The invention relates to the field of automobile internal support and exterior trimming part connection, in particular to an automobile internal support and exterior trimming part connection structure which comprises a front protective skin, and a left side plastic support, a right side plastic support and a middle plastic support arranged between the left side plastic support and the right side plastic support are welded and fixed to the inner side of the front protective skin. The left plastic support, the right plastic support and the middle plastic support are each provided with a plurality of welding parts used for being connected with the front protective skin, the welding parts make contact with the front protective skin, the left plastic support, the right plastic support and the middle plastic support are each provided with a buckle, and at least two welding parts are arranged on the periphery of each buckle. According to the connecting structure for the internal support and the exterior trimming part of the automobile, the welding support is designed into a split type support from an existing integral type support, injection molding deformation of parts is reduced, and the puncture welding firmness between the support and the front protective skin is effectively guaranteed; in order to reduce deformation, the plastic welding bracket is divided into three brackets from one bracket, and the three brackets share one set of mold, so that the appearance size of the mold is reduced, and the cost of the mold can also be reduced.

    本发明涉及汽车内部支架与外饰件连接领域,尤其涉及一种汽车内部支架与外饰件的连接结构,包括前保表皮,所述前保表皮的内侧焊接固定有左侧塑料支架、右侧塑料支架和设置在左侧塑料支架、右侧塑料支架之间的中间塑料支架,所述左侧塑料支架、右侧塑料支架和左侧塑料支架上均设有若干个用于与前保表皮连接的焊接部,且焊接部与前保表皮接触,所述左侧塑料支架、右侧塑料支架和中间塑料支架上均设有卡扣,且卡扣周围至少设有两个焊接部,该汽车内部支架与外饰件的连接结构,焊接支架由现有的整体式支架设计成分体式支架减少零件注塑变形,有效保证支架与前保表皮之间的穿刺焊接牢固性;塑料焊接支架为减少变形将支架由一个支架拆分为三个支架,三个支架共用一套模具,模具外形尺寸减小,还可降低模具成本。
