A universal joint type damper hinge

Abstract

The invention discloses a universal joint type damper hinge. The universal joint type damper hinge comprises a support, a plug, a mounting seat, a positioning plate, a linear damper, a universal joint, a first connecting block and a second connecting rod, wherein the support and the plug are fixed; the other end of the plug is hinged to the mounting seat through a rotating shaft; the positioning plate is arranged on the outer side of a moving end of the linear damper; a positioning groove is formed in the positioning plate; the tail of the linear damper and the mounting seat are fixed; the moving end of the linear damper is clamped in the positioning groove through a pivot; one end of the universal joint is hinged to the plug; the other end of the universal joint is hinged to the first connecting block; one end of the second connecting rod is hinged to the first connecting block; and the other end of the second connecting rod is hinged to the pivot. The universal joint type damper hinge has the advantages that the space utilization ratio is high, parts are arranged reasonably, the structure is compact, the whole universal joint type damper hinge is attractive, the damping effect begins to be achieved when the rotating angle of a cover plate is within 10 degrees, the universal joint type damper hinge runs stably, the effective travel is long, and the cover plate descends stably.

Description

technical field [0001] The invention relates to a damper hinge, in particular to a universal joint type damper hinge. Background technique [0002] All kinds of friction and other obstructions that attenuate free vibration are called damping, and the "special" components placed on the structural system can provide resistance to movement and the device that consumes movement energy is called a damper. A device is a device that provides resistance to movement and consumes movement energy. Dampers are widely used in aerospace, aviation, military, guns, automobiles and other industries. Among them, rotary dampers are more commonly used, but when the rotation angle of the rotary damper is within 10 degrees, the damping effect is not obvious, and the user experience is very poor. Difference. However, the existing hinges for installing dampers generally occupy a large space, have too many and complicated parts, and the idle travel of the hinges is relatively large, which cannot m...

Problems solved by technology

Dampers are widely used in aerospace, aviation, military, guns, automobiles and other industries. Among them, rotary dampers are more commonly used, but when the rotation angle of the rotary damper is within 10 degrees, the damping effect is not obvious, and the user experience is very poor. Difference

However, the existing hinges for installing dampers generally occupy a large space, have too many and complicated parts, and the idle travel of the hinges is relatively large, which cannot meet the current requirements of fast response and small size.
