The invention discloses a high-strength automobile floor longitudinal beam which comprises a longitudinal beam body, a main shell arranged in the middle of the longitudinal beam body, a buffer piece,a flanging, reinforcing rib plates, reinforcing ribs, first reinforcing convex rings, and second reinforcing convex rings. First mounting holes are formed in the inner walls of the two sides of the main shell, and a second mounting hole is formed between every two adjacent first mounting holes. The buffer piece is arranged in the main shell; the flanging is arranged on the outer side of the upperend of the main shell, mounting plates are arranged at the two ends of the flanging, and third mounting holes are formed in the mounting plates; the reinforcing rib plates are arranged at the includedangles between the mounting plates and the flanging; the reinforcing ribs are arranged at the bottom end of the interior of the main shell; the first reinforcing convex rings are arranged at the twoends of the first mounting holes; and the second reinforcing convex rings are arranged at the two ends of the second mounting holes. The automobile floor longitudinal beam is high in structural strength and not prone to damage due to stress in the collision process, and the driving safety is improved.
