The patent application (Publication Number: US20240040725A1) describes a unique hinge design for a mobile terminal with an infolding flexible screen. The hinge comprises a left side structure and a right side structure, each equipped with a mechanism involving a push-pull rod and a fixed base to facilitate sliding of a housing connector. Additionally, a rotation member and movable guide rail are included to enable synchronous rotation and sliding about the same axis. A rotation support plate is strategically positioned to support the flexible screen when unfolded and prevent bulging when folded. The hinge also features a synchronous reverse rotation connecting structure to ensure synchronized and reverse rotation of the left and right side structures.

Furthermore, the hinge design includes an operation feedback mechanism and is specifically tailored for a mobile terminal with an infolding flexible screen. The inner side of the rotation support plate is rotatably connected to the fixed base, while the housing connector is rotatably connected to the push-pull rod. The movable guide rail is fixed with the housing connector, and the push-pull rod adopts a circular arc sliding block structure. The hinge's components are arranged strategically below the inner flexible screen in the unfolded state, with the fixed base and synchronous reverse rotation connection structure positioned in the middle housing between the left and right housings. Overall, the innovative hinge design aims to provide stability and functionality to mobile terminals with flexible screens, enhancing user experience and device durability.
