The invention particularly relates to an aluminum profile cross beam fixing structure for an automobile and the automobile, the fixing structure comprises an aluminum profile sleeve, a threaded through hole is formed in the aluminum profile sleeve in the vertical direction, the aluminum profile sleeve is placed in a cavity of an aluminum profile cross beam, and the threaded through hole is communicated with the threaded through hole. The threaded through hole of the aluminum profile sleeve and the bolt hole in the aluminum profile cross beam are located on the same straight line, and a plurality of positioning convex hulls formed by being extruded by a punch are arranged on the upper surface of the aluminum profile cross beam and located in the area around the aluminum profile sleeve; and positioning and connection of the aluminum profile cross beam and the aluminum profile sleeve are realized through the extruded extrusion deformation structure. The series of structures provided by the invention can meet the fixing requirements of aluminum profile cross beams with common sections in automobiles, and the cross beams, the sleeves and the convex point structures can be combined according to product structures and process conditions.
