The invention relates to an integrated side wall inner plate double-door-ring structure, a forming process and a vehicle. The integrated side wall inner plate double-door-ring structure comprises a second frame structure defined by an A stand column upper inner plate, an A stand column lower inner plate, a threshold inner plate, a C stand column inner plate, a top cover edge beam and a B stand column inner plate, and the double-door-ring structure is formed through integrated hot stamping; according to the integrally-formed side wall inner plate double-door-ring structure, distribution of plate materials is optimized, the integration degree of parts is effectively improved, molds needed for production of all single pieces and tool clamps needed for welding procedures are reduced, the cost of the tool clamps is saved, the production procedures are reduced, the production cost is reduced, and the production efficiency is improved. And the light weight effect and the collision performance of the whole vehicle are effectively improved.

    本发明涉及一种一体式侧围内板双门环结构、成型工艺及车辆,一体式侧围内板双门环结构包括:A立柱上内板、A立柱下内板、门槛内板、C立柱内板、顶盖边梁和B立柱内板围合形成的第二框架结构并一体式热冲压形成双门环结构,本申请示出一种一体式成型的侧围内板双门环结构,优化了板料的分布,有效提高了零件的集成度、减少了各单件生产所需要用到的模具和焊接工序所需要的工装夹具,节省了工装夹具成本、减少了生产工序、降低了生产成本,以及有效提高了整车轻量化效果及碰撞性能。
