Then, referring to
The hard disk drive chassis 20 includes a main body 30, a plurality of fasteners 40 and an engagement component 50.
The main body 30 includes a support plate part 31 and a stand plate part 32. The support plate part 31 includes a first plate portion 311, two second plate portions 312 and two third plate portions 313. The second plate portions 312 are connected to two opposite sides of the first plate portion 311, and the third plate portions 313 are respectively connected two sides of the second plate portions 312 away from the first plate portion 311; that is, the third plate portions 313 are connected to the first plate portion 311 respectively via the second plate portions 312. The third plate portions 313 are substantially parallel to the first plate portion 311 and are spaced apart from the first plate portion 311, and the first plate portion 311 and the second plate portions 312 together form a heat dissipation space 314 therebetween. The stand plate part 32 is connected to the first plate portion 311, and the stand plate part 32 and the second plate portions 312 are respectively located at different sides of the first plate portion 311.
The first plate portion 311 has a plurality of fastening structures 3111. The fastening structures 3111 are the same in structure. Each of the fastening structure 3111 is, for example, a through hole. The fastening structure 3111 has a narrow portion 3111a and a wide portion 3111b connected to each other. The wide portion 3111b has a width W4, and the narrow portion 3111a has a width W5, where the width W4 is larger than the width W5, and the width W2 of the wide portion 122 is smaller than the width W4 and is larger than width W5, and the width W1 of the narrow portion 121 is smaller than the width W5.
Each of the third plate portions 313 has a support surface 3131. The support surfaces 3131 substantially face the same direction and are configured to support the hard disk drive 2, and the fastening structures 3111 are located between the two support surfaces 3131. When the hard disk drive 2 is placed on the support surfaces 3131, air is allowed to flow through the heat dissipation space 314, formed by the first plate portion 311 and the second plate portions 312, for cooling the hard disk drive 2.
Each of the third plate portions 313 has a plurality of fixing structures 3132 formed on the support surface 3131. The fixing structures 3132 are, for example, through holes. The fixing structures 3132 of each third plate portion 313 are arranged from a side of the third plate portion 313 close to the stand plate part 32 toward a side of the third plate portion 313 away from the stand plate part 32; that is, on each third plate portion 313, the fixing structures 3132 are spaced by different distances from the stand plate part 32. In this embodiment, the fixing structures 3132 respectively correspond to screw holes of the hard disk drive 2 in different sizes. For example, two of the fixing structures 3132 located closest to the stand plate part 32 and another two of fixing structures 3132 located farthest away from the stand plate part 32 are configured for the screw holes of a hard disk drive of 3.5-inch, and four of the fixing structures 3132 located away from the stand plate part 32 are configured for the screw holes of a hard disk drive of 2.5-inch. In this embodiment, the hard disk drive 2 is, for example, in 3.5 inches, and the fasteners 40 are respectively configured to penetrate through the corresponding fixing structures 3132 and to be screwed into the screw holes of the hard disk drive 2.
In this embodiment, the stand plate part 32 has an outer surface 321, a guide block 322 and two positioning protrusions 323 and 324. The outer surface 321 and the support surfaces 3131 respectively face different directions. In detail, the outer surface 321 faces toward a direction which is substantially perpendicular to that the support surfaces 3131 face toward. When the hard disk drive 2 is placed on the support surfaces 3131, the outer surface 321 faces away from the hard disk drive 2. The guide block 322 and the positioning protrusions 323 and 324 are disposed on the outer surface 321, and the positioning protrusion 323 is located closer to the guide block 322 than the positioning protrusion 324.
The engagement component 50 includes a mount portion 51, an engagement portion 52 and a handle portion 53. The engagement portion 52 and the handle portion 53 are respectively connected to two adjacent sides of the mount portion 51, and the mount portion 51 is pivotably disposed on the outer surface 321 of the stand plate part 32. The mount portion 51 has a groove 511, a first end surface 512, a second end surface 513, a first positioning hole 514, a second positioning hole 515 and a recess 516. The groove 511 is, for example, in a curved shape. The first end surface 512 and the second end surface 513 are located at two opposite ends of the groove 511. The guide block 322 of the stand plate part 32 is slidably located in the groove 511 of the mount portion 51. The first positioning hole 514 and the second positioning hole 515 are respectively located close to the first end surface 512 and the second end surface 513, and the first positioning hole 514 and the second positioning hole 515 are respectively located farther away from an axis P of the mount portion 51 than the first end surface 512 and the second end surface 513. The recess 516 is located closer to the engagement portion 52 than the groove 511, the first positioning hole 514 and the second positioning hole 515. In this embodiment, the engagement component 50 is pivotable between an engaged position and a released position.
For the purpose of illustration, a Cartesian coordinate system is provided. Define that a normal line of the outer surface 321 of the stand plate part 32 is substantially parallel to X-axis, and normal lines of the support surfaces 3131 are substantially parallel to Z-axis.
Then, referring to
Firstly, the engagement component 50 is in the released position. At this moment, the guide block 322 is in contact with the second end surface 513, the positioning protrusions 323 and 324 are respectively located in the second positioning hole 515 and the recess 516. Then, the main body 30 is placed on the plate part 11 of the tray 10, and the wide portions 122 of the fastening parts 12 of the tray 10 respectively penetrate through the wide portions 3111b of the fastening structures 3111 of the first plate portion 311, and the positioning pillars 13 of the tray 10 are respectively in contact with sides of the second plate portions 312 facing away from the heat dissipation space 314. By doing so, the positioning pillars 13 limit the movements of the hard disk drive chassis 20 in the positive and negative Y-axis directions.
Then, referring to
The hard disk drive chassis 20 is moved along the negative X-axis direction, such that the narrow portions 121 of the fastening parts 12 of the tray 10 are respective moved to the narrow portions 3111a of the fastening structures 3111 of the first plate portion 311, and the extension portions 123 of the fastening parts 12 contact the first plate portion 311, such that the first plate portion 311 of the support plate part 31 is located between and clamped by the wide portions 122 of the fastening parts 12 and the plate part 11 of the tray 10. By doing so, the wide portions of the fastening parts 12 and the plate part 11 of the tray 10 together limit the movements of the hard disk drive chassis 20 in the positive and negative Z-axis directions.
Then, the engagement component 50 is pivoted toward the engaged position by applying force on the handle portion 53. When the engagement component 50 reaches the engaged position, different sides of the engagement portion 52 of the engagement component 50 contact the first stopping surface 141 and the second stopping surface 142 of the stopper 14, the guide block 322 is moved to the first end surface 512, and the positioning protrusions 323 and 324 are respectively located at the first positioning hole 514 and the second positioning hole 515. By doing so, the extension portions 123 of the fastening parts 12 and the first stopping surface 141 of the stopper 14 together limit the movements of the hard disk drive chassis 20 in the positive and negative X-axis directions. As a result, the movements of hard disk drive chassis 20 in X, Y and Z axis are limited, such that the hard disk drive chassis 20 is firmly engaged with and installed on the tray 10.
In this embodiment, when the engagement component 50 is pivoted toward the engaged position under a condition that the hard disk drive chassis 20 has been moved along the X-direction but not contact the extension portions 123 of the fastening parts 12, the engagement portion 52 of the engagement component 50 will contact the guide surface 143 of the stopper 14, such that the entire hard disk drive chassis 20 can be guided and moved in position along the negative X-axis direction. As such, it ensures that the engagement portion 52 of the engagement component 50 is in contact with the first stopping surface 141 and the second stopping surface 142 after the engagement component 50 is moved to the engaged position.
Then, performing the following steps can detach the hard disk drive chassis 20 from the tray 10: firstly, to pivot the engagement component 50 from the engaged position back to the released position so as to disengage the engagement portion 52 of the engagement component 50 from the stopper 140 of the tray 10; secondly, to move the hard disk drive chassis 20 along the positive X-axis direction so as to move the wide portions 122 of the fastening parts 12 of the tray 10 to the wide portions 3111b of the fastening structures 3111 of the first plate portion 311. By doing so, the hard disk drive chassis 20 is allowed to be detached from the tray 10 along the positive Z-axis direction.
In this embodiment, the support surfaces 3131 face the same direction, such that the support surfaces 3131 together support the bottom side of the hard disk drive 2 rather than two opposite lateral sides of the hard disk drive 2. Therefore, the hard disk drive chassis 20 does not require any lateral wall to support the lateral sides of the hard disk drive 2, such that the room between two adjacent hard disk drive chasses 20 is sufficient and thus allowing cables to be easily arranged.
In addition, the cooperation of the groove 511 and the guide block 322 can limit the movement range of the engagement component 50 so as to prevent the engagement component 50 from being overly pivoted. In this embodiment, the stand plate part 32 has the guide block 322, and the mount portion 51 of the engagement component 50 has the groove 511, but the present disclosure is not limited thereto; in some other embodiments, the stand plate part may have the groove, and the mount portion of the engagement component may have the guide block; in another embodiment, the stand plate part may have no guide block, and the mount portion of the engagement component may have no groove.
Moreover, the second stopping surface 142 is able to stop the engagement component 50 at the engaged position, which ensures that the engagement component 50 is positioned in the engaged position.
Furthermore, the cooperation of the positioning protrusions 323 and 324, the first positioning hole 514, the second positioning hole 515 and the recess 516 helps the engagement component 50 to be positioned in the engaged position or in the released position, such that the possibility of unexpected movement of the engagement component 50 can be reduced.
In this embodiment, the positioning protrusion 324 can enter into the recess 516 when the engagement component 50 is pivoted from the engaged position to released position, such the protrusion is prevented from interfering with the mount portion 51.
In this embodiment, the quantity of the positioning protrusions 323 and 324 is not restricted to be two; in some other embodiments, the stand plate part 32 may have only one positioning protrusion. For example, the stand plate part may mere have the positioning protrusion 323 shown in
The positions of the first positioning hole 514 and the second positioning hole 515 is not restricted; in some other embodiments, the first end surface and the second end surface of the groove may be located farther away from the axis of the mount portion than the first positioning hole and the second positioning hole.
In addition, each fastening part 12 of the tray 10 has the extension portion 123, but the present disclosure is not limited thereto; in some other embodiments, each fastening part of the tray may have no extension portion.
According to the hard disk drive chassis and the hard disk drive chassis assembly as discussed above, the support surfaces face the same direction, such that the support surfaces together support the bottom side of the hard disk drive rather than two opposite lateral sides of the hard disk drive. Therefore, the hard disk drive chassis does not require any lateral wall to support the lateral sides of the hard disk drive, such that the room between two adjacent hard disk drive chassis is sufficient and thus allowing cables to be easily arranged.
The embodiments were chosen and described in order to best explain the principles of the disclosure and its practical applications, to thereby enable others skilled in the art to best utilize the disclosure and various embodiments with various modifications as are suited to the particular use contemplated.
