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.

    本发明涉及一种侧围外板双门环加强结构,包括侧围外板双门环总成,侧围外板双门环总成以具有两个封闭门环的一体式板体热冲压而成;侧围外板双门环总成包括A柱部、B柱部、C柱部、门槛部、第一上边梁部和第二上边梁部;A柱部、第一上边梁部、B柱部和门槛部形成第一封闭门环,C柱部、第二上边梁部、B柱部、门槛部形成第二封闭门环。一种制造方法包括将各个落料片拼接为一体式板体,再热冲压成型。一种侧围外板加强总成包括侧围外板双门环加强结构。本发明方案将料片板件整体集成后,再一体热冲压形成具有前后门环的侧围外板双门环加强结构,部件之间的连续性、整体性更高,强度和刚度更好;无焊接缺陷和焊接失效等隐患;无焊点搭接,可实现侧围外板减重。
