Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a vehicle underbody protection plate, a control method for the vehicle underbody protection plate, a vehicle, and a storage medium. Background Technology

[0002] In modern automotive design, underbody protection plates not only play a crucial role in protecting the vehicle's chassis from environmental corrosion, but also significantly contribute to improving aerodynamic performance. A flat underbody protection plate helps reduce air turbulence under the vehicle, thereby lowering drag and improving fuel economy. However, to meet the cooling needs of the engine and other thermal management system components, the front underbody protection plate typically requires vents to guide cool air in, which to some extent increases aerodynamic drag.

[0003] Currently, most cars use a fixed cooling vent design, where the vents remain open regardless of the vehicle's thermal load. While this fixed vent design ensures effective heat dissipation from the thermal management system under high-temperature or high-load conditions, it cannot actively reduce aerodynamic drag at lower thermal loads. As a result, even under low-heat driving conditions, the vehicle still experiences unnecessary aerodynamic drag, thus affecting fuel economy and driving experience.

[0004] There is currently no good solution to the above problems. Summary of the Invention

[0013] Furthermore, in response to the temperature data being higher than or equal to a preset temperature threshold, controlling the motor to drive the telescopic mechanism to retract so that the heat dissipation hole is in an open state includes: in response to the temperature data being higher than or equal to the preset temperature threshold, generating a second drive command based on the controller; controlling the motor to drive the telescopic mechanism to retract based on the second drive command until the second limit switch blocks the baffle.

[0028] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0029] According to an embodiment of this application, an embodiment of a vehicle underbody protection plate is provided. Figure 1 This is a structural schematic diagram of a vehicle underbody protection plate according to one embodiment of this application, as shown below. Figure 1 As shown, the vehicle's underbody protection plate includes:

[0030] The protective plate (4) has heat dissipation holes. The protective plate (4) is equipped with a sealing mechanism, a control device (2) and a thermal monitoring device (1). The thermal monitoring device (1) and the sealing mechanism are connected through the control device (2).

[0031] The thermal monitoring device (1) is used to monitor the temperature data of the vehicle.

[0032] The control device (2) is used to control the operation of the sealing mechanism based on temperature data.

[0033] The blocking mechanism includes a motor (3), a telescopic mechanism (31), and a baffle (32). The size of the baffle (32) matches the size of the heat dissipation hole (5). The motor (3) is used to drive the telescopic mechanism (31) to move, so as to drive the baffle (32) to block or open the heat dissipation hole (5).

[0034] In this embodiment, the vehicle underbody protection plate includes a protection plate (4), a sealing mechanism, a control device (2), and a thermal monitoring device (1). The protection plate (4) is a protective component installed on the bottom of the vehicle, especially under the front compartment. The protection plate (4) is made of corrosion-resistant material and is designed to prevent the chassis from being eroded and damaged by the external environment.

[0035] The guard plate (4) is designed with heat dissipation holes (5) to guide external cold air into the vehicle to cool the engine and other heat sources and prevent heat buildup. The size and position of the heat dissipation holes (5) need to match the baffle (32) to ensure the tightness of the seal and the accuracy and effectiveness of sealing and opening.

[0036] The blocking mechanism consists of a motor (3), a telescopic mechanism (31), and a baffle (32), and is the core component for dynamically blocking the heat dissipation hole (5). The motor (3) drives the telescopic mechanism (31) to drive the baffle (32) to block or open the heat dissipation hole (5).

[0037] The telescopic mechanism (31) is the component responsible for mechanical movement in the vehicle underbody protection plate. It is mainly used to drive the baffle (32) to move between the open and closed positions of the heat dissipation hole (5). The telescopic mechanism (31) is driven by the motor (3). Its design can be a linear sliding guide rail telescopic mechanism or a rotary telescopic mechanism similar to a folding arm, to adapt to different underbody structures and space constraints. No restrictions are imposed here.

[0038] The control device (2) is the center that coordinates the operation of the thermal monitoring device (1) and the sealing mechanism, namely the electronic control unit (ECU). Based on the temperature data provided by the thermal monitoring device (1), the control device (2) generates instructions to control the start or stop of the motor (3) to seal or open the heat dissipation hole (5).

[0039] The thermal monitoring device (1) is used to monitor the temperature changes of the vehicle's heat source and the thermal load status of the thermal management system in real time. The thermal monitoring device (1) can transmit the collected data to the thermal monitoring software of the control device (2) via wired or wireless means, providing a basis for the control of the heat dissipation hole (5).

[0040] As can be seen, the vehicle underbody protection plate of this application collects vehicle temperature information in real time through the thermal monitoring device (1) and analyzes this temperature data through the software algorithm in the control device (2), and can automatically adjust the opening and closing state of the heat dissipation holes (5). The intelligent response mechanism of this application enables the vehicle to achieve optimal aerodynamic performance and thermal management under different thermal load conditions. Furthermore, under low thermal load driving conditions, the sealing mechanism can automatically seal the heat dissipation holes (5), significantly reducing the air resistance at the bottom of the vehicle, thereby reducing the drag coefficient and helping to improve the fuel economy of the vehicle or the range of electric vehicles. In addition, when the vehicle thermal load increases, the heat dissipation holes (5) can open quickly to ensure sufficient cooling air circulation, effectively dissipate heat, protect the engine and other key components from overheating, and extend their service life and reliability. That is, the vehicle underbody protection plate of this application can meet the heat dissipation requirements under high thermal loads without causing unnecessary energy loss under low thermal loads. By intelligently controlling the sealing and opening of the heat dissipation holes, it can effectively balance the contradiction between thermal management and aerodynamic resistance.

[0041] Optionally, the thermal monitoring device (1) includes multiple temperature sensors for monitoring temperature data at different locations on the vehicle.

[0042] In this embodiment, the thermal monitoring device includes multiple temperature sensors used to detect and measure temperature changes. These multiple temperature sensors are deployed in several critical locations within the vehicle, such as areas in direct contact with heat sources (e.g., the engine) and other locations affecting the thermal management system.

[0043] For example, the temperature sensor can be a thermistor, thermocouple or infrared temperature sensor, etc. Multiple temperature sensors are connected to the thermal monitoring software in the controller (2) by wired or wireless means to transmit temperature data to the thermal monitoring software for data analysis in real time.

[0044] Therefore, by deploying temperature sensors at different locations on the vehicle, the thermal monitoring device (1) can comprehensively and accurately understand the thermal load status of the entire vehicle. This multi-point monitoring method ensures that the thermal management system's decisions are based on complete temperature data, improving the system's intelligence level and response speed.

[0045] Optionally, the controller (2) integrates a motor drive circuit, which is used to drive the motor to run.

[0046] In this embodiment, the motor drive circuit is a key component of the controller (2), and its main function is to provide the necessary current and voltage to the motor (3) to drive the motor (3) to run.

[0047] For example, the circuit design of the motor drive circuit takes into account the power requirements, start-stop control and speed regulation of the motor, and has safety features such as overcurrent protection and short circuit protection to ensure the stable and safe operation of the motor (3) under various operating conditions.

[0048] Therefore, the motor drive circuit can accurately control the operating state of the motor (3), including the start, stop, and speed of the motor (3), ensuring that the baffle (32) of the blocking mechanism moves accurately and quickly when blocking the heat dissipation hole (5) and opening the heat dissipation hole (5), thereby improving the system's response speed and control accuracy.

[0049] Optionally, a first limit switch is installed at the preset extended position of the telescopic mechanism, and a second limit switch is installed at the preset retracted position of the telescopic mechanism.

[0050] In this embodiment, the limit switch is an electromechanical component used to cut off the drive signal of the motor (3) or change its working state when the baffle (32) reaches the preset position.

[0051] The first limit switch is installed at the preset extension position of the telescopic mechanism (31), that is, the position when the baffle (32) is fully extended and ready to block the heat dissipation hole (5). When the baffle (32) contacts the first limit switch, the first limit switch sends a trigger signal to the controller (2), indicating that the baffle (32) has reached the blocking position of the heat dissipation hole (5). At this time, the controller (2) will control the motor (3) to stop working to prevent overextension and damage.

[0052] The second limit switch is installed at the preset retracted position of the telescopic mechanism (31), that is, when the baffle (32) is fully retracted and the heat dissipation hole (5) is open. Similar to the first limit switch, the function of the second limit switch is to interrupt the signal of the motor (3) after the baffle (32) is completely away from the heat dissipation hole (5), so as to avoid the baffle (32) from retracting excessively or the motor (3) from running idle, thus also playing a protective role.

[0053] Therefore, the presence of the limit switch ensures that the telescopic mechanism (31) moves accurately, avoids physical damage to the mechanism itself and the heat dissipation hole (5) caused by excessive movement, and improves the reliability and stability of the vehicle underbody protection plate.

[0054] Figure 2 This is a schematic diagram of the installation position of a vehicle underbody protection plate according to one embodiment of this application, as shown below. Figure 2 As shown, the vehicle underbody protection plate of this application can be installed at the bottom of the vehicle, specifically under the front compartment of the vehicle.

[0055] In summary, the vehicle underbody protection plate of this application includes the following four components:

[0056] Thermal monitoring device (1): Used for real-time monitoring of the vehicle's thermal load. The thermal monitoring device (1) may include multiple temperature sensors, which may be of various types such as thermistors, thermocouples, or infrared temperature sensors. The collected temperature data is sent to the thermal monitoring software in the ECU via wired or wireless means. The temperature sensors are installed near key components such as the engine and transmission. The thermal monitoring device (1) also includes a thermal load calculation unit, which calculates the vehicle's real-time thermal load based on the temperature data collected by each temperature sensor.

[0057] The thermal monitoring software uses advanced algorithms to analyze temperature data. For example, by setting different temperature thresholds, the software can determine whether the vehicle's thermal management system is operating normally when the temperature exceeds or falls below these thresholds. Simultaneously, the software can predict temperature change trends and react in advance. The software also has fault diagnosis capabilities; when the thermal monitoring device (1) malfunctions or displays abnormal data, it can issue an alarm promptly and record fault information for subsequent maintenance personnel to investigate.

[0058] Controller (2): Connected to the thermal monitoring device (1) and the sealing mechanism, it controls the action of the sealing mechanism based on the thermal load information provided by the thermal monitoring device (1). It receives control commands sent by the thermal monitoring software. The controller (2) can be an independent electronic control unit or a module integrated into other automotive control systems. The main function of the controller (2) is to control the start, stop, speed, and other parameters of the motor (3) according to the instructions of the thermal monitoring software.

[0059] The controller (2) has a motor drive circuit inside, which can provide appropriate current and voltage to the motor (3), and also has overcurrent protection, short circuit protection and other functions to ensure the safe operation of the motor (3). At the same time, the controller (2) can monitor the working status of the motor (3) in real time, such as the speed and current of the motor (3) and feed this information back to the thermal monitoring software so that the thermal monitoring software can perform further analysis and adjustment.

[0060] The sealing mechanism includes a motor (3), a telescopic mechanism (31), and a baffle (32). It is installed at the heat dissipation hole (5) on the lower front panel of the vehicle and is used to seal or open the heat dissipation hole (5). The telescopic mechanism (31) can adopt a telescopic baffle structure (the baffle (32) is the same size as the heat dissipation hole (5). The telescopic mechanism (31) is driven by the motor (3) to extend to the position corresponding to the heat dissipation hole (5) to seal the heat dissipation hole (5), thereby sealing or opening the heat dissipation hole (5).

[0061] Limit switches are located at the extension and retraction limit positions of the telescopic mechanism (31). When the baffle (32) contacts the limit switch, the internal mechanical structure of the limit switch is triggered, closing or opening the circuit. The limit switch sends a trigger signal to the controller (2), which determines whether the baffle (32) has reached or left the heat dissipation hole based on the signal. This is used to protect the baffle and the motor from excessive movement.

[0062] Protective plate (4).

[0063] According to an embodiment of this application, a method embodiment for controlling a vehicle underbody protection plate is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0064] This embodiment provides a method for controlling a vehicle underbody protection plate, which is applied to the vehicle underbody protection plate described in the above embodiment. Figure 3 This is a flowchart of a control method for a vehicle underbody protection plate according to one embodiment of this application, such as... Figure 3 As shown, the process includes the following steps:

[0065] Step S31: Monitor the temperature at a preset location in the vehicle and obtain temperature data.

[0066] In this embodiment, the preset location refers to the key heat source area in the vehicle related to thermal management, such as the engine, transmission, battery pack, or cooling system. The temperature changes in these locations are directly related to the overall thermal load status of the vehicle.

[0067] Temperature data refers to the temperature information of a preset location on the vehicle, which is collected and transmitted in real time by temperature sensors. The temperature data is used to assess the current working status and requirements of the vehicle's thermal management system.

[0068] As can be seen, this application monitors the temperature of vehicle heat source areas in real time, such as the engine temperature. Continuous monitoring of temperature data provides real-time feedback to the vehicle's thermal management system, enabling the system to respond promptly to temperature changes and avoid performance degradation or component damage caused by excessive heat load. Furthermore, accurate temperature data allows for more accurate decisions regarding the opening and closing of heat dissipation vents, improving the efficiency and intelligence of thermal management.

[0069] In step S32, in response to the temperature data being lower than the preset temperature threshold, the motor is controlled to drive the telescopic mechanism to extend until the baffle completely blocks the heat dissipation hole.

[0070] In this embodiment, the preset temperature threshold can be 100℃, set according to actual conditions. When the temperature data is lower than this threshold, it is determined that the vehicle's heat load is low, and therefore no additional heat dissipation is required through the heat dissipation hole (5). At this time, the motor (3) can be controlled to drive the telescopic mechanism (31) to extend the baffle (32) to the position of the heat dissipation hole (5), and the first limit switch is used to ensure that the baffle (32) completely blocks the heat dissipation hole (5), reducing airflow and thus reducing wind resistance.

[0071] Therefore, by blocking the heat dissipation holes (5), air resistance is reduced, the aerodynamic performance of the vehicle is improved, and energy consumption is reduced. For fuel vehicles, this can reduce fuel consumption, and for electric vehicles, it can increase the driving range.

[0072] In step S33, in response to the temperature data being higher than or equal to a preset temperature threshold, the motor is controlled to drive the telescopic mechanism to retract so that the heat dissipation vents are in an open state.

[0073] In this embodiment, when the temperature data reaches or exceeds a preset temperature threshold, it is determined that the vehicle's heat load is high and more heat dissipation is needed to maintain the normal operating temperature of the engine and other key components. At this time, the motor (3) can be controlled to drive the telescopic mechanism (31) to retract the baffle (32) to ensure that the heat dissipation hole (5) is fully open so that cold air can enter and carry away excess heat.

[0074] Therefore, under high heat load conditions, the automatic opening of the heat dissipation vents (5) ensures effective heat dissipation of the thermal management system, avoids overheating of the heat source, and protects the engine and other critical components. In addition, this application can automatically adjust the opening and closing state of the heat dissipation vents (5) according to the actual heat load of the vehicle, enhancing the adaptability and flexibility of the system, and maintaining the vehicle's optimal operating state under any driving conditions.

[0075] In summary, this application achieves an intelligent balance between vehicle thermal management and aerodynamic performance. Under low heat load conditions, the system automatically seals the cooling vents to reduce wind resistance and energy consumption. Under high heat load conditions, the system can quickly open the cooling vents to ensure good heat dissipation. This automated control not only improves the vehicle's operating efficiency and economy but also protects critical components and extends the vehicle's service life.

[0076] The above steps of this application involve monitoring the temperature at a preset location within the vehicle to obtain temperature data; responding to a temperature data below a preset temperature threshold, controlling a motor to extend a telescopic mechanism until the baffle completely blocks the heat dissipation vents; responding to a temperature data above or equal to the preset temperature threshold, controlling a motor to retract the telescopic mechanism to open the heat dissipation vents. This achieves the goal of intelligently regulating the opening and closing of the heat dissipation vents based on the heat load, thereby enhancing the system's adaptability and flexibility. It maintains the vehicle's optimal operating state under all driving conditions, achieving a technical effect of intelligent balance between vehicle thermal management and aerodynamic performance. This solves the technical problem in related technologies where fixed heat dissipation vents cause unnecessary aerodynamic drag even under low-heat-load driving conditions.

[0077] Optionally, in step S31, monitoring the temperature at a preset location in the vehicle to obtain temperature data may include the following steps:

[0078] Step S311: Initial temperature data at different locations on the vehicle are monitored using multiple temperature sensors.

[0079] Step S312: Perform data analysis on the initial temperature data to obtain temperature data.

[0080] In this embodiment, when monitoring the temperature at a preset location in the vehicle to obtain temperature data, initial temperature data at different locations in the vehicle can be monitored using multiple temperature sensors. It can be seen that multiple temperature sensors will monitor the preset key heat source areas in the vehicle in real time. These multiple temperature sensors can be thermistors, thermocouples, infrared temperature sensors, etc. These sensors can accurately measure the temperature at their location and transmit this initial temperature data to the thermal monitoring software in the controller (2) via wired or wireless means. This data acquisition process is continuous, ensuring real-time monitoring of the vehicle's thermal state.

[0081] Therefore, the use of multiple sensors ensures comprehensive coverage of the vehicle's heat source area, enabling timely detection of potential temperature anomalies and improving the monitoring accuracy and reliability of the thermal management system.

[0082] Then, the initial temperature data is analyzed to obtain the final temperature data. It can be seen that after receiving initial temperature data from multiple temperature sensors, the thermal monitoring software performs in-depth analysis of this data. This includes, but is not limited to, data cleaning (removing invalid or abnormal data), statistical analysis (calculating average temperature, temperature difference, etc.), and trend prediction (analyzing temperature change trends). Through this series of data analyses, the thermal monitoring software can determine the vehicle's current thermal load and use the processed temperature data for subsequent control decisions.

[0083] Therefore, the results of the data analysis provide a basis for intelligent decision-making for the subsequent opening and closing control of the heat dissipation holes (5), enabling the system to respond according to the specific thermal load state of the vehicle.

[0084] Optionally, in step S32, responding to the temperature data being lower than a preset temperature threshold, controlling the motor to drive the telescopic mechanism to extend until the baffle completely blocks the heat dissipation holes may include the following steps:

[0085] Step S321: In response to the temperature data being lower than a preset temperature threshold, a first drive command is generated based on the controller.

[0086] In step S322, the control motor drives the telescopic mechanism to extend based on the first drive command until the first limit switch stops the baffle.

[0087] In this embodiment of the application, when the temperature data is lower than the preset temperature threshold, a first driving command is generated based on the controller. Then, the control motor drives the telescopic mechanism to extend based on the first driving command until the first limit switch blocks the baffle.

[0088] The first driving command is a command generated by the controller (2) to instruct the motor (3) to drive the telescopic mechanism (31) to extend so as to block the heat dissipation hole (5).

[0089] It can be seen that when the temperature data collected by the thermal monitoring device (1) is lower than the preset temperature threshold (e.g., 100℃), the thermal monitoring software determines that the current vehicle heat load is low, and the heat dissipation hole (5) should be closed to reduce wind resistance. Subsequently, the thermal monitoring software sends a signal to the control device (2), and the control device (2) generates a first drive command based on the signal. This first drive command may include parameters for starting the motor, setting the motor speed and running direction, so that the motor (5) drives the telescopic mechanism (31) to perform the extension action.

[0090] After receiving the first drive command, the motor (3) starts running, driving the telescopic mechanism (31) to move the baffle (32) from its current position toward the heat dissipation hole (5). This process continues until the baffle (32) contacts the first limit switch, which is triggered to stop the motor (3) by interrupting or changing the drive signal of the motor (3), ensuring that the baffle (32) accurately reaches and completely blocks the heat dissipation hole (5).

[0091] Figure 4 This is a schematic diagram of the heat dissipation hole sealing state according to one embodiment of this application, as shown below. Figure 4As shown, the baffle (32) will completely block the heat dissipation hole (5). Thus, the controller (2) can make the decision to block the heat dissipation hole (5) based on real-time temperature data, rather than a fixed procedure, enhancing the intelligence and adaptability of the system. In addition, the first limit switch prevents the baffle (32) from extending excessively, protecting the mechanical structure and reducing maintenance costs and failure rate.

[0092] Optionally, in step S33, responding to the temperature data being higher than or equal to a preset temperature threshold, controlling the motor to drive the telescopic mechanism to retract so that the heat dissipation vents are open may include the following execution steps:

[0093] Step S331: In response to the temperature data being higher than or equal to a preset temperature threshold, a second drive command is generated based on the controller.

[0094] In step S332, the control motor drives the telescopic mechanism to retract based on the second drive command until the second limit switch locks the baffle.

[0095] In this embodiment of the application, when the temperature data is higher than or equal to the preset temperature threshold, a second driving command will be generated based on the controller. Then, the control motor will drive the telescopic mechanism to retract based on the second driving command until the second limit switch blocks the baffle.

[0096] It can be seen that when the temperature data collected by the thermal monitoring device (1) is higher than or equal to the preset temperature threshold (e.g., 100℃), it is determined that the vehicle's thermal load is high and more heat dissipation is needed to maintain the normal operating temperature of the engine and other key components. At this time, the thermal monitoring software will send a signal to the control device (2), and the control device (2) will generate a second drive command based on this signal. The second drive command may include parameters for starting the motor, setting the motor speed and running direction, so that the motor (5) drives the telescopic mechanism (31) to perform the retraction action.

[0097] After receiving the second drive command, the motor (3) drives the telescopic mechanism (31) to retract the baffle (32). When the baffle (32) is completely removed from the heat dissipation hole (5) and reaches the preset retracted position, the second limit switch is triggered, interrupting the operation of the motor (3) and ensuring that the telescopic mechanism (31) does not continue to retract, thereby avoiding damage caused by excessive retraction of the baffle (32). Thus, the second limit switch ensures that the baffle (32) accurately stops in the open state of the heat dissipation hole, avoiding excessive movement and improving the reliability of the system.

[0098] Figure 5 This is a schematic diagram showing the heat dissipation hole in an open state according to one embodiment of this application, as shown below. Figure 5As shown, the baffle (32) will fully open the heat dissipation hole (5). In summary, this application can automatically and intelligently adjust the opening and closing state of the heat dissipation hole (5) according to the actual heat load of the vehicle. Under high heat load conditions, the heat dissipation hole (5) is opened in time to effectively improve heat dissipation efficiency and ensure vehicle performance and safety. Under low heat load conditions, the heat dissipation hole (5) is blocked to reduce wind resistance, save energy consumption, and improve driving economy.

[0099] Figure 6 This is another flowchart of a control method for a vehicle underbody protection plate according to one embodiment of this application, as follows: Figure 6 As shown, the ECU monitors the temperature at specific locations within the engine compartment, calculating the vehicle's real-time heat load based on temperature data collected by various temperature sensors. When the heat load falls below a preset threshold of 100°C, the control unit sends a signal to the motor-driven telescopic mechanism to extend, moving the baffle to the heat dissipation vents where it is stopped by a limiting mechanism to prevent excessive movement. This causes the sealing mechanism to block the heat dissipation vents on the engine compartment cover.

[0100] When the heat load is not lower than the preset threshold of 100℃, the control unit sends a signal to the motor to drive the telescopic mechanism to retract, which in turn moves the baffle to open the heat dissipation holes on the engine compartment guard plate. During the retraction process, it is determined whether the guard plate has completely left the heat dissipation holes. If so, the baffle is locked by a limiting mechanism to open the heat dissipation holes, facilitating heat management and heat dissipation. Otherwise, the baffle continues to retract until the heat dissipation holes are open.

[0101] Therefore, this application can simultaneously address the needs of thermal management and heat dissipation while reducing air resistance. It opens vents for heat dissipation when the vehicle's thermal load is high and automatically seals the vents when the vehicle's thermal load is low, reducing air resistance and thus lowering fuel consumption. Furthermore, it promptly opens the vents when the thermal load is high to ensure proper heat dissipation for critical components such as the engine, extending their service life. In addition, the automatic control of vent sealing is achieved through the cooperation of thermal monitoring software and a control unit, improving the system's intelligence and reliability. Moreover, the materials used in the device have low requirements, no high-precision machining requirements, and simple assembly, saving on processing labor costs.
