A hard drive removal control device and hard drive system

Abstract

The present invention discloses a hard disk disassembly control device and a hard disk system, and relates to the field of hard disk control technology. When the control module does not receive an identification signal indicating that a pop-up rod on a control bracket pops up, the control collar connection component is expanded, so that the first end of the pulling component will simultaneously pass through a first connecting rod and a second connecting rod in a mutually overlapping state, thereby driving the retractable component to be in a stretched state, preventing a drive module from moving, making it impossible for a user to operate, and preventing the pop-up rod from popping up; when the identification signal is received, the control collar connection component is compressed, so that the first connecting rod and the second connecting rod pass through the first end of the pulling component and separate from each other, and the retractable component in a stretched state will retract to drive the drive module to move, and the pop-up rod will automatically pop up, actively avoiding the loss of hard disk data due to user's misoperation, and ensuring accurate disassembly of the hard disk through the setting of software logic and hardware structure.

Description

Technical Field

[0001] The present invention relates to the technical field of hard disk control, and in particular to a hard disk disassembly control device and a hard disk system. Background Art

[0002] The hard disk can be fixed to the back plate by a bracket to prevent it from falling off or vibrating and affecting the use. Specifically, the bracket includes an iron bar and a force module for providing a user with a force point for pulling out. The force module specifically includes a removable rod and a button or a pull button. When the button is pressed or the pull button is pulled, the removable rod can automatically retract, so that the operator can pull the bracket out of the back plate to pull out the hard disk.

[0003] However, the backplane may include many hard disks at the same time, and it is very likely that the wrong hard disks will be pulled out, especially when the hard disk is small in size, such as a 2.5-inch hard disk, or when the backplane is nearly fully loaded. After the hard disks are installed on the backplane through corresponding brackets, the distance between them is usually close. At this time, even if the indicator light in the bracket where the hard disk to be pulled out is lit, there is still a possibility of human error, which may lead to data loss of the hard disk that is mistakenly operated, causing losses.

[0004] Therefore, how to find an effective way to avoid misoperation as much as possible and achieve accurate disassembly of the hard disk is a problem that needs to be solved urgently. Summary of the invention

[0053] The core of the present invention is to provide a hard disk disassembly control device and a hard disk system, which avoids the hard disk data loss caused by user's misoperation, and ensures the accurate disassembly of the hard disk through the setting of software logic and hardware structure.

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Please refer to Figure 1 and Figure 2 , Figure 1 A structural schematic diagram of a hard disk disassembly control device provided by the present invention, Figure 2 A schematic structural diagram of another hard disk disassembly control device provided by the present invention.

[0056] The hard disk disassembly control device is used to disassemble the hard disk arranged on the bracket 4 from the backplane, and comprises:

[0057] Control module 2;

[0058] A collar connection assembly 1, the first end of which is fixed to the back plate, and the second end of which is provided with a first connecting rod 11 and a second connecting rod 12 which overlap each other;

[0059] The pulling assembly 3 is arranged in the bracket 4, the first end of which is used to connect with the first connecting rod 11 and the second connecting rod 12 overlapped with each other, and the second end of which is connected with the driving module 42 in the bracket 4; the pulling assembly 3 includes a retractable member 31 connected with the driving module 42, and the retracting direction of the retractable member 31 is the same as the action direction of the driving module 42;

[0060] The control module 2 is used to control the clamp ring connection assembly 1 to expand when the identification signal indicating that the pop-up rod 43 on the control bracket 4 has not been received, so that the first end of the pulling assembly 3 simultaneously passes through the first connecting rod 11 and the second connecting rod 12 that overlap each other, thereby preventing the driving module 42 from moving and preventing the pop-up rod 43 from popping up; and control the clamp ring connection assembly 1 to compress when the identification signal is received, so that the first connecting rod 11 and the second connecting rod 12 pass through the first end of the pulling assembly 3 and separate from each other, so that the retractable part 31 in the stretched state retracts, thereby driving the driving module 42 to move and causing the pop-up rod 43 to pop up.

[0061] In this embodiment, considering that the prior art may include multiple hard disks on the backplane at the same time, it is very likely that the wrong hard disks will be pulled out, especially when the hard disks are small in size or the backplane is close to full load, and the distance between them is close, the button or pull button on the bracket 4 is likely to be misoperated, resulting in the hard disk being mistakenly pulled out, causing data loss. In order to solve the above technical problems, the present application provides a hard disk disassembly control device, which can control the ejectable rod 43 on the bracket 4 where the hard disk to be pulled out is located to automatically pop open through the coordinated setting of software and hardware, effectively avoiding the occurrence of the above misoperation.

[0062] First of all, it should be noted that the driving module 42 includes a pull button or a button. Combining the design of the pull button and the button on the bracket 4 in the prior art, it can be known that the pop-up rod 43 will only pop up when the pull button and the button are in place (that is, the movement distance reaches the preset distance). On this basis, when the hard disk and the corresponding pulling component 3 are installed on the backplane for the first time, the identification signal can be sent to the control module 2 first, then the collar connection component 1 is compressed, the first connecting rod 11 and the second connecting rod 12 of the collar connection component 1 will be separated from each other, the hard disk is correspondingly plugged into the hard disk plug-in component on the backplane, and the pulling component 3 is operated to make the driving module 42 move until the removable rod 43 remains in an un-removed state (corresponding to the driving module 42 being a button, the pulling component 3 is pulled outward toward the end away from the bracket 4; corresponding to the driving module 42 being a pull button, the pulling component 3 is pushed inward toward the first end facing the bracket 4), thereby completing the first step of the installation process; subsequently, an identification signal indicating that the removable rod 43 is prohibited from popping out is sent to the control module 2, the collar connection component 1 is expanded, the first connecting rod 11 and the second connecting rod 12 will engage with each other During the overlapping process, the first end of the pulling component 3 passes through the first connecting rod 11 and the second connecting rod 12 at the same time. It should be noted that the first end of the pulling component 3 can be understood as a loop structure similar to a pull ring. The area of ​​the hollow circle of the pull ring is large enough to ensure that the first connecting rod 11 and the second connecting rod 12 can just move therein to achieve the above-mentioned overlapping and separation. At the same time, when the first connecting rod 11 and the second connecting rod 12 are in the overlapping state, it is assumed that the structure composed of the overlapped first connecting rod 11 and the second connecting rod 12 is the first structure. The operating distance between the first structure and the edge of the pull ring is not enough to make the driving module 42 move sufficiently (that is, the movement distance reaches the preset distance) to realize the pop-up rod 43 to pop open, so as to ensure that the user's operation of the driving module 42 cannot cause the pop-up rod 43 to pop open, thereby avoiding misoperation, and the installation is completed.

[0063] Therefore, when the control module 2 does not receive the identification signal (the identification signal can be sent to the control module 2 by the user), the control collar connection assembly 1 always remains open after the above-mentioned installation. At this time, the first connecting rod 11 and the second connecting rod 12 always remain overlapped with each other, and the first end of the pulling assembly 3 passes through the overlapped first connecting rod 11 and the second connecting rod 12 at the same time. Combined with the design of the first end of the pulling assembly 3 described above, no matter how the user operates the drive module 42, the drive module 42 cannot be moved into place, and the pop-up rod 43 cannot be popped open, and naturally the hard disk cannot be disassembled, and the hard disk will naturally not be pulled out due to misoperation.

[0064] When the user wants to unplug the hard disk, he only needs to send an identification signal to the control module 2 indicating that the pop-up rod 43 on the bracket 4 corresponding to the hard disk is popped out. The control module 2 will then control the compression of the clamping ring connecting assembly 1, driving the first connecting rod 11 and the second connecting rod 12 to pass through the first end of the pulling assembly 3 and separate from each other. The retractable part 31 that was originally in a stretched state will retract, and will move a certain distance during the retraction process, thereby driving the drive module 42 to move, so that the drive module 42 moves into place, and then the pop-up rod 43 automatically pops out. At this time, the user only needs to unplug the hard disk whose pop-up rod 43 has been popped out, and there will be no situation where other hard disks whose pop-up rods 43 have not been popped out need to be disassembled.

[0065] It should be noted that the control module 2 includes but is not limited to a BMC (Baseboard Management Controller) and related peripheral circuits, which are not particularly limited here and depend on the actual situation as long as the execution logic of the control module 2 in this application can be implemented.

[0066] For details, please refer to Figure 1 , where, due to the limited space of the picture 1, the control module 2 is shown here in the form of a circle plus a reference mark. It should also be noted that, Figure 1 The driving module 42 is taken as a button as an example for illustration (and considering the emphasis of the overall structure of this embodiment, Figure 1 The relationship between the button of the force module 44 and the retractable rod 43 provided on the bracket 4 is only briefly shown. Figure 2 , where, due to the limited space of Figure 2, the control module 2 is also shown here in the form of a circle plus a reference mark. It should also be noted that, Figure 2 The driving module 42 is taken as a button as an example for illustration (and considering the emphasis of the overall structure of this embodiment, Figure 2 In addition, in combination with actual application, the hard disk needs to be plugged into the back panel. Therefore, more specifically, the second structure composed of the hard disk and the bracket 4 is actually separated from the collar connection component 1, that is, the two are arranged on both sides of the back panel (such as Figure 1 and Figure 2 As shown), a hole large enough is provided on the back plate so that the first end of the pulling component 3 can pass through the hole to implement its execution logic.

[0067] In addition, if Figure 1 As shown, when the driving module 42 is a button, the action direction of the button is up and down (ie, moving toward the direction close to the hard disk or away from the hard disk), and the action direction of the retractable member 31 is the same; Figure 2As shown, when the driving module 42 is a pull button, the movement direction of the pull button is left-right direction (perpendicular to the above-mentioned up-down direction), and the movement direction of the retractable member 31 is the same.

[0068] In summary, the present application provides a hard disk disassembly control device. When the control module 2 does not receive the identification signal indicating that the pop-up rod 43 on the control bracket 4 has popped out, the control collar connection assembly 1 is expanded, so that the first end of the pulling assembly 3 will simultaneously pass through the first connecting rod 11 and the second connecting rod 12 that are in a state of overlapping each other, thereby driving the retractable member 31 to be in a stretched state, preventing the drive module 42 from moving, and the user cannot operate it, thereby preventing the pop-up rod 43 from popping out; when the identification signal is received, the control collar connection assembly 1 is compressed, so that the first connecting rod 11 and the second connecting rod 12 pass through the first end of the pulling assembly 3 and separate from each other, and the retractable member 31 in the stretched state will retract to drive the drive module 42 to move, and the pop-up rod 43 will automatically pop out, actively avoiding the loss of hard disk data due to user's misoperation, and ensuring accurate disassembly of the hard disk through the setting of software logic and hardware structure.

[0069] Based on the above embodiments:

[0070] As a preferred embodiment, when the driving module 42 is a button;

[0071] The pulling component 3 specifically includes:

[0072] The retractable member 31 has a first end fixed to the support frame in the bracket 4 and close to the hard disk side, and a second end connected to the button;

[0073] A first pull ring 32, used to connect with the first connecting rod 11 and the second connecting rod 12 which overlap each other;

[0074] One end of the first pull tab 33 is connected to the button, and the other end is connected to the first pull ring 32 .

[0075] In this embodiment, when the driving module 42 is a button, the pulling assembly 3 specifically includes a retractable member 31, a first pull ring 32 and a first pull tab 33. The specific connection structure is as described above and will not be repeated here. Therefore, the first pull ring 32 is the structure of the first end of the pulling assembly 3. For details, please refer to Figure 1 First of all, it should be noted that Figure 1As a structural illustration only, the first connecting rod 11 and the second connecting rod 12 are in an overlapping state, and the first pull ring 32 passes through the overlapping first connecting rod 11 and the second connecting rod 12 at the same time. As an example, the design is only illustrated here. Therefore, the size of the first pull ring 32 needs to be set according to actual needs, that is, it satisfies the above-mentioned: the area of ​​the hollow circle of the first pull ring 32 is large enough to ensure that the first connecting rod 11 and the second connecting rod 12 can just move therein to achieve overlapping and separation. At the same time, when the first connecting rod 11 and the second connecting rod 12 are in an overlapping state, assuming that the structure composed of the overlapping first connecting rod 11 and the second connecting rod 12 is the first structure, the operating distance between the first structure and the edge of the first pull ring 32 is not enough to make the button move enough to achieve the pop-up rod 43 to pop open, so as to ensure that the user's operation of the button cannot cause the pop-up rod 43 to pop open, thereby avoiding misoperation.

[0076] It should also be noted that, it can be seen that at this time, the integrated pull ring and pull tab structure composed of the first pull ring 32 and the first pull tab 33 is located on the same side of the bracket 4 as the button. Figure 1 As shown, both are on the left.

[0077] In addition, the bracket 4 includes an iron bar 41 fixed to the hard disk, and the first pull tab 33 can be disposed in a partial space between the hard disk and the iron bar 41 .

[0078] As a preferred embodiment, the retractable member 31 is a first spring.

[0079] In this embodiment, since the spring has good telescopic performance, the telescopic member 31 can be a first spring. Therefore, when the control module 2 does not receive the identification signal, the first spring is always in a stretched state ( Figure 1 The first spring is shown in the stretched state), but due to the action of the first pull-tab 33 against the driving module 42, the pop-up rod 43 cannot pop out; when the control module 2 receives the identification signal, the first spring retracts from the stretched state, driving the driving module 42 to move into place (and the movement distance reaches the preset distance), so as to realize the automatic pop-up of the pop-up rod 43.

[0080] As a preferred embodiment, the retractable member 31 includes:

[0081] A first magnetic attraction module 312, a first end of which is fixed on the button and a control end of which is connected to the control module 2;

[0082] A second magnetic attraction module 311, a first end of which is fixed to the support frame, and a control end of which is connected to the control module 2;

[0083] The specific process of retracting the retractable member 31 in the stretched state includes:

[0084] When an identification signal is received, the second ends of the first magnetic module 312 and the second magnetic module 311 are controlled to be magnetically connected to drive the button to move and make the pop-up rod 43 pop open; when no identification signal is received, the second ends of the first magnetic module 312 and the second magnetic module 311 are controlled to repel each other to prevent the button from moving.

[0085] In the present embodiment, the inventors consider that in order to further reliably ensure that the driving module 42 does not move into place at all times, that is, its movement distance does not reach the preset distance, the retractable part 31 can be composed of a first magnetic module 312 and a second magnetic module 311. Therefore, when the control module 2 does not receive the identification signal, it can control the first magnetic module 312 and the second end of the second magnetic module 311 to repel each other (essentially, it can be understood as the mutual repulsion between the N pole and the N pole of a magnet, or the S pole and the S pole). The repulsive force can ensure that the button does not move into place at all times, and thus the pop-up rod 43 cannot pop out; when the control module 2 receives the identification signal, it controls the first magnetic module 312 and the second end of the second magnetic module 311 to be magnetically connected (essentially, it can be understood as the mutual attraction between the N pole and the S pole of a magnet), thereby driving the button to move into place, so that the pop-up rod 43 automatically pops out.

[0086] For details, please refer to Figure 3 As shown, it should be noted that only the connection method between the first magnetic module 312 and the second magnetic module 311 and the control module 2 is structurally illustrated here, and the specific structure of the first magnetic module 312 and the second magnetic module 311 is not particularly limited here. It can be set according to actual needs and can realize the above-mentioned execution logic.

[0087] As a preferred embodiment, the retractable member 31 further includes:

[0088] The second spring has one end connected to the second end of the first magnetic attraction module 312 , and the other end connected to the second end of the second magnetic attraction module 311 .

[0089] In this embodiment, the retractable part 31 may also include a second spring, which can essentially play a supporting role. Due to the existence of the second spring, the control module 2 can control the second ends of the first magnetic module 312 and the second magnetic module 311 to repel each other when the identification signal is not received, and the second spring is in a stretched state at this time; subsequently, when the identification signal is received, when the retraction force of the second spring is large enough to ensure that the driving module 42 is in place, it is only necessary to control the first magnetic module 312 and the second magnetic module 311 to lose the magnetic force, so that the second spring in the stretched state will retract, driving the driving module 42 to move and the movement distance reaches the preset distance, so that the pop-up rod 43 pops open; of course, the control module 2 can also follow the above logic to control the second ends of the first magnetic module 312 and the second magnetic module 311 to attract each other, so that the second spring is compressed, but the pop-up logic of the pop-up rod 43 should be guaranteed.

[0090] As a preferred embodiment, when the driving module 42 is a pull button;

[0091] The pulling component 3 specifically includes:

[0092] A second pull ring 34;

[0093] A third connecting rod 36 is plugged into the pull button;

[0094] A second pull tab 35 in a bent shape, one end of which is connected to the first surface of the third connecting rod 36, and the other end of which is connected to the second pull ring 34;

[0095] The retractable member 31 has a first end connected to the second surface of the third connecting rod 36, the second surface being away from the first surface; and a second end fixed to a first side of the hard disk bracket 4, the first side being the side where the pull button is located and being parallel to the second surface.

[0096] In this embodiment, when the driving module 42 is a pull button, the pulling assembly 3 specifically includes a second pull ring 34, a third connecting rod 36, a second pull tab 35 and a retractable member 31. Therefore, the specific connection structure is as described above and will not be repeated here. It can be seen that the second pull ring 34 is the structure of the first end of the pulling assembly 3. For details, please refer to Figure 2 It should be noted that Figure 2As a structural illustration only, the first connecting rod 11 and the second connecting rod 12 are in an overlapping state, and the second pull ring 34 passes through the overlapping first connecting rod 11 and the second connecting rod 12 at the same time. The structural block diagram here is only for illustration. Therefore, the size of the second pull ring 34 needs to be set according to actual needs, that is, it meets the above-mentioned: the area of ​​the hollow circle of the second pull ring 34 is large enough to ensure that the first connecting rod 11 and the second connecting rod 12 can just move therein to achieve overlapping and separation. At the same time, when the first connecting rod 11 and the second connecting rod 12 are in an overlapping state, assuming that the structure composed of the overlapping first connecting rod 11 and the second connecting rod 12 is the first structure, the operating distance between the first structure and the edge of the second pull ring 34 is not enough to make the action of the pull button sufficient to achieve the pop-up rod 43 to pop open, so as to ensure that the user's operation of the pull button cannot cause the pop-up rod 43 to pop open, thereby avoiding misoperation.

[0097] It should also be noted that the second pull ring 34 and the pull button are located on both sides of the bracket 4, that is, Figure 2 As shown, the second pull ring 34 is located on the right side, the pull button is located on the left side, and the second pull tab 35 can be bent. The specific position of the first side can be seen in Figure 2 shown.

[0098] It should be noted that the scalable components here include but are not limited to: Figure 2 Therefore, when the control module 2 does not receive the identification signal, the fourth spring is always in a stretched state ( Figure 2 The fourth spring is shown in the stretched state), but because the second pull-tab 35 pulls the third connecting rod 36, that is, pulls the driving module 42 to prevent the movement distance of the driving module 42 from reaching the preset distance, the pop-up rod 43 cannot pop out; when the control module 2 receives the identification signal, the fourth spring retracts from the stretched state, driving the driving module 42 to move into place, so as to realize the automatic pop-up of the pop-up rod 43.

[0099] As a preferred embodiment, the retractable member 31 includes:

[0100] A third magnetic attraction module 314, the control end of which is connected to the control module 2, and the first end of which is fixed to the second surface of the third connecting rod 36;

[0101] A fourth magnetic attraction module 313, the control end of which is connected to the control module 2, and the first end of which is fixed on the first side of the hard disk bracket 4;

[0102] The specific process of retracting the retractable member 31 in the stretched state includes:

[0103] When an identification signal is received, the second ends of the third magnetic module 314 and the fourth magnetic module 313 are controlled to be magnetically connected to drive the pull button to move and make the removable rod 43 pop open; when no identification signal is received, the second ends of the third magnetic module 314 and the fourth magnetic module 313 are controlled to repel each other to prevent the pull button from moving.

[0104] In the present embodiment, the inventors consider that in order to further reliably ensure that the driving module 42 does not move into place at all times, that is, its movement distance does not reach the preset distance, the retractable member 31 can be composed of a third magnetic module 314 and a fourth magnetic module 313. Therefore, when the control module 2 does not receive the identification signal, it can control the third magnetic module 314 and the second end of the fourth magnetic module 313 to repel each other (essentially, it can be understood as the mutual repulsion between the N pole and the N pole of a magnet, or the S pole and the S pole). The repulsive force can ensure that the pull button does not move into place at all times and does not reach the preset distance, so that the pop-up rod 43 cannot pop out; when the control module 2 receives the identification signal, it controls the third magnetic module 314 and the second end of the fourth magnetic module 313 to be magnetically connected (essentially, it can be understood as the mutual attraction between the N pole and the S pole of a magnet), thereby driving the pull button to move into place, so that the pop-up rod 43 automatically pops out.

[0105] For details, please refer to Figure 4 As shown, it should be noted that only the connection structure of the third magnetic module 314 and the fourth magnetic module 313 and the control module 2 is illustrated here, and the specific structure of the third magnetic module 314 and the fourth magnetic module 313 is not particularly limited here, and can be set according to actual needs and can realize the above execution logic. The specific position of the first side can be seen in Figure 4 shown.

[0106] As a preferred embodiment, the collar connection assembly 1 comprises:

[0107] Three hinged fourth connecting rods 13 are respectively fixed to the back plate and one end of the first connecting rod 11;

[0108] Three hinged fifth connecting rods 14 are respectively fixed to the back plate and one end of the second connecting rod 12;

[0109] The fifth magnetic attraction module 15 has a first end disposed on the fourth connecting rod 13 hinged in the middle and is also connected to the control module 2;

[0110] The sixth magnetic attraction module 16 has a first end disposed on the fifth connecting rod 14 hinged in the middle and is also connected to the control module 2;

[0111] The control collar connection assembly 1 is expanded, comprising:

[0112] Control the second ends of the fifth magnetic module 15 and the sixth magnetic module 16 to repel each other, so that the fourth connecting rods 13 and the fifth connecting rods 14 are spread apart;

[0113] The control collar connection assembly 1 is compressed, comprising:

[0114] The second ends of the fifth magnetic module 15 and the sixth magnetic module 16 are controlled to be magnetically connected, so that each of the fourth connecting rods 13 and each of the fifth connecting rods 14 are compressed.

[0115] In this embodiment, the collar connection assembly 1 specifically includes: three hinged fourth connecting rods 13, three hinged fifth connecting rods 14, a fifth magnetic attraction module 15 and a sixth magnetic attraction module 16. For details, please refer to Figures 1 to 4 As shown in any of the accompanying drawings, Figures 1 to 4 In the description, the collar connection assembly 1 is in the expanded state as an example. It can be understood that the three hinged fourth connecting rods 13 and the three hinged fifth connecting rods 14 can form a hexagonal structure when expanded, and assuming that the fourth connecting rod 13 connected to one end of the first connecting rod 11 is the first reference rod, the connection between the first reference rod and the first connecting rod 11 should be a fixed connection, that is, the angle formed by the two is fixed, and each fourth connecting rod 13 itself is hinged and can rotate; similarly, assuming that the fifth connecting rod 14 connected to one end of the second connecting rod 12 is the second reference rod, the connection between the second reference rod and the second connecting rod 12 should also be a fixed connection, that is, the angle formed by the two is fixed, and each fifth connecting rod 14 itself is hinged and can rotate. On the above basis, the expansion of the collar connection assembly 1 and the compression of the collar connection assembly 1 can be achieved.

[0116] It should also be noted that the compression can be understood essentially as: each fourth connecting rod 13 and each fifth connecting rod 14 are connected by Figure 1 The hexagonal structure shown is transformed into a parallel, rectangular structure so as to enable the first connecting rod 11 and the second connecting rod 12 to pass through the first end of the traction assembly.

[0117] As a preferred embodiment, the collar connection assembly 1 further includes:

[0118] The third spring has one end connected to the second end of the fifth magnetic attraction module 15 , and the other end connected to the second end of the sixth magnetic attraction module 16 .

[0119] In this embodiment, the clamping ring connection assembly 1 may further include a third spring. The connection method is as described above and will not be repeated here. It should be noted that the third spring is essentially a supporting spring and does not affect the above-mentioned control logic of the retractable assembly.

[0120] The present invention also provides a hard disk system, including a back plate and a bracket, and also includes the hard disk disassembly control device as described above.
