Rain room for air-tightness detection system

Abstract

The invention discloses a rain room for an air-tightness detection system. The rain room comprises a rain room body. A spray system is arranged inside the rain room body. A return water pool is arranged at the bottom of the rain room body. The rain room further comprises a spray head mounting plate which is mounted inside the rain room body through a linear drive mechanism. The spray system includes a spray head which is connected to the return water pool through a water delivery pipe. The spray head is fixed on a rain room body mounting plate. A first water pump and a filter are arranged on the water delivery pipe. The rain room further comprises a flow control mechanism mounted on the water delivery pipe. According to the rain room for an air-tightness detection system of the invention, the rainfall and the distance between the spray head and a vehicle to be detected can be controlled by the flow control mechanism, natural environments such as light rain, moderate rain and heavy rain can be simulated accurately, control is performed through a control system, and artificial adjustment is reduced.

Description

technical field [0001] The invention relates to a vehicle rain test technology, in particular to a rain room used for an airtightness detection 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 body. There is a sprinkler head on the top of the rain shower room body, and the vehicle enters under the sprinkler head to spray water. However, this structure setting After the big car and the small car enter the shower room, the distance between the sprinkler head and the surface of the body is very different, so that after the vehicles of different specifications enter, the test environment and conditions will change...
