The invention provides a stiffening beam structure, and relates to a device having a shock absorption function for motor vehicles. The stiffening beam structure comprises a bent stiffening beam front segment with a front end convex table, a first ladder convex table, a concave table and convex closure, and a curved stiffening beam rear segment with a second ladder convex table and a rear end convex table, and can enable an electrophoresis liquid to sufficiently flow in so as to effectively prevent corroding and rusting; according to the stiffening beam structure, the upper top surface of the front end convex table, the upper top surface of the first ladder convex table and the upper surface of the concave table are respectively in contact with the inner top surface of a front longitudinal beam or a rear longitudinal beam groove, the upper top surface of the convex closure is in contact with the inside surface of the front longitudinal beam or the rear longitudinal beam groove, and the upper top surface of the second ladder convex table and the upper top surface of the rear end convex table are respectively in contact with the inner top surface of the front longitudinal beam or the rear longitudinal beam groove. According to the stiffening beam structure disclosed by the invention, the number of abutted surfaces of the stiffening beam is reduced, so that workers can conveniently weld spots, the working time is shortened, and besides, the abnormal noise of the bodies of the motor vehicles is reduced; sections are additionally arranged, the distortion and the bending rigidity of the body of each motor vehicle are also improved, and the structural rigidity of a stiffening beam is also enhanced.
