It should be noted that, in addition to the effect of locking the lock cylinder 20 by the locking member 30, the blade 60 also has the effect of locking the lock cylinder 20, when the lock cylinder is not unlocked, a part of the blade 60 extends into the lock case 10, and another part is located in the lock cylinder 20, so that the blade 60 and the locking member 30 jointly lock the lock cylinder 20, so that the lock cylinder 20 cannot rotate relative to the lock case 10, and when the unlocking key is inserted into the lock cylinder, the unlocking key drives the blade 60 to move, so that the blade 60 moves from the blade stop position to the blade avoiding position, thereby unlocking the blade 60.

As shown in fig. 2 and 3, the end surface of the stopper 50 near the blade 60 has a protruding structure 52, the blade 60 has a receiving recess 61, when the lock cylinder is not unlocked, the receiving recess 61 is dislocated from the protruding structure 52, the protruding structure 52 cannot go deep into the receiving recess 61 but abuts against the outer wall surface of the blade 60, so that it cannot move, when the lock cylinder is unlocked, the blade 60 moves to the blade avoiding position, the protruding structure 52 is aligned with the receiving recess 61, the stopper 50 can move, the protruding structure 52 protrudes into the receiving recess 61, and at the same time, the stopper end 51 is withdrawn from the driving assembly 40, and the driving assembly 40 can move from the driving stop position to the driving avoiding position. Thus, when the unlocking key is inserted, the locking piece 30 is initially unlocked, the driving assembly 40 is unlocked, and then the lock cylinder can be unlocked only by supplying power to the driving assembly 40 after the unlocking key is successfully matched with the driving assembly 40.

The blade 60 is generally provided in plurality, and in this embodiment, when the blade 60 is moved to the blade escape position, the accommodating recess 61 on each blade 60 is communicated in the direction in which the unlocking key is inserted into the key cylinder to form a straight communication groove. Accordingly, the projecting structure 52 also extends a distance in the direction of insertion of the unlocking key into the lock cylinder such that there is a mating relationship between the projecting structure 52 and each of the blades 60, the blades 60 not stopping the stop 50 only when all of the blades 60 are moved to the blade-dodging position. Of course, the accommodating recess 61 of each blade 60 may not be formed as a straight communication groove, but may be individually engaged with the corresponding projecting structure 52 of the stopper 50.

The stopper 50 in this embodiment is a plate-shaped member, a slot into which the locking member 30 extends is formed in the stopper 50, and an extending structure 52 is disposed on an end surface of the stopper 50 facing away from the insertion of the locking member 30, that is, the stopper 50 is located between the locking member 30 and the vane 60, so that the vane 60 can stop the locking member 30 by stopping the stopper 50. The portion of the latch 30 that extends into the slot may be fully received in the slot or may extend partially through the slot to form a portion similar to the extension 52 that extends into the blade 60 when the latch 30 is moved.

In this embodiment, the lock cylinder further includes an elastic member 70, both ends of the elastic member 70 respectively abut against the locking member 30 and the stopper 50 to drive the protruding structure 52 on the stopper 50 to protrude into the accommodating recess 61 when the blade 60 moves to the blade escape position, while unlocking the driving assembly 40. The elastic member 70 is a linear spring, and the elastic member 70 is disposed between the stopper 50 and the locking member 30, so that the locking member 30 and the stopper 50 have a tendency to move away from each other, and thus, when the vane 60 moves to the vane avoiding position, the elastic member 70 drives the stopper 50 to move, pushing the protruding structure 52 into the accommodating recess 61, and unlocking the driving assembly 40 is achieved. Because the elastic member 70 is present, the locking member 30 always has a movement trend of extending into the lock housing 10, and cannot be automatically switched to the unlocking position, so that an extrusion inclined plane is disposed at one end of the locking member 30 extending into the lock housing 10, when the locking member 30 is fully unlocked, the unlocking key is rotated, the unlocking key drives the lock cylinder 20 to rotate together, the lock housing 10 extrudes the extrusion inclined plane on the locking member 30, so that the locking member 30 is withdrawn from the lock housing 10 to move to the unlocking position, the lock cylinder 20 can rotate relative to the lock housing 10, and when the lock cylinder 20 is rotated back to the locking position, the elastic member 70 can also drive the locking member 30 to automatically extend into the lock housing 10.

Optionally, the side walls of the receiving recess 61 have ramp structures 611, the ramp structures 611 pressing against the projecting structure 52 to drive the projecting structure 52 out of the receiving recess 61 when the blade 60 is moved from the blade-dodging position to the blade-stop position. When the lock cylinder needs to be locked again, the lock cylinder 20 is rotated back to the original position, the unlocking key is pulled out, the blade 60 is reset under the action of the blade spring in the process of pulling out the unlocking key, and the inclined surface structure 611 of the accommodating concave part 61 presses the extending structure 52 on the locking piece 30 in the process of resetting the blade 60, so that the extending structure 52 exits the accommodating concave part 61, and the stopping piece 50 and the locking piece 30 are pressed back to the lock cylinder locking position again by the blade 60, thereby realizing the reset of the lock cylinder. The receiving recess 61 may be provided in a triangular shape, a boss shape, or other shape having an inclined surface as needed, but may not be provided in a rectangular shape, and accordingly, the shape of the protruding structure 52 may be adapted to the shape of the receiving recess 61.

As shown in fig. 4 to 7, the driving assembly 40 includes a driving motor 41 and a cam 42, the cam 42 is in driving connection with an output end of the driving motor 41, and the driving motor 41 is energized to drive the cam 42 to rotate, thereby switching the cam 42 between a driving stop position and a driving avoidance position. The cam 42 has a first recess 421 into which the stop end 51 extends and a second recess 422 into which a portion of the latch 30 extends, the stop end 51 being able to extend into the first recess 421 to lock the cam 42 when the drive assembly 40 is in the drive-stop position, the second recess 422 being relatively misaligned with the latch 30, the latch 30 being unable to extend into the second recess 422, the latch 30 being unable to be switched to the unlocked position, the stop end 51 being withdrawn from the first recess 421 when the drive assembly 40 is in the drive-escape position, the cam 42 being rotated to a position in which the second recess 422 faces the latch 30, a portion of the latch 30 being able to extend into the second recess 422 to switch from the locked position to the unlocked position.

It should be noted that, the driving assembly 40 of the present embodiment does not have a power source, and is powered by the unlocking key, so that the power source is not required to be disposed on the lock cylinder, thereby avoiding the trouble of charging and reducing the structural complexity of the lock cylinder.

In the present embodiment, the latch 30 has the protruding structure 31 provided protruding, when the driving assembly 40 is located at the driving stop position, the protruding structure 31 is dislocated from the second recess 422, the outer wall surface of the cam 42 stops the protruding structure 31 to block the movement of the latch 30, when the driving assembly 40 is located at the driving escape position, the protruding structure 31 is aligned with the second recess 422, the protruding structure 31 can protrude into the second recess 422, and the latch 30 is switched from the locking position to the unlocking position.

Alternatively, the stopper end 51 and the boss structure 31 are disposed opposite to each other in the circumferential direction of the cam 42, and the stopper end 51 and the boss structure 31 protrude toward each other, and accordingly, the first concave portion 421 and the second concave portion 422 are also disposed at opposite sides of the cam 42. Of course, the positional relationship between the stopper end 51 and the projection 31 may be set accordingly according to actual demands.

As shown in fig. 6 and 7, the first recess 421 extends along the circumferential direction of the cam 42, the radial depth of the first recess 421 gradually increases or decreases along the circumferential direction of the cam 42, when the driving assembly 40 is located at the driving stop position, the end of the first recess 421 with the larger radial depth faces the stop end 51, when the driving assembly 40 is located at the driving avoidance position, the end of the first recess 421 with the smaller radial depth faces the stop end 51, at this time, if the unlocking key is withdrawn from the lock cylinder, the blade 60 presses the stop member 50 under the action of the blade spring, so that the stop end 51 presses the inner wall of the first recess 421 to drive the driving assembly 40 to the driving stop position. Thus, when the vane 60 presses the stopper 50 to reset the stopper 50, the stopper end 51 of the stopper 50 presses the sidewall of the first recess 421, and since the depth of the first recess 421 is continuously varied, the stopper end 51 can be rotated by pressing the sidewall driving cam 42 of the first recess 421, so that the cam 42 is switched from the driving escape position to the driving stop position, thereby automatically locking the latch 30 again.

The lock core of this embodiment has the unblock hole that supplies the unblock key to insert, and a part of blade 60 is located the unblock hole, and the unblock key inserts in the unblock hole and can drive blade 60 motion, and drive assembly 40 separates the setting with the unblock hole to only have the relevant part of blade 60 in the feasible unblock hole, do not relate to the part of drive assembly 40, when the lock core is pried, the foreign matter can not touch drive assembly 40 after getting into from the unblock hole, just can't stir drive assembly 40 and move to the drive and dodge the position, has improved the security of lock core.
