TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle accessories, and in particular to a fender structure and a vehicle. BACKGROUND

[0002] When the vehicle is running, the rotation of the wheel will compress the air in the wheel cavity, and the gas pressure will increase. The pressure relief port on the fender can discharge the high-pressure gas in the wheel cavity to maintain the balance of the air pressure in the wheel cavity, thereby reducing the impact of high-pressure gas on vehicle running.

In this way, not only the aerodynamic resistance is increased, affecting the aerodynamic efficiency, but also a hydraulic mechanism needs to be set to ensure that the cover plate is in an open state, and the structure is relatively complex.

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0031] The present application provides a fender structure, Figure 1 and Figure 2 a structural schematic view of the fender structure provided in the embodiments of the present application. Figures 3 to 5 a structural schematic view of a vehicle provided in the embodiments of the present application.

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 (for a clearer description of the scheme, Figure 1 and Figure 4The fender structure 100 includes the fender body 1 and the cover plate 2, the fender body 1 is provided with an opening 11 for pressure relief of the wheel cavity 300; the cover plate 2 is movably mounted on the fender body 1 and can move along the plane where part of the surface of the fender body 1 is located to cover the opening 11 (see Figure 5 ) or expose at least part of the opening 11 (see Figure 1 、 Figure 3 and Figure 4 ).

[0033] In the technical solution of the present application, the cover plate 2 moves along the plane where part of the surface of the fender body 1 is located, and when the cover plate 2 exposes at least part of the opening 11 to realize the pressure relief function, the cover plate 2 will not be raised towards the outside of the fender body 1, avoiding the aerodynamic resistance caused by the direct blowing of the airflow. During the driving of the vehicle 1000, this helps the airflow around the vehicle 1000 to flow more smoothly, reducing the energy loss caused by aerodynamic resistance, thereby improving the aerodynamic efficiency. Since the cover plate 2 will not be directly blown by the airflow, it is no longer necessary to use an additional hydraulic mechanism to maintain its open state, which reduces the number of components in the structure, avoids the problems of complex pipe connections, sealing and maintenance caused by the hydraulic mechanism, and makes the entire fender structure 100 more simple and compact. That is, in the technical solution of the present application, by moving the cover plate 2 along the plane where part of the surface of the fender body 1 is located, when the cover plate 2 exposes at least part of the opening 11 for pressure relief of the wheel cavity 300, the cover plate 2 will not be raised towards the outside of the fender body 1, avoiding the direct blowing of the airflow on the cover plate 2, and without additional aerodynamic resistance when the pressure in the wheel cavity 300 is relieved, improving the aerodynamic efficiency and facilitating structural simplification.

[0034] It can be understood that when the cover plate 2 moves along the plane where part of the surface of the fender body 1 is located and exposes at least part of the opening 11, the orthographic projection of the cover plate 2 on the fender body 1 is offset from the part of the opening 11 exposed, and the high-pressure gas smoothly passes through the exposed part of the opening 11, realizing efficient pressure relief of the wheel cavity 300.

[0035] The application does not limit the implementation mode that the cover plate 2 is movably mounted on the fender body 1 and the cover plate 2 can move along the plane where the partial surface of the fender body 1 is located. In some examples, a flexible hinge structure can be used between the cover plate 2 and the fender body 1. The flexible hinge structure is similar to a bendable connecting component, which allows the cover plate 2 to move within a certain range along the plane where the partial surface of the fender body 1 is located. When it is necessary to open the opening 11 to release pressure, the cover plate 2 can move within a limited range under the action of the flexible hinge, and will not be tilted outwardly to the outside of the fender body 1. In other examples, an elastic deformation connecting piece is used between the cover plate 2 and the fender body 1. The elastic deformation connecting piece allows the cover plate 2 to move along the plane where the partial surface of the fender body 1 is located, to expose or cover the opening 11. This connecting mode can also ensure that the cover plate 2 will not be tilted outwardly to the outside of the fender body 1, thereby avoiding the aerodynamic resistance caused by the direct airflow.

[0036] In some embodiments, the cover plate 2 is slidably connected or rotatably connected with the fender body 1. In these embodiments, the cover plate 2 is slidably connected or rotatably connected with the fender body 1. The sliding connection is usually composed of simple components, such as a sliding block and a guide rail, which are easy to design and manufacture. The sliding connection can provide higher movement accuracy for the cover plate 2 and has better stability during movement, and is not prone to vibration and shaking. The rotary connection can realize the rotation or swing of the cover plate 2 in the plane where the partial surface of the fender body 1 is located, has higher reliability, and is not prone to failure. The structure of the rotary connection is relatively simple, and maintenance and repair are relatively convenient. Through the sliding connection or rotary connection of the cover plate 2 with the fender body 1, the cover plate 2 is movably mounted on the fender body 1, and the cover plate 2 can move along the plane where the partial surface of the fender body 1 is located. The structure is simple and reliable, and maintenance is convenient.

[0037] It can be understood that the fender body 1 is located above the wheels 200 of the vehicle 1000, and its shape and position will vary depending on the vehicle model, but generally has a certain curvature to match the body lines. The cover plate 2 moves along the plane where the partial surface of the fender body 1 is located, which means that the movement of the cover plate 2 is limited in the plane determined by the partial surface of the fender body 1. The cover plate 2 will not deviate from this specific plane, neither tilted nor shifted in other directions. This limitation does not strictly mean that the partial structure of the cover plate 2 and the fender body 1 must completely coincide, but also covers a case where the cover plate 2 is mounted on the fender body 1, whether on the inner side 12 or the outer side of the fender body 1, and the two can closely cooperate with each other. Specifically, there will be no condition of too large gap or misalignment between the two, the shape of the cover plate 2 is matched with the fender body 1, so as to ensure that the cover plate 2 always maintains a close fit with the fender body 1, and then can move in the plane determined by the partial surface of the fender body 1.

[0038] In some embodiments, seeFigure 1 In some embodiments, the fender body 1 has an inner side 12 facing the wheel cavity 300, and the cover plate 2 is slidingly or rotatably connected to the inner side 12. In these embodiments, when the cover plate 2 is slidingly or rotatably connected to the inner side 12 of the fender body 1 facing the wheel cavity 300, it can be well hidden in the internal structure, and from the appearance of the vehicle 1000, this arrangement can maintain the simplicity of the external lines of the vehicle 1000 and will not destroy the overall aesthetic appearance due to the presence of the cover plate 2. Since the inner side 12 is relatively less disturbed by the outside world, the sliding or rotational connection between the cover plate 2 and the fender body 1 can better maintain stability, reduce the possibility of connection loosening or damage caused by external collision and other factors, and improve structural stability.

[0039] In some embodiments, see Figure 1 The inner side 12 of the fender structure 100 is provided with a sliding rail 3, and the cover plate 2 is slidingly arranged in the sliding rail 3. In these embodiments, since the sliding rail 3 plays a guiding role in the movement of the cover plate 2, the cover plate 2 can only slide in the direction of the sliding rail 3, which ensures that the movement of the cover plate 2 in the inner side 12 of the fender structure 100 has very high directional accuracy and will not deviate from the preset path. The cover plate 2 can accurately reach the designated position. During the manufacturing process of the vehicle 1000, it is relatively simple to install the cover plate 2 in the inner side 12 of the fender structure 100 through the sliding rail 3, which reduces the installation difficulty and time cost, is easy to maintain, and improves the maintenance efficiency.

[0040] The sliding direction of the cover plate 2 is not limited in this application, for example, the cover plate 2 can slide substantially in the transverse direction of the vehicle 1000.

[0041] In some embodiments, the fender structure 100 has a front end 13 facing the front of the vehicle and a rear end 14 facing the rear of the vehicle, and the cover plate 2 can slide between the front end 13 and the rear end 14. In these embodiments, the cover plate 2 can slide between the front end 13 and the rear end 14, avoiding transverse space interference, and will not interfere with other transversely arranged components (such as brake pipelines, suspension components, etc.) inside the wheel cavity 300, ensuring the rationality of the space layout inside the wheel cavity 300, so that each component can be installed compactly and without interference, and the space utilization and component layout are more reasonable.

[0042] In some embodiments, see Figure 1 and Figure 2 The cover plate 2 slides towards the front end 13 from the rear end 14 to expose at least part of the opening 11, and the cover plate 2 includes a plate body 21 and a protruding portion 22 connected to one end of the plate body 21 facing the rear end 14 and protruding away from the inner side 12. In these embodiments, the protruding portion 22 protrudes away from the inner side 12, which can guide the direct airflow and reduce the impact of the airflow on the pressure relief airflow Figure 2 and Figure 3The impact (indicated by three arc-shaped arrows) makes the airflow exchange at the opening 11 smoother, enhances the aerodynamic efficiency of the pressure relief port, and achieves the pressure relief function more efficiently. In addition, the protrusion 22 can act as a handle, providing users with a convenient operating part. When it is necessary to slide the cover 2 to expose the opening 11, the user can easily grasp the protrusion 22 and apply a pulling force to make the cover 2 slide from the rear end 14 towards the front end 13, making the operation more intuitive and convenient.

[0043] In some embodiments, see Figure 1 The angle between the protrusion 22 and the plate body 21 is between 80° and 100°. When the angle is between 80° and 100°, the protrusion 22 can guide the airflow at a suitable angle. This angle range ensures that when facing a direct airflow, the protrusion 22 will not cause the airflow to turn too sharply due to an angle that is too small (which may lead to turbulence), nor will it fail to effectively change the airflow direction due to an angle that is too large. For example, an angle close to 90° can cause the airflow to turn more smoothly when passing over the protrusion 22, which is beneficial for guiding the airflow to the expected direction, enhancing the guiding effect on the direct airflow, and thus improving the aerodynamic efficiency of the pressure relief port. When the protrusion 22 is used as a handle, the angle of 80° to 100° makes it comfortable for the user to hold the protrusion 22 and pull the cover plate 2. It matches the natural grip posture of the human hand, does not require excessive wrist twisting, and makes it convenient for the user to apply pulling force to slide the cover plate 2.

[0044] In some embodiments, see Figure 1 In the directions of the end of the protrusion 22 facing away from the plate body 21 and the end of the protrusion 22 connected to the plate body 21, the size of the protrusion 22 is between 10mm and 20mm. In these embodiments, when the size of the protrusion 22 is between 10mm and 20mm, it can have a moderate influence on the airflow. This size range is neither too small to effectively change the direction of the direct airflow and fail to guide the direct airflow, nor too large to cause excessive aerodynamic drag and affect aerodynamic efficiency. In addition, the size range of 10mm to 20mm is suitable for the protrusion 22 to be used as a handle. This range is sufficient for the user to grip the protrusion 22 to slide the cover 2. Moreover, this size is not too large, otherwise the entire structure of the cover 2 will appear uncoordinated and have an adverse effect on the overall appearance of the vehicle.

[0045] In some embodiments, the fender structure 100 further comprises a driving device (not shown in the figure) in driving connection with the cover plate 2. In these embodiments, the addition of the driving device realizes the automation of the sliding of the cover plate 2, and the user only needs to control the sliding of the cover plate 2 through the control button or other control mode in the vehicle, greatly improving the convenience of operation, especially in some special situations, such as the need to adjust the position of the cover plate 2 during the driving of the vehicle 1000, the automatic operation is safer and more convenient. The driving device can accurately control the moving position and speed of the cover plate 2, ensuring that the cover plate 2 can be accurately moved to the specified position, realizing the accurate exposure or shielding of the opening 11, and meeting the needs of pressure relief under different working conditions. The driving device can provide stable power output, making the cover plate 2 more stable during sliding, reducing the shaking or jamming of the cover plate 2 caused by improper manual operation, and improving the running stability of the entire fender structure 100. In some examples, the driving device includes a motor, which drives the transmission device (such as gears, belts, etc.) to move, thereby driving the cover plate 2 to move as needed.
