A plurality of mooring sections such as clamps, hooks, or the like, configured to support the above-mentioned harnesses or the like are formed at the refueling tray 41.
Hereinafter, a routing structure around the refueling tray 41 such as the harness or the like will be described.
First, the structure will be described with reference to FIG. 3. In FIG. 3, reference numeral 50 represents a main harness crossing the space while passing under the center cover 24 from a space (a vehicle front section space) surrounded by the front cover 21, the front side cover 22 and the inner cover 23 disposed in front of the straddling space 19 to a space (a vehicle rear section space) surrounded by the rear side body covers 29 and 29 disposed behind the straddling space 19. The main harness 50 is configured to bind a plurality of harnesses or the like configured to supply electric power from the battery B stored in the battery storage section 31 to electric parts disposed at the vehicle front section space side, the vehicle rear section space side, and therebetween, and has a relatively large diameter.
The main harness 50 extends rearward and downward from the head pipe 12 side toward a right side of a lower section of the battery storage section 31, and then extends toward the vehicle rear section. In the present embodiment, as shown in FIGS. 3, 5 and 6, the main harness 50 passes through a side portion (a right portion) of the circumferential wall section 42B of the enclosure section 42 in the refueling tray 41, and is routed between the lower side body cover section 25 and the refueling tray 41.
In addition, FIG. 7 shows a cross-section taken along line B-B of FIG. 3. As is apparent from FIG. 7, in the present embodiment, the main harness 50 is routed to overlap the refueling tray 41 when seen in plan view. That is, the main harness 50 is disposed at substantially the same height as the refueling tray 41 in the upward and downward directions of the vehicle.
As shown in FIG. 5, an annular clip 46 is fixed to the bridge section 45 of the refueling tray 41. The main harness 50 is wound on and hooked to the clip 46 and supported while positioned at a position of the side portion of the circumferential wall section 42B of the enclosure section 42.
Further, while not shown, the main harness 50 is supported by the battery storage section 31 and the storage box 30 at the vehicle rear section side from substantially a center of the vehicle, and routed between the battery storage section 31 and the storage box 30, and the rear side body cover 29. Accordingly, in the motorcycle 1, since the main harness 50 is supported by the battery storage section 31 serving as a battery case having high rigidity, the main harness 50 can be strongly supported. In addition, since the rear side body cover 29 of a lower periphery of the seat 16 is disposed not to overhang in the vehicle width direction, appearance characteristics can also be improved.
Next, as shown in FIGS. 3 and 4, in the present embodiment, a canister 60 configured to collect a gas (evaporated fuel) generated in the fuel tank F is disposed in a space in the upward and downward directions generated between the upper surface of the fuel tank F and the rear overhanging section 43B in the refueling tray 41.
As shown in FIG. 9, the canister 60 is formed in a columnar shape, and an annular holding body 61 formed of an elastic material is fitted onto an outer circumferential surface thereof. A fixing section 62 protruding from the outer circumferential surface is formed at the holding body 61. A through-hole formed in a slit shape and passing in a direction perpendicular to the radial direction of the holding body 61 is formed in the fixing section 62.
The canister 60 allows a holding claw body 63, which is fixed to the upper surface of the fuel tank F and standing upward, to pass through the through-hole of the fixing section 62 in order to position the canister 60. Accordingly, the canister 60 is supported while being lifted from the fuel tank F in a state in which an axis of the canister 60 is disposed in the leftward and rightward directions.
As shown in FIGS. 3 and 8, a charge hose 65 in communication with the canister 60 and the inside of the fuel tank F is formed between the canister 60 and the fuel tank F.
In addition, a purge hose 66 in communication with the canister 60 and an induction system of the motorcycle 1 is formed between the canister 60 and the induction system. In the present embodiment, the purge hose 66 is connected to the air cleaner 36 in the induction system. However, the purge hose 66 may be connected to any one of the intake pipe, the throttle body and the connecting tube in the induction system.
The purge hose 66 has a first purge hose 66A and a second purge hose 66B. One end of the first purge hose 66A is connected to the canister 60, and the other end is connected to one end of the second purge hose 66B via a purge control valve 67. The other end of the second purge hose 66B is connected to the air cleaner 36.
The charge hose 65 and the purge hose 66 will be described. One end of the charge hose 65 is connected to a position of a right side of the fuel filler opening 40 in the upper surface of the fuel tank F, passes through the forward side of the fuel filler opening 40 from the fuel tank F, is curved at a rear side, passes through a rear side of the fuel filler opening 40, and then is curved to extend further leftward to be connected to an end surface directed toward a right side of the canister 60.
That is, as shown also in FIG. 4, the charge hose 65 extends from the upper surface of the fuel tank F, and surrounds the peripheries of the fuel filler opening 40 and the enclosure section 42 serving as an area surrounding the fuel filler opening 40 in the refueling tray 41 to be routed to reach the canister 60. In such routing, a path of the charge hose 65 can be lengthily secured, and a gas (evaporated fuel) in the fuel tank F can be efficiently condensed. Accordingly, a collection ability of the canister 60 can be improved.
Further, in the present embodiment, as shown in FIG. 8, the charge hose 65 is disposed to be packed in (the upper surface of) the fuel tank F. For this reason, the charge hose 65 does not overhang in the vehicle width direction, and the vehicle can be miniaturized.
In addition, as shown in FIGS. 4 and 11, an L-shaped front hook section 80 extending downward is integrally formed with the bottom plate section 43F1 of the front overhanging section 43F in the refueling tray 41. The front hook section 80 is disposed at a position spaced apart forward from the enclosure section 42.
In addition, an L-shaped left hook section 81 is integrally formed with the left sidewall section of the enclosure section 42 in the refueling tray 41. In addition, an L-shaped hook section and a rear hook section 82 spaced apart from the hook section and including a plate section opposite thereto in the forward and rearward directions are integrally formed at the rear wall section of the enclosure section 42 in the refueling tray 41.
The charge hose 65 is placed on the front hook section 80, the left hook section 81 and the rear hook section 82 and supported by the hook sections from below.
Returning to FIG. 8, the first purge hose 66A has one end connected to an end surface of the canister 60 directed rightward and extending forward from the canister 60, and the other end connected to the purge control valve 67. The purge control valve 67 is supported by the main frame 13 via a bracket 13A and disposed at substantially a center in the vehicle width direction. In addition, one end of the second purge hose 66B is connected to the purge control valve 67 to extend rearward and curved to pass through a rear side of the canister 60, and further extends rearward to be connected to the air cleaner 36.
The purge control valve 67 is opened when an inner pressure of the first purge hose 66A is a predetermined value or more. When the purge control valve 67 is opened, a gas adsorbed to the canister 60 is supplied into the induction system via the first purge hose 66A and the second purge hose 66B. That is, in a downward direction of the gas from the canister 60 to the induction system, the first purge hose 66A is disposed at an upstream side of the purge control valve 67, and the second purge hose 66B is disposed at a downstream side of the purge control valve 67.
As shown in FIGS. 3 and 5, an L-shaped right hook section 83 is integrally formed with a right sidewall section of the enclosure section 42 in the refueling tray 41. In addition, as shown in FIG. 4, a plurality of left upper hook sections 84 are integrally formed with the left sidewall section at a position higher than the left hook section 81 of the left sidewall section of the enclosure section 42 in the refueling tray 41.
The first purge hose 66A is placed on the right hook section 83 and supported by the right hook section 83 from below. In addition, the second purge hose 66B is placed on the plurality of left upper hook sections 84 and supported by the left upper hook sections 84.
Further, the second purge hose 66B is placed on the upper surface of the fitting shaft section 31A extending forward and downward from the front section of the battery storage section 31 at the area passing through the rear side of the canister 60, and supported also by the fitting shaft section 31A from below.
In addition, in the present embodiment, a fuel lid cable 68 configured to rotatably manipulate the striker 35A is connected to the lid lock mechanism unit 35 supported by the extension section 43B1 in the rear overhanging section 43B of the refueling tray 41. The fuel lid cable 68 is routed to pass through the left side opposite to the side through which the main harness 50 passes, in both sides of the refueling tray 41. As shown in FIG. 8, the fuel lid cable 68 is routed to overlap the charge hose 65 when seen in plan view.
In addition, as shown in FIG. 4, a left intermediate hook section 85 is integrally formed between the left hook section 81 and the left upper hook sections 84 of the left sidewall section of the enclosure section 42 in the refueling tray 41. Then, the fuel lid cable 68 is supported by the left intermediate hook section 85.
In addition, as shown in FIGS. 3, 5 and 6, in the right portion of the refueling tray 41, a seat lock cable 69 configured to manipulate opening/closing of the seat 16 is routed at the upper side of the main harness 50. The seat lock cable 69 is supported by a support plate section 86 overhanging rightward from the vertical wall section 43R2 of the right overhanging section 43R in the refueling tray 41 from below. The support plate section 86 is lengthily formed in an L-shaped cross-section in the forward and rearward directions of the vehicle.
Since the seat lock cable 69 is lighter than the main harness 50 and disposed at the upper side of the main harness 50 to overlap the main harness 50 when seen in plan view, the motorcycle 1 can be designed to have a low center of gravity.
In addition, in the present embodiment, a plurality of locking sections configured to support a pipeline or the like are formed at the refueling tray 41. According to the above-mentioned configuration, since the number of parts configured to supply the pipeline or the like can be reduced and rigidity of the refueling tray 41 can be increased, the pipeline or the like can be strongly supported.
In addition, as shown in FIG. 8, in the present embodiment, when seen in plan view, the first purge hose 66A overlaps the seat lock cable 69 at a lower side thereof while overlapping the main harness 50 at a lower side thereof. In addition, the second purge hose 66B overlaps the charge hose 65 and the fuel lid cable 68 at an upper side thereof when seen in plan view.
In addition, as shown in FIG. 10, in the present embodiment, an opening section 90 is formed in the bottom plate section 43F1 of the front overhanging section 43F in the refueling tray 41, and the above-mentioned front hook section 80 extends downward from the rear edge section in the circumferential edge section of the opening section 90. Here, as shown in FIG. 6, the charge hose 65 supported by the front hook section 80 is formed to face the center cover 24 through the opening section 90. As shown in FIG. 9, the front sidewall section of the enclosure section 42 is disposed behind the opening section 90 in the periphery of the opening section 90, the vertical wall section 43F2 of the front overhanging section 43F is disposed at left, right and front sides, and the periphery of the opening section 90 is surrounded by the plurality of wall sections from front, rear, left and right sides.
The opening section 90 is installed to facilitate a routing operation of the charge hose 65. As the plurality of wall sections are formed at the periphery of the opening section 90, the liquid remaining in the refueling tray 41 can be prevented from flowing through the opening section 90, and the liquid can appropriately flow through a drain hose 70 connected to the refueling tray 41. As shown in FIG. 4, the drain hose 70 is connected to a drain hole 71 (see FIGS. 9 and 10) formed at a position at a rear lower side of the left sidewall section of the circumferential wall section 42B of the enclosure section 42, and extends downward.
Further, as shown in FIG. 10, in the present embodiment, an upper side of the rear wall section of the enclosure section 42 in the refueling tray 41 is curved upward, and an opening section 91 is formed in a curved area of the upper side. As shown in FIG. 6, the opening section 91 is formed to face the charge hose 65 supported by the rear hook section 82 toward the center cover 24. The opening section 91 improves an attachment property of the charge hose 65.
In the motorcycle 1 to which the structure according to the embodiment described as above is applied, since the main harness 50 passes between the rear section of the front side cover 22, the lower side body cover section 25 or the rear side body cover 29 that serves as a side body cover section and the refueling tray 41, a height of the straddling space 19 can be lowered. Accordingly, boardability can be secured. In addition, the weight of the motorcycle 1 can be reduced by a structure in which the main harness 50 is supported by the refueling tray 41 without installing the frame member extending to be inclined to a lower space of the center cover 24 under the straddling space 19.
In addition, in the motorcycle 1, as the main harness 50 overlaps the refueling tray 41 when seen in plan view, overhanging in the vehicle width direction of the main harness 50 can be suppressed, and a vehicle width dimension of the straddling space 19 can be suppressed.
In addition, in the motorcycle 1, as the charge hose 65 passes the fuel filler opening 40 and the periphery of the enclosure section 42 of the refueling tray 41, the lower side body cover section 25 can be disposed to suppress overhanging in the vehicle width direction.
Further, in the motorcycle 1, as the fuel lid cable 68 and the charge hose 65 overlap when seen in plan view, the overhanging of the fuel lid cable 68 in the vehicle width direction can be suppressed, and the vehicle width dimension of the straddling space can be suppressed.
In addition, in the motorcycle 1, as the seat lock cable 69 and the main harness 50 overlap when seen in plan view, the overhanging of the seat lock cable 69 in the vehicle width direction can be suppressed, and the vehicle width dimension of the straddling space can be suppressed.
Furthermore, in the motorcycle 1, as the first purge hose 66A overlaps the main harness 50 and the seat lock cable 69 when seen in plan view and the second purge hose 66B overlaps the charge hose 65 and the fuel lid cable 68 when seen in plan view, the overhanging of the first purge hose 66A and the second purge hose 66B in the vehicle width direction can be suppressed and the vehicle width dimension of the straddling space can be suppressed.
As a result, in the motorcycle 1, boardability can be further secured.
In addition, in the motorcycle 1, as the battery storage section 31 having sufficient rigidity to storage the battery B and the refueling tray 41 are connected by the fitting shaft section 31A, rigidity of the refueling tray 41 can be increased. For this reason, the pipeline or the like supported by the refueling tray 41 can be strongly supported.
In addition, in the motorcycle 1, as the charge hose 65 faces the center cover 24 through the opening section 90, the attachment property of the charge hose 65 can be improved and the working efficiency can be improved.
Hereinabove, while an embodiment of the present invention has been described, the present invention is not limited to the above-mentioned embodiment but may be appropriately varied without departing from the spirit of the present invention.
