Problems solved by technology

Radio receivers and rod antennas are often installed on modern cars, and some car bodies are also equipped with auxiliary equipment such as wireless telephones, televisions, or small stoves and small refrigerators for heating food. The reliability of the performance of accessories in actual use requires performance testing during the production process of car body accessories, such as window switches, rearview mirror switches, door lights, buttons on car control channels, and gear position indicators. Lamp, AUX, USB, cigarette lighter, power supply and other reliability testing, but the current testing devices and testing methods for the reliability testing of these body accessories are not effective, the detection value is not accurate enough, the detection efficiency is low, and the degree of automation lower
