[0014] The step of controlling the air deflector to enter air deflection mode when the vehicle is at high speed, so as to reduce the drag on the vehicle through the air deflector, specifically includes:

[0015] Based on the current vehicle speed, control the rotation of the first part to adjust the first part to a preset angle;

[0016] Wherein, when the angle of the first part is the preset angle, the first part can cause the airflow passing through the first part to move away from the vehicle.

[0017] In one embodiment, the step of determining the vehicle's driving status based on the current vehicle speed specifically includes:

[0018] When the current vehicle speed is less than 20 km / h, the vehicle is in the low-speed state;

[0019] When the current vehicle speed is greater than or equal to 20 km / h and less than or equal to 50 km / h, the vehicle is in the high-speed state.

[0020] In one embodiment, the step of determining the vehicle's driving state based on the current vehicle speed further includes:

[0021] When the current vehicle speed is greater than 50 km / h, the vehicle is in an ultra-high speed state.

[0022] In one embodiment, the fairing includes a first part, a third part, and a second part stacked sequentially from the outside to the inside. The windward side of the first part is rotatably mounted on the top of the vehicle about an axis in a first direction. The third part is movably mounted inside the first part in a direction from the windward side of the first part to the leeward side of the first part.

[0023] The step of stating that the vehicle is in a high-speed state when the current vehicle speed is greater than 50 km / h further includes:

[0024] Control the rotation of the first part to raise the leeward side of the first part to its maximum height, and control the third part to move in a direction away from the first part.

[0025] According to a second aspect of this application, a control device is also provided, the control device including a memory, a processor, and a control program for a flow guiding device stored in the memory and executable on the processor, the control program for the flow guiding device being configured to implement the steps of the control method for the flow guiding device as described above.

[0026] According to a third aspect of this application, a flow guiding device is also provided, the flow guiding device comprising:

[0033] In one embodiment, the sensing device further includes a height sensor electrically connected to the control device, the height sensor being used to sense the height of the vehicle.

[0034] In the technical solution of this application, when the vehicle is at low speed, the wind resistance is relatively small, and reducing wind resistance at this time does not significantly improve the vehicle's performance. Therefore, the vehicle can control the aerodynamic device to enter energy storage mode, prioritizing the conversion of solar energy through solar panels to store electrical energy for the vehicle or the aerodynamic device. When the vehicle is at high speed, the wind resistance due to driving is large, and reducing wind resistance at this time can significantly improve the vehicle's fuel economy. Therefore, the aerodynamic device can be controlled to enter a deflection mode, allowing the aerodynamic device to reduce wind resistance during vehicle operation through the deflector, thereby improving the vehicle's fuel economy. The aerodynamic device can also convert solar energy into electrical energy through solar panels, thereby saving the vehicle's energy consumption, or use the electrical energy converted from solar panels to drive the deflector's movement, thereby further improving the vehicle's fuel economy.

[0043] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0044] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0045] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0049] Some vehicles are equipped with aerodynamic deflectors on their roofs to reduce wind resistance during driving. In practical applications, the required height of the deflector varies depending on the vehicle's speed and cabin height. Therefore, traditional deflectors adjust their angle and height by rotating the deflector fairing, ensuring the fairing height corresponds to the vehicle's current speed and cabin height. However, traditional deflectors consume additional energy during adjustment, placing a significant burden on the vehicle.

[0050] In view of this, this application proposes a control method, control device and a guide device for a flow guiding device, which aims to solve the problem that traditional flow guiding devices generate additional energy consumption when adjusting the flow guiding fairing, thus placing a heavy burden on the vehicle. Figures 1 to 3 This is a schematic diagram of an embodiment of the flow guiding device proposed in this application.

[0051] The air deflector 100 proposed in this application includes a fairing 1, a solar module, a sensing device, and a control device. The fairing 1 is mounted on the top of the vehicle. The solar module includes a solar panel 2 and a battery connected to each other, and the solar panel 2 is mounted on the top of the fairing 1. The sensing device is mounted on the vehicle and includes a vehicle speed sensor for sensing the current vehicle speed. The control device is connected to the fairing 1 and the vehicle speed sensor, respectively.

[0052] In the technical solution of this application, when the vehicle is at low speed, the wind resistance is relatively small, and reducing wind resistance at this time does not significantly help the vehicle. Therefore, the vehicle can control the aerodynamic device 100 to enter the energy storage mode, prioritizing the conversion of solar energy through the solar panel 2 to store electrical energy for the vehicle or the aerodynamic device 100. At high speed, the vehicle experiences greater wind resistance due to driving. Reducing wind resistance at this time can significantly improve the vehicle's fuel economy. Therefore, the vehicle can prioritize reducing the resistance through the fairing 1, improving fuel economy. Thus, the aerodynamic device 100 can be controlled to enter the aerodynamic mode, allowing it to reduce wind resistance through the fairing 1, thereby improving fuel economy. The aerodynamic device 100 can also convert solar energy into electrical energy through the solar panel 2, thereby saving energy consumption, or use the electrical energy converted from the solar panel 2 to drive the fairing 1, further improving fuel economy.

[0053] In some embodiments, the fairing 1 includes a first portion 11, a third portion 13, and a second portion 12 stacked sequentially from the outside to the inside. The windward side of the first portion 11 is rotatably mounted on the top of the vehicle about an axis in a first direction M, and the second portion 12 is fixedly mounted on the top of the vehicle. The third portion 13 is movably mounted within the first portion 11 in a direction pointing from the windward side of the first portion 11 to the leeward side of the first portion 11. The fairing device 100 also includes a drive device, which is connected to the first portion 11, the third portion 13, the battery, and the control device, respectively.

[0054] A third part 13 is provided between the first part 11 and the second part 12 of the fairing 1, and the third part 13 is movably installed within the first part 11. The air guiding device 100 can drive the first part 11 to rotate and also drive the third part 13 to move via a drive device. Therefore, when the vehicle is at high speed, the drive device can drive the first part 11 to rotate, thereby raising the leeward side of the first part 11 and improving the air guiding effect of the fairing 1. When the first part 11 rotates to the top dead center, the drive device can also drive the third part 13 to move, allowing the leeward side of the third part 13 to move out from within the first part 11, which is equivalent to extending the air guiding length of the first part 11, thereby further enhancing the air guiding effect of the fairing 1.

[0055] In practical applications, when a vehicle is traveling at high speeds, it experiences significant wind resistance. The drive unit can rotate the windward side of the first part 11 around an axis in the first direction M, causing the leeward side of the first part 11 to rise. This enhances the airflow guiding capacity of the fairing 1, thereby improving fuel economy. Furthermore, when the vehicle travels at higher speeds, the airflow guiding device 100 further enhances the airflow guiding effect of the fairing 1 by driving the movement of the third part 13, thus meeting the vehicle's airflow requirements and improving fuel economy.

[0056] When the vehicle is in motion, the airflow impacts the fairing 1, and the fairing 1 reduces the resistance generated by the airflow impact through its own structure. The fairing 1 should prevent airflow from entering the interior of the fairing 1, which would affect the fairing 1's airflow guiding effect. Therefore, in some embodiments, the sensing device also includes a seal that is sealed between the first part 11 and the second part 12, thereby preventing airflow from entering the interior of the fairing 1 from the first part 11 and the second part 12.

[0057] This application also proposes a control device, which is the same as the control device described in the above-mentioned flow guiding device 100. Figure 6 This is a schematic diagram of an embodiment of the control device proposed in this application. Please refer to... Figure 6 The control device may include a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen or an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wi-Fi interface). The memory 1005 may be high-speed RAM or non-volatile memory, such as a disk drive. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0058] In addition, this application also proposes a storage medium, which may be the memory 1005 in the control device as described above. The memory 1005 may include an operating system, a network communication module, a user interface module, and the steps of the control method of the diversion device 100 as described below.

[0059] Based on the above hardware structure, the present invention proposes a control method for the flow guiding device 100. Figures 4 to 5 This is a schematic flowchart illustrating the control method for the air deflector 100 proposed in this application. The air deflector 100 includes a fairing 1 mounted on the top of the vehicle and a solar panel 2 disposed on top of the fairing 1. Please refer to [link / reference]. Figure 4 The control methods include:

[0060] S10: Get the vehicle's current speed.

[0061] S20: Determine the vehicle's driving status based on the current speed.

[0062] S30: When the vehicle is at a low speed, the control flow device 100 enters the energy storage mode to store solar energy through the solar panel 2.

[0063] S40: When the vehicle is at high speed, the flow guide device 100 is controlled to enter the flow guide mode to reduce the resistance experienced by the vehicle through the flow guide 1.

[0064] In the technical solution of this application, when the vehicle is at low speed, the wind resistance is relatively small, and reducing wind resistance at this time does not significantly help the vehicle. Therefore, the vehicle can control the aerodynamic device 100 to enter the energy storage mode, prioritizing the conversion of solar energy through the solar panel 2 to store electrical energy for the vehicle or the aerodynamic device 100. At high speed, the vehicle experiences greater wind resistance due to driving. Reducing wind resistance at this time can significantly improve the vehicle's fuel economy. Therefore, the vehicle can prioritize reducing the resistance through the fairing 1, improving fuel economy. Thus, the aerodynamic device 100 can be controlled to enter the aerodynamic mode, allowing it to reduce wind resistance through the fairing 1, thereby improving fuel economy. The aerodynamic device 100 can also convert solar energy into electrical energy through the solar panel 2, thereby saving energy consumption, or use the electrical energy converted from the solar panel 2 to drive the fairing 1, further improving fuel economy.

[0065] It should be noted that the aerodynamic guide device 100 can simultaneously store solar energy through the solar panel 2 and reduce vehicle drag through the deflector 1. When the aerodynamic guide device 100 is in aerodynamic mode, the solar panel 2 can also convert and store solar energy. However, when the aerodynamic guide device 100 is in energy storage mode, the energy storage effect of the solar panel 2 should be prioritized when the first part 11 is rotated to adjust its angle, resulting in higher solar energy conversion efficiency. Conversely, when the aerodynamic guide device 100 is in aerodynamic mode, the aerodynamic effect of the deflector 1 should be prioritized when the first part 11 is rotated to adjust its angle, resulting in better aerodynamic effect of the deflector 1, while the solar energy conversion efficiency is relatively average.

[0066] In some embodiments, the fairing 1 includes a first portion 11 and a second portion 12 stacked sequentially from the outside to the inside, wherein the windward side of the first portion 11 is configured to be rotatable about an axis in a first direction M.

[0067] Step S30 specifically includes:

[0068] S31. Control the first part 11 to rotate so that the orientation of the solar panel 2 corresponds to the current direction of sunlight. When the first part 11 rotates, the angle of the solar panel 2 located on the side of the first part 11 away from the vehicle will change accordingly. Therefore, controlling the rotation of the first part 11 can adjust the orientation of the solar panel 2, thereby improving the solar energy conversion efficiency of the solar panel 2.

[0069] In some embodiments, the fairing 1 includes a first part 11 and a second part 12 stacked sequentially from the outside to the inside. The windward side of the first part 11 is configured to be rotatable about an axis in a first direction M, so that the leeward side of the first part 11 can rise and move away from the second part 12.

[0070] Step S40 specifically includes:

[0071] S41. Based on the current vehicle speed, control the first part 11 to rotate, so as to adjust the first part 11 to a preset angle;

[0072] When the angle of the first part 11 is a preset angle, the first part 11 can make the airflow passing through the first part 11 move away from the vehicle.

[0073] When the angle of the first part 11 is a preset angle, the first part 11 can keep the airflow passing through it away from the vehicle, reducing the airflow that comes into contact with the vehicle, thereby reducing the air resistance generated by the airflow on the vehicle. The preset angle of the airflow guide device 100 is actually a range of angle values, and when the angle of the first part 11 is the minimum value of the preset angle, the airflow passing through the first part 11 will not come into contact with the vehicle again, while the maximum value is the top dead center of the first part 11 during rotation. According to the current vehicle speed, the rotation of the first part 11 is controlled so that the angle of the first part 11 can meet the drag reduction requirements of the vehicle at the current speed.

[0074] In some embodiments, please refer to Figure 5 Step S20 specifically includes:

[0075] S21: When the current vehicle speed is less than 20 km / h, the vehicle is in a low-speed state. When the current vehicle speed is less than 20 km / h, the vehicle experiences less wind resistance, so the vehicle does not need the air deflector 100 to reduce wind resistance. Therefore, the vehicle can be determined to be in a low-speed state at this time, and the air deflector 100 prioritizes converting solar energy through the solar panel 2.

[0076] S22: When the current vehicle speed is greater than or equal to 20 km / h and less than or equal to 50 km / h, the vehicle is in a high-speed state. When the current vehicle speed is greater than or equal to 20 km / h and less than or equal to 50 km / h, the vehicle experiences significant wind resistance. Therefore, the vehicle needs the air deflector 100 to reduce wind resistance. Thus, the vehicle can be determined to be in a high-speed state at this time. The air deflector 100 prioritizes reducing the wind resistance experienced by the vehicle through the air deflector 1.

[0077] In some embodiments, step S20 further includes:

[0078] S23: When the current vehicle speed is greater than 50 km / h, the vehicle is in an ultra-high speed state. When the current vehicle speed is greater than 50 km / h, the vehicle experiences significant wind resistance. Therefore, the vehicle needs a deflector device to reduce wind resistance to a large extent, and the vehicle can be determined to be in an ultra-high speed state at this time.

[0079] In some embodiments, the fairing 1 includes a first part 11, a third part 13, and a second part 12 stacked sequentially from the outside to the inside. The windward side of the first part 11 is rotatably mounted on the top of the vehicle about an axis in a first direction M. The third part 13 is movably mounted within the first part 11 in a direction pointing from the windward side of the first part 11 to the leeward side of the first part 11.

[0080] Step S23 is followed by:

[0081] S32. Control the rotation of the first part 11 to raise the leeward side of the first part 11 to its maximum height, and control the movement of the third part 13 in a direction away from the first part 11. A third part 13 is also provided between the first part 11 and the second part 12 of the fairing 1, and the third part 13 is movably installed within the first part 11. The guide device 100 can drive the first part 11 to rotate and also drive the third part 13 to move via a drive device. In practical applications, when the vehicle is at high speed, the wind resistance is greater. The drive device can drive the windward side of the first part 11 to rotate around the axis in the first direction M, thereby raising the leeward side of the first part 11 and enhancing the guiding capacity of the fairing 1, thus improving fuel economy. When the vehicle speed is higher, the guide device 100 further enhances the guiding effect of the fairing 1 by driving the movement of the third part 13, thereby meeting the vehicle's guiding needs and improving fuel economy.

[0082] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
