Technical Field

Background

Hinges are mechanical devices used to connect two solid bodies and allow relative rotation between them. The hinge is a constraint formed by connecting two objects through a pin, drilling holes in the two objects, and inserting the pin into the holes after centering. By means of the hinge constraint, if one of the objects is fixed, the other object can only rotate around the axis of the pin and slightly move along the axis of the pin, but cannot move perpendicular to the axis of the pin. Common hinges include a normal hinge and a damped hinge. The common hinge has no buffer effect, and the switch completely depends on the elasticity of the spring, so the noise is larger. The damping hinge is also called a hydraulic hinge, and adapts to the speed of the switch by means of buffering force, but when the damping hinge is opened, the damping hinge needs to be forced to be turned up to any angle to stop the damping hinge. Neither the common hinge nor the damping hinge can realize the two functions of automatic bouncing and stopping after rotating to a required angle.
