Specifically, when the key is used for locking, the rotating key drives the front lock core 11 to rotate, the front lock core 11 drives the rear lock core 13 to rotate through the middle lock core 12, at least one part of the locking component 20 extends into the locking groove 14, then the key is pulled out, the clutch component 40 returns to the initial position and limits the limiting component 30, and meanwhile, the limiting component 30 limits the locking component 20 so that the locking component 20 is kept at the locking position. It should be noted that the initial position in the above is the position where each component inside the lock case 10 is located when the centrifugal electronic lock cylinder is in the locked state. In the locking by using the key, the clutch unit 40, the stopper unit 30, and the lock unit 20 are sequentially returned to the initial positions, and at this time, the clutch unit 40 stops the stopper unit 30, and the stopper unit 30 can stop the lock unit 20, so that the lock unit 20 is held at the locked position, and the centrifugal electronic key cylinder is held at the locked state.

Alternatively, the key is an electronic key, and the clutch assembly 40 can be sensed with the key to rotate the clutch assembly 40. It should be noted that, the centrifugal electronic lock cylinder in the present application is mainly an electronic lock cylinder driven by a motor.

As shown in fig. 3, the clutch assembly 40 includes at least one clutch piece 41, the clutch piece 41 moves in the radial direction of the lock case 10, and when the centrifugal electronic key cylinder is in the locking state, the clutch piece 41 limits the limiting assembly 30 to keep the locking assembly 20 in the locking position.

As shown in fig. 1, 2, 4 and 5, the clutch assembly 40 further includes a base 42 and a drive assembly 43. The base 42 is arranged on one side of the middle lock core 12 close to the rear lock core 13, the base 42 is provided with at least one long sliding hole 421, at least one part of each clutch block 41 is in sliding fit with the corresponding long sliding hole 421, so that the base 42 is connected with the clutch block 41, and the movement range of the clutch block 41 in the base 42 is limited; the driving assembly 43 is drivingly connected to the base 42 to drive the base 42 to rotate. Through setting up like this, when using the key to unblock centrifugal electron lock core, drive assembly 43 drive base 42 rotates, separation and reunion piece 41 can be along the slot hole 421 motion of sliding towards lock shell 10 under the effect of centrifugal force this moment to can relieve spacing to spacing subassembly 30, treat to rotate the key after, preceding lock courage 11 drives back lock courage 13 and rotates, shutting subassembly 20 can be switched to the unblock position by the shutting position, and extrude spacing subassembly 30 and move towards preceding lock courage 11, thereby accomplish the unblock.

As shown in fig. 1, clutch assembly 40 further includes a clutch reset member 44, and during the locking process of the centrifugal electronic key cylinder, since base 42 stops rotating, clutch block 41 can return to the position before unlocking, i.e., the initial position, under the reset force provided by clutch reset member 44, so that the reset of clutch block 41 can be realized while the locking process is completed.

It should also be noted that clutch return 44 in the present application is only in abutment with base 42 and clutch piece 41, as opposed to a conventional lock cylinder, and drives clutch piece 41 to return after clutch assembly 40 has stopped rotating. Therefore, the clutch reset piece has the characteristic of simple structure, and a sensor is not needed in the working process.

In one embodiment of the present application, the number of the long slide holes 421 is 4, the number of the clutch pieces 41 is two, and each clutch piece 41 is engaged with two adjacent long slide holes 421, respectively. Of course, the number of the long sliding holes 421 and the number of the clutch pieces 41 can be adjusted at the same time, as long as it is ensured that the clutch pieces 41 can keep matching with the long sliding holes 421 and can limit and give way the limiting assembly 30.

Optionally, a seat 42 is located within the middle lock cylinder 12. And base 42 has a receiving cavity capable of receiving clutch block 41.

As shown in fig. 1 and 2, the base 42 includes a bottom plate 422 and a shield 423.

Optionally, the bottom plate 422 and the shield 423 are of an integrally molded structure or a segmented molded structure.

In one embodiment of the present application, the axis of the bottom plate 422 coincides with the rotation center of the driving assembly 43, and the bottom plate 422 has a long sliding hole 421; the guard plate 423 is arranged along the circumferential direction of the bottom plate 422 and extends towards the rear lock liner 13 to form a clutch cavity with the bottom plate 422, and the clutch block 41 is arranged in the clutch cavity; when drive assembly 43 is rotated, clutch piece 41 is centrifugally moved and moved in an axial direction away from base plate 422; one end of clutch return 44 abuts shield 423 and the other end of clutch return 44 abuts clutch block 41 to provide clutch block 41 with a return force that moves toward the center side of bottom plate 422. Through the arrangement, the clutch block 41 can be effectively ensured to return to the position before unlocking, namely the initial position, under the action of the clutch reset piece 44 after the base 42 stops rotating, so that the service performance of the centrifugal electronic lock cylinder is effectively ensured.

It should be noted that in the present application, only clutch return member 44 provides a return force to clutch block 41. Therefore, the problems that the number of parts is increased and the material, manufacturing, installation and maintenance costs are increased for realizing the resetting of the clutch block 41 in the prior art are effectively solved. As shown in fig. 3, clutch block 41 includes a main body portion 411, at least one extension 412, and guide posts 413. The protruding portion 412 extends in a direction perpendicular to the main body portion 411 and protrudes into the long slide hole 421; the main body 411 has a guiding groove 4111, the guiding pillar 413 is disposed in the guiding groove 4111, at least a portion of the guiding pillar 413 extends from the guiding groove 4111, and the clutch return member 44 of the clutch assembly 40 extends into the guiding groove 4111 and is disposed outside the guiding pillar 413. Through setting up extension 412, can make extension 412 stretch into inside the slot hole 421 that slides to can guarantee that clutch piece 41 can follow the length direction motion of slot hole 421 that slides, and then can carry out spacingly to the motion of clutch piece 41 in slot hole 421 that slides effectively. The purpose of the guiding groove 4111 and the guiding column 413 is to ensure a stable connection between the clutch block 41 and the clutch return member 44, so as to ensure that the clutch block 41 can press the clutch return member 44 along the telescopic direction of the clutch return member 44, thereby preventing the clutch return member 44 from deflecting during pressing the clutch return member 44.

As shown in fig. 1 and fig. 4 to 13, there are two clutch blocks 41, two clutch blocks 41 are symmetrically disposed, each clutch block 41 includes two protruding portions 412, the two protruding portions 412 are respectively disposed at two ends of the main body portion 411, the number of the long sliding holes 421 is four, and different protruding portions 412 respectively protrude into different long sliding holes 421. By arranging the extending part 412 on each clutch block 41, the clutch block 41 can be effectively ensured to have certain angle deflection in the process of moving along the sliding long hole 421, the whole stress of the clutch block 41 is more stable, the stability of the movement of the clutch block 41 is ensured, and the deviation of the movement path of the clutch block 41 can be effectively prevented. In addition, the center of mass of the system formed by the clutch block 41 and the base 42 can be kept on the rotation axis by the arrangement, so that the system is kept in a dynamic balance state, and vibration is reduced.

It should be noted that in one embodiment of the present application, there are two clutch blocks 41, and when the centrifugal electronic lock cylinder is in the locked state, the two clutch blocks 41 approach each other and limit the limiting assembly 30. When the centrifugal electronic lock cylinder is switched from the locked state to the unlocked state, the two clutch pieces 41 move away from each other and move towards the lock case 10 under the action of centrifugal force. When the centrifugal electronic lock cylinder is switched from the unlocked state to the locked state, the two clutch pieces 41 move toward each other.

As shown in fig. 1, 4, 5, 9 and 10, the drive assembly 43 includes a drive motor 431 and an induction circuit 432. The driving motor 431 can drive the base 42 to rotate; the sensing circuit 432 is arranged on one side of the middle lock core 12 close to the front lock core 11 and is electrically connected with the driving motor 431, one side of the sensing circuit 432 far away from the driving motor 431 is also provided with an electrode 433, and at least one part of the electrode 433 extends into the front lock core 11 and can sense a key. Through setting up like this, can realize controlling driving motor 431 through the interact of key and induction circuit 432 to make driving motor 431 drive base 42 and rotate, thereby drive separation and reunion piece 41 and make spacing subassembly 30 can be along the direction motion towards preceding lock courage 11, thereby after rotating the key, shutting subassembly 20 can be switched to the unblock position by the shutting position, thereby accomplish the unblock to centrifugal electron lock core.

It should be noted that, in the process of rotating the driving motor 431, since the driving motor only drives the base 42 to rotate, the driving motor 431 is not affected by the torsional force, so that the lock-up of the driving motor 431 is reduced, and the service life and the safety performance of the lock cylinder can be further improved.

As shown in fig. 3, a side of the main body 411 away from the guide groove 4111 further has a recess 4112, so that the main body 411 is curved. By arranging the main body 411 in an arc shape, resistance of the main body 411 to movement of the driving motor 431 can be effectively reduced, so that motor load can be reduced, and the unlocking process can be accelerated. And damage due to collision between clutch piece 41 and seat 42 can be effectively avoided by this arrangement.

As shown in fig. 1, 4 and 10, the latch assembly 20 includes a latch pin 21 and a first restoring member 22. The locking pin 21 extends along the radial direction of the rear lock core 13, the circumferential side wall of the rear lock core 13 is provided with a mounting hole 131, one end of the locking pin 21 is abutted against the limiting component 30, and the other end of the locking pin 21 can extend into or withdraw from the locking groove 14 through the mounting hole 131; one end of the first restoring member 22 abuts against the latching pin 21, and the other end of the first restoring member 22 abuts against the rear cylinder tube 13, so as to provide a restoring force for the latching pin 21 to extend into the latching groove 14. By means of the arrangement, when the centrifugal electronic lock cylinder is locked, the front lock cylinder 11 is driven to rotate by rotating the key so as to drive the rear lock cylinder 13 to rotate, when the mounting hole 131 of the rear lock cylinder 13 is aligned with the locking groove 14 of the lock shell 10, the locking pin 21 can stretch into the locking groove 14 under the action of the reset force provided by the first reset piece 22, so that the locking component 20 is switched from the unlocking position to the locking position, and the centrifugal electronic lock cylinder is locked.

In one embodiment of the present application, there are two latching pins 21 and two latching grooves 14, and two latching pins 21 are symmetrically disposed and two latching grooves 14 are symmetrically disposed. Through setting up like this, can guarantee effectively that centrifugal electron lock core's performance is more stable.

As shown in fig. 1, 4 and 10, the end of the latching pin 21 protruding into the latching groove 14 is a spherical surface or an arc surface. Through the arrangement, after the clutch block 41 releases the limit of the limit component 30, the rear lock cylinder 13 is rotated through the key, and at the moment, because one end of the locking pin 21 extending into the locking groove 14 is provided with an arc-shaped surface, the locking pin 21 can slide out of the locking groove 14 and extrude the limit component 30 in the rotating process of the rear lock cylinder 13, so that the unlocking of the centrifugal electronic lock cylinder is completed.

As shown in fig. 4, 5, 9 and 10, one end of the latching pin 21 near the limiting component 30 has a first inclined surface 211, the limiting component 30 has a second inclined surface 311 matched with the first inclined surface 211, and the first inclined surface 211 and the second inclined surface 311 are abutted so that the latched component 20 can drive the limiting component 30 to move in the axial direction. With such an arrangement, when the key is turned to make the front core 11 drive the rear core 13 to rotate and make the part of the locking pin 21 extending into the locking groove 14 withdraw from the locking groove 14, the locking pin 21 can extrude the position-limiting component 30 through the cooperation of the first inclined surface 211 and the second inclined surface 311, and the position-limiting component 30 can move towards the front core 11. When the centrifugal electronic lock cylinder is in a locked state, the locking pin 21 can be limited by the limiting component 30 through the matching of the first inclined surface 211 and the second inclined surface 311, so that the locking component 20 is kept in a locked position.

As shown in fig. 1, 4, 5, 9 and 10, the spacing assembly 30 includes a spacing pin 31 and a second restoring member 32.
