Abstract

The invention discloses a width-adjustable vehicle cabin and a vehicle cabin verification platform thereof. The vehicle cabin comprises a vehicle head cabin assembling part and at least two vehicle cabin assembling parts, wherein any two vehicle cabin assembling parts can be in sealed connection, and any vehicle cabin assembling part and the vehicle head cabin assembling part can be in sealed connection; the foremost vehicle cabin assembling part is sealed by the vehicle head cabin assembling part, and the tail vehicle cabin assembling part is sealed by the tail end wall, so that the whole relatively sealed vehicle cabin is formed; the width of each vehicle cabin assembling part is adjustable; and the width of the headstock cabin assembling part is adjustable. The width, the length and thesize of the vehicle cabin can be adjusted.

Description

technical field [0001] The invention relates to the technical field of aerodynamic testing in a door opening and closing chamber, in particular to a vehicle cabin with adjustable width and a vehicle cabin verification platform. Background technique [0002] In recent years, with the rapid development and wide application of various assisted driving technologies, automobiles have gradually evolved from a means of transportation to a part of people's daily lives. The comfort of the interior environment of automobiles increasingly determines the consumption trend of the public. Therefore, it is very necessary to conduct a more comprehensive verification of the reliability of the body performance to improve the comfort of the car. Most of the vehicle cabin verification tests in the prior art are carried out using cabins of different volumes, the test cost is high, and there is a large gap with the actual cabin environment, and the accuracy of the data needs to be verified. Con...
