DETAILED DESCRIPTION

[0036] To make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0037] In addition, the term "and / or" in this paper is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can mean that there are three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0038] As Figures 1 to 11 As shown in the utility model provides a kind of for locomotive key management device. The key management device includes first storage cabinet 1, first storage cabinet 1 is equipped with first partition plate 11 and second partition plate 12. First partition plate 11 and second partition plate 12 divide the inside of first storage cabinet 1 into multiple storage cavities 13, and each storage cavity 13 is used to store a locomotive key.

[0039] The front of each storage cavity 13 is provided with an openable and closable door 2, which is connected to the cabinet body of the storage cavity 13 through a hinge, so that it can be easily opened and closed. In order to ensure the safe storage of the locomotive key, the inner side of the door 2 near one end of the storage cavity 13 is provided with a locking mechanism 3, which is used to lock the door 2, so that the door 2 cannot be opened in the unlocked state, thereby effectively preventing the loss or unauthorized use of the key.

[0040] In this embodiment, the first partition plate 11 is also connected with a baffle 14, which is used to further limit the space of the storage cavity 13, and ensure that the keys in each storage cavity 13 are stored independently and do not interfere with each other. At the same time, a label sticking place 22 is provided on the outer side of the door 2, which is used to stick a display label. The label can mark the corresponding locomotive information in the storage cavity 13, which is convenient for the staff to quickly identify and locate the required locomotive key.

[0041] As shown in Figure 1 , Figure 2 and Figure 13 , the first partition plate 11 and the second partition plate 12 divide the inside of the first storage cabinet 1 into 10 independent storage cavities 13. Each storage cavity 13 is designed to store one locomotive key. When the locomotive key needs to be collected, the staff first needs to unlock the locking mechanism 3 of the corresponding storage cavity 13. After the locking mechanism 3 is unlocked, the locking state of the door 2 is released, and the staff can open the door 2 and easily take out the required locomotive key.

[0042] In the operation of storing the key, the staff first opens the corresponding door 2 and stores the key in the designated storage cavity 13. Then, the door 2 is closed, and the locking mechanism 3 automatically locks the door 2, thereby ensuring the safe closing of the storage cavity 13 and preventing the key from being accidentally taken out or lost.

[0043] The key management device not only simplifies the access process of the locomotive key, but also improves the security and efficiency of key management. The label sticking place 22 on the door 2 makes the key stored in each storage cavity 13 correspond to the corresponding locomotive information one by one, avoiding misoperation caused by key confusion. At the same time, the automatic locking function of the locking mechanism 3 reduces the possibility of human operation error, further improving the reliability of management. Compared with the existing "issuance and recovery of locomotive keys mainly depends on manual operation, and usually adopts paper account management method" management method, first, through the reasonable design of the first storage cabinet 1, the first partition plate 11, the second partition plate 12 and the locking mechanism 3, the orderly storage of the locomotive key is realized, avoiding the problems of wrong taking and missing taking in manual operation, and reducing human errors in management. Second, the label sticking place 22 on the door 2 makes each key correspond to the corresponding locomotive information clearly, which is convenient for quick searching and taking, and improves the efficiency of key management. Most importantly, the automatic locking function of the locking mechanism 3 further ensures the safety of key storage, effectively avoids the loss or unauthorized use of keys, and improves the security and standardization of locomotive key management.

[0044] In the key management device, the design and operation of the locking mechanism 3 is an important part to ensure the safe storage and management of the locomotive key, and the locking mechanism 3 includes a locking piece 31, a locking rod 32, a guide shaft 33, a spring 34, a mounting seat 35 and a reciprocating mechanism 36. Among them, the locking piece 31 is fixedly connected with the locking rod 32, and the mounting seat 35 is fixed on one side of the door 2 close to the storage cavity 13. The guide shaft 33 is fixedly connected with the mounting seat 35, and the guide shaft 33 extends into the sliding groove on the locking rod 32, and the sliding groove is in sliding connection with the guide shaft 33, thereby providing guidance for the movement of the locking rod 32. The spring 34 is sleeved on the guide shaft 33 and located between the locking rod 32 and the mounting seat 35, and provides a spring force to push the locking rod 32 away from the mounting seat 35.

[0045] The front end of the locking piece 31 is provided with a guide slope 311, so that when the door 2 is closed, the locking piece 31 can smoothly pass through the baffle 14. The locking rod 32 is fixedly connected with a push plate 321, and the push plate 321 is in contact with the reciprocating mechanism 36, which is used to drive the movement of the locking rod 32 through the movement of the reciprocating mechanism 36.

[0046] In the normal state (i.e. when the reciprocating mechanism 36 is in the initial state and is not started), the spring 34 provides a spring force to the locking rod 32, and the locking rod 32 drives the locking piece 31 to extend away from the side of the door 2 hinged to the first storage cabinet 1. At this time, the locking piece 31 is located on the side of the baffle 14 close to the storage cavity 13, and through the cooperation of the locking piece 31 and the baffle 14, the door 2 cannot be opened in the unlocked state, thereby effectively preventing the loss or unauthorized use of the key.

[0047] When the door 2 needs to be opened to take out the locomotive key, the reciprocating mechanism 36 is first started, and the reciprocating mechanism 36 starts to move in the first direction and drives the lock rod 32 to move towards the mounting seat 35 through the push plate 321. In this process, the guide shaft 33 plays a stable guiding role for the movement of the lock rod 32, and the spring 34 is gradually compressed. When the lock rod 32 drives the locking part 31 to gradually move away from the baffle 14, the locking effect of the locking mechanism 3 on the door 2 is removed, and at this time the door 2 can be opened.

[0048] After the key is taken out, the reciprocating mechanism 36 moves in the opposite second direction, gradually separates from the push plate 321, and finally returns to the initial state. With the reset of the reciprocating mechanism 36, the restoring force of the spring 34 drives the lock rod 32 to move away from the mounting seat 35, and the lock rod 32 drives the locking part 31 to return to the normal state.

[0049] When the staff completes the taking out or storing of the locomotive key, the door 2 is closed again. At this time, the guide inclined surface 311 of the locking part 31 is in contact with the baffle 14, and under the action of the guide inclined surface 311, the locking part 31 is pressed and drives the lock rod 32 to move slightly towards the mounting seat 35. When the locking part 31 successfully passes the baffle 14 and returns to the side of the baffle 14 close to the storage cavity 13, the restoring force of the spring 34 pushes the locking part 31 back to the normal state, and through the cooperation of the locking part 31 and the baffle 14 again, the door 2 is automatically locked. Through the above structure design and operation process, the locking mechanism 3 of the key management device can realize the automatic locking function of the locomotive key storage cabinet, ensure the safety and reliability of the key in the storage and use process, and the operation is simple, which improves the safety and efficiency of the key management.

[0050] In the key management device, the locking mechanism 3 realizes the automatic locking and unlocking of the door 2 through the reciprocating mechanism 36. The reciprocating mechanism 36 comprises two linear bearings 361, a push rod 362, a connecting piece 363, a transmission arm 364, a driving arm 365, a driving rod 366 and a motor 367. The two linear bearings 361 are fixedly installed on one side of the door 2 close to the storage cavity 13, and are used for providing guiding and limiting effects for the linear motion of the push rod 362, and ensuring the stability and smoothness of the push rod 362 in the running process.

[0051] The push rod 362 passes through two linear bearings 361 and is in sliding connection with the linear bearings 361, so that the push rod 362 can move smoothly along a set track under the guidance of the linear bearings 361. One end of a transmission arm 364 is hingedly connected to a side of the door 2 close to the storage cavity 13, and the other end is connected with a shaft body 3641. The transmission arm 364 is provided with a transmission groove 3642 for guiding the movement of a driving rod 366. A connecting piece 363 is fixedly connected to the push rod 362 and extends out two limiting plates 3631, and the shaft body 3641 is located in a sliding space between the two limiting plates 3631, so that the transmission arm 364 can drive the reciprocating movement of the push rod 362 through the connecting piece 363.

[0052] One end of a driving arm 365 is connected with the driving rod 366, and the driving rod 366 extends into the transmission groove 3642. The other end of the driving arm 365 is connected to an output end of a motor 367. By starting the motor 367, the motor 367 drives the driving arm 365 to rotate, thereby driving the driving rod 366 to perform a circular motion. When the driving rod 366 performs a circular motion, the driving arm 364 is driven to swing relative to the hinged point thereof through the transmission groove 3642. With the swinging of the transmission arm 364, the push rod 362 performs reciprocating linear motion under the guidance of the linear bearings 361.

[0053] When the push rod 362 moves in a first direction, the push rod 362 drives the push plate 321 to move in a direction close to the mounting seat 35, thereby overcoming the elastic force of the spring 34 and gradually releasing the locking relationship between the locking piece 31 and the baffle 14, so as to unlock the door 2. When the push rod 362 moves in a second direction, the push rod 362 gradually moves away from the push plate 321, so that the locking rod 32 returns to the initial position under the action of the spring 34, and the locking rod 32 drives the locking piece 31 to return to the normal state, so as to automatically lock the door 2. Through the above structure design, the reciprocating mechanism 36 can realize the accurate reciprocating movement of the push rod 362, thereby controlling the movement of the locking rod 32, and achieving the unlocking and automatic locking of the door 2.

[0054] Specifically, the locking piece 31 and the locking rod 32 are in an integrated structure. The integrated structure design helps to improve the overall strength and stability of the locking mechanism 3, simplifies the assembly process, reduces the number of parts, and thereby reduces the failure rate and maintenance cost.

[0055] In the key management device, in order to cope with the possible failure of the reciprocating mechanism 36 or the controller thereof, which leads to the failure of unlocking the door 2, the locking mechanism 3 further comprises an emergency unlocking assembly 37. The emergency unlocking assembly 37 ensures that when the electrical system fails, the door 2 can still be safely unlocked by mechanical means, and the use of the locomotive key is not affected.

[0056] Specifically, the emergency unlocking assembly 37 includes a connecting shaft 371 and a gear 372 sleeved on the connecting shaft 371. The gear 372 is fixedly connected with the connecting shaft 371, and the connecting shaft 371 is rotatably connected with the door 2. The connecting shaft 371 is provided with a slot 373 for inserting a mechanical key for manual operation. The transmission arm 364 is provided with a clamping tooth 3643 matched with the gear 372, and the clamping tooth 3643 is in meshing connection with the gear 372.

[0057] When the reciprocating mechanism 36 or its controller fails, causing the door 2 to be unable to be normally unlocked, the operator can insert the mechanical key into the slot 373 on the connecting shaft 371. By rotating the mechanical key, the mechanical key drives the connecting shaft 371 to rotate, and then drives the gear 372 to rotate. The rotation of the gear 372 is transmitted to the transmission arm 364 through the clamping tooth 3643, and drives the lock rod 32 to move to the side close to the mounting seat 35. With the movement of the lock rod 32, the locking piece 31 gradually separates from the baffle 14, and the locking state of the door 2 is released. At this time, the operator can manually open the door 2 to take out the locomotive key in the storage cavity 13.

[0058] After using the emergency unlocking function, the operator pulls out the mechanical key, or cancels the rotating force applied to the mechanical key. At this time, the restoring force of the spring 34 drives the lock rod 32 to move away from the mounting seat 35, and the lock rod 32 drives the locking piece 31 to return to the normal locking state. After that, when the door 2 is closed, the locking piece 31 of the locking mechanism 3 cooperates with the baffle 14 again, so that the door 2 cannot be opened in the unlocked state, thereby continuing to realize the safe storage and management of the locomotive key.

[0059] In the embodiment, the mechanical key can be a plug matched with the slot 373, which can be made of metal or other solid materials. The shape of the slot 373 is designed according to the actual use and needs. The embodiment does not limit the specific shape of the slot 373 and the mechanical key, but ensures that the mechanical key can be stably inserted into the slot 373 and smoothly drive the connecting shaft 371 to rotate.

[0060] By adding the emergency unlocking assembly 37, the utility model provides a multiple protection mechanism, which ensures that the door 2 can still be unlocked through a simple and reliable mechanical method when the electrical or control system fails. This design further enhances the safety and reliability of the key management device, and is particularly suitable for occasions with high safety and high availability requirements.

[0061] Specifically, the key management device further comprises a bent plate 4 arranged on the side of the sealing door 2 close to the storage cavity 13, and the bent plate 4 is provided with a notch 41 through which the locking member 31 passes. The bent plate 4 is used to protect the structure of the side of the sealing door 2 close to the storage cavity 13, and the notch 41 is arranged to ensure that the locking member 31 can extend out of the bent plate 4.

[0062] In order to further enhance the structure protection performance of the key management device, the utility model also designs a bent plate 4. The bent plate 4 is installed on the side of the sealing door 2 close to the storage cavity 13, and is used to provide additional protection to the structure of the side, while ensuring the normal operation of the locking member 31.

[0063] Specifically, the bent plate 4 is fixedly arranged on the inner side of the sealing door 2 close to the storage cavity 13. The bent plate 4 is provided with a notch 41, and the shape of the notch 41 is matched with the locking member 31, so that the locking member 31 can smoothly pass through the notch 41, extend out of the bent plate 4 when the sealing door 2 is closed, and cooperate with the baffle 14 to realize the locking function of the sealing door 2. The arrangement of the notch 41 ensures that the locking member 31 can freely extend and retract without being hindered by the bent plate 4, so that the normal function of the locking member 31 is not affected. The main function of the bent plate 4 is to provide protection for the locking mechanism 3 on the side of the sealing door 2 close to the storage cavity 13, which can effectively reduce the influence of external force or accidental collision on the locking mechanism 3 and prolong the service life of the device. Meanwhile, the motor 367 is fixedly connected with the bent plate 4.

[0064] When the sealing door 2 is closed, the locking member 31 extends out of the bent plate 4 through the notch 41 and enters the side of the baffle 14 close to the storage cavity 13 to complete the locking of the sealing door 2. In the unlocking process, the locking member 31 is gradually retracted under the driving of the lock rod 32 and returns to the protection range of the bent plate 4 through the notch 41, without affecting the normal opening of the sealing door 2 and the taking of the key. By introducing the design of the bent plate 4, the utility model not only improves the overall protection performance of the key management device, but also effectively protects the key parts in structure. The application of the bent plate 4, especially in the interaction area of the sealing door 2 and the locking member 31, ensures the reliability and stability of the device in long-term use, and further improves the safety and durability of the device.

[0065] In the key management device of the utility model, in order to further enhance the locking effect of the sealing door 2 and ensure the safety of the sealing door 2 in the closed state, a lock block 5 is specially arranged. The lock block 5 is fixedly installed on the side of the baffle 14 close to the storage cavity 13 and is used in cooperation with the locking member 31 to realize the stable locking of the sealing door 2.

[0066] Specifically, the baffle 14 is provided with a locking block 5 near one side of the storage cavity 13. When the door 2 is in the closed state, the locking piece 31 extends through the gap 41 and is in contact with the locking block 5. The locking block 5 is arranged such that the locking piece 31 can form a firm engagement structure with the locking block 5 when locked, thereby further enhancing the locking strength of the door 2 and ensuring that the door 2 cannot be forcibly opened without being unlocked.

[0067] In order to further improve the convenience and operation experience of the key management device, the utility model adds an elastic assembly 6 to the design of the door 2 to realize the automatic pop-up function of the door 2. The elastic assembly 6 can quickly pop up the door 2 through the action of the torsion spring 63 after the locking mechanism 3 is unlocked, which is convenient for the operator to take the key.

[0068] Specifically, the elastic assembly 6 includes a trigger plate 61, a pin shaft 62 and a torsion spring 63. The door 2 is provided with a mounting groove 21 for mounting the elastic assembly 6. The pin shaft 62 is mounted in the mounting groove 21, and the trigger plate 61 is rotationally connected to the door 2 through the pin shaft 62. One end of the torsion spring 63 is fixedly connected to the inner wall of the mounting groove 21, and the other end is connected to the trigger plate 61 to provide a rotating force of the trigger plate 61 relative to the pin shaft 62.

[0069] When the door 2 is in the closed state, the distal end of the trigger plate 61 is in contact with the second partition plate 12, causing the torsion spring 63 to be compressed. At this time, the trigger plate 61 is in the mounting groove 21 and does not affect the appearance and operation of the door 2.

[0070] When the locking mechanism 3 unlocks the door 2, the locking piece 31 is separated from the locking block 5, and the door 2 is unlocked. At this moment, the restoring force of the torsion spring 63 drives the trigger plate 61 to rotate around the pin shaft 62, and the end of the trigger plate 61 away from the pin shaft 62 pops out of the mounting groove 21, thereby pushing the door 2 to slightly pop up a distance. This pop-up action provides convenience for the operator, so that the door 2 can be more easily opened completely, reducing the force required to open the door 2.

[0071] When the door 2 is closed again, the distal end of the trigger plate 61 will again contact the second partition plate 12, pushing the trigger plate 61 to rotate relative to the pin shaft 62, causing the torsion spring 63 to be compressed again. At this time, the trigger plate 61 is retracted into the mounting groove 21, ready for the next use.

[0072] By integrating the elastic assembly 6 in the door 2, the utility model effectively improves the user experience of the key management device. The automatic pop-up function of the door 2 makes the operation smoother, especially in a frequently operated environment, which can significantly reduce the difficulty of opening the door 2 and improve the operation efficiency. At the same time, the design of the elastic assembly 6 is simple and reliable, ensuring the stability and durability in long-term use.

[0073] In order to increase the storage capacity and functional expansibility of the key management device, the utility model further includes a second storage cabinet 8. The second storage cabinet 8 is used as a basic structure to support and expand the storage space, and can be closely combined with the first storage cabinet 1 to form an integrated key management system.

[0074] Specifically, the first storage cabinet 1 is arranged on the upper surface of the second storage cabinet 8. The second storage cabinet 8 provides stable support through reasonable structural design and increases the overall height of the device, which is convenient for the operator to use. In addition, the inside of the second storage cabinet 8 can also be divided and utilized according to actual needs to store other related items such as backup keys, management record files, etc., further improving the convenience of management.

[0075] The combined design of the first storage cabinet 1 and the second storage cabinet 8 makes the key management device more flexible and expandable. The operator can flexibly configure the functions of the first storage cabinet 1 and the second storage cabinet 8 according to specific management needs to achieve comprehensive management of various items.

[0076] In order to further improve the security and intelligent management level of the key management device, the utility model also introduces a face recognition device 7. The face recognition device 7 is used to ensure that only authorized personnel can operate the key management device through biometric technology, thereby further improving the security of locomotive key management.

[0077] Specifically, the face recognition device 7 includes a display screen 71, a processor 72, a camera 73 and a memory 74. The camera 73 is installed at an appropriate position of the key management device for shooting the face image of the operator. The camera 73 is connected with the processor 72 to transmit the shot face image to the processor 72 for analysis and processing.

[0078] The processor 72 is the core part of the face recognition device 7, responsible for processing the image data transmitted from the camera 73. The processor 72 is connected with the display screen 71, and the display screen 71 is used to display the picture shot by the camera 73 in real time, so that the operator can confirm whether the image is correctly captured through the display screen 71.

[0079] The memory 74 is connected with the processor 72 and is used to store the pre-recorded face information. The authorized face information stored in the memory 74 can include the face data of multiple authorized personnel. When the operator stands in front of the camera 73, the face image captured by the camera 73 will be compared with the face information stored in the memory 74.

[0080] If the comparison is successful, the processor 72 confirms that the operator has the permission to open the specific storage cavity 13.

[0081] Once the authority is confirmed, the processor 72 will send a control signal to the motor 367. The motor 367, as the power source of the locking mechanism 3, starts to operate after receiving the signal from the processor 72, driving the reciprocating mechanism 36 to move. The reciprocating mechanism 36, through a series of mechanical transmission components (such as the push rod 362, the transmission arm 364, etc.), finally pushes the locking rod 32 to move towards the mounting seat 35.

[0082] During the movement of the locking rod 32, the locking piece 31 gradually moves away from the position of the baffle 14 or the locking block 5, thereby releasing the locked state of the door 2. When the locking piece 31 completely moves away from the locking position, the door 2 is unlocked, and the operator can easily open the door 2 to take or store the locomotive key in the storage cavity 13. If the comparison result does not match, the locking mechanism 3 remains in the locked state, and the door 2 cannot be opened, thereby effectively preventing unauthorized personnel from operating.

[0083] By introducing the face recognition device 7, the safety performance of the key management device is further improved, and it is ensured that only authorized personnel can operate the device. The application of this biometric technology greatly reduces the security risks caused by human negligence or improper operation in traditional key management. At the same time, the use of the face recognition device 7 also simplifies the operation process, avoids the cumbersome manual input or card recognition process, and provides a more convenient user experience.

[0084] In the key management device of the utility model, the face recognition device 7 is not only used to verify the identity of the operator, but also further optimizes the accuracy of key management. Specifically, the face information corresponds to the locomotive keys in different storage cavities 13, realizing personalized authorization management, ensuring that each operator can only access the storage cavity 13 matching the authorized information, and preventing the misappropriation of keys.

[0085] When the operator performs identity verification through the face recognition device 7, the processor 72 will retrieve the corresponding authorization data from the memory 74 according to the recognized face information. The face information of each operator is bound to a specific storage cavity 13, which means that after successful identity verification, the processor 72 will automatically identify the specific storage cavity 13 that the operator is authorized to access, and control the locking mechanism 3 to only unlock the corresponding door 2.

[0086] For example, the authorization information of a certain operator only corresponds to the keys of a certain train, and the processor 72 will ensure that only the storage cavity 13 storing the keys of the train is unlocked, while the doors 2 of other storage cavities 13 remain locked. This design not only improves the security of management, but also effectively prevents the risk of taking the wrong keys due to operator's misoperation.

[0087] The face information and the corresponding mechanism of the key in the storage cavity 13 make the key management device have high security and accuracy, and is suitable for scenes that need strict management and control. Through this precise authorization management, each key can be properly managed to ensure the safe storage and use of the motorcycle key.

[0088] The processor 72 works as follows: when the operator stands in front of the camera 73, the camera 73 captures the face image of the operator and transmits the image data to the processor 72. The processor 72 first pre-processes the image, including image sharpness adjustment, background filtering, face feature point extraction, etc. The processor 72 compares the pre-processed face feature data with the authorized face information stored in the memory 74. The comparison algorithm is usually based on existing face recognition technology, such as convolutional neural network (CNN) in deep learning, which can accurately match face features. When the processor 72 confirms that the face information of the current operator matches the authorized information in the memory 74, it identifies the storage cavity 13 that the operator is authorized to access according to the corresponding face information. Then, the processor 72 sends an unlock signal to the locking mechanism 3 to control the door 2 of the corresponding storage cavity 13 to unlock. If the comparison fails, the processor 72 keeps the locking mechanism 3 in the locked state and refuses access. The processor 72 can also record the time of each operation, face recognition result, accessed storage cavity 13, etc. These data can be stored in the memory 74 for subsequent query and management. The processor 72 in the present application can use existing embedded microprocessors or single-chip microcomputers.

[0089] In the key management device of the present application, the design and application of the face recognition device 7 are based on the above-mentioned mature face recognition technology. The device includes a camera 73, a processor 72, a display screen 71 and a memory 74, etc. hardware components, combined with existing face recognition algorithms, to realize the identity verification of the operator. Specifically, the camera 73 is used to capture the face image of the operator, the processor 72 processes and compares the image, the memory 74 stores the authorized face information, and the display screen 71 is used to feedback the image capture situation and the recognition result.

[0090] This application form is a direct extension of the existing technology and has been adopted in many fields. For example, existing access control systems, face payment systems, etc. adopt similar technical architecture. Therefore, the application of the face recognition device 7 in the present application also belongs to the result directly realized by the skilled person in the art according to the existing technology. In summary, the working principle, specific structure and use method of the face recognition device 7 and the processor 72 are well known to the skilled person in the art, and will not be described in detail here.

[0091] The specific embodiments described above do not constitute a limitation on the protection scope of the present application. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
