Abstract

[0002] In related technologies, aerodynamic control devices are widely used in the automotive field to optimize the aerodynamic performance of vehicles during driving. Common aerodynamic control devices mainly control airflow through fixed or adjustable deflectors to reduce wind resistance or increase downforce.

[0048] This application provides an airflow regulating device, such as... Figure 1 As shown, the airflow regulating device includes a first flow guiding structure 1, a second flow guiding structure 2, a driving mechanism 3, and a rotating shaft 4. The first flow guiding structure 1 is connected to the rotating shaft 4 and rotates around the rotating shaft 4. The second flow guiding structure 2 is connected to the rotating shaft 4 and rotates around the rotating shaft 4. The driving mechanism 3 is used to drive the first flow guiding structure 1 and / or the second flow guiding structure 2 to rotate around the rotating shaft 4.
[0049] In the above embodiments, the synchronous rotation of the first airflow guiding structure 1 and the second airflow guiding structure 2 can be achieved through the linkage of the rotating shaft 4, thereby switching between diffuser mode and baffle mode. In some embodiments, the first airflow guiding structure 1 may include a first flat plate 8, and the second airflow guiding structure 2 may include a second flat plate 9. This scheme can effectively change the airflow distribution characteristics by adjusting the tilt angle of the flat plate structure. In some embodiments, the included angle between the first airflow guiding structure 1 and the second airflow guiding structure 2 is 5°-20°. This scheme, by reasonably setting the included angle range, ensures both structural compactness and significant improvement in aerodynamic performance. In some embodiments, the first airflow guiding structure 1 also includes a first enclosure plate 10. This scheme, through the connection of the first enclosure plate 10 and the subframe mudguard, can enhance structural stability and optimize airflow guidance effect. This airflow adjustment device is ingeniously designed; it can automatically or manually switch to the most suitable state according to different driving conditions, thereby optimizing the vehicle's aerodynamic performance. Specifically, this design can improve vehicle stability when cornering, while reducing wind resistance and improving range and acceleration performance when driving straight.
[0050] In some embodiments, see Figure 3 The drive mechanism 3 includes a motor 5, a gear 6, and a rack 7. In this design, the motor 5 drives the gear 6 to rotate, the gear 6 drives the rack 7 to move, and the rack 7 drives the first guide structure 1 and / or the second guide structure 2 to move. This design achieves high-precision displacement control through the gear and rack transmission mechanism, ensuring the motion stability of the guide structures. The drive mechanism 3 is not limited to using a gear and rack; worm gears, lead screws, or linkage mechanisms can be used instead. In some embodiments, the motor 5 is mounted on the subframe. This design effectively saves installation space by integrating the drive components into the subframe, while also facilitating maintenance and replacement. In some embodiments, the first guide structure 1 and the second guide structure 2 rotate within a range of 5°-20° along the rotating shaft 4. This design, by limiting the rotation range, satisfies functional requirements while avoiding structural interference.
[0051] In some embodiments, see Figure 3The first flow guiding structure 1 includes a first flat plate 8, and the second flow guiding structure 2 includes a second flat plate 9. The included angle between the first flat plate 8 and the second flat plate 9 is 5°-20°. This design allows for switching between different aerodynamic performances by adjusting the tilt angle of the flat plate structures. In some embodiments, the first flow guiding structure 1 further includes a first back plate 11, and the second flow guiding structure 2 further includes a second surrounding plate 12 and a second back plate 13. The second surrounding plate 12 and the second back plate 13 are connected to form a closed cavity. This design, through the setting of the closed cavity, can effectively eliminate airflow gaps between the flow guiding structure and surrounding components, thereby improving aerodynamic efficiency. In some embodiments, the length of the first flat plate 8 along the first direction ranges from 150-300 mm, and the length along the second direction ranges from 150-300 mm. The height of the first back plate 11 in the third direction is set so that the first flow guiding structure 1 can form a seal with the surrounding components. This design, through optimized dimensional parameter design, ensures the sealing and functionality of the structure.
[0052] In some embodiments, the length of the second plate 9 along the first direction ranges from 150-400 mm, and the length along the second direction ranges from 100-200 mm. The height of the second back plate 13 in the third direction is set so that the second airflow guiding structure 2 can form a seal with the surrounding components. The size and angle of the first plate 8 and the second plate 9 can be adjusted as needed to adapt to different driving conditions. This solution meets the aerodynamic requirements under different working conditions through differentiated size design. In some embodiments, the airflow regulating device is disposed on the subframe mudguard 105. This solution avoids interference with the vehicle chassis structure through reasonable layout. In some embodiments, the airflow regulating device is disposed in front of the wheel mudguard 106. This solution improves the airflow guiding efficiency by optimizing the installation position.
[0053] This application provides two operating states for the airflow regulating device: see Figures 1-7State 1 (Diffuser Mode): The first airflow guide structure 1 is tilted upwards, and the second flat plate 9 is flush with the subframe mudguard 105. In this state, the first airflow guide structure 1 forms a diffuser, which helps to increase the vehicle's downforce, thereby improving cornering stability. The second airflow guide structure 2 does not affect the flow of surrounding airflow, that is, it does not have a guiding effect. The first airflow guide structure 1, due to its concavity, forms a channel that gradually widens upwards, acting as a diffuser. When high-speed airflow flows into the first airflow guide structure 1 from the flat space under the vehicle, the airflow adheres to the first flat plate 8 and enters the gradually widening section, passing obliquely upwards along the first flat plate 8. Because the outlet is located inside the wheel, there is enough space for the airflow to wash upwards, which will not have a negative impact on the effect of the first airflow guide structure 1. The throat of the first airflow guide structure 1 forms a low-pressure area, attracting nearby airflow to accelerate towards the first airflow guide structure 1, which reduces the pressure near the front of the first airflow guide structure 1, increases the downforce (negative lift) of the vehicle's front axle, and can effectively improve the vehicle's driving stability and cornering speed. State 2 (Bladder Mode): The second airflow guiding structure 2 descends, and the first flat plate 8 is flush with the subframe mudguard 105. At this time, because the first flat plate 8 is flush with the subframe mudguard 105, the first airflow guiding structure 1 does not affect the surrounding airflow, i.e., it does not have a guiding effect. The second airflow guiding structure 2 then bulges downwards, acting as a bladder. When airflow flows into the bottom of the bumper, the second airflow guiding structure 2 blocks the wheels, effectively reducing the positive pressure zone on the wheel's frontal surface and reducing the airflow entering the wheel cavity, thereby reducing overall vehicle drag and improving the vehicle's range, straight-line acceleration, and top speed performance. In this state, the second airflow guiding structure 2 acts as a bladder, reducing wheel drag and thus improving range and straight-line acceleration performance. This airflow adjustment device can be switched between manual and automatic control. Automatic control includes racing mode and normal mode; Racing mode: automatically switches the state of the airflow structure based on signals such as vehicle speed, steering wheel angle, and braking from sensors; Normal mode: automatically switches the state of the airflow structure based on vehicle speed. When the vehicle speed is below 20 kph, it switches to state 1; when the vehicle speed is above 100 kph, it switches to state 1; and at other speeds, it switches to state 2.
[0054] This application also provides a control method for an airflow regulating device. See [link to relevant documentation]. Figure 8The method includes: the airflow regulating device having at least a first state and a second state; the first state is that the first guide structure 1 rises, and the second plate 9 is flush with the subframe mudguard 105; the second state is that the second guide structure 2 descends, and the first plate 8 is flush with the subframe mudguard 105. The first guide structure 1 and the second guide structure 2 are driven to rotate around the pivot 4 by a drive mechanism 3, thereby switching between diffuser mode and baffle mode. In some embodiments, mode switching is based on vehicle speed, and this scheme achieves automatic control through speed threshold judgment. In some embodiments, mode switching is based on driving state, and this scheme optimizes aerodynamic performance through parameters such as steering angle and acceleration. In some embodiments, mode switching is based on road condition information, and this scheme acquires environmental data through radar or a camera to dynamically adjust the state of the guide structure.
[0055] This application also provides an aerodynamic performance optimization scheme. Through the coordinated movement of the first guide structure 1 and the second guide structure 2, it achieves a 12ct reduction in drag coefficient and a 55ct increase in lift coefficient (state 1), or a 60ct reduction in lift coefficient and a 13ct increase in drag coefficient (state 2). This scheme is verified through simulation and wind tunnel testing, ensuring performance optimization under different operating conditions. In some embodiments, the motion trajectory of the guide structure is optimized through CAD modeling; this scheme improves design accuracy through digital twin technology. In some embodiments, lightweight composite materials are used for the structure; this scheme improves vehicle energy efficiency through weight reduction. In some embodiments, the control logic of the drive mechanism 3 is optimized through AI algorithms; this scheme achieves adaptive control through machine learning.
[0056] In some embodiments, see Figure 8 The vehicle has a racing mode and a normal mode. In racing mode, if the vehicle speed exceeds 300 kph, the steering wheel angle is less than 40°, or a braking signal is received, the airflow adjustment device switches to the first state; otherwise, it switches to the second state. In normal mode, if the vehicle speed is greater than 20 kph but less than 100 kph, the airflow adjustment device switches to the second state; otherwise, it switches to the first state. This solution achieves precise mode switching through multi-parameter logical judgment.

This vehicle, by integrating an airflow regulation device, significantly improves aerodynamic performance, reduces energy consumption, and enhances handling stability.
[0061] In some embodiments, the vehicle collects parameters such as speed and handling status in real time through sensors, enabling automatic switching via data-driven mechanisms. In some embodiments, the vehicle control system dynamically adjusts the angle of the guide structure based on wind tunnel test data, optimizing the control strategy through simulation results. In some embodiments, the vehicle achieves rapid response through an electric drive mechanism, ensuring structural motion stability through the high torque output of motor 5. In some embodiments, the vehicle employs a modular design to facilitate the replacement and maintenance of the guide structure, improving system maintainability through standardized interface design.
