Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0019] Currently, during long-term operation, existing vehicles often experience problems such as excessively high temperatures and severe dust accumulation inside the onboard control box due to heat generated by electrical components and the effects of material dust. This can lead to increased equipment failure rates and decreased operational stability. However, most existing solutions for dust and high temperatures rely on manual dust removal and conventional air cooling methods, which may result in high error rates and unstable performance, making them unsuitable for various application scenarios.

[0020] Therefore, to address the aforementioned problems, this disclosure provides an on-board control box device that, through the coordinated control of multiple modules including liquid cooling, pressure dust prevention, and automated dust removal, can achieve efficient cooling and dust removal without system shutdown. It effectively solves the problem of high equipment failure rates caused by overheating and dust accumulation within the on-board control box. The liquid cooling module improves heat dissipation efficiency, the pressure dust prevention design reduces dust accumulation, and the automated dust removal mechanism avoids the risk of production interruptions caused by manual operation, reducing the failure rate, improving performance stability, and adapting to various application scenarios.

[0021] First, this disclosure provides an on-board control box device. Please refer to... Figure 1 , Figure 1 This is a structural block diagram of an on-board control box device provided in an embodiment of this disclosure. Figure 1 As shown, the device includes: The liquid cooling module 101 is located on the outside of the heat-generating element inside the vehicle control box, and is used to absorb heat and dissipate it based on the first command of the control module. Dustproof module 101 is used to draw in air and prevent dust from entering, based on a second command from the control module; The dust removal module 103 is located at the top and bottom of the vehicle control box and is used to blow or adsorb dust based on the third command of the control module. The control module 104 is used to send at least one of the following commands based on the status data of the vehicle control box: a first command, a second command, and a third command.

[0022] In this disclosure, the liquid cooling module can be understood as an active heat dissipation component with a high thermal conductivity liquid cooling medium (such as a special coolant, water-glycol solution, or at least one) as its core. It can adhere to the outer surface of heat-generating components (such as chips, power modules, etc.) inside the vehicle control box. Upon receiving the first command from the control module, it absorbs the heat generated by the components through the circulation of the medium (driven by an internal pump), and transfers the heat to the outside of the box through structures such as heat sinks and heat exchangers. This ultimately achieves precise and efficient cooling of the heat-generating components, preventing performance degradation or damage due to high temperatures.

[0023] In this disclosure, the dustproof module can be understood as a controlled filtration component integrated into the air intake channel of the vehicle control box. It typically includes a high-density dustproof filter (such as a high-efficiency particulate air (HEPA) filter, metal mesh, etc.) and an air damper control structure. Upon receiving a second command from the control module, the air damper opens and allows outside air to enter the box (meeting heat dissipation and ventilation requirements). At the same time, the filter physically blocks dust, sand, lint, and other impurities in the air from entering the core area of ​​the box, preventing impurities from adhering to the circuit board and component surfaces, and avoiding faults such as short circuits and poor contact.

[0024] In this disclosure, the dust removal module can be understood as an active cleaning component installed on the top and bottom of the vehicle control box (covering key dust accumulation areas inside the box). After receiving a third command from the control module, it can adopt either a blowing or adsorption mode: if the blowing mode is adopted, compressed air can be blown onto the surface of components, filters, and other easily dust-accumulating parts through the built-in high-pressure air nozzle to blow away dust; if the adsorption mode is adopted, dust scattered inside the box can be collected into a dedicated dust box to maintain a clean environment inside the box.

[0025] In this disclosure, the control module can be understood as the decision-making and control core of the vehicle-mounted control box device. It first collects status data in real time through various sensors deployed within the box (such as temperature sensors, dust concentration sensors, component operating status sensors, etc.); then analyzes and judges the data; finally, based on the judgment results, it sends corresponding control commands (first, second, and third commands) to at least one of the liquid cooling module, dustproof module, and dust removal module to achieve coordinated operation of each module and ensure that the control box is always in a stable and reliable operating state.

[0026] The cooling module disclosed herein will be described in detail below, including: A cooling plate, located on the outside of the heating element, is used to absorb the heat from the heating element and transfer it to the liquid cooling channel; A circulating pump, located on one side of the cooling plate, is used to control the flow of coolant and / or the magnitude of coolant flow rate in the liquid cooling channel based on a first command. A radiator is used to dissipate the heat carried by the coolant to the outside of the vehicle's control box; A temperature sensor is used to measure the initial temperature inside the vehicle control box and send the initial temperature to the control unit.

[0027] Specifically, the cooling plate can be a plate-shaped structure made of a high thermal conductivity material (such as oxygen-free copper, aluminum alloy, or graphite composite material). Its inner side can be tightly bonded to the heat-generating element (such as a CPU, power transistor, etc.) using at least one of the following: thermally conductive silicone grease or phase change material. The outer side or inner side integrates sealed liquid cooling channels (such as microchannels, serpentine channels, etc.). During operation, the cooling plate can quickly absorb heat from the surface of the heat-generating element and transfer the heat to the coolant flowing through the liquid cooling channels, achieving efficient heat transfer from the heat source to the cooling medium. For example, the cooling plate can have embedded micro-liquid cooling channels and be made of aluminum alloy (thermal conductivity ≥200 W / m·K).

[0028] The circulating pump is the power core of the liquid cooling circulation system, typically a miniature DC pump or a variable frequency pump. Upon receiving the first command from the control module, it controls the flow of coolant within the closed-loop channel formed by the cooling plate, radiator, and connecting pipes by adjusting the motor speed. When the temperature of the heat-generating elements is high, the pump can increase its speed to increase the coolant flow rate and accelerate heat removal; when the temperature is low, it can decrease its speed to reduce the flow rate and save energy, thus dynamically matching the heat dissipation requirements. For example, the circulating pump can control the flow rate within the range of 0.5-2 L / min.

[0029] The radiator is a component that dissipates heat to the outside. It typically consists of dense cooling fins (to increase the heat dissipation area) and built-in heat exchange pipes, and is usually installed in the ventilation openings or on the outside of the vehicle's control box. The heat carried by the coolant is transferred to the cooling fins through the heat exchange pipes, and then dissipated to the external environment of the control box through natural convection (airflow outside the box) or forced air cooling (with a cooling fan), thus completing the final release of heat.

[0030] Temperature sensors are the sensing elements of the cooling module, typically at least one of the following: thermocouple, thermistor, or digital temperature chip. They can be installed in high-temperature sensitive areas within the control box. They can measure the initial temperature at their location (i.e., the real-time temperature of the heating element or key areas within the box) in real time and with high precision, and convert the temperature signal (analog or digital signal) into transmittable data, sending it to the control module. This provides the control module with direct temperature information to determine whether to start / adjust the cooling system.

[0031] The dustproof module will be described in detail below, including: Centrifugal fans are used to draw in purified air based on a second command, maintaining stable air pressure within the vehicle control box. The air pressure sensor is used to measure the initial air pressure inside the vehicle control box and send the initial air pressure to the control module.

[0032] Specifically, the centrifugal fan is the aerodynamic source for the dustproof module. It is typically a small, low-noise centrifugal fan integrated into the air intake path of the vehicle control box. Upon receiving a second command from the control module, it generates pressure through impeller rotation, drawing purified air filtered by the dustproof filter into the box. Simultaneously, the fan speed can be adjusted to control the airflow, maintaining the air pressure inside the box at a stable level slightly higher than the external ambient pressure. This prevents unfiltered, dusty external air from seeping in through gaps and interfaces in the control box, thus satisfying the ventilation requirements inside the box while enhancing the dustproof effect.

[0033] A pressure sensor is a component that monitors the air pressure inside the enclosure. These are typically high-precision micro-pressure sensors that can be installed inside the vehicle's control box, away from the air intake. It detects the initial air pressure value inside the enclosure and transmits the pressure signal (usually converted to a digital signal) to the control module. The control module can then compare the initial air pressure with a preset air pressure threshold (such as a standard value slightly higher than the external atmospheric pressure) to determine whether to start, stop, or adjust the speed of the centrifugal fan, dynamically maintaining a positive pressure environment inside the enclosure and ensuring the effective operation of the dustproof module.

[0034] The dust removal module is described in detail below, including: The blowing unit, located on top of the vehicle control box, is used to blow compressed air into the vehicle control box based on a third command. The adsorption plate, located at the bottom of the vehicle control box, is used to adsorb free dust by being powered on based on a third command. A dust concentration sensor is used to measure the initial dust concentration inside the vehicle control box and send the initial dust concentration to the control unit.

[0035] Specifically, the blowing unit is the active dust removal component of the dust removal module, typically consisting of a corrosion-resistant alloy blowing pipe, an electromagnetic pulse valve, and a small high-pressure air tank. It can precisely target and blow dust onto components prone to dust accumulation, such as circuit boards and heat sink fins within the enclosure. Upon receiving a third command from the control unit, the electromagnetic pulse valve quickly activates, and compressed air flows through the blowing pipe to form a high-speed, directional airflow, adhering to and removing dust in a pulsed manner. Simultaneously, the blowing sequence can be synchronized with the energization status of the adsorption plate, ensuring that the blown-off dust is captured by the adsorption plate below while still in suspension, preventing dust from spreading to other areas.

[0036] The adsorption plate is the dust collection component of the dust removal module. It can be made of conductive fiber composite substrate with a highly adsorbent electrostatic film on the surface. The edge is fixed to the bottom of the vehicle control box by an insulating bracket, forming a vertical airflow path of blowing upward and sucking downward with the top blowing unit. This can avoid dust accumulation and reduce adsorption efficiency. At the same time, the insulating bracket can isolate the interference of static electricity on the circuit inside the box.

[0037] Dust concentration sensors serve as status sensing elements for dust removal modules. These often employ high-precision sensors based on laser scattering principles and can be embedded in the center of the vehicle's control box. They continuously emit infrared laser light; when the laser passes through the air inside the box, dust particles scatter the laser beam. The intensity of the scattered light is captured and converted into an electrical signal. The processing module calculates the initial dust concentration and transmits it to the control unit. The control unit then makes a judgment; for example, if the initial dust concentration exceeds a preset threshold, a third command is triggered to activate the blowing unit and adsorption plate. When the concentration drops below the threshold, the unit automatically shuts down, achieving energy-saving control through on-demand dust removal.

[0038] For example, Figure 2 This is a schematic diagram of the engineering structure of another vehicle-mounted control box device provided in an embodiment of this disclosure. From... Figure 2 As can be seen from the diagram: 1 is the main body of the control box; 2 is the cooling air inlet; 3 is the centrifuge; 4 is the liquid pipeline inlet / outlet; 5 is the ash discharge port; 6 is the cooling plate; 7 is the circulating water pump; 8 is the external radiator; 9 is the centrifugal fan; 10 is the filter; 11 is the air pressure sensor; 12 is the air nozzle; 13 is the electrostatic adsorption plate; 14 is the temperature sensor; 15 is the dust concentration sensor; and 16 is the 5G communication module. This vehicle-mounted control box device, through multi-module collaboration, achieves intelligent thermal management of the internal environment, efficient dust prevention and removal, and real-time status monitoring and remote interconnection. Specifically, in terms of thermal management, a circulating water pump drives the coolant to circulate between the cooling plate and the external radiator. The cooling plate provides liquid cooling for the heat-generating components inside the enclosure. Simultaneously, a centrifugal fan draws in air purified by a filter from the cooling air inlet and blows it directionally to key components through air nozzles to enhance air cooling. This dual cooling system ensures that the temperature inside the enclosure remains within a suitable range. Regarding dust prevention and removal, the filter first performs primary filtration of the incoming air, and a dust concentration sensor monitors the dust concentration inside the enclosure in real time. When the concentration exceeds a threshold, an electrostatic adsorption plate is energized to adsorb free dust. Accumulated dust can be periodically discharged through the ash outlet, and the centrifugal fan maintains a slight positive pressure inside the enclosure, reducing the infiltration of dusty external air. In terms of monitoring and connectivity, a pressure sensor and a temperature sensor monitor the air pressure and temperature inside the enclosure, respectively. Together with the dust concentration sensor, they provide environmental parameters to the control unit to intelligently regulate the operating status of each module. Simultaneously, a 5G communication module supports remote real-time transmission of the equipment status inside the enclosure and cloud monitoring, helping to improve operational efficiency and thus comprehensively ensuring the reliable operation of the vehicle control box under vehicle conditions.

[0039] The following section will explain in detail the status data of the control module and how the control module determines and issues commands: Status data includes at least one of the following: temperature, air pressure, and dust concentration.

[0040] Specifically, status data can be understood as the real-time operating environment parameters of the on-board control box. Temperature refers to the real-time temperature value of the core components (such as the CPU and power module) inside the control box. This data directly reflects the thermal load of the components; excessively high or low temperatures may affect the stability and lifespan of the equipment. Air pressure refers to the pressure difference between the inside and outside of the control box, used to monitor the sealing performance of the box. Abnormal pressure fluctuations may indicate damage to the sealing structure, making it easier for external impurities to enter. Dust concentration refers to the mass or quantity concentration of suspended dust particles in the air inside the control box. Dust accumulation increases the risk of short circuits, component wear, and other malfunctions.

[0041] When the control module determines whether to send a command, it includes: When the first temperature does not meet the first condition, the control module sends a first instruction to the liquid cooling module; the first condition includes at least one of the following: a preset temperature threshold and a preset temperature rise rate; When the first air pressure does not meet the second condition, the control module sends a second instruction to the dustproof module; the second condition includes at least one of the following: a preset air pressure threshold and a preset air pressure fluctuation range; When the first dust concentration does not meet the third condition, the control module sends a third instruction to the dust removal module; the third condition includes at least one of the following: a preset dust concentration threshold and a preset dust concentration duration.

[0042] In this disclosure, the first condition can be a preset temperature threshold, a preset temperature rise rate, or a combination of conditions. For example, if the first temperature exceeds the preset temperature threshold (e.g., 85℃), or the temperature rise rate exceeds a preset value (e.g., 10℃ / min) within a set time (e.g., 5 minutes), the first condition is deemed not met. The second condition can be a preset air pressure threshold, a preset air pressure fluctuation range, or a combination of conditions. For example, if the first air pressure is lower than a preset negative pressure threshold (e.g., -5kPa), or the air pressure fluctuation range exceeds a preset range (e.g., ±3kPa) within a unit time (e.g., 1 minute), the second condition is deemed not met. The third condition can be a preset dust concentration threshold, a preset dust concentration duration, or a combination of conditions. For example, if the first dust concentration is higher than a preset concentration value (e.g., 5mg / m³), and the duration of this concentration state exceeds a preset time (e.g., 30 minutes), the third condition is deemed not met.

[0043] Specifically, the control unit can collect status data such as temperature, air pressure, and dust concentration from the vehicle control box using sensors, and compare the collected real-time data with the first, second, and third conditions pre-stored in the control unit. When a certain status data is detected as not meeting the corresponding condition, a command is generated and sent to the corresponding execution module. At the same time, after the command is sent, the control unit can continue to collect the status data, dynamically adjust the command execution intensity based on data changes, or stop the command when the data meets the condition, ensuring that the vehicle control box is always in a stable operating environment.

[0044] The following will explain in detail how the control module makes its judgments, including: The control unit selects to send a first command, a second command, and / or a third command based on an adaptive method; the adaptive method includes at least one of the following: multi-sensor data fusion and dynamic priority adjustment.

[0045] In this disclosure, the adaptive method can be understood as an intelligent decision-making approach in which the control unit flexibly adjusts its command transmission strategy based on the real-time operating conditions of the vehicle control box. Specifically, multi-sensor data fusion refers to integrating state data collected by multiple sensors of the same or different types (such as temperature values ​​from different areas collected by multiple temperature sensors, or correlation data between temperature and humidity sensors and barometric pressure sensors), and reducing the measurement error of a single sensor through at least one processing step such as data calibration, redundancy analysis, and feature extraction, thereby improving the accuracy and reliability of the state data and providing a more comprehensive basis for command judgment. Dynamic priority adjustment refers to dynamically setting the priority of command transmission based on the degree of impact of different state parameters on the operational safety of the vehicle control box and the degree to which real-time data deviates from preset conditions. For example, when the temperature is severely exceeded and the barometric pressure is simultaneously abnormal, the first command related to temperature is sent first, and the barometric pressure abnormality is addressed only after the temperature is brought under control.

[0046] The following details the further features of the vehicle control box disclosed herein: An abnormal alarm module is used to perform an alarm operation based on an abnormal signal from the control module; the abnormal signal includes at least one of the following: at least one of a first temperature, a first air pressure, and a first dust concentration exceeds a preset safety threshold, or coolant leakage.

[0047] In this disclosure, abnormal signals refer to status signals detected by the control module that may cause malfunctions or safety risks to the vehicle control box. The preset safety threshold is a more stringent limit value than the preset conditions mentioned above, and the coolant leakage signal is a leakage of the liquid cooling module.

[0048] Specifically, after receiving an abnormal signal from the control module, the abnormal alarm module can activate a multi-level alarm mechanism: first, a text alarm message will pop up on the vehicle display screen, and at the same time, a buzzer will be triggered to emit an audible and visual alarm; if the abnormal state continues for a preset time (such as 5 minutes) without being relieved, alarm data, including the abnormality type, occurrence time, and real-time status parameters, can be further sent to the remote monitoring platform; in addition, it can also be linked to the emergency stop module of the vehicle control box to automatically cut off unnecessary power supply in extreme dangerous situations (such as when the temperature far exceeds the safety threshold and may cause a fire), so as to minimize safety risks.

[0049] For example, Figure 3 This is a flowchart illustrating a control method provided in an embodiment of this disclosure. Figure 3 As shown, the entire control process includes the following steps: Step 1: System initialization, complete sensor self-test (detect temperature, dust, and air pressure), and load preset parameters (temperature threshold of 50℃, dust threshold of 1mg / m³, and positive pressure threshold of 5-10Pa).

[0050] Step 2: Enter the main circulation monitoring phase, and perform three tasks in parallel: temperature monitoring, dust monitoring, and positive pressure maintenance. Temperature monitoring branch: Detects ambient temperature. If the temperature is >50℃, starts the liquid cooling module, causing the circulation pump to operate at a flow rate of 0.5-2L / min to drive the coolant circulation (path from cooling plate to radiator to pump) until the temperature is ≤45℃, at which point the liquid cooling module stops. If the temperature is ≤50℃, the temperature is continuously monitored.

[0051] Dust monitoring branch: Detects dust concentration. If the dust concentration is >1mg / m³ or the timed 4h condition is met, the dust removal module is activated. First, compressed air at 0.3MPa is sprayed, then the dust is discharged through the electrostatic adsorption plate and finally discharged from the ash discharge port. If the dust concentration is not >1mg / m³ and the timed 4h condition is not met, the dust is continuously monitored.

[0052] Positive pressure maintenance branch: Detect air pressure. If the air pressure is <5Pa, increase the fan speed; if the air pressure is ≥5Pa, maintain the current fan status.

[0053] Step 3: Perform data synchronization by uploading real-time monitored temperature, dust, and air pressure data to the industrial control system via a 5G module; if an abnormality is detected (temperature > 60℃ or dust > 5mg / m³), an alarm will be triggered.

[0054] Step 4: Repeat the main loop monitoring and data synchronization process, continuously monitor the system status and interact with data until the control flow ends.

[0055] This disclosure also provides a method for controlling an on-board control box, including: Based on the status data of the vehicle control box, send at least one of the following commands: a first command, a second command, and a third command; Using a liquid cooling module, heat is absorbed and dissipated based on the first command; Using a dustproof module, based on a second command, it draws in air to prevent dust from entering; Using a dust removal module, dust is either blown or adsorbed based on third-party instructions.

[0056] For a detailed explanation, please refer to the above text; it will not be repeated here.

[0057] This disclosure further provides a computer program product, including a computer program that, when executed by a processor, implements the vehicle control box control method described in any of the preceding embodiments of this disclosure.

[0058] In summary, this disclosure provides an on-board control box device, method, and program product. This disclosure utilizes a liquid cooling module disposed outside the heat-generating elements within the on-board control box to absorb and dissipate heat based on a first command from the control module; a dustproof module to draw in air and prevent dust from entering based on a second command from the control module; a dust removal module disposed at the top and bottom of the on-board control box to blow or absorb dust based on a third command from the control module; and a control module to send at least one of the following commands based on the status data of the on-board control box: the first command, the second command, and the third command. Thus, compared to existing manual dust removal and conventional air-cooling methods, this disclosure, through the coordinated control of multiple modules including liquid cooling, pressure dust prevention, and automated dust removal, can achieve efficient cooling and dust removal without system shutdown. In summary, the technical solution provided in this disclosure can effectively solve the problem of high equipment failure rate caused by overheating and dust accumulation in the vehicle control box. It improves heat dissipation efficiency through liquid cooling module, reduces dust accumulation through pressure dustproof design, and avoids the risk of production interruption caused by manual operation through automated dust removal mechanism, thereby reducing the failure rate, improving performance stability, and adapting to a variety of application scenarios.
