Description

Universal hard disk simulation counterweight jig
Technical Field
The invention relates to a universal type hard disk simulation counterweight jig, in particular to a universal type hard disk simulation counterweight jig for simulating the weight of various hard disks.
Background
In the existing electronic storage technology, the storage device may be generally divided into a Hard Disk Drive (HDD) and a Solid State Disk (SSD), where the HDD is mainly composed of a Disk, a magnetic head, a Disk rotating shaft, a control motor, a magnetic head controller, a data converter, an interface, and a buffer, and the magnetic head can move along the radial direction of the Disk, and the Disk can rotate at a high speed of several thousand rotations per minute, so that the magnetic head can be positioned at a designated position of the Disk to perform data reading and writing operations, and further, by using a magnetic head close to a magnetic surface, data can be written onto the Disk by electromagnetic current in a manner of changing the polarity by electromagnetic current, and the data can also be read by an opposite manner.
On the other hand, since the SSD is a hard disk made of an array of solid-state electronic memory chips, rather than mechanically reading and writing data, the data reading and writing of the SSD is less susceptible to external vibrations. In addition, SSD still has a plurality of characteristics such as read-write speed is fast, antidetonation anti-falling nature is good, the consumption is low, noiseless and light, but the price of SSD is more expensive than HDD, therefore the HDD is more suitable for the storage of a large amount of data, and then extensive use is in the server product, belongs to most basic server storage device.
As mentioned above, the mechanical structure of the HDD has poor shock resistance and crash resistance, so that destructive testing such as vibration and impact can be performed in both the structure and packaging departments, and damage to the HDD or micro deformation of the magnetic head and the magnetic disk is likely to occur during the testing, and the read-write speed can be greatly reduced due to the extremely precise mechanical structure of the HDD.
In order to avoid the influence on the functions of the HDD or the server provided with the HDD, the structural problem often needs to be tested and verified for many times, so that the HDD is often damaged, and even if the HDD is not damaged, the performance of the HDD cannot meet the use requirement, and the HDD is scrapped.
In addition, since most of the server products are large-capacity enterprise-level products, and each HDD is not very expensive, the actual HDD products are used for destructive testing, which is extremely wasteful from the viewpoint of cost.
In order to avoid the waste caused by using actual HDD products to perform testing, the existing method mainly collects some scrapped HDDs to perform most destructive testing, but the method still has certain drawbacks, because the weight of the scrapped HDDs is fixed, and the weight of the HDDs has direct influence on whether structural members such as HDD cage and passis are plastically deformed or destroyed, the scrapped HDDs are used to replace the method for testing the HDDs at present to have certain problems, and therefore, the method used at present needs to be improved.
Disclosure of Invention
In view of the advantages of HDD in the prior art, such as low cost and large storage capacity compared to SSD, HDD is still the preferred choice for server to store data. However, the server is used to store data, so that the need of large-capacity storage is mostly existed, and therefore if the actual hard disk is used for destructive testing, the cost is very high, so that the existing method mainly uses the scrapped HDD for destructive testing, but the scrapped HDD is fixed in weight, so that the case or case of the server with more sensitive weight influence cannot be accurately tested for the destructive testing condition when the case or case bears the hard disk with different weight; therefore, the main objective of the present invention is to provide a universal type hard disk simulation counterweight fixture, which can simulate hard disks with different weights according to the needs of users, so that the casing and the chassis can be subjected to destructive testing with different bearing weights.
To achieve the above and other related objects, a first aspect of the present invention provides a universal hard disk simulation counterweight fixture for selectively simulating one of a plurality of hard disk drives to be tested, for being locked to a server rack to be tested, so as to simulate the server rack to be tested to receive a dynamic motion test in a state of locking the hard disk drives to be tested, wherein each of the hard disk drives to be tested has a weight of a hard disk to be tested, the universal hard disk simulation counterweight fixture comprises: a hard disk exterior shell with a containing space; the plurality of balancing weights 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 balancing weight in the accommodating space to the hard disk exterior shell; the total simulated weight of the hard disk exterior shell, the balancing weight and the at least one fixing piece is within a weight tolerance range with the weight of the hard disk to be detected.
In an embodiment of the first aspect, the hard disk exterior shell includes: a bottom for fixedly connecting with the at least one fixing piece; and a frame part integrally formed protruding from the bottom and enclosing the accommodating space with the bottom.
In an embodiment of the first aspect, the frame portion further includes: the two first side edges are respectively connected with the bottom in an integrated manner and are respectively provided with at least one side edge fixing hole; and two second sides which are respectively connected with the two ends of the bottom and the two first sides in an integrated mode.
In an embodiment of the first aspect, the bottom portion further includes at least one weight locking hole for locking the at least one fixing member.
In an embodiment of the first aspect, the frame portion further includes at least one frame locking hole for locking to a frame.
As described above, the universal hard disk simulation counterweight jig provides the hard disk exterior shell for a user to selectively install the counterweight, so that the total simulation weight of the whole universal hard disk simulation counterweight jig is very close to the weight of a hard disk to be simulated, thereby effectively completing the destructive test of the server rack to be simulated with extremely low cost without damaging the actual hard disk due to the destructive test.
