As shown in FIG. 1, a general room cooling system 10 for a vehicle is configured to include an evaporator 11, a compressor 12, a condenser 13, and so on.
The general operation of the room cooling system 10 so that refrigerant is evaporated, compressed, condensed, or distended during being circulated via the evaporator 11, the compressor 12, the condenser 13, and so on is well known to a person of ordinary skill in the art, a detailed description thereof will be omitted.
Meanwhile, the members such that the evaporator 11, the compressor 12, and the condenser 13 are connected with each other by a pipe 160 such that refrigerant is circulated.
The pipe 160 is fixed to a vehicle body by fixing apparatus 100.
An apparatus for fixing a pipe of a vehicle according to an exemplary embodiment of the present invention relates to the fixing apparatus 100 which is adapted to absorb vibration of various pipes 160 provided to a vehicle so as to suppress noise and to maintain a mounting position of constituent element. A pipe 160 of a room cooling system is illustrated in FIG. 1 for better understanding, the pipe 160 and the pipe fixing apparatus 100 according to an exemplary embodiment of the present invention are not limited thereto.
FIG. 2 is an exploded perspective view of an apparatus for fixing a pipe of a vehicle according to an exemplary embodiment of the present invention, FIG. 3 is an assemble perspective view of an apparatus for fixing a pipe of a vehicle according to an exemplary embodiment of the present invention, and FIG. 4 is a cross-sectional view taken along a line A-A in FIG. 3.
As shown in FIG. 2 to FIG. 4, an apparatus 100 for fixing a pipe of a vehicle according to an exemplary embodiment of the present invention includes a clip 110, a first rubber member 120, an insulation member 130, and a second rubber member 140.
The clip 110 is formed in a shape that overlapping two plates are bent. In addition, the first rubber member 120, the insulation member 130, and the second rubber member 140 may be made of a rubber material.
A fixation hole 111 and an assembly hole 113 are formed at one end of the clip 110. In addition, a mounting portion 115 is formed at the other end of the clip 110 bent and extended from the one end of the clip 110.
The fixation hole 111 may be a circle hole. In addition, one side of an external circumference of the fixation hole 111 is opened. Herein, a portion which is cut so as to open the one side of the external circumference of the fixation hole 111 will be called “cutting portion 111a”. 
The assembly hole 113 may be a circle hole. In addition, the assembly hole 113 is formed by a size to be smaller than the fixation hole 111.
The mounting portion 115 is formed in a hollow cylindrical shape such that the pipe 160 is inserted and fixed thereto. In addition, the mounting portion 115 is extended from one plate to the other plate in the other end of the clip 110 so as to form a cylindrical shape. That is, one plate is made to form the mounting portion 115 having the cylindrical shape and the clip 110 having the bent shape. Further, a penetration hole 117 bored to a radial direction is formed at the mounting portion 115 by a set section along a circumference thereof.
Meanwhile, the fixation hole 111 and the assembly hole 113 are formed by only one process in the clip 110 overlapping two plates.
The first rubber member 120 is formed in a cylindrical shape so as to be mounted to the fixation hole 11 and a fixation groove 121 is formed along an external circumference of the first rubber member 120. That is, an external circumference of the fixation groove 121 is sat on an internal circumference of the fixation hole 111 of the clip 110. Further, the first rubber member 120 is mounted to the fixation hole 111 through the cutting portion 111a. 
The first rubber member 120 supports the clip 110 which is disposed apart from a vehicle body on a state of being mounted to the fixation hole 111 of the clip 110. At this time, the first rubber member 120 is fixed to a vehicle body by a bush 125 which penetrates a center of the first rubber member 120.
The insulation member 130 includes an assembly portion 131 and an elastic portion 133.
The assembly portion 131 is formed in a cone shape so as to be easily inserted into the assembly hole 113 of the clip 110. That is, the assembly portion 131 is inserted into and penetrated to the assembly hole 113 of the clip 110 such that the insulation member 130 is mounted to the clip 110.
The elastic portion 133 is integrally formed with the assembly portion 131 in a bellows shape. In addition, the elastic portion 133 elastically supports the one end of the clip 110 to a vehicle body. Therefore, the insulation member 130 prevents that vibration being delivered to the clip 110 through the pipe 160 is directly delivered to a vehicle body.
At least one air hole 150 is formed at the elastic portion 133 such that it is easy to elastically transform. The air hole 150 is a passage for passing air in and out to interior and exterior of the elastic portion 133 according to elastic transformation of the elastic portion 133 by vibration of the clip 110.
The second rubber member 140 is formed in a hollow cylindrical shape so as to be inserted to the mounting portion 115 such that the pipe 160 is inserted into the hollow of the second rubber member 140. In addition, a protrusion 141 having a shape to correspond with the penetration hole 117 is formed at an exterior circumference of the second rubber member 140. That is, the second rubber member 140 is adapted that the protrusion 141 is inserted to the mounting portion 115 of the clip 110 so as to be sat on the penetration hole 117 such that the second rubber member 140 is not spun with the mounting portion 115. Further, a protruded rim 143 is respectively formed at both ends in an axial direction of the second rubber member 140 so that a radius of the protruded rim 143 is longer than a radius of an external circumference of the second rubber member 140. The protruded rim 143 prevents together with the protrusion 141 that the second rubber member 140 is escaped from the mounting portion 115.
In the hollow of the second rubber member 140, a plurality of bead 145 is radially protruded from an interior circumference. The bead 145 is smoothly transformed so as to fix the pipe 160.
A gap 147 is formed to be cut from the exterior circumference to the hollow of the second rubber member 140. The gap 147 is provided for inserting the second rubber member 140 to the mounting portion 115.
Meanwhile, the pipe 160 is inserted to the second rubber member 140 before the second rubber member 140 is mounted to the mounting portion 115.
As mentioned above, an apparatus 100 for fixing a pipe of a vehicle according to an exemplary embodiment of the present invention is adapted to fix the pipe 160 to the mounting portion 115 of the clip 110 by using the second rubber member 140, to fix the clip 110 to a vehicle body by using the first rubber member 120, and to elastically support the clip 110 to a vehicle body by using the insulation member 130.
Therefore, an apparatus 100 for fixing a pipe of a vehicle according to an exemplary embodiment of the present invention is adapted to insulate vibration being delivered from the pipe 160 to the clip 110 by the first rubber member 120 and the second rubber member 140 and to insulate vibration of the clip 110 by operation of the insulation member 130.
FIG. 5A and FIG. 5B are diagrams illustrating operations of an insulation member being applied to an apparatus for fixing a pipe of a vehicle according to an exemplary embodiment of the present invention.
As shown in FIG. 5A, in case that vibration of the clip 110 is slight, the elastic portion 133 of the insulation member 130 is not greatly transformed and the state of opening the air hole 150 is maintained.
Thus, air easily passes in and out through the air hole 150 such that vibration of the clip 110 is insulated by elastic transformation of the elastic portion 133.
As shown in FIG. 5B, in case that vibration of the clip 110 is great, the air hole 150 is closed as the elastic portion 133 of the insulation member 130 is greatly transformed.
Thus, the elastic portion 133 blocks that the clip 110 is contacted to a vehicle body and simultaneously air pressure is generated in interior the insulation member 130 so as to improve insulation effect.
According to an exemplary embodiment of the present invention, the apparatus 100 for fixing a pipe of a vehicle can suppress vibration of the clip 110 by operation of the insulation member 130 which is formed in the bellows shape. Furthermore, it may be minimized that vibration the pipe 160 is delivered to a vehicle body as vibration of the pipe 160 is insulated by three elements such as the first rubber member 120, the second rubber member 140, and the insulation member 130.
