By using the cooperation of the second clamping block 19 and the second clamping groove 21, the protective bottom plate 20 can be disassembled and installed conveniently and stably, and then the various electrical components inside the smart key can be maintained conveniently and stably.

[0041] As Figure 1 , Figure 4 , Figure 6 and Figure 8 As shown, as a preferred embodiment, on the basis of the above method, further, a second rubber plate 23 is fixedly connected inside the storage frame 22. A rotating shaft 24 is rotatably connected inside the storage frame 22. An installation block 25 is welded and fixed on the rotating shaft 24, and a mechanical key 26 is welded and fixed on the installation block 25. The second rubber plates 23 are symmetrically distributed on both sides inside the storage frame 22, and the two second rubber plates 23 are attached to each other. By using the sealing protection of the second rubber plate 23 and the blocking of the blocking rod 28, the mechanical key 26 can be conveniently stored and sealed, ensuring the convenience and stability of the storage work of the mechanical key 26.

[0042] As Figure 4 , Figure 8 and Figure 9 As shown, as a preferred embodiment, on the basis of the above method, further, a third connecting spring 27 is welded and fixed on the bottom end face of the storage frame 22. The bottom end of the third connecting spring 27 is welded and fixed with a blocking rod 28. The blocking rod 28 is connected in the storage frame 22 in a limiting and sliding manner. A limiting frame 29 is welded and fixed inside the storage frame 22, and a scroll spring 30 is welded and fixed inside the limiting frame 29. The inner end of the scroll spring 30 is welded and fixed on the rotating shaft 24. The blocking rod 28 is connected to the middle part of the bottom of the storage frame 22. The limiting frames 29 are symmetrically distributed on the upper and lower sides of the rotating shaft 24, and the scroll spring 30 corresponds to the limiting frame 29 one by one. By driving the blocking rod 28 to move away from the mechanical key 26, at this time, the scroll spring 30 can drive the mechanical key 26 to automatically rotate to the outside, and then the staff can conveniently perform mechanical unlocking on the safety system control box of the intelligent switch cabinet, ensuring the convenience of the subsequent operations of the staff.

[0043] Specifically, when the intelligent key based on the active safety control system of the switch cabinet is in use: First, after the staff member moves to the intelligent switch cabinet, the staff member can pull up the first clamping blocks 17 on both sides of the top of the protective housing 1 until the first clamping blocks 17 on both sides move out of the first clamping grooves 15 on the protective cover plates 13 on both sides. At this time, under the elastic reset action of the return spring 11, the guide block 12 in the middle part can be pulled to move towards the side of the guide rod 10, and then the protective cover plates 13 on both sides can be driven to move towards the side at the same time. At this time, the first protective groove 2 on the protective housing 1 is opened. Subsequently, the staff member can operate the display screen 9 and each button in the first protective groove 2, and cooperate with the RFID module 8 on the circuit board 4 to identify and verify with the active safety control system of the switch cabinet to confirm the authority of the holder. Subsequently, under the combined action of the data processing and analysis module 6 and the Bluetooth transmission module 7 on the circuit board 4, the system will allow the operation of the active safety control system of the intelligent switch cabinet; And when the staff member needs to open the safety system control box of the intelligent switch cabinet, the staff member only needs to pull down the stop rod 28 at the bottom of the storage frame 22 until the stop rod 28 moves out of the mechanical key 26. At this time, the stop rod 28 will not block the mechanical key 26. Subsequently, under the elastic action of the scroll spring 30 inside the limit frame 29, the mechanical key 26 on the mounting block 25 can be driven to automatically rotate outwards through the rotating shaft 24 and push aside the second rubber plates 23 on both sides. At this time, the mechanical key 26 automatically rotates to the outside, which is convenient for the staff member to use and opens the mechanical lock of the safety system control box, ensuring the convenience of the subsequent operation of the staff member;

[0044] Moreover, after the use of the intelligent key, the staff member only needs to pull down the stop rod 28 at the bottom of the storage frame 22 in advance. At the same time, the staff member can dial the mechanical key 26 into the storage frame 22. Subsequently, the staff member can release the stop rod 28. At this time, under the elastic action of the third connecting spring 27, the stop rod 28 can be driven to automatically move upwards and reset, and block the mechanical key 26. Cooperating with the storage frame 22 and the second rubber plate 23 can conveniently store and seal and protect the mechanical key 26, ensuring the convenience and stability of the storage work of the mechanical key 26;

[0045] Subsequently, the staff can push the protective cover plates 13 on both sides inward. At this time, under the guiding action of the guiding rods 10, the guiding blocks 12 can ensure the stable movement of the protective cover plates 13 until the protective cover plates 13 on both sides move back to their original positions. At this time, the first card slots 15 on the protective cover plates 13 on both sides move to the corresponding first card blocks 17. At this time, under the elastic action of the first connecting spring 16, the first card blocks 17 can be driven to move downward automatically and be engaged into the first card slots 15 on the protective cover plates 13, conveniently completing the clamping and fixing of the protective cover plates 13. At this time, the protective cover plates 13 on both sides cooperate with the corresponding first rubber plates 14 to perform convenient and stable flexible protection work on the display screen 9 and each button on the smart key, improving the carrying safety of the smart key and avoiding the problem of being bumped and damaged during the carrying process of the smart key;

[0046] After the smart key has worked for a long time, the staff can pull the second card block 19 on the protective shell 1 outward until the second card block 19 moves out of the second card slot 21 on the protective bottom plate 20. At this time, the protective bottom plate 20 can be conveniently detached from the second protective groove 3 at the bottom of the protective shell 1. Subsequently, the staff can repair and maintain the electrical components such as the circuit board 4, battery module 5, data processing and analysis module 6, Bluetooth transmission module 7, RFID module 8, etc. inside. Similarly, the staff only needs to pull the second card block 19 outward in advance, and then snap the protective bottom plate 20 into the original position inside the second protective groove 3. At this time, the staff can release the second card block 19. Under the elastic action of the second connecting spring 18, the second card block 19 can be driven to automatically engage into the second card slot 21 on the side of the protective bottom plate 20, completing the clamping and fixing of the protective bottom plate 20, thereby ensuring the stability and safety of the subsequent working state of the smart key.
