Hinge with limiting and unlocking functions

The invention relates to a hinge with limiting and unlocking functions. According to the hinge, the hinge limiting function is achieved by a first guiding surface arranged on a first hinge member anda limiting member arranged on a second hinge member, and automatic unlocking of the hinge is achieved through the plan of the distance between a receiving portion of a rotating reset piece and the axis of a hinge shaft and the distance between a limiting section and a disengagement section on the first guiding surface and the axis of the hinge shaft, so that the hinge can realize the functions oflimiting and automatic unlocking, the hinge structure is simple, and implementation is easy. 本发明涉及一种带限位解锁功能的铰链，其通过分别设置在第一铰接件和第二铰接件上的第一导向面以及限位件来实现该铰接的限位功能，而通过旋转复位件上的接纳部以及第一导向面上限位段和脱离段与铰接轴轴心之间距离的规划来实现该铰接的自动解锁，以使该铰接能够实现限位以及自动解锁的功能，且该铰接结构简单，易于实施。
