[0030] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this disclosure. Therefore, the drawings and description are to be considered exemplary in nature and not restrictive.

[0031] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0032] This disclosure proposes a door lock, a smart door, and a control method for the smart door. When an external object is inserted into the keyhole and actuates the pin tumbler assembly within it, the pin tumbler assembly contacts a detection probe. This causes a detection circuit connected to the detection probe to generate an electrical signal, which is used to sense the unlocking action, thus improving the door lock's security. This prevents situations where the homeowner is unaware of unauthorized attempts to open the lock, giving the perpetrator ample time to do so.

[0033] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Figure 1 A schematic diagram of the structure of a door lock according to an embodiment of the present disclosure is shown, such as... Figure 1 As shown, the door lock 100 includes at least: a lock cylinder body 110 and a first circuit board 120.

[0035] The lock cylinder body 110 includes multiple spring slots 111, each spring slot 111 is provided with a pin assembly 112, and at least some of the pin assemblies 112 are provided with a detection probe 113.

[0036] The first circuit board 120 is disposed on the lock cylinder body 110. The detection probe 113 is connected to the detection circuit of the first circuit board 120. The detection circuit is used to generate a corresponding electrical signal when the pin assembly 112 is lifted to contact the detection probe 113.

[0037] It should be noted that the use of a pin tumbler lock cylinder structure in this embodiment is an example and not a limitation. In actual application scenarios, the lock cylinder body 110 can adopt various common lock cylinder structures, such as pin tumbler lock cylinders, leaf lock cylinders, side pin lock cylinders, etc., which are not limited here.

[0038] The number of spring slots 111 can be adjusted as needed and is not limited here. For example, the lock cylinder body 110 can have 6 spring slots 111 arranged side by side.

[0039] The first circuit board 120 can be a printed circuit board (PCB), which is fixed to the surface of the lock cylinder body 110. For easy connection with the detection probe 113, the PCB can be positioned on top of the spring slot 111. Alternatively, the PCB can be positioned on the side of the lock cylinder body 110, and the detection probe 113 can be connected to the PCB via wires. The PCB can be fixed to the lock cylinder body 110 using screws. A wire harness 140 extends from the PCB, including several wires for connection to other devices, such as a processor, power supply, or main control device. The PCB includes a detection circuit with multiple contacts. The detection probe 113 connects to these contacts. When the spring assembly 112 is raised to contact the detection probe 113, the detection circuit can conduct at least two contacts through the detection probe 113 and the spring assembly 112, thereby generating a corresponding electrical signal.

[0040] According to the scheme of this disclosure embodiment, by setting a detection probe 113 in the tumbler 111, when the tumbler assembly 112 comes into contact with the detection probe 113, the detection circuit generates an electrical signal. The door lock can monitor the unlocking process using the electrical signal. Specifically, it can at least detect the insertion of an external object into the lock cylinder.

[0041] Figure 2 This is a structural schematic diagram of the ball component 112 according to an embodiment of the present disclosure, combined with... Figure 1 and Figure 2 As shown, in one possible implementation, the pin assembly 112 includes a pin 1121, a first elastic element 1122, and a fixing element 1123. The pin 1121 is located near the lock hole of the lock cylinder body 110, and the fixing element 1123 is located near the first circuit board 120. The first elastic element 1122 is located between the pin 1121 and the fixing element 1123. The detection probe 113 includes a first needle rod 1131, a second needle rod 1132, and a second elastic element 1133. The first needle rod 1131 and the second needle rod 1132 are movably connected through the second elastic element 1133. The first needle rod 1131 passes through the first elastic element 1122, and the pin 1121 can be lifted to contact the first needle rod 1131. The second needle rod 1132 passes through the fixing element 1123 and is connected to the detection circuit.

[0042] It should be noted that the pin 1121 includes two parts: a lower pin (also called a lower spring or lower ball) and a flat-head pin (also called an upper spring or upper ball). The lower pin is located near the lock hole of the lock cylinder body 110, and the flat-head pin is located between the lower pin and the first elastic element 1122. In some lock cylinder types, there may be multiple flat-head pins in some pin slots 111.

[0043] According to the scheme of the present disclosure embodiment, after the ball 1121 is raised to contact the lower end of the detection probe 113, the detection probe 113 can maintain contact with the ball 1121 during the movement within a certain range, and reset after the ball 1121 leaves.

[0044] In one example, one of the first needle bar 1131 and the second needle bar 1132 has an axially oriented circular hole at its first end. The inner diameter of the circular hole is larger than the outer diameter of the other needle bar. A second elastic element 1133 is provided inside the circular hole. The first end of the other needle bar is inserted into the circular hole and connected to the second elastic element 1133. The second elastic element 1133 can be a spring or a spring sheet. For example, the lower end of the second needle bar 1132 has a circular hole, and the upper end of the first needle bar 1131 is inserted into the circular hole at the lower end of the second needle bar 1132. The top of the first needle bar 1131 is connected to the bottom surface of the circular hole at the lower end of the second needle bar 1132 via a spring. The first needle bar 1131 can move axially within the circular hole of the second needle bar 1132, and after movement, it can return to the equilibrium position under the restraint of the spring.

[0045] Still as Figure 2 As shown, in one possible implementation, the surface of the second needle bar 1132 is provided with an insulating layer 1134.

[0046] It should be noted that the height of the insulating layer 1134 can be greater than the height of the fixing member 1123, and completely cover the area where the detection probe 113 contacts the fixing member 1123. The insulating layer 1134 can be made of rubber or plastic, or any other material with low conductivity.

[0047] According to the scheme of the present disclosure embodiment, the interference of other currents on the detection probe 113 is eliminated by the insulating layer 1134, so that the detection circuit connected to the detection probe 113 can accurately generate an electrical signal based on the contact between the detection probe 113 and the ball 1121.

[0048] Figure 3 This is a structural schematic diagram of the spring groove portion according to an embodiment of the present disclosure, as shown below. Figure 3As shown, in one possible implementation, the tumbler 111 includes a first tumbler 111a. A first detection probe 113a is disposed in the ball assembly 112 within the first tumbler 111a. The first end of the first detection probe 113a is connected to a first contact of the detection circuit. The ball assembly 112 within the first tumbler 111a is connected to a second contact of the detection circuit. When the second end of the first detection probe 113a contacts the ball assembly 112 within the lifted first tumbler 111a, the first contact and the second contact are connected, and the detection circuit generates a first electrical signal.

[0049] In this embodiment of the disclosure, the first spring groove 111a can be the outermost spring groove in the keyhole. When an external object is inserted into the keyhole, it will first come into contact with the tumbler assembly 112 in the first spring groove 111a. The outermost tumbler assembly 112 is also more easily triggered.

[0050] The fixing member 1123 in the ball assembly 112 in the first ball groove 111a is connected to the second contact of the detection circuit. When the second end of the first detection probe 113a contacts the ball assembly 112 in the lifted first ball groove 111a, the first contact sequentially passes through the first detection probe 113a, the ball 1121 in the ball assembly 112, the first elastic member 1122, and the fixing member 1123 before connecting to the second contact. The second contact can be a ground point. When the first contact and the second contact are connected, the voltage of the first contact drops, thereby generating a first electrical signal.

[0051] According to the scheme of this embodiment, when the ball 1121 in the first ball groove 111a is touched by an external object, the detection circuit can generate a first electrical signal, which can be used to sense whether an external object has been inserted into the keyhole.

[0052] In one possible implementation, such as Figure 3 As shown, the tumbler 111 includes a second tumbler 111b. A second detection probe 113b is inserted through the ball assembly 112 in the second tumbler 111b. The first end of the second detection probe 113b is connected to the third contact of the detection circuit. The second end of the first detection probe 113a contacts the ball assembly 112 in the first tumbler 111a that is lifted by a metal object. When the second end of the second detection probe 113b contacts the ball assembly 112 in the second tumbler 111b that is lifted by a metal object, the third contact is connected to the second contact through the metal object, and the detection circuit generates a second electrical signal.

[0053] In this embodiment, the second spring groove 111b can be the spring groove inside the first spring groove 111a. When the third contact is connected to the second contact, it indicates that a conductive metal object is inserted into the keyhole. Since the tumbler assembly 112 inside the keyhole is not easily touched by external objects, the repeated generation of the second electrical signal may indicate an abnormal situation. According to a preset setting, an alarm message can be generated under certain conditions. For example, it can be set to generate an alarm message if the number of times the second electrical signal is generated reaches 3 within 3 seconds. The abnormal situation may be that a criminal is trying to unlock the door, or that the homeowner is being coerced and deliberately inserting and removing the key multiple times in an attempt to generate an alarm message to call for help.

[0054] According to the embodiment of this disclosure, the second spring groove 111b can cooperate with the first spring groove 111a, so that the second electrical signal can be used to detect whether the inserted object is a metal object. Furthermore, it can be determined whether the homeowner may be coerced by criminals.

[0055] In one possible implementation, such as Figure 3 As shown, the tumbler 111 includes a second tumbler 111b. A second detection probe 113b is inserted through the ball assembly 112 in the second tumbler 111b. The first end of the second detection probe 113b is connected to the third contact of the detection circuit. The ball assembly 112 in the second tumbler 111b is connected to the fourth contact of the detection circuit. When the second end of the second detection probe 113b contacts the ball assembly 112 in the raised second tumbler 111b, the third contact and the fourth contact are connected, and the detection circuit generates a second electrical signal.

[0056] According to the scheme of this disclosure embodiment, a second electrical signal can be generated even when only the ball assembly 112 of the second ball groove 111b is touched.

[0057] Figure 4 yes Figure 3 A magnified view of the area at position E in the middle, combined with Figure 3 and Figure 4 In one possible implementation, the ball slot 111 includes a third ball slot 111c, and a third detection probe 113c is disposed in the ball assembly 112 within the third ball slot 111c. The first end of the third detection probe 113c is connected to the fifth contact of the detection circuit.

[0058] like Figure 4 As shown, it also includes a key 130. The key 130 has a key end resistor 131 on its teeth. When the key 130 is inserted into the lock cylinder body 110, the second end of the third detection probe 113c contacts the tumbler assembly 112 in the third tumbler groove 113c that is lifted by the key 130. The fifth contact is connected to the second contact through the key 130 and the key end resistor 131, and the detection circuit generates a third electrical signal.

[0059] In this embodiment, the third spring groove 113c can be the innermost spring groove of the keyhole, which is least likely to be accidentally activated. When the fifth contact is connected to the second contact via the key 130 and the key-end resistor 131, the voltage value of the fifth contact decreases due to the connection of the key-end resistor 131. If the resistance value of the key-end resistor 131 meets the preset requirement, the voltage value of the fifth contact should also meet the threshold requirement. Therefore, based on the voltage value of the third electrical signal, it can be determined whether the key-end resistor 131 on the key 130 is preset, and it can be further determined whether the key 130 is a key that matches this door lock.

[0060] According to the scheme of this embodiment, the generated third electrical signal is affected by the key end resistor 131 on the key 130, and can be used to determine whether the key 130 is matched with the door lock.

[0061] like Figure 4 As shown, in one possible implementation, the key 130 also includes a second circuit board 132, with a key end resistor 131 disposed between the second end face of the second circuit board 132 and the teeth.

[0062] At least a portion of the first end face of the second circuit board 132 is a first conductive area 1321, and at least a portion of the outer region of the second end face of the second circuit board 132 is a second conductive area 1322. A key-end resistor 131 is disposed in the inner region of the second end face of the second circuit board 132. The first end of the key-end resistor 131 is connected to the first conductive area 1321 and can be connected to the pin assembly 112 through the first conductive area 1321. The second end of the key-end resistor 131 is connected to the second conductive area 1322 and can be connected to the key 130 through the second conductive area 1322.

[0063] In this embodiment of the disclosure, the first end face is defined as Figure 4 The upper surface of the second circuit board 132 shown is defined as the second end face. Figure 4 The lower surface of the second circuit board 132 shown can have bare copper for the first and second conductive areas, and the key-end resistor 131 can be a surface-mount resistor.

[0064] According to the solution of the present disclosure embodiment, by placing the key end resistor 131 between the second circuit board 132 and the key 130, the resistor can be protected and the key life can be improved.

[0065] In one possible implementation, the two end faces of the second circuit board 132 and the inner area of ​​the second end face are connected to the key via non-conductive adhesive 134, and the second conductive area is connected to the key via conductive adhesive.

[0066] In this embodiment of the disclosure, conductive adhesive on both sides of the second circuit board 132 covers the edges of the second circuit board.

[0067] According to the scheme of this disclosure embodiment, the second circuit board 132 is firmly connected to the key by non-conductive adhesive.

[0068] Figure 5 This is a schematic diagram of the detection circuit according to an embodiment of the present disclosure, as shown below. Figure 5 In one possible implementation, the detection circuit includes: a first resistor R1, a second resistor R2, and a third resistor R3 connected in parallel. The first ends of the first resistor R1, the second resistor R2, and the third resistor R3 are connected to the same power supply. The second end of the first resistor R1 is connected to a first contact A, a first capacitor C1, and a second contact B in sequence before being grounded. The first contact A is used to connect the processor and the first detection probe 113a, and the second contact B is used to connect the ball assembly 112 of the first ball slot 111a. The second end of the second resistor R2 is connected to the third contact C1 and... The second capacitor C2 is grounded, and the third contact C is used to connect the processor and the second detection probe 113b; the second end of the third resistor R3 is connected to the fifth contact D and the third capacitor C3 in sequence and then grounded, and the fifth contact D is used to connect the processor and the third detection probe 113c; when the first detection probe 113a contacts the ball assembly 112 of the first slot 111a, the second detection probe 113b contacts the ball assembly 112 of the first slot 111b, or the third detection probe 113c contacts the ball assembly 112 of the third slot 113c, the detection circuit generates the corresponding electrical signals respectively.

[0069] In this embodiment, the first contact A, R1, C1, and the second contact B form an insertion detection circuit IN_DET, used to detect whether an external object has been inserted into the keyhole based on the voltage change of the first contact A. The third contact C, R2, and C2 form a protection detection circuit PROTECT_IN, used to perform anti-hijacking judgment based on the voltage change of the third contact C. The fifth contact D, R3, and C3 form a voltage detection circuit ID_ADC, used to measure the voltage at the fifth contact D when the key 130 is inserted into the lock, causing the key end resistor R4 to be connected to the voltage detection circuit ID_ADC. IN_DET, PROTECT_IN, and ID_ADC are connected to the processor via wires.

[0070] In one example, when no key is inserted, the detection probes corresponding to the first contact A, the third contact C, and the fifth contact D are all in a suspended state, and the springs inside the detection probes are uncompressed. When a key is inserted, the concave and convex surfaces of the key 130 push the pins 1121 below the first and second detection probes 113a and 113b upwards. At this time, the detection probes contact and are compressed with the pins 1121, and the first contact A and the second contact B are connected. The voltage at the first contact A is pulled low and transmitted to the MCU via IN_DET. The MCU can then sense the level change at the IN_DET terminal, thus determining that the key 130 has been inserted. Similarly, due to the insertion of the key 130, the key 130 is a conductor, and the third contact C and the second contact B are also connected. The MCU can then detect the voltage change at the third contact C via PROTECT_IN. Also due to the insertion of the key 130, the key-end resistor R4 on the key 130 is connected to the fifth contact D, and the MCU can then detect the voltage change at the fifth contact D via ID_ADC.

[0071] Figure 6 This is a structural block diagram of a smart door according to an embodiment of the present disclosure, such as... Figure 6 As shown in the embodiments of this disclosure, a smart door 200 is also provided, which includes at least: a door lock 100 and a processor 210 as described in any of the above embodiments. The processor 210 is connected to the detection circuit of the door lock 100 and is used to acquire the electrical signal generated by the detection circuit. In one example, the processor 210 may be a microcontroller unit (MCU).

[0072] In one possible implementation, the smart door 200 also includes:

[0073] Alarm 220, connected to processor 210, is used to emit an alarm sound. Alarm 220 can be any existing device with alarm function, and no specific limitation is made here.

[0074] The door open / close detector 230, connected to the processor 210, is used to generate a door open / close status signal based on the distance between the door frame and the door panel of the smart door. The door open / close detector 230 can be any existing device with alarm functionality; no specific limitation is made here.

[0075] The wireless communication module 240, connected to the processor 210, is used to transmit information, including at least one of alarm information, unlocking information, and key insertion information. The wireless communication module 240 can be any existing device with alarm functionality, and no specific limitation is made herein.

[0076] Figure 7This is a schematic flowchart illustrating the implementation of a control method for an intelligent door according to an embodiment of this disclosure. This method can be applied to the aforementioned intelligent door 200, such as... Figure 7 As shown, the method includes at least the following steps:

[0077] S701: Acquire an electrical signal generated by the detection circuit when the ball assembly is lifted to contact the detection probe;

[0078] S702: Determine the number of times the electrical signal is acquired within a preset time period, and generate an alarm message if the number of acquisitions exceeds a threshold.

[0079] According to the scheme of this disclosure embodiment, the electrical signal is generated when the pin tumbler assembly is lifted to contact the detection probe. The door lock can use the electrical signal to monitor whether there is any abnormality in the unlocking process. Specifically, during normal unlocking, the number of times the electrical signal is generated is usually once. If the number exceeds the threshold, it means that the pin tumbler assembly is repeatedly touched, and there may be a situation where the door lock is being technically opened.

[0080] In one example, the control method for the smart door can be executed by a processor. Specifically:

[0081] The processor acquires an electrical signal generated by the detection circuit when the ball assembly is lifted to contact the detection probe;

[0082] The processor determines the number of times the electrical signal is acquired within a preset time period. If the number of acquisitions exceeds a threshold, an alarm message is generated.

[0083] The description of the electrical signal generation method, detection circuit structure and examples of the embodiments of this disclosure can be found in the corresponding descriptions in the above structural embodiments, and will not be repeated here.

[0084] In one possible implementation, the electrical signal includes a first electrical signal, and step S702 further includes:

[0085] S801: In response to the first electrical signal, determine the number of times the first electrical signal is acquired within a first preset time length, wherein the first electrical signal is generated when the first contact and the second contact in the detection circuit are turned on;

[0086] S802: If the number of times the first electrical signal is acquired exceeds the first threshold, generate the first alarm information.

[0087] In this embodiment of the disclosure, a first electrical signal can be used to wake up the processor. Prolonged keyless insertion allows the processor to run a low-power management mechanism, reducing energy consumption. The processor is woken up once the first electrical signal is detected.

[0088] In one example, if more than five initial electrical signals are detected within three seconds, a first alarm message is generated. This first alarm message can be understood as the detection of multiple attempts by an external object to insert into the lock, suggesting that a criminal may be attempting to open the lock. Setting a first threshold prevents accidental alarm activation.

[0089] In one possible implementation, the electrical signal includes a second electrical signal, and step S702 further includes:

[0090] S803: In response to the second electrical signal, determine the number of times the second electrical signal is acquired within a second preset time length, wherein the second electrical signal is generated when the third contact in the detection circuit is connected to the second contact;

[0091] S804: If the number of times the second electrical signal is acquired exceeds the second threshold, generate a second alarm message.

[0092] In one example, since the second electrical signal is generated when the pin tumbler assembly near the center of the keyhole is activated, the possibility of accidental activation is small, and the second threshold can be lower than the first threshold. For example, if more than two second electrical signals are detected within 3 seconds, a second alarm message is generated. This second alarm message can also be interpreted as a possible attempt by a criminal to open the lock. Furthermore, the second electrical signal can be combined with a third electrical signal to determine whether the homeowner is being coerced; the specific method is described below.

[0093] In one possible implementation, the electrical signal includes a door open / close status signal and a third electrical signal, and the method further includes the steps of:

[0094] S805: Determine the opening status of the smart door based on the door opening / closing status signal, which includes a door open signal or a door closed signal.

[0095] S806: Determine the target voltage based on the third electrical signal, which is generated when the fifth contact and the second contact in the detection circuit are connected;

[0096] S807: When the door opening / closing status signal is a door open signal and the target voltage does not meet the third threshold requirement, generate a third alarm message.

[0097] In one example, the third alarm message can be understood as: the door lock was opened without using a key that matches this smart door, meaning that there is a possibility that a criminal has successfully opened the door.

[0098] In one possible implementation, the method further includes the following steps:

[0099] S808: When the door opening / closing status signal is a door not open signal and the target voltage meets the third threshold requirement, generate key insertion information;

[0100] S809: Determine the number of times the second electrical signal is acquired within the third preset time length;

[0101] S810: If the number of times the second electrical signal is acquired exceeds the fourth threshold, a fourth alarm message is generated.

[0102] In one example, the fourth alarm message can be understood as: a key matching this smart door has been detected inserted into the lock, and after the key was initially inserted, it was partially pulled out and then reinserted, potentially indicating that a criminal may be coercing the homeowner to open the door. The number of times the key is pulled out and reinserted (the number of times the second electrical signal is triggered) can be preset by the homeowner.

[0103] In one possible implementation, the method further includes the following steps:

[0104] When the door opening / closing status signal is a door open signal and the target voltage meets the third threshold requirement, unlocking information is generated.

[0105] Unlock information can be used to record the time when a smart door is opened normally.

[0106] In one possible implementation, the method further includes the following steps:

[0107] The wireless communication module is controlled to send information, including at least one of alarm information, key insertion information, and unlocking information.

[0108] In one example, alarm information, key insertion information, and unlocking information can be sent to the cloud for storage via a wireless communication module. Alarm information can then be sent to the homeowner or emergency contact via the cloud.

[0109] It should be noted that smart doors may also include image acquisition devices to capture images of the environment outside the door and send the captured images to the homeowner or emergency contact via the cloud when any of the aforementioned alarm messages are generated. This assists the homeowner or emergency contact in viewing and identifying the actual situation through images.

[0110] Figure 8 This is a schematic flowchart illustrating the implementation of a smart door control method according to an embodiment of the present disclosure, as shown below. Figure 8 As shown, the control method for the smart door includes the following steps:

[0111] Step 1: Acquire electrical signals.

[0112] Step 2: In response to the first electrical signal, the processor is woken up, the processor starts timing, and proceeds to Step 3. When the timing is up, proceed to Step 4.

[0113] Step 3: Determine the target voltage of the third electrical signal and the door opening / closing status signal. Specifically, this includes: determining the opening state of the smart door based on the door opening / closing status signal, i.e., step S805 above; and determining the target voltage based on the third electrical signal, i.e., step S806 above.

[0114] If the door opening / closing status signal is "door open" and the target voltage meets the third threshold requirement, proceed to step five.

[0115] If the door opening / closing status signal is "door not open" and the target voltage meets the third threshold requirement, proceed to step six.

[0116] If the door opening / closing status signal is "door open" and the target voltage does not meet the third threshold requirement, proceed to step eight.

[0117] Step 4: Determine whether the number of times the first electrical signal is acquired within the time limit exceeds the first threshold, i.e., step S801 above. If it exceeds the threshold, proceed to step 8.

[0118] Step 5: Generate unlocking information.

[0119] Step Six: Generate key insertion information, i.e., step S808 above, start timing, and when the timing is up, proceed to step seven.

[0120] Step 7: Determine whether the number of times the second electrical signal is received exceeds the fourth threshold. Specifically, this includes determining the number of times the second electrical signal is received within the third preset time length, i.e., step S809 above. If it exceeds the threshold, proceed to step 8.

[0121] Step 8: Generate alarm information and activate the alarm. The generated alarm information corresponds to the above situations, specifically: if the number of times the first electrical signal is acquired exceeds the first threshold, generate the first alarm information, i.e., step S802 above. If the door opening / closing status signal is a door open signal and the target voltage does not meet the third threshold requirement, generate the third alarm information, i.e., step S807 above. If the number of times the second electrical signal is acquired exceeds the fourth threshold, generate the fourth alarm information, i.e., step S810 above.
