[0002] Smart electronic lock is a modern door lock system that uses electronic technology, digital passwords or other methods without traditional physical keys to authorize and manage door lock access. It is different from traditional mechanical locks. Smart electronic locks provide a more convenient, safe and intelligent door lock solution, reducing the dependence on traditional physical keys and adapting to the needs of modern life.

[0003] In the application number "CN216748824U" announced, "A smart electronic lock" solves the problem of low security of existing electronic locks, but the application does not have the function of quick disassembly and quick installation of the smart electronic lock and cannot protect the RFID chip. In practice, the interior of the smart electronic lock is relatively sophisticated. When the smart electronic lock fails, it is usually necessary to remove it for maintenance convenience. However, the smart electronic lock is usually fixed to the door with parts such as screws, which is inconvenient to disassemble and repair. In addition, due to long-term use and frequent opening and closing of the door, the force of closing the door is not well controlled, and the shock of closing the door is transmitted to the smart electronic lock, which can easily damage the RFID chip inside the smart electronic lock. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an RFID-based intelligent electronic lock, which solves the problem that the RFID chip can not be quickly disassembled and installed during maintenance and that frequent door opening can easily damage the RFID chip.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: an RFID-based smart electronic lock, comprising an electronic lock body, a mounting mechanism is provided at the bottom of the electronic lock body, the mounting mechanism comprises a fixed support, two limit fixing mechanisms are provided inside the fixed support, the two limit fixing mechanisms include a toggle plate and a limit box, a locking mechanism is provided at the bottom of the fixed support, a circuit board is provided inside the electronic lock body, and an RFID chip is installed on the top of the circuit board.

[0013] Beneficial Effects

[0014] The utility model provides an RFID-based intelligent electronic lock. Compared with the prior art, it has the following beneficial effects:

[0015] 1. In the utility model, the user fixes the fixed support on the door through the provided installation mechanism, and then the user aligns the two rectangular damping blocks with the inside of the two first grooves respectively, and then inserts the two rectangular damping blocks into the inside of the two first grooves. During the insertion process, the top and bottom ends of the electronic lock body respectively squeeze the two limit blocks. Since the two limit blocks are squeezed, the two squeezed limit blocks squeeze the two damping springs, and then the two limit blocks slide into the inside of the two limit boxes. When the two rectangular damping blocks are inserted into the inside of the first grooves, the two second grooves at the top and bottom ends of the two electronic lock bodies are aligned with the two limit blocks. The positioning block is no longer squeezed by the top and bottom ends of the electronic lock body. At this time, the two limit blocks are supported by the two damping springs, and the two limit blocks are against the two second grooves. At this time, the electronic lock body is fixed, which can achieve the purpose of quickly installing the electronic lock body. Then the user pushes the locking rotating plate so that the locking rotating plate and the locking block are placed in the locking groove at the bottom end of the electronic lock body. Then rotation can strengthen the fixing effect of the electronic lock body. When disassembly is required, the locking rotating plate is rotated in the opposite direction, and then the locking rotating plate is pulled out, and then the two toggle plates are pushed again, so that the toggle plates drive the two limit blocks away from the second grooves. At this time, the electronic lock body can be taken out, so as to achieve the purpose of quick maintenance.

[0016] 2. In the utility model, through the protection mechanism provided, when the user closes the door, the door is engaged with the door frame. When the door is engaged with the door frame and the door contacts the door frame, the door may be impacted and cause vibration, and the vibration is transmitted to the electronic lock body. The vibration is first transmitted to the rubber base pad, which reduces part of the vibration, and then the vibration is transmitted to multiple micro airbags, which offset most of the vibration, and then a small part of the vibration is transmitted to the buffer pad, which offsets the remaining small part of the vibration.
