Description
Technical field
The utility model is related to equipment and technology in Automobile, and more particularly to a kind of internal car noise experiment microphone fixes dress
Put.
Background technology
Foundation《GBT 18697-2002 acoustics Vehicle Interior Noise measuring methods》It is transaudient at internal car noise experiment seat
Device position：The vertical coordinate of microphone be the surface of (nobody) seat with the intersection of backrest surface more than at (0.70 ± 0.05) m
(as shown in Figure 1, A:Unappropriated seat, B:Operating seat).Horizontal coordinate should be on the median plane (or plane of symmetry) of seat.
On operating seat, horizontal abscissa (puts the automobile of steering wheel then to the left in the right side) and is to the distance of seat median plane to the right
(0.20 ± 0.02) m (as shown in Figure 2, A:Unappropriated seat, B:Operating seat).
In-car seat microphone is fixed at present is fixed with adhesive tape, and this fixed form advantage is quick succinct, but actual bit
Put has error with the position of test method.
The content of the invention
The technical problems to be solved in the utility model, is to provide a kind of internal car noise experiment fixed device for microphone, can
Fast and accurately to position microphone position, reduce test error, improve operating efficiency.
What the utility model was realized in：A kind of internal car noise tests fixed device for microphone, including support, one
Individual microphone buckle and at least two fixes limited block, and the support includes the first supporting plate and the second supporting plate, described first
The bottom of supporting plate is connected with the end vertical of the second supporting plate；One is offered in first supporting plate and the second supporting plate
Opening is slided, the microphone buckle is slidably disposed on the slip opening of the first supporting plate, and described two fixations are spacing
Block is slidably disposed on the slip opening of the second supporting plate；A through hole, the through hole are offered on the fixed limited block
Through the fix bar of automotive headrest.
Further, second supporting plate is a L-shaped supporting plate, and first supporting plate is located at the end of L-shaped supporting plate
On the inside of portion, and the first supporting plate is fixed with L-shaped supporting plate by adjusting nut.
Further, the microphone buckle, two fixed limited blocks are slidably disposed in cunning by regulating bolt
On dynamic opening.
The utility model has the advantage of：Microphone buckle of the present utility model can be on the slip opening of the first supporting plate
Adjusted up and down, two fixed limited blocks can carry out moving left and right regulation in the second supporting plate, so that Mike's wind energy
Upper and lower and left and right adjusting is carried out, when Vehicle Interior Noise is tested, microphone can be fast and accurately fixed with the support, saved
Test period, reduces test error, improves operating efficiency.

The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the seat side structural representation that prior art is tested.
Fig. 2 is that the seat that prior art is tested overlooks face structural representation.
Fig. 3 is structural representation of the present utility model.
Fig. 4 is the structural representation of fixed limited block of the present utility model.
Fig. 5 is the structural representation of the utility model use state.
Specific embodiment
Refer to shown in Fig. 3 to Fig. 5, a kind of internal car noise tests fixed device for microphone, including 1, one, a support
Microphone buckle 2 and at least two fixes limited block 3, and the support 1 includes the first supporting plate 11 and the second supporting plate 12, described
The bottom of the first supporting plate 11 is connected with the end vertical of the second supporting plate 12；The supporting plate 12 of first supporting plate 11 and second
On offer a slip opening 4, the microphone buckle 2 is slidably disposed on the slip opening 4 of the first supporting plate 11,
Described two fixed limited blocks 3 are slidably disposed on the slip opening 4 of the second supporting plate 12；On the fixed limited block 3
Offer a through hole 31, fix bar 51 of the through hole 31 through automotive headrest 5.So microphone buckle 2 can be in the first support
Adjusted up and down on the slip opening 4 of plate 11, two fixed limited blocks 3 can be moved left and right in the second supporting plate 12.
In the utility model, second supporting plate 12 is a L-shaped supporting plate, and first supporting plate 11 is located at L-shaped
The tip inside of supporting plate, and the first supporting plate 11 is fixed with L-shaped supporting plate by adjusting nut 6.Such first support
Also easily can be arranged on device on automotive headrest with easy assembly and disassembly by plate 11 with L-shaped supporting plate.
In addition, the fixed limited block 3 of the microphone buckle 2, two is slidably disposed in slip by regulating bolt 7
On opening 4.Also can be configured by other fasteners.
In a word, microphone buckle of the present utility model can up and down be adjusted on the slip opening of the first supporting plate, and two
Individual fixed limited block can be carried out moving left and right regulation in the second supporting plate, so that Mike's wind energy adjusted with left and right up and down
Section, when Vehicle Interior Noise is tested, microphone can be fast and accurately fixed with the support, save test period, reduce examination
Error is tested, operating efficiency is improved.
Although the foregoing describing specific embodiment of the present utility model, those familiar with the art should
Work as understanding, the specific embodiment described by us is merely exemplary, rather than for the limit to scope of the present utility model
Fixed, those of ordinary skill in the art should in the equivalent modification and change made according to spirit of the present utility model
Cover in scope of the claimed protection of the present utility model.
