차량도어조립체는 앞 및 뒤 수직빔들에 의해 상호연결된 상부 및 하부 수평빔들에 의해 필수적으로 형성된 내부패널과, 내부패널에 부착된 외부패널을 포함한다. 프레임부는 연속하는 외주를 형성하도록 상부 및 하부 중간 프레임부재들에 의해 서로 분리-불가능하게 부착된 대향하는 앞 및 뒤 U-형상 측면 프레임부재들을 포함한다. 측면 프레임부재들은 제1 강철재료로 만들어지고, 중간 프레임부재들은 제1 강철재료와는 다른 제2 강철재료로 만들어진다. 내부패널의 제조방법은 제1 강철재료의 U-형상 시트들을 제공하는 단계, 제2 강철재료의 위 및 아래 시트들을 제공하는 단계, 블랭크를 형성하도록 위 및 아래 시트들에 U-형상 시트들을 분리-불가능하게 연결하는 단계, 및 블랭크를 프레임부속으로 스탬핑하는 단계를 포함한다.
A vehicle door assembly comprises an inner panel integrally formed by upper and lower horizontal beams interconnected by front and rear upright beams, and an outer panel bonded to the inner panel. The frame portion comprises opposite front and rear U-shaped side frame members non-detachably attached to each other by upper and lower intermediate frame members so as to form a continuous perimeter. The side frame members are made of a first steel material and the intermediate frame members made of a second steel material, which is different from the first steel material. A method for manufacturing the inner panel comprises the steps: providing U-shaped sheets of the first steel material, providing top and bottom sheets of the second steel material, non-detachably connecting the U-shaped sheets to the top and bottom sheets so as to form a blank, and stamping the blank into the frame portion.
