Smart home door lock

Abstract

The invention relates to the field of door locks, in particular to a smart home door lock which comprises a main body, a grip component and a protective component. After determining that a fingerprintis correct, a fingerprint pressure sensor arranged on a handle in the grip component can start an electric-hydraulic pusher to push a transmission inserting block on a connecting block to be connected into a transmission slot in a lock pillar in an inserting manner, so that the handle can drive the lock pillar to rotate while rotating; if the fingerprint verification mode is not successfully identified, the handle does not drive the lock pillar to rotate when the handle is rotated, and the handle drives a transmission pillar to rotate along an outer sleeve, so that the safety of the door lockis improved; a U shaped inserting plate arranged in the protective component effectively enables a square spring bolt not to contract; and when a protective plate is poked upwards on the condition ofnot being pressed, the protective plate does not drive a transmission sleeve to move through a transmission inserting rod, so that the protective plate cannot drive the U shaped inserting plate to beseparated from the square spring bolt when the protective plate is poked, and the door cannot be opened.
