[0066] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0067] The following will refer to Figure 1-Figure 7 A wind guide structure 10, a wheel housing 100 and a vehicle 1000 are described according to some embodiments of the present invention.

[0068] refer to Figure 1-Figure 4 An embodiment of the first aspect of the present invention provides an air guide structure 10, which is used for a wheel cover 100 of a vehicle 1000. The air guide structure 10 includes an air guide component 1 and a drive component 2. The drive component 2 is connected to the air guide component 1, and the drive component 2 is used to drive the air guide component 1 to move relative to the wheel cover 100.

[0069] Optionally, the drive component 2 is used to drive the air guide component 1 to rotate relative to the wheel cover 100, so that the air outlet angle of the air guide component 1 relative to the wheel cover 100 can be changed, so as to reduce or avoid the airflow flowing through the air guide structure 10 directly blowing on the wheel 30; optionally, the drive component 2 can also be used to drive the air guide component 1 to move relative to the wheel cover 100, so that the airflow outlet of the air guide component 1 is staggered by a certain distance from the wheel 30, so as to reduce or avoid the airflow flowing through the air guide structure 10 directly blowing on the wheel 30.

[0070] Optionally, the air guide structure 10 may have one or more air flow channels, each of which has air flow openings connected thereto, one of which is an air flow inlet and the other is an air flow outlet, and the air flow outlet is located on a side close to the wheel 30 along the thickness direction of the wheel cover 100 .

[0071] For example, when the vehicle 1000 is traveling at high speed, the driving component 2 can move the wind guide component 1 to a position that is more conducive to reducing wind resistance, thereby helping to improve the power economy of the vehicle 1000.

[0072] The air guide component 1 has a self-cleaning effect when it moves relative to the wheel cover 100, which can reduce the adhesion of mud and sand and keep the air flow channel of the air guide component 1 unobstructed.

[0073] According to the wind guide structure 10 of the embodiment of the present invention, by providing a driving component 2 connected to the wind guide component 1, the driving component 2 drives the wind guide component 1 to move relative to the wheel cover 100, which can reduce or prevent the airflow flowing through the wind guide structure 10 from directly blowing on the wheel 30, thereby reducing the wind resistance to the wheel 30. In this way, during the operation of the wind guide structure 10, in addition to having a heat dissipation effect, the wind guide structure 10 can also reduce the wind resistance generated by the airflow flowing through the wind guide structure 10 according to the requirements of different working states of the vehicle 1000, so as to improve the power economy of the vehicle 1000.

[0074] refer to Figure 1-Figure 4 In some embodiments, the air guide assembly 1 includes a plurality of air guide components, and at least two of the air guide components extend in different directions.

[0075] Among them, the extension directions of at least two of the air guide components are different, which may include the following situations: for example, the extension directions of the two air guide components of the air guide assembly 1 are different; for another example, the extension directions of any two air guide components among the multiple air guide components are different.

[0076] By making at least two air guide components extend in different directions, the air guide components with different extension directions can more effectively guide the airflow from multiple angles, so that during the activity of the air guide assembly 1, the airflow change angles of the entire air guide assembly 1 are also more, which is conducive to further enriching the working mode of the air guide assembly 1, so as to better meet the needs of different working states of the vehicle 1000. At the same time, it can also avoid the local air pressure imbalance that may be caused by airflow guidance in a single direction.

[0077] In addition, the airflow can be guided to different positions of the vehicle 1000 by the air guide components extending in different directions, for example, the airflow can be guided to key parts that need heat dissipation, such as the engine compartment and the brake system, to improve the cooling efficiency of these areas and ensure that the vehicle 1000 can maintain a good operating temperature even in a high-performance state. The coordinated airflow guiding effect of the grille blades 11 that do not extend in the direction can significantly reduce the energy loss of the airflow, improve the airflow efficiency of the air guide structure 10, and then increase the gas flow and enhance the heat dissipation effect.

[0078] refer to Figure 1-Figure 4In some embodiments, each air guide component includes a group of grille blades 11, and the air guide component includes a first air guide component 12 and a second air guide component 13. The grille blades 11 of the first air guide component 12 and the grille blades 11 of the second air guide component 13 extend in different directions. By making each air guide component include a group of grille blades 11, the grille blades 11 allow for more precise control of the direction and speed of the airflow, and the grille blades 11 with different extension directions can guide the airflow toward different target areas respectively.

[0079] The driving assembly 2 can drive the grille blades 11 of the air guide component to rotate relative to the wheel cover 100 to change the outlet angle of the airflow flowing through the air guide assembly 1.

[0080] refer to Figure 1-Figure 4 In some embodiments, the air guide assembly 1 includes grille blades 11, and two adjacent grille blades 11 define an airflow channel for airflow to pass through. The driving assembly 2 is used to drive the grille blades 11 to rotate to a variety of different angles to change the airflow direction through the airflow port.

[0081] Among them, it needs to be explained that the grille blade 11 of the air guide assembly 1 has an initial position, and the grille blade 11 rotates to a plurality of different angles, which means that the grille blade 11 can rotate to a plurality of different positions, and the angles between the plurality of different positions and the initial position are different, that is, the grille blade 11 has a plurality of different working positions, and the angles between the different working positions and the initial position are different.

[0082] Optionally, all grille blades 11 of the air guide assembly 1 are rotatable; optionally, part of the grille blades 11 of the air guide assembly 1 are rotatable, while another part of the grille blades 11 are fixed to the wheel cover 100 .

[0083] By making the air guide component 1 include grille blades 11, the grille blades 11 can achieve more flexible airflow control, and by adjusting the angle of the grille blades 11 through the driving component 2, the direction and speed of the airflow can be flexibly controlled to meet the needs of different working conditions of the vehicle 1000.

[0084] refer to Figure 1-Figure 4 In some embodiments, the air guide assembly 1 includes multiple air guide components, and the grille blades 11 are divided into multiple groups. Each air guide component includes a group of grille blades 11, and each group of grille blades 11 includes multiple grille blades 11. At least two groups of grille blades 11 have different extension directions.

[0085] The extension directions of at least two groups of grille blades 11 are different, which may include the following situations: for example, the extension directions of two groups of grille blades 11 in the multiple groups of grille blades 11 are different; for another example, the extension directions of any two groups of grille blades 11 in the multiple groups of grille blades 11 are different.

[0086] By making at least two groups of grille blades 11 extend in different directions, the grille blades 11 with different extension directions can more effectively guide the airflow from multiple angles, so that during the activity of the air guide assembly 1, the airflow change angles of the entire air guide assembly 1 are also more, which is conducive to further enriching the working mode of the air guide assembly 1, so as to better meet the needs of different working states of the vehicle 1000. At the same time, it can also avoid the local air pressure imbalance that may be caused by airflow guidance in a single direction.

[0087] In addition, the grille blades 11 extending in different directions can guide the airflow to different locations of the vehicle 1000, for example, the airflow can be guided to key locations that require heat dissipation, such as the engine compartment and the brake system, to improve the cooling efficiency of these areas and ensure that the vehicle 1000 can maintain a good operating temperature even in a high-performance state. The coordinated flow-guiding effect of the grille blades 11 not extending in the same direction can significantly reduce the energy loss of the airflow, improve the airflow efficiency of the air guide structure 10, and thus increase the gas flow rate and enhance the heat dissipation effect.

[0088] refer to Figure 1-Figure 4 In some embodiments, the plurality of air guide components include a first air guide component 12. In a first direction (as shown in the direction e1 in the figure), the first air guide component 12 has a first end and a second end. The first end is adapted to be closer to the outside of the wheel cover 100 than the second end. The grille blades 11 of the first air guide component 12 extend obliquely from the first end to the second end. By making the grille blades 11 extend obliquely from the first end to the second end, the first air guide component 12 has a guiding effect on the airflow in the second direction (as shown in the direction e2 in the figure), so that the airflow can leave the wheel cover 100 more smoothly. In this way, during the rotation of the grille blades 11, the airflow directly blowing the wheel 30 from the bottom of the vehicle can be further reduced.

[0089] When the air guide structure 10 is applied to the vehicle 1000 , the first direction is consistent with the width direction of the vehicle 1000 , and the second direction is consistent with the height direction of the vehicle 1000 .

[0090] refer to Figure 1-Figure 4 In some embodiments, the plurality of air guide components include a first air guide component 12 and a second air guide component 13 arranged along a first direction, and the grille blades 11 of the first air guide component 12 and the grille blades 11 of the second air guide component 13 extend in different directions. By arranging the first air guide component 12 and the second air guide component 13 along the first direction, the airflow passing through the air guide structure 10 can be more evenly distributed along the first direction, avoiding the airflow from being concentrated on one side, thereby reducing the turbulence and vortex formation of the local airflow.

[0091] refer to Figure 1-Figure 4In some embodiments, in the first direction, the first air guide component 12 has a first end and a second end, the first end is adapted to be closer to the outside of the wheel cover 100 than the second end, and the grille blades 11 of the first air guide component 12 extend downwardly and obliquely in the direction from the first end to the second end. By making the grille blades 11 of the first air guide component 12 extend downwardly and obliquely in the direction from the first end to the second end, the first air guide component 12 has a guiding effect on the airflow in the second direction, so that the airflow can leave the wheel cover 100 more smoothly. In addition, during the rotation of the grille blades 11, the airflow can be guided toward the outside of the wheel cover 100, which can further reduce the airflow directly blowing the wheel 30 from the bottom of the vehicle.

[0092] refer to Figure 1-Figure 4 In some embodiments, the grille blades 11 of the second air guide member 13 extend along the second direction, wherein the first direction intersects the second direction. By extending the second air guide member 13 along the second direction, the second air guide member 13 can guide the airflow along the first direction during the rotation of the second air guide member 13, so as to guide the airflow to an area close to the inside or outside of the vehicle 1000.

[0093] refer to Figure 1-Figure 4 In some embodiments, the extension direction of the rotation axis of the grille blades 11 of the first air guide component 12 is the first axial direction, and the extension direction of the grille blades 11 of the first air guide component 12 is consistent with the first axial direction. The extension direction of the rotation axis of the grille blades 11 of the second air guide component 13 is the second axial direction, and the extension direction of the grille blades 11 of the second air guide component 13 is consistent with the second axial direction. By making the extension direction of the grille blades 11 of the first air guide component 12 consistent with the first axial direction, and making the extension direction of the grille blades 11 of the second air guide component 13 consistent with the second axial direction, it is helpful to simplify the structure of the first air guide component 12 and the second air guide component 13, reduce the complexity of design and manufacturing, and reduce the production cost; in addition, such a setting also makes the rotation of the first air guide component 12 and the second air guide component 13 smoother, the airflow can pass through the airflow channel more smoothly, reduce the turbulence and vortex formation of the airflow, and improve the efficiency of airflow management.

[0094] refer to Figure 1-Figure 4 In some embodiments, in a first direction, the grille blades 11 of the first air guide component 12 are adapted to be close to the outside of the wheel cover 100, and the driving assembly 2 is adapted to drive the grille blades 11 of the first air guide component 12 to rotate to a plurality of different angles toward the bottom of the vehicle 1000. By rotating the grille blades 11 of the first air guide component 12 toward the bottom of the vehicle 1000, the airflow can be effectively guided from the outside of the wheel cover 100 to the bottom, which helps to optimize the airflow path, effectively reduce the air resistance around the wheel 30, and improve the overall aerodynamic performance of the vehicle 1000, thereby facilitating the improvement of the power economy of the vehicle 1000.

[0095] refer to Figure 1-Figure 4 In some embodiments, in the first direction, the grille blades 11 of the second air guide component 13 are adapted to be close to the inner side of the wheel cover 100, and the driving assembly 2 is adapted to drive the grille blades 11 of the second air guide component 13 to rotate to a plurality of different angles toward the inner side of the vehicle 1000. By rotating the grille blades 11 of the second air guide component 13 toward the inner side of the vehicle 1000, the airflow can be more effectively guided to key components that require heat dissipation, such as brakes or brake discs, while also preventing the airflow from directly blowing the tires.

[0096] refer to Figure 2-Figure 5 In some embodiments, the air guide component includes a connecting rod 3, each group of grille blades 11 is connected to the connecting rod 3, the driving assembly 2 is connected to the connecting rod 3, and the driving assembly 2 drives the connecting rod 3 to perform linear motion along the extension direction of the connecting rod 3 to drive the grille blades 11 to rotate. By setting the connecting rod 3, the connecting rod 3 transmits the power of the driving assembly 2 to the grille blades 11 so that the connecting rod 3 can simultaneously drive multiple grille blades 11 to rotate, which is conducive to simplifying the structural setting of the air guide structure 10, and it is no longer necessary to drive multiple grille blades 11 separately; in addition, the linear motion of the connecting rod 3 can accurately control the rotation angle of the grille blade 11, thereby achieving fine adjustment of the airflow direction and speed, and can also ensure that the grille blade 11 transitions smoothly during the rotation process, and can also ensure the consistency of the angle adjustment of each blade, reducing the turbulence of the airflow and the formation of vortices.

[0097] In some embodiments, the connecting rod 3 includes a first connecting rod 3 and a second connecting rod 3 , the first connecting rod 3 and the second connecting rod 3 have different extension directions, the first connecting rod 3 is connected to the grille blades 11 of the first air guide component 12 , and the second connecting rod 3 is connected to the grille blades 11 of the second air guide component 13 .

[0103] refer to Figure 1 An embodiment of the second aspect of the present invention provides a wheel cover 100, including the above-mentioned wind guide structure 10.

[0104] According to the wheel cover 100 of the embodiment of the present invention, by providing the above-mentioned wind guide structure 10, the wheel cover 100 not only has the heat dissipation effect but also can reduce the wind resistance generated by the airflow flowing through the wind guide structure 10 according to the requirements of different working states of the vehicle 1000, so as to improve the power economy of the vehicle 1000.

[0105] refer to Figure 1 In some embodiments, the wheel cover 100 further includes a cover body 20, and the air guide structure 10 is disposed on the cover body 20. The cover body 20 of the wheel cover 100 can block water, mud and other debris splashed when the wheel 30 rotates, prevent these substances from splashing to other parts of the vehicle body, and protect the paint and vehicle body from damage.

[0106] refer to Figure 7 An embodiment of the third aspect of the present invention provides a vehicle 1000, including the wind guide structure 10 of the first aspect of the present invention or the wheel cover 100 of the second aspect of the present invention.

[0107] According to the vehicle 1000 of the embodiment of the present invention, by providing the above-mentioned wind guide structure 10 (not shown in the figure) or the wheel cover 100, according to the operating requirements of the vehicle 1000, it is possible to effectively dissipate the heat of the vehicle 1000 and reduce the wind resistance of the vehicle 1000, thereby improving the power economy of the vehicle 1000.

[0108] In some embodiments, the vehicle 1000 has multiple working states, and in different working states, the rotation angle of the air guide assembly 1 is different. The air guide assembly 1 can make a dynamic response according to the driving state of the vehicle 1000 to optimize the performance of the whole vehicle.

[0109] In some embodiments, the multiple working states include a first working state, in which the driving assembly 2 drives the grille blades 11 of the air guide assembly 1 to rotate to a second preset angle, the first preset angle being greater than or equal to 0° and less than or equal to 45°. By rotating the grille blades 11 of the air guide assembly 1 to the second preset angle, the grille has a larger ventilation area and airflow rate, so that the air guide structure 10 has an excellent heat dissipation effect.

[0110] Optionally, the first preset angle is greater than or equal to 0° and less than or equal to 30°.

[0111] In some embodiments, in the first working state, the temperature of the coolant of the vehicle 1000 exceeds a preset temperature value. By using the temperature of the coolant of the vehicle 1000 as the basis for adjusting the rotation angle of the air guide structure 10, timely and effective heat dissipation can be achieved when the temperature of the coolant of the vehicle 1000 exceeds the preset temperature value, thereby preventing the coolant from being in an over-temperature state and affecting the normal operation of the vehicle 1000.

[0112] For example, the coolant is ethylene glycol aqueous solution. For example, the preset temperature value is 70°C.

[0113] In some embodiments, the multiple working states include a second working state, in which the driving assembly 2 drives the grille blades 11 of the air guide assembly 1 to rotate to a fourth preset angle, the second preset angle being greater than or equal to 45° and less than or equal to 90°. By rotating the grille blades 11 of the air guide assembly 1 to the fourth preset angle, the airflow can smoothly bypass the wheel 30 through the guiding effect of the grille blades 11, reducing the wind resistance to the wheel 30, so as to improve the power economy of the vehicle 1000.

[0114] In some embodiments, the second preset angle is greater than or equal to 45° and less than or equal to 75°.

[0115] In some embodiments, in the second working state, the driving speed of the vehicle 1000 is higher than the preset speed value. By using the driving speed of the vehicle 1000 as the basis for adjusting the rotation angle of the wind guide structure 10, the wind guide assembly 1 can effectively reduce the wind resistance of the vehicle 1000 when the vehicle 1000 is driving at high speed.

[0116] For example, the preset speed value is 80 kph.

[0117] In some embodiments, in the second working state, the temperature of the coolant of the vehicle 1000 is lower than a preset temperature value.

[0118] In some embodiments, the multiple working states include a third working state, in which the driving assembly 2 drives the grille blades 11 of the air guide assembly 1 to rotate to a third preset angle, and the third preset angle is greater than or equal to 30° and less than or equal to 45°. By rotating the grille blades 11 of the air guide assembly 1 to the third preset angle, the air guide mechanism has a good air guide and heat dissipation effect and does not generate a large wind resistance on the vehicle 1000.

[0119] In some embodiments, in the third working state, the driving speed of the vehicle 1000 is greater than 0 kph and lower than a preset speed value.

[0120] In some embodiments, in the third working state, the temperature of the coolant of the vehicle 1000 is lower than a preset temperature value.

[0121] In some embodiments, the multiple working states include a fourth working state, in which the driving assembly 2 drives the grille blades 11 of the air guide assembly 1 to rotate to a first preset angle, and the fourth preset angle is greater than or equal to 75° and less than or equal to 90°. By rotating the grille blades 11 of the air guide assembly 1 to the first preset angle, the grille blades 11 are approximately in a closed state, which can prevent dust or small animals from entering the engine compartment, and also help the engine of the vehicle 1000 to heat up after ignition.

[0122] In some embodiments, in the fourth working state, the driving speed of the vehicle 1000 is 0 kph, thus ensuring that the air guide assembly 1 is opened only when the vehicle 1000 is in driving state.

[0123] refer to Figure 2-Figure 4 In some embodiments, the air guide structure 10 has a plurality of different working modes according to the different requirements of the working state of the vehicle 1000. The plurality of working modes include a dormant mode, a high heat dissipation mode, a low wind resistance mode and a balanced mode. The air guide assembly 1 switches between different working modes by driving the grille blades 11 to rotate to different angles. In the dormant mode, the driving assembly 2 drives the grille blades 11 of the air guide assembly 1 to rotate to a first preset angle; in the high heat dissipation mode, the driving assembly 2 drives the grille blades 11 of the air guide assembly 1 to rotate to a second preset angle to prevent the coolant temperature of the vehicle 1000 from being in an over-temperature state for a long time; in the low wind resistance mode, the driving assembly 2 drives the grille blades 11 of the air guide assembly 1 to rotate to a fourth preset angle, which is beneficial to reducing the wind resistance of the vehicle 1000 and improving the power economy of the vehicle 1000; in the balanced mode, the driving assembly 2 drives the grille blades 11 of the air guide assembly 1 to rotate to a third preset angle. The air guide mechanism has a good wind guide and heat dissipation effect and does not generate a large wind resistance to the vehicle 1000.

[0124] In some embodiments, the vehicle 1000 further includes a heat dissipation component, the heat dissipation component and the air guide structure 10 are arranged along a third direction, and the air guide structure 10 is used to improve the heat dissipation effect of the heat dissipation component, wherein the first direction, the second direction and the third direction intersect each other. Optionally, the heat dissipation component is arranged in the engine compartment to dissipate heat from the engine.

[0125] Optionally, the heat dissipation component has heat dissipation gaps arranged along the first direction and along the second direction, and the air flow channel and the heat dissipation gaps of the second air guide component 13 are relative to each other along the third direction. This is conducive to increasing the air flow passing through the heat dissipation component and further improving the heat dissipation effect of the heat dissipation component.

[0126] An embodiment of the fourth aspect of the present invention provides an air guide control system for a vehicle 1000, wherein the vehicle 1000 has multiple working states, including: an air guide structure 10, which is the air guide structure 10 of the first aspect of the present invention; a monitoring module, which is used to monitor at least one of the startup state of the vehicle 1000, the coolant temperature of the vehicle 1000 and the driving speed of the vehicle 1000; and a control module, which is suitable for controlling the angle of the air guide assembly 1 according to the monitoring results of the monitoring module.

[0127] According to the wind guide control system of the embodiment of the present invention, it is possible to control the angle of the wind guide assembly 1 relative to the wheel cover 100 according to the requirements of different working states of the vehicle 1000, so as to adjust the heat dissipation effect and wind resistance reduction effect of the wind guide structure 10, so as to optimize the working effect of the wind guide structure 10.

[0129] According to the control method of the wind guide control system of the embodiment of the present invention, the working effect of the wind guide structure 10 can be optimized by controlling the wind guide assembly 1 to rotate to different angles according to the requirements of different working states of the vehicle 1000.

If the temperature of the coolant of the vehicle 1000 is not higher than the preset temperature value, executing the next step, if the temperature of the coolant of the vehicle 1000 is higher than the preset temperature value, the control module controls the air guide assembly 1 to rotate to a second preset angle; monitoring the driving speed of the vehicle 1000 to monitor whether the driving speed of the vehicle 1000 is higher than the preset speed value. If the driving speed of the vehicle 1000 is not higher than the preset speed value, the control module controls the air guide assembly 1 to rotate to a third preset angle, if the driving speed of the vehicle 1000 is higher than the preset speed value, the control module controls the air guide assembly 1 to rotate to a fourth preset angle.

[0131] For example, the control method of the air guide control system includes the following steps:

[0139] Through the above control method, the state of the vehicle 1000 can be monitored in real time, and the wind guide assembly 1 can be dynamically controlled, thereby achieving dynamic response of the wind guide assembly 1 under different working states of the vehicle 1000.
