<p>A vehicle frame component for a framework structure of a passenger car relates to the vehicle manufacturing field. The vehicle frame component comprises a square bottom plate and a groove on the bottom plate. A square hollow tubular structure is consisted of the bottom plate and the groove. Rivet holes (110) are respectively provided on a first flange (105) and a second flange (106) of the bottom plate far away from the hollow tubular structure. The vehicle frame component is made of aluminum alloy or magnesium alloy material. According to the needs of use, a supporting rib (109) can be provided in the hollow tubular structure or the sides of the square hollow tubular structure far away from the bottom plate are provided with flanges (107, 108) which parallel to the bottom plate. The junction of the supporting rib (109) and the bottom plate and the junction of the supporting rib (109) and the sides far away from the bottom plate can use Y-shaped connecting structure, so as to reinforce the impact and bending resistances of the vehicle frame component. The junctions of the bottom plate and the groove, the junctions of the groove and the flanges thereon and the other corners all use a round angle design, so as to prevent cracks caused by the local excessive stress concentration.</p> |
