Method for testing performance of vehicle door handle and device thereof

Abstract

The invention relates to a method for testing the performance of a vehicle door handle and a device thereof. The method comprises the following steps of: converting force born by the handle and the displacement of movement of the handle which are sensed by a force sensor and a displacement sensor in the opening process of the vehicle door into electric signals and transmitting the electric signals to a data collecting device ; converting two electric signals collected by the data collecting device into digital signals and transmitting the digital signals to a computer to carry out data processing and analysis; and displaying a real-time relation coordinate graph of the force and the displacement through a display. The device consists of the force sensor, the displacement sensor, a support rod, a magnetic disc, a universal joint and a fixture block. The testing method measures the force born by the handle and the displacement of the movement in the opening process of the vehicle door in real time, and gives the real-time relation coordinate graph of the force and the displacement. Therefore, the testing operation is convenient and rapid, and the testing result is correct and intuitionistic.

Description

technical field [0001] The invention relates to a method for testing the performance of a door handle of an automobile, and an operating device used for the performance testing of the door handle by adopting the method. Background technique [0002] At present, the performance test of the car door handle is generally carried out by using a relatively precise spring balance and a ruler that can memorize the peak value. Straightedge to measure. Specifically, when measuring the force, the spring scale is hooked to the handle with a scale hook, and the door is pulled through the spring scale. At the moment when the door is opened, the spring scale remembers the peak value at that time. Using this method is likely to cause errors in measurement values ​​due to differences in each positioning. When measuring the displacement of the door handle, the handle is pulled from the closed position of the door to the opening of the door, and a ruler is used to measure the displacement of...

Using this method is likely to cause errors in measurement values ​​due to differences in each positioning

When measuring the displacement of the door handle, the handle is pulled from the closed position of the door to the opening of the door, and a ruler is used to measure the displacement of the handle during this process. Obviously, this method cannot accurately measure the actual displacement during the moving process of the handle.

[0003] It can be seen that the above method cannot accurately measure the force and displacement of the handle during the process of pulling the handle to open the door. At the same time, the entire test method can only measure the maximum force and displacement of the door handle at the moment the door is opened, and cannot give the same time. The relationship between the force borne by the handle and the displacement of the handle during the door opening process can only give the subjective feelings of the testers at best, and the test results cannot provide sufficient technical support for technology development
