This utility model relates to the field of door lock technology and discloses an intelligent door lock. The intelligent door lock includes a lock body, an electrical device, and an emergency power generation device. The electrical device is installed on the lock body. The emergency power generation device includes a
magnet, a
metal component, an emergency
power storage module, and a drive module. The
magnet is installed on the lock body; the
metal component is located in the
magnetic field of the
magnet; the emergency
power storage module is installed on the lock body; the input end of the emergency
power storage module is electrically connected to the
metal component; the output end of the emergency power storage module is electrically connected to the electrical device; the drive module is installed on the lock body; the drive module is connected to the metal component and is used to drive the metal component to reciprocate along a first direction, so that the metal component charges the emergency power storage module; the first direction is not parallel to the direction of the
magnetic field lines of the magnet. The emergency power storage module can provide a stable current to the electrical device, improving the stability and reliability of the power supply, and solving the problem of poor reliability of emergency unlocking schemes in existing intelligent door locks.
