The invention relates to the technical field of vehicle structures, in particular to an automobile A column and a vehicle. The automobile A pillar comprises an A pillar body, a first connecting piece and a second connecting piece, flange edges are arranged on the two sides of the cavity pipe fitting, and the cavity pipe fitting is welded to the A column body through the flange edges. By means of the arrangement, on one hand, the structural strength of the automobile A column is improved, during collision, collision impact is absorbed and buffered through the cavity pipe fitting, the possibility that the A column structure is seriously deformed due to collision is reduced, and the safety of people in an automobile is guaranteed. On the other hand, the sectional area of the automobile A column is reduced, the visual impairment angle of the automobile A column is reduced, and wide view of a driver during turning is guaranteed. The flange edge is arranged, so that the contact area of the welding position is increased, the welding tightness is guaranteed, the welding difficulty is reduced, the situation that the cavity pipe fitting falls off from the A column body due to the fact that the welding position cracks during impact is avoided, and the reliability of the automobile A column is improved.

    本发明涉及车辆结构的技术领域,更具体地说,本发明涉及一种汽车A柱及车辆。其中,所述汽车A柱包括:A柱本体;空腔管件,所述空腔管件的两侧设置有法兰边,所述空腔管件通过所述法兰边焊接于所述A柱本体。如此设置,一方面,提高了汽车A柱的结构强度,在碰撞时,碰撞的冲击通过空腔管件的吸和缓冲,减少了A柱结构受到撞击出现严重变形的可能性,保证车内人员的安全性。另一方面,减少汽车A柱的截面积,减少了汽车A柱的视觉障碍角,保证驾驶员转弯时视野开阔。设置法兰边增加了焊接处的接触面积,保证了焊接的紧固性,降低焊接难度,避免冲击时,焊接处开裂,导致空腔管件从A柱本体处脱落的情况发生,提高汽车A柱的可靠性。
