The phrase "the clip portion 521 is aligned with the corresponding slot 511 of the identifier 510" means that the clip portion 521 can be inserted into the slot 511 corresponding to the clip portion 521 or the identifier 510 can be avoided from the slot 511 corresponding to the clip portion 521. The phrase "the card slot 511 of the identifier 510 is shifted from the corresponding card slot 521" means that the card slot 521 cannot be inserted into the card slot 511 corresponding to the card slot 521 or the identifier 510 cannot be avoided from the card slot 511 corresponding to the card slot 521, that is, the card slot 521 is blocked by the identifier 510.

By arranging a plurality of clamping parts 521 on the trigger 520, each clamping part 521 corresponds to at least one identification piece 510. When the identifier 510 is in the unlocking position, the card slot 511 on the identifier 510 is aligned with the card portion 521 on the trigger 520 corresponding to the card slot 511, and the identifier 510 allows the card portion 521 corresponding to the identifier to pass through. When the identifier 510 is in the non-unlocking position, the card slot 511 on the identifier 510 and the card portion 521 on the trigger 520 corresponding to the card slot 511 are staggered, and the card portion 521 abuts against the identifier 510 and is blocked by the identifier 510, so as to prevent the trigger 520 from being switched from the first position to the second position. That is, as long as one of the catching portions 521 cannot be aligned with the catching groove 511 corresponding to the catching portion 521, the trigger 520 is stopped. When all the clamping portions 521 are aligned with the clamping slots 511 corresponding to the clamping portions 521, the trigger 520 is no longer stopped, and the trigger 520 can be switched from the first position to the second position by the driving member 530, so as to switch the locking mechanism 300 from the first state to the second state.

In some embodiments, the mechanical identification component includes two identification members 510, and the trigger 520 is provided with two clamping portions 521, that is, the identification members 510 and the clamping portions 521 correspond to each other one by one. The two identifiers 510 and the two catching portions 521 are alternately arranged in the moving direction of the trigger 520, and the identifiers 510 are located at the end in the direction in which the trigger 520 is switched from the first position to the second position so as to block the catching portions 521. That is, the first engaging portion 521, the first identifying member 510, the second engaging portion 521 and the second identifying member 510 are arranged in a direction of the trigger 520 moving from the first position to the second position. When both identifiers 510 are in the unlocked position, the first catch 521 is aligned with the catch slot 511 on the first identifier 510 and the second catch 521 is aligned with the catch slot 511 on the second identifier 510 to allow the trigger 520 to be switched from the first position to the second position to switch the latch mechanism 300 from the first state to the second state. When at least one identification member 510 is in the non-unlocked position, for example, the first identification member 510 is in the non-unlocked position, the slot 511 of the first identification member 510 is staggered from the first latch portion 521, so as to prevent the trigger 520 from being switched from the first position to the second position. For another example, when the second identification member 510 is in the non-unlocking position, the slot 511 of the second identification member 510 is offset from the second engaging portion 521, so as to prevent the trigger 520 from being switched from the first position to the second position.

In some embodiments, the identification member 510 is cylindrical, and the slot 511 is a groove that opens in the circumferential direction of the identification member 510. Optionally, the identifier 510 includes a first segment, a second segment and a third segment, the second segment connecting the first segment and the third segment, the second segment having a diameter smaller than the first segment, the first segment having a diameter equal to the third segment. The circumferential surface of the second section, the end surface of the first section close to the second section and the end surface of the third section close to the second section together enclose a clamping groove 511.

In the present embodiment, the identifier 510 is accommodated in the second through hole 212 or corresponds to the second through hole 212, so that the mechanical key drives the identifier 510 to switch from the non-unlocking position to the unlocking position during the insertion process into the lock hole 211.

The number of identifiers 510 is not limited, and two, three, or more than three identifiers 510 may be used. The greater the number of the identification pieces 510, the more complicated the structure of the tooth, the greater the difficulty of the forced unlocking, and the higher the security of the lock cylinder 10.

In some embodiments, the number of the card slots 511 on the identifier 510 is one, and one card portion 521 corresponds to one card slot 511 on the identifier 510. In other embodiments, the number of the card slots 511 on the identifier 510 is two, and one card portion 521 corresponds to two card slots 511 on the identifier 510. However, when the identifier 510 is in the unlocking position, the clamping portion 521 can only be clamped into one of the clamping slots 511 or pass through one of the clamping slots 511, and the other clamping slot 511 acts as a disturbance, so that the difficulty of forced unlocking is further increased, and the safety of the lock cylinder 10 is improved. Of course, the identifier 510 may be provided with three or more card slots 511, and one card unit 521 may correspond to the three or more card slots 511 of the identifier 510.

In still other embodiments, the number of the card slots 511 on the identification piece 510 is two, and the trigger 520 includes two card portions 521 arranged along the moving direction of the identification piece 510, that is, two card portions 521 correspond to two card slots 511 on the same identification piece 510. In this way, when the identifier 510 is located at the unlocking position, the two clamping portions 521 are respectively clamped into the two clamping slots 511 or pass through the two clamping slots 511, so that the difficulty of forced unlocking can be increased, and the safety of the lock cylinder 10 is improved.

In an embodiment where the number of the card slots 511 on the identification member 510 is one, and one card-engaging portion 521 corresponds to one card slot 511 on the identification member 510, if the plurality of card-engaging portions 521 on the trigger 520 are arranged in a straight line along the moving direction of the trigger 520 (the plurality of card-engaging portions 521 are aligned along the moving direction of the trigger 520), then when the plurality of identification members 510 are all at the unlocking position, the plurality of card slots 511 on the plurality of identification members 510 are also arranged in a straight line along the moving direction of the trigger 520 (the plurality of card slots 511 on the plurality of identification members 510 are also aligned along the moving direction of the trigger 520), so as to allow the card-engaging portions 521 to be engaged in the card slot 511 corresponding thereto or pass through the card slot 511 corresponding thereto.

In some embodiments, the trigger 520 is configured such that when it is in the second position, the catch 521 catches in the catch slot 511 of the identifier 510 corresponding thereto, to hold the identifier 510 in the unlocked position. The mechanical identification component includes a plurality of reset members 512, the reset members 512 acting between the identification member 510 and the cylinder core 200. The reset member 512 is configured to accumulate a first elastic force when the identification member 510 is switched from the non-unlock position to the unlock position, and the first elastic force is configured to reset the identification member 510 from the unlock position to the non-unlock position when the trigger member 520 is located at the first position.

When the identifying member 510 is in the non-unlocking position, the end surface of the snap-in portion 521 along the direction in which the trigger 520 moves from the first position to the second position abuts against the identifying member 510, and the identifying member 510 prevents the trigger 520 from moving from the first position to the second position. When the trigger 520 is in the second position, an end surface of the engaging portion 521 along a direction in which the identifier 510 moves from the non-unlocking position to the unlocking position abuts against a groove wall of the engaging groove 511 to hold the identifier 510 at the unlocking position.

The resetting member 512 is provided to facilitate resetting the identification member 510 from the unlocked position to the non-unlocked position to enable reuse of the mechanical identification component. When the trigger 520 is in the second position, the engaging portion 521 is engaged with the engaging slot 511 to keep the identifier 510 at the unlocking position, so as to prevent the identifier 510 from being reset first and then blocking the trigger 520 before the trigger 520 is not reset, so that the trigger 520 cannot be reset.

In some embodiments, the trigger 520 is movably disposed on the cylinder core 200 along a first direction, and the identifier 510 is movably disposed on the cylinder core 200 along a second direction. The first direction is perpendicular to the second direction. By making the moving direction of the trigger 520 perpendicular to the moving direction of the identifiers 510, the interference between the movement of the trigger 520 and the movement of the identifiers 510 is reduced, so that the trigger 520 can move from the first position to the second position with less resistance when a plurality of identifiers 510 are in the unlocked position.

In some embodiments, the first direction is perpendicular to the extending direction of the locking hole 211, and the second direction is the same as the extending direction of the locking hole 211. By setting the second direction to be consistent with the extending direction of the lock hole 211, the mechanical key can drive the identification piece 510 to move relative to the cylinder liner 200 in the process of being inserted into the lock hole 211, so that the identification piece 510 is switched from the non-unlocking position to the unlocking position.

In other embodiments, the first direction, the second direction and the extending direction of the locking hole 211 are perpendicular to each other. The mechanical recognition assembly includes a plurality of blades arranged along an extending direction of the locking hole 211. A notch is formed in one side, facing the trigger 520, of each blade, each blade is provided with a matching portion matched with a key, when a correct mechanical key is inserted into the lock hole 211, teeth of the mechanical key can drive the plurality of blades to move along the second direction, so that the notches in the plurality of blades are arranged in a straight line, all the blades are located at an unlocking position, the plurality of notches arranged in the straight line form a groove for the trigger 520 to move from the first position to the second position, so that the trigger 520 can be switched from the first position to the second position under the action of the driving piece 530, and the locking mechanism 300 is switched from the first state to the second state. When the wrong mechanical key is inserted into the lock hole 211, all the blades cannot be in the unlocking position, that is, the notches on the blades cannot be aligned in a straight line, and a groove for moving the trigger 520 from the first position to the second position cannot be formed, so that the trigger 520 cannot be switched from the first position to the second position by the driving member 530, and the locking mechanism 300 is maintained in the first state. Through setting up a plurality of blades, increased the degree of difficulty that violence unblanked, increased the security of lock core 10.

In still other embodiments, the mechanical identification component includes a plurality of identification members 510 arranged in a first direction. Each identification piece 510 is provided with a through hole. When a correct mechanical key is inserted into the lock hole 211, all the identification pieces 510 can be located at the unlocking position, and at this time, the plurality of through holes originally staggered are arranged in a straight line in the first direction, so that the trigger piece 520 can be moved from the first position to the second position along the first direction under the action of the driving piece 530, and the locking mechanism 300 can be switched from the first state to the second state. When the wrong mechanical key is inserted into the lock hole 211, all the identification members 510 cannot be in the unlocking position (i.e., at least one identification member 510 is in the non-unlocking position), and at this time, some of the through holes are not aligned in a straight line, so that the trigger 520 is blocked by the identification members 510 and cannot reach the second position from the first position, and the locking mechanism 300 is maintained in the first state.

In some embodiments, the trigger 520 has a hook 522, the end surface of the cam 310 is protruded with an abutting portion 311, and the hook 522 is hooked on the abutting portion 311. The hook 522 is configured to drive the cam 310 to rotate from the third position to the fourth position during the switching of the trigger 520 from the first position to the second position. By providing the hook portion 522 on the trigger 520 so as to hook the abutment 311 on the cam 310, force is transferred to drive the cam 310 to rotate from the third position to the fourth position during the switching of the trigger 520 from the first position to the second position.

In some embodiments, the mechanical unlocking mechanism further includes a guide 540, the guide 540 is disposed in the cylinder core 200, and the guide 540 is used for guiding the trigger 520. The guide 540 is arranged to guide the trigger 520, so that the trigger 520 can only move along the route defined by the guide 540, the structural stability of the lock cylinder 10 is improved, and the possibility of the lock cylinder 10 failure is reduced.

Optionally, the guide 540 has a strip hole 541 formed therein, and the strip hole 541 extends along the first direction. The trigger 520 is provided with a supporting protrusion 523, the supporting protrusion 523 is accommodated in the bar-shaped hole 541, and the driving element 530 acts on the supporting protrusion 523. In the extending direction of the bar-shaped hole 541, the length of the holding protrusion 523 is smaller than that of the bar-shaped hole 541, so that the holding protrusion 523 can move in the bar-shaped hole 541 along the extending direction of the bar-shaped hole 541. In the width direction of the bar-shaped hole 541, the length of the holding protrusion 523 is equal to the width of the bar-shaped hole 541, so as to limit the movement of the holding protrusion 523 along other directions except the first direction.

In some embodiments, the upper surface of the guide 540 extends in a first direction, and the trigger 520 is provided with a first guide protrusion 524 protruding thereon, and the first guide protrusion 524 is engaged with the upper surface of the guide 540 to guide the guide 540. The lower surface of the guide member 540 extends along the first direction, and a second guide protrusion 525 is further protruded on the trigger member 520, and the second guide protrusion 525 is engaged with the lower surface of the guide member 540 to guide the guide member 540.

In some embodiments, the driving member 530 is an elastic element acting between the trigger 520 and the cylinder core 200, and the elastic element is configured to accumulate a second elastic force during the switching of the trigger 520 from the second position to the first position, and the second elastic force is configured to drive the trigger 520 to switch from the first position to the second position when the mechanical identification component is in the fourth state. The elastic element is selected as the driving member 530, and the elastic element can store elastic potential energy and use the elastic potential energy to drive the triggering member 520 to switch from the first position to the second position without an additional power source.

In other embodiments, the driving member 530 and the triggering member 520 are both magnets. The driving member 530 attracts or repels the trigger 520 to drive the trigger 520 from the first position to the second position.

In some embodiments, referring to fig. 1, 2, 3, and 4, the lock cylinder 10 further includes a reset mechanism 600, wherein the reset mechanism 600 acts between the locking mechanism 300 and the cylinder core 200. The reset mechanism 600 is used to switch the locking mechanism 300 from the second state to the first state when the mechanical key is pulled out of the keyhole 211, and to drive the trigger 520 to reset from the second position to the first position. Through setting up canceling release mechanical system 600 to reset locking mechanism 300, with locking mechanism 300 switches over the second state to the first state, make and need not other operations after extracting mechanical key and can make lock core 10 resume electronics unblock and promptly unblock function again, it is comparatively convenient.

In some embodiments, the return mechanism 600 has a fifth state and a sixth state, the return mechanism 600 being configured to prevent the locking mechanism 300 from switching from the first state to the second state when it is in the fifth state, the return mechanism 600 being further configured to allow the locking mechanism 300 to switch from the first state to the second state when it is in the sixth state. The lock cylinder 10 further includes an unlocking member 610, and the unlocking member 610 is movably disposed in the cylinder core 200 along an extending direction of the lock hole 211. During the process of inserting the electronic key or the mechanical key into the keyhole 211, the electronic key or the mechanical key can push the unlocking member 610 to move forward relative to the cylinder core 200, so as to switch the reset mechanism 600 from the fifth state to the sixth state. In the process of pulling out the electronic key or the mechanical key from the key hole 211, the unlocking member 610 can move in the reverse direction with respect to the cylinder barrel 200, and the reset mechanism 600 is switched from the sixth state to the fifth state. In the process of switching the reset mechanism 600 from the sixth state to the fifth state, the reset mechanism 600 switches the locking mechanism 300 from the second state to the first state and drives the trigger 520 to reset from the second position to the first position.

When the electronic key and the mechanical key are inserted into the lock hole 211, it is first verified whether they can act on the unlocking member 610, so that the unlocking member 610 switches the reset mechanism 600 from the fifth state to the sixth state, and if the reset mechanism 600 cannot be successfully switched, it indicates that the key is wrong, and unlocking cannot be performed. If the reset mechanism 600 can be successfully switched, the identity information of the electronic key or the correctness of the mechanical key is continuously verified. By this arrangement, the security of the lock cylinder 10 is further enhanced, and the possibility of violent unlocking is reduced. In addition, the reset mechanism 600 can also switch the locking mechanism 300 from the second state to the first state in the process of switching from the sixth state to the fifth state, and one reset mechanism 600 achieves multiple functions, thereby being beneficial to simplifying the structure and reducing the volume of the lock cylinder 10.

Optionally, the mounting base 220 is provided with a fourth through hole 222, and the unlocking member 610 is disposed through the fourth through hole 222 to be movably connected with the cylinder core 200. The reset mechanism 600 includes a limiting block 620, the limiting block 620 is movably disposed on the lock core 200, and a moving direction of the limiting block 620 is perpendicular to a moving direction of the unlocking member 610. The unlocking piece 610 is provided with a first guiding inclined surface 611, the limiting piece is provided with a second guiding inclined surface 621, and the unlocking piece 610 and the limiting piece 620 are matched through the first guiding inclined surface 611 and the second guiding inclined surface 621, so that the unlocking piece 610 can drive the limiting piece 620 to move. The stopper 620 has a fifth position and a sixth position, and when the stopper 620 is at the fifth position, the reset mechanism 600 is in a fifth state. When the stop block 620 is at the sixth position, the reset mechanism 600 is in the sixth state.

During the process of inserting the electronic key or the mechanical key into the lock hole 211, the electronic key or the mechanical key can push the unlocking piece 610 to move forward relative to the cylinder core 200 to drive the limiting block 620 to move from the fifth position to the sixth position, so as to switch the reset mechanism 600 from the fifth state to the sixth state, and allow the locking mechanism 300 to switch from the first state to the second state. In the process of pulling out the electronic key or the mechanical key from the keyhole 211, the stop block 620 can move from the sixth position to the fifth position relative to the cylinder barrel 200 to drive the unlocking piece 610 to move reversely relative to the cylinder barrel 200, and the reset mechanism 600 is switched from the sixth state to the fifth state to prevent the locking mechanism 300 from being switched from the first state to the second state.

The return mechanism 600 includes a second return spring 630, and the second return spring 630 acts between the stop block 620 and the cylinder core 200. The second return spring 630 is used to accumulate a third elastic force in the process of switching the stopper 620 from the fifth position to the sixth position, the third elastic force is used to drive the stopper 620 to return to the fifth position from the sixth position, and simultaneously drive the unlocking member 610 to move in the opposite direction relative to the cylinder core 200, and the return mechanism 600 is switched from the sixth state to the fifth state.

In some embodiments, the stop block 620 has a third guiding ramp 622 thereon. When the stop block 620 is located at the sixth position and the cam 310 is located at the fourth position, the abutting portion 311 of the cam 310 abuts against the third guiding inclined surface 622, the third guiding inclined surface 622 is configured to drive the abutting portion 311 to rotate during the process of pulling out the electronic key or the mechanical key from the lock hole 211, so as to drive the cam 310 to switch from the fourth position to the third position, and the locking mechanism 300 switches from the second state to the first state.

Optionally, the stop block 620 further has an abutting surface 623, the abutting surface 623 is connected to the third guiding inclined surface 622, and the abutting surface 623 is configured to be abutted by the abutting portion 311 when the stop block 620 is located at the fifth position, so as to prevent the cam 310 from rotating from the third position to the fourth position, i.e., prevent the locking mechanism 300 from switching from the first state to the second state. When the stopper 620 is at the sixth position, the abutting surface 623 is away from the abutting portion 311, that is, the abutting portion 311 no longer abuts against the abutting surface 623, and the reset mechanism 600 allows the cam 310 to rotate from the third position to the fourth position, allowing the locking mechanism 300 to switch from the first state to the second state. When the cam 310 rotates from the third position to the fourth position, the abutting portion 311 abuts against the third guiding inclined surface 622, so that the cam 310 is driven by the limiting block 620 in the process of pulling out the electronic key or the mechanical key from the lock hole 211, and the cam 310 is switched from the fourth position to the third position, and the locking mechanism 300 is switched from the second state to the first state.

Since the hook 522 of the trigger 520 is hooked on the abutting portion 311, the abutting portion 311 drives the hook 522 to move in the process of switching the cam 310 from the fourth position to the third position, so that the trigger 520 is reset from the second position to the first position. In the present embodiment, the reset mechanism 600 drives the cam 310 to reset from the fourth position to the third position, and the cam 310 drives the trigger 520 to switch from the second position to the first position, which corresponds to that the reset mechanism 600 indirectly drives the trigger 520 to reset from the second position to the first position.

It should be noted that, in the present embodiment, the mechanical unlocking mechanism is disposed at the tail portion of the lock cylinder 10, on one hand, the length of the lock cylinder 10 can be extended to increase the tooth amount of the identification piece 510, so as to reduce the mutual opening rate. On the other hand, it is not easily removed by violent destruction.
