Rain test device for extremely-cold-resistant energy-saving vehicle window

Abstract

A rain test device for an extremely-cold-resistant energy-saving vehicle window comprises a test framework (1), a water spray device(2), an installing plate (3) and a timer (4), wherein a water tank (5) is arranged in the bottom of the test framework (1), the water spray device(2) is fixedly installed on the test framework (1), a plurality of crimpers (6) are arranged on one side face of the test framework (1), the installing plate (3) is fixed on the side face of the test framework (1) through the crimpers (6), a water pump (7) is fixedly installed in the water tank (5), a water pipe (8) on the water pump (7) is connected with the water spray device(2) through a flow meter (9), and the flow meter (9) is fixed on the test framework (1). Test on vehicle windows of different sizes can be conducted, and the installation is fast and convenient. Water for rain test can be recycled for reuse to save water and ensure that a test work area is dry.

Description

technical field [0001] The invention relates to the field of performance testing of high-speed train components, in particular to a rain test device for high-cold energy-saving car windows. technical background [0002] With the continuous advancement of railway passenger car technology, the issue of passenger ride comfort has attracted more and more attention. The window is one of the important components of a railway passenger car. The window accounts for about one third of the area of ​​the side wall of the entire passenger compartment, so The performance of the window directly affects the comfort of the passenger compartment. [0003] my country has a vast territory, and some long-distance trains span many areas; the temperature difference between the north and the south is large, and the temperature difference between the inside and outside of the passenger car can reach 70°C in winter. A large area of ​​railway passenger cars operating in winter in the northern alpine...

AI Technical Summary

Problems solved by technology

A large area of ​​railway passenger cars operating in winter in the northern alpine region has exposed the problem of poor cold protection and heat insulation of the windows, resulting in high-cold energy-saving windows; According to the requirements of the rainproof performance test, it is necessary to test whether the rainproof performance of the product meets the standard requirements. Because the size of the window corresponding to different models is different, this brings a lot of inconvenience to the rainproof test, and it needs to rely on different test equipment Complete, high test cost
