The invention relates to a connecting structure for a front cross beam and a side wall of an extruded aluminum top cover, and relates to the technical field of automobile design and manufacturing. According to the connecting structure for the front cross beam and the side wall of the extruded aluminum top cover, an upper metal plate connector plate and a lower metal plate connector plate are arranged on the two sides of the front cross beam of the extruded aluminum top cover correspondingly, and the upper metal plate connector plate and the lower metal plate connector plate are connected with the front cross beam of the extruded aluminum top cover through hot melting self-tapping screws correspondingly; the side wall outer plate assembly comprises an upper extending end and a lower extending end, and a pre-lap-joint buckle is arranged at the lower extending end and is in pre-lap joint with the lower metal plate connector plate. The lower extending end is welded to the lower metal plate connector plate, and the upper extending end is welded to the end of the upper metal plate connector plate and the end of the lower metal plate connector plate. The connecting structure is subpackaged into the extruded aluminum top cover front cross beam assembly through the hot melting self-tapping screws in advance, so that spot welding connection of a final assembly line can be realized, the cost can be reduced, and the final assembly efficiency can be improved.

    本发明涉及一种挤压铝顶盖前横梁与侧围的连接结构,涉及汽车设计与制造的技术领域。本发明的挤压铝顶盖前横梁与侧围的连接结构,所述挤压铝顶盖前横梁的两侧分别设置有上钣金接头板和下钣金接头板,上钣金接头板和下钣金接头板与分别与挤压铝顶盖前横梁通过热熔自攻螺钉连接;侧围外板总成包括上伸出端和下伸出端,下伸出端上设置有预搭卡扣,所述预搭卡扣与下钣金接头板预搭接;下伸出端与下钣金接头板焊接,上伸出端分别与上钣金接头板和下钣金接头板的端部焊接。本发明的连接结构预先通过热熔自攻螺钉分装成挤压铝顶盖前横梁总成,从而可以实现总装线的点焊连接,可以降低成本,提高总装效率。
