The invention provides an enhanced door ring structure, a processing method thereof and a vehicle, and the processing method of the enhanced door ring structure comprises the following steps: obtaining the strength requirements of each part of the enhanced door ring structure, selecting plates with different thicknesses for rolling and blanking, and respectively obtaining material sheets with different thicknesses of each part of the door ring structure, comprising a side wall upper edge beam material piece, a side wall B column upper material piece, a side wall B column lower hinge material piece, a side wall front doorsill material piece and a side wall A column hinge column material piece. The material sheets with the different thicknesses are sequentially placed on a workbench, supporting parts are arranged at the bottoms of the material sheets with the different thicknesses to adjust the height, and it is guaranteed that the opposite weld joint end faces of every two adjacent material sheets with the different thicknesses are aligned and then fixed; sequentially carrying out laser splicing to form an enhanced door ring structure blank; and the door ring structure blank is subjected to hot stamping to form the integrated enhanced door ring structure. Large-scale integration of the door ring structure is achieved, the number of parts and welding spots of the door ring structure are reduced, the overall manufacturing efficiency of the door ring structure is improved, and overall light weight is achieved.

    本公开提供了一种增强型门环结构及其加工方法和车辆,增强型门环结构的加工方法包括:获取增强型门环结构各个部位的强度需求,选用不同厚度的板料进行轧制及落料,分别得到门环结构各个部位的不等厚料片,包括侧围上边梁料片、侧围B柱上料片、侧围B柱下铰链料片、侧围前门槛料片以及侧围A柱铰链柱料片;将各个不等厚料片依次放在工作台上,在不等厚料片的底部设置支撑部调整高度,保证每相邻的两个不等厚料片相对的焊缝端面对接齐平后固定;依次激光拼接形成增强型门环结构胚料;对门环结构胚料热冲压形成一体式增强型门环结构。实现门环结构的大规模集成,减少门环结构的零部件数量和焊点,提升门环结构整体制造效率,实现整体轻量化。
