Description

Universal hard disk simulation counterweight fixture

The invention relates to a universal hard disk simulation counterweight fixture, in particular to a universal hard disk simulation counterweight fixture for simulating the weights of various hard disks.

In the existing electronic storage technology, storage devices can be roughly divided into hard disk drives (Hard Disk Drive, HDD) and solid state hard disk (Solid State Disk, SSD). , control motor, head controller, data converter, interface and cache, etc. The head can move along the radius of the disc, and the disc can rotate at a high speed of several thousand revolutions per minute. It can be positioned on the specified position of the disc to perform data read and write operations, and then use the magnetic head close to the magnetic surface to change the polarity of the electromagnetic current so that the data can be written to the magnetic disc by the electromagnetic current. Reading can also be done in the opposite way.

On the other hand, since the SSD is a hard disk made of a solid-state electronic storage chip array instead of reading and writing data mechanically, the data reading and writing of the SSD is less affected by external vibrations. In addition, SSD also has many characteristics such as fast read and write speed, good shock and drop resistance, low power consumption, no noise, and light weight, but the price of SSD is more expensive than that of HDD, so HDD is more suitable for storage of large amounts of data, and thus widely used. It is used in server products and belongs to the most basic server storage device.

As mentioned above, also because the mechanical structure of HDD has poor shock resistance and anti-drop resistance, destructive tests such as vibration and shock will be carried out in the structure and packaging departments, and the HDD may be damaged during the test process, or There is a slight deformation of the magnetic head and the magnetic plate, and because the HDD is an extremely precise mechanical structure, a slight deformation can lead to a significant decrease in the read and write speed.

In order to avoid affecting the functions of products such as HDDs or servers equipped with HDDs, structural problems often require multiple tests and verifications, which often cause damage to HDDs. Even if HDDs are not damaged, their performance cannot be achieved. usage requirements, which in turn lead to the scrapping of HDDs.

In addition, since most of the server products that are currently used are large-capacity enterprise-level products, the price of each HDD is high. Therefore, using actual HDD products for destructive testing is a cost consideration. Extremely wasteful.

In order to avoid the waste caused by using actual HDD products for testing, the existing method is to collect some scrapped HDDs for most destructive tests, but this approach still has certain drawbacks, because the weight of scrapped HDDs is It is fixed, and the weight of the HDD has a direct impact on whether the structural parts such as the HDD cage and Chassis are plastically deformed or damaged. Therefore, there are certain problems in using scrapped HDDs instead of testing HDDs. Therefore, it is necessary to improve the currently used methods.

In view of the fact that in the prior art, HDD is still the first choice for server to store data due to its advantages of cheapness and large storage capacity compared with SSD. Therefore, if the actual hard disk is used for destructive testing, the cost is very high, so the existing method is mainly to use scrapped HDDs for destructive testing. For a server casing or a chassis, it is impossible to accurately test the destructive test situation when the casing or the chassis carries hard disks of different weights; therefore, the main purpose of the present invention is to provide a universal hard disk simulation counterweight fixture , which can simulate hard disks of different weights according to the needs of users, so that the case and the chassis can be destructively tested with different bearing weights.

Each hard disk drive to be tested has a The weight of the disk includes a hard disk outer shell, a plurality of counterweight blocks and at least one fixing piece.

The outer casing of the hard disk has an accommodating space. The plurality of counterweight blocks are arranged in the accommodating space according to the weight of the hard disk to be tested of the hard disk drive to be tested. The fixing piece is used for fixing the weight block to the outer casing of the hard disk in the accommodating space.

Wherein, the total simulated weight of one of the outer casing of the hard disk, the counterweight and the fixing piece is within a weight tolerance range from the weight of the hard disk to be tested.

In an auxiliary technical means derived from the above-mentioned necessary technical means, the outer casing of the hard disk includes a bottom portion and a frame portion. The bottom is used for fixing at least one fixing piece. The frame part is integrally formed and protrudes from the bottom, and forms an accommodating space with the bottom.

Preferably, the frame portion further includes two first side edges and two second side edges. The two first side edges are integrally connected to the bottom, respectively, and at least one side edge fixing hole is respectively opened.
