[0001] The present invention relates to the technical field of smart locks, and in particular to a method for locking a door and cutting off power supply through a smart lock. Background Art
[0002] If the power supply is not turned off after people leave the room, there will be a series of potential hazards. First, it will increase the risk of fire. Many electrical equipment are prone to overheating or quality problems when powered on for a long time, which can easily cause fires. Secondly, it will waste electricity, and long-term power outages may also affect the stability and safety of the electrical system. Therefore, a solution is urgently needed to cut off the power supply in the room as long as the door is locked after people leave the room. Summary of the invention

[0004] In order to achieve the above-mentioned purpose, the present invention provides a method for realizing door locking and power off through a smart lock, based on a lock body; When the user closes the lock and lifts the outer handle, the main lock tongue of the lock body pops out; When the user lifts the outer handle outside, the clutch arranged on the lock body triggers the first detection switch, and the first detection switch sends a lock-closing signal to the main circuit board; After the main circuit board receives the lock signal, the drive motor works, and the push rod on the motor drops and separates from the clutch, so that the outer handle is in a free state; The outer handle in the free state is separated from the main lock tongue, forming a locked door state; The first detection switch sends a locking signal to the distribution box through the transmitting board, and the distribution box receives the power-off signal and executes a power-off action.
[0005] A preferred solution is that when the user unlocks the door, the main circuit board receives the unlock signal and drives the push rod on the motor to lift up, so that the push rod on the motor is linked with the clutch to form an unlock state; The user presses down the outer handle to rotate the clutch, which will touch the second detection switch. The second detection switch sends a power-on signal to the distribution box through the transmitting board. After receiving the power-on signal, the distribution box executes the power-on action.
[0006] The second detection switch sends an unlocking signal to the distribution box through the transmitting board, and the distribution box receives the power-on signal and performs a power-on action.
[0007] A preferred solution is that the user lifts the inner handle indoors, so that the clutch triggers the third detection switch, and the third detection switch sends an anti-lock signal to the main circuit board; After the main circuit board receives the anti-lock signal, the drive motor works, and the push rod on the motor drops and separates from the clutch, so that the outer handle is in a free state; When in the free state, the outer handle and the main lock tongue are separated, forming an anti-lock state; The user presses down the inner handle indoors, causing the clutch to trigger the fourth detection switch, which sends an unlocking signal to the main circuit board; After the main circuit board receives the unlocking signal, the drive motor works, and the push rod on the motor descends and contacts the clutch, so that the outer handle is in the normally open mode.
[0008] A preferred solution is that the outer handle and the inner handle are not linked to each other.
[0009] A preferred solution is that the main circuit board also includes a locking signal port for transmitting a door locking action signal of lifting the outer handle to the main circuit board, and the locking signal port is communicatively connected to the first detection switch.
[0010] A preferred solution is to further include a front panel, wherein a front panel bracket and a transmitting plate are installed inside the front panel, and the first detection switch and the second detection switch are both installed on the front panel bracket; The main circuit board also includes a power supply port for supplying power to the transmitter board; The transmitting board includes a first transmitting port, a second transmitting port and a power receiving port; The first transmitting port is communicatively connected to the first detection switch, and the first transmitting port is used to receive a lock signal from the first detection switch; The second transmitting port is communicatively connected to the second detection switch, and the second transmitting port is used to receive an unlocking signal from the second detection switch; The power receiving port is electrically connected to the power supply port of the main circuit board.
[0011] A preferred solution is that it further comprises a rear panel, wherein a rear panel bracket, a control panel and a power supply module are arranged inside the rear panel; The power supply module is electrically connected to the main circuit board and the control board respectively; The fourth detection switch and the third detection switch are both mounted on the rear plate bracket; The control board includes a power port, an output port, a first input port, and a second input port; The power port is electrically connected to the power supply module; The output port is connected to the main circuit board for communication. The output port is used to control the forward or reverse rotation of the motor. The first input port is used to control the forward rotation of the motor and is communicatively connected with the fourth detection switch; The second input port is used to control the reverse rotation of the motor and is communicatively connected with the third detection switch.
[0012] A preferred solution is that the distribution box is installed with a wireless controller, and the wireless controller is respectively connected to the first detection switch and the second detection switch for communication; The first detection switch sends a lock signal to the transmitting board, the transmitting board sends a power-off instruction, the distribution box receives the power-off signal through the wireless controller, and executes the power-off action; The second detection switch sends an unlocking signal to the transmitting board, the transmitting board sends a power-on instruction, the distribution box receives the power-on signal through the wireless controller, and executes the power-on action.
[0013] A preferred solution is that the lock body is a wooden door smart lock or an anti-theft door smart lock.
[0014] The beneficial effects of the above scheme are: Compared with the ordinary circuit board in the prior art, the main circuit board has an additional function of changing the normally closed mode to the normally open mode. The ordinary smart lock is in a locked state under normal conditions and automatically locks back after unlocking. This is the normally closed mode. After the scheme is changed to the normally open mode, it is normally unlocked. The mechanical action of pressing down the outer handle can unlock the door. Through the lifting action or the pressing action of the outer handle, the outer handle drives the rotation of the clutch, and the rotation of the clutch touches the first detection switch or the second detection switch respectively. When a person needs to lock the door after leaving the room, the user lifts the outer handle, the main lock tongue of the lock body pops out, and the clutch triggers the first detection switch. The first detection switch gives the main circuit board a lock signal, and the main circuit board then controls the output shaft of the motor to rotate counterclockwise. The output shaft of the motor drives the top rod to descend and separate from the clutch. At this time, the outer handle becomes free. When the user turns the outer handle in the free state, the clutch cannot drive the lock tongue of the lock body to extend and retract, thus forming a locked door state. At the same time, the first detection switch also gives the transmitter a lock signal, and the transmitter transmits a power-off communication signal. The distribution box receives the communication signal and performs a power-off action.
[0015] The solution of shutting off the power in the room as long as the door is locked after the person leaves the room has the following advantages: 1. Automatically cut off the power supply when no one is in the room, which can effectively reduce unnecessary energy waste, such as the operation or standby power consumption of lighting, air conditioning, television and other electrical appliances, and improve energy saving and consumption reduction.
[0016] Second, power outages can reduce the risk of fire, especially when the place is left unattended for a long time, such as apartments, offices, hotel rooms, etc.
[0017] 3. Frequent power on and off may cause damage to some electronic equipment, but this solution can reduce the wear and tear of the equipment without affecting normal use.
[0018] 4. In the long run, the saved electricity bills can bring considerable economic benefits to individuals or enterprises. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical scheme in the embodiment of the present invention is described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0023] First embodiment: like Figure 1 and Figure 2 As shown, this embodiment provides a method for locking a door and cutting off power through a smart lock, based on a lock body 1; wherein, Figure 1 It is a schematic diagram of the lock body 1 in the locked state.
[0024] When the user locks the door, he lifts the outer handle 21 outdoors, and the main lock tongue of the lock body 1 pops out (the main lock tongue will pop out only when the handle is lifted, and the active lock tongue is mechanically ejected). Lifting the outer handle 21 causes the clutch 22 set in the lock body 1 to touch the first detection switch 23, and the first detection switch 23 sends a lock signal to the main circuit board 24. After receiving the lock signal, the main circuit board 24 drives the motor 25 to work, and the top rod 27 on the motor 25 descends and separates from the clutch 22, so that the outer handle 21 is in a free state. The outer handle 21 in the free state is in a separated state from the main lock tongue, forming a locked door state. The first detection switch 23 sends a lock signal to the distribution box through the transmitting board 28, and the distribution box receives the power-off signal, and the distribution box performs a power-off action.
[0025] The main circuit board 24 also includes a lock signal port 241 for transmitting the door lock action signal of lifting the outer handle 21 to the main circuit board 24, and the lock signal port 241 is communicatively connected with the first detection switch 23. The present invention also includes a front panel 2, and a front panel bracket 29 and a transmitting board 28 are installed inside the front panel 2, and the first detection switch 23 and the second detection switch 26 are both installed on the front panel bracket 29. The main circuit board 24 also includes a power supply port 240 for supplying power to the transmitting board 28. The transmitting board 28 includes a first transmitting port 280, a second transmitting port 281 and a power receiving port 281. The first transmitting port 280 is communicatively connected with the first detection switch 23, and the first transmitting port 280 is used to receive the lock signal sent by the first detection switch 23. The second transmitting port 281 is communicatively connected with the second detection switch 26. The second transmitting port 281 is used to receive the unlocking signal of the second detection switch 26, and the power receiving port 281 is electrically connected with the power supply port of the main circuit board 24.
[0026] The main circuit board 24 has the following additional functions compared to the common circuit boards in the prior art: changing the normally closed mode to the normally open mode, wherein the common smart lock is in the locked state under normal conditions, and automatically locks back after unlocking, which is the normally closed mode. After the scheme is changed to the normally open mode, it is normally unlocked, and the mechanical action of pressing down the outer handle 21 can unlock. By the lifting action or pressing down action of the outer handle 21, the outer handle 21 drives the rotation of the clutch 22, and the rotation of the clutch 22 touches the first detection switch 23 or the second detection switch 26 respectively.
[0027] Further explanation is that after locking the door, the outer handle 21 is in a free state, and pressing down the outer handle 21 cannot drive the clutch 22 to rotate. Therefore, when the door is not unlocked, pressing down the outer handle 21 will not touch the second detection switch 26 and cannot be powered on. In addition, the first detection switch 23 and the second detection switch 26 only respond to the touch action once, and only by touching the corresponding first detection switch 23 and the second detection switch 26 can the door be unlocked and react again. Therefore, multiple touches of the first detection switch 23 and the second detection switch 26 cannot transmit communication signals and will not generate unnecessary power consumption. When a person needs to lock the door after leaving the room, the user lifts the outer handle 21, the main lock tongue of the lock body 1 pops out, the clutch 22 triggers the first detection switch 23, the first detection switch 23 gives a lock signal to the main circuit board 24, the main circuit board 24 then controls the output shaft of the motor 25 to rotate counterclockwise, the output shaft of the motor 25 drives the push rod 27 to descend and separate from the clutch 22, at this time the outer handle 21 becomes free, when the user turns the outer handle 21 in the free state, the clutch 22 cannot drive the lock tongue of the lock body to extend and retract, thus forming a locked door state. At the same time, the first detection switch 23 also gives a lock signal to the transmitting board 28, the transmitting board 28 transmits a power-off communication signal, and the distribution box receives the communication signal to perform a power-off action.
[0028] The solution of shutting off the power in the room as long as the door is locked after the person leaves the room has the following advantages: 1. Automatically cut off the power supply when no one is in the room, which can effectively reduce unnecessary energy waste, such as the operation or standby power consumption of lighting, air conditioning, television and other electrical appliances, and improve energy saving and consumption reduction.
[0029] Second, power outages can reduce the risk of fire, especially when the place is left unattended for a long time, such as apartments, offices, hotel rooms, etc.
[0030] 3. Frequent power on and off may cause damage to some electronic equipment, but this solution can reduce the wear and tear of the equipment without affecting normal use.
[0031] 4. In the long run, the saved electricity bills can bring considerable economic benefits to individuals or enterprises.
[0032] When the user unlocks the door, the main circuit board 24 receives the unlock signal and drives the top rod 27 on the motor 25 to lift up, so that the top rod 27 on the motor 25 is linked with the clutch 22 to form an unlocked state. The user presses down on the external handle 21 to rotate the clutch 22, and the clutch 22 touches the second detection switch 26. The second detection switch 26 sends a power-on signal to the distribution box through the transmitting board 28. The distribution box receives the power-on signal and performs the power-on action. The second detection switch 26 sends an unlock signal to the distribution box through the transmitting board 28. The distribution box receives the power-on signal and performs the power-on action.
[0033] When unlocking by fingerprint, password, card or other unlocking methods, the main circuit board 24 will control the output shaft of the motor 25 to rotate clockwise, and the motor 25 will drive the push rod 27 to move upward and contact the clutch 22 to form an unlocked state. The downward pressure of the outer handle 21 will drive the clutch 22 to rotate, and the clutch 22 will touch the second detection switch 26. The second detection switch 26 transmits an unlocking signal to the transmitting board 28, and the transmitting board 28 transmits a power-on communication signal. After receiving the signal, the distribution box executes the power-on action.
[0034] Second embodiment: When the user lifts the inner handle 31 indoors, the clutch 22 triggers the third detection switch 32, and the third detection switch 32 sends a lock signal to the main circuit board 24. After receiving the lock signal, the main circuit board 24 drives the motor 25 to work, and the top rod 27 on the motor 25 drops and separates from the clutch 22, so that the outer handle 21 is in a free state. In the free state, the outer handle 21 is separated from the main lock tongue, forming an anti-lock state (the outer handle 21 is separated from the main lock tongue, the door cannot be opened from the outside, and the indoor handle can be unlocked at any time). When the user presses down the inner handle 31 indoors, the clutch 22 triggers the fourth detection switch 33, and the fourth detection switch 33 sends an unlock signal to the main circuit board. After receiving the unlock signal, the main circuit board 24 drives the motor 25 to work, and the top rod 27 on the motor 25 drops and contacts the clutch 22, so that the outer handle 21 is in a normally open mode.
[0035] The present invention also includes a rear panel 3, and a rear panel bracket 34, a control panel 35 and a power supply module 36 are arranged inside the rear panel 3. The power supply module 36 is electrically connected to the main circuit board 24 and the control panel 35 respectively. The rear panel bracket 34 is installed on the upper end of the connection plate inside the inner handle 31, and the fourth detection switch 33 and the third detection switch 32 are both installed on the rear panel bracket 34. The control panel 35 includes a power port 350, an output port 351, a first input port 352 and a second input port 353. The power port 350 is electrically connected to the power supply module 36. The output port 351 is connected to the communication of the main circuit board 24, and the output port 351 is used to control the forward or reverse rotation of the motor 25. The first input port 352 is used to control the forward rotation of the motor 25, and the first input port 352 is connected to the fourth detection switch 33 for communication. The second input port 353 is used to control the reverse rotation of the motor 25, and the second input port 353 is connected to the third detection switch 32 for communication.
[0036] Because the lock in this solution is in the normally open mode, the main lock tongue pops out after the inner handle 31 is lifted indoors, but pressing down the outer handle at this time will open the lock, and the anti-lock function cannot be achieved. The solution is to add a control board 35 inside the rear panel 3. When the inner handle 31 is lifted indoors, the internal connecting plate of the inner handle 31 will touch the third reverse detection switch 32, and the control board 35 will receive the reverse signal, and then control the motor 25 to reverse through the motor port on the main circuit board 24. The top rod 27 on the motor 25 is disengaged from the clutch 22, and the lock is converted into a locked door state, so that the anti-lock function can be achieved. When the inner handle 31 is pressed down when unlocking the door, the connecting plate of the inner handle 31 will touch the fourth forward detection switch 33, the motor 25 will rotate forward, and the top rod 27 of the motor 25 will contact the clutch 22, and the normally open mode will be restored.
[0037] It should be noted that ordinary smart locks are in normally closed mode. Closing the door is locking the door. You need to unlock it again when you want to unlock it. It will automatically lock again after a few seconds. If an outsider visits after closing the door, the person inside needs to unlock it. It is troublesome to use and the smart lock itself consumes a lot of energy. In this method, the main circuit board 24 control mode is normally open mode. The mechanical action of pressing down the outer handle outdoors can unlock the door. No energy is consumed each time. Therefore, it is very suitable for use in public institutions. It is simple and convenient and can save a lot of battery consumption.
[0038] The fourth detection switch 33 and the third detection switch 32 only respond to the touch action once, and only by touching the corresponding fourth detection switch 33 and the fourth detection can the lock be unlocked and reacted again, so touching the same detection switch multiple times will not generate unnecessary power consumption.
[0039] The outer handle 21 and the inner handle 31 are not linked to each other. When the inner handle 31 is lifted indoors, it cannot be linked to the outer handle 21 outdoors, otherwise the outer handle 21 will be powered off. The solution is to use a customized lock body, and the outer handle 21 and the inner handle 31 independently control the lock body and lock tongue, without any linkage and without interfering with each other's functions.
[0040] This method is also applicable to anti-theft door smart locks. After being applied to anti-theft door smart locks, it will show better advantages. Figure 3 As shown, the anti-theft door smart lock is equipped with a standard 6068 lock body, which has three lock tongues, namely the live lock tongue 10, the main lock tongue 11 and the safety lock tongue 12. When it is necessary to reverse lock, twist the safety lock tongue 12, and the lock cannot be opened from the outside, so as to achieve the reverse lock effect. However, no one outside can open the lock, even if various unlocking methods including mechanical keys are used. This situation can still be used at home, but it is very unfriendly to use it in public institutions. First of all, there are many people in the office, and this function cannot be used. It is necessary to ensure that the administrator can open the lock to ensure the sharing and safety of public places. Secondly, in the case of reverse lock, in case of emergency such as fire and earthquake, personnel are required to quickly unlock the lock and realize one-press escape, but it is easy to misoperate and waste precious escape time in a panic.
[0041] After the scheme is applied to the intelligent lock of the anti-theft door, the safety lock tongue 12 can be discarded, and the person with unlocking authority can always open the lock, and the one-press escape function can be realized when the lock is reversed.
[0042] The distribution box is equipped with a wireless controller, which is respectively connected to the first detection switch 23 and the second detection switch 26. The first detection switch 23 sends a lock signal to the transmitting board 28, the transmitting board 28 sends a power-off instruction, the distribution box receives the power-off signal through the wireless controller, and performs the power-off action. The second detection switch 26 sends an unlock signal to the transmitting board 28, the transmitting board 28 sends a power-on instruction, the distribution box receives the power-on signal through the wireless controller, and performs the power-on action.
[0043] Other embodiment 1: like Figure 1-Figure 4 As shown, this embodiment includes a main circuit board 24, a transmitting board 28, a first detection switch 23, a micro switch 40, a control board 35 and various connecting wires integrated into the front and rear panels of the smart lock.
[0044] The main circuit board 24 adds three functions on the basis of the ordinary circuit board: first, the normally closed mode is changed to the normally open mode. The ordinary smart lock is in the locked state under normal circumstances, and it automatically locks again after being unlocked for a few seconds. This is the normally closed mode. After changing to the normally open mode, it is normally unlocked. The door can be opened by pressing down the handle; second, a lock signal port 241 is added, and the lock signal port 241 is connected to the first detection switch 23 to transmit the lock action signal of the lifting handle to the main circuit board 24; third, a power supply port 350 is added to power the transmitting board 28.
[0045] The transmitting board 28 is a circuit board for receiving command transmission communication signals. There are two ports on the transmitting board 28, one of which is connected to the micro switch 40. The micro switch 40 is installed under the top rod 27. The micro switch 40 is used to transmit the command signal of the locking or unlocking state to the transmitting board 28. The other port is a power receiving port, which is electrically connected to the power supply port added to the main circuit board 24.
[0046] The control board 35 is installed on the rear four ports, one of which is the power port 350. One is inside the signal output terminal panel and is connected to the motor 25 port of the main circuit board 24 for controlling the forward and reverse rotation of the motor 25. The other two ports are the forward and reverse signal input ports, each of which is connected to a first detection switch 23. The two first detection switches 23 are respectively installed at the two ends of the front plate bracket 29, and the front plate bracket 29 is installed on the upper end of the internal connection plate of the outer handle. The pressing down and lifting up of the handle touch the two first detection switches 23 respectively, and the first detection switch 23 will give the control board 35 a forward or reverse signal, and the control board 35 will then transmit the forward or reverse signal to the motor 25 through the signal output port.
[0047] The usage scenario is as follows: independent of the door lock, a wireless controller is installed on the control line in the indoor distribution box. The door lock sends a communication signal to cut off or supply power, and the wireless controller receives the communication signal and then executes the power-off or power-on action.
[0048] First of all, it should be noted that ordinary smart locks lock the door when closing it, and need to be unlocked again when opening the door. It will automatically lock again after a few seconds of unlocking. If an outsider visits after closing the door, the person inside needs to open the door, which is troublesome to use and the smart lock itself consumes a lot of energy. The 24-control mode of the main circuit board of this lock is the normally open mode. The mechanical action of pressing down the handle can open the door, and no energy is consumed each time. Therefore, it is very suitable for use in public institutions, which is simple and convenient and can save a lot of battery consumption.
[0049] The principle of this smart lock to control the power-off and power-on of locking and unlocking is as follows: when a person leaves the room and locks the door, he needs to lift the outer handle, and the outer handle connecting plate will trigger the first detection switch 23. The first detection switch 23 gives a lock signal to the main circuit board 24, and the main circuit board 24 then controls the motor 25 to reverse, and the top rod 27 of the motor 25 descends to disengage the clutch, forming a locked door state. At the same time, the descent of the top rod 27 of the motor 25 presses the micro switch 40 at the bottom, and the micro switch 40 gives a power-off signal to the transmitting board 28. At this time, the main circuit board 24 is in the awakening state when locking the door, that is, the power-on state, and will supply power to the transmitting board 28, so the transmitting board 28 transmits a power-off communication signal, and the controller in the distribution box receives the communication signal and performs the power-off action.
[0050] On the contrary, when unlocking by fingerprint, password, card or other unlocking methods, the main circuit board 24 is awakened and is in the power-on state, the control motor 25 rotates forward and supplies power to the transmitting board 28, the motor 25 push rod 27 moves upward and contacts the clutch, forming an unlocked state, and at the same time the push rod 27 is disengaged from the micro switch 40, the micro switch 40 transmits a signal to the transmitting board 28, and in the power-on state, the transmitting board 28 transmits a power-on communication signal, and the controller executes the power-on action after receiving the signal.
[0051] This is the whole process of powering off when locking the door and powering on when unlocking the door. Although this function is realized, due to the addition of some components in the smart lock panel, there will be some impact on the use of other functions of the smart lock. Most public institutions use wooden door smart locks, and the lock body of the wooden door has only two lock tongues, namely the active lock tongue and the main lock tongue. Because ordinary wooden door smart locks are in normally closed mode, when locking the door indoors, lift the handle to pop out the main lock tongue, and it cannot be opened from the outside, which means it is in the reverse locked state.
[0052] However, this lock is in the normally open mode. After the handle is lifted indoors, although the main lock tongue pops out, pressing the handle outside the door will open the lock, and the anti-lock function cannot be realized. The solution is to add a control board 35 inside the rear panel. The control line of the motor 25 port on the main circuit board 24 is divided into two paths, one connected to the motor 25, and the other connected to the signal output end on the control board 35, which is equivalent to that both the main circuit board 24 and the control board 35 can control the forward and reverse rotation of the motor 25. When the handle is lifted indoors, the internal handle connection board will touch the reverse first detection switch 23, the control board 35 receives the reverse signal, and then controls the motor 25 to reverse through the signal output port of the control board 35. The top rod 27 of the motor 25 drops, and the lock is converted into the locked door state. Although the top rod 27 of the motor 25 presses the micro switch 40, the main circuit board 24 is not awakened at this time, and the transmitting board 28 will not be powered. The transmitting board 28 does not transmit a 433MHZ signal, so there will be no power failure in the room, and normal anti-locking can be achieved. The principle of indoor unlocking of ordinary smart locks and this lock is the same. You only need to press down the handle to open the door. At the same time, the handle connecting plate of this lock will touch the first forward detection switch 23. Similarly, the motor 25 will return to the normally open mode after forward rotation. And the two first detection switches 23 only react once when interlocking. There will be no reaction when the indoor door is opened and the first detection switch 23 is touched again, and no power consumption will be generated. This method solves the problem of indoor reverse locking of this lock, and it is no different from the use of ordinary smart locks.
[0053] Another problem is that the indoor handle cannot be linked with the outdoor handle when it is lifted, otherwise the power will be cut off. The solution is to use a customized lock body, and the inner and outer handles control the lock body independently, without linkage and without interfering with each other's functions.
[0054] Other Embodiment 2: The purpose of the smart lock using this method is to cut off the power when locking the door, and to supply power when unlocking. However, if you want to selectively cut off the power in some occasions, it can also be realized. That is, when you do not want to cut off the power, closing the door is to lock the door, and when you want to cut off the power, lifting the outer handle 21 can cut off the power, and the power can be supplied after unlocking.
[0055] The main circuit board 24 remains unchanged and is the same as an ordinary smart lock. The only parts added are the front plate bracket 29, the first detection switch 23, the second detection switch 26 and the transmitter board 28. The power supply module 36 also has two lines, one for the main circuit board 24 and the other for the transmitter board 28. The lock body also uses a customized lock body, and the inner and outer handles 21 independently control the lock body and the lock tongue, without any linkage and without mutual interference of functions.
[0056] The working principle is as follows: ordinary smart locks are in normally closed mode. Closing the door is locking the door. When you want to cut off the power, you need to lift the outer handle 21, the main lock tongue of the lock body pops out, and after the clutch 22 touches the first detection switch 23, the transmitting plate 28 transmits a power-off signal. After unlocking, press the outer handle 21 down to touch the second detection switch 26, and the transmitting plate 28 transmits a power-on signal. Lift the inner handle 31 indoors, the main lock tongue pops out, because the smart lock is in normally closed mode, forming an anti-lock state.
[0057] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
