Anti-pinch force testing method of electric car window in car door anti-pinch system

Abstract

The invention discloses an anti-pinch force testing method of an electric car window in a car door anti-pinch system. The anti-pinch force testing method includes step 1, checking and recording (also called inspecting) whether testing conditions and testing equipment are normal or not, especially whether the anti-pinch door window has anti-pinch action or not and whether values indicated by a force meter can be reset or not; step 2, uniformly selecting three points on the car window as testing points, and measuring three times on each testing point, namely measuring nine times in total. By the anti-pinch force testing method, factors like positions, steps, data processing and result judgment of anti-pinch force testing are standardized, so that operability and specificity in testing are realized; system errors are avoided in testing results as much as possible, so that an anti-pinch function of the anti-pinch system is reflected more objectively.

Description

technical field [0001] The invention relates to a method for testing anti-pinch force. Background technique [0002] With the development of the automobile industry, the requirements for automobiles have shifted from the previous durability to the prior safety and comfort, and the anti-pinch requirements of automobile power windows are also getting higher and higher. From the previous qualitative to the current quantitative, a series requirements. GB 11552-2009 "Protrusions inside Passenger Cars" standard proposes that the power window should be retracted before the anti-pinch force is greater than 100N. During the implementation process, many troublesome problems were encountered. First, during the measurement process, due to the different measurement points, the electric window has a clockwise or counterclockwise rotation tendency, which causes motion interference between the window and the glass sealing strip, resulting in a change in the anti-pinch force. Second, the ...

AI Technical Summary

Problems solved by technology

Encountered many troubles in the process of implementation

First, during the measurement process, due to the different measurement points, the electric window has a clockwise or counterclockwise rotation tendency, which causes motion interference between the window and the glass sealing strip, resulting in a change in the anti-pinch force

Second, the number of measurements is too small, the result sample is low, and the analysis problem is somewhat one-sided, and it is easy to ignore the objective factors such as the change of anti-pinch force caused by accident
