Wherein the height of the characteristic rib is 1.5mm-2.0 mm.
Wherein the characteristic ribs are square convex ribs.
Compared with the prior art, the utility model discloses a rear wheel casing with exhaust muscle structure has following beneficial effect:
1. the characteristic rib structure is added on the rear wheel cover inner plate or the rear wheel cover outer plate, and no working procedure is added in the stamping process;
2. the rear wheel cover inner plate or the rear wheel cover outer plate is added with a characteristic rib structure, so that gas is quickly discharged when electrophoresis is carried out on the tank, the problem of a gas chamber is solved, and the electrophoresis quality is improved;
3. the subsequent coating and frictioning can be completely sealed, and the problems of poor sealing and corrosion are avoided.

Detailed Description
The following will be described in detail with reference to the specific embodiments of the present invention, so as to help those skilled in the art to understand the technical solution of the present invention more completely, accurately and deeply.
Example 1
As shown in fig. 3-8, the rear wheel casing with the air exhausting rib structure of the embodiment includes a rear wheel casing inner plate 10 and a rear wheel casing outer plate metal plate 20, the rear wheel casing inner plate 10 includes an inner plate body 11 and an inner plate connecting section 12 formed by bending the upper end of the inner plate body 11, the rear wheel casing outer plate metal plate 20 includes an outer plate metal plate body 21 and an outer plate metal plate connecting section 22 formed by bending the upper end of the outer plate metal plate body 21, and the length of the inner plate connecting section 12 is greater than that of the outer plate metal plate connecting section 22. Be formed with inside cavity 30 between inner panel body 11 and the planking panel beating body 21, and be formed with interval arrangement's characteristic muscle on inner panel linkage segment 12 or planking panel beating linkage segment 22 internal surface that faces mutually, what figure 5 shows is the characteristic muscle 13 that forms at the internal surface of inner panel linkage segment 12, what figure 8 shows is the characteristic muscle 23 that forms at the internal surface of planking linkage segment 22, inner panel linkage segment 12 and planking panel beating linkage segment 22 welded fastening, thereby form the intercommunication between the characteristic muscle of interval arrangement the gas passage of inside cavity 30. The height of the characteristic rib is not particularly limited, but in order to meet the requirement of the electrophoresis process exhaust, the height of the characteristic rib is preferably 1.5mm to 2.0mm, and the characteristic rib is preferably a square rib, and the characteristic rib extends along the length direction of the inner panel connecting section 12 or the outer panel metal connecting section 22 (the direction shown by the parallel line in fig. 5 or fig. 8).
In the electrophoresis process of the body-in-white, as shown in fig. 9, the groove is inclined at an angle of 45 degrees, the rear wheel cover area is in an inclined state, air in the inner area of the rear wheel cover cannot be quickly exhausted, and air chambers (as shown in fig. 9) are generated in the electrophoresis process, so that the quality of a paint film is influenced. And the back wheel casing of this embodiment consequently increases characteristic muscle structure at back wheel casing inner panel or back wheel casing planking panel beating, and the clearance between the accessible characteristic muscle is rapidly with wheel casing inner space gas outgoing in the groove stage of entering, avoids producing the air chamber, guarantees the electrophoresis lacquer membrane quality, and follow-up application frictioning can be sealed completely moreover, does not have sealed bad automobile body corrosion resistance that promotes, and the technical scheme of this embodiment has been through on-the-spot verification, and the electrophoresis is respond well.
For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements are all within the protection scope of the present invention as long as the technical solution of the present invention is adopted.
