Description

Technical Field

[0001] This application relates to the field of lock technology, and in particular to an electronic lock cylinder and a lock cylinder system. Background Technology

[0002] With the development of society and economy and the progress of technology, various electronic lock cylinders have emerged. Among them, some electronic lock cylinders with data interfaces can establish a connection between the data interface and the computer key by inserting a computer key into the slot of the lock cylinder shell. This allows the computer key to verify the identity information of the computer key. When the identity information is verified, the computer key controls the locking module to work, which causes the lock cylinder shell to move in conjunction with the connecting parts under the operation of the locking module. Finally, by turning the computer key, the connecting parts inside the electronic lock cylinder are rotated, which drives the lock pin of the lock body to move, thereby unlocking the lock.

[0003] However, in related technologies, the data interface is usually directly exposed in the slot of the lock cylinder. This means that when the computer key is turned to drive the connecting parts inside the electronic lock cylinder to unlock, the data interface is easily damaged by the torque of the computer key. Summary of the Invention

[0009] The mounting hole has an annular protective wall protruding from the groove of the slot, and the annular protective wall is integrally formed with the bottom of the slot. The annular protective wall is wrapped around the periphery of the data interface and abuts against the computer key when the computer key is inserted into the slot. When locking or unlocking, the annular protective wall bears the torque of the computer key, and the data interface and the computer key maintain electrical connection without torque.

[0010] In some embodiments of this application, a first sealing ring is further provided on the periphery of the data interface, and the first sealing ring is in sealing contact with the inner side of the annular protective wall.

[0011] In some embodiments of this application, the locking module includes a fixed base, a locking tongue assembly, and a control assembly. The fixed base is fixedly installed in the receiving groove, and the boss of the fixed base is exposed in the groove of the receiving groove. The connector is provided with a second rotating groove, and the second rotating groove is sleeved on the boss.

[0012] The boss has a sliding hole along its radial direction and is connected to the second rotating groove. The latch assembly is movably installed in the sliding hole and abuts against the peripheral wall of the second rotating groove. Under the operation of the control component, the movement of the latch assembly is restricted, so that the latch assembly is fixedly abutting against the peripheral wall of the second rotating groove, thereby realizing the linkage between the lock shell and the connector.

[0013] In some embodiments of this application, the peripheral wall of the second rotating groove is recessed with a clutch portion, the latch assembly includes a latch and a spring, the latch is movably mounted in the sliding hole, and the spring is elastically supported between the latch and the hole wall of the sliding hole, so that the latch moves and abuts against the clutch portion, and the control assembly includes a drive member and a locking member, the drive member is convexly connected to the locking member to drive the locking member to lock and engage with the latch, thereby restricting the latch from retracting into the sliding hole.

[0014] In some embodiments of this application, the fixed base is provided with an iron core groove, the iron core groove is connected to one end of the sliding hole away from the peripheral wall of the second rotating groove, the driving member includes a solenoid driver, the locking member is an iron core, and the solenoid driver drives the iron core to be housed in the iron core groove to restrict the movement of the locking tongue.

[0015] In some embodiments of this application, the fixing seat has a connecting portion protruding on the side opposite to the boss, and the connecting portion is fixedly connected to the receiving groove.

[0016] In some embodiments of this application, an annular limiting protrusion is provided on the inner side of the groove at the first end, and the connector is provided with an annular stepped groove that slides in cooperation with the annular limiting protrusion.

[0017] In some embodiments of this application, the peripheral wall of the first rotating groove is provided with a first annular groove, the peripheral side of the lock cylinder is provided with a second annular groove, and the electronic lock cylinder further includes a retaining ring, which is engaged between the first annular groove and the second annular groove to restrict the axial movement of the lock cylinder relative to the lock housing.

[0018] This application also proposes a lock cylinder system, which includes a computer key and an electronic lock cylinder as described in any one of the above claims; wherein...

[0019] The computer key includes a housing and an authorization module. The housing has an unlocking block that is adapted to the slot. The unlocking block has a recessed insertion slot. The authorization module is installed in the housing, and the data plug of the authorization module is disposed in the insertion slot.

[0020] In some embodiments of this application, the peripheral wall of the first rotating groove is recessed with a clearance groove, and the peripheral wall of the slot is provided with a through hole communicating with the first rotating groove. A steel ball is movably disposed in the through hole, and the unlocking block is provided with a locking hole corresponding to the through hole. When the locking hole and the through hole are aligned and the through hole and the clearance groove are misaligned, the steel ball can partially enter the locking hole to restrict the unlocking block from leaving the slot. When the locking hole and the through hole are aligned and the through hole and the clearance groove are aligned, the steel ball can enter the clearance groove through the through hole under the action of external force to exit the locking hole.

[0021] The present invention, through the aforementioned technical solution, features an annular protective wall surrounding the data interface. This allows the data interface to be housed within the space enclosed by the annular protective wall, forming a protective structure around the data interface. Thus, during locking and unlocking, turning the computer key rotates the connecting parts within the electronic lock cylinder to unlock. The annular protective wall provides protection around the data interface, bearing the torque of the computer key. The data interface and computer key maintain an electrical connection without torque, preventing deformation of the data interface due to excessive torque from the computer key. Furthermore, the annular protective wall is integrally formed with the bottom of the slot, allowing the force of the computer key rotating and contacting the annular protective wall to be directly transmitted to the lock cylinder shell, thereby improving torsional strength. Therefore, the technical solution of this application, by forming a protective structure around the data interface with an annular protective wall, improves the torsional strength of the data interface, effectively protecting it from damage when the computer key rotates to unlock the electronic lock cylinder's connecting parts.

[0037] This invention proposes an electronic lock cylinder 10, which can be applied to smart locks for locking and unlocking operations on the lock body. Specifically, it can be applied to the emergency locking / unlocking module of a smart lock. Of course, the electronic lock cylinder 10 can also be applied to the conventional unlocking module of a smart lock. Please refer to the references. Figures 1 to 8 In an embodiment of the present invention, the electronic lock cylinder 10 includes a lock shell 11, a lock cylinder 12, and a connector 13.

[0038] The lock housing 11 is provided with a first rotating groove 111, and the connector 13 is partially or entirely rotatably mounted on the first end of the first rotating groove 111. In some examples, the connector 13 is driven to the lock body in the smart lock so that the rotation of the connector 13 drives the movement of the lock pin of the lock body, causing the lock pin to extend or retract. The fact that part of the connector 13 is mounted on the first end of the first rotating groove 111 is to facilitate the drive connection between the connector 13 and the lock body. Of course, when the connector 13 is fully rotatably mounted on the first end of the first rotating groove 111, the connector 13 can also be exposed in the groove at the first end to facilitate the drive connection between the connector 13 and the lock body. Specifically, the connector 13 can be driven to the lock body through some transmission mechanism, which is not specifically limited in this application.

[0039] The lock cylinder 12 includes a lock cylinder shell 121 and a locking module 122. The lock cylinder shell 121 is rotatably mounted on the second end of the first rotating groove 111 and exposed in the groove opening at the second end. The lock cylinder shell 121 has a receiving groove 1211 and a slot 1212 respectively at opposite ends. The bottom of the slot 1212 has a mounting hole 1213 communicating with the receiving groove 1211.

[0040] The periphery of the lock cylinder shell 121 can rotatably abut against the inner wall of the first rotating groove 111. The lock cylinder shell 121 can also be rotatably mounted on the second end of the first rotating groove 111 via a bearing. It should be emphasized that the computer key 20 is inserted into the slot 1212; therefore, the end of the lock cylinder shell 121 with the slot 1212 is exposed at the opening of the second end. Considering that the lock cylinder shell 121 has a receiving groove 1211 and a slot 1212 at opposite ends, the lock cylinder shell 121 can be manufactured using a one-piece molding process, such as casting or injection molding.

[0041] The locking module 122 is installed in the receiving groove 1211. The data interface 1221 of the locking module 122 passes through the mounting hole 1213. The data interface 1221 is used to connect to the matching computer key 20 so that the computer key 20 controls the operation of the locking module 122, so that the lock cylinder shell 121 is linked with the connector 13 under the operation of the locking module 122. The periphery of the mounting hole 1213 is provided with an annular protective wall 1214 protruding from the groove of the slot 1212. The annular protective wall 1214 is integrally formed with the bottom of the slot 1212. The annular protective wall 1214 is wrapped around the periphery of the data interface 1221 and abuts against the computer key 20 when the computer key 20 is inserted and engaged with the slot 1212. When locking or unlocking, the annular protective wall 1214 bears the torque of the computer key 20, and the data interface 1221 and the computer key 20 are electrically connected without torque.

[0042] The main function of the mounting hole 1213 is to allow the data interface 1221 to pass through. It is understood that the inner side of the annular protective wall 1214 will form an accommodating space 1215 for accommodating the data interface 1221. Preferably, the shapes of the mounting hole 1213 and the inner side of the annular protective wall 1214 are adapted to the data interface 1221. The data interface 1221 includes, but is not limited to, Type-C data interface 1221 and Micro-USB data interface 1221.

[0043] Understandably, in this embodiment, the locking module 122 is installed in the receiving groove 1211 of the lock cylinder shell 121, and the computer key 20 is inserted into the slot 1212 of the lock cylinder shell 121. When the lock cylinder shell 121 is linked with the connector 13 under the operation of the locking module 122, the computer key 20 can be rotated. The computer key 20 abuts against the annular protective wall 1214, which drives the lock cylinder shell 121 and the connector 13 to rotate together. Thus, the lock pin of the lock body is driven by the connector 13 to move, thereby unlocking. When the lock cylinder shell 121 and the connector 13 are not linked, the computer key 20 cannot be rotated to drive the lock cylinder shell 121 and the connector 13 to rotate together, so unlocking cannot be achieved.

[0044] It is important to emphasize that there are multiple ways to implement the connection between the data interface 1221 and the computer key 20, and to control the operation of the locking module 122 via the computer key 20. In one example, the computer key 20 is inserted into the slot 1212, and the data interface 1221 establishes a connection with the computer key 20 to verify the identity information of the computer key 20. When the identity information verification is successful, the computer key 20 controls the locking module 122 to operate. The power required for the operation of the locking module 122 can be obtained from the computer key 20, that is, the locking module 122 can obtain power through the connection between the data interface 1221 and the computer key 20. Alternatively, the power required for the operation of the locking module 122 can be obtained from itself, that is, the locking module 122 includes a battery that stores electrical energy, and the battery can be charged when the data interface 1221 is connected to the computer key 20. Considering the miniaturization of the electronic lock cylinder 10, the preferred solution is that the locking module 122 obtains power through the connection between the data interface 1221 and the computer key 20.

[0045] The present invention, through the above-described technical solution, has an annular protective wall 1214 surrounding the data interface 1221, so that the data interface 1221 is housed in the accommodating space 1215 formed by the annular protective wall 1214. The annular protective wall 1214 forms a corresponding protective structure around the data interface 1221. In this way, when locking or unlocking, turning the computer key 20 drives the connector 13 inside the electronic lock cylinder 10 to rotate and unlock. The annular protective wall 1214 can form protection around the data interface 1221 and withstand the torque of the computer key 20. The data interface 1221 and the computer key 20 maintain an electrical connection without torque, preventing the data interface 1221 from deforming due to excessive torque from the computer key 20. Furthermore, the annular protective wall 1214 is integrally formed with the bottom of the slot 1212. The force of the rotation of the computer key 20 and the annular protective wall 1214 can be directly transmitted to the lock cylinder 12 shell through the annular protective wall 1214 to improve the torsional strength. As can be seen, the technical solution of this application forms a corresponding protective structure on the periphery of the data interface 1221 through the annular protective wall 1214, which can improve the torsional strength of the data interface 1221. When the computer key 20 is turned to drive the connector 13 in the electronic lock cylinder 10 to rotate and unlock, the annular protective wall 1214 can effectively protect the data interface 1221 from being damaged.

[0046] In some examples, such as Figure 2 and Figure 5As shown, a first sealing ring 123 is also provided around the data interface 1221, and the first sealing ring 123 seals against the inner side of the annular protective wall 1214. This arrangement aims to seal the gap between the data interface 1221 and the inner side of the annular protective wall 1214 through the first sealing ring 123, preventing moisture, dust, etc. from the environment from entering the locked interior through the gap between the data interface 1221 and the inner side of the annular protective wall 1214, thereby improving the waterproof and dustproof performance of the electronic lock cylinder 10.

[0047] In some examples, such as Figures 2 to 8 As shown, the locking module 122 includes a fixed base 1222, a latch assembly 1223, and a control component 1224. The fixed base 1222 is fixedly installed in the receiving groove 1211, and the boss 12221 of the fixed base 1222 is exposed in the groove of the receiving groove 1211. The connecting member 13 is provided with a second rotating groove 131, which is sleeved on the boss 12221. The boss 12221 has a sliding hole 12222 along its radial direction, which communicates with the second rotating groove 131. The latch assembly 1223 is movably installed in the sliding hole 12222 and movably abuts against the peripheral wall of the second rotating groove 131. Under the operation of the control component 1224, the movement of the latch assembly 1223 is restricted, so that the latch assembly 1223 is fixedly abuts against the peripheral wall of the second rotating groove 131, thereby realizing the linkage between the lock shell 121 and the connecting member 13.

[0048] The fixing seat 1222 can be fixedly installed in the receiving groove 1211 by welding, riveting or other connection methods, which are not specifically limited here. The boss 12221 of the fixing seat 1222 is exposed in the groove of the receiving groove 1211, which is intended to facilitate the second rotating groove 131 of the connector 13 to be fitted onto the boss 12221; considering that the connector 13 and the lock shell 121 used to fix the fixing seat 1222 are both rotatably set in the first rotating groove 111, the boss 12221 is cylindrical or disc shaped as a whole.

[0049] With this configuration, when the locking module 122 is not working, the bolt assembly 1223 moves against the peripheral wall of the second rotating groove 131. That is, the bolt assembly 1223 can move relative to the peripheral wall of the second rotating groove 131 under external force. At this time, the boss 12221 and the bolt assembly 1223 can rotate relative to the second rotating groove 131 of the connector 13. Thus, when the lock cylinder 12 is subject to external force, it can rotate freely relative to the connector 13, reducing the risk of the data interface 1221 being forcibly rotated by external force. The possibility of damage; when the control component 1224 of the locking module 122 is working, the control component 1224 can restrict the movement of the latch assembly 1223, thereby changing the latch assembly 1223 and the peripheral wall of the second rotating groove 131 from a movable abutment state to a fixed abutment state, that is, the latch assembly 1223 cannot rotate relative to the peripheral wall of the second rotating groove 131 under the action of external force. At this time, the lock shell 121 is linked with the connector 13 by the action of the fixed seat 1222 and the latch assembly 1223.

[0050] In some examples, such as Figures 2 to 8 As shown, the peripheral wall of the second rotating groove 131 is recessed with a clutch portion 132. The latch assembly 1223 includes a latch 12231 and a spring 12232. The latch 12231 is movably mounted in the sliding hole 12222. The spring 12232 is elastically supported between the latch 12231 and the hole wall of the sliding hole 12222, so that the latch 12231 moves against the clutch portion 132. The control assembly 1224 includes a driving member and a locking member. The driving member and the locking member are connected in a transmission manner to drive the locking member to lock the latch 12231, restricting the latch 12231 from retracting into the sliding hole 12222. The clutch portion 132 can be a groove, a recessed hole, etc. The latch 12231 moves against the clutch portion 132 under the elastic force of the spring 12232.

[0051] With this configuration, when the control component 1224 is not working, the locking tongue 12231 can disengage from the clutch part 132 under external force. Of course, when the locking tongue 12231 is aligned with the clutch part 132, the locking tongue 12231 can move and abut against the clutch part 132 under the elastic force of the spring 12232. This reduces the resistance encountered by the lock shell 121 when the connecting member 13 is idling. When the control component 1224 is working, the driving component can quickly drive the locking component to lock with the locking tongue 12231, restricting the locking tongue 12231 from retracting into the sliding hole 12222. This allows the lock shell 121 to be linked with the connecting member 13 by the action of the fixed seat 1222 and the locking tongue component 1223.

[0052] In some examples, such as Figures 2 to 8As shown, the fixed base 1222 is provided with an iron core groove 12223. The iron core groove 12223 is connected to one end of the sliding hole 12222 away from the peripheral wall of the second rotating groove 131. The driving component includes a solenoid driver 12241 and the locking component is an iron core 12242. The solenoid driver 12241 drives the iron core 12242 to be accommodated in the iron core groove 12223 to restrict the movement of the locking tongue 12231.

[0053] With this configuration, when the control component 1224 is not working, the locking tongue 12231 can be disengaged from the clutch part 132 by external force and retract into the iron core groove 12223; of course, when the locking tongue 12231 is aligned with the clutch part 132, the locking tongue 12231 can be disengaged from the iron core groove 12223 by the elastic force of the spring 12232 and move against the clutch part 132. At this time, when the control component 1224 is working, it can quickly drive the iron core 12242 to be housed in the iron core groove 12223 through the solenoid driver 12241, so as to restrict the movement of the locking tongue 12231, so that the lock shell 121 is linked with the connector 13 by the action of the fixed seat 1222 and the locking tongue component 1223.

[0054] In some examples, a second sealing ring 124 is fitted onto the end of the latch 12231 away from the inner groove to further improve the sealing performance of the electronic lock cylinder 10.

[0055] In some examples, the locking module 122 also includes a circuit board that is electrically connected to the data interface 1221 and the solenoid driver 12241, respectively, so as to connect to the computer key 20 through the data interface 1221, obtain the identity information of the computer key 20, verify the identity information, and obtain the electrical energy required for the operation of the locking module 122 when the identity information is verified, and deliver the electrical energy to the solenoid driver 12241, so that the lock cylinder shell 121 is linked with the connector 13 under the operation of the solenoid driver 12241.

[0056] In some examples, such as Figures 2 to 5 As shown, the mounting base 1222 has a connecting portion 12224 protruding on the side opposite to the boss 12221, and the connecting portion 12224 is fixedly connected to the receiving groove 1211. This arrangement is intended to facilitate the fixed connection of the mounting base 1222 to the mounting groove via the connecting portion.

[0057] Specifically, in one example, the connecting part 12224 has a first connecting hole 12225, and the receiving groove 1211 has a second connecting hole 1218 corresponding to the first connecting hole 12225. The first connecting hole 12225 and the second connecting hole 1218 can be fixedly connected by pins or bolts.

[0058] In some examples, the connecting portion 12224 is provided with two opposing support surfaces 12226. The support surfaces 12226 are used for mounting and positioning the aforementioned solenoid driver 12241 to improve the accuracy of the solenoid driver 12241 driving the iron core 12242 to be accommodated in the iron core slot 12223. Preferably, in one example, the locking module 122 further includes a bracket 1225, which is used to mount other components of the locking module 122, such as the solenoid driver 12241, the data interface 1221, etc., to improve the stability of the locking module 122.

[0059] In some examples, the mounting base 1222 is also provided with a third sealing ring 125 on the side opposite to the boss 12221. The third sealing ring 125 is also wrapped around the connecting part 12224 and seals against the lock shell 121.

[0060] In some examples, such as Figure 2 and Figure 5 As shown, an annular limiting protrusion 112 is provided on the inner side of the groove at the first end, and the connector 13 is provided with an annular stepped groove 133 that slides with the annular limiting protrusion 112. This arrangement is intended to facilitate the installation of the connector 13 and the lock cylinder 12 from the second end of the first rotating groove 111 into the first rotating groove 111, and to prevent the connector 13 and the lock cylinder 12 from disengaging from the groove at the first end of the first rotating groove 111. In addition, the connector 13 can be exposed in the groove at the first end, which facilitates the transmission connection between the connector 13 and the lock body.

[0061] In some examples, such as Figure 2 , Figure 3 and Figure 5 As shown, the peripheral wall of the first rotating groove 111 is recessed with a first annular groove 113, and the peripheral side of the lock cylinder 121 is recessed with a second annular groove 1216. The electronic lock cylinder 10 also includes a retaining ring 14, which is engaged between the first annular groove 113 and the second annular groove 1216 to restrict the axial movement of the lock cylinder 121 relative to the lock housing 11. This arrangement aims to prevent the lock cylinder 121 from disengaging from the first rotating groove 111 by restricting its axial movement relative to the lock housing 11, while simultaneously ensuring that the lock cylinder 121 can rotate relative to the lock housing 11.

[0062] This application also proposes a lock cylinder system; please refer to the relevant documentation. Figures 1 to 8 The electronic lock cylinder system includes a computer key 20 and an electronic lock cylinder 10. The specific structure of the electronic lock cylinder 10 is as described in the above embodiments. Since this lock cylinder system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0063] The computer key 20 includes a housing 21 and an authorization module. The housing 21 is provided with an unlocking block 212 that is adapted to the slot 1212. The unlocking block 212 is recessed with a plug groove 213. The authorization module is installed in the housing 21, and the data plug 22 of the authorization module is located in the plug groove 213. When the unlocking block 212 is plugged into the slot 1212, the data interface 1221 is connected to the authorization module through the data plug 22.

[0064] In this embodiment, the periphery of the unlocking block 212 is adapted to the periphery of the slot 1212, and the periphery of the insertion groove 213 is adapted to the periphery of the annular protective wall 1214. When the unlocking block 212 is inserted into the slot 1212, the annular protective wall 1214 is inserted into the insertion groove 213, thereby enabling the data interface 1221 to connect to the authorization module through the data plug 22. After the lock cylinder shell 121 and the connector 13 are linked, turning the computer key 20 causes the lock cylinder shell 121 and the connector 13 to rotate together. The annular protective wall 1214 can effectively protect the data interface 1221 from damage. At the same time, the periphery of the unlocking block 212 can also transmit power by abutting against the periphery of the slot 1212.

[0065] In some examples, such as Figures 2 to 5 As shown, the peripheral wall of the first rotating groove 111 is recessed with a relief groove 114, and the peripheral wall of the slot 1212 is provided with a through hole 1217 communicating with the first rotating groove 111. A steel ball 126 is movably disposed in the through hole 1217. The unlocking block 212 is provided with a locking hole 214 corresponding to the through hole 1217. When the locking hole 214 and the through hole 1217 are aligned, and the through hole 1217 and the relief groove 114 are misaligned, the steel ball 126 can partially enter the locking hole 214 to restrict the unlocking block 212 from disengaging from the slot 1212. When the locking hole 214 and the through hole 1217 are aligned, and the through hole 1217 and the relief groove 114 are aligned, the steel ball 126 can pass through the hole 1217 and enter the relief groove 114 under the action of external force to exit the locking hole 214.

[0066] The number of clearance groove 114, through hole 1217, steel ball 126 and locking hole 214 are corresponding. In some examples, the number of clearance groove 114, through hole 1217, steel ball 126 and locking hole 214 is one.

[0067] This design aims to prevent the computer key 20 from detaching from the electronic lock cylinder 10 during the unlocking process, thus maintaining a stable connection between the computer key 20 and the electronic lock cylinder 10.

[0068] In one example, there are two recessed slots 114, two through holes 1217, two steel balls 126, and two locking holes 214. The two recessed slots 114 are respectively set in the locked and unlocked states of the electronic lock cylinder 10. That is, when the electronic lock cylinder 10 is in the locked and unlocked states, the locking hole 214 is aligned with the through hole 1217, and the through hole 1217 is aligned with the recessed slot 114. At this time, the steel ball 126 can enter the recessed slot 114 through the hole 1217 under the action of external force, so that the computer key 20 can be disengaged from the electronic lock cylinder 10.

[0069] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
