Description

Rotary data storage device shockproof support mechanism

technical field

Background technique

Present computer platforms, such as network servers, desktop computers, and notebook computers, mostly use hard disk devices as large-capacity and permanent data storage devices. In the application of network server, SATA (Serial ATA, where ATA=Advanced Technology Attachment) hard disk device is a widely used data storage device.

In order to meet the minimization requirement of being thin, light and small, the size of the SATA hard disk device used in the network server has reached 2.5 inches at present. However, since the weight of the 2.5-inch hard disk device is relatively reduced, its anti-vibration function is also relatively reduced. The data storage disks in the current hard disk device are all disk-shaped, and when actually performing data reading and writing operations, they rotate around a rotating shaft, thereby allowing the read-write head to perform data reading and writing operations.

However, due to the small weight of the 2.5-inch hard disk device, the torque generated by the rotational motion of the disc-shaped hard disk and the torque caused by external (such as fan) vibration to the disk shaft are very easy to cause the hard disk device to generate a large amount of time. Due to the vibration, the read-write head cannot move to the position accurately and quickly due to the vibration, which affects its read-write action, so that the data access performance of the hard disk device is adversely affected and reduced. In addition, if the hard disk device vibrates too much during actual operation, it will generate a lot of noise and easily make the user feel irritated.

Another object of the present invention is to provide a vibration-proof support mechanism for a rotating data storage device, which can make the hard disk device generate less vibration noise during actual operation.

In a broad sense, the anti-vibration support mechanism for a rotary data storage device of the present invention is designed to be used to install a rotary storage device, such as a hard disk device or an optical disk device, to provide a support for the rotary data storage device. The anti-shock function ensures the data access performance of the rotary data storage device.

Detailed ways

In the following, the embodiments of the anti-vibration support mechanism of the rotary data storage device of the present invention are disclosed in detail in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, the anti-vibration bracket mechanism of the rotary data storage device of the present invention is designed to be applied to the installation of a rotary storage device 10, such as a hard disk device or an optical disc device, and the rotary The conventional data storage device 10 has a data storage chip 20 (such as a magnetic disk or an optical disc), which can rotate around a rotating shaft 21 to perform data reading and writing operations on the data storage chip 20 .

Assume below that the rotary storage device 10 is a hard disk device, then in actual operation, the anti-vibration support mechanism of the rotary data storage device of the present invention can provide a shockproof function to the hard disk device 10, so as to ensure that the hard disk The data access performance of the device 10.

In terms of physical structure, the anti-vibration support mechanism of the rotary data storage device of the present invention at least includes: a frame 110 and a set of heavy objects 120 . The individual properties and functions of these components 110, 120 will be firstly described below.

The frame 110 is used to hold the hard disk device 10, thereby stably supporting the rotational movement of the data storage piece 20 during actual operation. In practice, the frame 110 can be directly the casing of the hard disk device 10 .

The heavy objects 120 are fixed to the above-mentioned frame 110 , and the arrangement of these heavy objects 120 is to surround the rotating shaft 21 of the data storage chip 20 in a symmetrical manner. In practical implementation, these heavy objects 120 can be integrally formed single-piece components, or can be separate multi-piece components. In the embodiment shown in FIG. 1 , the number of heavy objects 120 is four; but in a broad sense, the number is not limited to four, and may be only two, three, five, or more. In addition, in the embodiment shown in FIG. 1 , the shape of the weight object 120 is square; however, in a broad sense, the shape is a random design choice without any special limitation. According to basic kinetic principles:

T(f)=I×α(f)

in

T(f) is the vibration torque generated when the data storage piece 20 rotates plus the torque caused by external (such as fan) vibration, and is a function of the rotation frequency f;

α(f) is the angular acceleration generated by all vibration torques on the data storage sheet 20, and its value will directly affect the data access performance of the hard disk device 10; that is, the larger α(f) is, the smaller the data access performance will be. ;

I is the mass moment of inertia of the weight object 120, and I=k×M×R ² ; where k is a constant, M is the mass of the weight object 120, and R is the distance from each weight object 120 to the rotating shaft 21 (As shown in Figure 1).

It can be seen from the above formula that the best implementation mode of the anti-vibration support mechanism of the rotary data storage device of the present invention is to place these heavy objects 120 at the position with the largest distance from the rotating shaft 21 as possible (that is, the larger the R The better), and increase its mass M to the maximum possible value as much as possible. However, in order to comply with the principle of minimizing the volume, the body of the heavy object 120 is preferably made of a material with high strength and high specific gravity, such as a steel alloy sheet or a copper alloy sheet.

During actual operation, the disk-shaped data storage piece 20 of the hard disk device 10 will rotate around the rotating shaft 21 to perform data reading and writing operations. During this process, the rotational movement of the rotating shaft 21 will generate torque and cause the data storage chip 20 to vibrate. However, the vibration is alleviated by being suppressed by the heavy object 120 , so the vibration phenomenon of the data storage chip 20 can be reduced to ensure the data access performance of the hard disk device 10 . In the same way, external vibrations are also suppressed. In addition, the vibration noise of the hard disk device 10 during actual operation can also be reduced.

In a word, the present invention provides a shock-proof support mechanism for a rotary data storage device, which can be used to install a rotary storage device, such as a hard disk device or an optical disk device, to provide support for the rotary data storage device. An anti-vibration function; and it is characterized in that a group of heavy objects is placed on the frame of the rotating data storage device in a symmetrical manner around the rotating shaft, so as to increase the mass of the hard disk device relative to the rotating shaft of the disk The moment of inertia relatively reduces the angular acceleration of the disc, so that the vibration phenomenon is thus reduced. This feature can make the data access operation of the hard disk device have more stable performance. Therefore, the present invention has better progress and practicability than the background art.
