Suspended type shockproof system

Abstract

The invention relates to an anti-vibration system, in particular to a suspended type anti-vibration system used in electronic products such as a CD-ROM drive, a hard disk, an electronic circuit board, etc. The anti-vibration system comprises at least three buffer cells and a plurality of limit parts; the buffer cell comprises a hollow elastic part, a connecting part which is fixedly connected to the upper end face of the elastic part; when in use, the buffer cells are arranged to be a polygon, the connecting part in each buffer cell is fixedly connected with the lower end face of a part needing vibration damping, and all the limit parts are connected to the top face or side of the part needing vibration damping. The suspended type anti-vibration system can isolate the part needing vibration damping from a vibration source, thus preventing the part needing vibration damping from being affected by vibration directly; furthermore, the suspended type anti-vibration system has the advantage of withstanding large longitudinal and transverse continuous vibration shock.

Description

Technical field [0001] The various embodiments of the present invention generally relate to an anti-vibration system, and more particularly to a suspension type anti-vibration system used in electronic products such as optical disc drives, hard disks, and electronic circuit boards. Background technique [0002] Common vibrations are divided into two types: vertical and horizontal. High-frequency vibrations have a great impact on the performance and service life of hard disks, optical drives, etc. in electronic products that are in working condition. For example, in the optical drive, the optical head is fixed on the casing mechanism, and the optical disc is fixed on the rotating spindle. Since the spindle and the optical head are completely separated, when the optical drive is working, this structure cannot withstand any vibration at all. Because once the vibration occurs, the vibration of the optical disc is not synchronized with the case, causing the optical head to deviate fro...

AI Technical Summary

Problems solved by technology

When the vibration is too large, since the disc and the spindle are not rigidly fixed, the vibration of the disc will still be out of sync with the optical head

Therefore, this design still cannot meet some special applications with strong vibration. For example, when the speaker is working, it produces strong, continuous, and irregular vibration. Especially in the subwoofer, the vibration amplitude and acceleration are very large. The existing shockproof optical drive can't handle the demands of this job
