Embodiment Construction

[0010] The technical solution of the present invention will be described in further detail below according to the accompanying drawings.

[0011] Such as figure 1 Shown is the entire wiper durability test equipment assembly. The test is carried out in the wiper workshop, and the test equipment includes the test sample, the control unit and the water circulation unit. The test sample is the latest wiper installation part, which is required to be installed on the prototype car or the body-in-white according to the product technical requirements, including 3 pairs of wiper blades. The outer surface of the windshield should be kept sufficiently clean and free from any oil and dirt.

[0012] The water circulation system disclosed by the present invention is as figure 2 As shown, the wiper durability test adopts the water pump to circulate water, and the water pump pumps the filtered clean water in the reservoir to the spray tank, and the sprayed water settles through the sedime...

Abstract

The invention discloses a water circulation system used for the endurance test of an automobile windscreen wiper; the wiper endurance test adopts a water pump for water supply; clean water which is filtrated in a reservoir is pumped to a spraying box by a water pump; the sprayed water is deposited by a sedimentation tank; and finally, the water flows back in the reservoir by a filter net, thus completing the circulation of water used for testing; and the water speed can be adjusted by a water pressure adjusting valve; the water speed is indicated by a flowmeter. The water circulation system disclosed by the invention achieves the water-saving object and ensures the cleanness and stability of the water used for testing, and simultaneously, the water flow speed adjustment is simple and convenient, and the test results are exact; the whole water circulation system has high efficiency, low cost, simple and convenient operation and strong adaptability.

Description

technical field [0001] The patent of the present invention belongs to the field of automobile electrical system, and specifically relates to a water circulation system used for durability test of automobile windshield wiper. Background technique [0002] Existing automobile windshield wiper suppliers can only use tap water to carry out the wiper durability test outdoors, and the test water is very wasteful. Affected by factors such as harsh environment (sunshine, high temperature, dust) and unstable water spray (wind force, water impurities), the durability of the wiper blade and motor will be significantly deteriorated, and the test results under this condition are also Inaccurate. Contents of the invention [0003] The present invention is aimed at the deficiencies in the prior art, proposes a kind of water circulation system that is used for the durability test of automobile windshield wiper, technical scheme of the present invention is as follows: [0004] A water ci...
