Abstract
A suitcase structure includes a back case component, a front lid component and a ring-shaped gusset component. The opposite sides of the ring-shaped gusset component are connected with the edge of the back case component and the edge of the front lid component respectively, so as to form an accommodation space used for being closed. The ring-shaped gusset component includes a plurality of sidewall portions and a plurality of flexible structures linking the sidewall portions. The flexible deformation capability of the flexible structures is greater than the flexible deformation capability of the sidewall portions. The flexible structures has an inclination, and two of the sidewall portions adjacent to each other can be bent and therefore be stacked opposite to each other by the flexible structures linking the two of the sidewall portions.
