Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] It is understandable that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0021] Active grille shutters automatically adjust the opening and closing degree of the air intake grille according to vehicle driving conditions, such as vehicle speed and engine temperature, thereby optimizing the vehicle's aerodynamic performance, reducing wind resistance, and reducing fuel consumption. They also help the engine reach its optimal operating temperature quickly, improving engine efficiency and reliability. Currently, active grille shutters mainly use rotary adjustment, with each intake baffle having a rotating shaft. If driven by a linkage mechanism, the connection points between the links are prone to loosening and wear, affecting the normal operation of the grille. Furthermore, the complex linkage structure increases assembly difficulty and cost.

[0022] Based on this, this application discloses an air intake grille, a control method, a device, and a medium. By setting multiple second vertical plates with equal spacing from the first vertical plate, and driving the air intake baffles 200 to move within guide holes via a drive assembly, the grille frame is obstructed, thereby optimizing the vehicle's aerodynamic performance. This application uses a horizontal movement method to adjust the opening and closing degree of the air intake grille. Compared to a rotary adjustment, this reduces the connection structure between the various air intake baffles 200, thereby improving the reliability of the air intake grille adjustment and reducing the assembly difficulty of the air intake grille.

[0023] Firstly, referring to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an air intake grille provided in an embodiment of this application. Figure 2 This is a schematic diagram of the structure of the air intake baffle provided in an embodiment of this application.

[0024] Understandably, the air intake grille includes a grille frame, an air intake baffle 200, and a drive assembly. The grille frame includes a base 100, with multiple first vertical plates 110 evenly spaced at the bottom of the base 100. The multiple first vertical plates 110 are parallel to each other, and a guide hole is provided at the bottom of the base 100. The air intake baffle 200 includes a first horizontal plate 210 and multiple second vertical plates 220 evenly spaced at the first horizontal plate 210. The air intake baffle 200 passes through the guide hole, and the length of the baffle 200 is less than the length of the guide hole, so that the air intake baffle 200 can move within the guide hole. The extension direction of the guide hole is either the arrangement direction of the first vertical plates 110 or the arrangement direction of the second vertical plates 220. By moving the position of the air intake baffle 200, the air intake baffle 200 blocks the gaps between the first vertical plates 110, thereby adjusting the opening of the air intake grille. The interval between two adjacent first vertical plates 110 is equal to that between two adjacent second vertical plates 220. The width of the second vertical plate 220 is greater than or equal to the interval between two adjacent first vertical plates 110, so that the second vertical plate 220 can completely cover the gap between two adjacent first vertical plates 110. A drive assembly is installed on one side of the grille frame. The drive end of the drive assembly is connected to the air intake baffle 200 to drive the air intake baffle 200 to move within the guide through hole, thereby blocking the interval between two adjacent first vertical plates 110.

[0025] It should be noted that the grille frame also includes a base plate 120, a first side plate 130, and a second side plate 140. The base plate 120 is connected to the end of the first vertical plate 110 away from the base 100. The base plate 120 has a guide groove, and the second vertical plate 220 is installed in the guide groove. One end of the first side plate 130 is connected to one side of the base plate 120, and the other end of the first side plate 130 is connected to the base. One end of the second side plate 140 is connected to one side of the base plate 120, and the other end of the second side plate 140 is connected to the base. The base plate 120 is connected to the first side plate 130, the second side plate 140, and the first vertical plate 110 to form a stable mechanism with the base plate 120, thereby improving the stability of the air intake grille. In addition, the limiting effect of the guide groove and guide through hole on the air intake baffle 200 can ensure the movement stability of the air intake baffle 200.

[0026] The drive assembly includes a drive motor 300 and a connecting screw 310. The drive motor 300 is mounted on the outside of the base 100. The base 100 has a first through hole near the drive motor 300. The connecting screw 310 is connected to the drive end of the drive motor 300 and passes through the first through hole. A sliding member 320 is provided on the connecting screw 310, and the sliding member 320 is connected to the first horizontal plate 210. The drive motor 300 drives the connecting screw 310 to rotate, and the drive screw drives the first horizontal plate 210 to move in the guide through hole through the sliding member 320. The rotational motion of the drive motor 300 can be converted into linear motion by the drive screw. Compared with rotary adjustment, this reduces the connection structure between the various air intake baffles 200, thereby improving the adjustment reliability of the air intake grille and reducing the assembly difficulty of the air intake grille.

[0027] Secondly, referring to Figure 3 , Figure 3 A detailed flowchart of the air intake grille control method provided in the embodiments of this application includes, but is not limited to, the following steps: Step S100: Obtain vehicle speed information and vehicle engine coolant temperature; Step S200: Adjust the working state of the drive components according to the vehicle speed information, engine coolant temperature and the preset grille opening relationship table.

[0028] Understandably, vehicle speed information directly affects the vehicle's wind resistance and cooling requirements. At high speeds, even with a higher engine coolant temperature, ample headwinds may reduce reliance on the air intake grille; at low speeds or idling, the grille needs to provide more airflow to aid cooling. For example, the grille opening can be reduced at high speeds and increased at low speeds. Furthermore, when the coolant temperature is high, more cooling air needs to be introduced; when the temperature is normal or low, the grille opening can be reduced to decrease wind resistance and improve fuel economy. Therefore, by acquiring vehicle speed and engine coolant temperature information, and based on this information and a preset grille opening relationship table, the operating status of the drive components can be adjusted to ensure the engine warms up quickly and stabilizes at its efficient operating temperature under various conditions, avoiding overheating or overcooling, which helps reduce wear and emissions.

[0029]

[0030] As shown in the figure above, a grid opening relationship table is provided for the embodiment.

[0031] Specifically, at lower vehicle speeds, even with lower engine coolant temperatures, the operating state of the drive assembly can be adjusted to ensure efficient heat dissipation. This allows the second vertical plate to overlap with the first vertical plate, meaning the second vertical plate does not obstruct the gap between adjacent first vertical plates. Conversely, at higher engine coolant temperatures, the operating state of the drive assembly can be adjusted again to ensure the second vertical plate overlaps with the first vertical plate, further improving engine cooling efficiency. A larger target opening indicates less obstruction of the gap between adjacent first vertical plates by the second vertical plate, while a smaller target opening indicates more obstruction.

[0032] It should be noted that the air intake grille also includes a controller, which is connected to the engine coolant temperature acquisition device, the vehicle speed information acquisition device, and the drive assembly. The drive motor has a built-in Hall sensor for position feedback. The controller can use the Hall sensor to determine whether the drive motor has reached a preset position, thereby determining whether the second vertical plate has reached the predetermined position.

[0033] Understandably, different driving conditions necessitate different adjustments to the air intake grille. For example, if the vehicle is wading through water, water may enter the motor through the grille, potentially damaging it. Therefore, in wading situations, the blade opening can be controlled to 30% to ensure basic heat dissipation while reducing the risk of water impact on the motor. The presence of wading can be determined using a rain sensor or camera. Thus, by acquiring the vehicle's driving status and responding to vehicle speed, engine coolant temperature, and whether the driving condition meets preset adjustment conditions, the operating state of the drive components is adjusted according to the corresponding adjustment parameters. These preset adjustment conditions can include vehicle speed, engine coolant temperature, and whether the vehicle is wading through water.

[0034] It should be noted that if the operating current of the drive motor exceeds a preset current threshold, it indicates a potential risk of motor stall. Therefore, in response to the duration of the operating current exceeding the preset current threshold reaching the alarm duration, the controller stops the drive assembly and issues an alarm signal. Furthermore, in some embodiments, if the operating current of the drive motor exceeds the preset current threshold, the controller can first control the drive motor to adjust the position of the air intake baffle to the alarm position, and then control the drive assembly to stop working and issue an alarm signal, ensuring the heat dissipation efficiency of the air intake grille.

[0035] Thirdly, refer to Figure 4This application provides an operation control device 400, including a memory 410, a processor 420, and a computer program stored in the memory 410 and executable on the processor 420.

Furthermore, the memory 410 may include a high-speed random access memory 410, and may also include non-transitory memory 410, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device. It should be noted that the memory 410 may include remotely located memories 410 relative to the processor 420, and these remote memories 410 can be connected to the terminal via a network.
