[0040] The utility model proposes a lock core 10, which is applied to a smart lock and is used to unlock the lock body of the smart lock. Figures 1 to 3 and Figure 6 In the embodiment of the utility model, the lock core 10 includes a control component 11 and a locking module 12 .

[0041] The control component 11 includes a data connector 111 and a controller 112 that are compatible with the data interface of the mobile phone. The data connector 111 is used to collect the identity information of the mobile phone and obtain the electrical energy required for the locking module 12 to work. The locking module 12 is electrically connected to the controller 112. The controller 112 also controls the locking module 12 to work according to the identity information, so that the lock body is unlocked under the operation of the locking module 12.

[0042] The data connector 111 is mainly used to cooperate with the data interface of the mobile phone, so the data connector 111 should be adapted to the mainstream mobile phone data interface on the market, including but not limited to Type-C data connector 111 and Micro USB data connector 111. The data interface can be hidden in the smart lock when not in use, and the data interface is exposed only when it is needed, so as to reduce the exposure time of the data interface to the environment and avoid affecting the metal pins in the data interface.

[0043] When the lock core 10 is used, the data connector 111 cooperates with the data interface of the mobile phone, and the data interface collects the operator's mobile phone identity information. When the collected identity information matches the pre-set identity information, the controller 112 controls the locking module 12 to operate, so that the lock body is unlocked under the operation of the locking module 12.

[0044] Among them, there are multiple ways for the lock body to perform unlocking operations under the operation of the locking module 12. In one way, the locking module 12 uses the electric energy obtained from the data connector 111 to directly drive the lock body to perform an unlocking operation. In another setting, the locking module 12 includes a handle and a smart lock core 10, and the handle is connected to the lock body. The controller 112 controls the smart lock core 10 to lock or unlock the handle, limit the operation of the handle on the lock body, or remove the restriction on the operation of the handle on the lock body, thereby performing an indirect unlocking operation.

[0045] Through the above technical solution, the user can use the data interface of the mobile phone to connect with the data connector 111 to realize the identity information verification with the lock core 10, and provide the power required for the locking module 12 to work, so that the controller 112 can control the locking module 12 to work, so that the lock body can perform the unlocking operation under the work of the locking module 12. In this way, the user does not need to use a mechanical key, but uses the mobile phone carried with him to connect with the data connector 111 of the lock core 10, so that the identity information can be verified and the power required for the locking module 12 to work can be provided through the mobile phone to control the locking module 12, so that the lock body completes the unlocking operation, thereby improving the convenience and reliability of the lock core 10. At the same time, since the unlocking operation can be realized without a key, the manufacturing cost of the smart lock is reduced.

[0046] In some examples, such as Figures 2 to 4 As shown, the lock core 10 also includes a lock tube 13, which is provided with a first accommodating groove 131, and the locking module 12 is rotatably installed in the first accommodating groove 131; the locking module 12 includes a first driving device 121, a driving component 122 and a locking structure 123, and the locking structure 123 is movably installed in the driving component 122, and the first driving device 121 acts on the locking structure 123 to lock or unlock the locking module 12 and the lock tube 13 through the locking structure 123; when the locking module 12 and the lock tube 13 are unlocked, the locking module 12 can rotate relative to the lock tube 13 under the action of external force, so as to drive the driving component 122 to rotate through the locking module 12 to act on the lock body, so that the lock body is unlocked.

[0047] There are many ways for the first driving device 121 to act on the locking structure 123. In one way, the first driving device 121 directly drives the locking structure 123 to move, so that the locking structure 123 abuts against the lock tube 13 or is plugged into the limiting hole on the lock tube 13, limiting the relative movement of the locking module 12 and the lock tube 13, locking the locking module 12 and the lock tube 13, and the unlocking principle is similar to the above and will not be repeated one by one. In another way, the locking structure 123 is elastic and elastically abuts against the lock tube 13. When the first driving device 121 acts on the locking structure 123, the driving device limits the elastic movement of the locking structure 123, thereby locking the locking module 12 and the lock tube 13. When the first driving device 121 does not act on the locking structure 123, since the locking structure 123 elastically abuts against the lock tube 13, when the locking module 12 moves relative to the lock tube 13, the lock tube 13 can elastically squeeze the locking structure 123.

[0048] In this configuration, the first drive device 121 acts on the locking structure 123 to lock or unlock the locking module 12 and the lock tube 13 through the locking structure 123, thereby indirectly controlling the operation of the locking module 12 on the lock body by locking or unlocking the locking module 12 and the lock tube 13. Therefore, the locking module 12 does not need to obtain a large amount of electric energy to drive the unlocking operation of the lock body. When the locking module 12 and the lock tube 13 are unlocked, the user applies an external force to the locking module 12 to drive the driving component 122 to rotate, so as to act on the lock body, so that the lock body performs the unlocking operation. The driving device can operate normally even when the output power of the driving device is low, so the first driving device 121 can be designed to be miniaturized, while reducing the load on the mobile phone power supply.

[0049] In some examples, such as Figures 2 to 4 As shown, the first driving device 121 includes a first motor 1211 and a push piece 1212, and the first motor 1211 is transmission-connected with the push piece 1212 to drive the push piece 1212 to movably abut or movably separate from the locking structure 123, wherein when the push piece 1212 movably abuts against the locking structure 123 to restrict the movement of the locking structure 123, the locking structure 123 locks the locking module 12 and the locking tube 13; when the push piece 1212 movably separates from the locking structure 123 to release the restriction on the locking structure 123, the locking structure 123 unlocks the locking module 12 and the locking tube 13.

[0050] There are many ways to connect the first motor 1211 to the push member 1212. In one way, the push member 1212 has an inclined surface, and the first motor 1211 drives the push member 1212 to reciprocate along a straight line, so that the push member 1212 can be movably connected to or separated from the locking structure 123 through the inclined surface. In another way, the push member 1212 has a cantilever 1213, and the first motor 1211 drives the push member 1212 to rotate, so that the push member 1212 can be movably connected to or separated from the locking structure 123 through the cantilever 1213.

[0051] In this way, the first motor 1211 can directly drive the push piece 1212 to move so that the push piece 1212 and the locking structure 123 are movably connected or movably separated, thereby limiting the movement of the locking structure 123 or releasing the restriction on the locking structure 123. In this way, the push piece 1212 is utilized to realize that the locking structure 123 unlocks or locks the locking module 12 and the lock tube 13, thereby indirectly controlling the operation of the locking module 12 on the lock body.

[0052] In some examples, such as Figures 2 to 4 As shown, the locking module 12 also includes a first lock core shell 124, the first lock core shell 124 is provided with a first mounting groove 1241, the first motor 1211 is fixedly installed in the first mounting groove 1241, and the push-up member 1212 is rotatably installed in the first mounting groove 1241. A cantilever 1213 is protruded from the side of the push-up member 1212 away from the first motor 1211, and the cantilever 1213 is also extended along the axis of rotation of the push-up member 1212 in the direction away from the first motor 1211, and is also spaced from the axis. The cantilever 1213 is movably connected to or separated from the locking structure 123.

[0053] With such arrangement, when the first motor 1211 drives the resisting member 1212 to rotate, the resisting member 1212 rotates more smoothly, thereby improving the reliability of the operation of the first motor 1211 and thus improving the stability of the operation of the locking module 12 .

[0054] In some examples, such as Figures 2 to 5 As shown, the driving assembly 122 is provided with a sliding hole 1223; the locking structure 123 includes a locking pin 1231 and a spring 1232, the locking pin 1231 includes a locking end and a locking rod, the spring 1232 is sleeved on the locking rod, one end of the spring 1232 elastically abuts against a side of the locking end close to the locking rod, and the other end of the spring 1232 elastically abuts against the hole wall of the sliding hole 1223 to elastically support the locking pin 1231;

[0055] The groove wall of the first accommodating groove 131 is recessed with a locking pit 132 that cooperates with the locking end. The first motor 1211 drives the abutment 1212 to rotate to drive the cantilever 1213 to flexibly abut or flexibly separate from the end of the locking rod away from the locking end, and the locking module 12 and the locking tube 13 are locked or unlocked through the cooperation between the locking end and the locking pit 132.

[0056] In this embodiment, the side of the locking end that cooperates with the locking pit 132 is spherical, and the edge of the locking pit 132 is arc-shaped, so that the locking end can enter or exit the locking pit 132, thereby improving the smoothness of the rotation of the driving component 122.

[0057] With such arrangement, after the cantilever 1213 is movably separated from the locking rod, the locking pin 1231 elastically supported by the spring 1232 in the sliding hole 1223 can smoothly allow the locking end to enter or exit the locking pit 132, so as to facilitate the rotation of the abutment 1212, thereby driving the cantilever 1213 to movably abut against the end of the locking rod away from the locking end, thereby improving the operating efficiency of the lock cylinder 10.

[0058] It should be emphasized that the rotation of the abutting member 1212 to drive the cantilever 1213 to movably abut against the end of the locking rod away from the locking end can be achieved by the drive of the first motor 1211 or by external force.

[0059] In some examples, such as Figures 1 to 6 As shown, the driving assembly 122 includes a first driving member 1221, and a mounting platform 1222 is protruded along the axial direction of the first driving member 1221, and a sliding hole 1223 is provided through the mounting platform 1222 along the radial direction of the first driving member 1221;

[0060] The mounting platform 1222 is provided with a limiting groove 1224, which is also extended along the circumference of the first driving member 1221. The cantilever 1213 extends into the limiting groove 1224, and the cantilever 1213 can be movably abutted against the groove walls on both sides of the circumference of the limiting groove 1224 to limit the rotation angle of the first driving member 1221.

[0061] With such arrangement, the cantilever 1213 can abut against the wall of the limiting groove 1224 to limit the rotation angle of the first driving member 1221, thereby causing the first motor 1211 to stop rotating and limiting the first motor 1211 from driving the abutting member 1212 to rotate continuously.

[0062] In one embodiment, part of the circumferential side of the mounting boss can be fixedly connected to the mounting groove, so that the first drive member 1221 can rotate synchronously with the first lock cylinder shell 124. In another embodiment, the first drive member 1221 is clamped with the first lock cylinder shell 124 through the above-mentioned locking pin 1231, so that the first drive member 1221 can rotate synchronously with the first lock cylinder shell 124.

[0063] In some examples, such as Figures 2 to 4 As shown, the first lock core shell 124 is circumferentially provided with an elongated hole 1242 connected to the mounting groove, and the lock core 10 also includes a reset pin 14 and a reset magnet 15. The reset pin 14 is elastically mounted on the lock tube 13. The reset pin 14 extends out of the first mounting groove 1241 through the elongated hole 1242 and elastically abuts against the cantilever 1213 to flexibly limit the rotation of the abutting piece 1212. The reset magnet 15 is fixedly mounted on the lock tube 13, and the magnetic force acts on the abutting piece 1212 to make the cantilever 1213 abut against the end of the locking rod away from the locking end.

[0064] In this way, under the action of external force, the locking module 12 drives the driving assembly 122 to rotate to act on the lock body, so that the lock body is unlocked. Under the action of external force, the locking module 12 drives the driving assembly 122 to rotate in the opposite direction to act on the lock body, so that during the locking operation of the lock body, the reset pin 14 extends into the installation groove through the elongated hole 1242 and elastically abuts against the cantilever 1213 to flexibly limit the rotation of the abutting piece 1212. 2, the other parts of the locking module 12 can continue to rotate in the opposite direction, while the push piece 1212 cannot rotate. At the same time, the magnetic force of the reset magnet 15 acts on the push piece 1212, so that the cantilever 1213 is again connected to the end of the locking rod away from the locking end. In this way, through the action of the reset pin 14 and the reset magnet 15, there is no need for the first motor 1211 to drive the push piece 1212 to flip, so that the locking end and the locking pit 132 can cooperate to lock the locking module 12 and the locking tube 13.

[0065] In some examples, such as Figures 1 to 3 As shown, the lock tube 13 is also provided with an avoidance opening 133 connected to the first receiving groove 131, and the driving assembly 122 also includes a dial 1225. The first driving member 1221 is rotatably mounted on the first receiving groove 131, and the dial 1225 is fixedly mounted on the peripheral side of the first driving member 1221 and extends out of the first receiving groove 131 through the avoidance opening 133, acting on the lock body, so that the lock body performs an unlocking operation.

[0066] With such arrangement, under the action of external force, the locking module 12 drives the first driving member 1221 to rotate, and the first driving member 1221 drives the dial 1225 fixedly mounted on the peripheral side to move, and the dial 1225 extends out of the receiving groove through the avoidance opening 133 and acts on the lock body, thereby realizing the unlocking operation of the lock body.

[0067] In some examples, such as Figure 1As shown, the locking module 12 also includes a knob 128, which is fixedly mounted on an end of the first lock core housing 124 away from the motor and is formed with a hollow portion 1281 for avoiding the data connector 111, so that the first lock core housing 124 can be driven to rotate through the knob 128 under the action of external force.

[0068] With such arrangement, after the cantilever 1213 is movably separated from the locking structure 123, the knob 128 can be used to apply external force to the locking module 12, and the user's operation on the knob 128 is transmitted to the lock body through the locking module 12, which is convenient for the user's operation.

[0069] In some examples, such as Figures 6 to 8 As shown, the lock core 10 also includes a lock core shell 16 and a positioning pin 17. The lock core shell 16 is provided with a second receiving groove 161 and a through hole connected to the second receiving groove 161. The locking module 12 is installed in the second receiving groove 161. The positioning pin 17 extends into the second receiving groove 161 through the hole and is fixedly connected to the locking module 12.

[0070] There are many ways to fasten the positioning pin 17 to the locking module 12. The positioning pin 17 can be threadedly connected to the locking module 12, interference fit, etc. With this arrangement, the connection between the locking module 12 and the lock core shell 16 is more firm and stable. Compared with the above-mentioned solution in which the locking module 12 is rotatably installed in the first receiving groove 131 of the lock tube 13 shell, the applicable scenarios of the lock core 10 can be increased.

[0071] In some examples, such as Figure 7 and Figure 8 As shown, the locking module 12 also includes a second lock core shell 126, the second lock core shell 126 is provided with a second mounting groove 1261, the locking module 12 includes a second driving device 125, the second driving device 125 includes a second motor 1251 and a second driving member 1252, the second motor 1251 is fixedly installed in the second mounting groove 1261, the second driving member 1252 is rotatably installed in the second mounting groove 1261, the second motor 1251 is transmission-connected with the second driving member 1252, so that when the controller 112 controls the locking module 12 to work according to the identity information, the second driving member 1252 is driven to rotate by the second motor 1251 to act on the lock body, so that the lock body is unlocked.

[0072] With such a configuration, the lock core 10 can directly drive the second driving member 1252 to rotate on the lock body through the second motor 1251, thereby reducing the number of parts for transmitting power and thus reducing energy loss during the power transmission process.

[0073] In some examples, such as Figure 7 and Figure 8As shown, the lock core 10 also includes a reset assembly 18, which includes a torsion spring 181, an angle limiter of the torsion spring 181 and a rotation angle limiter (not shown). The angle limiter of the torsion spring 181 is fixedly mounted on the second motor 1251, and the torsion spring 181 is sleeved on the driving shaft of the second motor 1251. One end of the torsion spring 181 is elastically abutted against the angle limiter of the torsion spring 181, and the other end of the torsion spring 181 is elastically abutted against the second driving member 1252. The rotation angle limiter acts on the driving end 1253 of the second driving member 1252 to limit the rotation angle of the second driving member 1252.

[0074] Among them, the rotation angle limiter can be fixedly connected to the lock core, can also be connected to other components of the lock core 10, and can also be connected to other components of the smart lock.

[0075] With such arrangement, when the second motor 1251 stops driving the second driving member 1252, the torsion spring 181 can apply a resetting elastic force to the second driving member 1252, so that the second driving member 1252 is automatically reset, and the rotation angle of the second driving member 1252 can be controlled by the rotation angle limiter.

[0076] In some examples, such as Figure 7 and Figure 8 As shown, the locking module 12 also includes a stabilizing ball assembly 127, which is elastically mounted on the circumferential side of the second driving member 1252, and the groove wall of the second mounting groove 1261 is also recessed with a card hole that cooperates with the stabilizing ball assembly 127.

[0077] With such arrangement, when the second driving member 1252 stops rotating, it can be kept at the corresponding position under slight external force and will not move. Similarly, the above-mentioned abutting member 1212 can be arranged similarly.

[0078] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
