The invention discloses a connecting structure of a vehicle body B-pillar and a lower vehicle body doorsill beam. The structure comprises a B-pillar outer plate, a B-pillar reinforcing plate, a B-pillar inner sealing plate and a doorsill beam, and is characterized in that a lower connecting plate is positioned below a main plate body; a bent extending plate is arranged on the lower side of the connecting plate; the B-pillar reinforcing plate is fixed on the inner side of the B-pillar outer plate; the B-pillar inner sealing plate comprises an upper sealing plate and a lower sealing plate whichare connected up and down; the upper sealing plate is arranged at the upper part of the inner side of the B-pillar reinforcing plate; the lower sealing plate is arranged on the lower part of the innerside of the B-pillar reinforcing plate, the edges of plate bodies of the upper sealing plate and the lower sealing plate are fixedly connected with the edges of the B-pillar outer plate and the B-pillar reinforcing plate, the lower connecting plate, the bent extending plate and an outer side face plate of the doorsill beam are fixedly connected, and the lower end of the lower sealing plate is fixedly connected with a top face plate of the doorsill beam. The connecting structure of the vehicle body B-pillar and the lower vehicle body doorsill beam has very high bending resistance and torsion resistance, and the side collision performance is improved. Meanwhile, light weight is achieved through the material selection mode, the cost is not increased, and the practicability is high.

    本发明公开了一种车身B柱与下车体门槛梁的连接结构,包括B柱外板、B柱加强板、B柱内封板以及门槛梁,下连接板位于主板体下侧,在连接板的下侧设有一折弯延伸板,所述B柱加强板固定于B柱外板内侧,所述B柱内封板包括上下连接的上封板以及下封板,上封板置于B柱加强板的内侧上部,下封板置于B柱加强板的内侧下部,上封板与下封板的板体边缘与B柱外板、B柱加强板的边缘之间连接固定,下连接板、折弯延伸板与门槛梁的外侧面板之间连接固定,所述下封板的下端与门槛梁的顶部面板连接固定。所述车身B柱与下车体门槛梁的连接结构,具有很高的抗弯抗扭能力,提高了侧碰性能,同时选材方式也实现了轻量化,不增加成本,实用性高。
