pure electric automobile part, in particular to a front longitudinal beam back segment structure for an electric automobile. The front longitudinal beam back segment structure comprises a front fit connecting segment connected with a front longitudinal beam, a downward energy absorption middle segment positioned on the middle part, and a back fitting connecting segment connected with a doorsill longitudinal beam in sequence along an automobile body, wherein the whole front longitudinal beam back segment structure is flared with the front part being smaller and the back part being larger; both sides of the front longitudinal beam back segment structure are provided with upward flanges; a plurality of longitudinal reinforcing plates and at least one transverse reinforcing plate are arranged on the inner side of the downward energy absorption middle segment; reinforcing posts are arranged at intervals on the longitudinal reinforcing plates; the longitudinal reinforcing plates and the transverse reinforcing plate are connected crossly; reinforcing posts are arranged on the joints of intersections. By adopting the front longitudinal beam back segment structure, the problem of difficulty in connecting a front longitudinal beam sunken region with the doorsill longitudinal beam is solved, and all-aluminum light design of the longitudinal beams of an automobile body is realized conveniently.

Description

technical field [0001] The invention relates to a pure electric vehicle component, in particular to a rear section structure of the front longitudinal beam of the electric vehicle. Background technique [0002] In recent years, in response to national policies, the state and automobile factories are vigorously developing pure electric vehicles. For electric vehicles, in order to increase the cruising range of electric vehicles on the basis of the original power, one of the important solutions is the lightweight design of the car body. The invention introduces the application of a new beam of aluminum alloy material. Because the density of aluminum is one-third of that of iron, the use of aluminum alloy materials can greatly reduce its mass. The structural design of this new type of beam greatly reduces its mass by using new materials, and can meet the requirements of vehicle crash performance. [0003] As car consumers become more mature and rational, car safety performan...
