Switchable hinge closure delay structure

Abstract

A retractable hinge retraction and switching delay structure includes: a hinge assembly having a base and at least one switching linkage group, the switching linkage group being pivotally mounted on the side of the base; the switching linkage group having a guided connection component, a guiding linkage, an assembly, and a switching component, the switching component having a guiding part, an unlocking part at one end of the guiding part near the guiding linkage, a guiding surface between the guiding part and the unlocking part, and an elastically guided component at one end of the guided connection component away from the base; when the hinge assembly switches from an extended position to a first retracted position, the guided component is locked by the guiding part, so that the guiding linkage, the switching component, and the assembly can remain fixed in an unswitched state, and when the hinge assembly is in the first retracted position, the guided component can move to the unlocking part to release the locking, so that the guiding linkage, the switching component, and the assembly can be further switched to a second retracted position.

Claims
