Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, below will knot
Conjunction drawings and the specific embodiments are described in detail.
This utility model is poor for the fastness of mike in existing test, easily falls off and shakes,
The problem affecting the accuracy of noise testing data, it is provided that a kind of fixed support, is fixed on microphone position
On chair headrest, it is ensured that the firm installation of mike, promote the accuracy of test data.
As it is shown in figure 1, the fixed support of this utility model embodiment includes: the first support of fixing mike
1；The firm banking 2 being connected with described first support 1；And being connected with described firm banking 2, and set
The second support 3 being located on chair headrest 4.
The fixed support of this utility model embodiment, as in figure 2 it is shown, in test process, it is possible to by Mike
Wind 5 is fixed on the first support 1, and the first support 1 is by the second support 3 being connected with firm banking 2
Set is set on chair headrest 4, finally realizes being fixed to mike 5 side of chair headrest 4, to carry out
The collection of noise data.Therefore, the position of mike can be fixed on chair headrest by this fixed structure,
Ensure the firm installation of mike, and improve the accuracy of test data.
Wherein, such as Fig. 1, described fixed support at least includes two described first supports 1 being oppositely arranged,
And each described first support 1 is provided with mike fixing hole.
Owing to mike is often that length is bigger, fixed support is provided with at least two the first support 1, this
Two the first supports 1 are as in figure 2 it is shown, its place plane is parallel to each other and hangs down with the length direction of mike 5
Directly, mike 5 is fixed, so former and later two first supports 1 can be common through mike fixing hole
Effect, preferably ensures the stability connected.
It addition, in order to the laminating of further erection & lift is stable, firm banking 2 and the laminating of chair headrest 4
Face could be arranged to arc-shaped curved surface.
The fixed support of this utility model embodiment, can be the structure of metal material, the first support 1, solid
Determine base 2 and the second support 3 passes through one-body molded or is welded to connect.Metal material is fixed and props up
Frame, the second support 3 arranges an adjustment and connects end, and this adjustment connects two parts of end and is respectively arranged with correspondence
Multiple adjustment connecting holes.For different size of chair headrest, during installation, the i.e. optional suitably company of adjustment
It is tightened by bolt after connecing hole.
It should be understood, however, that the fixed support of metal material installs operation complexity, quality great Yi occurs
Come off, and vibration noise with mike junction influences whether the collection of data in driving, even tightly
Bring to a halt etc. and also can threaten the personal safety of driver and occupant under special operation condition.It is therefore advantageous to, institute
Stating fixed support is elastic support.
The use of elastic support, not only ensure that the steadiness of microphone position, and has shock-absorbing function concurrently,
Ensure that the accuracy of test noise data, the most more can guarantee that the safety of driver and occupant.Concrete,
First support 1 and firm banking 2 are rubber structure, and the second support 3 is elastic webbing.Second of elastic webbing
Frame 3 in use, can directly be set on various sizes of chair headrest 4, install faster convenience.
In the fixed support of this utility model embodiment, for the first support 1 of rubber structure, at two
In first support 1, the aperture of the mike fixing hole of first support 1 is less than the diameter of mike, and
Difference is in a preset range, and the aperture of this fixing hole is slightly less than the diameter of mike, it is achieved interference fit,
And the aperture of the mike fixing hole of another the first support 1 is equal to the diameter of mike.Mike and first
The connection of support 1, one end interference fit ensure that mike will not be sent out with radial direction at axis in test process
Raw play, other end interference fits limits mike radial motion, and installation is more convenient.
And the second support 3 of elastic webbing can realize directly through the through hole on the firm banking 2 of rubber structure
Connect.But owing to rubber structure can deform when stress, this connected mode, at the second support 3
When set is set on larger-size chair headrest 4, firm banking 2 can be produced by the second support 3 owing to tightening
Pulling force so that it is bend, the deformation of firm banking 2 influences whether again the first support 1, thus causes wheat
The fixing unstability of gram wind.
Therefore, in this embodiment, as shown in Figure 3 and Figure 4, described firm banking 2 is near described seat
Being provided with a junction on one side end face of headrest 4 and divide 21, described second support 3 is through described connecting portion
Divide the through hole of 21.
Second support 3 realizes the connection with firm banking 2, this connecting portion by the through hole of coupling part 21
Points 21 be smaller in size than firm banking 2, therefore, reduce the impact on firm banking 2 of second support 3,
Thus ensure that the stability that mike is fixing.
Additionally, as it is shown in figure 5, the contact surface of described coupling part 21 and described chair headrest 4 is arc
Curved surface.
Coupling part 21 is arranged on the firm banking 2 side end face near chair headrest 4, coupling part 21
Contacting with chair headrest 4, coupling part 21 is set to arc-shaped curved surface with the contact surface of chair headrest 4, with
Chair headrest 4 achieves application of a surface, it is ensured that the firmness of the second support 3 firm banking 2.
In sum, the fixed support of this utility model embodiment, simple in construction is easily achieved, it is possible to quick
It is fixed to mike easily test desired location, and ensures that its position does not changes, improve test
The accuracy of data.
Embodiment of the present utility model additionally provides a kind of test system, including fixed support as above.
This test system applies above-mentioned fixed support to carry out noise testing, it is possible to more firm sets mike
Put test desired location, and get and test data more accurately.
It should be noted that this test system is to apply above-mentioned support bracket fastened test system, above-mentioned fixing
The implementation of stent embodiment is applicable to this test system, also can reach identical technique effect.
