AI Technical Summary

Technical Problem

Existing vibration dampers have a narrow range of vibration suppression frequencies, making them unsuitable for power battery systems in engineering machinery that experience large vibrations and a wide frequency range. Furthermore, existing variable stiffness vibration dampers are expensive.

Method used

Design a shock absorber device, including a sleeve, a rubber shock absorber body and a gasket. The end face of the gasket is provided with an annular concave surface. When the bolt head and nut are tightened, the compression area of ​​the rubber shock absorber body changes with the amplitude. Through the cooperation between the annular concave surface and the rubber shock absorber body, broadband vibration suppression performance is achieved.

Benefits of technology

It achieves wider bandwidth vibration suppression performance, has a simple and compact structure, low cost, and is suitable for power battery systems in engineering machinery.

Abstract

This utility model discloses a shock absorber device, a shock-absorbing structure, and engineering machinery, including a sleeve and bolts. The sleeve extends vertically along its axial direction. A coaxially arranged rubber shock absorber is fitted onto the outer wall of the sleeve. The outer wall of the rubber shock absorber has a coaxially arranged annular groove. Gaskets are respectively provided at the upper and lower ends of the sleeve. A bolt mounting hole is provided in the middle of each gasket. The rubber shock absorber is located between the gaskets at the upper and lower ends. The end face of each gasket facing the rubber shock absorber has a coaxially arranged annular concave surface. The bolt includes a threaded rod and a bolt head. The bolt head is located at the bottom end of the threaded rod, and the top end of the threaded rod is threadedly connected to a nut. The middle part of the threaded rod passes through the interior of the sleeve and the bolt mounting holes of the two gaskets. This utility model improves the structure of the gaskets, allowing the compression area of ​​the shock absorber to change with its amplitude, thus achieving greater broadband vibration damping performance.
