A vehicle parameter testing system

Abstract

The invention discloses a vehicle parameter test system. The vehicle parameter testing system includes: a linear guide rail device, which includes at least one horizontally arranged linear guide rail; at least two test units, each of which includes a laser emitting device and a photoelectric distance measuring device, and the laser The emitting device is used to emit a laser plane to determine the measurement base point, and the photoelectric distance measuring device is used to measure the distance between the measurement base points, wherein at least two test units are arranged on the linear guide device, and can be The linear guide rail movement. The vehicle parameter testing system of the present invention uses a photoelectric distance measuring device to measure the distance and a laser emitting device to determine the base point, which can effectively improve the accuracy of measurement data. Moreover, the automation of the equipment is high, and the steps required for the test are few, which solves the problems of traditional measurement methods such as many steps, poor accuracy, and occupation of human resources.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a vehicle parameter testing system. Background technique [0002] In order to check whether the structure of the new trial production or the current production car meets the design requirements, and to find out the problems in design, manufacturing and assembly; or to measure the size of the sample car with unknown parameters and provide reference data for car designers, etc., it is usually necessary to measure the whole car Geometric parameters. [0003] At present, most vehicle manufacturers usually use conventional steel tape measure, spirit level, plumb and other equipment to measure the external dimension parameters and passability parameters of the vehicle. Since the relevant measured parameters are all obtained by indirect measurement, and the whole testing process requires several steps to complete, it is easy to accumulate errors and reduce the testing accuracy. And because ...

AI Technical Summary

Problems solved by technology

Since the relevant measured parameters are all obtained by indirect measurement, and the whole test process needs several steps to complete, it is easy to accumulate errors and reduce the test accuracy

And because the operation is complicated, at least two technicians are required to complete it together, which takes up human resources
