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.
