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

As shown in fig. 3 and 6 to 9, 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, a circumferential surface of the cam 42 has a first concave portion 421 into which the mechanical assembly 50 extends, and a second concave portion 422 into which the locking member 30 extends, when the driving assembly 40 is located at the driving stop position, the mechanical assembly 50 can extend into the first concave portion 421 to lock the cam 42, the second concave portion 422 is dislocated relative to the locking member 30, the locking member 30 cannot extend into the second concave portion 422, the locking member 30 cannot be switched to the unlocking position, when the driving assembly 40 is located at the driving avoidance position, the mechanical assembly 50 is withdrawn from the first concave portion 421, the cam 42 is rotated to a position in which the second concave portion 422 faces the locking member 30, and a part of the locking member 30 can extend into the second concave portion 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 source, and is powered by the unlocking key, so that it is unnecessary to provide a power source on the lock cylinder, thereby avoiding the trouble of charging and reducing the structural complexity of the lock 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 stop 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 avoidance 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 stop position. Thus, when the vane 51 presses the jamb such that the jamb assembly 52 is restored, the stopping protrusion of the top block 525 presses the sidewall of the first recess 421, and since the depth of the first recess 421 is continuously varied, the stopping protrusion 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 stopping position, thereby automatically locking the latch 30 again. The arrangement mode enables the lock cylinder not to be electrified when reset, and automatic reset can be achieved through a mechanical structure.

As shown in fig. 6 to 8, the cam 42 has a limiting protrusion 423, the lock cylinder 20 has a limiting chute, the limiting protrusion 423 extends into the limiting chute and moves in the limiting chute to control the rotation range of the cam 42, so as to avoid the situation that the cam 42 cannot recover due to the rotation of the cam 42, ensure the normal work of the lock cylinder, and simultaneously prevent the cam 42 from rotating due to the impact of external force, and avoid the unexpected unlocking of the lock cylinder. The limiting projection 423 may be a cylindrical projection on the end surface of the cam 42 or a cylindrical projection on the circumferential surface of the cam 42, and the position is set so as to avoid positional interference between the limiting projection 423 and the stopper projection and the latch 30.
