[0050] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a further detailed description of a hard disk tray of the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0051] Please refer to Figure 1-Figure 18 , a hard disk tray, comprising:

[0052] The tray assembly 100 has a hard disk 800 receiving slot 110;

[0053] The EMI shrapnel 600 is disposed at one end of the tray assembly 100;

[0054] The hard disk middle frame 200 is connected to the tray assembly 100 and sandwiches the EMI shrapnel 600 with the tray assembly 100;

[0055] The hard disk wrench 400 is arranged on a side of the hard disk middle frame 200 facing away from the EMI shrapnel 600. One end of the hard disk wrench 400 is hinged to the hard disk middle frame 200, and the other end is snap-connected to the hard disk middle frame 200. The hard disk wrench 400 is provided with a first snap-connecting portion 410. The hard disk middle frame 200 has a connecting groove 210 for accommodating the first snap-connecting portion 410. A second snap-connecting portion 300 snap-matched with the first snap-connecting portion 410 is provided in the connecting groove 210.

[0056] The wrench unlocking assembly 500 includes a button 510 and a return spring 520. When the button 510 is moved by an external force, it pushes the second buckle part 300 to separate from the first buckle part 410, and the return spring 520 generates a restoring force.

[0057] The hard disk wrench 400 is equipped with a wrench unlocking assembly 500, and the second buckle part 300 is separated from the first buckle part 410 by pressing the button 510, and the unlocking is convenient and simple. The button 510 is equipped with a return spring 520, which can automatically reset to ensure smooth operation next time.

[0058] Please refer to Figure 5 A rotation limit structure formed by a baffle and a stop groove 220 is provided between the hard disk wrench 400 and the hard disk middle frame 200. That is, the opening angle of the hard disk wrench 400 is limited. Preferably, the rotation angle is limited to 40-70°, and particularly, 52°. The rotation limit is designed to prevent the wrench from being stuck during rotation, thereby avoiding damage to the wrench and the hard disk middle frame 200.

[0059] Please refer to Figure 6-Figure 8 and Fig.18 , the second buckle part 300 is hinged with the hard disk middle frame 200 and is provided with a convex part 310, and the end of the button 510 away from the first buckle part 410 is hinged with the hard disk middle frame 200, and the other end is provided with a convex contact 511 that cooperates with the convex part 310. The convex part 310 and the convex contact 511 are provided to facilitate the contact between the button 510 and the second buckle part 300. The two ends of the rotating shaft 512 of the button 510 are provided with chamfers, and the two ends of the rotating shaft 512 are sleeved with gaskets 513. The chamfers facilitate the rotation shaft 512 of the button 510 to be inserted into the rotation shaft hole of the hard disk middle frame 200; gaskets 513 are added above and below the mounting surface of the rotating shaft 512 and the hard disk middle frame 200 to prevent the inner side wall where the button 510 is embedded from colliding or interfering with the inner side wall of the hard disk middle frame 200 when the button 510 is opened and closed.

[0060] Please refer to Figure 3-Figure 8The second buckle part 300 is hinged to the hard disk middle frame 200, and a torsion spring 322 is connected to the second buckle part 300. When the second buckle part 300 is separated from the first buckle part 410, the torsion spring 322 has a restoring force. To facilitate the automatic return of the rotating shaft 411 and ensure stable cooperation with the first buckle part 410, in particular, the torsion spring 322 always has a restoring force to make the second buckle part 300 approach the first buckle part 410, or, it can also just make the second buckle part 300 cooperate with the first buckle part 410. In particular, the first buckle part 410 and the second buckle part 300 both have a guide surface, usually, the guide surface is an inclined surface, so that when the guide surface of the first buckle part 410 contacts the guide surface of the second buckle part 300, the second buckle part 300 retreats, so that the first buckle part 410 and the second buckle part 300 are buckled.

[0061] In particular, please refer to Fig.18 , both ends of the hinge shaft 320 of the second buckle part 300 are provided with chamfers, and both ends of the hinge shaft 320 are sleeved with gaskets 321. The chamfers facilitate the hinge shaft 320 of the second buckle part 300 to be inserted into the buckle shaft hole of the middle frame button 510; gaskets 321 are added above and below the mounting surface of the hinge shaft 320 and the hard disk middle frame 200 to prevent the inner side wall of the second buckle part 300 from colliding or interfering with the inner side wall of the hard disk middle frame 200 when the second buckle part 300 is opened and closed.

[0062] Please refer to Fig.16 and Fig.17 , a guide protrusion 211 is further provided in the connection groove 210, and the guide protrusion 211 is located on both sides of the first buckle part 410. The guide protrusion 211 is provided to prevent the side wall of the hook inside the wrench from colliding or interfering with the inner side wall of the middle frame when the wrench is closed. Through the guide protrusion 211, when the hard disk wrench 400 is closed, the side wall of the first buckle part 410 of the hard disk wrench 400 is guided by the guide protrusion 211 on the inner side wall of the connection groove 210, which effectively prevents the side wall of the hook inside the hard disk wrench 400 from colliding or interfering with the inner side wall of the hard disk middle frame 200, and prevents the button 510 from being stuck or damaged due to excessive force. Preferably, the thickness of the guide protrusion 211 gradually increases inwardly, and the width of the first buckle part 410 gradually decreases toward the hard disk middle frame 200.

[0063] Please refer to Figure 3-Figure 8A compression spring 440 is provided between the hard disk wrench 400 and the hard disk middle frame 200. The compression spring 440 has a restoring force when the first buckle part 410 and the second buckle part 300 are buckled together. The compression spring 440 is provided so that when the hard disk wrench 400 is closed (i.e., when the first buckle part 410 and the second buckle part 300 are buckled together), the hard disk wrench 400 will not loosen. When unlocking is required, the button 510 is pressed to completely separate the first buckle part 410 and the second buckle part 300. The button 510 automatically returns to its original position under the action of the return spring 520, and the hard disk wrench 400 automatically pops out under the action of the compression spring 440.

[0064] Please refer to Figure 5-Figure 8 The button 510 has a cap body 514 protruding from the hard disk middle frame 200. The hard disk middle frame 200 is provided with a floating height limiting protrusion 230. The end of the cap body 514 away from the hard disk wrench 400 is in contact with the floating height limiting protrusion 230. This prevents the button 510 from floating and avoids the key jamming phenomenon. At the same time, the contact surface area of ​​the button 510 is increased. The finger pressing the button 510 will not cause pain, which meets the requirements of ergonomics. The floating button 510 does not require high manufacturing precision and is easy to assemble, which improves assembly efficiency and reduces manufacturing costs.

[0065] Please refer to Figure 2 , Figure 4 and Figure 5 The end of the hard disk wrench 400 away from the second buckle portion 300 is provided with an auxiliary extraction protrusion 420 and an auxiliary push protrusion 430. It is convenient to extract and push the hard disk wrench 400. Preferably, the baffle is served by the auxiliary extraction protrusion 420, and when it is rotated to a certain angle, the auxiliary extraction protrusion 420 abuts against the hard disk middle frame 200 to limit the rotation angle.

[0066] Please refer to Figure 4 and Fig. 9, an arc-shaped elastic arm 610 is provided at one end of the EMI shrapnel 600 away from the button 510 assembly, and the arc-shaped elastic arm 610 spans the internal serrations of the EMI shrapnel 600. The tray assembly 100 and the hard disk middle frame 200 have an avoidance groove for the arc-shaped elastic arm 610 to be exposed, and the tray assembly 100 and the hard disk middle frame 200 have a limiting portion 120 extending into the inner circle of the arc-shaped elastic arm 610 in the avoidance groove. The EMI shrapnel 600 on the left side of the hard disk 800 tray adopts a semi-circular arc-shaped arc-shaped elastic arm 610, which penetrates the serrated design, completely penetrates and covers the left side of the auxiliary puller, effectively protecting the left side section of all hard disk 800 trays in the chassis from electromagnetic leakage or reducing the risk of electromagnetic leakage on the left side of the hard disk 800 tray. The arc-shaped elastic arm 610 is buckled by the limiting portion 120 to prevent the hard disk 800 tray EMI shrapnel 600 from rubbing against the guide rail when inserting or removing the chassis and causing the risk of warping, deformation, and damage. Preferably, a triangular spring arm 620 is provided at one end of the EMI spring piece 600 close to the wrench unlocking assembly 500, that is, the shapes of the left and right spring arms are different.

[0067] Please refer to Figure 3-Figure 5 and Fig.10 , and also includes a primary light guide column 710, which passes through the tray assembly 100 and the EMI shrapnel 600 and extends into the hard disk middle frame 200, and the primary light guide column 710 corresponds to the indicator light of the hard disk 800. The hard disk wrench 400 is provided with a secondary light guide column 720, and the secondary light guide column 720 corresponds to the primary light guide column 710. The two-stage light guide column is set to guide light to the surface of the hard disk wrench 400, which is convenient for users to observe the status of the indicator light of the hard disk 800. Users can observe the status of the indicator light of the hard disk 800 not only from a straight-view angle, but also from an oblique angle, which is convenient for maintenance personnel to check the server operation status by observing the indicator light in the computer room.

[0068] Please refer to Figure 2 , Figure 3 and Fig.10 The primary light guide column 710 includes a first column 711, a second column 712 and a mounting seat 713. The first column 711 and the second column 712 are arranged on the mounting seat 713 at intervals. The mounting seat 713 is provided with at least two hooks 714, and the hard disk middle frame 200 is provided with buckle holes 240 corresponding to the hooks 714. The mounting seat 713 separates the first column 711 and the second column 712, which effectively prevents the two light sources from collided; it is fixed by buckles instead of directly embedded, and the chassis will not loosen when it vibrates at high or low frequencies, and the assembly is convenient and the structure is reliable.

[0069] Please refer to Fig.11, the secondary light guide column 720 is fixed on the hard disk wrench 400 by hot melting. Simply, after aligning the mounting hole of the secondary light guide column 720 with the four hot melt adhesive columns of the hard disk wrench 400, the four hot melt columns on the hard disk wrench 400 are heated, and the secondary light guide column 720 is hot melted on the hard disk wrench 400. The assembly is convenient, the assembly cost is low, and the structure is reliable. When the chassis vibrates at high or low frequencies, the secondary light guide column 720 will not loosen.

[0070] Please refer to Fig.12 and Fig.13 The two ends of the rotating shaft 411 of the hard disk wrench 400 have chamfered angles, and both ends of the rotating shaft 411 are sleeved with gaskets 513412321. The chamfered angles can facilitate the wrench shaft to be inserted into the wrench shaft hole of the middle frame; the gasket 513412321 can prevent the side wall of the inner hook of the wrench from colliding or interfering with the inner wall of the middle frame when the wrench is opened and closed.

[0071] Please refer to Fig.11 In particular, a limit baffle 450 is provided at one end of the hard disk wrench 400 away from the rotating shaft 411 , and the limit baffle 450 abuts against the end surface of the hard disk middle frame 200 to prevent the hard disk wrench 400 from excessively sinking into the hard disk middle frame 200 .

[0072] Please refer to Figure 5-Figure 8 Preferably, there is a safety gap between the button 510 and the convex part 310 in the unpressed state. When pressed, the button 510 rotates and then contacts the convex part 310. Continuous rotation completely contacts the convex part 310 to drive the second buckle part 300 to rotate, so that the second buckle part 300 is separated from the first buckle part 410. In particular, when the button 510 rotates to an angle of 7.5 degrees, the button 510 contacts the convex part 310. When the button 510 rotates to an angle of 12.5 degrees, the first buckle part 410 is completely separated from the second buckle part 300. This structure effectively avoids the problem that the tray is automatically popped open due to the short stroke of the button 510 and the button 510 is accidentally touched, thereby avoiding the problem that the high-frequency vibration of the chassis caused by the high-speed operation of the server fan causes the hard disk 800 gold finger (EMI shrapnel 600) to be loosened from the backplane connector, thereby causing the server system data to be lost.

[0073] It can be understood that one of the first buckle portion 410 and the second buckle portion 300 can be a hook and the other a ring, or one of them can be a hook and the other a matching hook.

[0074] Generally, the hard disk middle frame 200 and the tray assembly 100 are connected by screws, and the EMI shrapnel 600 is connected as a whole. In particular, the EMI shrapnel 600 can also be connected to the hard disk middle frame 200 and / or the tray assembly 100 by buckles.

[0075] This solution is not limited to E3.S1T, but also includes E3.S1T 1C, E3.S1T 2X1C, E3.S1T 2C, E3.S1T 4C, E3.S1T 4C+, E3.S2T, E3.S2T 1C, E3.S2T 2X1C, E3.S2T 2C, E3.S2T 4C, and E3.S2T 4C+.

[0076] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).
