Claim 7:
8. The electronic door lock of claim 6, wherein the bi-directional overrunning clutch comprises:
the rotatable shaft;
the inner wheel fixedly attached to the rotatable shaft, wherein the inner wheel receives the first torque through rotation of the rotatable shaft;
the outer wheel, wherein the outer wheel receives the second torque from an electrical driving mechanism and rotates around the rotatable shaft; and
the overrunning clutch mechanism, wherein the overrunning clutch mechanism engages with the inner wheel and the outer wheel to pass the first torque and the second torque to the rotatable shaft to operate the locking device on the door, when the outer wheel rotates at the second torque, the inner wheel and the rotatable shaft rotate along with the outer wheel, and when the inner wheel rotates at the first torque, the outer wheel does not rotate along with the inner wheel and the rotatable shaft.
