Hinge assembly for folding screen

The invention relates to a hinge assembly for a folding screen. The hinge assembly comprises a mounting base for fixed mounting, and a left overturning assembly and a right overturning assembly which are rotationally arranged on the mounting base and form synchronous overturning through an even number of gear sets; and the left overturning assembly and the right overturning assembly are each provided with a sliding structure in an integrated mode, and damping pieces rotating along with the sliding structures to achieve the damping hand feeling are arranged on the sliding structures. The assembly is simple in structure and high in function integration, and the installation space can be effectively saved. 本发明涉及一种用于折叠屏的铰链组件，包括用于固定安装的安装基座，以及转动设置在安装基座上并通过偶数齿轮组形成同步翻转的左侧翻转组件和右侧翻转组件；左侧翻转组件和右侧翻转组件均集成设计了滑动结构，并且在滑动结构上设置了随滑动结构转动实现阻尼手感的阻尼件。本发明结构简单，功能集成性高，能够有效节省安装空间。
