Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to an unlocking control device. This application also relates to a server having the unlocking control device. Background Technology

[0002] In recent years, server shipments have increased year by year, and market competition has become increasingly fierce. Therefore, improving the overall advantages of servers in every detail is crucial to winning in the market. As we all know, information, as an asset, is an indispensable resource for enterprises or organizations to conduct business operations and management, and it is also the main carrier of corporate property and personal privacy. In particular, customers have increasingly strong demands for server storage security. Therefore, ensuring server information security is an important aspect of improving the overall quality of servers. Currently, improving server usage security has become a requirement for server suppliers to enhance their product differentiation competitiveness.

[0003] In existing technologies, such as Figure 1 As shown, the server storage hard drive is mainly an external hard drive module 1. The conventional disassembly method involves manually pressing a specific position to unlock and pull out the hard drive module 1, thus removing it from the chassis 2. However, this design lacks physical anti-theft functionality. When the hard drive module 1 is directly exposed on the surface of the chassis 2, it is extremely easy for criminals to disassemble it and steal the stored data, posing a certain security risk. Therefore, in order to meet the application needs of customers in protecting information security, it is necessary for those skilled in the art to provide a convenient and highly secure unlocking control device. Summary of the Invention

[0004] The purpose of this application is to provide an unlocking control device capable of locking the hard drive module in the chassis and unlocking and removing the hard drive module from the chassis, which is convenient to operate and improves security and ease of unlocking. Another purpose of this application is to provide a server including the above-mentioned unlocking control device.

[0005] To achieve the above objectives, this application provides an unlocking control device for controlling the first connector to unlock and be removed from the second connector, comprising:

[0006] A connecting component, the connecting component including a push rod and a movable part, the movable part being movable in a first direction to drive the push rod to move in the first direction, so that the first connecting part and the second connecting part switch from a locked state to an unlocked state;

[0007] A rotation control module, comprising a lock head limiting rod, the lock head limiting rod being rotatable about an axis in a second direction to restrict the movement of the movable part or to release the restriction on the movement of the movable part;

[0008] A control board, connected to the rotation control module, is used to send control signals to the rotation control module to control the rotation of the lock head limit rod;

[0009] An unlock command receiving module, connected to the control board, is used to transmit a specific unlock command received to the control board.

[0010] In some embodiments, an infrared transmitting module is further included, wherein the unlock command receiving module is an infrared receiving module, and the infrared transmitting module can transmit infrared signals of a specific wavelength and intensity to the infrared receiving module so that the infrared receiving module transmits the received infrared signals to the control board.

[0011] In some embodiments, the infrared receiving module includes an infrared receiving panel, an infrared reflector, an infrared light guide column, and an infrared photosensitive device. The infrared receiving panel receives the infrared signal, the infrared reflector reflects the infrared signal to the infrared light guide column, and the infrared light guide column transmits the infrared signal to the infrared photosensitive device.

[0012] In some embodiments, the unlock command receiving module is a fingerprint module.

[0013] In some embodiments, the rotation control module is an electromagnetic control module, which further includes a connector and an electronic lock. The electronic lock includes the lock head limiting rod, and the connector is disposed on the control board and connected to the electronic lock so that the lock head limiting rod rotates when energized.

[0014] In some embodiments, the connecting assembly further includes a door panel for fixing to the first connector, and the movable member is movably connected to the door panel.

[0015] In some embodiments, the door panel is provided with a slide groove, and the movable member can slide along the slide groove to drive the push rod to move in the first direction.

[0016] In some embodiments, the door panel is further provided with a receiving groove, the movable member includes a toggle part and a connecting part, the connecting part passes through the sliding groove, the toggle part is disposed in the receiving groove, and by toggle the toggle part, the connecting part slides along the sliding groove.

[0017] In some embodiments, the connecting assembly further includes a fixed base, which is fixedly connected to the push rod. The movable member is provided with a protruding claw, which abuts against the fixed base. By moving the movable member, the fixed base and the push rod can be driven to move along the first direction.

[0018] In some embodiments, the connection assembly further includes an elastic element for providing an elastic force to the push rod to cause the push rod to tend to extend out of the first connection element.

[0019] In some embodiments, the push rod is provided with a first limiting protrusion, and the two ends of the elastic member abut against the first limiting protrusion and the second limiting protrusion in the first connecting member, respectively.

[0020] In some embodiments, a pop-out component is further included, one end of which is connected to the control panel and the other end is used to abut against the first connector. The pop-out component can provide an elastic force to the first connector so that the first connector tends to extend out of the second connector along the second direction.

[0021] In some embodiments, an emergency slide is further included, the emergency slide being slidably connected to the first connector, and the push rod having an inclined surface, wherein by pushing the emergency slide, the emergency slide contacts the inclined surface, thereby causing the push rod to retract.

[0022] This application also provides a server, including a chassis and a hard disk module detachably connected to the chassis, and further including the unlocking control device described in any of the above claims, wherein the unlocking control device is disposed on the hard disk module, and the hard disk module and the chassis are unlocked through the unlocking control device.

[0023] In some embodiments, the chassis is provided with a slot, and when the push rod disengages from the slot, the hard drive module is unlocked from the chassis.

[0024] Compared to the aforementioned background technology, the unlocking control device provided in this application embodiment is used to control the first connecting member to be unlocked and removed from the second connecting member. The unlocking control device includes a connecting assembly, a rotation control module, a control board, and an unlocking command receiving module. The connecting assembly includes a push rod and a movable member. The movable member is movably connected to the first connecting member and can move along a first direction to drive the push rod to move along the first direction, thereby switching the first and second connecting members from a locked state to an unlocked state. The rotation control module includes a lock head limiting rod, which can rotate around an axis in a second direction to restrict the movement of the movable member or release the restriction on its movement. The control board is connected to the rotation control module and is used to send control signals to the rotation control module to control the rotation of the lock head limiting rod. The unlocking command receiving module is connected to the control board and is used to transmit a received specific unlocking command to the control board.

[0025] Understandably, in actual use, when the first connector needs to be detached from the second connector, the unlocking command receiving module receives the user's specific unlocking command. After receiving the specific unlocking command, the control board sends a control signal to the rotation control module to control the rotation of the lock head limit rod. At this time, the movement limit of the movable part is released, and it can move along the first direction. By turning or pushing the movable part, the push rod is driven to move along the first direction, so that the first connector and the second connector switch from the locked state to the unlocked state, and finally the first connector and the second connector are unlocked. At this time, the first connector can be taken out from the second connector along the second direction. Compared with the traditional unlocking device, the unlocking control device provided in this application embodiment first receives the user's specific unlocking command through the unlocking command receiving module, then controls the rotation of the lock head limit rod of the rotation control module through the control board, and finally, through mechanical transmission, that is, after the movable part drives the push rod to move along the first direction, the first connector and the second connector switch from the locked state to the unlocked state. This unlocking control device can be applied to external hard drive modules. It achieves semi-automatic unlocking operation through the linkage of the unlocking command receiving module, control board, rotation control module and connecting components, thereby preventing the hard drive module from being deliberately disassembled and achieving the purpose of anti-theft. It is not only easy to operate, but also improves the security of external hard drive modules. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0047] The unlocking control device 10 provided in this application embodiment is used to control the first connector to be unlocked from the second connector and removed. The unlocking control device 10 includes a connecting component 100, a rotation control module 200, a control board 300, and an unlocking command receiving module 400.

[0048] Of course, depending on the actual application needs, the unlocking control device 10 can be applied to a server to control the first connector (the first connector is the hard disk module 1) to be unlocked and removed from the second connector (the second connector is the chassis 2). The control board 300 can be a circuit board, which is located in the server chassis 2, and the hard disk module 1 is detachably connected to the circuit board.

[0049] The connecting component 100 includes a push rod 101 and a movable member 102. The movable member 102 is movably connected to the first connecting member. The movable member 102 can move along a first direction to drive the push rod 101 to move along the first direction, so that the first connecting member and the second connecting member switch from a locked state to an unlocked state.

[0050] It should be noted that when the push rod 101 retracts along the first direction, the push rod 101 disengages from the second connector, allowing the first connector to be unlocked and removed from the second connector; when the push rod 101 extends along the first direction, the first connector connects to the second connector through the connecting assembly 100, thereby locking the first connector and the second connector.

[0051] To facilitate limiting the movement of the movable part 102, the rotation control module 200 includes a lock head limiting rod 2021, which can rotate around an axis in a second direction to restrict the movement of the movable part 102 or release the restriction on the movement of the movable part 102. At the same time, the control board 300 is connected to the rotation control module 200 and is used to send control signals to the rotation control module 200 to control the rotation of the lock head limiting rod 2021. The unlocking command receiving module 400 is connected to the control board 300 and is used to transmit specific unlocking commands received to the control board 300.

[0052] It should be noted that the first and second directions can be determined based on the unlocking action. Preferably, the first direction is as follows: Figure 2 The X-axis direction is shown, and the second direction is as follows: Figure 2 The Y-axis direction is shown.

[0053] Understandably, in actual use, when it is necessary to detach the first connector from the second connector, the unlocking command receiving module 400 receives the user's specific unlocking command. After receiving the specific unlocking command, the control board 300 sends a control signal to the rotation control module 200 to control the lock head limit rod 2021 to rotate. At this time, the movement limit of the movable part 102 is released, and it can move along the first direction. By flicking or pushing the movable part 102, the push rod 101 is driven to move along the first direction, so that the first connector and the second connector switch from the locked state to the unlocked state, and finally the first connector and the second connector are unlocked. At this time, the first connector can be taken out from the second connector along the second direction.

[0054] In other words, the unlocking control device 10 provided in this application embodiment mainly includes two parts of action during the unlocking process. First, the limit on the movable part 102 is released through the linkage control of the unlocking command receiving module 400, the control board 300, and the rotation control module 200. Second, the movement of the movable part 102 after the limit is released is manually controlled, thereby realizing the unlocking operation.

[0055] Preferably, the rotation control module 200 can be an electromagnetic control module, such as an electronic lock control device. The electronic lock control device can rotate the lock head limit rod 2021 by 90° when powered on, thereby restricting or releasing the movement of the moving part 102. The unlocking command receiving module 400 can be a module that can issue a specific unlocking command, such as an infrared receiving module or a fingerprint module.

[0056] Compared to traditional unlocking devices, the unlocking control device 10 provided in this embodiment first receives a specific unlocking command from the user through the unlocking command receiving module 400, then controls the rotation control module 200's lock limit rod 2021 to rotate through the control board 300, and finally, through mechanical transmission, that is, the moving part 102 drives the push rod 101 to move along the first direction, so that the first connecting part and the second connecting part switch from the locked state to the unlocked state. This unlocking control device 10 can be applied to the external hard disk module 1. Through the linkage of the unlocking command receiving module 400, the control board 300, the rotation control module 200 and the connecting component 100, a semi-automatic unlocking operation is achieved, thereby preventing the hard disk module 1 from being deliberately disassembled and achieving the purpose of anti-theft. It is not only convenient to operate, but also improves the security of the external hard disk module 1.

[0057] When the rotation control module 200 adopts an electronic lock control device and the unlocking command receiving module 400 adopts an infrared receiving module, the unlocking control device 10 provided in this application embodiment can use a combination of optical control, electronic lock control and mechanical transmission control to realize semi-automatic operation of unlocking the hard disk module 1.

[0058] The following is a detailed explanation:

[0059] In some embodiments, the unlocking control device 10 further includes an infrared transmitting module, which can be an infrared remote controller used to transmit infrared signals. Correspondingly, the unlocking command receiving module 400 is an infrared receiving module.

[0060] In this way, the infrared transmitting module can transmit infrared signals of a specific wavelength and intensity to the infrared receiving module, so that the infrared receiving module can transmit the received infrared signals of a specific wavelength and intensity to the control board 300. After processing the infrared signal, the control board 300 can supply power to the electronic lock 202 control device, so that the electronic lock 202 control device rotates after being powered on, releasing the limit on the moving part 102.

[0061] Specifically, the infrared receiving module includes an infrared receiving panel 401, an infrared reflector 402, an infrared light guide column 403, and an infrared photosensitive device 404. The infrared receiving panel 401 receives infrared signals, the infrared reflector 402 reflects the infrared signals to the infrared light guide column 403, and the infrared light guide column 403 transmits the infrared signals to the infrared photosensitive device 404.

[0062] Understandably, during the unlocking operation, an infrared signal of a specific wavelength and intensity is first emitted via the infrared emitting module. The infrared receiving panel 401 receives this signal, and the infrared reflector 402 reflects it to the infrared light guide column 403. The light guide column 403 then transmits the signal to the infrared photosensitive device 404. Upon receiving the signal, the photosensitive device 404 sends it to the control board 300 for processing. After processing, the control board 300 powers the electronic lock 202 control device. Then, the lock head limit lever 2021 of the electronic lock control device rotates 90° after being energized, releasing the limit on the movable part 102. Finally, the movable part 102 is manually controlled to retract the push rod 101 along the first direction, thereby unlocking the first connector from the second connector. At this point, the first connector can be removed from the second connector along the second direction.

[0063] In actual use, when there is a need to disassemble the hard drive module 1, the infrared emitting module needs to be brought close to the infrared receiving panel 401 fixed on the hard drive bracket. When the infrared photosensitive device 404 fixed on the server receives an infrared signal of a specific wavelength and intensity, it will control the locking limit rod 2021 to rotate 90°. At this time, the movable part 102 can be pulled and the push rod 101 can be driven to move, and finally the hard drive module 1 and the chassis 2 can be unlocked.

[0064] In some embodiments, the unlock command receiving module 400 may also be a fingerprint module. The fingerprint module is used to receive specific fingerprint unlock signals, such as by recording the fingerprint information of a specific user in the fingerprint module. In this way, the unlocking operation can only be performed under the unlocking operation of the specific user, thereby preventing the hard disk module 1 from being deliberately disassembled and achieving the purpose of theft prevention.

[0065] In some embodiments, the rotation control module 200 is an electromagnetic control module, which further includes a connector 201 and an electronic lock 202. The electronic lock 202 includes the aforementioned lock head limiting rod 2021. The connector 201 is disposed on the control board 300 and connected to the electronic lock 202, so that the lock head limiting rod 2021 rotates when energized.

[0066] It should be noted that the electronic lock 202 will only cause the lock head limit rod 2021 to rotate when the power is on, thereby releasing the limit on the moving part 102; when the power is off, the lock head limit rod 2021 of the electronic lock 202 will automatically reset to the initial state, which is the state that restricts the movement of the moving part 102.

[0067] Of course, depending on the specific structural requirements, the rotation angle of the lock head limiting rod 2021 in the energized state can be adjusted. Preferably, the rotation angle of the lock head limiting rod 2021 in the energized state can be 90°. In this way, the lock head limiting rod 2021 does not rotate in the de-energized state, and the movable part 102 cannot be manually triggered to move; after the lock head limiting rod 2021 rotates 90° in the energized state, the limiting effect of the lock head limiting rod 2021 on the movable part 102 can be released, so that the movable part 102 can be manually triggered to move, thereby driving the push rod 101 to retract in the first direction.

[0068] In some embodiments, the connecting assembly 100 further includes a door panel 103, which is fixed to the first connector, and the movable member 102 is movably connected to the door panel 103. Specifically, the door panel 103 is fixed to the first connector (the mounting bracket of the hard disk module 1) by a limiting post 106, and the movable member 102 is slidably connected to the front end face of the door panel 103.

[0069] In some embodiments, the door panel 103 is provided with a slide groove 1031, and the movable member 102 can slide along the slide groove 1031 to drive the push rod 101 to move in a first direction. When the movable member 102 is released from its limit, it can be manually moved to slide, so that the movable member 102 drives the push rod 101 to retract.

[0070] For ease of assembly, the door panel 103 is also provided with a receiving groove 1032. Correspondingly, the movable part 102 includes a toggle part 1021 and a connecting part 1022. The connecting part 1022 passes through the slide groove 1031, and the toggle part 1021 is provided in the receiving groove 1032. In this way, by toggle the toggle part 1021, the toggle part 1021 slides in the receiving groove 1032, and the connecting part 1022 slides in the slide groove 1031.

[0071] To facilitate the linkage between the movable part 102 and the push rod 101, the connecting assembly 100 also includes a fixed seat 104, which is fixedly connected to the push rod 101. The movable part 102 is provided with a protruding claw 1023. The protruding claw 1023, the connecting part 1022, and the actuating part 1021 are an integral structure, such as an integral injection molded structure. The protruding claw 1023 abuts against the fixed seat 104. By actuating the movable part 102, the fixed seat 104 and the push rod 101 are driven to move in the first direction.

[0072] It should be noted that, in order to facilitate the automatic reset of the push rod 101, the connecting assembly 100 also includes an elastic element 105, which is used to provide an elastic force to the push rod 101 so that the push rod 101 tends to extend out of the first connecting member.

[0073] In some embodiments, the elastic element 105 is specifically a spring element, which is sleeved on the push rod 101. The push rod 101 is provided with a first limiting protrusion 1051, and the two ends of the spring element respectively abut against the first limiting protrusion 1051 and the second limiting protrusion 1052 in the first connector (the fixing frame of the hard disk module 1).

[0074] Of course, depending on actual needs, the number of movable part 102, push rod 101, fixed seat 104, and elastic part 105 are all two.

[0075] In this way, during actual use, when there is a need to disassemble the hard drive module 1, after the control board 300 controls the lock head limit rod 2021 to rotate 90°, the two movable parts 102 on the door panel 103 can be pulled and the two push rods 101 can be driven to close together (retract movement), thus finally unlocking the hard drive module 1 from the chassis 2; when there is a need to install the hard drive module 1, the hard drive module 1 is pushed into the chassis 2. At this time, the two elastic parts 105 are in a compressed state. Under the elastic force of the elastic parts 105, the two push rods 101 tend to extend out of the first connecting part. When the hard drive module 1 is pushed all the way, the two push rods 101 extend out of the fixing frame of the hard drive module 1 under the action of the elastic parts 105 and insert into the slot of the chassis 2, thus locking with the chassis 2.

[0076] In some embodiments, in order to facilitate the automatic ejection of the hard disk module 1, the unlocking control device 10 further includes an ejection component 500. One end of the ejection component 500 is connected to the control board 300, and the other end is used to abut against the first connector (hard disk module 1). The ejection component 500 can provide elastic force to the hard disk module 1 so that the hard disk module 1 has a tendency to eject the second connector in the second direction.

[0077] The ejection assembly 500 can consist of at least two springs, which are positioned between the control board 300 and the hard drive module 1. One end of each spring is fixedly connected to the control board 300, and the other end abuts against the hard drive module 1. In this way, when the hard drive module 1 is unlocked from the chassis 2, the ejection assembly 500 can automatically eject the hard drive module 1 from the chassis 2.

[0078] It should be noted that the control board 300 is equipped with a hard disk connector, and the hard disk module 1 is detachably connected to the hard disk connector. After the hard disk module 1 is pushed into the chassis 2, the hard disk module 1 connects to the hard disk connector to achieve communication with the circuit board; after the hard disk module 1 is ejected from the chassis 2, the hard disk module 1 disconnects from the hard disk connector on the circuit board.

[0079] In some embodiments, to facilitate unlocking in an emergency, the unlocking control device 10 further includes an emergency slider 600, which is slidably connected to the first connector (the mounting bracket of the hard disk module 1). For example, a sliding groove can be provided on the mounting bracket of the hard disk module 1. By moving the emergency slider 600, the emergency slider 600 can slide in the sliding groove on the mounting bracket of the hard disk module 1. Correspondingly, the push rod 101 is provided with an inclined surface 1011. By pushing the emergency slider 600, the emergency slider 600 contacts the inclined surface 1011, causing the push rod 101 to retract.

[0080] Specifically, the inclined surface 1011 is located on the side of the push rod 101 near the control board 300. When the power is off and the infrared remote control cannot be used to unlock, the chassis cover can be opened, and the emergency slide 600 can be moved to the side away from the control board 300. After the emergency slide 600 contacts the inclined surface 1011 of the push rod 101, the push rod 101 will retract, thereby unlocking.

[0081] The unlocking control device 10 provided in this application embodiment first receives a specific unlocking command from the user through the unlocking command receiving module 400, then controls the lock head limit rod 2021 of the rotation control module 200 to rotate through the control board 300, and finally, through mechanical transmission, that is, the moving part 102 drives the push rod 101 to move along the first direction, so that the first connecting part and the second connecting part switch from the locked state to the unlocked state.

[0082] The specific unlocking process is as follows:

[0083] Step 1: The infrared emitting module approaches the infrared receiving panel 401 on the mounting bracket of the hard disk module 1 and emits an infrared signal of a specific wavelength and intensity;

[0084] Step 2: The infrared receiving panel 401 receives the infrared signal of that specific wavelength and intensity;

[0085] Step 3: The infrared reflector 402 reflects the infrared signal of a specific wavelength and intensity to the infrared lamp light guide column 403;

[0086] Step 4: The infrared light guide column 403 transmits the infrared signal of a specific wavelength and intensity to the infrared photosensitive device 404;

[0087] Step 5: The infrared photosensitive device 404 receives the infrared signal of that specific wavelength and intensity;

[0088] Step 6: The control board 300 processes the infrared signal of this specific wavelength and intensity;

[0089] Step 7: After processing the signal, the control board 300 supplies power to the electronic lock 202 control device;

[0090] Step 8: After the lock head limit rod 2021 of the electronic lock 202 control device is powered on, it rotates 90° to release the limit on the moving part 102;

[0091] Step 9: Manually move the two movable parts 102 so that the two movable parts 102 respectively drive the two push rods 101 to retract in the first direction, thereby unlocking the first connector and the second connector;

[0092] Step 10: Release the elastic force of the ejector component 500 to eject the hard drive module 1. At this time, the hard drive module 1 can be removed from the chassis 2 along the second direction.

[0093] When the hard drive module 1 and the chassis 2 are locked, the two push rods 101 extend, the two movable parts 102 return to their original positions, the lock head limit rod 2021 of the electronic lock 202 extends and restricts the movement of the movable parts 102, and the hard drive module 1 remains locked to the chassis 2.

[0094] The specific locking process is as follows:

[0095] Step 1: Push hard drive module 1 into chassis 2;

[0096] Step 2: Pop-up component 500 is compressed;

[0097] Step 3: The two push rods 101 extend into the chassis 2 under the elastic force of the elastic element 105, and remain locked with the chassis 2 when the hard disk module 1 is pushed to the bottom of the chassis 2.

[0098] When the unlocking control device 10 is applied to the external hard drive module 1, it achieves a semi-automatic unlocking operation through the linkage of the unlocking command receiving module 400, control board 300, rotation control module 200 and connecting component 100, thereby preventing the hard drive module 1 from being deliberately disassembled and achieving the purpose of anti-theft. In addition, the unlocking control device 10 adds an automatic ejection component 500 to the mechanical transmission control, which improves the security of the external hard drive module 1 while also ensuring the convenience of unlocking.

[0099] This application provides a server including a chassis 2 and a hard disk module 1 detachably connected to the chassis 2, and also includes an unlocking control device 10 as described in the above specific embodiments. The unlocking control device 10 is located on the hard disk module 1, and the hard disk module 1 and the chassis 2 are unlocked through the unlocking control device 10. Other parts of the server can be referred to in the prior art, and will not be elaborated here.

[0100] In some embodiments, the chassis 2 is provided with a slot, and when the push rod 101 disengages from the slot, the hard disk module 1 is unlocked from the chassis 2.

[0101] In actual use, when there is a need to disassemble hard drive module 1, the infrared emitting module needs to be brought close to the infrared receiving panel 401 fixed on the hard drive bracket. When the infrared photosensitive device 404 fixed on the server receives an infrared signal of a specific wavelength and intensity, it will control the locking limit lever 2021 to rotate 90°. At this time, the two movable parts 102 can be moved to drive the two push rods 101 to retract, ultimately unlocking hard drive module 1 from chassis 2. Then, under the action of the elastic element 105 between hard drive module 1 and circuit board, hard drive module 1 automatically pops out, and hard drive module 1 is disassembled.

[0102] The above-described configuration improves the security and ease of unlocking of the external hard drive module 1. Of course, the unlocking control device 10 provided in this embodiment can also be applied to other devices with similar anti-theft requirements, making it widely applicable.

[0103] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
