Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0037] The present invention proposes an electronic lock core 10, which can be used in a smart lock to unlock the lock body of the smart lock. Specifically, it can be used in the emergency unlocking module of the smart lock. Of course, the electronic lock core 10 can also be used in the conventional unlocking module of the smart lock. Figures 1 to 8 In an embodiment of the present invention, the electronic lock core 10 includes a lock housing 11, a lock core 12 and a connecting piece 13.

[0038] The lock housing 11 is provided with a first rotation groove 111, and part or all of the connecting member 13 is rotatably mounted at the first end of the first rotation groove 111. In some examples, the connecting member 13 is connected to the lock body in the smart lock so as to drive the lock pin of the lock body to move by the rotation of the connecting member 13, so that the lock pin extends or retracts, wherein part of the connecting member 13 is installed at the first end of the first rotation groove 111 to facilitate the transmission connection between the connecting member 13 and the lock body. Of course, when the connecting member 13 is fully rotatably mounted at the first end of the first rotation groove 111, the connecting member 13 can also be exposed at the notch at the first end to facilitate the transmission connection between the connecting member 13 and the lock body. Specifically, the connecting member 13 can be connected to the lock body through some transmission mechanisms, which is not specifically limited in this application.

[0039] The lock gall 12 includes a lock gall shell 121 and a locking module 122. The lock gall shell 121 is rotatably installed on the second end of the first rotating groove 111 and exposed at the notch of the second end. The opposite ends of the lock gall shell 121 are respectively provided with a receiving groove 1211 and a slot 1212. The bottom of the slot 1212 is provided with a mounting hole 1213 connected with the receiving groove 1211.

[0040] The peripheral side of the lock shell 121 can directly rotatably abut against the inner wall of the first rotating groove 111, and the lock shell 121 can also be rotatably installed at the second end of the first rotating groove 111 through a bearing. It should be emphasized that the computer key 20 is plugged into the slot 1212, so the lock shell 121 is provided with a notch at one end of the slot 1212 exposed at the second end. Considering that the opposite ends of the lock shell 121 are respectively provided with the receiving groove 1211 and the slot 1212, the lock shell 121 can be made by an integrated molding process, such as a casting process or an injection molding process.

[0041] The locking module 122 is installed in the accommodating groove 1211, and the data interface 1221 of the locking module 122 passes through the installation hole 1213. The data interface 1221 is used to connect the adapted computer key 20 to control the operation of the locking module 122 through the computer key 20, so that the lock shell 121 is linked with the connecting piece 13 under the operation of the locking module 122. The periphery of the installation hole 1213 is protruded with an annular protective wall 1214 facing the notch of the slot 1212, and the annular protective wall 1214 is integrally formed with the bottom of the slot 1212. The annular protective wall 1214 is arranged around the peripheral side of the data interface 1221, and when the computer key 20 is plugged into the slot 1212, it is in transmission contact with the computer key 20; when unlocking, the annular protective wall 1214 bears the torque of the computer key 20, and the data interface 1221 and the computer key 20 remain electrically connected without being subjected to torque.

[0042] Among them, the main function of the mounting hole 1213 is to allow the data interface 1221 to pass through. It can be understood that an accommodating space 1215 for accommodating the data interface 1221 will be formed on the inner side of the annular protective wall 1214. 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, and the data interface 1221 includes but is not limited to a Type-C data interface 1221 and a Micro-USB data interface 1221.

[0043] It can be understood that in the present embodiment, the locking module 122 is installed in the receiving groove 1211 of the lock shell 121, and the computer key 20 is plugged into the slot 1212 of the lock shell 121. When the lock shell 121 is linked with the connecting piece 13 under the operation of the locking module 122, the computer key 20 can be rotated, and the computer key 20 is abutted against the annular protective wall 1214 to drive the lock shell 121 and the connecting piece 13 to rotate together, thereby driving the lock pin of the lock body to move through the connecting piece 13 to achieve unlocking; when the lock shell 121 and the connecting piece 13 are in a non-linked state, the lock shell 121 and the connecting piece 13 cannot be driven to rotate together by rotating the computer key 20, so unlocking cannot be achieved.

[0044] It should be emphasized that the data interface 1221 is connected to the computer key 20, and there are many ways to realize the control of the locking module 122 by the computer key 20. In one example, the computer key 20 is plugged into the slot 1212, and the data interface 1221 is connected to the computer key 20 to verify the identity information of the computer key 20. When the identity information is verified, the computer key 20 controls the locking module 122 to work. The power required for the locking module 122 to work can come 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. The power required for the locking module 122 to work can also come from itself, that is, the locking module 122 includes a battery, which stores power, 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 core 10, the preferred solution is that the locking module 122 can obtain power through the connection between the data interface 1221 and the computer key 20.

[0045] The present invention adopts the above technical scheme, and an annular protective wall 1214 is arranged around the circumference of the data interface 1221, so that the data interface 1221 is accommodated in the accommodating space 1215 formed by the annular protective wall 1214. A corresponding protective structure can be formed on the circumference of the data interface 1221 through the annular protective wall 1214. In this way, when unlocking, the computer key 20 is rotated to drive the connecting piece 13 in the electronic lock core 10 to rotate to achieve unlocking. The annular protective wall 1214 can form protection on the circumference of the data interface 1221. The annular protective wall 1214 withstands the torque of the computer key 20. The data interface 1221 and the computer key 20 are electrically connected without being subjected to torque, thereby preventing the data interface 1221 from being deformed due to excessive torque of the computer key 20. The annular protective wall 1214 is integrally formed with the bottom of the slot 1212. The force of the rotating computer key 20 and the transmission abutment with the annular protective wall 1214 can be directly transmitted to the lock core 12 shell through the annular protective wall 1214 to improve the torsional strength. It can be seen that the technical solution of the present application forms a corresponding protective structure on the surrounding side of the data interface 1221 through the annular protective wall 1214, which can improve the torsional strength of the data interface 1221, so that when the computer key 20 is turned to drive the connecting piece 13 in the electronic lock core 10 to rotate to achieve unlocking, the data interface 1221 can be well protected by the annular protective wall 1214 from being damaged.

[0046] In some examples, such as Figure 2 and Figure 5As shown, a first sealing ring 123 is further provided on the peripheral side of the data interface 1221, and the first sealing ring 123 is in sealing contact with the inner side of the annular protective wall 1214. Such a configuration is intended 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, so as to prevent moisture, dust, etc. in the environment from entering the interior of the lock through the gap between the data interface 1221 and the inner side of the annular protective wall 1214, so as to improve the waterproof and dustproof performance of the electronic lock core 10.

[0047] In some examples, such as Figures 2 to 8 As shown, the locking module 122 includes a fixing seat 1222, a bolt assembly 1223 and a control assembly 1224. The fixing seat 1222 is fixedly mounted on the receiving groove 1211, and the boss 12221 of the fixing seat 1222 is exposed in the notch of the receiving groove 1211. The connecting member 13 is provided with a second rotating groove 131, and the second rotating groove 131 is sleeved on the boss 12221. The boss 12221 is provided with a sliding hole 12222 along its radial direction, and is connected with the second rotating groove 131. The bolt assembly 1223 is movably mounted on the sliding hole 12222 and movably abuts against the peripheral wall of the second rotating groove 131. When the control assembly 1224 is working, the movement of the bolt assembly 1223 is restricted, so that the bolt assembly 1223 is fixedly abutted against the peripheral wall of the second rotating groove 131, so as to realize the linkage between the lock housing 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 with the notch of the receiving groove 1211, which is intended to facilitate the second rotation groove 131 of the connecting member 13 to be sleeved on the boss 12221; considering that the connecting member 13 and the lock shell 121 used for fixing the fixing seat 1222 are both rotatably set in the first rotation groove 111, the boss 12221 is cylindrical or round as a whole.

[0049] With such arrangement, when the locking module 122 is not working, the locking tongue assembly 1223 is movably abutted against the peripheral wall of the second rotating groove 131, that is, the locking tongue assembly 1223 can be moved relative to the peripheral wall of the second rotating groove 131 under the action of external force. At this time, the boss 12221 and the locking tongue assembly 1223 can rotate relative to the second rotating groove 131 of the connecting member 13. In this way, when the lock core 12 is subjected to external force, it can idle relative to the connecting member 13, reducing the risk of the data interface 1221 being forced to rotate by external force. and the possibility of damage; when the control component 1224 of the locking module 122 is working, the control component 1224 can limit the movement of the lock tongue component 1223, so that the lock tongue component 1223 and the peripheral wall of the second rotating groove 131 are transformed from a movable abutment state to a fixed abutment state, that is, the lock tongue component 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 acted upon by the fixed seat 1222 and the lock tongue component 1223 and is linked to the connecting member 13.

[0050] In some examples, such as Figures 2 to 8 As shown, the peripheral wall of the second rotating groove 131 is concavely provided with a clutch portion 132, the locking tongue assembly 1223 includes a locking tongue 12231 and a spring 12232, the locking tongue 12231 is movably mounted in the sliding hole 12222, the spring 12232 is elastically supported between the locking tongue 12231 and the hole wall of the sliding hole 12222, so that the locking tongue 12231 is movably in contact with the clutch portion 132, and the control assembly 1224 includes a driving member and a locking member, the driving member is in transmission connection with the locking member, so as to drive the locking member to lock and cooperate with the locking tongue 12231, and limit the locking tongue 12231 to retreat to the sliding hole 12222. The clutch portion 132 can be a groove, a concave hole, etc., and the locking tongue 12231 is movably in contact with the clutch portion 132 under the elastic force of the spring 12232.

[0051] With such arrangement, when the control component 1224 is not working, the lock tongue 12231 can be separated from the clutch part 132 by external force. Of course, when the lock tongue 12231 is aligned with the clutch part 132, the lock tongue 12231 can be movably abutted against the clutch part 132 by the elastic force of the spring 12232, thereby reducing the resistance encountered by the lock shell 121 when the connecting member 13 is idling, and when the control component 1224 is working, the driving member can quickly drive the locking member to lock and cooperate with the lock tongue 12231, limiting the lock tongue 12231 from retreating to the sliding hole 12222, so that the lock shell 121 is linked to the connecting member 13 by the action of the fixed seat 1222 and the lock tongue assembly 1223.

[0052] In some examples, such as Figures 2 to 8As shown, the fixed seat 1222 is provided with an iron core groove 12223, and 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, and the driving member includes a solenoid driver 12241, and the locking member is an iron core 12242. The solenoid driver 12241 drives the iron core 12242 to be accommodated in the iron core groove 12223 to limit the movement of the locking tongue 12231.

[0053] With such arrangement, when the control component 1224 is not working, the lock tongue 12231 can be separated from the clutch part 132 by external force and retreat to the iron core groove 12223; of course, when the lock tongue 12231 is aligned with the clutch part 132, the lock tongue 12231 can be separated from the iron core groove 12223 by the elastic force of the spring 12232 and movably abut against the clutch part 132. At this time, the control component 1224 can work quickly to drive the iron core 12242 to be accommodated in the iron core groove 12223 through the solenoid driver 12241 to limit the movement of the lock tongue 12231, so that the lock shell 121 is acted upon by the fixed seat 1222 and the lock tongue component 1223 and is linked with the connecting member 13.

[0054] In some examples, a second sealing ring 124 is sleeved on one end of the lock tongue 12231 away from the close groove to further improve the sealing performance of the electronic lock core 10 .

[0055] In some examples, the locking module 122 also includes a circuit board, which 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, and verify the identity information, and obtain the electric energy required for the locking module 122 to work when the identity information verification is passed, and transmit the electric energy to the solenoid driver 12241, so that the lock 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 fixing seat 1222 is provided with a connecting portion 12224 on one side away from the boss 12221, and the connecting portion 12224 is fixedly connected to the receiving groove 1211. Such a configuration is intended to facilitate the fixing seat 1222 to be fixedly connected to the mounting groove through connection.

[0057] Specifically, in one example, the connecting portion 12224 is provided with a first connecting hole 12225 , and the receiving groove 1211 is provided with 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 connection portion 12224 is provided with two supporting surfaces 12226 arranged opposite to each other, and the supporting surfaces 12226 are used to install and position the solenoid driver 12241 mentioned above, so as to improve the accuracy of the solenoid driver 12241 driving the iron core 12242 to be accommodated in the iron core slot 12223.
