Adjustable electric support rod test rack system and test method thereof

Abstract

The invention discloses an adjustable electric support rod test rack system used for an automobile tailgate lifting system and a test method thereof. The system comprises three parts of a mechanical part, a control part and an electric measurement part. The mechanical part comprises a rack base, rack support structures, rack adjusting devices, tailgate limiting devices and a tailgate limiting hinge. The control part comprises a power supply and a controller. The electric measurement part comprises a force measurement module, a voltage and current measurement module, a Hall signal measurement module and an angular speed measurement module. The invention also discloses a test method for the tailgate lifting system of different automobiles through the system. According to the system, the tailgate of different structural sizes can be installed and tested, the opening and closing time of the tailgate can be controlled by controlling the movement speed of the support rod, and the kinematic and kinetic parameters related to the support rod in the opening and closing process of the tailgate can also be acquired so that the measurement accuracy is high and the test data are comprehensive.

Description

technical field [0001] The invention belongs to the field of supporting mechanisms for electric tailgates of automobiles, and in particular relates to an adjustable electric strut test bench system and a test method thereof. Background technique [0002] With the development of society and the improvement of economic level, automobiles, as an indispensable means of transportation in daily life, are becoming more and more popular in people's daily life. With the continuous progress of science and technology, automobiles are becoming more and more intelligent and humanized. The higher the level, more and more models are equipped with electric tailgates. Cars with electric tailgates can solve many inconveniences in our daily life. Electric tailgates seem to have become a part of the life of car owners. The electric tailgate of the prior art includes hydraulic supports, sensors and other components to realize the opening and closing of the tailgate. Such as Chinese patent 20161...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure the reliability and safety of the lifting mechanism of the automobile's electric tailgate, it is necessary to test the movement speed of the electric strut, the opening and closing time of the tailgate, and the kinematic parameters related to the strut during the opening and closing of the tailgate. Since the various specifications of the lifting mechanism testing system in the prior art need to match the various sizes of the tailgates of the test models, the testing of the lifting mechanism of the tailgate of the automobiles in the prior art all uses a type of electric motor. The tailgate adopts a special lifting mechanism test system. Since the lifting mechanisms of different models of electric tailgates are very different in size, installation method, and power, it is necessary to test the lifting of various models of electric tailgates. The whole testing process is more complicated
