Latest Patents

Xu’s recent patents address hinge movement and secondary-screen functionality.

- **Motorized hinge drive device, hinge device, and electronic device.** This invention describes a motorized drive system built around two oppositely arranged lead screws and a shared nut. Its components include first and second flip-drive assemblies, each with sliders and rotation arms, along with a spring assembly and motor assembly. The design enables automatic folding and unfolding while supporting stable hovering.

- **Mobile terminal.** This invention describes a mobile terminal with a main screen and a secondary screen mounted on a middle frame. In the folded state, the secondary screen sits behind or beside the main screen. A piezoelectric actuator fixed between the frame and secondary screen converts transverse deformation into longitudinal force, making the screen vibrate and produce sound and tactile feedback. The actuator is also described as improving the device’s structural firmness and supporting waterproof and dustproof performance.
