Description
Technical Field
[0001] The utility model belongs to the technical field of anti-fog testing equipment for vehicle lamps, and in particular relates to an anti-fog testing device for vehicle lamps. Background Art
[0002] The fog inside the car headlights is usually caused by poor sealing of the headlights or water vapor entering the headlights through the exhaust holes. Therefore, the anti-fog test of the headlights is an important measure to avoid the fog inside the headlights. When water enters the headlights, a large amount of heat is generated when the lamps are lit, which may produce water mist and not dissipate for a long time. If the water ingress is serious, a large amount of water droplets or water accumulation will form on the surface. The anti-fog test of the headlights is to test the waterproof and water-resistant performance of the headlights by simulating rainy days or humid environments. Through the anti-fog test of the headlights, the sealing performance of the car headlights can be tested to prevent the headlights from getting damp or water intruding, thereby avoiding the fog inside the headlights.
[0003] However, the existing anti-fog test device for automobile lamps usually uses a fixed spray device to spray the lamps. Since the lamp housing is designed to be arc-shaped, this will result in a limited contact range between the water mist and the lamp. At the same time, the fog inside the test box will also be unevenly distributed, which will affect the test results. Therefore, we propose an anti-fog test device for automobile lamps to solve the above problems. Utility Model Content

[0028] The test box 100 can store the fog in the anti-fog test and facilitate the installation of the spray assembly. The vehicle entrance 101 is conducive to sending the headlights on the vehicle into the test box 100 for the anti-fog test.
