Spraying device, spraying control method and windscreen wiper testing system

Abstract

The invention belongs to the technical field of automobile part production and manufacturing, and discloses a spraying device, a spraying control method and a windscreen wiper testing system. The spraying device comprises the following mechanisms of: a liquid supply mechanism which is arranged in an automobile and used for providing spraying liquid; a detection mechanism which is arranged on the inner side of a windshield of the automobile and used for detecting the amount of spraying liquid on the windshield; and a spraying mechanism which is arranged on an engine hood of the automobile, is communicated with the liquid supply mechanism, adjusts the angle and the spraying amount of spraying liquid sprayed to the windshield according to the amount of the spraying liquid on the windshield. The angle and spraying amount of the spraying liquid of the spraying device are adjustable, automatic adjustment of the spraying amount and the spraying angle can be achieved, the sufficiency and uniformity of the water spraying amount can be achieved without manual adjustment, operation is easy, the test progress is not affected, and the test efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobile parts production and manufacturing, in particular to a spray device, a spray control method and a wiper test system. Background technique [0002] With the rapid development of China's economy, people have put forward higher requirements for vehicle safety. When the car is driving at high speed in rainy days, it is particularly important to keep the vision clear. In order to ensure the function of the wiper during the high-speed driving of the car, it is often necessary to test the high-speed performance of the wiper after the production is completed, so as to ensure that the wiper can also operate normally when the wind speed reaches 80% of the maximum speed of the car. Thereby ensuring driving vision and safety. [0003] The wiper test is generally achieved through wind tunnel experiments, which require a large amount of water spray to test the performance indicators of the wiper. Existing...

Problems solved by technology

[0004] First, the washing system that comes with the car is used. However, due to the complicated process of the wind tunnel experiment, there are many test items, and the time is long. The squeegee blade will be dry-scratched during operation, which will wear the rubber strip of the squeegee blade. The test time is long and the test effect is poor;

[0005] Second, using a test bench, the water spray volume of the existing test bench is uneven, which affects the judgment of the high-speed performance of the wiper

At the same time, according to the experience of the experimenters, the direction of spraying water is arranged. When the wind speed is high, the amount of sprayed water will often be affected by the wind speed. As the wind speed increases, appropriate adjustments must be made every time, and the operation is cumbersome
