[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-6 As shown, a smart door lock based on SIM card recognition includes: a door lock body 1, an operation panel 2 fixedly connected to the upper front of the door lock body 1, a fingerprint reader 3 fixedly installed at the bottom of the operation panel 2, and a front handle 4 rotatably installed at the bottom of the fingerprint reader 3.

[0024] A rear handle 5 is rotatably provided at the lower rear end of the door lock body 1. An installation groove 8 is provided on the upper rear outer wall of the door lock body 1 extending into the interior. A round block 9 is fixedly provided inside the installation groove 8. A slot 10 is provided on the upper surface of the round block 9 extending into the interior.

[0025] The slot 10 has a SIM placement plate 13 inside. Both sides of the SIM placement plate 13 have through holes 14. The inner wall of the through holes 14 is threaded with a fixing screw 11. The inner wall of the mounting groove 8 is threaded with a protective cover 15.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when a SIM card needs to be installed, the fixing screw 11 can be turned with a small screwdriver until it is disengaged from the through hole 14. Then, the SIM card placement plate 13 is moved outward until it is disengaged from the slot 10. The SIM card is then placed in the slot 10, and the SIM card placement plate 13 is reinserted into the slot 10. Finally, the fixing screw 11 is screwed into the through hole 14 to complete the SIM card installation process. Similarly, the SIM card can be removed and installed. The operation is simple and the removal and installation efficiency is high.

[0027] A battery slot 16 is provided at the rear of the middle of the door lock body 1. Multiple battery bodies 12 are installed inside the battery slot 16. A battery cover 6 is rotatably installed at the slot opening of the battery slot 16. Multiple heat dissipation holes 7 are provided through the surface of the battery cover 6. A mounting slot 18 is provided on the outer wall at the lower rear of the door lock body 1 below the rear handle 5. Guide frames 25 are fixedly connected to both sides of the inner wall of the mounting slot 18. A mounting frame 19 is movably installed inside the guide frame 25. An identification module 24 is installed inside the mounting frame 19. A protective cover 23 is movably installed at the slot opening of the mounting slot 18. Mounting blocks 17 are fixedly connected to both sides of the protective cover 23. Fastening screws 22 are threaded through the surface of the mounting blocks 17. Heat dissipation slots 21 are provided through both sides of the protective cover 23. A transparent window 20 is fixedly installed on the surface of the protective cover 23 between the two heat dissipation slots 21.

[0028] Specifically, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, when installing the identification module 24, align the mounting frames 19 on both sides of the identification module 24 with the guide frame 25, then move the mounting frames 19 into the mounting groove 18 until they are fully inserted into the mounting groove 18. Next, cover the opening of the mounting groove 18 with the protective cover 23 and screw the fastening screw 22 into the screw hole on the mounting block 17 to complete the installation of the identification module 24. Similarly, the identification module 24 can be disassembled. By facilitating the disassembly and maintenance of the identification module 24, the maintenance efficiency of the smart door lock can be improved in the later stages.

[0029] In use, when a SIM card needs to be installed, the fixing screw 11 can be rotated with a small screwdriver until it disengages from the through hole 14. Then, the SIM card placement plate 13 is moved outwards until it disengages from the slot 10. The SIM card is then placed in the slot 10, and the SIM card placement plate 13 is reinserted into the slot 10. Finally, the fixing screw 11 is screwed back into the through hole 14, thus completing the SIM card installation process. Similarly, SIM card installation and removal can be performed. The operation is simple and efficient. Secondly, when it is necessary to install the identification module 24, align the mounting frames 19 on both sides of the identification module 24 with the guide frame 25, and then move the mounting frames 19 into the mounting groove 18 until the mounting frames 19 are fully inserted into the mounting groove 18. Then, cover the opening of the mounting groove 18 with the protective cover 23 and screw the fastening screw 22 into the screw hole on the mounting block 17 to complete the installation of the identification module 24. Similarly, the identification module 24 can be disassembled. By facilitating the disassembly and maintenance of the identification module 24, the maintenance efficiency of the smart door lock can be improved in the later stages.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
