[0003] In the related art, the aerodynamic components that play a role in reducing resistance at the front end of an automobile are mostly air ducts and bottom spoilers. Among them, since the air ducts are arranged in a position directly facing the visible area of the field of vision, they will have a greater impact on the overall appearance texture of the vehicle. If the air ducts are removed, the wind resistance of the whole vehicle will increase, resulting in increased energy consumption. Summary of the Utility Model

[0005] The present application provides a front-end module of an automobile. The front-end module of the automobile includes a front bumper, a bottom guard plate, and a wind guiding plate. The front bumper and the bottom guard plate are arranged at intervals along the length direction of the vehicle body.

[0029] With the continuous improvement of people's living standards, automobiles, as a means of transportation, have been widely used. Among them, by reducing the resistance during driving, automobiles can improve the driving stability and safety.
[0030] In the related art, the aerodynamic components at the front end of the automobile that play a role in reducing resistance are mostly air ducts and bottom spoilers. Among them, since the air ducts are arranged opposite to the visible area of the field of vision, they will have a greater impact on the overall appearance texture of the vehicle. If the air ducts are cancelled, it will lead to an increase in the wind resistance of the whole vehicle, resulting in an increase in energy consumption.
[0031] Please refer to Figures 1-5 , this application provides an automobile front-end module 100, which includes a front bumper 10, a bottom guard plate (not shown in the figure), and a wind deflector 20. The front bumper 10 and the bottom guard plate are arranged at intervals along the length direction of the vehicle body. The wind deflector 20 is arranged below the front bumper 10 and is respectively connected to the front bumper 10 and the bottom guard plate. Among them, the wind deflector 20 extends in an arc shape. Along the length direction of the vehicle body and from the front bumper 10 to the bottom guard plate, the height of the wind deflector 20 from the ground shows a gradually decreasing trend.
[0032] It can be understood that in this application, by arranging the wind deflector 20 below the front bumper 10 and setting the wind deflector 20 as an arc-shaped structure, the airflow flowing through the bottom of the vehicle during the driving process can form a negative pressure area at the bottom of the vehicle when passing through the wind deflector 20, improving the driving stability of the vehicle. Moreover, the arc-shaped structure has a smooth transition, which can effectively avoid the generation of turbulence at the front end of the vehicle, thereby reducing the wind resistance, improving the energy utilization rate, and greatly reducing the energy consumption. At the same time, the traditional air duct structure is cancelled, which is beneficial to improving the overall appearance texture of the automobile.
[0033] Further, in an embodiment, along the width direction of the vehicle body and from the middle of the front bumper 10 to the end of the front bumper 10, the height of the wind deflector 20 from the ground shows a gradually increasing trend. In this way, the wind resistance can be further reduced, the energy utilization rate can be improved, and the energy consumption can be reduced.
[0034] In an embodiment, as Figures 2-5As shown, the air deflector 20 includes a main body portion 21 and a connecting portion 22. The connecting portion 22 is connected to at least a part of the peripheral side of the main body portion 21, and the connecting portion 22 is respectively connected to the front bumper 10 and the bottom guard plate. In this way, the structure of the air deflector 20 is simple, and it is easy to realize the connection between the air deflector 20, the front bumper 10 and the bottom guard plate.
[0035] Further, in one embodiment, as Figure 3 shown, the main body portion 21 includes an arc segment 211 and a transition segment 212. The arc segment 211 is arranged in an arc shape, the transition segment 212 surrounds the peripheral side of the arc segment 211, and the transition segment 212 is respectively connected to the arc segment 211 and the connecting portion 22. By providing the transition segment 212, it is convenient for the connection between the main body portion 21 and the connecting portion 22, and the transition segment 212 can form a cavity structure with a closed front end with the arc segment 211 and the connecting portion 22, so as to facilitate a better guiding effect on the air flow.
[0036] In one embodiment, as Figure 2 and Figure 4 shown, the arc segment 211 is along the length direction of the vehicle body and from the front bumper 10 to the bottom guard plate. The height of the arc segment 211 from the ground shows a gradually decreasing trend. And, in the direction away from the bumper, the inclination angle between the arc segment 211 and the horizontal plane gradually decreases.
[0037] Among them, the included angle range between the arc segment 211 and the horizontal plane can be set to 10° to 30°. In this way, a better flow guiding effect can be achieved, and it is easy to process the arc segment 211. For example, the included angle between the arc segment 211 and the horizontal plane can be set to 10°, 15°, 20°, 25° or 30°, etc., which are not listed one by one here.
[0038] It should be noted that the included angle between the arc segment 211 and the horizontal plane here refers to the included angle formed by the tangent of the arc surface of the arc segment 211 and the horizontal plane.
[0039] In one embodiment, as Figure 2 shown, along the height direction of the vehicle body, at least a part of the projection of the connecting portion 22 on the front bumper 10 coincides with the front bumper 10, and at least a part of the projection of the connecting portion 22 on the bottom guard plate coincides with the bottom guard plate. That is, the connecting portion 22 can overlap the front bumper 10 and the bottom guard plate along the height direction of the vehicle body, which not only increases the contact area, thus effectively improving the reliability of the connection, but also enables the transition segment 212 to cooperate with the front bumper 10 and the bottom guard plate, so that there is no obvious protrusion at the bottom of the vehicle, thereby further optimizing the vehicle aerodynamics.
[0040] Specifically, to achieve the connection between the air deflector 20, the front bumper 10, and the bottom guard plate, in one embodiment, a plurality of connection holes 201 arranged at intervals are formed in the connection portion 22. The vehicle front-end module 100 further includes a fastener (not shown in the figure). The fastener passes through the connection holes 201 to detachably connect the air deflector 20 to the front bumper 10 and the bottom guard plate. In this way, the disassembly and assembly of the air deflector 20 are facilitated, which is beneficial to subsequent maintenance and reduces the maintenance cost.
[0041] In one embodiment, the main body portion 21 and the connection portion 22 are of an integrally formed structure. In this way, the structural strength of the air deflector 20 is greatly improved, and the surface structure of the air deflector 20 is smoother.
[0042] In one embodiment, the air deflector 20 is a plastic part to reduce the cost of the air deflector 20, and the plastic is lighter, enabling vehicle lightweighting.
[0043] This application also provides a vehicle, which includes the vehicle front-end module 100 described in any one of the above embodiments. Specifically, the number of air deflectors 20 is set to two, and the two air deflectors 20 are spaced apart along the vehicle body width direction.
[0044] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0045] The above-described embodiments merely represent several implementation manners of this application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the patent protection scope of this application should be subject to the appended claims.
