In order to solve the problem that electromechanical lock core security performance is poor among the prior art, this application provides a lock core, tool to lock and key.

Wherein, the tool to lock is provided with holds the chamber, holds the intracavity and installs as following lock core.

As shown in fig. 1 to 19, the key of the present application is used to unlock a key cylinder described below.

The key 70 includes a key body 73, an unlocking section 71, and a wireless power supply module 72.

The lock cylinder in this application includes a housing 10, a cylinder assembly 20, a mechanical latch assembly 30, an electronic latch assembly 40, a lock assembly 50, and a lock knob 60. At least one part of the lock core assembly 20 is arranged in the shell 10, the lock core assembly 20 is provided with an axial hole 21 for the unlocking section 71 of the key 70 to penetrate, and the lock core assembly 20 can rotate relative to the shell 10; the mechanical locking assembly 30 is movably arranged between the shell 10 and the lock cylinder assembly 20, and the mechanical locking assembly 30 has an unlocking position and a locking position; at least one part of the electronic locking assembly 40 is arranged inside the lock cylinder assembly 20, and the electronic locking assembly 40 can lock and unlock the mechanical locking assembly 30; the locking assembly 50 is arranged between the shell 10 and the lock cylinder assembly 20, and the locking assembly 50 can lock and unlock the electronic locking assembly 40; when the mechanical locking assembly 30 is in the locking position, the unlocking section 71 is inserted into the axial hole 21, after the unlocking section 71 is inserted in place, the unlocking section 71 drives the locking assembly 50 to unlock the electronic locking assembly 40, the wireless power supply module 72 of the key 70 is induced with the electronic locking assembly 40, so that the electronic locking assembly 40 unlocks the mechanical locking assembly 30, and the mechanical locking assembly 30 unlocks the housing 10 and the cylinder assembly 20 under the rotation of the key 70, so that the cylinder assembly 20 can rotate relative to the housing 10; the lock knob 60 is connected to the cylinder assembly 20 and disposed at an end of the cylinder assembly 20 opposite to the end into which the key 70 is inserted, and when the cylinder assembly 20 rotates relative to the housing 10, the lock knob 60 can rotate together with the cylinder assembly 20.

With the lock cylinder of the above-described structure, the electronic locking assembly 40 cannot unlock the mechanical locking assembly 30 even after the wireless power supply module 72 of the key 70 is matched with the electronic locking sensing assembly, due to the locking assembly 50. Only after the electronic locking assembly 40 is unlocked by the key 70 driving the locking assembly 50, the electronic locking assembly 40 can unlock the mechanical locking assembly 30. Therefore, the safety performance of the electromechanical lock cylinder is effectively improved through the arrangement.

From another perspective, for the structure that adopts the solenoid as electric shutting, because the solenoid is knocking, jolting, beating under the circumstances, has the risk of unexpected unblock, this scheme adopts the rotation of spacing motor of unblock blade, only when unblock blade unblock back, the motor just can rotate. Therefore, the problem of poor safety performance of the electromechanical lock cylinder is solved.

Specifically, the electronic locking assembly 40 includes a control portion 41 and a stopper portion 43. The control part 41 is movably arranged in the lock cylinder assembly 20 and is provided with a yielding hole 42; the limiting part 43 can extend into the yielding hole 42 or abut against the periphery of the control part 41; when the abdicating hole 42 moves to the position corresponding to the limiting part 43, at least a part of the limiting part 43 can enter the abdicating hole 42, and the mechanical locking component 30 can be switched from the locking position to the unlocking position; when the position-limiting portion 43 exits the abdicating hole 42, the position-limiting portion 43 is supported between the control portion 41 and the mechanical locking component 30, so that the mechanical locking component 30 is kept at the locking position. Through such a configuration, it can be ensured that only after the wireless power supply module 72 using the key 70 unlocks the electronic locking assembly 40, the abdicating hole 42 of the control part 41 of the electronic locking assembly 40 can move to the position corresponding to the limiting part 43, so that the limiting part 43 can enter the abdicating hole 42 and unlock the mechanical locking assembly 30.

However, it should be noted that the insertion of the limiting portion 43 into the abdicating hole 42 only provides a feasible condition for the mechanical locking assembly 30 to switch from the locking position to the unlocking position, and the unlocking section 71 of the key 70 is required to be inserted into the axial hole 21 to unlock the mechanical locking assembly 30.

Alternatively, the stopper portion 43 moves in the radial direction of the housing 10.

Alternatively, at least a part of the control portion 41 may be rotatable, and the rotation axis of the control portion 41 is parallel to the axial direction of the housing 10.

Through setting up like this, can carry out the overall arrangement by the inner structure of lock core more nimble to can guarantee the miniaturization of lock core.

Specifically, the control portion 41 includes the wireless power receiving module 44, the circuit assembly 45, the motor 46 and the locking rotating block 47 which are respectively arranged inside the lock cylinder assembly 20, the wireless power receiving module 44 can be electrically connected with the wireless power supply module 72, the circuit assembly 45 and the wireless power receiving module 44 are electrically connected and drive the motor 46 to act, the motor 46 can drive the locking rotating block 47 to rotate, and the locking rotating block 47 has the abdicating hole 42. Through the arrangement, when the lock cylinder is unlocked by using the key 70, the wireless power supply module 72 of the key 70 can supply power to the wireless power receiving module 44, so that the circuit component 45 can drive the motor 46 to rotate, and the abdicating hole 42 of the locking rotating block 47 can rotate along with the motor 46 until the locking rotating block rotates to the position corresponding to the limiting part 43.

Specifically, the stopper portion 43 includes a latching pin 48 and a first restoring member 49. At least a portion of the lockout pin 48 is able to enter the relief hole 42; first reset 49 provides a reset force to latch pin 48 moving toward one side of mechanical latch assembly 30. With this arrangement, when the receding hole 42 of the locking rotating block 47 rotates to the position corresponding to the stopper portion 43, the locking pin 48 can press the first returning member 49 and enter the receding hole 42. And in the process of locking the lock cylinder, the first reset piece 49 can provide reset force for the limit pin, so that the limit pin can be guaranteed to be capable of limiting the mechanical locking assembly 30 again, and meanwhile, the limit pin is separated from the abdicating hole 42, so that the locking rotating block 47 can return to the position of the lock cylinder in the locking state.

Specifically, the locking assembly 50 includes an unlocking blade 51 and a second resetting piece 52, the second resetting piece 52 provides a resetting force for the unlocking blade 51 to keep locking the electronic locking assembly 40, wherein the unlocking blade 51 has a locking protrusion 53, the electronic locking assembly 40 has a locking groove 471 matched with the locking protrusion 53, and the unlocking blade 51 also has a locking position matched with the key 70; when the key 70 is used for unlocking, the unlocking section 71 can press the unlocking blade 51 to move, so that the locking protrusion 53 unlocks the locking groove 471, and the electronic locking assembly 40 is unlocked; when the key 70 is pulled out, the unlocking blade 51 locks the locking protrusion 53 with the locking groove 471 by the second restoring member 52, and the electronic locking assembly 40 is locked. It should be noted that when the electronic locking assembly 40 is unlocked, the locking protrusion no longer limits the locking groove 471, so that the electronic locking assembly 40 can be unlocked. During latching of the electronic latching assembly 40, the latching protrusion 53 can abut against the inside of the latching groove 471 and drive the electronic latching assembly 40 to move under the restoring force provided by the second restoring member 52.

In one embodiment of the present application, a locking groove 471 is provided on the latching rotary piece 47. And, the locking protrusion 53 drives the locking rotation block 47 to rotate under the action of the second reset piece 52, so that the abdicating hole 42 is far away from the corresponding position of the limiting part 43.

Specifically, the outer side wall of the cylinder assembly 20 has a first receiving groove 22 extending along the circumferential direction, and the locking assembly 50 is located in the first receiving groove 22. With this arrangement, the first receiving groove 22 can guide the movement of the unlocking blade 51, so that the usability of the lock cylinder can be improved.

Specifically, the unlocking blade 51 is an arc-shaped blade. Through the arrangement, the unlocking process can be smoother. In addition, the lock cylinder can be more easily miniaturized by the arrangement.

Specifically, the locking groove 471 is an arc-shaped groove and has a stopping end 473, when the electronic locking assembly 40 is locked, the locking protrusion 53 is in stopping fit with the stopping end 473, and when the electronic locking assembly 40 is switched from unlocked to locked, the locking protrusion 53 pushes the stopping end 473 under the action of the second restoring member 52 to return the electronic locking assembly 40 to the locked position. By means of the arrangement, resistance generated in the unlocking process can be effectively reduced.

In the present application, when the electronic locking assembly 40 is locked, the locking protrusion 53 stops against the stopping end 473 to limit the rotation of the locking rotor; when the electronic locking assembly 40 is unlocked, the locking protrusion 53 stops against the stop end 473, such that the offset hole 42 is coaxial with the locking pin 48, thereby limiting the rotational angle of the motor 46.

Specifically, the cylinder core assembly 20 includes a front cylinder core 23 and a rear cylinder core 24. The front lock cylinder 23 has a wireless power receiving module 44; the front lock core 23 is communicated with the rear lock core 24 through the axial hole 21, the rear lock core 24 is provided with a circuit assembly 45, a motor 46 and a locking rotating block 47, and the rear lock core 24 is arranged between the front lock core 23 and the lock knob 60.

In one embodiment of the present application, the front cylinder 23 and the rear cylinder 24 are connected by a pin.

Specifically, the axial hole 21 is eccentrically disposed with respect to the axis of the front cylinder 23. Since the unlocking blade 51 is disposed between the cylinder assembly 20 and the housing 10 by engagement with the unlocking blade after the unlocking section 71 of the key 70 is inserted into the cylinder assembly 20, this requires the axial bore 21 to be disposed eccentrically with respect to the axis of the front cylinder 23.

Specifically, the outer sidewall of the cylinder core assembly 20 has a second receiving groove 25 extending in the axial direction and a third receiving groove 26 extending in the circumferential direction, and the mechanical latching assembly 30 includes a third restoring member 31, a latch 32, a fourth restoring member 33, and a mechanical ring blade 34. The latch 32 has a hollow section 321, at least a part of the latch 32 is movably disposed in the second receiving groove 25 and can rotate with the latch core assembly 20 relative to the housing 10, at least a part of the electronic locking assembly 40 can penetrate into the second receiving groove 25 to jack up the latch 32 toward one side of the housing 10, so that at least a part of the latch 32 is retained in the locking groove 11 of the housing 10 to keep the latch core assembly 20 locked with the housing 10, and the third resetting member 31 is disposed between the latch 32 and the second receiving groove 25; the fourth restoring member 33 is disposed at the third receiving groove 26 to maintain at least a portion of the latch 32 in the locking recess 11; the mechanical annular blade 34 is slidably arranged in the third accommodating groove 26, one end of the mechanical annular blade 34 passes through the hollow section 321 to be abutted against the fourth resetting piece 33, and the mechanical annular blade 34 is provided with a yielding groove 35 and a matching position; when the key 70 is used for unlocking, the unlocking section 71 extends into the inside of the cylinder assembly 20 and is matched with the matching position, so that the mechanical annular blade 34 moves along the direction of retracting the fourth resetting piece 33, when the abdicating groove 35 moves to the hollow section 321, the mechanical locking assembly 30 unlocks the latch 32, and the latch 32 can exit from the locking groove 11.

In the present application, the unlocking section 71 is provided on the key body 73, the unlocking section 71 can be inserted into the inside of the cylinder core assembly 20 of the lock cylinder, and as shown in fig. 20, the unlocking section 71 has a first unlocking position 711 which is engaged with the engagement position of the mechanical ring blade 34 of the mechanical locking assembly 30 of the lock cylinder, and a second unlocking position 712 which is engaged with the locking position of the unlocking blade 51 of the locking assembly 50 of the lock cylinder; the wireless power supply module 72 is disposed on one side of the key body 73 close to the unlocking section 71, and when the unlocking section 71 is inserted into the lock cylinder assembly 20, the wireless power supply module 72 senses the wireless power receiving module 44 of the control part 41 of the electronic locking assembly 40 of the lock cylinder and supplies power to the wireless power receiving module 44.

It should be noted that in the present application, the third returning member 31 and the mechanical ring-shaped blades 34 are both plural and correspond to each other one by one. And the abdicating groove 35 of at least one mechanical ring-shaped blade 34 is not in the same line with the abdicating grooves 35 of the other mechanical ring-shaped blades 34, when the unlocking section 71 of the key 70 is fully extended into the interior of the cylinder assembly 20, the abdicating grooves 35 of the plurality of mechanical ring-shaped blades 34 are in the same line. Through setting up like this, can improve the theftproof performance of lock core effectively.

When the key 70 is used for unlocking, the key 70 is inserted, and the first unlocking position 711 of the key 70 is engaged with the mechanical ring blade 34 and makes the relief groove 35 of the mechanical ring blade 34 correspond to the plunger 32. Meanwhile, the unlocking section 71 of the key 70 pushes the unlocking blade 51 to rotate against the spring force of the second restoring member 52, and the locking protrusion 53 on the unlocking blade 51 no longer abuts on the sidewall of the locking groove 471, and at this time, the locking rotating block 47 has a rotating space. Meanwhile, the wireless power supply module 72 communicates with the key 70, after the key 70 verifies the unlocking authority of the lock cylinder, the wireless power supply module 72 is powered, the motor 46 is powered through the wireless power receiving module 44 and the circuit component 45, the motor 46 drives the locking rotating block 47 to rotate, at the moment, the locking protrusion 53 abuts against the side wall of the locking groove 471 again, and by means of the structure, the rotation angle of the motor 46 can be limited, so that the locking pin 48 and the abdicating hole 42 are located on the same axis. At this point, the key 70 is turned, the plug 32 falls and is no longer captured between the housing and the rear cylinder 24, and the lock cylinder is in the unlocked state.

When the key 70 is used for locking, the key 70 is firstly reversely rotated to return to the original position, then the computer key 70 is pulled out, the mechanical locking component 30 returns to the default locking position, the unlocking blade 51 reversely rotates to the initial position under the action of the spring force of the second resetting piece 52, the driving part abuts against the side wall of the locking groove 471 and drives the locking rotating block 47 to reversely rotate to the initial position, at the moment, the locking pin 48 is staggered with the abdicating hole 42 by a certain angle, the locking pin 48 abuts against the outer circular surface of the locking rotating block 47, the locking pin 48 has no backward space, the locking pin 48 stops the lock bolt 32 to move downwards, the lock bolt 32 is clamped between the rear lock container 24 and the lock shell, so that the lock bolt cannot relatively rotate, and the lock core is in the locking position.

It should be noted that, if the tooth shape of the unlocking section 71 is not matched with the unlocking blade 51, after the key 70 is inserted, the locking pin 48 is not coaxial with the avoiding hole and is staggered by a certain angle, at this time, even if the circuit component 45 supplies power to the motor 46, because the rotation torque of the motor 46 is smaller than the elastic force provided by the second resetting piece 52 to the unlocking blade 51, the motor 46 cannot drive the locking rotating block 47 to rotate and is in a locked-rotor state, and through the arrangement, the working reliability of the electronic locking component 40 is ensured.

From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:
