[0040] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0041] The front of a car needs a shroud to connect the air intake grille and the cooling module, serving both to guide airflow and provide a seal. Existing shroud designs neglect the impact of their structure on the internal flow field, easily leading to chaotic flow, eddies, noise, and increased system drag. Existing shroud structures, such as... Figure 7 and Figure 8 .

[0042] Therefore, the present invention provides a wind deflector and a car that can solve the above problems, which will be described in detail below.

[0043] Please refer to Figures 1 to 4The air guide shroud includes a shroud panel 1 and guide strips 12. The shroud panel 1 includes a first arc-shaped segment 10 and a second arc-shaped segment 11. The ends of the first arc-shaped segment 10 and the second arc-shaped segment 11 are connected to form an "S"-shaped arc plate. The first arc-shaped segment 10 is close to the air inlet end, and the convex surface of the first arc-shaped segment 10 faces the side through which the airflow passes. When the incoming airflow contacts the inner wall of the first arc-shaped segment 10 of the shroud panel 1 and continues to move forward, the convex surface of the first arc-shaped segment 10 faces inward, thus avoiding the generation of vortices and the noise caused by vortices. The guide strips 12 are disposed on the inner wall of the shroud panel 1 and are arranged along the direction of the incoming airflow. The guide strips 12 divide and guide the incoming airflow, avoiding flow field chaos in the direction of travel. The air guide shroud of this embodiment optimizes the flow field inside the air guide shroud and reduces the resistance of the system.

[0044] There are multiple guide strips 12, which are arranged at intervals and parallel to each other on the inner side of the cover panel 1. The long side of the guide strip 12 extends in the same direction as the airflow direction. The long side of the guide strip 12 can extend parallel to the airflow direction or be inclined. The guide strip 12 can be straight or curved.

[0045] Optionally, the outer wall of the cover panel 1 is provided with crisscrossing arched strips 14. The arched strips 14 are integrally formed with the cover panel 1. The arched strips 14, the "S"-shaped cover panel 1, and the guide strips 12 provided on the inner side of the cover panel 1 can further increase the strength and reliability of the structure without adding reinforcing ribs.

[0046] The air guide hood also includes a left end plate 2 and a right end plate 3, which are respectively connected to the left and right sides of the hood panel 1. The left end plate 2, the right end plate 3, and the hood panel 1 together form an air inlet cavity 13, in which the incoming airflow flows. The width of the hood panel 1 gradually increases on the side closer to the incoming airflow, making the inlet of the air inlet cavity 13 flared out to increase the air intake volume.

[0047] In this embodiment, the left end plate 2 of the cover is an arc plate, with one side of the convex surface of the arc plate facing the air inlet cavity 13. The side cross-sectional shape of the arc plate is adapted to the shape of the left side of the cover panel 1 to facilitate connection with the cover panel 1. Of course, if the right side of the cover panel 1 is symmetrical to the left side, the right end plate 3 of the cover can also be set as an arc plate, with one side of the convex surface of the arc plate facing the air inlet cavity 13 to facilitate connection with the cover panel 1 and form a gradually converging trumpet-shaped air inlet with the cover panel 1.

[0048] In other embodiments, the left end plate 2 and the right end plate 3 of the cover can also be other shapes. Their specific shapes need to be determined according to the side shape of the cover panel 1. The corresponding left end plate 2 and right end plate 3 of the cover can also be designed according to special requirements.

[0049] The left end plate 2, the right end plate 3, and the cover panel 1 can be connected by bonding, welding, screws / bolts, mortise and tenon joints, or integral molding. In this embodiment, the left end plate 2, the right end plate 3, and the cover panel 1 are integrally molded, which has good structural integrity and is not easy to leak air or be damaged.

[0050] Optionally, to further increase the airflow velocity and volume of the air inlet cavity 13, guide vanes 4 are provided on both the left end plate 2 and the right end plate 3 of the cover. The guide vanes 4 are used to guide more airflow into the air inlet cavity 13. The shape of the guide vane 4 can be a rectangular plate or a curved plate. The guide vane 4 has a first side and a second side facing each other. The first side of the guide vane 4 is connected to the left end plate 2 and / or the right end plate 3 of the cover, and the second side extends outward away from the air inlet cavity 13, with the extension direction from the first side to the second side, and the angle formed by the extension direction and the airflow is less than or equal to 90°. Of course, the guide vane 4 can also be other shapes, which are not listed here.

[0051] In this embodiment, the air guide shroud also includes two mounting flanges 5, which facilitate the installation and fixation of the air guide shroud. One mounting flange 5 is connected to the left end plate 2 of the shroud, and the other mounting flange 5 is connected to the right end plate 3 of the shroud. Specifically, one mounting flange 5 is perpendicular to the left end plate 2 and connected to the lower end of the left end plate 2, and the other mounting flange 5 is also perpendicular to the right end plate 3 and connected to the lower end of the right end plate 3.

[0052] Continue to refer to Figure 1 To facilitate quick connection of the air deflector to the front of the vehicle, multiple snap-fit ​​buckles 50 are provided on the mounting flange 5, where "multiple" refers to two or more. In this embodiment, the head of the snap-fit ​​buckle 50 is wedge-shaped, serving as a guide during insertion. The head of the snap-fit ​​buckle 50 is provided with a stop, and the front of the vehicle has a matching insertion hole. Inserting the snap-fit ​​buckle 50 into the insertion hole connects the air deflector to the front of the vehicle. In this embodiment, the upper end of the snap-fit ​​buckle 50 is connected to the lower surface of the mounting flange 5, giving the snap-fit ​​buckle 50 a certain degree of elasticity. When removing the snap-fit ​​buckle 50 from the insertion hole, it is only necessary to bend the snap-fit ​​buckle 50.

[0053] Optionally, reinforcing ribs 8 are provided between the mounting flange 5 and the left end plate 2 of the cover, and between the mounting flange 5 and the right end plate 3 of the cover, and the number of reinforcing ribs 8 is multiple. One side of the reinforcing rib 8 is connected to the upper surface of the mounting flange 5, and the other side is connected to the outer side of the left end plate 2 or the right end plate 3 of the cover, thereby playing a reinforcing role and increasing the overall structural strength of the air guide cover.

[0054] In this embodiment, the air guide cover also includes a docking flange plate 6, which is connected to the cover panel 1, the left end plate 2, the right end plate 3, and the mounting flange plate 5. The docking flange plate 6 is used to dock with the air intake grille.

[0055] Specifically, the left end of the mating flange 6 is connected to the left end plate 2 of the cover, and the right end of the mating flange 6 is connected to the right end plate 3 of the cover. A connecting post 61 is connected to the middle of the mating flange 6, and the other end of the connecting post 61 is connected to the inner side wall of the cover panel 1. The left and right ends of the mating flange 6 are also connected to the mounting flange 5 near the middle, thereby connecting the mating flange 6 with the cover panel 1, the left end plate 2 of the cover, the right end plate 3 of the cover and the mounting flange 5 together, resulting in a strong overall structure.

[0056] Since most of the air guide covers are made of plastic, a certain amount of deformable space needs to be reserved to increase the reliability of the connections between the various components of the air guide cover. Therefore, a locking block 60 is provided on the mating flange plate 6, and multiple locking blocks 60 are arranged along the edge of the mating flange plate 6 to form a serrated shape; multiple slots 7 are provided on the left end plate 2, the right end plate 3 of the cover, and the mounting flange plate 5. The multiple slots 7 are adapted to the locking blocks 60, and the locking blocks 60 are inserted into the slots 7 to increase the reliability of the connection.

[0057] Optionally, multiple locking blocks 60 are also provided on the edge of the air guide plate 4, and corresponding locking slots 7 are provided on the left end plate 2 and the right end plate 3 of the cover. The multiple locking blocks 60 are engaged in the multiple locking slots 7, so that the air guide plate 4 is reliably connected to the left end plate 2 and the right end plate 3 of the cover.

[0058] refer to Figure 5 and Figure 6 , Figure 5 A schematic diagram of the flow field simulated using an existing air guide shield; Figure 6 This is a schematic diagram of the flow field simulated using the air guide shroud of this embodiment. The shroud panel 1 of this embodiment is set in an "S" shape, and a simulation model is established to simulate the flow field for comparison. Figure 5 and Figure 6 It can be seen that the flow field inside the existing air guide shroud is prone to forming vortices near the air inlet and the shroud panel 1. This is because the air inlet grille changes the direction of the incoming airflow. In this embodiment, by changing the shape of the shroud panel 1, vortices are avoided from being generated inside the shroud panel 1. Since the generation of vortices increases the system resistance, avoiding the generation of vortices indirectly reduces the system resistance.

[0059] An embodiment of this utility model also provides an automobile, including the above-mentioned air deflector, which has all the functions of an air deflector.

[0060] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
