Description

Technical Field

[0001] This utility model relates to the field of electronic lock technology, and in particular to an electronic lock control circuit and an electronic lock control device. Background Technology

[0002] With the widespread adoption of electric vehicles, the construction of charging infrastructure is accelerating, and charging piles have become one of the core supporting equipment for the development of electric vehicles. Most existing charging piles are located outdoors, and operators also primarily use them in outdoor environments. Therefore, higher requirements are placed on the safety, stability, and adaptability of the system during the charging process. Especially in key areas such as charging interface connection, power supply control, and payment management, effective control and protection mechanisms are essential.

[0003] The relevant standards for "Electric Vehicle Conductive Charging Systems" clearly specify the locking control during the charging process, requiring charging piles to have reliable electronic lock control capabilities before, during, and after charging operations. Traditional electronic lock control methods often rely on the stability of external power supply. However, in practical applications, unexpected power outages, power failures, system malfunctions, and other situations may occur during charging, causing the electronic lock to fail to unlock properly. This can easily lead to problems such as plug jamming, users being unable to unplug the charging gun, and the charging pile failing to restart, affecting the continuity of the charging process and user safety, and even causing adverse consequences such as user confinement or vehicle restrictions.

[0004] To address the aforementioned issues, most electronic lock systems in related technologies introduce energy storage capacitors to achieve emergency unlocking. However, these systems suffer from technical defects such as inaccurate unlocking timing control, unstable power-down signal acquisition, and insufficient driving capability of the execution circuit, making it difficult to meet the reliability requirements in complex field environments.

[0005] Therefore, the relevant technologies need to be improved. Utility Model Content

[0006] The main objective of this invention is to provide an electronic lock control circuit and an electronic lock control device to at least solve the technical problems mentioned in the related art.

[0007] To achieve the above objectives, the first aspect of this utility model provides an electronic lock control circuit, which includes an energy storage circuit, a signal control circuit, a voltage comparison circuit, and an execution circuit. The input terminal of the energy storage circuit is electrically connected to the power supply, and the output terminal of the energy storage circuit is simultaneously electrically connected to the input terminal of the voltage comparison circuit and the power supply input terminal of the execution circuit. The first input terminal of the signal control circuit is used to electrically connect to an external processor, the first output terminal of the signal control circuit is electrically connected to the first control input terminal of the execution circuit, the output terminal of the voltage comparison circuit is electrically connected to the second control input terminal of the execution circuit, and the output terminal of the execution circuit is used to electrically connect to an electronic lock. When the electronic lock control circuit is in a power-off state, the energy storage circuit is used to transmit the energy storage voltage to the execution circuit and the voltage comparison circuit. The signal control circuit is used to receive the power-down unlock control signal transmitted by the processor and output a temporary unlock control signal to the execution circuit. The voltage comparison circuit is used to receive the energy storage voltage and output a high-level signal to the execution circuit. The execution circuit is used to receive the energy storage voltage, the high-level signal and the temporary unlock control signal, and output an unlock control signal for unlocking the electronic lock.

[0008] A second aspect of this utility model provides an electronic lock control device, including an electronic lock and an electronic lock control circuit as described in the first aspect, wherein the electronic lock control circuit is used to control the electronic lock to unlock or lock.

[0009] This invention discloses an electronic lock control circuit and device.

The signal control circuit receives the power-down unlocking control signal transmitted by the processor and outputs a temporary unlocking control signal to the execution circuit. The voltage comparison circuit receives the stored energy voltage and outputs a high-level signal to the execution circuit. The execution circuit receives the stored energy voltage, the high-level signal, and the temporary unlocking control signal, and outputs an unlocking control signal to unlock the electronic lock. In other words, this technical solution utilizes the stored energy voltage provided by the energy storage capacitor as an emergency power source in the system's power-off state. Combined with the voltage comparison circuit determining the power-off state, and the signal control circuit outputting a temporary unlocking signal to drive the execution circuit to unlock, this achieves automatic power-down unlocking. This effectively prevents the risk of the electronic lock failing to open due to sudden power outages, ensuring that users can smoothly unplug the charging gun in abnormal situations such as power failures. It improves system safety and reliability, and is particularly suitable for high-safety applications such as outdoor charging of electric vehicles. Attached Figure Description

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 of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0013] It should be noted that related terms such as "first" and "second" can be used to describe various components, but these terms do not limit the component. These terms are only used to distinguish one component from another. For example, without departing from the scope of this utility model, the first component can be referred to as the second component, and the second component can similarly be referred to as the first component. The term "and / or" refers to any one or more combinations of related and descriptive terms.

[0014] Please see Figure 1 This application provides an electronic lock control circuit for controlling the locking and unlocking of electronic locks in electric vehicle charging facilities such as charging piles, especially for automatically unlocking electronic locks in the event of a power failure, thereby improving the security and reliability of the system.

[0015] The electronic lock control circuit includes at least an energy storage circuit 10, a signal control circuit 20, a voltage comparison circuit 30, and an execution circuit 40. The components of each circuit are described below: The input terminal of the energy storage circuit 10 is electrically connected to an external power source (e.g., a charging pile power system) to store electrical energy in the energy storage capacitor C1 when the system is powered normally. The output terminal of the energy storage circuit 10 is also electrically connected to the input terminal of the voltage comparison circuit 30 and the power supply input terminal of the execution circuit 40, so that it can continue to work in the power-off state.

[0016] The first input terminal of the signal control circuit 20 is electrically connected to an external processor, and the first output terminal of the signal control circuit 20 is electrically connected to the first control input terminal of the execution circuit 40. The signal control circuit 20 receives control signals when the system is powered on normally and power-off unlocking control signals when the system is powered off. It outputs control signals to the execution circuit when the system is powered on, or outputs temporary unlocking control signals to the execution circuit when the system is powered off, thereby driving the electronic lock to perform locking or unlocking operations when powered on normally, or unlocking operations when powered off.

[0017] The output of the voltage comparison circuit 30 is electrically connected to the second control input of the execution circuit 40. After receiving the energy storage voltage transmitted by the energy storage circuit 10, the voltage comparison circuit 30 compares the energy storage voltage with the set reference voltage. When the energy storage voltage is lower than the reference voltage (indicating "power-down trigger"), it outputs a high-level signal (whose voltage value is close to the energy storage voltage, but not the energy storage voltage itself) based on the energy storage voltage to the execution circuit to trigger the electronic lock unlocking operation.

[0018] The power input terminal of the execution circuit 40 is connected to the energy storage circuit 10, the control input terminal is connected to the signal control circuit and the voltage comparison circuit respectively, and the output terminal is used to connect to the electronic lock. In the power-off state, the execution circuit receives the high-level signal output by the voltage comparison circuit 30, the energy storage voltage output by the energy storage circuit 10, and the temporary unlocking control signal output by the signal control circuit 20 (the control terminal receives a total of two signals), and uses the energy storage voltage transmitted from the energy storage circuit 10 (the power supply terminal receives one signal) to drive the electronic lock to complete the automatic unlocking operation.

[0019] Specifically, the working principle of the entire electronic lock control circuit in the power-off state is as follows: When the electronic lock control circuit is in a power-off state, the energy storage circuit 10 is used to transmit the energy storage voltage to the execution circuit 40 and the voltage comparison circuit 30. The signal control circuit 20 is used to receive the power-down unlock control signal transmitted by the processor and output a temporary unlock control signal to the execution circuit 40. The voltage comparison circuit 30 is used to receive the energy storage voltage and output a high-level signal to the execution circuit 40. The execution circuit 40 is used to receive the energy storage voltage, the high-level signal and the temporary unlock control signal, and output an unlock control signal for unlocking the electronic lock.

[0020] As can be seen, in the case of a power outage (i.e., when the external power supply is unavailable), the electronic lock control circuit of this application uses the energy storage voltage provided by the energy storage capacitor in the energy storage circuit as an emergency power source. Combined with the voltage comparison circuit, the power outage state is determined, and a temporary unlocking signal is output through the signal control circuit to drive the execution circuit to unlock, thereby realizing the automatic power-off unlocking function. This effectively prevents the risk of the electronic lock being unable to open due to a sudden power outage, ensuring that the user can smoothly unplug the charging gun in abnormal situations such as power outages. This improves the safety and reliability of the system and is particularly suitable for high-safety application scenarios such as outdoor charging of electric vehicles.

[0021] It should be noted that the electronic lock control circuit in this embodiment can also control the electronic lock to unlock or lock under normal power supply conditions. Specifically: when the electronic lock control circuit is under normal power supply conditions, the signal control circuit receives the conventional unlocking control signal or conventional locking control signal output by the processor and outputs the corresponding conventional control signal to the execution circuit. The voltage comparison circuit receives the power supply voltage and outputs a low-level signal to the execution circuit. The execution circuit receives the power supply voltage, the low-level signal, and the conventional control signal, and outputs a control signal for unlocking or locking the electronic lock.

[0022] It should also be understood that the protection scope of this application embodiment mainly refers to the connection relationship of each circuit in the electronic lock control circuit. After the above connection relationship is established, the corresponding signal transmission function, control logic, and automatic unlocking function triggered in the power-off state can all be implemented by the circuit structure itself, without relying on additional complex control logic.

[0023] Please see Figure 2 The energy storage circuit 10 is equipped with an energy storage capacitor C1, which is used to store energy based on the external power supply voltage under normal power supply conditions, and to supply the energy storage voltage to the voltage comparison circuit 30 and the execution circuit 40 under power failure conditions so that they can continue to work under power failure conditions.

[0024] Specifically, when the electronic lock control circuit is in a power-off state, the energy storage capacitor C1 releases its stored charge to form an energy storage voltage. The energy storage circuit provides operating voltage to the voltage comparison circuit and the execution circuit based on the voltage maintained by the capacitor, thereby ensuring that the electronic lock control system still has the most basic control and drive capabilities during power failure, and thus realizes the emergency unlocking function of the electronic lock.

[0025] In addition, the energy storage circuit 10 is also equipped with a first diode D1 and a first resistor R1. The anode of the first diode D1 is electrically connected to the positive terminal of the external power supply, the cathode is electrically connected to the first end of the first resistor R1, the second end of the first resistor R1 is electrically connected to the first end of the energy storage capacitor C1, and the other end of the energy storage capacitor C1 is electrically connected to the negative terminal of the power supply. This structure enables the power supply to charge the energy storage capacitor under normal power supply conditions, while preventing the energy storage voltage from flowing back to the power supply side through the unidirectional conduction of the first diode when the power is off. The first resistor is used for current limiting protection, thereby improving system stability and energy storage safety.

[0026] In an optional embodiment of this application, the energy storage circuit is further configured with a second resistor R2.

[0027] Specifically, the first terminal of the second resistor R2 is electrically connected to both the anode of the first diode D1 and the positive terminal of the power supply, while the second terminal is grounded. This second resistor R2 acts as a dummy load resistor, used to rapidly discharge the energy storage capacitor C1 after power failure, thereby improving the stability of the energy storage voltage, preventing misjudgments in subsequent control logic due to prolonged residual voltage in the capacitor, and enhancing the system's responsiveness and safety.

[0028] Please see Figure 3 The signal control circuit 20 is also equipped with a third resistor R3, a fourth resistor R4, a fifth resistor R5, and a sixth resistor R6.

[0029] Specifically, the first terminal of the third resistor R3 is electrically connected to an external processor to receive a temporary locking control signal. The second terminal of the third resistor R3 is electrically connected to the first terminal of the fourth resistor R4, and the second terminal of the fourth resistor R4 is grounded. The first terminal of the fifth resistor R5 is also electrically connected to an external processor to receive a regular unlocking control signal (i.e., Figure 3 The processor control signal (issued by the processor when the power is on) or the power-off unlock control signal (issued by the processor when the power is off) is connected to the first terminal of the sixth resistor R6, and the second terminal of the sixth resistor R6 is grounded.

[0030] Among them, the second end of the fifth resistor R5 and the first end of the sixth resistor R6 constitute the first output terminal of the signal control circuit 20. Figure 3 The first output terminal (marked as output 1) is connected to the first control input terminal of the execution circuit for outputting an unlock control signal; and the second terminal of the third resistor R3 and the first terminal of the fourth resistor R4 constitute the second output terminal of the signal control circuit 20. Figure 3 The output (marked as output 2) is also connected to the first control input of the execution circuit and is used to output the locking control signal.

[0031] This embodiment uses the third resistor R3, the fourth resistor R4, the fifth resistor R5, and the sixth resistor R6 to form separate output paths for unlocking and locking signals during normal power supply, as well as an unlocking signal output during power failure. Based on the formed resistor network, current limiting, debouncing, and logic isolation of the control signal are achieved, ensuring that the execution circuit receives clear and effective control commands.

[0032] Please continue reading. Figure 3 The signal control circuit is also equipped with a second diode D2 and a third diode D3.

[0033] Specifically, the cathode of the second diode D2 is electrically connected to the first terminal of the fifth resistor R5, and the anode is used for electrical connection with the processor and to receive the conventional unlock control signal (i.e., Figure 3 The processor control signal (issued by the processor during normal power supply) or the power-down unlock control signal (issued by the processor during power-down). Additionally, the cathode of the third diode D3 is also electrically connected to the first terminal of the fifth resistor R5, and its anode is also used for electrical connection to the processor and to receive another normal unlock control signal or power-down unlock control signal.

[0034] This implementation uses a parallel OR logic structure formed by the second diode D2 and the third diode D3 to effectively integrate multiple unlocking-related signals. When any input signal is high, the level can be transmitted to the fifth resistor R5 to drive the control signal of the execution circuit. This structure avoids mutual interference between multiple control signals (it can output corresponding control signals to the execution circuit under normal power supply or power failure conditions), and still has unlocking response capability under power failure or control abnormality conditions, enhancing the reliability and fault tolerance of the system.

[0035] Please see Figure 4 The voltage comparison circuit 30 is equipped with comparator U1, seventh resistor R7, eighth resistor R8, fourth diode D4, fifth diode D5, sixth diode D6 and seventh diode D7.

[0036] Specifically, the power supply terminal of comparator U1 is electrically connected to the cathodes of both the fourth diode D4 and the fifth diode D5. The anode of the fourth diode D4 is connected to the positive terminal of the power supply, and the anode of the fifth diode D5 is used to receive the energy storage voltage to ensure that the comparator can still be supplied with power when the power is off. The non-inverting input terminal of comparator U1 is electrically connected to the cathodes of both the sixth diode D6 and the seventh diode D7 to receive the reference voltage signal generated by the resistor divider. The inverting input terminal of the comparator is electrically connected to the first terminals of the seventh resistor R7 and the eighth resistor R8, respectively. The second terminal of the seventh resistor R7 is electrically connected to the energy storage voltage, and the second terminal of the eighth resistor R8 is grounded. The anodes of the sixth diode D6 and the seventh diode D7 are also electrically connected to the energy storage voltage, and the ground terminal of comparator U1 is grounded.

[0037] This embodiment establishes a stable reference voltage and compared voltage path through the seventh resistor R7, the eighth resistor R8, the fourth diode D4, and the fifth diode D5, and achieves voltage direction control and reverse current prevention through the sixth diode D6 and the seventh diode D7. Therefore, when the electronic lock control circuit is powered off, if the received energy storage voltage is lower than the set reference voltage value, the comparator outputs a high-level signal to the execution circuit, thereby triggering the unlocking control process in the power-off state.

[0038] Please see Figure 5 The execution circuit 40 includes an H-bridge circuit.

[0039] Specifically, the power input terminal of the H-bridge circuit is used to receive the energy storage voltage output by the energy storage circuit 10 based on the energy storage capacitor C1, the first control input terminal of the H-bridge circuit is used to be electrically connected to the first output terminal or the second output terminal of the signal control circuit, and the second control input terminal of the H-bridge circuit is used to be electrically connected to the output terminal of the voltage comparison circuit. When the electronic lock control circuit is in a power-off state, the H-bridge circuit is used to receive the stored energy voltage ( Figure 5 Input power supply), temporary unlock control signal ( Figure 5 The first input signal in the signal) and the high-level signal ( Figure 5 The second input signal in the circuit), the output of the H-bridge circuit is used to output the unlocking control signal for unlocking the electronic lock ( Figure 5 (The output signal in the circuit). Thus, the execution circuit 40, through the bidirectional driving capability of the H-bridge circuit, ensures that the electronic lock can still be unlocked normally in an emergency state of power interruption, enhancing the security and practicality of the system.

[0040] This application also provides an electronic lock control device including an electronic lock and an electronic lock control circuit as described in the above embodiments. The electronic lock control circuit is used to control the electronic lock to unlock or lock.

[0041] The electronic lock control circuit and device of this application embodiment, on the one hand, can use the energy storage voltage provided by the energy storage capacitor as an emergency power source when the system is powered off. Combined with the voltage comparison circuit to determine the power failure state, and output a temporary unlocking signal through the signal control circuit to drive the execution circuit to unlock, thereby realizing the automatic power-off unlocking function. This effectively prevents the risk that the electronic lock cannot be opened due to sudden power failure, and ensures that the user can smoothly unplug the charging gun in abnormal situations such as power failure. It improves the safety and reliability of the system and is particularly suitable for application scenarios that require high safety, such as outdoor charging of electric vehicles.

[0042] On the other hand, the electronic lock can be locked and unlocked under normal power supply conditions. This electronic lock control circuit can be controlled by an external processor via a signal control circuit to achieve the locking and unlocking operations. In this case, the processor can transmit locking or unlocking control signals to the signal control circuit based on the charging status or user instructions. The signal control circuit then outputs a corresponding control level to the execution circuit based on the received control signal, driving the execution circuit to output a control signal to the electronic lock, thereby completing the locking or unlocking operation. This control path operates under normal power supply conditions and has advantages such as fast response and high control accuracy, ensuring that the system has complete locking control capabilities during normal operation.

[0043] The specific embodiments of the utility model have been described in detail above, but they are only examples, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions to the utility model are also within the scope of the utility model. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of the utility model should be covered within the scope of the utility model.
