Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

A server or other storage device usually includes a Just a Bunch Of Disks (JBOD), and the Bunch Of Disks includes a motherboard and a plurality Of hard Disks, the motherboard is installed in a cabinet, and each hard disk is installed on a rail Of the cabinet through a hard disk bracket.

In order to solve the above technical problem, an embodiment of the present application provides a hard disk tray, where the hard disk tray is applied to a cabinet. Fig. 1 is a schematic structural diagram of an opened state of the hard disk tray, and referring to fig. 1, the hard disk tray includes a frame 1 and a conductive member 2.

The frame body 1 includes a frame 11 and a movable plate 12, the frame 11 has a long-strip-shaped opening a, the movable plate 12 includes a first end and a second end in a length direction, the first end of the movable plate 12 is located at one end of the opening a in the length direction and is pivotally connected to the frame 11, the second end of the movable plate 12 is located at the other end of the opening a in the length direction and is detachably connected to the frame 11, and an accommodating space B for accommodating a hard disk is formed between the movable plate 12 and the frame 11. The conductive assembly 2 is connected with the frame 1, and a part of the conductive assembly is located in the accommodating space B and is used for contacting with the hard disk, and the other part of the conductive assembly is located outside the accommodating space B and is used for contacting with the cabinet.

When the hard disk bracket provided by the embodiment of the present application is used to mount a hard disk on a cabinet, the connection between the second end of the movable plate 12 and the frame 11 is released, and the movable plate 12 is rotated around the pivot axis between the first end of the movable plate 12 and the frame 11, so that the opening a on the frame 11 is opened, and a passage is provided for the hard disk to enter the accommodating space B (see fig. 1). After the hard disk is placed in the accommodating space B, the movable plate 12 is rotated in a reverse direction about the pivot axis between the first end of the movable plate 12 and the frame 11, and the second end of the movable plate 12 is connected to the frame 11 again, so that the opening a of the frame 11 is closed, and the hard disk is enclosed in the accommodating space B (see fig. 2). Thus, the installation between the hard disk bracket and the hard disk is completed.

When the hard disk is plugged into the cabinet along with the hard disk bracket, one part of the conductive component 2 is positioned in the accommodating space B and is in contact with the hard disk, and the other part of the conductive component 2 is positioned outside the accommodating space B and is in contact with the cabinet, so that the hard disk is electrically connected with the cabinet through the conductive component 2. Once a little static charge is generated on the hard disk, the static charge can be released to the cabinet through the conductive component 2, and thus, the circuit failure of the disk cluster caused by the sudden release of a large amount of static charge from the hard disk can be avoided.

As can be seen from the foregoing, the conductive assembly 2 plays a key role in avoiding circuit failure of the disk cluster caused by sudden release of a large amount of static electricity from the hard disk, and the following description continues on the conductive assembly 2.

The conductive assembly 2 is located on the movable plate 12, and the movable plate 12 extends along the inserting and extracting direction of the hard disk bracket. So design, can be convenient for conductive component 2 and the guide rail contact of rack.

Fig. 3 is an exploded view of the conductive member 2, and a part of the frame body 1 is retained in fig. 3 in order to more clearly show the assembly relationship between the conductive member 2 and the frame body 1.

Referring to fig. 3, in the present embodiment, the conductive member 2 includes a conductive pin 21 and a conductive reed 22.

The conductive pin 21 is inserted into the frame 1, a first end of the conductive pin 21 is located in the accommodating space B to be clamped with the pin hole of the hard disk, and a second end of the conductive pin 21 is located outside the accommodating space B.

The first end of the conductive pin 21 is located in the accommodating space B, and when the hard disk is installed in place in the accommodating space B, the first end of the conductive pin 21 can be inserted into the pin hole of the hard disk. Because the pin control of the hard disk is positioned on the shell of the hard disk, the conductive pin 21 can realize the electrical connection with the shell of the hard disk and the clamping connection of the hard disk, and the installation stability of the hard disk in the frame body 1 is improved.

The conductive reed 22 is located outside the accommodating space B, the conductive reed 22 is connected to the frame 1 and the second end of the conductive pin 21, and a part of the conductive reed 22 protrudes away from the accommodating space B to contact with the cabinet.

Since the conductive reed 22 is in contact with the conductive pin 21 and the cabinet, respectively, the electric charge discharged from the hard disk to the conductive pin 21 can be further guided to the cabinet to be discharged through the cabinet. Moreover, since the conductive reed 22 has elasticity, the part protruding from the accommodating space B contacts with the cabinet, but in the process of inserting and pulling the hard disk bracket, the conductive reed 22 can generate self-adaptive elastic deformation, and the normal inserting and pulling of the hard disk bracket is not affected.

Optionally, the part of the conductive reed 22, which deviates from the protrusion of the accommodating space B, is in sliding contact with the guide rail of the cabinet, so that the design ensures not only the electrical connection between the conductive reed 22 and the cabinet, but also the smooth sliding of the hard disk bracket in the cabinet.

Illustratively, the conductive reed 22 is in a strip shape, a first end of the conductive reed 22 is connected to a second end of the conductive pin 21, the second end of the conductive reed 22 is inserted into the frame 1, and a portion between the first end and the second end of the conductive reed 22 protrudes away from the accommodating space B.

In the above embodiment, since the conductive pin 21 is inserted into the housing 1, the first end of the conductive reed 22 is connected to the conductive pin 21, and not only the electrical connection between the conductive reed 22 and the conductive pin 21 but also the indirect connection with the housing 1 can be realized. In addition, the second end of the conductive reed 22 is directly inserted into the frame 1, so that both ends of the conductive reed 22 are fixed, and the installation stability of the conductive reed 22 on the frame 1 is ensured. Moreover, since the part between the two ends of the conductive reed 22 protrudes, the part is not only ensured to be fully contacted with the cabinet, but also prevented from influencing the installation between the conductive reed 22 and the frame body 1.

Illustratively, the portion between the first end and the second end of the conductive reed 22 protruding away from the accommodating space B is arc-shaped, so that the portion can better make sliding contact with the guide rail of the cabinet.

In order to further improve the installation stability of the conductive assembly 2 on the frame 1, in the present embodiment, the conductive assembly 2 further includes a first pressing piece 23 and a second pressing piece 24.

The first pressing piece 23 is connected with the first end of the conductive reed 22 and is attached to the outer wall of the frame 1. The second pressing piece 24 is sleeved at the second end of the conductive pin 21 and attached to one side surface of the first pressing piece 23 departing from the frame body 1.

In the above embodiment, since the first presser 23 is attached to the outer wall of the housing 1, the contact area between the first end of the conductive reed 22 and the housing 1 can be increased, and the conductive reed 22 can be more stably attached to the housing 1. For the same reason, since the second pressing piece 24 is bonded to the first pressing piece 23, the second pressing piece 24 can press the first pressing piece 23 against the housing 1, and the mounting stability of the conductive member 2 on the housing 1 is ensured.

Illustratively, the first pressing piece 23 and the second pressing piece 24 are both conductors, so that the electrical connection between the conductive pin 21 and the conductive spring 22 can be further ensured, the problem of poor contact between the two is avoided, and the reliability of the conductive assembly 2 is improved.

Optionally, the conductive pin 21, the conductive spring 22, the first pressing piece 23 and the second pressing piece 24 are all copper structural members to ensure good conductivity.

Illustratively, the first pressing piece 23 and the second pressing piece 24 are both rectangular plate-shaped structural members, a first end of the conductive spring 22 is vertically connected to one side edge of the first pressing piece 23, and a second end of the conductive pin 21 is vertically connected to one side edge of the second pressing piece 24. The first presser piece 23 and the conductive spring 22 are an integral structure, and the second presser piece 24 and the conductive pin 21 are an integral structure. By the design, the structural integrity of the conductive component 2 is improved, the manufacturing and production efficiency of the conductive component 2 is improved, and the manufacturing and production cost of the conductive component 2 is reduced. Of course, in other embodiments, the first pressing piece 23 and the conductive spring piece 22, and the second pressing piece 24 and the conductive pin 21 can be independent parts, and are connected together by welding or the like, which is not limited in this application.

When the first pressing piece 23 and the second pressing piece 24 are bonded together, the orthographic projection of the first pressing piece 23 on the frame body 1 is positioned in the orthographic projection of the second pressing piece 24 on the frame body 1. By the design, the second pressing piece 24 can press the first pressing piece 23 on the frame body 1 completely.

In order to further improve the installation stability of the conductive assembly 2 on the frame 1, in the embodiment, the first pressing plate 23 and the second pressing plate 24 are both provided with rivet holes 25, the rivet holes 25 on the first pressing plate 23 and the rivet holes 25 on the second pressing plate 24 are opposite one to one, the same rivet 26 is respectively inserted into each group of opposite rivet holes 25, and the first pressing plate 23 and the second pressing plate 24 are riveted on the frame 1 through the rivet 26.

That is, the rivet 26 sequentially passes through the rivet hole 25 of the second pressing piece 24 and the rivet hole 25 of the first pressing piece 23, so that the second pressing piece 24 and the first pressing piece 23 are riveted together on the frame 1, and the second pressing piece 24 and the first pressing piece 23 are stably mounted on the frame 1.

Of course, in other embodiments, the first pressing piece 23 and the second pressing piece 24 can be mounted on the frame body 1 by other means, such as screws, pins, etc., which is not limited in this application.

Alternatively, the rivet holes 25 on the first pressing plate 23 are located at the outer edge of the first pressing plate 23, and the rivet holes 25 on the second pressing plate 24 are located at the outer edge of the second pressing plate 24. By the design, the whole first pressing piece 23 and the whole second pressing piece 24 can be tightly attached to the frame body 1, so that the connection stability of the first pressing piece 23 and the second pressing piece 24 on the frame body 1 is guaranteed.

In order to ensure that the first pressing piece 23 and the second pressing piece 24 can be accurately installed on the frame body 1, the frame body 1 further comprises a positioning pin 13. Locating pin 13 deviates from accommodation space B and extends, and first preforming 23 and second preforming 24 cup joint outside locating pin 13 respectively.

When installing first preforming 23 and second preforming 24, establish first preforming 23 and second preforming 24 on locating pin 13 in proper order, play the effect of preliminary location, then reuse rivet 26 with first preforming 23 and second preforming 24 riveting on framework 1 to guarantee the accurate installation of first preforming 23 and second preforming 24 on framework 1.

While the conductive assembly 2 provided in the embodiment of the present application has been described above, in other embodiments, the conductive pin 21 can be replaced with other conductive parts, such as a metal spring, a conductive foam, etc., only by electrically connecting the casing of the hard disk and the conductive spring 22.

In addition, in other embodiments, in order to simplify the structure of the hard disk tray, the frame body 1 is provided as a conductive plastic structure. By the design, the electrical connection between the shell of the hard disk and the guide rail of the cabinet can be directly realized through the frame body 1, and the function of timely releasing static charges on the hard disk can be realized. It will be readily appreciated that in this case, the conductive member 2 can be omitted.

Next, the frame 1 will be described.

Referring again to fig. 1, in the present embodiment, the frame 11 includes a first end plate 111, a second end plate 112, and a connecting plate 113. The first end plate 111 and the second end plate 112 are opposed and arranged parallel to each other, and the opening a is located between the first end of the first end plate 111 and the first end of the second end plate 112. The connecting plate 113 is located between the first end plate 111 and the second end plate 112, and a first end of the connecting plate 113 is connected to a second end of the first end plate 111, and a second end of the connecting plate 113 is connected to a second end of the second end plate 112.

In the above implementation, the first end plate 111, the connecting plate 113 and the second end plate 112 together form a semi-open frame structure with an opening a, and the opening a is used for providing a passage for the hard disk to enter the accommodating space B.

In the present embodiment, the movable plate 12 includes a baffle 121 and a catch 122. The first end of the baffle 121 is pivotally connected to the first end of the first end plate 111, and the second end of the baffle 121 is connected to the buckle 122. The inner side wall of the buckle 122 is attached to the outer side wall of the second end plate 112 and detachably connected.

In the above implementation, the shutter 121 rotates about the pivot axis between the first end of the shutter and the first end plate 111, thereby opening or closing the opening a. When the opening a needs to be closed, the buckle 122 rotates along with the rotation of the baffle 121, when the buckle 122 rotates to the second end plate 112, the opening a is closed by the baffle 121, and the inner side wall of the buckle 122 is attached to and connected with the outer side wall of the second end plate 112. When the opening a needs to be opened, the connection between the catch 122 and the second end plate 112 is released, and then the shutter 121 is rotated to open the opening a.

Fig. 4 is a schematic structural diagram of the clip 122, and in combination with fig. 4, exemplarily, an inner side wall of the clip 122 has a latch 123, an outer side wall of the second end plate 112 has a latch hole 114, and the latch hole 114 is used for latching the latch 123.

In the implementation manner, by using the slight elasticity of the connection between the baffle 121 and the clip 122, in the process of clipping the latch 123 into the clipping hole 114, the clip 122 can swing with a small amplitude relative to the baffle 121 to make room for the latch 123 to slide into the clipping hole 114, so that the latch 123 can be clipped into the clipping hole 114. Similarly, when the connection between the latch 122 and the second end plate 112 needs to be released, the latch 122 is pulled in a direction away from the second end plate 112, so that the latch 122 can swing to a small extent relative to the baffle 121 by virtue of the slight elasticity of the connection between the baffle 121 and the latch 122, and the latch 123 is disengaged from the latch hole 114.

Illustratively, the frame body 1 is a plastic structural member, so that the light weight design of the hard disk bracket is facilitated, and the manufacturing cost is reduced.

The above description is only exemplary of the present application and should not be taken as limiting, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
