If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0039] This invention proposes a smart door lock 100, which can be applied to homes, offices, and other places. Please refer to the following references. Figures 1 to 3 In this embodiment of the invention, the smart door lock 100 includes a locking / unlocking device 30, a lock body 20, and an emergency unlocking structure.

[0040] The locking / unlocking device 30 includes a first lock cylinder and a panel assembly. When authentication is successful, the panel assembly controls the first lock cylinder to operate, enabling the lock body 20 to perform locking / unlocking operations under the operation of the first lock cylinder. The panel assembly typically includes two panels, respectively installed on the front and rear sides of the door. The panel assembly may include a password unlocking module, a fingerprint unlocking module, a Bluetooth unlocking module, etc. These unlocking modules are used to verify the identity information of the person performing the unlocking / unlocking operation. The panel assembly only controls the first lock cylinder to operate when the operator's authentication is successful; otherwise, it does not control the first lock cylinder to operate.

[0041] The emergency unlocking structure includes a second lock cylinder 10, which includes a control component 11 and a locking module 12. The control component 11 includes a data connector 111 adapted to the data interface of the mobile phone and a controller 112. The data connector 111 is used to collect the identity information of the mobile phone and obtain the power 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 20 performs locking and unlocking operations under the operation of the locking module 12.

[0042] The emergency unlocking structure may also include a purely mechanical unlocking module for unlocking with a mechanical key, and may also include a purely mechanical recording structure to record the number of times the emergency unlocking structure is used for unlocking.

[0043] The data connector 111 is primarily used to interface with a mobile phone's data interface. Therefore, the data connector 111 must be compatible with mainstream mobile phone data interfaces on the market, including but not limited to Type-C data connector 111 and Micro USB data connector 111. When not in use, the data interface can be hidden within the door or panel assembly, only being exposed when needed to minimize its exposure to the environment and prevent damage to the metal pins within the data interface.

[0044] When using this emergency unlocking structure to unlock the smart door lock 100, the data connector 111 works with the mobile phone's data interface to collect 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 work, so that the lock body 20 performs locking and unlocking operations under the operation of the locking module 12.

[0045] There are several ways in which the lock body 20 can perform locking and unlocking operations under the operation of the locking module 12. In one way, the locking module 12 uses the electrical energy obtained from the data connector 111 to directly drive the lock body 20 to perform locking and unlocking operations. In another way, the locking module 12 includes a handle and a smart lock cylinder. The handle is connected to the lock body 20, and the controller 112 controls the smart lock cylinder to lock or unlock the handle, restricting or releasing the handle's operation on the lock body 20, thus performing indirect locking and unlocking operations.

[0046] According to the above technical solution, the second lock cylinder 10 includes a control component 11 and a locking module 12. The control component 11 includes a data connector 111 adapted to the data interface of the mobile phone and a controller 112. The data connector 111 is used to collect the identity information of the mobile phone and obtain the power required for the operation of the locking module 12. The locking module 12 is electrically connected to the controller 112. The controller 112 also controls the operation of the locking module 12 according to the identity information, so that the lock body 20 performs locking and unlocking operations under the operation of the locking module 12. With this setup, when the smart lock 100 is in normal use, the user can use the panel assembly to lock and unlock the lock body 20. When the panel assembly loses power or malfunctions, the user can use the mobile phone's data interface to connect with the data connector 111 to verify the user's identity information with the smart lock 100 and provide the necessary power to the locking module 12. This allows the controller 112 to control the locking module 12, enabling the lock body 20 to lock and unlock under the operation of the locking module 12. Thus, when the panel assembly loses power or malfunctions, the user does not need to use a mechanical key and can quickly unlock the lock using their mobile phone, improving the convenience and reliability of the smart lock 100.

[0047] In some examples, such as Figures 3 to 5As shown, the second lock cylinder 10 also includes a lock tube 13, which has a receiving groove 131. The locking module 12 is rotatably mounted in the receiving groove 131. The locking module 12 includes a drive device 121, a drive assembly 122, and a locking structure 123. The locking structure 123 is movably mounted on the drive assembly 122. The 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. When the locking module 12 is unlocked from the lock tube 13, the locking module 12 can rotate relative to the lock tube 13 under the action of external force, so that the locking module 12 drives the drive assembly 122 to rotate, thereby acting on the lock body 20 and causing the lock body 20 to perform locking and unlocking operations.

[0048] There are several ways in which the driving device 121 acts on the locking structure 123. In one way, the 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 inserted into the limiting hole on the lock tube 13, restricting the relative movement of the locking module 12 and the lock tube 13, thus locking the locking module 12 and the lock tube 13. The unlocking principle is similar to the above and will not be described in detail. In another way, the locking structure 123 is elastic and elastically abuts against the lock tube 13. When the driving device 121 acts on the locking structure 123, the driving device 121 restricts the elastic movement of the locking structure 123, thereby locking the locking module 12 and the lock tube 13. When the driving device 121 does not act on the locking structure 123, since the locking structure 123 elastically abuts against the lock tube 13, the lock tube 13 can elastically squeeze the locking structure 123 when the locking module 12 moves relative to the lock tube 13.

[0049] With this configuration, the drive unit 121 acts on the locking structure 123 to lock or unlock the locking module 12 and the lock tube 13. This indirectly controls the operation of the locking module 12 on the lock body 20 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 electrical energy to drive the locking and unlocking operation of the lock body 20. When the locking module 12 and the lock tube 13 are unlocked, the user can apply external force to the locking module 12 to drive the drive component 122 to rotate, thereby acting on the lock body 20 and causing the lock body 20 to perform the locking and unlocking operation. The drive unit 121 can also operate normally even with low output power, so the drive unit 121 can be miniaturized, while reducing the load on the power supply of the mobile phone.

[0050] In some examples, such as Figures 3 to 5As shown, the driving device 121 includes a motor 1211 and a stop member 1212. The motor 1211 is connected to the stop member 1212 to drive the stop member 1212 to move into or out of the locking structure 123. When the stop member 1212 moves into 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 stop member 1212 moves out of 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.

[0051] There are several ways to drive the motor 1211 and the abutment 1212. In one way, the abutment 1212 has an inclined surface, and the motor 1211 drives the abutment 1212 to reciprocate in a straight line, so that the abutment 1212 can be movably abutted against or movably separated from the locking structure 123 through the inclined surface. In another way, the abutment 1212 has a cantilever 1213, and the motor 1211 drives the abutment 1212 to rotate, so that the abutment 1212 can be movably abutted against or movably separated from the locking structure 123 through the cantilever 1213.

[0052] With this configuration, the motor 1211 can directly drive the abutment 1212 to move, causing the abutment 1212 to move into contact with or separate from the locking structure 123, thereby restricting the movement of the locking structure 123 or releasing the restriction on the locking structure 123. In this way, the abutment 1212 is used to unlock or lock the locking module 12 and the lock tube 13 by the locking structure 123, indirectly controlling the operation of the locking module 12 on the lock body 20.

[0053] In some examples, such as Figures 3 to 5 As shown, the locking module 12 also includes a lock cylinder shell 124. The lock cylinder shell 124 is provided with a mounting groove 1241. The motor 1211 is fixedly mounted in the mounting groove 1241. The abutment 1212 is rotatably mounted in the mounting groove 1241. A cantilever 1213 protrudes from the side of the abutment 1212 away from the motor 1211. The cantilever 1213 also extends along the axis of rotation of the abutment 1212 in a direction away from the motor 1211 and is also spaced apart from the axis. The cantilever 1213 can be movably abutted or movably separated from the locking structure 123.

[0054] With this configuration, the rotation of the abutment 1212 is smoother during the rotation of the motor 1211 driving the abutment 1212, which improves the reliability of the motor 1211 and thus improves the stability of the locking module 12 operation.

[0055] In some embodiments, such as Figure 3As shown, the locking module 12 also includes a retaining bead assembly 127, which is elastically mounted on the periphery of the abutment member 1212. The groove wall of the mounting groove 1241 is also recessed with a locking hole that cooperates with the retaining bead assembly 127, so that when the abutment member 1212 stops rotating, it can be kept in the corresponding position under slight external force and will not shift.

[0056] In some examples, such as Figures 3 to 6 As shown, the drive assembly 122 is provided with a sliding hole 1223, and 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 the side of the locking end near the locking rod, and the other end of the spring 1232 elastically abuts against the wall of the sliding hole 1223 to elastically support the locking pin 1231. The groove wall of the receiving groove 131 is recessed with a locking pit 132 that cooperates with the locking end. The motor 1211 drives the abutment 1212 to rotate, so as to drive the cantilever 1213 to move and abut or move away from the end of the locking rod away from the locking end. The locking module 12 and the locking tube 13 are locked or unlocked by the cooperation of the locking end and the locking pit 132.

[0057] In this embodiment, the side of the locking end that mates with the locking slot 132 is spherical, and the edge of the locking slot 132 is arc-shaped, so as to facilitate the locking end entering or exiting the locking slot 132 and improve the smoothness of the rotation of the drive assembly 122.

[0058] With this configuration, after the cantilever 1213 and the locking rod are separated, the locking pin 1231, which is 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 that the abutment 1212 can rotate, causing the cantilever 1213 and the end of the locking rod away from the locking end to move and abut against each other, thereby improving the operating efficiency of the smart door lock 100.

[0059] It should be emphasized that the rotation of the abutment 1212 causing the cantilever 1213 to move and abut against the end of the locking rod away from the locking end can be achieved by the motor 1211 or by external force.

[0060] In some examples, such as Figures 2 to 7 As shown, the drive assembly 122 includes a drive member 1221. The drive member 1221 has a mounting platform 1222 protruding along the axial direction. The mounting platform 1222 has a sliding hole 1223 extending through it radially along the drive member 1221. The mounting platform 1222 has a limiting groove 1224. The limiting groove 1224 also extends circumferentially along the drive member 1221. A cantilever 1213 extends into the limiting groove 1224. The cantilever 1213 can move and abut against the groove walls on both sides of the limiting groove 1224 in the circumferential direction to limit the rotation angle of the drive member 1221.

[0061] With this configuration, the angle of rotation of the drive component 1221 can be limited by the contact between the cantilever 1213 and the wall of the limiting groove 1224, thereby causing the motor 1211 to stall and stop, and preventing the motor 1211 from driving the abutment component 1212 to rotate continuously.

[0062] In one embodiment, a portion of the periphery of the mounting boss can be fixedly connected to the mounting groove 1241, so that the driving member 1221 can rotate synchronously with the lock cylinder shell 124. In another embodiment, the driving member 1221 is engaged with the lock cylinder shell 124 through the aforementioned locking pin 1231, so that the driving member 1221 can rotate synchronously with the lock cylinder shell 124.

[0063] In some examples, such as Figures 3 to 5 As shown, the lock cylinder housing 124 is provided with an elongated hole 1242 communicating with the mounting groove 1241 in the circumferential direction. The second lock cylinder 10 also includes a reset spring pin 14 and a reset magnet 15. The reset spring pin 14 is elastically installed on the lock tube 13. The reset spring pin 14 extends out of the mounting groove 1241 through the elongated hole 1242 and elastically abuts against the cantilever 1213 to restrict the rotation of the abutment 1212. The reset magnet 15 is fixedly installed on the lock tube 13 and acts magnetically on the abutment 1212 so that the cantilever 1213 abuts against the end of the locking rod away from the locking end.

[0064] With this configuration, under external force, the locking module 12 drives the drive assembly 122 to rotate, which in turn acts on the lock body 20, causing the lock body 20 to unlock. Then, under external force, the locking module 12 drives the drive assembly 122 to rotate in the opposite direction, acting on the lock body 20. During the locking operation of the lock body 20, the reset pin 14 extends through the elongated hole 1242 into the mounting groove 1241 and elastically abuts against the cantilever 1213, thus restricting the rotation of the abutment 1212. Because the cantilever 121... The action of the abutment 1212 allows other components of the locking module 12 to continue rotating in the opposite direction, while the abutment 1212 cannot rotate. At the same time, the magnetic force of the reset magnet 15 acts on the abutment 1212, causing the cantilever 1213 to abut against the end of the locking rod away from the locking end again. Thus, through the action of the reset spring pin 14 and the reset magnet 15, the locking end and the locking pit can be engaged to lock the locking module 12 and the locking tube 13 without the motor 1211 driving the abutment 1212 to rotate.

[0065] In some examples, such as Figures 2 to 4 As shown, the lock tube 13 is also provided with a clearance opening 133 communicating with the receiving groove 131. The drive assembly 122 includes a drive member 1221 and a dial 1225.
