AI Technical Summary
Technical Problem
The hinge configuration of the wireless earphone charging case takes up space, restricts component expansion, and affects the aesthetics.
Method used
A flexible sheet is used to connect the flip cover to the box body. The flexible sheet is concealed inside, achieving a continuous seam and a clean appearance between the flip cover and the box body. Different tensile moduli of the flexible core layer and flexible surface layer are used to improve stability and strength.
Benefits of technology
Optimize visual aesthetics, reduce space occupation, and increase the possibility of expanding other components or battery capacity.

Abstract
This invention provides a box structure, including a box body, a hinged lid, and a flexible plate. The hinged lid is connected to the box body via the flexible plate. A portion of the flexible plate forms a first section fixed to the interior of the hinged lid, and another portion forms a second section fixed to the interior of the box body. The flexible plate includes a flexible core layer, a first flexible surface layer, and a second flexible surface layer. The tensile modulus of the flexible core layer is greater than the tensile modulus of the first and second flexible surface layers, and the flexible core layer is sandwiched between the first and second flexible surface layers.
