Background

Luggage, also called travel suitcase, is one kind of luggage, usually includes a suitcase body, a telescopic draw bar and bottom wheels, and is widely used because of its convenient use. Luggage cases have a long history, and the luggage cases in the hands of people are evolving from wooden cases and large leather cases which are only used for accommodating clothes, to portable suitcases and draw-bar cases with different shapes nowadays. The aluminum alloy luggage case is one of the luggage cases, and is obtained by performing stretch forming on an aluminum plate blank to obtain an aluminum alloy case shell, and then assembling the aluminum alloy case shell and accessories. Because the drawing rate of the aluminum sheet blank has a technological limit, which results in a limited depth of the inner cavity of a single case, the existing aluminum alloy luggage cases all adopt a split structure, as shown in fig. 1, two cases 101, 102 with substantially the same inner cavity depth are fastened together by a fastener 103. When in use, the two cases are buckled after the articles are fully placed in the two separate cases. Compared with the conventional flip-open type luggage case (i.e. the luggage case with the upper cover structure arranged on the case shell with the deeper inner cavity), the two-piece structure luggage case has less accommodated articles under the condition of the same inner cavity volume, and particularly has far lower capacity than the flip-open type luggage case when large articles are placed. The aluminum alloy luggage case is limited by the process, and the tensile rate of the aluminum plate blank cannot be improved, so that the aluminum alloy luggage case cannot be made into a traditional flip structure.
