Description

Technical Field

[0001] The utility model belongs to the technical field of automobile detection, and in particular relates to a device for detecting the sealing performance of an automobile in the rain. Background Art

[0002] Cars are an indispensable means of transportation in people's lives. In recent years, my country has vigorously developed the automobile industry. After the efforts of countless engineers, my country's new energy vehicle manufacturing level has leaped to the forefront of the world. After the car is assembled, it is necessary to test the sealing of the car body, that is, to detect whether the car body is leaking in the wind and rain. The traditional detection method is that the inspector drives the vehicle into the detection position and simulates the rainy environment by artificially spraying water to observe whether the car is leaking. This process is carried out continuously, during which the driver needs to close the doors and windows to keep the car closed. In order to ensure the continuity of each step and to ensure the safety of the driver, the driver sits in the car throughout the detection process. Due to process requirements, it is necessary to test the sealing of the vehicle in the off state, and the testing time is at least two minutes. In the hot summer, drivers are prone to heatstroke if they sit in a vehicle with the engine off for many times while working. At the same time, the existing vehicle sealing test can only simulate rain by spraying water, but cannot add wind during the water spraying process, and cannot achieve a more realistic rain condition, resulting in poor testing of the vehicle's sealing performance. After the test, there are a lot of water droplets hanging on the vehicle, and the next process can only be carried out after waiting for it to dry, which takes a lot of time and affects work efficiency. Utility Model Content

After the test is completed, the water droplets on the car body cannot be dried in time, which affects the work efficiency. The utility model device does not require the driver to stay in the car during the vehicle sealing test, which prevents the driver from being stuffy and hot. At the same time, it can also simulate the conditions of wind and rain, and the car body can be blown dry after the test is completed, which improves the work efficiency.
