Detailed Description
Referring to fig. 1-3, a specific embodiment of the invention comprises a base plate 1 and a screen plate 6, wherein a plurality of mounting holes 2 for fixing with a vehicle body are formed in the base plate 1, a slot 3 is formed in the bottom edge of the base plate 1, limit bars 4 are arranged on two sides of the bottom of the slot 3, through grooves 5 are formed in the side walls of the slot 3, cutting bars 7 which are in plug-in fit with the slot 3 are arranged on the top of the screen plate 6, the cutting bars 7 are plugged in the slot 3 and limit through the limit bars 4, a hollow cylinder 8 is arranged on one side, facing away from a vehicle wheel, of the screen plate 6, an opening 9 is formed in the side wall of the hollow cylinder 8, a connecting shaft 10 is mounted in the hollow cylinder 8, a flexible baffle 11 is connected to the connecting shaft 10, a plurality of positioning holes 12 are formed in one end, facing the outer side of the vehicle wheel, of the hollow cylinder 8, and a threaded hole (not shown in the figure) is formed in the connecting shaft 10, and the adjustment of the mounting angle of the flexible baffle 11 is realized by aligning the threaded holes with the different positioning holes 12 and locking by using bolts 13. The side of the mesh plate 6 facing the wheel is detachably provided with a flexible protective layer 14. In use, a proper type of base plate 1 is selected according to the vehicle body structure, and the base plate 1 is fixed on the vehicle body through the mounting holes 2. The net plate 6 is then inserted into the slot 3 and secured by screws through the through slots 5. Then, the flexible baffle 11 is adjusted according to the running road condition (when the running speed is lower or the road surface is cleaner, the initial angle of the flexible baffle 11 is reduced, otherwise, the initial angle of the flexible baffle 11 is increased, so that the flexible baffle 11 is at the optimal initial angle, and the connecting shaft 10 is fixed by using the bolts 13. The screen 6 is used for blocking sand and reducing impact and abrasion of the sand and the flexible baffle 11, and the flexible baffle 11 is used for inhibiting splashing of dust and muddy water. The flexible protective layer 14 is effective to reduce noise generated by sand striking the screen 6. By dividing the blocking structure of the mud guard into two parts, the splash-proof capacity of the mud guard is effectively improved, and the durability and the application range are improved.
The flexible baffle 11 is provided with a diversion hole 15, and a baffle mechanism is arranged outside the diversion hole 15. The deflector hole 15 includes a first deflector hole portion 16 above and a second deflector hole portion 17 below, a partition 18 is provided between the first deflector hole portion 16 and the second deflector hole portion 17, and the diameter of the second deflector hole portion 17 is larger than that of the first deflector hole portion 16. The separation blade mechanism includes first separation blade 19 and second separation blade 20, the top of first separation blade 19 passes through torsional spring 21 to be connected in first water conservancy diversion hole portion 16 top, the bottom of second separation blade 20 passes through torsional spring 21 to be connected in second water conservancy diversion hole portion 17 below, second separation blade 20 is located the inboard of first separation blade 19, first separation blade 19 base inboard is provided with draw-in groove 15, the base of second separation blade 20 is provided with the flexible stopper 22 with draw-in groove 15 inboard sliding contact, when flexible stopper 22 moves to draw-in groove 15, draw-in groove 15 restriction flexible stopper 22 continues to slide, in order to avoid second separation blade 20 and first separation blade 19 to break away from each other, first separation blade 19 top is provided with silk screen portion 23, second separation blade 20 bottom is provided with through-hole 24. In order to improve the aerodynamic performance of the flexible barrier 11, conventionally, holes are formed in the flexible barrier 11, and a shutter that can be opened and closed is provided to optimize the airflow path. However, this approach can cause significant degradation in aerodynamic performance due to the large amount of mud adhering to the openings and to the surface of the baffle over time. The present invention addresses this problem by optimizing the flow guiding hole structure and the baffle structure such that the air flows inside the baffle mechanism after exiting the flow guiding hole 15, and then exits from both sides of the baffle mechanism. The second deflector hole 17 pushes the second baffle 20 through relatively large-flow air flow, and the second baffle 20 pushes the first baffle 19 to rotate while the second baffle 20 rotates, so that the volume of the air flow buffer space in the outlet direction of the deflector hole is adjusted, and the air flow buffer device is suitable for air flows with different flow rates. After the air flow flows out of the second diversion hole part 17, most of the air flow flows upwards along the baffle plates under the diversion of the second baffle plates 20 and the first baffle plates 19, and is mixed and stirred with the air flow flowing out of the first diversion hole part 16 at the silk screen part 23, the silk screen part 23 filters and collects mud carried in the air flow, and the collected mud drops by gravity and finally is discharged from the through holes 24. By enabling the air flow to form high-speed circulating flow inside the baffle plate mechanism, mud is not easy to adhere to the flow guide holes 15 and the baffle plate mechanism, and even if a small amount of mud is adhered, the self-adaptive adjustment of the air flow speed is realized through the change of the volume of the air flow buffering space, so that the pneumatic performance is not obviously influenced by the small amount of adhered mud.
In addition, the inner side surface of the second baffle 20 is provided with the arc surface 25, and the air flow guided by the arc surface 25 can be more smoothly mixed with the air flow flowing out of the first guide hole part 16 at the wire mesh part 23.
