A rubber shock absorber for hard disk vibration reduction

Abstract

The invention discloses a rubber shock absorber used for hard disk shock absorption. The rubber shock absorber for hard disk vibration damping includes: a central connection part for connecting with a hard disk; an outer peripheral connection part for connecting with a mounting bracket, which is arranged on the outer periphery of the central connection part, There is a radial gap between the outer peripheral connecting portion and the central connecting portion; and a connecting arm connecting the central connecting portion and the outer peripheral connecting portion, wherein the central connecting portion and the outer peripheral connecting portion have a thickness direction are staggered from each other, and the central connection part deviates toward the hard disk relative to the outer peripheral connection part. In the rubber shock absorber of the present invention, the connecting arm is used to perform vibration damping between the central connecting portion and the outer peripheral connecting portion, and the central connecting portion and the outer peripheral connecting portion are staggered from each other in the thickness direction (that is, the direction perpendicular to the radial direction) , thus, vibration reduction can be provided in three directions, and the adaptive frequency domain is greatly increased.

Description

technical field [0001] The invention relates to the technical field of hard disk shock absorption, in particular to a rubber shock absorber for hard disk shock absorption. Background technique [0002] Shock absorbers are used in equipment such as servers in mobile or vibrating environments to reduce the damage caused by environmental vibrations on hard drives. [0003] In the prior art, rubber shock absorbers are usually mixed based on rubber elasticity and damping materials, each of which forms a vibration damping effect on its own frequency band. In addition, the existing rubber shock absorbers are usually designed with a solid structure or a flat structure. Solid or flat rubber, when vibrating and impacting, the unidirectional effect is more obvious, and the multi-directional effect is poor, but the vibration in the actual environment is multi-directional; the frequency domain of adaptation is relatively narrow, and the frequency of its vibration reduction effect The p...
