Waterproof and drainage blanking cap for automobile

Abstract

The invention relates to a waterproof and drainage blanking cap for an automobile. The blanking cap comprises an outer threshold, an inner threshold, a cavity, a side wall outer plate and a B column reinforcing plate, wherein an exterior trim mounting through hole is formed in the outer side of the outer threshold, the inner threshold is connected with the outer threshold, the cavity is defined by the outer threshold and the inner threshold, and the B column reinforcing plate is connected with the side wall outer plate and the outer threshold. The blanking cap further comprises a drainage hole which is formed in the lower end of the inner threshold and communicated with the cavity, and a drainage waterproof blanking cap provided with a silencing assembly. According to the waterproof and drainage blanking cap for the automobile, water leaking into the cavity can be drained in time, the automobile thresholds are not prone to being corroded by accumulated water, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle bodies, in particular to a blocking cover for automobiles which takes into account both waterproofing and drainage. Background technique [0002] The structure of the side wall outer panel, B-pillar reinforcement plate, inner sill and outer sill of the car can be understood from the structure of the outer sill corner plate at the lower end of the B-pillar disclosed in the invention of Chinese patent application number 202010635392.4; the traditional car sill is set by the relative The outer sill and the inner sill are connected, and a cavity is formed between the outer sill and the inner sill. There are exterior decoration installation through holes on the outside of the outer sill, and the B-pillar reinforcement plate is connected to the side wall outer panel and the outer sill respectively; the traditional car sill There is a problem that the water leaking into the cavity from the ins...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the disadvantages of the current automobile threshold that the water leaking into the cavity from the exterior installation through hole, the connection between the outer threshold and the inner threshold is not easy to be discharged in time, and the automobile threshold is easy to accumulate water and corrode and shorten the service life. The water leaking into the cavity can be discharged in time, and the car door sill is not easy to be corroded by water, and the service life is extended, which is waterproof and draining.
