The invention provides an automobile B-pillar upper lap joint structure and an automobile. The lap joint structure comprises a B-pillar reinforcing plate and an A-pillar upper reinforcing plate, one side of the B-pillar reinforcing plate protrudes to form a protruding part, and the A-pillar upper reinforcing plate is of a flat plate structure; the A-pillar upper reinforcing plate covers the concave opening surface of the other side of the whole B-pillar upper reinforcing plate to form a closed annular structure; and the A-pillar upper reinforcing plate is also welded and fixed to the B-pillarupper reinforcing plate. According to the scheme, a vehicle collision force transmission path is smooth, the bending risk of a pillar A is avoided, connection is enhanced, the torsional rigidity of abody in white is remarkably improved, the abnormal sound risk is eliminated, and the safety quality and the sensory quality of a vehicle are synchronously improved.

    本发明提供一种汽车B柱上部搭接结构及汽车,搭接结构包括B柱加强板和A柱上加强板,B柱加强板一侧凸出形成有凸出部,A柱上加强板为平板结构;A柱上加强板覆盖于整个B柱加强板另一侧的凹形开口面上,形成封闭环状结构;A柱上加强板还与B柱加强板焊接固定;本发明提供的方案,使得车辆碰撞传力路径较为顺畅,避免了A柱折弯风险,增强连接,显著提升白车身的扭转刚度,消除异响风险,同步提升汽车的安全品质和感官品质。
