Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and in particular to a vehicle body front end flow guide structure. Meanwhile, the utility model also relates to a vehicle provided with the vehicle body front end flow guide structure. Background Art

[0002] In the actual development process, due to the need for styling, the left and right headlights or fog lights on some car front bumpers are lower than the surface of the bumpers on both sides, thus forming a relatively obvious pit. During driving, the airflow will be diverted from the middle of the front bumper to both sides. When the diverted air flows to the pit, a high-pressure area is formed and obvious vortices are generated, increasing the wind resistance coefficient, thus affecting the vehicle's endurance and fuel economy.

[0003] Although existing vehicles choose to set up wind guide structures on both sides of the front bumper to guide the airflow direction at the front end of the car and alleviate the wind resistance pressure during the driving of the car, the guide effect of the existing wind guide structure is limited, resulting in the car still being subject to large wind resistance during driving, thereby adversely affecting the fuel economy of the entire vehicle. Utility Model Content

[0063] In addition, if Figure 4 and Fig.10 As shown in the figure, a groove 10 sunken in the air intake direction is formed at the connection position between the main body part 401 and the guide part 402, and the end of the decorative plate 8 close to the air intake channel 1 extends into the groove 10, thereby preventing light leakage between the decorative plate 8 and the decorative cover 4 and the problem of exposed connection structure, thereby achieving a better air guide effect.

[0064] Preferably, in this embodiment, an inserting portion and a clamping portion are provided between the guide portion 402 and the decorative plate 8. As the inserting portion inserts the guide portion 402 and the decorative plate 8, the clamping portion clamps and connects the guide portion 402 and the decorative plate 8. By connecting the guide portion 402 and the decorative plate 8 through the inserting portion and the clamping portion, the connection structure is simple, the connection operation is convenient, and the decorative plate 8 can be quickly disassembled and assembled.

The insertion of the guide part 402 and the decorative plate 8 is achieved by inserting each insertion plate 11 into the corresponding insertion hole 12. In addition, a clamping plate 13 is provided near the insertion hole 12 on the guide part 402. The clamping part includes a clamping hole 15 provided on the insertion plate 11, and a clamping protrusion 14 provided on the clamping plate 13. After the insertion plate 11 is inserted into place, the clamping protrusion 14 can be clamped in the clamping hole 15, thereby achieving the connection between the decorative plate 8 and the guide part 402.

[0066] As a preferred implementation, in this embodiment, a limiting rib 16 is provided on the decorative plate 8, and the limiting rib 16 abuts against the guide portion 402 and can limit the guide portion 402 from being separated from the engagement with the decorative plate 8. Figure 8 and Fig. 9 As shown in the figure, the limiting ribs 16 are arranged on the circumferential side of the decorative plate 8 and extend in the direction of the guide portion 402, and the limiting ribs 16 are multiple and arranged at intervals along the circumferential side of the decorative plate 8. When the snap-in protrusion 14 is snapped into the snap-in hole 15, the limiting ribs 16 can abut against the guide portion 402, thereby limiting the guide portion 402 from being detached from the snap-in connection with the decorative plate 8, thereby ensuring the connection stability between the decorative plate 8 and the guide portion 402.

[0067] Preferably, the decorative plate 8 is provided with a plurality of guide grooves 17 corresponding to the main body section 101, and the rear end of the guide groove 17 is arranged in a shape conforming to the edge of the main body section 101.

[0068] The decorative plate 8 specifically includes a protruding portion 801 located in the middle, bent portions 803 located at both ends along a preset direction, and a connecting portion 802 connected between the protruding portion 801 and the bent portion 803, and the protruding portion 801, the connecting portion 802 and the bent portion 803 surround and form the above-mentioned guide groove 17. The guide groove 17 is provided to improve the air intake effect and facilitate the airflow to be guided into the air intake channel 1, and the rear end of the guide groove 17 is arranged in accordance with the edge of the main section 101, so as to facilitate the smooth transition between the guide groove 17 and the main section 101, ensure the smoothness of the airflow, and reduce the driving wind resistance.

[0069] As a preferred implementation method, Figure 3 , Fig.11 and Fig.13 As shown in , the main body 401 is provided with a plurality of air intake pipes 18 corresponding to the main body section 101, and the air guide cover 3 is provided with a plurality of connecting pipes 301 corresponding to the connecting section 102, and each air intake pipe 18 is connected by plugging with the corresponding connecting pipe 301. It can be understood that by providing a plurality of air intake pipes 18 and a plurality of connecting pipes 301, and connecting the air intake pipes 18 and the connecting pipes 301 by plugging, the connection structure is simple, the operation is convenient, and it is conducive to ensuring the sealing of the connection position between the air intake pipe 18 and the connecting pipe 301.

[0070] When implementing it, Fig.13 and Fig.14As shown in the figure, the connecting pipe 301 has a first portion 3011 located at the front end and having a larger cross-sectional area, and a second portion 3012 located at the rear end and having a smaller cross-sectional area. When connected, the air intake pipe 18 is inserted into the first portion 3011 and abuts against the position where the first portion 3011 and the second portion 3012 are connected, thereby limiting the position of the air intake pipe 18, which is convenient for the subsequent connection of the connecting boss 5 and the connecting bracket 6.

By gradually reducing the cross-sectional area of ​​each air intake channel 1, it is beneficial to increase the air intake volume and reduce the driving wind resistance. And making the cross-sectional area of ​​the air outlet channel 2 a strip extending along a preset direction facilitates the smooth transition between the air intake channel 1 and the air outlet channel 2, thereby improving the smoothness of the air flow.

[0072] Of course, in the present embodiment, the cross-sectional area of ​​each air inlet channel 1 is gradually reduced, and the cross-sectional area of ​​the air outlet channel 2 is a long strip extending along a preset direction, just as a preferred implementation. In addition, in other embodiments, the structure of the air inlet channel 1 or the air outlet channel 2 can also be set to other forms, such as keeping the cross-sectional area of ​​the air inlet channel 1 unchanged, or setting the cross-sectional area of ​​the air outlet channel 2 to other shapes, such as a triangle, a trapezoid, etc.

[0073] The front-end air intake structure of the vehicle body of this embodiment is provided with a plurality of air intake channels 1 arranged in sequence along a preset direction on the structural body, and an air outlet channel 2 connected to the plurality of air intake channels 1, which is conducive to achieving a better flow guidance effect during vehicle driving and reducing the wind resistance of the vehicle.
