The invention relates to a novel middle channel reinforcing plate assembly which comprises a middle channel front reinforcing plate, a middle channel reinforcing plate and a middle channel middle reinforcing beam, the middle channel front reinforcing plate is upwards folded and inclined relative to the middle channel reinforcing plate, and the middle channel middle reinforcing beam is downwards folded and inclined relative to the middle channel reinforcing plate. A middle channel front reinforcing plate and a first welding square nut are subjected to projection welding to form a first assembly, the middle channel reinforcing plate, a second welding square nut and a first end face projection welding bolt are subjected to projection welding to form a second assembly, the rear end of the first assembly and the front end of the second assembly are connected through welding spots to form an assembly, and a middle channel middle reinforcing beam, a second end face projection welding bolt, a third welding square nut and a bearing face projection welding bolt are welded to form a third assembly. The connecting face of the rear end of the middle channel reinforcing plate and the connecting face of the front end of the middle channel middle reinforcing beam are connected into a whole through spot welding. According to the invention, the utilization of the space in the vehicle is optimized, the comfort of passengers in the back row is greatly improved. Meanwhile, the technical problem that the aluminum floor panel cannot be directly connected with the thermally-formed middle channel is solved.

    本发明涉及一种新型中通道加强板总成,包括中通道前加强板、中通道加强板和中通道中部加强梁,中通道前加强板相对中通道加强板向上翻折呈倾斜状,中通道中部加强梁相对中通道加强板向下翻折呈倾斜状,中通道前加强板与焊接方螺母一凸焊成组件一,中通道加强板、焊接方螺母二、端面凸焊螺栓一凸焊成组件二,组件一后端与组件二前端通过焊点连接成总成,中通道中部加强梁与端面凸焊螺栓二、焊接方螺母三、承面凸焊螺栓焊接成组件三,中通道加强板后端的连接面与中通道中部加强梁前端的连接面通过点焊连接为一体;本发明优化了车内空间利用,大大提高后排乘员的舒适性,同时解决了铝的地板面板无法直接和热成型的中通道连接的技术问题。
