Description

[0001] PIPE ASSEMBLY COMPRISING SAME [0002] The present invention relates to a pipe assembly including a resonator and a resonator,

The present invention relates to a pipe assembly including a resonator and a resonator.

Generally, a resonator installed in the intake and exhaust system is a device for reducing discharge sound of a specific frequency flowing along the intake and exhaust passages by using the principle of resonance. Such a resonator may have two configurations, each of which is manufactured by injection molding, and then bonded to each other through thermal fusion. Also, the resonator can be joined to the pipe by thermal fusion, and the melt generated in the heat-sealing process can spread in the direction perpendicular to the direction in which the pipe and the resonator face each other. Here, the fused portion which is fused while spreading in the vertical direction can be protruded and fixed from the surface where the pipe and the resonator are in contact to the inside and the inside of the pipe through which the air moves. Therefore, the adhered fusing material can be an element causing noise by the air flow. In addition, the resonator minimizes the air movement path during the connection with the pipe, and when the other end is formed in the portion joined by the fusion of the resonator and the pipe, the resonator and the pipe may be the same It is required to be formed with an inner diameter.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, this is merely an example and the present invention is not limited thereto.

In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The technical idea of the present invention is determined by the claims, and the following embodiments are merely a means for effectively explaining the technical idea of the present invention to a person having ordinary skill in the art to which the present invention belongs.

In an embodiment of the present invention, the coupling structure of the pipe assembly is mainly described, and the coupling structure is coupled by fusion, and the fusion bonding is performed when the connecting portion of the resonator and the one end of the pipe are coupled Will be described later. In addition, an inner diameter of a portion where the connecting portion and the pipe are coupled to each other may be equal to each other to form a flow path for air. Such a structure is to prevent turbulence, eddies and pressure drop in the air movement path by obstructing the air flow while the air is flowing, so as to supply smooth air.

Here, the one end of the pipe and the connecting portion may be formed with fusing structures corresponding to each other on the surfaces to be frictioned with each other. Here, the fusing structure may include a friction between a flat surface and a flat surface including a flange shape, a friction between a groove and a projection, , Frictions of the surfaces due to the formation of the first and second grooves from the plane, friction of the protrusions and protrusions, friction of the protrusions and the plane. And, the correspondence means a combination of structures that can be formed by the above-described structures.

Particularly, in the case of the friction between the protruding portion and the groove portion, the protruding length of the protruding portion is formed longer than the depth of the groove portion so that the melt is formed and fused so that the fusing force can be further increased as the fused area by the groove portion is increased. And the groove of the structure is capable of preventing the melt from flowing into the pipe assembly because the groove can receive a predetermined amount of the melt.

Such a structure can be variously modified by a person skilled in the art. For example, the projecting portion and the groove portion can be formed at one end of the pipe or at the side of the connecting portion, so that the uneven structure can be modified.

Further, when the melt is accommodated by the groove, the amount of melt to be generated by melting the friction surface may be determined depending on the amount of the melt that can be accommodated since it is a factor that determines the distance that the resonator and the pipe are pressed and moved with respect to each other.

Hereinafter, to explain one embodiment of the present invention, referring to FIGS. 1 to 4, a fusing structure formed on a connecting portion and a fusing structure including a protrusion and a groove portion for fusing a pipe and a connecting portion will be described below. .

1 is a perspective view of a pipe assembly 10 according to an embodiment of the present invention.

Referring to FIG. 1, a pipe assembly 10 may include a resonator 100 and a pipe 1. Here, the resonator 100 may include a cover member 110 and an inner member 120, and a part of the inner member 120 may be inserted and fixed inside the cover member 110. And the cover member 110 may include a connection portion 110a that can be engaged with the pipe 1. [ The connection portion 110a may be formed in a flange shape and the pipe 1 may be formed in a shape corresponding to the flange shape.

The pipe 1 may be fused to the resonator 100. In the resonator 100, the connecting portion 110a is formed in the shape of a flange, so that the contact area can be increased as compared with a pipe formed in a tube shape. Here, since the contact area can be proportional to the adhesive force when fused, the increase in the contact area means that the adhesive force between the pipe and the resonator is increased.

FIG. 2 (a) is an exploded perspective view of a resonator 100 according to an embodiment of the present invention, and FIG. 2 (b) is a cross-sectional view of the resonator 100.

2 (a) and 2 (b), the resonator 100 may include a cover member 110 and an inner member 120, and the inner member 120 may be disposed inside the cover member 110 And some of them may be inserted and joined to each other. The cylindrical inner member 120 may have a plurality of partition walls 121 extending radially from the outer circumferential surface thereof, and the partition wall 121 may be in contact with the inner peripheral surface of the cover member or the like. At this time, the cylindrical inner member 120 may have a plurality of through holes 122 formed on the outer circumferential surface thereof. In order to reduce the noise generated by the air passing through the inside of the resonator 100, Lt; / RTI > Here, the soundproof space 121a may be divided into a plurality of spaces by the partition 121, and the size and shape may be changed according to the frequency of the noise.

In order to reduce the noise, it is possible to design a structure that prevents the airflow from being impeded. Also, one embodiment of the present invention is also applicable to the case where the resonator 100 and the pipe 1 are formed in the pipe assembly 10 It is possible to prevent burrs. The coupling member 110a of the resonator 100 and the one end of the pipe 1 are heated to a melting point of the resonator 100 and the pipe 1 by means of a predetermined device or the like It can be rubbed. The melting point of the resonator 100 and the pipe 1 may be different from each other or may be the same.

When the melting points are formed identically, the flange-shaped connecting portion 110a is fused to the flange-shaped pipe 1, for example, and the pipe 1 and the connecting portion 110a can be simultaneously melted and fused to each other, A member formed with a lower melting point may be melted and fused. In the two cases, when two flange-shaped friction surfaces are fused and fused, they can exhibit similar effects to each other.

2 (b), a portion to be melted is separately provided so as to protrude toward the friction surface by a fusing structure 111, and a flange (not shown) is provided at a position corresponding to the fusing structure 111 and the fusing structure 111, The melting points of the connecting portion 110a and the pipe 1 may be different from each other.

That is, when the melting point of the resonator 100 having the fused structure 111 formed thereon is lower than that of the fused structure 111, the pressing distance is determined according to the amount of the fused structure 111 to be melted, It is possible to prevent the melt from protruding and sticking to the inside of the pipe assembly 10. The melt projecting and fixing to the inside may obstruct the flow of air flowing inside the pipe assembly 10 and may cause noise.

Therefore, when the fusing structure 111 is formed, if the melting point is the same, the area of the fusing structure 111 that is in contact with the fusing structure 111 is also melted at the same time and the amount of the melt is difficult to be measured. There is a possibility that the air is blocked and adhered to cause noise.

3 (a) is a side view showing the state before the fusion of the resonator 100 and the pipe 1 according to the embodiment of the present invention, and FIG. 3 (b) Side view.

Referring to FIG. 3, the pipe 1 and the resonator 100 may be disposed facing each other to be fused. For example, the friction surface may be arranged so that the resonator 100 and the pipe 1 are formed in a flange shape and face each other. In the case of a flanged frictional surface, the engaging force can be further increased since the engaging area is wider than the end of the cylindrical shape.

As shown in Fig. 3 (a), the resonator 100 and the pipe 1 can be pressurized by a predetermined distance in the facing direction from the arrangement step facing each other to the fusion step of Fig. 3 (b). The predetermined distance may vary depending on the amount of the melt 111a. For example, the melt 111a may be determined within a distance that the melt 111a is not adhered to the pipe assembly 10 due to the pressure. That is, when the amount of the melt 111a is large, the moving distance while being pressurized may be shorter than that when the amount of the melt 111a is small. Here, even when the amount of the melt 111a is small, it can be welded over an area of 50% or more of the contact surface of the flange shape.

4 is a partial cross-sectional view for explaining a groove 1a of a pipe 1 corresponding to a resonator 100 according to an embodiment of the present invention.

Referring to FIG. 4, a groove 1a is formed on a surface of the pipe 1 contacting the resonator 100 and a fusion structure 111 of the resonator 100 is located at a position corresponding to the groove 1a, As shown in FIG.

The groove 1a is formed on the side of the pipe 1 through FIG. 4, but the fused structure 111 and the groove 1a may have a structure corresponding to each other, and may be positioned irrespective of the member to be formed. For example, the groove 1a may be formed on the side of the resonator 100, and the fused structure 111 may be formed on the side of the pipe 1. However, a case in which the fused structure 111 is formed on the side of the resonator 100 through FIG. 4 and the groove 1a is formed on the side of the pipe 1 will be described later.

In addition, as described above with reference to FIG. 2, when the fused structure 111 is included, the melting points of the two members may be different from each other, and the case of exemplifying the same through FIG. 4 is also applicable.

For example, the groove 1a and the fusing structure 111 can be rotated and pressurized for fusing, and the temperature can be raised by the frictional heat up to the melting point of the friction surface by rotation and pressing. Here, the friction surface may be the groove 1a and the fusing structure 111, but the fusing structure 111 having a relatively low melting point may be melted and may be in the form of the melt 111a. Since the groove 1a is not melted, the shape of the groove can be maintained. The melt 111a can flow into the groove 1a in which the shape is maintained and the melt can be adhered to the groove 1a.

By maintaining the shape of the groove (1a), the fusion area by the melt can be increased more than when it is in contact between the flat flanges, and the adhesive force can be increased by this wider contact area.

Further, a plurality of such grooves 1a may be formed to increase the contact area, and the shape of the grooves 1a may be formed in a shape of a trapezoid, a triangular groove, or the like, and may be fixed with a fastening structure after fusion.

The protruded length of the fused structure 111 may be longer than the depth of the groove 1a in order for the melt 1a to be fused over the flange contact area of the connection part 110. [ This is because the volume of the fused structure 111 that is longer is changed into the state of the melt 111a and can be fused over the flange contact area by the above pressing.

5 is a partial cross-sectional view for explaining a resonator 100 and a groove 1a of a pipe 1 according to another embodiment of the present invention

Referring to FIG. 5 (a), a plurality of fusing structures 111 may be formed by a fusing structure in which the grooves 1a and the protrusions are combined. When the plurality of fused structures 111 are fused with the corresponding plurality of grooves 1a, the fused area after fusion can be made wider. The widely formed fused surface can enhance the adhesion between the pipe 1 and the resonator 100. The grooves 1a and the protrusions 111 corresponding to the grooves 1a may be fused to each other only on the frictional surface when the protrusions or the melted portions on the grooves 1a are small. Therefore, the friction surface can be formed so as to be positioned besides the direction in which the pipe 1 and the resonator 100 face each other.

Referring to Fig. 5 (b), a friction surface may be formed on the side surface from the direction in which the pipe 1 and the resonator 100 face each other. In this case, the width of the groove 1a may be larger than the width of the fusing structure 111 so that the fusing structure 111 as a protrusion can be inserted, and the fusing groove 1b may be formed inside the groove 1a have. Here, the width or diameter of the fused groove 1b is formed to be smaller than the width or diameter of the fused structure 111, and the fused groove 1b and the fused structure 111 can be melted and fused by contact with each other. The fused surfaces formed by the fusion bonding are in contact with each other by a difference in diameter between the surfaces of the grooves 1a and the fused structures 111 and the fused grooves 1b and the fused structures 111, Can be formed. A " C " type fused surface including a facing surface can be formed. That is, the portion forming the fusion groove 1b and the projected fusion structure 111 may be melted and fused to each other in a predetermined amount.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, . Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by equivalents to the appended claims, as well as the appended claims.
