[0009] In some embodiments of the present application, the clutch assembly is provided with a first clutch part at one end away from the driving piece, and the dial block assembly is provided with a second clutch part at one end facing the first clutch part. The first clutch part and the second clutch part abut against each other and are in mutual embedded contact or abutting contact under the driving of the driving piece, so that the clutch assembly moves back and forth along the axial direction.

[0010] After authorization is obtained, the control assembly limits the axial movement of the clutch assembly, so that the first clutch part and the second clutch part remain in the state of mutual embedded contact. The driving piece is in transmission connection with the dial block assembly through the clutch assembly.

[0011] In some embodiments of the present application, the clutch assembly comprises a clutch piece and an elastic piece.

[0013] In some embodiments of the present application, the elastic piece comprises a spiral spring, one end of the spiral spring elastically abuts against the bottom wall of the plug-in slot, and the other end of the spiral spring elastically abuts against the driving column.

[0014] In some embodiments of the present application, the clutch piece also slidably abuts against the slot wall of the mounting slot.

[0015] In some embodiments of the present application, the circumferential side of the clutch piece is recessed with an annular groove, the authorization piece is elastically mounted in the connecting hole and is in plug-in cooperation with the annular groove under the action of elastic force. After authorization is obtained, the control assembly limits the authorization piece from retreating in the connecting hole, so that the authorization piece is in plug-in cooperation with the annular groove to limit the axial movement of the clutch piece.

[0016] In some embodiments of the present application, the first clutch part comprises a V-shaped protrusion, and the second clutch part comprises a V-shaped matching groove matched with the V-shaped protrusion.

[0021] The lock cylinder provided in this application embodiment, through the above-described structural design, prevents its control component from entering the mounting slot via the connecting hole and cooperating with the clutch component to restrict the axial movement of the clutch component when unauthorized. In other words, without authorization, the clutch component can move axially. At this time, when the clutch component is driven to rotate by the drive component, it will move back and forth axially due to elastic force and the interaction force with the toggle component, unable to transmit power to the toggle component. Therefore, the drive component cannot drive the toggle component to rotate through the clutch component. Thus, the technical solution of this application, when unauthorized, allows the drive component to rotate under external force, but does not transmit power to the toggle component; the drive component only idles, effectively protecting the lock cylinder structure from violent damage.

[0035] The embodiments of the present application provide a lock cylinder 100, which can be applied to a smart door lock. The smart door lock with the lock cylinder 100 can be applied to home, office and the like. Please refer to Figures 1 to 5 In the embodiments of the present application, the lock cylinder 100 includes a lock cylinder 100 assembly and an authorization module 20.

[0036] The lock cylinder 100 assembly includes a housing 11, a driving member 12, a clutch assembly 13 and a dial block assembly 14. The housing 11 is provided with a mounting groove 111 and a connecting hole 112 in communication with the inner wall of the peripheral side of the mounting groove 111. The driving member 12 is rotatably installed in the mounting groove 111 and partially exposed outside the mounting groove 111. The dial block assembly 14 is rotatably installed in the housing 11 and partially located in the mounting groove 111. The dial block assembly 14 is used to drive the lock body 300 of the smart door lock to perform unlocking and locking operations on the lock body 300. One end of the clutch assembly 13 is elastically installed on the driving member 12. The other end of the clutch assembly 13 elastically abuts against the dial block assembly 14 and is driven by the elastic force and the interaction force of the dial block assembly 14 under the driving of the driving member 12 to move back and forth along the axial direction.

[0037] The driving member 12 can also be named as a handle. The part of the driving member 12 exposed outside the mounting groove 111 is mainly used for user operation, i.e. for user to hold and drive the driving member 12 to rotate to realize the unlocking and locking operation on the lock body 300.

[0038] In order to improve the operation feeling of the user on the driving member 12, the driving member 12 can be rotatably installed in the mounting groove 111 through a bearing. Similarly, the dial block assembly 14 can also be rotatably installed in the mounting groove 111 through a bearing. Of course, in some examples, the driving member 12 and the dial block assembly 14 can also be directly in slidable contact with the groove wall of the mounting groove 111.

[0039] One end of the clutch assembly 13 is elastically mounted to the driving member 12, and the other end is in abutment with the knob assembly 14, that is, the clutch assembly 13 is movably arranged between the driving member 12 and the knob assembly 14, and the clutch assembly 13 can move axially under the action of external force between the driving member 12 and the knob assembly 14. It should be emphasized that one end of the clutch assembly 13 is elastically mounted to the driving member 12, and under the action of elastic force, the clutch assembly 13 will have a tendency to move away from the driving member 12, so that the end of the clutch assembly 13 away from the driving member 12 is in abutment with the knob assembly 14, that is, the clutch assembly 13 is in elastic abutment with the knob assembly 14, so that the clutch assembly 13 and the knob assembly 14 always remain in contact with each other.

[0040] When the clutch assembly 13 rotates relative to the knob assembly 14, the parts of the clutch assembly 13 and the knob assembly 14 in contact with each other will interact, causing the clutch assembly 13 and the knob assembly 14 to partially separate from each other, so that the clutch assembly 13 moves axially towards the driving member 12.

[0041] The authorization module 20 is mounted to the housing 11, and the authorization module 20 includes a movably arranged authorization member 21 and a control assembly 22. After authorization, the control assembly 22 controls the authorization member 21 to enter the mounting groove 111 through the connecting hole 112, cooperate with the clutch assembly 13, limit the axial movement of the clutch assembly 13, so that the clutch assembly 13 and the knob assembly 14 are fixedly in abutment, and the driving member 12 is drivingly connected with the knob assembly 14 through the clutch assembly 13.

[0042] The authorization module 20 usually has one or more electronic component modules for identity information verification, and the control assembly 22 can be authorized only when the identity verification is passed. Among them, the user can establish a communication connection with the authorization module through wireless connection such as Bluetooth to verify the identity information.

[0043] It should be emphasized that in some examples, before the control assembly 22 is authorized, the authorization member 21 may, under the action of elastic force or other external force, enter the mounting groove 111 through the connecting hole 112 and cooperate with the clutch assembly 13, but because the control assembly 22 is not authorized, the cooperation of the authorization member 21 and the clutch assembly 13 will not limit the axial movement of the clutch assembly 13, and will not cause the clutch assembly 13 and the knob assembly 14 to be fixedly in abutment, so the driving member 12 cannot be drivingly connected with the knob assembly 14 through the clutch assembly 13.

[0044] When the lock cylinder 100 is unlocked, the user establishes a communication connection with the authorization module 20 through an external device to verify the identity information. When the identity verification is passed, the control component 22 is authorized, the control authorization piece 21 enters the installation slot 111 through the connecting hole 112, cooperates with the clutch assembly 13, restricts the axial movement of the clutch assembly 13, and makes the clutch assembly 13 and the dial block assembly 14 fixedly abut. At this time, the driving piece 12 drives the clutch assembly 13 to rotate, and the clutch assembly 13 can transmit power to the dial block assembly 14 through the fixed abutment, and drive the dial block assembly 14 to rotate, and then realize the unlocking operation of the lock body 300 through the dial block assembly 14.

[0045] The lock cylinder 100 provided by the embodiment of the application is provided with the above structure. When the control component 22 is not authorized, the control authorization piece 21 cannot enter the installation slot 111 through the connecting hole 112 to cooperate with the clutch assembly 13 to restrict the axial movement of the clutch assembly 13. That is, when the control component 22 is not authorized, the clutch assembly 13 can move axially. At this time, the driving piece 12 drives the clutch assembly 13 to rotate. The clutch assembly 13 moves back and forth along the axial direction under the action of the elastic force and the interaction force with the dial block assembly 14, and cannot transmit power to the dial block assembly 14. That is, the driving piece 12 cannot drive the dial block assembly 14 to rotate through the clutch assembly 13. It can be seen that, when the control component 22 is not authorized, the driving piece 12 can drive the clutch assembly 13 to rotate under the action of an external force, but cannot transmit power to the dial block assembly 14. That is, the driving piece 12 only idles, which can well protect the structure of the lock cylinder 100 from being damaged by violence.

[0046] In some examples, as shown in Figures 2 to 5 The end of the clutch assembly 13 away from the driving piece 12 is provided with a first clutch part 1311, and the end of the dial block assembly 14 towards the first clutch part 1311 is provided with a second clutch part 1411. The first clutch part 1311 abuts against the second clutch part 1411 and is in mutual embedded contact or abutting contact with the second clutch part 1411 under the driving of the driving piece 12, so that the clutch assembly 13 moves back and forth along the axial direction. After the control component 22 is authorized, the axial movement of the clutch assembly 13 is restricted, so that the first clutch part 1311 and the second clutch part 1411 remain in the state of mutual embedded contact. The driving piece 12 is in driving connection with the dial block assembly 14 through the clutch assembly 13.

[0047] It should be emphasized that one end of the clutch assembly 13 is elastically mounted to the driving piece 12. Under the action of the elastic force, the clutch assembly 13 has a tendency to move towards the direction away from the driving piece 12. In this way, the first clutch part 1311 and the second clutch part 1411 elastically abut against each other, so that the first clutch part 1311 and the second clutch part 1411 always remain in mutual contact.

[0048] It can be understood that the first clutch part 1311 and the second clutch part 1411 are arranged in a concave-convex manner, when the concave-convex parts of the first clutch part 1311 and the second clutch part 1411 are aligned with each other, the first clutch part 1311 and the second clutch part 1411 are in a mutual embedded contact state, and when the concave-convex parts of the first clutch part 1311 and the second clutch part 1411 are misaligned with each other, the first clutch part 1311 and the second clutch part 1411 are in a mutual abutting contact state. The mutual abutting contact state of the first clutch part 1311 and the second clutch part 1411 refers to the state that the top end or end face of the first clutch part 1311 farthest away from the driving member 12 abuts against the top end or end face of the second clutch part 1411 closest to the driving member 12. When the first clutch part 1311 and the second clutch part 1411 switch from the mutual embedded contact state to the mutual abutting contact state, the clutch assembly 13 moves along the axial direction thereof towards the driving member 12 under the interaction force between the first clutch part 1311 and the second clutch part 1411; when the first clutch part 1311 and the second clutch part 1411 switch from the mutual abutting contact state to the mutual embedded contact state, the clutch assembly 13 moves along the axial direction thereof away from the driving member 12 under the interaction force between the first clutch part 1311 and the second clutch part 1411 and the elastic force.

[0049] In this way, the first clutch part 1311 and the second clutch part 1411 are kept in the mutual embedded contact state, the driving member 12 drives the clutch assembly 13 to rotate, the clutch assembly 13 can transmit power through the mutual embedded contact between the first clutch part 1311 and the second clutch part 1411, and drive the dial block assembly 14 to rotate, and then the dial block assembly 14 realizes the unlocking operation on the lock body 300; when the control assembly 22 is not authorized, the clutch assembly 13 can move along the axial direction thereof, at this time, the driving member 12 drives the clutch assembly 13 to rotate, the clutch assembly 13 moves back and forth along the axial direction thereof under the interaction force between the first clutch part 1311 and the second clutch part 1411 and the elastic force, the first clutch part 1311 and the second clutch part 1411 switch back and forth between the mutual embedded contact state and the mutual abutting contact state, and the power cannot be transmitted to the dial block assembly 14, that is, the driving member 12 cannot drive the dial block assembly 14 to rotate through the clutch assembly 13.

[0050] In some examples, the clutch assembly 13 is provided with a first ratchet structure at one end away from the driving member 12, the knob 142 assembly 14 is provided with a second ratchet structure at one end towards the first ratchet structure, the first ratchet structure and the second ratchet structure elastically abut and are in mesh or disengaged with each other under the driving of the driving member 12, so that the clutch assembly 13 moves back and forth along the axial direction. After authorization, the control assembly 22 limits the axial movement of the clutch assembly 13, so that the first ratchet structure and the second ratchet structure remain in mesh with each other, and the driving member 12 is in driving connection with the knob 142 assembly 14 through the clutch assembly 13.

[0051] In some examples, as shown in Figures 3 to 5 The clutch assembly 13 includes a clutch member 131 and an elastic member 132, the clutch member 131 is in driving connection with the driving member 12 through plug-in fitting, and the elastic member 132 is elastically installed between the clutch member 131 and the driving member 12. In this way, the driving connection between the driving member 12 and the clutch member 131 is simple, which can improve the reliability of transmission, and the installation of the elastic member 132 is simple.

[0052] In other examples, the side of the driving member 12 towards the clutch member 131 is provided with a semi-cylinder, the side of the clutch member 131 towards the driving member 12 is provided with a semi-cylinder, the two semi-cylinders abut each other and combine to form a complete cylinder, and the elastic member 132 is a sleeve spring which is sleeved on the circumferential side of the cylinder and elastically abuts one end of the sleeve spring with the driving member 12 and the other end of the sleeve spring with the clutch member 131.

[0053] In some examples, as shown in Figure 3 and Figure 4 The clutch member 131 is provided with a plug-in slot 1312, the slot wall of the plug-in slot 1312 is provided with a matching surface, the side of the driving member 12 towards the clutch member 131 is provided with a driving column 121, the circumferential side of the driving column 121 is provided with a driving surface, the driving column 121 is in plug-in fitting with the plug-in slot 1312, and the driving surface abuts and matches with the matching surface. In this way, the reliability of transmission between the driving member 12 and the clutch member 131 is further improved.

[0054] Specifically, in the example shown in Figure 3 The driving column 121 is a quadrangular prism, the circumferential side of the quadrangular prism is provided with four driving surfaces, and the plug-in slot 1312 is matched with the quadrangular prism. In other examples, the driving column 121 can be a triangular prism, a pentagonal prism, etc.

[0055] In other examples, the driving member 12 is provided with a plug-in slot 1312, the slot wall of the plug-in slot 1312 is provided with a matching surface, the side of the clutch member 131 towards the driving member 12 is provided with a driving column 121, the circumferential side of the driving column 121 is provided with a driving surface, the driving column 121 is in plug-in fitting with the plug-in slot 1312, and the driving surface abuts and matches with the matching surface.

[0056] In some examples, as shown in Figures 3 to 5 The elastic member 132 includes a coil spring, one end of which elastically abuts against the bottom wall of the insertion slot 1312, and the other end of which elastically abuts against the driving column 121. Such arrangement is intended to facilitate the installation of the coil spring, and the coil spring is not easily removed due to the limitation of the slot wall of the insertion slot 1312. Meanwhile, the coil spring is usually a standard part that can be directly purchased on the market, so as to reduce the manufacturing cost of the lock cylinder 100.

[0057] Of course, in some examples, the coil spring can be sleeved on the driving column 121, one end of the coil spring elastically abuts against the slot of the insertion slot 1312, and the other end of the coil spring elastically abuts against the driving member 12.

[0058] In some examples, as shown in Figure 4 and Figure 5 The clutch member 131 also slidably abuts against the slot wall of the mounting slot 111. Such arrangement is intended to facilitate the axial sliding of the clutch member 131 along the slot wall of the mounting slot 111, and also facilitate the rotation of the clutch member 131 along the slot wall of the mounting slot 111, so as to improve the stability of the clutch member 131 during movement.

[0059] In some examples, as shown in Figures 3 to 5 The circumferential side of the clutch member 131 is recessed with an annular groove 1313, the authorized member 21 is elastically installed in the connecting hole 112 and is in insertion fit with the annular groove 1313 under the action of the elastic force, and the control assembly 22 limits the authorized member 21 from retreating in the connecting hole 112 after authorization, so that the authorized member 21 is in insertion fit with the annular groove 1313 to limit the axial movement of the clutch member 131.

[0060] Such arrangement is intended to facilitate the insertion fit of the authorized member 21 with the annular groove 1313 under the action of the elastic force, but the authorized member 21 can retreat in the connecting hole 112 due to the external force, so it does not limit the axial movement of the clutch member 131. Therefore, when the identity verification is passed, the control assembly 22 can quickly control the authorized member 21 to limit the axial movement of the clutch member 131, so as to improve the efficiency of unlocking.

[0061] In some examples, the control assembly 22 includes a driver and a locking member, the driver and the locking member are in transmission connection, and the driver drives the locking member to abut against one end of the authorized member 21 away from the clutch member 131 to limit the authorized member 21 from retreating in the connecting hole 112 after authorization.

[0062] In some examples, as shown in Figures 3 to 5As shown, the first clutch portion 1311 comprises a V-shaped protrusion, and the second clutch portion 1411 comprises a V-shaped matching groove matched with the V-shaped protrusion. When the first clutch portion 1311 and the second clutch portion 1411 are in mutual alignment, the V-shaped protrusion is embedded in the V-shaped matching groove, and when the first clutch portion 1311 and the second clutch portion 1411 are in mutual misalignment, the top end of the V-shaped protrusion abuts against the end face where the groove opening of the V-shaped matching groove is located.

[0063] In some examples, the first clutch portion 1311 comprises a plurality of hemispherical protrusions, and the second clutch portion 1411 is provided with an abutting face recessed with a plurality of hemispherical recesses matched with the plurality of hemispherical protrusions. When the first clutch portion 1311 and the second clutch portion 1411 are in mutual alignment, the hemispherical protrusions are embedded in the hemispherical recesses, and when the first clutch portion 1311 and the second clutch portion 1411 are in mutual misalignment, the top end of the hemispherical protrusions abuts against the abutting face.

[0064] In some examples, as shown, Figures 1 to 5 As shown, the dial block assembly 14 comprises a rotating shaft 141 and a dial block 142, the rotating shaft 141 is rotatably installed in the installation groove 111, and the dial block 142 is fixedly connected to one end of the rotating shaft 141. The dial block 142 is used to drive the lock body 300 of the intelligent door lock to perform unlocking and locking operations on the lock body 300. In this way, the rotating shaft 141 is more stable during rotation, and the reliability of the dial block 142 driving the lock body 300 of the intelligent door lock is improved.

[0065] It can be understood that the second clutch portion 1411 mentioned above is arranged at the end of the rotating shaft 141 away from the dial block 142.

[0066] Please refer to Figures 1 to 6 The present application also provides an intelligent door lock, which comprises an emergency power supply module 200 and a lock cylinder 100. The specific structure of the lock cylinder 100 is referred to the above-mentioned embodiments. Since the intelligent door lock adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.
