Description
Technical Field
The present invention relates to a fuel pipe structure, and more particularly to a fuel pipe structure between a fuel tank and an internal combustion engine for a vehicle.
Background
In the related art, a fuel piping structure may be provided between a fuel tank and an internal combustion engine of a vehicle. The fuel piping structure may be constituted by a first pipe and a second pipe, and the first pipe and the second pipe may be connected by a joint member. In general, the joint member is formed of a connection pipe having a circular pipe body. Since the first pipe connected to the distal end of the joint member is coupled to the engine, the load generated by the vibration of the engine is directly received during the traveling of the vehicle. The load applied to the first pipe made of resin is further transmitted to the joint member, and rotation of the joint portion between the first pipe and the joint member or kinking of the first pipe may be caused. In this way, the force input by the engine shake is directly transmitted to the press-fitting portion of the pipe made of resin, and the pipe is deformed.

In the present embodiment, the fuel piping structure 100 is applied between a fuel tank (not shown) and an internal combustion engine of the vehicle 50, and is mounted on the vehicle body 52 (shown in fig. 1) of the vehicle 50 as a piping for purging (purge), for example, while the vehicle 50 may be provided with other members according to the requirements, such as a piping 54 as a piping for feeding (feed). However, the present invention is not limited to the specific structure of the vehicle 50 and the use of the fuel line structure 100, and may be adjusted as needed.
Specifically, in the present embodiment, as shown in fig. 1 and 2, the fuel piping structure 100 includes a first pipe 110, a second pipe 120, and a joint member 130. The first pipe 110 and the second pipe 120 connect a fuel tank, not shown, and the internal combustion engine, and the joint member 130 connects the first pipe 110 and the second pipe 120. The first pipe 110 and the second pipe 120 may be pipes for purging, and the first pipe 110 may be further provided as a resin hose corresponding to the engine side, but the present invention is not limited thereto. Further, the joint member 130 has a polygonal portion 132 between the first pipe 110 and the second pipe 120, and a fixing member 140 (shown in fig. 1) for fixing to the body 52 of the vehicle 50 is provided outside the polygonal portion 132.
Further, in the present embodiment, as shown in fig. 1 and 3, the joint member 130 is a connecting pipe and has a first end portion 134, a second end portion 136, and the polygonal portion 132 between the first end portion 134 and the second end portion 136. The first end 134 is formed in a circular pipe shape and provided in the first pipe 110, the second end 136 is formed in a circular pipe shape and provided in the second pipe 120, and the polygonal portion 132 is formed in a pipe body having a quadrangular external appearance and provided between the first pipe 110 and the second pipe 120. Further, a stopper 138a is provided between the first end 134 and the polygonal portion 132, and a stopper 138b is provided between the second end 136 and the polygonal portion 132. In this way, the joint member 130 can connect the first end 134 and the second end 136 to the first pipe 110 and the second pipe 120 with the polygonal portion 132 located at the middle portion as a hand-held portion, such that the stopper 138a abuts against the end of the first pipe 110 and the stopper 138b abuts against the end of the second pipe 120, and the polygonal portion 132 is located between the end of the first pipe 110 and the end of the second pipe 120. However, as long as the polygonal portion 132 of the joint member 130 has a shape other than a circular pipe body, the present invention is not limited to the polygonal portion 132 having a quadrangular shape, and it can be adjusted as required.
Further, in the present embodiment, as shown in fig. 1 and 4, a fixing member 140 is used for fixing to the vehicle body 52 (shown in fig. 1) of the vehicle 50, wherein the fixing member 140 is provided with an opening portion 142 (shown in fig. 4) corresponding to an outer side surface (i.e., the quadrangular shape) of the polygonal portion 132, and the polygonal portion 132 is provided inside the opening portion 142. Specifically, the fixing member 140 shown in fig. 4 is provided with two opening portions 142 and 144, the fuel pipe structure 100 as a pipe for purging shown in fig. 1 can be provided in the opening portion 142, and the pipe 54 as a pipe for feeding shown in fig. 1 can be provided in the opening portion 144, so that the fuel pipe structure 100 and the pipe 54 are connected to each other and fixed to the vehicle body 52 via the fixing member 140. However, in other embodiments, not shown, the fixing member 140 may be provided with only one opening portion 142 to correspond to the polygonal portion 132, but the present invention is not limited thereto.
As described above, in the present embodiment, since the fixing member 140 is provided on the outer side of the joint member 130 connecting the first pipe 110 and the second pipe 120, the joint member 130 can be further fixed to the vehicle body 52 via the fixing member 140 (as shown in fig. 1), and the entire fuel pipe structure 100 can be coupled to the vehicle body 52. In this case, the polygonal portion 132 of the joint member 130 is less likely to rotate relative to the fixed member 140 fixed to the vehicle body 52, and therefore, the joint region between the joint member 130 and the first pipe 110 is less likely to cause kinking or deformation of the first pipe 110 due to rotation, and the pipe is prevented from being deformed due to engine vibration.
In the present embodiment, as shown in fig. 4, concave-convex portions 142a corresponding to the polygonal portions 132 are provided in the opening portion 142. The uneven portion 142a is formed by a plurality of grooves and ridges alternately arranged, and the uneven portion 142a may be distributed over the entire area of the opening 142 corresponding to the circumferential direction, or may be formed only in a partial area. In this way, the uneven portion 142a on the opening 142 corresponds to the polygonal portion 132, and rotation of the joint member 130 can be further suppressed, and deformation of the pipe due to engine vibration can be prevented. Similarly, a similar concave-convex portion 144a may be provided in the opening portion 144, thereby further suppressing the rotation of the pipe 54 as shown in fig. 1, and further preventing the pipe from being deformed due to the engine shake. However, the present invention is not limited to the specific composition and arrangement of the concave and convex portions 142a and 144a, and may be adjusted according to the requirement.
Accordingly, in the present embodiment, as shown in fig. 1, the polygonal portion 132 of the joint member 130 is provided with a plurality of linear grooves 132 a. The plurality of linear grooves 132a are, for example, a plurality of linear reduced-thickness portions provided on at least one surface of the polygonal portion 132, but not limited thereto (may be provided on a plurality of surfaces of the polygonal portion 132). In this way, at least one of the surfaces of the polygonal portion 132 of the coupling member 130 is formed into an uneven surface via the groove 132a and corresponds to the uneven portion 142a on the opening 142 of the fixing member 140, so that the rotation of the coupling member 130 can be further suppressed, and the pipe can be prevented from being deformed by the engine shake. However, the present invention is not limited to the specific composition and arrangement of the groove 132a, and it can be adjusted according to the requirement.
In addition, in the present embodiment, as shown in fig. 1, the joint member 130 is of a straight-tube structure and is disposed with the extending direction L corresponding to the up-down direction of the vehicle 50 (i.e., the vertical direction in fig. 1), and the first pipe 110 and the second pipe 120 may be pipes not limited to the straight-tube structure and have a desired shape, so that the extending directions of the first pipe 110 and the second pipe 120 may be adjusted as required and fixed to the vehicle body 52 via a fixing structure, not shown. In this manner, the joint member 130 is provided so that the extending direction L corresponds to the vertical direction (i.e., the vertical direction in fig. 1) of the vehicle 50, rather than the joint member 130 being provided so that the extending direction L corresponds to the lateral direction (i.e., the horizontal direction in fig. 1) of the vehicle 50, the effect of attaching the joint member 130 can be improved. However, the present invention is not limited thereto, and can be adjusted according to the needs.
In the present embodiment, as shown in fig. 1, the fixing member 140 is made of a rubber material. Since the pipe 54 as a pipe for feeding and the fuel pipe structure 100 as a pipe for purging are fixed to the vehicle body 52 via the fixing member 140, the fixing member 140 made of a rubber material provides an attenuation effect before the engine vibration is transmitted to the vehicle body 52 via the pipe 54 as a pipe for feeding, and the influence on the pipe 54 as a pipe for feeding can be reduced, that is, the pipe 54 can be prevented from being deformed by the engine vibration. The same effect applies to the fuel pipe structure 100 as a pipe for purging, that is, the fixing member 140 made of a rubber material can prevent the first pipe 110 and the like of the fuel pipe structure 100 from being deformed by engine vibration.
Further, in the present embodiment, as shown in fig. 4, the fixing member 140 is provided with a protrusion 146 extending outward, and the fixing member 140 is fixed to the vehicle body 52 shown in fig. 1 with the protrusion 146 as a positioning structure. In this way, the fixing member 140 made of a rubber material can be more reliably fixed to the panel of the vehicle body 52. Further, since the fixing member 140 made of a rubber material is configured as a rigid body and is hard to be damped, the fixing member 140 may be provided with a groove 148 on the outer side surface to reduce the overall rigidity, thereby enabling the fixing member 140 to enhance its own damping force like a washer. However, the present invention is not limited to the material of the fixing member 140 and the arrangement of the protrusion 146 and the groove 148, and can be adjusted according to the requirement.
As described above, in the fuel pipe structure of the present invention, the first pipe and the second pipe connect the fuel tank and the internal combustion engine of the vehicle, and the joint member connects the first pipe and the second pipe, wherein the joint member has the polygonal portion between the first pipe and the second pipe, and the fixing member for fixing to the body of the vehicle is provided outside the polygonal portion. Preferably, the fixing member is provided with an opening portion corresponding to an outer side surface of the polygonal portion, and the polygonal portion is provided in the opening portion. Thus, compared to the prior art in which a connecting pipe having a circular pipe body is used as the joint member, the joint member used in the fuel pipe structure of the present invention is provided with the polygonal portion, and therefore, the joint member is less likely to rotate relative to the fixed member and the vehicle body. Accordingly, the fuel piping structure of the present invention can prevent the joint member from rotating, and further prevent the pipe from deforming due to engine vibration.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the embodiments of the present invention, and the essence of the corresponding technical solutions is not disclosed.
