[0031] To address the related technical problems, this application provides a vehicle that includes the following vehicle body components.

[0032] To address the related technical problems, this application also provides a vehicle body component, for details please refer to [link / reference needed]. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of one embodiment of the vehicle body component provided in this application; Figure 2 yes Figure 1A first view of one embodiment of the air guide plate shown.

[0033] The vehicle body assembly 10 includes a front underbody guard 200, a wheel arch 300, and an air deflector 100. The wheel arch 300 is connected to the front underbody guard 200. The air deflector 100 is connected to the front underbody guard 200 and includes an air deflector surface 110. The air deflector surface 110 is away from the front underbody guard 200. The air deflector surface 110 has an air inlet side 120 and an air outlet side 130. The air inlet side 120 is further away from the wheel arch 300 than the air outlet side 130. The air outlet side 130 is spaced apart from the wheel arch 300. The air deflector surface 110 is used to guide airflow from the air inlet side 120 to the air outlet side 130 along the air deflector direction X. The air deflector 100 has at least one air deflector 140 at the edge of the air outlet side 130.

[0034] The front underbody guard 200 is located at the bottom of the vehicle body and is used to protect against impacts from the road surface. The wheel covers 300 are provided corresponding to the vehicle wheels. The two ends of the wheel covers 300 are fixedly connected to the front underbody guard 200. The wheel covers 300 can be used to cover and protect the wheels.

[0035] The air guide plate 100 is connected to the front bottom guard plate 200. The air guide plate 100 has an air guide surface 110, which is located on the side of the air guide plate 100 away from the front bottom guard plate 200. The air guide surface 110 can be relatively smooth, which helps to reduce wind resistance. The air guide surface 110 has an air inlet side 120 and an air outlet side 130. The direction from the air inlet side 120 to the air outlet side 130 can be the air guide direction X. The air inlet side 120 is located at the end of the air guide surface 110 away from the vehicle wheel arch 300 in the air guide direction X. The air outlet side 130 is located at the end of the air guide surface 110 close to the vehicle wheel arch 300 in the air guide direction X. The air outlet side 130 is also separated from the vehicle wheel arch 300 by a certain distance, so that there is a certain space between the air outlet side 130 and the vehicle wheel arch 300. The airflow can be guided from the air inlet side 120 to the air outlet side 130 by the air guide surface 110. Then the airflow is guided to the space between the air outlet side 130 and the vehicle wheel arch 300, and thus is driven to the rear of the vehicle by the rotating vehicle wheels, thereby achieving the purpose of reducing wind resistance. Furthermore, at least one air vent 140 is provided on the air outlet side 130 of the air deflector 100, which disperses the airflow as it passes through the air outlet side 130. The dispersed airflow is guided to the space between the air outlet side 130 and the vehicle wheel arch 300, thereby allowing the airflow to be smoothly guided from the air inlet side 120 to the air outlet side 130 through the air guide surface 110 and the air vent 140. Exemplarily, the air vent 140 may only penetrate one side of the air deflector 100 away from the front bottom guard plate 200. Further, the air vent 140 may also penetrate both opposite sides of the air deflector 100 to improve the dispersion effect of the airflow on the air outlet side 130.

[0036] Through the above implementation method, the air guide plate 100 can guide the airflow from the air inlet side 120 to the air outlet side 130. The air outlet side 130 of the air guide plate 100 is provided with an air guide port 140. The airflow passes through the air guide port 140 to disperse the airflow, which can reduce the air pressure on the air outlet side 130, increase the air volume, reduce the wind resistance, and also reduce the risk of the air guide plate 100 being damaged due to excessive pressure on the air outlet side 130.

[0037] See Figure 3 , Figure 3 yes Figure 1 A second view of one embodiment of the air guide plate shown.

[0038] In some embodiments, the air guide plate 100 includes a rigid member 210 and a flexible member 220, which are connected together. The rigid member 210 and the flexible member 220 together form an air guide surface 110 on the side away from the front bottom guard plate 200, and an air guide port 140 is opened on the flexible member 220.

[0039] The air guide plate 100 can be divided into two parts: a rigid component 210 and a flexible component 220. The rigid component 210 can be understood as a component with higher material hardness and a certain degree of deformation capability. The rigid component 210 provides a certain structural strength for the air guide plate 100. The flexible component 220 can be understood as a component with lower material hardness. The flexible component 220 is softer than the rigid component 210 and can deform to a greater extent. Both the rigid component 210 and the flexible component 220 can be injection molded parts, both can be plastic, and can be manufactured by two-color injection molding, which is simple to manufacture. When a vehicle is traveling on uneven road surfaces, the air deflector 100 may be impacted, especially when the rigid component 210 is impacted. Because the flexible component 220 is connected to the rigid component 210, the flexible component 220 allows the rigid component 210 a certain degree of deformation space. This deformation space can be understood as the range within which the air deflector 100 can deform towards the front bottom guard plate 200 without breaking. After the air deflector 100 deforms, the vehicle can smoothly pass through the road section, thereby improving the vehicle's passability. Furthermore, after passing through the road section, the flexible component 220 and the rigid component 210 can return to their initial state, which is the state of the air deflector 100 before the impact. The connection between the rigid component 210 and the flexible component 220 ensures that the rigid component 210 deforms upon impact without being directly damaged, thus reducing the risk of damage to the air deflector 100 due to impact.

[0040] As an example, the rigid component 210 and the flexible component 220 can be connected in the air guiding direction X. The rigid component 210 can be located at the end closer to the air outlet side 130, and the flexible component 220 can be located at the end closer to the air inlet side 120. The air guide 140 can be opened on the rigid component 210, thereby achieving the purpose of reducing wind resistance of the air guide plate 100. The rigid component 210 has a certain deformation space, which can also reduce the risk of damage to the air guide plate 100. As another example, the rigid component 210 and the flexible component 220 can be connected in the air guiding direction X. The rigid component 210 can be located at the end closer to the air inlet side 120, and the flexible component 220 can be located at the end closer to the air outlet side 130. Based on this, the air guide 140 can be located on the flexible component 220. Since the flexible component 220 is more easily deformed, when the air pressure on the outlet side 130 is high, the flexible component 220 can adapt to the air pressure on the outlet side 130 in a timely manner through deformation, thereby reducing the risk of damage to the outlet side 130 of the air guide plate 100. Furthermore, after the flexible component 220 deforms, it can also improve the air dispersion effect of the air guide 140, thereby further reducing wind resistance. As another example, the flexible component 220 can be located between the inlet side 120 and the outlet side 130 in the air guiding direction X. The flexible component 220 is connected to the rigid component 210 on both sides in the air guiding direction X. The rigid component 210 located on both sides of the flexible component 220 can deform when subjected to pressure.

[0041] In some embodiments, the air deflector 100 can be installed in a multi-purpose vehicle (MPV). Since the front underbody protection plate 200 of an MPV has a low ground clearance, installing the air deflector 100 may result in insufficient ground clearance and failure to meet approach angle and step protection limits. Therefore, by installing the rigid component 210 and the flexible component 220, the passability of the MPV can be improved. Of course, in other embodiments, the air deflector 100 can also be applied to passenger cars and sport utility vehicles (SUVs).

[0042] In some embodiments, the rigid member 210 includes a first rigid portion 211, a second rigid portion 212, and a third rigid portion 213. The second rigid portion 212 is connected between the first rigid portion 211 and the third rigid portion 213. The first rigid portion 211 is close to the air inlet side 120, and the third rigid portion 213 is close to the air outlet side 130. In the width direction Y intersecting the air guiding direction X, the size of the second rigid portion 212 is smaller than the size of the first rigid portion 211 and the third rigid portion 213.

[0043] The rigid component 210 includes a first rigid part 211, a second rigid part 212, and a third rigid part 213 connected in sequence. The first rigid part 211 is close to the air inlet side 120, and the third rigid part 213 is close to the air outlet side 130. The second rigid part 212 is smaller in the width direction Y than the first rigid part 211 and the third rigid part 213, thereby weakening the middle part of the rigid component 210. That is, by setting the smaller second rigid part 212, the local structural strength of the rigid component 210 can be reduced, so that the rigid component 210 can be more easily deformed and has a larger deformation space while having a certain structural strength, so as to further reduce the risk of the air guide plate 100 being damaged by impact. For example, the second hard portion 212 may be located at any position between the two ends of the first hard portion 211 and the third hard portion 213 in the width direction Y. For example, the second hard portion 212 may be located in the width direction Y near the ends of the first hard portion 211 and the third hard portion 213; or the second hard portion 212 may be located in the width direction Y away from the ends of the first hard portion 211 and the third hard portion 213.

[0044] In some embodiments, the soft component 220 includes a first soft portion 221 and a second soft portion 222, which extend along the width direction Y. The first soft portion 221 and the second soft portion 222 are located on both sides of the second hard portion 212 in the width direction Y. The first soft portion 221 and the second soft portion 222 are respectively connected to the first hard portion 211 and the second hard portion 212 in the airflow direction X.

[0045] The first rigid portion 211 and the third rigid portion 213 are connected by the smaller third rigid portion 213, thereby forming a gap extending in the width direction Y between the first rigid portion 211 and the third rigid portion 213 in the airflow direction X. The flexible component 220 includes a first flexible portion 221 and a second flexible portion 222, which fill the gap. Specifically, the first flexible portion 221 and the second flexible portion 222 extend in the width direction Y, are located on both sides of the second rigid portion 212 in the width direction Y, and are respectively connected to the first rigid portion 211 and the second rigid portion 212 on both sides in the airflow direction X. Thus, the first rigid portion 211 and the third rigid portion 213 are connected not only by the second rigid portion 212, but also by the first flexible portion 221 and the second flexible portion 222. Since the second hard part 212 has low structural strength, it is easy to break. By connecting the first hard part 211 and the third hard part 213 through the first soft part 221 and the second soft part 222, the structural strength at the corresponding position can be improved, and the hard part 210 can also have better self-adaptive function.

[0046] In some embodiments, the soft component 220 further includes a third soft portion 223, which is connected to the first soft portion 221 and the second soft portion 222 respectively. The third soft portion 223 extends along the width direction Y and is close to the air outlet side 130. The air guide 140 is opened in the third soft portion 223.

[0047] The third soft part 223 extends in the width direction Y and is close to the air outlet side 130. The two ends of the third soft part 223 in the width direction Y are respectively connected to the first soft part 221 and the second soft part 222. The air guide 140 is disposed on the third soft part 223 and can extend in the width direction Y, so that the first soft part 221, the second soft part 222 and the third soft part 223 surround the third hard part 213 and are all connected to the third hard part 213. This can increase the deformation space of the third hard part 213. When the air guide plate 100 is subjected to a greater impact, the third hard part 213 can have a greater deformation capacity, thereby further reducing the risk of damage to the air guide plate 100.

[0048] See Figure 4 , Figure 4 yes Figure 1 The third view of one embodiment of the air guide plate shown.

[0049] In some embodiments, the third soft part 223 includes a first air guide part 224 and a second air guide part 225. The second air guide part 225 is connected to the end of the first air guide part 224 away from the third hard part 213. The second air guide part 225 is arranged in the thickness direction Z in a direction away from the air guide surface 110. The first air guide part 224 and the second air guide part 225 are respectively provided with a first air outlet 2241 and a second air outlet 2251. The first air outlet 2241 and the second air outlet 2251 are connected to form an air guide, wherein the air guide direction X, the width direction Y and the thickness direction Z intersect each other.

[0050] The third soft part 223 includes a first air guide part 224 and a second air guide part 225. The side of the first air guide part 224 away from the front bottom guard plate 200 forms part of the air guide surface 110. The two ends of the first air guide part 224 in the air guide direction X are respectively connected to the third hard part 213 and the second air guide part 225. The second air guide part 225 is arranged in the thickness direction Z of the air guide plate 100, so that the air outlet side 130 of the air guide surface 110 is further away from the front bottom guard plate 200 in the thickness direction Z than the air inlet side 120. The second air guide part 225 is located between the air guide surface 110 and the front bottom guard plate 200 in the width direction Y. Thus, the second air guide part 225 can provide a larger deformation space for the hard part 210, which can further reduce the risk of damage to the air guide plate 100. In addition, the first air guide section 224 and the second air guide section 225 are respectively provided with a first air vent 2241 and a second air vent 2251. The first air vent 2241 and the second air vent 2251 are interconnected to form an air guide 140. Since the first air guide section 224 and the second air guide section 225 are arranged in different directions, the first air vent 2241 and the second air vent 2251 have different orientations. The first air vent 2241 is oriented away from the front bottom guard plate 200 in the thickness direction Z, and the second air vent 2251 is oriented closer to the vehicle wheel arch 300 in the air guide direction X. Therefore, when the airflow is guided from the air inlet side 120 to the first air outlet 2241, since the second air outlet 2251 is connected to the first air outlet 2241, part of the airflow is dispersed by the first air outlet 2241, and part of the airflow is further guided to the second air outlet 2251. The second air outlet 2251 then disperses this part of the airflow again, thus the first air outlet 2241 and the second air outlet 2251 disperse the airflow twice, improving the dispersion effect of the airflow and further reducing wind resistance. Of course, in some other embodiments, the second air guide 225 may also be made of the same material as the rigid component 210, and the second air outlet 2251 connected to the first air outlet 2241 may only be provided in the second air guide 225.

[0051] In this embodiment, the third soft part 223 can be arc-shaped, and the third soft part 223 can match the arc shape of the vehicle wheel cover 300, so that the distance between each part of the air guide 140 and the vehicle wheel is approximately the same. When the vehicle wheel rotates, the vehicle wheel can drive the airflow guided from the air guide 140. Since the distance between each part of the air guide 140 and the vehicle wheel is the same, the guided airflow is more stable, which helps to reduce wind resistance.

[0052] In some embodiments, the soft component 220 may include a fourth soft portion and a fifth soft portion, which extend in the guiding direction. The fourth soft portion is connected to the second soft portion 222 and the third soft portion 223, respectively, and the fifth soft portion is connected to the first soft portion 221 and the third soft portion 223, respectively. This allows the first soft portion 221, the second soft portion 222, the third soft portion 223, the fourth soft portion, and the fifth soft portion to form a large-sized annular structure, which is connected to the periphery of the third hard portion 213. This results in the third hard portion 213 having a larger area, increasing the area of ​​the deformable portion of the hard component 210, and further reducing the risk of damage to the hard component 210. Furthermore, like the second air guide portion 225, the fourth and fifth soft portions are also positioned in the width direction Y towards the front bottom guard plate 200, thereby further increasing the deformation space of the hard component 210 and further reducing the risk of damage to the hard component 210.

[0053] In some embodiments, there are multiple first air vents 2241 and multiple second air vents 2251, the number of first air vents 2241 and the number of second air vents 2251 are equal, and the multiple first air vents 2241 and multiple second air vents 2251 are spaced apart in the width direction Y.

[0054] The number of air vents 140 can be multiple, and each air vent 140 can consist of a first air vent 2241 and a second air vent 2251. The multiple air vents 140 are spaced apart in the width direction Y, thereby improving the structural strength of the third soft part 223 and reducing the risk of collapse of the air vents 140 due to low structural strength, which would lead to a decrease in the wind resistance reduction effect. Furthermore, the dimensions of the first air vent 2241 and the second air vent 2251 in the width direction Y can be equal or unequal. For example, the dimension of the second air vent 2251 in the width direction Y can be larger than the dimension of the first air vent 2241, thereby improving the airflow dispersion effect of the second air vent 2251 and further reducing wind resistance.

[0055] Each air vent 140 can have a width in the Y direction ranging from 20mm to 30mm. Within this range, the width of the air vent 140 can effectively disperse airflow. The width of the air vent 140 in the Y direction can be 20mm, 22mm, 25mm, 28mm, or 30mm, or any range formed by any two of these values, such as 20mm–22mm, 22mm–25mm, or 25mm–28mm.

[0056] In some embodiments, the vehicle body assembly 10 includes a front bumper skin 400, and a connecting seam 150 is formed between one end of the air intake side 120 of the air deflector 100 and the front bottom guard plate 200, with the front bumper skin 400 covering the connecting seam 150.

[0057] The air intake side 120 of the air deflector 100 has a connecting seam 150 with the front bottom guard plate 200. The vehicle body assembly 10 also includes a front bumper skin 400, which is located on the air intake side 120 of the air deflector 100 and covers the connecting seam 150. Specifically, the end of the front bumper near the front bottom guard plate 200 in the thickness direction Z may protrude from the front bottom guard plate 200. The air intake side 120 of the air deflector 100 is located at the protruding position of the front bumper skin 400 relative to the front bottom guard plate 200, so that the protruding part of the front bumper skin 400 covers the connecting seam 150. Therefore, most of the airflow on the air inlet side 120 will not enter the connection seam 150 between the front bumper skin 400 and the air deflector 100, so as to reduce the obstruction of the airflow by the air deflector 100. Most of the airflow will be guided to the air outlet side 130 by the air inlet side 120 of the air guide surface 110, which helps to reduce wind resistance.

[0058] In some embodiments, air ducts can be provided on the front bumper skin 400 and wheel arches 300 to reduce wind resistance. However, the placement of these air ducts depends on the vehicle's exterior design, and some vehicle designs are not conducive to installing air ducts. Therefore, the wind deflector 100 provided in this application is located at the bottom of the vehicle. Specifically, the wind deflector 100 is connected to the front bottom guard plate 200. This design makes the wind deflector 100 independent of the vehicle's exterior design. Therefore, installing the wind deflector 100 on vehicles without air ducts can effectively reduce wind resistance. Moreover, compared to installing air ducts, installing the wind deflector 100 has wider applicability. Furthermore, the wind deflector provided in this application is more effective at reducing wind resistance than air ducts. Of course, in other embodiments, the vehicle can be equipped with both air ducts and wind deflectors 100 to jointly reduce wind resistance.

[0059] In some embodiments, the air guide surface 110 is an arc surface. In the direction from the air inlet side 120 to the air outlet side 130, the width direction Y intersecting with the air guide direction X and the air guide direction X constitute a reference plane, and the angle between the air guide surface 110 and the reference plane gradually decreases.

[0060] The air guide surface 110 is curved, and the center of the arc of the air guide surface 110 is located on the side of the air guide plate 100 near the front bottom guard plate 200 in the thickness direction Z. In other words, taking the plane formed by the air guiding direction X and the width direction Y as the reference plane, the angle between the air guide surface 110 and the reference plane gradually decreases in the direction from the air inlet side 120 to the air outlet side 130. As a result, the airflow can be effectively guided from the air inlet side 120 to the air outlet side 130 by the curved air guide surface 110, thereby reducing wind resistance. Furthermore, the angle between the end of the air guide plate 100 near the air outlet side 130 and the reference plane can approach 0, thereby further reducing wind resistance. The angle between the end of the air guide surface 110 on the air inlet side 120 and the reference plane can be in the range of 5°-10°, within which the airflow guiding effect is better. The angle between the air inlet side 120 of the air guide surface 110 and the reference plane can be 5°, 5.5°, 6.5°, 7°, 8°, 8.5°, 9°, 10°, or a range of any two of the above values, such as 5°~6.5°, 6.5°~8°, 8°~9°, 9°~10°.

[0061] In some embodiments, there may be two air guide plates 100, which are spaced apart in the width direction Y and located at both ends of the front bottom guard plate 200 in the width direction Y. The end of the air guide plate 100 near the air inlet side 120 may also be arc-shaped. Specifically, the angle between the air guide plate 100 and the width direction Y gradually increases from the end near the other air guide plate 100 to the end away from the other air guide plate 100. This design can reduce wind resistance. Of course, based on the above embodiments, in some other embodiments, there may be more air guide plates 100, with multiple air guide plates 100 spaced apart in the width direction Y and located between the two air guide plates 100 at both ends; or there may be only one air guide plate 100, which extends in the width direction Y. That is to say, multiple air guide plates 100 in the previous embodiment can be connected to each other to form a single air guide plate 100 extending in the width direction Y, thereby further reducing wind resistance.

[0062] In some embodiments, the air deflector 100 further includes a connecting portion disposed on the outer periphery of the air deflector 100, so that the air deflector 100 is connected to the front bottom guard plate 200 through the connecting portion. The connecting portion can be connected to other components by means of snap-fit ​​or screw-fit. Of course, the periphery of the connecting portion can also be fixedly connected to the front bottom guard plate 200, the wheel arch 300 and the front bumper skin 400 at the same time.

[0063] In summary, the air guide plate 100 can guide the airflow from the air inlet side 120 to the air outlet side 130. The air outlet side 130 of the air guide plate 100 is provided with an air guide port 140. The airflow passes through the air guide port 140 to disperse the airflow, which can reduce the air pressure on the air outlet side 130, increase the air volume, reduce the wind resistance, and also reduce the risk of the air guide plate 100 being damaged due to excessive pressure on the air outlet side 130.
