Electronic door lock with a monitoring unit

An electronic door lock comprising:

• a housing having two side plates spaced apart from each other in a left-and-right direction to define a receiving space therebetween, and a lock plate disposed normal to said side plates and interconnecting front sides of said side plates;
• a dead bolt unit disposed in said receiving space, and having a dead bolt which is movable a front-and-rear direction through said lock plate, and a deadbolt transmitting assembly which is linked to move said dead bolt;
• a latch bolt unit disposed in said receiving space, and having a latch bolt which is movable in the front-and-rear direction through said lock plate, a latchbolt transmitting assembly which is linked to move said latch bolt, and a latchbolt spring which is disposed to bias said latch bolt forwardly through said lock plate;
• a lock core unit having a cylinder which is securely disposed on one of said side plates, a core which is rotatably mounted in said cylinder to be operatively actuated by a mechanical key, and a core transmitting assembly which is linked to both said deadbolt transmitting assembly and said latchbolt transmitting assembly and which is actuated by a rotation of said core to move said deadbolt transmitting assembly and said latchbolt transmitting assembly;
• a prying resisting unit disposed in said receiving space, and having a prying resisting member which is movable in the front-and-rear direction through said lock plate, and a prying resisting spring which is disposed to bias said prying resisting member forwardly through said lock plate;
• an operating unit having a swingable linkage assembly which is disposed in said receiving space, which is linked to both said deadbolt transmitting assembly and said latchbolt transmitting assembly, and which is swingable by an operated torque to move said deadbolt transmitting assembly and said latchbolt transmitting assembly, an external actuated member which is disposed in said receiving space and rotatable to provide the operated torque to said swingable linkage assembly, an internal actuated member which is disposed in and rotatable relative to said external actuated member, a clutch pin which is disposed in and movable relative to said external driving member between an engaged position, where said clutch pin is engaged with said internal actuated member so as to allow synchronous rotation of said external actuated member with said internal actuated member, and a disengaged position, where said clutch pin is disengaged from said internal actuated member so as to allow an idle rotation of said internal actuated member relative to said external actuated member, an electric driving assembly which is disposed in said receiving space to operatively actuate movement of said clutch pin between the engaged and disengaged positions, an internal operating handle which has an internal driving section that extends into said receiving space through one of said side plates to be in engagement with and rotate said external actuated member, and an external operating handle which has an external driving section that extends into said receiving space through the other one of said side plates to be in engagement with and rotate said internal actuated member;
• a control unit including a control circuit board which is connected electrically with said electric driving assembly to control operation of said electric driving assembly, and a battery which is disposed to supply power to said control circuit board;
• and
• a monitoring unit including a deadbolt sensor corresponsive to said deadbolt transmitting assembly, a latchbolt sensor corresponsive to said latchbolt transmitting assembly, a prying resisting sensor corresponsive to said prying resisting member, a core sensor corresponsive to said core transmitting assembly, and a security controller connected electrically with said bolt sensor, said latchbolt sensor, said prying resisting sensor and said core sensor to perform a security procedure in accordance with positions of said deadbolt transmitting assembly, said latchbolt transmitting assembly, said prying resisting member and said core transmitting assembly respectively sensed by said deadbolt sensor, said latchbolt sensor, said prying resisting sensor and said core sensor.
