[0037] It can be understood that when the fastening device 300 is in the unlocked position, the fastening device 300 is disconnected from at least one of the chassis 100 and the hard disk 200, specifically, when the hard disk 200 needs to be pulled out of the mounting cavity 110, the fastening device 300 can be first disconnected from the chassis 100 and the hard disk 200, so that the hard disk 200 and the chassis 100 can be separated, in this structure, the unlocked position specifically refers to the position of the fastening device 300 when it is disconnected from the chassis 100 and the hard disk 200. Alternatively, when the hard disk 200 needs to be pulled out of the mounting cavity 110, the fastening device 300 can be first disconnected from the chassis 100, so that the hard disk 200 can be separated from the chassis 100 through the fastening device 300, in this structure, the unlocked position specifically refers to the position of the fastening device 300 when it is disconnected from the chassis 100. In addition, when the hard disk 200 needs to be pulled out of the mounting cavity 110, the fastening device 300 can be first disconnected from the hard disk 200, so that the hard disk 200 can be simultaneously separated from the fastening device 300 and the chassis 100, in this structure, the unlocked position specifically refers to the position of the fastening device 300 when it is disconnected from the hard disk 200.

[0038] Referring to Figures 1 to 5 In some embodiments, the chassis 100 has a first connecting portion 120, the first connecting portion 120 is provided with a first connecting hole 121, the hard disk 200 has a second connecting portion 210, the second connecting portion 210 is provided with a second connecting hole 211, when the hard disk 200 is inserted into the mounting cavity 110, the first connecting hole 121 is aligned with the second connecting hole 211; when the fastening device 300 is in the locked position, the fastening device 300 is fixedly installed in the first connecting hole 121 and the second connecting hole 211, when the fastening device 300 is in the unlocked position, the fastening device 300 is disconnected from at least one of the first connecting hole 121 and the second connecting hole 211.

[0039] By adopting the above structure, the first connecting part 120 is arranged on the case 100, and the second connecting part 210 is arranged on the hard disk 200. The first connecting part 120 is provided with the first connecting hole 121, and the second connecting part 210 is provided with the second connecting hole 211. Therefore, the installation of the fastening device 300 can be facilitated. The fastening device 300 can be fixedly installed in the first connecting hole 121 and the second connecting hole 211, so as to realize the fixed connection with the case 100 and the hard disk 200. When the hard disk 200 is inserted, the hard disk 200 is first inserted into the installation cavity 110, and the first connecting hole 121 is aligned with the second connecting hole 211. Then, the fastening device 300 is fixedly installed in the first connecting hole 121 and the second connecting hole 211. At this time, the fastening device 300 is located at the locking position. When the control module receives the locking position signal sent by the detection module 400, the read-write function of the data processing module can be activated. Therefore, the read-write operation on the hard disk 200 can be performed after the hard disk 200 is safely inserted. When the hard disk 200 is pulled out, the fastening device 300 needs to be pulled out from at least one of the first connecting hole 121 and the second connecting hole 211, so that the fastening device 300 is located at the unlocking position. When the control module receives the unlocking position signal sent by the detection module 400, the current read-write operation of the data processing module can be forcibly terminated. Therefore, the read-write operation has been completed when the hard disk 200 is pulled out from the installation cavity 110 subsequently. Therefore, the risk that the read-write operation is abnormal, the data is disordered or lost and the like due to the direct pulling out of the hard disk 200 in the read-write process can be reduced. Therefore, the hard disk 200 can be safely pulled out, and the data of the hard disk 200 can be protected.

[0040] With reference to Figures 1 to 5 In some embodiments, the fastening device 300 has a threaded part 310 and an abutting part 320. The first connecting hole 121 of the first connecting part 120 is provided with an internal thread matched with the threaded part 310. The second connecting part is provided with a limiting part (not marked in the figure) capable of cooperating with the abutting part 320. When the fastening device 300 is located at the locking position, the threaded part 310 is threadedly installed in the internal thread, and the abutting part 320 abuts against the side surface of the limiting part away from the threaded part 310.

[0041] In the above structure, the fastening device 300 has a threaded portion 310 and an abutting portion 320, when the fastening device 300 is in the locked position, i.e. the fastening device 300 is fixedly connected between the case 100 and the hard disk 200, the threaded portion 310 of the fastening device 300 is screwed into the first connecting hole 121 of the first connecting portion 120, and the abutting portion 320 of the fastening device 300 abuts against the side surface of the limiting portion away from the threaded portion 310, at this time, the fastening device 300 can be fixedly connected with the first connecting portion 120 through the threaded portion 310, and the second connecting portion 210 is limited by the abutting portion 320, so that the second connecting portion 210 is clamped between the first connecting portion 120 and the abutting portion 320, thereby realizing the fixed connection between the first connecting portion 120 and the second connecting portion 210, i.e. the fixed connection between the case 100 and the hard disk 200. When it is needed to pull out the hard disk 200 from the mounting cavity 110, the fastening device 300 needs to be twisted first, and the threaded portion 310 is screwed out of the first connecting hole 121, so that the fastening device 300 is disconnected with the first connecting portion 120 and moves to the unlocked position, at this time, the detection module 400 can feed back the detected unlocking position signal to the control module, and the current read-write operation of the data processing module is forcibly terminated through the control module, thereby reducing the risk of abnormal read-write operation, data disorder or loss caused by directly pulling out the hard disk 200 during the read-write process, and facilitating the safe pulling out of the hard disk 200, which is beneficial to the protection of the data of the hard disk 200.

[0042] It can be understood that the first connecting hole 121 of the first connecting portion 120 is provided with an internal thread matched with the threaded portion 310, and the second connecting portion is provided with a limiting portion capable of cooperating with the abutting portion 320, only for Figures 1 to 5In some embodiments, the second connecting hole 211 of the second connecting part 210 can be provided with an internal thread matched with the threaded part 310, and the first connecting part 120 can be provided with a limiting part capable of abutting against the abutting part 320. When the fastening device 300 is in the locking position, the threaded part 310 is screwed into the second connecting hole 211, and the abutting part 320 abuts against the side surface of the limiting part away from the threaded part 310. At this time, the fastening device 300 can be fixedly connected with the second connecting part 210 through the threaded part 310, and the first connecting part 120 can be limited by the abutting part 320, so that the first connecting part 120 is clamped between the second connecting part 210 and the abutting part 320, thereby realizing the fixed connection between the first connecting part 120 and the second connecting part 210, i.e., the fixed connection between the case 100 and the hard disk 200. When it is necessary to pull out the hard disk 200 from the mounting cavity 110, the fastening device 300 needs to be screwed first, and the threaded part 310 is screwed out of the second connecting hole 211, so that the fastening device 300 is disconnected from the second connecting part 210 and moves to the unlocking position. At this time, the detection module 400 can feed back the detected unlocking position signal to the control module, and forcibly terminate the current read-write operation of the data processing module through the control module, thereby reducing the risk of abnormal read-write operation, data disorder or loss caused by directly pulling out the hard disk 200 during read-write process, and facilitating safe pulling out of the hard disk 200, which is beneficial to protecting the data of the hard disk 200.

[0043] It can be understood that, with reference to Figures 1 to 5 When the limiting part is located in the second connecting part 210, the limiting part can be specifically provided as a side edge of the second connecting hole 211 away from the first connecting part 120. Of course, in addition thereto, the limiting part can also be provided as a structure protruding inwardly relative to the inner wall of the second connecting hole 211. The same applies to when the limiting part is located in the first connecting part 120. The limiting part can be provided as a side edge of the first connecting hole 121 away from the second connecting part 210, or can also be provided as a structure protruding inwardly relative to the inner wall of the first connecting hole 121.

[0044] It can be understood that the fastening device 300 can specifically adopt a structure such as a stud or a screw, which can not only reduce the cost of the fastening device 300, but also facilitate the procurement of the fastening device 300. Of course, the specific selection of the fastening device 300 is not limited in the present application.

[0045] It can be understood that, in addition to the above structure, in some embodiments, when the fastening device 300 is in the locked position, the fastening device 300 can also be directly screwed into the first connecting hole 121 and the second connecting hole 211, that is, the fastening device 300 is screwed with the first connecting part 120 and the second connecting part 210 at the same time, so as to realize the fixed connection of the case 100 and the hard disk 200. In this structure, the fastening device 300 can specifically adopt a screw rod, of course, a stud or a screw can also be adopted, and the present application does not make specific limitation thereto.

[0046] It can be understood that, in addition to the above screw structure, in some embodiments, the fastening device 300 can also adopt a clamping structure, that is, the fastening device 300 can be clamped or separated from the first connecting part 120 and the second connecting part 210 at the same time through clamping, for example, in some embodiments, the threaded part 310 described above can be replaced by an elastic clamping block. When the fastening device 300 is inserted into the first connecting hole 121 and the second connecting hole 211, the elastic clamping block can move through the first connecting hole 121 and the second connecting hole 211 along with the fastening device 300. When the fastening device 300 is in the locked position, the elastic clamping block can pass out of the first connecting hole 121 and the second connecting hole 211, and one of the elastic clamping block and the abutting part 320 abuts against one side edge of the first connecting hole 121 away from the second connecting part 210, and the other abuts against one side edge of the second connecting hole 211 away from the first connecting part 120. In addition, an elastic clamping groove can also be formed on the fastening device 300. When clamped, the first connecting part 120 and the second connecting part 210 can be clamped in the elastic clamping groove. The inner wall of the elastic clamping groove can clamp and fix the first connecting part 120 and the second connecting part 210 under the action of elasticity. When disassembled, the fastening device 300 can be directly pulled out. Of course, in addition to the above, the fastening device 300 can also adopt other structures to realize the connection between the case 100 and the hard disk 200, and the present application does not make specific limitation thereto.

[0047] Referring to Figures 1 to 7 In some embodiments, the detection module 400 is a contact switch electrically connected with the control module, and the contact switch is arranged on one side of the first connecting part 120 away from the second connecting part 210. When the fastening device 300 is in the locked position, the fastening device 300 abuts against the contact switch, and the contact switch can send a locked position signal to the control module. When the fastening device 300 is in the unlocked position, the fastening device 300 is separated from the contact switch, and the contact switch can send an unlocked position signal to the control module.

[0048] In the above structure, by setting the detection module 400 as a contact switch, the position of the fastening device 300 can be conveniently and accurately detected. After the hard disk 200 is inserted into the mounting cavity 110, the fastening device 300 is sequentially mounted in the first connecting hole 121 and the second connecting hole 211 and moved to press against the contact switch, that is, the fastening device 300 is mounted in place and has reached the locking position. At this time, the contact switch can send a locking position signal to the control module, and the control module activates the read-write function of the data processing module according to the received locking position signal, so that the data processing module starts to perform the read-write operation on the hard disk 200. When the hard disk 200 is pulled out of the mounting cavity 110, the fastening device 300 needs to be disassembled first, so that the fastening device 300 can reach the unlocking position and be separated from the contact switch. At this time, the contact switch can send an unlocking position signal to the control module, and the control module forcibly terminates the current read-write operation of the data processing module according to the received unlocking position signal, thereby reducing the risk of abnormal read-write operation, data disorder or loss caused by directly pulling out the hard disk 200 during the read-write process, and facilitating safe pulling out of the hard disk 200, which is beneficial to protecting the data of the hard disk 200.

[0049] It can be understood that the detection module 400 is a contact switch, which is only an exemplary description of the present application. In some embodiments, the detection module 400 can also be set as a non-contact proximity switch or an infrared distance sensor, and the present application does not make specific limitations thereto.

[0050] Referring to Figures 1 to 7 In some embodiments, the mounting cavity 110 is provided with a mounting frame 130, and the contact switch is mounted on the mounting frame 130. The first connecting portion 120 is located above the mounting frame 130. When the hard disk 200 is inserted into the mounting cavity 110, the second connecting portion 210 is located above the first connecting portion 120, and the second connecting hole 211 and the first connecting hole 121 are arranged in the up-down direction.

[0051] In the above structure, the mounting frame 130 can facilitate the installation of the contact switch. By setting the first connecting portion 120 above the mounting frame 130 and setting the second connecting portion 210 above the first connecting portion 120, the fastening device 300 can be sequentially inserted into the second connecting hole 211 and the first connecting hole 121 from top to bottom and moved close to the contact switch during installation. During disassembly, the fastening device 300 can be moved from bottom to top to move away from the first connecting hole 121 and the second connecting hole 211 and move away from the contact switch. This structure not only facilitates the disassembly and installation of the fastening device 300, but also limits the contact switch inside the mounting cavity 110 and below the first connecting portion 120, thereby protecting the contact switch.

[0052] It can be understood that, referring toFigures 1 to 5 When the hard disk 200 is inserted into the installation cavity 110, the second connecting portion 210 abuts against the upper surface of the first connecting portion 120, thereby enabling the second connecting hole 211 to directly communicate with the first connecting hole 121 in the up-down direction, making the installation and dismounting of the fastening device 300 more convenient, and in addition, the first connecting portion 120 can provide support for the second connecting portion 210, thereby avoiding the hard disk 200 from continuously moving downward after being inserted into place.

[0053] With reference to Figures 1 to 5 In some embodiments, the top wall of the case 100 is provided with an installation opening 111 communicating with the installation cavity 110, and the first connecting portion 120 is arranged on the top wall of the case 100 and located at one side of the installation opening 111; the top wall of the case 100 is provided with four installation columns 140 extending downward to the installation cavity 110, and the mounting rack 130 is mounted on all the installation columns 140 and arranged in a staggered manner with the installation opening 111.

[0054] In the above structure, by arranging the first connecting portion 120 at one side of the installation opening 111 and arranging the mounting rack 130 in a staggered manner with the installation opening 111, interference or collision caused by the first connecting portion 120 and the mounting rack 130 during the insertion or extraction of the hard disk 200 can be avoided, thereby protecting the hard disk 200 and facilitating the safe insertion and extraction of the hard disk 200. By arranging four installation columns 140 extending downward to the installation cavity 110 on the top wall of the case 100, the mounting of the mounting rack 130 can be facilitated.

[0055] It can be understood that the number of the above-mentioned installation columns 140 is four, which is only an exemplary description of the present application, and in order to facilitate the mounting of the mounting rack 130, the number of the installation columns 140 can be one, two, three, five or more, which is not limited in the present application.

[0056] It can be understood that the mounting rack 130 is mounted on the installation column 140, specifically, the mounting rack 130 can be mounted by screws, bolts and other fasteners. In addition, the mounting rack 130 can also be mounted on the installation column 140 by a clamping structure, which is not limited in the present application.

[0057] With reference to Figures 1 to 7In some embodiments, the contact switch comprises a support base 410, a pressing piece 420, an elastic piece 430, a first trigger (not shown) and a second trigger (not shown). The support base 410 is arranged on the mounting frame 130 and has a limiting hole 411. The pressing piece 420 is movably arranged in the limiting hole 411 and can abut against the lower edge of the limiting hole 411. The pressing piece 420 is located below the first connecting hole 121 or extends upward into the first connecting hole 121. The elastic piece 430 is arranged on the mounting frame 130 or the support base 410 and is located below the pressing piece 420 and abuts against the pressing piece 420. The first trigger is arranged on the mounting frame 130 and is electrically connected to the control module. The second trigger is arranged on the elastic piece 430 and can move towards or away from the first trigger relative to the mounting frame 130. When the fastening device 300 moves downward relative to the mounting frame 130 to the locked position, the fastening device 300 can abut against the pressing piece 420 and push the second trigger to abut against the first trigger downward. The first trigger can send a locked position signal to the control module. When the fastening device 300 moves upward relative to the mounting frame 130 to the unlocked position, the elastic piece 430 can push the pressing piece 420 to move upward and drive the second trigger to move upward away from the first trigger. The first trigger can send an unlocked position signal to the control module.

[0058] By adopting the above structure, when the fastening device 300 is installed, the fastening device 300 can be installed in the second connecting hole 211 and the first connecting hole 121 in sequence from top to bottom. In this process, the fastening device 300 can abut against the pressing piece 420 and push the pressing piece 420 to move downward, and can also push the second trigger on the elastic piece 430 to move downward to abut against the first trigger. At this time, the fastening device 300 reaches the locked position, and the first trigger can send a locked position signal to the control module after contacting the second trigger, so that the control module activates the read-write function of the data processing module. Thus, the read-write operation on the hard disk 200 can be performed after the hard disk 200 is safely inserted. When the hard disk 200 is pulled out, the fastening device 300 is separated from the first connecting hole 121 and the second connecting hole 211 from bottom to top. In this process, the fastening device 300 can move upward and separate from the pressing piece 420. The elastic piece 430 can be elastically reset and push the pressing piece 420 to move upward and reset, and also drive the second trigger to move upward away from the first trigger. The first trigger can send an unlocked position signal to the control module after separating from the second trigger, so that the control module forcibly terminates the current read-write operation of the data processing module. Thus, the risk of read-write operation abnormality, data disorder or loss caused by directly pulling out the hard disk 200 during the read-write process can be reduced, and the hard disk 200 can be safely pulled out, which is beneficial to protecting the data of the hard disk 200.

[0059] It can be understood that the above-mentioned locking position signal and unlocking position signal can be a level signal, for example, when the second trigger portion abuts against the first trigger portion, the first trigger portion can generate a high level signal and feed back the high level signal to the control system, and when the second trigger portion is away from the first trigger portion, the first trigger portion can generate a low level signal and feed back the low level signal to the control system.

[0060] With reference to Figures 1 to 7 In some embodiments, the elastic member 430 can be specifically a metal spring, the second trigger portion is arranged on the lower surface of the spring, or the lower surface of the spring is directly used as the second trigger portion, so that the spring can be deformed downward when subjected to a downward extrusion force, so that the second trigger portion moves downward to approach and abut against the first trigger portion, and at this time, the first trigger portion can send a locking position signal to the control module. When the downward extrusion force is cancelled, the spring can be reset upward and drive the second trigger portion to move upward away from the first trigger portion and separate from the first trigger portion, and at this time, the first trigger portion can send an unlocking position signal to the control module.

[0061] It can be understood that the elastic member 430 can be arranged as a compression spring or other elastic structure in addition to being arranged as a metal spring, which is not limited in the utility model.

[0062] In some embodiments, the data processing module and the hard disk 200 are electrically connected with a switch module, the switch module is electrically connected with the control module, the control module can control the switch module to be connected according to the locking position signal, and activate the read-write function of the data processing module; or the control module can forcibly terminate the current read-write operation of the data processing module according to the unlocking position signal, and then control the switch module to be disconnected.

[0063] By adopting the above structure, after the hard disk 200 is inserted, the control module can first control the switch module to be connected, so as to establish a data connection between the data processing module and the hard disk 200, and then activate the read-write function of the data processing module, so that the data processing module can perform the read-write operation on the hard disk 200, thereby realizing the safe insertion of the hard disk 200. Before the hard disk 200 is pulled out, the control module can first forcibly terminate the current read-write operation of the data processing module, and then control the switch module to be disconnected, so as to disconnect the data connection between the data processing module and the hard disk 200, thereby making the pulling out of the hard disk 200 more secure, and the structure can pull out the hard disk 200 without the need to power off the electronic elements in the case 100, thereby facilitating the use of the network camera base station supporting the safe insertion and pulling out of the hard disk.

[0064] It can be understood that the switch module can be specifically a switch circuit or other electronic elements capable of realizing the on-off of the circuit.

[0065] In some embodiments, the network camera base station supporting the hard disk safe plug and unplug further comprises a reminding module, which is arranged in the case 100 and electrically connected with the control module. When the data processing module starts to perform the read-write operation, the control module can control the reminding module to send the first prompt information; when the switch module is disconnected, the control module can control the reminding module to send the second prompt information.

[0066] In the above structure, by adding the reminding module, when the hard disk 200 is inserted, the fastening device 300 is first located at the locking position, so that the case 100 is fixedly connected with the hard disk 200. At this time, the detection module 400 can send a locking position signal to the control module. The control module can first control the switch module to be connected, and then activate the read-write function of the data processing module, and control the reminding module to send the first prompt information when the data processing module starts to perform the read-write operation on the hard disk, so as to remind the user that the data processing module starts to perform the read-write operation on the hard disk. When the hard disk 200 is pulled out, the fastening device 300 needs to be located at the unlocking position, so that the fastening device 300 is disconnected with at least one of the case 100 and the hard disk 200. At this time, the detection module 400 can send an unlocking position signal to the control module. The control module can first forcibly terminate the current read-write operation of the data processing module, then control the switch module to be disconnected, and control the reminding module to send the second prompt information after the switch module is disconnected, so as to prompt the user that the hard disk 200 can be safely pulled out. As can be seen, the setting of the reminding module can prompt the user, improve the user experience, and further improve the safety of the insertion and pulling out of the hard disk 200.

[0067] In some embodiments, the reminding module is a voice broadcast module.

[0068] In the above structure, by setting the reminding module as the voice broadcast module, the user can be prompted by voice broadcast, so that the first prompt information and the second prompt information sent by the reminding module can be more clear and explicit, which is beneficial to further improve the user experience and improve the safety of the insertion and pulling out of the hard disk 200.

[0069] It can be understood that the voice broadcast module can specifically adopt a buzzer.

[0070] It can be understood that the reminding module can be a voice broadcast module, and can also be set as a light-emitting module, such as an LED indicator.

[0071] The embodiments of the utility model are described in detail above combined with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the utility model.
