Embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
Referring to Fig. 1 to Fig. 5, a kind of exhaust noise test microphone fixed support is shown in figure, including：Base 1 and bone
Frame 2, wherein, the end face of the base 1 is provided with sucker 3, the opposite side relative with the end face and the bone of the base 1
Frame 2 is connected, and the end of the skeleton 2, which is provided with the groove for clamping microphone, the groove, is provided with (the ginseng of cushion blocking 5
See Fig. 3 and Fig. 4).
Alternatively, the skeleton 2 includes：First support 21, second support 22 and groove support 23, wherein, described first
One end of support 21 is connected with the base 1, and the other end of the first support 21 is connected with the groove support 23, and described
One end of two supports 22 is connected with the base 1, and the other end of the second support 21 is connected with the groove support 23.Its
In, the cushion blocking 5 is arranged on the two ends of the groove support 23.
Alternatively, the material of base is rubber, and the material of skeleton is plastics, rubber size hardness 50HS -55HS, rubber
Base end face has a powerful electromagnetic chuck, for fixing as shown in Figure 1 with vehicle body.The base of elastomeric material and the skeleton of plastic material are viscous
Connect, the skeleton of plastic material ensures that the rigidity of whole support meets use requirement.
Fig. 5 show application of the support in exhaust noise test, the base of elastomeric material, the skeleton groove of plastic material
And the cushion blocking of elastomeric material plays bipolar damping effect.The support bracket fastened application of the utility model microphone not only ensure that
Microphone position does not change during actual road test, and has vibration-damping function concurrently, reduces the vibration of microphone, maximum limit
Degree ensures the accuracy of test noise data.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
Protection domain of the present utility model is also should be regarded as with retouching.
