The noise control type intake hose comprises an intake hose, a hose expanding part formed at a certain portion of the intake hose, an inner cover formed inside the hose expanding part, a wall formed for obtaining a sealed area between the hose expanding part and the inner cover, and an inner hose protruding out from the inner cover to interconnect the inner side of the intake hose and the sealed area.
Description
- This application claims priority to Korean Application No. 10-2003-0069566, filed on Oct. 7, 2003, the disclosure of which is incorporated fully herein by reference.
- Generally, the present invention relates to a noise control intake hose adapted to reduce noise generated from the intake hose of a vehicle intake system.
- Typically, an intake system of a vehicle is used for purifying air intake into an engine and for dampening intake noise generated from the engine. The intake system is typically constituted by an intake hose, an air filter, and an air duct. However, there is a drawback in the intake hose designed for airflow in that it lacks a noise reducing function.
- An embodiment of the present invention provides an intake hose integrally formed with a noise control device for improving the noise reducing function, thereby increasing the productivity and minimize space in the intake system.
- In a preferred embodiment, the noise control type intake hose comprises an intake hose of an intake system for a vehicle. A hose expanding part is formed at a certain portion of the intake hose. An inner cover is formed inside the hose expanding part. A wall is formed for obtaining a sealed area between the hose expanding part and the inner cover. An inner hose is formed from the inner cover to interconnect the inside of the intake hose and the sealed area.
- For a better understanding of the nature and objects of the present invention, reference should be made to the following detailed description with the accompanying drawings, in which:
-
FIG. 1 illustrates a structure of a noise control type intake hose according to an embodiment of the present invention. - As shown in
FIG. 1 , a noise control type intake hose according to an embodiment of the present invention comprises ahose expanding part 22. Thehose expanding part 22 expands the hose to a predetermined width at a certain portion of anintake hose 20. Aninner cover 24 is formed inside thehose expanding part 22. Awall 26 is formed between thehose expanding part 22 and theinner cover 24 for sealing an inner portion of thehose expanding part 22. - In order for the sealed area formed between the
inner cover 24 and thehose expanding part 22 via thewall 26 to interconnect with the inner side of theintake hose 20, aninner hose 28 protrudes out in a prescribed length from a certain portion of theinner cover 24 to face the inner portion of thehose expanding part 22. If theinner hose 28 is extended in length inside thehose expanding part 22, low-frequency noise emitted from theintake hose 20 is reduced. On the other hand, if the length of theinner hose 28 is shortened, high-frequency noise of theintake hose 20 is reduced. Thus, it is preferable to adjust the length of theinner hose 28 according to the desired frequency to be reduced in relation to theintake hose 20. - The
hose expanding part 22,inner cover 24,wall 26, andinner hose 28 installed in theintake hose 20 are preferably integrally formed by molding. Thehose expanding part 22 according to the embodiment of the present invention is formed at a certain portion of theintake hose 20 of the intake system. Theinner cover 24 is formed inside thehose expanding part 22. Thewall 26 is installed to form a certain sealed area between thehose expanding part 22 and theinner cover 24. Theinner hose 28 extends out from theinner cover 24 to form a hole thereto, thereby interconnecting the inner side of theintake hose 20 and the sealed area formed inside thehose expanding part 22. - The sealed area between the
hose expanding part 22 andinner cover 24 functions as a resonator, thereby improving the noise reducing function generated from theintake hose 20. In order to improve the noise reducing function of a low-frequency noise, theinner hose 28 is extended in length, while theinner hose 28 is shortened in length for improving the noise reducing function of a high-frequency noise. - As apparent from the forgoing, there in an advantage in the present invention in that the intake hose of the intake system for a vehicle extends at a certain portion thereof, and the wall is mounted between the inner side of the expanded hose and an inner cover so as to obtain a sealed area therebetween. An inner hose is also formed for interconnecting the sealed area and the inner side of the intake hose, thereby improving the noise reducing function of the intake hose in a simple structure.
- The present invention may be modified, changed, replaced, or added as long as it is under the gist of the present invention and within the scope of claims.
