Description

Technical Field

[0001] This disclosure relates to an air guidance device for a vehicle front-end module, a vehicle front-end module, and a vehicle. Background Technology

[0002] In vehicles, especially motor vehicles, a front-end module is typically installed behind the front grille to guide fresh outside air into the vehicle. The introduced air is primarily used to cool the vehicle's engine, battery, etc., after passing through the vehicle's cooling module, and / or to ventilate the vehicle's interior.

[0003] To achieve the aforementioned airflow guidance function, vehicle front-end modules are typically equipped with air guiding devices. However, a significant drawback of existing air guiding devices of this type is their excessive weight. This has a marked negative impact on modern vehicles that prioritize energy conservation and emission reduction, especially on electric vehicles where range is a critical factor. While some design solutions have been developed to reduce weight, these solutions often result in insufficient structural strength. This trade-off between weight and strength restricts the optimization of vehicle front-end module performance. Utility Model Content

[0058] Figure 1 An exploded view of a vehicle front-end module 4 according to this disclosure is shown. The figure shows three main components of the vehicle front-end module 4: an air guide device 1, a radiator 2, and a fan 3.

[0059] To enhance the material strength of air suspension systems, traditional designs typically employ high-density, high-strength materials or add substantial solid ribs to the surface to increase tensile and compressive strength. However, this results in a significant increase in the weight of the air suspension system and the vehicle's front-end module, which is detrimental to the energy efficiency of modern vehicles, particularly impacting the driving range of electric vehicles.

[0060] Figure 2 A perspective side view of an air guiding device according to the present disclosure is shown. The air guiding device 1 includes a peripheral wall that encloses an air passage having an air inlet 11 and an air outlet 12. A vehicle front-end module 4 is mounted on a vehicle, particularly a motor vehicle, not shown in the figure. Typically, the air inlet 11 of the air guiding device 1 is connected to the rear side of the air intake grille located at the front of the vehicle, while the air outlet 12 is connected to the radiator 2 of the vehicle front-end module 4. Specifically, under the action of the fan 3, air enters the air guiding device 1 from the air intake grille along the air passage in the intake direction X through the air inlet 11 and flows to the downstream radiator 2 through the air outlet 12.

[0061] A set of grooves is formed on at least one surface of the peripheral wall. Figure 2 The air guiding device 1 shown in the figure has multiple grooves on the upper surface of its air passage. This surface extends substantially parallel to the air intake direction X from the upper end of the air inlet 11, and then extends upward at a large angle to the upper end of the air outlet 12. Figure 4 .

[0062] The groove assembly includes a main groove 13 and a secondary groove, which extend intersecting with the main groove 13. This design effectively improves the strength of the air guiding device, solving the problem of insufficient strength in components with large areas and small thicknesses. Furthermore, this structure helps to reduce the internal volume of the air guiding device, increases the internal air pressure, and causes the incoming air to flow towards the radiator, thus improving the heat exchange performance of the downstream radiator.

[0063] Figure 3 A front view of the air guiding device according to the present disclosure along the air intake direction X is shown. As shown, the main groove 13 extends perpendicularly to the air intake direction X of the air passage. The groove group includes a plurality of main grooves 13 extending parallel to each other. Figure 2 and Figure 3As can be seen, three main grooves 13 are constructed sequentially from top to bottom, extending parallel to each other along the entire length (perpendicular to the intake direction X) of this surface of the air guide device 1. Of course, the number of main grooves 13 may differ from that shown here, for example, it may be in the range of 2 to 5.

[0064] like Figure 3 As shown, the secondary groove includes a first groove 14 extending perpendicularly to the main groove 13 and / or a second groove extending not perpendicularly to the main groove 13. The first groove 14 shown in the figure is located in the center of this surface of the air guiding device 1, although it could be positioned in other locations. One first groove 14 is shown in the figure, but other numbers are also possible. Furthermore... Figure 3 The image shows a second groove that does not extend perpendicularly to the main groove 13.

[0065] The second groove includes a first segment 15, which intersects with the first groove 14 at the end of the first groove 14, and extends from the point of intersection of the first segment 15 and the first groove 14 to the corners of the surface on both sides of the first groove 14. Figure 3 In the first groove 14, the first segment 15 on both sides of the first groove 14 intersects with the first groove 14 at the lower end in the first groove 14 and extends upward and outward to the two corners of this surface, thereby forming an inverted triangular structure.

[0066] The second groove further includes a second segment 16, which extends from the intersection of the second groove and the main groove 13 toward the air inlet 11. Figure 3 As can be seen, the second section 16 extends outward from the intersection of the second groove and the main groove 13 toward the air inlet 11 (i.e. downward in the figure).

[0067] exist Figure 3 As can be seen, the peripheral wall also includes two side surfaces 17, one of which is in Figure 4 The side view of the air guide device is shown, and this side can be constructed symmetrically to the side not shown. A lateral groove is formed on the side, extending parallel to the air intake direction for at least a portion of the length of the side. Figure 4 The diagram shows multiple lateral grooves, with the lowest lateral groove 171 extending along a portion of the length of this side along the air intake direction X. Above it are two upper lateral grooves 172, which extend substantially along the entire length of this side. These lateral grooves narrow the air intake channel from front to rear at the front of the vehicle, increasing the airflow velocity to improve the heat exchange performance of the radiator downstream of the air guide device.

[0068] As shown in the figure, both the main groove 13 and the secondary groove protrude into the air channel, thereby improving both strength and air guiding performance. The cross-section of these grooves can be V-shaped, U-shaped, or other shapes.

[0069] Furthermore, the wall thickness of the main groove 13 and the secondary groove is the same as the thickness of the peripheral wall. That is, the main groove 13 and the secondary groove are formed by recesses in the local surface of the peripheral wall itself. Compared to the solid reinforcing ribs used in the prior art, this design improves the tensile and compressive strength of the air guiding device without requiring additional materials.

[0070] Figure 5 A bottom view of the air guiding device according to this disclosure is shown. The bottom surface 18 of the peripheral wall of the air guiding device protrudes into the air passage between the air inlet 11 and the air outlet 12. The inwardly concave structure of the bottom surface reduces the internal volume of the air guiding device and thereby increases the internal air pressure of the air guiding device.

[0071] Figure 5 As can be seen, protruding ribs 181 extending in the air intake direction are constructed on the outer surface of the bottom surface 18 opposite to the air passage. These ribs ensure the structural strength of the air guiding device at the bottom. In the example shown in the figure, ten ribs are provided on the bottom surface, but other numbers of ribs can be provided depending on the size of the bottom surface.

[0072] The air guiding device 1 includes a support member 19, which is supported at the air inlet 11 between two opposing portions of the peripheral wall. Figure 6 A perspective view of the support area of ​​the air guiding device according to this disclosure is shown. This support increases the strength of the air guiding device 1 at the air inlet, preventing deformation of the air inlet. The position of the support 19 can be designed to divide the air inlet into two symmetrical parts.

[0073] Figure 6 The observation direction is from the air outlet towards the air inlet. The cross-section of the support member 19 is a semi-enclosed structure with an opening facing the air outlet 12. The semi-enclosed structure reduces the amount of material used in the support member while ensuring the necessary structural strength. The opening of the support member facing the air outlet 12 reduces the air intake resistance.

[0074] The support member 19 has a semi-circular cross-section, which further reduces air intake resistance.

[0075] The support member 19 is supported on the corresponding part of the peripheral wall by a triangular support rib 191. Figure 6The diagram shows triangular support ribs constructed at the upper and lower portions of the support member 19 where it connects to the peripheral wall. These ribs provide increased strength to the support member 19, thus offering a lightweight yet high-strength support for the air guide device, resulting in a more robust structure resistant to thermal deformation of the air inlet under hot air conditions. The triangular support ribs 191 extend from the two side walls of the support member 19 via bevels and connect to corresponding portions of the peripheral wall. The upper and lower triangular support ribs can have the same or different shapes, and can be designed in other forms.

[0076] The air inlet 11 and the air outlet 12 each have an air inlet sealing edge 111 and an air outlet sealing edge 121 formed on their peripheries by two-color injection molding. This allows for sealing through a simple design, reducing costs.

[0077] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure.
