Problems solved by technology

[0002] The car door sheet metal is composed of the inner panel and the outer panel of the door. The middle of the inner panel and the outer panel is the door glass. In rainy days or when the car is washed, water will flow into the door panel wall along the gap of the glass. Fluid will corrode the door sheet metal, so it is necessary to open a drain to drain the water, but the opening on the door sheet metal will affect the sealing type and NVH performance of the car

Abstract

The invention discloses an automobile door drainage device. The automobile door drainage device is characterized by comprising an automobile door metal plate; a drainage hole is formed in the automobile door metal plate; a one-way valve blanking cap is arranged in the drainage hole and fixed to the portion, on the outer side of the drainage hole, of the automobile door metal plate through at least two clamping mechanisms. Each clamping mechanism comprises a first clamping head and a second clamping head, wherein the first clamping head and the second clamping head form a clamping groove. When the one-way valve blanking cap is clamped with the automobile door metal plate, the side edge of the drainage hole is clamped into the clamping grooves. The automobile door drainage device has the remarkable effects that the structure is simple and practical, when no liquid flows through, the blanking cap achieves the sealing effect, and the influences on the NVH performance of an automobile are avoided; when liquid flows through, the liquid flows out of the automobile door metal plate, the liquid is drained, it is guaranteed that no liquid is accumulated in the automobile door metal plate, and corrosion of the accumulated liquid to the automobile door metal plate is avoided.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an auto door liquid draining device. Background technique [0002] The car door sheet metal is composed of the inner panel and the outer panel of the door. The middle of the inner panel and the outer panel is the door glass. In rainy days or when the car is washed, water will flow into the door panel wall along the gap of the glass. The effusion will corrode the door sheet metal, so it is necessary to open a drain to drain the water, but the opening on the door sheet metal will affect the sealing type and NVH performance of the car. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a liquid discharge device for an automobile door, which can not only play a sealing role, but also discharge liquid in one direction, so as to ensure the NVH performance of the vehicle. [0004] In order to achieve ...
