[0002] Existing smart door locks usually use keyless methods such as fingerprints, door cards, passwords, etc. to open for the convenience of users. These opening methods require the built-in battery of the smart door lock to be powered. When the battery is exhausted, the above opening methods will not work, making it impossible for users to open the door.

[0003] For this reason, smart door locks are usually equipped with emergency unlocking methods, which are generally equipped with multi-track blade anti-theft lock cores in the lock. Such lock cores are available in real plug cores and fake plug cores, but users are required to keep the emergency key in case of emergency. However, after people get used to using keyless door opening, they usually do not carry keys with them. Therefore, even if there is a key emergency unlocking method, when emergency door opening is needed, there will be a situation where you have to wait to find the key or the key is not nearby, which brings inconvenience to users.

[0030] Refer to Figure 1-8, an intelligent door lock for keyless emergency unlocking, which includes a panel 10 and a lock core device 30. A lock core face shell 20 is movably arranged on the panel 10. The lock core device 30 includes a lock shell 31, a shifting lever 32, a clutch mechanism 33, a main board 34, an induction antenna and a connecting wire 35. The lock shell 31 is arranged at the rear side of the panel 10. The shifting lever 32 is rotatably arranged on the lock shell 31 or the clutch mechanism 33. The clutch mechanism 33 is arranged on the lock shell 31 and is in transmission connection with the lock core face shell 20. The induction antenna is arranged in the lock core face shell 20. The connecting wire 35 is respectively connected with the main board 34 and the induction antenna, and the main board 34 is electrically connected with the clutch mechanism 33. The main board 34 has a capacitor for storing electricity.

[0031] When the intelligent door lock is in the closed state, the clutch mechanism 33 and the shifting lever 32 are in a disengaged linkage state, and the shifting lever 32 can rotate relative to the clutch mechanism 33. The main board 34 also has a receiving chip and a micro-control chip. The connecting wire 35, the receiving chip and the capacitor are electrically connected in sequence. There is a conversion circuit between the capacitor and the micro-control chip. When the battery power of the intelligent door lock is exhausted and emergency unlocking is required, a smart phone (with NFC function) can be brought close to the lock core face shell 20. The phone sends a radio frequency signal to the induction antenna. The receiving chip will generate an induced voltage and charge the capacitor on the main board 34. After charging, it is converted into a stable voltage through the conversion circuit on the main board 34, and then the clutch mechanism 33 is driven to act through the micro-control chip, linking the clutch mechanism 33 with the shifting lever 32. At this time, rotating the lock core face shell 20 can drive the shifting lever 32 to rotate through the clutch mechanism 33, and the shifting lever 32 drives the lock body to act when rotating, thus realizing door opening. When it is necessary to lock the door, the lock can be confirmed to be locked on the mobile phone APP, and the phone is brought close to the lock core face shell 20 again to charge the capacitor, controlling the clutch mechanism 33 to rotate in the reverse direction and disengage from the shifting lever 32. The lock core face shell 20 is in an idle rotation state, completing the locking operation.

[0032] It should be noted that when the NFC of the mobile phone approaches to charge the capacitor, the communication chip on the main board 34 also communicates with the mobile phone to confirm the identity. After the identity is confirmed, the micro-control chip controls the clutch mechanism 33 to act to ensure safety.

[0033] As described above, in the above solution, on the hardware basis of the existing NFC communication unlocking function, by arranging structures such as a receiving chip, a capacitor, and a conversion circuit on the main board 34, it has the function of a small battery. Using the radio frequency signal emitted by the mobile phone approaching, it can charge the capacitor, thereby providing the electric energy required for the operation of the lock core device 30. From the above operation description, the application of this lock core device 30 in an intelligent door lock can conveniently provide a keyless emergency unlocking method when the intelligent door lock has no power. As long as there is a mobile phone, emergency unlocking can be carried out, avoiding matters such as looking for keys and power banks.
