Automobile rain test bench

Abstract

The invention discloses an automobile rain test bench which comprises a test bench body used for bearing an automobile, wherein a spraying area is formed at the top of the test bench body; a rain direction adjusting mechanism which is installed in the spraying area, and comprises an adjusting plate, a plurality of nozzles and a plurality of adjusting assemblies, wherein the output ends of the adjusting assemblies are correspondingly connected with themultiple positions of theadjusting plate; a rainfall adjusting mechanism which comprises a water storage tank, a water conveying pipe, a liquid level meter and an electromagnetic valve, wherein the water storage tank is used for supplying water to the multiple nozzles, the liquid level meter is installed in the water storage tank to measure the water level, the two ends of the water conveying pipe are communicated with the nozzles and the water storage tank respectively, and the electromagnetic valve is installed on the water conveying pipe; and a controller which is electrically connected with the liquid level meter, the electromagnetic valve and the multiple groups of adjusting assemblies. According to the automobile rain test bench, rain test elements such as the rain time and the rain direction of each automobile are consistent, so that the rainy environment is accurately simulated, and the rain test result is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to an automobile rain test stand. Background technique [0002] With the advancement of automobile technology, the airtightness of the whole vehicle has become a problem that drivers and passengers are very concerned about. The airtightness of the car is not only directly related to the life safety of the driver and passengers, but also related to the quiet environment inside the car. Being able to safely drive or ride in a car with good airtightness without interference is a direct consideration of the safety and comfort of the car. Therefore, in the automobile manufacturing process, the rain test will be carried out to simulate the normal operation of the automobile in rainy weather to test the airtightness of the automobile. [0003] The traditional automobile rain test bench is generally equipped with a nozzle on the spray frame. The announcement number CN206683863U di...

AI Technical Summary

Problems solved by technology

[0003] The traditional automobile rain test bench is generally equipped with a nozzle on the spray frame. The announcement number CN206683863U discloses a vehicle rain test bench. Since the rain direction of the spray frame is fixed, even if the rain test bench can be rotated, the vehicle spray can be changed. The direction of rainwater spraying, but the angle of rainwater spraying cannot be changed, so that the test car does not get all-round spraying, and the length of the car's raining time is completely controlled by the staff, which cannot be done for each car's raining time. Consistency, thus unable to accurately simulate the rainy environment, resulting in inaccurate results of the rain test
