[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0031] The following is combined with Figures 1 to 6 This application describes a lock pick, a passive electronic lock assembly, an electronic lock, and a power transmitter.

[0032] According to the embodiments of the first aspect of this application, such as Figure 1 and Figure 2 As shown, the unlocking device includes a transmission component 2 and a connecting coil 21. The transmission component 2 has a first end and a second end. The first end is used to connect to the mobile terminal 3, and the connecting coil 21 is connected to the second end. The connecting coil 21 is used to nest and cooperate with the receiving coil 12 of the electronic lock 1, so that the unlocking device can transmit the energy of the mobile terminal 3 to the driving module 11 of the electronic lock 1, so that the driving module 11 can drive the electronic lock 1 to switch between the locked state and the unlocked state.

[0033] According to the unlocking device of this application embodiment, the cooperation between the connecting coil 21 of the transmission component 2 and the receiving coil 12 of the electronic lock 1 allows the energy of the mobile terminal 3 to be transmitted to the electronic lock 1 through the transmission component 2. Since the connecting coil 21 and the receiving coil 12 are nested, the energy transmission efficiency between them is effectively improved. This ensures that the electrical energy transmitted from the mobile terminal 3 to the electronic lock 1 through the transmission component 2 can directly drive the drive module 11, enabling the electronic lock 1 to switch between locked and unlocked states. In other words, this application, through the nested connection coil 21 and receiving coil 12, directly transmits the energy of the mobile terminal 3 to the electronic lock 1, achieving direct control of the opening and closing of the electronic lock 1. This eliminates the need for energy storage capacitors, MCUs, and other components within the electronic lock 1, simplifying the structure of the passive electronic lock 1 assembly, reducing its size, and lowering costs.

[0034] In related technologies, a large capacitor is also provided at the electronic lock 1 to store electrical energy. When the large capacitor stores enough electrical energy, it drives the motor. However, the large capacitor requires a lot of space, and since it is necessary to calculate the power consumption, an MCU is also required. The inclusion of the MCU and the large capacitor results in a large size and high cost for the electronic lock. In this application, the power of the mobile terminal 3 is directly transmitted to the drive module 11 through the transmission device 2. This allows the drive module 11 to directly drive the electronic lock 1 to switch between the locked and unlocked states, thus eliminating the need for an additional large capacitor and MCU at the electronic lock 1. This effectively simplifies the structure of the electronic lock 1, reduces its size, and lowers its cost.

[0035] For example, the mobile terminal 3 may be a mobile phone, a handheld tablet, or any other suitable mobile terminal 3, and this application embodiment does not limit it.

[0036] In some examples, the drive module 11 includes a motor 112, the motor shaft of which is connected to the latch drive rod of the electronic lock 1. The motor 112 can drive the latch drive rod to rotate clockwise or counterclockwise, causing the latch to move accordingly, thereby enabling the electronic lock 1 to switch directly between the locked and unlocked states.

[0037] In some cases, the transmitter 2 is connected to the mobile terminal 3 via a USB interface.

[0038] In some examples, authentication is primarily performed via mobile terminals and the cloud when controlling the switching of electronic lock states.

[0039] The following is an example illustrating the application of this application: A user triggers an unlock command via a mobile terminal 3 APP. The power management unit of the mobile terminal 3 is activated, outputting DC power to the transmission device 2. The electrical energy output by the transmission device 2 is directly connected to the input terminal of the motor 112 of the drive module 11, without the need for intermediate energy storage components. The encryption control unit of the mobile terminal 3 generates encrypted control commands (such as AES-128 encrypted PWM waveforms) and transmits them to the electronic lock 1 via the transmission device 2. The NFC 111 chip of the electronic lock 1 decrypts the commands and verifies their validity. If the verification is successful, it sends a forward / reverse signal to the drive module 11. The motor 112 of the drive module 11 rotates forward or reverse according to the direction of the received current. The torque of the motor 112 is amplified through a gear transmission mechanism, driving the latch of the electronic lock 1 to extend or retract, thus unlocking or locking. In other words, the encrypted control unit of the mobile terminal 3 directly generates the motor 112 drive signal (such as a PWM wave with adjustable duty cycle), which is transmitted to the electronic lock 1 through the transmission device 2, replacing the instruction parsing function of the traditional MCU inside the lock. Then, through the direct power supply architecture of the transmission device 2, combined with the centralized control of the mobile terminal 3, the electronic lock 1 can be miniaturized, reduced in cost, and operated with high reliability without the need for the energy storage capacitor and the MCU inside the lock.

[0040] In one embodiment of this application, such as Figure 2 The first end of the transmission component 2 is connected to the mobile terminal 3, and the second end of the transmission component 2 forms a connecting coil 21. The electronic lock 1 has a receiving coil 12. The connecting coil 21 and the receiving coil 12 are arranged opposite to each other, and the drive module 11 is electrically connected to the receiving coil 12.

[0041] It is understandable that when the mobile terminal 3 is connected to the first end of the transmission component 2, the electrical energy of the mobile terminal 3 can be transmitted to the transmission component 2, and then transmitted to the receiving coil 12 of the electronic lock 1 via the connecting coil 21 of the transmission component 2, thus realizing the transmission of electrical energy from the mobile terminal 3 to the electronic lock 1. The drive module 11 is electrically connected to the receiving coil 12, allowing the receiving coil 12 to directly transmit the received electrical energy to the drive module 11. This enables the drive module 11 to drive the electronic lock 1 to switch between locked and unlocked states, eliminating the need for energy storage capacitors, MCUs, and other components within the electronic lock 1. This simplifies the structure of the passive electronic lock assembly, reduces its size, and lowers costs.

[0042] For example, the connection coil 21 and the receiving coil 12 are arranged opposite to each other, which can mean that the connection coil 21 and the receiving coil 12 are spaced apart and arranged opposite to each other, or it can mean that the connection coil 21 and the receiving coil 12 are in contact with each other and arranged opposite to each other.

[0043] In some examples, the receiving coil 12 is integrally formed with the electronic lock 1, and the output end of the receiving coil 12 is directly connected to the power interface of the motor 112 of the drive module 11, without any rectifier / energy storage components in between.

[0044] In some examples, an annular magnetic shield is placed around the connecting coil 21 to reduce edge magnetic field leakage.

[0045] In some examples, the receiving coil 12 employs a differential winding structure to offset the changes in mutual inductance caused by positional offset.

[0046] In some cases, an NTC temperature sensor is embedded in the transmission element 2 to monitor the coil temperature rise in real time.

[0047] In one embodiment of this application, such as Figure 2 Both the connecting coil 21 and the receiving coil 12 are cylindrical structures, such that at least two surfaces of the connecting coil 21 are positioned opposite to the receiving coil 12.

[0048] It is understandable that by designing both the connecting coil 21 and the receiving coil 12 as cylindrical structures, with at least two surfaces of the connecting coil 21 facing the receiving coil 12, at least two surfaces of the connecting coil 21 can transmit electrical energy to the receiving coil 12, ensuring efficient energy transmission. This ensures that the electrical energy transmitted from the mobile terminal 3 to the drive module 11 via the transmission component 2 can power the drive module 11. In other words, this embodiment, through the multi-faceted (at least two-faced) coupling design of the cylindrical coil, improves the energy transmission efficiency to a level that can directly power the drive module 11. This eliminates the need for the energy storage capacitor and MCU within the lock body, reducing the size of the electronic lock 1 and lowering costs. It also improves response speed and eliminates the delay caused by capacitor charging in related technologies.

[0049] For example, the columnar structure refers to a hollow columnar structure, that is, the connecting coil 21 and the receiving coil 12 are hollow columnar structures, and the connecting coil 21 and the receiving coil 12 are arranged in a spiral.

[0050] Specifically, the connecting coil 21 is sleeved outside the receiving coil 12.

[0051] It is understandable that by placing the connecting coil 21 on the outside of the receiving coil 12, the relative area of ​​the connecting coil 21 and the receiving coil 12 is ensured, which can improve the energy transmission efficiency between the connecting coil 21 and the transmitting coil and reduce the loss when the energy emitted by the mobile terminal 3 is transmitted to the driving module 11.

[0052] Specifically, the receiving coil 12 is mounted outside the connecting coil 21.

[0053] It is understandable that by placing the receiving coil 12 on the outside of the connecting coil 21, the relative area of ​​the connecting coil 21 and the receiving coil 12 is ensured, which can improve the energy transmission efficiency between the connecting coil 21 and the transmitting coil and reduce the loss when the energy emitted by the mobile terminal 3 is transmitted to the driving module 11.

[0054] In one embodiment of this application, the transmission device 2 includes a USB interface, a communication chip, and an NFC chip connected in sequence. The USB interface is used to connect to the mobile terminal 3, and the NFC chip is connected to the connection coil 21.

[0055] It is understandable that the USB interface enables the connection between the transmitter 2 and the mobile terminal 3. The communication chip allows the transmitter 2 to communicate with external devices. The NFC chip allows control of the connection coil 21.

[0056] For example, the first end of the transmitter 2 is formed with a USB interface, and the second end of the transmitter 2 is a connection part connected between the NFC chip and the connection coil. The connection part can be a wire or an FPC.

[0057] According to an embodiment of the second aspect of this application, such as Figure 1 and Figure 2 As shown, the passive electronic lock assembly includes an electronic lock and the aforementioned unlocking device.

[0058] According to the passive electronic lock assembly of this application embodiment, the cooperation between the connecting coil 21 of the transmission element 2 and the receiving coil 12 of the electronic lock 1 allows the energy of the mobile terminal 3 to be transmitted to the electronic lock 1 through the transmission element 2. Since the connecting coil 21 and the receiving coil 12 are nested, the energy transmission efficiency between them is effectively improved. This ensures that the electrical energy transmitted from the mobile terminal 3 to the electronic lock 1 through the transmission element 2 can directly drive the drive module 11, enabling the electronic lock 1 to switch between locked and unlocked states. In other words, this application, through the nested connection coil 21 and receiving coil 12, directly transmits the energy of the mobile terminal 3 to the electronic lock 1, achieving direct control of the opening and closing of the electronic lock 1. This eliminates the need for energy storage capacitors, MCUs, and other components within the electronic lock 1, simplifying the structure of the passive electronic lock 1 assembly, reducing its size, and lowering costs.

[0059] In some embodiments, the first end of the transmitter 2 is detachably connected to the mobile terminal 3.

[0060] It is understandable that by connecting the first end of the transmission component 2 and the mobile terminal 3 in a detachable manner, the ease of assembly and disassembly between the transmission component 2 and the mobile terminal 3 is ensured. When the mobile terminal 3 is not required to transmit energy to the electronic lock 1, the transmission component 2 and the mobile terminal 3 can be separated. When the mobile terminal 3 is required to transmit energy to the electronic lock 1, the transmission component 2 and the mobile terminal 3 can be connected together.

[0061] In some embodiments, the second end of the transmission element 2 is detachably connected to the drive module 11.

[0062] It is understandable that by connecting the second end of the transmission component 2 and the drive module 11 in a detachable manner, the ease of assembly and disassembly between the transmission component 2 and the electronic lock 1 is ensured. When it is not necessary for the mobile terminal 3 to transmit energy to the electronic lock 1, the transmission component 2 and the drive module 11 can be separated. When it is necessary for the mobile terminal 3 to transmit energy to the electronic lock 1, the transmission component 2 and the drive module 11 can be connected together.

[0063] In some embodiments, the electronic lock 1 includes a drive module 11. The mobile terminal 3 transmits control signals and energy signals to the drive module 11 through a lock unlocker, so that the drive module 11 can switch the state of the electronic lock 1 according to the control signals.

[0064] It is understandable that the mobile terminal 3 can also transmit control signals to the drive module 11 through the unlocker to control the operation of the drive module 11, enabling the drive module 11 to perform corresponding operations according to the control signals and control the state switching of the electronic lock 1. In other words, the transmission component 2 can not only transmit the energy of the mobile terminal 3 to the drive module 11, but also transmit the control signals of the mobile terminal 3 to the drive module 11 to control the drive module 11. This eliminates the need for an energy storage element to drive the drive module 11 at the electronic lock 1, and also eliminates the need for an MCU to control the drive module 11 at the electronic lock 1. This simplifies the structure of the passive electronic lock assembly, reduces its size, and lowers the cost.

[0065] For example, when it is necessary to unlock the electronic lock 1, the mobile terminal 3 can transmit a first control command to the drive module 11 via the transmission device 2. After receiving the first control command, the drive module 11 starts working and drives the bolt of the electronic lock 1 to rotate, thus unlocking the electronic lock 1. When it is necessary to lock the electronic lock 1, the mobile terminal 3 can transmit a second control command to the drive module 11 via the transmission device 2. After receiving the second control command, the drive module 11 starts working and drives the bolt of the electronic lock 1 to rotate, thus locking the electronic lock 1.

[0066] In some embodiments, such as Figure 3 The drive module 11 includes an NFC circuit 111, a motor 112, and a rectifier circuit.

[0067] Specifically, the rectifier circuit is connected between the motor 112 and the receiving coil 12, and the rectifier circuit is used to supply power to the motor 112.

[0068] It is understandable that after receiving electrical energy, the receiving coil 12 transmits it to the rectifier circuit, which rectifies the current and then supplies power to the motor 112, thus achieving direct power supply to the motor 112 without the need for energy storage components such as capacitors.

[0069] Specifically, the NFC circuit 111 communicates with the mobile terminal 3 through the transmission device 2 to transmit control signals, and controls the operation of the motor 112 according to the control signals sent by the mobile terminal 3.

[0070] It is understandable that the transmission device 2 can transmit the control signal of the mobile terminal 3 to the NFC circuit 111. After receiving the control signal, the NFC circuit 111 can send a corresponding signal to the motor 112 to control the operation of the motor 112.

[0071] For example, the NFC circuit 111 can also communicate with the mobile terminal 3 via the transmission element 2 to transmit energy signals. That is, the transmission element 2 can transmit energy from the mobile terminal 3 to the NFC circuit 111, enabling the NFC circuit 111 to work normally. At the same time, the NFC circuit 111 can transmit energy to the motor 112, enabling the motor 112 to work normally. Thus, through the operation of the motor 112, the electronic lock 1 can switch between the locked and unlocked states.

[0072] In some examples, the mobile terminal 3 can transmit authentication information to the NFC circuit 111 via the transmission device 2. The NFC circuit 111 decodes the authentication information and confirms its correctness. When it is confirmed to be correct, the NFC circuit 111 then controls the operation of the motor 112 according to the control signal of the mobile terminal 3.

[0073] It should be noted that the motor 112 is directly or indirectly connected to the bolt of the electronic lock 1 to drive the bolt to move. In other words, the forward and reverse rotation of the motor 112 can drive the bolt to move in different directions, so that the electronic lock 1 can switch between the locked and unlocked states.

[0074] In some embodiments, such as Figure 4 The passive electronic lock assembly also includes a first switch module 4, which is located on the unlocker and is used to switch the unlocker between an open state and an open state.

[0075] It is understandable that when the first switch module 4 is in the open state, the transmission component 2 is also in the open state; when the first switch module 4 is in the closed state, the transmission component 2 is in the connected state. In other words, by switching the first switch module 4 on and off, the transmission component 2 can be switched between the open and connected states, thereby controlling the connection between the mobile terminal 3 and the drive module 11. For example, when the mobile terminal 3 and the electronic lock 1 are mismatched, the first switch module 4 can be in the open state, preventing the mobile terminal 3 from transmitting energy and signals to the drive module 11 via the transmission component 2, thus ensuring security.

[0076] In some examples, the first switch module 4 can be an electrically controlled switching element, such as a MOS transistor. The first switch module 4 can also be a user-controlled switching element, such as a push-button switch.

[0077] In some embodiments, such as Figure 5 The passive electronic lock assembly also includes a second switch module 5, which is connected between the drive module 11 and the unlocker.

[0078] It is understandable that by switching the second switch module 5 on and off, the connection between the drive module 11 and the transmission component 2 can be controlled, thereby realizing the connection and disconnection control between the transmission component 2 and the drive module 11.

[0079] In some examples, the second switch module 5 can be an electrically controlled switching element, such as a MOSFET. The second switch module 5 can also be a user-controlled switching element, such as a push-button switch.

[0080] According to the embodiments of the third aspect of this application, such as Figure 6 As shown, the electronic lock 1 includes an electronic lock body and a drive module 11. The drive module 11 is installed on the electronic lock body. The drive module 11 is used to communicate with the mobile terminal 3 and transmit energy through the unlocker so that the electronic lock 1 can switch between the locked state and the unlocked state. The drive module 11 includes a receiving coil 12, which is nested and cooperates with the connection coil 21 of the unlocker.

[0081] According to the embodiment of this application, the connection coil 21 and the receiving coil 12 of the unlocking device cooperate to allow the energy of the mobile terminal 3 to be transmitted to the electronic lock 1 through the unlocking device. Since the connection coil 21 and the receiving coil 12 are nested, the energy transmission efficiency between them is effectively improved. This ensures that the electrical energy transmitted from the mobile terminal 3 to the electronic lock 1 through the unlocking device can directly drive the drive module 11, enabling the electronic lock 1 to switch between locked and unlocked states. In other words, this application, through the nested connection coil 21 and the receiving coil 12, directly transmits the energy of the mobile terminal 3 to the electronic lock 1, achieving direct control of the opening and closing of the electronic lock 1. This eliminates the need for energy storage capacitors, MCUs, and other components within the electronic lock 1, simplifying the structure of the passive electronic lock 1 assembly, reducing its size, and lowering costs.

[0082] According to an embodiment of the fourth aspect of this application, the energy transmitter includes a connection interface, a communication chip, an NFC chip, and a connection coil 21 connected in sequence. The connection interface is used for physical connection / plugging with a first external device, and the connection coil 21 is used for nesting and cooperating with the receiving coil 12 of a second external device to transmit energy from the first external device to the second external device.

[0083] According to the embodiments of this application, the energy transmitter can connect to a first external device via a connection interface. A communication chip enables the energy transmitter to communicate with external devices. An NFC chip allows control of the connection coil 21. Since the connection coil 21 and the receiving coil 12 are nested together, the energy transmission efficiency between them is effectively improved, allowing energy from the first external device to be transmitted to the second external device more efficiently.

[0084] For example, the first external device is a mobile phone, tablet, or any other suitable device. The second external device is an electronic lock, a mobile phone, or any other suitable device.

[0085] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
