Disclosed is a lightweight tailgate assembly. According to the present invention, in the lightweight tailgate assembly, a tailgate is applied to a hatchback type vehicle. The lightweight tailgate assembly comprises: an outer panel formed by integral injection molding of a ring-shaped window frame portion, in which a rear window is positioned, and a body portion forming the rear of a vehicle body at a lower end portion thereof; and an inner panel injection molded into a shape corresponding to the outer panel, and coupled to the outer panel while forming a space therebetween by an adhesive applied along a bonding line at a predetermined position. According to the present invention, the tailgate is quickly and accurately assembled by coupling the outer panel and the inner panel, each manufactured in an injection molding manner capable of integrating complex shapes, by using the adhesive applied quantitatively to a correct position along the bonding line at the predetermined position. Therefore, the lightweight tailgate is achieved, fewer parts are required for assembly, and a coupling method is simplified, thereby reducing the assembly process and production costs.

    경량화된 테일게이트 조립체가 개시된다. 본 발명에 따른 경량화된 테일게이트 조립체는, 해치백 타입의 차량에 적용되는 테일게이트로서, 리어윈도우가 위치하는 링형의 창틀부와, 그 하단부에서 차체의 후미를 형성하는 몸체부가 일체로 사출성형되어 이루어진 아우터패널; 및 상기 아우터패널에 대응하는 형상으로 사출성형되어 소정 위치의 접합라인을 따라 도포된 접착제에 의해 상기 아우터패널과 이격공간을 형성하며 결합되는 이너패널을 포함하는 것을 특징으로 한다. 본 발명에 의하면, 복잡한 형상을 일체로 구현할 수 있는 사출성형 방식으로 각각 제조된 아우터패널과 이너패널이 소정 위치의 접합라인을 따라 정확한 위치에 정량으로 도포된 접착제에 의해 결합되는 방식으로 테일게이트에 대한 조립이 신속하고 정확하게 이루어짐에 따라 테일게이트에 대한 경량화는 물론이고, 조립에 필요한 부품수의 최소화와 결합방식의 단순화로 인해 조립공정의 단축과 생산비용의 절감이 도모되는 효과가 있다.
