This arrangement can avoid the situation in which the driving gear 141 and the driven gear 142 cannot be engaged during the unlocking operation.

Specifically, the torsion of the torsion spring 145 is greater than 0 when the locking mechanism is in the unlocked state. Specifically, referring to fig. 4c, in the locked state, the position of the driving gear 141 is fixed, the tooth of the driving gear 141 is pressed against the outer side of the tooth of the second end of the incomplete tooth 1421 of the driven gear 142 to limit the driven gear 142, the rotating shaft 144 cannot rotate, the limiting mechanism 1433 of the unlocking shaft 143 is in limiting fit with the limiting portion of the rotating shaft 144, so that the unlocking shaft 143 is limited, two ends of the torsion spring 145 are respectively pressed against the first protruding portion 1422 and the second protruding portion 1432, and the distance between two ends of the torsion spring 145 is greater than the distance between two ends of the torsion spring 145 in a natural state, so that the torsion spring 145 has a pre-pressure on the driven gear 142 and the unlocking shaft 143, and the incomplete tooth 1421 of the driven gear 142 tends to be engaged with the driving gear 141. This arrangement can prevent the driving gear 141 and the driven gear 142 from being disengaged during the locking operation.

Electric control module

The power is supplied by the built-in battery, so that the lock cylinder can be applied to occasions without an external power supply, and the use environment of the lock cylinder is expanded. In another embodiment, the power supply module 152 may also be a wireless power supply. Those skilled in the art will appreciate that the electronic circuit may also be powered by an external power source. When the external power supply is used for supplying power, the power supply module 152 is an electrical connection module 152 for electrically connecting the electronic circuit and the external power supply, as shown in fig. 1, the electrical connection module 152 is exposed at a hole formed in the outer wall of the lock cylinder housing 110, and the external power supply can supply power to the electronic circuit through the power supply connection module 152. The external power supply is adopted for supplying power, so that the lock cylinder is simple in structure, the charging and replacement of the battery are not needed, and the manual maintenance cost is reduced. The electromechanical lock core integrates the electric control module 151 and the power supply module 152, the universality of the electromechanical lock core can be improved, and the electromechanical lock core is adaptive to locks with different structures, so that the electric control module 151 and the power supply module 152 do not need to be designed for the locks independently.

The electromechanical lock cylinder further comprises a cover plate, wherein the cover plate is arranged on the outer end face of the lock cylinder shell 110, and internal parts of the electromechanical lock cylinder can be packaged in the lock cylinder shell 110.

It should be noted that, as those skilled in the art can understand, one aspect of the essential spirit of the present invention is to make the driven gear 142 drive the unlocking shaft 143 to rotate by the torsion spring 145, and the abutting or connection of the first protrusion 1422 and the second protrusion 1432 with both ends of the torsion spring 145 is only a preferred embodiment; in addition, the intermittent driving connection between the unlocking shaft 143 and the rotating shaft 144 has various specific modes, and the specific structural forms are difficult to be exhaustive, and the intermittent driving structure of the first protrusion, the second protrusion and the limiting part of the rotating shaft 144 is only one of the specific modes, so that the structure which can drive the unlocking shaft 143 to rotate through the torsion spring 145 by the driven gear 142 and the structure which can drive the intermittent driving connection between the unlocking shaft 143 and the rotating shaft 144 are all within the scope disclosed by the invention.

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

Unlocking process

An operator carries an unlocking device to be close to the electromechanical lock cylinder, the unlocking device is connected with the unlocking device through a wireless communication module, the identity validity is verified, after the identity verification is passed, a built-in battery supplies power to an electronic circuit, the electronic circuit supplies power to the reducing motor 120, the reducing motor 120 rotates to drive the driving gear 141 to rotate, due to certain pre-pressure of the torsion spring 145, when the locking state is carried out, the incomplete tooth part 1421 always has a tendency of being meshed with the driving gear 141, when the driving gear 141 rotates, the driving gear 141 is meshed with the incomplete tooth part 1421 of the driven gear 142, so that the driven gear 142 is driven to overcome the elastic force of the torsion spring 145 to rotate, when the driven gear 142 rotates for a certain angle, the first protruding part 1422 of the driven gear 142 is pressed against the first end of the torsion spring 145 to push the torsion spring 145 to rotate, the second end of the torsion spring 145 is pressed against the second protruding part 1432 of the unlocking shaft, thereby driving the unlocking part 1431 to rotate, and unlocking the lock. When the driven gear 142 rotates to the incomplete tooth 1421 and is not engaged with the driving gear 141 any more, the incomplete tooth 1421 tends to be engaged with the driving gear 141 all the time under the elastic force of the torsion spring 145, at this time, the driving gear 141 is in an idle rotation state, the driven gear 142 is basically in a static state, when a certain condition is met, the electronic circuit does not supply power to the reduction motor 120 any more, the driving gear 141 stops rotating, and the unlocking process is finished.

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. When the driven gear 142 has an incomplete gear structure, the driving gear 141 idles after it rotates at a certain angle, thereby preventing the motor from being locked.

Locking operation process

An operator carries the unlocking device to be close to the electromechanical lock cylinder, the unlocking device is connected with the unlocking device through the wireless communication module, the identity validity is verified, after the identity verification is passed, the built-in battery supplies power to the electronic circuit, the electronic circuit supplies power to the speed reducing motor 120, the speed reducing motor 120 rotates to drive the driving gear 141 to rotate in the opposite direction, due to certain pre-pressure of the torsion spring 145, when the unlocking state is realized, the incomplete tooth part 1421 always has a tendency of being meshed with the driving gear 141, when the driving gear 141 rotates, the driving gear 141 is meshed with the incomplete tooth part 1421 of the driven gear 142, so that the driven gear 142 is driven to rotate by overcoming the elasticity of the torsion spring 145, when the driven gear 142 rotates for a certain angle, the first protruding part 1422 of the driven gear 142 is pressed against the second end of the torsion spring 145 and pushes the torsion spring 145 to rotate, the first end of the, the internal resistance of the lock unlocking mechanism is overcome to push the unlocking shaft 143 to rotate, and then the unlocking part 1431 is driven to rotate, so as to lock the lock. When the driven gear 142 rotates to the incomplete tooth part 1421 and is not engaged with the complete gear tooth part, the incomplete tooth part 1421 tends to be engaged with the driving gear 141 all the time under the elastic force of the torsion spring 145, at this time, the driving gear 141 is in an idle rotation state, the driven gear 142 is basically in a static state, when a certain condition is met, the electronic circuit does not supply power to the reduction motor 120 any more, the driving gear 141 stops rotating, and the locking process is finished.

Working process of emergency unlocking

When the electric unlocking cannot be completed, an operator can insert an emergency unlocking key into the emergency unlocking mechanism 130, rotate the emergency unlocking mechanism 130, further drive the rotating shaft 144 to rotate, the limiting part of the rotating shaft 144 is abutted to the limiting mechanism 1433 of the unlocking shaft 143, so that the rotating shaft 144 rotates to drive the unlocking shaft 143 to rotate, further drive the unlocking part 1431 to rotate, the unlocking operation is completed, the lock is in an unlocking state, and the torsion spring 145 is in a stretching state; the emergency unlocking mechanism 130 is rotated reversely, the rotating shaft 144 rotates relative to the unlocking shaft 143 within the range limited by the limiting mechanism 1433 of the unlocking shaft 143 (because the rotating shaft 144 and the unlocking shaft 143 are connected in an intermittent driving mode, the unlocking shaft 143 is not driven by the rotating shaft 144 at this time), the rotating shaft 144 returns to the initial position, the emergency unlocking key is pulled out, the emergency unlocking process is completed, the unlocking shaft 143 is reset under the driving of the torsion spring 145, the unlocking mechanism 1431 is limited by the unlocking mechanism of the lock and is always in the unlocking position, and the torsion spring 145 is also always in a stretching state.

The locking pin is arranged in the lock body in a reciprocating mode and provided with an unlocking position and a locking position, and when the rotating block rotates, the locking pin can be switched between the unlocking position and the locking position, so that the lock can be switched between the unlocking state and the locking state through rotation of the rotating block. The locking pin is provided with a limiting head, preferably, the limiting head is in an arc shape, a V shape or a trapezoid shape and the like; preferably, the number of the locking pins is two.

The latching pin return spring is used for providing elastic force for the latching pin to move to the latching position. In one embodiment, the locking pin return spring is arranged on the locking pin in a sleeved manner, and a first end of the locking pin return spring abuts against the locking pin and a second end abuts against the lock body.

The locking hook is provided with a locking hook locking groove, a limiting head of the locking pin is in limiting fit with the locking hook locking groove, and the locking hook can be switched between an unlocking position and a locking position.

When the locking hook is in the locking position and the rotating block is in the locking position, the rotating block is stopped on a retreating path of the locking pin, a limiting head of the locking pin is in limiting fit with a locking groove of the locking hook, and the locking hook cannot move; when the locking hook is in the unlocking position, and the rotating block is in the unlocking position, the rotating block no longer plays a stop role for the locking pin, the locking pin can be separated from the locking groove of the locking hook, and the limiting head of the locking pin is no longer in limiting fit with the locking groove of the locking hook.

Preferably, the lock further comprises a latch hook return spring for providing the latch hook with an elastic force to move to the unlocking position. When the limiting head is in an arc shape, a V shape or a trapezoid shape and the like, after unlocking operation, the rotating block rotates to the unlocking position, the locking pin is not stopped, the locking hook moves to the unlocking position under the elastic force action of the locking hook reset spring, the locking pin moves backwards under the pressing of the locking hook, the locking hook is ejected out, unlocking is achieved, and the locking hook reset spring can further keep the lock in the unlocking state.

Those skilled in the art will appreciate that the lock of the present invention is not limited to a padlock, and other types of locks are also possible.

The embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiment. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
