The invention relates to the technical field of automobiles, and discloses an automobile body side impact reinforcing structure which comprises a B column, a doorsill beam, a seat cross beam and a seat mounting bracket which are connected in sequence, the B column comprises a B column outer plate and a B column inner plate connected with the B column outer plate. The doorsill doorsill inner plate connected with the threshold outer plate. The lower end part of the B column outer plate is connected with the doorsill outer plate; the lower end part of the B column inner plate is positioned between the doorsill outer plate and the doorsill inner plate and is arranged in the doorsill cavity; the seat mounting bracket is positioned on the seat cross beam and is connected with the doorsill inner plate; a first crumple energy absorption piece and a second crumple energy absorption piece are arranged in the doorsill cavity, the first crumple energy absorption piece is arranged between the lower end of the B column inner plate and the doorsill outer plate, and the second crumple energy absorption piece is arranged between the lower end of the B column inner plate and the doorsill inner plate. By means of the structure, large local impact energy can be unloaded and transmitted under the side impact working condition, then deformation of the doorsill and the B column is improved, and the safety of passengers during side impact is more fully protected.
本发明涉及汽车技术领域,公开了一种车身侧碰加强结构,其包括依次连接的B柱、门槛梁、座椅横梁和座椅安装支架;B柱包括B柱外板和与B柱外板连接的B柱内板,门槛梁包括门槛外板和与门槛外板连接的门槛内板;B柱外板的下端部与门槛外板连接,B柱内板的下端部位于门槛外板与门槛内板之间并置于门槛腔体内;座椅安装支架位于座椅横梁上并与门槛内板连接;门槛腔体内设有第一溃缩吸能件和第二溃缩吸能件,第一溃缩吸能件设于B柱内板的下端部与门槛外板之间,第二溃缩吸能件设于B柱内板的下端部与门槛内板之间。上述结构能够卸载及传递侧碰工况时较大的局部撞击能量,进而改善门槛及B柱的变形,更充分的保护侧碰时乘员的安全性。
