[0001] This invention relates to the field of vehicle technology, and in particular to a flow guiding mechanism, a vehicle body, and a vehicle. Background Technology

[0002] With the development of the automotive industry, more and more people are paying attention to and loving the supercar category. Supercars are different from traditional models. The ultimate pursuit of power performance makes wind resistance and thermal management and heat dissipation two key factors that limit the power of supercar models.

[0003] Unlike conventional models, some sports cars have a rear-mounted engine structure, with the engine compartment located at the rear of the vehicle. Most models have additional air intakes and cooling vents on the side to meet the engine's air intake and cooling needs. However, the air intake configuration of existing models is fixed, making it difficult to flexibly adjust the air intake volume as needed, resulting in limited improvement in the power performance of sports cars. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention provides a flow guiding mechanism that can conveniently change the on / off state of the air intake and adjust the air intake volume.

[0005] The present invention also proposes a vehicle body having the above-mentioned airflow guiding mechanism.

[0006] The present invention also proposes a vehicle having the above-described body.

[0007] According to a first aspect of the present invention, a flow guiding mechanism is used for a vehicle body, wherein air intake ducts are respectively provided on both sides of the vehicle body along the width direction, the flow guiding mechanism comprising: a flow guiding member movably disposed in the air intake duct to open or close the air intake duct and adjust the flow area of ​​the air intake duct; and a driving member, the driving member being throttlely connected to the flow guiding member to drive the flow guiding member to move.

[0008] According to the air intake mechanism of the present invention, by movably arranging the air intake member in the air intake duct, the opening and closing state of the air intake duct and the air intake volume of the air intake duct can be easily changed as needed, so that the vehicle can cope with the power and heat dissipation requirements under different operating conditions, and can also meet the air intake flow field requirements of the vehicle's rear engine compartment under different low-speed and high-speed modes, and under different high-temperature and low-temperature environments, which is conducive to improving the driving experience of the vehicle.

[0009] According to some embodiments of the present invention, the air intake extends along the length direction of the vehicle, the guide is disposed at the front of the air intake, and the rotation axis of the guide is parallel to the width direction of the vehicle body.

[0010] According to some embodiments of the present invention, the air guide is formed as a guide plate, the air guide has a first guide surface and a second guide surface, the first guide surface is located above the second guide surface when the air guide is in a horizontal state, and the second guide surface is formed as a downwardly convex curved surface, so that the air pressure on the first guide surface side of the air intake is greater than the air pressure on the second guide surface side when the vehicle is moving.

[0011] Furthermore, the first guide surface is a plane, the second guide surface is an arc-shaped surface, the first guide surface and the second guide surface are smoothly connected, and in the air intake direction, the distance between the first guide surface and the second guide surface first increases and then decreases.

[0012] Furthermore, the position where the distance between the first guide surface and the second guide surface is the largest is located at a rearward position along the length direction of the guide component.

[0013] According to some embodiments of the present invention, multiple flow guides are provided, and the multiple flow guides are arranged in a vertical direction. The driving member includes multiple flow guides that correspond one-to-one with the flow guides, and the motion control of the multiple flow guides is independent of each other.

[0014] Furthermore, the flow guide is formed as a flow guide plate. In two adjacent flow guides in the vertical direction, the top end of the flow guide located on the lower side has a sealing recessed portion recessed along the thickness direction, and the bottom end of the flow guide located on the upper side has a sealing mating portion recessed along the thickness direction. When multiple flow guides close the air intake, the sealing recessed portion and the sealing mating portion abut against each other along the thickness direction of the flow guide.

[0015] In some embodiments, the driving member is a drive motor, and the driving member is located on one side of the guide member along the width direction of the vehicle body and is not in the airflow path of the air intake.

[0016] According to a second aspect of the invention, a vehicle body includes a flow guide mechanism as described in the first aspect of the invention.

[0017] According to the vehicle body of the present invention, the air intake duct opening and closing state and the air intake volume can be easily changed as needed through the air guide mechanism of the first aspect, so that the vehicle can cope with the power and heat dissipation requirements under different working conditions, and can also meet the air intake flow field requirements of the vehicle's rear engine compartment under different low-speed and high-speed modes, and different high-temperature and low-temperature environments, which is conducive to improving the driving experience of the vehicle.

[0018] The vehicle according to the third aspect of the invention includes the body according to the second aspect of the invention.

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following is for reference. Figures 1-5 A flow guiding mechanism 100 according to an embodiment of the first aspect of the present invention is described.

[0033] like Figure 1As shown, according to a first aspect embodiment of the present invention, a flow guide mechanism 100 is used for a vehicle body 1000, wherein the vehicle may be a sports car or other type of sedan, the vehicle has a rear-mounted power system, and air intake ducts 201 are respectively provided on both sides of the body 1000 along the width direction, the air intake ducts 201 facilitating air intake and heat dissipation for the power system. The flow guide mechanism 100 may include: a flow guide 1 and a drive member 2.

[0034] Specifically, the guide member 1 is movably disposed in the air intake duct 201. The guide member 1 can be used to open or close the air intake duct 201. Furthermore, when the air intake duct 201 is open, the guide member 1 can also be used to adjust the flow area of ​​the air intake duct 201, thereby adjusting the intake volume. The drive member 2 can be connected to the guide member 1 for transmission to drive the guide member 1 to move.

[0035] For example, the air intake 201 can be formed at the rearward position on both sides of the vehicle body 1000. The air intake 201 can extend approximately along the length direction (i.e., the longitudinal direction) of the vehicle. The guide member 1 can be formed in the shape of a plate. The movement of the guide member 1 can be sliding, such as sliding along the height direction of the air intake 201 or sliding along the width direction of the air intake 201. Alternatively, the movement of the guide member 1 can also be rotation, such as flipping around a vertical axis in a horizontal plane or rotating around a horizontal axis in a vertical plane. The drive member 2 can be selected according to different types of drive motors and installed at different positions on the vehicle body 1000, depending on the different movement forms of the guide member 1.

[0036] According to the embodiment of the present invention, the airflow guiding mechanism 100, by movably distributing the airflow guide 1 in the air intake duct 201, can conveniently change the opening and closing state of the air intake duct 201 and adjust the air intake volume of the air intake duct 201 as needed, so that the vehicle can cope with the power and heat dissipation requirements under different working conditions, and can also meet the airflow requirements of the vehicle's rear engine compartment under different low-speed and high-speed modes, and different high-temperature and low-temperature environments, which is beneficial to improving the driving experience of the vehicle.

[0037] According to some embodiments of the present invention, the air intake duct 201 extends along the length direction of the vehicle (e.g., the longitudinal direction of the vehicle). Here, the extension direction of the air intake duct 201 is not necessarily absolutely parallel to the length direction of the vehicle; there may be an included angle, for example, 0-30°. The guide member 1 is rotatably disposed at the front of the air intake duct 201. For example, the guide member 1 may be disposed at the front opening of the air intake duct 201, or at one-third of the length of the air intake duct 201 from front to rear. Specifically, the position of the guide member 1 within the air intake duct 201 can be reasonably selected as needed. The rotation axis of the guide member 1 is parallel to the width direction of the vehicle body 1000, that is, the guide member 1 can rotate around a horizontal axis in vertical space. This simplifies the movement of the guide member 1, making it easy to control. Furthermore, the placement of the guide member 1 at the front of the air intake duct 201 makes it easier to control the intake volume.

[0038] Furthermore, the rotation range of the guide element 1 is 0-180°. In other words, when the guide element 1 rotates around the horizontal axis in the vertical plane, the rotation stroke of the guide element 1 is 0-180°. When the guide element 1 rotates past 0°, it is in its original position, and the air intake duct 201 is closed. When the guide element 1 rotates past 180°, it closes the air intake duct 201 again. Compared with the state when it is in its original position, the positions of the two opposing surfaces of the guide element 1 in the extension direction of the air intake duct 201 are reversed. When the guide element 1 rotates to be parallel to the extension direction of the air intake duct 201, the airflow area of ​​the air intake duct 201 reaches its maximum. Optionally, the position of the guide element 1 when the airflow area of ​​the air intake duct 201 reaches its maximum can be reasonably selected according to the extension direction of the air intake duct 201.

[0039] Furthermore, the air intake duct 201 has a first state and a second state. In the first state, the guide member 1 closes the air intake duct 201. At this time, the guide member 1 can be perpendicular to the extension direction of the air intake duct 201. In the second state, the guide member 1 opens the air intake duct 201 and is suitable for adjusting the flow area of ​​the air intake duct 201. When the guide member 1 is parallel to the extension direction of the air intake duct 201, the flow area of ​​the air intake duct 201 is the largest. In this way, it is easier to control the rotation position of the guide member 1 and better adjust the intake volume.

[0040] According to some embodiments of the present invention, reference Figure 5 The air guide 1 is formed as a deflector plate, and the air guide 1 has a first deflector surface 11 and a second deflector surface 12, with the two ends of the first deflector surface 11 and the second deflector surface 12 connected respectively. When the air guide 1 is in a horizontal state, the first deflector surface 11 is located above the second deflector surface 12, and the second deflector surface 12 is formed as a downwardly convex curved surface. Thus, when air flows through the second deflector surface 12, the airflow area of ​​the air intake duct 201 on the side of the second deflector surface 12 is reduced, which increases the airflow velocity. Consequently, when the vehicle is moving, the air pressure on the side of the first deflector surface 11 of the air intake duct 201 is greater than the air pressure on the side of the second deflector surface 12, forming a pressure difference between the upper and lower surfaces of the deflector plate. Furthermore, the air pressure on the deflector plate is downward. When the vehicle is in high-speed mode, the deflector plate can work in conjunction with the tail wing separately set at the rear of the vehicle body 1000 to further reduce vehicle drift and help improve the handling and safety of the vehicle at high speeds.

[0041] Further, refer to Figure 5The first guide surface 11 can be a plane, and the second guide surface 12 can be an arc-shaped surface. The leading and trailing edges of the first guide surface 11 and the second guide surface 12 are smoothly connected in the air intake direction. In the air intake direction, the distance between the first guide surface 11 and the second guide surface 12 first increases and then decreases. As a result, when air flows through the second guide surface 12, the airflow area on the side of the second guide surface 12 of the air intake duct 201 decreases, which increases the air velocity. Consequently, when the vehicle is moving, the air pressure on the side of the first guide surface 11 of the air intake duct 201 is greater than the air pressure on the side of the second guide surface 12, forming a pressure difference between the upper and lower surfaces of the guide plate. Furthermore, the air pressure on the guide plate is downward. When the vehicle is traveling at high speed, the guide plate, together with the tail wing separately set at the rear of the vehicle body 1000, further reduces the vehicle's drift phenomenon and helps to improve the vehicle's handling and safety at high speeds.

[0042] Of course, the present invention is not limited to this. The first guide surface 11 can also be formed as an upwardly convex curved surface. In this case, the curvature of the first guide surface 11 is much smaller than the curvature of the second guide surface 12. In this way, a pressure difference can also be formed on the upper and lower sides of the guide plate, so that the air has a downward pressure effect on the guide plate.

[0043] Furthermore, refer to Figure 5 The position where the maximum distance between the first guide surface 11 and the second guide surface 12 is located at the rear of the guide component 1 along its length direction. This helps to increase the effective area of ​​the part of the guide component 1 that can cause the air to exert downward pressure on it, thereby increasing the downward pressure of the air on the guide component 1 and helping to improve the stability of the vehicle at high speeds.

[0044] According to some embodiments of the present invention, reference Figures 1-4 Multiple guide elements 1 can be provided, and these multiple guide elements 1 are arranged vertically within the air intake duct 201. The driving element 2 can include multiple elements corresponding one-to-one with the guide elements 1. The control of the multiple guide elements 1 is independent of each other; that is, whether each guide element 1 rotates and its rotation angle can be controlled independently, for example... Figure 1 As shown, when two air deflectors 1 are provided, one air deflector 1 can be in an open state and the other in a closed state, or both air deflectors 1 can be in an open state or both in a closed state simultaneously, or the rotation angles of the two air deflectors 1 can be the same or different. In this way, the airflow area of ​​the air intake duct 201 can be flexibly adjusted, thereby improving the airflow field in the rear engine compartment of the vehicle and improving the overall vehicle drag while meeting the air intake requirements. In addition, by changing the rotation angle of the two air deflectors, the airflow field near the two air deflectors can be changed, and the airflow field changing at a certain frequency helps to clean some impurities on the radiator of the vehicle's power system.

[0045] Further, refer to Figure 3The flow guide 1 can be formed as a flow guide 1. In two adjacent flow guides 1 in the vertical direction, a sealing recess 13 is formed at the top of the flow guide 1 located on the lower side. The sealing recess 13 can be formed by the lower flow guide 1 recessing along the thickness direction on one side surface in the thickness direction. A sealing mating part (not shown in the figure) is formed at the bottom of the flow guide 1 located on the upper side. The sealing mating part can be formed by the upper flow guide 1 recessing along the thickness direction on the other side surface in the thickness direction. When multiple flow guides 1 close the air intake 201, the sealing recess 13 and the sealing mating part abut and fit along the thickness direction of the flow guide 1.

[0046] For example Figure 3 As shown, there are two guide vanes. The upper end of the first guide surface 11 of the lower guide vane is recessed towards the second guide surface 12 to form a stepped sealing recess 13. The lower end of the second guide surface 12 of the upper guide vane is recessed towards the first guide surface 11 to form an inverted stepped sealing mating part. When the two guide vanes jointly close the air intake 201, the sealing recess 13 and the sealing mating part abut against each other in the front-rear direction. This improves the sealing performance of the air intake 201 in the closed state. On the other hand, since the guide member 1 moves by rotation and is only connected to the side wall of the air intake 201 by a pivot, the guide member 1 is prone to wobbling. The sealing recess 13 and the sealing mating part cooperate with each other, allowing the two adjacent guide members 1 in the vertical direction to interfere with each other when closing the air intake 201, thereby improving the stability of the guide member 1 when closing the air intake 201.

[0047] Furthermore, the air deflector is connected by an arc transition between any two adjacent surfaces, which reduces air resistance when the airflow passes over the air deflector and reduces wind power loss.

[0048] In some embodiments, reference Figures 1-4 The driving component 2 is a drive motor. The driving component 2 is located on one side of the guide component 1 along the width direction of the vehicle body 1000 and is not in the airflow path of the intake duct 201, for example... Figure 1 As shown, the air guide 1 is the air guide 1 on the right side of the vehicle body 1000. The drive motor can be located on the side of the air guide 1 closer to the vehicle interior (left side). The drive shaft of the drive motor is connected to the air guide 1 to drive the air guide 1 to rotate. The drive motor avoids the airflow path of the air intake duct 201, which can further reduce the wind resistance in the air intake duct 201 and improve the air intake efficiency.

[0049] According to some embodiments of the present invention, reference Figures 1-4 The cross-section of the air intake 201 is arc-shaped at all points in the circumference, which helps to further reduce the wind resistance of the air intake 201 and improve the intake efficiency.

[0050] The following describes a vehicle body 1000 according to a second aspect embodiment of the present invention.

[0051] The vehicle body 1000 according to an embodiment of the present invention is used for a vehicle, for example, a sports car or other type of sedan. The vehicle body 1000 may include a guide mechanism 100 according to the above embodiment of the present invention. Specifically, side panels 200 may be provided on both sides of the vehicle body 1000, an air intake duct 201 may be formed on the corresponding side panel 200, and the guide mechanism 100 may be disposed in the air intake duct 201.

[0052] According to the vehicle body 1000 of the present invention, the air intake duct 201 can be conveniently changed and the air intake volume of the air intake duct 201 can be adjusted as needed through the air guide mechanism 100 of the above embodiment, so that the vehicle can cope with the power and heat dissipation requirements under different working conditions, and can also meet the air intake flow field requirements of the vehicle's rear engine compartment under different low speed and high speed modes, and different high temperature and low temperature environments, which is conducive to improving the driving experience of the vehicle.

[0053] The vehicle according to a third aspect of the present invention is described below.

[0054] The vehicle according to the embodiments of the present invention is a rear-mounted powertrain vehicle, that is, the powertrain is located in the rear engine compartment of the vehicle. For example, the vehicle can be a sports car or other types of sedans, and the vehicle can include the body 1000 according to the above embodiments.

[0055] According to the vehicle of the present invention, by setting the body 1000 of the above embodiment, it can meet the power and heat dissipation requirements under different working conditions, and can also meet the air intake flow field requirements of the vehicle's rear engine compartment under different low-speed and high-speed modes, and different high-temperature and low-temperature environments, which is conducive to improving the driving experience of the vehicle.

[0056] The following examples illustrate the control methods of the flow guiding mechanism 100 when the vehicle is in different working states in this embodiment.

[0057] When the vehicle is traveling at high speed, the engine generates a lot of heat and the temperature is high. The rear engine compartment of the vehicle needs a lot of air intake and heat dissipation. The air guide 1 can be opened to allow air intake duct 201 to take in air. At this time, the air guide structure of the air guide 1 can also provide downforce to the vehicle and improve the power of the sports car.

[0058] When the vehicle is in BEV pure electric mode, since the rear engine compartment components do not require air intake, the air intake duct 201 is closed by closing the air guide 1, which helps to reduce the overall vehicle drag.

[0059] When the vehicle is running in winter or idling, the air intake 201 can be closed by closing the air deflector 1, which helps to quickly heat up the rear engine compartment.

[0060] When the vehicle is traveling at normal high speeds, considering that the air intake requirements of the rear engine compartment are not stringent, one of the air deflectors 1 can be opened and the other air deflector 1 can be closed. This can reduce the overall vehicle drag while still meeting air intake requirements. Furthermore, the airflow can be pushed downwards by a larger rotation angle, improving the airflow field in the engine compartment.
