The following describes in detail the operation of the electronic lock cylinder according to the invention, by way of example.
Unlocking process
The operator carries unlocking equipment to be close to the electronic lock core, the unlocking equipment is connected with the unlocking equipment through the wireless communication module, identity validity is verified, after the identity verification is passed, the built-in battery 150 supplies power to the electronic circuit 141, the electronic circuit 141 supplies power to the gear motor 120, the gear motor 120 rotates to drive the driving gear 131 to rotate, due to the fact that certain pre-pressure exists on the torsion spring 135, the incomplete tooth part 1321 always has the trend of being meshed with the driving gear 131 in the locking state, when the driving gear 131 rotates, the driving gear 131 is meshed with the incomplete tooth part 1321 of the driven gear 132, the driven gear 132 is driven to rotate against the elastic force of the torsion spring 135, after the driven gear 132 rotates by a certain angle, the first protruding part 1322 of the driven gear 132 abuts against the first end of the torsion spring 135, the second end of the torsion spring 135 abuts against the second protruding part 1332 of the unlocking shaft 133, the unlocking shaft 133 is pushed to rotate against the internal resistance of the lockset unlocking mechanism, and the unlocking part 1331 is driven to rotate, and accordingly the lockset is unlocked. When the driven gear 132 rotates to the point that the incomplete tooth portion 1321 is no longer meshed with the driving gear 131, the incomplete tooth portion 1321 always has a tendency of meshing with the driving gear 131 under the elastic force of the torsion spring 135, at this time, the driving gear 131 is in an idle state, the driven gear 132 is basically in a static state, and when a certain condition is met, the electronic circuit 141 does not supply power to the gear motor 120 any more, the driving gear 131 stops rotating, and the unlocking process is ended.
It should be noted that, the electronic lock core has an advantage that, when the unlocking mechanism of the lock cannot be operated due to an external factor, the electronic unlocking operation is performed, the driven gear 132 rotates under the driving of the driving gear 131, and the unlocking portion 1331 cannot rotate due to the limitation of the unlocking mechanism that cannot be operated normally, so that the driven gear 132 cannot drive the unlocking shaft 133 to rotate through the torsion spring 135, but at this time, the torsion spring 135 is stretched, and a torque is generated. When certain conditions are met, the electronic circuit 141 no longer supplies power to the gear motor 120, and the torsion spring 135 remains in a stretched state. At this time, once the external factor that causes the unlocking mechanism of the lockset to fail to act disappears, the elastic force of the torsion spring 135 can be released, and the elastic force of the torsion spring 135 is smaller than the internal resistance of the gear motor 120 and larger than the internal resistance of the unlocking mechanism of the lockset, so that the elastic force of the torsion spring 135 cannot drive the gear motor 120 to rotate reversely, and can drive the unlocking shaft 133 to rotate, thereby driving the unlocking mechanism of the lockset to act, and completing the unlocking process. Therefore, in the electronic lock cylinder provided by the embodiment of the invention, when the unlocking mechanism of the lock is limited after the first electronic unlocking operation, and the unlocking operation can not be completed, the electronic lock cylinder can be unlocked without the need of carrying out the electronic unlocking operation again after the limiting of the unlocking mechanism is released.
Locking working process
The operator carries unlocking equipment to be close to the electronic lock core, be connected with unlocking equipment through wireless communication module, verify the identity legitimacy, the built-in battery 150 supplies power to electronic circuit 141 behind the authentication, electronic circuit 141 supplies power to gear motor 120, gear motor 120 rotates and drives driving gear 131 to rotate in the opposite direction, because torsional spring 135 exists certain precompression, make when the unblock state, incomplete tooth portion 1321 have the trend with driving gear 131 meshing all the time, when driving gear 131 rotates, driving gear 131 meshes with the incomplete tooth portion 1321 of driven gear 132, thereby drive driven gear 132 overcomes the elasticity rotation of torsional spring 135, after driven gear 132 rotates certain angle, driven gear 132's first protruding portion 1322 supports the second end of pressing torsional spring 135, and promote torsional spring 135 rotation, torsional spring 135's first end supports the second protruding portion 1332 of pressing unlocking shaft 133, overcome the internal resistance of tool to unlock mechanism and promote unlocking shaft 133 rotation, and then drive unlocking portion 1331 rotates, thereby the lock is locked. When the driven gear 132 rotates to the point that the incomplete tooth portion 1321 is no longer meshed with the complete tooth portion, the incomplete tooth portion 1321 always has a tendency to mesh with the driving gear 131 under the elastic force of the torsion spring 135, at this time, the driving gear 131 is in an idle state, the driven gear 132 is basically in a stationary state, and when a certain condition is satisfied, the electronic circuit 141 no longer supplies power to the gear motor 120, the driving gear 131 stops rotating, and the locking process is ended.
