Double-damping hardware buffering hinge

By installing dual dampers on the outside of both sides of the hinge, the problem of insufficient buffering effect of single-damping buffer hinges on large or heavy door panels is solved, achieving a stronger and more balanced buffering effect, optimizing the structural layout, and extending the service life.

AI Technical Summary

Technical Problem

Existing single-damping buffer hinges are insufficient for buffering large or heavy door panels, and the damping force is uneven, resulting in unstable closing. Long-term use may affect the fitting accuracy between the door panel and the cabinet, and the limited space of the damper makes it difficult to improve performance.

Method used

Design a dual-damping hardware buffer hinge. By installing dampers on the outside of both sides of the hinge cup and using the internal drive plate and damping plate to transmit force, dual-side synchronous damping is achieved. The dampers are placed outside the fixed shell to release internal space. A longer stroke and more optimized damper are selected.

Benefits of technology

It provides stronger overall cushioning capacity, ensuring smooth door closing, avoiding uneven force, extending service life, optimizing structural layout, and improving cushioning effect and reliability.

Abstract

A double-damping hardware buffering hinge comprises a hinge cup and a hinge arm, the hinge cup and the hinge arm are hinged through an upper rocker arm and a lower rocker arm, and the upper rocker arm and the lower rocker arm swing relative to the hinge cup and the hinge arm to achieve opening and closing of the hinge. The driving plate is connected with a driving arm at the top end of the upper rocker arm; when the hinge is closed, the driving arm pushes the driving plate to slide; a fixing shell is installed outside the receding groove, a damper is arranged in the fixing shell, the two sides of the driving plate extend into the receding groove to be provided with damping plates, the damping plates are connected with the damper, when the hinge is closed, the damping plates push the damper to be compressed, and the damping effect is generated when the hinge is closed. The double-side synchronous damping hinge has the advantages that the dampers are arranged outside the two sides of the hinge cup and driven by the damping plates on the two sides of the internal driving plate respectively, and double-side synchronous damping is achieved.
