Rainfall test system

Abstract

The invention discloses a rainfall test system comprising a rainfall room and a blow-dry room which is connected with the rainfall room. A blow-dry system is arranged in the blow-dry room. A spraying system and an image photographing and monitoring system are arranged in the rainfall room. A water recycling tank is arranged at the bottom part of the rainfall room. The rainfall test system also comprises a spray head installing plate. The spray head installing plate is installed in the rainfall room through a linear driving mechanism. The spraying system comprises spray heads which are connected with the water recycling tank through water ducts. The spray heads are fixed on the rainfall room installing plate. First water pumps and filters are arranged on the water ducts. The rainfall test system also comprises flow control mechanisms which are installed on the water ducts. A rainfall calibration system is arranged at the bottom part of the rainfall room. According to the rainfall test system, the rainfall capacity and the distance between the spray heads and an automobile to be tested can be controlled through the flow control mechanisms so that accurate simulation of light rain, moderate rain and heavy rain and other natural environments can be realized, and thus detection of the automobile sealing performance can be realized.

Description

technical field [0001] The invention relates to a vehicle rain test technology, in particular to a rain test system. Background technique [0002] During the use of automobiles, its airtightness is often one of the factors that customers are most concerned about. Water seepage or water ingress in vehicles will bring economic losses to customers, and it will also make customers feel insecure. The rain tightness test is an indispensable and important link. The currently used sealing test method is to set up a rain shower room. There is a sprinkler head on the top of the rain shower room. The vehicle enters under the sprinkler head to spray water. After drying the surface of the car body in the rain room, open the door and manually check whether there is water seepage in the car, but this method cannot control parameters such as the flow rate of the rain, the distance from the car body, etc., so that the airtightness of the car body cannot be accurately detected .
