It should be understood that the specialized circuitry that performs one or more of the various operations disclosed herein may be formed by one or more processors operating in accordance with specialized instructions persistently stored in memory. Such components may be arranged in a variety of ways such as tightly coupled with each other (e.g., where the components electronically communicate over a computer bus), distributed among different locations (e.g., where the components electronically communicate over a computer network), combinations thereof, and so on.
Principles of the present disclosure are now explained with reference to various example embodiments shown in the drawings. It should be appreciated that description of those embodiments is merely to enable those skilled in the art to better understand and further implement the present disclosure and is not intended for limiting the scope disclosed herein in any manner.

Those skilled in the art should understand from the following description that alternative embodiments of the structure and the method described in the text can be adopted without deviating from the principles of the present invention described herein.
As briefly described above, a currently urgent and yet to be solved problem is how the height of the chassis is reasonably utilized to place more storage drive carriers. FIG. 1A schematically illustrates a perspective view of a traditional storage drive carrier 100. To facilitate the following detailed description, the width direction (indicated by D1, also known as “first direction”), the length direction (indicated by D2, also known as “second direction”), and the height direction (indicated by D3, also known as “third direction”) of the storage drive carrier 100 are defined in FIG. 1A. An internal structure of the traditional storage drive carrier 100 will be shown in FIG. 1B.
FIG. 1B schematically illustrates a cross-section view of the traditional storage drive carrier 100 perpendicular to the second direction D2. As shown in FIG. 1B, the storage drive carrier 100 may include a body 110 for receiving a storage drive and a protrusion 120 for receiving a circuit board like PCB. The circuit board is electrically connected with the storage drive for implementing data and power transmission with the storage drive.
FIG. 1C further schematically illustrates a local perspective view of a chassis 10 including the traditional storage drive carrier 100. As shown in FIG. 1C, 8 or any number of storage drive carriers are stored in the chassis 10, and each of storage drive carriers is plugged to a backplate of the chassis 10 in the second direction D2 to implement data and power transmission. Specifically, in FIG. 1B, at the end of the storage drive carrier 100 that enters the sheet, the protrusion 120 is provided with one or more interfaces. The one or more interfaces are laterally provided, some of which are used for transmitting data while the other are used for transferring power to supply power for the circuit board and the storage drive. In other words, the circuit board and the interface for transmitting data and power are disposed on a face of the storage drive carrier 100 perpendicular to the third direction D3.
Remaining space usually exists in the third direction D3 with a height of H1. For example, when the standard height of the chassis 10 is 2U and the storage drive therein is a 3.5″ hard disk, the available height of the chassis 10 is approximately 80 mm, and a sum of height when two layers of 3.5″ hard disks are superimposed is about 64 mm. Therefore, the height H1 of the remaining space is approximately 14 mm. Unfortunately, the height of the 2.5″ hard disk is slightly greater than 14 mm. Considering the actual thickness of the metal shell, the height for receiving the 2.5″ hard disk is around 17 mm. Therefore, the height H1 of the remaining space of the chassis 10 in the third direction D3 cannot be used for inserting other hard disks, which results in wasted space. Similar situations also occur with other sizes of storage drive carriers and chassis. Therefore, the present disclosure is aimed to redesign the structure of the storage drive carrier and the way in which the storage drive carriers are superimposed in the chassis, so as to arrange the storage drive carrier more efficiently and reduce the possibility of space waste.
It should be understood that “storage drive” in the present disclosure can refer to storage apparatuses (e.g., hard disk and the like) implemented in the electronic device, such as 3.5″ hard disk for storing cold data or 2.5″ hard disk for storing hot data etc. It should be appreciated that “storage drive” is not restricted the above listed storage apparatuses and other various types of electronic devices stored in the chassis can be expected.
The redesigned structure of the storage drive carrier and the way in which the storage drive carriers are superimposed in the chassis will be described in details below with reference to the rest drawings.
FIG. 2A schematically illustrates a perspective view of a storage drive carrier 200 in accordance with embodiments of the present disclosure. It can be seen from FIG. 2A that a lower surface of the storage drive carrier 200 is not as flat as the storage drive carrier 100 in FIG. 1A and has a protrusion instead. FIG. 2B schematically illustrates a cross-section view of the storage drive carrier 200 perpendicular to the second direction D2 in accordance with embodiments of the present disclosure. To facilitate the demonstration, the section of FIG. 2B is reversed 180 degrees relative FIG. 2A. As shown in FIG. 2B, the storage drive carrier 200 may include a body 210 and a protrusion 220. As an example, the protrusion 120 is positioned above the body 110. As another example, the protrusion 120 also can be positioned above the body 110.
Similar to FIG. 1B, the body 210 is used for receiving the storage drive while the protrusion 120 is used for receiving the circuit board like PCB. As an example, the storage drive carrier 200 may include the body 210. As shown in FIG. 2A, the body 210 has a first length in the first direction D1, a second length in the second direction D2, and a third length in the third direction D3. For example, the third length may be below the first length, the first length may be further below the second length, and the first direction D1, the second direction D2, and the third direction D3 are perpendicular to one another. Moreover, the storage drive carrier 200 may also include the protrusion 220.
As described above, the circuit board of the traditional storage drive carrier 100 and the interface for transmitting data and power in FIG. 1B are disposed on a face of the storage drive carrier 100 perpendicular to the third direction D3. Different from FIG. 1B, the protrusion 220 of the storage drive carrier 200 including the circuit board in FIG. 2B is disposed at one side of a face of the storage drive carrier 200 perpendicular to the third direction D3, and the length of the protrusion 220 in the first direction D1 is below half of the length of the storage drive carrier 200 in the first direction D1. It should be understood that the specific shape of the storage drive carrier 200 shown in FIGS. 2A and 2B does not constitute the restrictions over the scope of the present disclosure and the storage drive carrier 200 may also be implemented in various suitable forms.
FIG. 3 illustrates, in more details, a perspective view of a storage drive carrier 300 in accordance with embodiments of the present disclosure. As shown in FIG. 3, the storage drive carrier 300 may include a body 310. The body 310 has a first length in the first direction D1, a second length in the second direction D2, and a third length in the third direction D3. As an example, the third length may be below the first length, and the first length may be further below the second length. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to one another. Moreover, the storage drive carrier 300 may further include a protrusion 320.
In some embodiments, the protrusion 320 is arranged together with the body 310 in the third direction D3. As shown in FIG. 3, the protrusion 320 may be positioned within an area delimited by a center line 340 of a face 330 of the body 310 on which the protrusion 320 is provided and sides of the face 330. It should be appreciated that the center line 340 is usually interpreted to bisect the face 330 and to be parallel with the second direction D2. In other words, if the face 330 of the body 310 is divided, along the second direction D2, into two equal parts, the protrusion 320 will be disposed on one of the equal parts according to FIG. 3. A detailed implementation of reducing the length of the protrusion 320 in the first direction D1 will be described in details below.
FIG. 4A schematically illustrates an explosive view of a storage drive carrier 400 in accordance with embodiments of the present disclosure. As shown in FIG. 4A, the storage drive carrier 400 is decomposed, from top to bottom, into a top shell 410, a first circuit board 420 for transmitting data, a storage drive 440, and a bottom shell 460. As described above, the circuit board and the interface for transmitting data and power of the traditional storage drive carrier 100 of FIG. 1B are disposed on a face of the storage drive carrier 100 perpendicular to the third direction D3. Different from FIG. 1B, the first circuit board 420 of the storage drive carrier 400 of FIG. 4A is arranged at one side of a face of the storage drive carrier 400 perpendicular to the third direction D3, and the length of the first circuit board 420 in the first direction D1 is below half of the length of the storage drive carrier 400 in the first direction D1. In other words, the first circuit board 420 is designed to be narrower in the first direction D1 than other directions.
Furthermore, the first circuit board 420 includes a first interface 430 as shown in FIG. 4A. In some embodiments, the first interface 430 may be configured to plug, in the second direction D2, to the backplate of the chassis 10 for receiving the storage drive carrier. As described above, the traditional storage drive carrier 100 includes one or more interfaces laterally arranged on the face 330 and these interfaces are used for data and power transmission to supply power for the circuit board and the storage drive. The difference from the traditional storage drive carrier 100 of FIG. 1B is that, the number of interfaces of the storage drive carrier 400 in FIG. 4A is reduced, in addition to reducing the length of the first circuit board 420 in the first direction D1. As an example, the first interface 430 may be remained only at the end of the first circuit board 420 while the additional interface 450 is arranged at the body below the first interface 430.
FIG. 4B schematically illustrates a local perspective view of an additional interface 450 at the end of the storage drive carrier 400 in FIG. 4A. As shown in FIG. 4B, the additional interface 450 includes a second interface 451 and an intermediate connector 452. The second interface 451 is configured to be plugged, in the second direction D2, to the backplate of the chassis 10 for receiving the storage drive carrier 400 to transfer power. It should be understood that although not shown, the body of the storage drive carrier 400 should also include a second circuit board for supplying power, and the second interface 451 operates on the second circuit board. Alternatively or additionally, the second circuit board for supplying power may also be superimposed with the first circuit board 420 and arranged together in the protrusion. As the second circuit board for supplying power has a relatively simple structure, it is only required to sacrifice the thickness of 2 to 5 layers (e.g., 4 layers) of circuit boards.
In some embodiments, the second interface 451 is configured to connect to the first interface 430 to facilitate supplying power for the first circuit board 420. As an example, the first interface 430 may further be connected, via the intermediate connector 452, to the storage drive 440 to implement functions of data transmission and power supply of the storage drive 440. Preferably, the first interface 430 and the second interface 451 may be combined and jointly plugged to the backplate of the chassis 10.
Accordingly, the protrusion 220 (FIG. 2B) and 320 (FIG. 3) with narrowed width is implemented by transforming a redundant length of the protrusion 120 of the traditional storage drive carrier 100 in the first direction D1 into the slightly increased length in the second direction D2 or in the third direction D3.
FIG. 5 schematically illustrates a cross-section view of two storage drive carriers 300 and 300′ perpendicular to the second direction D2 in accordance with embodiments of the present disclosure. As shown in FIG. 5, the storage drive carrier 300 are superimposed with the additional storage drive carrier 300′ in a centrosymmetric way. Specifically, the protrusion 520 of the storage drive carrier 300 faces other areas 530 of the additional storage drive carrier 300′ except for the area provided with an additional protrusion. Besides, although not demonstrated with reference signs, it should be appreciated that the protrusion of the additional storage drive carrier 300′ also faces other areas of the storage drive carrier 300 except for the area provided with an additional protrusion. Since the protrusion is redesigned to be positioned at one side of the body and the length of the protrusion in the first direction D1 is below half of the length of the body in the first direction D1, the two storage drive carriers 300 and 300′ may be stacked together. In this way, every time two storage drive carriers are superimposed, approximately the thickness of one protrusion in the third direction D3 may be saved. Taking the standard height of the chassis as 2U and the storage drive as a 3.5″ hard disk as an example, the two superimposed storage drive carriers 300 and 300′ may also be stacked with a carrier for receiving a 2.5″ hard disk. Details are explained below with reference to FIG. 6.
FIG. 6 schematically illustrates a cross-section view of three storage drive carriers 300, 300′, and 300″ perpendicular to the second direction D2 in accordance with embodiments of the present disclosure. As shown in FIG. 6, a further storage drive carrier 300″ is superimposed on the two superimposed storage drive carriers 300 and 300′. Similar to FIG. 5, the protrusion 620 of the storage drive carrier 300 in FIG. 6 faces other area 630 of the additional storage drive carrier 300′ except for the area provided with the additional protrusion. Although not demonstrated with reference signs, it should be understood that the protrusion of the additional storage drive carrier 300′ also faces other area of the storage drive carrier 300 except for the area provided with the additional protrusion. In addition, the further storage drive carrier 300′ is configured to receive a further storage drive having a different type than those received in the two storage drive carriers 300 and 300′. As an example, the two storage drive carriers 300 and 300′ are configured to receive the 3.5″ storage drive while the further storage drive carrier 300″ is configured to receive the 2.5″ storage drive.
FIG. 7 schematically illustrates a local perspective view of the chassis 20 in accordance with embodiments of the present disclosure. As shown in FIG. 7, the chassis 20 includes two storage drive carriers 300 and 300′. As the two storage drive carriers 300 and 300′ are stacked in such a manner as to be engaged with each other, the height H2 of the remaining space in the third direction D3 is greater than the height H1 (see FIG. 1C) of the traditionally arranged remaining space. Therefore, the remaining space may further receive the storage drive carrier 300′. As an example, the chassis 20 may have a standard chassis height of 2U and the two storage drive carriers 300 and 300′ are configured to receive the 3.5″ storage drive, while the further storage drive carrier 300″ is configured to receive the 2.5″ storage drive.
Furthermore, it should be understood that the chassis 20 further includes a shell for enclosing the storage drive carriers 300, 300′ and 300″.
According to the above description, the present disclosure also provides a method for manufacturing the above storage drive carrier.
It should be appreciated that the example explanation and illustration of the specific shapes of the storage drive carrier do not constitute limitations over the composition and the structure of the present disclosure. Based on the teaching of the present disclosure, other shapes of storage drive carriers would be easily contemplated, simply by forming the protrusions for mutual engagement.
From the above description, protrusions for mutual engagement are constructed by shortening the circuit board within the storage drive carrier in the first direction D1, thereby saving the height of the storage drive carrier in the third direction D3. Thus, the chassis of the present disclosure may receive more storage drive carriers, so as to arrange the storage drive carriers more efficiently and meanwhile bring the advantages of lowering the possibility of space waste. Besides, to facilitate the production, the storage drive carrier 300 and the additional storage drive carrier 300′ described in the present disclosure have a completely identical shape.
It should be appreciated the above detailed embodiments of the present disclosure are provided only for illustrating or explaining the principles of the present disclosure by examples rather than restricting the present disclosure. Therefore, any amendments, equivalent substitutions, improvements and the like, as long as they are within the spirit and the scope of the present invention, should be included within the protection scope of the present invention. The present disclosure can more efficiently arrange the storage drive carriers and simultaneously lower the possibility of space waste.
