The invention discloses an aluminum alloy passenger car stepping zone floor framework connecting structure. The aluminum alloy passenger car stepping zone floor framework connecting structure comprises a right side first transverse beam (1), a right side longitudinal beam (3), a right side enclosure vertical beam (16), a right side second transverse beam (2), a right side vertical beam (4), a left side first transverse beam (13), a left side longitudinal beam (12), a left side enclosure vertical beam (25), a left side second transverse beam (14), a left side vertical beam (15), a third middle transverse beam (9), a right side first inclined strut (5), a right side second inclined strut (8), a second middle transverse beam (7), a left side second inclined strut (10), a left side first inclined strut (11) and a floor first middle transverse beam (6). All beams are connected in a riveting way through pi-shaped joints (26), obtuse-angle joints (31), L-shaped joints (27) and T-shaped joints (28) respectively, so that an aluminum alloy framework is not deformed easily, the structural strength is high, and the overall structural rigidity of a stepping zone is enhanced.
