[0073] The present invention proposes an emergency unlocking mechanism 30, please refer to Figures 1 to 16 In an embodiment of the present invention, an emergency unlocking mechanism 30 is applied to a smart door lock. The smart door lock with the emergency unlocking mechanism 30 can be applied to homes, offices and other places. The emergency unlocking mechanism 30 includes a first lock core 31 and an authorization module 32.

[0074] The first lock core 31 includes a shell 311, a handle drive assembly 312, a clutch assembly and a shift block 314. The shell 311 is provided with a mounting groove 311a and a connecting hole 311b connected to the inner wall of the peripheral side of the mounting groove 311a. The handle drive assembly 312 is movably mounted in the mounting groove 311a and partially exposed outside the mounting groove 311a. The shift block 314 is rotatably mounted in the shell 311 and partially located in the mounting groove 311a. The clutch assembly is movably mounted in the mounting groove 311a and connected to the shift block 314. The shift block 314 is used to drive the lock body 20 of the smart door lock to unlock the lock body 20.

[0075] The authorization module 32 is installed on the shell 311. The authorization module 32 also obtains external power through the emergency power supply module 40 of the smart door lock. The authorization module 32 includes a movable authorization component 321 and a control component. After obtaining external power, the control component controls the authorization component 321 to enter the installation groove 311a through the connecting hole 311b, so that the handle drive component 312 is linked with the clutch component through the authorization component 321.

[0076] It should be noted that the authorization module 32 can obtain external power through the emergency power supply module 40 only after the emergency power supply module 40 of the smart door lock verifies the authority of the external device. After obtaining external power, the control component uses the external power to control the authorization member 321 to enter the installation slot 311a through the connection hole 311b, so that the handle drive component 312 can be linked with the clutch component through the authorization member 321, and the authority to operate the emergency unlocking mechanism 30 can be obtained. The user operates the handle drive component 312 to drive the clutch component linked with the handle drive component 312 to move, so as to use the clutch component to drive the shift block 314 to move, so as to perform the unlocking operation on the lock body 20. When the authorization component does not obtain external power, the handle drive component 312 and the clutch component are in a non-linked state, that is, the user does not have the operating authority to operate the emergency unlocking mechanism 30, and operating the handle drive component 312 will not drive the clutch component to move. In this way, the handle drive component 312 will only idle when subjected to external force, which can well protect the emergency unlocking mechanism 30 from being damaged by external force.

[0077] It should be emphasized that the authorization member 321 in the installation slot 311a does not mean that the handle drive assembly 312 is linked to the clutch assembly, that is, the authorization member 321 in the installation slot 311a does not mean that the user has the authority to operate the emergency unlocking mechanism 30. In some examples, the authorization member 321 is located in the installation slot 311a by elastic force, but under the action of a slight external force, it can retreat to the connection hole 311b and leave the installation slot 311a. It can be understood that the control component uses external electric energy to control the authorization member 321 to enter the installation slot 311a through the connection hole 311b, and the handle drive assembly 312 and / or the clutch assembly exert a force on the authorization member 321, which will not retreat to the connection hole 311b, so that the handle drive assembly 312 can stably be linked to the clutch member through the authorization member 321. When the control component does not obtain electric energy, the authorization member 321 may be located in the installation groove 311a due to external force, but the handle drive component 312 and / or the clutch component exert a force on the authorization member 321, which will retreat to the connecting hole 311b, and the handle drive component 312 cannot be linked with the clutch component through the authorization member 321.

[0078] The housing 311 is usually provided with an escape portion connected to the mounting groove 311a, and the shift block 314 is rotatably mounted on the escape portion. A portion of the shift block 314 is located in the mounting groove 311a, and the other portion of the shift block 314 is exposed from the housing 311 through the escape portion and connected to the lock body 20.

[0079] The present invention adopts the above-mentioned technical scheme, which includes a first lock core 31 and an authorization module 32. The authorization module 32 obtains external power through the emergency power supply module 40 of the smart door lock. After obtaining the external power, the control component of the authorization module 32 controls the authorization component 321 to enter the installation slot 311a through the connecting hole 311b located on the peripheral side of the installation slot 311a, so that the handle drive component 312 is linked with the clutch component through the authorization component 321. After the handle drive component 312 is linked with the clutch component, the user can operate the handle drive component 312 to drive the clutch component linked with the handle drive component 312 to move, thereby using the clutch component to drive the shift block 314 to move, so as to unlock the lock body 20. It can be seen that compared with the prior art, the technical solution of the present application does not need to use a passive electronic lock core to obtain external power from an external device and to perform identity authentication to obtain permission to operate the emergency unlocking mechanism 30, and does not need to manually drive the rotating part to rotate with the passive electronic lock core. The emergency unlocking mechanism 30 provided in the present application obtains external power through the emergency power supply module 40, and the control component controls the authorization component 321 to enter the installation slot 311a through the connecting hole 311b located on the side of the installation slot 311a, so that the handle drive component 312 is linked with the clutch component through the authorization component 321. The user can use the emergency unlocking mechanism 30 to achieve emergency unlocking by operating the handle drive component 312 to drive the shift block 314 to move, thereby improving the efficiency of emergency unlocking.

[0080] In some examples, such as Figures 3 to 16 As shown, the shell 311 is also provided with a receiving groove 311c connected to the connecting hole 311b, and the authorization module 32 is installed in the receiving groove 311c. The control component includes an elastic component 322, a driving member and a locking member. The elastic component 322 is elastically installed in the receiving groove 311c and elastically presses the authorization member 321 in the installation groove 311a. The driving member is transmission-connected with the locking member to drive the locking member to lock with the elastic component 322 to limit the authorization member 321 from retreating to the connecting hole 311b.

[0081] With such a configuration, the authorization member 321 is elastically pressed against the elastic component 322 and is located in the installation slot 311a. When the user obtains the authority to operate the first lock core 31, the driving member drives the locking member to lock and cooperate with the elastic component 322 to lock the elastic component 322 and prevent relative movement, thereby limiting the authorization member 321 from retreating to the connection hole 311b. When the user does not obtain the authority to operate the second lock core, the authorization member 321 can retreat to the connection hole 311b under the action of the handle driving component 312 and the clutch component, so that the handle driving component 312 can only idle under the action of external force and cannot form a linkage relationship with the clutch component. The authorization member 321 is elastically pressed against the installation slot 311a by the elastic component 322. After the control component obtains external electrical energy, the driving member can quickly drive the locking member to lock and cooperate with the elastic component 322 to quickly provide the user with the authority to operate the second lock core.

[0082] In some examples, such as Figure 3 , Figure 4 as well as Figures 8 to 11 As shown, the authorization module 32 also includes a first base 326, the first base 326 is provided with a first sliding hole 326a and a first avoidance hole connected to the first sliding hole 326a, the elastic component 322 includes a first push pin 3221 and a first spring 3222, the first push pin 3221 can be movably installed in the first sliding hole 326a, the first push pin 3221 is also provided with a limiting groove 322a, and the first spring 3222 is elastically supported between the first push pin 3221 and the hole wall of the first sliding hole 326a.

[0083] The driving member includes a solenoid driver 3231 , which is fixedly mounted on the first base 326 . The locking member is an iron core 324 . The solenoid driver 3231 drives the iron core 324 to be plugged into and matched with the limiting groove 322 a through the first avoidance hole to limit the movement of the first ejector pin 3221 .

[0084] In this way, the solenoid driver 3231 drives the iron core 324 to engage with the limiting groove 322a through the first avoidance hole, which can stably limit the axial movement of the first push pin 3221, so as to better limit the authorization member 321 from retreating to the connecting hole 311b. In addition, the first spring 3222 is elastically supported between the first push pin 3221 and the hole wall of the first sliding hole 326a. When the user does not have the authority to operate the first lock core 31, the authorization member 321 can elastically squeeze the first push pin 3221 under the action of external force, so that the authorization member 321 can elastically retreat to the connecting hole 311b.

[0085] In some examples, such as Figures 12 to 16As shown, the authorization module 32 also includes a second base 327, the second base 327 is provided with a second sliding hole 327a, the elastic component 322 includes a second top pin 3223 and a second spring 3224, the second top pin 3223 can be movably installed in the second sliding hole 327a groove, and the second spring 3224 is elastically supported between the second top pin 3223 and the hole wall of the second sliding hole 327a.

[0086] The driving member includes a motor 3232, which is fixedly mounted on the second base 327. The locking member is a contact block 325, which is located at one end of the second ejector pin 3223 away from the authorization member 321 and has an avoidance surface for avoiding the second ejector pin 3223 and an abutment surface for abutting the second ejector pin 3223. The motor 3232 drives the abutment block 325 to rotate so that the abutment surface abuts the second ejector pin 3223 to limit the movement of the second ejector pin 3223.

[0087] In this configuration, the abutment block 325 is driven to rotate by the motor 3232, so that the abutment surface abuts against the second ejector pin 3223, and the axial movement of the second ejector pin 3223 can be stably limited, so as to better limit the authorization member 321 from retreating to the connection hole 311b. In addition, the second spring 3224 is elastically supported between the second ejector pin 3223 and the hole wall of the second sliding hole 327a, and when the user does not obtain the authority to operate the second lock core, the authorization member 321 can elastically squeeze the second ejector pin 3223 under the action of external force, so that the authorization member 321 can elastically retreat to the connection hole 311b.

[0088] In some examples, such as Figures 3 to 16 As shown, the handle driving assembly 312 is provided with a driving groove 312a, and the clutch assembly includes a rotating member 3131. The rotating member 3131 is rotatably installed in the installation groove 311a, and a rotating groove 3131a is arranged along its axial direction.

The rotating member 3131 is also provided with a clamping hole 3131c connected with the rotating groove 3131a, so that the authorization member 321 can abut against the driving groove 312a through the clamping hole 3131c, so that the handle driving assembly 312 is linked with the rotating member 3131 through the authorization member 321.

[0089] In this configuration, one end of the authorization member 321 abuts against the driving slot 312a via the clamping hole 3131c, and the other end of the authorization member 321 is constrained by the clamping hole 3131c of the installation slot 311a, and the authorization member 321 cannot be retracted into the connecting hole 311b under the control of the control component, so that the handle driving component 312 is linked with the rotating member 3131 through the authorization member 321, and the user can drive the rotating member 3131 to rotate by rotating the handle driving component 312. In addition, when the authorization member 321 is not in the installation slot 311a or the authorization member 321 can be retracted into the connecting hole 311b by external force, the handle driving component 312 can easily idle relative to the rotating member 3131.

[0090] In some examples, such as Figure 3 and Fig.12 As shown, the handle driving assembly 312 includes a driving shaft 3121 and a handle 316. The handle 316 is fixedly connected to the driving shaft 3121, so that the user can synchronously drive the driving shaft 3121 to move by operating the handle 316, thereby improving the comfort of operating the smart door lock. The driving shaft 3121 is movably mounted in the mounting groove 311a, the handle 316 is exposed in the mounting groove 311a, and the driving groove 312a is formed in the driving shaft 3121.

[0091] In some examples, an annular locking groove 3131d is also recessed on the circumferential side of the rotating member 3131, and the shell 311 is provided with a stabilizing ball assembly, and the stabilizing beads of the stabilizing ball assembly are engaged with the locking groove 3131d to limit the axial movement of the rotating member 3131, wherein the stabilizing ball assembly elastically supports the stabilizing beads through springs.

[0092] In some examples, such as Figures 3 to 11 As shown, the driving groove 312a is extended along its axial direction, and the clutch assembly also includes a first clutch shaft 3132. The circumferential side of the first clutch shaft 3132 is provided with a first driving portion 3132a extending along its axial direction. The groove wall of the rotating groove 3131a is also provided with a first matching groove 3131b for transmission cooperation with the first driving portion 3132a. The shift block 314 is provided with a connecting groove 314a connected to the rotating groove 3131a. The groove wall of the connecting groove 314a is also provided with a second matching groove 314b for transmission cooperation with the first driving portion 3132a. The first clutch shaft 3132 is also elastically supported on one end of the handle driving assembly 312 by a first sleeve spring 3133, so that when the first matching groove 3131b is aligned with the second matching groove 314b, the handle driving assembly 312 can be driven to extend into the connecting groove 314a, elastically squeeze the first clutch shaft 3132 into the connecting groove 314a, so that part of the first driving portion 3132a is transmission-coordinated with the second matching groove 314b.

[0093] With such arrangement, the driving handle driving assembly 312 extends into the connecting groove 314a to elastically squeeze the first clutch shaft 3132, and the handle driving assembly 312 drives the rotating member 3131 to rotate a certain angle, so that when the first matching groove 3131b on the rotating member 3131 is aligned with the second matching groove 314b, the first clutch shaft 3132 enters the connecting groove 314a under the elastic force of the first set spring 3133, and then the part of the first driving part 3132a is matched with the second matching groove 314b to realize the linkage between the rotating member 3131 and the shift block 314.

[0094] In some examples, such as Figures 3 to 11 As shown, the clutch assembly further includes a second clutch shaft 3134 , and a second driving portion 3134 a is provided on the circumferential side of the second clutch shaft 3134 along its axial extension and can be transmission-matched with the second matching groove 314 b .

[0095] The first lock core 31 also includes a rear shaft 315, which is rotatably installed in the installation groove 311a and is located on the side of the shift block 314 away from the rotating member 3131. The rear shaft 315 is provided with a rear shaft groove 315a connected to the connecting groove 314a, and the groove wall of the rear shaft groove 315a is provided with a third matching groove 315b for transmission matching with the second driving part 3134a.

[0096] The second clutch shaft 3134 is also elastically supported on the rear axle groove 315a by the second set of springs 31373135, so that after the first driving portion 3132a of the first clutch shaft 3132 withdraws from the second matching groove 314b and the third matching groove 315b is aligned with the second matching groove 314b, the elastic force of the second set of springs 31373135 enters the connecting groove 314a, so that part of the second driving portion 3134a is matched with the second matching groove 314b for transmission.

[0097] In this way, the rear shaft 315 can be used by a person at the rear side of the door body to unlock the smart door lock, that is, the person at the rear side of the door body can operate the emergency unlocking mechanism 30 through the rear shaft 315 to unlock the lock body 20. It should be emphasized that when the person at the rear side of the door body operates the emergency unlocking mechanism 30, there is no need for the authorization module 32 to obtain power through the emergency power supply module 40.

[0098] In some examples, such as Figures 3 to 8 As shown, the groove wall of the mounting groove 311a is further provided with two annular grooves 311d, and the two annular grooves 311d are further arranged at intervals along the axial direction of the handle driving assembly 312, and a passage 311e is further provided between the two annular grooves 311d. A limiting protrusion 312b is provided on the circumferential side of the handle driving assembly 312, and the limiting protrusion 312b is slidably matched with the annular groove 311d and can enter the other annular groove 311d through the passage 311e.

[0099] In some examples, a spring is further provided between the handle driving assembly 312 and the rotating member 3131 , so as to provide elastic potential energy for the handle driving assembly 312 , so as to facilitate the handle driving assembly 312 to move in a direction away from the housing 311 along its axial direction.

[0100] This arrangement is intended to prevent the handle driving assembly 312 from being separated from the housing 311 when the handle driving assembly 312 moves along its axial direction. In addition, the annular groove 311d can make the handle driving assembly 312 rotate more smoothly and stably.

[0101] In some examples, such as Figures 12 to 16 As shown, the driving groove 312a is extended along its axial direction, the clutch assembly also includes a clutch shaft 3136, and a driving portion 3136a is extended along its axial direction on the circumferential side of the clutch shaft 3136, and the groove wall of the rotating groove 3131a is also provided with a first matching groove 3131b that can be matched with the driving portion 3136a in transmission, the shift block 314 is provided with a connecting groove 314a connected to the rotating groove 3131a, and the groove wall of the connecting groove 314a is also provided with a second matching groove 314b that is matched with the driving portion 3136a in transmission, and the first lock core 31 also includes a rear rotating shaft 315, the rear rotating shaft 315 is rotatably installed in the installation groove 311a, and is located on the side of the shift block 314 away from the rotating member 3131, the rear rotating shaft 315 is provided with a rear shaft groove 315a connected to the connecting groove 314a, and the groove wall of the rear shaft groove 315a is provided with a The clutch shaft 3136 is elastically supported on the circumferential side of the handle driving assembly 312 by two sets of springs 3137 in the third mating groove 315b which is mated with the driving portion 3136a for transmission. This allows the clutch shaft 3136 to be elastically squeezed into the rotating groove 3131a by driving the handle driving assembly 312 when the first mating groove 3131b is aligned with the second mating groove 314b, so that the driving portion 3136a is respectively mated with the first mating groove 3131b and the second mating groove 314b for transmission. Alternatively, when the third mating groove 315b is aligned with the second mating groove 314b, the clutch shaft 3136 can be elastically squeezed into the rear shaft groove 315a by driving the handle driving assembly 312 to be elastically squeezed into the rear shaft groove 315a, so that the driving portion 3136a is respectively mated with the third mating groove 315b and the second mating groove 314b for transmission.

[0102] With such arrangement, the driving handle driving assembly 312 moves along its axial direction toward the direction of exiting the mounting groove 311a to elastically squeeze the clutch shaft 3136, and drives the rotating member 3131 to rotate a certain angle through the handle 316 assembly, so that when the first matching groove 3131b is aligned with the second matching groove 314b, the clutch shaft 3136 enters the rotating groove 3131a under the elastic force of the sleeve spring 3137, and then the driving part 3136a is respectively matched with the first matching groove 3131b and the second matching groove 314b to realize the linkage between the rotating member 3131 and the shift block 314.

[0103] Compared with the above-mentioned solution in which the clutch assembly includes the first clutch shaft 3132 and the second clutch shaft 3134 , the solution of this embodiment is simpler and facilitates the assembly of the emergency unlocking mechanism 30 .

[0104] In some examples, such as Fig.12 As shown, the drive shaft 3121 also includes a shaft body and a sub-shaft. The shaft body is provided with a through hole along its axial direction. One end of the sub-shaft is rotatably mounted on the through hole. The clutch shaft 3136 is elastically supported on the circumference of the other end of the sub-shaft by two sets of springs 3137. The drive groove 312a is provided on the shaft body. Such a setting is intended to further reduce the difficulty of assembling the emergency unlocking mechanism 30.

[0105] This application also provides a smart door lock, please refer to Figures 1 to 16 In an embodiment of the present invention, the smart door lock includes a main control unlocking mechanism 10, a lock body 20 and the above-mentioned emergency unlocking mechanism 30.

[0106] The main control unlocking mechanism 10 includes a second lock core and a panel assembly 11. The panel assembly 11 can control the operation of the second lock core when the identity authentication is passed, so that the lock body 20 can be unlocked under the operation of the second lock core. The emergency power supply module 40 is used to obtain external power in an emergency, and can provide emergency power supply to the main control unlocking mechanism 10 or the emergency unlocking mechanism 30 through external power according to user demand information.

[0107] The panel assembly 11 usually includes two panels, which are respectively installed on the front and rear sides of the door body, wherein the panel assembly 11 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 operator who performs the unlocking. When the panel assembly 11 passes the identity authentication of the operator, the second lock core is controlled to work. When the panel assembly 11 fails the identity authentication of the operator, the second lock core is not controlled to work.

[0108] In some examples, the second lock core includes a driving structure that is transmission-connected to a lock tongue 21 of a lock body 20. When the panel assembly 11 controls the second lock core to operate, the driving structure drives the lock tongue 21 to retract into the lock body 20 to achieve an unlocking operation.

[0109] There are multiple ways for the emergency power supply module 40 to obtain external power in an emergency. In one way, the emergency power supply module 40 includes a power supply interface 42, and obtains external power by docking with an external device. In another way, the emergency power supply module 40 includes a power receiving coil, and the external device is provided with a power transmitting coil. The emergency power supply module 40 obtains power by electromagnetic coupling between the power receiving coil and the power transmitting coil.

[0110] The emergency power supply module 40 can obtain user demand information in a wired or wireless manner.

[0111] The smart door lock provided by the present application includes a main control unlocking mechanism 10, a lock body 20, an emergency unlocking mechanism 30 and an emergency power supply module 40. Under normal circumstances, the user can verify the identity information through the panel assembly 11 of the main control unlocking mechanism 10. When the identity authentication is passed, the panel assembly 11 controls the second lock core to work, so that the lock body 20 performs the unlocking operation under the operation of the second lock core; when the panel assembly 11 is out of power, the user can use the emergency power supply module 40 to obtain external power in an emergency, and can supply external power to the emergency power supply module 40 according to their own needs. The main control unlocking mechanism 10 or the emergency unlocking mechanism 30, if the main control unlocking mechanism 10 is powered on in an emergency, the user can perform the unlocking operation through the normal unlocking method. If the emergency unlocking mechanism 30 is powered on in an emergency, the user can perform identity authentication through the emergency power supply module 40. After the identity authentication is passed, the authorization module 32 obtains external power through the emergency power supply module 40, and then uses the emergency unlocking mechanism 30 to achieve emergency unlocking, providing users with two different unlocking methods to meet more scenario usage needs of different users, thereby improving the user experience.

[0112] In addition, in the smart door lock provided by the present application, the emergency power supply module 40 is first used to obtain external electric energy in an emergency, and then according to user needs, the main control unlocking mechanism 10 or the emergency unlocking mechanism 30 is powered by external electric energy for emergency. This power supply method can play a certain buffering role in the power supply current of the emergency power supply module 40, thereby avoiding unstable current from damaging the main control unlocking mechanism 10 and / or the emergency unlocking mechanism 30.

[0113] In some examples, such as Figure 1 and Figure 2 As shown, the emergency power supply module 40 includes a judge 41 and a power supply interface 42. The power supply interface 42 is used to connect with an external device to obtain external power through the external device. The judge 41 is used to obtain user demand information and is electrically connected to the power supply interface 42 to supply the external power obtained by the power supply interface 42 to the main control unlocking mechanism 10 or the emergency unlocking mechanism 30 in an emergency.

[0114] The power supply interface 42 is usually connected to a smart device, so the power supply interface 42 includes but is not limited to Type-C and Micro-USB. The preferred power supply interface is a Type-C solution, which increases the scope of application of the smart door lock. In some examples, the determiner 41 can obtain data information of an external device with the help of the power supply interface 42, so that the user can send demand information to the determiner 41 through the external device; in some examples, the determiner 41 includes a wireless transmission module to obtain user demand information through wireless transmission.

[0115] With such a configuration, a stable electrical connection can be established with an external device through the power supply interface 42 to stably obtain external electrical energy, thereby improving the reliability of the emergency power supply module 40 and further improving the user experience.

[0116] In one embodiment, if the determiner 41 does not obtain the user demand information within a preset time, the determiner 41 defaults to supplying the external power obtained by the power supply interface 42 to the main control unlocking mechanism 10 in an emergency manner.

[0117] Considering that people usually carry their mobile phones nowadays, in some examples, such as Figure 1 and Figure 2 As shown, the power supply interface 42 is a data male connector that is compatible with the data female connector of the mobile phone, and the data male connector is used to obtain external power from the mobile phone.

[0118] This setting is intended to further improve the convenience of using smart door locks. When the smart door lock is out of power, the user can use the mobile phone they carry with them to connect to the data male connector to provide power for the smart door lock.

[0119] In some examples, such as Figure 1 and Figure 2 As shown, the determiner 41 also obtains the user control instruction generated by the mobile phone through the data male connector, so as to supply the external electric energy obtained by the data male connector to the main control unlocking mechanism 10 or the emergency unlocking mechanism 30 in an emergency manner according to the user control instruction.

[0120] With such a configuration, the user can connect to the data male connector via a mobile phone and send user control instructions to the judger 41 via the data male connector. Specifically, the user control instructions can be sent to the judger 41 via a WeChat applet, an APP, a quick pop-up window, etc.

[0121] In some examples, such as Figure 1 and Figure 2 As shown, the determiner 41 is also used to perform authority verification on the external device that sends the user demand information, and after the authority verification is passed, the external power obtained by the power supply interface 42 is supplied to the authorization module 32 in an emergency manner.

[0122] Such a setting is intended to improve the integration of the smart door lock. In some examples, the power supply interface 42 is a data male connector, and the judge 41 obtains the user control instruction generated by the mobile phone through the data male connector, that is, the user demand information, and the judge 41 performs authority verification on the mobile phone according to the user control instruction.

[0123] In some examples, such as Figure 1 and Figure 2 As shown, the panel assembly 11 is also connected to the emergency power supply module 40 for communication, so as to obtain the user's identity information through the power supply interface 42, so that the panel assembly 11 can authenticate the user.

[0124] In combination with the above content, the power supply interface 42 can be a data male connector.

[0125] Such a setting is intended to enable the user to connect the power supply interface 42 through an external device, realize data transmission between the external device and the panel assembly 11, increase the identity authentication method of the panel assembly 11, and increase the unlocking methods that the user can choose.

[0126] Based on the above smart door lock, please refer to Fig.17 The present invention also provides an unlocking method, the unlocking method comprising the steps of:

[0127] Step S1: Provide a smart door lock and an external device with external power, and electrically connect the external device to the emergency power supply module to obtain external power.

[0128] Step S2: When a user control instruction is received, external power is controlled to be supplied to the emergency unlocking mechanism or the main unlocking mechanism according to the user instruction, so that the lock body performs an unlocking operation under the operation of the first lock core or the second lock core.

[0129] Step S3: When no user control instruction is received, external electric energy is directly controlled to be supplied to the main control unlocking mechanism in an emergency, so that the lock body performs an unlocking operation under the operation of the second lock core.

[0130] It is understandable that the smart door lock mentioned in the steps of this method may specifically be the smart door lock in the above embodiment, and the external device mentioned in the steps of this method includes but is not limited to a mobile phone, a power bank, a laptop computer, an electronic key, and the number of the external devices may be multiple. There are two main ways to electrically connect the emergency power supply module mentioned in the steps of this method to the external device, one is through the docking of wires, and the other is through the electromagnetic coupling of coils.

[0131] The user control instruction mentioned in the steps of the method is generated by an external device. Specifically, the user control instruction is usually generated by a user operating the external device, so that the external device generates the user control instruction according to the user's own needs.

[0132] In this way, when the panel assembly is out of power, the user can choose to provide emergency power to the main unlocking mechanism or the emergency unlocking mechanism according to their own needs to implement the emergency unlocking operation. Such a dual-channel unlocking method makes the emergency unlocking method not single, improves the unlocking efficiency in emergency situations, and improves the user experience.

[0133] In one application scenario, the operator (for example, the user) only has an identity authentication method for the panel component. The operator can choose to supply external power to the main control unlocking mechanism in an emergency according to his own situation and needs, so that the lock body can be unlocked under the operation of the first lock cylinder.

[0134] In another application scenario, the operator (for example, maintenance personnel) does not have an identity authentication method for the panel component. The operator can choose to supply external electrical energy to the emergency unlocking mechanism according to his own needs based on his own situation, so that the lock body can be unlocked under the operation of the first lock cylinder.

[0135] In another application scenario, the operator (for example, the user) has identity authentication methods for both the panel component and the authorization component. The operator can choose to supply external power to the main unlocking mechanism or the emergency unlocking mechanism in an emergency according to his own situation and needs, so that the lock body can be unlocked under the operation of the first lock core, or the lock body can be unlocked under the operation of the second lock core.

[0136] Please refer to Fig.18 Another embodiment of the unlocking method of the smart lock in the embodiment of the present invention controls the emergency supply of external electric energy to the emergency unlocking mechanism or the main control unlocking mechanism according to the user instruction, so that the lock body performs the unlocking operation under the operation of the first lock core or the second lock core, including:

[0137] Step S21: When the user control instruction is a regular unlocking command, the external electric energy is controlled to be supplied to the main control unlocking mechanism in an emergency manner, so that the panel assembly can authenticate the user.

[0138] Step S22: If the panel assembly passes the identity authentication, the second lock core is controlled to operate, so that the lock body performs an unlocking operation under the operation of the second lock core.

[0139] Step S23: If the panel assembly fails to pass the identity authentication, the second lock core will not be controlled to operate, so that the lock body cannot be unlocked.

[0140] In an embodiment of the present invention, the emergency power supply module controls the emergency supply of external electric energy to the main control unlocking mechanism according to the conventional unlocking command. After obtaining sufficient electric energy, the main control unlocking mechanism can achieve normal operation. The panel assembly of the main control unlocking mechanism has multiple unlocking modules that can be used to verify the identity information of the person performing the unlocking operation, and provide the user with a conventional unlocking method.

[0141] Please refer to Fig.19 , according to the user's instruction, the external electric energy is controlled to be supplied to the emergency unlocking mechanism or the main unlocking mechanism in an emergency, so that the lock body performs the unlocking operation under the operation of the first lock cylinder or the second lock cylinder, including:

[0142] Step S24: When the user control instruction is an emergency unlocking command, further performing an authority verification on the device that issues the user control instruction.

[0143] Step S25: If the authority verification is passed, the external power is controlled to be supplied to the emergency unlocking mechanism, so that after the authorization module obtains the external power, it controls the authorization component to link the handle drive assembly and the clutch assembly, thereby allowing the lock body to perform an unlocking operation under the operation of the first lock core.

[0144] Step S26: If the authority verification fails, external power is controlled not to be supplied to the emergency unlocking mechanism, so that the lock body cannot be unlocked.

[0145] In the embodiment of the present invention, the emergency power supply module controls the emergency supply of external electric energy to the emergency unlocking mechanism according to the emergency unlocking command. After obtaining the external electric energy, the control component of the authorization module controls the authorization component to enter the installation slot through the connecting hole located on the side of the installation slot, so that the handle drive component is linked with the clutch component through the authorization component. The power source of the unlocking operation mainly depends on the user's operation of the handle drive component. Therefore, the unlocking operation of the smart door lock realized by the emergency unlocking mechanism has low power demand and can achieve fast emergency unlocking.

[0146] 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.
