[0033] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0034] Reference below Figures 1-8 A fairing structure 100 according to an embodiment of the present invention is described. The present invention also provides a vehicle including the fairing structure 100 .

[0035] exist Figures 1-6 The width direction of the vehicle is Figure 1-5 The left and right directions in the Figures 1-6 The front-to-back direction.

[0036] Reference Figure 1-Figure 5 As shown, the air deflector structure 100 of the present invention is fixed to the bumper 200. Specifically, there may be two air deflector structures 100, one on each side of the bumper 200 in the vehicle width direction. The air deflector structure 100 includes an outer air deflector 10 and an inner air deflector 20, which are fixedly connected to the bumper 200. The inner air deflector 20 is fixedly connected to the bumper 200, and the inner air deflector 20 is connected to the outer air deflector 10 to secure the inner air deflector 20 and the outer air deflector 10 to the bumper 200.

[0037] The bumper 200 may be located at the front side of the vehicle.

[0038] according to Figure 4 and Figure 5As shown, the outer air guide cover 10 is provided with an air guide hole 11, and the inner air guide cover 20 is provided with an air guide channel 31, and the air guide channel 31 is connected to the air guide hole 11. In other words, the bumper 200 is provided with an opening, and the periphery of the opening of the inner air guide cover 20 is connected. The portion of the inner air guide cover 20 connected to the opening is sandwiched between the outer air guide cover 10 and the bumper 200. The outer air guide cover 10 is provided with an air guide hole 11, and the air guide hole 11 corresponds to the opening, so that airflow enters the air guide channel 31 of the inner air guide cover 20 from the air guide hole 11 and the opening, so that airflow flows to the rear of the vehicle, reducing wind resistance experienced by the vehicle.

[0039] Reference Figure 5 and Figure 6 As shown, the guide inner cover 20 includes: a first inner cover 21 and a second inner cover 22, the first inner cover 21 and the second inner cover 22 are connected to each other, a first step 23 is provided on the first inner cover 21, and a second step 24 is provided on the second inner cover 22, the first step 23 and the second step 24 overlap each other, and at least one surface of the first step 23 and the second step 24 are in close contact. Specifically, the first inner cover 21 and the second inner cover 22 are connected, and a guide channel 31 is formed between the first inner cover 21 and the second inner cover 22. A first step 23 is provided on the side of the first inner cover 21 facing the second inner cover 22, and a second step 24 is provided on the side of the second inner cover 22 facing the first inner cover 21. The first step 23 and the second step 24 overlap with each other so that the first inner cover 21 and the second inner cover 22 are tightly matched. At least one surface of the first step 23 and the second step 24 are in close contact, that is, the gap between at least one surface of the first step 23 and the second step 24 is 0, and at least one surface of the overlap of the first inner cover 21 and the second inner cover 22 is in close contact, ensuring the tightness of the fit of the first inner cover 21 and the second inner cover 22.

[0040] like Figure 5 and Figure 6 As shown, both the first step 23 and the second step 24 include: a first mating surface 25, a second mating surface 26, and a third mating surface 27. The second mating surface 26 is connected between the first mating surface 25 and the third mating surface 27. The two first mating surfaces 25 are in close contact with each other, and / or the two second mating surfaces 26 are in close contact with each other, and / or the two third mating surfaces 27 are in close contact with each other. Specifically, the first step 23 includes at least three surfaces, namely, the first mating surface 25, the second mating surface 26, and the third mating surface 27. The second step 24 includes at least three surfaces, namely, the first mating surface 25, the second mating surface 26, and the third mating surface 27. The second mating surface 26 is connected between the first mating surface 25 and the third mating surface 27.

[0041] If the two first mating surfaces 25 are in close contact, that is, the gap between the two first mating surfaces 25 is 0, it ensures that the first inner cover 21 and the second inner cover 22 are locally compressed without gaps, reduces the airflow entering the cabin, improves the wind guiding effect of the deflector structure 100, and reduces the wind resistance of the vehicle.

[0042] If the two second mating surfaces 26 are in close contact, that is, the gap between the two second mating surfaces 26 is 0, it ensures that the first inner cover 21 and the second inner cover 22 are locally compressed without gaps, reduces the airflow entering the cabin, improves the wind guiding effect of the deflector structure 100, and reduces the wind resistance of the vehicle.

[0043] If the two third mating surfaces 27 are in close contact, that is, the gap between the two third mating surfaces 27 is 0, it ensures that the first inner cover 21 and the second inner cover 22 are partially compressed without gaps, reduces the airflow entering the cabin, improves the wind guiding effect of the deflector cover structure 100, and reduces the wind resistance of the vehicle.

[0044] Therefore, at least one surface of the first step 23 and the second step 24 are in close contact, ensuring that the step difference of the air deflector inner cover 20 is in accordance with the design, avoiding the problem of airflow entering the cabin due to the step difference problem in the later stage, and effectively improving the ventilation effect of the air deflector structure 100 and reducing the wind resistance of the vehicle.

[0045] like Figure 5 As shown, the first inner cover 21 is provided with a first clamping portion 211, and the second inner cover 22 is provided with a second clamping portion 221. The first clamping portion 211 and the second clamping portion 221 are engaged with each other. At the engagement point between the first clamping portion 211 and the second clamping portion 221, the two second mating surfaces 26 are in close contact, and a gap is provided between the two first mating surfaces 25 and between the two third mating surfaces 27. Specifically, the first clamping portion 211 and the second clamping portion 221 are engaged with each other so that the second mating surface 26 of the first step 23 and the second mating surface 26 of the second step 24 are in close contact. That is, the gap between the two second mating surfaces 26 is zero, effectively improving the air guide effect of the air deflector structure 100.

[0046] A gap is set between the two first mating surfaces 25, and a gap is set between the two third mating surfaces 27 to ensure that the middle part of the overlap of the first step 23 and the second step 24 is pressed tightly without any gaps, and to ensure that there is a local mating gap at the overlap of the first inner cover 21 and the second inner cover 22 to prevent the problem of too small a gap from occurring.

[0047] In addition, there can be multiple first clamping parts 211 and multiple second clamping parts 221, and the multiple first clamping parts 211 are respectively clamped and matched with the multiple second clamping parts 221 to ensure the tightness of the fit at each position of the overlap between the first inner cover 21 and the second inner cover 22.

[0048] like Figure 6 As shown, the first inner cover 21 is provided with a crimping portion 212, which is pressed against the second inner cover 22. At the crimping portion 212, the two second mating surfaces 26 are in close contact, and a gap is provided between the two first mating surfaces 25 and between the two third mating surfaces 27. Specifically, the crimping portion 212 is provided on the first inner cover 21 and can abut against the second inner cover 22, serving as an assembly guide and preventing the edge of the second inner cover 22 from warping and leaking.

[0049] At the crimping portion 212, the second mating surface 26 of the first step 23 and the second mating surface 26 of the second step 24 are in close contact, that is, the gap between them is zero, effectively improving the air guide effect of the air deflector structure 100. A gap is provided between the two first mating surfaces 25 and the two third mating surfaces 27 to ensure a mating gap between the first inner cover 21 and the second inner cover 22, preventing the occurrence of a gap that is too small.

[0050] like Figure 5 As shown, at the junction of the first engaging portion 211 and the second engaging portion 221, the gap between the two first mating surfaces 25 is h1, and the gap between the two third mating surfaces 27 is h2. h1 and h2 satisfy the relationship: h1 < h2. Specifically, at the junction of the first engaging portion 211 and the second engaging portion 221, the gap between the first mating surface 25 of the first step 23 and the first mating surface 25 of the second step 24 is smaller than the gap between the third mating surface 27 of the first step 23 and the third mating surface 27 of the second step 24.

[0051] Furthermore, 0.08 mm < h1 < 0.12 mm. That is, the gap between the first mating surface 25 of the first step 23 and the first mating surface 25 of the second step 24 is between 0.08 mm and 0.12 mm, ensuring that there is some gap between the first inner cover 21 and the second inner cover 22 to prevent deformation of the first inner cover 21 and the second inner cover 22 due to the small gap when the vehicle shakes.

[0052] At the connection point between the first clamping portion 211 and the second clamping portion 221, if the gap between the first mating surface 25 of the first step 23 and the first mating surface 25 of the second step 24 is less than or equal to 0.18 mm, the gap between the two first mating surfaces 25 is too small, and the first inner cover 21 and the second inner cover 22 are easily deformed when the vehicle shakes; if the gap between the first mating surface 25 of the first step 23 and the first mating surface 25 of the second step 24 is less than or equal to 0.22 mm, the gap between the two first mating surfaces 25 is too large, part of the airflow enters the cabin, and the wind guiding effect is poor.

[0053] Furthermore, at the junction between the first and second engaging portions 211, 221, 0.18 mm < h2 < 0.22 mm. Specifically, the gap between the second mating surface 26 of the first step 23 and the second mating surface 26 of the second step 24 is between 0.08 mm and 0.12 mm, ensuring a gap between the first and second inner covers 21, 22 to prevent deformation due to insufficient clearance during vehicle sway.

[0054] At the connection point between the first clamping portion 211 and the second clamping portion 221, if the gap between the second mating surface 26 of the first step 23 and the second mating surface 26 of the second step 24 is less than or equal to 0.18 mm, the gap between the two second mating surfaces 26 is too small, and the first inner cover 21 and the second inner cover 22 are easily deformed when the vehicle shakes; if the gap between the second mating surface 26 of the first step 23 and the second mating surface 26 of the second step 24 is less than or equal to 0.22 mm, the gap between the two second mating surfaces 26 is too large, part of the airflow enters the cabin, and the wind guiding effect is poor.

[0055] like Figure 6 As shown, at the crimping portion 212, the gap between the two first mating surfaces 25 is h3, and the gap between the two third mating surfaces 27 is h4. h3 and h4 satisfy the relationship: h3<h4. Specifically, at the crimping portion 212, the gap between the first mating surface 25 of the first step 23 and the first mating surface 25 of the second step 24 is smaller than the gap between the third mating surface 27 of the first step 23 and the third mating surface 27 of the second step 24, which facilitates assembly.

[0056] At the crimping portion 212, 0.08 mm < h3 < 0.12 mm. That is, at the crimping portion 212, the gap between the first mating surface 25 of the first step 23 and the first mating surface 25 of the second step 24 is between 0.08 mm and 0.12 mm. This ensures a gap between the first inner cover 21 and the second inner cover 22 to prevent deformation of the first and second inner covers 21 and 22 due to the small gap when the vehicle shakes.

[0057] At the crimping portion 212, if the gap between the first mating surface 25 of the first step 23 and the first mating surface 25 of the second step 24 is less than or equal to 0.18 mm, the gap between the two first mating surfaces 25 is too small, and the first inner cover 21 and the second inner cover 22 are easily deformed when the vehicle shakes; if the gap between the first mating surface 25 of the first step 23 and the first mating surface 25 of the second step 24 is less than or equal to 0.22 mm, the gap between the two first mating surfaces 25 is too large, and too much air flows into the cabin through the gap, resulting in poor wind guiding effect and increased wind resistance.

[0058] At the crimping portion 212, 0.28mm < h4 < 0.32mm. Specifically, at the crimping portion 212, the gap between the second mating surface 26 of the first step 23 and the second mating surface 26 of the second step 24 is between 0.08mm and 0.12mm. This ensures a slight gap between the first inner cover 21 and the second inner cover 22 to prevent deformation due to insufficient gap when the vehicle is shaken.

[0059] At the crimping portion 212, if the gap between the second mating surface 26 of the first step 23 and the second mating surface 26 of the second step 24 is less than or equal to 0.18 mm, the gap between the two second mating surfaces 26 is too small, and the first inner cover 21 and the second inner cover 22 are easily deformed when the vehicle shakes; if the gap between the second mating surface 26 of the first step 23 and the second mating surface 26 of the second step 24 is less than or equal to 0.22 mm, the gap between the two second mating surfaces 26 is too large, and too much air flows into the cabin through the gap, resulting in poor wind guiding effect and increased wind resistance.

[0060] In other embodiments, the gap between the inner air guide cover 20 and the bumper 200 is h5, where h5 satisfies the relationship: 0.18 mm < h5 < 0.22 mm. Furthermore, the inner air guide cover 20 and the outer air guide cover 10 are in close contact. Specifically, the gap between the inner air guide cover 20 and the bumper 200 is between 0.18 mm and 0.22 mm, ensuring a clearance between the inner air guide cover 20 and the bumper 200 and preventing deformation of the inner air guide cover 20 due to an insufficient clearance between the inner air guide cover 20 and the bumper 200.

[0061] like Figure 2 and Figure 3 As shown, the first inner cover 21 and the second inner cover 22 are each provided with a first positioning portion 32 and a first fixing portion 33, the first positioning portion 32 and the first fixing portion 33 being spaced apart from each other. The bumper 200 is provided with a second positioning portion 210 and a second fixing portion being spaced apart from each other. The first positioning portion 32 and the second positioning portion 210 are positioned and matched, and the first fixing portion 33 and the second fixing portion are fixedly connected. Specifically, the first inner cover 21 and the second inner cover 22 are each provided with a first positioning portion 32, which is positioned and matched with the second positioning portion 210 on the bumper 200. Therefore, there are at least two second positioning portions 210. Through the positioning and matching of the first positioning portion 32 and the second positioning portion 210, the first inner cover 21 and the second inner cover 22 are positioned and matched with the bumper 200. Multiple first positioning portions 32 and second positioning portions 210 can be provided to ensure the precision of the matching between the first inner cover 21 and the second inner cover 22 and the bumper 200.

[0062] The first inner cover 21 and the second inner cover 22 are both provided with a first fixing portion 33, and the bumper 200 is provided with a second fixing portion. The first fixing portion 33 is fixedly connected to the second fixing portion on the bumper 200, so there are at least two second fixing portions. The first fixing portion 33 and the second fixing portion are fixedly connected to the bumper 200, thereby fixing the first inner cover 21 and the second inner cover 22 to the bumper 200.

[0063] Furthermore, the outer side of the first inner cover 21 is provided with a plurality of reinforcing columns 28 and a plurality of reinforcing ribs 29. The plurality of reinforcing columns 28 are spaced apart from each other, and the plurality of reinforcing ribs 29 are connected between two adjacent reinforcing columns 28. Specifically, each reinforcing column 28 protrudes from the outer surface of the first inner cover 21. The plurality of reinforcing columns 28 are spaced apart, and the plurality of reinforcing ribs 29 are spaced apart. Each reinforcing column 28 is connected to four reinforcing ribs 29 to enhance the structural strength and rigidity of the first inner cover 21, prevent deformation due to injection molding or excessive wind speed that could cause airflow to enter the cabin, improve the wind deflection effect of the shroud structure 100, and reduce wind resistance experienced by the vehicle.

[0064] like Figure 2 As shown, the outer side of the second inner cover 22 is provided with multiple reinforcement columns 28 and multiple reinforcement ribs 29. The multiple reinforcement columns 28 are spaced apart from each other, and the multiple reinforcement ribs 29 are connected between two adjacent reinforcement columns 28. Specifically, each reinforcement column 28 protrudes from the outer surface of the first inner cover 21. The multiple reinforcement columns 28 are spaced apart, and the multiple reinforcement ribs 29 are spaced apart. Each reinforcement column 28 is connected to four reinforcement ribs 29 to enhance the structural strength and rigidity of the second inner cover 22, prevent deformation caused by injection molding or excessive wind speed that could cause airflow to enter the cabin, improve the wind deflection effect of the shroud structure 100, and reduce wind resistance on the vehicle.

[0065] A vehicle according to an embodiment of the second aspect of the present invention includes a fairing structure 100. At least one surface of a first step 23 on a first inner cover 21 and a second step 24 on a second inner cover 22 are in close contact, ensuring that the step difference during assembly of the fairing structure 100 meets the design, thereby preventing airflow from entering the cabin later due to the step difference. This effectively improves the ventilation of the fairing structure 100 and reduces wind resistance experienced by the vehicle.
