Document Type and Number:
WIPO Patent Application WO/2022/116993
Kind Code:
A1
Abstract:
A trolley case (A), comprising an upper cover (10) and a lower cover (20) which is can open and close with the upper cover (10). Ribs (30) are respectively provided on the inner side of the upper cover (10) and the inner side of the lower cover (20), and the ribs (30) are located at inner side circumferences close to open-close positions of the upper cover (10) and the lower cover (20). When the upper cover (10) and the lower cover (20) are closed, the ribs (30) located on the inner side of the upper cover (10) and the inner side of the lower cover (20) form a support area for preventing the upper cover (10) and the lower cover (20) from deforming, and jointly support a case body. There is a specific gap space (S) between the ribs (30) and the inner side circumference of the upper cover (10) or between the ribs (30) and the inner side circumference of the lower cover (20). The ribs (30) comprise rib plates (301) and connecting blocks (302) connecting two adjacent rib plates (301), and the rib plates (301) and the connecting blocks (302) are alternately arranged. A hollow notch (Q) is formed between the rib plates (301) and the inner side of the upper cover (10) or between the rib plates (301) and the inner side of the lower cover (20), and a first reinforcing rib block (303) is disposed between the rib plates (301) and the inner side circumference of the upper cover (10) or between the rib plates (301) and the inner side circumference of the lower cover (20). By means of providing the hollow notch (Q) in the rib plates (301), disposing the connecting blocks (302) between two adjacent rib plates (301), and disposing the first reinforcing rib block (303), the ribs (30) can have a specific strength while having a hollow structure, so that the overall weight of the case body is reduced and deformation of the case body can be prevented.
