[0007] Patent Document 1: Japanese Patent Application Publication No. 2011-001927 Summary of the Invention

[0008] The problem that the invention aims to solve

[0009] In the intake control device assembly of Patent Document 1, the design avoids reducing the capacity of the vehicle's storage space by tilting the connector of the intake control device downwards. However, nowadays, with the increasing number of functions required by vehicles, the space under the storage compartment is extremely cramped, requiring an intake control device assembly that can further improve the flexibility of layout.

[0010] In view of the aforementioned problems in the prior art, the object of the present invention is to improve the layout of the peripheral structure of the intake control device assembly in a vehicle.

[0011] Methods for solving problems

[0012] The intake control device assembly of the present invention is disposed above the internal combustion engine of a vehicle and in the lower part of the storage space, and constitutes at least a portion of an intake pipe connected to the combustion chamber of the internal combustion engine. The intake control device assembly includes an intake control device and an inlet pipe.

[0013] The intake control device comprises: a main body having a first intake passage forming part of the intake pipe; a valve core rotatably supported inside the first intake passage and adjusting the amount of intake air flowing in the first intake passage; a valve shaft fixing the valve core and rotatably supported by the main body, and having an end protruding outward from the main body; and a rod fixed to the end and receiving an operating force that rotates the valve shaft.

[0014] The inlet pipe has a second intake passage, which forms part of the intake pipe, located downstream of the first intake passage, and is connected to the main body.

[0015] The operating force is obtained by utilizing the tension of the cable in the pole section.

[0016] The cable in question is the inner cable of Bowden Cable.

[0017] A fuel injection valve that injects fuel into the second intake passage is fixed to the inlet pipe via a fuel connector, which internally has a fuel passage connected to the fuel injection valve.

[0018] The fuel connector includes a connector portion that connects the fuel passage to the outside.

[0019] The connector portion is connected to a fuel hose that forms at least a portion of the fuel passage, which is connected to the vehicle's fuel tank.

[0020] The intake control device assembly is characterized in that...

[0021] The inlet pipe has a cable bracket for fixing the outer cable of the Bowden cable at a position downstream of the rod and upstream of the fuel injection valve.

[0022] In a planar view taken from both directions orthogonal to the rotational axis of the valve shaft and the direction of the intake passage extending from the first intake passage, the cable bracket and the rod are arranged together on one side divided by a central line, which is a straight line extended from the center line of the first intake passage.

[0023] In the plan view, the connector portion is positioned on the other side of the center line or directly above the center line, and protrudes from the fuel connector towards the upstream side of the second intake passage.

[0024] When the intake control device is viewed along the direction of the first intake passage, the space between the main body tangent line parallel to the rotation center axis and tangent to the edge of the main body and the main body, and the space between the rod tangent line orthogonal to the rotation center axis and tangent to the edge of the rod and the main body, constitutes a hose space in which at least a portion of the fuel hose is disposed.

[0025] According to the present invention, a cable bracket is provided in the inlet pipe portion downstream of the rod portion and upstream of the fuel injection valve to form a hose space. The cable bracket and the rod portion are arranged on one side of the center line of the first air intake passage, and the connector portion protruding towards the upstream side is arranged on the other side of the center line or directly above the center line. Therefore, the fuel hose can easily pass through the hose space to compactly form an air intake control device assembly.

[0026] At this time, since the connector is positioned on the other side or directly above the center line, the distance between the connector and the hose space can be maximized. In addition, the angle at which the fuel hose bends can be reduced, making it easier to configure the fuel hose.

[0027] By mounting the intake control unit assembly, which is compactly formed in this way, above the vehicle's internal combustion engine and below the storage space, the fuel hose can be positioned in the small space between the intake control unit assembly and the vehicle's storage space without compressing the storage space. This improves the size of the storage space and the layout of the space surrounding the intake control unit assembly.

[0028] The vehicle of the present invention is characterized in that it includes the above-described intake control device assembly, and a fuel hose connected to the connector portion of the intake control device assembly is disposed in at least a portion of the hose space of the intake control device assembly.

[0029] As a result, fuel piping, including fuel hoses, can be compactly arranged in a small space between the intake control unit assembly and the storage space, thus improving the size of the storage space and the layout of the surrounding space of the intake control unit assembly.

[0034] Figure 5 It indicates that in the prior art... Figure 4 The diagram shows the same relationships. Detailed Implementation

[0035] Hereinafter, embodiments of the present invention will be described using the accompanying drawings. Figure 1 This describes an intake control device assembly according to one embodiment of the present invention. The intake control device assembly 1 is disposed above the internal combustion engine in a vehicle such as a scooter and in the lower part of the storage space, and constitutes at least a portion of the intake pipe connected to the combustion chamber of the internal combustion engine.

[0036] like Figure 1 As shown, the intake control device assembly 1 includes: an intake control device 4, which includes a main body 3, and a first intake passage 2 that forms part of the intake pipe inside the main body 3; and an inlet pipe 6 connected to the main body 3, and a second intake passage 5 that forms part of the intake pipe inside the inlet pipe 6, the second intake passage 5 forming part of the intake pipe downstream of the first intake passage 2.

[0037] Figure 2 This shows the intake control device 4 as viewed along the central axis of the first intake passage 2. For example... Figure 2 As shown, the intake control device 4 includes: a valve core 7, which is rotatably supported inside the first intake passage 2 to adjust the amount of intake air flowing in the first intake passage 2; a valve shaft 8, which is fixed to the valve core 7 and rotatably supported on the main body 3, and has an end protruding to the outside of the main body 3; and a rod portion 9, which is fixed to the end and receives an operating force to rotate the valve shaft 8.

[0038] Figure 3 This is a plan view taken from two directions that are orthogonal to both the rotation center axis RA of the valve shaft 8 and the direction of the intake passage extending as the first intake passage 2. (See diagram below.) Figure 3 As shown, the operating force mentioned above is obtained by the tension of the cable 10 in the pole 9. The cable 10 is the inner cable of the Bowden cable 11.

[0039] A fuel injection valve 12, which injects fuel into the second intake passage 5, is fixed to the inlet pipe 6 via a fuel connector 13, which internally has a fuel passage connected to the fuel injection valve 12. The fuel connector 13 includes a connector portion 14 that connects the fuel passage to the outside. The connector portion 14 is connected to a fuel hose 15, which constitutes at least a portion of the fuel passage, and the fuel hose 15 is connected to the vehicle's fuel tank.

[0040] The inlet pipe 6 is located downstream of the intake pipe than the rod portion 9 and upstream of the intake pipe than the fuel injection valve 12, and has a cable bracket 17 for fixing the outer cable 16 of the Bowden cable 11.

[0041] When viewed from both the rotational axis RA of the valve shaft 8 and the direction of the intake passage extending as the first intake passage 2, the two directions are orthogonal. Figure 3 As shown in the plan view, the cable bracket 17 and the rod 9 are arranged together on one side after being divided by the center line CL, which is a straight line extended from the center line of the first air intake passage 2.

[0042] In the above plan view, the connector portion 14 is disposed on the other side after being divided by the center line CL or directly above the center line CL, and protrudes from the fuel connector 13 toward the upstream side of the second air intake passage 5.

[0043] like Figure 2 As shown, when the intake control device 4 is viewed along the direction of the first intake passage 2, the space between the main body tangent BL, which is parallel to the rotation center axis RA and tangent to the edge of the main body 3, and the space between the rod tangent LL, which is orthogonal to the rotation center axis RA and tangent to the edge of the rod 9, and the main body 3, constitutes a hose space HS, in which at least a portion of the fuel hose 15 is disposed.

[0044] In this structure, when the fuel hose 15 is connected to the fuel connector 13, one end of the fuel hose 15 is connected to the fuel connector 13, and the other end of the fuel hose 15 is connected to other pipes constituting the vehicle's fuel tank or fuel piping. This connection is made by guiding the fuel hose 15 through the outside of the main body 3 to the fuel tank side, but the portion of the fuel hose 15 passing through the outside of the main body 3 is configured to pass through the aforementioned hose space HS.

[0045] At this time, the cable bracket 17 of Bowden cable 11 is located on the inlet pipe 6 portion downstream of the rod portion 9 and upstream of the fuel injection valve 12, and the connector portion 14 of fuel connector 13 is located on the side opposite to the cable bracket 17 relative to the center line CL or directly above the center line CL. Therefore, the fuel hose 15 can be easily configured to pass through the center line CL side of the cable bracket 17 and through the hose space HS.

[0046] On the other hand, in vehicles such as scooter-type vehicles, when the intake control unit assembly 1 is positioned above the internal combustion engine and in the space below the storage compartment, as described above, the fuel hose 15 is compactly formed through the hose space HS and configured without reducing the storage space compared to the prior art. This situation uses... Figure 4 , Figure 5 As shown below.

[0047] Right now, Figure 4 The relationship between the position of the fuel hose 15 and the storage space 18 in the intake control device 4 of this embodiment is shown. Figure 5 The relationship between the two in the prior art is illustrated. For example... Figure 4 As shown, the portion of the fuel hose 15 outside the intake control device 4 is located within the hose space HS. Therefore, the lower end of the storage space 18 becomes a relatively flat plane, and the storage space 18 is not narrowed due to the influence of the fuel hose 15.

[0048] In contrast, Figure 5 In the prior art shown, since the cable bracket 17 is located on the intake control device 4, the fuel hose 15 passes above the intake control device. Therefore, the storage space 18 becomes quite narrow due to the presence of the fuel hose 15.

[0049] As described above, according to this embodiment, the cable bracket 17 is provided on the inlet pipe 6 to form a hose space HS, the cable bracket 17 and the rod 9 are arranged on one side of the center line CL of the first air intake passage 2, and the connector portion 14 protruding towards the upstream side is arranged on the other side of the center line CL or directly above the center line CL. Therefore, the fuel hose 15 can easily pass through the hose space HS, thereby enabling the intake control device assembly 1 to be compactly formed.

[0050] At this time, since the connector portion 14 is positioned directly above the other side or the center line CL, the distance between the connector portion 14 and the hose space HS can be maximized, thereby reducing the angle at which the fuel hose 15 bends. Therefore, the fuel hose 15 can be positioned more easily.

[0051] By mounting the intake control unit assembly 1, which is compactly formed in this way, above the internal combustion engine of the vehicle and in the space below the storage space 18, the fuel hose 15 is arranged in a small space between the intake control unit assembly 1 and the storage space 18 of the vehicle without compressing the storage space 18. Therefore, the storage space 18 can be enlarged, and the layout of the surrounding space of the intake control unit assembly 1 can be improved.

[0052] The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments. For example, the number of cables 10 that apply operating force to the lever 9 is not limited to two, but may be one. In this case, the single cable 10 is used to apply operating force in the valve opening direction to the lever 9, or the operating force in the valve closing direction may be applied by a spring.
