Description

Technical Field

[0001] This application relates to the field of server technology, and more specifically, to a lock and electronic device. Background Technology

[0002] As a key component of high-performance servers, graphics cards are responsible for processing graphics and textures. Any program that wants to display graphics needs to rely on the graphics card for processing. Graphics cards embody a significant amount of core national technology and contain important information such as trade secrets. With the continuous development of the information industry, the performance requirements of servers for graphics cards are becoming increasingly demanding. Traditional encrypted servers are typically equipped with sophisticated mechanical locks designed to control the opening and closing of the server chassis with specific keys, thereby preventing unauthorized personnel from accessing the server's internal hardware and data. In addition, software encryption strategies are also widely used to enhance the security of data transmission and storage. This combination of strategies significantly improves the server's security level, meeting the basic information security needs of most enterprises and organizations.

[0003] However, while traditional mechanical locks and software encryption can prevent unauthorized external intrusion to some extent, a significant security blind spot exists during normal server maintenance or upgrades. In research institutions and laboratories, servers store research data and technological achievements. If this information is leaked, it could cause irreversible damage to the research process. When an unauthorized user uses a key to open the server's physical lock, because the lock design does not include verifiable evidence of unauthorized use, it is almost impossible to determine from the lock itself whether it has been illegally opened a second time once the server is shut down again. This means that even if the server is opened with a legitimate key and undergoes maintenance, it cannot be ruled out that the information inside the server may have been illegally accessed or stolen during or after the maintenance period. Summary of the Invention

[0004] This application provides a lock and electronic device to solve the problem that conventional mechanical locks on servers in the prior art are difficult to effectively determine whether the server has been illegally opened.

[0005] This application provides a lock mounted on a chassis, which includes a housing, a rear window structure, and a cover. The cover and the rear window structure are detachably mounted via a locking connector. The lock includes a lock base structure and a lock cylinder structure. The lock base structure is detachably mounted on the rear window structure to cover the locking connector. The lock cylinder structure has a breaking part. The lock has a locked state and an unlocked state. When the lock is in the locked state, the lock base structure and the lock cylinder structure are locked together, and the breaking part is exposed to the outside. When the lock is in the unlocked state, the breaking part breaks, thereby separating the lock cylinder structure from the lock base structure, and thus separating the lock base structure from the rear window structure.

[0006] Furthermore, the lock seat structure includes a lock seat body and a lock seat connector. The lock seat body is provided with a lock seat connection hole, and the lock seat connector can be inserted into the lock seat connection hole. The rear window structure is provided with a rear window connection hole, and the rear window connection hole is correspondingly provided with the lock seat connection hole, so as to fix the lock seat structure to the rear window structure through the lock seat connector.

[0007] Furthermore, the lock seat structure also includes a lock seat positioning part, and a rear window positioning part is provided on the rear window structure. The lock seat positioning part and the rear window positioning part are correspondingly provided so that after the lock seat positioning part and the rear window positioning part are positioned and cooperated, the lock seat structure is fixed on the rear window structure by the lock seat connector.

[0008] Furthermore, the lock seat positioning part is a positioning post, or a positioning protrusion, or a positioning groove, or a positioning hole; and / or, the rear window positioning part is a positioning hole, or a positioning groove, or a positioning protrusion, or a positioning post.

[0009] Furthermore, the lock seat structure is provided with a first mating part and a second mating part, and the lock cylinder structure is provided with a first locking part and a second locking part. When the lock is in the locked state, the first mating part and the first locking part lock together, and the second mating part and the second locking part lock together to complete the locking of the lock seat structure and the lock cylinder structure.

[0010] Furthermore, the lock seat structure also includes a first mating part and a second mating part, which are respectively disposed opposite to each other on both sides of the lock seat body. The first mating part is disposed on the first mating part, and the second mating part is disposed on the second mating part.

[0011] Furthermore, the first mating part includes a first sliding position and a first limiting position disposed on the first mating member. The first sliding position and the first limiting position are arranged along the direction of the first mating member gradually approaching the lock seat body, so that the first locking part enters from the first sliding position into the first limiting position and cooperates with the second mating part to limit the lock cylinder structure within the locking space; wherein, the locking space is formed by the lock seat body, the first mating member and the second mating member.

[0012] Furthermore, the second mating part is a first snap-fit ​​position provided on the second mating member. The first snap-fit ​​position is provided to engage with the second locking part so that when the first locking part enters into the first limiting position, the second locking part engages with the first snap-fit ​​position.

[0013] Furthermore, the first locking part includes a first sliding part, a second sliding part, and a limiting part. The first sliding part is disposed on the second sliding part, and the second sliding part is disposed on the limiting part. The cross-sectional area of ​​the limiting part is larger than the cross-sectional area of ​​the first sliding part, and the cross-sectional area of ​​the first sliding part is larger than the cross-sectional area of ​​the limiting part. The first sliding part slides in cooperation with the first sliding position, and the second sliding part slides in cooperation with the first limiting position. When the first sliding part enters the first limiting position from the first sliding position, the lock cylinder structure moves towards the direction of the second cooperation part, so that the second sliding part enters the first limiting position. The limiting part abuts against the side of the first cooperation member away from the second cooperation member.

[0014] Furthermore, the first locking part also includes a transition part disposed between the first sliding part and the second sliding part, and the cross-sectional area of ​​the transition part gradually increases along the arrangement direction from the first sliding part to the second sliding part.

[0015] Furthermore, at least a portion of the second locking portion is deformably configured such that, during the process of the at least portion of the second locking portion entering the first engaging position, the at least portion of the second locking portion deforms, and when the first locking portion enters the first limiting position, the at least portion of the second locking portion extends from the first engaging position to the outside of the second mating member, and the at least portion of the second locking portion returns to its original state and engages with the second mating member in a limiting engagement.

[0016] Furthermore, the lock cylinder structure also includes an information panel, with a first locking part and a second locking part respectively disposed on opposite sides of the information panel; wherein, a destructive part is disposed between the second locking part and the information panel.

[0017] Furthermore, the second locking part includes a support part and a pawl. The pawl is deformably configured and has a limiting surface, so that when the pawl extends to the outside of the second mating member, the limiting surface contacts the second mating member to limit the pawl.

[0018] Furthermore, when there are multiple claws, the multiple claws are all arranged on one side of the support and distributed circumferentially around the outer wall of the support. Each claw can be selectively deformed in the direction of getting closer to each other so that the second locking part passes through the first locking position.

[0019] Furthermore, the chuck includes a first portion and a second portion. The first portion is disposed on one side of the support portion, and the second portion is disposed on the side of the first portion away from the support portion. The second portion has a limiting surface, and the limiting surfaces together form a limiting end face that contacts the second mating part.

[0020] Furthermore, the second part also has a guide surface, which is provided corresponding to the limiting surface. The guide surface is inclined relative to the limiting surface, and all the guide surfaces together form a guide end face, so as to guide the second locking part through the guide end face during the process of the second locking part entering the first locking position.

[0021] Furthermore, the angle between the guide surface and its corresponding limiting surface is an acute angle.

[0022] Furthermore, the claw also includes a third portion, which is located on the side of the second portion relatively close to the support portion, and the end face of the third portion is a limiting surface; and / or, multiple claws are spaced apart.

[0023] Furthermore, a first mounting position is provided on the rear window structure, and a second mounting position is provided on the cover. The first mounting position and the second mounting position are provided in a one-to-one correspondence. The chassis also includes a locking connector that can be inserted into the first mounting position, so as to fix the chassis to the rear window structure through the locking connector.

[0024] According to another aspect of this application, this application also provides an electronic device, including a server chassis and a lock. The server chassis includes a chassis body, a cover plate, and a rear window structure. The cover plate and the rear window structure are detachably connected by a locking connector. The lock includes a lock seat structure and a lock cylinder structure. The lock seat structure is detachably mounted on the rear window structure to cover the locking connector. The lock cylinder structure has a breaking part. The lock has a locked state and an unlocked state. When the lock is in the locked state, the lock seat structure and the lock cylinder structure are locked together, and the breaking part is exposed to the outside. When the lock is in the unlocked state, the breaking part breaks, thereby separating the lock cylinder structure from the lock seat structure, and thus separating the lock seat structure from the rear window structure.

[0025] This application achieves a secure connection between the chassis cover and the rear window structure through the locking fit between the lock seat structure and the lock cylinder structure, effectively preventing unauthorized disassembly. The precise fit between the lock seat structure and the lock cylinder structure, as well as the obstruction of the locking connector, ensures a secure locked state between the chassis cover and the rear window structure, preventing unauthorized access to the internal hardware and protecting the information security of the core equipment.

[0026] The exposed design of the breaching part allows for intuitive identification of the lock's status, enhancing the warning of potential threats. When locked, the breaching part is exposed to the outside, providing staff with intuitive identification of the lock's status. Any attempt to illegally open the lock will directly damage the breaching part, leaving obvious traces of the operation, which facilitates subsequent security audits and accountability.

[0027] The mechanism of breaking the breakage part enables forced separation after the lock is unlocked, ensuring the irreversibility of the lock. In the unlocked state, the breakage part breaks, which ensures the complete separation of the lock cylinder structure and the lock seat structure, making the lock unusable. Any unlocking operation will result in physical damage to the lock. This irreversible unlocking mechanism improves the recordability of maintenance operations, making it easier to track the maintenance history of the server chassis, thereby enhancing the security and compliance of equipment maintenance.

[0041] 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.

[0042] As mentioned in the background section, graphics cards, as key components of high-performance servers, are responsible for processing graphics textures. Any program that wants to display graphics needs to rely on the graphics card for processing. Graphics cards embody a significant amount of core national technologies and important information such as trade secrets. With the continuous development of the information industry, the performance requirements of servers for graphics cards are becoming increasingly demanding. Traditional encrypted servers are typically equipped with sophisticated mechanical locks designed to control the opening and closing of the server chassis with specific keys, thereby preventing unauthorized personnel from accessing the server's internal hardware and data. In addition, software encryption strategies are also widely used to enhance the security of data transmission and storage. This combination of strategies significantly improves the security level of servers, meeting the basic information security needs of most enterprises and organizations.

[0043] However, while traditional mechanical locks and software encryption can prevent unauthorized external intrusion to some extent, a significant security blind spot exists during normal server maintenance or upgrades. In research institutions and laboratories, servers store research data and technological achievements. If this information is leaked, it could cause irreversible damage to the research process. When an unauthorized user uses a key to open the server's physical lock, because the lock design does not include verifiable evidence of unauthorized use, it is almost impossible to determine from the lock itself whether it has been illegally opened a second time once the server is shut down again. This means that even if the server is opened with a legitimate key and undergoes maintenance, it cannot be ruled out that the information inside the server may have been illegally accessed or stolen during or after the maintenance period.

[0044] Therefore, the main objective of this application is to provide a lock and electronic device to solve the problem that conventional mechanical locks on servers in the prior art are difficult to effectively determine whether a server has been illegally opened.

[0045] Example 1

[0046] like Figures 1 to 8 As shown, this application embodiment first provides a lock, which is installed on a chassis. The chassis includes a body 1, a rear window structure 2, and a cover 3. The cover 3 and the rear window structure 2 are detachably installed through a locking connector 4. A first mounting position is provided on the rear window structure 2, and a second mounting position is provided on the cover 3. The first mounting position and the second mounting position are provided in a one-to-one correspondence. The chassis also includes a locking connector 4 that can be inserted into the first mounting position so as to fix the body 1 to the rear window structure 2 through the locking connector 4.

[0047] Optionally, the first mounting position and the second mounting position are threaded holes.

[0048] Optionally, the locking connector 4 is a locking bolt.

[0049] Furthermore, the lock includes a lock seat structure 5 and a lock cylinder structure 6. The lock seat structure 5 is detachably mounted on the rear window structure 2 to cover the locking connector 4. The lock cylinder structure 6 has a breaking part 61. The lock has a locked state and an unlocked state. When the lock is in the locked state, the lock seat structure 5 and the lock cylinder structure 6 are locked together, and the breaking part 61 is exposed to the outside. When the lock is in the unlocked state, the breaking part 61 breaks, so that the lock cylinder structure 6 is separated from the lock seat structure 5, and so that the lock seat structure 5 is separated from the rear window structure 2. After the lock seat structure 5 and the rear window structure 2 are separated, the box cover 3 and the box body 1 can be separated by disassembling the locking connector 4.

[0050] In a further embodiment of this application, the lock adopts a design including a lock base structure 5 and a lock cylinder structure 6, which significantly improves the security and management efficiency of the server chassis. The lock base structure 5 is detachably mounted on the rear window structure 2, effectively shielding and protecting the locking connector 4; the lock cylinder structure 6 has a key destructive part 61 inside. When the lock is in the normal locked state, the destructive part 61 is exposed to the outside, but once an unauthorized unlocking attempt occurs, the destructive part 61 will break. This one-time destruction mechanism ensures irreversible unlocking of the lock, providing an insurmountable physical barrier for the security of the server's internal data and hardware.

[0051] Furthermore, such as Figure 4 As shown, the lock seat structure 5 includes a lock seat body 51 and a lock seat connector. A lock seat connection hole 52 is provided on the lock seat body 51, and the lock seat connector can be inserted into the lock seat connection hole 52. A rear window connection hole 21 is provided on the rear window structure 2, and the rear window connection hole 21 is correspondingly provided with the lock seat connection hole 52, so that the lock seat structure 5 can be fixed on the rear window structure 2 through the lock seat connector.

[0052] Optionally, the lock seat connector is a locking bolt.

[0053] Optionally, the lock seat connection hole 52 is a threaded hole.

[0054] Optionally, the rear window connection hole 21 is a threaded hole.

[0055] The corresponding design of the lock seat connection hole 52 and the rear window connection hole 21 allows the lock seat structure 5 to form a stable connection with the rear window structure 2. Even during server operation, vibrations can effectively prevent the lock seat from loosening, ensuring the safety of internal components. The interlocking design of the lock seat connector simplifies the installation and disassembly steps of the lock seat structure 5. No complex tools or professional skills are required for quick assembly and separation of the lock seat structure 5 and the rear window structure 2. By designing the lock seat structure 5 as an independent module and connecting it to the rear window structure 2 through the rear window connection hole 21, standardization and versatility of the lock seat structure 5 are achieved. This allows the lock to be used in server chassis of different models and sizes, reducing the customization cost of accessories and improving supply chain flexibility.

[0056] Furthermore, the lock seat structure 5 also includes a lock seat positioning part 53, and a rear window positioning part 22 is provided on the rear window structure 2. The lock seat positioning part 53 and the rear window positioning part 22 are correspondingly provided so that after the lock seat positioning part 53 and the rear window positioning part 22 are positioned and cooperated, the lock seat structure 5 is fixed on the rear window structure 2 by the lock seat connector.

[0057] The precise matching between the lock seat positioning part 53 and the rear window positioning part 22 provides a preliminary positioning reference for the installation of the lock seat structure 5 on the rear window structure 2, making the subsequent fixing operation of the lock seat connector more accurate and error-free, greatly reducing connection problems caused by inaccurate positioning, and ensuring a stable connection between the lock seat structure 5 and the rear window structure 2.

[0058] The presence of the lock seat positioning part 53 simplifies the installation process of the lock seat structure 5. Maintenance personnel can quickly align and fix the lock seat structure 5 with the rear window structure 2 without additional adjustments, effectively improving the efficiency and accuracy of installation.

[0059] Through the dual functions of the rear window positioning part 22, the lock seat positioning part 53, and the lock seat connector, not only is the positional consistency of the lock seat structure 5 on the rear window structure 2 ensured, but the durability of the connection is also enhanced. Even if the server is subjected to vibration during long-term operation or transportation, it can maintain a good sealing effect and structural integrity, reducing safety hazards caused by external factors.

[0060] Optionally, the locking seat positioning part 53 can be any one of a positioning post, a positioning protrusion, a positioning groove, or a positioning hole.

[0061] Optionally, the rear window positioning part 22 may be a positioning hole, a positioning groove, a positioning protrusion, or a positioning post.

[0062] In some embodiments of this application, when the lock seat positioning part 53 is a positioning post, the rear window positioning part is a positioning hole used in conjunction with the positioning post.

[0063] In some embodiments of this application, when the lock seat positioning part 53 is a positioning protrusion, the rear window positioning part is a positioning groove that cooperates with the positioning protrusion.

[0064] In some embodiments of this application, when the lock seat positioning part 53 is a positioning groove, the rear window positioning part is a positioning protrusion that cooperates with the positioning groove.

[0065] In some embodiments of this application, when the lock seat positioning part 53 is a positioning hole, the rear window positioning part is a positioning post used in conjunction with the positioning hole.

[0066] Furthermore, the lock base structure 5 is provided with a first mating part 54 and a second mating part 55, and the lock cylinder structure 6 is provided with a first locking part 62 and a second locking part 63. When the lock is in the locked state, the first mating part 54 locks with the first locking part 62, and the second mating part 55 locks with the second locking part 63, so as to complete the locking of the lock base structure 5 and the lock cylinder structure 6.

[0067] The double locking of the first mating part 54 and the first locking part 62, as well as the second mating part 55 and the second locking part 63, forms a robust locking system, which significantly improves the security performance of the lock. The double locking design not only enhances the stability of the lock under normal working conditions, but also improves the lock's resistance to external impacts, ensuring the safe operation of the server in various complex environments.

[0068] Furthermore, the lock seat structure 5 also includes a first mating part 56 and a second mating part 57, which are respectively disposed opposite to each other on both sides of the lock seat body 51. The first mating part 54 is disposed on the first mating part 56, and the second mating part 55 is disposed on the second mating part 57.

[0069] Specifically, the first mating part 56 and the second mating part 57 are arranged parallel to each other on both sides of the lock seat body 51, and the extension direction of the first mating part 56 and the second mating part 57 is perpendicular to the upper surface of the lock seat body 51.

[0070] By arranging the first mating part 56 and the second mating part 57 perpendicular to the upper surface of the lock seat body 51, the rigidity of the lock seat structure 5 in the longitudinal direction and the stability in the lateral direction are enhanced, enabling it to effectively resist external lateral impacts and pressures and ensure the safety performance of the lock in complex environments.

[0071] The first mating part 54 and the second mating part 55 are located on the first mating part 56 and the second mating part 57, respectively. This separate layout is conducive to improving the accuracy of the locking fit and ensuring that a stable and reliable lock can be formed between the lock seat and the lock cylinder structure 6, thereby effectively preventing illegal opening.

[0072] The parallel arrangement of the first mating part 56 and the second mating part 57 simplifies the assembly process of the lock, making the combination and separation of the lock seat structure 5 and the lock cylinder structure 6 more intuitive and convenient, and improving the efficiency of server maintenance.

[0073] The positional design of the first mating component 56 and the second mating component 57 optimizes the overall layout of the lock seat structure 5, which not only ensures a stable connection between the lock seat structure and the rear window structure 2, but also avoids occupying the internal space of the server, which is conducive to improving the heat dissipation performance of the server and the rationality of the layout of internal components.

[0074] like Figure 4As shown, the first mating part 54 further includes a first sliding position 541 and a first limiting position 542 disposed on the first mating member 56. The first sliding position 541 is a strip groove formed on the first mating member 56, and the first limiting position 542 is a circular hole formed on the first mating member 56. The first sliding position 541 and the first limiting position 542 are connected. The first sliding position 541 and the first limiting position 542 are arranged along the direction of the first mating member 56 gradually approaching the lock seat body 51. With this arrangement, the first locking part 62 can enter from the first sliding position 541 into the first limiting position 542 and cooperate with the second mating part 55 to limit the lock cylinder structure 6 within the locking space. The locking space is formed by the lock seat body 51, the first mating member 56 and the second mating member 57.

[0075] The first locking part 62 enters the first limiting part 542 through the guide of the first sliding part 541, which not only ensures the smooth locking process, but also provides a stable limit after locking, improving the adaptability and stability of the lock under different usage conditions. The circular hole design of the first limiting part 542, combined with the size of the lock cylinder structure 6, forms an effective physical restriction. Even if subjected to external impact, the lock cylinder structure 6 is not easy to dislodge, ensuring the robust protection of the server in terms of physical security.

[0076] The first sliding position 541 and the first limiting position 542 are arranged along the direction of the first mating member 56 gradually approaching the lock seat body 51, which not only ensures the effectiveness of the locking mechanism, but also optimizes the spatial layout of the lock seat structure 5 and avoids additional occupation of the internal space of the server.

[0077] like Figure 4 As shown, the second mating part 55 is a first snap-fit ​​position provided on the second mating member 57. The first snap-fit ​​position is a through hole that passes through the second mating member 57. The first snap-fit ​​position is provided to snap-fit ​​with the second locking part 63 so that when the first locking part 62 enters into the first limiting position 542, the second locking part 63 snaps-fit with the first snap-fit ​​position.

[0078] The cooperation between the first locking part 62 and the first limiting position 542, along with the engagement between the second locking part 63 and the first locking position, ensures the precise engagement of the lock in the locked state, reducing security risks caused by loosening. The engagement between the second locking part 63 and the first locking position provides additional stability to the lock cylinder structure 6, ensuring that the lock remains firmly locked even when the server is subjected to vibration or impact, further enhancing the security level of physical protection.

[0079] Furthermore, such as Figure 3As shown, the first locking part 62 includes a first sliding part 621, a second sliding part 624, and a limiting part 623. The first sliding part 621 is disposed on the second sliding part 624, and the second sliding part 624 is disposed on the limiting part 623. The cross-sectional area of ​​the limiting part 623 is larger than that of the first sliding part 621, and the cross-sectional area of ​​the first sliding part 621 is larger than that of the limiting part 623. The first sliding part 621 is slidably engaged with the first sliding position 541, and the second sliding part 624 is slidably engaged with the first limiting position 542. When the first sliding part 621 enters the first limiting position 542 from the first sliding position 541, the lock cylinder structure 6 is moved towards the second mating part 55, so that the second sliding part 624 enters the first limiting position 542. The limiting part 623 abuts against the side of the first mating member 56 away from the second mating member 57.

[0080] During the locking process, the multi-stage mechanism design of the first locking part 62 makes the locking operation present a progressive cooperation process. First, the first sliding part 621 smoothly transitions in the first sliding position 541. Then, the second sliding part 624 is precisely embedded in the first limiting position 542. Finally, the contact between the limiting part 623 and the first mating part 56 forms the final safety barrier, ensuring the stable locking state of the lock.

[0081] The contact and abutment between the limiting part 623 and the first mating part 56 not only increases the structural strength of the lock, but also effectively restricts the lateral displacement of the lock cylinder structure 6, greatly enhancing the anti-pry function of the lock. Even under strong attack, the lock cylinder structure 6 is difficult to be forcibly pulled out of the lock seat structure 5, significantly improving the physical security performance of the server chassis.

[0082] The multi-stage locking mechanism design makes the lock assembly more intuitive. The operator only needs to push the lock cylinder structure 6 along the locking path to complete the engagement with the first sliding position 541 and the first limiting position 542 in sequence, which simplifies the complexity of lock assembly and improves the user experience.

[0083] The large cross-sectional area of ​​the limiting part 623 provides the necessary structural strength, while the small cross-sectional areas of the first sliding part 621 and the second sliding part 624 help to reduce the overall volume of the lock cylinder structure 6.

[0084] Optionally, the first sliding part 621 is cylindrical, the second sliding part 624 is cylindrical, and the limiting part 623 is cylindrical.

[0085] Furthermore, the first locking part 62 also includes a transition part 622 disposed between the first sliding part 621 and the second sliding part 624, and the cross-sectional area of ​​the transition part 622 gradually increases along the arrangement direction from the first sliding part 621 to the second sliding part 624.

[0086] The gradient cross-section design of the transition section 622 makes the operation of the lock cylinder structure 6 smoother and more natural as it slides from the first sliding position 541 to the first limiting position 542. The locking action no longer requires sudden force adjustments, reducing operational uncertainty and potential mechanical wear, and extending the lifespan of the lock.

[0087] When the first sliding part 621 smoothly passes through the first sliding position 541 and transitions to the first limiting position 542, the gradually increasing cross-sectional area of ​​the transition part 622 effectively prevents the lock cylinder structure 6 from shaking or accidentally dislodging in the locked state, enhancing the stability of the lock and thus improving the reliability of the physical security protection of the server.

[0088] After the first sliding part 621 and the second sliding part 624 both enter the first limiting position 542, the limiting part 623 abuts against the side of the first mating part 56 away from the second mating part 57. At this time, the gradual design of the transition part 622 ensures a stable fit between the lock cylinder structure 6 and the lock seat structure 5. Even under the vibration generated by the operation of the server or external impact, the lock can remain locked and effectively prevent illegal opening.

[0089] Furthermore, such as Figure 3 As shown, at least a portion of the second locking part 63 is deformably configured such that, during the process of the at least portion of the second locking part 63 entering the first engaging position, the at least portion of the second locking part 63 deforms under the action of the first engaging position, and when the first locking part 62 enters into the first limiting position 542, the at least portion of the second locking part 63 extends from the first engaging position to the outside of the second mating member 57, and after losing the action of the first engaging position, the at least portion of the second locking part 63 returns to its original state and engages with the second mating member 57.

[0090] During the assembly of the lock cylinder structure 6, the deformable feature of the second locking part 63 allows the lock cylinder structure 6 to pass through the first locking position more easily. The appropriate deformation of the second locking part 63 when entering the first locking position avoids the assembly difficulties caused by rigid locking, improves the compatibility of the lock, and also speeds up the assembly process and simplifies the operation steps.

[0091] After the first locking part 62 successfully enters the first limiting position 542, the deformable part of the second locking part 63, after losing the constraint of the first latching position, automatically returns to its original shape and extends to the outside of the second mating part 57, forming a limiting engagement with it. This design ensures the stability of the lock cylinder structure 6 in the locked state, and can maintain the locked state even when faced with external impact, greatly improving the security level of the server.

[0092] Furthermore, the lock cylinder structure 6 also includes an information panel 64, with a first locking part 62 and a second locking part 63 respectively disposed on opposite sides of the information panel 64; wherein, a destructive part 61 is disposed between the second locking part 63 and the information panel 64.

[0093] Furthermore, the second locking part 63 includes a support part 631 and a claw 632. The claw 632 is deformably disposed and a limiting surface 633 is provided on the claw 632 so that when the claw 632 extends to the outside of the second mating member 57, the limiting surface 633 contacts the second mating member 57 to limit the claw 632.

[0094] Furthermore, when there are multiple claws 632, the multiple claws 632 are all arranged on one side of the support portion 631 and distributed circumferentially around the outer wall surface of the support portion 631. Each claw 632 can be selectively deformed in the direction of getting closer to each other, so that the second locking portion 63 passes through the first locking position.

[0095] Optionally, each of the claws 632 deforms and moves toward each other under the action of the first engagement hole.

[0096] The claw 632 is provided with a limiting surface 633. When the claw 632 extends outside the second mating part 57, the limiting surface contacts the second mating part 57 to form a stable limiting engagement. The design of multiple claws 632 allows the lock cylinder structure 6 to form more contact points with the lock seat structure 5 in the locked state, greatly enhancing the stability and security of locking and reducing the risk of unauthorized access or accidental unlocking.

[0097] When multiple pawls 632 need to pass through the first locking position, they can all deform towards each other. This feature simplifies the locking process of the lock. The operator does not need to apply force to each pawl 632 individually. By applying appropriate force to the support 631, all pawls 632 can deform synchronously and pass through the first locking position smoothly to complete the locking and improve the locking efficiency.

[0098] When there are multiple latches 632, they are evenly distributed around the circumference of the support 631. This layout optimizes the lock's structure, making it more compact and robust. Under the action of the first locking hole, all latches 632 deform synchronously towards each other, making the locking action more natural and smooth.

[0099] Furthermore, the claw 632 includes a first portion 6321 and a second portion 6322. The first portion 6321 is disposed on one side of the support portion 631, and the second portion 6322 is disposed on the side of the first portion 6321 away from the support portion 631. The second portion 6322 has a limiting surface 633, and the various limiting surfaces 633 together form a limiting end face that contacts the second mating member 57.

[0100] Furthermore, the second portion 6322 also has a guide surface 6323, which is correspondingly provided with the limiting surface 633. The guide surface 6323 is inclined relative to the limiting surface 633. Each guide surface 6323 is provided on the side of the second portion 6322 away from each other. Each guide surface 6323 together forms a guide end face. The guide end face is conical. The small diameter end of the guide end face is provided away from the breaking part 61, and the large diameter end of the guide end face is provided close to the breaking part 61, so that the guide end face can guide the second locking part 63 during the process of the second locking part 63 entering the first engaging position.

[0101] Furthermore, the angle between the guide surface 6323 and its corresponding limiting surface 633 is an acute angle.

[0102] Furthermore, such as Figure 3 As shown, the claw 632 also includes a third portion 6324, which is disposed on the side of the second portion 6322 that is relatively close to the support portion 631, and the end face of the third portion 6324 is a limiting surface 633.

[0103] Optionally, multiple claws 632 can be spaced apart.

[0104] The second part 6322 has an inclined guide surface 6323 and a limiting surface 633, which are arranged opposite to each other. The acute angle between the guide surface 6323 and the limiting surface 633 allows the claw 632 to be precisely guided by the guide surface during its entry into the first engagement position, reducing friction and resistance during assembly and ensuring a stable fit between the locking part and the engagement position. The limiting surface 633 contacts the second mating part 57 after the claw 632 is fully extended, forming a limiting end face that securely locks the lock cylinder structure 6, improving the security of the lock.

[0105] The guide end face is designed in a conical shape, with the small diameter end away from the breaking part 61 and the large diameter end close to the breaking part 61. This structure can prevent the lock seat structure 5 and the lock cylinder structure 6 from being easily separated after locking.

[0106] The addition of the third part 6324 further strengthens the structure of the pawl 632. Its limiting surface 633 increases the contact area with the second mating part 57, improving the overall strength of the lock and ensuring durability and stability during long-term use.

[0107] The spacing of multiple claws 632 optimizes the internal layout of the lock cylinder structure 6, avoids interference between the claws 632, and also reduces production costs.

[0108] During use, the box body 1 and the box cover 3 are first connected together by the locking connector 4. Then, the lock seat structure 5 is locked into the rear window connection hole 21 by the lock seat connector. Next, the first sliding part 621 is inserted into the first limiting position 542 through the first sliding position 541. Then, the lock cylinder structure 6 is pushed towards the side closer to the second mating part 57. Under the action of the thrust, the first sliding part 621 enters the locking space. At this time, the transition part 622 contacts the first limiting position 542 for transition. Continue to push the lock cylinder structure 6 towards the side closer to the second mating part 57. At this time, the second sliding part 624 enters the first limiting position 542 until the side of the limiting part 623 that is relatively close to the second sliding part 624 is relatively far away from the first mating part 56. One side of the mating part 57 is in contact with the other side; during the entire pushing process, the guide surface 6323 in the second locking part 63 is in contact with the inner wall surface of the second mating part 55. Under the action of the thrust, the second locking part 63 continues to move until the limiting end face formed by the limiting surfaces 633 of all the claws 632 is in contact with the side of the second mating part 57 away from the first mating part 56. At this time, the installation of the lock cylinder structure 6 and the lock seat structure 5 is completed. At this time, the breaking part 61 is exposed to the outside. If the box cover 3 and the box body 1 are to be opened, the breaking part 61 needs to be broken first, and then the lock cylinder structure 6 and the lock seat structure 5 need to be separated. Then the lock seat connector is opened. At this time, the locking connector 4 is exposed to the outside. In this case, the box cover 3 and the box body 1 can be separated simply by opening the locking connector.

[0109] Example 2

[0110] This application embodiment also provides an electronic device, including a server chassis and a lock. The server chassis includes a chassis body, a cover plate, and a rear window structure 2. The cover plate and the rear window structure 2 are detachably connected by a locking connector 4. The lock includes a lock seat structure 5 and a lock cylinder structure 6. The lock seat structure 5 is detachably connected to the rear window structure 2 to cover the locking connector 4. The lock cylinder structure 6 has a breaking part 61. The lock has a locked state and an unlocked state. When the lock is in the locked state, the lock seat structure 5 and the lock cylinder structure 6 are locked together, and the breaking part 61 is exposed to the outside. When the lock is in the unlocked state, the breaking part 61 breaks, so that the lock cylinder structure 6 is separated from the lock seat structure 5, and so that the lock seat structure 5 is separated from the rear window structure 2.

[0111] The locking fit between the lock seat structure 5 and the lock cylinder structure 6 effectively shields the locking connector 4, preventing outsiders from easily accessing it. This significantly improves the physical security of the equipment and prevents unauthorized disassembly and information leakage.

[0112] In the lock design, the destructive part 61 is exposed when locked, which is a clear warning sign that anyone attempting to illegally dismantle the lock will face damage to the lock, further enhancing the deterrent effect against potential threats.

[0113] The technical solution of this application is applied to specific fields such as scientific research institutions or laboratories, to prevent the illegal use of the equipment while it is inside the chassis.

[0114] In this technical solution, each lock and each chassis are configured in a one-to-one correspondence. The information panel 64 on the lock is engraved with the model information of the chassis. When the lock and chassis are separated, the lock needs to be recycled. In this case, to prevent the separation between the chassis 1 and the cover 3, a contact sensor needs to be configured for each lock. A sensor receiving slot can be opened on the lock base structure 5, and the contact sensor is installed in the sensor receiving slot. The detection end of the contact sensor is set towards the lock cylinder structure 6, so that when the lock is in the locked state, the detection end of the contact sensor is in contact with the information panel 64 of the lock cylinder structure 6, and when the lock is in the unlocked state, the detection end of the contact sensor is in contact with the information panel. When the lock cylinder structure 6 and lock seat structure 5 separate, the contact sensor cannot detect the lock cylinder structure 6. In this case, the contact sensor will send a signal indicating that the lock has been damaged to the backend. The backend will then check the chassis model corresponding to the contact sensor and promptly communicate the information about the damaged lock on the chassis to the owner of the chassis. The contact sensor and the backend are connected by a signal. Through the above settings, when the lock cylinder structure 6 and lock seat structure 5 separate, the contact sensor will promptly send the signal to the backend for processing. At the same time, by directly detecting the physical contact state between the lock cylinder structure 6 and lock seat structure 5, the contact sensor can provide more accurate detection results and reduce false alarms or missed alarms.

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