Abstract

The invention discloses a mounting structure and a noise testing device, and the mounting structure is used for installing a noise sensor so as to carry out the noise testing of a vehicle. The mounting structure comprises a mounting base, a mounting frame and a position adjusting structure, the mounting base is used for being arranged on the vehicle, the mounting frame is used for installing the noise sensor, and the position adjusting structure comprises a telescopic connecting structure and / or a spherical hinge connecting structure arranged between the mounting base and the mounting frame and used for adjusting the position of the mounting frame relative to the mounting base. The mounting structure provided by the invention can enable the placement position of the noise sensor to meet the dynamic test requirements, simplifies the mounting process of the noise sensor, facilitates the fixing of the noise sensor, and is reliable in fixing.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to an installation structure and a noise testing device. Background technique [0002] Because electric vehicles are driven by motors, compared with fuel vehicles, the source of vehicle noise is different. The noise source of fuel vehicles mainly comes from the engine, while the noise of electric vehicles mainly comes from road noise and wind noise. [0003] At present, the noise test for electric vehicles only has static noise test equipment. For dynamic tests, there is no special noise test equipment. Generally, the noise sensor is fixed to the outer surface of the vehicle body with tape, glue and other components, which are easy to drop during the test. Contents of the invention [0004] The main purpose of the present invention is to propose a mounting structure aimed at solving the problem of unreliable fixing of the noise sensor in the vehicle dynamic noise test [...
