Description
technical field [0001] The invention relates to a lift-up and pull-down device used for reliability testing of an automobile tailgate. Background technique [0002] With the development of the automobile industry, my country's inspection of automobiles has become more and more standardized. Among them, any problems in the process of the tailgate switch of the car will bring a lot of unnecessary troubles to consumers. Therefore, the reliability of the tailgate switch of the car is one of the most important testing items in various car test standards. Door opening and closing reliability testing equipment has broad prospects. At present, the reliability of the equipment for testing the fatigue strength of the tailgate switch is poor, and it cannot simulate the real working conditions of the tailgate opening and closing, and it is impossible to make one device suitable for various models. Contents of the invention [0003] The purpose of the present invention is to provide ...
