Shower testing system and method for cars

Abstract

A system used for testing car-wetting by rain comprises closed test space, water supply unit, spraying unit, heating unit and safety unit. It is featured as forming said spraying unit by water pump, pressure regulation element, multiple sub-spray pipe and position regulation component for spraying water on car as per set parameter; forming said heating unit by multiple lamp tube and temperature control element for heating test space; forming water supply unit by two water storage pools as one being used to supply water to said spraying unit and another being used to collect waste water from test space.

Description

technical field [0001] The invention relates to testing, in particular to an automobile rain testing system and method. Background technique [0002] During the use of automobiles, the airtightness of the entire vehicle is often one of the factors that customers are most concerned about. Water seepage or even water ingress in the vehicle will bring certain economic losses to customers and make customers feel unsafe. The car rain test is a test method for testing the sealing performance of the whole car. It mainly evaluates the ability of the car to prevent water from entering the passenger compartment and trunk when the door, window and hole cover are closed in rainy days and car wash environments. It is a key test item in the rainy state, and the aging speed of automotive sealing equipment will be accelerated under changing environmental conditions. [0003] At present, domestic automobile rain tests mainly include moderate rain test, May rain test, salt spray corrosion te...

AI Technical Summary

Problems solved by technology

[0004] 1. The construction cost of the test laboratory is high, the floor area is large, and the test cost and maintenance cost are expensive;

[0005] 2. Even if the performance of the seal is tested separately, it cannot fully reflect the actual use condition after aging;

[0006] 3. It is not possible to carry out comprehensive tests for different climatic conditions

[0007] Therefore, the cost of the existing technology is high, and the comprehensive testing ability is not strong
