In the following, the operation of the electromechanical lock cylinder of the present invention will be described in detail.

Unlocking process

With reference to figures 3a and 4 a-4 c the operator carries the unlocking device close to the electromechanical cylinder, the wireless communication module is connected with the unlocking equipment to verify the validity of the identity, and after the identity is verified, the built-in power supply 160 supplies power to the electronic circuit, the electronic circuit supplies power to the reduction motor 120, the reduction motor 120 rotates to drive the driving gear 141 to rotate clockwise (referring to fig. 3a, fig. 3a shows a locked state), the driving gear 141 drives the driven gear 142 to rotate against the elastic force of the torsion spring 145, when the driven gear 142 rotates a certain angle, the first protrusion 1421 of the driven gear 142 presses against the first end of the torsion spring 145, and pushes the torsion spring 145 to rotate, the second end of the torsion spring 145 presses against the second protrusion 1432 of the unlocking shaft 143, and the unlocking shaft 143 is pushed to rotate by overcoming the internal resistance of the lock unlocking mechanism, so as to drive the unlocking part 1431 to rotate, thereby unlocking the lock. Because the limit mechanism 1433 of the unlocking shaft 143 can only abut against the limit portion 1441 of the rotating shaft 144 when the unlocking shaft 143 rotates clockwise, the rotating shaft 144 does not move during the unlocking process, and after the unlocking shaft 143 rotates to the unlocking position, the limit portion 1441 of the rotating shaft 144 rotates to a limit angle in the limit mechanism 1433 of the unlocking shaft 143, and due to the limit of the limit portion 1441 of the rotating shaft 144, the unlocking shaft 143 stops rotating, at this time, if the driving gear 141 continues to drive the driven gear 142 to rotate, the unlocking shaft 143 does not move, the torsion spring 145 will be gradually stretched to store energy, the load current of the motor increases, and the electronic circuit is controlled to stop supplying power to the speed reduction motor by detecting the load current of the motor, so that the unlocking process is completed.

It should be noted that the electromechanical lock cylinder has the following advantages that when the unlocking mechanism of the lock cannot be operated due to external factors, the electronic control unlocking operation is performed, the driven gear 142 is driven by the driving gear 141 to rotate, and the unlocking portion 1431 is restricted by the unlocking mechanism which cannot normally operate, so that the unlocking portion 1431 cannot rotate, and therefore, the driven gear 142 cannot drive the unlocking shaft 143 to rotate through the torsion spring 145, but the torsion spring 145 is stretched, so that a torque is generated. When a certain condition is satisfied, the electronic circuit no longer supplies power to the reduction motor 120, and the torsion spring 145 is still maintained in a stretched state. At this time, once the external factor causing the lock unlocking mechanism to be disabled disappears, the elastic force of the torsion spring 145 can be released, and the elastic force of the torsion spring 145 is smaller than the internal resistance of the deceleration motor 120 and larger than the internal resistance of the lock unlocking mechanism, so that the elastic force of the torsion spring 145 cannot drive the deceleration motor 120 to rotate reversely, and can drive the unlocking shaft 143 to rotate, further drive the lock unlocking mechanism to be enabled to act, and the unlocking process is completed. It can be seen that, the utility model discloses electromechanical lock core carries out automatically controlled unlocking operation the first time after, and the release mechanism of discovery tool to lock is by spacing and can not accomplish under the condition of unlocking operation, after release mechanism's is spacing, need not to carry out automatically controlled unlocking operation again, can the unblock.

Locking operation process

An operator carries the unlocking device to be close to the electromechanical lock cylinder, and is connected with the unlocking device through the wireless communication module to verify the validity of identity, after the identity verification is passed, the built-in power supply 160 supplies power to the electronic circuit, the electronic circuit supplies power to the speed reduction motor 120, the speed reduction motor 120 rotates to drive the driving gear 141 to rotate in the counterclockwise direction (the observation direction is the same as that in fig. 3 a), the driving gear 141 drives the driven gear 142 to rotate, the elastic potential energy of the torsion spring is gradually released and then reversely and gradually stored, after the driven gear 142 rotates for a certain angle, the first protruding part 1421 of the driven gear 142 is pressed against the second end of the torsion spring 145 to push the torsion spring 145 to rotate, the first end of the torsion spring 145 is pressed against the second protruding part 1432 of the unlocking shaft 143 to overcome the internal resistance of the lock unlocking mechanism to push the unlocking shaft 143, thereby locking the lock. Because the limit mechanism 1433 of the unlocking shaft 143 can only abut against the limit portion 1441 of the rotating shaft 144 when the unlocking shaft 143 rotates counterclockwise, the rotating shaft 144 does not move during the unlocking process, and after the unlocking shaft 143 rotates to the unlocking position, the limit portion 1441 of the rotating shaft 144 rotates to a limit angle within the limit mechanism 1433 of the unlocking shaft 143, and due to the limit of the limit portion 1441 of the rotating shaft 144, the unlocking shaft 143 stops rotating, at this time, if the driving gear 141 continues to drive the driven gear 142 to rotate, the unlocking shaft 143 does not move, the torsion spring 145 will be gradually stretched to store energy, the load current of the motor increases, and the electronic circuit is controlled to stop supplying power to the speed reduction motor by detecting the load current of the motor, thereby completing the locking process.

Preferably, the electromechanical lock cylinder is fixed on the lock body through a screw from the inside of the lock body. The lock core can not be disassembled from the outside of the self-locking tool in the fixing mode, and the safety is improved.

The rotating block 221 is rotatably disposed in the lock body, the rotating block 221 is in driving connection with the unlocking portion 1431 of the unlocking shaft 143, the rotating block 221 has an unlocking position and a locking position, the width of the rotating block 221 in the first direction is smaller than that in the second direction, when the first direction of the rotating block 221 faces the locking pin 222, the rotating block 221 is in the unlocking position, and when the second direction of the rotating block 221 faces the locking pin 222, the rotating block 221 is in the locking position.

The latching pin 222 is reciprocally disposed in the lock body, the latching pin 222 has an unlocked position and a locked position, and the latching pin 222 can be switched between the unlocked position and the locked position when the rotating block 221 rotates, so that the lock is switched between the unlocked state and the locked state by the rotation of the rotating block 221. The locking pin 222 has a limiting head, preferably, the limiting head is in the shape of an arc, a V-shape, a trapezoid, or the like; preferably, the latching pins 222 are two.

The latching pin return spring 224 is used to provide a spring force for the latching pin 222 to move to the latched position. In one embodiment, the locking pin return spring 224 is sleeved over the locking pin 222, and a first end of the locking pin return spring 224 abuts against the locking pin 222 and a second end abuts against the lock body.
