[0027] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.
[0028] Reference below Figure 1-Figure 4 The spoiler structure 100 according to the embodiment of the present invention is described. Furthermore, the present invention also provides a front cover 1000 , and the present invention also provides a vehicle.
[0029] Reference Figure 1-2 As shown, the spoiler structure 100 of the embodiment of the utility model includes a plurality of first spoilers 10 arranged at intervals, the plurality of first spoilers 10 are arranged in columns along a first direction and in rows along a second direction, and the first direction and the second direction are arranged at an angle.
[0030] Specifically, the spoiler structure 100 is arranged on vehicle components. For example, the spoiler structure 100 can be arranged on components such as a bumper, a side door panel, a front mask 1000, a rearview mirror and an underbody guard plate. The utility model is described in detail below using the front mask 1000 as an example, but is not limited to the front mask 1000.
[0031] The spoiler structure 100 is arranged on the outer surface of the windward component (such as the front mask 1000) of the freight vehicle. Preferably, it is arranged at the bends of the outer surfaces of the left and right sides of the front mask 1000, and the curvature of the spoiler structure 100 is arranged along the curvatures of the two sides of the front mask 1000. A plurality of first spoilers 10 are arranged on the spoiler structure 100, and the plurality of first spoilers 10 are arranged at intervals in the first direction of the spoiler structure 100, and the plurality of first spoilers 10 are arranged at intervals in the second direction, so that the first spoilers 10 are arranged in a matrix on the front mask 1000 of the freight vehicle. It can be understood that when the spoiler structure 100 is arranged on the windward component, the first direction and the second direction can be defined according to actual conditions. For example: the first direction and the second direction can be arranged vertically, such as the first direction can be the up-down, left-right or front-to-back direction, and the corresponding second direction can be the front-to-back, up-down or left-to-right direction; the first direction and the second direction can also be arranged at an angle. Taking the front mask 1000 as an example, the first direction is the up-down direction of the front mask 1000, and the second direction extends in an arc shape in the left-right direction and the front-to-back direction of the front mask 1000, that is, there is an angle between the first direction and the second direction, and as the second direction extends, the angle between the two gradually changes, and the angles at different positions are different, which has a better effect on disturbing the airflow, thereby further reducing the drag coefficient; the first spoiler 10 of each row and column is arranged along the curvature of the spoiler structure 100, and will not affect the curvature of the front mask 1000 of the vehicle.
[0032] After the first spoiler 10 is provided, the area of the front mask 1000 is increased relative to the original position. The distance that the same airflow needs to travel to flow through the first spoiler 10 increases, so the airflow velocity will become faster. When the airflow velocity increases, its pressure will decrease. Therefore, a negative pressure area will be formed at the position of the first spoiler 10. Since the airflow will move from the high-pressure area to the low-pressure area, the airflow around the first spoiler 10 will move toward the first spoiler 10. In this way, the first spoiler 10 can effectively guide the airflow, strengthen the airflow to flow along the wall at the arc positions on both sides of the front mask 1000, and weaken the airflow separation on both sides of the front mask 1000. At the same time, due to the addition of the first spoiler 10, the distribution of the airflow around the vehicle body is changed, while reducing the drag coefficient, the dust pollution on both sides of the vehicle body surface is improved.
[0033] Among them, the windward projection area of the first spoiler 10 in the same row gradually increases. The windward projection area refers to the projection area on the windward surface of the component. For the vehicle exterior, the windward surface is the outer surface of the exterior. When the outer surface of the exterior is a plane, the windward surface is a plane. When the outer surface of the exterior is a curved surface, the windward surface is a curved surface. In other words, the first spoiler 10 gradually increases from top to bottom. The first spoiler 10 on the spoiler structure 100 can effectively guide the airflow. When the vehicle is running at high speed, the airflow is strengthened to flow along the outer surface of both sides of the front mask 1000, so that it forms a tighter flow layer, weakens the separation of the airflow on both sides, reduces the generation of turbulence, and thus reduces the wind resistance of the vehicle when it is running. In this way, the vehicle drag coefficient can be reduced without adding parts, and the weight and manufacturing cost of the whole vehicle will not be increased.
[0034] Therefore, by using the spoiler structure 100 to guide the airflow, the degree of airflow separation of the vehicle body can be better controlled, energy loss can be reduced, and the wind resistance of the vehicle when driving can be reduced without adding components, and the weight and manufacturing cost of the whole vehicle are relatively low.
[0035] Reference Figure 2 As shown, the spoiler structure 100 further includes a plurality of second spoilers 11 arranged at intervals, and the plurality of second spoilers 11 are arranged in columns along the first direction and in rows along the second direction.
[0036] Similar to the first spoiler 10, a second spoiler 11 is also provided on the spoiler structure 100. The second spoiler 11 is also arranged in a matrix. Multiple rows of second spoilers 11 are spaced apart in the first direction of the spoiler structure 100, and multiple columns of second spoilers 11 are spaced apart in the second direction. The second spoilers 11 in each row and column are arranged as the curvature of the spoiler structure 100 changes, and will not affect the curvature of the front cover 100 of the vehicle.
[0037] Each row of first spoilers 10 is located between two adjacent rows of second spoilers 11, and each column of first spoilers 10 is located between two adjacent columns of second spoilers 11. That is, in the first direction of the spoiler structure 100, the second spoiler 11-first spoiler 10-second spoiler 11-first spoiler 10 are arranged in a cycle. Since different spoilers have different effects on the air pressure nearby, the air pressure will affect the air flow rate near the spoiler. The first spoiler 10 and the second spoiler 11 are alternately arranged, which will generate different degrees of negative pressure, so that the airflow flows more closely to the vehicle body, and the airflow around the vehicle body can be better controlled, and the wind resistance of the vehicle can be further reduced.
[0038] Reference Figure 2As shown, the windward projection area of the second spoilers 11 in the same row from top to bottom on the spoiler structure 100 remains unchanged. That is, the size of the second spoilers 11 in the same row remains unchanged, and the second spoilers 11 are also used to guide the flow of air. When the vehicle is running at high speed, the second spoilers 11 cause the surrounding airflow to produce a negative pressure effect, and the airflow flows along the outer surfaces of both sides of the front mask 1000, forming a more compact flow layer, weakening the separation of the airflow on both sides, reducing the generation of turbulence, and thus reducing the wind resistance of the vehicle when running.
[0039] Reference Figure 2 As shown, the windward projection area of the first spoiler 10 is not less than the windward projection area of the second spoiler 11. That is, the smallest windward projection area of the first spoiler 10 is not less than the windward projection area of the second spoiler 11. In the up-down direction of the spoiler structure 100, the first spoiler 10 and the second spoiler 11 are arranged in a staggered manner, which is beneficial to reducing the wind resistance coefficient of the vehicle.
[0040] Reference Figure 2 As shown, the windward projection area of the first spoilers 10 in the same row gradually increases and then gradually decreases; and / or, the windward projection area of the second spoilers 11 in the same row remains unchanged.
[0041] Specifically, the windward projection area of the first spoiler 10 is the largest at the turning point of the front cover 1000 of the vehicle, and the area of the first spoiler 10 extending to both sides gradually decreases. The turning point where the front of the vehicle meets the vehicle body is more likely to produce air flow separation and turbulence. When the airflow flows through the front end of the vehicle body, it will be hindered by the turning point and cause turbulence and turbulence, resulting in increased air resistance. Therefore, setting the first spoiler 10 with the largest windward projection area in this area can enhance the ability to control the airflow and reduce the impact of wind resistance on vehicle driving.
[0042] Moreover, the windward projection area of the second spoiler 11 in the same direction does not change, and the difference in windward projection area between the first spoiler 10 and the second spoiler 11 is further increased, so the effect of controlling airflow separation and reducing turbulence is better.
[0043] Also, the windward projection shape of the first spoiler 10 is one of a circle, an ellipse, a triangle and a rectangle, and the windward projection shape of the second spoiler 11 is one of a circle, an ellipse, a triangle and a rectangle; and / or, the first spoiler is one of a pit, a protrusion and a groove, and the second spoiler 11 is one of a pit, a protrusion and a groove.
[0044] In this embodiment, the first spoiler 10 and the second spoiler 11 are circular pits that are recessed inward on the outer surfaces of both sides of the front mask 1000. The pits can produce a negative pressure effect by utilizing the principles of aerodynamics. When air flows through the pits, the shape of the pits will cause the surrounding air flow rate to increase, forming a low-pressure area. This low-pressure area will attract the surrounding air to flow downward, forming a tighter flow layer, reducing air separation and turbulence, thereby reducing aerodynamic resistance.
[0045] In addition, the design of the pits changes the distribution of airflow around the vehicle body, allowing the air to flow more closely along the vehicle body, reducing the area where air is separated at the rear of the vehicle, thereby reducing dust accumulation. It can also reduce airflow turbulence at the rear of the vehicle, reducing the chance of dust being stirred up, further reducing dust deposition, and improving dust pollution on both sides of the vehicle body surface.
[0046] In addition to the circular pit in the present embodiment, the projection of the first spoiler 10 on the spoiler structure 100 can also be one of an ellipse, a triangle and a rectangle, and the form of the first spoiler 10 can also be one of a protrusion and a groove, wherein the projection shape and form of the first spoiler 10 can be combined with each other, for example, an elliptical protrusion, a triangular pit or a rectangular groove, etc.
[0047] Similarly, the projection of the second spoiler 11 on the spoiler structure 100 can also be one of an ellipse, a triangle and a rectangle, and the form of the second spoiler 11 can also be one of a protrusion and a groove, wherein the projection shape and form of the second spoiler 11 can be combined with each other, for example, an elliptical protrusion, a triangular pit or a rectangular groove, etc.
[0048] Reference Figure 3 As shown, the first spoiler 10 is a hemispherical pit, the diameter of the hemispherical pit is D and the depth is H, and D and H respectively satisfy the relationship: 5mm≤D≤20mm, 1.5mm≤H≤3mm. That is, the diameter of the hemispherical pit is not less than 5mm and not more than 20mm, and the depth of the pit is not less than 1.5mm and not more than 3mm. According to the test results, the pit diameter and depth within the above range can reduce the vehicle drag coefficient to the greatest extent under the premise of manufacturing and molding.
[0049] The second spoiler 11 is also a hemispherical pit, and the diameter D is within the range of about 5 mm, ensuring that the diameter of the hemispherical pit of the first spoiler 10 is not less than the diameter of the hemispherical pit of the second spoiler 11. The diameter of the hemispherical pit of the second spoiler 11 remains unchanged, and the depth H of the second spoiler 11 can be the same as that of the first spoiler 10, that is, the depth of the pit is not less than 1.5 mm and not more than 3 mm.
[0050] Reference Figure 4As shown, the center distance between two adjacent first spoilers 10 or two adjacent second spoilers 11 is L, and L satisfies the relationship: 25mm≤L≤28mm. That is, the center distance between two adjacent first spoilers 10 or two adjacent second spoilers 11 is not less than 25mm and not more than 28mm. Since the pits are arranged at the arc positions on both sides of the front mask 1000, the distances between adjacent pits at different positions are different. The arc positions on both sides of the front mask 1000 have better airflow guidance capabilities. At the same time, due to the limitations of the process, the pit distance is within the range of 25mm to 28mm, and the distribution on the spoiler structure 100 is more reasonable.
[0051] Among them, the number of the first spoilers 10 in a row is a1, and the number of the second spoilers 11 in a row is a2, and a1 and a2 satisfy the relationship: 16≤a1<a2≤22. Since the size of the first spoilers 10 is larger than the second spoilers 11, the number of the first spoilers 10 in each row is less than the number of the second spoilers 11, and the number of the first spoilers 10 and the second spoilers 11 in each row is between 16 and 22. In the embodiment of the utility model, there are 18 first spoilers 10 in each row and 20 second spoilers 11 in each row.
[0052] According to the front mask 1000 of the embodiment of the second aspect of the utility model, spoiler structures 100 are arranged on the left and right sides of the front mask 1000, wherein the first direction is the up and down direction, the projection shape of the second direction on the horizontal plane is an arc shape and / or the projection shape of the second direction on the vertical plane parallel to the front and rear direction is an arc shape.
[0053] In this embodiment, the spoiler structure 100 is located at the bend of the left or right side of the front mask 1000, the corresponding first direction is set as the up and down direction of the front mask 1000, the second direction is set as the projection shape on the horizontal plane is arc-shaped, that is, the second direction extends in an arc-shaped manner in the left and right direction of the front mask 1000, and / or is set as the projection shape on the vertical plane parallel to the front and rear direction is arc-shaped, that is, the second direction extends in an arc-shaped manner in the front and rear direction of the front mask 1000, preferably, the second direction extends in an arc-shaped manner in both the left and right direction and the front and rear direction of the front mask 1000. Since there is an angle between the first direction and the second direction, and the angle between the two gradually changes with the extension direction of the second direction, the angles at different positions are different, so that the disturbance effect on the airflow is better, thereby further reducing the drag coefficient; the first spoiler 10 of each row and each column is set according to the curvature of the spoiler structure 100, and will not affect the curvature of the front mask 1000 of the vehicle.
[0054] The vehicle according to the third embodiment of the utility model includes a bumper, a front cover 1000, a side door panel, a rearview mirror, a bottom guard plate and a roof, and one or more of the bumper, the front cover 1000, the side door panel, the rearview mirror and the roof are provided with a spoiler structure 100. That is to say, the spoiler structure 100 is not limited to being provided on the outer surface of both sides of the front cover 1000 of the vehicle, but can also be provided at other positions such as the bumper, the side door panel, the rearview mirror and the roof, and can be provided separately or at any number of the above structures at the same time, so as to guide the flow of air, weaken the separation of air flow and thereby achieve the purpose of reducing the wind resistance coefficient of the vehicle.
