The invention belongs to the technical field of automobiles, and provides a B stand column area steel-aluminum alloy structure and an automobile, the B stand column area steel-aluminum alloy structure comprises a B stand column assembly and an extruded aluminum doorsill boundary beam, the B stand column assembly comprises a B stand column outer plate, a B stand column upper inner plate and a B stand column lower inner plate, and the B stand column upper inner plate and the B stand column lower inner plate are fixed to the B stand column outer plate; the lower end of the B stand column outer plate and the lower end of the B stand column lower inner plate are both fixed to the extruded aluminum doorsill edge beam, the B stand column assembly further comprises a lower inner plate reinforcing piece, the lower inner plate reinforcing piece is arranged between the B stand column outer plate and the B stand column lower inner plate, and the upper portion of the lower inner plate reinforcing piece is fixed to the B stand column lower inner plate. And the lower part of the lower inner plate reinforcing piece is fixed on the extruded aluminum doorsill edge beam. The connecting strength of the lower area of the B stand column assembly can be improved, and the risk that the connecting portion of the B stand column assembly and the extruded aluminum doorsill edge beam is broken or disengaged when a vehicle collides is reduced.
本发明属于汽车技术领域,提供一种B立柱区域钢铝合金结构及汽车,B立柱区域钢铝合金结构包括B立柱总成和挤压铝门槛边梁,B立柱总成包括B立柱外板、B立柱上内板和B立柱下内板,B立柱上内板和B立柱下内板固定在B立柱外板上,B立柱外板的下端和B立柱下内板的下端均固定在挤压铝门槛边梁上,B立柱总成还包括下内板加强件,下内板加强件设置在B立柱外板和B立柱下内板之间,且下内板加强件的上部固定在B立柱下内板上,下内板加强件的下部固定在挤压铝门槛边梁上。本发明能够提升B立柱总成下部区域的连接强度,降低车辆发生碰撞时B立柱总成与挤压铝门槛边梁的连接部位发生断裂或者脱落的风险。
