Description

Technical Field

[0001] The present invention relates to the technical field of intelligent locks, and particularly to a calibration method for an intelligent lock and an intelligent lock. Background Art

[0002] For traditional mechanical door locks, people need to manually open the door lock with a key. To improve the user's door-opening experience, an intelligent lock mechanism has emerged. By installing this intelligent lock mechanism on the lock body (door lock) of the door, the intelligent lock mechanism can be automatically unlocked and locked through remote control by devices such as mobile phones. After installing the intelligent lock on the door lock of the door, it is necessary to calibrate the intelligent lock for positions such as controlling the unlocking and / or locking of the door lock. After calibration, precise control of the unlocking and locking of the door lock can be achieved through the intelligent lock. Existing intelligent locks usually require users to manually calibrate, which is rather cumbersome and not intelligent enough. Summary of the Invention

[0003] The main technical problem to be solved by the present invention is to improve the efficiency and intelligence of the calibration of the intelligent lock by automatically calibrating the intelligent lock, which will be specifically described below.

[0004] According to a first aspect, in one embodiment, a calibration method for an intelligent lock is provided, which is applied to the intelligent lock. The intelligent lock includes a lock claw mechanism and a driving mechanism, and the driving mechanism is used to apply a force to the lock claw mechanism to drive the lock claw mechanism to rotate. When the intelligent lock is installed on the door, the lock claw mechanism of the intelligent lock can cooperate with the operation part of the door lock installed on the door, so that when the lock claw mechanism is driven to rotate by the driving mechanism, the door lock can be synchronously driven to rotate to achieve locking and unlocking. The calibration method includes:

[0005] In response to a calibration instruction, apply a force to the lock claw mechanism through the driving mechanism to drive the lock claw mechanism to rotate in a first direction;

[0006] After the lock claw mechanism rotates to its limit position in the first direction, control the driving mechanism to stop applying a force to the lock claw mechanism. Thus, the lock claw mechanism rotates in a second direction and stops without being applied a force by the driving mechanism, and obtain the stopped position as a first reference position; wherein the first direction and the second direction are opposite;

[0007] Take the first reference position as the calibrated first automatic locking position, and take the first direction as the automatic locking direction and the second direction as the automatic unlocking direction;

[0008] Alternatively, take the first reference position as the calibrated first automatic unlocking position, and take the first direction as the automatic unlocking direction and the second direction as the automatic locking direction.

[0009] According to a second aspect, in one embodiment, a calibration method for an intelligent lock is provided, which is applied to the intelligent lock. The intelligent lock includes a locking claw mechanism and a driving mechanism, and the driving mechanism is used to apply a force to the locking claw mechanism to drive the locking claw mechanism to rotate. When the intelligent lock is installed on a door, the locking claw mechanism of the intelligent lock can cooperate with an operating part of a door lock installed on the door, so that when the locking claw mechanism is driven to rotate by the driving mechanism, the door lock can be synchronously driven to rotate to lock and unlock the door. The calibration method includes:

[0010] In response to a calibration instruction, apply a force to the locking claw mechanism through the driving mechanism to drive the locking claw mechanism to rotate in a second direction;

[0011] After the locking claw mechanism rotates in the second direction to its limit position of rotation, control the driving mechanism to stop applying a force to the locking claw mechanism. Thus, the locking claw mechanism rotates in a first direction and stops without being applied a force by the driving mechanism, and obtain the stopped position as a second reference position. The first direction and the second direction are opposite;

[0012] Take the second reference position as the calibrated first automatic locking position, and take the second direction as the automatic locking direction, and the first direction as the automatic unlocking direction;

[0013] Alternatively, take the second reference position as the calibrated first automatic unlocking position, and take the second direction as the automatic unlocking direction, and the first direction as the automatic locking direction.

[0014] According to a third aspect, in one embodiment, an intelligent lock is provided. The intelligent lock includes a locking claw mechanism and a driving mechanism, and the driving mechanism is used to apply a force to the locking claw mechanism to drive the locking claw mechanism to rotate. When the intelligent lock is installed on a door, the locking claw mechanism of the intelligent lock can cooperate with an operating part of a door lock installed on the door, so that when the locking claw mechanism is driven to rotate by the driving mechanism, the door lock can be synchronously driven to rotate to lock and unlock the door. The intelligent lock further includes:

[0015] A processor, configured to execute the calibration method described in the first aspect above, or execute the calibration method described in the second aspect above.

[0016] The calibration method for the intelligent lock and the intelligent lock according to the above embodiments realize a way to automatically calibrate the intelligent lock, improving the efficiency and intelligence level of the intelligent lock calibration;

[0017] And according to the calibration method and intelligent lock of the above embodiments, after applying a force to the lock claw mechanism through the driving mechanism to drive the lock claw mechanism to rotate to its limit position of rotation, the driving mechanism is controlled to stop applying a force to the lock claw mechanism. Thus, the lock claw mechanism rotates in the second direction and stops without being forced by the driving mechanism, and the position where the driving mechanism stops is obtained, so that the subsequent position can be used as the automatic locking position or automatic unlocking position of the intelligent lock, avoiding the impact on the structure of the intelligent lock and / or the door lock when the intelligent lock drives the door lock to lock or unlock according to the automatically calibrated position, thereby avoiding damage to the intelligent lock and / or the door lock.

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners adopt related similar element numbers. In the following implementation manners, many details are described to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods.

For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0033] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean a necessary sequence unless it is stated that a certain sequence must be followed.

[0034] As used in this application, "connection" and "coupling", unless otherwise specified, both include direct and indirect connection (coupling).

[0035] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. In particular, for the first direction and the second direction mentioned herein, they are used to distinguish different described objects. The first direction can be renamed as the second direction, and the original second direction can be renamed as the first direction.

[0036] Please refer to Figure 1, in some embodiments, an intelligent lock 10 is disclosed. The intelligent lock 10 includes a lock claw mechanism 11 and a driving mechanism 12, and the driving mechanism 12 can be a driving motor; the driving mechanism 12 is configured to apply a force to the lock claw mechanism 11 to drive the lock claw mechanism 11 to move, and the movement can be a rotational movement, that is, the driving mechanism 12 is configured to apply a force to the lock claw mechanism 11 to drive the lock claw mechanism 11 to rotate. In some examples, the driving mechanism 12 can apply a force to the lock claw mechanism 11 to drive the lock claw mechanism 11 to rotate in one or more directions. For example, the driving mechanism 12 can apply a force to the lock claw mechanism 11 to drive the lock claw mechanism 11 to rotate in the first direction or along the first direction. For another example, the driving mechanism 12 can apply a force to the lock claw mechanism 11 to drive the lock claw mechanism 11 to rotate in the second direction or along the second direction; in some examples, the first direction and the second direction are opposite. For example, if the first direction is the clockwise rotation direction, then the second direction is the counterclockwise rotation direction. Similarly, if the first direction is the counterclockwise rotation direction, then the second direction is the clockwise rotation direction. The intelligent lock 10 can be locked and unlocked by rotating the lock claw mechanism 11 in different directions. For example, the first direction mentioned in this article can be the unlocking direction, that is, when the driving mechanism 12 applies a force to the lock claw mechanism 11 to drive the lock claw mechanism 11 to rotate in the first direction, the unlocking effect can be finally achieved. Correspondingly, the second direction is the locking direction, that is, when the driving mechanism 12 applies a force to the lock claw mechanism 11 to drive the lock claw mechanism 11 to rotate in the second direction, the locking effect can be finally achieved. For another example, the first direction mentioned in this article can also be the locking direction, that is, when the driving mechanism 12 applies a force to the lock claw mechanism 11 to drive the lock claw mechanism 11 to rotate in the first direction, the locking effect can be finally achieved. Correspondingly, the second direction is the unlocking direction, that is, when the driving mechanism 12 applies a force to the lock claw mechanism 11 to drive the lock claw mechanism 11 to rotate in the second direction, the unlocking effect can be finally achieved, which will be further described below.

[0037] Please refer to Figure 2, in some embodiments, the smart lock 10 may further include a processor 19; in some embodiments, the processor 19 may be implemented by at least one of a circuit, a single or multiple application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), central processing units (CPUs), controllers, microcontrollers, and microprocessors; in some embodiments, the processor 19 may execute some steps, all steps, or any combination of the steps in the calibration method of the smart lock in each of the embodiments mentioned herein, which will be further described in detail below.

[0038] Please refer to Figure 3 , in some embodiments, the smart lock 10 may further include a communication component 13. In some embodiments, the communication component 13 is used to communicate with a terminal having communication functions such as wireless communication functions, and the terminal may be a smart phone or the like. The smart lock 10 can receive instructions issued by the terminal through the communication component 13 and execute relevant instructions, and the instructions may be, for example, a locking instruction, an unlocking instruction, and the calibration instruction mentioned herein. For example, the user can issue an unlocking instruction to the smart lock 10 by operating the terminal. After the processor 19 receives the unlocking instruction through the communication component 13, in response to the unlocking instruction, the processor 19 drives the lock claw mechanism 11 to rotate in the unlocking direction through the driving mechanism 12 to achieve unlocking. For another example, the user can issue a locking instruction to the smart lock 10 by operating the terminal. After the processor 19 receives the locking instruction through the communication component 13, in response to the locking instruction, the processor 19 drives the lock claw mechanism 11 to rotate in the locking direction through the driving mechanism 12 to achieve locking. For another example, the user can issue a calibration instruction to the smart lock 10 by operating the terminal. After the processor 19 receives the calibration instruction through the communication component 13, in response to the calibration instruction, the processor 19 drives the lock claw mechanism 11 to rotate accordingly to execute some steps, all steps, or any combination of the steps in the calibration method of the smart lock in each of the embodiments mentioned herein. By introducing the communication component 13, the smart lock 10 can be locked and unlocked in a way other than using a traditional key. For example, the user can lock and unlock through the terminal, which is very convenient.

[0039] Please refer to Figure 4 andFigure 5 , Figure 4 is a three-dimensional schematic diagram of the smart lock 10, Figure 5 It is a partial schematic diagram of the smart lock 10, which removes the relevant external shell to facilitate the observation of the structure of components such as the drive mechanism 12. The smart lock 10 of this article can be installed on a door, especially on one side inside the door; in order to further facilitate the user to lock or unlock the door inside, in some embodiments, the smart lock 10 may also include a rotating member 14; wherein the smart lock 10 has a mounting surface and another side opposite to the mounting surface, and the mounting surface of the smart lock 10 can be connected to the door by bonding or screwing, so that the smart lock 10 is fixed to the door through the mounting surface, and the rotating member 14 is arranged on the other side of the smart lock 10 opposite to the mounting surface for manual rotation by the user; in some examples, the rotating member 14 is connected to the pawl mechanism 11 in transmission connection, for example, through a transmission gear assembly 15, so that when the user rotates the rotating member 14, the pawl mechanism 11 can be driven to rotate in the corresponding direction, thereby achieving locking or unlocking.

[0040] The above is some description of the smart lock 10.

[0041] The smart lock 10 can be installed on a door. When the smart lock 10 is installed on a door, the smart lock 10 can cooperate with the door lock on the door to achieve locking and unlocking. Locking refers to locking the door, which is commonly known as closing the door or shutting the door, and unlocking refers to opening the door or opening the door. Before specifically explaining how the smart lock 10 cooperates with the door lock on the door to achieve locking and unlocking, first explain how the door lock on the door itself locks and unlocks the door.

[0042] Please refer to Figure 6 In some embodiments, the door lock 20 includes a lock body 21 and a lock tongue 22; the door is locked and unlocked by extending the lock tongue 22 from the lock body 21 of the door lock 20 or retracting the lock tongue 22 into the lock body 21, wherein Figure 6The state diagram on the left in the figure shows a schematic diagram of the lock tongue 22 extending out of the lock body 21, and the state diagram on the right shows a schematic diagram of the lock tongue 22 retracting into the lock body 21. Of course, the structure of the door lock 20 in this article is not limited to this, and the door lock with a lock tongue structure is only for example. In some embodiments, the door lock 20 may further include an operation part 23. The operation part 23 may refer to a component for the user to operate to lock and unlock the door. Typically, when the smart lock 10 is not installed on the door, the user can lock and unlock the door by operating the operation part 23 of the door lock 20, that is, closing and opening the door; the operation part 23 of the door lock may be, for example, a knob-type structure, and the user manually rotates the operation part 23 to lock and unlock the door. It can be understood that the operation part 23 is connected to the lock tongue 22 through relevant force conduction structures. When the user operates the operation part 23 (such as rotating the operation part 23), it is essentially applying an active force to the operation part 23. This applied force ultimately causes the lock tongue 22 to be actively forced through the above-mentioned relevant force conduction structures. Thus, the user can operate the operation part 23 to make the lock tongue 22 extend out of or retract into the lock body 21 of the door lock 20.

[0043] Different lock tongue structures will also result in different types of door locks. In some embodiments, please refer to Figure 7 , the lock tongue 22 of the door lock 20 includes a bolt 22a but does not include a deadbolt 22b. This type of door lock may be referred to as the first type of door lock 20. In some embodiments, please refer to Figure 8 , the lock tongue 22 of the door lock 20 includes a bolt 22a and a deadbolt 22b. This type of door lock may be referred to as the second type of door lock 20. In some examples, the difference between the bolt 22a and the deadbolt 22b is that the deadbolt 22b is in a pending position outside the lock body 21 of the door lock 20 in the normal state, for example, when not actively forced. And when actively forced by an external force, it will retract into the lock body 21 of the door lock 20 from the above-mentioned pending position outside the lock body to complete unlocking. When the above-mentioned active applied force disappears, the deadbolt 22b will bounce back to the above-mentioned pending position; while the bolt 22a generally does not have the above-mentioned bouncing-back function, that is, the bolt 22a needs to be actively forced by an external force to extend from the lock body 21 of the door lock 20 to the outside of the lock body 21 of the door lock 20, and also needs to be actively forced by an external force to retract from the outside of the lock body 21 of the door lock 20 to the lock body 21 of the door lock 20.

[0044] Next, a specific description will be given on how the two types of door locks achieve locking and unlocking.

[0045] In some embodiments, the first type of door lock 20 locks and unlocks by means of a latch 22a. Generally, during the locking process, the latch 22a can be actively forced by an external force to extend from within the lock body 21 of the door lock 20 to outside the lock body 21 of the door lock 20, thereby achieving locking. During the unlocking process, the latch 22a can be actively forced to retract from outside the lock body 21 of the door lock 20 into the lock body 21, thereby achieving unlocking.

[0046] In some embodiments, the second type of door lock 20 locks and unlocks jointly by means of a latch 22a and a deadbolt 22b. The deadbolt 22b is used to retract into the lock body 21 of the door lock 20 from a pending position (which may be referred to as the first pending position, for example, a position extending outside the lock body 21) in a manner driven by an external force when the door lock 20 is unlocked to complete the unlocking, and will rebound to the above-mentioned pending position after the unlocking action is completed. It can be understood that this describes the state change of the deadbolt 22b during the unlocking process. During the unlocking process, the latch 22a will also have a corresponding state change: the latch 22a also retracts into the lock body 21 of the door lock 20 from a pending position (which may be referred to as the second pending position, for example, a position extending outside the lock body 21) in a manner driven by an external force when the door lock 20 is unlocked. When both the latch 22a and the deadbolt 22b retract into the lock body 21 of the door lock 20, the door lock 20 completes the unlocking and the door is opened. Similarly, when the door lock 20 is locked, at least one of the latch 22a and the deadbolt 22b extends outside the lock body 21 of the door lock 20.

[0047] The above is some description of how the door lock 20 on the door itself locks and unlocks the door. Next, an explanation will be given on how the smart lock 10 cooperates with the door lock 20 on the door to achieve locking and unlocking.

[0048] In some embodiments, the smart lock 10 can cooperate with the door lock 20 on the door to achieve locking and unlocking, which can be specifically achieved through the cooperation between the locking claw mechanism 11 of the smart lock 10 and the operation part 23 of the door lock 20. For example, when the smart lock 10 is installed on the door, the locking claw mechanism 11 of the smart lock 10 can cooperate with the operation part 20 of the door lock 20 installed on the door, so that when the locking claw mechanism 11 moves, it can synchronously drive the door lock 20 to move to achieve locking and unlocking. Taking the movement of the locking claw mechanism 11 as an example of rotation, the locking claw mechanism 11 of the smart lock 10 can cooperate with the operation part 23 of the door lock 20 installed on the door, so that when the locking claw mechanism 11 rotates, it can synchronously drive the operation part 23 of the door lock 20 to rotate to achieve locking and unlocking.

[0049] As can be seen, in some embodiments, for the smart lock 10, since the locking and unlocking are achieved through the cooperation between its locking claw mechanism 11 and the operating part 23 of the door lock 20, the smart lock 10 has universality and can be adapted to the vast majority of doors and door locks. During the installation process, it only needs to install the smart lock 10 on the door lock 20 of the door so that the smart lock 10 and the operating part 23 of the door lock 20 can achieve the above-mentioned cooperation. The installation is convenient and there is no need to replace the door or the door lock.

[0050] The above are some descriptions of the smart lock 10, the door lock 20, and how the two cooperate.

[0051] After installing the smart lock 10 on the door, it is necessary to calibrate the position of the smart lock 10 for controlling the unlocking and / or locking of the door lock 20. After calibration, precise control of the unlocking and locking of the door lock 20 can be achieved through the smart lock 10. Existing smart locks 10 usually require manual intervention by the user to continuously debug for calibration, which is rather cumbersome and not intelligent enough.

[0052] Some embodiments of the present application provide a calibration method for a smart lock. The smart lock targeted by the calibration method can be the smart lock 10 disclosed in some embodiments herein, or other smart locks applicable to the calibration method herein, which is determined by the applicable situations of the steps of the calibration method itself.

[0053] Please refer to Figure 9 and Figure 10 , the calibration method 101 of some embodiments includes the following steps:

[0054] Step 110: In response to a calibration instruction, apply a force to the locking claw mechanism through a driving mechanism to drive the locking claw mechanism to rotate in a first direction.

[0055] In some embodiments, in step 110, it can be that when the locking claw mechanism 11 is in a first state position, apply a force to the locking claw mechanism 11 through the driving mechanism 12 to drive the locking claw mechanism 11 to rotate from the first state position in the first direction. The first state position can be the manual unlocking position or the manual locking position of the smart lock 10, that is, the unlocking position or the locking position corresponding to the door lock 20.

[0056] Among them, the manual unlocking position or the manual locking position is the unlocking position or the locking position of the smart lock 10 confirmed manually by the user. For example, the user can be first prompted by a terminal such as a smart phone to manually rotate the locking claw mechanism 11 to the unlocking position or the locking position. An operation APP corresponding to the smart lock 10 is installed on the smart phone. The operation APP prompts the user to manually rotate the locking claw mechanism 11 to the unlocking or locking position. If the user confirms that the locking claw mechanism 11 is not currently in the first state position, after the user manually rotates the rotating member 14 to rotate the locking claw mechanism 11 to the unlocking or locking position, a confirmation instruction is sent to the smart lock 10 through the operation APP, so that the driving mechanism 12 applies a force to the locking claw mechanism 11 to drive the locking claw mechanism 11 to rotate in the first direction; if the user confirms that the locking claw mechanism 11 is currently in the first state position, the user can directly send a confirmation instruction to the smart lock 10 through the operation APP, so that the driving mechanism 12 applies a force to the locking claw mechanism 11 to drive the locking claw mechanism 11 to rotate in the first direction.

[0057] In this embodiment, by applying a force to the locking claw mechanism 11 through the driving mechanism 12 to drive the locking claw mechanism 11 to rotate from the first state position in the first direction, the automatic unlocking position and the automatic locking position of the smart lock 10 can be confirmed more accurately.

[0058] In some embodiments, in step 110, it may also be that when the locking claw mechanism 11 is in any position, a force is applied to the locking claw mechanism 11 through the driving mechanism 12 to drive the locking claw mechanism 11 to rotate from any position in the first direction.

[0059] Step 120: Determine the first reference position.

[0060] Specifically, in step 120, after the locking claw mechanism 11 rotates in the first direction to its rotation limit position, the driving mechanism 12 is controlled to stop applying a force to the locking claw mechanism 11. Thus, the locking claw mechanism 11 rotates in the second direction and stops without being applied a force by the driving mechanism 12, and the position where the driving mechanism 12 stops is obtained as the first reference position; wherein, the first direction and the second direction are opposite.

[0061] Among them, regarding the rotation limit position of the locking claw mechanism 11, when the lock tongue 22 completely extends out of the lock body 21 of the door lock 20 or the lock tongue 22 completely retracts into the lock body 21, the operation part 23 of the door lock 20 cannot rotate anymore. Therefore, the driving mechanism 12 cannot drive the locking claw mechanism 11 to rotate anymore. At this time, the position of the locking claw mechanism 11 is its rotation limit position.

[0062] After the locking claw mechanism 11 rotates to its rotation limit position in the first direction (which may be called the limit position A1), the driving mechanism 12 stops applying force to the locking claw mechanism 11. At this time, the locking claw mechanism 11 will rotate in the second direction due to the structural elastic deformation of the intelligent lock 10 and / or the door lock 20 without the force applied by the driving mechanism 12 and stop at a certain position after reaching it. This position is the position expected to be obtained in step 120, that is, the first reference position.

[0063] It should be noted that the structural elastic deformation of the intelligent lock 10 and / or the door lock 20 includes the deformation of the structural components inside the door lock 20 under the action of the force applied by the driving mechanism 12, the deformation of the structural components inside the intelligent lock 10 under the reaction force of the door lock 20, the deformation of the connection between the intelligent lock 10 and the door (i.e., the connection between the installation surface of the intelligent lock 10 and the door) under the action of the force applied by the driving mechanism 12, etc.

[0064] Optionally, the intelligent lock 10 further includes a locking claw state detection module (such as a rotary encoder). The locking claw state detection module is connected to the main control chip of the intelligent lock 10 and is used to output a detection signal to the main control chip when detecting that the locking claw mechanism 11 rotates the operating part 23 of the door lock 20, so that the main control chip can obtain the rotation angle and rotation direction of the locking claw mechanism 11 according to the detection signal.

[0065] Further, obtaining the position where the locking claw mechanism 11 stops as the first reference position may include: the main control chip obtains the rotation angle when the locking claw mechanism 11 stops according to the detection signal of the locking claw state detection module. This rotation angle is the rotation angle of the locking claw mechanism 11 rotating from the first direction to the position where the locking claw mechanism 11 stops, and the corresponding angular position of the locking claw mechanism 11 at this time is used as the first reference position.

[0066] It should be noted that the first rotation angle, the second rotation angle, the third rotation angle, the fourth rotation angle, and the fifth rotation angle mentioned later can all detect the rotation angle of the locking claw mechanism 11 by using the locking claw state detection module; the second reference position and the third reference position mentioned later can also be obtained according to the detection signal of the locking claw state detection module.

[0067] Step 130: Determine at least the first automatic locking position or the first automatic unlocking position.

[0068] For example, step 130 takes the first reference position as the calibrated first automatic locking position, and step 130 also takes the first direction as the automatic locking direction and the second direction as the automatic unlocking direction. Or, for example, step 130 takes the first reference position as the calibrated first automatic unlocking position, and step 130 also takes the first direction as the automatic unlocking direction and the second direction as the automatic locking direction.

[0069] Among them, the first automatic locking position corresponds to the locking position of the locking tongue 22 of the door lock 20 (i.e., the position where the locking tongue 22 extends out of the lock body 21); specifically, if the type of the door lock is the first type of door lock, the first automatic locking position corresponds to the locking position of the latch 22a of the door lock 20 (i.e., the position where the latch 22a extends out of the lock body 21), and if the type of the door lock is the second type of door lock, the first automatic locking position corresponds to the locking positions of the latch 22a and the oblique tongue 22b of the door lock 20 (i.e., the positions where the latch 22a and the oblique tongue 22b extend out of the lock body 21).

[0070] The first automatic unlocking position corresponds to the unlocking position of the locking tongue 22 of the door lock 20 (i.e., the position where the locking tongue 22 retracts into the lock body 21); specifically, if the type of the door lock is the first type of door lock, the first automatic unlocking position corresponds to the unlocking position of the latch 22a of the door lock 20 (i.e., the position where the latch 22a retracts into the lock body 21), and if the type of the door lock is the second type of door lock, the first automatic unlocking position corresponds to the unlocking position of the latch 22a of the door lock 20 (i.e., the position where the latch 22a retracts into the lock body 21).

[0071] In some embodiments, when in step 110, the driving mechanism 12 applies a force to the locking claw mechanism 11 to drive the locking claw mechanism 11 to rotate from the first state position in the first direction, in step 130, if the first state position is the manual unlocking position of the smart lock 10, the first reference position is taken as the calibrated first automatic locking position, the first direction is taken as the automatic locking direction, and the second direction is taken as the automatic unlocking direction; if the first state position is the manual locking position of the smart lock 10, the first reference position is taken as the calibrated first automatic unlocking position, the first direction is taken as the automatic unlocking direction, and the second direction is taken as the automatic locking direction.

[0072] It should be noted that since the locking claw mechanism 11 rotates from the first state position in the first direction to the first reference position, therefore, when the first state position is the manual unlocking position of the smart lock 10, the first reference position can be taken as the first automatic locking position. Further, the rotation direction from the manual unlocking position to the first automatic locking position (i.e., the first direction) is taken as the automatic locking direction. Since the locking and unlocking directions of the smart lock and the door lock are opposite directions, the second direction can be taken as the automatic unlocking direction; or, when the first state position is the manual locking position of the smart lock 10, the first reference position can be taken as the first automatic unlocking position. Further, the rotation direction from the manual locking position to the first automatic unlocking position (i.e., the first direction) is taken as the automatic unlocking direction. Since the locking and unlocking directions of the smart lock and the door lock are opposite directions, the second direction can be taken as the automatic locking direction.

[0073] After determining the calibrated first automatic locking position or first automatic unlocking position, the automatic locking direction, and the automatic unlocking direction, if the user issues a locking instruction through, for example, a smart phone, the processor 19 of the smart lock 10 can control the driving mechanism 12 to drive the locking claw mechanism 11 to rotate in the first direction to the first automatic locking position to perform automatic locking; or, if the user issues an unlocking instruction through, for example, a smart phone, the processor 19 of the smart lock 10 can control the driving mechanism 12 to drive the locking claw mechanism 11 to rotate in the first direction to the first automatic unlocking position to perform automatic unlocking.

[0074] In steps 110 - 130, by using the first reference position instead of the limit position A1 as the calibrated first automatic locking position or first automatic unlocking position, not only can the precise control of locking the door lock 20 be achieved, but also since the locking position or unlocking position is not the limit position A1, when the smart lock 10 performs automatic unlocking or automatic locking, that is, there is no need to rotate the locking claw mechanism 11 to the limit position of its rotation in the locking direction or unlocking direction. This can not only increase the service life of the smart lock 10 and / or the door lock 20, but also reduce the risk of the mounting surface of the smart lock 10 detaching from the door.

[0075] It should be noted that usually, both the smart lock 10 and the door lock 20 have relevant industry standards, which enables the smart lock 10 to preset and know which direction of rotation is the locking direction and which direction of rotation is the unlocking direction; and, to conform to user habits, the locking directions of most door locks 20 are the same, and the unlocking directions of most door locks 20 are the same, that is, the automatic locking directions of most smart locks 10 are the same, and the automatic unlocking directions of most smart locks 10 are the same.

[0076] However, there are still some cases where, due to the differences in door locks 20 in various countries, the locking directions and unlocking directions of door locks 20 in different countries are not the same. Therefore, in the case where the smart lock 10 does not know which direction is the locking direction and which direction of rotation is the unlocking direction, it is necessary to confirm the automatic locking direction and automatic unlocking direction of the smart lock 10. Please refer to Figure 11 , in the calibration method 101 of some embodiments, after step 120 and before step 130, the following steps are further included:

[0077] Step 122: Apply a force to the locking claw mechanism through the driving mechanism to drive the locking claw mechanism to rotate from the first reference position in the second direction.

[0078] Step 124: Determine the second reference position.

[0079] Specifically, in step 124, after the locking claw mechanism 11 rotates from the first reference position to the second direction to its rotation limit position (which may be called the limit position B1), the control drive mechanism 12 stops applying force to the locking claw mechanism 11. Thus, the locking claw mechanism 11 rotates in the first direction and stops without being forced by the drive mechanism 12, and the position where the drive mechanism 12 stops is obtained as the second reference position.

[0080] It should be specifically noted that in Figure 10 , the clockwise rotation direction is the first direction, and the counterclockwise rotation direction is the second direction. This is only for illustration and is not used to limit that the first direction can only be the clockwise rotation direction and the second direction can only be the counterclockwise rotation direction. And Figure 10 shows the positional relationship among the limit position B1, the second reference position, and the first state position. Generally, in the figure, the first state position and the second reference position are located on the right side of the limit position B1. However, the positional relationship between the second reference position and the first state position is determined according to the actual situation. Although the figure shows that the first state position is on the right side of the second reference position, this is only for illustration. In actual situations, the first state position may also be on the left side of the second reference position, or the first state position and the second reference position may be the same position. In addition, Figure 10 the position marked by the solid dot in

[0081] is the initial position during calibration.

[0082] In the case where the first state position corresponds to the manual unlocking position, in some examples, if the door lock 20 is of the first type, then in step 124, the locking claw mechanism 11 rotates in the first direction due to the structural elastic deformation of the intelligent lock 10 and / or the door lock 20 without being forced by the drive mechanism 12. In some examples, if the door lock 20 is of the second type, then in step 124, the locking claw mechanism 11 rotates in the first direction due to the drive of the operating part 23 of the door lock 20 and the structural elastic deformation of the intelligent lock 10 and / or the door lock 20 without being forced by the drive mechanism 12.

[0083] More specifically, when the first status bit corresponds to the manual unlocking position, if the door lock 20 is of the first type, in step 124, after the locking pawl mechanism 11 rotates from the first reference position to the second direction to its rotation limit position, i.e., limit position B1, the control drive mechanism 12 stops applying force to the locking pawl mechanism 11. At this time, the locking pawl mechanism 11 will rotate in the first direction due to the structural elastic deformation of the intelligent lock 10 and / or the door lock 20 without the force applied by the drive mechanism 12, and finally stop at a certain position after reaching it. This position is the second reference position. If the door lock 20 is of the second type, as previously described, its oblique tongue 22b will be retracted into the lock body 21 of the door lock 20 by a driving method to complete unlocking when the door lock 20 is unlocked, and will rebound to the above-mentioned first undetermined position after the unlocking action is completed. Therefore, in step 124, after the locking pawl mechanism 11 rotates from the first reference position to the second direction to its rotation limit position, i.e., limit position B1, the control drive mechanism 12 stops applying force to the locking pawl mechanism 11. At this time, the oblique tongue 22b will automatically rebound to the first undetermined position, and during this process, it will drive the operating part 23 on the door lock 20 to rotate in the first direction, so that the locking pawl mechanism 11 rotates in the first direction due to the drive of the operating part 23 of the door lock 20 and the structural elastic deformation of the intelligent lock 10 and / or the door lock 20 without the force applied by the drive mechanism 12, and finally stop at a certain position after reaching it. This position is the second reference position.

[0084] Step 126: Determine the calibrated first automatic locking position or the first automatic unlocking position according to the first status bit, the first reference position, and the second reference position.

[0085] In some embodiments, in step 126, it is determined whether the first angle difference between the first rotation angle when the locking pawl mechanism 11 rotates from the first status bit to the first reference position and the second rotation angle when the locking pawl mechanism 11 rotates from the first reference position to the second reference position is not greater than a preset angle difference threshold; if the first angle difference is not greater than the angle difference threshold, then in step 130, when the first status bit corresponds to the manual unlocking position, the first reference position is used as the calibrated first automatic locking position, and the first direction can be used as the automatic locking direction, and the second direction can be used as the automatic unlocking direction; or, if the first angle difference is not greater than the angle difference threshold, then in step 130, when the first status bit corresponds to the manual locking position, the first reference position is used as the calibrated first automatic unlocking position, and the first direction can be used as the automatic unlocking direction, and the second direction can be used as the automatic locking direction.

[0086] Among them, the preset angle difference threshold is set according to manual experience, for example, it can be any one of 0° to 30°.

[0087] It should be noted that since the rotation angles of the intelligent lock 10 in the unlocking direction and the locking direction are the same or close, the accuracy of the calibration direction can be determined by the magnitude relationship between the first angle difference between the first rotation angle and the second rotation angle and the angle difference threshold. If the first angle difference is not greater than the angle difference threshold, it can be indicated that the calibration direction is correct. In the case of a correct calibration direction, the first reference position can be used as the calibrated first automatic unlocking position or the first automatic locking position.

[0088] In some embodiments, if it is determined in step 126 that the first angle difference is greater than the angle difference threshold, the driving mechanism 12 applies a force to the locking claw mechanism 11 to drive the locking claw mechanism 11 to rotate in the first direction from the second reference position; after the locking claw mechanism 11 rotates from the second reference position to its rotation limit position in the first direction, the driving mechanism 12 is controlled to stop applying a force to the locking claw mechanism 11, so that the locking claw mechanism 11 rotates in the second direction and stops without being applied a force by the driving mechanism 12, and the position where the driving mechanism 12 stops is obtained as the third reference position; the calibrated first automatic locking position or the first automatic unlocking position is determined according to the first reference position, the second reference position, and the third reference position.

[0089] In some embodiments, if it is determined in step 126 that the first angle difference is greater than the angle difference threshold, the intelligent lock 10 can also be controlled to stop calibration and a prompt for an error is given to the user.

[0090] It should be noted that if the first angle difference is greater than the angle difference threshold, it can be indicated that the calibration direction is incorrect. In the case of an incorrect calibration direction, the locking claw mechanism 11 can be driven to rotate once more in the direction opposite to the previous rotation to make the calibration direction correct; or a prompt can be given to the user so that the user can handle the situation of an incorrect calibration direction.

[0091] It should be noted that the first rotation angle when the locking claw mechanism 11 rotates from the first state position to the first reference position is a concept of an absolute angle, which refers to the stroke angle required for the locking claw mechanism 11 to directly rotate from the first state position to the first reference position in the first direction, rather than the stroke angle required for the locking claw mechanism 11 to rotate from the first state position to the limit position A1 plus the stroke angle required for the locking claw mechanism 11 to rotate from the limit position A1 to the first reference position; similarly, the second rotation angle when the locking claw mechanism 11 rotates from the first reference position to the second reference position is a concept of an absolute angle, which refers to the stroke angle required for the locking claw mechanism 11 to directly rotate from the first reference position to the second reference position in the second direction, rather than the stroke angle required for the locking claw mechanism 11 to rotate from the first reference position to the limit position B1 plus the stroke angle required for the locking claw mechanism 11 to rotate from the limit position B1 to the second reference position.

[0092] It can be seen that through steps 122 to 126, the calibration direction of the smart lock 10 can be verified, enabling the calibration method 101 to more correctly and accurately determine the calibrated first automatic locking position or the first automatic unlocking position; and determine the calibrated automatic locking direction and automatic unlocking direction.

[0093] When the first status bit corresponds to the manual unlocking position, considering that there may be different types of door locks 20, it is necessary to determine the automatic unlocking position of the smart lock 10 according to the types of different door locks. Please refer to Figure 12 , after step 124 of the calibration method 101 in some embodiments, the following step 128 is further included:

[0094] Step 128: Determine the second automatic unlocking position.

[0095] In some embodiments, step 128 obtains the third rotation angle at which the lock claw mechanism 11 rotates to the second reference position in the first direction without being forced by the driving mechanism 12, that is, the rotation angle at which the lock claw mechanism 11 rotates from the limit position B1 to the second reference position in the first direction, which is called the third rotation angle; determines whether the third rotation angle is greater than a preset angle threshold. If the third rotation angle is greater than the angle threshold, then the position where the lock claw mechanism 11 rotates from the first reference position to the second direction to its rotation limit position, that is, the limit position B1, is used as the calibrated second automatic unlocking position.

[0096] Among them, the angle threshold is determined according to the rotation angle at which the lock claw mechanism 11 rotates in the first direction due to the structural elastic deformation of the smart lock 10 and / or the door lock 20 without being forced by the driving mechanism 12 when the door lock 20 is of the first type. For example, it can be any one of 1° to 5°.

[0097] Since the oblique tongue 22b of the second type of door lock 20 will automatically rebound to the first pending position, the rotation angle at which the lock claw mechanism 11 rotates in the first direction due to the drive of the operating part 23 of the door lock 20 and the structural elastic deformation of the smart lock 10 and / or the door lock 20 will be much greater than the above angle threshold.

[0098] Understandably, if the third rotation angle is greater than the angle threshold, it indicates that the rotation angle from the limit position B1 to the second reference position in the first direction is relatively large. Therefore, it rotates from the limit position B1 to the second reference position due to the drive of the operating part 23 of the door lock 20 and the elastic deformation of the structure of the intelligent lock 10 and / or the door lock 20. It can be determined that the type of the door lock 20 is the second type. At this time, the limit position B1 needs to be used as the second automatic unlocking position of the intelligent lock 10. The second automatic unlocking position actually corresponds to the position where both the latch 22a and the deadbolt 22b of the door lock 20 are unlocked, that is, the corresponding situation is that both the latch 22a and the deadbolt 22b of the door lock 20 retract into the lock body 21 to achieve unlocking.

[0099] In some embodiments, if the third rotation angle is not greater than the angle threshold, it indicates that the rotation angle from the limit position B1 to the second reference position in the first direction is relatively small. Therefore, it rotates from the limit position B1 to the second reference position not due to the drive of the operating part 23 of the door lock 20, but due to the elastic deformation of the structure of the intelligent lock 10 and / or the door lock 20. It can be determined that the type of the door lock 20 is the first type. Since the door lock 20 of the first type does not have a deadbolt 22b, there is no situation where both the latch 22a and the deadbolt 22b of the door lock 20 retract into the lock body 21 to achieve unlocking, that is, the door lock 20 of the first type does not have a second automatic unlocking position. Therefore, for the door lock 20 of the first type, there is no need to record the second automatic unlocking position.

[0100] In step 128, by judging whether the third rotation angle is greater than the preset angle threshold, the type of the door lock 20 is confirmed, so that different unlocking positions can be confirmed according to the judged type of the door lock 20, making the calibration method 101 adaptable to different door lock designs and compatible with multiple door lock types.

[0101] It can be seen that both step 128 and step 126 need to use the cooperation of step 122 and step 124. However, it should be noted that the calibration method 101 may include step 126 but not step 128, or may include step 128 but not step 126, or may also include both step 126 and step 128, which depends on the calibration function to be designed.

[0102] In addition, as described above, in some embodiments, the first status bit may be the manual unlocking position or the manual locking position of the smart lock 10, that is, the unlocking position or the locking position corresponding to the door lock 20. Considering that under normal circumstances, it is the user's manual operation that causes the locking pawl mechanism 11 to be rotated to the first status bit, after step 110 of the calibration method 101 in response to the calibration instruction, a further step may be included: when the first status bit corresponds to the manual unlocking position, taking the first status bit, that is, the manual unlocking position, as the calibrated first automatic unlocking position; or, when the first status bit corresponds to the manual locking position, taking the first status bit, that is, the manual locking position, as the calibrated first automatic locking position.

[0103] In this embodiment, since the first status bit is the unlocking or locking position manually confirmed by the user, when the first status bit corresponds to the manual unlocking position, taking the manual unlocking position as the calibrated first automatic unlocking position; or, when the first status bit corresponds to the manual locking position, taking the manual locking position as the calibrated first automatic locking position will be more accurate.

[0104] Please refer to Figure 13 , the calibration method 301 of some embodiments includes the following steps:

[0105] Step 310: In response to the calibration instruction, apply a force to the locking pawl mechanism 11 through the driving mechanism 12 to drive the locking pawl mechanism 11 to rotate in the second direction.

[0106] Step 320: Determine the second reference position.

[0107] Specifically, in step 320, after the locking pawl mechanism 11 rotates in the second direction to its rotation limit position, control the driving mechanism 12 to stop applying a force to the locking pawl mechanism 11, so that the locking pawl mechanism 11 rotates in the first direction and stops without being applied a force by the driving mechanism 12, and obtain the stopped position as the second reference position; wherein, the first direction and the second direction are opposite.

[0108] After the locking pawl mechanism 11 rotates in the second direction to its rotation limit position (which may be called the limit position B2), the driving mechanism 12 stops applying a force to the locking pawl mechanism 11. At this time, the locking pawl mechanism 11 will rotate in the first direction and stop at a certain position due to the structural elastic deformation of the smart lock 10 and / or the door lock 20 without being applied a force by the driving mechanism 12. This position is the position expected to be obtained in step 320, that is, the second reference position.

[0109] Step 330: Determine at least the first automatic locking position or the first automatic unlocking position.

[0110] Among them, the first automatic locking position corresponds to the locking position of the locking tongue 22 of the door lock 20 (i.e., the position where the locking tongue 22 extends out of the lock body 21); specifically, if the type of the door lock is the first type of door lock, the first automatic locking position corresponds to the locking position of the locking bolt 22a of the door lock 20 (i.e., the position where the locking bolt 22a extends out of the lock body 21), and if the type of the door lock is the second type of door lock, the first automatic locking position corresponds to the locking positions of the locking bolt 22a and the oblique tongue 22b of the door lock 20 (i.e., the positions where the locking bolt 22a and the oblique tongue 22b extend out of the lock body 21).

[0111] The first automatic unlocking position corresponds to the unlocking position of the locking tongue 22 of the door lock 20 (i.e., the position where the locking tongue 22 retracts into the lock body 21); specifically, if the type of the door lock is the first type of door lock, the first automatic unlocking position corresponds to the unlocking position of the locking bolt 22a of the door lock 20 (i.e., the position where the locking bolt 22a retracts into the lock body 21), and if the type of the door lock is the second type of door lock, the first automatic unlocking position corresponds to the unlocking position of the locking bolt 22a of the door lock 20 (i.e., the position where the locking bolt 22a retracts into the lock body 21).

[0112] For example, in step 330, the second reference position is used as the calibrated first automatic locking position, and step 330 also uses the second direction as the automatic locking direction and the first direction as the automatic unlocking direction. Or, for example, in step 330, the second reference position is used as the calibrated first automatic unlocking position, and step 330 also uses the first direction as the automatic unlocking direction and the second direction as the automatic locking direction.

[0113] Please refer to Figure 14 , the calibration method 301 in some embodiments further includes the following steps:

[0114] After executing step 310 in response to the calibration instruction and before applying a force to the locking pawl mechanism 11 through the driving mechanism 12 to drive the locking pawl mechanism 11 to rotate in the second direction, execute the following steps 302-303:

[0115] Step 302: Apply a force to the locking pawl mechanism through the driving mechanism to drive the locking pawl mechanism to rotate in the first direction.

[0116] In some specific embodiments, step 302 may be to apply a force to the locking pawl mechanism 11 through the driving mechanism 12 to drive the locking pawl mechanism 11 to rotate in the first direction from the first state position when the locking pawl mechanism 11 is in the first state position; where the first state position may be the manual locking position or the manual unlocking position of the intelligent lock 10, that is, the locking position or the unlocking position corresponding to the door lock 20.

[0117] Among them, the manual unlocking position or the manual locking position is the unlocking position or the locking position of the smart lock 10 confirmed by the user manually. For example, the user can be prompted by a terminal such as a smart phone to manually rotate the lock claw mechanism 11 to the unlocking position or the locking position. An operation APP corresponding to the smart lock 10 is installed on the smart phone. The operation APP prompts the user to manually rotate the lock claw mechanism 11 to the unlocking or locking position. If the user confirms that the lock claw mechanism 11 is not currently in the first state position, the user manually rotates the rotating member 14 to rotate the lock claw mechanism 11 to the unlocking or locking position, and then issues a confirmation instruction to the smart lock 10 through the operation APP, so as to apply a force to the lock claw mechanism 11 through the driving mechanism 12 to drive the lock claw mechanism 11 to rotate in the first direction; if the user confirms that the lock claw mechanism 11 is currently in the first state position, the user can directly issue a confirmation instruction to the smart lock 10 through the operation APP, so as to apply a force to the lock claw mechanism 11 through the driving mechanism 12 to drive the lock claw mechanism 11 to rotate in the first direction.

[0118] In this embodiment, applying a force to the lock claw mechanism 11 through the driving mechanism 12 to drive the lock claw mechanism 11 to rotate from the first state position in the first direction can more accurately confirm the automatic unlocking position and the automatic locking position of the smart lock 10.

[0119] Correspondingly, in step 330, when the first state position is the manual locking position of the smart lock 10, that is, corresponding to the manual locking position of the door lock 20, the second reference position is used as the calibrated first automatic unlocking position, the second direction is used as the automatic unlocking direction, and the first direction is used as the automatic locking direction; or, in step 330, when the first state position is the manual unlocking position of the smart lock 10, that is, corresponding to the manual unlocking position of the door lock 20, the second reference position is used as the calibrated first automatic locking position, the second direction is used as the automatic locking direction, and the first direction is used as the automatic unlocking direction.

[0120] Step 303: Determine the first reference position.

[0121] Specifically, after the lock claw mechanism 11 rotates from the first state position in the first direction to its rotation limit position (which may be called the limit position A2), the driving mechanism 12 is controlled to stop applying a force to the lock claw mechanism 11. Thus, the lock claw mechanism 11 rotates in the second direction and stops without being applied a force by the driving mechanism 12, and the stopped position is obtained as the first reference position.

[0122] After step 303, step 310 may be executed to apply force to the pawl mechanism 11 through the driving mechanism 12 to drive the pawl mechanism 11 to rotate in the second direction. Since in step 303, the pawl mechanism 11 rotates in the second direction and stops without being applied force by the driving mechanism 12, and the stopped position is the first reference position, step 310 is then executed to apply force to the pawl mechanism 11 through the driving mechanism 12 to drive the pawl mechanism 11 to rotate from the first reference position to the second direction, and then steps 320 and 330 are executed. Steps 320 and 330 have been described in detail above and will not be repeated here.

[0123] In some embodiments, the calibration method 301 further includes, after step 320, step 322: determining a calibrated first automatic locking position or a first automatic unlocking position based on at least the first reference position and the second reference position.

[0124] In some embodiments, in step 322, it can be determined whether a first angle difference between a first rotation angle when the pawl mechanism 11 rotates from the first state position to the first reference position and a second rotation angle when the pawl mechanism 11 rotates from the first reference position to the second reference position is not greater than a preset angle difference threshold.

[0125] The preset angle difference threshold is set according to manual experience, for example, it can be any one of 0° to 30°.

[0126] It should be noted that the first rotation angle when the pawl mechanism 11 rotates from the first state position to the first reference position is an absolute angle concept, which refers to the travel angle required for the pawl mechanism 11 to rotate directly from the first state position to the first reference position, and does not refer to the travel angle required for the pawl mechanism 11 to rotate from the first state position to the extreme position A2 plus the travel angle of the pawl mechanism 11 from the extreme position A2 to the first reference position; similarly, the second rotation angle when the pawl mechanism 11 rotates from the first reference position to the second reference position is an absolute angle concept, which refers to the travel angle required for the pawl mechanism 11 to rotate directly from the first reference position to the second reference position, and does not refer to the travel angle required for the pawl mechanism 11 to rotate from the first reference position to the extreme position B2 plus the travel angle of the pawl mechanism 11 from the extreme position B2 to the second reference position.

[0127] In some embodiments, a judgment is made in step 322. If the first angular difference is not greater than the angular difference threshold, then in the case where the first status bit corresponds to the manual locking position, step 330 takes the first reference position as the calibrated first automatic unlocking position, and the first direction can be taken as the automatic unlocking direction, and the second direction as the automatic locking direction; or, if the first angular difference is not greater than the angular difference threshold, then in the case where the first status bit corresponds to the manual unlocking position, step 330 takes the first reference position as the calibrated first automatic locking position, and the first direction can be taken as the automatic locking direction, and the second direction as the automatic unlocking direction.

[0128] It should be noted that since the rotation angles of the intelligent lock 10 in the unlocking direction and the locking direction are the same or close, the accuracy of the calibration direction can be judged by the magnitude relationship between the first angular difference between the first rotation angle and the second rotation angle and the angular difference threshold. If the first angular difference is not greater than the angular difference threshold, it can be shown that the calibration direction is correct. In the case where the calibration direction is correct, the first reference position can be taken as the calibrated first automatic unlocking position or the first automatic locking position.

[0129] In some embodiments, a judgment is made in step 322. If the first angular difference is greater than the angular difference threshold, it can be shown that the calibration direction is incorrect. In the case where the calibration direction is incorrect, the driving mechanism 12 applies a force to the locking claw mechanism 11 to drive the locking claw mechanism 11 to rotate from the second reference position in the first direction; after the locking claw mechanism 11 rotates from the second reference position in the first direction to its rotation limit position A3, the driving mechanism 12 is controlled to stop applying a force to the locking claw mechanism 11, so that the locking claw mechanism 11 rotates in the second direction and stops without being applied a force by the driving mechanism 12, and the stopped position is obtained as the third reference position.

[0130] In some examples, in the case where the first status bit corresponds to the manual unlocking position, in some examples, if the door lock 20 is of the first type, the locking claw mechanism 11 will rotate in the second direction due to the structural elastic deformation of the intelligent lock 10 and / or the door lock 20 without being applied a force by the driving mechanism 12. In some examples, if the door lock 20 is of the second type, the locking claw mechanism 11 will rotate in the second direction due to the driving of the operating part 23 of the door lock 20 and the structural elastic deformation of the intelligent lock 10 and / or the door lock 20 without being applied a force by the driving mechanism 12.

[0131] More specifically, when the first status bit corresponds to the manual unlocking position, if the door lock 20 is of the first type, the locking claw mechanism 11 will rotate in the second direction under the action of the structural elastic deformation of the intelligent lock 10 and / or the door lock 20 without being forced by the driving mechanism 12, and finally stop at a certain position after reaching it, and this position is the first reference position. If the door lock 20 is of the second type, as recorded above, its oblique tongue 22b will retract into the lock body 21 of the door lock 20 from the first pending position by a driving method when the door lock 20 is unlocked, and will rebound to the above-mentioned first pending position after the unlocking action is completed; therefore, in step 303, after the locking claw mechanism 11 rotates from the first status bit to the first direction to its limit position A2, the driving mechanism 12 is controlled to stop applying force to the locking claw mechanism 11. At this time, the oblique tongue 22b will automatically rebound to the first pending position, and the operating part 23 on the door lock 20 will be driven to rotate in the second direction during this process, so that the locking claw mechanism 11 rotates in the second direction due to the drive of the operating part 23 of the door lock 20 without being forced by the driving mechanism 12, and the structural elastic deformation of the intelligent lock 10 and / or the door lock 20, and finally stops at a certain position after reaching it, and this position is the third reference position.

[0132] Next, in step 322, the calibrated first automatic locking position or the first automatic unlocking position is determined according to the first reference position, the second reference position, and the third reference position.

[0133] The following describes how to determine the calibrated first automatic locking position or the first automatic unlocking position according to the first reference position, the second reference position, and the third reference position in step 322.

[0134] In step 322, it is judged whether the second angle difference between the second rotation angle when the locking claw mechanism 11 rotates from the first reference position to the second reference position and the fourth rotation angle when the locking claw mechanism 11 rotates from the second reference position to the third reference position is not greater than the angle difference threshold; if the second angle difference is not greater than the angle difference threshold, it can be explained that the calibration direction is correct, then step 330 takes the second reference position as the calibrated first automatic locking position. Further, the first direction can be used as the automatic unlocking direction, and the second direction can be used as the automatic locking direction; or; if the second angle difference is not greater than the preset angle difference threshold, the second reference position is taken as the calibrated first automatic unlocking position, and the second direction is used as the automatic unlocking direction, and the first direction is used as the automatic locking direction. It can be understood that the second rotation angle and the fourth rotation angle here are still concepts of absolute angles, not the accumulation of stroke angles caused by repeated directions, which has been explained many times in this article and will not be elaborated here.

[0135] In some embodiments, if the second angle difference is greater than the angle difference threshold, the control of the smart lock 10 stops calibration and an error is prompted to the user.

[0136] It can be seen that through step 322, the calibration direction of the smart lock 10 can be verified, enabling the calibration method 301 to more correctly and accurately determine the calibrated first automatic locking position or first automatic unlocking position, automatic locking direction, and automatic unlocking direction.

[0137] In the case where the first status bit corresponds to the manual unlocking position, considering that there may be different types of door locks 20, it is necessary to determine the automatic unlocking position of the smart lock 10 according to the type of different door locks. Therefore, after step 322 of the calibration method 301 in some embodiments, there is also a step: determining the second automatic unlocking position.

[0138] Specifically, obtain the fifth rotation angle of the lock claw mechanism 11 rotating to the third reference position in the second direction without being forced by the driving mechanism 12, that is, the rotation angle of the lock claw mechanism 11 rotating from the limit position A2 to the third reference position in the second direction, which is called the fifth rotation angle; determine whether the fifth rotation angle is greater than a preset angle threshold. If the fifth rotation angle is greater than the angle threshold, then the position where the lock claw mechanism 11 rotates from the second reference position to its rotation limit position, that is, the limit position A2, in the first direction is used as the calibrated second automatic unlocking position.

[0139] Among them, the angle threshold is determined according to the rotation angle at which the lock claw mechanism 11 rotates in the second direction due to the structural elastic deformation of the smart lock 10 and / or the door lock 20 without being forced by the driving mechanism 12 when the door lock 20 is of the first type. For example, it can be any one of 1° to 5°.

[0140] Since the oblique tongue 22b of the door lock 20 of the second type will automatically rebound to the first pending position, the rotation angle of the lock claw mechanism 11 rotating in the second direction due to the drive of the operation part 23 of the door lock 20 and the structural elastic deformation of the smart lock 10 and / or the door lock 20 will be much greater than the above angle threshold.

[0141] Understandably, if the fifth rotation angle is greater than the angle threshold, it indicates that the rotation angle from the limit position A2 to the third reference position in the second direction is relatively large. Therefore, it rotates from the limit position A2 to the third reference position in the second direction due to the drive of the operating portion 23 of the door lock 20 and the structural elastic deformation of the intelligent lock 10 and / or the door lock 20. It can be determined that the type of the door lock 20 is the second type. At this time, the limit position A2 needs to be used as the second automatic unlocking position of the intelligent lock 10. This second automatic unlocking position actually corresponds to the position where both the latch 22a and the deadbolt 22b of the door lock 20 are unlocked, that is, the corresponding situation is that both the latch 22a and the deadbolt 22b of the door lock 20 retract into the lock body 21 to achieve unlocking.

[0142] In some embodiments, if the fifth rotation angle is not greater than the angle threshold, it indicates that the rotation angle from the limit position A2 to the third reference position in the second direction is relatively small. Therefore, it rotates from the limit position A2 to the third reference position in the second direction not due to the drive of the operating portion 23 of the door lock 20, but due to the structural elastic deformation of the intelligent lock 10 and / or the door lock 20. It can be determined that the type of the door lock 20 is the first type. Since the door lock 20 of the first type does not have a deadbolt 22b, there is no situation where both the latch 22a and the deadbolt 22b of the door lock 20 retract into the lock body 21 to achieve unlocking, that is, the door lock 20 of the first type does not have a second automatic unlocking position. Therefore, for the door lock 20 of the first type, there is no need to record the second automatic unlocking position.

[0143] In addition, as described above, in some embodiments, the first state bit can be the manual locking position or the manual unlocking position of the intelligent lock 10, that is, the locking position or the unlocking position corresponding to the door lock 20. Considering that it is usually the user who manually operates to rotate the locking claw mechanism 11 to the first state bit, after step 310 of the calibration method 301 in response to the calibration instruction, there can also be a step: when the first state bit corresponds to the manual locking position, use the first state bit, that is, the manual locking position, as the calibrated first automatic locking position; or, when the first state bit corresponds to the manual unlocking position, use the first state bit, that is, the manual unlocking position, as the calibrated first automatic unlocking position.

[0144] In this embodiment, since the first state bit is that the user manually rotates the rotating member 14 to rotate the locking claw mechanism 11 to the unlocking or locking position, when the first state bit corresponds to the manual unlocking position, using the manual unlocking position as the calibrated first automatic unlocking position; or, when the first state bit corresponds to the manual locking position, using the manual locking position as the calibrated first automatic locking position will be more accurate.
