Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts, in particular to a front wheel spoiler and a vehicle. Background Art

[0002] The driving resistance encountered by a vehicle during driving mainly includes rolling resistance, acceleration resistance, slope resistance and aerodynamic resistance. Among them, aerodynamic resistance refers to the resistance of airflow to the vehicle. Moreover, the aerodynamic resistance encountered by the vehicle when driving at high speed accounts for 60% to 80% of the driving resistance.

[0003] At present, more and more vehicles are using spoilers installed on the front wheels to reduce driving resistance. However, the existing front wheel spoilers are usually smooth sheet-shaped spoilers, which are easily deformed under the impact of airflow when the vehicle is running at high speed, which not only leads to poor drag reduction effect, but also easily leads to increased front axle lift, seriously affecting the aerodynamic performance and fuel economy of the vehicle.

[0025] It should be noted that the terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0026] Combination Figure 1 and Figure 4 As shown, an embodiment of the utility model provides a front wheel spoiler 100, including a board body 1, a plurality of spoiler strips 11 protruding from a windward surface 16 of the board body 1, the plurality of spoiler strips 11 are arranged at intervals and arranged from one end to the other end of the two oppositely arranged ends of the board body 1.

[0027] Specifically, the front wheel spoiler 100 is usually installed on the front bottom guard plate 200 located at the front side of the front wheel, and one front wheel spoiler 100 is usually installed at each of the left and right front wheels. Figures 1 to 4The front wheel spoilers 100 in the figure are all spoilers on the front side of the right front wheel 400. The board body 1 of the front wheel spoiler 100 is usually in an arc structure, and the whole is slightly tilted toward the rear and downward, that is, the lower surface of the board body 1 is tilted toward the rear and downward, and will be impacted by the airflow when the vehicle is running. The windward surface 16 of the board body 1 is the surface of the board body 1 that will be impacted by the airflow when the vehicle is running, so it is also the lower surface of the board body 1. Correspondingly, the leeward surface 17 of the board body 1 is the surface of the board body 1 that will not be impacted or relatively less impacted by the airflow when the vehicle is running, and it is also the upper surface of the board body 1. The spoiler strips 11 are arranged on the windward surface 16 of the board body 1, and a plurality of spoiler strips 11 are provided. The spoiler strips 11 are usually in the form of strip-shaped protrusions. Moreover, according to the structural dimensions of the board body 1, the lengths of the plurality of spoiler strips 11 may be the same or different. For example, if the board body 1 is rectangular, the lengths of the plurality of spoiler strips 11 are usually the same. If the board body 1 is trapezoidal, and the front and rear ends of the board body 1 are respectively the long side and the short side of the trapezoid, then the lengths of some of the plurality of spoiler strips 11 are usually the same, and the lengths of the other parts are different. If the board body 1 is Figure 1 The lengths of the spoiler strips 11 are usually different. The spoiler strips 11 may be as follows: Figure 1 As shown in the figure, the spoiler strips 11 are arranged at intervals along the left-right direction of the vehicle, or along the front-back direction of the vehicle, or along an oblique direction such as from the left front to the right rear or from the right front to the left rear, which is not specifically limited here. Regardless of the arrangement, the plurality of spoiler strips 11 are arranged from one end of the two opposite ends of the plate body 1 to the other end, for example Figure 1 As shown, a plurality of spoiler strips 11 are sequentially arranged from the left end to the right end of the board body 1 , so that the spoiler strips 11 cover the entire windward surface 16 of the board body 1 .

[0028] The front wheel spoiler 100 in this embodiment can be provided with a plurality of spoiler strips 11 arranged at intervals on the windward surface 16 of the plate body 1, and the plurality of spoiler strips 11 are arranged from one end of the two opposite ends of the plate body 1 to the other end, so that the windward surface 16 of the front wheel spoiler 100 is a non-smooth surface with concave and convex surfaces alternately arranged, so that when the airflow passes through the uneven windward surface 16 of the front wheel spoiler 100, a vortex can be formed, and the vortex can weaken the vortex caused by the rotation area of ​​the front wheel of the vehicle, thereby achieving the purpose of further reducing the aerodynamic resistance and improving the fuel economy and energy saving and emission reduction effect of the vehicle. At the same time, the airflow has a large flow velocity and a small air pressure when passing through the convex surface of the front wheel spoiler 100, and a small flow velocity and a large air pressure when passing through the concave surface, and finally forms a downward pressure, thereby reducing the front axle lift, increasing the ground adhesion of the vehicle, and ensuring the stability of the vehicle when driving at high speed. Moreover, the provision of the spoiler strip 11 can also improve the structural strength of the plate body 1, so that the front wheel spoiler 100 is not easily deformed due to the impact of airflow when the vehicle is running at high speed. Not only does it have a long service life, but it can also ensure that the front wheel spoiler 100 also has a good drag reduction effect when the vehicle is running at high speed.

[0029] Optionally, combined Figure 1 As shown, the protrusion height H of the spoiler strip 11 is ≤20 mm, and / or the distance L between two adjacent spoiler strips 11 is ≤20 mm.

[0030] It should be noted that the protruding height H of the spoiler strip 11 refers to the height of the spoiler strip 11 beyond the plate body 1 , which is also the size of the spoiler strip 11 in the Z-axis direction.

[0031] In the present embodiment, if the raised height H of the spoiler strip 11 is too large, the ground clearance of the vehicle at the front bottom protection plate 200 will be reduced, affecting the vehicle's passability. If the spacing L between two adjacent spoiler strips 11 is too large, the spoiler strips 11 are laid sparsely, which may reduce the vortex of the airflow passing through the front wheel spoiler 100, thereby reducing the drag reduction effect of the front wheel spoiler 100. Therefore, in the present embodiment, by setting the raised height H of the spoiler strip 11 within 20mm, and / or, setting the spacing L between two adjacent spoiler strips 11 within 20mm, it is ensured that the spoiler strip 11 plays its best spoiling role, thereby ensuring that the front wheel spoiler 100 has a good drag reduction effect.

[0032] In addition, in practical applications, the raised height H of the spoiler strip 11 and the spacing L between two adjacent spoiler strips 11 will not be set too small, and are usually controlled to be, for example, 4 mm or 5 mm or more. This is because if the raised height H of the spoiler strip 11 is too small, the vortex of the airflow passing through the front wheel spoiler 100 will be reduced. If the vortex is not reduced, the spoiler strips 11 need to be laid more densely, which makes the processing of the front wheel spoiler 100 difficult; if the spacing L between two adjacent spoiler strips 11 is too small, the spoiler strips 11 need to be laid more densely, which makes the processing of the front wheel spoiler 100 difficult.

[0033] Furthermore, combined with Figure 3 As shown, the cross section of the spoiler strip 11 is semicircular or semi-elliptical. The cross section of the spoiler strip 11 refers to the cross section of the spoiler strip 11 perpendicular to its extension direction. Compared with the spoiler strip 11 with a rectangular cross section, the spoiler strip 11 with a semicircular or semi-elliptical cross section has a better spoiler effect and drag reduction effect.

[0034] Optionally, combined Figure 1 As shown, the spoiler strip 11 extends from one end to the other end of the panel body 1 in the front-rear direction of the vehicle, and a plurality of spoiler strips 11 are arranged from one end to the other end of the panel body 1 in the left-right direction of the vehicle.

[0035] It should be noted that the front and rear directions of the vehicle are Figure 1 The X-axis direction is referred to as the front-to-back direction, and the left-to-right direction of the vehicle is Figure 1 The middle Y-axis direction is referred to as the left-right direction.

[0036] In this embodiment, the spoiler strips 11 are extended in the front-to-back direction and extend from the front end of the plate body 1 to the rear end of the plate body 1, and a plurality of spoiler strips 11 are arranged from the left end of the plate body 1 to the right end of the plate body 1. According to the relevant formula, for every 0.01 reduction in the aerodynamic drag coefficient, the fuel consumption is reduced by 0.05L / 100km. After testing, the front wheel spoiler 100 in this embodiment arranges the spoiler strips 11 in this way, which can reduce the drag coefficient by 0.02, and the fuel consumption is reduced by 0.1L / 100km, and the carbon dioxide emission is reduced by 13.856g / km, so that the front wheel spoiler 100 can improve the aerodynamic performance and fuel economy of the whole vehicle, achieve energy saving and emission reduction, and has high feasibility.

[0037] Optionally, combined Figure 2 and Figure 3 As shown, the front wheel spoiler 100 further includes a flange portion 2 integrally formed with the plate body 1 , the flange portion 2 is disposed at both ends of the plate body 1 along the left-right direction of the vehicle, and a spoiler strip 11 is also disposed on the flange portion 2 .

[0038] In this embodiment, according to the needs of practical application, the structures of the flanged portions 2 at the left and right ends of the plate body 1 can be the same or different, and the bending angles of the flanged portions 2 can also be the same or different. Figure 2 As shown, the flange portion 2 at the left end of the plate body 1 is bent upward, and the flange portion 2 at the right end of the plate body 1 is bent obliquely upward, that is, the bending angle of the flange portion 2 at the left end of the plate body 1 is greater than the bending angle of the flange portion 2 at the right end of the plate body 1. In this way, by arranging the flange portions 2 at the left and right ends of the plate body 1, and also arranging the spoiler strips 11 on the flange portions 2, a certain vortex can be generated when the airflow passes through the left and right ends of the plate body 1, thereby increasing the vortex of the airflow passing through the front wheel spoiler 100, so as to further weaken the vortex caused by the rotation area of ​​the front wheel of the vehicle, and further improve the drag reduction effect of the front wheel spoiler 100.

[0039] Optionally, combined Figure 1 and Figure 4 As shown, a first mounting hole 12 and a second mounting hole 13 are provided on the plate body 1 , and the plate body 1 is used to be detachably connected to the front bottom protection plate 200 at the first mounting hole 12 , and to be detachably connected to the front cabin bottom protection plate 300 at the second mounting hole 13 .

[0040] In this embodiment, the first mounting hole 12 and the second mounting hole 13 usually penetrate the plate body 1 in the up-down direction. In this way, during assembly, the front wheel spoiler 100 is bolted to the front bottom protection plate 200 at the first mounting hole 12, and the front wheel spoiler 100 is bolted to the front engine bottom protection plate 300 at the second mounting hole 13, so that the front wheel spoiler 100 is fixed on the front bottom protection plate 200 and the front engine bottom protection plate 300, thereby protecting the bottom of the vehicle body. At the same time, the front wheel spoiler 100 is extended backward to the front engine bottom protection plate 300 located behind the front bottom protection plate 200, and is bolted to the front engine bottom protection plate 300 at the second mounting hole 13, so that the front wheel spoiler 100 has a sufficient length in the X direction, ensuring that the front wheel spoiler 100 achieves the best drag reduction effect.

[0041] Furthermore, two first mounting holes 12 are usually provided, and one second mounting hole 13 is usually provided, and these three mounting holes are usually respectively provided at three vertices of the plate body 1 having a substantially triangular plate structure. In this way, the front wheel spoiler 100 is fixed to the front bottom protection plate 200 and the front engine room bottom protection plate 300 by using a three-point fixing method distributed in a triangular shape, thereby ensuring the stability of the installation and avoiding the rigidity problem caused by the excessive length of the front wheel spoiler 100.

[0042] Furthermore, the distance between the board body 1 and the front bottom protection plate 200 increases gradually along the front-rear direction of the vehicle.

[0043] In the present embodiment, after the front wheel spoiler 100 is installed on the front bottom guard plate 200, a cavity is formed between the plate body 1 and the front bottom guard plate 200, and the cavity has a notch at the rear end of the plate body 1, that is, the rear end of the cavity is open, so as to facilitate the active deformation of the front wheel spoiler 100 while achieving weight reduction (in this case, the front wheel spoiler 100 is usually made of soft rubber material).

[0044] Optionally, combined Figure 2 As shown, the leeward side 17 of the plate body 1 is convexly provided with a first boss 14 and a second boss 15 , the first mounting hole 12 is provided on the first boss 14 , and the second mounting hole 13 is provided on the second boss 15 .

[0045] In this embodiment, the first boss 14 and the second boss 15 are generally cylindrical structures, and the first mounting hole 12 and the second mounting hole 13 generally penetrate the first boss 14 and the second boss 15 respectively, so as to facilitate processing. Moreover, the arrangement of the first boss 14 and the second boss 15 makes the screw connection part of the plate body 1 thicker, so as to ensure the stability of the screw connection between the front wheel spoiler 100 and the front bottom protection plate 200 and the front engine room bottom protection plate 300; and, the plate body 1 as a whole is thicker in the screw connection part and thinner in other parts such as those that are easy to bump, which can not only achieve a certain degree of weight reduction, but also facilitate the thinner parts of the plate body 1 to be able to actively deform when encountering obstacles, so as to ensure that the vehicle passes the obstacles smoothly.

[0046] Optionally, the front wheel spoiler 100 is made of soft rubber.

[0047] In this embodiment, since the front wheel spoiler 100 is installed at the bottom of the front bottom guard plate 200 and is a part that is easily bumped, the front wheel spoiler 100 is usually made of a soft rubber material such as vulcanized rubber, so that the front wheel spoiler 100 has a certain elasticity. In this way, when the vehicle needs to pass through an obstacle during driving, the front wheel spoiler 100 can actively produce a large deformation under the action of external force to cope with most obstacles with higher hardness, thereby extending the service life of the front wheel spoiler 100.

[0048] Optionally, combined Figure 2 As shown, the front wheel spoiler 100 further includes reinforcing ribs 3 , which are arranged on the leeward side 17 of the board body 1 .

[0049] In this way, the reinforcing ribs 3 can be used to further improve the structural strength of the front wheel spoiler 100, ensuring that the front wheel spoiler 100 has both a certain elasticity and a certain rigidity when made of soft rubber material, thereby ensuring that the front wheel spoiler 100 can withstand the impact of airflow when the vehicle is traveling at high speed and can actively deform when subjected to a large external force.

[0050] Optionally, combined Figure 2As shown, the reinforcing rib 3 includes a first rib plate 31 and a second rib plate 32 , and the first rib plate 31 and the second rib plate 32 are alternately arranged.

[0051] In this embodiment, the first rib plate 31 and the second rib plate 32 may be arranged in a vertical cross arrangement or in a non-vertical cross arrangement. For example, as shown in FIG2 , the first rib plate 31 and the second rib plate 32 are arranged in a vertical cross arrangement, and the first rib plate 31 extends from the front end to the rear end of the plate body 1, and the second rib plate 32 extends from the left end to the right end of the plate body 1. In this way, by staggering the first rib plate 31 and the second rib plate 32, the reinforcing rib 3 is a mesh reinforcing rib structure, which can significantly improve the local structural strength of the front wheel spoiler 100.

[0052] Another embodiment of the present invention provides a vehicle, comprising the front wheel spoiler 100 as described above.

[0053] The vehicle in this embodiment further comprises a front bottom protection plate 200, a front engine bottom protection plate 300 and a front wheel, wherein a front wheel spoiler 100 is respectively provided at the left front wheel and the right front wheel 400, and the two front wheel spoilers 100 are respectively installed at the left and right ends of the bottom of the front bottom protection plate 200, and are detachably connected to the front bottom protection plate 200 at the first mounting hole 12, and the two front wheel spoilers 100 are usually also bolted to the left and right ends of the front engine bottom protection plate 300 at the second mounting hole 13. In addition, the beneficial effects of the vehicle in this embodiment relative to the prior art are the same as those of the above-mentioned front wheel spoiler 100, which will not be repeated here.

[0054] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
