[0003] With the rise of big data, cloud computing and AI (artificial intelligence), the storage capacity requirements of electronic devices are increasing.

[0004] An electronic device includes an electronic device housing, a hard drive located within the housing, and a hard drive backplane. The electronic device housing includes a front panel and a rear panel. The hard drive backplane is mounted within the electronic device housing, and the hard drive is plugged into the hard drive backplane via the front panel or rear panel of the electronic device housing. To replace or maintain a hard drive, the hard drive is removed from the hard drive backplane via the front panel or rear panel of the electronic device housing. To increase the storage capacity of the electronic device, a hard drive is also required to be located in the middle area of ​​the electronic device housing.

[0005] However, when a hard disk is disposed in the middle area of ​​the electronic device housing, the hard disk is difficult to install and disassemble, and the number of hard disks that can be installed in the electronic device is relatively small.

[0069] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0070] With the rise of big data, cloud computing and AI (artificial intelligence), the storage capacity requirements of electronic devices are increasing.

[0071] Figure 1 is a schematic diagram of the structure of an electronic device in the related art. The electronic devices in the related art are all represented by 1000n, and the components in the electronic device 1000n are also suffixed with "n" to distinguish them from the electronic devices provided in the embodiments of the present application.

[0072] As shown in FIG1 , the electronic device 1000n includes an electronic device housing 100n, a hard disk 200n located in the housing, and a hard disk backplane 300n.

[0073] The electronic device housing 100n includes a front panel 110n, a rear panel 120n, a bottom wall 130n and a side wall 140n. The electronic device housing 100n is a rectangular parallelepiped structure. The length direction of the electronic device housing 100n is a first direction X, the width direction of the electronic device housing 100n is a second direction Y, and the direction in which the height of the electronic device housing 100n extends is a height direction H.

[0074] The front panel 110n and the rear panel 120n are arranged relative to each other along a first direction X. The hard disk backplane 300n is installed in the electronic device housing 100n. The hard disk 200n is plugged into the hard disk backplane 300n via the front panel 110n or the rear panel 120n of the electronic device housing 100n (wherein, FIG. 1 only shows the hard disk 200n installed on one side of the front panel 110n). When a hard disk 200n needs to be replaced or maintained, the single hard disk 200n is removed from the hard disk backplane 300n via the front panel 110n or the rear panel 120n of the electronic device housing 100n.

[0075] In order to increase the storage capacity of the electronic device 1000n, a hard disk 200n needs to be provided in the middle area of ​​the electronic device housing 100n. Thus, more hard disks 200n can be installed in the limited space of the electronic device housing 100n.

[0076] FIG2 is a second structural diagram of an electronic device in the related art.

[0077] As shown in Figure 2, a hard drive backplane 300n is also provided in the middle area of ​​the electronic device housing 100n, on which multiple hard drives 200n are mounted. Specifically, the hard drives 200n are mounted in a hard drive fixture 400n and then connected to the hard drive backplane 300n and the bottom wall 130n of the electronic device housing 100n via the hard drive fixture 400n. The hard drives 220n also need to be electrically connected to the hard drive backplane 300n. However, when the hard drives 200n are mounted via the hard drive fixture 400n, they occupy a relatively large space within the electronic device housing 100, resulting in a smaller number of hard drives 200n in the electronic device 1000n.

[0078] Figure 3 is a schematic diagram of the assembled structure of a hard drive and a hard drive mounting device for an electronic device in the related art; Figure 4 is a schematic diagram of the exploded structure of the hard drive and hard drive mounting device for an electronic device in the related art. Referring to Figures 3 and 4 , the hard drive mounting device 400n includes a base 410n and a rotating window 420n. The rotating window 420n is disposed on one side of the base 410n along a first direction X and is rotatable relative to the base 410n.

[0079] The base 410n has a receiving cavity 411n. When the hard disk 200n needs to be installed on the electronic device housing 100n, the rotating window 420n of the hard disk fixing device 400n is first opened, the hard disk 200n is placed in the receiving cavity 411n, and then the rotating window 420n is fixed to the base 410n. The hard disk 200n has a connector 210n on the side opposite to the rotating window 420n along the first direction X.

[0080] The assembled hard drive 200n and hard drive fixture 400n are placed within the electronic device housing 100n. The hard drive 200n and hard drive fixture 400n are then moved toward the backplane 300n. The connector 210n of the hard drive 200n is plugged into the backplane 300n, thereby completing the installation of the hard drive 200n and the hard drive backplane 300n. Since the hard drive 200n needs to be moved along a first direction X during installation, the electronic device housing 100n requires a reserved operating area 150n for installing the hard drive 200n (the operating area 150n is indicated by a dashed box in FIG. 2 ). This reduces the number of hard drives 200n that can be installed along the first direction X. The rotating window 420n occupies space within the electronic device housing 100n along the first direction X, further reducing the number of hard drives 200n that can be installed within the electronic device housing 100n. In addition, the base 410n has a certain thickness, and therefore, the base 410n also occupies space in the electronic device housing 100n along the second direction Y, so that a smaller number of hard disks 200n can be installed along the first direction X. Therefore, a smaller number of hard disks 200n can be installed in the electronic device housing 100n.

[0081] The hard drive fixture 400n also includes a power-assisting handle 430n and an operating handle 440n connected thereto. The power-assisting handle 430n includes a protrusion 431n. The protrusion 431n and the operating handle 440n are located on either side of the base 410n along the height direction H. The power-assisting handle 430n is rotatable relative to the base 410n. When an operator pulls the operating handle 440n, friction is generated between the protrusion 431n and the bottom wall 130 of the electronic device housing 100n. This movement causes the assembly formed by the hard drive 200n and the hard drive fixture 400n to move in the first direction X, plugging the connector 210n of the hard drive 200n into the hard drive backplane 300n. This demonstrates that the installation method for the hard drive 200n is also relatively complex.

[0082] Based on this, an embodiment of the present application provides a hard disk module and an electronic device. The hard disk module is simple to install in the electronic device and occupies a small space in the electronic device.

[0083] Figure 5 is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application; Figure 6a is a schematic diagram of the relative positions of the partition plate, hard disk backplane, and hard disk module in the electronic device provided in an embodiment of the present application; and Figure 6b is a schematic diagram of the relative positions of the partition plate, hard disk backplane, and hard disk module in the electronic device provided in an embodiment of the present application from another angle. Figure 6b is a view from the back of Figure 6a.

[0084] As shown in Figures 5 to 6b, the electronic device 1000 includes an electronic device housing 100, multiple partitions 400 and multiple hard disk modules 500, the partitions 400 are arranged in the electronic device housing 100 at intervals along a first direction X, and multiple hard disk modules 500 are arranged between two adjacent partitions 400. The multiple hard disk modules 500 are arranged in sequence along a second direction Y, wherein the second direction Y is perpendicular to the first direction X.

[0085] The electronic device 1000 may be a server, a computer host or other controllers.

[0086] The electronic device housing 100 is a rectangular parallelepiped structure. The length direction of the electronic device housing 100 is a first direction X, the width direction of the electronic device housing 100 is a second direction Y, and the height direction H of the electronic device housing 100 is a height direction.

[0087] The plurality of partitions 400 are arranged in the electronic device housing 100 along the first direction X and extend along the second direction Y. Both ends of the partitions 400 are connected to the two side walls 140 of the electronic device housing 100 .

[0088] The partition 400 is provided with limiting plates 410 arranged at intervals along the second direction Y. A hard disk module 500 is provided between two adjacent limiting plates 410, and the limiting plates 410 separate the hard disk module 500 along the second direction Y. The partition 400 and the limiting plates 410 divide the space in the electronic device housing 100 into accommodating spaces 150, and these accommodating spaces 150 are arranged in a rectangular array in the electronic device housing 100. In other words, the hard disk module 500 can be limited in both the first direction X and the second direction Y by the partition 400 and the limiting plates 410. Among them, the two adjacent partitions 400 can be respectively referred to as the first partition 400a and the second partition 400b, and the first partition 400a and the second partition 400b are located on both sides of the hard disk module 500 along the first direction X.

[0089] The hard disk module 500 is inserted into the accommodating space 150 from above the electronic device housing 100. That is to say, the hard disk module 500 is also arranged in a rectangular array in the electronic device housing 100. Thus, the space in the electronic device housing 100 can be fully utilized, so that the electronic device housing 100 can accommodate more hard disk modules 500, thereby improving the storage capacity of the electronic device 1000.

[0090] Please continue to refer to Figures 6a and 6b. The electronic device 1000 also includes a hard disk backplane 300. The hard disk backplane 300 is located between the partition 400 and the bottom wall 130 of the electronic device housing 100 along the height direction H of the electronic device housing 100. A second connector 310 is provided on one side of the hard disk backplane 300. The hard disk module 500 has a first connector 510. The second connector 310 is used to be plugged into the first connector 510.

[0091] The hard drive backplane 300 can be mounted on the bottom wall 130 of the electronic device housing 100 or on the partition 400. Multiple hard drive backplanes 300 are also spaced apart along the first direction X and extend along the second direction Y. The hard drive backplane 300 has multiple second connectors 310. After the hard drive module 500 is inserted into the accommodating space 150, the first connectors 510 are plugged into the second connectors 310. In this embodiment, the first connectors 510 are pin headers, and the second connectors 310 are sockets.

[0092] Next, the installation method of the hard disk module 500 in the electronic device housing 100 is described.

[0093] Figure 7 is a structural schematic diagram of the hard disk module and the hard disk backplane provided in an embodiment of the present application installed together; Figure 8 is a structural schematic diagram of the hard disk module and the hard disk backplane provided in an embodiment of the present application separated, wherein Figures 7 and 8 also show two partitions 400 adjacent to the hard disk module, two hard disk backplanes 300 and the bottom wall 130 of the electronic device housing 100, so as to clearly illustrate the installation method of the hard disk module 500 in the electronic device housing 100.

[0094] 7 and 8 , the hard disk module 500 includes a first connector 510 (the first connector 510 is blocked by the hard disk body 520, so the first connector 510 is schematically shown in a filled dotted box in FIG7 and FIG8 ), a hard disk body 520 and a hard disk mounting assembly 530. The hard disk mounting assembly 530 and the first connector 510 are respectively arranged on two adjacent side edges of the hard disk body 520; the hard disk mounting assembly 530 includes a first eccentric wheel 531, a second eccentric wheel 532 and a fixing seat 533; the fixing seat 533 is connected to the hard disk body 520, the first eccentric wheel 531 and the second eccentric wheel 532 are arranged at opposite ends of the fixing seat 533 along a first direction X, and the first eccentric wheel 531 and the second eccentric wheel 532 are both hinged to the fixing seat 533. The hard disk mounting assembly 530 also includes a connecting rod 535, one end of the connecting rod 535 is hinged to the first eccentric wheel 531. The other end of the connecting rod 535 is hinged to the second eccentric wheel 532, wherein the second eccentric wheel 532 is located at one end of the first connector 510; when the hard disk module 500 is installed in the electronic device 1000, the first eccentric wheel 531 is used to abut against the first partition 400a of the electronic device 1000, and the first connector 510 is used to be plugged into the second connector 310 located on the side of the second partition 400b of the electronic device 1000; when the hard disk module 500 is removed from the electronic device 1000, the first eccentric wheel 531 is rotated, and the first eccentric wheel 531 drives the second eccentric wheel 532 to rotate through the connecting rod 535, and the second eccentric wheel 532 abuts against the second partition 400b to apply thrust on the second partition 400b, so that the hard disk module 500 moves along the first direction X toward the first partition 400a, thereby disconnecting the first connector 510 from the second connector 310.

[0095] Specifically, the hard disk body 520 has a rectangular structure and includes a first side 521, a second side 522, a third side 523, and a fourth side 524. The first side 521 and the third side 523 extend along a first direction X, and the second side 522 and the fourth side 524 extend along a height direction H. The lengths of the first side 521 and the third side 523 are greater than the lengths of the second side 522 and the fourth side 524.

[0096] The hard disk mounting assembly 530 can be disposed on the first side 521 , and the first connector 510 can be disposed on the second side 522 . When the hard disk module 500 is inserted into the receiving space 150 , the third side 523 abuts against the bottom wall 130 of the electronic device housing 100 .

[0097] The hard disk mounting assembly 530 is used to fix the hard disk module 500 on the partition 400. The specific structure of the hard disk mounting assembly 530 is described below.

[0098] FIG9 is a structural schematic diagram 1 of a hard disk installation assembly in a hard disk module provided in an embodiment of the present application; FIG10 is a structural schematic diagram of FIG9 from another angle.

[0099] 9 and 10 , the fixing base 533 includes a first fixing plate 5331 and a second fixing plate 5332 connected together. The first fixing plate 5331 and the second fixing plate 5332 are angled together. In this embodiment, the angle is 90°. The first fixing plate 5331 has a first mounting hole 5331a, and the first side 521 of the hard disk body 520 has a second mounting hole. Fasteners are inserted through the first mounting hole 5331a and the second mounting hole to connect the fixing base 533 to the hard disk body 520.

[0100] The first eccentric wheel 531 and the second eccentric wheel 532 are both hingedly connected to the second fixing plate 5332. Therefore, the first eccentric wheel 531 and the second eccentric wheel 532 can rotate relative to the second fixing plate 5332. In this embodiment, the first eccentric wheel 531 is a driving wheel, and the first eccentric wheel 531 and the second eccentric wheel 532 are also hingedly connected. Therefore, the rotation of the first eccentric wheel 531 can drive the rotation of the second eccentric wheel 532.

[0101] Please continue to refer to Figures 7 and 8. The first eccentric wheel 531 is close to the fourth side 524, and the second eccentric wheel 532 is close to the second side 522. The first partition plate 400a is located on the fourth side 524, and the second partition plate 400b is located on the second side 522. It should be noted that the first partition plate 400a and the second partition plate 400b are for the convenience of distinguishing the first eccentric wheel 531 and the second eccentric wheel 532. The hard disk backplane 300 is provided below the first partition plate 400a and the second partition plate 400b along the height direction H, and the second connector 310 is provided on the side of the hard disk backplane 300 facing the second side 522 of the hard disk body 520. The hard disk modules 500 aligned along the first direction X form a row of electronic equipment modules, and the hard disk modules 500 aligned along the second direction Y form a column of service modules. The same partition 400 can be the first partition 400a of a column of hard disk modules 500, and can also be the second partition 400b of another column of hard disk modules.

[0102] In FIG7 , when the hard disk module 500 needs to be installed in the electronic device housing 100, the hard disk module 500 is first inserted into the accommodating space 150, with the third side 523 of the hard disk module 500 abutting against the bottom wall 130 of the electronic device housing 100. The first eccentric wheel 531 rotates, causing the first eccentric wheel 531 to partially extend out of the fourth side 524 of the hard disk body 520 to abut against the first partition 400a. The first partition 400a applies a thrust toward one side of the second partition 400b on the hard disk module 500 through the first eccentric wheel 531, causing the hard disk module 500 to move toward the second partition 400b as a whole. The first connector 510 on the second side 522 is plugged into the second connector 310 on the hard disk backplane 300 below the second partition 400b. Since the portion of the first eccentric wheel 531 extending out of the fourth side 524 continuously contacts the first partition 400 a , the first connector 510 and the second connector 310 are reliably plugged in, thereby installing the hard disk module 500 in the electronic device housing 100 .

[0103] In this embodiment, the installation process of the hard disk module 500 only requires the length of the first connector 510 and the second connector 310, and the hard disk module 500 can be installed in a relatively small space. A larger number of hard disk modules 200 can be installed in the electronic device 1000, thereby improving the storage density of the electronic device 1000. In addition, the hard disk module 500 can be securely installed in the electronic device housing 100 by abutting the first eccentric wheel 531 with the first partition 400a, making the installation method of the hard disk module 500 simple.

[0104] When the hard disk module 500 needs to be removed from the electronic device housing 100, the first eccentric wheel 531 is rotated and the first eccentric wheel 531 is retracted from the fourth side 524. Since the second eccentric wheel 532 is hinged to the first eccentric wheel 531, the rotation of the first eccentric wheel 531 can drive the second eccentric wheel 532 to rotate, so that the second eccentric wheel 532 partially extends out of the second side 522 to abut against the second partition 400b. The second partition 400b applies a thrust on the side of the hard disk module 500 toward the first partition 400a through the second eccentric wheel 532, so that the hard disk module 500 moves as a whole toward the first partition 400a, and the first connector 510 on the second side 522 is disconnected from the second connector 310 on the hard disk backplane 300 below the second partition 400b. Then the hard disk module 500 can be taken out of the electronic device housing 100.

[0105] When disassembling the hard disk module 500, the second eccentric wheel 532 can be brought into contact with the second partition plate 400b simply by linking the first eccentric wheel 531 and the second eccentric wheel 532. The first connector 510 and the second connector 310 can be disconnected under the interaction force between the second eccentric wheel 532 and the second partition plate 400b. No other tools are required during the disassembly process, making the disassembly process of the hard disk module 500 simple.

[0106] The hard disk module 500 provided in the embodiment of the present application is provided with a first connector 510, a hard disk body 520 and a hard disk mounting assembly 530, and the hard disk mounting assembly 530 includes a first eccentric wheel 531, a second eccentric wheel 532 and a fixing seat 533; the fixing seat 533 is connected to the hard disk body 520, and the first eccentric wheel 531 and the second eccentric wheel 532 are both hinged to the fixing seat 533, and the first eccentric wheel 531 and the second eccentric wheel 532 are hinged; when the hard disk module 500 needs to be installed, the first eccentric wheel 531 is used to abut against the first partition 400a of the electronic device 1000, and the first connector 510 is used to be plugged into the second connector 310 located on the side of the second partition 400b of the electronic device 1000; the installation process of the hard disk module 500 only needs to occupy the length of the first connector 510 and the second connector 310, and the installation of the hard disk module 500 can be completed in a smaller space, and a larger number of hard disk modules 200 can be installed in the electronic device 1000. Furthermore, the hard disk module 500 can be securely mounted in the electronic device housing 100 by abutting the first eccentric wheel 531 against the first partition plate 400a, simplifying installation of the hard disk module 500. To disassemble the hard disk module 500, the first eccentric wheel 531 is rotated, driving the second eccentric wheel 532 to rotate. The second eccentric wheel 532 abuts against the second partition plate 400b, exerting a thrust on the second partition plate 400b to move the hard disk module 500 in the first direction X toward the first partition plate 400a, thereby disconnecting the first connector 510 from the second connector 310. Only by linking the first eccentric wheel 531 and the second eccentric wheel 532, the second eccentric wheel 532 can be brought into contact with the second partition plate 400b, and the first connector 510 and the second connector 310 can be disconnected under the interaction force between the second eccentric wheel 532 and the second partition plate 400b. No other tools are required during the disassembly process, making the disassembly process of the hard disk module 500 simple.

[0107] Next, the specific hinge connection method of the first eccentric wheel 531 and the second eccentric wheel 532 and the fixing seat 533 is described.

[0108] FIG11 is an exploded schematic diagram of the hard disk mounting assembly in the hard disk module provided in an embodiment of the present application.

[0109] As shown in FIG11 , the fixing base 533 has a first rotating shaft 5333 and a second rotating shaft 5334. The projections of the first rotating shaft 5333 and the second rotating shaft 5334 on the first partition 400a are staggered. The first eccentric wheel 531 has a first eccentric hole 5311, into which the first rotating shaft 5333 is inserted. The second eccentric wheel 532 has a second eccentric hole 5321, into which the second rotating shaft 5334 is inserted. The hard disk mounting assembly 530 also includes a pull rod 534 connected to the first eccentric wheel 531 on one side of the first eccentric hole 5311. The pull rod 534 is used to apply torque to the first eccentric wheel 531 to rotate the first eccentric wheel 531, thereby driving the second eccentric wheel 532 to rotate.

[0110] Specifically, the pull rod 534 is connected to the driving wheel. In this embodiment, the first eccentric wheel 531 is the driving wheel, so the pull rod 534 is connected to the first eccentric wheel 531. The force applied to the pull rod 534 can be converted into a torque for rotating the first eccentric wheel 531 through the pull rod 534, so that the first eccentric wheel 531 rotates relative to the fixed seat 533.

[0111] The first rotating shaft 5333 is the rotation center of the first eccentric 531, and the second rotating shaft 5334 is the rotation center of the second eccentric 532. When the first eccentric 531 rotates, the second eccentric 532 rotates. Therefore, the projections of the first rotating shaft and the second rotating shaft 5334 on the first partition 400a (or the second partition 400b) along the first direction X cannot overlap, so that the torque generated by the rotation of the first eccentric 531 can be transmitted to the second eccentric 532, thereby driving the rotation of the second eccentric 532. The lever effect is formed by the pull rod 534, and a small force applied to the pull rod 534 can drive the first eccentric 531 and the second eccentric 532 to rotate, making the operation more labor-saving for the operator.

[0112] In this embodiment, in order to avoid interference between the pull rod 534 and the hard disk body 520, the rotation space of the pull rod 534 needs to be located above the hard disk body 520. Therefore, the distance between the first rotating shaft 5333 and the hard disk body 520 is greater than the distance between the second rotating shaft 5334 and the hard disk body 520. The pull rod 534 is connected to the first eccentric wheel 531 on one side of the first eccentric hole 5311, so that when installing and disassembling the hard disk module 500, the rotation space of the pull rod 534 is always located above the hard disk body 520.

[0113] Next, the manner in which the first eccentric wheel 531 and the second eccentric wheel 532 are hingedly connected via the connecting rod 535 will be described.

[0114] Please continue to refer to Figure 11. The first eccentric wheel 531 has a first hinge hole 5312, and the first hinge hole 5312 and the first eccentric hole 5311 are arranged opposite to each other along the diameter direction of the first eccentric wheel 531; the second eccentric wheel 532 has a second hinge hole 5322, and the second hinge hole 5322 and the second eccentric hole 5321 are arranged opposite to each other along the diameter direction of the second eccentric wheel 532; the connecting rod 535 has a third rotating shaft 5351 and a fourth rotating shaft 5352, and the third rotating shaft 5351 is inserted in the first hinge hole 5312, and the fourth rotating shaft 5352 is inserted in the second hinge hole 5322.

[0115] Specifically, in this embodiment, the connecting rod 535 extends along the first direction X, and the connecting rod 535 has a third rotating shaft 5351 and a fourth rotating shaft 5352 at both ends along the first direction X. The third rotating shaft 5351 is inserted into the first hinge hole 5312, and the fourth rotating shaft 5352 is inserted into the second hinge hole 5322. The first eccentric wheel 531 and the second eccentric wheel 532 can be hinged through the connecting rod 535, so that the connection method of the first eccentric wheel 531 and the second eccentric wheel 532 is simple.

[0116] The larger the distance between the first hinge hole 5312 and the first eccentric hole 5311, the greater the torque that can be transmitted by the connecting rod 535. However, if the diameter of the first eccentric 531 is set to be larger, it will occupy more space. Therefore, the diameter of the first eccentric 531 is generally close to the dimension of the second fixing plate 5332 along the height direction H. In this embodiment, the first hinge hole 5312 and the first eccentric hole 5311 are arranged relative to each other along the diameter direction of the first eccentric 531. Therefore, when the diameter of the first eccentric 531 is fixed, the distance between the first hinge hole 5312 and the first eccentric hole 5311 is larger, thereby allowing the connecting rod 535 to transmit greater torque.

[0117] The second hinge hole 5322 and the second eccentric hole 5321 are arranged on the second eccentric wheel 532 in the same manner as the first hinge hole 5312 and the first eccentric hole 5311 are arranged on the first eccentric wheel 531 , and are not described in detail here.

[0118] 9 to 11 , in this embodiment, the first eccentric wheel 531 and the second eccentric wheel 532 are both cams, the first eccentric hole 5311 and the first hinge hole 5312 are provided at both ends of the long axis of the first eccentric wheel 531, and the second eccentric hole 5321 and the second hinge hole 5322 are provided at both ends of the long axis of the second eccentric wheel 532. This arrangement can further increase the torque transmitted by the pull rod 534.

[0119] Next, the process of installing the hard disk module 500 in the electronic device housing 100 is described.

[0120] FIG12 is a first schematic diagram of the installation process of the hard disk module.

[0121] As shown in Figure 12, a pulling force F1 is applied to the pull rod 534 to rotate the first eccentric wheel 531 in the counterclockwise direction C2, ensuring that the first eccentric wheel 531 does not extend out of the fourth side 524 of the hard disk body 520. At this time, the second eccentric wheel 532 partially extends out of the second side 522 of the hard disk body 520, and then the hard disk module 500 is inserted into the accommodating space 150 near the first partition 400a.

[0122] FIG13 is a second schematic diagram of the installation process of the hard disk module.

[0123] As shown in Figure 13, a thrust F2 is applied to the pull rod 534, and the pull rod 534 drives the first eccentric wheel 531 to rotate around the first rotating shaft 5333 in the clockwise direction C1. As the first eccentric wheel 531 rotates, part of the first eccentric wheel 531 extends out of the fourth side 524 of the hard disk body 520. The part of the first eccentric wheel 531 extending out of the fourth side 524 applies pressure on the first partition 400a, and the first partition 400a applies a reaction force on the first eccentric wheel 531, so that the hard disk module 500 moves along the first direction X toward the second partition 400b. During the process of the hard disk module 500 moving along the first direction X toward the second partition 400b, the first connector 510 is plugged into the second connector 310.

[0124] Since the first rotating shaft 5333 and the second rotating shaft 5334 are staggered, the first eccentric wheel 531 drives the second eccentric wheel 532 to rotate in the counterclockwise direction C2 around the second rotating shaft 5334 through the connecting rod 535. When the first eccentric wheel 531 drives the second eccentric wheel 532 to rotate, the part of the second eccentric wheel 532 extending out of the second side 522 of the hard disk body 520 is gradually retracted. Therefore, the second eccentric wheel 532 can be prevented from interfering with the plug-in process of the first connector 510 and the second connector 310. After the installation is completed, the hard disk module 500 is in the state shown in Figure 7 in the accommodating space.

[0125] Next, the process of installing and removing the hard disk module 500 from the electronic device housing 100 is described.

[0126] FIG14 is a first schematic diagram of the disassembly process of the hard disk module; FIG15 is a second schematic diagram of the disassembly process of the hard disk module.

[0127] As shown in Figures 14 and 15, when the hard disk module 500 needs to be disassembled, a pulling force F1 is applied to the pull rod 534, and the pull rod 534 drives the first eccentric wheel 531 to rotate around the first rotating shaft 5333 in the counterclockwise direction C2. Since the first rotating shaft 5333 and the second rotating shaft 5334 are staggered, the first eccentric wheel 531 drives the second eccentric wheel 532 to rotate in the clockwise direction C1 through the connecting rod 535. As the second eccentric wheel 532 rotates, part of the second eccentric wheel 532 extends out of the second side 522 of the hard disk body 520. The part of the second eccentric wheel 532 extending out of the second side 522 applies pressure on the second partition 400b, and the second partition 400b applies a reaction force on the second eccentric wheel 532, thereby driving the hard disk module 500 to move along the first direction X toward the first partition 400a, thereby disconnecting the first connector 510 from the second connector 310.

[0128] During the rotation of the first eccentric wheel 531, the portion of the first eccentric wheel 531 extending out of the fourth side 524 of the hard disk body 520 is gradually retracted, thereby preventing the first eccentric wheel 531 from abutting against the first partition 400a, thereby leaving sufficient space for the hard disk module 500 to move toward the first partition 400a.

[0129] Then, the hard disk module 500 is taken out from the accommodating space 150 to complete the disassembly of the hard disk module 500 .

[0130] Finally, the limiting structure and locking structure on the hard disk installation assembly 530 are described.

[0131] Figure 16 is a second schematic diagram of the structure of the hard disk mounting assembly in the hard disk module provided in an embodiment of the present application; Figure 17 is a schematic diagram of the structure of Figure 16 in another state; and Figure 18 is a second exploded schematic diagram of the hard disk mounting assembly in the hard disk module provided in an embodiment of the present application. In Figure 17 , connecting rod 535 is omitted to clearly illustrate the structure of fixing base 533.

[0132] As shown in Figures 16 to 18, a first stop block 5335 is also provided on the fixed seat 533. The first stop block 5335 is arranged between the first eccentric wheel 531 and the second eccentric wheel 532 and is arranged close to the first eccentric wheel 531. When the pull rod 534 drives the first eccentric wheel 531 to rotate in the counterclockwise direction C2, the first stop block 5335 is used to limit the first eccentric wheel 531.

[0133] Specifically, the first stopper 5335 is disposed on the second fixing plate 5332. When the pull rod 534 drives the first eccentric 531 to rotate counterclockwise C2 until the portion of the first eccentric extension 531 extending beyond the second side edge 522 is retracted, the interaction force between the second eccentric 532 and the second partition 400b has disconnected the first connector 510 from the second connector 310. At this point, the ends of the first eccentric 531 and the second eccentric 532 that are opposite to each other abut against the first stopper 5335 (as shown in FIG16 ). The first stopper 5335 prevents the first eccentric 5335 from rotating further, thereby prompting the operator to remove the hard disk module 500 from the accommodating space 150 or to place the hard disk module 500 into the accommodating space 150, thereby avoiding the operator's manual judgment and improving the efficiency of installing and removing the hard disk module 500.

[0134] Please continue to refer to Figures 16 to 18. A second stopper 5336 is also provided on the fixed seat 533. The second stopper 5336 is provided between the first eccentric wheel 531 and the second eccentric wheel 532. When the pull rod 534 drives the first eccentric wheel 531 to rotate along the clockwise direction C1, the second stopper 5336 is used to limit the pull rod 534.

[0135] Specifically, the second stop block 5336 is also provided on the second fixed plate 5332, and the pull rod 534 drives the first eccentric wheel 531 to rotate in the counterclockwise direction C2 until the part of the first eccentric wheel extension 531 extending out of the second side edge 522 abuts against the first partition 400a, so that when the first connector 510 and the second connector 310 are plugged into place, the pull rod 534 abuts against the second stop block 5336 (as shown in FIG17 ), thereby preventing the pull rod 534 from exerting pressure on the connecting rod 535 due to further rotation.

[0136] Continuing to refer to FIG. 16 to FIG. 18 , a locking column 5337 is further provided on the fixing seat 533 , and a buckle 5341 is provided on the pull rod 534 . The buckle 5341 is used to engage with the locking column 5337 .

[0137] Specifically, a locking post 5337 is also provided on the second fixing plate 5332, and is staggered with the first stopper 5335 and the second stopper 5336. When the first connector 510 and the second connector 310 are plugged into place, the pull rod 534 extends along the first direction X. At this time, the buckle 5341 on the pull rod 534 engages with the locking post 5337 to secure the pull rod 534 (as shown in FIG17 ), thereby preventing the pull rod 534 from being accidentally triggered by external vibration.

[0138] By applying a pulling force to the end of the pull rod 534 away from the first eccentric wheel 531 , the buckle 5341 and the locking column 5337 can be released.

[0139] 7 , 8 , and 12 to 15 , the hard disk module 500 further includes a gasket 540 . The gasket 540 and the hard disk mounting assembly 530 are disposed on two opposite sides of the hard disk body 520 .

[0140] In this embodiment, the hard disk mounting assembly 530 is disposed on the first side 521 of the hard disk body 520, and the gasket 540 is disposed on the fourth side 524 of the hard disk body 520. The gasket 540 can prevent the fourth side 524 of the hard disk body 520 from directly contacting the bottom wall 130 of the electronic device housing 100. Thus, when the hard disk module 500 moves toward the first partition 400a or the second partition 400b in the electronic device housing 100, the hard disk body 520 can be prevented from being damaged by friction. In addition, when the hard disk module 500 is installed in the electronic device housing 100, the gasket 540 can also act as a shock absorber for the hard disk module 500, thereby further increasing the system reliability of the electronic device 1000. In this embodiment, the gasket 540 can be a rubber pad or a metal shrapnel.
