The invention relates to a side wall outer plate double-door-ring reinforcing structure which comprises a side wall outer plate double-door-ring assembly, and the side wall outer plate double-door-ring assembly is formed by an integrated plate body with two closed door rings in a hot stamping mode. The side wall outer plate double-door-ring assembly comprises an A column part, a B column part, a C column part, a doorsill part, a first upper edge beam part and a second upper edge beam part. The A-pillar part, the first upper edge beam part, the B-pillar part and the doorsill part form a first closed door ring, and the C-pillar part, the second upper edge beam part, the B-pillar part and the doorsill part form a second closed door ring. The manufacturing method comprises the steps that all the blanking pieces are spliced into an integrated plate body, and then hot stamping forming is conducted. The side wall outer plate reinforcing assembly comprises the side wall outer plate double-door-ring reinforcing structure. According to the scheme, after the material sheet plates are integrally integrated, the side wall outer plate double-door-ring reinforcing structure with the front door ring and the rear door ring is formed through integral hot stamping, the continuity and the integrity between the parts are higher, and the strength and the rigidity are better; hidden dangers such as welding defects and welding failures are avoided; welding spot lap joint is avoided, and the weight of the side wall outer plate can be reduced.
