The high-safety intelligent electronic lock provided by the embodiment of the invention has the working principle described as follows:

when a control circuit in the electronic lock assembly is normal and the electronic lock assembly does not acquire legal electronic unlocking information such as fingerprints, Bluetooth signals, RF signals and the like, the intelligent electronic lock is in a locked state at the moment, the motor 21 does not work, the baffle is positioned outside an area between the cross bolt 12 and the fixed cylinder 44, and the lock pin 23 is not inserted into the lock pin hole 452 of the rotating cylinder 45; at this time, the rotating column 45 is not associated with the fixed column 44, and when the handle 42 is rotated, the rotating column 45 is not driven to rotate, so that the intelligent electronic lock cannot be unlocked;

when the electronic lock assembly acquires legal electronic unlocking information such as fingerprints, Bluetooth signals, RF signals and the like, the motor 21 works to drive the concave-convex stop block wheel 22 to rotate, and the lock pin 23 is driven to be inserted into the lock pin hole 452 of the rotating column 45, so that the rotating column 45 is associated with the fixed column barrel 44; at the moment, the rotating handle 42 can drive the rotating column to rotate together, so that the intelligent electronic lock is unlocked; preferably, by setting a program in the single chip microcomputer in advance, the motor 21 works again after a certain time to drive the concave-convex block wheel 22 to rotate reversely, and the lock pin 23 is driven to be separated from the lock pin hole 452 of the rotating column 45, so that the intelligent electronic lock is restored to the locking state;

during the normal operation of the control circuit in the electronic lock assembly, if the mechanical lock detection sensor 31 detects that someone tries to unlock the lock through the mechanical lock assembly, the control motor 21 operates to drive the concave-convex block wheel 22 to rotate, so that the blocking plate part moves between the cross bolt 12 and the fixed cylinder 44, and the lock pin 23 is not inserted into the lock pin hole 452 of the rotating cylinder 45; at this time, under the action of the baffle plate portion, even if the mechanical lock 13 is unlocked through a password or a key, the cross bolt 12 cannot be moved to the fixed cylinder 44, the protrusion 121 at the transverse end of the cross bolt 12 cannot be inserted into the top grooves 441 of the rotating column 45 and the fixed cylinder 44 so that the rotating column 45 is associated with the fixed cylinder 44, that is, the intelligent electronic lock cannot be unlocked through the mechanical lock assembly, and the mechanical lock assembly is in a failure state; preferably, by setting a program in the single chip microcomputer in advance, the motor 21 works again after a certain time to drive the concave-convex block wheel 22 to rotate reversely, and the driving block part rotates back to a position outside the area between the cross bolt 12 and the fixed cylinder 44, so that the mechanical lock assembly is separated from the failure state; the specific time when the mechanical lock assembly is in the failure state can be set according to the requirement; it should be noted that, a failure state in which the mechanical lock assembly is not enabled may also be set, that is, when the mechanical lock detection sensor 31 detects that someone tries to unlock the lock assembly through the mechanical lock assembly, the motor 21 is no longer controlled to operate to drive the concave-convex block wheel 22 to operate.

When the control circuit in the electronic lock assembly is abnormal (such as power failure) or is set to be in a failure state of not starting the mechanical lock assembly, the mechanical lock detection sensor 31 is not triggered any more by unlocking the mechanical lock 13 through the password or the key, namely the motor 21 does not work, so that the mechanical lock assembly enters the failure state; at this time, the baffle part is always positioned outside the area between the cross bolt 12 and the fixed cylinder 44, after the mechanical lock 13 is unlocked through a password or a key, the cross bolt 12 can move towards the fixed cylinder 44 by pressing the key 11, so that the transverse end protrusion 121 of the cross bolt 12 is inserted into the top grooves 441 of the rotating column 45 and the fixed cylinder 44, and the rotating column 45 is associated with the fixed cylinder 44; at this time, the rotating handle 42 can drive the rotating column to rotate, thereby realizing unlocking.

Although terms such as housing, handle, mounting chamber, stationary barrel, rotating post, key, cross latch, control circuit board, spring, metal stiffener, groove, guide hole, latch hole, cross end protrusion, guide bar, etc. are used more often herein, the possibility of using other terms is not excluded. These terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed as being without limitation to any additional limitations that may be imposed by the spirit of the present invention.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
