The third elastic member 527 is a linear spring, and the linear spring can drive the top block 525 to move away from the driving assembly 40 when the rotating piece 524 no longer presses the top block 525, so that the stopping protrusion no longer locks the driving assembly 40, and the driving assembly 40 can move freely, thereby realizing automatic unlocking of the driving assembly 40.

As shown in fig. 3, 6 to 9, the driving assembly 40 includes a driving motor 41 and a cam 42, the cam 42 is connected to an output end of the driving motor 41 in a driving manner, a circumferential surface of the cam 42 has a first recess 421 into which the mechanical assembly 50 extends, and a second recess 422 into which the locking member 30 extends, when the driving assembly 40 is located at the driving stopping position, the mechanical assembly 50 can extend into the first recess 421 to lock the cam 42, the second recess 422 is relatively misaligned with the locking member 30, the locking member 30 cannot extend into the second recess 422, the locking member 30 cannot be switched to the unlocking position, when the driving assembly 40 is located at the driving avoiding position, the mechanical assembly 50 exits the first recess 421, the cam 42 rotates to a position where the second recess 422 faces the locking member 30, and a portion of the locking member 30 can extend into the second recess 422 to be switched from the locking position to the unlocking position.

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

As shown in fig. 9, 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 avoiding position, the end of the first recess 421 with the larger radial depth faces the mechanical assembly 50, when the driving assembly 40 is located at the driving stopping position, the end of the first recess 421 with the smaller radial depth faces the mechanical assembly 50, and the mechanical assembly 50 can press the inner wall of the first recess 421 to drive the driving assembly 40 to switch to the driving stopping position. Thus, when the blade 51 presses the side post to reset the side post assembly 52, the stop protrusion on the top block 525 presses the side wall of the first recess 421, and since the depth of the first recess 421 is continuously changed, the stop protrusion can drive the cam 42 to rotate by pressing the side wall of the first recess 421, so that the cam 42 is switched from the drive avoiding position to the drive stop position, and the locking member 30 is automatically locked again. The lock core does not need to be powered on when reset by the arrangement mode, and automatic reset can be realized through a mechanical structure.

As shown in fig. 6 to 8, the cam 42 has a limiting protrusion 423, the lock core 20 has a limiting sliding groove, and the limiting protrusion 423 extends into the limiting sliding groove and moves in the limiting sliding groove to control the rotation range of the cam 42, so as to avoid the situation that the cam 42 is rotated to be over-positioned and cannot be recovered, ensure the normal operation of the lock cylinder, and prevent the cam 42 from rotating due to the impact of external force, thereby avoiding the accidental unlocking of the lock cylinder. The limit projection 423 may be a cylindrical projection on the end face of the cam 42 or a cylindrical projection on the circumferential face of the cam 42, and is positioned to avoid positional interference between the limit projection 423 and the stop projection and the latch member 30.

In the present embodiment, the latch member 30 is spherical, and accordingly, the shape of the second recess 422 is adapted to the shape of the latch member 30, when the cylinder is unlocked, the cylinder core 20 rotates relative to the lock housing 10, the lock housing 10 presses the latch member 30 to drive the latch member 30 to exit the lock housing 10, the cylinder core 20 can rotate relative to the lock housing 10, when the cylinder is reset, the cam 42 rotates reversely under the pressing of the stop protrusion, and the inner wall of the second recess 422 presses the latch member 30 to re-extend the latch member 30 into the lock housing 10, thereby completing the re-locking of the cylinder.

It should be noted that the lock core 20 has a blind hole into which an unlocking key is inserted, the blind hole is used as an unlocking hole, and the blind hole is separated from the driving assembly 40, so that a structure related to the driving assembly 40 does not appear in the unlocking hole of the lock core, and the driving assembly 40 cannot be cracked from the outside of the lock core, thereby improving the anti-theft performance of the lock core and ensuring the safety of the lock core.
