Problems solved by technology

The disadvantage of this structure is that after rainwater enters the luggage compartment, it can only flow along the inner cavity of the rear wall to the rear floor, forming accumulated water
When the car is driving on a rainy day or undergoing a rain test, the rainwater is easy to deposit on the sealing strip around the trunk (or back door) door opening. When it accumulates to a certain extent, the rainwater will enter the luggage compartment through the sealing strip and finally collect in the Water accumulated on the rear floor or in the spare tire well will cause sheet metal to rust and interior parts to mold, causing trouble to customers

Abstract

The invention relates to an automobile rear wall structure, in particular to a rear wall structure with a drainage function. The rear wall structure comprises a rear base plate, a rear wall outer plate and a rear wall inner plate. The lower end of the rear wall inner plate downwards extends to be in lap joint with the rear end of the rear base plate. The rear wall outer plate comprises a vertical flanging in lap joint with the rear end face of the rear wall inner plate, and a connecting plate which is fixed to the upper end of the flanging and backwards extends. Drainage grooves allowing rainwater to pass through are formed between the flanging and the rear wall inner plate and are through hole structures which are arranged in the Z direction and located on one side of the rear end face of the rear wall inner plate. The rear base plate and the drainage grooves are separately arranged on and formed in the front side and the rear side of the rear wall inner plate and do not overlap in the vertical direction. The rear wall structure is simple, water accumulation of the rear base plate is avoided by forming the drainage grooves in the outer side of the rear base plate, the liquid discharge efficiency is improved by arranging an electrophoretic liquid discharge structure, the airtightness of an automobile cannot be affected after blocking is conducted, and the rear wall structure is convenient to mount and has great popularization value.

Description

technical field [0001] The invention relates to an automobile rear wall structure, in particular to a rear wall structure with drainage function. Background technique [0002] The rear wall structure of the current automobile is formed by overlapping the rear wall outer panel and the rear wall inner panel. In order to facilitate the flow of electrophoretic fluid, a gap is provided at the overlap between the rear wall outer panel and the rear wall inner panel. figure 1 As shown, the traditional back wall structure includes the existing outer panel and the existing inner panel, the lower part of the existing outer panel is overlapped with the existing rear floor to form a sealing surface, the lower part of the existing inner panel is overlapped with the middle part of the existing outer panel, Drainage grooves are arranged on the lap joints. The disadvantage of this structure is that after rainwater enters the luggage compartment, it can only flow along the inner cavity of th...
