The invention discloses a whole-automobile parameter test system. The whole-automobile parameter test system comprises a linear guide rail device and at least two test units, wherein the linear guide rail device comprises at least one linear guide rail horizontally arranged; and each test unit comprises a laser emitting device and a photoelectric distance measuring device, the laser emitting device is used for emitting a laser plane to determine measuring base points, the photoelectric distance measuring device is used for measuring the distances among the measuring base points, and the at least two test unit are arranged on the linear guide rail device and are capable of moving along the linear guide rail device. According to the invention, the photoelectric distance measuring devices are adopted for measuring distances, the laser emitting devices are used for determining the base points, so that the precision of measurement data is effectively improved; in addition, the automatic degree of the devices is high, the test steps are low in number, and the problems of many steps, poor precision, occupied manpower resources and the like in a conventional measuring method are solved.
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 ...
