The invention belongs to the technical field of automobile body structural part design and new material application, and particularly relates to a rear wheel cover and rear longitudinal beam integrated magnesium alloy die-casting structure. The rear wheel cover and rear longitudinal beam integrated magnesium alloy die-casting structure is of an integral die-casting structure integrally integratedby a rear shock absorber seat, a wheel cover front inner plate, a wheel cover rear inner plate, a rear wheel cover front connecting piece, a rear wheel cover sealing plate, a rear longitudinal beam front connecting piece, a rear longitudinal beam rear connecting piece and a rear longitudinal beam outer plate; and the die-casting structure is made of a magnesium alloy material. A plurality of partsof the whole rear wheel cover and the longitudinal beam are integrated into one part structure, the connecting mode is simple, the number of the parts is small, the size precision is high, repeated manual debugging is reduced, and the internal reinforcing characteristic design is adopted, so that excessive connection is avoided, and the whole structural strength is relatively high; and the density of the adopted magnesium alloy is smaller than that of steel aluminum, the weight of the structure is reduced, die-casting forming is facilitated, and the light weight effect is achieved.
本发明属于汽车车身结构件设计及新材料应用技术领域,尤其是一种后轮罩及后纵梁一体化镁合金压铸结构,包括由后减震器座、轮罩前内板、轮罩后内板、后轮罩前连接件、后轮罩封板、后纵梁前连接件、后纵梁后连接件、后纵梁外板一体化集成的整体压铸结构;所述压铸结构采用采用镁合金材料。本发明将整个后轮罩及纵梁多个零件集成为一个零件结构,连接方式简单、零件个数少、尺寸精度高、减少了人工多次反复调试,且内部有加强特征设计无过多连接,整个结构强度较高;且采用镁合金密度较钢铝都小,有利于减轻结构的重量,有利于压铸成型,达到轻量化效果。
