[0027] Figure 2 This is a circuit diagram of one embodiment of the intelligent control system for electric vehicle storage boxes provided by this utility model. Detailed Implementation

[0028] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this disclosure.

[0029] This utility model provides an intelligent control system for electric vehicle storage boxes, such as... Figure 1 As shown, it includes a signal module, a control module, a drive module, a power supply module, and a charging module, wherein...

[0030] The signal module is connected to the control module and is used to input control signals to the control module;

[0031] The storage box is equipped with an electronic lock. The control module is connected to the drive module, and the drive module is connected to the motor of the electronic lock. The drive module is used to drive the motor of the electronic lock according to the control signal, so that the storage box enters the open state or the closed state.

[0032] The power module is used to supply power to the control module and the drive module, and the charging module is used to charge the power module.

[0033] Specifically, the control signal is used to control the storage box to enter or close the open state. The electronic lock inside the storage box generally has a bolt and a keyhole. When the control signal controls the storage box to be in the closed state, the drive module drives the motor of the electronic lock according to the control signal. The motor rotates, causing the bolt to extend and insert into the keyhole to lock the electronic lock, thus keeping the storage box closed and unable to be opened. When the control signal controls the storage box to be in the open state, the drive module drives the motor of the electronic lock according to the control signal. The motor rotates, causing the bolt to retract and exit the keyhole to unlock the electronic lock, thus keeping the storage box openable. The specific forms of the signal module, control module, drive module, power module, and charging module can be found in the following description.

[0034] Furthermore, the input methods for the control signals may include button input, remote control via mobile APP, NFC card swiping, RF remote control, etc. Correspondingly, the signal module includes a button module, an IoT (Internet of Things) module, an NFC (Near Field Communication) module, and an RF (Radio Frequency) module. The IoT module, NFC module, and RF module can establish communication with the control module through common communication methods such as CAN, RS485, 433 communication, and Bluetooth. Users can input control signals to the control module via physical buttons, or via a mobile APP through the IoT module, or by bringing an NFC card close to the sensing area of ​​the NFC module, which then inputs a control signal to the control module, or by the user sending a signal from the transmitter of the RF module to the receiver of the RF module, which then inputs a control signal to the control module. The specific structures of the aforementioned IoT module, NFC module, and RF module, as well as the specific operating methods for sending control signals to the control unit using the IoT module, NFC module, and RF module, are consistent with existing technologies.

[0035] Figure 2The image shows a structural example of a button module. The control module includes a control unit, and the button module includes a capacitor C1, a button switch K1, and a resistor R1. One end of the button switch K1 is grounded, and the other end of the button switch K1 is connected to one end of the capacitor C1, one end of the resistor R1, and the fourth control pin (PA3) of the control unit. The other end of the resistor R1 is connected to a power supply voltage V. dd The other end of capacitor C1 is grounded. Resistor R1 is a pull-up resistor used to fix uncertain signals at a high level, and capacitor C1 is a filter capacitor used to eliminate jitter. When button switch K1 is pressed, the fourth control pin is at a low level, meaning the control unit inputs a control signal to open the storage box; conversely, when button switch K1 is open, the fourth control pin is at a high level, meaning the control unit inputs a control signal to close the storage box.

[0036] Furthermore, the driving module includes a driving chip and a diode D1. In this embodiment, the driving chip can be an L298N, and the control unit can be an STM32 series microcontroller. The first input pin (IN1) of the driving chip is connected to the first control pin (PA0) of the control unit, the second input pin (IN2) of the driving chip is connected to the second control pin (PA1) of the control unit, the first output pin (OUT1) of the driving chip is connected to the negative terminal of the diode D1 and the positive terminal of the electronic lock motor, the second output pin (OUT2) of the driving chip is connected to the positive terminal of the diode D1 and the negative terminal of the electronic lock motor, the ground pin (GND) of the driving chip is grounded, and the power supply pin (VCC) of the driving chip is connected to the power supply module. The control pin of the control unit is the input / output (GPIO) pin of the control unit. The diode D1 is a freewheeling diode because the DC motor inside the electronic lock is an inductive load (the current cannot change abruptly). When the motor stops, in addition to disconnecting the power supply, a freewheeling circuit needs to be formed to release the energy on the motor. Otherwise, the freewheeling current generated by the motor may damage the MOSFET in the driver chip. Therefore, diode D1 is used to construct the freewheeling circuit.

[0037] In this embodiment, when a low-level control signal is received at the fourth control pin (PA3) of the control unit, the first control pin (PA0) of the control unit outputs a high-level signal to the first input pin (IN1) of the driver chip, and at the same time, the second control pin (PA1) of the control unit outputs a low-level signal to the second input pin (IN2) of the driver chip. The driver chip outputs a high-level signal through the first output pin (OUT1) and a low-level signal through the second output pin (OUT2), causing the motor of the electronic lock to rotate forward, driving the bolt to retract and unlocking the electronic lock, thereby opening the storage box. When a high-level control signal is received at the fourth control pin (PA3) of the control unit, the first control pin (PA0) of the control unit outputs a low-level signal to the first input pin (IN1) of the driver chip, and at the same time, the second control pin (PA1) of the control unit outputs a high-level signal to the second input pin (IN2) of the driver chip. The driver chip outputs a low-level signal through the first output pin (OUT1) and a high-level signal through the second output pin (OUT2), causing the motor of the electronic lock to rotate in reverse, driving the bolt to extend and locking the electronic lock, thereby locking the storage box.

[0038] Furthermore, the intelligent control system for the electric vehicle storage box also includes an anti-theft alarm module. The anti-theft alarm module is connected to the control module and is used to send an alarm signal to the control module when the storage box vibrates. The control module controls the buzzer in the anti-theft alarm module to sound according to the alarm signal.

[0039] Specifically, the anti-theft alarm module includes a vibration sensor; the output pin (DO) of the vibration sensor is connected to the third control pin (PA2) of the control unit, the power supply pin (VCC) of the vibration sensor is connected to the power supply voltage VCC, and the ground pin (GND) of the vibration sensor is grounded. In this embodiment, the vibration sensor can be an SW-420 model. When the storage box is illegally pried or impacted, it will vibrate, and at this time, the vibration sensor will send an alarm signal to the control unit through its output pin.

[0040] Furthermore, the burglar alarm module also includes resistors R2 and R3, capacitors C2 and C3, and a switching transistor Q1, wherein...

[0041] One end of resistor R2 is connected to the fifth control pin (PA4) of the control unit, and the other end of resistor R2 is connected to one end of resistor R3 and the second electrode of switch Q1. The first electrode of switch Q1 and the other end of resistor R3 are grounded. Capacitor C2 is connected in parallel with resistor R3. The third electrode of switch Q1 is connected to the negative terminal of buzzer. The positive terminal of buzzer is connected to the power supply voltage VCC and grounded through capacitor C3.

[0042] In this embodiment, the switching transistor Q1 is an NPN transistor. For an NPN transistor, the first electrode is the emitter, the second electrode is the base, and the third electrode is the collector. In the burglar alarm module, the resistor R2 is a current-limiting resistor, used to prevent excessive current from burning out the transistor Q1 when the fifth control pin (PA4) outputs a high level. The resistor R3 is a pull-down resistor, used to fix uncertain signals at a low level, preventing the transistor Q1 from being mis-activated. Resistor R3 and capacitor C2 are used to effectively filter out interference signals in environments with strong interference, preventing the buzzer from changing its sound or emitting sound unexpectedly; capacitor C3 is a power supply filter capacitor, used to filter out high-frequency noise from the power supply.

[0043] When the vibration sensor detects vibration, it sends an alarm signal to the control unit. Upon receiving the alarm signal, the control unit outputs a high-level signal on its fifth control pin (PA4), thereby turning on transistor Q1 and causing the buzzer to sound, thus providing an alarm effect. Furthermore, after receiving the alarm signal, the control unit can also synchronize the alarm signal to the IoT module in the signal module. The IoT module then sends an alarm message to a mobile app, allowing users to remotely monitor the security status of the locker. The specific method by which the IoT module sends the alarm message to the mobile app is consistent with existing technology.

[0044] Furthermore, the power module includes a lithium battery, a voltage regulator chip, capacitor C4, and capacitor C5. The positive terminal of the lithium battery is connected to the power supply pin (VCC) of the driver chip and the input pin (VIN) of the voltage regulator chip, and the negative terminal of the lithium battery is grounded.

[0045] The input pin (VIN) of the voltage regulator chip is grounded through capacitor C4, and is also connected to the sampling pin (ADC) of the control unit. The output pin (OUT) of the voltage regulator chip is grounded through capacitor C5. Capacitors C4 and C5 are used for power input filtering, effectively purifying the power signal. The voltage output from the lithium battery is applied to the power pin of the driver chip to power the driver chip. The voltage regulator chip can be an AMS1117, used to convert the voltage output from the lithium battery into the power supply voltage required by the control unit to power the control unit.

[0046] Furthermore, the charging module includes a voltage converter chip (DCDC) and a resistor R4. The input pin of the voltage converter chip is connected to the power supply voltage VCC, the ground pin (GND) of the voltage converter chip is grounded, the output pin (OUT) of the voltage converter chip is connected to the input pin (VIN) of the voltage regulator chip, and the enable pin (ACC) of the voltage converter chip is connected to the sixth control pin (PA5) of the control unit through resistor R4. Resistor R4 is a current-limiting resistor used to prevent excessive current from burning out the voltage converter chip when the sixth control pin (PA5) of the control unit outputs a high level.

[0047] The control unit detects the output voltage of the lithium battery through the sampling pin (ADC). When the control unit detects that the output voltage of the lithium battery is lower than the set voltage value, it sends a high-level enable signal to the enable pin (ACC) of the voltage conversion chip through the sixth control pin (PA5) to control the voltage conversion chip to start charging the lithium battery. When the control unit detects that the output voltage of the lithium battery is higher than the set voltage value, it sends a low-level enable signal to the enable pin (ACC) of the voltage conversion chip, and the voltage conversion chip stops charging the lithium battery. The set voltage value can be set according to the actual situation.
