The present invention relates to a lock device, a bolt calibration method, and a door calibration method, and more particular, to a lock device with sensing function, and a bolt calibration method and a door calibration method initializing the lock device to be adapted to a door.
In general, the electronic locking system uses two micro-switches and a light blocker signal to determine whether to drive a bolt to rotate or not, which further drives a lock core to perform a bolt locking action. For example, the two micro-switches may be disposed at two positions on a rotation path of the bolt, such as a locking position and an unlocking position. When the bolt is rotated to the micro-switch at the locking position, the micro-switch at the locking position is triggered by the bolt to send a locking position signal. When the bolt is rotated to the micro-switch at the unlocking position, the micro-switch at the unlocking position is triggered by the bolt to send an unlocking position signal. In this way, the electronic locking system can recognize a position of the bolt. In addition, a light blocker is located on a door or a wall, and when the door is opened, the door is relatively moving away from the wall. Therefore, the light blocker changes from a blocked state to a non-blocked state. In this way, the electronic locking system is able to recognize the position of the door.
However, the above mechanism requires two micro-switches and one light blocker to determine the position of the bolt and whether or not the door is closed, which requires more components, and causes more cost and process management problems in manufacture.
The present invention provides a lock device with sensing function, and a bolt calibration method and a door calibration method initializing the lock device to be adapted to a door to solve the above mentioned problems.

Specifically, the bolt mechanism 2 includes a transmission member 20, a deadbolt mechanism 21, and the knob member 22. The transmission member 20 is rotatably disposed on the housing 1, the deadbolt mechanism 21 includes a base 210 and a bolt member 211, the base 210 is connected to the transmission member 20, the bolt member 211 is movably disposed on the base 210, and the knob member 22 is connected to one end of the transmission member 20. The lock device 1000 further includes a shell C and a lock core mechanism D. The shell C is disposed on another side of the door 2000 opposite to the housing 1, and the shell C and the housing 1 may be, for example, arranged on an outer side 51 and an inner side S2 of the door 2000, respectively. For example, the inner side S2 of the door 2000 refers to a side located in a house (private space), while the outer side 51 of the door 2000 refers to another side located outside the house (public space).
The lock core mechanism D is disposed on the shell C and connected to one end of the transmission member 20. In practice, the lock core mechanism D may include a lock shell, a sleeve, an upper locking bead set, and a lower locking bead set. The sleeve is disposed inside the lock shell, the upper locking bead set is disposed inside the lock shell, the lower locking bead set is disposed inside the sleeve and against the upper locking bead set, and each lower locking bead of the lower locking bead set is at a different height position. When each lower locking bead of the lower locking bead set is abutted against the corresponding upper locking bead of the upper locking bead set, the lower locking beads of the lower locking bead set are at different height positions. When each lower locking bead of the lower locking bead set abuts against the corresponding upper locking bead of the upper locking bead set and a key E is not inserted into a keyhole on the sleeve, the upper locking beads of the upper locking bead set are held at different heights by the corresponding lower locking beads of the lower locking bead set, respectively. When the upper locking beads of the upper locking bead set are at different heights, one end of each of the upper locking beads of the upper locking bead set is located in the sleeve and another end of each of the upper locking beads of the upper locking bead set is located in the lock shell. In this way, each upper locking bead of the upper locking bead set locks the sleeve so that the sleeve cannot rotate relative to the lock shell. When the key E is inserted into the key hole on the sleeve, each locking tooth of the key E pushes against the corresponding lower locking bead of the lower locking bead set to drive each upper locking bead of the upper locking bead set, so that an end of each upper locking bead of the upper locking bead set moves to a junction of the lock shell and the sleeve. In this way, each upper locking bead of the upper locking bead set can be released from the sleeve, so that the sleeve can rotate relative to the lock shell.
Therefore, the lock core mechanism D can be operated to rotate after being unlocked by the key E. The lock core mechanism D is connected to the end of the transmission member 20, and when the lock core mechanism D is operated to rotate after being unlocked by the key E, the lock core mechanism D can drive the transmission member 20 to rotate. In addition, one end of the transmission member 20 is connected to the knob member 22, so that when the knob member 22 is operated (e.g., rotated) by a user, the knob member 22 can drive the transmission member 20 to rotate. In addition, the transmission member 20 is connected to the base 210 of the deadbolt mechanism 21 through the base 210, and when the transmission member 20 is driven to rotate, the transmission member 20 can drive the bolt member 211 of the deadbolt mechanism 21 to move between the locking position P1 (as shown in the
Furthermore, the magnetic member 3 is movable with the bolt mechanism 2, and the magnetic sensing module 4 is disposed inside the housing 1 and configured to sense magnetic force generated by the magnetic member 3. The lock device 1000 can further include a processing unit 5. In this embodiment, the magnetic sensing module 4 can be a three-axis magnetic sensor, and the processing unit 5 can be a circuit board. The magnetic sensing module 4 is disposed on the circuit board and coupled to the processing unit 5. The magnetic sensing module 4 can further include a magnetic sensing processing unit 40.
The magnetic member 3 is disposed on the lock device 1000 and located on the door 2000. In this embodiment, the magnetic member 3 is affixed on a drive lever of the knob member 22 and moves with the bolt mechanism 2, but the invention is not limited thereto. For example, the magnetic member 3 can also be disposed on the transmission member 20 or the bolt member 211 of the bolt mechanism 2 and movable with the bolt mechanism 2. When the bolt mechanism 2 moves to the unlocking position P2 as shown in
Therefore, during a movement of the bolt mechanism 2 between the locking position P1 and the unlocking position P2, the magnetic member 3 is driven by the bolt mechanism 2 to move away from or close to the magnetic sensing module 4, so that the magnetic sensing module 4 can sense a magnetic force variation generated by the magnetic member 3 relative to the magnetic sensing module 4 during a process of moving away from or close to the magnetic sensing module 4 as a mechanism to determine the position of the bolt mechanism 2.

In this embodiment, the input module 7 can be a set of physical buttons, and the password is in a specific sequence of operating (e.g., pressing) the physical buttons. The bolt calibration method includes the following steps:
Step S100: entering the bolt calibration mode of the lock device 1000;
Step S101: rotating the bolt mechanism 2 of the lock device 1000 at least once between the locking position P1 and the unlocking position P2 after entering the bolt calibration mode of the lock device 1000; and
Step S102: completing a calibration of the lock device 1000.
The lock device 1000 has a mode button G. As shown in
After entering the bolt calibration mode of the lock device 1000, the bolt mechanism 2 of the lock device 1000 is moved at least once between the locking position P1 and the unlocking position P2 (step S101). As described above, when the bolt mechanism 2 is moved to the locking position P1, the magnetic member 3 is most distant from the magnetic sensing module 4, and the magnetic force of the magnetic member 3 is then sensed by the magnetic sensing module 4 as a first magnetic force value T1; when the bolt mechanism 2 is moved to the unlocking position P2, the magnetic member 3 is closest to the magnetic sensing module 4, and the magnetic force of the magnetic member 3 is then sensed by the magnetic sensing module 4 as a second magnetic force value T2.
For example, the bolt mechanism 2 of the lock device 1000 is moved between the locking position P1 and the unlocking position P2 for N times, wherein N is a positive integer, and N first magnetic values (T1, i) and N second magnetic values (T2, i) are generated during a period, wherein i is a positive integer from 1 to N. In this way, the N first magnetic values (T1, i) can be used to derive a first magnetic interruption threshold interval Tr1 for determining whether the bolt mechanism 2 is in the locking position P1, and the N second magnetic values (T2, i) can be used to derive a second magnetic interruption threshold interval Tr2 for determining whether the bolt mechanism 2 is in the unlocking position P2.
For example, when N first magnetic values (T1, i) and N second magnetic values (T2, i) are generated, the N first magnetic values (T1, i) and the first magnetic interruption threshold interval Tr1 can be exemplified as satisfying the relationship of Equation 1, and the N second magnetic values (T2, i) and the second magnetic interruption threshold interval Tr2 can be exemplified as satisfying the relationship of Equation 2:
Min(T1,i)≤Tr1≤Max(T1,i),i=1˜N (Equation 1)
Min(T2,i)≤Tr2≤Max(T2,i),i=1˜N (Equation 2)
In other words, the first magnetic interruption threshold interval Tr1 can be between the maximum of the N first magnetic values (T1, i) and the minimum of the N first magnetic values (T1, i), and the second magnetic interruption threshold interval Tr2 can be between the maximum of the N second magnetic values (T2, i) and the minimum of the N second magnetic values (T2, i). It is worth mentioning that Equation 1 is an example of the present invention, and the relationship between the N first magnetic force values (T1, i) and the first magnetic interruption threshold interval Tr1 can be defined according to actual requirements. Similarly, Equation 2 is an example of the present invention, the relationship between the N second magnetic force values (T2, i) and the second magnetic interruption threshold interval Tr2 can be defined according to actual requirements.
In this way, the processing unit 5 can calculate the first magnetic interrupt valve interval Tr1 and the second magnetic interrupt valve interval Tr2 during the movement of the bolt mechanism 2 between the locking position P1 and the unlocking position P2. Further, the processing unit 5 can store the first magnetic interrupt valve interval Tr1 as a preset locking interval value and store the second magnetic interrupt valve interval Tr2 as a preset unlocking interval value, so as to complete the calibration of the lock device 1000 with respect to the bolt mechanism 2 (step S102). As shown in
Therefore, when a magnitude of the magnetic force sensed by the magnetic sensing module 4 is within the preset locking interval value (i.e., the first magnetic interruption threshold interval Tr1), it can be determined that the lock device 1000 is in the locking position P1; when the magnitude of the magnetic force sensed by the magnetic sensing module 4 is within the preset unlocking interval value (i.e., the second magnetic interruption threshold interval Tr2), it can be determined that the lock device 1000 is in the unlocking position P2.
In this embodiment, the magnetic sensing module 4 can include the magnetic sensing processing unit 40 (as shown in
The following is an example of the processing unit 5 determining whether the magnetic force sensed by the magnetic sensing module 4 is within the preset locking interval value or within the preset unlocking interval value. When the processing unit 5 receives the magnetic force from the magnetic sensing module 4 within the preset locking interval value (i.e., the first magnetic interrupt valve value interval Tr1) or within the preset unlocking interval value (i.e., the second magnetic interrupt valve value interval Tr2), the processing unit 5 generates a magnetic event interrupt signal to indicate that the lock device 1000 is in the locking position P1 or the unlocking position P2. Furthermore, after completing the bolt calibration method, when the user operates the bolt mechanism 2 through the key E or other manners, a magnetic force is generated as a determination of a position of the bolt member 211, and the technical means of the magnetic event interrupt signal being generated when the magnitude of the magnetic force being within the preset locking interval value (i.e., the first magnetic interruption threshold interval Tr1) or within the preset unlocking interval value (i.e., the second magnetic interruption threshold interval Tr2) is a preferred embodiment to achieve power saving, but the present invention is not limited thereto. For example, in other embodiments, determining whether the magnetic event interrupt signal is generated or not can also be set that when the magnetic force received by the processing unit 5 is not within the preset locking interval value or not within the preset unlocking interval value, a magnetic event interrupt signal (corresponding to a redefined equation) can be generated for the lock device 1000 to perform an action.
In this embodiment, the processing unit 5 can be used to generate the magnetic event interrupt signal, but the present invention is not limited thereto. For example, the magnetic sensing processing unit 40 of the magnetic sensing module 4 can also be used to generate the magnetic event interrupt signal, according to actual requirements.
In this embodiment, the lock device 1000 can further include a warning module 6 coupled to the processing unit 5, and the warning module 6 can be a buzzer. When the magnetic force received by the processing unit 5 from the magnetic sensing module 4 is not within the preset locking interval value (i.e., the first magnetic interruption threshold interval Tr1) and not within the preset unlocking interval value (i.e., the second magnetic interruption threshold interval Tr2), in one embodiment, the processing unit 5 controls the warning module 6 (i.e., the buzzer) to generate a warning signal (e.g., a warning tone). In another embodiment, the magnetic sensing processing unit 40 of the magnetic sensing module 4 controls the warning module 6 (i.e., the buzzer) to generate a warning signal (e.g., a warning tone), so as to notify the user that the lock device 1000 is not in the locking position P1 nor in the unlocking position P2. That is to say, the lock device 1000 can generate the warning signal (e.g., the warning tone) to notify the user to make a check of whether a bolt is bolted or not, and the processing unit 5 can also control the lock device 1000 to enter a sleep mode to save power consumption of a battery.

The lock device 1000 can further include a magnetic force generating member B, which is disposed on the wall. The door calibration method includes the following steps:
Step S200: entering a door calibration mode of the lock device 1000;
Step S201: moving the door 2000 to a door-closed position, disposing the bolt mechanism 2 at the locking position P1, and shaking the door 2000 at least once relative to the wall after entering the door calibration mode of the lock device 1000; and
Step S202: completing a calibration of the door 2000.
When it is desired to enter the door calibration mode of the lock device 1000, the mode button G can be pressed firstly to enter a setting mode. After entering the setting mode, the “key number 1” and “key number 9” of the set of physical buttons are pressed to enter the door calibration mode of the lock device 1000 (step S200). In other words, a sequence of pressing “key number 1” and “key number 9” can be the specific sequence for entering the door calibration mode of this embodiment, but the invention is not limited thereto. The specific sequence can also be an arrangement of the key numbers on the group of physical buttons, according to actual requirements. In addition, in step S200, when it is desired to enter the door calibration mode of the lock device 1000, the communication between the electronic device 9 and the lock device 1000 also can be established, such as establishing a communication between the lock device 1000 and the electronic device 9 through the user interface of the application A installed in the electronic device 9 (e.g., by clicking on a button icon of the user interface of the application A) to enter the door calibration mode. In addition, when the door calibration mode is completed, the user interface can display a status column corresponding to a position of the door. For example, the status column of the opening door is “open” and the status column of the closed door is “closed”, and a displacement value of the door 2000 can also be displayed. For the sake of brevity, detailed figures and descriptions are omitted.
After entering the calibration mode of the lock device 1000, the door 2000 is moved to the door-closed position and the bolt mechanism 2 is disposed at the locking position P1, and then the door 2000 is shaken relative to the wall at least once (step S201). During the process of shaking the door 2000 relative to the wall, the magnetic sensing module 4 moves close to and away from a magnetic force generating member B located on the wall with the door 2000. Therefore, the magnetic sensing module 4 can sense at least one magnetic force variation generated by the magnetic force generating member B during a shaking process of the door 2000 relative to the wall, and the processing unit 5 can determine a door threshold interval X according to the at least one magnetic force variation and a range of the magnetic force variation sensed by the magnetic sensing module 4 when the door is in the door-closed position.
For example, take that the door is in the door-closed position 2000 and the bolt mechanism 2 is in the locking position P1, and the door is shaken for M times as an example, wherein M is a positive integer, and M magnetic values (W, j) are generated during a period, wherein j is a positive integer from 1 to M. In this way, M magnetic values are generated. In this way, the M magnetic values (W, j) can be used to derive the door threshold interval X for determining whether the door 2000 is in the door-closed position.
For example, after generating M magnetic values (W, j), the M magnetic values (W, j) and the door threshold interval X can be exemplified as satisfying the relationship in Equation 3:
Min(W,j)≤X≤Max(W,j),j=1˜M (Equation 3)
In other words, the door threshold interval X can be between the maximum of the M magnetic values (W, j) and the minimum of the M magnetic values (W, j). It is worth mentioning that, Equation 3 is an example of the present invention, the relationship between the M magnetic force values (W, j) and the door threshold interval X can be defined according to actual requirements.
In this way, the processing unit 5 can calculate the door threshold interval X during the process of the door 2000 close to and away from the door-closed position. Furthermore, the processing unit 5 can store the door threshold interval X as a preset door interval value to complete the calibration of the lock device 1000 to the door 2000 (step S202). As shown in
In practice, when the processing unit 5 or the magnetic sensing processing unit 40 receives the magnetic force from the magnetic sensing module 4 within the preset door interval value (i.e., the door threshold interval X), the processing unit 5 determines that the door 2000 is in the door-closed position. When the processing unit 5 or the magnetic sensing processing unit 40 receives the magnetic force from the magnetic sensing module 4 not within the preset door interval value (i.e., the door threshold interval X), the processing unit 5 determines that the door 2000 is in an abnormal state and further generates a door unclosed warning signal. For example, when the magnetic force from the magnetic sensing module 4 is not within the preset door interval value (i.e., the door threshold interval X), the door unclosed warning signal can be generated by the processing unit 5 to control the warning module 6 (i.e., the buzzer) to generate the warning signal (e.g., the warning tone) to notify the user that the door 2000 is not at the door-closed position, i.e., the lock device 1000 can generate the warning signal (e.g., the warning tone) to notify the user of making a check of whether the door 2000 is closed or not.
Compared with the prior art, the lock device of the present invention include a housing, a bolt mechanism, a magnetic member, and a magnetic sensing module. The magnetic member is movable with the bolt mechanism, and the magnetic sensing module senses the magnetic force generated by the magnetic member during the movement of the bolt mechanism between the locking position and the unlocking position. The lock device of the present invention further includes a magnetic force generating member, and the magnetic force generating member is disposed on the wall. The magnetic sensing module senses the magnetic force variation generated by the magnetic force generating member during the process of moving the bolt mechanism to the locking position and shaking the door relative to the wall when the door is moved to the door-closed position. In this way, the lock device of the invention requires only a single magnetic sensing module to sense the magnetic force generated by the magnetic member moving with the bolt mechanism to determine the position of the bolt, and to sense the magnetic generating member disposed on the wall to determine the position of the door.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
