Example Embodiment

[0027] The present invention will be further described below in conjunction with the drawings.

[0028] Such as Figure 1 to 4 The shown one kind of shock and noise reduction mechanical hard disk assembly includes a hard disk 3, and both sides of the hard disk 3 are provided with noise reduction mechanisms. The noise reduction mechanism includes a splint 1 and a noise reduction plate 2, between the splint 1 and the hard disk 3. There is a pressing structure 6 for pressing the noise reduction plate 2 between the splint 1 and the hard disk 3. The noise reduction plate 2 is clamped between the splint 1 and the hard disk 3. The noise reduction plate 2 is an elastic piece with elasticity. The noise board 2 has a wavy plate structure.

[0029] The noise reduction plate is pressed against the surface of the mechanical hard disk through the splint, the vibration is buffered by the elastic noise reduction plate, and the noise generated in the hard disk is absorbed by the wave-shaped noise ...

Abstract

The invention discloses a shock-absorbing and noise-reducing mechanical hard disk assembly, which includes a hard disk. Noise-reducing mechanisms are provided on both sides of the hard disk. The noise-reducing mechanism includes a splint and a noise-reducing plate. The noise reduction plate is clamped between the splint and the hard disk; the compression structure includes a clamping frame and two fixed plates, and the fixed plates are located at the head and tail of the hard disk; the noise reduction plate is in the shape of a close-packed triangular pyramid in the shape of a wave Structure, the noise reduction plate is provided with a cone groove, the cone groove is in the shape of a triangular pyramid sunken downward; the cone groove is equipped with a noise reduction ball, and the noise reduction ball is filled with a buffer solution for reducing vibration, and the buffer solution is a viscous liquid. The noise reduction plate is pressed against the surface of the mechanical hard disk by the splint, the vibration is buffered by the elastic noise reduction plate and the viscous liquid inside the noise reduction ball, and the noise generated in the hard disk is reduced by the wave-shaped noise reduction The liquid in the plate and the noise reduction ball absorbs the energy and reduces the noise of the hard disk.

Description

technical field [0001] The invention relates to a data storage device, in particular to a shock-absorbing and noise-reducing mechanical hard disk assembly. Background technique [0002] A mechanical hard disk is a traditional ordinary hard disk, which is mainly composed of: disk, magnetic head, disk shaft and control motor, head controller, data converter, interface, cache and other parts. The magnetic head can move along the radial direction of the disk, coupled with the high-speed rotation of the disk at several thousand revolutions per minute, the magnetic head can be positioned on the designated position of the disk for data read and write operations. The information is written to the disk by the electromagnetic current changing the polarity of the magnetic head through the head very close to the magnetic surface, and the information can be read in the opposite way. [0003] Due to the high-speed rotation of the disk, a large vibration will be generated. If the hard dis...
