A new energy vehicle electronic control circuit board testing system and testing method

Abstract

The invention relates to a new energy automobile electronic control circuit board test system and test method, and the system comprises a pedestal, a detection device, and a clamping unit, the upper surface of the pedestal is provided with the detection device, and the detection device is provided with the clamping unit. According to the invention, the problems that the existing test system has asingle clamping mode for a to-be-tested circuit board, can only clamp a regular circuit board and has an improper clamping position for an irregular circuit when being used for testing the electroniccontrol circuit board of the new energy automobile at present, results of collision and vibration tests of the circuit board are influenced, so that data analysis is inaccurate, in addition, differentmachines need to be used for testing the collision test and the vibration test of the circuit board, the control function of the speed change during the collision test of the circuit board is single,and different damage degrees of the circuit board cannot be compared according to different speeds in actual traffic accidents can be solved.

Description

technical field [0001] The invention relates to the technical field of automotive electronics testing, in particular to a new energy automotive electronic control circuit board testing system and testing method. Background technique [0002] With the popularization of new energy vehicles, whether the internal control system of the vehicle can still be used to a certain extent in traffic accidents is also the focus of research by many automobile design manufacturers. In traffic accidents, the electronic control circuit boards inside new energy vehicles It is unavoidable that there will be a certain degree of collision and vibration damage. When the electronic control circuit board is damaged, whether it can continue to work requires a physical test of the produced circuit board through the test system, such as collision and vibration tests on the circuit board. Test the damage degree of the circuit board after collision and vibration, and then carry out power-on inspection, a...

AI Technical Summary

Problems solved by technology

[0003] At present, when testing the electronic control circuit board of new energy vehicles, there are the following problems: the existing test system has a single clamping method for the circuit board to be tested, and can only clamp the relatively regular circuit board. The position of the clamping circuit is not suitable, which will affect the results of the circuit board collision and vibration test, resulting in inaccurate data analysis; and for the circuit board collision test and vibration test, different machines need to be used for testing. The control function of the speed change during the crash test is single, and the different damage degrees of the circuit board cannot be compared according to the different speeds in the actual traffic accident.
