PROBLEM TO BE SOLVED: To provide a structure of a case body of a suitcase.SOLUTION: In the main structure of the invented suitcase, a case frame made of aluminum alloy whose width is equal to the depth of a case lid body and a planar plate part made of carbon fibers are combined, a suitcase opening in a curved place of a bottom plate of the case lid body has the same structural strength, the stress is unevenly dispersed after receiving the force and the problem that the suitcase could be damaged is avoided. Furthermore, the combination of the case frame of aluminum alloy and a plate part of carbon fibers makes weight saving of the suitcase and achieves significant decrease in manufacturing difficulty of the carbon fiber case body of the suitcase.SELECTED DRAWING: Figure 2 |
