The invention discloses a B-pillar inner plate and a vehicle with the B-pillar inner plate. The B-pillar inner plate comprises a B-pillar inner plate body, a retractor via hole is formed in the B-pillar inner plate body, and the retractor via hole comprises a turnup edge and a non-turnup edge which are cut off through a punching process notch; a reinforcing plate is arranged on the B-pillar inner plate body, and the highest connecting points of the reinforcing plate and the front side and the rear side of the B-pillar inner plate body are located above or obliquely above the stamping process notch. According to the B-pillar assembly, the reinforcing plate is located on the B-pillar inner plate body, the rigidity of the position of the retractor via hole can be remarkably improved, the side impact performance of a whole vehicle can be improved, and the highest connecting point of the reinforcing plate and the B-pillar inner plate body is located above or obliquely above the stamping process notch; and the risk that the B-pillar inner plate body cracks at the notch of the stamping process during side collision is reduced.

    本发明公开了一种B柱内板及具有该B柱内板的车辆。该B柱内板包括:B柱内板本体,B柱内板本体上设有卷收器过孔,卷收器过孔包括通过冲压工艺切口断开的翻边边缘和无翻边边缘;加强板位于B柱内板本体上且加强板与B柱内板本体的前后两侧的最高连接点均位于冲压工艺切口的上方或斜上方。根据本发明的B柱组件,加强板位于B柱内板本体上,可以显著提升卷收器过孔处的刚度,有利于提升整车侧碰性能,且加强板与B柱内板本体的最高连接点位于冲压工艺切口的上方或斜上方,降低了侧面碰撞时B柱内板本体在冲压工艺切口处开裂的风险。
