[0062] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0063] Next, we will refer to Figures 1-9 The fender assembly 100 of some embodiments of the present invention will be described, and the direction indicated by the arrows in the figures is the direction of airflow.

[0064] It should be noted that, in a specific example, in Figures 1-9 In the diagram, the X direction represents the length of the vehicle; the Y direction represents the width of the vehicle; and the Z direction represents the height of the vehicle.

[0065] refer to Figures 1-2 An embodiment of the first aspect of this utility model provides a fender assembly 100 for use in a vehicle. The fender assembly 100 includes a fender body 1 and an air guide structure 2. The air guide structure 2 is disposed on the outside of the fender body 1, and the air guide structure 2 and the fender body 1 define an air guide channel 3.

[0066] Among them, the outer side of the fender body 1 is the side of the fender body 1 away from the vehicle body; correspondingly, the inner side of the fender body 1 is the side of the fender body 1 facing the vehicle body.

[0067] The air guide structure 2 is located on the outer side of the fender body 1, thus exposing it to the outside of the vehicle. This facilitates installation of the air guide structure from the outside of the fender body 1, reducing the difficulty of installation. Furthermore, it reduces the constraints imposed by the internal structures of the fender body 1 on the structural design of the air guide structure, thereby increasing the flexibility of the air guide structure 2 and the air guide channel 3. The structural design of the air guide structure 2 can be adjusted more flexibly to optimize its airflow effect on the vehicle. For example, the airflow area of ​​the air inlet 31 of the air guide channel 3 can be increased by enlarging the size of the air guide structure 2, further improving the airflow effect of the air guide channel and reducing air resistance.

[0068] By placing the air guide structure 2 on the outside of the fender body 1, and thus the air guide channel 3 is located on the outside of the fender body 1, when the fender assembly 100 is used in a vehicle, the obstruction of the airflow through the air guide channel 3 by other components connected to the fender assembly 100 is minimized. This reduces the structural design requirements of these components on the fender assembly 100, thereby reducing the complexity of their structural design and the difficulty of their molding. For example, during the design and molding process of the door, the air outlet 32 ​​of the air guide channel 3 is exposed on the outside of the door, eliminating the need for a significant inward concavity design relative to the fender body 1, thus reducing the complexity of the door's structural design and the difficulty of its molding.

[0069] For example, the air inlet 31 of the air guide channel 3 faces the vehicle's wheels. During the vehicle's operation, the airflow from the front of the vehicle enters through the air inlet 31 of the air guide channel 3, flows through the air guide channel 3, and then flows towards the rear of the vehicle through the air outlet 32 ​​of the air guide channel 3. The arrangement of the air guide structure 2 helps to optimize the airflow path, which can reduce turbulence around the wheels, thereby reducing air resistance and improving fuel efficiency or driving range.

[0070] For example, the fender assembly 100 is used in a vehicle. The air duct 3 extends in the front-rear direction. The front and rear ends of the air duct 3 are respectively provided with an air inlet 31 and an air outlet 32. The wheel fender is located on the front side of the fender assembly 100 and is provided with a vent that communicates with the air inlet 31. The door is located on the rear side of the air duct component and defines a gap between it and the fender assembly 100 that communicates with the air outlet 32. This gap forms an exhaust vent. That is, the vent is connected to the air duct 3 through the air inlet 31, and the air duct 3 is connected to the exhaust vent through the air outlet 32. This forms a connected airflow channel between the vent, the air inlet 31, the air duct 3, the air outlet 32, and the exhaust vent. This allows the airflow on the front side of the fender to flow sequentially through the vent, the air inlet 31, the air duct 3, the air outlet 32, and the exhaust vent to the rear side of the fender assembly 100, thereby effectively reducing air resistance at the fender and improving the aerodynamic performance of the vehicle.

[0071] Optionally, the fender assembly 100 can be a one-piece molded part or a separate part; alternatively, the fender assembly 100 can be a sheet metal part or a plastic part. For example, the fender assembly 100 can be a plastic part and can be injection molded in one piece. The plastic can be a commonly used plastic material in engineering, such as PP+EPDM-T30 (PP: polypropylene, EPDM: ethylene propylene diene monomer rubber, where T30 indicates that the material contains 30% talc) material for injection molding.

[0072] Optionally, the air guide structure 2 and the fender body 1 can be integrally formed, and the air guide structure 2 can also be detachably connected to the fender body 1.

[0073] According to the embodiment of the present utility model, the fender assembly 100, by setting the air guide structure 2 on the outside of the fender body 1, facilitates the installation operation of the air guide structure 2, helps to reduce the installation difficulty of the air guide structure 2, and also helps to improve the setting flexibility of the air guide structure 2 and the air guide channel 3. The structural design of the air guide structure 2 can be adjusted more flexibly to optimize the air guiding effect of the air guide structure 2 on the vehicle.

[0074] refer to Figures 1-4 In some embodiments, the fender body 1 includes a first plate 11 and a second plate 12 connected to the first plate 11. The second plate 12 has an inwardly recessed portion 121. The air guide structure 2 is located outside the recessed portion 121 and defines an air guide channel 3 with the recessed portion 121. By forming the recessed portion 121 in the second plate 12 and defining the air guide channel 3 between the recessed portion 121 and the air guide structure 2, it is beneficial to increase the size of the air inlet 31 of the air guide channel 3, thereby increasing the air intake volume and improving the air resistance reduction effect of the air guide structure.

[0075] In addition, a semi-enclosed space is formed between the recessed portion 121 and the rear end of the air guide structure 2 to guide the airflow.

[0076] Optionally, the first plate 11 and the second plate 12 are detachably connected. The lower end of the first plate 11 is provided with a first connecting edge, and the upper end of the second plate 12 is provided with a second connecting edge, and the first connecting edge and the second connecting edge are fixedly connected.

[0077] refer to Figures 1-4 In some embodiments, the second plate 12 further includes a transition portion 122 connected to the recess 121. Along the length direction of the vehicle, the transition portion 122 is located behind the recess 121. The transition portion 122 is coplanar with the fender body 1. Coplanar arrangement helps to reduce turbulence and drag generated when airflow passes through, further optimizes the airflow path, and improves aerodynamic performance.

[0078] Optionally, the transition portion 122 and the fender body 1 form a continuous surface, which may be a plane or a smooth curved surface, etc.

[0079] By providing a transition portion 122 that connects to the recessed portion 121, the surface at the connection point between the second plate 12 and the other components becomes smoother, reducing turbulence and resistance generated when airflow passes through. This also enhances the overall visual appeal of the vehicle, making its appearance more modern and dynamic. Furthermore, it makes alignment and fixation easier during the installation of the fender assembly 100, reducing installation difficulty and time.

[0080] refer to Figures 1-5In some embodiments, the fender body 1 includes a first plate 11 and a second plate 12, and the air guiding structure 2 includes an outer air guiding plate 22. The outer air guiding plate 22 is disposed outside the second plate 12 and defines an air guiding channel 3 with the second plate 12. By including the outer air guiding plate 22 in the air guiding structure 2, the outer air guiding plate 22 has a guiding effect on the airflow, which facilitates precise control of the direction and angle of the airflow, reduces turbulence and improves aerodynamic performance.

[0081] For example, the second plate 12 includes a recess 121, and the air guide outer plate 22 and the recess 121 define the air guide channel 3.

[0082] Optionally, the air guide outer plate 22 can be fixed to the second plate 12 by welding, bonding or mechanical fasteners (such as bolts, clips, etc.) to ensure that it remains stable during vehicle operation and is not affected by vibration or impact.

[0083] During the production process of the fender assembly 100, the second plate 12 and the outer air guide plate 22 used to define the wall surface forming the air guide channel 3 can be treated with surface texture or paint, which helps to improve the aesthetics of the fender assembly 100.

[0084] Optionally, the connection relationship between the first plate 11, the second plate 12, and the air guide structure 2 can include the following situations: for example, there is a connection between any two of the first plate 11, the second plate 12, and the air guide structure 2; for example, the first plate 11 and the second plate 12 are connected, and the second plate 12 and the air guide structure 2 are connected, so that the three are integrated into a whole; for example, the first plate 11 and the air guide structure 2 are connected, and the air guide structure 2 and the second plate 12 are connected, so that the three are integrated into a whole; for example, the first plate 11 and the second plate 12 are connected, and the first plate 11 and the air guide structure 2 are connected, so that the three are integrated into a whole.

[0085] refer to Figures 1-2 In some embodiments, the second plate 12 is connected to the first plate 11, and the outer air guide plate 22 is connected to the second plate 12. By connecting the outer air guide plate 22 to the second plate 12, it is beneficial to achieve accurate positioning between the outer air guide plate 22 and the second plate 12, thereby improving the accuracy of the setting position of the air guide channel 3 and facilitating the effective air guiding function of the air guide channel 3.

[0086] Optionally, the second plate 12 is detachably connected to the first plate 11, and the air guide outer plate 22 is detachably connected to the second plate 12. For example, the first plate 11 and the second plate 12 are fastened together, and the second plate 12 and the air guide outer plate 22 are fastened together. This detachable connection method facilitates the maintenance, inspection, and replacement of the first plate 11, the second plate 12, and the air guide outer plate 22.

[0087] refer to Figure 1 and Figure 6 In some embodiments, the air guiding structure 2 further includes at least one air guiding column 21, which is located in the air guiding channel 3 and connected between the second plate 12 and the outer air guiding plate 22.

[0088] The air guiding structure 2 further includes at least one air guiding column 21, which may include the following scenarios: for example, the air guiding structure 2 includes one air guiding column 21. Or, for example, the air guiding structure 2 includes multiple air guiding columns 21.

[0089] By setting at least one air guide column 21, the air guide column 21 guides the airflow in the air guide channel 3, so that the airflow passes through the air guide channel 3 more smoothly.

[0090] refer to Figure 1 and Figure 6 In some embodiments, at least one air guide column 21 extends along the width direction of the vehicle and divides the air guide channel 3 into a plurality of sub-air guide channels 3 arranged along the height direction of the vehicle.

[0091] For example, the air guiding structure 2 includes an air guiding column 21 that divides the air guiding channel 3 into two sub-air guiding channels 3 arranged along the height direction of the vehicle. As another example, the air guiding structure 2 includes multiple air guiding columns 21, each air guiding column 21 dividing the air guiding channel 3 into two adjacent sub-air guiding channels 3 arranged along the height direction of the vehicle.

[0092] The air guide column 21 divides the air guide channel 3 into multiple sub-air guide channels 3 along the height direction of the vehicle, so that the airflow can be guided at different height levels. This helps to control the direction and speed of the airflow more precisely and improve aerodynamic performance. Multiple sub-air guide channels 3 can also make the airflow more evenly distributed around the wheels, avoiding excessive concentration or dispersion of local airflow, thereby optimizing airflow.

[0093] In addition, the air guide column 21 connects the second plate 12 and the outer air guide plate 22, which helps to enhance the connection strength and structural strength of the entire fender assembly 100, thereby improving the stability of the fender assembly 100 and preventing deformation or damage when driving at high speed or subjected to external impact.

[0094] refer to Figures 6-8In some embodiments, the end of the air guide column 21 near the air inlet 31 of the air guide channel 3 includes a first air guide surface 211 and a second air guide surface 212 facing away from each other. The first air guide surface 211 faces one side of the sub-air guide channel 3, and the second air guide surface 212 faces the other side of the sub-air guide channel 3. Along the air guide channel 3 from the air inlet 31 to the air outlet 32, the first air guide surface 211 is inclined towards one side of the sub-air guide channel 3, and the second air guide surface 212 is inclined towards the other side of the sub-air guide channel 3. Through the inclined design of the first air guide surface 211 and the second air guide surface 212, the airflow entering the air guide channel 3 can be accurately guided into the sub-air guide channels 3 on both sides, which can reduce the turbulence and flow generated when the airflow enters the sub-air guide channel 3, making the airflow more stable and reducing air resistance. In addition, the inclined design of the first air guide surface and the second air guide surface can reduce or avoid the large air resistance generated by the direct airflow of the air guide column 21.

[0095] refer to Figures 6-7 In some embodiments, the included angle between the first air guide surface 211 and the second air guide surface 212 is α, where α is greater than or equal to 20° and less than or equal to 60°. Exemplarily, α can be 20°, 30°, 40°, 45°, or 60°, etc.

[0096] If α is less than 20°, the guiding angle of the first guide surface 211 and the second guide surface 212 is small, resulting in poor airflow guidance. If α is greater than 60°, the guiding angle of the first guide surface 211 and the second guide surface 212 is large, which will generate greater resistance to airflow. By making the included angle between the first guide surface 211 and the second guide surface 212 greater than or equal to 20° and less than or equal to 60°, within this angle range, the guide column 21 has a good airflow guidance effect and is less likely to generate large air resistance.

[0097] refer to Figures 6-7 In some embodiments, the angle between the first air guide surface 211 and the second air guide surface 212 and the horizontal plane is greater than or equal to 40° and less than or equal to 45°. For example, α can be 40°, 41°, 42°, 43°, 44°, 45°, etc.

[0098] If α is less than 20°, the guiding angle of the first guide surface 211 and the second guide surface 212 is small, resulting in an unsatisfactory guiding effect on the airflow. If α is greater than 45°, the guiding angle of the first guide surface 211 and the second guide surface 212 is large, which will generate significant resistance to the airflow. By ensuring that the included angle between the first guide surface 211 and the second guide surface 212 is greater than or equal to 40° and less than or equal to 45°, within this angle range, the guide column 21 provides good airflow guidance and is less likely to generate significant air resistance.

[0099] refer to Figures 6-8In some embodiments, the air guide column 21 further includes a third air guide surface 213 and a fourth air guide surface 214 facing away from each other. One end of the third air guide surface 213 is connected to the other end of the first air guide surface 211, and one end of the fourth air guide surface 214 is connected to the other end of the third air guide surface 213. The third air guide surface 213 and the other end of the fourth air guide surface 214 are connected. By setting the third air guide surface 213 and the fourth air guide surface 214, and connecting the other end of the third air guide surface 213 and the other end of the fourth air guide surface 214, the connection of the third air guide surface 213 and the fourth air guide surface 214 can reduce the fluctuation and turbulence of the airflow in the air guide channel 3. Under the guidance of the air guide column 21, the airflow in the sub-air guide channels 3 on both sides is concentrated and flows out through the air outlet 32 ​​of the air guide channel 3, making the airflow more stable. It can also ensure unidirectional airflow, avoid backflow, and improve the efficiency of airflow.

[0100] refer to Figures 6-7 In some embodiments, the included angle between the third air guide surface 213 and the fourth air guide surface 214 is β, where β is greater than or equal to 20° and less than or equal to 60°. Exemplarily, β can be 20°, 30°, 40°, 45°, or 60°, etc.

[0101] If β is less than 20°, the guiding angles of the third guide surface 213 and the fourth guide surface 214 are small, resulting in an insignificant guiding effect on the airflow, which may cause the airflow to be obstructed when exiting through the air outlet 32 ​​of the guide channel 3. If β is greater than 60°, the guiding angles of the third guide surface 213 and the fourth guide surface 214 are large, causing the airflow to become too dispersed when approaching the air outlet 32, making it difficult to effectively guide the airflow to the air outlet 32. This will complicate the flow path of the airflow within the guide channel 3, reducing the airflow speed and pressure. By making the included angle between the first guide surface 211 and the second guide surface 212 greater than or equal to 40° and less than or equal to 45°, within this angle range, the guide column 21 has a good guiding effect on the airflow and can effectively guide the airflow to the air outlet 32.

[0102] refer to Figures 6-7 In some embodiments, the included angle between the third air guide surface 213 and the fourth air guide surface 214 is greater than or equal to 30° and less than or equal to 40°. For example, β can be 30°, 32°, 35°, 38°, 39°, 40°, etc.

[0103] By making the angle between the first air guide surface 211 and the second air guide surface 212 greater than or equal to 30° and less than or equal to 40°, within this angle range, the air guide column 21 has a better airflow guiding effect and can effectively guide the airflow to the air outlet 32.

[0104] refer to Figure 8In some embodiments, a first air guide fillet is connected between one end of the first air guide surface 211 and one end of the second air guide surface 212. The radius of the first air guide fillet is R1, which is greater than or equal to 1 mm and less than or equal to 3 mm. For example, the radius R1 of the first air guide fillet can be 1 mm, 1.2 mm, 1.5 mm, 2 mm, 2.8 mm, or 3 mm, etc.

[0105] By setting a first guide radius, the guide column 21 is easier to demold during the molding process. Furthermore, the first guide radius, being close to the air inlet 31 of the air guide channel 3, reduces the air resistance of the guide column 21. The first guide radius also smooths the transition between the first guide surface 211 and the second guide surface 212, reducing sudden changes in airflow at corners and lowering air resistance. If the radius of the first guide radius is less than 1mm, its effect on airflow is not significant. If the radius is greater than 3mm, the tilt angle between the first guide surface 211 and the second guide surface 212 connected to the first guide radius needs to be increased accordingly to ensure smooth airflow, which can easily lead to greater air resistance. By ensuring the radius of the first guide radius is greater than or equal to 1mm and less than or equal to 3mm, the air resistance generated by the guide column 21 can be effectively balanced, which is beneficial for optimizing the air guiding effect of the guide column 21.

[0106] refer to Figure 8 In some embodiments, a second air guide fillet is connected between the other end of the third air guide surface 213 and the other end of the fourth air guide surface 214. The radius of the second air guide fillet is R2, which is greater than or equal to 1 mm and less than or equal to 3 mm. For example, the radius R2 of the second air guide fillet can be 1 mm, 1.2 mm, 1.5 mm, 2 mm, 2.8 mm, or 3 mm, etc.

[0107] By setting a second air guide radius, the air guide column 21 is easier to demold during the molding process. The second air guide radius can smooth the transition between the third air guide surface 213 and the fourth air guide surface 214, reduce sudden changes in airflow at the corner, and optimize airflow. If the radius of the second air guide radius is less than 1mm, the effect of the second air guide radius on airflow is not obvious. If the radius of the second air guide radius is greater than 3mm, in order to ensure smooth airflow, the tilt angle of the third air guide surface 213 and the fourth air guide surface 214 connected to the second air guide radius needs to be increased accordingly, which causes the airflow to be too dispersed when approaching the air outlet 32. By making the radius of the second air guide radius greater than or equal to 1mm and less than or equal to 3mm, it is beneficial to optimize the air guiding effect of the air guide column 21.

[0108] refer to Figure 8In some embodiments, a third air guide fillet is connected between the other end of the first air guide surface 211 and one end of the third air guide surface 213. The radius of the third air guide fillet is R3, which is greater than or equal to 10 mm and less than or equal to 15 mm. For example, the radius R3 of the third air guide fillet can be 10 mm, 12 mm, 13 mm, 14 mm, or 15 mm, etc.

[0109] By setting a third air guide radius, the air guide column 21 is easier to demold during the molding process; the third air guide radius can smooth the transition between the first air guide surface 211 and the third air guide surface 213, reduce sudden changes in airflow at the corner, and optimize airflow. By making the radius of the third air guide radius greater than or equal to 10mm and less than or equal to 15mm, it is beneficial to optimize the air guiding effect of the air guide column 21.

[0110] refer to Figure 8 In some embodiments, a fourth air guide fillet is connected between the other end of the second air guide surface 212 and one end of the fourth air guide surface 214. The radius of the fourth air guide fillet is R4, which is greater than or equal to 10 mm and less than or equal to 15 mm. For example, the radius R4 of the fourth air guide fillet can be 10 mm, 12 mm, 13 mm, 14 mm, or 15 mm, etc.

[0111] By setting a fourth air guide radius, the air guide column 21 is easier to demold during the molding process; the fourth air guide radius can smooth the transition between the second air guide surface 212 and the fourth air guide surface 214, reduce sudden changes in airflow at the corner, and optimize airflow. By making the radius of the fourth air guide radius greater than or equal to 10mm and less than or equal to 15mm, it is beneficial to optimize the air guiding effect of the air guide column 21.

[0112] refer to Figure 8 In some embodiments, the radius of the first air guide rounded corner is R1, where R1 is greater than or equal to 1.5mm and less than or equal to 2mm, which is beneficial for further optimizing the air guiding effect of the air guide column 21. For example, the radius R1 of the first air guide rounded corner can be 1.5mm, 1.8mm, 1.9mm, 2mm, etc.

[0113] refer to Figure 8 The radius of the second air guide rounded corner is R2, which is greater than or equal to 1.5mm and less than or equal to 2mm, which is beneficial to further optimize the air guiding effect of the air guide column 21. For example, the radius R2 of the second air guide rounded corner can be 1.5mm, 1.8mm, 1.9mm, 2mm, etc.

[0114] refer to Figure 8The radius of the third air guide rounded corner is R3, which is greater than or equal to 12mm and less than or equal to 15mm, which is beneficial to further optimize the air guiding effect of the air guide column 21. For example, the radius R3 of the third air guide rounded corner can be 12mm, 12.5mm, 13mm, 14mm or 15mm, etc.

[0115] refer to Figure 8 The radius of the fourth air guide rounded corner is R4, which is greater than or equal to 12mm and less than or equal to 15mm, which is beneficial to further optimize the air guiding effect of the air guide column 21. For example, the radius R4 of the fourth air guide rounded corner can be 12mm, 12.5mm, 13mm, 14mm or 15mm, etc.

[0116] refer to Figures 6-9 In some embodiments, the cross-sectional profile of the air guide column 21 parallel to the reference plane is a parallelogram, and the reference plane is a plane perpendicular to the width direction of the vehicle.

[0117] It should be noted that the cross-sectional profile of the air guide column 21 parallel to the reference plane is approximately a parallelogram, but not limited to a parallelogram in an absolute sense. The shape of two opposite sides that are parallel or approximately parallel, as well as two other sides that are parallel or approximately parallel, are all within the scope of the parallelogram in this application. By making the cross-sectional profile of the air guide column 21 parallel to the reference plane a parallelogram, the air guide column 21 is easier to form.

[0118] It should be noted that the cross-section of the air guide column 21 parallel to the reference plane refers to the cross-section that is approximately parallel to the reference plane.

[0119] refer to Figure 9 In some embodiments, the cross-section of any air guide column 21 parallel to the reference plane is a first cross-section. The dimension of the first cross-section along the length of the air guide channel 3 is a, and the dimension of the first cross-section along the height of the vehicle is b. The ratio of the first dimension a to the second dimension b is greater than or equal to 2 and less than or equal to 4. If the ratio of the first dimension a to the second dimension b is less than 2, the air guiding angle of the outer surface of the air guide column 21 is small, and the air guiding effect is not ideal. If the ratio of the first dimension a to the second dimension b is greater than 4, the air guiding angle of the outer surface of the air guide column 21 is large, which will generate greater air resistance. By making the ratio of the first dimension a to the second dimension b greater than or equal to 2 and less than or equal to 4, the air guide column 21 has a good air guiding effect.

[0120] refer to Figure 6 In some embodiments, one end of the air guide column 21 is connected to the fender body 1, and the other end of the air guide column 21 is connected to the outer air guide plate 22. The area of ​​the cross-section of the air guide column 21 parallel to the reference plane gradually increases from one end to the other. This arrangement helps to improve the structural strength and stability of the air guide column 21.

[0121] In some optional embodiments, one end of the air guide column 21 is fastened to the fender assembly 100 via a first connector 6. A mounting recess is formed on the air guide column 21, and the first connector 6 is disposed on the mounting recess, ensuring that the connection between the air guide column 21 and the first connector 6 is not exposed, and that there are no exposed burrs or flash caused by seams on the surface. The forming and surface treatment processes are simple. For example, the first connector 6 is a self-tapping screw.

[0122] refer to Figures 3-5 In some embodiments, the first plate 11, the second plate 12, and the outer air guide plate 22 all include plate components and frame components. The frame components help improve the structural strength of the fender assembly 100. An adhesive layer 4 is provided between the plate components and the frame components. By providing the adhesive layer 4 between the plate components and the frame components, the connection strength between the plate components and the frame components is more uniform, and stress concentration is less likely to occur, which helps to improve the service life of the fender assembly 100. In addition, this also helps to reduce the overall thickness of the fender assembly 100.

[0123] refer to Figure 10 Optionally, the circumferential clearance between the plate body and the skeleton is 1 mm.

[0124] Optionally, the adhesive layer 4 forms a stable connection with the plate and the skeleton through a chemical reaction.

[0125] refer to Figures 3-5 In some embodiments, the first plate 11 includes a first plate member 13 and a first frame member 14, which are connected by an adhesive layer 4. The second plate 12 includes a first plate member 13 and a second frame member 16, which are connected by an adhesive layer 4. The air guide outer plate 22 includes a third plate member 221 and a third frame member 222, which are connected by an adhesive layer 4.

[0126] Optionally, the air guide column 21 is connected to the third frame member 222 and is integrally formed with the third frame member 222.

[0127] refer to Figures 3-5 In some embodiments, the adhesive layer 4 includes an edge portion whose contour shape matches the outer contour shape of the plate member; or, the contour shape of the edge portion matches the outer contour shape of the skeleton member. By matching the contour shape of the edge portion with the outer contour shape of the plate member; or, matching the contour shape of the edge portion with the outer contour shape of the skeleton member, it is beneficial to further enhance the connection strength between the plate member and the skeleton member, and improve the uniformity of the connection strength.

[0128] refer to Figures 3-5 In some embodiments, the adhesive layer 4 further includes a reinforcing portion connected to the inner side of the edge portion. By providing the reinforcing portion, the connection stability between the plate member and the skeleton member can be further enhanced.

[0129] refer to Figure 10 In some embodiments, at least one of the plate body and the skeleton member is provided with an adhesive groove 5, and the adhesive layer 4 is disposed in the adhesive groove 5. The outline shape of the adhesive groove 5 is adapted to the outline shape of the adhesive layer 4.

[0130] In this embodiment, at least one of the plate body and the skeleton member is provided with a glue-receiving groove 5, which may include the following situations: the plate body is provided with a glue-receiving groove 5, or the skeleton member is provided with a glue-receiving groove 5, or both the plate body and the skeleton member are provided with glue-receiving grooves 5. Optionally, the surfaces of the plate body and the skeleton member are recessed inward to form the glue-receiving groove 5, or the surfaces of the plate body and the skeleton member have opposing ribs that surround the glue-receiving groove 5.

[0131] By setting up the glue-containing tank 5, during the production process of the fender assembly 100, when applying the glue layer between the panel and the frame, the random flow and overflow of the glue can be reduced or avoided, thereby preventing waste or pollution.

[0132] refer to Figure 10 In some embodiments, the depth of the adhesive reservoir 5 is greater than or equal to 0.5 mm and less than or equal to 1.6 mm. For example, the depth of the adhesive reservoir 5 may be 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, or 1.6 mm, etc.

[0133] If the depth of the adhesive groove 5 is less than 0.5 mm, the amount of adhesive that can be held in the groove 5 is relatively small, resulting in a thin adhesive layer 4, which may lead to insufficient connection strength between the panel and the frame. If the depth of the adhesive groove 5 is greater than 1.6 mm, the adhesive layer 4 will be too thick, which may result in an excessively thick overall thickness of the fender assembly 100. By ensuring that the depth of the adhesive groove 5 is greater than or equal to 0.5 mm and less than or equal to 1.6 mm, the thickness of the adhesive layer 4 is appropriately balanced, ensuring both the connection strength between the panel and the frame without making the overall thickness of the fender assembly 100 excessive.

[0134] refer to Figure 10 The width of the adhesive reservoir 5 is greater than or equal to 20 mm and less than or equal to 25 mm. For example, the width of the adhesive reservoir 5 can be 20 mm, 21 mm, 22 mm, 24 mm or 25 mm, etc.

[0135] If the width of the adhesive reservoir 5 is less than 20mm, the amount of adhesive that can be held in the reservoir 5 is relatively small, resulting in a narrow adhesive layer 4, which may lead to insufficient connection strength between the board and the skeleton. If the depth of the adhesive reservoir 5 is greater than 25mm, it may cause unnecessary waste of adhesive. By making the width of the adhesive reservoir 5 greater than or equal to 20mm and less than or equal to 25mm, the width of the adhesive layer 4 is made appropriate, which can ensure the connection strength between the board and the skeleton without causing adhesive waste.

[0136] refer to Figures 1-5 In some embodiments, the first plate 11 and the second plate 12 are detachably connected. By making the first plate 11 and the second plate 12 detachably connected, the first plate 11 and the second plate 12 can be disassembled, installed, and maintained separately. For example, during the installation of the fender assembly 100 onto the vehicle body, the first plate 11 can be installed along the height direction of the vehicle body, and the second plate 12 can be installed along the width direction of the vehicle body, which helps to reduce the installation difficulty of the fender assembly 100.

[0137] refer to Figure 1 In some embodiments, the air inlet 31 of the air guide channel 3 faces the vehicle's wheels, and the airflow area of ​​the air inlet 31 of the air guide channel 3 is larger than the airflow area of ​​the air outlet 32 ​​of the air guide channel 3. This helps to improve the streamline of the airflow entering the air guide channel 3 and optimize aerodynamics.

[0138] In some embodiments, both the fender body 1 and the air guide structure 2 are made of plastic. By making both the fender assembly 100 body and the air guide structure 2 made of plastic, it is beneficial to reduce the weight of the fender assembly 100, and the high connection strength between the plastic parts and the adhesive layer 4 helps to improve connection stability.

[0139] A second aspect of this utility model provides a vehicle that includes the fender assembly 100 described above.

[0140] According to the vehicle of this utility model embodiment, by setting the above-mentioned fender assembly 100, the air guide structure 2 is located on the outside of the fender body 1, which facilitates the installation operation of the air guide structure 2, helps to reduce the installation difficulty of the air guide structure 2, and also helps to improve the setting flexibility of the air guide structure 2 and the air guide channel 3. The structural design of the air guide structure 2 can be adjusted more flexibly to optimize the air guiding effect of the air guide structure 2 on the vehicle.

[0141] The air guide structure 2 of the fender assembly 100 is located on the outside of the fender body 1, and the air guide channel 3 is also located on the outside of the fender body 1. This means that when the fender assembly 100 is used in a vehicle, the obstruction of the airflow through the air guide channel 3 by other components connected to the fender assembly 100 is minimal. This reduces the structural design requirements of these components on the fender assembly 100, thereby reducing the complexity of their structural design and the difficulty of their molding. For example, during the design and molding process of the door, the air outlet 32 ​​of the air guide channel 3 is exposed on the outside of the door, eliminating the need for a significant inward concavity design relative to the fender body 1, thus reducing the complexity of the door's structural design and the difficulty of its molding.

[0142] In some embodiments, the vehicle further includes a door, with a gap between the door and the outer surface of the air guide structure 2 along the width direction of the vehicle. The door is located inside the outer surface of the air guide structure 2, and at least a portion of the air outlet 32 ​​of the air guide channel 3 is exposed through the gap. By creating a gap between the door and the outer surface of the air guide structure 2 along the width direction of the vehicle, the door is prevented from obstructing the airflow through the air outlet 32 ​​of the air guide channel 3, thereby further improving the air guiding effect of the air guide structure 2 and reducing air resistance to the vehicle.

[0143] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
