Electronic door lock with clutch

An electronic door lock with a clutch, comprising an external lock, wherein the external lock comprises:

• a front housing;
• a front knob assembly rotatably inserted into the front housing, wherein a rotation limiting structure is disposed between the front housing and the front knob assembly, and the rotation limiting structure is configured to limit a rotation angle of the front knob assembly relative to the front housing;
• a lock cylinder mounted on the front knob assembly and provided with a tail rack at a tail end, wherein the tail rack is configured to be connected to a lock body and is rotatable relative to the lock cylinder;
• a clutch component that is connected to the tail rack to be capable of rotating together with the tail rack and is rotatable relative to the front knob assembly;
• and
• a motor clutch assembly that is disposed on the front housing and is capable of being electrically driven to limit rotation of the clutch component relative to the front knob assembly,
• wherein the clutch component is provided with convex portions, and the front knob assembly is provided with a convex column in press fit with the convex portions;
• when the electronic door lock is unlocked, the convex portions are located within a rotation range of the convex column;
• or when the electronic door lock is locked, the convex portions are outside the rotation range of the convex column;
• wherein the front knob assembly is rotatable to drive the tail rack for locking without power to the motor clutch assembly and without a key, when the convex portions are within the rotation range of the convex column.
