[0002] In the field of vehicles, the aerodynamic performance of vehicles has an important influence on fuel economy, driving stability and engine cooling, etc. As an important component that can guide airflow and optimize the aerodynamic performance of vehicles, flow guide structure (such as flow guide cover) is widely used in modern automobile design.

[0003] At present, the flow guide cover arranged on the bumper is not reasonable in structure design, so that the airflow flowing into the flow guide cover is easy to flow into the engine compartment. This not only leads to poor wind guiding effect of the flow guide cover, but also cannot fully play the role of optimizing the aerodynamic performance, thereby being not conducive to reducing energy consumption. UTILITY MODEL CONTENT

[0004] Therefore, the utility model aims to provide a flow guide structure to improve the wind guiding effect.

[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] A flow guide structure comprises:

[0007] A front flow guide cover is arranged on the front bumper corresponding to the air inlet on the front bumper, and a first channel is formed on the front flow guide cover;

[0008] A rear flow guide cover, the air inlet end of the rear flow guide cover is sealingly connected to the air outlet end of the front flow guide cover, the air outlet end of the rear flow guide cover extends to the outside of the vehicle, and a second channel is formed on the rear flow guide cover;

[0009] A mounting bracket is arranged on the front bumper corresponding to the air outlet end of the rear flow guide cover, and the rear flow guide cover is fixed on the mounting bracket.

[0010] Further, the mounting bracket comprises a mounting plate arranged along the edge of the front bumper, and a boss protruding to the side of the rear flow guide cover; the rear flow guide cover is detachably arranged on the boss.

[0011] Further, the mounting plate has a first mounting table protruding to the side of the front bumper, and the mounting bracket is connected to the front bumper through the first mounting table; and / or, a limiting hole is arranged on the mounting plate, a limiting plate is arranged on the front bumper, the limiting plate is inserted into the limiting hole, and the displacement of the mounting bracket in the left-right direction of the vehicle is limited.

[0012] Further, the mounting bracket is provided with a rearward protruding flange plate on one side close to the front bumper edge, and the flange plate is connected with the fender.

[0013] Further, the rear fairing is provided with a sink groove around the second channel at the air inlet end, and the front fairing is inserted into the sink groove.

[0014] Further, the front end of the front fairing is provided with an annular flange protruding outward of the first channel, and a clamping portion is arranged between the annular flange and the front bumper, and the front fairing is clamped on the front bumper through the clamping portion.

[0015] Further, the front bumper is provided with a turned-up edge along the edge of the air inlet, and the turned-up edge is folded rearward, and the annular flange is provided with a groove around the first channel, and the turned-up edge is inserted into the groove.

[0016] Further, the annular flange is provided with a second mounting table protruding rearward, and the front end of the rear fairing is provided with an outwardly arranged lug, and the lug is connected with the second mounting table.

[0017] Further, the rear fairing is provided with a wire harness support for mounting a wire harness, and / or the cross sections of the first channel and the second channel gradually decrease in the direction away from the air inlet.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] The front bumper, the first channel and the second channel form a coherent and peripherally closed flow guiding path, so that the air guiding effect of the flow guiding structure is improved, the aerodynamic performance of the vehicle is improved, and the energy consumption of the vehicle is reduced.

[0020] Second, the mounting plate is arranged along the edge of the front bumper, providing a stable and fitted mounting base for the entire mounting bracket, and the structure of the mounting plate is simple, facilitating arrangement and implementation. The protruding design of the boss is used for mounting the rear fairing, which not only makes the mounting position of the rear fairing more accurate, but also effectively disperses the impact force from the airflow during vehicle driving, thereby reducing the shaking or displacement of the rear fairing due to uneven stress, thereby enhancing the stability of the entire fairing structure. Moreover, the rear fairing is detachably arranged on the boss, so when the rear fairing needs to be replaced due to damage, maintenance personnel can detach it from the boss without disassembling the entire fairing structure or the front bumper, which not only reduces the maintenance difficulty of the fairing structure and saves maintenance time, but also effectively reduces the maintenance cost of the vehicle.

[0021] Furthermore, by arranging the first mounting table protruding towards the front bumper side on the mounting plate, a larger contact area and support point can be provided for the connection between the mounting bracket and the front bumper, making the connection between the mounting bracket and the front bumper more stable and firm, and better dispersing the force generated during vehicle driving. The limiting hole on the mounting plate cooperates with the limiting plate on the front bumper to limit displacement and positioning, which helps to ensure that the mounting bracket does not deviate left and right during vehicle driving, thereby ensuring the installation accuracy of the fairing structure and keeping it in the best wind guiding position, and prolonging the service life of the fairing and the mounting bracket. The structure of the limiting plate and the limiting hole is simple, and the limiting effect of their cooperation is good.

[0022] In addition, the mounting bracket is provided with a rear protruding flange near the edge of the front bumper, which is connected to the fender, facilitating the installation of the fender and improving the structural utilization rate of the mounting bracket. The fixed frame is arranged to be connected to the fender, which also improves the installation effect of the fender and the structural utilization rate of the rear fairing. The rear end of the front fairing is inserted into the sink, making the fairing structure easy to position and operate during installation. The further arrangement of the sealing element helps to reduce air leakage at the connection, thereby improving the wind guiding effect of the fairing structure and reducing wind noise caused by air leakage, creating a quieter and more comfortable driving environment for the vehicle, thereby improving the comfort of the vehicle.

[0023] Furthermore, the annular flange design increases the contact area between the front fairing and the front bumper, thus improving the connection stability of the front fairing. The front bumper is engaged with the annular flange via a snap-fit ​​mechanism. Installers only need to align the annular flange with the corresponding position on the front bumper and engage it using the snap-fit ​​mechanism, eliminating the need for additional tools and significantly reducing installation time, thereby improving assembly efficiency. A rearward-folding flange is provided along the edge of the air intake on the front bumper, which cooperates with the groove on the annular flange surrounding the first channel to form a stable connection structure, further increasing the connection strength and stability between the front fairing and the front bumper.

[0024] The second mounting platform protruding rearward on the annular flange connects with the outwardly protruding lug at the front end of the rear fairing, facilitating a stable connection structure and increasing the contact area between the two, thus improving the stability of the connection. A wiring harness bracket is provided on the fairing for mounting the wiring harness, providing a fixed position and improving the installation stability and reliability of the wiring harness. As the cross-section of the channel decreases, the airflow velocity gradually increases, enabling more efficient guidance of the airflow in the predetermined direction and enhancing the airflow guiding effect of the airflow guiding structure.

[0025] In addition, another objective of this utility model is to provide a vehicle having the airflow guiding structure described above.

[0026] The vehicle described in this utility model, by setting the above-mentioned airflow guiding structure, helps to reduce wind resistance when the vehicle is driving, thereby improving fuel economy and reducing energy consumption. Attached Figure Description

[0052] Embodiment one

[0053] The embodiment relates to a flow guide structure, which is beneficial to improve the air guiding effect and reduce energy consumption.

[0054] The flow guide cover structure arranged on the bumper in the prior art is various, but due to unreasonable structure design, the airflow flowing into the flow guide cover is prone to flowing into the cabin, thereby affecting the air guiding effect of the flow guide cover and being not conducive to reducing the energy consumption of the vehicle.

[0055] To solve the above technical problems, the whole constitution of the air guide structure comprises a front fairing 2, a rear fairing 3 and a mounting bracket 4. The front fairing 2 is arranged on the front bumper 1 corresponding to the air inlet 101 on the front bumper 1, and a first channel 201 is formed on the front fairing 2. The air inlet end of the rear fairing 3 is sealingly connected with the air outlet end of the front fairing 2, the air outlet end of the rear fairing 3 extends to the outside of the vehicle, and a second channel 301 is formed on the rear fairing 3. The mounting bracket 4 is arranged on the front bumper 1 corresponding to the air outlet end of the rear fairing 3, and the rear fairing 3 is fixed on the mounting bracket 4.

[0056] The air guide structure of the embodiment forms a continuous and peripherally closed air guide path for the air inlet 101, the first channel 201 and the second channel 301 on the front bumper 1 by sealingly connecting the air inlet end of the rear fairing 3 with the air outlet end of the front fairing 2, thereby facilitating to improve the air guide effect of the air guide structure and the aerodynamic performance of the vehicle, and further facilitating to reduce the energy consumption of the vehicle.

[0057] Based on the above overall introduction, an exemplary structure of the air guide structure and the front bumper 1 in use is shown in Figures 1 to 4 , an exemplary structure of the air guide structure is shown in Figure 5 and Figure 6 . Considering that the air guide structure in the embodiment is preferably symmetrically arranged at the left and right ends of the front bumper 1, only the air guide structure at one end of the front bumper 1 is shown in the drawings for facilitating the description of the air guide structure.

[0058] The air inlet 101 in the embodiment is specifically located at the left end of the windward surface of the front bumper 1, and the air inlet 101 in the embodiment can be in the shape of an inverted water droplet as shown in Figure 1 and Figure 7 . The air inlet 101 is inclined outward along the direction from top to bottom, and the width of the air inlet 101 is gradually reduced along the direction from top to bottom. Of course, the shape and arrangement of the air inlet 101 can be adaptively adjusted according to the use requirements.

[0059] As shown in Figure 2 , the left and right ends of the front bumper 1 are each provided with a side portion extending rearward along the front-rear direction of the vehicle, and the air guide structure is specifically arranged on the side portion and extends along the front-rear direction of the vehicle. The air inlet end of the front fairing 2 is used to connect with the air inlet 101. As shown in Figure 2 and Figure 8 , the shape of the air inlet end of the front fairing 2 is adapted to the shape of the air inlet 101, so as to facilitate the connection effect of the two. As preferred, as shown in Figure 1As shown, when viewed from the front bumper 1, part of the inner wall of the front fairing 2 is exposed and matches the shape of the air intake 101, enhancing the sense of refinement in appearance.

[0060] In this embodiment, the front fairing 2 can be integrally injection molded to improve processing efficiency and facilitate vehicle weight reduction. As a preferred embodiment, the cross-section of the first channel 201 gradually decreases along the direction away from the air inlet 101. This allows the airflow velocity to gradually increase, enabling more efficient guidance of the airflow to the predetermined direction, thereby enhancing the airflow guiding effect of the front fairing 2. Furthermore, it allows the airflow to form a more stable airflow layer on the vehicle surface, reducing wind resistance in the airflow guiding structure, thereby further improving vehicle driving stability and fuel economy.

[0061] In addition, the front end of the front fairing 2 is provided with an annular flange 202 protruding outward from the first channel 201. A snap-fit ​​part is provided between the annular flange 202 and the front bumper 1, which snaps the front fairing 2 onto the front bumper 1. Here, the design of the annular flange 202 on the front fairing 2 helps to increase the contact area between the front fairing 2 and the front bumper 1, making the force distribution more even. By snapping it onto the front bumper 1 through the snap-fit ​​part, the installer only needs to align the annular flange 202 with the corresponding position on the front bumper 1, and use the elastic deformation of the snap-fit ​​part to achieve quick snap-fit ​​without the need for additional tools, which greatly shortens the installation time and thus improves assembly efficiency.

[0062] In terms of specific structure, such as Figures 7 to 9 As shown, the shape of the annular flange 202 is adapted to the shape of the corresponding front bumper 1 to improve the fit between the annular flange 202 and the front bumper 1. To improve the connection between the front bumper 1 and the front fairing 2, in this embodiment, the front bumper 1 is provided with a flange 103 along the edge of the air intake 101, and the flange 103 is folded backward. The annular flange 202 is provided with a groove 2021 surrounding the first channel, and the flange 103 is inserted into the groove 2021. Here, the groove 2021 is located on the inner edge of the annular flange 202, and the shape of the groove 2021 is adapted to the flange 103 to improve the insertion effect between the two. In this embodiment, the insertion of the flange 103 into the groove 2021 facilitates the formation of a nested connection structure, which further increases the connection stability between the front fairing 2 and the front bumper 1.

[0063] Further, after the flange 103 is inserted into the groove 2021, it can block part of the dust, rain and sundries from entering the connection between the two, thereby helping to reduce the erosion and damage of impurities to the components inside the flow guide structure and the engine compartment. At the same time, it also helps to prevent air leakage from the connection between the front bumper 1 and the front flow cover 2, thereby helping to further optimize the flow guide effect. Moreover, from the appearance of the vehicle, the design of the flange 103 inserted into the groove 2021 also makes the connection between the front flow cover 2 and the front bumper 1 smoother and more natural, thereby helping to reduce the obvious gap and jarring feeling at the connection between the front flow cover 2 and the front bumper 1, thereby helping to improve the appearance quality and delicate feeling of the whole vehicle.

[0064] As an exemplary structure of the clamping part, as shown in Figures 7 to 9 , the clamping part in the embodiment includes a plurality of clamping heads 1031 arranged on the flange 103 in a circumferential direction, and a plurality of clamping holes 2023 arranged on the groove bottom of the groove 2021 and corresponding to the clamping heads 1031. In specific implementation, the number and specific positions of the clamping heads 1031 and the clamping holes 2023 can be determined according to the use requirements. In the front-rear direction of the whole vehicle, the front flow cover 2 can be fixed on the front bumper 1 by clamping the clamping heads 1031 into the corresponding clamping holes 2023.

[0065] To further guide the front flow cover 2 during installation, two positioning pieces 1032 can be arranged on the left and right sides of the flange 103, and two first positioning holes 2024 corresponding to the positioning pieces 1032 can be arranged on the groove bottom of the groove 2021. During the clamping of the clamping heads 1031 and the clamping holes 2023, the insertion of the positioning pieces 1032 into the corresponding first positioning holes 2024 helps to improve the clamping efficiency of the front flow cover 2 on the front bumper 1. In addition, the insertion and fitting of the positioning pieces 1032 and the first positioning holes 2024 here also helps to further limit the movement of the front flow cover 2 in the up-down direction and the left-right direction of the whole vehicle, and cooperate with the clamping part, thereby helping to ensure the connection firmness and reliability between the front end of the front flow cover 2 and the front bumper 1.

[0066] An exemplary structure of the rear flow cover 3 in the embodiment is shown in Figure 5 , Figure 10 and Figure 11As shown, the rear fairing 3 can be integrally injection molded to improve processing efficiency and facilitate vehicle weight reduction. The outer periphery of the rear fairing 3 is closed, preventing airflow from flowing into the engine compartment through the outer periphery of the rear fairing 3 and causing air leakage. In this embodiment, the cross-section of the second channel 301 gradually decreases along the direction away from the air inlet 101. This arrangement gradually increases the airflow velocity, enabling more efficient guidance of the airflow to the predetermined direction, thereby enhancing the airflow guiding effect of the rear fairing 3. In this embodiment, the air outlet of the front fairing 2 is a long strip extending along the vertical direction of the vehicle, and the air inlet of the rear fairing 3 is also a long strip to improve the compatibility of the connection between the front fairing 2 and the rear fairing 3.

[0067] As a feasible implementation, the rear fairing 3 in this embodiment is flat to minimize its impact on the vehicle's interior space while achieving good airflow guidance. Furthermore, protrusions 307 are provided on both the inner and outer sides of the rear fairing 3. This improves the structural strength of the rear fairing 3, and the protrusions 307 have a simple structure, facilitating processing and molding. The protrusions 307 also help prevent deformation of the rear fairing 3 during injection molding or under high wind speeds. Of course, it is also feasible to provide a protrusion 307 only on one side of the rear fairing 3, or to provide other reinforcing structures on the rear fairing 3.

[0068] To improve the sealing effect at the connection between the front guide shield 2 and the rear guide shield 3, as a preferred embodiment, in this embodiment, the air inlet end of the rear guide shield 3 is provided with a recess 302 arranged around the second channel 301, the rear end of the front guide shield 2 is inserted into the recess 302, and a sealing member 5 is provided in the recess 302 sandwiched between the front guide shield 2 and the rear guide shield 3.

[0069] In this embodiment, the rear end of the front fairing 2 is inserted into the recess 302, making the airflow guiding structure easy to position and operate during installation. By further setting the sealing element 5, it is beneficial to reduce airflow leakage, effectively improve the air guiding effect, and reduce wind noise caused by airflow passing through the gap, creating a quieter and more comfortable driving environment in the vehicle, thereby improving comfort.

[0070] In terms of specific structure, such as Figure 11 As shown, to facilitate the connection between the rear fairing 3 and the front fairing 2, the front end of the rear fairing 3 has an outwardly inclined guide surface. Due to the guide surface, the front end of the rear fairing 3 is flared outwards in a trumpet shape. The guide surface guides the rear end of the front fairing 2, facilitating the insertion of the front end of the rear fairing 3 into the recess 302. Figure 12As shown in the middle, the sealing member 5 can be used specifically sealing sponge, the sealing member 5 is specifically sandwiched between the inner wall of the sink 302 and the outer wall of the front fairing 2 rear end. Not only easy to arrange the implementation, and good sealing effect, conducive to preventing the flow in the flow guide structure via the front fairing 2 and the rear fairing 3 connection out.

[0071] In order to facilitate the installation of the rear fairing 3, in the embodiment, as shown in Figure 5 and Figure 8 , the annular flange 202 is provided with a second mounting table 2022 protruding rearward, and the front end of the rear fairing 3 is provided with an outwardly arranged lug connected with the second mounting table 2022. In order to distinguish from the lug of the wire harness, the lug connected with the second mounting table 2022 is called front lug 303. In the embodiment, the lug is connected with the second mounting table 2022, which is conducive to forming a stable connection structure and increasing the contact area between the two, so that the connection part can withstand greater external force and has better use stability.

[0072] In detail, the front lug 303 is arranged at the top and bottom of the rear fairing 3 respectively, and the second mounting table 2022 is arranged on the annular flange 202 corresponding to the two front lugs 303. The front lug 303 here is preferably "Z" shaped as shown in Figure 10 , which not only facilitates lapping on the second mounting table 2022, but also improves the connection strength between the second mounting table 2022 and the front lug 303, and has high structural strength. In particular, a front connecting hole 3031 can be arranged on each front lug 303, and a reed nut 6 is arranged on the second mounting table 2022. The bolt is screwed with the corresponding reed nut 6 after passing through the front connecting hole 3031, so as to connect the front end of the rear fairing 3 with the front fairing 2 and fix the front end of the rear fairing 3.

[0073] The mounting bracket 4 in the embodiment can fix the rear end of the rear fairing 3 on the front bumper 1. As a preferred embodiment, as shown in Figures 2 to 4 , the mounting bracket 4 includes a mounting plate 401 arranged along the edge of the front bumper 1, and a boss 402 protruding to one side of the rear fairing 3, and the rear fairing 3 is detachably arranged on the boss 402. Here, the mounting plate 401 is arranged along the edge of the front bumper 1, which provides a stable and fitted mounting basis for the entire mounting bracket 4, and the structure of the mounting plate 401 is simple, which is easy to arrange and implement. The protruding design of the boss 402 is used to install the rear fairing 3, which not only makes the installation position of the rear fairing 3 more accurate, but also effectively disperses the impact force from the airflow during vehicle driving, reduces the shaking or displacement of the rear fairing 3 due to uneven force, and enhances the stability of the entire flow guide structure.

[0074] In addition, the rear fairing 3 is detachably arranged on the boss 402, when the fairing needs to be replaced due to damage, the maintenance personnel can easily detach it from the boss 402 without disassembling the entire fairing structure or the front bumper 1, which not only helps to reduce the maintenance difficulty and save the maintenance time, but also effectively reduces the damage to other parts of the vehicle caused by frequent disassembly, thereby helping to reduce the maintenance cost of the vehicle.

[0075] Based on the above overall introduction of the mounting bracket 4, an exemplary structure of the mounting bracket 4 in the embodiment is shown in Figure 13 and Figure 14 The top and bottom of the rear end of the rear fairing 3 are respectively provided with rear ears 306 arranged outward, and the boss 402 is arranged on the mounting plate 401 corresponding to the rear ears 306. The rear ears 306 are provided with rear connecting holes 3062, and the boss 402 is provided with spring nut 6 corresponding to the rear connecting holes 3062, and the bolt is screwed through the rear connecting holes 3062 and the corresponding spring nut 6, that is, the installation of the rear fairing 3 on the boss 402 is realized.

[0076] In order to further improve the installation convenience of the rear fairing 3, a positioning column 4021 can be arranged on each boss 402, and a second positioning hole 3061 corresponding to the positioning column 4021 is arranged on the rear ear 306. By inserting the positioning column 4021 into the second positioning hole 3061, the rear end of the rear fairing 3 is positioned on the mounting bracket 4, so that the rear connecting hole 3062 and the corresponding spring nut 6 are aligned, thereby improving the installation efficiency of the rear fairing 3.

[0077] The positioning column 4021 here can be a cross-section in the form of a "cross", which has high strength and rigidity and is not easy to deform when subjected to external force, and can provide reliable support for the matched parts. Of course, the structure of the positioning column 4021 can also be adjusted according to the use requirements. The gap between the positioning column 4021 and the second positioning hole 3061 in the embodiment is preferably 0.15mm-0.25mm, for example, the gap between the two can be 0.15mm, 0.18mm, 0.2mm, 0.22mm, 0.24mm or 0.25mm, which can be determined according to the requirements during specific implementation.

[0078] The rear fairing 3 in the embodiment can be firmly fixed by the cooperation of the front ear 303 and the rear ear 306, while also helping to ensure the assembly gap and the cooperation of the rear fairing 3, the front bumper 1 and the front fairing 2, thereby helping to ensure the installation strength and use stability of the fairing structure.

[0079] In order to facilitate the installation of the mounting bracket 4 on the front bumper 1, in the embodiment, the mounting plate 401 has a first mounting table 403 protruding towards the side of the front bumper 1, and the mounting bracket 4 is connected to the front bumper 1 through the first mounting table 403. Among them, the first mounting table 403 provides a larger contact area and support point for the connection between the mounting bracket 4 and the front bumper 1, and can better disperse various stresses generated during vehicle driving, making the connection between the mounting bracket 4 and the front bumper 1 more firm and stable.

[0080] As shown in detail in Figure 13 and Figure 14 , the first mounting table 403 is spaced apart along the length direction of the mounting plate 401, and each first mounting table 403 can be rectangular as shown in the figure, or other geometric shapes. In addition to the four shown in the figure, the first mounting table 403 can also be adaptively increased or decreased according to the use requirements. When connected, the first mounting table 403 is connected to the front bumper 1 by laser piercing welding, which has the characteristics of energy concentration and small heat-affected zone. This makes the welding process have little effect on the surrounding material performance, ensuring the original mechanical properties of the front bumper 1 and the mounting plate 401. At the same time, laser piercing welding can achieve high-precision welding, with high weld quality and high connection strength. Compared with traditional welding methods, it can further enhance the stability of the connection between the mounting bracket 4 and the front bumper 1.
