Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of servers, and particularly relates to an intrusion detection device and a server. BACKGROUND
[0002] With the development of social economy, especially with the development of artificial intelligence technology, the demand for IT equipment such as servers has significantly increased, and therefore higher demands are put forward for servers.
[0003] In the related art, in order to prevent the server case from being opened by external force without authorization, a device for detecting physical intrusion of the case of the server system is usually provided. The current intrusion detection of the server usually adopts two different ways: one is server self-checking, which detects the state of the case cover by installing a press switch in the server case, but this way can only detect in the power-on state of the server, and cannot identify and record the opening state of the case in the offline or power-off state of the server. The other is to paste a tamper-evident label at the joint of the case cover to judge whether there is physical intrusion, which is simple and low in cost. However, this way can only record the event of opening the cover once, and the label may be forged or not damaged by other methods, so that it cannot accurately judge whether there are multiple opening actions. SUMMARY
[0004] The present application provides an intrusion detection device and a server to at least solve the problem of power-off recording and multiple recording in the related art.
[0005] The present application provides an intrusion detection device, which comprises a base, a pressure rod, a counting structure and a gear structure. The base is arranged in a case, and the base is provided with a contact electrically connected with the case. The pressure rod is movably arranged on the base and abuts against a cover of the case to trigger the contact. The counting structure is rotatably arranged on the base. The gear structure is arranged on the pressure rod to drive the counting structure to count under the driving of the pressure rod.
[0006] The present application further provides a server, which comprises a case and the above-mentioned intrusion detection device. The intrusion detection device is arranged in the case.
[0007] Through the intrusion detection device and the server of the application, the server power-on state can be checked by the abutment of the pressing rod and the box cover, and the triggering of the contact connected with the case. In addition, since the device is provided with a rotating counting structure and a gear structure on the pressing rod, the pressing rod can drive the gear structure to count the counting structure after each opening of the box cover, so as to realize the physical counting of the server opening cover. Through the combination of physical counting and server power-on counting, not only the case opening record and the opening times record in the power-off state can be solved, but also the opening times of the case can be more accurately determined through the double verification mechanism of physical counting and server power-on counting, especially in the offline state, the potential physical intrusion behavior can be effectively identified through the overlapping verification, and the security protection ability of the server is improved.

[0031] In order for those skilled in the art to better understand the scheme of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.
[0032] Figure 1 A structural schematic diagram of an intrusion detection device provided by an embodiment of the present application. Figure 2 For Figure 1 A partially exploded structural schematic diagram of the intrusion detection device shown.
[0033] As Figure 1 The intrusion detection device 100 provided by the embodiment of the present application is used in a server. The server includes a case and the intrusion detection device 100. The intrusion detection device 100 is arranged in the case. The cover of the case abuts against the intrusion detection device 100.
[0034] As Figure 2As shown, in some possible implementations, the intrusion detection device 100 includes a base 10, a pressure rod 20, a counting structure 30, and a dial tooth structure 40. The base 10 is arranged in a case. The base 10 is provided with a contact 11 electrically connected to the case. The pressure rod 20 is movably arranged on the base 10 and abuts against a case cover of the case to trigger the contact 11. The counting structure 30 is rotatably arranged on the base 10. The dial tooth structure 40 is arranged on the pressure rod 20 to dial the counting structure 30 to count under the driving of the pressure rod 20.
[0035] Through the abutment between the pressure rod 20 and the case cover, the device can trigger the contact 11 electrically connected to the case immediately when the case cover is opened and closed again, for real-time detection, to ensure that any unauthorized opening of the case can be quickly identified when the server is powered on, and to achieve self-checking of the case cover of the server when the case cover is removed.
[0036] In addition, since the device is provided with the rotatable counting structure 30 and the dial tooth structure 40 arranged on the pressure rod 20, the number of times the case is opened can still be recorded even in the power-off or offline state of the server, supporting offline detection of physical intrusion and making up for the deficiency that self-checking of the case cover cannot be recorded in the power-off state. Each time the case cover is opened and closed again, the pressure rod 20 can drive the dial tooth structure 40 to dial the counting structure 30 to count, achieving physical counting of the removal of the case cover of the server.
[0037] Unlike the conventional anti-removal label that can only record one opening event, the device can record multiple opening events of the case through the counting structure 30, can provide more detailed records of the removal of the case cover, and is particularly suitable for servers that need to be frequently maintained. At the same time, the physical counting structure 30 is difficult to counterfeit, and compared with the anti-removal label that is easy to replace or counterfeit, the device provides higher security and reliability.
[0038] Through the combination of physical counting and server power-on self-checking counting, not only can the problem of recording the opening of the case and the problem of recording the number of times the case is opened in the power-off state be solved, but also the number of times the case cover is opened can be more accurately determined through the double verification mechanism of physical counting and server power-on self-checking counting, improving the accuracy of detection, especially in the offline state, potential physical intrusion behavior can be effectively identified through overlapping verification, improving the security protection capability of the server and reducing the risk of data leakage and equipment damage.
[0039] At the same time, the device structure is relatively simple and easy to integrate with existing server systems, without the need for large-scale modification of existing equipment. The intrusion detection device 100 has no electronic components, is completely immune to network attacks, and improves security.
[0040] In some possible implementations, the contact 11 is electrically connected to the chassis through the cable 111, thereby being electrically connected to a mainboard in the chassis and providing a detection signal to a baseboard management controller (BMC).
[0041] Figure 3 For Figure 1 A structural schematic view of a base of the intrusion detection device shown in FIG. 1. Figure 4 For Figure 3 A sectional view of the base shown in FIG. 2.
[0042] As Figure 3 shown in FIG. 3, in some possible implementations, the base 10 is provided with a sleeve 12, the sleeve 12 is provided with a pressing rod cavity 121, the pressing rod 20 is movably arranged in the pressing rod cavity 121, and the pressing rod 20 is provided with a reset spring 13 between the sleeve 12.
[0043] As Figure 4 shown in FIG. 4, in some possible implementations, the contact 11 is arranged on the bottom wall of the pressing rod cavity 121. Under the abutting action of the box cover, the pressing rod 20 can move towards the bottom of the pressing rod cavity 121 against the elastic force of the reset spring 13, thereby contacting the contact 11 and triggering the recording of the server box cover opening.
[0044] The sleeve 12 provides a fixed structure to accommodate the pressing rod 20, ensuring the stability and accuracy of the pressing rod 20 during movement, and can avoid the situation that the pressing rod 20 deviates or is stuck during movement, thereby improving the reliability of the device. At the same time, the pressing rod cavity 121 provides a closed space for the pressing rod 20, which can effectively protect the pressing rod 20 and the contact 11 from external environmental influences such as dust and moisture, thereby helping to prolong the service life of the device and maintain its sensitivity. The design of the sleeve 12 and the pressing rod cavity 121 limits the movement range of the pressing rod 20, reduces the false triggering caused by external vibration or other abnormal factors, and improves the accuracy of detection. The integrated design of the sleeve 12 and the pressing rod cavity 121 makes the entire device more compact, facilitating installation in limited chassis space without affecting the layout of other components.
[0045] The reset spring 13 is arranged to enable the pressing rod 20 to automatically return to the initial position after the cover is opened, thereby ensuring that the device can contact the contact 11 after each chassis cover is closed, so as to perform the next detection without manual intervention. Since the pressing rod 20 can quickly return to the initial position under the action of the reset spring 13, the response speed of the device is improved, which is helpful for real-time detection of the chassis opening state.
[0046] Figure 5 For Figure 1 A structural schematic view of a pressing rod of the intrusion detection device shown in FIG. 1. Figure 6 For Figure 1The structure diagram of the pressure rod of the intrusion detection device shown is inserted into the base. Figure 7 For Figure 6 The cross-sectional view of the pressure rod shown is inserted into the base.
[0047] As Figure 5 shown, in some possible implementations, the pressure rod 20 includes a trigger part 21, a limiting part 22, and an abutting part 23. The limiting part 22 connects the trigger part 21 and the abutting part 23.
[0048] As Figure 6 and Figure 7 shown, the trigger part 21 is arranged in the pressure rod cavity 121, and the trigger part 21 is used to contact the contact 11 to trigger the record of the server case cover opening. The abutting part 23 abuts against the case cover. The reset spring 13 is arranged between the limiting part 22 and the bottom wall of the pressure rod cavity 121.
[0049] The pressure rod 20 is divided into the trigger part 21, the limiting part 22, and the abutting part 23. Each part is focused on a specific function. The trigger part 21 is responsible for contacting the contact 11, the limiting part 22 ensures that the movement range of the pressure rod 20 is controlled, and the abutting part 23 directly contacts the case cover to help improve the efficiency and reliability of each function. Due to the separation of functions of each part and the controlled movement, the pressure rod 20 is less worn during use, prolonging the service life of the device.
[0050] The trigger part 21 is located in the pressure rod cavity 121, which ensures accurate docking with the contact 11, reduces the possibility of false triggering, and improves the accuracy of detection. The design of the limiting part 22 limits the movement range of the pressure rod 20 to prevent excessive displacement, which not only protects the pressure rod 20 and the contact 11, but also improves the durability of the device. The abutting part 23 directly contacts the case cover to ensure that the action can be immediately transmitted to other parts of the pressure rod 20 when the case cover is closed, improving the response speed and sensitivity of the device.
[0051] The reset spring 13 is located between the limiting part 22 and the bottom wall of the pressure rod cavity 121, providing an automatic reset function. After each opening of the case cover, the reset spring 13 pushes the pressure rod 20 back to the initial position, ready for the next detection, reducing manual intervention and improving the automation level of the device.
[0052] In some possible implementations, the contact 11 is a positive and negative spring contact pin, which triggers a signal when the positive and negative electrodes are connected. The trigger part 21 is a conductive column used to contact and connect the positive and negative spring contact pins.
[0053] In some possible implementations, the trigger part 21 is a copper conductive column to improve conductivity and ensure accurate signal recognition.
[0054] In some possible implementations, the contact 11 is also provided with a spacer 112. The spacer 112 is used to separate the reset spring 13 from the contact 11, preventing the reset spring 13 from contacting the contact 11 and causing signal misjudgment.
[0055] In some possible implementations, the base 10 is also provided with a fixed cover 14. The fixed cover 14 covers the pressing rod cavity 121. The fixed cover 14 is provided with a through hole 141. The abutting portion 23 is inserted into the through hole 141. The limiting portion 22 is arranged in the pressing rod cavity 121 and can abut against the fixed cover 14 under the action of the reset spring 13.
[0056] The fixed cover 14 covers the pressing rod cavity 121, providing additional protection for the pressing rod 20 and internal components, preventing dust, moisture and other external contaminants from entering the pressing rod cavity 121, thereby improving the durability and reliability of the device. The through hole 141 on the fixed cover 14 ensures the precise positioning of the abutting portion 23, limiting the movement range of the abutting portion 23, so that the device can more accurately respond to the opening action of the case cover, reducing the possibility of false triggering. The presence of the fixed cover 14 enhances the structural stability of the entire device, not only fixing the movement path of the pressing rod 20, but also providing a solid shell for the entire device, preventing direct impact on internal components by external forces.
[0057] The limiting portion 22 abuts against the fixed cover 14 under the action of the reset spring 13, providing a clear movement endpoint, preventing excessive displacement of the pressing rod 20, protecting internal components and improving the stability of the device. The reset spring 13 allows the limiting portion 22 to automatically return to the initial position after each action, and the abutment with the fixed cover 14 provides a clear reset position, ensuring that the device can quickly recover to a ready state after each cover opening, improving the continuity and reliability of detection. The design of the fixed cover 14 makes the components of the device more modular, facilitating disassembly and replacement. This design simplifies the maintenance process and reduces maintenance costs.
[0058] Figure 8 For Figure 1 Structure diagram of the rotating shaft of the counting structure of the intrusion detection device shown in FIG. 1. Figure 9 For Figure 1 Structure diagram of the counting disc of the counting structure of the intrusion detection device shown in FIG. 1.
[0059] As Figure 8 and Figure 9 In some possible implementations, the counting structure 30 includes a rotating shaft 31 and at least one counting disc 32. The counting disc 32 is rotatably arranged on the rotating shaft 31. The counting disc 32 can rotate on the rotating shaft 31 under the action of the ratchet structure 40 to achieve counting.
[0060] The counting disc 32 rotates on the rotating shaft 31 and can accurately record the number of times the case cover is opened. Each rotation of the counting disc 32 corresponds to an opening event driven by the dial tooth structure 40, ensuring the accuracy of the count. The mechanical counting structure 30 does not rely on electronic components, so it is not affected by the power state. Even in a power-off or offline state, the device can still work normally and record the number of times the cover is opened. The mechanical structure of the rotating shaft 31 and the counting disc 32 generally has high durability and can maintain stable performance over a long period of use, reducing maintenance requirements. This design can be easily integrated into existing intrusion detection devices without the need for major changes to the existing system.
[0061] Unlike one-time tamper-evident labels, the counting disc 32 can record multiple opening events and provide more detailed historical records. The counting disc 32 can typically be designed with scale markings or numerical markings so that the count result can be directly read. This visual recording method allows users to quickly understand the opening history of the case.
[0062] Figure 10 For Figure 1 Structure diagram of the counting disc of the counting structure of the intrusion detection device shown in FIG. 1.
[0063] As Figure 10 In some possible implementations, the counting disc 32 is provided with a carry tooth 321 and a plurality of dial teeth 322. The carry tooth 321 and the plurality of dial teeth 322 are arranged in sequence around the axis of the counting disc 32. The dial teeth 322 are used to rotate the counting disc 32 on the rotating shaft 31 under the drive of the dial tooth structure 40. The carry tooth 321 is used to rotate the counting disc 32 on the rotating shaft 31 under the drive of the dial tooth structure 40, and the next counting disc 32 can be rotated under the drive of the dial tooth structure 40 to achieve carry counting.
[0064] Specifically, when the counting disc 32 rotates one revolution, the dial tooth structure 40 sinks into the carry tooth 321, so that the dial tooth structure 40 can simultaneously drive the carry tooth 321 or the dial tooth 322 on the next counting disc 32 to advance one position, thereby completing the counting of multiple counting discs 32.
[0065] In some possible implementations, the counting disc 32 is provided with nine dial teeth 322 and one carry tooth 321. Thus, each counting disc 32 can perform decimal counting.
[0066] The arrangement of the carry teeth 321 allows the counting disc 32 to automatically carry over after reaching a certain number, similar to the carry mechanism in mechanical counters, enabling the counting structure 30 to record a larger range of values, suitable for application scenarios that require frequent recording. The presence of the dial teeth 322 ensures that each dialing accurately pushes the counting disc 32 to rotate one unit, improving the accuracy of counting and ensuring that each opening of the case cover is correctly recorded. Through the combination of carry teeth 321 and dial teeth 322, users can intuitively read the counting result and understand the opening history of the case, facilitating users to quickly judge the use of the device.
[0067] The sequential arrangement of the carry teeth 321 and the dial teeth 322 makes the rotation of the counting disc 32 smoother, reducing the possibility of jamming or jumping. This smooth operation improves the reliability and service life of the device. This design maintains the simplicity of the mechanical structure, easy to manufacture and maintain, while providing complex counting functions. Mechanical gear structures generally have high durability and can maintain stable performance over a long period of use, reducing maintenance requirements. Since it is a mechanical structure, the design of the carry teeth 321 and the dial teeth 322 does not require power driving, suitable for use in power-off environments.
[0068] Figure 11 For Figure 1 Figure 3 is a schematic diagram of the structure of the counting disc of the counting structure of the intrusion detection device shown in Figure 1.
[0069] As Figure 11 As shown in some possible implementations, the counting disc 32 is provided with a counting area 323. The counting area 323 is arranged around the outer periphery of the counting disc 32. The counting area 323 corresponds to the positions of the carry teeth 321 and the dial teeth 322, so that when the counting disc 32 rotates, counting is performed.
[0070] By arranging the counting area 323 on the outer periphery of the counting disc 32, the counting result can be directly read from the outside, improving visibility, and users can quickly view the current counting state without disassembling the device. By using the outer periphery space of the counting disc 32 to set the counting area 323, the limited space can be maximally utilized for information display. The outer periphery arranged counting area 323 can be marked by scales, numbers or colors, making the counting result clearer and easier to understand, facilitating users to quickly identify and understand the current counting information. Users can obtain information by simply observing the outer periphery counting area 323 without complex operations or tools, which improves user experience and operational convenience. Arranging the counting area 323 on the outer periphery can simplify the internal structure design and reduce the complexity of internal components, thereby reducing manufacturing and maintenance costs.
[0071] In some possible implementations, the counting area 323 is recorded in the form of a binary record coding disc.
[0072] The counting area 323 can be provided with four positions, each of which can be provided with a protrusion, the position of the protrusion being binary 1 and the position without the protrusion being binary 0. Through the cooperation of the four positions, the correspondence with the decimal 0 to 9 is realized.
[0073] The specific correspondence is: when the counting area value is 0000, the decimal is 0; when the counting area value is 0001, the decimal is 1; when the counting area value is 0010, the decimal is 2; when the counting area value is 0011, the decimal is 3; when the counting area value is 0100, the decimal is 4; when the counting area value is 0101, the decimal is 5; when the counting area value is 0110, the decimal is 6; when the counting area value is 0111, the decimal is 7; when the counting area value is 1000, the decimal is 8; and when the counting area value is 1001, the decimal is 9.
[0074] In some possible implementation manners, the counting structure 30 includes three counting discs 32. The three counting discs 32 are respectively a first counting disc 33, a second counting disc 34 and a third counting disc 35. The first counting disc 33, the second counting disc 34 and the third counting disc 35 can each count ten times, so as to cooperate with each other to realize three-bit counting of the counting structure 30 and one-thousand-time opening box recording. In combination with the binary recording form of the counting area 323, the rapid identification of the user is facilitated, and the information is also encrypted.

Figure 13 For Figure 1 The first structural schematic view of the reset member loaded into the counting disc of the counting structure of the intrusion detection device shown in FIG. 2. Figure 14 For Figure 1 The second structural schematic view of the reset member loaded into the counting disc of the counting structure of the intrusion detection device shown in FIG. 2.
[0076] As Figure 12 shown in FIG. 2, in some possible implementation manners, the counting disc 32 is provided with a reset tooth 324.
[0077] As Figure 13 shown in FIG. 2, the counting structure 30 further includes at least one reset member 36. The reset member 36 corresponds to the counting disc 32 one by one. The reset member 36 is arranged on the rotating shaft 31 and located on the side of the counting disc 32 provided with the reset tooth 324. The reset member 36 is used to abut against the reset tooth 324 under the driving of the rotating shaft 31, so as to drive the counting disc 32 to reset.
[0078] The combination of the reset member 36 and the reset tooth 324 enables the counter disc 32 to be reset under certain conditions. This design ensures that the counter disc 32 can be reset to the initial state when a predetermined count is reached or when necessary, preparing for a new counting period. The design of the reset member 36 and the reset tooth 324 is relatively simple, easy to maintain and replace, reducing maintenance costs and complexity.
[0079] Through the reset mechanism, counting errors caused by mechanical failure or misoperation can be effectively prevented. The reset function ensures that each counting period starts from a known initial state, improving the accuracy and reliability of counting. The reset member 36 is arranged on the rotating shaft 31, making the entire reset structure compact and not occupying additional space, suitable for use in environments with limited space. Mechanical reset structure generally has high reliability, does not depend on power or complex electronic control, and is suitable for use in various environmental conditions.

[0081] As Figure 15 shown in some possible implementations, the rotating shaft 31 is provided with a positioning slot 311. The reset member 36 is provided with a positioning tooth 361 and a reset portion 362. The positioning tooth 361 is arranged in the positioning slot 311 to drive the rotating shaft 31 to rotate the reset member 36. The reset portion 362 is used to abut against the reset tooth 324 when the reset member 36 rotates, thereby resetting the counter disc 32.
[0082] The cooperation of the positioning tooth 361 and the positioning slot 311 can fix multiple reset members 36 at a unified position, so that the rotating shaft 31 can drive multiple reset members 36 to rotate simultaneously when the rotating shaft 31 rotates, thereby resetting the counter disc 32 simultaneously.
[0083] The cooperation of the positioning tooth 361 and the positioning slot 311 ensures the accurate rotation of the reset member 36 under the drive of the rotating shaft 31. This accuracy enables the reset portion 362 to accurately contact the reset tooth 324, thereby achieving reliable reset operation. The positioning tooth 361 is embedded in the positioning slot 311, preventing the reset member 36 from slipping or mispositioning during rotation, thereby improving the stability and reliability of the reset operation. Through the combination of the positioning tooth 361 and the positioning slot 311, the reset member 36 can rotate synchronously with the rotating shaft 31, ensuring the coordination of the reset operation, so that the reset portion 362 can contact the reset tooth 324 at the appropriate time.
[0084] The design simplifies the structure of the reset mechanism, and the reset operation does not require additional control mechanisms or complex electronic components, reducing manufacturing and maintenance costs. The mechanical structure design generally has high durability, and the combination of the positioning teeth 361 and the positioning groove 311 reduces wear and tear, improving the service life of the device. Since the reset operation relies on mechanical structure rather than electronic control, the design maintains high reliability in various environmental conditions. The design of the positioning teeth 361, the positioning groove 311, and the reset part 362 is relatively simple, easy to check and replace, reducing the complexity and cost of maintenance. At the same time, this design makes the reset mechanism more compact, suitable for integration in devices with limited space, without affecting the layout of other components.
[0085] Figure 16 For Figure 1 Figure 2 shows a structural diagram of the tooth structure of the intrusion detection device.
[0086] As Figure 16 In some possible implementations, the tooth structure 40 includes a fixed shaft 41 and at least one tooth 42. The fixed shaft 41 is connected to the pressure rod 20. The tooth 42 is provided on the fixed shaft 41, and the tooth 42 corresponds to the counting disc 32 one-to-one. The tooth 42 is used to drive the corresponding counting disc 32 under the action of the pressure rod 20.
[0087] Specifically, when the tooth 42 moves under the action of the pressure rod 20, it abuts against the carryover tooth 321 or the driving tooth 322, thereby pressing the carryover tooth 321 or the driving tooth 322 to make the corresponding counting disc 32 rotate.
[0088] The tooth 42 corresponds to the counting disc 32 one-to-one, ensuring that the action of each tooth can accurately drive the corresponding counting disc 32, improving the accuracy of counting and ensuring that each opening of the case cover can be correctly recorded. The fixed shaft 41 connects the tooth 42 to the pressure rod 20, so that the tooth 42 can move synchronously when the pressure rod 20 acts, ensuring that the tooth contacts the counting disc 32 at the right time, improving the response speed and reliability of the device. Due to the direct correspondence between the tooth 42 and the counting disc 32, the counting error caused by misoperation is reduced, and the reliability of the overall system is improved. By mounting the tooth 42 on the fixed shaft 41, the entire structure is more compact, suitable for integration in devices with limited space, without affecting the layout of other components.
[0089] The design of the ratchet structure 40 is relatively simple, easy to manufacture and maintain. The combination of the fixed shaft 41 and the ratchet 42 does not require complex control mechanisms, reducing manufacturing and maintenance costs. The ratchet structure 40 can be adjusted and expanded as needed to adapt to different counting requirements and application scenarios, providing flexible design options. The mechanical ratchet structure 40 does not require power driving, making it suitable for use in power-off environments. The mechanical ratchet structure 40 generally has high durability and can maintain stable performance over a long period of use, reducing maintenance requirements.
[0090] Figure 17 For Figure 1 The structure diagram of the intrusion detection device without the protective cover is shown. Figure 18 For Figure 1 The structure diagram of the intrusion detection device without the protective cover is shown.
[0091] As Figure 17 and 18 In some possible implementations, the ratchet structure 40 includes three ratchets 42. The three ratchets 42 are respectively a first ratchet 421, a second ratchet 422, and a third ratchet 423. The first ratchet 421 corresponds to the first counting disc 33 and is used to ratchet the first counting disc 33 to rotate. The second ratchet 422 is smaller than the first ratchet 421 and corresponds to the second counting disc 34, which can ratchet the second counting disc 34 to rotate when the first counting disc 33 is incremented. The third ratchet 423 is smaller than the second ratchet 422 and corresponds to the third counting disc 35, which can ratchet the third counting disc 35 to rotate when the second counting disc 34 is incremented. The three ratchets 42 cooperate with each other to ratchet the first counting disc 33, the second counting disc 34, and the third counting disc 35 on the counting structure 30, realizing the opening box record.
[0092] In some possible implementations, the ratchet structure 40 further includes a connecting portion 43. The abutting portion 23 is further provided with a connecting hole 231. The connecting portion 43 is connected to the connecting hole 231 by a connecting member, so that the ratchet structure 40 is fixedly connected to the pressing rod 20.
[0093] In some possible implementations, the base 10 is further provided with a support seat 15. The rotating shaft 31 is rotatably arranged between the support seat 15 and the sleeve 12. The support seat 15 is provided with a guide groove 151. The fixed shaft 41 is movably arranged in the guide groove 151 away from the pressing rod 20.
[0094] The support seat 15 provides additional support for the rotating shaft 31, ensuring the stability of the rotating shaft 31 during rotation. This can reduce the shaking or deviation of the rotating shaft 31, improving the reliability of the entire device. Arranging the rotating shaft 31 between the support seat 15 and the sleeve 12 makes the entire structure more compact, which helps to save space and is suitable for integration in devices with limited space.
[0095] The guide slot 151 provides a clear path of motion for the fixed shaft 41, ensuring that the fixed shaft 41 maintains the correct orientation during movement. This precise guidance reduces the likelihood of misoperation, improving the accuracy of the ratchet structure 40. The guide slot 151 allows the fixed shaft 41 to move within a certain range, providing flexibility to adapt to different operational requirements and environmental changes, enhancing the adaptability of the device. By providing the fixed shaft 41 with a guide slot 151, friction and wear between the fixed shaft 41 and other components during movement are reduced, helping to extend the service life of the device.
[0096] The design of the support seat 15 and the guide slot 151 makes the installation of the rotating shaft 31 and the fixed shaft 41 more convenient, reducing the alignment and debugging time during installation. The combined design of the support seat 15 and the guide slot 151 reduces mutual interference and wear between components, improving the overall durability of the device.
[0097] In some possible implementations, the support seat 15 is provided with a rotating shaft hole 152. The rotating shaft 31 is rotatably arranged in the rotating shaft hole 152. The rotating shaft 31 is provided with a rotating groove 312 at one end facing the support seat 15. The rotating groove 312 is used to drive the rotating shaft 31 to rotate.
[0098] The rotating shaft hole 152 provides stable support for the rotating shaft 31, allowing the rotating shaft 31 to rotate smoothly and reducing the likelihood of shaking or deviation, thereby improving the reliability and accuracy of the entire device. By providing the rotating shaft hole 152 on the support seat 15, the rotation of the rotating shaft 31 is limited to a fixed path, reducing friction and wear with other components and extending the service life of the device.
[0099] The design of the rotating groove 312 provides a clear contact point for the driving force applied to the rotating shaft 31. This design ensures that the driving force can be effectively transmitted to the rotating shaft 31, achieving precise rotation control. The rotating groove 312 can be designed to accommodate different driving mechanisms (such as manual or automatic driving), providing flexible operation options.
[0100] The combination of the rotating shaft hole 152 and the rotating groove 312 provides a simple and effective mechanical driving method, reducing the need for complex electronic control systems and lowering manufacturing and maintenance costs. Integrating the rotating shaft hole 152 and the rotating groove 312 into the support seat 15 makes the entire structure more compact, saving space and suitable for integration in devices with limited space. Since the rotating shaft 31 is well supported in the rotating shaft hole 152 and the rotating groove 312 provides an effective driving mechanism, the durability and reliability of the entire system are improved.
[0101] In some possible implementations, the rotating groove 312 is a non-standard groove type that can only be matched by special tools to rotate the rotating shaft 31, reset the counting disc 32, and prevent unauthorized reset.
[0102] In some possible implementations, the sleeve 12 is provided with a support hole 122. The end of the rotating shaft 31 away from the support seat 15 is arranged in the support hole 122.
[0103] The support hole 122 provides stable support for the rotating shaft 31, allowing the rotating shaft 31 to rotate smoothly and reducing shaking or deviation of the rotating shaft 31, thereby improving the reliability and accuracy of the entire device. By arranging the rotating shaft hole 152 on the support seat 15 and the support hole 122 on the sleeve 12, the rotation of the rotating shaft 31 is limited to a fixed path, reducing friction and wear with other components, thereby prolonging the service life of the device.
[0104] In some possible implementations, the support seat 15 is provided with a locking hole 153. The locking hole 153 is used to fix and lock the support seat 15 to the base 10.
[0105] In some possible implementations, the intrusion detection device 100 further comprises a protective cover 50. The protective cover is arranged on the base 10 and covers the counting structure 30 and the ratchet structure 40. The protective cover 50 is provided with an abutting hole 51. The end of the pressing rod 20 away from the base 10 penetrates the abutting hole 51 to abut against the box cover.
[0106] The protective cover 50 provides a physical barrier for the internal counting structure 30 and ratchet structure 40, preventing the intrusion of dust, moisture and other external contaminants. This protection prolongs the service life of the device and improves its reliability. The protective cover 50 can also prevent external physical impact from damaging internal components, especially during equipment installation and transportation. This design reduces the risk of accidental damage. By covering the key components, the protective cover 50 can prevent unauthorized personnel from directly accessing and tampering with the internal structure, improving the security of the device. The design of the protective cover 50 makes the entire device more compact and integrated, facilitating installation and use in limited space.
[0107] The design of the abutting hole 51 allows the pressing rod 20 to penetrate and abut against the box cover. This design ensures that the device can work normally when the box cover is detected to be opened, without affecting the overall protection function of the protective cover 50.
[0108] In some possible implementations, the protective cover 50 is provided with an observation window 52 opposite the counting structure 30 to facilitate observation of the counting of the counting structure 30.
[0109] The observation window 52 allows the user to directly view the counting results of the counting structure 30 without the need to disassemble the protective cover 50. The design of the observation window 52 enables the user to view the count without opening the protective cover 50, thereby reducing interference with the internal structure and lowering the risk of misoperation and damage. This design improves user convenience, allowing quick access to counting information. Through the observation window 52, the user can monitor the status and counting changes of the counting structure 30 at any time, which is particularly important for application scenarios that require frequent checks, ensuring the normal operation of the device. Since the count can be read without disassembling the protective cover 50, the opportunity to expose the internal structure is reduced, improving the security of the device and preventing unauthorized access. The protective cover 50, while providing an observation function, still protects the internal structure from the external environment, extending the service life of the device.
[0110] In some possible implementations, the base 10 is also provided with a fixing hole 16 for fixing and locking the base 10 in the case, thereby fixing the entire intrusion detection device 100 in the server.
[0111] During installation, the reset spring 13 and the pressure rod 20 are sequentially placed in the pressure rod cavity 121 of the sleeve 12, and are fixed with the fixed cover 14. After assembly is completed, as shown in Figure 6 .
[0112] The first counting disc 33, the second counting disc 34, the third counting disc 35, and the corresponding reset member 36 are sequentially installed on the rotating shaft 31, and the rotating shaft 31 is fixed on the rotating shaft hole 152 and the support hole 122. The support seat 15 is fixed on the base 10 through the locking hole 153, and the ratchet structure 40 is installed on the pressure rod 20 through the connecting part 43 and the connecting hole 231. After assembly is completed, as shown in Figure 17 and Figure 18 .
[0113] Finally, the protective cover 50 is installed on the base 10, so that the abutting part 23 passes through the abutting hole 51, and the assembly of the intrusion detection device 100 is completed.
[0114] During use, when the case cover is closed, the pressure rod 20 is subjected to the downward force of the case cover, the first ratchet 421 drives the driving teeth 322 of the first counting disc 33 to rotate one tooth downward, and at the same time, the reset spring 13 is compressed to store energy. The triggering part 21 is in contact with the contact 11 to conduct electricity, providing an electrical signal to the BMC for collection and recording. Further, when the driving teeth 322 rotate to the carry-over teeth 321, i.e., after the ratchet 9 times, the second ratchet 422 can drive the driving teeth 322 of the second counting disc 34 to rotate one tooth, and so on, to drive the driving teeth 322 of the third counting disc 35, thereby realizing three-level decimal carry-over counting. Under normal circumstances, the number of times is consistent with the number of times of the contact 11 being turned on.
[0115] The counting disc 32 is reset, when it is needed to reset in a special scene (such as factory shipment / maintenance), a special tool is needed to rotate the rotating groove 312 to drive the three reset members 36 to rotate at the same time, so as to make the three reset teeth 324 in the same position, and realize the reset of the three counting discs 32 of the counting structure 30 in the same value.
[0116] When the counting value of the counting structure 30 is consistent with the BMC record value, it indicates that there is no illegal opening operation; when the counting value of the counting structure 30 is greater than the BMC record value, it indicates that the cover is opened, and the difference between the values is the number of times of opening the cover; when the counting value of the counting structure 30 is less than the BMC record value, it indicates that the number of times of opening the cover has exceeded 999 times; and when the counting value of the counting structure 30 is 0, it indicates that the factory reset or maintenance reset is performed.
[0117] The intrusion detection device 100 provided by the embodiment of the present application comprises a base 10, a pressing rod 20, a counting structure 30 and a tooth shifting structure 40. The base 10 is arranged in a case, and the base 10 is provided with a contact 11 electrically connected with the case. The pressing rod 20 is movably arranged on the base 10 and abuts against a cover of the case to trigger the contact 11. The counting structure 30 is rotatably arranged on the base 10, and the tooth shifting structure 40 is arranged on the pressing rod 20 to shift the counting structure 30 to count under the driving of the pressing rod 20.
[0118] By abutting the pressing rod 20 against the cover and triggering the contact 11 electrically connected with the case, the opening self-checking of the server in the power-on state can be realized. In addition, since the device is provided with the rotating counting structure 30 and the tooth shifting structure 40 arranged on the pressing rod 20, the pressing rod 20 can drive the tooth shifting structure 40 to shift and count the counting structure 30 after each time the cover is opened, so that the physical counting of the opening of the server cover is realized. Through the combination of the physical counting and the server power-on self-checking counting, not only the problem of recording the opening of the case and the problem of recording the number of times of opening can be solved in the power-off state, but also the number of times of opening the case can be more accurately determined through the double-checking mechanism of the physical counting and the server power-on self-checking counting, especially in the offline state, the potential physical intrusion behavior can be effectively identified through the overlapping checking, and the security protection capability of the server is improved.
[0119] In addition, the embodiment of the present application also provides a server comprising a case and an intrusion detection device 100, and the intrusion detection device 100 is arranged in the case.
[0120] Since the server in the embodiment comprises the intrusion detection device 100 described in any of the above embodiments, the server comprises the structure and advantages of the intrusion detection device 100, and the embodiment will not be described here.
[0121] The above describes in detail the intrusion detection device and the server provided by the application. The principles and implementation manners of the application are described by using specific examples in the text, and the above description of the examples is only used to help understand the method of the application and the core idea thereof. It should be pointed out that, for those skilled in the art, some improvements and modifications can be made to the application without departing from the principles of the application, and these improvements and modifications also fall within the protection scope of the claims of the application.
