Description
Technical field
Technical field of vehicle detection is the utility model is related to, more particularly to a kind of automobile leakage detection gas equipment.
Background technology
Automobile sealed performance is the precondition of auto NVH performance, and the sealing performance of automobile is primarily referred to as automobile bodies
Sealing performance.The compartment of automobile, although cannot be fully sealed, good leakproofness, comfort level and energy-efficient performance with automobile
It is related.
The advance of automobile sealed method for testing performance, device and means, and be the premise bar for improving automobile sealed performance
Part.Detection for automobile sealed performance, mainly detect it is several easily location of leak sealing situation, such as car door seam crossing,
Metal plate whip stitch and gluing etc..
At present, the method that automobile industry generally uses is：At a given pressure, the car by air blower to detected vehicle
Inflated in railway carriage or compartment, the air quantity of air blower when being maintained setting pressure i.e. leakage rate under pressure for this.Then, then into compartment fill
Enter colored gas, mainly to determine the position of leakage point by device by the observation or operating personnel of operating personnel, lead
Cause leakage point location determination difficult, and the colored gas entered in compartment can pollute vehicle interior trim.
The content of the invention
In view of the deficienciess of the prior art, the main purpose of the utility model is that car can be accurately positioned by providing one kind
The automobile leakage detection gas equipment of railway carriage or compartment air leakage point.
To achieve the above object, the utility model provides following technical solution：A kind of automobile leakage detection gas equipment, including car
Railway carriage or compartment, including pressure sensor, air blower, colored gas inflating pump and the transparent dressing attached plate being arranged on outside compartment, it is described transparent
Attach the part on plate with car contact and be provided with PE films.
Preferably, several air holes are provided with the transparent dressing attached plate.
Preferably, the transparent dressing attached plate is arranged at the gap on compartment.
The utility model has the following advantages that relative to the prior art, a kind of automobile leakage detection gas equipment of the utility model,
It is accurately positioned air leakage point by setting multiple transparent dressing attached plates, and transparent dressing attached plate is made of transparent plastic, very light weight,
And it is provided with PE films above, and such PE films can be directly attached on the crack between a door and its frame in compartment, when loading onto and removing very
Fast power-saving, under setting pressure, is inflated into the compartment of detected vehicle by air blower, is maintained air blast during setting pressure
The air quantity of machine is the leakage rate under pressure for this, then, then by colored gas inflating pump colored gas is filled with into compartment, such as
Fruit has air leakage point, then colored gas can be stopped by transparent dressing attached plate, and over time, the color at air leakage point can be got over
It is deep, facilitate operating personnel that air leakage point is accurately positioned.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of automobile leakage detection gas equipment of the utility model.
In figure：1st, compartment；2nd, pressure sensor；3rd, air blower；4th, colored gas inflating pump；5th, transparent dressing attached plate；6、PE
Film；7th, air hole.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of automobile leakage detection gas equipment, including compartment 1, including pressure sensor 2, air blower 3, coloured gas
Body inflating pump 4 and the transparent dressing attached plate 5 being arranged on outside compartment 1, the part contacted with compartment 1 in the transparent dressing attached plate 5 are set
It is equipped with PE films 6.
A kind of automobile leakage detection gas equipment of the utility model, it is by setting multiple transparent dressing attached plates 5 to be accurately positioned Lou
Gas point, transparent dressing attached plate 5 are made of transparent plastic, very light weight, and it is provided with PE films 6 above, and such PE films 6 can be with
Directly be attached on the crack between a door and its frame in compartment 1, the unusual fast power-saving when loading onto and removing, under setting pressure, by air blower 3 to
It is detected inflation in the compartment 1 of vehicle, the air quantity of the air blower 3 when being maintained setting pressure i.e. leakage rate under pressure for this,
Then, colored gas then by colored gas inflating pump 4 is filled with into compartment 1, if air leakage point, then colored gas can be saturating
Bright attaching plate 5 stops, and over time, the color at air leakage point can be deeper, facilitates operating personnel that leakage is accurately positioned
Gas point.
Preferably, several air holes 7 are provided with the transparent dressing attached plate 5.So it is provided that transparent in order to prevent
Attach plate 5 directly to come off, leakage hole plays the role of certain pressure release.
Preferably, the transparent dressing attached plate 5 is arranged at the gap on compartment 1.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
