Description

Retractable hard drive bay

The present invention relates to a hard disk carrier, and more particularly to a removable hard disk carrier.

In general, the server can store a large amount of information, and usually multiple hard disks are stored for storage. These hard disks are usually screwed to the server bracket. Whether installing or removing a hard disk requires an operator to use a hand tool, which is time consuming. The aforementioned problems will be more serious when the number of hard disks is large or the hard disk is replaced frequently. For this problem, the existing hard disk has been designed with a removable architecture. Generally speaking, it includes a hard disk case for accommodating a hard disk and a socket that can be quickly combined and separated from the hard disk case by using a hard disk. The structural characteristics of the disc case and the socket are quickly disassembled, which can save the time for the operator to replace the hard disk. However, it still takes time to install the hard disk into the box. If the installation is still carried out by screw locking, the design of the removable hard disk box is only to advance and delay the operation of locking and removing the screw; It takes a considerable amount of time to install the hard disk into the hard disk case, then join the hard disk case to the holder, and then remove the hard disk case from the holder to remove the hard disk from the hard disk case. In addition, a hard disk box is required for each hard disk, and even if the replaced hard disk needs to be placed in the hard disk case before being detached from the hard disk case, the cost of the accessory is increased.

In view of the problems in the prior art, the present invention provides a telescopic hard disk tray, the carrier of which is coupled with the chassis by a sliding mechanism, and the hard disk can be directly accommodated on the carrier or detached from the carrier, and the hard disk can be reduced. The operating time of the disc replacement and the cost of the accessories.

The telescopic hard disk tray includes a carrier, a first side sliding mechanism and a second side sliding mechanism. The carrier includes a first side wall and a second side wall opposite to the first side wall. The carrier forms an accommodating space, and a hard disk can be accommodated in the accommodating space. The first sliding mechanism includes a first sliding slot and a first guiding pillar. The first sliding slot extends along an extending direction and has a closed end in the extending direction. The first sliding slot and the first guiding slot The first sliding slot is disposed on the first side wall or the first side frame, and the first guiding column is correspondingly disposed on the first side frame or the first side wall. The second sliding mechanism includes a second sliding slot and a second guiding post. The second sliding slot is slidably connected to the second guiding post. The second sliding slot is disposed on the second sidewall or the second side frame. The second guiding post is correspondingly disposed on the second side frame or the second side wall. The carrier can slide into the storage space in a sliding direction through the first side sliding mechanism and the second side sliding mechanism, and the carrier is slid from the storage space in a direction opposite to the sliding direction. When sliding in the outbound direction, the first guiding column slides relative to the first sliding slot in the extending direction until the closed end blocks the first guiding post. Thereby, when the carrier slides out, the hard disk can be taken out from the carrier, and another replacement hard disk is loaded into the carrier, and the carrier is again slid into the storage space, that is, the hard is completed. The operation of the disc replacement.

Compared with the prior art, the carrier of the telescopic hard disk carrier of the present invention also adopts a sliding mechanism to facilitate the movement of the carrier relative to the chassis, so that there is still an advantage of reducing the operation time of the hard disk replacement. In addition, the carrier is not completely detached from the chassis and is shared, and it is not necessary to configure a carrier for each hard disk, so the cost of the accessory can be suppressed.

In this embodiment, the telescopic hard disk tray 1 further includes a spring arm 20 disposed on the second side wall 126 and having a protruding portion 202 protruding toward the accommodating space 128. The protrusion 202 is matched with one of the hard disk 4 locking holes 44, so that when the hard disk 4 is properly received in the accommodating space 128 and the carrier 12 is slid into the accommodating space 36, the elastic arm 20 can be squeezed by the second side frame 34. Pressing the protrusion 202 into the locking hole 44; in other words, if the hard disk 4 is not properly received in the accommodating space 128, the elastic arm 20 will not effectively lie flat against the second side wall 126, so that the second side frame 34 is stuck. The elastic arm 20, the carrier 12 cannot be completely slid into the storage space 36. Therefore, the protruding portion 202 of the elastic arm 20 has a foolproof function to prevent the hard disk 4 from being improperly mounted. In the present embodiment, the elastic arm 20 is integrally formed in a cantilever structure, for example, as a metal strip, and a cylinder is fixed (for example, riveted) as the protrusion 202. In this embodiment, the elastic arm 20 has a fixed end 204 and a free end 206. The fixed end 204 is fixed on the second side wall 126, the free end 206 protrudes outward from the second side wall 126, and the protruding portion 202 is located at the free end 206. . In addition, in the present embodiment, the elastic arm 20 is fixed to the outer side of the second side wall 126 and is located between the second side wall 126 and the second side frame 34, and is not limited thereto. For example, the fixed end 204 is fixed to the second side. The inner side of the two side walls 126, the free end 206 still protrudes from the second side wall 126 (for example, through the through hole of the second side wall 126), so that when the carrier 12 slides into the storage space 36, the free end 206 can be received by the second side frame 34. Extrusion to cause the protrusion 202 to enter the accommodating space 128, the structural configuration can still achieve the aforementioned foolproof function.

In addition, in the present embodiment, the elastic arm 20 is implemented by an additional cantilever member, and is not limited thereto in practice. For example, the elastic arm 20 is directly formed by one of the second side walls 126, that is, the elastic arm 20 is formed by bending and extending from the second side wall 126; in practice, the elastic arm 20 is integrally formed with the carrier 12. For example, the elastic arm 20 is configured as an arcuate structure, and one end is fixed to the second side wall 126, and the other end is slidably contacted with the second side wall 126. The protruding portion 202 is disposed at an intermediate portion of the arcuate structure and protrudes toward the accommodating space 128. This structure can also achieve the aforementioned foolproof function.

In addition, in the embodiment, the retractable hard disk tray 1 further includes a handle 22 and a holding member 24. The handle 22 has a pivoting portion 222, a hand-held portion 224 and a first protruding portion 226. The pivoting portion 222 is pivotally connected to the bottom plate 120 of the carrier 12, and the hand-held portion 224 and the first protruding portion 226 are connected to the pivoting connection. The portions 222 are located on opposite sides of the pivoting portion 222. The holding member 24 is disposed on the bottom plate 120 of the carrier 12 . In practice, the handle 22 is realized by a plastic injection member. Referring to FIG. 8, the first side frame 32 and the second side frame 34 are shown along the line X-X in FIG. When the carrier 12 slides toward the storage space 36 in the sliding direction D1, the handle 22 can be rotated toward the carrier 12 to hold the hand portion 224 to the holder 24 and the first protrusion 226 to the second side frame 34. One of the positioning holes 342 allows the carrier 12 to be held within the housing space 36. In practice, during the rotation of the handle 22 to the carrier 12, the first protrusion 226 can remain against the side wall of the positioning hole 342, so that the handle 22 can leverage to the first protrusion 226 and the positioning. The contact point of the hole 342 is a fulcrum, and the user applies a force to the hand-held portion 224, and the handle 22 pushes the carrier 12 with the pivoting portion 222 in the sliding direction D1; this also helps to completely slide the carrier 12 into the storage space 36. Internally (in practice, the connector 42 of the hard disk 4 is coupled to the connector 382 of the control circuit board 38).

In addition, in the embodiment, the holding member 24 includes a fixing portion 242 , a hook portion 244 and an elastic portion 246 .

When the holding member 24 holds the hand portion 224, the hook portion 244 hooks a structural edge of the hand portion 224 and the elastic portion 246 is elastically compressed by the hand portion 224. When the hook portion 244 is removed from the edge of the structure, the resilience generated by the compressed elastic portion 246 can push the handle 22 outwardly, so that the user can grasp the hand portion 224 to facilitate pulling out the carrier 12. . In addition, in the embodiment, the holding member 24 includes an operating portion 248 connected to the hook portion 244. When the hook portion 244 hooks the hand portion 224, the operating portion 248 can be operated (eg, the user moves the operating portion 248) to disengage the hook portion 244 from the hand portion 224 such that the compressed elastic portion 246 pushes the hand portion 224 The handle 22 is rotated away from the carrier 12. In addition, in the embodiment, the holding member 24 can be realized by a plastic injection member, which is not limited thereto. For example, the fixing portion 242, the hook portion 244, and the operating portion 248 are implemented as a single member (for example, a plastic injection member), and the elastic portion 246 is modified by a spring, and one end of the spring is fixed to the fixing portion 242, which can also The hand held portion 224 is compressed to generate a resilience.

In addition, please refer to FIG. 9, wherein the first side frame 32 and the second side frame 34 are shown along the line X-X in FIG. In the present embodiment, the handle 22 includes a second protrusion 228 that is coupled to the pivot portion 222 with respect to the hand portion 224. When the carrier 12 is received in the storage space 36, the operating portion 248 of the holding member 24 can be operated to disengage the hand portion 224 from the hook portion 244 of the holding member 24, so that the handle 22 can be rotated away from the carrier 12. So that the second protrusion 228 pushes against one of the structural side edges 344 of the second side frame 34 so that the carrier 12 slides in the sliding direction D2; wherein the handle 22 is leveraged, with the second protrusion 228 and the structure side The contact point of 344 is a fulcrum, the user applies force to the hand-held portion 224, and the handle 22 pulls the carrier 12 with the pivoting portion 222 in the sliding direction D2 (in practice, the connector 42 and the control for the hard disk 4 are included The connector 382 of the circuit board 38 is separated).

The connector 42 of the hard disk 4 is coupled to the connector of the control circuit board 38. If the hard disk 4 is not placed in the accommodating space 128 of the carrier 12 in the correct direction, the carrier 12 will not fully enter the storage space 36 through the foolproof function of the elastic arm 20, and the hard disk 4 can be avoided. The connector 42 or the connector of the control circuit board 38 is damaged by an unexpected collision. When the hard disk 4 on the carrier 12 needs to be taken out, the user can separate the holding member 24 from the handlebar 22, and operate the handlebar 22 to slide the carrier 12 out of the storage space 36 in the sliding direction D2. The user can then remove the hard disk 4 directly from the carrier 12 without the need for additional tools to remove the hard disk 4 from the carrier 12. After that, the user can put another hard disk into the accommodating space 128 of the carrier 12 to implement a hard disk replacement operation. Therefore, the original hard disk 4 and the subsequent hard disk need not be provided with individual hard disk frames or hard disk boxes, which can suppress the problem of increased cost of accessories in the prior art. Further, in the retractable hard disk tray 1 shown in this embodiment, whether the carrier 12 is slid into or out of the storage space 36, the handle 22 can be leveraged to provide a user's labor-saving operation. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
