Abstract (en)
[origin: EP4062792A1] Provided is a trolley case, including an upper shell and a lower shell hinged to the upper shell, an inner side of the upper shell and an inner side of the lower shell being each provided with a reinforcing strip, the reinforcing strip being disposed at an inner periphery near an opening of each of the upper shell and the lower shell, and when the upper shell and the lower shell are closed together, the reinforcing strips disposed on the inner side of the upper shell and the inner side of the lower shell forming a support area to prevent the upper shell and the lower shell from deforming and to jointly support a case body. A clearance space exists between the reinforcing strip and the inner periphery of the upper shell or the inner periphery of the lower shell, the reinforcing strip includes strip sheets and connecting blocks, each connecting block connecting two adjacent strip sheets, and the strip sheets and the connecting blocks are alternately arranged, where the strip sheet forms a hollow space together with the inner side of the upper shell or the inner side of the lower shell, and a reinforcing block is provided between the strip sheet and the inner periphery of the upper shell or the inner periphery of the lower shell. By providing the hollow space via the strip sheets, the connecting blocks between adjacent strip sheets, and the reinforcing blocks, the reinforcing strip can have an appropriate strength with hollow structures, thus reducing an overall mass of the case body and preventing deformation of the case body.
