Rear apron board assembly and automobile

Abstract

The invention relates to a rear apron board assembly and an automobile, the rear apron board assembly is provided with a rear apron board seam allowance edge used for installing a back door sealing strip, and the rear apron board seam allowance edge is provided with concave ribs which are concave towards the interior of the automobile. A space defined by the inwards-concave ribs is used for forming a drainage channel for draining water in the direction outside a vehicle between the seam allowance edge of the rear apron board and the back door sealing strip, and water leakage holes connected with the lower ends of the inwards-concave ribs are formed in the rear apron board assembly. The water leakage holes are formed in the portion, closer to the interior of the automobile than the rear apron board seam allowance edge, of the rear apron board assembly. The problems that at present, automobile rainwater is gathered in a cavity in the lower portion of the back door sealing strip and cannot be discharged in time, and the water discharge amount of the added outer convex ribs is possibly insufficient can be solved, and the waterproof performance of the back door sealing seam allowance edge area is improved; meanwhile, the problem that at present, a small amount of water enters an automobile and accumulates in a groove of the inner plate of the rear apron board and cannot be detected can be relieved or eliminated, and the water inlet detection function can be enhanced.

Description

technical field [0001] The invention relates to automobiles, in particular to a rear apron assembly and the automobile. Background technique [0002] The back door sealing strip of the car is an important part of the back door sealing system. The back door sealing strip is clamped on the sealing edge of the back door. The sealing edge of the back door is composed of the top cover, the side wall assembly and the rear skirt assembly. The top cover is located at the highest point of the sealing seam area of ​​the back door, and the rear skirt assembly is located at the lowest point of the sealing seam area of ​​the back door; the overlap between the top cover and the side wall assembly and At the lap joint of the inner sheet metal of the side wall assembly, the lip of the back door sealing strip forms a gap with the sheet metal. When rainwater flows through, it can enter the back door sealing strip; under the action of gravity, the rainwater flows along the back door sealing st...

AI Technical Summary

Problems solved by technology

In the prior art, there is an outer rib that protrudes toward the outside of the car on the side of the back door seal, and the lip edge of the back door sealing strip is opened to form a drainage gap, which is small; at the same time, the outer rib will be reduced or even closed. The cavity formed by the lip of the back door sealing strip and the sheet metal prevents water from flowing to the middle and lower parts; It will accumulate, and the water level may rise and enter the car over the sealing edge of the back door

At the same time, the sealing seam of the back door is inclined upward, and the inner panel of the rear skirt forms a groove structure at the root of the seam, where a small amount of water has accumulated in the rain line detection, but it cannot be found because of the covering of the interior parts; the vehicle In case of continuous rainy weather during use, a large amount of water will enter the car, which will cause problems such as water immersion and dampness in the car.
