[0002] Luggage is a commonly used item for people when traveling. The luggage in the prior art is usually composed of two rectangular boxes with one side open, and the two boxes are rotatably connected through a certain side at the joint, and the other three sides are connected by zippers, so that the two boxes can be closed and opened to store items.
[0003] For example, the authorized announcement number "CN204599650U" is a kind of luggage. By setting a flip cover on the box body, items can be taken from the inside of the box body without completely opening the box body, which expands the application range of the existing luggage and enhances the user experience. However, all existing luggage needs to contain various clothes, luggage or other supplies inside the box. The overall luggage is mainly made of cloth or plastic. However, such materials and hollow structures result in insufficient load-bearing capacity of the luggage. When the luggage is pulled out during travel, it needs to be stacked and placed with other boxes or luggage frequently. In this way, the luggage is easily squeezed and deformed or dented. At the same time, some passengers like to sit and lean on the luggage when there is no seat, which is also easy to damage the luggage. Therefore, the load-bearing capacity of the existing luggage is relatively weak during use. Content of the Utility Model
