The invention relates to a lightweight automobile body B-pillar reinforcing structure, and belongs to the technical field of automobile parts. The structure comprises a B-pillar outer plate, a B-pillar outer reinforcing plate, a B-pillar inner reinforcing plate and a threshold beam, a first bent groove is formed in the side edge of the B-pillar outer plate, a first bent edge of an S-shaped structure is arranged at the bottom of the B-pillar outer plate, a second bent groove is formed in the B-pillar outer reinforcing plate, and a second bent edge is arranged at the bottom of the B-pillar outerreinforcing plate; the B-pillar inner reinforcing plate is installed in the second bending groove, a third bending groove is formed in the B column inner reinforcing plate, and a third bending edge is arranged at the bottom of the B column inner reinforcing plate. The lightweight automobile body B-pillar reinforcing structure has the beneficial effects that the B-pillar outer plate, the B-pillarouter reinforcing plate and the B-pillar inner reinforcing plate are connected together, the threshold beam is fixed to the bottom of the B-pillar outer plate, and therefore the overall strength of the automobile B-pillar is improved, meanwhile, a traditional method of utilizing a large aluminum plate is replaced, and the automobile B-pillar is novel in structure and convenient to operate.
本发明涉及一种轻量化车身B柱加强结构,属于汽车零部件技术领域。包括B柱外板、B柱外加强板、B柱内加强板以及门槛梁,所述B柱外板的侧边设置有第一折弯凹槽,所述B柱外板的底部设置有呈S型结构的第一折弯边,所述B柱外加强板上设置有第二折弯凹槽,所述B柱外加强板的底部设置有第二折弯边,所述B柱内加强板安装于所述第二折弯凹槽里,所述B柱内加强板上设置有第三折弯凹槽,所述B柱内加强板的底部设置有第三折弯边。本发明的有益之处是:将B柱外板和B柱外加强板以及B柱内加强板相互连接到一起,并将门槛梁固定到B柱外板的底部,从而提高了汽车B柱的整体强度,同时也取代了传统的利用大块铝板的做法,本发明结构新颖,操作方便。
