Detailed Description

The utility model will be further explained with reference to the drawings.

As shown in fig. 1 to 8, in the present embodiment, an ash filtration mud guard includes an ash filtration mud guard upper cover 1 and an ash filtration mud guard lower cover 2, the ash filtration mud guard upper cover 1 and the ash filtration mud guard lower cover 2 are fastened to form an accommodating space for accommodating an ash filter 41, and the ash filtration mud guard upper cover 1 and the ash filtration mud guard lower cover 2 are fixedly connected together by a first bolt 3 and a first nut 22; the top of the upper cover 1 of the ash filtering mud guard is provided with a mounting hole 13 used for being connected with an ash filtering bracket 42.

As shown in fig. 5, in the present embodiment, the upper cover 1 of the ash filtering mud guard is a plastic member, and includes an upper cover body and a rib 11 disposed at an opening of the upper cover body.

As shown in fig. 6 to 8, in the embodiment, the lower cover 2 of the ash filtering mud guard is a plastic member, and includes a lower cover body and a concave rib 23 disposed at an opening of the lower cover body, wherein the concave rib 23 is correspondingly matched with the convex rib 11.

As shown in fig. 7, in this embodiment, a boss circular hole 12 is further formed on the mouth of the upper cover body. The mouth of the lower cover body is also provided with a nut seat 21 corresponding to the boss round hole 12. The first nut 22 is embedded in the nut seat 21. The first nut 22 is assembled to the nut seat 21 by extrusion after the injection molding of the lower cover 2 of the ash filter mud guard. The magnitude of interference between the nut holder 21 and the first nut 22 is adjusted to adjust the removal force of the first nut 22, thereby preventing the first nut 22 from being removed.

In the embodiment, as shown in fig. 9, the ash filter bracket 42 is a metal stamping, and the ash filter bracket 42 is welded to the filler pipe 4.

As shown in fig. 10, during installation, the second bolt 6 is used to fix the mounting hole 13 on the upper cover 1 of the ash filtering mud guard with the second nut 421 in the ash filtering bracket 42, and then the lower cover 2 of the ash filtering mud guard is buckled with the upper cover 1 of the ash filtering mud guard through the convex rib 11 and the concave rib 23. The lower cover 2 of the ash filtering mud guard and the upper cover 1 of the ash filtering mud guard are fixedly connected together by two first bolts 3. After the installation, the ash filter 41 is located in the containing space of the ash filter mud guard.

As shown in fig. 11, the dust filter mud flap is fixed below the nozzle of the filler pipe 4 and above the tire 7 by the second bolt 6 through the dust filter bracket 42. The ash filter mud guard separates the ash filter 41 from the tire 7, so that muddy water splashed by the tire 7 cannot enter the canister stop valve 8 through the ash filter 41.

As shown in fig. 10, in the present embodiment, the ash filter mud guard is tightly engaged with the convex rib 11 and the concave rib 23 to shield the ash filter 41, so that muddy water splashed by the tire 7 can be effectively prevented from entering the canister stop valve 8 through the ash filter 41. Compared with the existing mode of increasing the wheel cover 5, the ash filtering mud guard has great cost advantage due to small parts. When the ash filter 41 is repaired and replaced, the ash filter 41 can be replaced only by disassembling the first bolt 3 and the second bolt 6, so that the ash filter has the advantages of convenience in maintenance and good repeated maintainability.
