Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a fender structure and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, consumers are increasingly demanding lower fuel consumption and longer driving range. Reducing the drag coefficient can decrease fuel consumption or increase driving range. Therefore, major automakers are pursuing cars with low drag coefficients. Besides focusing on styling to create cars with lower drag, various aerodynamic accessories are increasingly being applied to automobiles. Among these technologies, aerodynamic accessories located at the fenders are often installed using a modular assembly method, which can easily lead to complex structures and, if loose, can affect airflow performance. Utility Model Content

[0003] This application provides a fender structure designed to improve the problem of complex aerodynamic accessories at the fender that easily affect airflow.

[0004] According to an embodiment of this application, the fender structure includes a first fender, which includes an inner fender and an outer fender. The outer fender is installed on the outside of the inner fender, and a portion of the outer surface of the inner fender is recessed inward to form an air guide groove that penetrates the inner fender in the front-rear direction. The outer fender covers the opening of the air guide groove to form an air guide channel.

[0005] According to the fender structure of the present application embodiment, the air guide channel is directly formed by assembling the inner fender and the outer fender, which makes the structure of the air guide channel more stable and less likely to cause problems such as loosening affecting the air guiding effect. In addition, the formation of the air guide channel of the present application does not require pneumatic accessories, which can reduce the number of parts, thereby helping to optimize the structural complexity of the fender structure, and thus also helping to reduce the assembly difficulty and improve the assembly effect.

[0006] In some embodiments of this application, the air guide channel includes an upper air guide surface and a lower air guide surface. In the direction from front to back, the upper air guide surface and / or the lower air guide surface are inclined in a direction away from each other, so that the air guide cross section of the air guide channel gradually increases in the direction from front to back.

[0007] In the above example, the increased cross-sectional area causes the airflow to diffuse within the channel, reducing flow velocity and pressure, decreasing eddy current generation, further optimizing aerodynamic performance, reducing vehicle drag, reducing energy consumption, and improving fuel economy or the driving range of electric vehicles; at the same time, stable and gentle airflow can significantly reduce wind noise and improve driving comfort.

[0008] In some embodiments of this application, the front end of the upper air guide surface is connected to a folded surface, and in the direction from back to front, the folded surface is inclined in a direction away from the lower air guide surface.

[0009] In the above example, by constructing a folded surface, the air inlet can be enlarged, thereby increasing the airflow into the air guide channel and helping to reduce wind resistance.

[0010] In some embodiments of this application, the air guide channel includes an inner air guide surface and an outer air guide surface. In the direction from front to back, the inner air guide surface and / or the outer air guide surface are inclined in a direction away from each other, so that the air guide cross section of the air guide channel gradually increases in the direction from front to back.

[0011] In the above example, the increased cross-sectional area causes the airflow to diffuse within the channel, reducing flow velocity and pressure, decreasing eddy current generation, further optimizing aerodynamic performance, reducing vehicle drag, reducing energy consumption, and improving fuel economy or the driving range of electric vehicles; at the same time, stable and gentle airflow can significantly reduce wind noise and improve driving comfort.

[0012] In some embodiments of this application, both the inner fender and the outer fender are integrally formed plastic fenders.

[0013] In the above examples, the one-piece molding process can improve the consistency between the inner and outer fenders, which is beneficial to improving the structural strength of the inner and outer fenders. The inner and outer fenders made of plastic materials can be designed according to actual needs in terms of shape and size, which is flexible, easy to process, and lightweight, which is beneficial to the lightweight design of vehicles.

[0014] In some embodiments of this application, the fender structure further includes a second fender connected to the vehicle body, the upper side of the inner fender being connected to the second fender, the side of the inner fender near the door being connected to a side panel bracket, and the inner fender and / or the outer fender having multiple mounting positions, each of which is suitable for mounting electrical components.

[0015] In the example above, the inner fender is connected to the second fender, which can improve the stability and structural strength of the inner fender. This results in good stability of the electrical components after they are assembled on the inner fender. The outer fender can better protect the electrical components and the inner fender. The layered design of the inner and outer fenders makes the installation division of labor clear, simplifies the operation process, and reduces the probability of errors.

[0016] In some embodiments of this application, the fender structure further includes a mounting bracket, at least one of which is provided and mounted at the mounting location, wherein the electrical components are adapted to be mounted on the plastic fender via the mounting bracket.

[0017] In the example above, if it is necessary to replace other models of electrical components, a mounting bracket can be added to install other models of electrical components on the plastic fender. This eliminates the need for complex modifications to the plastic fender and reduces design and production costs.

[0018] In some embodiments of this application, the second fender is a one-piece metal fender.

[0019] In the example above, the second fender is a metal fender, which can provide more robust support for the vehicle, improve structural stability and impact resistance, and ensure vehicle safety.

[0020] In some embodiments of this application, the inner fender has a U-shaped mating portion on the side near the door. The mating portion includes a bottom plate, a first side plate, and a second side plate. Along the thickness direction of the inner fender, the first side plate and the second side plate are respectively connected to both sides of the bottom plate. The outer side of the first side plate is coplanar with the outer side of the door outer panel, and the side of the second side plate away from the bottom plate extends toward the side bracket.

[0021] In the example above, the design of the outer side of the first side panel being coplanar with the outer side of the door panel achieves seamless connection between components, optimizes the vehicle's exterior lines, reduces wind resistance, and enhances the overall integrity and aesthetics of the vehicle body. The second side panel extends towards the side bracket, strengthening the connection between the inner fender and the side bracket, forming a stable support structure that can effectively disperse vibrations and external forces during vehicle operation, providing a stable operating environment for electrical components.

[0022] This application also proposes a vehicle having the fender structure described in the above embodiments.

[0023] According to the embodiments of this application, by providing the fender structure of the above embodiments, the vehicle can have all the beneficial effects brought by the fender structure, that is, while ensuring the structural strength of the vehicle, the aesthetics of the vehicle can be improved, and the vehicle can also be equipped with multiple electrical components, and the assembly of the electrical components is simple and convenient.

[0031] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] With the rapid development of the automotive industry, consumers are increasingly demanding lower fuel consumption and longer driving range. Reducing the drag coefficient can decrease fuel consumption or increase driving range. Therefore, major automakers are pursuing cars with low drag coefficients. Besides focusing on styling to create cars with lower drag, various aerodynamic accessories are increasingly being applied to automobiles. Among these technologies, aerodynamic accessories located at the fenders are often installed using a modular assembly method, which can easily lead to complex structures and, if loose, can affect airflow performance.

[0033] like Figures 1-5As shown in the embodiment of this application, a fender structure 100 includes a first fender 2, which includes an inner fender 21 and an outer fender 22. The outer fender 22 is installed on the outside of the inner fender 21. A portion of the outer surface of the inner fender 21 is recessed inward to form an air guide groove that penetrates the inner fender 21 in the front-rear direction. The outer fender 22 covers the opening of the air guide groove to form an air guide channel 3.

[0034] In other words, the outer fender 22 is installed on the outside of the inner fender 21, serving both aesthetic and protective functions. It can effectively resist the impact and scratches of sand and gravel, and protect the internal electrical components and the inner fender 21. A through air guide channel 3 is provided between the inner fender 21 and the outer fender 22. The air guide channel 3 can optimize the airflow path, reduce the generation of eddies and turbulence, reduce wind noise, and improve driving comfort. At the same time, reasonable airflow guidance can reduce vehicle wind resistance, reduce energy consumption, and improve fuel economy or driving range.

[0035] In addition, the air guide channel 3 is directly formed by assembling the inner fender 21 and the outer fender 22, which makes the structure of the air guide channel 3 more stable and less likely to cause problems such as loosening affecting the air guiding effect. Furthermore, the formation of the air guide channel 3 in this application does not require aerodynamic accessories, which can reduce the number of parts, thereby helping to optimize the structural complexity of the fender structure 100, and thus also helping to reduce the assembly difficulty and improve the assembly effect.

[0036] According to the fender structure 100 of this application embodiment, the air guide channel 3 is directly formed by assembling the inner fender 21 and the outer fender 22, which makes the structure of the air guide channel 3 more stable and less likely to cause problems such as loosening affecting the air guiding effect. In addition, the formation of the air guide channel 3 of this application does not require pneumatic accessories, which can reduce the number of parts, thereby helping to optimize the structural complexity of the fender structure 100, and thus also helping to reduce the assembly difficulty and improve the assembly effect.

[0037] In some embodiments of this application, the air guide channel 3 includes an upper air guide surface 61 and a lower air guide surface 62. In the direction from front to back, the upper air guide surface 61 and / or the lower air guide surface 62 are inclined in a direction away from each other, so that the air guide cross section of the air guide channel 3 gradually increases in the direction from front to back.

[0038] In the aforementioned technical methods, the increased cross-sectional area causes the airflow to diffuse within the channel, reducing flow velocity and pressure, decreasing eddy current generation, further optimizing aerodynamic performance, reducing vehicle wind resistance, reducing energy consumption, and improving fuel economy or the driving range of electric vehicles; at the same time, stable and gentle airflow can significantly reduce wind noise and improve driving comfort.

[0039] Further integration Figure 3As shown in the example, the air duct 3 has an air inlet at the front end and a rear air outlet at the rear end. In the vertical direction, the size of the air inlet is smaller than the size of the air outlet.

[0040] In some embodiments of this application, the front end of the upper air guide surface 61 is connected to a folded surface 60. In the direction from back to front, the folded surface 60 is inclined in a direction away from the lower air guide surface 62. Thus, by constructing the folded surface 60, the air inlet can be increased, thereby increasing the airflow into the air guide channel 3 and helping to reduce wind resistance.

[0041] In some embodiments of this application, the air guide channel 3 includes an inner air guide surface 63 and an outer air guide surface 64. In the direction from front to back, the inner air guide surface 63 and / or the outer air guide surface 64 are inclined in a direction away from each other, so that the air guide cross section of the air guide channel 3 gradually increases in the direction from front to back.

[0042] In the aforementioned technical methods, the increased cross-sectional area causes the airflow to diffuse within the channel, reducing flow velocity and pressure, decreasing eddy current generation, further optimizing aerodynamic performance, reducing vehicle wind resistance, reducing energy consumption, and improving fuel economy or the driving range of electric vehicles; at the same time, stable and gentle airflow can significantly reduce wind noise and improve driving comfort.

[0043] In some embodiments of this application, the inner fender 21 and the outer fender 22 are both integrally formed plastic fenders.

[0044] Among the above-mentioned technical methods, the one-piece molding process can improve the consistency between the inner fender 21 and the outer fender 22, which can help improve the structural strength of the inner fender 21 and the outer fender 22. The inner fender 21 and the outer fender 22 formed by plastic materials can be designed according to actual needs in terms of shape and size, which is flexible, easy to process, and lightweight, which can help the vehicle's lightweight design.

[0045] In some embodiments of this application, the fender structure 100 further includes a second fender 1 connected to the vehicle body, the upper side of the inner fender 21 connected to the second fender 1, the side of the inner fender 21 near the door connected to the side bracket 300, and the inner fender 21 and / or the outer fender 22 having multiple mounting positions, each of which is suitable for mounting electrical components.

[0046] In related technologies, with the rapid development of intelligent vehicles, most cars will install electronic components such as cameras, radars, and indicator lights in the fender area to enhance their competitiveness. For the installation of these electronic components, related technologies often employ the solution of adding plastic trim pieces; that is, the electronic components are fixed to the plastic trim pieces, which are then fixed to the fender. However, if a large number of electronic components are required, adding more plastic trim pieces can result in an excessive number of pieces, thus increasing assembly difficulty.

[0047] like Figures 1-5 As shown in the embodiment of this application, a fender structure 100 includes a first fender 2 and a second fender 1. The first fender 2 is connected to the second fender 1 and is installed on the outside of the second fender 1. The first fender 2 is provided with multiple mounting positions, each of which is suitable for installing electrical components.

[0048] For example, the second fender 1 can be a metal fender, providing robust support for the vehicle, improving structural stability and impact resistance, and ensuring vehicle safety. The first fender 2 can be a plastic fender, which is lightweight and easy to mold, reducing overall vehicle weight and energy consumption. Simultaneously, the first fender 2 has multiple mounting positions for electrical components, reducing the need for exterior trim parts, simplifying the assembly process, and lowering assembly difficulty and cost. During maintenance, the electrical components on the first fender 2 can be directly operated without disassembling numerous parts, shortening maintenance time, reducing maintenance costs, and improving the user experience.

[0049] The first fender 2 can be designed and processed into any shape as needed, allowing the vehicle to have any design at the fender, thus enhancing its aesthetics. Furthermore, because the first fender 2 is easy to form, it can be constructed with concave or convex structures suitable for the assembly of electrical components at the corresponding locations, facilitating the assembly and disassembly of these components. This provides high flexibility and practicality.

[0050] Furthermore, compared to the design scheme of multiple plastic decorative parts in related technologies, there are assembly gaps between multiple plastic decorative parts, and the positions of the plastic decorative parts also need to be determined to avoid interference. Therefore, there are many adverse factors affecting assembly efficiency and assembly effect during the assembly process. However, by designing the first fender 2, multiple electrical components can be assembled onto the first fender 2. The first fender 2 has no assembly gaps, and the assembly position of each electrical component is determined. This not only does not affect the assembly accuracy of multiple electrical components, but also improves the assembly accuracy of multiple electrical components to a certain extent. Moreover, multiple electrical components are less likely to interfere with each other, which can reduce assembly difficulty and improve assembly effect.

[0051] like Figures 1-5In the example shown, the first fender 2 includes an inner fender 21 and an outer fender 22. The inner fender 21 is connected to the second fender 1, and the outer fender 22 is installed on the outside of the inner fender 21. Multiple installation positions are located on the inner fender 21. The connection between the inner fender 21 and the second fender 1 provides good stability for the inner fender 21 and significantly improves its structural strength. Therefore, the inner fender 21, as a mounting carrier for electrical components, can provide reliable support for precision components such as cameras and radars using its stable structure, avoiding performance deviations caused by vibration. The outer fender 22, installed on the outside of the inner fender 21, serves both aesthetic and protective functions, effectively resisting impacts and scratches from sand and gravel, protecting the internal electrical components and the inner fender 21. During assembly, the layered structure clearly defines the division of labor in component installation, simplifies the operation process, and reduces the probability of errors. During maintenance, only the outer fender 22 needs to be removed to quickly access the electrical components on the inner fender 21, significantly shortening maintenance time. In addition, the layered design can optimize the use of materials. The outer fender 22 can be made of wear-resistant materials, while the inner fender 21 focuses on load-bearing performance, reducing costs while ensuring functionality.

[0052] like Figures 1-5 In the example shown, the upper side of the inner fender 21 is connected to the second fender 1, and the side of the inner fender 21 near the door is connected to the side bracket 300. This connection design forms a stable triangular support, which can disperse vibrations and external impacts during vehicle operation, providing a stable environment for electrical components installed on the inner fender 21 and ensuring the accurate operation of equipment such as cameras and radar. During assembly, the side bracket 300 can serve as a positioning reference, facilitating the rapid installation of the inner fender 21. Simultaneously, the stable connection enhances the overall structural strength, extending the service life of the inner fender 21, reducing later maintenance costs, and improving product reliability. In the example above, the assembly method ensures that the inner fender 21 is relatively stable after assembly, less prone to damage, extending its service life, and improving product reliability.

[0053] For example, mounting positions may also be formed on the outer fender 22, or clearance holes may be formed on the outer fender 22 to allow electrical devices mounted on the inner fender 21 to send or receive signals from the clearance holes, or the clearance holes may allow electrical devices mounted on the inner fender 21 to extend out from the clearance holes. This application does not limit this.

[0054] In the above-mentioned technical method, the inner fender 21 is connected to the second fender 1, which can improve the stability and structural strength of the inner fender 21, so that the electrical components are well stable after being assembled on the inner fender 21. The outer fender 22 can better protect the electrical components and the inner fender 21. The layered design of the inner fender 21 and the outer fender 22 makes the installation division clear, simplifies the operation process, and reduces the probability of errors.

[0055] In some embodiments of this application, the fender structure 100 further includes a mounting bracket 5, at least one of which is provided and mounted at a mounting position, and electrical components are adapted to be mounted on the first fender 2 via the mounting bracket 5.

[0056] In other words, the first fender 2 has sufficient assembly space. Taking one model of the vehicle's camera, radar, or other electronic components as an example, the first fender 2 can be directly configured with the assembly position for that model. However, in actual use, if the user wants to replace other models of cameras, radar, or other electronic components, the first fender 2 can be equipped with an assembly structure that cooperates with the mounting bracket 5. Thus, the number and position of the mounting bracket 5 can be flexibly adjusted according to the type and size of the electronic components, adapting to the installation needs of various cameras, radars, and other equipment, without requiring complex modifications to the first fender 2, reducing design and production costs. The mounting bracket 5 itself has a stable structure, providing reliable support for the electronic components, buffering vehicle vibrations, and preventing loose parts from affecting performance. During installation, the mounting bracket 5 simplifies assembly and improves assembly efficiency; during maintenance, disassembling the bracket allows separation of the electronic components without damaging the overall structure of the fender, shortening maintenance time, reducing maintenance difficulty, and enhancing product practicality.

[0057] In the above example, if it is necessary to replace other types of electrical components, the mounting bracket 5 can be added to install other types of electrical components on the first fender 2 without making complex modifications to the first fender 2, which can reduce design and production costs.

[0058] In some embodiments of this application, the second fender 1 is a one-piece metal fender.

[0059] In the above-mentioned technical method, the second fender 1 is a metal fender, which can provide a more solid support for the vehicle, improve structural stability and impact resistance, and ensure vehicle safety.

[0060] In some embodiments of this application, the inner fender 21 has a U-shaped mating part 4 on the side near the door. The mating part 4 includes a bottom plate 41, a first side plate 42, and a second side plate 43. Along the thickness direction of the inner fender 21, the first side plate 42 and the second side plate 43 are respectively connected to the two sides of the bottom plate 41. The outer side of the first side plate 42 is coplanar with the outer side of the door outer plate 200, and the side of the second side plate 43 away from the bottom plate 41 extends toward the side bracket 300.

[0061] In other words, the design of the outer side of the first side panel 42 being coplanar with the outer side of the door panel 200 achieves seamless connection between components, which can optimize the vehicle's exterior lines, reduce wind resistance, and improve the overall integrity and aesthetics of the vehicle body; the second side panel 43 extends towards the side bracket 300, which enhances the connection strength between the inner fender 21 and the side bracket 300, forming a stable support structure that can effectively disperse vibrations and external forces during vehicle operation, providing a stable operating environment for electrical components.

[0062] For example, the base plate 41, the first side plate 42 and the second side plate 43 in the U-shaped mating part 4 together form a regular space, which can also facilitate the orderly arrangement and fixation of components such as wire harnesses and pipes, reduce the risk of interference between components, and improve assembly efficiency and accuracy.

[0063] like Figures 1-5 As shown, in some embodiments of this application, the upper edge of the inner fender 21 is provided with a first snap-fit ​​portion 211, and the upper edge of the second fender 1 is provided with a second snap-fit ​​portion, and the first snap-fit ​​portion 211 and the second snap-fit ​​portion are snap-fit ​​connected.

[0064] In other words, compared to traditional bolt or welding methods, the snap-fit ​​connection is simpler and faster to operate, allowing for direct and quick component positioning and fixation, significantly improving production efficiency and reducing labor costs. The snap-fit ​​structure, through precisely designed snap-fit ​​buckles and slots, forms a tight engagement, effectively resisting vibration and external forces during vehicle operation, ensuring connection stability, and preventing component loosening from affecting electrical component operation. During maintenance, the snap-fit ​​design facilitates disassembly, allowing maintenance personnel to easily separate the inner fender 21 from the second fender 1 for quick inspection of internal electrical components, shortening maintenance time and reducing maintenance difficulty.

[0065] like Figures 1-5 As shown, in some embodiments of this application, the inner fender 21 is connected to the side bracket 300 by a snap fastener and / or bolt 212.

[0066] For example, the inner fender 21 and the side bracket 300 are connected by a snap-fit ​​connection. This snap-fit ​​connection method is simple and quick to operate, allowing for direct and rapid component positioning and fixation, significantly improving production efficiency and reducing labor costs. The snap-fit ​​structure, through the precise design of the snap-fit ​​and slots, forms a tight engagement, effectively resisting vibration and external forces during vehicle operation, ensuring connection stability, and preventing loosening of components from affecting the operation of electrical devices. During maintenance, the snap-fit ​​design facilitates disassembly, allowing maintenance personnel to easily separate the inner fender 21 from the side bracket 300 for quick inspection of internal electrical components, shortening maintenance time and reducing maintenance difficulty.

[0067] For example, the inner fender 21 and the side bracket 300 are connected by bolts 212. The bolt connection provides a high-strength and high-stability fastening effect, ensuring that the inner fender 21 and the side bracket 300 are firmly connected during vehicle operation.

[0068] In the above example, the assembly method of either snap-fit ​​or bolt 212 connection can be selected according to actual needs, which provides good flexibility.

[0069] like Figures 1-5 As shown, in some embodiments of this application, the inner fender 21 and the outer fender 22 are welded and / or connected by screws.

[0070] In other words, welding connects the inner fender 21 and the outer fender 22 into a single unit, providing high connection strength that effectively resists vehicle vibrations and external impacts, ensuring the safety of internal electrical components and extending component lifespan. Screw connections, on the other hand, are simple to operate, allowing for quick installation and significantly improving assembly efficiency. The combination of welding and screw connections between the inner fender 21 and the outer fender 22 meets strength requirements under different operating conditions while also ensuring installation flexibility. During maintenance, screws facilitate disassembly and inspection of damaged components, while welding ensures the core structure's stability, practicality, and high reliability.

[0071] In the above examples, welding or screw connection can be selected according to actual needs, which is practical and reliable.

[0072] like Figures 1-5 As shown, in some embodiments of this application, an air guide channel 3 is provided between the inner fender 21 and the outer fender 22, and the air guide channel 3 extends through the first fender 2 in the front-rear direction.

[0073] In other words, a through-flow air guide channel 3 is provided between the inner fender 21 and the outer fender 22. The air guide channel 3 can optimize the airflow path, reduce the generation of eddies and turbulence, reduce wind noise, and improve driving comfort. At the same time, reasonable airflow can reduce vehicle wind resistance, reduce energy consumption, and improve fuel economy or driving range.

[0074] For example, the cross-sectional area of ​​the air guide channel 3 gradually increases from front to back. The increased cross-sectional area causes the airflow to form a diffusion effect within the channel, reducing the flow velocity and pressure, reducing the generation of eddies, further optimizing aerodynamic performance, reducing vehicle wind resistance, reducing energy consumption, and improving fuel economy or the driving range of electric vehicles; at the same time, the stable and gentle airflow can significantly reduce wind noise and improve driving comfort.

[0075] Further integration Figure 2 As shown in the example, the air duct 3 has an air inlet at the front end and a rear air outlet at the rear end. In the vertical direction, the size of the air inlet is smaller than the size of the air outlet.

[0076] In addition, the operation of the electrical components generates heat, which can be conducted to the inner fender 21 and the outer fender 22. The continuous airflow in the air duct 3 can quickly remove the heat from the inner fender 21 and the outer fender 22, thus facilitating the heat dissipation of the electrical components in the heat dissipation path direction.

[0077] In the example above, by constructing the airflow channel 3, the airflow can be guided to reduce the vehicle's wind resistance, reduce energy consumption, and improve fuel economy or driving range.

[0078] The following is for reference. Figures 1-5 This application describes a specific embodiment of a fender structure 100.

[0079] This application provides a fender structure 100, which can accommodate various electrical components according to the overall vehicle and styling requirements. It also solves the problem of high dimensional accuracy requirements for electrical components, reduces peripheral fittings, improves aesthetics, and reduces assembly time. This fender structure 100 can also be configured as an integral first fender 2 (i.e., the first fender 2 is a single plate) or a split first fender 2 structure (i.e., a combination of inner fender 21 and outer fender 22) according to styling requirements.

[0080] like Figures 1-5The fender structure 100 shown in this application is a split-type fender structure 100 integrating a camera bracket, an indicator light mounting bracket 5, and an air duct 3. This fender structure 100 includes an outer fender 22, an inner fender 21, and a mounting bracket 5 (added according to the needs of different electrical component mounting, or omitted, i.e., directly mounted to the inner fender 21) to address the varying mounting requirements of electrical components in different configurations. The upper part of the fender structure 100 is fixed to the second fender 1 by clips, and the side near the door is fixed to the side panel bracket 300 by bolts 212, or alternatively, by clips. The fender structure 100 is mainly connected by the inner fender 21 and the second fender 1. The outer fender 22 is fixed to the inner fender 21 by welding and screws. At the air duct 3 required for aerodynamics, the inner fender 21 is recessed inward, thus forming an air duct 3 with the outer fender 22. At the junction of the inner fender 21 and the side bracket 300, the inner fender 21 is made into a U-shaped mating part 4. The first side plate 42 is fitted with the door, and the second side plate 43 is fitted with the side bracket 300 to cover the Y-direction cavity of the door and the side bracket 300, thereby improving the overall aesthetics of the vehicle.

[0081] Beneficial Effects: The fender structure 100 provided in this application includes an outer fender 22, an inner fender 21, and a mounting bracket 5 (used to address different configuration requirements). It can integrate indicator lights, cameras, air ducts 3, side decorative panels, and other structures. The indicator lights and cameras are first mounted on the first fender 2, and then the first fender 2 is fixed to the second fender 1. This fender structure 100 is simple in structure, easy to install, and can improve the relative dimensional tolerances between electrical components, while also enhancing the overall aesthetics and aerodynamic performance of the vehicle.

[0082] This application also proposes a vehicle having the fender structure 100 of the above embodiments.

[0083] According to the embodiments of this application, by providing the fender structure 100 of the above embodiments, the vehicle can have all the beneficial effects brought by the fender structure 100.
