Abstract
The utility model discloses a kind of automobile double pipeline air-inlet system, including air inlet pipe, air filter and escaping pipe, the gas outlet of air filter is connected with escaping pipe, air inlet pipe is by the first air inlet pipe, second air inlet pipe and short tube composition, first air inlet pipe and the second air inlet pipe are arranged side by side, the front port of first air inlet pipe is located at the rear of the second air inlet pipe front port, and first air inlet pipe front port and the second air inlet pipe front port towards identical direction, the rear port of first air inlet pipe and the rear port of the second air inlet pipe are connected with the front end of short tube, the rear end of short tube and the air inlet of air filter are connected.The utility model is using double air inlet pipeline designs, the length of two air inlet pipelines, the distance that so identical frequency sound waves are delivered to air filter from air inlet is different, so as to cause this frequency sound waves to reach the waveform phase difference of air filter, so as to reduce the induction noise of this frequency, and reduce air inlet to a certain extent and pressed (air inlet impedance), improve fuel efficiency.
Description
Technical field
The utility model belongs to automobile technical field, specifically, more particularly to a kind of automobile double pipeline air-inlet system.
Background technology
At present, the scheme of automotive air intake noise size is solved typically using the resistive and reactive muffler of addition.Resistance noise reduction
Device mainly increases sound-absorbing material in pipeline, and cost increase can be caused serious；Reactive muffler has following several ways：
1st, expansion cavity is increased --- need cabin to increase additional space, it is limited to low frequency acoustical absorptivity；
2nd, resonator is increased --- need cabin to increase additional space, it is limited to low frequency acoustical absorptivity；
3rd, wavelength tube is increased --- need cabin to increase additional space, it is limited to low frequency acoustical absorptivity；
4th, induction system line increase micropunch --- the high-frequency components in noise can only be directed to.
Utility model content
In view of the above-mentioned deficiency of prior art, technical problem to be solved in the utility model is to provide a kind of automobile double
Pipeline air-inlet system.
Technical solutions of the utility model are as follows：A kind of automobile double pipeline air-inlet system, including air inlet pipe, air filter and outlet
Pipe, the gas outlet of air filter is connected with escaping pipe, it is characterised in that：The air inlet pipe by the first air inlet pipe, the second air inlet pipe and
Short tube is constituted, and the first air inlet pipe and the second air inlet pipe are arranged side by side, and the front port of the first air inlet pipe is located at the second air inlet pipe front end
Mouthful rear, and the front port of the first air inlet pipe and the front port of the second air inlet pipe are towards identical direction, first air inlet
The rear port of pipe and the rear port of the second air inlet pipe are connected with the front end of short tube, the rear end of the short tube and entering for air filter
Gas port is connected.
For the ease of processing and fabricating, the cost of batch production is reduced, first air inlet pipe, the second air inlet pipe and short tube are
Integrative-structure, three passes through injection moulding.
Beneficial effect：The utility model is using double air inlet pipeline designs, and the direction of two air inlet pipeline inlet ends is identical, and
And the length of two air inlet pipelines, the distance that so identical frequency sound waves are delivered to air filter from air inlet is different, so that
This frequency sound waves is caused to reach the waveform phase difference of air filter, so as to reduce the induction noise of this frequency；The utility model
The problem of each frequency being likely to occur for gas handling system, rational silencing scheme can be provided, low frequency, length can be effectively reduced
The noise of wavelength, and reduce air inlet to a certain extent and pressed (air inlet impedance), improve fuel efficiency.The utility model is set
Meter is ingenious, simple in construction, implement easy, goes for any vehicle, bigger for large and medium-sized vehicle applicability meaning.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in figure 1, the utility model is made up of air inlet pipe 1, air filter 2 and escaping pipe 3.Wherein, air inlet pipe 1 is by first
Air inlet pipe 11, the second air inlet pipe 12 and short tube 13 are constituted, and three is structure as a whole, and passes through injection moulding.First air inlet pipe 11
Be arranged side by side with the second air inlet pipe 12, side-by-side configuration can be side by side up and down or left and right side by side.The He of first air inlet pipe 11
The length of both second air inlet pipe 12 is unequal, and specific length difference is determined according to actual needs.The front port of first air inlet pipe 11
Positioned at the rear of the front port of the second air inlet pipe 12, and the front port direction of the front port of the first air inlet pipe 11 and the second air inlet pipe 12
Identical direction.The front end of the rear port of first air inlet pipe 11 and the rear port of the second air inlet pipe 12 with short tube 13 is connected,
The rear end of short tube 13 is connected with the air inlet of air filter 2, and the gas outlet of air filter 2 is connected with escaping pipe 3.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member just can make many modifications and variations without creative work according to design of the present utility model.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to design of the present utility model in domain
Available technical scheme is tested, all should be in the protection domain being defined in the patent claims.
