Luggage has a long history. From wooden boxes and large suitcases that only contain clothes, to portable suitcases and trolley cases of various shapes, the suitcases in people's hands are constantly evolving. Aluminum alloy luggage is a kind of luggage. The aluminum alloy case is obtained by stretching the aluminum sheet blank, and then the aluminum alloy case and accessories are assembled to obtain the aluminum alloy luggage. Since the stretch rate of aluminum sheet blanks has a technological limit, the inner cavity depth of a single box shell is limited. Therefore, the existing aluminum alloy suitcases adopt a split structure, as shown in Figure 1, which generally have the same inner cavity depth. The two box shells 101 and 102 are buckled together and fastened by a lock 103. In use, it is necessary to buckle the two box shells together after filling the items in two separate box shells. Compared with the traditional clamshell-type luggage case (that is, the luggage case with the upper cover structure on the case with a deeper inner cavity), this kind of double-opening structure luggage case has the same inner cavity volume. , But there are fewer items to hold, especially when placing large items, the capacity is far inferior to the clamshell structure.
