AI Technical Summary

Technical Problem

Existing long-stroke buffer mechanisms in ship bridges suffer from problems such as large space occupation, increased mass, and fixed stiffness, making it difficult to meet the requirements of compact space and variable stiffness buffering.

Method used

The hexagonal truss structure, which employs multi-link connections, includes end three-ring telescopic mechanisms and hexagonal prism three-ring telescopic mechanisms. It utilizes a combination of springs and tension springs to provide a large compression ratio and designable stiffness, and transmits restoring forces through links and joints for buffering.

Benefits of technology

It achieves large-stroke buffering within a compact space, possesses structural stability and designable stiffness, adapts to different buffering needs, and reduces the space and weight occupied by the mechanism.

Abstract

This invention discloses a large compression ratio hexagonal prism elastic telescopic mechanism with a stable structure, comprising two end three-ring telescopic mechanisms and several series-connected hexagonal prism three-ring retraction mechanisms. The two ends of the series-connected hexagonal prism three-ring telescopic mechanisms are connected to the end three-ring telescopic mechanisms. Each end three-ring telescopic mechanism includes a central disc, a type I connecting rod, a wing-shaped joint, a type II connecting rod, a spring, a Y-shaped joint, and a tension spring. The end three-ring telescopic mechanisms are located at both ends of the series-connected hexagonal prism three-ring telescopic mechanisms, while the hexagonal prism telescopic mechanisms are located in the middle section. The number of end three-ring retraction mechanisms can be configured according to requirements. The end three-ring retraction mechanisms share the spring, Y-shaped joint, and tension spring with the hexagonal prism three-ring telescopic mechanisms. This invention features a simple structure, a large expansion ratio, structural stability, and freely designable telescopic stiffness. It can be applied to various fields with compact installation spaces and requirements for large stroke and variable stiffness buffering.
