Abstract

The invention discloses a server, which comprises a bearing chassis and a hard disk module. The bearing chassis comprises a bearing plate and side walls, wherein the side walls are arranged on two sides of the bearing plate and are respectively provided with a pivot. The hard disk module comprises a hard disk module shell, a first pivoting handle, a second pivoting handle and a fixer. The hard disk module shell is provided with a hard disk taking and placing opening. The first pivoting handle is pivoted with the hard disk module shell and detachably buckled on the pivot. The second pivot handle is pivoted on the hard disk module shell so that the hard disk module shell pivots relative to the bearing chassis by taking the pivot as a rotating shaft, thereby changing the pick-and-place included angle of the hard disk pick-and-place opening relative to the bearing plate. The fixer comprises a main body part and a column body, and when the second pivoting handle rotates to enable the hard disk taking and placing opening to be relatively far away from the bearing plate, the column body is telescopically inserted into the through hole of the second pivoting handle to maintain the included angle of taking and placing.

Description

Server

Technical Field

The invention relates to a server, in particular to a server with a pivotable handle.

Background

Servers often need to load a large number of hard disks at the same time to increase the storage capacity of information. In order to effectively utilize the space inside the server at the same time, the hard disk module for mounting the hard disk and the adjacent hard disk module or the electronic components around the hard disk module need to be designed in a close arrangement state. However, such a compact arrangement is not conducive to hard disk maintenance work.

The traditional method is that the whole bearing chassis bearing the hard disk module is taken out from the chassis, and then the hard disk therein can be taken out or the original hard disk can be replaced, but the bearing chassis is heavy in weight and is not beneficial to the operation of hard disk maintenance of operators or maintenance personnel, and even under the condition that the hard disk module is fully loaded with the hard disk, the bearing chassis is not easy to be taken out by a single person to complete the maintenance operation, and the bearing chassis is difficult to be placed and positioned correctly.

Disclosure of Invention

Therefore, the invention provides a server, which can solve the problem that the traditional server is inconvenient to maintain the hard disk and the like.

The server disclosed by the invention comprises a bearing chassis and at least one hard disk module. The bearing chassis comprises a bearing plate and two side walls, the side walls are respectively arranged on two opposite sides of the bearing plate, and the two side walls are respectively provided with a pivot. The hard disk module comprises a hard disk module shell, a first pivoting handle, a second pivoting handle and a fixer. The hard disk module shell is provided with a hard disk taking and placing opening. The first pivoting handle is pivoted with one side of the hard disk module shell, which is far away from the hard disk taking and placing opening, and detachably hooked on the pivot of the bearing chassis. The second pivot handle is pivoted on the hard disk module shell so that the hard disk module shell pivots relative to the bearing chassis by taking the pivot as a rotating shaft, and therefore a taking and placing included angle of the hard disk taking and placing opening relative to the bearing plate is changed. The fixer comprises a main body part and a column body, the main body part is arranged on the hard disk module shell, the column body is arranged on the main body part in a telescopic mode, and the second pivoting handle is provided with a through hole. When the second pivot handle rotates to make the hard disk taking and placing opening of the hard disk module shell relatively far away from the bearing plate, the column body is telescopically inserted into the through hole so as to maintain the taking and placing included angle between the hard disk taking and placing opening and the bearing plate through the second pivot handle

In the server disclosed by the invention, the hard disk module shell can be detachably pivoted on the bearing chassis through the first pivoting handle, and can be driven by the second pivoting handle to pivot relative to the bearing chassis and change the pick-and-place included angle of the hard disk pick-and-place opening relative to the bearing plate of the bearing chassis, namely the hard disk module shell can change the inclination degree of the hard disk module shell relative to the bearing plate through the driving of the second pivoting handle, so that the direction of the hard disk pick-and-place opening is changed. Therefore, when the hard disk is maintained, the hard disk module shell can be driven to a position suitable for taking and placing the hard disk only by rotating the second pivoting handle; when the hard disk module is taken out, the pin joint relation between the hard disk module shell and the bearing chassis can be released only by rotating the first pivot handle, and then the hard disk module can be directly taken out from the bearing chassis in a mode of holding the second pivot handle by one hand or holding the second pivot handle and the first pivot handle by two hands respectively. Therefore, by the server, the hard disk maintenance and the hard disk module taking-out operation can be carried out by only one person, and the bearing chassis does not need to be detached in the process, so that the operation efficiency and the convenience are improved.

In addition, when the hard disk module shell is driven by the first pivoting handle to incline, the second pivoting handle can be fixed by the fixer, so that the position of the hard disk module shell is indirectly maintained, namely, the picking and placing included angle between the hard disk picking and placing opening and the bearing plate is maintained, and the hard disk maintenance operation is facilitated.

The above description of the present invention and the following description of the embodiments are provided to illustrate and explain the spirit and principles of the present invention and to provide further explanation of the invention as claimed in the appended claims.

Referring to fig. 1-2, fig. 1 is a perspective view of a server according to an embodiment of the invention, and fig. 2 is an exploded view of the server of fig. 1. The present embodiment provides a server 1, which may include a carrying chassis 10 and at least one hard disk module 2. The hard disk module 2 is adapted to be received in a carrier chassis 10. In the preferred embodiment of the present invention, the number of the hard disk modules 2 that the server 1 can include depends on the design requirement, and the embodiment is suitable for when the hard disk modules 2 are not disposed at the near end and the far end of the server 1, but the present invention is not limited thereto.

The carrier chassis 10 includes a carrier plate 110 and two sidewalls 130. The two side walls 130 are respectively disposed on two opposite sides of the supporting plate 110 to surround a space capable of accommodating one or more hard disk modules 2 together with the supporting plate 110, which is not limited in the present invention. The carrier plate 110 and the sidewall 130 may be, but not limited to, an integrally formed structure. In addition, a step structure 131 is disposed on the inner side of each sidewall 130 for subsequent operation of the hard disk module 2, but the detailed description thereof will be described later.

In addition, in the present embodiment, a pivot 140 is further disposed on each of the inner surfaces of the two side walls 130. The pivot 140 is not limited to being integrally formed with the sidewall 130 or being otherwise fastened or welded to the sidewall 130. And the pivot 140 is between the step structure 131 and the carrier plate 110 when viewed from the opposite position.

Here, it should be noted that, other electronic components may be further disposed in the server 1 according to the requirement, but the invention is not limited thereto.

The following description will be made with respect to the hard disk module 2 and the part of the carrier chassis 10 related thereto. Referring to fig. 3A to 4, fig. 3A is a partially enlarged side view of the first pivot handle of fig. 1 disposed on the hard disk module housing, fig. 3B is a partially enlarged side view of the second pivot handle of fig. 1 disposed on the hard disk module housing, and fig. 4 is a perspective view of the second pivot handle of fig. 1.

In the present embodiment, the hard disk module 2 includes a hard disk module housing 20, a first pivot handle 30, two biasing members 40, and a second pivot handle 50.

The hard disk module housing 20 is adapted to be placed in the space surrounded by the carrying chassis 10, and is detachably pivoted to the pivot 140 on the carrying chassis 10, so as to be able to pivot about the pivot axis C1 relative to the carrying chassis 10. Further, in the present embodiment, the hard disk module housing 20 includes a bottom plate 210, a top plate 230, two side plates 250, and a plurality of partition plates 270. The two side plates 250 are respectively erected on two opposite sides of the bottom plate 210, and the top plate 230 is disposed on a side of the two side plates 250 facing away from the bottom plate 210, such that the two side plates 250 are interposed between the bottom plate 210 and the top plate 230. Thus, the bottom plate 210, the top plate 230 and the side plate 250 together enclose an accommodating space (not labeled). The partition 270 is disposed between the bottom plate 210, the top plate 230 and the side plate 250 to divide the accommodating space into a plurality of sub-spaces (not numbered).

In addition, the hard disk module housing 20 has a hard disk access opening 20a located at one side of the accommodating space and communicating with the sub-spaces, and a hard disk (not shown) can be placed into or taken out from the sub-spaces through the hard disk access opening 20a, but the invention is not limited by the number of the partition plates 270 (i.e. the number of the sub-spaces), the size of the sub-spaces, or the type and number of the hard disks that can be accommodated therein. In addition, in the present embodiment, the hard disk can be placed into the hard disk module casing 20 from the hard disk access opening 20a or taken out from the hard disk module casing 20 through the hard disk access opening 20a along an access direction P (as shown in fig. 6), where the access direction is a traveling direction when the hard disk is placed into the hard disk access opening 20a or taken out from the hard disk access opening 20a, and in principle, the access direction is, for example, horizontal to a long side direction of the side plate 250 of the hard disk module casing 20.

In addition, the other side of the side plate 250 away from the hard disk access opening 20a is respectively provided with a pivot slot 250a, the side plate 250 can be pivoted on the pivot 140 on the side wall 130 of the carrying chassis 10 through the pivot slot 250a, so that the hard disk module housing 20 can be pivoted relative to the carrying chassis 10 by the pivot axis C1 to be switched between a horizontal position (as shown in fig. 1) and a plugging position (as shown in subsequent fig. 6), but the pivot slot 250a can be optional, which is not limited herein. It is understood that the hard disk module housing 20 may further include other components or be additionally assembled with other components according to other requirements, but the invention is not limited thereto.

The first pivot handle 30 is pivotably provided on the hard disk module case 20. Specifically, in the present embodiment, the first pivoting handle 30 includes two first pivoting portions 310, two hooks 330 and a first cross portion 350. The two first pivoting portions 310 are respectively connected to two opposite sides of the first spanning portion 350, and the two hook portions 330 are respectively connected to one side of the first pivoting portion 310 away from the first spanning portion 350. The first cross portion 350 and the first pivot portion 310 and the hook portion 330 on both sides thereof are substantially perpendicular, so that the first pivot handle 30 is substantially in an inverted U shape. The two first pivoting portions 310 are respectively pivoted to the side plates 250 of the hard disk module housing 20, so that the first pivoting handle 30 can pivot relative to the hard disk module housing 20 by the pivot axis C2 to switch between a locking position (as shown in fig. 1) and a pushed position (as shown in fig. 5A). The hook 330 is disposed between the first pivot 310 and the supporting board 110 of the supporting chassis 10, and can be correspondingly fastened to the pivot 140 on the side wall 130 of the supporting chassis 10.

In the embodiment, the biasing member 40 is, for example, a compression spring, engaged between the first pivot handle 30 and the side plate 250 of the hard disk module casing 20, and can normally apply a biasing force (i.e., an elastic force) to the first pivot handle 30 to drive the hook portion 330 of the first pivot handle 30 to pivot toward the pivot 140 on the load-bearing chassis 10, i.e., the biasing member 40 can normally drive the first pivot handle 30 to pivot toward the snap-in position.

In addition, the hook portions 330 each have a pivot interface 30a, and the hook portions 330 are adapted to detachably hook to the pivot 140 via the pivot interfaces 30 a. Normally, when the first pivoting handle 30 is biased by the biasing member 40 to be located at the locking position, the pivoting opening 30a can communicate with the pivoting groove 250a of the side plate 250, so that the pivot 140 can simultaneously penetrate through the pivoting opening 30a of the hook 330 and the pivoting groove 250a of the side plate 250. The size of the hard disk pick-and-place opening of the pivot joint opening 30a is smaller than that of the pivot joint groove 250a, so that the pivot 140 will abut against the hook 330 and push the hook 330 away in the process of entering from the hard disk pick-and-place opening, and the purpose of the design can be explained in the following operation process. In addition, in the aforementioned case that the side plate of the hard disk module housing is optionally not provided with the pivot slot 250a, the hard disk module housing is detachably hooked on the pivot 140 only by the hook 330 of the first pivot handle 30.

The second pivot handle 50 is pivotally disposed on the top plate 230 of the hard disk module housing 20, and the whole position of the second pivot handle is between the hard disk access opening 20a of the hard disk module housing 20 and the first pivot handle 30. Further, in the present embodiment, the second pivot handle 50 includes two second pivot portions 510, two abutting portions 530, a second cross portion 550, a bending portion 570 and a block portion 590.

The second spanning portion 550 spans the top plate 230 of the hard disk module housing 20, and the two second pivot portions 510 are respectively connected to two opposite sides of the second spanning portion 550 and are respectively pivotally disposed on the side plates 250 of the hard disk module housing 20. The two abutting portions 530 are respectively located on a side of the second pivot portion 510 away from the second spanning portion 550 and extend in a direction away from the second spanning portion 550, and when viewed from opposite positions, the abutting portions 530 are located on a side of the second pivot portion 510 away from the hard disk access opening 20 a. The second cross portion 550 is substantially perpendicular to the second pivot portion 510 and the abutting portion 530 on both sides thereof, so that the second pivot handle 50 has a substantially inverted U-shape. Further, the two second pivoting portions 510 are respectively pivoted to the side plates 250 of the hard disk module housing 20 at pivot points 511, so that the second pivoting handle 50 is pivoted relative to the hard disk module housing 20 by the pivot axis C3 to switch between a lying position (fig. 1) and an inclined position (fig. 6). In addition, in the vertical direction (as viewed from the drawing), in the embodiment, the position of the step structure 131 of the side wall 130 of the supporting chassis 10 is between the pivot point 511 of the second pivot portion 510 (i.e., the position where the pivot axis C3 passes) and the supporting board 110; moreover, a vertical distance D1 from the pivot point 511 of the second pivot portion 510 to the step structure 131 of the sidewall 130 is smaller than a distance D2 from the pivot point 511 of the second pivot portion 510 to the end of the abutting portion 530.

The bending portion 570 extends outward from the second cross portion 550 toward a side of the first pivot handle 30, and forms an included angle (not numbered) with the second cross portion 550, that is, the bending portion 570 is a structure that is bent on a side of the second cross portion 550 relative to the second cross portion 550. The block 590 is disposed on the second cross portion 550, and the second pivot handle 50 has a through hole 590a penetrating through the second cross portion 550 and the block 590 therebehind, and the through hole 590a may correspond to the fastener 60.

And a holder 60 fixed to the top plate 230 of the hard disk module case 20 at a position adjacent to the through hole 590a of the second pivoting handle 50. Further, in the present embodiment, the holder 60 includes a main body 610, a switch 630 and a column 650. The cylinder 650 is telescopically inserted into the main body 610, and one end of the cylinder 650 is connected to the switch 630 and is controlled by the switch 630 to protrude out of or retract into the main body 610. When the switch 630 is turned off (as in the state shown in fig. 1, described above), the cylinder 650 is retracted into the body 610. When the switch 630 is turned on (as shown in the state shown in fig. 7, which follows), the column 650 protrudes from the body portion 610.

Next, operations of assembling the hard disk module 2, performing preparation before hard disk maintenance, removing the hard disk module 2, and the like will be described. First, please refer to fig. 5A-5C, which are flow charts of assembling the hard disk module of fig. 1.

When the hard disk module 2 is to be assembled, for example, the hard disk module 2 can be placed into the supporting chassis 10 in the direction a shown in the figure by holding the second pivoting handle 50, and the pivot 140 on the side wall 130 of the supporting chassis 10 is sleeved with the pivot groove 250a of the side plate 250 of the hard disk module housing 20 and the pivot opening 30a of the first pivoting handle 30.

At this time, as shown in fig. 5B, the pivot 140 first pushes the hook 330, or the hook 330 first pushes the pivot 140 and is pushed by the pivot 140, so that the first pivot handle 30 pivots in the direction B to switch from the latching position to the pushed position, so that the pivot 140 can enter the pivot opening 30a and the pivot groove 250a simultaneously. During the process, the biasing member 40 is pressed by the first pivot handle 30 to accumulate the elastic potential energy.

At this time, as shown in fig. 5C, after the pivot 140 enters the pivot interface 30a and the pivot slot 250a, the first pivot handle 30 can be driven by the biasing force (i.e. the accumulated elastic potential energy) of the biasing member 40 to automatically return to the latching position, so that the hook portion 330 latches the pivot 140, and the hard disk module casing 20 can be pivoted to the carrying chassis 10 by the first pivot handle 30. At this point, the other side of the hard disk module housing 20 may be lowered such that the hard disk module housing 20 may be placed in the load-bearing chassis 10 (i.e., as shown in fig. 1) with the pivot 140 as a pivot to rotate about the pivot axis C1 to complete the assembly of the hard disk module 2.

Next, referring to fig. 6 to 7, fig. 6 is an operation diagram of pivoting the hard disk module casing of fig. 5C from a horizontal position to a plugging position by operating the second pivot handle, and fig. 7 is an operation diagram of fixing the second pivot handle of fig. 6 at an inclined position by operating the fixing device. The preparation before the hard disk maintenance is performed will be described below.

First, as shown in fig. 6, the second pivot handle 50 may be pivoted in direction C to move the second pivot handle 50 from the bed flat position to the reclined position. In the process, the abutting portion 530 of the second pivot handle 50 abuts against the step structure 131 on the side wall 130 of the carrying chassis 10 and slides on the step structure 131 along with the rotation of the second pivot handle 50, and the step structure 131 is configured to limit the downward movement of the abutting portion 530, so that the second pivot handle 50 can lift the hard disk module housing 20 pivoted thereto upward (e.g. along direction D) when rotating, at this time, the hard disk module housing 20 can rotate relative to the carrying plate 110 of the carrying chassis 10 through the first pivot handle 30, thereby changing the inclination degree of the hard disk module housing 20 relative to the carrying plate 110, or changing the included angle θ between the hard disk taking and placing opening 20a and the carrying plate 110. The pick-and-place angle θ is an angle between the bottom plate 210 of the hard disk module housing 20 and the carrier plate 110 of the carrier chassis 10, and can be used to indicate the inclination degree of the hard disk pick-and-place opening 20a relative to the carrier plate 110. The hard disk module housing 20 is moved by the second pivot handle 50 until the bent portion 570 of the second pivot handle 50 abuts against the top plate 230 of the hard disk module housing 20 to stop the rotation of the second pivot handle 50. At this time, the pick-and-place direction P is inclined, the second pivot handle 50 reaches the set plugging position of the hard disk module housing 20, and at this time, the hard disk pick-and-place opening 20a of the hard disk module housing 20 is lifted to an angle suitable for allowing a maintenance worker or a worker to pick and place a hard disk in the hard disk module housing 20. In the embodiment, the pivot angle (i.e. the pick-and-place included angle θ) of the hard disk module housing 20 from the horizontal position (as shown in fig. 1) to the plugging position (as shown in fig. 6) is about 15 degrees, but the invention is not limited thereto.

Next, as shown in fig. 7, when the switch 630 of the holder 60 is opened in the direction "a" to maintain the hard disk module case 20 at the inserting and extracting position, the cylinder 650 in the main body 610 is driven to protrude outward from the main body 610 and to pass through the through hole 590a of the second pivot handle 50. At this time, the second pivot handle 50 is restricted by the retainer 60 to be maintained in the inclined position (i.e., not being able to rotate back to the lying position), so as to indirectly maintain the hard disk module housing 20 in the plugging position (as shown in fig. 6), thereby facilitating the subsequent hard disk maintenance operation. Conversely, it will be appreciated that after the hard disk maintenance operation or the hard disk installation operation is completed, the switch 630 of the holder 60 can be closed in the direction b opposite to the direction a to drive the column 650 to disengage from the through hole 590a of the second pivot handle 50 and retract into the main body 610, and at this time, the second pivot handle 50 can be pivoted back to the lying position in the direction opposite to the direction C, so as to reset the hard disk module casing 20 from the plugging position shown in fig. 6 to the horizontal position shown in fig. 1.

Next, referring to fig. 8, fig. 8 is a diagram illustrating an operation of taking out the hard disk module of fig. 7. If the hard disk module 2 is to be taken out from the carrying chassis 10, the first pivot handle 30 is pushed in the direction F to pivot the first pivot handle 30 to the pushed position, so that the hook 330 is separated from the pivot 140, and the connection relationship between the hard disk module housing 20 and the carrying chassis 10 via the first pivot handle 30 is released. At this time, the service person or the worker may take the hard disk module 2 out of the carrying chassis 10 by grasping the first pivoting handle 30 and the second pivoting handle 50 with two hands respectively, or may first grasp the second pivoting handle 50 with two hands respectively and rotate the first pivoting handle 30 to cancel the connection relationship of the first pivoting handle 30 fixed to the carrying chassis 10, and then take the hard disk module 2 by grasping the second pivoting handle 50 with one hand. It is to be understood that the hard disk module 2 can be easily taken out from the carrier chassis 10 by a serviceman or a worker directly from the state shown in fig. 1, for example, by grasping and rotating the first pivot handle 30 and the second pivot handle 50 with both hands, respectively.

In the server of the invention, the hard disk module shell can be detachably pivoted on the bearing chassis through the first pivoting handle, and can be driven by the second pivoting handle to pivot relative to the bearing chassis and change the pick-and-place included angle of the hard disk pick-and-place port relative to the bearing plate of the bearing chassis, that is, the hard disk module shell can change the inclination degree of the hard disk module shell relative to the bearing plate through the driving of the second pivoting handle, so that the direction of the hard disk pick-and-place port is changed. Therefore, when the hard disk is maintained, the hard disk module shell can be driven to a position suitable for taking and placing the hard disk only by rotating the second pivoting handle; when the hard disk module is taken out, the pin joint relation between the hard disk module shell and the bearing chassis can be released only by rotating the first pivot handle, and then the hard disk module can be directly taken out from the bearing chassis in a mode of holding the second pivot handle by one hand or holding the second pivot handle and the first pivot handle by two hands respectively. Therefore, by the server, the hard disk maintenance and the hard disk module taking-out operation can be carried out by only one person, and the bearing chassis does not need to be detached in the process, so that the operation efficiency and the convenience are improved.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
