Detection device for electric vehicle reinforced corrosion test

Abstract

The invention discloses a detection device for an electric vehicle reinforced corrosion test. The detection device comprises a light shield, a light source and a camera. The light source is arranged at the top in the light shield; a shading plate is arranged below the light source; the shading plate is provided with a light through hole; a sliding plate which is connected with the light shield inan up-and-down sliding manner is arranged below the light through hole; the sliding plate is provided with a convex lens, the camera is arranged below the convex lens, light emitted by the light source sequentially penetrates through the light through hole and the convex lens and then is projected to the surface of the vehicle body, the surface of the vehicle body reflects the light into the camera to be collected, and the camera is in signal connection with the display device. According to the detection device for the electric vehicle reinforced corrosion test, the same area of the vehicle body is only subjected to light emitted by one light-emitting point so that the light and shade difference between the scratch position and the non-scratch position of the vehicle body is obvious.

Description

technical field [0001] The invention relates to the technical field of corrosion testing of electric vehicles, in particular to a detection device for enhanced corrosion testing of electric vehicles. Background technique [0002] The enhanced corrosion test for automobiles refers to the tests in which the automobiles are carried out in the proving ground with working conditions such as driving on gravel roads, driving on salt water roads, salt spray spraying, and parking in environmental chambers. The test conditions are mainly simulated: driving on non-paved roads, driving on roads sprayed with deicing agent, marine climate and hot and humid climate. In the test stage, one test cycle experienced 9 test conditions. Among them, the enhanced corrosion comprehensive road driving conditions include gravel road driving, salt water washboard road driving, salt water tank road driving, etc. One test cycle is 24 hours, and 10 test cycles simulate the actual use of the vehicle for ...

Problems solved by technology

If a light source is used for irradiation, only one position of the car body is reflected to the observation position in the form of specular reflection or close to specular reflection, and only one position of the car body scratches can be observed at a time, and the observation efficiency is low; if multiple light sources are used from Irradiation from different angles, although multiple positions on the body reflect to the observation position in the form of mirror reflection or near-mirror reflection, but at the same time, the same body position is irradiated by light-emitting points from multiple angles, and the light interferes with each other, resulting in scratches on the body The light and dark difference between the position and the non-scratched position is not obvious, and it is not easy to observe the scratches on the car body
