The invention discloses a connector structure of an automobile doorsill and a column B and an automobile, and relates to the technical field of automobile body structures. The connector structure comprises a doorsill beam main body, a doorsill reinforcing beam and a supporting plate assembly; wherein a cavity is formed in the doorsill beam main body, a B-pillar inner plate is arranged on the doorsill beam main body, and the B-pillar inner plate partially penetrates through the doorsill beam main body and extends into the cavity. And the doorsill reinforcing beam is assembled in the cavity of the doorsill beam main body. The supporting plate assembly is arranged in the doorsill stiffening beam in a penetrating mode, one end of the supporting plate assembly is connected with the B column inner plate, and the other end of the supporting plate assembly is connected with the doorsill beam body. The doorsill supporting plate is arranged in the doorsill, penetrates through the doorsill for reinforcement and is connected with the inner doorsill, the outer doorsill and the B column inner plate, so that the B column inner plate is directly inserted into the bottom of the doorsill, the joint performance is improved, the bending resistance of a B column can be improved during side collision, deformation of the lower portion of the B column is reduced, and meanwhile the bending resistance of the doorsill and the rigidity of a body in white are improved.

    本发明公开了一种汽车门槛与B柱的接头结构及汽车,涉及车身结构技术领域,该接头结构包括门槛梁主体内、槛加强梁和支撑板总成;其中,门槛梁主体内设有空腔,所述门槛梁主体上设有B柱内板,且所述B柱内板部分穿过所述门槛梁主体延伸到所述空腔内。门槛加强梁,其组设于所述门槛梁主体的空腔中。支撑板总成,其穿设于所述门槛加强梁中,所述支撑板总成一端与所述B柱内板相连,另一端与所述门槛梁主体相连。本申请在门槛内设置门槛支撑板,门槛支撑板穿过门槛加强,并与内外门槛和B柱内板连接,使B柱内板直接插入门槛底部,提升接头性能,在侧碰时能够提升B柱的抗弯性能,减小B柱下部的变形,同时提升门槛的抗弯性能,提升白车身刚度。
