Motor vehicle real vehicle wiper test system and test method

Abstract

The invention discloses a motor vehicle real vehicle wiper test system and a test method. The system comprises a spraying room. The spraying room is provided with a transportation frame for placing a motor vehicle; the bottom of the transportation frame is provided with a conveying mechanism for driving the transportation frame to transport to the inside of the spraying room; a bracket is fixed on the transportation frame; the bracket is fixed to an infrared sensor and a first resistance cylinder, wherein the infrared sensor and the first resistance cylinder face towards a windshield glass of the motor vehicle; a wiper floating rule on the windshield glass passes the infrared sensor and the first resistance cylinder in the process of movement sequentially. The motor vehicle wiper test system and the test method can measure the scraping frequency, automatic return, resistance braking, durability and other aspects of the wiper on the real vehicle, thus the measurement performance is integrated, and the measurement accuracy is high; the nozzle in the spraying room is controllable in water amount and distance, can simulate heavy rain, light rain and other environments so that the wiper can be tested in different environments, and the test accuracy is improved.

Description

technical field [0001] The invention relates to a wiper test device, in particular to a real vehicle wiper test system and test method. Background technique [0002] Wipers, also known as wipers, water dials, wipers or windshield wipers, are devices used to wipe off raindrops and dust attached to the windshield of vehicles to improve the visibility of drivers and increase driving safety. After the wiper is produced, it needs to be tested for various functions to ensure its normal use on the car. At present, when the wiper is tested, the durability test of the wiper is usually only carried out under simulated environmental conditions. [0003] As Chinese patent 201220194608.9 discloses a test device for automobile wipers, it mainly includes a test bench, a windshield is fixed on the test bench, a wiper is arranged at the windshield, and the wiper and a driving The wiper is connected to the control mechanism that swings back and forth on the windshield; the test bench is also...

[0003] As Chinese patent 201220194608.9 discloses a test device for automobile wipers, it mainly includes a test bench, a windshield is fixed on the test bench, a wiper is arranged at the windshield, and the wiper and a driving The wiper is connected to the control mechanism that swings back and forth on the windshield; the test bench is also provided with a frosting mechanism that can produce frost on the windshield. The wiper test device has the ability to better simulate the real environment. It is better to evaluate the defrosting effect of the wiper, but this kind of test bench does not have the test of the wiping frequency of the wiper, the return angle of the wiper rod, etc., so the test is not comprehensive, and it is impossible to make a complete evaluation of the overall performance of the wiper
