The invention discloses a side wall reinforcing structure and an automobile. The side wall reinforcing structure comprises a side wall and a reinforcing plate, wherein the side wall comprises a coaming structure, the coaming structure comprises a main coaming structure and a connecting coaming structure, the reinforcing plate is arranged on the side wall, the reinforcing plate is integrally arranged, and the connecting coaming structure is connected with the main coaming structure; the reinforcing plate comprises a first reinforcing plate section and a second reinforcing plate section which correspond to the main coaming structure and the connecting coaming structure respectively, the plate thickness of the first reinforcing plate section is larger than that of the second reinforcing platesection, and due to the fact that the thickness of the second reinforcing plate section is smaller than that of the first reinforcing plate section, the weight of the second reinforcing plate sectionis reduced; and meanwhile, the reinforcing plates are integrally arranged, so welding between the reinforcing plates with different thicknesses is avoided, stress concentration at the welding position is eliminated, safety performance of the side wall is guaranteed, and welding cost is prevented from being increased.
本发明公开一种一种侧围加强结构及汽车,其中,侧围加强结构包括侧围和加强板,其中,侧围包括围板结构,围板结构包括主围板结构以及连接围板结构,加强板设于侧围,加强板呈一体设置,加强板包括分别对应主围板结构以及连接围板结构设置的第一加强板段以及第二加强板段,第一加强板段的板厚大于第二加强板段的板厚,由于第二加强板段的厚度小于第一加强版段的厚度,减少了第二加强板段的重量,同时加强板采用一体设置,避免了不同厚度加强板之间的焊接,消除了焊接处的应力集中,既保证了侧围的安全的性能,又避免了增加焊接成本。
