Description

Technical Field

[0001] This invention relates to an automotive component, and more particularly to a heavy-duty vehicle splash guard assembly. Background Technology

[0002] To reduce the splashing of mud and dust, heavy-duty trucks are usually equipped with mudguards. However, existing mudguards generate considerable noise at high speeds because they obstruct airflow and mud. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a heavy-duty vehicle anti-splash mudguard assembly, which overcomes the shortcomings of the prior art and reduces the noise generated at the mudguard when the vehicle is traveling at high speed.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows.

[0005] A heavy-duty vehicle splash guard assembly includes a base plate and a mesh plate. The base plate has several mounting holes for fixing to the vehicle body. A slot is provided on the bottom edge of the base plate. Limiting strips are provided on both sides of the bottom of the slot. A through groove is provided on the side wall of the slot. An insert is provided on the top of the mesh plate to engage with the slot. The insert is inserted into the slot and limited by the limiting strips. A hollow cylinder is provided on the side of the mesh plate facing away from the wheel. An opening is provided on the side wall of the hollow cylinder. A connecting shaft is installed inside the hollow cylinder. A flexible baffle is connected to the connecting shaft. Several positioning holes are provided on the end of the hollow cylinder facing the outside of the wheel. A threaded hole is provided on the connecting shaft. The installation angle of the flexible baffle can be adjusted by aligning the threaded hole with different positioning holes and locking it with bolts.

[0006] Preferably, the side of the mesh plate facing the wheel is detachably fitted with a flexible protective layer.

[0007] Preferably, the flexible baffle is provided with a flow guide hole, and a baffle mechanism is provided on the outside of the flow guide hole.

[0008] Preferably, the flow guide hole includes an upper first flow guide hole portion and a lower second flow guide hole portion, with a partition plate provided between the first flow guide hole portion and the second flow guide hole portion, and the diameter of the second flow guide hole portion is larger than the diameter of the first flow guide hole portion.

[0009] Preferably, the baffle mechanism includes a first baffle and a second baffle. The top end of the first baffle is connected to the upper part of the first guide hole via a torsion spring, and the bottom end of the second baffle is connected to the lower part of the second guide hole via a torsion spring. The second baffle is located inside the first baffle. A groove is provided on the inner side of the bottom edge of the first baffle, and a flexible limiting block is provided on the bottom edge of the second baffle that slides in contact with the inner side of the groove. When the flexible limiting block moves into the groove, the groove restricts the flexible limiting block from continuing to slide, so as to prevent the second baffle from separating from the first baffle. A wire mesh part is provided on the top of the first baffle, and a through hole is provided on the bottom of the second baffle.

[0010] The beneficial effects of adopting the above technical solution are as follows: This invention reduces the impact of mud, water, and sand on the mudguard structure, as well as the noise generated by airflow. It is low in cost, easy to use, and highly durable. Attached Figure Description

[0014] Reference Figure 1-3One specific embodiment of the present invention includes a base plate 1 and a mesh plate 6. The base plate 1 is provided with a plurality of mounting holes 2 for fixing to the vehicle body. A slot 3 is provided on the bottom edge of the base plate 1. Limiting strips 4 are provided on both sides of the bottom of the slot 3. Through grooves 5 are provided on the side wall of the slot 3. An insert 7 is provided on the top of the mesh plate 6 to engage with the slot 3. The insert 7 is inserted into the slot 3 and limited by the limiting strips 4. A hollow cylinder 8 is provided on the side of the mesh plate 6 facing away from the wheel. An opening 9 is provided on the side wall of the hollow cylinder 8. A connecting shaft 10 is installed inside the hollow cylinder 8. A flexible baffle 11 is connected to the connecting shaft 10. A plurality of positioning holes 12 are provided on the end of the hollow cylinder 8 facing the outside of the wheel. A threaded hole (not shown in the figure) is provided on the connecting shaft 10. The installation angle of the flexible baffle 11 can be adjusted by aligning the threaded hole with different positioning holes 12 and locking it with bolts 13. A flexible protective layer 14 is detachably installed on the side of the mesh plate 6 facing the wheel. In use, select the appropriate base plate 1 according to the vehicle body structure and fix the base plate 1 to the vehicle body through the mounting holes 2. Then insert the mesh plate 6 into the slot 3 and fix it with screws through the through slot 5. Then adjust the flexible baffle 11 according to the driving conditions (reduce the initial angle of the flexible baffle 11 when the driving speed is low or the road surface is relatively clean, and increase the initial angle of the flexible baffle 11 when the driving speed is high) to make the flexible baffle 11 at the optimal initial angle, and fix the connecting shaft 10 with bolts 13. The mesh plate 6 is used to block sand and gravel, reducing the impact and wear of sand and gravel on the flexible baffle 11. The flexible baffle 11 is used to suppress the splashing of dust and mud. The flexible protective layer 14 can effectively reduce the noise generated by sand and gravel hitting the mesh plate 6. By dividing the blocking structure of the mudguard into two parts, the splash prevention capability of the mudguard is effectively improved, and its durability and applicability are enhanced.

[0015] The flexible baffle 11 is provided with a flow guide hole 15, and a baffle mechanism is provided on the outside of the flow guide hole 15. The flow guide hole 15 includes an upper first flow guide hole portion 16 and a lower second flow guide hole portion 17. A partition 18 is provided between the first flow guide hole portion 16 and the second flow guide hole portion 17. The diameter of the second flow guide hole portion 17 is larger than the diameter of the first flow guide hole portion 16. The baffle mechanism includes a first baffle 19 and a second baffle 20. The top end of the first baffle 19 is connected above the first guide hole 16 via a torsion spring 21, and the bottom end of the second baffle 20 is connected below the second guide hole 17 via a torsion spring 21. The second baffle 20 is located inside the first baffle 19. A groove 15 is provided on the inner side of the bottom edge of the first baffle 19, and a flexible limiting block 22 is provided on the bottom edge of the second baffle 20, which slides in contact with the inner side of the groove 15. When the flexible limiting block 22 moves to the groove 15, the groove 15 restricts the flexible limiting block 22 from continuing to slide, so as to prevent the second baffle 20 from separating from the first baffle 19. A wire mesh portion 23 is provided on the top of the first baffle 19, and a through hole 24 is provided on the bottom of the second baffle 20. In order to improve the aerodynamic performance of the flexible baffle 11, the conventional approach is to make holes in the flexible baffle 11 and set openable and closable baffles to optimize the airflow path. However, this method results in a significant decrease in aerodynamic performance due to the accumulation of slurry at the openings and on the baffle surfaces over time. To address this issue, this invention optimizes the flow guide hole and baffle structure. Airflow exits from the flow guide hole 15, flows inside the baffle mechanism, and then exits from both sides of the baffle mechanism. The second flow guide hole 17 pushes the second baffle 20 with a relatively large flow rate. Simultaneously, the second baffle 20 rotates, pushing the first baffle 19 to rotate, thereby adjusting the volume of the airflow buffer space in the direction of the flow guide hole outlet to accommodate different flow rates. After exiting from the second flow guide hole 17, guided by the second baffle 20 and the first baffle 19, most of the airflow flows upwards along the baffles, mixing and agitating with the airflow exiting from the first flow guide hole 16 at the wire mesh section 23. The wire mesh section 23 filters and collects the slurry carried in the airflow. The accumulated slurry drips down by gravity and is eventually discharged from the through hole 24. By creating a high-speed circulating flow of air inside the baffle mechanism, mud is less likely to adhere to the guide hole 15 and the baffle mechanism. Even if a small amount of mud adheres, since the present invention achieves adaptive adjustment of airflow velocity by changing the volume of the airflow buffer space, a small amount of mud will not have a significant impact on aerodynamic performance.

[0016] In addition, the inner side of the second baffle 20 is provided with an arc-shaped surface 25, and the airflow can be more smoothly mixed with the airflow flowing out from the first guide hole 16 at the wire mesh section 23 through the guide of the arc-shaped surface 25.
