Description
Technical field
The utility model belongs to motor vehicle acoustic test equipment technical field, and in particular to a kind of acoustic sensor is rack-mounted
Put.
Background technology
With the continuous improvement of living standard, people also improve therewith to the demand of ride comfort, and automobile industry is more next
More pay close attention to the noise qualities of automobile each several part system.Acoustical testing analytical technology is the important means of the automobile noise control, therefore,
Acoustical testing research receives greatly concern in automobile research and development field.
At present in acoustic measurement field, generally sound signal collecting is carried out using acoustic sensor, due to different systems to be measured
System noise testing method is different, and the position of acoustic sensor arrangement is different, needs to adjust height, angle and between examining system
Distance.Generally only there is the support that traditional acoustic sensor arrangement is adopted elevating function and the elevation angle to adjust, and need to use scale again
The measurement of chi side is sized, estimates to medium, and regulation repeatedly increased workload, and measure error is big.In sum, in acoustics
In fields of measurement, needs one kind is simple to operate, measure accurate, folding and unfolding easily acoustic sensor holder device.
The content of the invention
The purpose of this utility model is to provide a kind of acoustic sensor support, can be applicable to the test of various acoustical testings
Journey is solving problem of the prior art.
The utility model is achieved by the following technical solution：A kind of acoustic sensor support, including with castor
Base stage, erects the column for having two sections to be concave on base stage, and leg surface is provided with rule, the groove of column
Inside it is provided with slideway；Also including the crossbeam of a section I-shaped, crossbeam is connected with column by the rotating shaft of crossbeam one end, on crossbeam
It is provided with rule and the bevel protractor for showing crossbeam and column angle；The rotating shaft merges with the slideway matching of column can be along cunning
Road is moved up and down；The laser infrared lamp for calibrating position is additionally provided with column.
Further：Be provided with one for clamping the clip of acoustic sensor in one end away from column of crossbeam, clip with
Crossbeam is connected by rotating shaft and can drive acoustic sensor in the rotation with surface parallel with column.
Further：The castor is the castor with skidding function.
The beneficial effects of the utility model are：This programme is capable of achieving the multi-direction regulatory function of acoustic sensor, it is ensured that not
In same acoustic measurement test, according to test needs, acoustic sensor locations are adjusted, simple structure, it is easy to operate improves work
Efficiency.
This support many places are provided with rule and bevel protractor, make experimental record accurately, and favorable repeatability is different to same money vehicle
The test of platform time and the test error before and after improving with chassis are less, as a result more accurately, and then improve operating efficiency.
Description of the drawings
Fig. 1 is acoustic sensor support main structure diagram；
Fig. 2 is acoustic sensor support side structure schematic view.
Number explanation in figure：1 is crossbeam, and 11 is rule, and 12 is bevel protractor, and 2 is column, and 21 is rule, and 3 is base
Platform, 4 is castor, and 5 is laser infrared lamp, and 6 is rotating shaft, and 7 is clip, and 71 is rotating shaft, and 8 is acoustic sensor.
Specific embodiment
It is as shown in Figure 1-2 a kind of acoustic sensor support of the utility model structure, including the base stage with castor 4
3, the column 2 for there are two sections to be concave is erect on base stage, leg surface is provided with rule 21, in the groove of column
It is provided with slideway；Also including the crossbeam 1 of a section I-shaped, crossbeam is connected with column by the rotating shaft 6 of crossbeam one end, on crossbeam
It is provided with rule 11 and the bevel protractor 12 for showing crossbeam and column angle；The rotating shaft merges with the slideway matching of column can
Move up and down along slideway and stop, being positioned by usual way during stopping, it is such as firm with bolt；Also set on column
There is the laser infrared lamp 5 for calibrating position.
Further：Being provided with one in one end away from column of crossbeam is used to clamp the clip 7 of acoustic sensor 8, clip
It is connected by rotating shaft 71 with crossbeam and acoustic sensor can be driven in the rotation with surface parallel with column.
Further：The castor is the castor with skidding function.
The utility model using method is as follows：
1. acoustic sensor is arranged in into horizon bar front end；
2. laser infrared lamp is lighted, the infrared ray alignment measured point launched using it；
3. according to infrared ray centering, band slide column and crossbeam are adjusted, according to rule illustrated dimension, adjust height, led to
Crossing rotating shaft swing bolster carries out angular adjustment；
4. by acoustic sensor bondage or appropriate location with adhesive tape bonding on crossbeam so that it is determined that examining system away from
From according to horizon bar high scale chi illustrated dimension, horizontal range being adjusted to test required size.
Preferably, the universal wheel with fixed dam should be selected to be arranged on bracket base lower section.Can more flexibly and
Backing positions are conveniently adjusted, a certain position to be measured can be secured the stand to by fixed dam.
Can be used using multiple support assorteds in actual application.
The beneficial effects of the utility model are, by using this multidirectional adjusting bracket, are capable of achieving acoustic sensor multi-party
To regulatory function, it is ensured that in different acoustic measurement tests, according to test needs, adjust acoustic sensor locations and be accurate to
Position, while this supporting structure is simple, it is easy to operate, improves operating efficiency.This support many places are provided with rule and bevel protractor, make reality
Test record accurate, favorable repeatability.To same money vehicle not test secondary on the same stage and with chassis improve before and after test when, due to
It is reproducible, can make that test data is more true and reliable, error is less, as a result more accurately, therefore can reduce experiment number, carries
High operating efficiency.
