DETAILED DESCRIPTION

[0027] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the accompanying drawings required by the embodiments or the prior art description will be briefly introduced. Obviously, those skilled in the art can obtain other drawings according to these drawings without any creative effort.

[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced without the specific details. In other instances, well-known methods, procedures and components have not been described in detail so as not to obscure the present application.

[0029] REFERENCE Figures 1 to 5As shown, the first aspect of the present application provides a vehicle rear wheel air guide structure, comprising an air guide piece 1, a rear wheel cover 2, and a sheet metal longitudinal beam 3 arranged on the side of the rear wheel cover 2 close to the vehicle head; the end of the sheet metal longitudinal beam 3 is formed with a process port; the air guide piece 1 comprises a mounting part 11, an air guide part 12 arranged on the mounting part 11, and a limiting part 13, the mounting part 11 is fixedly connected with the rear wheel cover 2, the air guide part 12 extends downward and is located below the rear wheel cover 2, and the limiting part 13 is inserted into the process port and abuts and supports on the bottom wall of the process port.

[0030] Firstly, the existing air guide structure is arranged on the lower side of the rear wheel cover, the air guide structure is connected with the lower side of the rear wheel cover through bolts or rivets, and a part of the air guide structure extends downward to serve as a baffle. The baffle can guide air flow and block the direct impact of water on the rear wheels of the vehicle when the vehicle is wading, so that the baffle can reduce the wind resistance of the vehicle during driving and the resistance when the vehicle is wading. However, during driving of the vehicle, the baffle will be subjected to a force towards the direction of the tail of the vehicle due to the impact of wind and water, and the force acting on the baffle will cause the air guide structure to overturn towards the tail with the connection between the air guide structure and the rear wheel cover as the turning point. The continuous driving of the vehicle will cause the air guide structure to be continuously stressed, causing the connection point between the rear wheel cover and the air guide structure to loosen, and causing the air guide structure to overturn and sag relative to the rear wheel cover.

[0031] The overturning and sagging of the air guide structure will cause the position of the baffle to deviate, reducing the area of the baffle that can guide air flow and block the impact of water, reducing the effect of the air guide structure in guiding air flow and blocking the direct impact of water on the rear wheels of the vehicle, increasing the resistance of the vehicle during driving, and the overturning and sagging of the air guide structure will also cause a gap between the air guide structure and the rear wheel cover. When the vehicle is driving, air will blow into the gap, and when the vehicle is wading, water will also flow into the gap, increasing the resistance of the vehicle during driving.

[0032] In the prior art, in order to increase the stability of the air guide structure, the part connected with the rear wheel cover of the air guide structure is extended, and a mounting hole is arranged on the vehicle chassis. The extended part of the air guide structure is connected with the mounting hole through bolts or rivets to fix the extended part of the air guide structure on the vehicle chassis. However, the air guide structure is fixedly connected with the chassis of the vehicle, which requires the mounting hole to be arranged on the chassis of the vehicle, damaging the structure of the chassis of the vehicle, increasing the assembly process, and affecting the cost of the vehicle.

[0033] However, the rear wheel air guide structure provided in this application has an installation part 11 fixedly connected to the rear wheel cover 2, an air guide part 12 extending downward to guide the airflow at the rear wheel of the vehicle, and an air guide part 12 blocking water from directly impacting the rear wheel of the vehicle when the vehicle is wading through water; a limiting part 13 is inserted into the process port and abuts against the bottom wall of the process port. When the air guide 1 flips and droops towards the rear wheel of the vehicle, it will drive the limiting part 13 to move downward. The impact force on the air guide part 12 towards the rear of the vehicle can be transmitted to the bottom wall of the process port through the limiting part 13, so that the sheet metal longitudinal beam 3 can support the limiting part 13 to restrict the downward movement of the limiting part 13, thereby preventing the air guide 1 from flipping and drooping towards the rear wheel of the vehicle, avoiding the air guide 1 from flipping and drooping and increasing the resistance of the vehicle, and improving the stability of the air guide 1 on the rear wheel cover 2. The limiting part 13 is connected to the process port of the sheet metal longitudinal beam 3 of the vehicle, which can prevent the air guide 1 from flipping and sagging. This makes reasonable use of the existing structure of the vehicle, and the air guide 1 can be prevented from flipping and sagging without drilling mounting holes on the vehicle chassis, thus avoiding damage to the vehicle chassis, simplifying the assembly operation of the air guide 1 and the vehicle, and reducing vehicle costs.

[0034] Specifically, the direction vertically away from the ground is considered "up," and the direction vertically towards the ground is considered "down." The direction from which the front of the vehicle faces the rear, or vice versa, is the vehicle's longitudinal direction. The horizontal direction perpendicular to the vehicle's longitudinal direction is the vehicle's lateral direction.

[0035] A vehicle has front wheels and rear wheels. The front wheels are located on the chassis near the front of the vehicle, and the rear wheels are located on the chassis near the rear of the vehicle. Common vehicles have at least two rear wheels and two front wheels, with the two rear wheels positioned laterally opposite each other.

[0036] The sheet metal longitudinal beam 3 extends longitudinally along the vehicle. The rear wheel arch 2 is mounted on the vehicle chassis and is used to accommodate the rear wheels. The sheet metal longitudinal beam 3 is mounted on the vehicle chassis, and the rear wheel arch 2 is located on the lateral edge of the vehicle chassis. Furthermore, the sheet metal longitudinal beam 3 is located on the side of the rear wheel arch 2 closest to the front of the vehicle, meaning it is longitudinally positioned on the side of the rear wheel arch 2 closest to the front of the vehicle and is opposite to the rear wheel arch 2.

[0037] The vehicle chassis has two rear wheel arches 2 and two sheet metal longitudinal beams 3 installed on opposite sides of the vehicle's transverse sides. Each rear wheel arch 2 can be equipped with a wind guide 1. The wind guide 1 is located on the edge of the rear wheel arch 2 near the front of the vehicle, so that the wind guide 1 can block the wind and water from directly impacting the rear wheels of the vehicle when the vehicle is moving forward.

[0038] The mounting portion 11, air guide portion 12, and limiting portion 13 of the air guide component 1 can all be panel structures. The mounting portion 11 can be connected to the lower edge of the rear wheel arch 2, or it can be connected to the outer side of the rear wheel arch 2 near the sheet metal longitudinal beam 3, or it can be connected to the inner side of the rear wheel arch 2. The air guide portion 12 can be located below the mounting portion 11 and extend downwards, so that the air guide portion 12 is located on the side of the vehicle's rear wheel near the front of the vehicle, so that the air guide portion 12 guides the airflow to avoid the wind blowing directly onto the rear wheel of the vehicle inside the rear wheel arch 2 and to prevent water from directly impacting the rear wheel of the vehicle when the vehicle is wading through water. The limiting portion 13 can be a flat plate, or it can be composed of multiple plates that are inclined to each other and connected in sequence. The limiting portion 13 extends toward the sheet metal longitudinal beam 3, and after the limiting portion 13 is inserted into the process opening, it fits against the bottom wall of the process opening.

[0039] The aforementioned sheet metal longitudinal beam 3, when installed on the vehicle chassis, can improve the structural strength of the vehicle chassis. In order to reduce the weight of the sheet metal longitudinal beam 3, the interior of the sheet metal longitudinal beam 3 is hollow. Alternatively, a channel structure can be formed inside the sheet metal longitudinal beam 3, and a process port can be formed at both ends of the channel structure. The inner wall of the channel structure on the side closer to the bottom in the vertical direction is the bottom wall of the process port, and process ports will be formed at both ends of the sheet metal longitudinal beam 3.

[0040] Alternatively, the sheet metal longitudinal beam 3 can be cut and drilled from one end to the other during processing to form a channel inside the sheet metal longitudinal beam 3, thereby reducing the weight of the sheet metal longitudinal beam 3. After the sheet metal longitudinal beam 3 is processed, one end has an opening as a process port, and the other end is closed. The side of the channel inside the sheet metal longitudinal beam 3 that is closer to the ground is the bottom wall of the process port. The end of the sheet metal longitudinal beam 3 with the process port is set towards the rear wheel cover 2 so that after the air guide 1 is installed on the rear wheel cover 2, the limiting part 13 can be inserted into the process port.

[0041] The inner wall of the sheet metal longitudinal beam 3 on the side closest to the ground is the bottom wall of the process port. The limiting part 13 is inserted into the process port and abuts against the bottom wall, so that the bottom wall of the process port can support the limiting part 13 and restrict the limiting part 13 from moving downward.

[0042] The lower edge of the rear wheel cover 2 near the ground is the lower edge. The lower edge of the rear wheel cover 2 can be located on the upper side of the sheet metal longitudinal beam 3, so that the process port of the sheet metal longitudinal beam 3 facing the rear wheel cover 2 is located on the upper side of the lower edge of the rear wheel cover 2. The limiting part 13 can be extended upward first and then towards the sheet metal longitudinal beam 3, so that the end of the limiting part 13 can be inserted into the process port; or the limiting part 13 can be extended in a direction that is inclined upward in a relatively horizontal direction, so that the limiting part 13 can be inserted into the process port of the sheet metal longitudinal beam 3.

[0043] Alternatively, the lower edge of the rear wheel arch 2 can be positioned at the same height as the sheet metal longitudinal beam 3, so that the process opening of the sheet metal longitudinal beam 3 is at the same height as the rear wheel arch 2. The limiting part 13 can then be inserted into the process opening of the sheet metal longitudinal beam 3 by extending along the horizontal direction of the vehicle towards the sheet metal longitudinal beam 3.

[0044] The rear wheel air guide structure provided in this application includes an air guide 1, a rear wheel cover 2, and a sheet metal longitudinal beam 3 disposed on the rear wheel cover 2 near the front of the vehicle. The end of the sheet metal longitudinal beam 3 facing the rear wheel cover 2 has a process opening. The air guide 1 includes a mounting part 11, an air guide part 12 disposed on the mounting part 11, and a limiting part 13. The mounting part 11 is fixedly connected to the rear wheel cover 2. The air guide part 12 extends downward and is located below the rear wheel cover 2. The limiting part 13 is inserted into the process opening and abuts against and is supported on the bottom wall of the process opening. The air guide part 12 extends downward to guide the airflow at the rear wheel of the vehicle and to block water from directly impacting the rear wheel of the vehicle, thereby reducing the resistance when the vehicle is driving. When the air guide 1 is impacted and flips down, it will drive the limiting part 13 to move downward. The bottom wall of the process opening supports the limiting part 13 and restricts the downward movement of the limiting part 13, thereby preventing the air guide 1 from flipping down. The limiting part 13 is connected to the process port of the sheet metal longitudinal beam 3 of the vehicle, which can prevent the air guide 1 from flipping and sagging. This makes reasonable use of the existing structure of the vehicle without adding mounting holes on the vehicle chassis, avoiding damage to the vehicle chassis, simplifying the assembly operation of the air guide 1 and the vehicle, and reducing vehicle costs.

[0045] In specific use, the rear wheel air guide structure provided in this application embodiment involves first installing a sheet metal longitudinal beam 3 on the vehicle chassis, then fixing the mounting part 11 to the rear wheel arch 2 to install the air guide 1 on the rear wheel arch 2. The rear wheel arch 2 with the air guide 1 installed is then assembled onto the vehicle chassis. During assembly, the limiting part 13 on the mounting part 11 is inserted into the process port of the sheet metal longitudinal beam 3. The air guide 12 is located on the side of the rear wheel near the front of the vehicle, allowing it to guide airflow and prevent wind from directly blowing onto the rear wheel, as well as preventing water from directly impacting the rear wheel. When the vehicle is in motion, the impact force of air and water on the air guide 12 is transmitted to the sheet metal longitudinal beam 3 through the limiting part 13. The sheet metal longitudinal beam 3 restricts the movement of the limiting part 13, preventing the air guide 1 from flipping and sagging, thus avoiding increased vehicle drag.

[0046] Reference Figure 3 and Figure 4 As shown, in some embodiments, a guide slope 133 is formed on the lower surface of the end of the limiting part 13, and the limiting part 13 is inserted into the process port through the guide slope 133.

[0047] With this configuration, during the insertion of the limiting part 13 into the process port, the guiding inclined surface 133 first abuts against the lower edge of the process port, and then the guiding inclined surface 133 slides relative to the lower edge of the process port, so that the limiting part 13 can be gradually inserted into the process port, thereby improving the convenience of inserting the limiting part 13 into the process port of the sheet metal longitudinal beam 3.

[0048] Specifically, the end of the limiting part 13 away from the mounting part 11 can be tilted upwards as a whole, so that a guide slope 133 is formed on the lower side of the limiting part 13. Alternatively, the lower side of the limiting part 13 away from the mounting part 11 can be cut, or the lower side of the limiting part 13 away from the mounting part 11 can be deformed, thereby forming a guide slope 133 on the lower side of the limiting part 13 away from the mounting part 11.

[0049] During vehicle assembly, the rear wheel arch 2 is first separated from the vehicle chassis. The air guide 1 is then fixedly connected to the rear wheel arch 2. The rear wheel arch 2, with the air guide 1 installed, is then assembled onto the vehicle chassis. Simultaneously, the limiting part 13 is inserted into the process opening of the sheet metal longitudinal beam 3 during the assembly of the rear wheel arch 2. When the limiting part 13 is inserted into the process opening, the guide slope 133 first abuts against the lower edge of the process opening of the sheet metal longitudinal beam 3. As the rear wheel arch 2 is assembled, the limiting part 13 gradually moves towards the front of the vehicle, causing the guide slope 133 to slide relative to the edge of the process opening, thus guiding the limiting part 13 into the process opening.

[0050] Reference Figures 1 to 4 As shown, in some embodiments, the rear wheel arch 2 includes a wheel arch body 21 and a skirt 22. A sheet metal longitudinal beam 3 is disposed on the side of the wheel arch body 21 near the front of the vehicle. The skirt 22 is formed at least on the lower edge of the wheel arch body 21 near the sheet metal longitudinal beam 3. The mounting part 11 is fixedly connected to the lower side of the skirt 22.

[0051] With this configuration, the skirt 22 can increase the area for fixed connection with the mounting part 11, making it easier for the mounting part 11 to be fixed on the rear wheel cover 2. Furthermore, since the mounting part 11 is on the lower edge of the rear wheel cover 2, it is convenient for the air guide part 12 to extend to the lower side of the rear wheel cover 2 to guide airflow and block water flow from directly impacting the rear wheel of the vehicle, thereby reducing the volume required for the air guide part 12 and saving the manufacturing cost of the air guide part 1.

[0052] Specifically, the wheel cover body 21 is an arc-shaped plate with an opening facing downwards, so that the wheel cover body 21 forms a downward-facing receiving space on the vehicle chassis, and the rear wheels of the vehicle can be placed in the receiving space inside the wheel cover body 21; the edges at both ends of the wheel cover body 21 are the lower edges of the wheel cover body 21, and it is possible to form a skirt 22 on both lower edges of the wheel cover body 21, or a skirt 22 can be formed on the lower edge of the wheel cover body 21 near the sheet metal longitudinal beam 3.

[0053] The aforementioned skirt panel 22 can be a plate structure. It can extend either away from the interior of the wheel arch body 21 or towards the interior of the wheel arch body 21. The skirt panel 22 has a large area, facilitating its connection to the mounting part 11. The mounting part 11 fits against the lower side of the skirt panel 22 and is fixedly connected to it. The mounting part 11 can be connected to the skirt panel 22 by riveting or by bolting.

[0054] Reference Figures 1 to 4 As shown, in some embodiments, the mounting part 11 is provided with an upwardly extending positioning plate 111, which abuts against the edge of the skirt 22 away from the wheel cover body 21. With this arrangement, the positioning plate 111 and the skirt 22 cooperate with each other to position the relative positions of the mounting part 11 and the skirt 22, facilitating the fixed connection operation between the mounting part 11 and the skirt 22.

[0055] Specifically, the positioning plate 111 can be perpendicular to the mounting part 11, or it can be inclined relative to the mounting part 11. The positioning plate 111 is located on the upper side of the mounting part 11, and it can abut against the edge of the skirt 22 away from the wheel arch body 21 on the upper side of the mounting part 11. The lower edge of the wheel arch body 21 is an arc-shaped edge, which is recessed towards the inside of the vehicle in the lateral direction. The skirt 22 is on the arc-shaped edge, and the edge of the skirt 22 away from the wheel arch body 21 is also arc-shaped. The positioning plate 111 can be an arc with the same curvature as the edge of the skirt 22 away from the wheel arch body 21, so that the positioning plate 111 can fit and abut against the edge of the skirt 22 away from the wheel arch body 21.

[0056] When the mounting part 11 is installed on the skirt panel 22, the positioning plate 111 can be first brought into contact with the edge of the skirt panel 22 away from the wheel cover body 21, and then the mounting part 11 can be rotated toward the skirt panel 22 with the position where the positioning plate 111 and the skirt panel 22 are in contact as the rotation point, so that the mounting part 11 can be attached to the lower side of the skirt panel 22. When the mounting part 11 is attached to the skirt panel 22, the contact between the edge of the positioning plate 111 and the skirt panel 22 can limit the relative position between the mounting part 11 and the skirt panel 22, so that the mounting part 11 can be fixed to the skirt panel 22 by riveting, bolting or welding.

[0057] Reference Figures 1 to 4 As shown, in some embodiments, the lower edge of the rear wheel arch 2 extends to the lower side of the sheet metal longitudinal beam 3, and the mounting part 11 is fixedly connected to the lower edge of the rear wheel arch 2. This arrangement increases the protection range of the rear wheel arch 2 for the vehicle's rear wheels.

[0058] Specifically, the sheet metal longitudinal beam 3 is positioned vertically above the lower edge of the rear wheel cover 2, so that the process port is above the lower edge of the rear wheel cover 2; there is a gap between the process port and the lower edge of the rear wheel cover 2 in the vertical direction, and the limiting part 13 extends upward to adapt to the relative position of the rear wheel cover 2 and the sheet metal longitudinal beam 3, so that the limiting part 13 can be inserted and connected with the process port.

[0059] Reference Figures 2 to 4 As shown, in some embodiments, the limiting part 13 includes a support plate 131 and an abutment plate 132. The support plate 131 is connected to the mounting part 11, and the abutment plate 132 is connected to the end of the support plate 131 away from the mounting part 11. The support plate 131 extends upward, and the abutment plate 132 is inserted into the process port and partially abuts against and supports the bottom wall of the process port.

[0060] With this configuration, the support plate 131 occupies less space in the longitudinal direction of the vehicle, allowing the limiting part 13 to fit the space between the rear wheel arch 2 and the sheet metal longitudinal beam 3. The abutment plate 132 extends toward the sheet metal longitudinal beam 3, allowing the abutment plate 132 to have a larger contact area with the inner wall of the sheet metal longitudinal beam 3, thereby improving the stability of the inner wall of the sheet metal longitudinal beam 3 in supporting the abutment plate 132.

[0061] Specifically, the support plate 131 can extend upwards, and the abutment plate 132 can extend toward the sheet metal longitudinal beam 3, so that the abutment plate 132 can be inserted into the process opening of the sheet metal longitudinal beam 3; the support plate 131 can extend upwards perpendicular to the mounting part 11, and the abutment plate 132 can extend perpendicular to the support plate 131 and toward the front of the vehicle, so that the support plate 131 and the abutment plate 132 can form an "L" shaped plate structure; the abutment plate 132 can be inserted into the process opening of the sheet metal longitudinal beam 3, and the abutment plate 132 abuts against the inner wall of the lower side of the sheet metal longitudinal beam 3, so that the sheet metal longitudinal beam 3 restricts the abutment plate 132 from moving downwards.

[0062] The aforementioned support plate 131 and abutment plate 132 can be an integrated structure, or they can be connected by welding. Since the rear wheel arch 2 and the sheet metal longitudinal beam 3 are close in the longitudinal direction of the vehicle, the space between the rear wheel arch 2 and the sheet metal longitudinal beam 3 is limited. Extending the support plate 131 upward can reduce the space occupied by the support plate 131 in the longitudinal direction of the vehicle. The abutment plate 132 can reach the same height as the process port on the support plate 131, so that the abutment plate 132 can be inserted into the process port.

[0063] Reference Figure 4 As shown, in some embodiments, the mounting portion 11 is provided with a plurality of spaced-apart riveting points, which are riveted to the rear wheel cover 2. This arrangement provides multiple connection points between the mounting portion 11 and the rear wheel cover 2, improving the stability of the connection between the mounting portion 11 and the rear wheel cover 2.

[0064] Specifically, the riveting points on the mounting part 11 can be spaced out horizontally on the mounting part 11. When the lower edge of the rear wheel cover 2 is an arc-shaped edge, the mounting part 11 can be selected to extend along the arc length of the arc-shaped edge, and the riveting points can be spaced out along the extension direction of the mounting part 11. The riveting points can be through holes, with corresponding openings provided on the lower edge of the rear wheel cover 2. The mounting part 11 is fitted to the lower edge of the rear wheel cover 2, making the through hole and the opening coaxial. Rivets are then passed through the through hole and the opening to rivet the mounting part 11 to the rear wheel cover 2.

[0065] Reference Figure 5 As shown, in some embodiments, the sheet metal longitudinal beam 3 has multiple partitions 31 inside, which divide the process port into multiple sub-openings 32. The limiting part 13 is inserted into one of the sub-openings 32 and abuts against the bottom wall of the corresponding sub-opening 32.

[0066] With this configuration, the partition 31 supports the sheet metal longitudinal beam 3 within the sheet metal longitudinal beam 3, thereby improving the structural strength of the sheet metal longitudinal beam 3; the limiting part 13 is inserted into any of the sub-openings 32, so that the bottom wall of the corresponding sub-opening 32 can restrict the limiting part 13 from moving downward, thus achieving the effect of preventing the air guide 1 from flipping and sagging.

[0067] Specifically, the partitions 31 can extend longitudinally along the vehicle. Some partitions 31 are arranged horizontally, while the remaining partitions are arranged vertically. These partitions are interconnected, dividing the internal space of the sheet metal longitudinal beam 3 into multiple sub-channels along the vehicle's longitudinal direction. The opening of each sub-channel near the end of the rear wheel arch 2 is a sub-opening 32, meaning the process entrance is divided into multiple sub-openings 32 by the partitions 31. The bottom wall of the sub-opening 32 is the inner wall of the corresponding sub-channel near the ground.

[0068] When the sheet metal longitudinal beam 3 and the lower edge of the rear wheel arch 2 are at the same height, the limiting part 13 can be inserted into the corresponding sub-channel through any one of the sub-openings 32. When the sheet metal longitudinal beam 3 is above the lower edge of the rear wheel arch 2, the limiting part 13 can be inserted into the corresponding sub-channel through the lowermost of the multiple sub-openings 32. Of course, the limiting part 13 can also be inserted into the corresponding sub-channel through other sub-openings 32, as long as the bottom wall of the sub-opening 32 into which the limiting part 13 is inserted can support the limiting part 13, thereby restricting the downward movement of the limiting part 13 and preventing the air guide 1 from flipping and drooping.

[0069] Reference Figures 2 to 4As shown, in some embodiments, a rib 14 is connected between the air guide section 12 and the mounting section 11 on the side facing the sheet metal longitudinal beam 3. With this arrangement, the rib 14 improves the stability of the relative position of the air guide section 12 and the mounting section 11, and prevents the air guide section 12 from deforming towards the rear wheel of the vehicle due to impact, thereby increasing the resistance of the vehicle.

[0070] Specifically, the rib 14 is connected to the air guide 12 on one side in the horizontal direction and to the mounting part 11 on the upper side in the vertical direction. When the air guide 12 is subjected to a force along the longitudinal direction of the vehicle, the force on the air guide 12 can be transmitted to the mounting part 11 through the rib 14.

[0071] A second aspect of this application provides a vehicle including a rear wheel air guide structure as described in any of the preceding claims.

[0072] Specifically, the rear wheel air guide structure is set at the rear wheel of the vehicle. The mounting part 11 is fixedly connected to the rear wheel cover 2. The air guide part 12 is on the side of the rear wheel near the front of the vehicle. The limiting part 13 is inserted into the process port of the sheet metal longitudinal beam 3 so that the bottom wall of the process port can support the limiting part 13 to prevent the air guide 1 from being flipped and drooping due to the impact of air and water accumulation.

[0073] When the rear wheel air guide mechanism provided in this application is used in the vehicle, the sheet metal longitudinal beam 3 is first assembled on the chassis of the vehicle. Then, the positioning plate 111 is fitted and abutted against the edge of the skirt 22 away from the wheel cover body 21, so that the mounting part 11 is fitted against the lower side of the skirt 22. Multiple rivet points on the mounting part 11 are riveted to the skirt 22 to install the air guide 1 on the rear wheel cover 2.

[0074] The rear wheel arch 2, equipped with the air guide 1, is mounted on the vehicle chassis. During assembly, the abutment plate 132 is inserted into the corresponding sub-channel through a sub-opening 32 on the sheet metal longitudinal beam 3, and the abutment plate 132 abuts against the inner wall of the lower side of the inserted sub-channel. After the vehicle assembly is completed, the air guide 12 is located in front of the rear wheel. When the vehicle moves forward, air blows onto the air guide 12, allowing the air guide 12 to guide the airflow in front of the rear wheel. When the vehicle is wading through water, the water impacts the air guide 12 without directly impacting the rear wheel. The impact of the wind and water on the air guide 12 creates a tendency for the air guide 1 to flip towards the rear wheel. The flipping tendency of the air guide 1 causes the limiting part 13 to move downward. The inner wall of the sub-channel supports the limiting part 13, thus restricting the flipping of the air guide 1 and keeping the air guide 1 stable relative to the rear wheel arch 2 and the sheet metal longitudinal beam 3, preventing the air guide 1 from flipping and sagging, which would increase the resistance of the vehicle.
