As a preferred technical scheme of the utility model: the multifunctional reinforcing rib 3 comprises a circular through hole 301, an annular through hole 302 and an arched metal plate 303, the arched metal plate 303 is integrally in an arched structure, the circular through hole 301 matched with the arched metal plate 303 is formed in the middle of the arched metal plate 303 and on the metal plates on the two sides of the arched metal plate 303, the annular through hole 302 matched with the arched metal plate 303 is formed in the two sides of the middle of the arched metal plate 303, the anti-seismic buffer plate 4 comprises an anti-seismic metal plate 401 and buffer pads 402, the two ends of the anti-seismic metal plate 401 are connected with the buffer pads 402 matched with the automobile front fender 1, the buffer pads 402 are matched with the cavity 102 of the automobile front fender 1, the two anti-fatigue spring devices 6 respectively comprise anti-fatigue springs 601 and spring pads 602, the two ends of the anti-fatigue springs 601 are respectively and fixedly connected with the spring pads 602 matched with each other, one spring pad 602 is fixedly connected with the buffer pad 402 of the anti-seismic buffer plate 4, the other spring pad 602 is fixedly connected with the cavity 102 of the automobile front fender 1, the anti-vibration buffer plate 4 is movably connected with the cavity 102 of the automobile front vane plate 1 through the adaptive anti-fatigue spring device 6, the multifunctional reinforcing ribs 3 and the anti-vibration buffer plate 4 are made of hard alloy steel, and the problems of noise, vibration and sound vibration roughness of the automobile are one of the problems concerned by all large automobile manufacturing enterprises and part enterprises in the international automobile industry. The reduction of the radiation power of the front clapboard and the vibration radiation noise of the front clapboard to the passenger compartment are one requirement of noise, vibration and sound vibration roughness, and the reasonable design of the reinforcing ribs can improve the performance value. In the design of the load-bearing beam such as a threshold beam, the maximum bending moment is reduced for improving the load-bearing capacity of the load-bearing beam, or the bending-resistant section modulus is improved by adopting a reasonable section shape. Therefore, the reinforcing ribs at the cavity part of the reinforcing beam cannot enable the main reinforcing section to be changed sharply, otherwise the performance is affected; the reinforcing ribs also should not be made smaller in cross section, which would affect the moment of inertia of the cross section. Therefore, the cavity formed by the inner plate of the doorsill and the side wall is required to be integrally consistent, and the reinforcing rib of the inner plate of the doorsill is required to face the inside of the vehicle but not the outside of the vehicle; in addition, when the axis of the rib is an arc, the rib is likely to be twisted during vibration, and if not necessary, the axis of the rib should be a straight line. Through reasonable design, the reinforcing rib can improve rigidity, and when the reinforcing rib is designed to be vertical to a force transmission path, the reinforcing rib also has the effect of accelerating deformation. For example, when an automobile collides, in order to absorb more impact energy, engineers design some crushing ribs at the front end of the longitudinal beam, so that when the longitudinal beam is impacted and extruded, the front end of the crossbeam can be guided by the crushing ribs to bulge and deform or to be folded and bent, the front end of the crossbeam is locally weakened, the distribution of the rigidity of the whole automobile meets the design principle and the energy absorption curve graph, and the collision requirement is finally met.
