Description

Technical Field

[0001] This application relates to the field of lock technology, and in particular to an emergency locking / unlocking mechanism, a smart door lock, and an unlocking method. Background Technology

[0002] With the development of society and economy and the progress of technology, the gradual development of door lock devices has made door locks increasingly complex, especially smart door locks, which not only have complex mechanical structures, but also intelligent electronic components.

[0003] Smart door locks typically include a lock body embedded in the door and a main control unlocking / locking mechanism and an emergency unlocking / locking mechanism installed on the door. The main control unlocking / locking mechanism is used for the regular unlocking and locking of the smart door lock, while the emergency unlocking / locking mechanism is used for emergency unlocking and locking. The emergency unlocking / locking mechanism includes a passive electronic lock cylinder, a rotating component, and a lever. The passive electronic lock cylinder obtains external power from external devices while collecting the user's identity information for authentication. After authentication, it grants the user the authority to operate the emergency unlocking / locking mechanism, which drives the rotating component to move the lever to perform unlocking / locking operations on the lock body.

[0004] However, passive electronic lock cylinders are usually fixed in the rotating parts, and the power supply interface of the passive electronic lock cylinder needs to be exposed on one side of the rotating parts. As a result, when using the emergency unlocking and locking mechanism, users need to avoid external equipment and then drive the rotating parts and the passive electronic lock cylinder to rotate together, so as to drive the lever to rotate and realize the lock body's unlocking and locking operation. This makes it inconvenient for users to use the emergency unlocking and locking mechanism to realize emergency unlocking and locking, resulting in low emergency unlocking efficiency.

[0035] Provides a smart door lock as described above and an external device with external power, wherein the emergency power supply module is electrically connected to the external device to obtain the external power;

[0036] When a user control command is received, the external power supply is controlled to be supplied to the emergency unlocking / locking mechanism or the main unlocking / locking mechanism according to the user command, so that the lock body can perform unlocking / locking operations under the operation of the first lock cylinder or the second lock cylinder.

[0037] If the user control command is not received, the external power supply is directly controlled to supply emergency power to the main control unlocking and locking mechanism so that the lock body can perform unlocking and locking operations under the operation of the second lock cylinder.

[0038] In some embodiments of this application, the step of controlling the external power supply to the emergency unlocking / locking mechanism or the main unlocking / locking mechanism according to the user instruction, so that the lock body performs unlocking / locking operations under the operation of the first lock cylinder or the second lock cylinder, includes:

[0040] If the panel assembly passes the authentication, the second lock cylinder is controlled to operate, so that the lock body performs locking and unlocking operations under the operation of the second lock cylinder;

[0041] If the panel assembly fails the authentication, it will not control the second lock cylinder to work, thus preventing the lock body from performing unlocking and locking operations.

[0042] In some embodiments of this application, the step of controlling the external power supply to the emergency unlocking / locking mechanism or the main unlocking / locking mechanism according to the user instruction, so that the lock body performs unlocking / locking operations under the operation of the first lock cylinder or the second lock cylinder, includes:

[0043] When the user control command is an emergency unlock command, the device that issued the user control command will be further authorized.

[0044] If the authorization verification is successful, the external power supply is controlled to the emergency unlocking and locking 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 enabling the lock body to perform unlocking and locking operations under the operation of the first lock cylinder;

[0045] If the authorization verification fails, the external power supply to the emergency unlocking / locking mechanism will be cut off, preventing the lock from performing unlocking / locking operations.

[0046] The present invention, through the above-mentioned technical solution, includes a first lock cylinder and an authorization module. The authorization module obtains external power through the emergency power supply module of the smart door lock. After obtaining external power, the control component of the authorization module controls the authorization piece to enter the mounting slot through the connection hole located on the periphery of the mounting slot, so that the handle drive component is linked with the clutch component through the authorization piece. After the handle drive component and the clutch component are linked, the user can operate the handle drive component to drive the clutch component linked with the handle drive component to move, thereby using the clutch component to drive the toggle block to perform the locking and unlocking operation of the lock body. As can be seen, compared with the prior art, the technical solution of this application does not require the use of a passive electronic lock cylinder to obtain external power from external devices and to perform identity verification to obtain the authorization to operate the emergency unlocking and locking mechanism. Furthermore, it does not require manual driving of the rotating part to rotate together with the passive electronic lock cylinder. The emergency unlocking and locking mechanism provided by this application obtains external power through an emergency power supply module. The control component controls the authorization part to enter the mounting groove through the connection hole located on the periphery of the mounting groove, so that the handle drive component is linked with the clutch component through the authorization part. By operating the handle drive component, the user drives the toggle block to move, thereby realizing emergency unlocking and locking using the emergency unlocking and locking mechanism, which improves the efficiency of emergency unlocking.

[0073] This invention proposes an emergency unlocking and locking mechanism 30, please refer to the following reference. Figures 1 to 16 In this embodiment of the invention, the 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 cylinder 31 and an authorization module 32.

[0074] The first lock cylinder 31 includes a housing 311, a handle drive assembly 312, a clutch assembly, and a lever 314. The housing 311 has a mounting groove 311a and a connecting hole 311b communicating with the inner wall of the periphery 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 lever 314 is rotatably mounted in the housing 311 and partially located in the mounting groove 311a. The clutch assembly is movably mounted in the mounting groove 311a and connected to the lever 314. The lever 314 is used to drive the lock body 20 of the smart door lock to perform locking and unlocking operations on the lock body 20.

[0075] The authorization module 32 is installed in the housing 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 an active authorization component 321 and a control component. After obtaining external power, the control component controls the authorization component 321 to enter the mounting slot 311a through the connection 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 after the emergency power supply module 40 of the smart door lock verifies the permissions of the external device, the authorized module 32 can obtain external power through the emergency power supply module 40. After obtaining external power, the control component uses the external power to control the authorized component 321 to enter the mounting slot 311a through the connection hole 311b, so that the handle drive component 312 is linked with the clutch component through the authorized component 321, and thus obtains the permission to operate the emergency unlocking and locking mechanism 30. The user operates 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 toggle block 314 to perform the unlocking and locking operation of the lock body 20. When the authorized component does not receive external power, the handle drive component 312 and the clutch component are in a non-interlocked state, that is, the user does not have the operating authority to operate the emergency unlocking and locking mechanism 30. Operating the handle drive component 312 will not drive the clutch component to move. In this way, when the handle drive component 312 is subjected to external force, it will only rotate freely, which can effectively protect the emergency unlocking and locking mechanism 30 from being damaged by external force.

[0077] It is important to emphasize that the presence of the authorization piece 321 within the mounting slot 311a does not imply that the handle drive assembly 312 is linked to the clutch assembly. In other words, the presence of the authorization piece 321 within the mounting slot 311a does not mean the user has the authority to operate the emergency unlocking mechanism 30. In some examples, the authorization piece 321 is held within the mounting slot 311a by its elasticity, but under slight external force, it can retract through the connection hole 311b and leave the mounting slot 311a. Understandably, the control assembly uses external electrical energy to control the authorization piece 321 to enter the mounting slot 311a through the connection hole 311b. The force applied to the authorization piece 321 by the handle drive assembly 312 and / or the clutch assembly will not cause it to retract through the connection hole 311b, allowing the handle drive assembly 312 to stably link with the clutch assembly via the authorization piece 321. When the control component does not receive power, the license piece 321 may be located in the mounting slot 311a due to external force. However, the force applied to the license piece 321 by the handle drive component 312 or / and the clutch component will cause it to retract into the connection hole 311b, and the handle drive component 312 will not be able to link with the clutch component through the license piece 321.

[0078] The housing 311 is typically provided with a clearance portion that communicates with the mounting groove 311a. The lever 314 is rotatably mounted in the clearance portion. A part of the lever 314 is located in the mounting groove 311a, and the other part of the lever 314 is exposed through the clearance portion and connected to the lock body 20.

[0079] The present invention, through the above-described technical solution, includes a first lock cylinder 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 external power, the control component of the authorization module 32 controls the authorization member 321 to enter the mounting groove 311a through the connecting hole 311b located on the periphery of the mounting groove 311a, so that the handle drive component 312 is linked with the clutch component through the authorization member 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 toggle block 314 to perform the locking and unlocking operation of the lock body 20. As can be seen, compared with the prior art, the technical solution of this application does not require the use of a passive electronic lock cylinder to obtain external power from external devices and to perform identity verification to obtain the authority to operate the emergency unlocking and locking mechanism 30. Furthermore, it does not require manual driving of the rotating component to rotate together with the passive electronic lock cylinder. The emergency unlocking and locking mechanism 30 provided by this application obtains external power through the emergency power supply module 40. The control component controls the authorization component 321 to enter the mounting groove 311a through the connecting hole 311b located on the periphery of the mounting groove 311a. This allows the handle drive component 312 to be linked with the clutch component through the authorization component 321. By operating the handle drive component 312, the user can drive the lever 314 to move, thereby realizing emergency unlocking and locking using the emergency unlocking and locking mechanism 30, which improves the efficiency of emergency unlocking.

[0080] In some examples, such as Figures 3 to 16 As shown, the housing 311 is also provided with a receiving groove 311c communicating with the connecting hole 311b. The authorized module 32 is installed in the receiving groove 311c. The control component includes an elastic component 322, a driving component, and a locking component. The elastic component 322 is elastically installed in the receiving groove 311c and elastically abuts against the authorized component 321 in the mounting groove 311a. The driving component is connected to the locking component to drive the locking component to lock with the elastic component 322, restricting the authorized component 321 from retracting into the connecting hole 311b.

[0081] With this configuration, the authorization piece 321, elastically abutted by the elastic component 322, is positioned within the mounting groove 311a. When the user gains permission to operate the first lock cylinder 31, the drive component drives the locking piece to engage with the elastic component 322, locking the elastic component 322 and preventing relative movement, thus restricting the authorization piece 321 from retracting into the connecting hole 311b. When the user does not gain permission to operate the second lock cylinder, the authorization piece 321, under the force of the handle drive component 312 and the clutch component, can retract into the connecting hole 311b, causing the handle drive component 312 to rotate freely under external force and unable to engage with the clutch component. With the authorization piece 321 elastically abutting against the mounting groove 311a by the elastic component 322, after the control component receives external power, the drive component can quickly drive the locking piece to engage with the elastic component 322, rapidly granting the user permission to operate the second lock cylinder.

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

[0083] The driving component includes a solenoid driver 3231, which is fixedly mounted on the first base 326. The locking component is an iron core 324. The solenoid driver 3231 drives the iron core 324 to engage with the limiting groove 322a through the first clearance hole to restrict the movement of the first top pin 3221.

[0084] With this configuration, the solenoid driver 3231 drives the iron core 324 to engage with the limiting groove 322a through the first clearance hole, which stably restricts the axial movement of the first top pin 3221, thus better limiting the retraction of the authorization piece 321 into the connecting hole 311b. Furthermore, the first spring 3222 elastically supports the first top pin 3221 between the first top pin 3221 and the wall of the first sliding hole 326a. When the user does not have permission to operate the first lock cylinder 31, the authorization piece 321 can elastically press the first top pin 3221 under external force, allowing the authorization piece 321 to elastically retract into the connecting hole 311b.

[0085] In some examples, such as Figures 12 to 16As shown, the authorized module 32 also includes a second base 327, the second base 327 is provided with a second sliding hole 327a, and the elastic component 322 includes a second top pin 3223 and a second spring 3224. The second top pin 3223 is movably installed in the second sliding hole 327a, 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 component includes a motor 3232, which is fixedly mounted on the second base 327. The locking component is an abutment block 325, which is located at the end of the second top pin 3223 away from the authorizing component 321. The abutment block 325 has a clearance surface that avoids the second top pin 3223 and an abutment surface that abuts against the second top pin 3223. The motor 3232 drives the abutment block 325 to rotate, so that the abutment surface abuts against the second top pin 3223 to restrict the movement of the second top pin 3223.

[0087] With this configuration, the abutment block 325 is driven to rotate by the motor 3232, causing the abutment surface to abut against the second top pin 3223. This stably restricts the axial movement of the second top pin 3223, thus better limiting the retraction of the authorization piece 321 into the connecting hole 311b. Furthermore, the second spring 3224 elastically supports the second top pin 3223 between the second sliding hole 327a and the hole wall. When the user does not have permission to operate the second lock cylinder, the authorization piece 321 can elastically press the second top pin 3223 under external force, allowing the authorization piece 321 to elastically retract into the connecting hole 311b.

[0088] In some examples, such as Figures 3 to 16 As shown, the handle drive assembly 312 is provided with a drive groove 312a, and the clutch assembly includes a rotating member 3131. The rotating member 3131 is rotatably mounted in the mounting groove 311a and has a rotating groove 3131a extending through it along its axial direction. The handle drive assembly 312 is at least partially housed in the rotating groove 3131a, and the drive groove 312a is at least partially located in the rotating groove 3131a. The rotating member 3131 is also provided with a locking hole 3131c communicating with the rotating groove 3131a, so that the authorization member 321 abuts against the drive groove 312a through the locking hole 3131c, so that the handle drive assembly 312 is linked with the rotating member 3131 through the authorization member 321.

[0089] With this configuration, one end of the authorization component 321 abuts against the drive groove 312a via the locking hole 3131c, while the other end of the authorization component 321 is constrained by the locking hole 3131c of the mounting groove 311a. Furthermore, the authorization component 321 is prevented from retracting from the connecting hole 311b by the control component, allowing the handle drive assembly 312 to be linked with the rotating component 3131 via the authorization component 321. The user can then rotate the rotating component 3131 by turning the handle drive assembly 312. Additionally, when the authorization component 321 is not within the mounting groove 311a or when it is retracted from the connecting hole 311b by external force, the handle drive assembly 312 can easily rotate relative to the rotating component 3131.

[0090] In some examples, such as Figure 3 and Figure 12 As shown, the handle drive assembly 312 includes a drive shaft 3121 and a handle 316. The handle 316 is fixedly connected to the drive shaft 3121, allowing the user to operate the handle 316 to synchronously drive the drive shaft 3121, thus improving the comfort of operating the smart lock. The drive shaft 3121 is movably mounted in the mounting groove 311a, the handle 316 is exposed in the mounting groove 311a, and the drive groove 312a is formed in the drive shaft 3121.

[0091] In some examples, the circumference of the rotating member 3131 is also recessed with an annular locking groove 3131d, and the housing 311 is provided with a retaining ball assembly. The retaining ball of the retaining ball assembly is engaged with the locking groove 3131d to restrict the movement of the rotating member 3131 along its axial direction. The retaining ball assembly is elastically supported by a spring.

[0092] In some examples, such as Figures 3 to 11 As shown, the drive groove 312a extends axially, and the clutch assembly also includes a first clutch shaft 3132. A first drive part 3132a extends axially around the first clutch shaft 3132. The groove wall of the rotating groove 3131a is also provided with a first mating groove 3131b that is in transmission cooperation with the first drive part 3132a. The paddle block 314 is provided with a connecting groove 314a that communicates with the rotating groove 3131a. The groove wall of the connecting groove 314a is also provided with a second mating groove 314b that can be in transmission cooperation with the first drive part 3132a. The first clutch shaft 3132 is also elastically supported at one end of the handle drive assembly 312 by a first sleeve spring 3133. When the first mating groove 3131b and the second mating groove 314b are aligned, the handle drive assembly 312 can be driven to extend into the connecting groove 314a, elastically squeezing the first clutch shaft 3132 into the connecting groove 314a, so that part of the first drive part 3132a is in transmission cooperation with the second mating groove 314b.

[0093] With this configuration, the drive handle drive assembly 312 extends into the connecting groove 314a to elastically press the first clutch shaft 3132. The drive handle drive assembly 312 drives the rotating part 3131 to rotate at a certain angle. When the first mating groove 3131b on the rotating part 3131 aligns with the second mating groove 314b, the first clutch shaft 3132 enters the connecting groove 314a under the elastic force of the first sleeve spring 3133. This allows part of the first drive part 3132a to engage with the second mating groove 314b, thereby realizing the linkage between the rotating part 3131 and the lever 314.

[0094] In some examples, such as Figures 3 to 11 As shown, the clutch assembly also includes a second clutch shaft 3134, and a second drive part 3134a is provided on the circumference of the second clutch shaft 3134 along its axial direction, which can be driven to cooperate with the second mating groove 314b.

[0095] The first lock cylinder 31 also includes a rear rotating shaft 315, which is rotatably mounted in the mounting groove 311a and located on the side of the lever block 314 away from the rotating member 3131. The rear rotating shaft 315 is provided with a rear shaft groove 315a that communicates with the connecting groove 314a. The groove wall of the rear shaft groove 315a is provided with a third mating groove 315b that is in transmission cooperation with the second drive unit 3134a.

[0096] The second clutch shaft 3134 is also elastically supported in the rear axle groove 315a by the second sleeve springs 3137 and 3135. After the first drive part 3132a of the first clutch shaft 3132 exits the second mating groove 314b and the third mating groove 315b is aligned with the second mating groove 314b, it enters the connecting groove 314a by the elastic force of the second sleeve springs 3137 and 3135, so that part of the second drive part 3134a is in transmission engagement with the second mating groove 314b.

[0097] With this configuration, the rear pivot 315 allows personnel located at the rear of the door to perform locking and unlocking operations on the smart door lock. Specifically, personnel at the rear of the door can operate the emergency locking / unlocking mechanism via the rear pivot 315 to lock and unlock the lock body 20. It is important to emphasize that when personnel at the rear of the door operate the emergency locking / unlocking mechanism 30, there is no need for the authorized module 32 to obtain power from 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 also recessed with two annular grooves 311d. The two annular grooves 311d are also spaced apart along the axial direction of the handle drive assembly 312. A passageway 311e is also provided between the two annular grooves 311d. A limiting protrusion 312b is provided on the periphery of the handle drive assembly 312. The limiting protrusion 312b slides with the annular groove 311d and can enter the other annular groove 311d through the passageway 311e.

[0099] In some examples, a spring is also provided between the handle drive assembly 312 and the rotating member 3131. This is intended to provide elastic potential energy to the handle drive assembly 312, facilitating its axial movement in the direction of separation from the housing 311.

[0100] This design aims to prevent the handle drive assembly 312 from disengaging from the housing 311 when it moves along its axial direction. Furthermore, the annular groove 311d allows for smoother and more stable rotation of the handle drive assembly 312.

[0101] In some examples, such as Figures 12 to 16 As shown, the drive groove 312a extends axially, and the clutch assembly also includes a clutch shaft 3136. A drive part 3136a extends axially from the periphery of the clutch shaft 3136. The groove wall of the rotating groove 3131a is also provided with a first mating groove 3131b that can drive the drive part 3136a. The shift block 314 is provided with a connecting groove 314a communicating with the rotating groove 3131a. The groove wall of the connecting groove 314a is also provided with a second mating groove 314b that drives the drive part 3136a. The first lock cylinder 31 also includes a rear rotating shaft 315. The rear rotating shaft 315 is rotatably mounted in the mounting groove 311a and located on the side of the shift block 314 away from the rotating part 3131. The rear rotating shaft 315 is provided with a rear shaft groove 315a communicating with the connecting groove 314a. The groove wall of the rear shaft groove 315a is provided with a drive part 3136a that can drive the drive part 3136a. The third mating groove 315b, which is in transmission engagement with the drive unit 3136a, and the clutch shaft 3136 are elastically supported on the periphery of the handle drive assembly 312 by two sets of springs 3137. When the first mating groove 3131b and the second mating groove 314b are aligned, the drive handle drive assembly 312 can be moved to elastically press the clutch shaft 3136 into the rotating groove 3131a, so that the drive unit 3136a is in transmission engagement with the first mating groove 3131b and the second mating groove 314b respectively. Alternatively, when the third mating groove 315b and the second mating groove 314b are aligned, the drive handle drive assembly 312 can be moved to elastically press the clutch shaft 3136 into the rear axle groove 315a, so that the drive unit 3136a is in transmission engagement with the third mating groove 315b and the second mating groove 314b respectively.

[0102] With this configuration, the drive handle drive assembly 312 moves axially toward the exit mounting groove 311a, elastically pressing the clutch shaft 3136. The handle 316 assembly drives the rotating component 3131 to rotate a certain angle, so that when the first mating groove 3131b and the second mating groove 314b are aligned, the clutch shaft 3136 enters the rotating groove 3131a under the elastic force of the sleeve spring 3137. This allows the drive part 3136a to engage with the first mating groove 3131b and the second mating groove 314b respectively, thereby realizing the linkage between the rotating component 3131 and the lever 314.

[0103] Compared to the clutch assembly scheme described above, which includes a first clutch shaft 3132 and a second clutch shaft 3134, the scheme in this embodiment is simpler and facilitates the assembly of the emergency unlocking mechanism 30.

[0104] In some examples, such as Figure 12 As shown, the drive shaft 3121 also includes a shaft body and a sub-shaft. A through hole is provided through the shaft body along its axial direction. One end of the sub-shaft is rotatably mounted in 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. A drive groove 312a is provided in the shaft body. This design aims to further reduce the assembly difficulty of the emergency unlocking / locking mechanism 30.

[0105] This application also provides a smart door lock; please refer to the references. Figures 1 to 16 In this embodiment of the invention, the smart door lock includes a master control unlocking and locking mechanism 10, a lock body 20, and the aforementioned emergency unlocking and locking mechanism 30.

[0106] The main control unlocking and locking mechanism 10 includes a second lock cylinder and a panel assembly 11. When the identity verification is successful, the panel assembly 11 can control the second lock cylinder to work, so that the lock body 20 can perform unlocking and locking operations under the operation of the second lock cylinder. The emergency power supply module 40 is used to obtain external power in an emergency, and can provide emergency power to the main control unlocking and locking mechanism 10 or the emergency unlocking and locking mechanism 30 through external power according to the user's needs.

[0107] The panel assembly 11 typically includes two panels, which are respectively installed on the front and rear sides of the door. 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 person performing the unlocking operation. The second lock cylinder is controlled to work only when the panel assembly 11 verifies the identity of the person. The second lock cylinder is not controlled to work when the panel assembly 11 fails to verify the identity of the person.

[0108] In some examples, the second lock cylinder includes a drive structure that is kinetically connected to the bolt 21 of the lock body 20. When the panel assembly 11 controls the second lock cylinder to operate, the drive structure drives the bolt 21 to retract into the lock body 20, thereby achieving the unlocking operation.

[0109] The emergency power supply module 40 can obtain external power in various ways. In one way, the emergency power supply module 40 includes a power supply interface 42, which obtains external power by connecting to an external device. In another way, the emergency power supply module 40 includes a receiving coil, and the external device is equipped with a power supply coil. The emergency power supply module 40 obtains power by utilizing the electromagnetic coupling between the receiving coil and the power supply coil.

[0110] The emergency power supply module 40 can obtain user demand information through wired or wireless means.

[0111] The smart lock provided in this application includes a main control unlocking / locking mechanism 10, a lock body 20, an emergency unlocking / locking mechanism 30, and an emergency power supply module 40. Under normal circumstances, the user can verify their identity information through the panel assembly 11 of the main control unlocking / locking mechanism 10. When the identity verification is successful, the panel assembly 11 controls the second lock cylinder to operate, causing the lock body 20 to perform unlocking / locking operations under the operation of the second lock cylinder. 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 user as needed. The main control unlocking mechanism 10 or the emergency unlocking mechanism 30 can be powered by an emergency power supply. If the main control unlocking mechanism 10 is powered by an emergency power supply, the user can perform the unlocking operation through the normal unlocking method. If the emergency unlocking mechanism 30 is powered by an emergency power supply, the user can authenticate through the emergency power supply module 40. After the authentication is successful, the authorization module 32 obtains external power through the emergency power supply module 40 and then uses the emergency unlocking mechanism 30 to realize the emergency unlocking. This provides users with two different unlocking methods to meet the needs of different users in more scenarios, thereby improving the user experience.

[0112] Furthermore, in the smart door lock provided in this application, the emergency power supply module 40 is first used to obtain external power in an emergency, and then the main control unlocking mechanism 10 or the emergency unlocking mechanism 30 is powered by external power according to user needs. This power supply method can buffer the power supply current of the emergency power supply module 40, thereby avoiding damage to the main control unlocking mechanism 10 and / or the emergency unlocking mechanism 30 by unstable current.

[0113] In some examples, such as Figure 1 and Figure 2 As shown, the emergency power supply module 40 includes a detector 41 and a power supply interface 42. The power supply interface 42 is used to interface with external devices to obtain external power. The detector 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 typically interfaces with smart devices; therefore, the power supply interface 42 includes, but is not limited to, Type-C and Micro-USB, with Type-C being the preferred option, thus expanding the applicability of the smart lock. In some examples, the detector 41 can obtain data information from external devices via the power supply interface 42, allowing users to send request information to the detector 41 through external devices; in some examples, the detector 41 includes a wireless transmission module to obtain user request information wirelessly.

[0115] This configuration allows for a stable electrical connection with external devices via the power supply interface 42, ensuring a stable supply of external power and improving the reliability of the emergency power supply module 40, thereby enhancing the user experience.

[0116] In one embodiment, if the judgment device 41 does not obtain user demand information within a preset time, the judgment device 41 will by default supply the external power obtained from the power supply interface 42 to the main control unlocking mechanism 10 as an emergency power supply.

[0117] Considering that people typically carry mobile phones these days. 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. The data male connector is used to obtain external power from the mobile phone.

[0118] This design aims to further enhance the convenience of using smart locks. When the smart lock runs out of power, users can use their mobile phones to connect to the data connector to provide power to the smart lock.

[0119] In some examples, such as Figure 1 and Figure 2 As shown, the judgment unit 41 also obtains user control commands generated by the mobile phone through the data header, so as to supply the external power obtained by the data header to the main control unlocking mechanism 10 or the emergency unlocking mechanism 30 in accordance with the user control commands.

[0120] With this setup, users can connect their mobile phones to the data connector and send user control commands to the detector 41 via the data connector. Specifically, user control commands can be sent to the detector 41 through WeChat mini programs, apps, quick pop-ups, etc.

[0121] In some examples, such as Figure 1 and Figure 2 As shown, the judge 41 is also used to verify the permissions of the external device that sends the user request information, and after the permission verification is passed, to supply the external power obtained by the power supply interface 42 to the authorized module 32 in an emergency.

[0122] This configuration aims to improve the integration of the smart lock. In some examples, the power supply interface 42 is a data male connector. The detector 41 obtains the user control commands generated by the mobile phone, i.e., user request information, through the data male connector. The detector 41 then verifies the mobile phone's permissions based on these user control commands.

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

[0124] Based on the above, the power supply interface 42 can be a data male connector.

[0125] This configuration is designed to enable users to connect external devices to the power supply interface 42, thereby facilitating data transmission between the external devices and the panel assembly 11 and increasing the authentication methods available to the panel assembly 11, thus providing users with more unlocking options.

[0126] Based on the above smart door locks, please refer to Figure 17 The present invention also proposes an unlocking method, the steps of which include:

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

[0128] Step S2: When a user control command is received, the external power supply is controlled to the emergency unlocking / locking mechanism or the main unlocking / locking mechanism according to the user command, so that the lock body can perform unlocking / locking operations under the operation of the first lock cylinder or the second lock cylinder.

[0129] Step S3: If no user control command is received, the external power supply is directly controlled to supply emergency power to the main control unlocking and locking mechanism so that the lock body can perform unlocking and locking operations under the operation of the second lock cylinder.

[0130] It is understood that the smart lock mentioned in the steps of this method can specifically be the smart lock in the above embodiments. The external devices mentioned in the steps of this method include, but are not limited to, mobile phones, power banks, laptops, and electronic keys, and there can be multiple such external devices. There are two main ways to electrically connect the emergency power supply module mentioned in the steps of this method to the external devices: one is through wire connection, and the other is through electromagnetic coupling of coils.

[0131] The user control commands mentioned in this method are generated by an external device. Specifically, these user control commands are usually generated by the user operating the external device, thereby causing the external device to generate user control commands according to the user's own needs.

[0132] In this way, when the panel components lose power, users can choose to provide emergency power to either the main control unlocking mechanism or the emergency unlocking mechanism according to their own needs to achieve emergency unlocking operation. This dual-channel unlocking method makes the emergency unlocking method not limited to one, improves the unlocking efficiency in emergency situations, and enhances the user experience.

[0133] In one application scenario, the operator (e.g., the user) only has the authentication method of the panel component. The operator can choose to supply external power to the main control unlocking and locking mechanism according to their own situation and needs, so that the lock body can perform unlocking and locking operations under the operation of the first lock cylinder.

[0134] In another application scenario, the operator (e.g., maintenance personnel) does not have an authentication method for the panel components. The operator can choose to supply external power to the emergency unlocking and locking mechanism according to their own situation and needs, so that the lock body can perform unlocking and locking operations under the operation of the first lock cylinder.

[0135] In another application scenario, the operator (e.g., the user) has both the authentication methods of the panel component and the authorization component. The operator can choose to supply external power to the main control unlocking mechanism or the emergency unlocking mechanism according to their own situation and needs, so that the lock body can perform unlocking and locking operations under the operation of the first lock cylinder, or under the operation of the second lock cylinder.

[0136] Please refer to Figure 18 Another embodiment of the unlocking method for smart locks in this invention involves controlling an external power supply to an emergency unlocking / locking mechanism or a main unlocking / locking mechanism according to a user instruction, so that the lock body performs unlocking / locking operations under the operation of the first lock cylinder or the second lock cylinder, including:

[0137] Step S21: When the user control command is a regular unlock command, the external power supply is controlled to supply emergency power to the main control unlocking mechanism, so that the panel assembly can authenticate the user.

[0138] Step S22: If the panel assembly passes authentication, control the second lock cylinder to operate, so that the lock body can perform locking and unlocking operations under the operation of the second lock cylinder.

[0139] Step S23: If the panel component fails to authenticate, it will not control the second lock cylinder to work, so that the lock body cannot perform unlocking and locking operations.

[0140] In this embodiment of the invention, the emergency power supply module controls the external power supply to the main control unlocking mechanism according to the conventional unlocking command. After obtaining sufficient power, the main control unlocking mechanism can operate normally. The panel assembly of the main control unlocking mechanism has multiple unlocking modules that can be used to verify the identity information of the personnel performing the unlocking operation, providing users with conventional unlocking methods.

[0141] Please refer to Figure 19 According to user instructions, the system controls the emergency power supply to the emergency unlocking / locking mechanism or the main unlocking / locking mechanism, so that the lock body can perform unlocking / locking operations under the operation of the first lock cylinder or the second lock cylinder, including:

[0142] Step S24: When the user control command is an emergency unlock command, further authorization verification is performed on the device that issued the user control command.

[0143] Step S25: If the authorization verification is successful, the external power supply is controlled to the emergency unlocking and locking mechanism, so that after the authorized module obtains the external power, it controls the authorized component to link the handle drive component and the clutch component, thereby enabling the lock body to perform unlocking and locking operations under the operation of the first lock cylinder.

[0144] Step S26: If the authorization verification fails, the external power supply to the emergency unlocking and locking mechanism will be stopped, so that the lock body cannot perform unlocking and locking operations.

[0145] In this embodiment of the invention, the emergency power supply module controls the external power supply to the emergency unlocking mechanism according to the emergency unlocking command. After obtaining the external power, the control component of the authorization module controls the authorization piece to enter the mounting slot through the connection hole located on the periphery of the mounting slot, so that the handle drive component is linked with the clutch component through the authorization piece. The power source for its unlocking operation mainly depends on the user's operation of the handle drive component. Therefore, the power requirement for unlocking and locking the smart door lock through the emergency unlocking mechanism is low, and rapid emergency unlocking can be achieved.

[0146] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
