Damper based on paper-folding rebounding mechanism

Abstract

The invention discloses a damper based on a paper-folding rebounding mechanism. The damper comprises a piston cylinder, a piston rod and paper-folding structures, wherein the piston rod is arranged ona working cylinder; the paper-folding structures are fixedly connected to the two surfaces of a disc of the piston rod; the other end of each paper-folding structure is fixedly connected with the bottom surface of the piston cylinder; the piston cylinder is filled with viscous fluid; the disc of the piston rod is provided with a plurality of damping holes; and when the piston rod is subjected toan external load, the paper-folding structures are compressed or stretched along a movement direction of the piston rod, and the viscous fluid in the cavity of the piston cylinder on the compressed side enters the other side through the damping holes, thereby achieving a damping effect. The damper has the characteristics of novel, small and compact structure, easiness and convenience in manufacturing, and relatively low cost.

Description

technical field [0001] The invention relates to equipment for shock absorption and buffering, in particular to a damper based on an origami rebound mechanism. Background technique [0002] As a device that reduces vibration or consumes energy, dampers are widely used in various fields of life and production, such as anti-seismic building structures, vibration reduction of cable-stayed bridge zippers, automobiles, aerospace, etc. At present, the commonly used damper types are hydraulic damper, spring damper and so on. The hydraulic damper is a vibration control device that responds sensitively to speed, but it cannot effectively control low-amplitude high-frequency or high-amplitude low-frequency vibrations; the spring damper, as a relatively traditional shock absorber, has a simple structure and principle , can meet the application requirements of many occasions, but it is not sensitive to the speed response. [0003] In recent years, origami has appeared in people's sight...
