Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a vehicle body side panel and a vehicle. Background Technology

[0002] For new energy vehicles, the overall driving range has always been a key focus for users. The magnitude of air resistance is a significant factor affecting driving range. Given a fixed external dimension, reducing the drag coefficient is a major research focus for automakers. In related technologies, an unreasonable structural design in the side and rear areas of the vehicle leads to an increased drag coefficient. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a vehicle side panel that can reduce the probability of airflow from the side and rear of the vehicle being drawn into the flow field at the rear of the vehicle, thereby improving the flow field at the side and rear of the vehicle and reducing the vehicle's drag coefficient.

[0005] An embodiment of this utility model also proposes a vehicle.

[0006] The vehicle side panel of this utility model has an air duct that extends along the front-rear direction of the vehicle side panel. The air duct has an air inlet and an air outlet. The air inlet is located in front of the air outlet, and the air outlet is arranged near the taillights of the vehicle.

[0007] According to the embodiment of the present invention, the side panel of the vehicle body extends along the front-rear direction of the side panel. When the vehicle is in motion, the airflow can enter the airflow through the air inlet and be discharged through the air outlet under the guidance of the airflow. Since the air outlet is arranged close to the taillights of the vehicle, the airflow discharged from the air outlet can form an air wall in the area of ​​the taillights of the vehicle. This can prevent the airflow from the side and upper part of the vehicle from being drawn into the flow field of the rear of the vehicle, thereby improving the airflow separation effect, improving the flow field of the side and rear of the vehicle, reducing the drag coefficient of the vehicle, and thus improving the vehicle's range.

[0008] In some embodiments, the air duct includes a first air duct and a second air duct connected together, the air inlet is located on the front side of the first air duct, the air outlet is located on the rear side of the second air duct, and in a projection orthogonal to the extension direction of the first air duct, the cross-sectional profile of the first air duct opens to the side of the outer wall of the vehicle side panel.

[0009] In some embodiments, the first air duct includes a first sidewall, a second sidewall, and a bottom wall, wherein the first sidewall and the second sidewall are respectively arranged on opposite sides of the bottom wall.

[0010] In some embodiments, the distance between the first sidewall and the second sidewall gradually increases along the flow direction of the airflow in the first duct.

[0011] In some embodiments, the junction of either the first sidewall or the second sidewall with the bottom wall has a first arc-shaped guide angle, which gradually decreases along the flow direction of the airflow in the first air duct.

[0012] In some embodiments, the height of the first sidewall and the height of the second sidewall gradually increase along the flow direction of the airflow in the first air duct.

[0013] In some embodiments, at least one of the first sidewall and the second sidewall has a second rounded corner at the contact position with the outer wall of the vehicle side panel, and the radius of the second rounded corner is R2, wherein 1mm≤R2≤2mm.

[0014] In some embodiments, at the junction of the first air duct and the second air duct, the distance between the first sidewall and the second sidewall is W, the height of either the first sidewall or the second sidewall is D, and the extension length of the first air duct in the front-back direction is L, wherein W, D and L satisfy at least one of the following conditions: 4D≤W≤6D, L≥2W.

[0015] In some embodiments, the cross-sectional profile of the second air duct is a closed ring within a projection orthogonal to the extension direction of the second air duct.

[0016] In some embodiments, in the direction of airflow within the second air duct, the height dimension of the second air duct gradually decreases along the vertical direction of the vehicle side panel.

[0017] In some embodiments, in the direction of airflow within the second air duct, the width of the second air duct gradually increases along the left-right direction of the vehicle body side panel.

[0018] In some embodiments, the cross-sectional profile of the air outlet is a closed ring, and the air outlet extends along the left and right directions of the vehicle body side panel.

[0019] In some embodiments, the vehicle side panel has a taillight mounting portion, and the air vent is located above the taillight mounting portion.

[0020] In some embodiments, the vehicle side panel includes a side panel body and an air duct shell, wherein the air duct shell is disposed inside the side panel body and together with the side panel body to form the air duct.

[0021] In some embodiments, the duct housing is detachably connected to the side panel body.

[0022] In some embodiments, the vehicle side panel is a one-piece molded part.

[0023] Another embodiment of the vehicle of the present invention includes a body side panel as described in one of the embodiments of the present invention.

[0024] According to the vehicle of this utility model embodiment, since the air duct extends along the front-rear direction of the side panel of the vehicle body, when the vehicle is in motion, the airflow can enter the air duct from the air inlet and be discharged from the air outlet under the guidance of the air duct. Since the air outlet is arranged close to the taillights of the vehicle, the airflow discharged from the air outlet can form an air wall in the area of ​​the taillights of the vehicle. This can prevent the airflow from the side and rear of the vehicle from being drawn into the flow field at the rear of the vehicle, thereby improving the airflow separation effect, improving the flow field at the side and rear of the vehicle, reducing the drag coefficient of the vehicle, and thus improving the vehicle's range.

[0033] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. 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.

[0034] The following is a reference appendix. Figures 1 to 7 This invention describes a vehicle body side panel and a vehicle according to an embodiment of the present invention.

[0035] like Figures 1 to 7 As shown, the side panel of the vehicle body in this embodiment of the utility model is provided with a wind duct 1. The wind duct 1 extends along the front and rear direction of the side panel of the vehicle body. The wind duct 1 has an air inlet 101 and an air outlet 102. The air inlet 101 is located in front of the air outlet 102, and the air outlet 102 is arranged close to the taillight 4 of the vehicle.

[0036] According to the embodiment of the present invention, the side panel of the vehicle body extends along the front-rear direction of the side panel. When the vehicle is in motion, the airflow can enter the airflow through the air inlet 101 and be discharged through the air outlet 102 under the guidance of the airflow 1. Since the air outlet 102 is arranged close to the taillight 4 of the vehicle, the airflow discharged from the air outlet 102 can form an air wall in the area of ​​the taillight 4 of the vehicle. This can prevent the airflow from the side and upper part of the vehicle from being drawn into the flow field of the rear of the vehicle, thereby improving the airflow separation effect, improving the flow field of the side and rear of the vehicle, reducing the drag coefficient of the vehicle, and thus improving the vehicle's range.

[0037] Optionally, such as Figure 3 and Figure 7 As shown, the air duct 1 includes a first air duct 11 and a second air duct 12 connected together. An air inlet 101 is located at the front of the first air duct 11, and an air outlet 102 is located at the rear of the second air duct 12. Figure 4 As shown, in the projection orthogonal to the extension direction of the first air duct 11, the cross-sectional profile of the first air duct 11 opens to the outer wall of the vehicle side panel. It can be understood that the cross-sectional profile of the first air duct 11 has an opening (i.e., the cross-sectional profile is not closed), and the opening is arranged to the outer side of the vehicle side panel.

[0038] This allows more airflow to enter the second airflow 12 under the guidance of the first airflow 11, which helps to increase the airflow velocity in the second airflow 12, further improving the airflow separation effect at the side and rear of the vehicle and reducing the vehicle's drag coefficient.

[0039] Optionally, such as Figure 4 As shown, the first air duct 11 includes a first side wall 111, a second side wall 112, and a bottom wall 113. The first side wall 111 and the second side wall 112 are respectively arranged on opposite sides of the bottom wall 113. By adopting the above-described structure for the first air duct 11, the side panel of the vehicle body in this embodiment of the present invention allows more airflow to enter the second air duct 12 under the guidance of the first air duct 11.

[0040] It is understandable that when the airflow passes through the area of ​​the first side wall 111 and the second side wall 112 and enters the first air duct 11, it can generate a vortex. This vortex will further drive the surrounding airflow into the first air duct 11, so that the airflow can accelerate into the opening area of ​​the first air duct 11.

[0041] like Figure 2 As shown, along the flow direction of the airflow within the first air duct 11, the distance between the first sidewall 111 and the second sidewall 112 gradually increases. When the airflow enters the first air duct 11, the gradual increase in the distance between the first sidewall 111 and the second sidewall 112, i.e., the gradual expansion of the first air duct 11, can eliminate eddies, allowing the airflow to accelerate into the opening area of ​​the first air duct 11.

[0042] Optionally, such as Figure 2 and Figure 4 As shown, the contact position between either the first side wall 111 or the second side wall 112 and the bottom wall 113 has a first arc-shaped guide angle 1101. The first arc-shaped guide angle 1101 gradually decreases along the flow direction of the airflow in the first air duct 11, thereby improving the airflow guiding effect and reducing air resistance.

[0043] For example, the radius R1 of the first arc guide angle 1101 gradually transitions from ∞ to 10 mm to further improve the airflow guiding effect and reduce air resistance.

[0044] Optionally, along the flow direction of the airflow in the first air duct 11, the height of the first side wall 111 and the height of the second side wall 112 gradually increase, thereby improving the airflow guiding effect so that more airflow can enter the second air duct 12 under the guidance of the first air duct 11, and also helping to increase the airflow velocity.

[0045] Optionally, such as Figure 4As shown, at least one of the first sidewall 111 and the second sidewall 112 has a second rounded bevel angle 1102 at the contact position with the outer wall of the vehicle side panel. The radius of the second rounded bevel angle 1102 is R2, where 1mm ≤ R2 ≤ 2mm. For example, R2 can be 1mm, 1.5mm, or 2mm. Thus, when the airflow passes through the area of ​​the first sidewall 111 and the second sidewall 112 and enters the first air duct 11, it can further generate vortices. These vortices will further drive the surrounding airflow into the first air duct 11, so that the airflow can accelerate into the opening area of ​​the first air duct 11.

[0046] Optionally, such as Figure 2 As shown, at the junction of the first air duct 11 and the second air duct 12, the distance between the first side wall 111 and the second side wall 112 is W, the height of either the first side wall 111 or the second side wall 112 is D, and the extension length of the first air duct 11 in the front-back direction is L. Wherein, W, D and L satisfy at least one of the following conditions: 4D≤W≤6D, L≥2W.

[0047] For example, W can be 4D, 4.5D, 5D, 5.5D, or 6D. L can be 2W, 3W, or 4W.

[0048] By adopting the above-mentioned parameter ranges for W, D, and L of the vehicle body side panel in the embodiment of this utility model, the rationality of the air duct 1 structure design can be improved, which is conducive to reducing wind resistance, increasing the airflow velocity in the second air duct 12, ensuring the airflow separation effect at the side and rear of the vehicle, and reducing the vehicle's drag coefficient.

[0049] Optionally, such as Figure 5 As shown, within the projection orthogonal to the extension direction of the second air duct 12, the cross-sectional profile of the second air duct 12 is a closed ring. This allows the airflow within the first air duct 11 to converge into the second air duct 12, which helps increase the airflow velocity as it passes through the second air duct 12. This allows the airflow to form an air wall when discharged from the air outlet 102, preventing the airflow from the sides and top of the vehicle from being drawn into the rear flow field. This improves airflow separation, enhances the flow field at the sides and rear of the vehicle, and reduces the vehicle's drag coefficient.

[0050] Optionally, such as Figure 7 As shown, in the airflow direction within the second air duct 12, the height dimension of the second air duct 12 gradually decreases along the vertical direction of the vehicle side panel. This increases the airflow velocity when the airflow exits from the second air duct 12, which helps to ensure the airflow separation effect at the side and rear, and reduces the vehicle's drag coefficient.

[0051] like Figure 6As shown, in the direction of airflow within the second air duct 12, the width of the second air duct 12 gradually increases along the left and right directions of the vehicle side panel. This increases the airflow coverage area when the airflow exits from the second air duct 12, further preventing the airflow from the side and upper parts of the vehicle from being drawn into the rear flow field, which helps to ensure the airflow separation effect at the side and rear, and reduces the vehicle's drag coefficient.

[0052] For example, in the direction of airflow within the second air duct 12, the cross-sectional area of ​​the second air duct 12 gradually increases, thereby improving the diffusion effect of the airflow.

[0053] Optionally, the cross-sectional profile of the air outlet 102 is a closed ring, and the air outlet 102 extends along the left and right directions of the vehicle side panel. This can increase the jet range of the airflow discharged from the air outlet 102, further blocking the airflow from the side and upper part of the vehicle from being drawn into the flow field at the rear of the vehicle, thereby improving the airflow separation effect, improving the flow field at the side and rear of the vehicle, and reducing the drag coefficient of the vehicle.

[0054] For example, such as Figure 1 As shown, the vehicle side panel has a taillight mounting portion 21, and an air vent 102 is located above the taillight mounting portion 21. Because the taillight 4 has a relatively rounded shape, the airflow passing through it may not separate completely and could be drawn into the rear airflow field. However, the vehicle side panel of this embodiment, by placing the air vent 102 above the taillight mounting portion 21, can prevent the side and upper airflow of the taillight 4 from being drawn into the rear airflow field, thus helping to reduce the vehicle's drag coefficient.

[0055] Optionally, such as Figure 3 As shown, the vehicle body side panel includes a side panel body 2 and an air duct shell 3. The air duct shell 3 is located inside the side panel body 2 and together with the side panel body 2, forms an air duct 1. This simplifies the forming method of the air duct 1 and makes it easy to process and manufacture.

[0056] For example, the duct housing 3 is detachably connected to the side panel body 2, thereby facilitating the disassembly, assembly, and replacement of the duct housing 3 and the side panel body 2. For instance, the duct housing 3 and the side panel body 2 can be connected by snap-fit, screw-fit, or riveting.

[0057] In other examples, the vehicle body side panels are integrally molded parts, which reduces the number of parts to be assembled and helps improve assembly efficiency.

[0058] Another embodiment of the vehicle of this utility model includes the side panel of the vehicle body of this utility model. The technical effects of the vehicle of this utility model embodiment are the same as the technical effects of the side panel of the vehicle body of this utility model, and will not be described in detail here.

[0059] The vehicle in this embodiment of the present invention uses the side panel of the vehicle body as described above. Through simulation analysis and calculation, the air duct 1 can reduce the vehicle's drag coefficient by 0.012, thereby improving the vehicle's aerodynamic performance and increasing its range.
