Referring to fig. 1, fig. 2 and fig. 3, the present embodiment provides an intelligent lock cylinder, which can realize electronic unlocking and mechanical unlocking functions.

The intelligent lock core provided by the embodiment comprises a lock shell 200, a cam 300, an electronic lock mechanism 400 and a mechanical lock mechanism 500, wherein two ends of the lock shell 200 are respectively provided with a first accommodating cavity 210 and a second accommodating cavity 220, the middle part of the lock shell 200 is provided with an accommodating groove 230, and the first accommodating cavity 210 and the second accommodating cavity 220 are both penetrated into the accommodating groove 230 by the end part of the lock shell 200 along the length direction of the lock shell 200.

Further, the electronic lock mechanism 400 and the mechanical lock mechanism 500 are respectively disposed at both ends of the lock case 200, wherein the electronic lock mechanism 400 is located in the first accommodating chamber 210, the mechanical lock mechanism 500 is located in the second accommodating chamber 220, and the cam 300 is disposed in the accommodating chamber 230 of the lock case 200 and between the electronic lock mechanism 400 and the mechanical lock mechanism 500.

The idle lock cylinder assembly 520 is in clutch fit with the idle cylinder 510, and a key passage 520a is arranged in the idle lock cylinder assembly 520. Therefore, when the key channel 520a of the idle lock core assembly 520 is not matched with the correct key 100, the idle lock core assembly 520 can idle relative to the idle cylinder 510, the idle cylinder 510 cannot drive the cam 300 to rotate, and when the key channel 520a is inserted into the correct key 100, the idle lock core assembly 520 drives the idle cylinder 510.

Referring to fig. 6 and 7, further, a first rotation stop portion 513 is disposed at an end of the idle rotation cylinder 510 close to the cam 300, and a second rotation stop portion 310 adapted to the first rotation stop portion 513 is disposed at a side of the cam 300 close to the idle rotation cylinder 510, wherein the first rotation stop portion 513 and the second rotation stop portion 310 are in a concave-convex fit structure, so that when the first rotation stop portion 513 is matched with the second rotation stop portion 310, the rotation stop fit of the idle rotation cylinder 510 and the cam 300 can be realized.

Alternatively, the first rotation preventing portion 513 may be provided as a protrusion 5212b and the corresponding second rotation preventing portion 310 may be provided as a groove, or the first rotation preventing portion 513 may be provided as a groove and the corresponding second rotation preventing portion 310 may be provided as a protrusion 5212 b.

Referring to fig. 2, 4, 5 and 8, the idle lock cylinder assembly 520 includes a cylinder module 521 and a clutch module 522, the cylinder module 521 is provided with a key passage 520a adapted to the correct key 100, the clutch module 522 is disposed in the cylinder module 521, and the clutch module 522 is used for realizing the clutch cooperation between the cylinder module 521 and the idle cylinder 510.

The liner module 521 includes a first liner housing 5210 and a blade assembly 5211 disposed in the first liner housing 5210, wherein the first liner housing 5210 is in clearance fit with the idle cylinder 510, and the first liner housing 5210 and the lock housing 200 are axially and doubly limited by the first limit pin 260 and the first limit snap spring 250, so as to prevent the first liner housing 5210 from being separated from the lock housing 200. The blade group 5211 includes a predetermined number of blade single bodies 5212 and a first return spring 5213 disposed on each blade single body 5212, each blade single body 5212 is provided with a first key hole 5212a along the thickness direction for allowing the key 100 to pass through, and the key channel 520a for allowing the key 100 to be inserted is formed between the first key holes 5212a of all the blade single bodies 5212 in the blade group 5211 and the first liner shell 5210.

Further, at least one protrusion 5212b is formed on an inner wall of the first key hole 5212a of each blade unit 5212, wherein the protrusion 5212b corresponds to the unlocking line of the correct key 100 (see fig. 1).

Referring to fig. 4, 5 and 9, the clutch module 522 includes a first clutch plate 5220, a second clutch plate 5221 and a driving spring 5222 disposed in the first container housing 5210. The first clutch plate 5220 is inserted into the first casing 5210 and is located in the middle of the vane assembly 5211, and the first clutch plate 5220 can move along the radial direction of the first casing 5210. The first clutch plate 5220 is provided with clutch teeth 5220a, the first liner housing 5210 is provided with through holes allowing the clutch teeth 5220a to protrude, and the hollow rotating cylinder 510 is provided with first clutch grooves 511 corresponding to the clutch teeth 5220 a. It can be understood that the engaging and disengaging teeth 5220a can be inserted into the first engaging and disengaging groove 511 through a through hole, so as to limit the idle rotation of the bladder module 521 relative to the idle rotation cylinder 510.

The second clutch plate 5221 is disposed at an end of the first clutch plate 5220 away from the clutch teeth 5220a, the second clutch plate 5221 is in linkage engagement with the first clutch plate 5220, and the first container 5210 is provided with a positioning hole 5210a corresponding to the second clutch plate 5221 for accommodating the second clutch plate 5221. The positioning hole 5210a is a long hole, and the limiting hole penetrates through the wall thickness of the first liner casing 5210.

The drive spring 5222 is disposed on the side of the second clutch plate 5221 away from the first clutch plate 5220, and one end of the drive spring 5222 abuts against the inner wall of the idle cylinder 510 and the other end abuts against the second clutch plate 5221. Since the second clutch plate 5221 is coupled to the first clutch plate 5220, the driving spring 5222 can drive the second clutch plate 5221 to drive the first clutch plate 5220 to move along the radial direction of the first casing 5210, so that the clutch teeth 5220a can protrude out of the through hole of the first casing 5210.

Alternatively, the first clutch plates 5220 can be plate-like and the second clutch plates 5221 can be elongated.

The first clutch plate 5220 is provided with a second key hole 5220b in the thickness direction, the second key hole 5220b communicating with the key passage 520a to be a part of the key passage 520a, the second key hole 5220b allowing the correct key 100 to pass therethrough.

Therefore, it can be understood that the second key hole 5220b of the first clutch plate 5220 and the first key hole 5212a of the blade unit 5212 both form a part of the key channel 520a, and further the first clutch plate 5220 can be equivalent to one blade unit 5212, so that in the present embodiment, the arrangement of the first clutch plate 5220 is equivalent to adding one more to the existing number of blade units 5212, and further the number of complex designs of the key 100 (see fig. 1) is increased, and the reliability of the lock is further improved.

Referring to fig. 1, 4, 5, 9 and 10, each of the blade units 5212 of the blade group 5211 has a groove 5212c on a side facing the second clutch plate 5221, and when the correct key 100 is not inserted into the key passage 520a, the grooves 5212c of at least two blade units 5212 of the blade group 5211 are misaligned. Therefore, the vane group 5211 pushes against the second clutch plate 5221, so the driving spring 5222 keeps a compressed state, the second clutch plate 5221 cannot be clamped into the groove 5212c, and the second clutch plate 5221 cannot drive the first clutch plate 5220 to move.

Referring to fig. 1, 4, 5, 9 and 11, when the correct key 100 is inserted into the key passage 520a, the single blade bodies 5212 overcome the urging force of the first return spring 5213, so that the grooves 5212c of all the single blade bodies 5212 in the blade group 5211 are aligned, and the aligned grooves 5212c form second clutch grooves 5212d which are in clutch engagement with the second clutch plate 5221. At this time, the second clutch plate 5221 is engaged in the second clutch groove 5212d under the urging of the driving spring 5222, and at the same time, the first clutch plate 5220 is driven to move in a direction away from the driving spring 5222 along the radial direction of the first liner housing 5210, when the first clutch groove 511 is aligned with the clutch teeth 5220a, the clutch teeth 5220a can be directly inserted into the first clutch groove 511, and then the idle rotation lock liner assembly 520 rotates through the idle rotation cylinder 510 with the cam 300, so as to achieve the unlocking or locking.

When the correct key 100 is pulled out, the first return spring 5213 pushes the vane unit 5212 to return, and the second clutch plate 5221 exits the second clutch groove 5212d under the pushing of the vane unit 5212, so that the clutch teeth 5220a exit the first clutch groove 511, so that the idle lock cylinder assembly 520 is restored to an idle state.

Optionally, a wedge surface 5221a is disposed on a side of the second clutch plate 5221 close to the groove 5212c, and the wedge surface 5221a is adapted to the groove 5212c, so that the second clutch plate 5221 can enter or exit the second clutch groove 5212d more smoothly.

Referring to fig. 1 and 4, in some embodiments, the mechanical lock mechanism 500 further includes an outside door handle 530, and the outside door handle 530 is disposed at an end of the first container case 5210 away from the cam 300.

Referring to fig. 2, 3, 12 and 13, the electronic lock mechanism 400 is in rotation-stop cooperation with the cam 300, and when the electronic lock mechanism 400 obtains an unlocking signal, the electronic lock mechanism 400 can be directly in rotation-stop cooperation with the idle lock cylinder assembly 520, and because the electronic lock mechanism 400 is in rotation-stop cooperation with the cam 300, the idle lock cylinder assembly 520 can be directly driven to rotate, and unlocking and locking can be achieved without the key 100 (see fig. 1).

Specifically, the electronic lock mechanism 400 includes an execution cylinder assembly 410 and a controller 420, the execution cylinder assembly 410 is rotatably disposed in the lock case 200, one end of the execution cylinder assembly 410 is in rotation-stop fit with the cam 300, and the other end of the execution cylinder assembly is connected with the controller 420, when the controller 420 obtains an unlocking signal, the controller 420 can drive the execution cylinder assembly 410 to be directly in rotation-stop fit with the idle cylinder assembly 520.

Further, the actuating cylinder assembly 410 includes a second cylinder shell 411, a linkage seat 412, a linkage pin 413 and a driving member 414, wherein the second cylinder shell 411 is rotatably disposed in the first accommodating cavity 210 of the lock housing 200, and the second cylinder shell 411 and the first accommodating cavity 210 are in clearance fit.

Optionally, the second liner shell 411 and the lock shell 200 are axially limited by a second limiting clamp spring 240, so as to prevent the second liner shell 411 from being removed from the lock shell 200.

Optionally, the actuating cylinder assembly 410 further includes a second limit pin 416, the second limit pin 416 is disposed in the second cylinder 411, and an annular limit groove adapted to the second limit pin 416 is disposed on an inner wall of the first accommodating cavity 210.

Further, in this embodiment, the first limit pin 260 and the second limit pin 416 are respectively provided with a second return spring and a third return spring.

Referring to fig. 2, 7 and 12, the linking base 412 is disposed at an end of the second container shell 411 far away from the controller 420, and is fixedly connected to the second container shell 411, and the linking base 412 is in rotation-stopping fit with the cam 300. Further, a third rotation stopping portion 4120 is disposed on a side of the linkage seat 412 away from the second container shell 411, and a fourth rotation stopping portion 320 adapted to the third rotation stopping portion 4120 is disposed on a side of the cam 300 close to the second container shell 411. Here, the third rotation preventing portion 4120 and the fourth rotation preventing portion 320 have a concave-convex engagement structure, so that the rotation preventing engagement of the interlocking seat 412 and the cam 300 can be performed when the third rotation preventing portion 4120 and the fourth rotation preventing portion 320 are engaged.

Referring to fig. 13, the linking pin 413 is movably disposed on the linking base 412, and further, the linking base 412 is provided with a guide hole, and the linking pin 413 is inserted into the guide hole, so that the linking pin 413 can move along its own axis direction relative to the linking base 412.

The driving member 414 is disposed in the second container 411, and the driving member 414 is connected to the controller 420, and the driving member 414 can drive the linking pin 413 to pass through the cam 300 to directly engage with the idle lock container assembly 520 in a rotation-stopping manner.

Referring to fig. 6 and 7, further, the cam 300 is provided with an avoiding groove 330 for allowing the linkage pin 413 to pass through, and the idle cylinder 510 is provided with an avoiding hole 512 for allowing the linkage pin 413 to pass through, wherein the avoiding groove 330 corresponds to the avoiding hole 512, so that the linkage pin 413 sequentially passes through the avoiding groove 330 and the avoiding hole 512 to be matched with the idle lock cylinder assembly 520.

Referring also to fig. 4, in the present embodiment, an end of the first liner housing 5210 facing the cam 300 is provided with a linking groove 5210b, and when the first liner housing 5210 is rotated until the linking groove 5210b is aligned with the avoiding hole 512, the driving member 414 can drive the linking pin 413 to be inserted into the linking groove 5210b, so that the execution cylinder assembly 410 is locked with the idle cylinder assembly 520. Since the cylinder assembly 410 is engaged with the cam 300 in a rotating manner, the idle cylinder assembly 520 can directly drive the cam 300 to rotate, so as to achieve unlocking and locking. It is understood that the cylinder assembly 410 is automatically reset when the unlocking and locking actions are completed or are not performed within a preset time.

Further, the axis of the linkage pin 413 is not coincident with the rotational axis of the idle cylinder assembly 520, thereby preventing the execution cylinder assembly 410 and the idle cylinder assembly 520 from rotating relatively.

Alternatively, the number of the link pins 413 may be set to two, three, or other numbers, and the number of the drivers 414 corresponds to the link pins 413.

Referring to fig. 4, 12 and 13, the driving member 414 can output a linear motion, and the output end of the driving member 414 is connected to the link pin 413 through a buffer spring 415. As can be appreciated, when the controller 420 obtains the unlock signal and the linking groove 5210b is not aligned with the avoiding hole 512, the driving member 414 drives the linking pin 413 to extend into the avoiding hole 512 to abut against the end surface of the first liner housing 5210, and the buffer spring 415 is compressed, so that the linking pin 413 keeps moving towards the first liner housing 5210 to wait for being inserted into the linking groove 5210 b. When the linking groove 5210b is aligned with the avoiding hole 512, the linking pin 413 is driven by the buffer spring 415 to directly enter the linking groove 5210b to complete the matching, and at this time, the idle lock core assembly 520 is driven to rotate, so that the cam 300 can be driven to rotate. It can be understood that the buffer spring 415 is arranged between the output end of the driving member 414 and the linkage pin 413, and compared with a rigid connection mode, the electronic lock mechanism 400 can avoid faults such as mechanical jamming and the like, and improve reliability.

In this embodiment, the driving member 414 is first driven by a linear motor or an electric push rod. Of course, the screw structure can be driven by a motor.

Further, the controller 420 includes a control unit and a wireless communication unit, the control unit is connected to the wireless communication unit, the wireless communication unit is externally connected to the mobile terminal in a wireless communication manner, for example, connected in a manner of 3G, 4G, 5G, WIFI or bluetooth, and the mobile terminal can send out an unlocking signal.

Optionally, the mobile terminal is a mobile phone or a smart watch.

Referring to fig. 1 and 12, further, the electronic lock mechanism 400 further includes an inner door handle 430, the inner door handle 430 is disposed at an end of the inner cylinder assembly 410 away from the cam 300, the inner door handle 430 is connected to the second cylinder shell 411, and the controller 420 is adjustably disposed on the inner door handle 430.

The embodiment also provides a lockset, which comprises the intelligent lock cylinder provided by the above, wherein the structure of the intelligent lock cylinder is described in detail above and is not described again.

Referring to the drawings, the electronic lock mechanism 400 and the mechanical lock mechanism 500 are integrated on one lock case 200, so that the intelligent lock cylinder has the functions of electronic unlocking and mechanical key 100 unlocking, and a mechanical and electronic dual system is realized.

Further, when the intelligent lock cylinder is installed, the electronic lock mechanism 400 is located inside the door, and the mechanical lock mechanism 500 is located outside the door. Therefore, the electronic lock mechanism 400 or the mechanical lock mechanism 500 can be selected to be unlocked and locked outside the door, when the idle lock cylinder assembly 520 of the mechanical lock mechanism 500 is not matched with the correct key 100, the idle lock cylinder assembly 520 can idle relative to the idle rotary cylinder 510, violent and technical unlocking is avoided, and therefore the anti-theft performance is improved, and the safety is higher. The mechanical lock mechanism 500 can also effectively avoid the problem of failure to unlock due to an abnormality of the electronic lock mechanism 400.

In addition, because the electronic lock mechanism 400 and the mechanical lock mechanism 500 are integrated on the lock shell 200, the whole intelligent lock cylinder has a compact structure and small occupied space, and the whole volume of the lock is favorably reduced so as to ensure the structural strength of the door leaf.
