Abstract
A method for damping the vibration of hard disc for computer is characterized by that a vibration damper is arranged on the joint part between hard disc body and its holder for decomposing the vibration in X and Y directions and a buffer is used between said holder and joint part for damping the vibration in Z direction. Said vibration damper is composed of hard disc body, its holder, screw, rubber ring and spacer.
Description
Technical field
The present invention relates to the fixing method and structure of hard disc of computer and hard disk rack, especially a kind of oscillation damping method of hard disc of computer and device thereof belong to the computer equipment field.
Background technology
At present, our common employed hard disc of computer is by four inch screws hard disk to be fixed on the hard disk rack, hard disk all is directly to be connected with hard disk rack and screw with hard disk and hard disk rack, hard disk just will shake by hard disk rack and screw has directly passed to cabinet, its shortcoming is along with the rotation speed of hard disk constantly speeds, and can produce bigger noise and vibrations when operation, and vibrations can be passed to cabinet, cause the resonance of cabinet, therefore ad hoc meter vibration absorber slows down the vibrations and the noise of hard disk.
Summary of the invention
The object of the present invention is to provide a kind of oscillation damping method and device thereof of hard disc of computer, it can overcome hard disk and rotate noise and the vibrations that computer-chronograph produces.
Another purpose of the present invention is to provide a kind of oscillation damping method and device thereof of hard disc of computer, and it can overcome owing to the noise that produces of vibrations and the resonance of cabinet between hard disk and hard disk rack and the screw.
The objective of the invention is to be achieved through the following technical solutions:
A kind of oscillation damping method of hard disc of computer, which comprises at least: fixedly connected between hard disk main body, hard disk rack is provided with shock attenuation device, shock attenuation device is provided with interference fit in the joint portion of hard disk main body, hard disk rack, makes it to produce the vibrations decomposing force in X, Y direction.Also have, buffering is set between hard disk rack and stationary installation cooperates, the vibration that produces Z-direction slows down.
A kind of hard disc of computer vibration absorber comprises hard disk main body, hard disk rack, screw, cushion rubber and pad, and cushion rubber and pad are set on the screw, and links together with hard disk main body and hard disk rack.
Described screw comprises screw thread, polished rod and nut three parts, and polished rod partly is arranged between screw thread and two parts of nut, and polished rod partly is coarser than threaded portion.
Described cushion rubber is stair-stepping structure, is provided with salient point at the endoporus of cushion rubber and the surface that cooperates with pad, and the length of cushion rubber is longer than the polished rod part of screw.
The mating holes place of described hard disk rack and cushion rubber is designed to turnup structure.
The invention has the beneficial effects as follows:
(1), because being set, a cushion rubber realizes vibration damping between hard disk main body, hard disk rack, screw, and adopt quadruplet screw, cushion rubber, pad and hard disk rack and a hard disk main body to form a hard disk vibration insulating system, and the part of the polished rod by screw with slow down the vibration of hard disk cooperating of cushion rubber circumference along X, Y direction, slow down the vibration of Z-direction by the cushion rubber that is provided with between screw cap and the hard disk rack, overcome hard disk and rotate the noise that computer-chronograph produces and the resonance of vibrations and cabinet.
(2), be designed to turnup structure, increase the contact area of cushion rubber, avoid when making drop test, cushion rubber being caused damage at the mating holes place of hard disk rack and cushion rubber.
(3), through testing authentication, this cover hard disk vibration insulating system effect is fine, complete machine can make noise reduce 1.5dB in idle condition, hard disk can make the complete machine noise reduce about 1.5dB to 5dB in working order.

Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
The oscillation damping method of a kind of hard disc of computer of the present invention, as shown in Figure 6, the transmission coordinate direction of set vibration absorber vibration force.Which comprises at least: fixedly connected between hard disk main body, hard disk rack is provided with shock attenuation device, and shock attenuation device is provided with interference fit in the joint portion of hard disk main body, hard disk rack, makes it to produce the vibrations decomposing force in X, Y direction.Also have, between hard disk rack and stationary installation clearance fit is set, the vibration that produces Z-direction slows down.
By shown in Figure 1: this hard disk unit comprises hard disk main body 1, hard disk rack 2, cushion rubber 3, pad 4, screw 5; Screw 5 is designed to screw special, has one section polished rod part 6 that is coarser than thread end between the threaded portion of screw 5 and nut part, and polished rod part 6 plays three effects:
A, because polished rod part 6 diameters are thicker than threaded portion diameter, so play the fixing spacing effect of screw thread and reach the effect of screw check of allowing.
After b, screw 5 are fixing, by cooperating of polished rod part 6 and cushion rubber 3, the vibrations that slow down hard disk main body 1 by cushion rubber 3 to hard disk rack 2 transmission.
C, the position-limiting action by polished rod part 6 have certain precompressed effect to cushion rubber 3 in the time of can realizing installing, and prevent from again simultaneously cushion rubber 3 damaged by pressure and lose the effect of vibration damping, and cushion rubber 3 is played a protective role.
Hard disk rack 2 is designed to turnup structure 8 with the mating holes place of cushion rubber 3, increases the contact area of cushion rubber 3, avoids when making drop test, and cushion rubber 3 is caused damage.
By said method and device one cushion rubber 3 is set between hard disk main body 1, hard disk rack 2, screw 5 and realizes vibration damping, and adopt quadruplet screw 5, cushion rubber 3, pad 4 and hard disk rack 2 and a hard disk main body 1 to form a hard disk vibration insulating system, polished rod part 6 by screw 5 is slowed down the vibration of hard disk along X, Y direction with the interference fit of cushion rubber 3 circumference, slow down the vibration of Z-direction by the cushion rubber 3 that is provided with between screw cap and the hard disk rack 2, and cushion rubber 3 external diameters before assembling with hard disk main body 1 on hole 9 adopt clearance fit.
