It can be understood that the surface of the lock core 22 facing the key 1 is provided with the large slot 2201 and the small slot 2202 for positioning the key 1 , and the head of the lock rod 23 is conical.

[0045] It should be noted that the key 1 is provided with a working indicator light 1004 for energizing the motor 6; when the lock 2 detects that the key 1 is the correct key, the working indicator light 1004 turns green, and the power supply immediately energizes the motor 6 for 2 to 3 seconds, and when the green working indicator light 1004 turns off, the motor 6 is immediately powered off, so that the green working indicator light 1004 is on for a slightly longer time than the energizing time of the motor 6. When the key 1 is inserted into the lock cylinder 22, the key 1 can be rotated to unlock the lock only when the working indicator light 1004 turns green.

[0046] Please refer to Fig.10a and Fig.10b , Fig.10a for Figure 1 The cross-sectional view of the lock after unlocking is shown. Fig.10b for Fig.10a The cross-sectional view of the lock after unlocking along the AA line is shown. When the key 1 is inserted into the lock core 22, the power supply in the key 1 energizes the motor 6, and the transmission shaft 601 of the motor 6 drives the sleeve 8 and the turntable 9 to rotate synchronously, so that the limiting protrusion 901 of the turntable 9 rotates against the side wall of the first groove 101 of the lock core inner shell 10 and stops rotating, so that the cylindrical groove 902 of the turntable 9 is aligned toward the lock rod 23, and at the same time the reset spring 7 is compressed, the key 1 drives the lock core 22 to rotate, the head of the lock rod 23 escapes from the lock rod limiting groove 211 of the lock core outer shell 21, and the lock rod spring 24 is compressed to achieve unlocking.

[0047] It can be understood that, in the process of unlocking, the key 1 drives the lock core 22 to rotate, so that the large block 1001 and the small block 1002 are disengaged from the alignment position of the large slot 212 and the small slot 213, and the large block 1001 and the small block 1002 are blocked by the inner wall 215 of the slot, and the key 1 cannot pull out the lock core 22.

At this time, the cylindrical side wall of the turntable 9 presses against the tail of the lock rod 23 to achieve locking.

[0050] It is understandable that, in the locking process, when the key 1 drives the lock core 22 to rotate until the head of the lock rod 23 is aligned with the lock rod limiting groove 211, the lock rod spring 7 is reset, so that the head of the lock rod 23 is stuck in the lock rod limiting groove 211, and at the same time, the large block 1001 and the small block 1002 are aligned with the large notch 212 and the small notch 213, and the key 1 can be pulled out. It is understandable that, since the lock 2 has its own ID, the key 1 can only unlock the corresponding lock 2 under authorization.

[0051] It should be noted that when the key 1 is inserted into the lock cylinder 22 for a period of time and is not rotated, the key 1 stops supplying power to the motor 6, the turntable 9 automatically resets, and the cylindrical side wall of the turntable 9 abuts against the tail of the lock rod 23, returning to the locked state.

[0052] When the key 1 is inserted into the lock core 22, the motor 6 is powered off by the power-on time set by the copper needle PCB board 3, and the power-on time is 2 to 3 seconds. When the key 1 is rotated to the locked position and the lock rod 23 is inserted into the limit groove 211, if the motor 6 is powered off before the key 1 is pulled out, the reset spring 7 will reset immediately after the lock rod 23 is inserted into the limit groove 211, so that the cylindrical groove 902 of the turntable 9 is separated from the lock rod 23 alignment position, and the cylindrical side wall of the turntable 9 is against the tail of the lock rod 23; if the motor 6 is still in the power-on state, after the key is pulled out, the reset spring 7 resets, so that the cylindrical groove 902 of the turntable 9 is separated from the lock rod 23 alignment position, and the cylindrical side wall of the turntable 9 is against the tail of the lock rod 23, so as to improve the service life of the lock assembly 100 and save electricity.
