The invention discloses a connecting structure of a top cover front cross beam and a side wall, and relates to the technical field of automobile design, the connecting structure comprises a top cover front cross beam lower plate, the top cover front cross beam lower plate is connected with a top cover front cross beam connecting plate, the top cover front cross beam lower plate is provided with at least one third cavity, and the third cavity corresponds to a sun shield mounting hole of the top cover front cross beam connecting plate in position. The cavity is reinforced and corresponds to the fastening hole, the large mounting through hole and the plate lap joint transition position, so that the large welding through hole, the large mounting through hole and a collision bending induction area caused by sudden transition of a thick plate and a thin plate of the sun shield are reinforced and greatly reinforced, and the bending resistance and force transmission efficiency of side collision and top pressure are directly improved. The length of the side wall reinforcing plate is shortened, and the cost income brought by increasing the utilization rate of a thermal forming material is obviously improved; the problems that the side wall reinforcing plate is too long and the surface profile tolerance at the section lap joint is difficult to control in the actual production process are directly solved, and the mold debugging difficulty and the part matching rectification period are reduced.

    本发明公开了一种顶盖前横梁与侧围的连接结构,涉及汽车设计技术领域,该装置包括:顶盖前横梁下板,其与顶盖前横梁连接板相连,顶盖前横梁下板设有至少一第三空腔,第三空腔与顶盖前横梁连接板的遮阳板安装孔位置对应。本发明通过加强空腔,并使空腔与紧固孔、大安装过孔以及板料搭接过渡位置对应,以补强大幅加强遮阳板的大焊接过孔、大安装过孔以及厚板与薄板突变过渡导致的碰撞折弯诱导区域,直接提升了侧碰、顶压的抗折弯能力和传力效能。本发明中缩短侧围加强板长度,明显改善热成型材料利用率提升带来的成本收益;直接解决侧围加强板偏长,解决实际生产过程中型面搭接处面轮廓度公差难以控制的问题,减低模具调试难度和零件匹配整改周期。
