Description

Technical Field

[0001] The present invention relates to a smart lock, more specifically to a smart lock capable of automatically determining a door opening direction and a smart lock setting method. Background Art

[0002] A fully automatic smart lock usually includes a lock body, a drive motor disposed on the lock body, a door opening button disposed on the lock body, a control module connected to the drive motor and controlling the rotation of the drive motor, and a lock tongue connected to the drive motor and extending relative to the lock body under the drive of the drive motor. The door opening button is electrically connected to the drive motor and after the door opening button is pressed, the drive motor drives the lock tongue to rotate. Since the smart lock usually presets the rotation direction of the drive motor in the control module, it can adapt to opening the door from a certain direction, such as opening the door from the left, rotating clockwise when opening the door, and counterclockwise when closing the door. When opening the door, press the door opening button, and the control module controls the drive motor to drive the lock tongue to rotate clockwise to open the door. However, since the door opening direction may be the left side or the right side, and since the rotation direction of the drive motor has been pre-set, only one door opening method can be adapted. For example, if the preset door opening is on the left, the door rotates clockwise when opening and counterclockwise when closing, then if the door is installed on the right, then at this time, when opening the door, the drive motor still rotates clockwise as preset, then the door opening becomes the door closing, and the door closing becomes the door opening, which is completely opposite. Therefore, in order to adapt to different door opening directions, the door opening direction needs to be adjusted during installation.

[0003] The Chinese patent with publication number CN107762287A discloses an intelligent lock drive device adapted to door panels with different door opening directions, which is provided with a rotating drive component, a main control module and a setting module, and uses the setting module to provide setting information adapted to the door opening direction entered by the user, and the main control module is electrically connected to the setting module, and the main control module controls the forward or reverse rotation of the rotating drive component according to the setting information so that the forward or reverse operation matches the unlocking or locking operation under different door opening directions, thereby quickly adjusting the door opening direction. However, the existing adjustment needs to be made by manual setting, which is very inconvenient to use and adjust. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention is described in detail below with reference to the embodiments and accompanying drawings, wherein:

[0030] Figure 1 It is a schematic diagram of the structure of the smart lock for automatically determining the door opening direction of the present invention installed on the door;

[0031] Figure 2 It is a principle diagram of the intelligent lock for automatically determining the door opening direction of the present invention. DETAILED DESCRIPTION

[0032] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings:

[0033] Please also see Figure 1 to Figure 2 The intelligent lock for automatically determining the door opening direction of the present invention comprises a lock body 1, a drive motor 2, a control module 3, a lock tongue 4, a door opening and closing detection module 5 and a stall current detection module 6. Among them:

[0034] The lock body 1 is installed on the door 10. In this specific embodiment, the smart lock is a fully automatic smart lock.

[0035] The drive motor 2 is arranged on the lock body. The drive motor is mainly used to drive the lock tongue to telescopic movement, thereby realizing opening and closing the door.

[0036] The control module 3 is connected to the drive motor and controls the rotation of the drive motor. When the smart lock leaves the factory, the rotation direction of the drive motor is preset in the control module, that is, the door opening direction and the door closing direction are preset, so as to correspond to the left door opening direction or the right door opening direction. For example, the rotation direction of the drive motor preset in the control module corresponds to the left door opening, the preset door opening direction is clockwise, and the preset door closing direction is counterclockwise. When closing the door, the control module controls the drive motor to rotate counterclockwise, thereby driving the lock tongue to rotate counterclockwise. When opening the door, the control module controls the drive motor to rotate clockwise, thereby driving the lock tongue to rotate clockwise.

[0037] Therefore, if the factory setting direction of the smart lock is inconsistent with the actual door opening direction, an error will occur. For example, if the preset door opening is on the left, the door rotates clockwise when opening and counterclockwise when closing, then if the door is opened on the right during installation, then at this time, when opening the door, the drive motor still rotates clockwise according to the preset, then opening the door becomes closing the door, and closing the door becomes opening the door, which is completely opposite. Therefore, in order to adapt to different door opening directions, the door opening direction needs to be adjusted during installation.

[0038] The lock tongue 4 is arranged on the lock body, connected to the driving motor and can be extended and retracted relative to the lock body under the driving of the driving motor. The lock tongue is used to cooperate with the slot on the door frame to close the door.

[0039] The door opening and closing detection module 5 is connected to the control module and detects whether the smart lock is in an open door state or a closed door state, and sends a door opening signal to the control module when it is detected that the smart lock is in an open door state, and the control module controls the drive motor to drive the lock tongue to rotate in a preset open door direction; sends a door closing signal to the control module when it is detected that the smart lock is in a closed door state, and the control module controls the drive motor to drive the lock tongue to rotate in a preset closed door direction.

[0040] The door opening and closing detection module is mainly used to detect the status of the smart lock and the door, so that the smart lock can know whether it is currently in the open or closed state. The door opening and closing detection module can be implemented by a mechanical structure, and can also be implemented by a photoelectric sensor. In this specific embodiment, the door opening and closing detection module is implemented by a mechanical structure. The door opening and closing detection module 5 includes a retractable detection tongue 51 provided on the lock body and a detection switch (not shown in the figure) connected to the detection tongue. After the detection tongue is pressed, the detection switch sends the door closing signal to the control module. After the detection tongue pops up, the detection switch sends the door opening signal to the control module. The detection switch can be implemented by an ordinary push-type mechanical switch. The detection tongue has an elastic reset structure, which is installed on the lock body and can be automatically reset by a spring. When the door is closed or the detection tongue is pressed manually, the detection tongue is pressed into the lock body, the detection switch is pressed, and a door closing signal is sent to the control module. The control module controls the drive motor to drive the lock tongue to rotate in the preset door closing direction. When the door is opened or is not considered to be pressed, the detection tongue automatically resets under the action of the spring and extends out of the lock body. The detection switch is not pressed, and a door opening signal is sent to the control module. The control module controls the drive motor to drive the lock tongue to rotate in the preset door closing direction.

[0041] The stall current detection module 6 is connected to the door opening and closing detection module and the control module, and detects the current of the drive motor after the door opening and closing detection module sends the door closing signal, and determines whether the drive motor is stalled according to the current of the drive motor, and sends a reverse configuration signal to the control module when the drive motor is stalled. The stall current detection module is mainly used to detect whether the drive motor is stalled. When the door opening direction is inconsistent with the preset direction of the control module, the lock tongue can no longer be retracted into the lock body, so that the drive motor is stalled, and the current of the drive motor will increase sharply, that is, a stall current will be generated. At this time, the stall current is detected by the stall current detection module, and it can be determined that the door opening direction is opposite to the preset direction of the control module, and the stall current detection module sends a reverse configuration signal to the control module.

[0042] The control module reversely sets the preset door opening direction and the preset door closing direction according to the reverse configuration signal and saves the reverse setting. For example, the control module originally presets the door opening direction to open on the left, the preset door opening direction to rotate clockwise, and the preset door closing direction to rotate counterclockwise, and the door is opened on the right during installation. Since the drive motor is blocked, after receiving the reverse configuration signal, the original preset door opening direction is reset to rotate counterclockwise, and the preset door closing direction is reset to rotate clockwise, so that the door opening direction can be automatically adjusted to open on the right, the door opening direction can be automatically determined, and the door opening direction can be automatically adjusted, and the door opening direction does not need to be manually adjusted, and the adjustment is very convenient.

[0043] When no stall of the drive motor is detected, the control module does not adjust the preset door opening direction and the preset door closing direction.

[0044] The present invention detects whether the smart lock is in an open door state or a closed door state through a door opening and closing detection module, and sends a door closing signal to a control module when the smart lock is detected to be in a closed door state, and the control module controls the drive motor to drive the lock tongue to rotate in a preset door closing direction; then the stall current detection module detects the current of the drive motor, and determines whether the drive motor is stalled according to the current of the drive motor, and sends a reverse configuration signal to the control module when the drive motor is stalled; the control module reversely sets the preset door opening direction and the preset door closing direction according to the reverse configuration signal and saves the reverse setting. Therefore, in actual use, it is only necessary to install the smart lock on the door, and then close the door, the door opening and closing detection module sends a door closing signal, and the control module controls the drive motor to drive the lock tongue to rotate in a preset door closing direction. When the installation direction of the smart lock is consistent with the preset direction, the drive motor will not stall; when the installation direction of the smart lock is inconsistent with the preset direction, due to the limitation of the mechanical parts of the lock body, the lock tongue cannot continue to retract inward, and the drive motor stalls. The stall current detection module sends a reverse configuration signal after detecting the stall, and the control module reversely sets the preset door opening direction and the preset door closing direction according to the reverse configuration signal and saves the reverse setting, so that there is no need to manually set the door opening direction, and it is more convenient to use and adjust.

[0045] Since the door opening direction only needs to be adjusted during the initial installation, in order to avoid the subsequent blocking and causing the wrong reversal due to other reasons, the smart lock that automatically determines the door opening direction also includes a direction setting module 7. The direction setting module 7 is provided with a direction setting button. After pressing the direction setting button, the direction setting state is entered; the blocking current electric measurement module only determines whether the drive motor is blocked and sends the reverse configuration signal in the direction setting state; after saving the reverse setting, it also includes exiting the direction setting state. Therefore, the direction setting state can be entered only after the initial installation, and the direction setting can be exited after the setting is completed. If the control module does not receive the reverse configuration signal, the original preset direction will not be adjusted, and then the direction setting state will be exited in the same way. The direction setting module is connected to the blocking current detection module and the control module.

[0046] In this specific embodiment, determining whether the drive motor is stalled includes:

[0047] Determine whether the current of the drive motor exceeds the preset value and lasts for a preset time. When the current of the drive motor exceeds the preset value and lasts for a preset time, determine that the drive motor is stalled, thereby avoiding erroneous settings caused by current fluctuations of the drive motor.

[0048] In this specific embodiment, the smart lock that automatically determines the direction of door opening also includes a voice prompt module 8 connected to the direction setting module and the control module. After pressing the direction setting button, the voice prompt module issues a prompt for entering the direction setting state, and the control module sends a reverse configuration prompt signal to the voice prompt module according to the reverse configuration signal, and the voice prompt module issues a start reverse configuration prompt according to the reverse configuration prompt signal; after saving the reverse setting, the control module sends a reverse configuration success prompt signal to the voice prompt module, and the voice prompt module sends a reverse configuration success prompt according to the reverse configuration success prompt signal, so that the user can clearly know the entire adjustment process through voice prompts.

[0049] The smart lock setting method of the present invention includes:

[0050] Step 1: Install the smart lock on the door so that the door opening and closing detection module detects that the smart lock is in the closed state.

[0051] Step 2: The door opening and closing detection module sends a door closing signal, and the control module controls the drive motor to drive the lock tongue to rotate in the preset door closing direction.

[0052] The door opening and closing detection module is mainly used to detect the status of the smart lock and the door, so that the smart lock can know whether it is currently in the open or closed state. The door opening and closing detection module can be implemented by a mechanical structure, and can also be implemented by a photoelectric sensor. In this specific embodiment, the door opening and closing detection module is implemented by a mechanical structure. The door opening and closing detection module 5 includes a retractable detection tongue 51 provided on the lock body and a detection switch (not shown in the figure) connected to the detection tongue. After the detection tongue is pressed, the detection switch sends the door closing signal to the control module. After the detection tongue pops up, the detection switch sends the door opening signal to the control module. The detection switch can be implemented by an ordinary push-type mechanical switch. The detection tongue has an elastic reset structure, which is installed on the lock body and can be automatically reset by a spring. When the door is closed or the detection tongue is pressed manually, the detection tongue is pressed into the lock body, the detection switch is pressed, and a door closing signal is sent to the control module. The control module controls the drive motor to drive the lock tongue to rotate in the preset door closing direction. When the door is opened or is not considered to be pressed, the detection tongue automatically resets under the action of the spring and extends out of the lock body. The detection switch is not pressed, and a door opening signal is sent to the control module. The control module controls the drive motor to drive the lock tongue to rotate in the preset door closing direction.

[0053] When it is implemented by a photoelectric sensor, it can be implemented by setting an infrared light transmitter and an infrared light receiver. The light emitted by the infrared light transmitter is blocked by the door frame, and the reflected light is received by the infrared light receiver, which is judged as a closed door state. If the infrared light receiver does not receive the reflected light, it is judged as an open door state.

[0054] Step 3: The stall current detection module detects the current of the drive motor, and determines whether the drive motor is stalled according to the current of the drive motor, and sends a reverse configuration signal to the control module when the drive motor is stalled.

[0055] The stall current detection module is mainly used to detect whether the drive motor is stalled. When the door opening direction is inconsistent with the preset direction of the control module, the lock tongue can no longer be retracted into the lock body, causing the drive motor to be stalled. The current of the drive motor will increase sharply, and a stall current will be generated. At this time, the stall current detection module detects the stall current, and it can be determined that the door opening direction is opposite to the preset direction of the control module. The stall current detection module sends a reverse configuration signal to the control module.

[0056] Step 4: The control module reverses the preset door opening direction and the preset door closing direction according to the reverse configuration signal and saves the reverse setting.

[0057] For example, the control module's original preset door opening direction is left-side door opening, the preset door opening direction is clockwise, and the preset door closing direction is counterclockwise. When installed, the door is opened to the right. Since the drive motor is stuck, after receiving the reverse configuration signal, the original preset door opening direction is reset to counterclockwise, and the preset door closing direction is reset to clockwise. The door opening direction can be automatically adjusted to right-side door opening, the door opening direction can be automatically determined, and the door opening direction can be automatically adjusted. There is no need to manually adjust the door opening direction, and the adjustment is very convenient.

[0058] When no stall of the drive motor is detected, the control module does not adjust the preset door opening direction and the preset door closing direction.

[0059] Since the door opening direction only needs to be adjusted during initial installation, in order to avoid subsequent blocking due to other reasons and causing accidental reversal, the smart lock setting method also includes:

[0060] Before the door opening and closing monitoring module detects that the smart lock is in the closed state, the direction setting button is pressed to enter the direction setting state; the stall current electric measurement module determines whether the drive motor is stalled and sends the reverse configuration signal only in the direction setting state;

[0061] After saving the reverse setting, the method further includes exiting the direction setting state.

[0062] Thus, the direction setting state can be entered only after the initial installation, and the direction setting can be exited after the setting is completed. If the control module does not receive the reverse configuration signal, the original preset direction is not adjusted, and then the direction setting state is also exited.

[0063] In this specific embodiment, determining whether the drive motor is stalled includes:

[0064] Determine whether the current of the drive motor exceeds the preset value and lasts for a preset time. When the current of the drive motor exceeds the preset value and lasts for a preset time, determine that the drive motor is stalled, thereby avoiding erroneous settings caused by current fluctuations of the drive motor.

[0065] 10. The smart lock setting method according to claim 7 is characterized in that: the smart lock that automatically determines the door opening direction also includes a voice prompt module connected to the direction setting module and the control module, after pressing the direction setting button, the voice prompt module issues a prompt for entering the direction setting state, the control module sends a reverse configuration prompt signal to the voice prompt module according to the reverse configuration signal, and the voice prompt module sends a start reverse configuration prompt according to the reverse configuration prompt signal; after saving the reverse setting, the control module sends a reverse configuration success prompt signal to the voice prompt module, and the voice prompt module sends a reverse configuration success prompt according to the reverse configuration success prompt signal, so that the user can clearly know the entire adjustment process through voice prompts.

[0066] The present invention detects whether the smart lock is in an open door state or a closed door state through a door opening and closing detection module, and sends a door closing signal to a control module when the smart lock is detected to be in a closed door state, and the control module controls the drive motor to drive the lock tongue to rotate in a preset door closing direction; then the stall current detection module detects the current of the drive motor, and determines whether the drive motor is stalled according to the current of the drive motor, and sends a reverse configuration signal to the control module when the drive motor is stalled; the control module reversely sets the preset door opening direction and the preset door closing direction according to the reverse configuration signal and saves the reverse setting. Therefore, in actual use, it is only necessary to install the smart lock on the door, and then close the door, the door opening and closing detection module sends a door closing signal, and the control module controls the drive motor to drive the lock tongue to rotate in a preset door closing direction. When the installation direction of the smart lock is consistent with the preset direction, the drive motor will not stall; when the installation direction of the smart lock is inconsistent with the preset direction, due to the limitation of the mechanical parts of the lock body, the lock tongue cannot continue to retract inward, and the drive motor stalls. The stall current detection module sends a reverse configuration signal after detecting the stall, and the control module reversely sets the preset door opening direction and the preset door closing direction according to the reverse configuration signal and saves the reverse setting, so that there is no need to manually set the door opening direction, and it is more convenient to use and adjust.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
