[0019] Embodiment 1

[0020] This embodiment proposes a smart door lock that can identify an identity and monitor the locking status, which is used to solve the problem that when the smart lock is opened by mistake, the door is directly opened and the user cannot get a timely warning.

[0021] A smart door lock capable of identity recognition and monitoring of locking status, the smart door lock being installed at a door frame, the smart door lock comprising a lock body, a lock core, a lock tongue, a lock slot and a handle, the lock core being located in the lock body, the lock tongue being connected to the lock core, a lock slot being provided in the door frame, the lock tongue being movable in the lock slot, a locking area, a waiting area and an unlocking area being provided in the lock slot, the lock core being capable of controlling the lock tongue to move from the locking area to the waiting area, the handle being connected to the lock tongue, and the handle being capable of controlling the lock tongue to move from the waiting area to the unlocking area;

[0022] It also includes a controller, a sensor and a positioning structure, wherein the positioning structure is installed on the lock tongue, the controller is installed in the lock core, the sensor is electrically connected to the controller, and the sensor can monitor the position status of the lock tongue through the positioning structure and feed back the position status information of the lock tongue to the controller.

[0023] It also includes a transmission mechanism, which is installed between the handle and the lock tongue, and the handle drives the lock tongue to move through the transmission mechanism.

[0024] When the smart lock is opened by remote control, the lock tongue of the smart lock will move from the locking area to the waiting area under the control of the lock core. At this time, the door is not opened, and an external person is still required to operate the handle to move the lock tongue from the waiting area to the unlocking area before the door can be opened; at the same time, a sensor and a positioning structure are set in the smart lock. The sensor can monitor the position status of the lock tongue through the positioning structure. When the sensor detects that the lock tongue is in the locking area, it means that the door is locked at this time, preventing the user from leaving the door due to force or negligence when closing the lock; when the smart lock fails and causes the smart lock to be opened by mistake, the lock tongue of the smart lock will only move from the locking area to the waiting area. At this time, when the sensor detects that the lock tongue of the smart lock stays in the waiting area for a period of time, the sensor will feedback the position status information of the lock tongue at this time to the controller, and the user can know that the door is opened by mistake; when the lock tongue moves from the waiting area to the unlocking area, the door is opened at this time, and the sensor will feedback the locking, mis-opening and unlocking information of the smart lock to the controller respectively, so that the user can always grasp the locking status of the smart lock, thereby improving the safety performance of the smart lock.

[0025] Furthermore, the positioning structure is a reflective structure, and the sensor is an optical sensor. When the reflective structure on the lock tongue passes through the optical sensor, the light received by the optical sensor will change, and the optical sensor monitors the position status of the lock tongue by identifying the change in light.
