The invention discloses a vehicle body door ring structure and a vehicle. The technical problem that in the prior art, an A column and a roof side rail are prone to being bent is solved. The vehicle body door ring structure comprises a door ring body and a first pipe beam, the door ring body comprises an upper edge beam, a lower edge beam and at least two stand columns, the at least two stand columns are distributed in the length direction of a vehicle body at intervals, and the two ends of the stand columns are connected with the upper edge beam and the lower edge beam correspondingly to define an annular structure; the cavity extends from the first stand column to the last stand column in the axial direction of the upper edge beam. The first tubular beam is located in the cavity and connected with the upper edge beam and each stand column. The first tubular beam is arranged in an original cavity of the roof side rail of the door ring body, and the strength of the door ring body and the roof side rail is effectively improved under the condition that the size of the cavity of the roof side rail is not increased. The first pipe beam is connected with the upper edge beam and each stand column, so that the bending resistance of the door ring in an A column area can be improved, the impact of direct collision or rolling of a vehicle is effectively resisted, and the safety of a passenger compartment is protected.
本申请公开了一种车身门环结构及车辆,解决现有技术A柱与上边梁容易弯折的技术问题。车身门环结构包括门环本体和第一管梁,门环本体包括上边梁、下边梁以及至少两根立柱,至少两根立柱沿车身长度方向间隔分布,且立柱的两端分别连接上边梁和下边梁以围成环状结构,上边梁设有腔体,腔体沿着上边梁的轴向由第一根立柱至最后一个立柱延伸;第一管梁位于腔体且与上边梁以及每根立柱均连接。第一管梁布置在门环本体的上边梁的原有腔体内部,在不增大上边梁腔体大小的情况下有效提高门环本体和上边梁的强度。第一管梁与上边梁和每根立柱均连接,可以提高门环在A柱区域的抗弯折能力,有效抵抗车辆发生正碰或者翻滚时的冲击,保护乘客舱的安全性。
