Description

Technical Field

[0001] This invention relates to the field of security protection technology, and in particular to a security protection system and server. Background Technology

[0002] A server is a high-performance computing device used to store and manage computing resources, data, and applications, and to provide services to other devices or users, supporting the operation of critical infrastructure such as the Internet and cloud computing. Servers undertake critical tasks such as data storage, forwarding, and distribution, and are an indispensable and important component of the network. Most existing servers use mechanical locks to secure the server enclosure and lid, preventing the theft of the storage media containing confidential data and thus avoiding the risk of data leakage.

[0003] However, the mechanical locks used in these servers are easily opened by data thieves after repeated attempts, posing a high risk of data theft. Summary of the Invention

[0004] To address the aforementioned issues, the security protection system and server provided by this invention can improve the security protection level of the server by setting up error triggering mechanisms and error locking mechanisms.

[0005] In a first aspect, the present invention provides a security protection system, which includes: a lock body, a lock cylinder, a lock block, a locking mechanism, lock control accessories, an error triggering mechanism, and an error locking mechanism;

[0006] The lock body has a fixed cavity, in which the lock cylinder, lock block, and lock control accessories are all located. The lock cylinder has a lock cavity extending in the front-to-back direction, with its opening located on the front surface of the lock cylinder. The lock cylinder is rotatably connected to the lock body in the front-to-back direction. A locking mechanism is located on the rear side of the lock body and connected to the rear end of the lock cylinder. The locking mechanism is used to lock the first and second components when the lock cylinder rotates relative to the lock body in the front-to-back direction. When the lock cylinder rotates and the locking mechanism is in the first locking position, the locking mechanism locks the first and second components, fixing their relative positions. When the lock cylinder rotates and the locking mechanism is in the second locking position, the locking mechanism releases the locking of the first and second components. The lock block is fitted onto the outside of the lock cylinder and fixedly connected to the lock body; the fault triggering mechanism is movably connected to the lock control accessories. The lock block and lock cylinder, in conjunction with the key, provide the lock control components with a natural state position, a correct state position, and an incorrect state limit position; when no key is inserted into the lock cavity, the lock control components are in the natural state position; when the correct key is inserted into the lock cavity, the lock control components are in the correct state position; when the wrong key is inserted into the lock cavity, the wrong key can cause the lock control components to be in the incorrect state limit position. When the key positions the locking accessory in the correct state position, it can control the locking mechanism to switch between the first and second locking positions, and cause the error triggering mechanism to keep the first and second devices in the unlocked state through the error locking mechanism; when the key positions the locking accessory in the error state limit position, it can control the locking mechanism to switch between the first and second locking positions, and control the error triggering mechanism to drive the error locking mechanism, so that the error locking mechanism keeps the first and second devices in the locked state.

[0007] Optionally, the lock control components include: a lock control assembly and a rotor spring; a sliding hole is provided on the outer side wall of the lock cylinder, the sliding hole communicating with the lock cavity; a mounting groove is provided on the inner side wall of the lock block, the mounting groove communicating with the sliding hole; the lock control assembly is slidably connected to the lock block and the lock cylinder respectively in a direction perpendicular to the front and rear through the mounting groove and the sliding hole; the rotor spring is located in the mounting groove and on the side of the lock control assembly away from the lock cavity, and is used to apply a force toward the lock cavity to the lock control assembly; the lock control assembly is used to compress the rotor spring when the key is inserted into the lock cylinder from the opening; The lock block and lock cylinder, through the cooperation of mounting slots, sliding holes and keys, can provide the lock control components with natural state positions, correct state positions and error state limit positions; The lock control assembly located in the correct state position is on the side away from the lock cavity of the lock control assembly located in the natural state position, or is located in the same position as the lock control assembly located in the natural state position; the lock control assembly located in the error state limit position is on the side away from the lock cavity of the lock control assembly located in the correct state position. When the key positions the locking assembly in the correct state position, it can control the locking mechanism to switch between the first and second locking positions, and cause the error triggering mechanism to keep the first and second devices in the unlocked state through the error locking mechanism; when the key positions the locking assembly in the error state limit position, it can control the locking mechanism to switch between the first and second locking positions, and control the error triggering mechanism to drive the error locking mechanism so that the error locking mechanism keeps the first and second devices in the locked state.

[0008] Optionally, the locking assembly includes: an inner rotor and an outer rotor; The outer rotor is located on the side of the inner rotor facing the rotor spring and abuts against the inner rotor. Both the inner and outer rotors are slidably connected to the lock block and lock cylinder through mounting grooves and sliding holes. The lock block is fixedly connected to the lock body. When the locking assembly is in its natural working position, one end of the inner rotor is located in the lock cavity, the other end of the inner rotor is located in the sliding hole, one end of the outer rotor is located in the sliding hole, and the other end of the outer rotor is located in the mounting groove. When the lock control assembly is in the correct working position, one end of the inner rotor is located in the lock cavity, and the end face of the other end of the inner rotor is flush with the outer surface of the lock cylinder. One end of the outer rotor is flush with the outer surface of the lock cylinder, and the other end of the outer rotor is located in the mounting groove. When the locking assembly is in the error state limit position, one end face of the inner rotor is flush with the outer surface of the lock cylinder, the other end of the inner rotor is in the mounting groove, and the outer rotor is in the mounting groove.

[0009] Optionally, the security protection system further includes: a fixed block, which is located inside the fixed cavity and outside the lock cylinder, and is fixedly connected to the lock body. A trigger hole is provided on the fixed block along a first direction, which intersects with the front and rear directions. The error triggering mechanism includes: a trigger spring, a pressure block, a trigger rod, and an elastic locking element; a storage groove is provided on the side wall of the inner rotor, the trigger spring and the pressure block are both located in the storage groove, one end of the trigger spring abuts against the inner rotor, the other end of the trigger spring abuts against the pressure block, the pressure block slides and connects to the inner rotor along the first direction through the storage groove, and the elastic locking element is fixedly connected to the fixed locking block; The trigger rod slides and connects to the fixed block along the first direction through the trigger hole; when the locking assembly is not in the error state limit position, the storage slot does not completely coincide with the trigger hole in the first direction, the pressure block is located in the storage slot, the elastic clip limits the trigger rod in the fixed block, and separates the fixed block from the error locking mechanism; When the locking assembly is in the error state limit position, the storage slot is completely aligned with the trigger hole in the first direction. The trigger spring pushes the pressure block toward the storage slot so that the pressure block pushes the trigger rod to overcome the limitation of the elastic clip and move away from the trigger spring until it abuts against the error locking mechanism. The error locking mechanism is triggered to keep the first device and the second device in the locked state. The safety protection system also includes an error handling module; the error handling module is electrically connected to the error locking mechanism and is used to perform error handling operations when the trigger rod abuts against the error locking mechanism. The error handling operations include at least one of the following: alarm, remote alarm, data destruction, and data backup.

[0010] Optionally, the error locking mechanism includes: a magnetic sleeve, a storage battery, a locking component, and a motherboard; The rear end of the lock body is fixedly provided with a first contact point and a second contact point. The energy storage battery is fixedly connected to the lock body. The anode of the energy storage battery is electrically connected to the first contact point, and the cathode of the energy storage battery is electrically connected to the second contact point. The first contact point and the second contact point are electrically connected to the main board through cables. The locking component is electrically connected to the energy storage battery. The magnetic sleeve is fitted around the outer periphery of the lock cylinder, and the rear end of the magnetic sleeve engages with the rear end of the lock cylinder in a direction perpendicular to the front and rear, so as to switch between the first and second rotation positions with the lock cylinder; when the first and second devices are in the locked state, the magnetic sleeve moves to the first rotation position via the lock cylinder; when the first and second devices are in the unlocked state, the magnetic sleeve moves to the second rotation position via the lock cylinder. Multiple conductive areas extending in the front-to-back direction are formed on the side wall of the magnetic sleeve; the conductive areas are used to connect with the error triggering mechanism and extend to the rear end of the magnetic sleeve; when the magnetic sleeve moves to the first rotary station or the second rotary station, the first contact point and the second contact point are electrically connected to the corresponding conductive areas respectively. When the magnetic sleeve moves from the first rotary station to the second rotary station and the error triggering mechanism is connected to the error locking mechanism, the motherboard controls the locking component through the energy storage battery to keep the first device and the second device in a locked state.

[0011] Optionally, the locking assembly includes: an inductor coil, a latch, an electromagnetic induction rod, and a self-locking assembly; The inductor coil and the self-locking assembly are fixed on the first device and the second device, respectively. One end of the inductor coil is electrically connected to the anode of the storage battery, and the other end of the inductor coil is electrically connected to the cathode of the storage battery. One end of the electromagnetic induction rod is inserted into the inductor coil and can move relative to the inductor coil in the second direction. The locking tongue is fixedly connected to the end of the electromagnetic induction rod away from the inductor coil. When the magnetic sleeve moves from the first rotary station to the second rotary station and the error triggering mechanism is connected to the error locking mechanism, the motherboard controls the storage battery to discharge so that the inductor coil applies an Ampere force toward the self-locking assembly to the electromagnetic induction rod, pushing the latch toward the self-locking assembly to the first locking position; When the latch moves to the first locking position, the self-locking assembly locks the latch in the first locking position to prevent the electromagnetic induction rod from moving away from the latch and to keep the first and second devices in a locked state.

[0012] Optionally, the locking assembly also includes: a spring-loaded component and an unlocking guide; The unlocking guide is sleeved around the periphery of the electromagnetic induction rod and slides along the second direction to connect with the electromagnetic induction rod. The return spring is located on the side of the electromagnetic induction rod away from the lock tongue. One end of the return spring is fixedly connected to the electromagnetic induction rod, and the other end of the return spring is fixedly connected to the first device. The motherboard is used to increase the discharge power of the storage battery after receiving the correct login password, so that the electromagnetic induction rod pushes the unlocking guide to move towards the self-locking sub-assembly until the bolt reaches the second locking position; The mainboard is also used to stop the battery from supplying power to the inductor coil when the latch reaches the second locking position; The spring-loaded component applies a force away from the self-locking assembly to the electromagnetic induction rod. When the motherboard stops supplying power from the battery to the inductor coil, the unlocking guide drives the electromagnetic induction rod to move away from the self-locking assembly until the latch disengages from the self-locking assembly, thus releasing the locking assembly from locking the first and second devices.

[0013] Optionally, the self-locking sub-assembly includes: a self-locking body, a resilient compression member, and a latch; The lock body has a locking hole and a sliding hole. The locking hole extends along the second direction, and one end of the locking hole opens towards the inductor coil. The sliding hole extends along the third direction, and the third direction intersects with the second direction. Both the elastic compression element and the pin are located in the sliding hole. One end of the elastic compression element is fixedly connected to the self-locking body, and the other end of the elastic compression element is fixedly connected to one end of the pin. The pin slides and connects to the self-locking body through the sliding hole in a third direction. The elastic compression member is used to push the other end of the bolt into the lock hole so that when the bolt moves to the first locking position, it locks the bolt into the lock hole.

[0014] Optionally, when the bolt moves to the first locking position, the other end of the pin is located between the bolt and the unlocking guide and abuts against the bolt; The surface of the unlocking guide facing the spring is a guide slope; when the lock tongue is in the second locking position, it is in contact with the surface of the unlocking guide away from the spring.

[0015] In a second aspect, the present invention provides a server, the server including a first device, a second device, and a security protection system as described in any one of the first aspects; The safety protection system is connected to the first device and the second device respectively.

[0016] The security protection system and server provided in this invention, by setting up a locking accessory, an error triggering mechanism, and an error locking mechanism, can ensure that the locking accessory is in its natural state position when no key is inserted into the lock cavity; when the correct key is inserted into the lock cavity, the locking accessory is in its correct state position, at which time the key can control the locking mechanism to switch between the first and second locking positions, and the error triggering mechanism keeps the first and second devices in the unlocked state through the error locking mechanism; when an incorrect key is inserted into the lock cavity, the incorrect key can cause the locking accessory to be in the error state limit position. At this time, although the key can still control the locking mechanism to switch between the first and second locking positions, it will also trigger the error triggering mechanism, so that the error locking mechanism keeps the first and second devices in the locked state, thereby effectively preventing the occurrence of incorrect keys or devices with non-key structures attempting to switch the first and second devices from the locked state to the unlocked state, thus improving the security protection level of the server when the first and second devices serve as the server's casing.

[0020] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0022] Spatial relation terms such as "below," "under," "below," "below," "above," and "above" are used here to describe the relationship between one element or feature shown in the figure and other elements or features. Similarly, "directly above" can be used here to describe an element or feature shown in the figure that coincides in a vertical straight line direction, which may be partial or complete, depending on the actual situation or the content of the illustration. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation. For example, if the device in the figure is flipped, the element or feature described as "below," "below," or "below" of other elements will be oriented "above" other elements or features. Therefore, the exemplary terms "below" and "below" can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0023] It should be noted that when an element is referred to as "fixedly connected" to another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is referred to as being "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0024] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0025] Firstly, the present invention provides a security protection system, combined with Figure 1 , Figure 2 , Figure 3 and Figure 4The security protection system includes: 1. Lock body, 2. Lock cylinder, 3. Locking block, 4. Locking mechanism, 5. Locking control accessories, 6. Error triggering mechanism, and 7. Error locking mechanism.

[0026] A fixed cavity 11 is formed inside the lock body 1. The lock cylinder 2, lock block 3, and lock control accessories 5 are all located inside the fixed cavity 11. A lock cavity 21 extending in the front-rear direction is formed inside the lock cylinder 2. The opening of the lock cavity 21 is located on the front surface of the lock cylinder 2. The lock cylinder 2 is rotatably connected to the lock body 1 in the front-rear direction. The locking mechanism 4 is located on the rear side of the lock body 1 and is connected to the rear end of the lock cylinder 2. The locking mechanism 4 is used to lock the first device 91 and the second device 92 when the lock cylinder 2 rotates relative to the lock body 1 in the front-rear direction. When the lock cylinder 2 rotates and the locking mechanism 4 is in the first locking position, the locking mechanism 4 locks the first device 91 and the second device 92 so that the positions of the first device 91 and the second device 92 are relatively fixed; when the lock cylinder 2 rotates and the locking mechanism 4 is in the second locking position, the locking mechanism 4 releases the locking of the first device 91 and the second device 92.

[0027] The lock block 3 is sleeved on the outside of the lock cylinder 2 and fixedly connected to the lock body 1. The error triggering mechanism 6 is movably connected to the lock control accessory 5.

[0028] Lock block 3 and lock cylinder 2, in cooperation with the key, can provide the lock control accessory 5 with a natural state position, a correct state position, and an incorrect state limit position; when no key is inserted into the lock cavity 21, the lock control accessory 5 is in the natural state position; when the correct key is inserted into the lock cavity 21, the lock control accessory 5 is in the correct state position; when the wrong key is inserted into the lock cavity 21, the wrong key can cause the lock control accessory 5 to be in the incorrect state limit position.

[0029] When the key positions the locking accessory 5 in the correct state position, it can control the locking mechanism 4 to switch between the first locking position and the second locking position, and cause the error triggering mechanism 6 to keep the first device 91 and the second device 92 in the unlocked state through the error locking mechanism 7; when the key positions the locking accessory 5 in the error state limit position, it can control the locking mechanism 4 to switch between the first locking position and the second locking position, and control the error triggering mechanism 6 to drive the error locking mechanism 7, so that the error locking mechanism 7 keeps the first device 91 and the second device 92 in the locked state.

[0030] The security protection system and server provided in this embodiment of the invention, by setting up a locking accessory 5, an error triggering mechanism 6, and an error locking mechanism 7, can ensure that the locking accessory 5 is in its natural state position when no key is inserted into the lock cavity 21; when the correct key is inserted into the lock cavity 21, the locking accessory 5 is in its correct state position, at which time the key can control the locking mechanism 4 to switch between the first locking position and the second locking position, and the error triggering mechanism 6 keeps the first device 91 and the second device 92 in the unlocked state through the error locking mechanism 7; when an incorrect key is inserted into the lock cavity 21, the incorrect key can cause the locking accessory 5 to be in the error state limit position. At this time, although the key can still control the locking mechanism 4 to switch between the first locking position and the second locking position, it will also trigger the error triggering mechanism 6, so that the error locking mechanism 7 keeps the first device 91 and the second device 92 in the locked state, thereby effectively avoiding the occurrence of incorrect keys or devices with non-key structures attempting to switch the first device 91 and the second device 92 from the locked state to the unlocked state, thereby improving the security protection level of the server when the first device 91 and the second device 92 serve as the server casing.

[0031] It is understood that when the first device 91 and the second device 92 are in the locked state, it means that the first device 91 and the second device 92 are in a state where they cannot move relative to each other; when the first device 91 and the second device 92 are in the unlocked state, it means that the first device 91 and the second device 92 are in a state where they can move relative to each other. The front-back direction mentioned above refers to the axial direction of the lock cylinder 2. The front-back direction can be adjusted according to the specific installation orientation of the lock cylinder 2.

[0032] In this embodiment, there are two lock blocks 3, which are located on the upper and lower sides of the lock cylinder 2 respectively, and cover the periphery of the lock cylinder 2 in the front-to-back direction.

[0033] In a further optional embodiment of this embodiment, combined with Figure 1 , Figure 5 and Figure 6 The lock control component 5 includes a lock control assembly 51 and a rotor spring 52. A sliding hole 22 is provided on the outer wall of the lock cylinder 2. The sliding hole 22 communicates with the lock cavity 21. A mounting groove 31 is provided on the inner wall of the lock block 3. The mounting groove 31 and the sliding hole 22 extend and communicate in a direction perpendicular to the front and rear. The lock control assembly 51 is slidably connected to the lock block 3 and the lock cylinder 2 respectively in a direction perpendicular to the front and rear through the mounting groove 31 and the sliding hole 22. The rotor spring 52 is located within the mounting groove 31 and on the side of the lock control assembly 51 away from the lock cavity 21, and is used to apply a force toward the lock cavity 21 to the lock control assembly 51. The lock control assembly 51 is used to compress the rotor spring 52 when the key is inserted into the lock cylinder 2 from the opening, so that the rotor spring 52 applies a force toward the lock cylinder 2 to the lock control assembly 51, thereby stabilizing the lock control assembly 51 within the cavity formed by the mounting groove 31 and the sliding hole 22.

[0034] It is understood that one or more sets of locking components 51 may be provided within the fixed cavity 11, and each set of locking components 51 may include one or more locking components 51. In this embodiment, two sets of locking components 51 are provided within the fixed cavity 11, symmetrically arranged along the horizontal plane. Each set of locking components 51 includes multiple locking components 51, and the multiple locking components 51 in each set are arranged in the front-back direction. Specifically, each set of locking components 51 includes five locking components 51 arranged at equal intervals. Each locking component 51 corresponds to a mounting groove 31 and a sliding hole 22, and corresponds to an error triggering mechanism 6.

[0035] The lock block 3 and lock cylinder 2, through the cooperation of the mounting slot 31, sliding hole 22 and key, can provide the lock control assembly 51 with a natural state position, a correct state position and an error state limit position.

[0036] The lock control assembly 51 located in the correct state position is on the side opposite to the lock cavity 21 of the lock control assembly 51 in the natural state position, or is located in the same position as the lock control assembly 51 in the natural state position; the lock control assembly 51 located in the error state limit position is on the side opposite to the lock cavity 21 of the lock control assembly 51 in the correct state position. It is understood that when the correct key is inserted, the key may move one or more lock control assemblies 51 to the natural state position, or none of the lock control assemblies 51 may move to the natural state position. In this embodiment, all lock control assemblies 51 located in the correct state position are on the side opposite to the lock cavity 21 of the lock control assembly 51 in the natural state position.

[0037] Combination Figure 4 , Figure 5 and Figure 6 When the key positions the locking assembly 51 in the correct state position, it can control the locking mechanism 4 to switch between the first locking position and the second locking position, and cause the error triggering mechanism 6 to keep the first device 91 and the second device 92 in the unlocked state through the error locking mechanism 7; when the key positions the locking assembly 51 in the error state limit position, it can control the locking mechanism 4 to switch between the first locking position and the second locking position, and control the error triggering mechanism 6 to drive the error locking mechanism 7, so that the error locking mechanism 7 keeps the first device 91 and the second device 92 in the locked state.

[0038] It is understood that after the lock cylinder 2 is installed onto the lock body 1, both the lock cylinder 2 and the lock block 3 are fixedly connected to the lock body 1 in the front-to-back direction. In this embodiment, the error triggering mechanism 6 is located within the fixed cavity 11.

[0039] By setting a locking control assembly 51 and a rotor spring 52 between the lock block 3 and the lock cylinder 2, the connection relationship between the lock cylinder 2 and the lock block 3 can be effectively controlled. Specifically, under the action of the rotor spring 52 and the corresponding key, the locking control assembly 51 can move to one of the following positions: a natural state position, a correct state position, and an incorrect state limit position. When the locking control assembly 51 moves to the natural state position under the action of the rotor spring 52 and the key, the lock cylinder 2 is relatively fixed relative to the lock block 3 in the relative front-back rotation direction. When the locking control assembly 51 moves to the correct state position or the incorrect state limit position under the action of the rotor spring 52 and the key, the lock cylinder 2 can rotate relative to the lock block 3 in the front-back direction.

[0040] In a further optional embodiment of this embodiment, combined with Figure 5 , Figure 6 and Figure 7 The locking assembly 51 includes an inner rotor 511 and an outer rotor 512. The outer rotor 512 is located on the side of the inner rotor 511 facing the rotor spring 52 and abuts against the inner rotor 511. Both the inner rotor 511 and the outer rotor 512 are slidably connected to the lock block 3 and the lock cylinder 2 in a direction perpendicular to the front and rear through the mounting groove 31 and the sliding hole 22.

[0041] When the locking assembly 51 is in its natural state position, one end of the inner rotor 511 is located in the locking cavity 21, the other end of the inner rotor 511 is located in the sliding hole 22, one end of the outer rotor 512 is located in the sliding hole 22, and the other end of the outer rotor 512 is located in the mounting groove 31.

[0042] When the locking assembly 51 is in the correct working position, one end of the inner rotor 511 is located in the lock cavity 21, the end face of the other end of the inner rotor 511 is flush with the outer surface of the lock cylinder 2, the end face of one end of the outer rotor 512 is flush with the outer surface of the lock cylinder 2, and the other end of the outer rotor 512 is located in the mounting groove 31.

[0043] When the locking assembly 51 is in the error state limit position, the end face of one end of the inner rotor 511 is flush with the outer surface of the lock cylinder 2, the other end of the inner rotor 511 is located in the mounting groove 31, and the outer rotor 512 is located in the mounting groove 31.

[0044] By setting the inner rotor 511 and the outer rotor 512, when the locking assembly 51 is in the natural state position, the two ends of the outer rotor 512 are respectively inserted into the mounting groove 31 and the sliding hole 22, thereby effectively preventing the lock cylinder 2 from rotating relative to the lock block 3, so that the lock cylinder 2 always remains in the natural state, so that the first device 91 and the second device 92 remain in the locked state.

[0045] When the locking assembly 51 is in the correct operating position, the outer rotor 512 and the inner rotor 511 are respectively located in the mounting groove 31 and the sliding hole 22, and the contact surfaces of the outer rotor 512 and the inner rotor 511 are flush with the outer surface of the lock cylinder 2, thereby allowing the lock cylinder 2 to rotate relative to the lock block 3. This allows the lock cylinder 2 to rotate relative to the lock block 3 in the front-to-back direction under the drive of the key, and to switch between the unlocked and unlocked states. In the unlocked state, the lock cylinder 2 controls the locking mechanism 4 to be in the second locking position to release the locking mechanism 4 from locking the first device 91 and the second device 92.

[0046] When the lock control assembly 51 is in the correct working position, both the outer rotor 512 and the inner rotor 511 are located in the mounting groove 31, and the inner rotor 511 is located outside the lock cylinder 2 or flush with the outer surface of the lock cylinder 2, so that the lock cylinder 2 can rotate relative to the lock block 3, so that the lock cylinder 2 can rotate relative to the lock block 3 in the front-back direction under the drive of the key, and switch between the natural state and the unlocked state.

[0047] In a further optional embodiment of this embodiment, combined with Figure 1 , Figure 3 and Figure 7 The security protection system also includes a fixing block 82. The fixing block 82 is located inside the fixing cavity 11 and outside the lock cylinder 2 and the lock block 3. The fixing block 82 is fixedly connected to the lock body 1. A trigger hole 821 is provided on the fixing block 82 along the first direction, which intersects with the front and rear direction.

[0048] In this embodiment, the fixing block 82 is composed of two symmetrically arranged block structures, which are located on the left and right sides of the lock block 3 respectively, so as to fix the lock block 3 in the fixing cavity 11; the first direction is perpendicular to the front and back direction, specifically the left and right direction; the trigger hole 821 is opened on the upper and lower sides of the lock cylinder 2 and passes through the fixing block 82 and the corresponding lock block 3 along the first direction.

[0049] The error triggering mechanism 6 includes: a trigger spring 61, a pressure block 62, a trigger rod 63, and an elastic locking member 64. A storage groove 5111 is provided on the side wall of the inner rotor 511. The trigger spring 61 and the pressure block 62 are both located in the storage groove 5111. One end of the trigger spring 61 abuts against the inner rotor 511, and the other end of the trigger spring 61 abuts against the pressure block 62 through the guide hole 32 on the locking block 3. The pressure block 62 is slidably connected to the inner rotor 511 along the first direction through the storage groove 5111. The elastic locking member 64 is fixedly connected to the fixed locking block 82.

[0050] The trigger rod 63 is slidably connected to the fixed block 82 along the first direction through the trigger hole 821; when the locking assembly 51 is not in the error state limit position, the storage groove 5111 does not completely coincide with the trigger hole 821 in the first direction, the pressure block 62 is located in the storage groove 5111, the elastic locking member 64 limits the trigger rod 63 in the fixed block 82, and separates the fixed block 82 from the error locking mechanism 7.

[0051] When the locking assembly 51 is in the error state limit position, the storage slot 5111 is completely aligned with the trigger hole 821 in the first direction. The trigger spring 61 pushes the pressure block 62 toward the storage slot 5111, so that the pressure block 62 pushes the trigger rod 63 to overcome the limitation of the elastic clip 64 and move away from the trigger spring 61 until it abuts against the error locking mechanism 7. The error locking mechanism 7 is triggered to keep the first device 91 and the second device 92 in the locked state.

[0052] It should be noted that there can be one or more error triggering mechanisms 6, and one or two error triggering mechanisms 6 can be set on the same inner rotor 511.

[0053] It is understandable that when only one error triggering mechanism 6 is set in the fixed cavity 11, the lock cylinder 2 can only switch from the natural state to the unlocked state under the action of the corresponding key when the lock control component 51 connected to the error triggering mechanism 6 moves to the error state limit position and the other lock control components 51 move to the error state limit position or the correct state position. When the lock cylinder 2 switches from the natural state to the unlocked state, the error triggering mechanism 6 can trigger the error locking mechanism 7 to keep the first device 91 and the second device 92 in the locked state.

[0054] When multiple error triggering mechanisms 6 are provided in the fixed cavity 11, as long as at least one error triggering mechanism 6 connected to the lock control component 51 moves to the error state limit position, and the other lock control components 51 move to the error state limit position or the correct state position, the lock cylinder 2 can switch from the natural state to the unlocked state under the drive of the corresponding key. When the lock cylinder 2 switches from the natural state to the unlocked state, the error triggering mechanism 6 corresponding to the lock control component 51 that moves to the error state limit position can trigger the error locking mechanism 7 to keep the first device 91 and the second device 92 in the locked state.

[0055] In this embodiment, each inner rotor 511 is symmetrically provided with an error triggering mechanism 6 on the left and right sides relative to the axis of the inner rotor 511; the surface of the trigger rod 63 is provided with multiple teeth along the first direction; the elastic locking member 64 includes a locking pin 641 and a compression spring 642; the locking pin 641 is pivotally connected to the fixed locking block 82 along the first direction; one end of the locking pin 641 is locked with the trigger rod 63 in the first direction through the teeth; the other end of the locking pin 641 is fixedly connected to the compression spring 642; and the other end of the compression spring 642 is fixedly connected to the fixed locking block 82.

[0056] When the locking assembly 51 moves to the error state limit position, the pressure block 62 pushes the trigger rod 63 to move away from the inner rotor 511 under the action of the trigger spring 61, so that the trigger rod 63 overcomes the limitation of the elastic clip 64 and moves away from the trigger spring 61 until it abuts against the error locking mechanism 7.

[0057] When the locking assembly 51 has not moved to the error state limit position, the locking pin 641, driven by the compression spring 642, engages with the trigger rod 63 in the first direction through teeth, so as to limit the trigger rod 63 within the storage slot 5111.

[0058] In a further optional embodiment of this embodiment, combined with Figure 1 , Figure 4 and Figure 8 The security protection system also includes an error handling module 81; the error handling module 81 is electrically connected to the error locking mechanism 7 and is used to perform error handling operations when the trigger rod 63 abuts against the error locking mechanism 7. The error handling operations include at least one of the following: alarm, remote alarm, data destruction, and data backup.

[0059] It should be noted that the error triggering mechanism 6 can activate the error locking mechanism 7 to keep the first device 91 and the second device 92 in a locked state by contact or by intermittent sensing. Specifically, when one or more error triggering mechanisms 6 are in contact with or sensing the error locking mechanism 7, the error locking mechanism 7 can be controlled to keep the first device 91 and the second device 92 in a locked state.

[0060] In this embodiment, the error triggering mechanism 6 controls the error locking mechanism 7 to keep the first device 91 and the second device 92 in a locked state through contact. Specifically, when the trigger rod 63 contacts the error locking mechanism 7, the error locking mechanism 7 keeps the first device 91 and the second device 92 in a locked state. Meanwhile, the error handling module 81 includes an alarm unit, a remote alarm unit, a data destruction unit, and a data backup unit to respectively implement error handling operations such as alarm, remote alarm, data destruction, and data backup.

[0061] In a further optional embodiment of this embodiment, combined with Figure 1 , Figure 2 , Figure 5 and Figure 8 The error locking mechanism 7 includes: a magnetic sleeve 71, a storage battery 72, a locking component 73, and a main board 74.

[0062] Combination Figure 5 and Figure 9 The rear end of the lock body 1 is fixedly provided with a first contact point 12 and a second contact point 13. A storage battery 72 is fixedly connected to the lock body 1. The anode of the storage battery 72 is electrically connected to the first contact point 12 via a first electrical structure 15 on the rear end of the lock body 1, and the cathode of the storage battery 72 is electrically connected to the second contact point 13 via a second electrical structure 16 on the rear end of the lock body 1. The first contact point 12 and the second contact point 13 are respectively electrically connected to the main board 74 via cables 14. The first electrical structure 15 and the second electrical structure 16 are obtained by electroplating the inner rear end of the lock body 1.

[0063] The magnetic sleeve 71 is fitted around the outer periphery of the lock cylinder 2 and located within the fixed cavity 11. The main board 74 is fixedly disposed on the outer side of the lock body 1. The rear end of the magnetic sleeve 71 engages with the rear end of the lock cylinder 2 in a direction perpendicular to the front and rear, so as to switch between the first rotation position and the second rotation position with the lock cylinder 2. Specifically, when the first device 91 and the second device 92 are in the locked state, the magnetic sleeve 71 moves to the first rotation position via the lock cylinder 2; when the first device 91 and the second device 92 are in the unlocked state, the magnetic sleeve 71 moves to the second rotation position via the lock cylinder 2.

[0064] Combination Figure 7 , Figure 9 and Figure 10 Multiple conductive regions 711 extending in the front-to-back direction are formed on the side wall of the magnetic sleeve 71. The conductive regions 711 are used to connect with the error triggering mechanism 6 and extend to the rear end of the magnetic sleeve 71; when the magnetic sleeve 71 moves to the first rotary station or the second rotary station, the first contact point 12 and the second contact point 13 are electrically connected to the corresponding conductive regions 711 respectively.

[0065] When the magnetic sleeve 71 moves from the first rotary station to the second rotary station and the error triggering mechanism 6 is connected to the error locking mechanism 7, the mainboard 74 controls the locking component 73 to keep the first device 91 and the second device 92 in a locked state.

[0066] It is understood that the different conductive areas 711 are independent of each other, and every two conductive areas 711 correspond to a set of locking components 51. In this embodiment, the trigger rod 63 is made of conductive material; four conductive areas 711 are formed on the magnetic sleeve 71; there are two energy storage batteries 72, namely the upper battery 721 and the lower battery 722, and both energy storage batteries 72 are fixedly installed in the fixed cavity 11 and fixedly connected to the lock outer body 1. The fixed block 82 has an annular cavity 822 inside, and the opening of the annular cavity 822 is located on the rear end face of the fixed block 82. The front end, i.e., the side wall, of the magnetic sleeve 71 is inserted into the annular cavity 822 and rotated and connected to the fixed block 82 in the front-back direction.

[0067] The four conductive areas 711 form a square at its four corners in a vertical plane, meaning they are centrally symmetrical. There are two first contact points 12 and two second contact points 13, which are alternately arranged around the lock cylinder 2 and detachably connected to the lock body 1. The upper battery 721 is located on the upper side of the lock cylinder 2, and the lower battery 722 is also located on the upper side of the lock cylinder 2. The anodes and cathodes of the two batteries 72 are electrically connected to a set of first contact points 12 and second contact points 13, respectively. The cathodes and anodes of both batteries 721 and 722 are exposed on the rear wall of the lock body 1 via metal rods 723. The first contact points 12 and 13 are led out from the rear wall of the lock body 1 via cables 14 and electrically connected to the main board 74.

[0068] When any trigger lever 63 contacts the magnetic sleeve 71, the trigger lever 63 will cause a potential fluctuation on the pins of the main board 74 that are electrically connected to the first contact contact 12 or / and the second contact contact 13 through the corresponding conductive area 711 and the first contact contact 12 or / and the second contact contact 13. When the main board 74 detects a potential fluctuation, it starts to determine whether the key drives the lock cylinder 2 to rotate. When it detects that the key drives the lock cylinder 2 to rotate, it will control the locking component 73 to keep the first device 91 and the second device 92 in a locked state until human intervention releases the locking component 73 from locking the first device 91 and the second device 92, or the main board 74 stops controlling the locking component 73.

[0069] The principle by which the mainboard 74 monitors whether the key drives the lock cylinder 2 to rotate is to detect whether the direction of the magnetic field generated by the magnetic sleeve 71 changes relative to the mainboard 74. When the key drives the lock cylinder 2 to rotate, the magnetic sleeve 71 will also rotate synchronously. At this time, the mainboard 74 will detect whether the magnetic sleeve 71 is rotating relative to the lock body 1 and whether the specific angle of rotation of the magnetic sleeve 71 reaches the trigger requirement through the first contact contact 12 and the second contact contact 13 that abut against the magnetic sleeve 71. The specific angle at which the magnetic sleeve 71 triggers the mainboard to detect the key driving the lock cylinder 2 to rotate can be between 10 degrees and 30 degrees. This embodiment does not make a specific limitation on this.

[0070] In a further optional embodiment of this embodiment, combined with Figure 2 , Figure 5 and Figure 6 The locking assembly 73 includes: an inductor coil 731, a locking tongue 732, an electromagnetic induction rod 733, and a self-locking component 734.

[0071] The inductor coil 731 and the self-locking assembly 734 are respectively fixed to the first device 91 and the second device 92. One end of the inductor coil 731 is electrically connected to the anode of the upper battery 721, and the other end of the inductor coil 731 is electrically connected to the cathode of the upper battery 721. One end of the electromagnetic induction rod 733 is inserted into the inductor coil 731 and can move relative to the inductor coil 731 in a second direction. The locking tongue 732 is fixedly connected to the end of the electromagnetic induction rod 733 away from the inductor coil 731.

[0072] It is understandable that when the inductor coil 731 is fixed to the first device 91, the self-locking assembly 734 is fixedly disposed on the second device 92. When the inductor coil 731 is fixed to the second device 92, the self-locking assembly 734 is fixedly disposed on the first device 91.

[0073] In this embodiment, the second direction is the up-down direction; the first device 91 is located below the second device 92; the inductor coil 731, the locking tongue 732 and the electromagnetic induction rod 733 are all located directly below the self-locking assembly 734, and the inductor coil 731 and the self-locking assembly 734 are respectively fixed on the first device 91 and the second device 92.

[0074] When the magnetic sleeve 71 moves from the first rotary station to the second rotary station and the error triggering mechanism 6 is connected to the error locking mechanism 7, the main board 74 controls the storage battery 72 to discharge so that the inductor coil 731 applies an upward Ampere force to the electromagnetic induction rod 733, pushing the locking tongue 732 upward to the first locking position.

[0075] When the latch 732 moves to the first locking position, the self-locking assembly 734 locks the latch 732 in the first locking position to prevent the electromagnetic induction rod 733 from moving away from the latch 732, and keeps the first device 91 and the second device 92 in a locked state.

[0076] In this embodiment, when the locking tongue 732 is in the first locking position, the top of the locking tongue 732 is inserted into the self-locking component 734, and the self-locking component 734 engages with the locking tongue 732 in the horizontal direction to limit the locking tongue 732 in the second direction, thereby achieving the effect of keeping the first device 91 and the second device 92 in a locked state.

[0077] In a further optional embodiment of this embodiment, the locking component 73 further includes a spring-back member 735 and an unlocking guide member 736.

[0078] The unlocking guide 736 is sleeved around the periphery of the electromagnetic induction rod 733 and slides vertically with the electromagnetic induction rod 733. The spring-loaded member 735 is located on the side of the electromagnetic induction rod 733 opposite to the latch 732. The top end of the spring-loaded member 735 is fixedly connected to the electromagnetic induction rod 733, and the bottom end of the spring-loaded member 735 is fixedly connected to the first device 91. In this embodiment, the spring-loaded member 735 is a helical spring; the bottom end of the spring-loaded member 735 penetrates the top of the lock body 1 and abuts against the upper battery 721.

[0079] The main board 74 is used to increase the discharge power of the storage battery 72 after receiving the correct login password, so that the electromagnetic induction rod 733 pushes the unlocking guide 736 toward the self-locking assembly 734 until the bolt 732 reaches the second locking position. The main board 74 is also used to stop the storage battery 72 from supplying power to the inductor coil 731 when the bolt 732 reaches the second locking position.

[0080] The spring-loaded member 735 is used to apply a force away from the self-locking assembly 734 to the electromagnetic induction rod 733 so that when the main board 74 stops the power supply from the storage battery 72 to the inductor coil 731, the unlocking guide member 736 drives the electromagnetic induction rod 733 to move away from the self-locking assembly 734 until the locking tongue 732 disengages from the self-locking assembly 734, thereby releasing the locking assembly 73 from locking the first device 91 and the second device 92.

[0081] By setting the spring-loaded component 735 and the unlocking guide component 736, and cooperating with the main board 74 to control the discharge state of the storage battery 72, the error locking mechanism 7 can automatically keep the first device 91 and the second device 92 in a locked state when it is triggered, and automatically unlock the first device 91 and the second device 92 after the user enters the correct login password.

[0082] It is understandable that the self-locking component 734 can control the latch 732 through a purely mechanical structure, or it can control the latch 732 through a combination of mechanical and electrical control.

[0083] In a further optional embodiment of this embodiment, combined with Figure 4 , Figure 11 and Figure 12 The self-locking component 734 includes: a self-locking body 7341, an elastic compression member 7342, and a pin 7343.

[0084] The lock body 7341 has a locking hole 73411 and a sliding hole 73412. The locking hole 73411 extends along a second direction, with one end opening towards the inductor coil 731. The sliding hole 73412 extends along a third direction, which intersects with the second direction. In this embodiment, the third direction is perpendicular to the second direction.

[0085] Both the elastic compression member 7342 and the pin 7343 are located within the sliding hole 73412. One end of the elastic compression member 7342 is fixedly connected to the self-locking body 7341, and the other end of the elastic compression member 7342 is fixedly connected to one end of the pin 7343. The pin 7343 is slidably connected to the self-locking body 7341 through the sliding hole 73412 in a third direction. The elastic compression member 7342 is used to push the other end of the pin 7343 into the locking hole 73411, so that when the bolt 732 moves to the first locking position, it locks the bolt 732 into the locking hole 73411.

[0086] It is understood that the elastic compression member 7342 and the pin 7343 are arranged in pairs in the self-locking body 7341. In this embodiment, a total of four pairs of elastic compression members 7342 and pins 7343 are arranged in the front-back and left-right directions in the self-locking body 7341; the self-locking body 7341 is also provided with a first fixing pin 7344 and a second fixing pin 7345.

[0087] A locking hole 73413 is provided on the side wall of the self-locking body 7341. The locking hole 73413 passes through the self-locking body 7341 in a direction perpendicular to the sliding hole 73412 and communicates with the sliding hole 73412. In this embodiment, the first fixing pin 7344 is detachably connected to the end of the locking pin 7343 away from the locking hole 73411, and the other end of the elastic compression member 7342 is fixedly connected to the first fixing pin 7344. The second fixing pin 7345 is inserted into the self-locking body 7341 in a horizontal direction through the locking hole 73413, and one end of the elastic compression member 7342 is fixedly connected to the second fixing pin 7345.

[0088] By setting up an elastic compression member 7342 and a pin 7343, the elastic compression member 7342 inserts the other end of the pin 7343 into the lock hole 73411 in its natural state, thereby enabling the pin 7343 to stably limit the top of the bolt 732 within the lock hole 73411, ensuring the locking effect of the self-locking component 734 on the bolt 732.

[0089] Furthermore, in combination Figure 6 The surface of the unlocking guide 736 opposite to the bolt 732 is provided with a guide surface 7361 so that the unlocking guide 736 can push the bolt 7343 to move away from the lock guide 736 during the downward movement.

[0090] The surface of the unlocking guide 736 facing the bolt 732 is adapted to the surface of the bolt 732 facing the unlocking guide 736, or the projection of the position of the unlocking guide 736 in contact with the pin 7343 on the horizontal plane is located outside the projection of the bolt 732 on the horizontal plane, so that when the spring member 735 drives the bolt 732 to move downward, the pin 7343 moves directly above the bolt 732 under the guidance of the unlocking guide 736, thereby disengaging the bolt 732 from the self-locking assembly 734.

[0091] In a further optional embodiment of this embodiment, when the latch 732 moves to the first locking position, the other end of the pin 7343 is located between the latch 732 and the unlocking guide 736, and abuts against the latch 732. The surface of the unlocking guide 736 facing the spring-loaded member 735 is a guide slope; when the latch 732 is in the second locking position, it is in contact with the surface of the unlocking guide 736 that is away from the spring-loaded member 735.

[0092] In a further optional embodiment of this embodiment, combined with Figure 2 , Figure 4 and Figure 13 The locking mechanism 4 includes: a first locking element 41, a second locking element 42, and a linkage component 43.

[0093] The first locking element 41 is fixedly connected to the first device 91, the second locking element 42 is fixedly connected to the second device 92, one end of the linkage component 43 is connected to the first locking element 41 or the second locking element 42, and the other end of the linkage component 43 is connected to the rear end of the lock cylinder 2.

[0094] When the lock cylinder 2 rotates relative to the lock body 1 in the front-to-back direction, it drives the first locking member 41 or the second locking member 42 to move through the linkage component 43, so as to switch the first locking member 41 and the second locking member 42 between the locking position and the unlocking position.

[0095] When the locking mechanism 4 is in the first locking control position, the first locking fastener 41 and the second locking fastener 42 are in the locking position, and the first locking fastener 41 and the second locking fastener 42 together switch the first device 91 and the second device 92 to the locked state; when the locking mechanism 4 is in the second locking control position, the first locking fastener 41 and the second locking fastener 42 are in the unlocking position, and the first locking fastener 41 and the second locking fastener 42 together switch the first device 91 and the second device 92 to the unlocked state.

[0096] In a further optional embodiment of this example, the linkage component 43 includes a gear 431 and a rack 432. Both the gear 431 and the rack 432 are located on the outer side of the lock body 1. The gear 431 is coaxially and fixedly connected to the lock cylinder 2. The first locking fastener 41 is fixedly connected to the rack 432. The rack 432 meshes with the gear 431 and is slidably connected to the lock body 1 along the locking direction via the first locking fastener 41. The locking direction is perpendicular to the stacking direction of the first device 91 and the second device 92.

[0097] One end of the second locking member 42 is fixedly connected to the second device 92. A locking hole 421 is provided on the side wall of the other end of the second locking member 42, extending through the other end of the second locking member 42 in the locking direction. A rack 432 is adapted to the locking hole 421. When the lock cylinder 2 is in its natural state, the rack 432 is inserted into the locking hole 421 in the locking direction to engage with the second locking member 42 in the stacking direction of the first device 91 and the second device 92, thereby keeping the first device 91 and the second device 92 in a locked state. When the lock cylinder 2 is in the unlocked state, the rack 432 separates from the second locking member 42 in the stacking direction, thereby keeping the first device 91 and the second device 92 in a locked state.

[0098] In this embodiment, the locking hole 421 passes through the second locking member 42 along the locking direction; the locking direction is the left-right direction.

[0099] Furthermore, the locking mechanism 4 also includes a fixing plate 433. The fixing plate 433 is located on the outside of the lock body 1 and is fixedly connected to the lock body 1. The fixing plate 433 is also provided with a guide hole 4331. The rack 432 is slidably connected to the second locking member 42 along the locking direction through the guide hole 4331. In this embodiment, there are two fixing plates 433, which are located on the left and right sides of the lock body 1 respectively, and the rack 432 is slidably connected to the two fixing plates 433 respectively along the locking direction.

[0100] It should be noted that, in combination Figure 4 , Figure 7 , Figure 8All functions of the aforementioned motherboard 74 can be implemented by setting existing circuit modules on the motherboard 74. It can be understood that the motherboard 74 is equipped with a control module 741, a signal converter 742, a power input 743, and a battery charging and discharging switching circuit 744.

[0101] The control module 741 is electrically connected to the error handling module 81, the signal converter 742, and the battery charge / discharge switching circuit 744. The power input 743 is electrically connected to the upper battery 721 and the lower battery 722 via the battery charge / discharge switching circuit 744. The control module 741 is electrically connected to the battery charge / discharge switching circuit 744, and when the magnetic sleeve 71 is in the first rotating position, it controls the external power supply connected to the power input 743 to power the upper battery 721 and the lower battery 722 to charge them. The signal converter 742 is electrically connected to the first contact contact 12 and the second contact contact 13, and senses changes in the magnetic field signals of the first contact contact 12 and the second contact contact 13, converting the received magnetic field signals into pulse signals and transmitting them to the control module 741. When the trigger rod 63 contacts the magnetic sleeve 71, the control module 741... The first contact contact 12 and the second contact contact 13 can detect short-term fluctuations in the current flowing through the upper battery 721 and the lower battery 722. When the control module 741 detects short-term fluctuations in the current flowing through the upper battery 721 and the lower battery 722, it can confirm that at least one locking accessory 5 has moved to the error state limit position. At the same time, the control module 741 identifies whether the magnetic sleeve 71 is rotating from the first rotating position to the second rotating position based on the change of the pulse signal. When the magnetic sleeve 71 is detected to be rotating to the second rotating position, the external power supply to the upper battery 721 and the lower battery 722 is stopped, and the upper battery 721 is controlled to discharge. This controls the locking component 73 to keep the first device 91 and the second device 92 in the locked state. At the same time, a trigger signal is sent to the error processing module 81 so that the error processing module 81 can perform error processing operations.

[0102] In this embodiment, the control module 741 is also electrically connected to the password input module. When the control module 741 receives the correct password input by the user through the password input module, it controls the upper battery 721 to instantly increase its discharge power through the battery charge / discharge switching circuit 744, thereby releasing the locking component 73 from locking the first device 91 and the second device 92. The control module 741 includes a central processing unit (CPU) and an EC (Embedded Controller). The EC is connected to the CPU via an eSPI / LPC bus, forming a complete embedded control system. This system includes functions such as power management, timing control, and PWM (Pulse-Width Modulation) control, all of which can be implemented using existing technologies and will not be elaborated upon in this embodiment.

[0103] The security system provided in this embodiment adds an error triggering mechanism 6 and an error locking mechanism 7 to the locking mechanism 4. Even if an incorrect key is used to switch the lock cylinder 2 from the natural state to the unlocked state, the first component 91 and the second component 92 cannot be directly separated. Specifically, when an incorrect key, such as a wire or foam, is used to push any lock control component 5 to the error state limit position, the first component 91 and the second component 92 are automatically kept in the locked state. Thus, even if the user uses an incorrect key to rotate the lock cylinder 2 to move the locking mechanism 4 to the second locking position, the error locking mechanism 7 can be used to keep the first component 91 and the second component 92 in the locked state, thereby improving the security level of the security system.

[0104] Secondly, the present invention provides a server, combined with Figure 1 , Figure 4 and Figure 14 The server includes a first device 91, a second device 92, and a security protection system as described in any of the first aspects. The first device 91 is a housing, and the second device 92 is a housing cover. The housing cover covers the top of the housing.

[0105] When the server is unlocked using the wrong key, and the lower surface of at least one inner rotor 511 reaches the outer wall of the lock cylinder 2, the trigger spring 61 inside the inner rotor 511 releases its compressed elastic force. The pressure block 62 connected to it strikes the metal trigger rod 63, causing the trigger rod 63 to disengage from the elastic catch 64. At this time, the trigger rods 63 on the left and right sides connected to the lock control assembly 51, which has moved to the error state limit position, move to the left and right respectively and contact the magnetic sleeve 71. When the main board 74 detects that a trigger rod 63 is in contact with the magnetic sleeve 71, it triggers the error handling module 81 to issue an alarm and a remote alarm. The alarm sound is the server's own beeping sound; the remote alarm sound is the sound generated by a remote computer, such as a computer in the duty room or security room. At the same time, it also triggers the main board 74 to perform data backup and data destruction operations. The main board 74 controls the data to be backed up first and stored in the cloud disk, and then destroys the backed-up data on the server.

[0106] The current generated by the motherboard 74 flows through two second contact points 13 to the cathodes of the upper battery 721 and the lower battery 722, then to the anodes of the upper battery 721 and the lower battery 722, and finally back to the motherboard 74 through the cables 14 connected to the corresponding second contact points 13, forming a current loop to store power in the upper battery 721 and the lower battery 722. When the server is working normally and the locking mechanism 4 is switched normally using a normal key, i.e., when the locking mechanism 4 is normally switched between the first locking position and the second locking position, the current still flows normally in the above sequence.

[0107] When the locking mechanism 4 is opened by an unconventional operation, i.e., when the locking mechanism 4 releases the lock on the first device 91 and the second device 92, the magnetic sleeve 71 is triggered by the trigger rod 63. The key drives the lock cylinder 2 to rotate clockwise, i.e., the lock cylinder 2 switches from the unlocked state to the unlocked state. During this process, the lock cylinder 2 also drives the magnetic sleeve 71 to rotate clockwise, and the four conductive areas 711 reconnect to the two first contact contacts 12 and the two second contact contacts 13. The position sensor on the main board 74, i.e., the signal converter 742, will detect that the magnetic sleeve 71 has rotated clockwise. The main board 74 will then control the upper battery 721 to discharge. The upper battery 721, through discharge, controls the locking assembly 73 to keep the box and the lid in the locked state.

[0108] It should be noted that in this embodiment, the motherboard 74 continuously monitors the remaining power of the upper battery 721 and the lower battery 722 through two sets of first contact contacts 12 and second contact contacts 13. When the remaining power of the upper battery 721 and / or the lower battery 722 is lower than a certain threshold, the motherboard 74 initiates energy storage for the corresponding upper battery 721 and / or the lower battery 722. This embodiment does not limit the specific circuit structure in the motherboard 74 that controls the charging of the upper battery 721 and / or the lower battery 722, which can be implemented by existing technology.

[0109] The security protection system and server provided in this embodiment of the invention, by setting up a lock control accessory 5, an error triggering mechanism 6, and an error locking mechanism 7, can ensure that the lock control accessory 5 is in its natural state position when no key is inserted into the lock cavity 21; when the correct key is inserted into the lock cavity 21, the lock control accessory 5 is in its correct state position, at which time the key can control the locking mechanism 4 to switch between the first lock control position and the second lock control position, and the error triggering mechanism 6 keeps the first device 91 and the second device 92 in the unlocked state through the error locking mechanism 7; when an incorrect key is inserted into the lock cavity 21, the incorrect key can cause the lock control accessory 5 to... When the device is in the error state limit position, although the key can control the locking mechanism 4 to switch the first device 91 and the second device 92 between the locked and unlocked states, it will also trigger the error triggering mechanism 6 so that the error locking mechanism 7 keeps the first device 91 and the second device 92 in the locked state. This effectively avoids the situation where the wrong key or the use of a non-key structure device attempts to switch the first device 91 and the second device 92 from the locked state to the unlocked state. Thus, when the first device 91 and the second device 92 are used as the server's casing, the security protection level of the server is improved.
