Muffler structure in the sebific duct of road influences pipeline arrangement also larger.
Utility model content
The utility model is in view of the problems of the existing technology and insufficient, provides a kind of air conditioning for automobiles noise reduction modular construction,
Air-conditioning system noise reduction is solved the problems, such as in a manner of low cost, loss of weight, release automobile front chamber arrangement space, for narrow frequency noise feelings
Under condition, under not increasing any part additionally on the basis of original structure, by adjusting the assembling of pressure sensor on air-conditioning duct
Structure realizes the elimination of air-conditioning system specific frequency noise.
The utility model is to solve above-mentioned technical problem by following technical proposals：
The utility model provides a kind of air conditioning for automobiles noise reduction modular construction, and feature is, including air-conditioning duct, cylinder
The pressure sensor base and pressure sensor of shape, a slot hole is offered on the air-conditioning duct, and the length of the slot hole is more than the pressure
The diameter of force snesor pedestal, the pressure sensor base are fixed in the slot hole, and the top of the pressure sensor base is with being somebody's turn to do
Pressure sensor is threadedly coupled, and the inside of the pressure sensor base is enclosed with the inner surface of the pressure sensor to be set to form noise reduction
Chamber, the silencing cavity form 1/4 wavelength tube.
Preferably, the pressure sensor base is welded in the slot hole.
Preferably, the lower part of the pressure sensor base is arranged with to seal the pressure sensor and the pressure sensor
The O-ring of the junction of pedestal.
On the basis of common knowledge of the art, above-mentioned each optimum condition, can arbitrarily combine to get the utility model respectively compared with
Good example.
The positive effect of the utility model is：
The utility model combines the pressure sensor assembled on air-conditioning duct and pressure sensor base to form 1/4 wavelength
Pipe muffler, noise transmit loss increase, eliminate noise, optimize air-conditioning system pulsations, and technique afterwards with this configuration
Simply, air-conditioning duct does not add any parts, and arrangement is convenient, has good noise reduction to narrow frequency noise.

More than the diameter of the pressure sensor base 2, which is welded in the slot hole 11, the pressure sensor bottom
The top of seat 2 is threadedly coupled with the pressure sensor 3, the inside of the pressure sensor base 2 and the interior table of the pressure sensor 3
Face, which is enclosed, to be set to form silencing cavity 4, which forms 1/4 wavelength tube.Moreover, the lower part of the pressure sensor base 2 be arranged it is useful
O-ring 5 in the junction for sealing the pressure sensor 3 and the pressure sensor base 2.
The utility model combines the pressure sensor assembled on air-conditioning duct and pressure sensor base to form 1/4 wavelength
Pipe muffler, noise transmit loss increase, eliminate noise, optimize air-conditioning system pulsations, and technique afterwards with this configuration
Simply, air-conditioning duct does not add any parts, and arrangement is convenient, has good noise reduction to narrow frequency noise.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
These are merely examples, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art
Member can make these embodiments numerous variations or repair under the premise of the principle and essence without departing substantially from the utility model
Change, but these change and modification each fall within the scope of protection of the utility model.
