Abstract

The invention relates to a waterproof testing device comprising a test box, a water spraying device and a water return device. The water spraying device includes nozzles arranged in the test box. Thewater return device is respectively connected to the bottom of the test box and the nozzles through water pipes. Regulating valves are arranged at water pipes between the water return device and the nozzles. The water spraying device further includes an adjusting rod assembly connecting the nozzles. The adjusting rod assembly includes a horizontal rod, a lifting rod assembly with the adjustable bottom and height, and a nozzle adjusting rod; the horizontal rod is horizontally disposed at the top of the test box; the lifting rod assembly is vertically connected to the horizontal rod; the nozzleadjusting rod is horizontally disposed at the bottom of the lifting rod assembly; and no less than two nozzles are arranged at the nozzle adjusting rod and can change the positions in an axial direction of the nozzle adjusting rod. Compared with the prior art, the testing device has the following advantages: sprayed water can cover the surface of the whole sample; the application range is wide; and the test cost is lowered.

Description

technical field [0001] The invention relates to the field of reliability testing, in particular to a waterproof testing device. Background technique [0002] In the actual driving conditions of the car, the electronic module in the concealed part of the car is vulnerable to corrosion caused by internal human factors and unpredictable factors outside the car, such as coffee, glass water, and interior cleaners. It is necessary to simulate this corrosion state to test the electronic module. For the waterproof performance of the module, the waterproof test device can be used to spray water on the electronic module at a certain angle, pressure, and flow rate to test the anti-corrosion ability of the electronic module to various liquids. Most of the existing waterproof test devices use multiple fixed nozzles. The distance between the sample and the nozzles is changed by lifting the loading platform, and the position of the nozzles cannot be adjusted according to the coverage of di...
