Automobile door cover system durability test device capable of real-time monitoring

Abstract

The invention discloses an automobile door cover system durability test device capable of real-time monitoring. The automobile door cover system durability test device comprises a platform body, sidedoor cylinder brackets, a tail door cylinder bracket, engine hood cylinder brackets, side door cylinders, a tail door cylinder, an engine hood cylinder, a controller, a gas source, a solenoid valve, areversing valve and an electric proportional valve group, the side door cylinder brackets, the tail door cylinder bracket and engine hood cylinder brackets are fixedly arranged on the platform body,the gas source, the solenoid valve and the reversing valve are sequentially connected, the electric proportional valve group is connected with the side door cylinders, the tail door cylinder, the engine hood cylinder, the reversing valve and the controller respectively, one end of each side door cylinder is fixedly connected with the corresponding side door cylinder bracket, one end of the tail door cylinder is fixedly connected with the tail door cylinder bracket, one end of the engine hood cylinder is fixedly connected with each engine hood cylinder bracket, the other end of each side door cylinder is fixedly connected with a corresponding side door, the other end of the tail door cylinder is fixedly connected with the tail door, and the other end of the engine hood cylinder is fixedly connected with the engine hood. According to the automobile door cover system durability test device, output quantities of the cylinders are adjusted through adjusting a proportional relation thereof by adjusting the controller, the gas flow size can be effectively controlled by means of the electric proportional valves, so that the gas flow output is more stable.

Description

technical field [0001] The invention relates to the field of automobile door cover detection systems, in particular to an automobile door cover system durability test device for real-time monitoring. Background technique [0002] At present, the existing automobile door cover system durability test bench adjusts the air flow through the manual throttle valve to make the door opening and closing speed, the opening height of the hair cover and the tailgate meet the requirements of the test specifications, but in the process of the test, the ambient temperature and humidity Changes, as well as fluctuations in the air supply pressure of the entire air path will affect the size of the airflow, resulting in the opening and closing force and speed of the door, and the opening height of the hood and tailgate cannot meet the requirements of the test specifications, and the inspection of the patrol personnel found the problem during the test , artificially stop the test, but the test ...
