In the present embodiment, the side portions 46B, 46C are connected to the lower end of the center portion 46A. In other words, the side portions 46B and 46C of the present embodiment are formed in a substantially U-shape (or a substantially C-shape) that is open upward by the entirety of the left side portion 46B and the right side portion 46C, and the upper end of the open end that is formed in the substantially U-shape (or the substantially C-shape) is connected to the upper rear portion of the center portion 46A from the outside in the lateral direction.
An intake port 61 for taking in the traveling wind supplied to the power unit 12 is formed between the center portion 46A, the left side portion 46B, and the right side portion 46C. The intake port 61 is formed by a surrounding shape of the center portion 46A, the left side portion 46B, and the right side portion 46C. The intake port 61 is opened left and right by the center portion 46A, and has a left intake port 61A and a right intake port 61B. Here, the side portions 46B and 46C are inclined forward as they come downward in side view (see fig. 2). The intake port 61, i.e., the left intake port 61A and the right intake port 61B, are configured as follows: the width in the left-right direction increases as the direction goes to the rear in front view. In the intake port 61, the traveling wind can be easily taken in as compared with a case where the width is not increased further rearward.
In the front view shown in fig. 4, the opening shapes of the left and right air inlets 61A, 61B of the present embodiment are respectively formed by: left and right outer edges 61A1, 61B1 provided at left and right outer ends; upper edges 61A2, 61B2 extending from upper ends of the left and right outer edges 61A1, 61B1; lower edges 61A3, 61B3 extending from lower ends of the left and right outer edges 61A1, 61B1; left and right inner edges 61A4, 61B4 connecting the vehicle width direction inner ends of the upper edges 61A2, 61B2 and the lower edges 61A3, 61B3 to each other.
That is, in front view, the opening shape of at least a part of the intake port 61 is formed by the outer edges 61A1, 61B1, the upper edges 61A2, 61B2, and the lower edges 61A3, 61B3 in the left-right direction.
A DRL (first lighting fixture) 41 is disposed on the outer peripheral side of the air inlet 61. The DRL41 is disposed on the front surface of the side portions 46B, 46C. DRL is an abbreviation for Daytime Running Light (daytime running light). The DRL41 includes a resin case 41A, a light emitting body (not shown) accommodated in the case 41A, and a lens 41B for transmitting light of the light emitting body. The light emitting body of the DRL41 is composed of, for example, a light source main body not shown and a light guide member not shown that guides light of the light source main body. In the DRL41, the light emitter emits light and the lens 41B appears to emit light. The light emitting unit 41C of the present embodiment is constituted by a light emitting body, not shown, and a lens 41B.
As shown in fig. 4, the light emitting portion 41C includes a pair of right and left light emitting portions 41D, 41E. The light emitting portions 41D and 41E are formed symmetrically. The light emitting portions 41D, 41E have, in front view: the side portions 41D1, 41E1 extending in the up-down direction, the upper portions 41D2, 41E2 extending inward in the vehicle width direction from the upper ends of the side portions 41D1, 41E1, and the lower portions 41D3, 41E3 extending inward in the vehicle width direction from the lower ends of the side portions 41D1, 41E 1.
The side portions 41D1, 41E1 of the light emitting portion 41C extend along the outer edges 61A1, 61B1 of the intake port 61 in the left-right direction, respectively. The upper portions 41D2, 41E2 of the light emitting portion 41C extend along the upper edges 61A2, 61B2 of the air inlet 61, respectively. The lower portions 41D3, 41E3 of the light emitting portion 41C extend along the lower edges 61A3, 61B3 of the air inlet 61, respectively.
In the present embodiment, the lower portions 41D3, 41E3 are arranged to enter below the center portion 46A of the headlamp bracket 46. In particular, in the present embodiment, the left lower portion 41D3 and the right lower portion 41E3 are connected to each other below the center portion 46A to form an integral shape. The pair of right and left light emitting portions 41D, 41E has a portion disposed below the air inlet 61. The light emitting portion 41C of the present embodiment is formed in an inverted U shape integrally with the light emitting portion 41D on the left side and the light emitting portion 41E on the right side.
The housing 41A of the DRL41 is fixed to portions of the side portions 46B, 46C corresponding to the outer peripheral portion of the air inlet 61 by fastening members 72. The DRL41 extends along the periphery of the air inlet 61.
In the DRL41 of the present embodiment, the housing 41A is formed to have a larger width in each portion than the light emitting portion 41C extending in the shape of an inverted U in front view. The housing 41A is configured to have a larger rearward width. The housing 41A has a wall surface on the intake port 61 side that is inclined toward the intake port 61 side as it goes rearward. Thus, the traveling wind from the front is guided by the case 41A and is easily taken into the left and right air inlets 61A, 61B.
Since the DRL41 that is easily noticeable is disposed in most of the outer periphery of the air inlet 61, the air inlet 61 can be disposed in front, and the air inlet 61 is relatively less noticeable. Therefore, the appearance of the saddle type vehicle 10 is improved as compared with the case where the intake port 61 is easily noticeable.
Further, the DRL41 is not disposed in the center portion 46A, and a notch, a fastening hole, or the like for supporting the DRL41 is not required, which can contribute to the enhancement of the strength of the center portion 46A.
A beam lamp (second lighting fixture) 42 is disposed inside the surrounding shape of the DRL 41. The beam lamp 42 functions as a high beam lamp and a low beam lamp. The beam lamp 42 is disposed at the lower side of the range surrounded by the DRL 41. The beam lamp 42 is supported by a luminaire supporting portion 46A3 (see fig. 3) of the headlamp bracket 46. The beam lamp 42 includes a light emitting body, not shown, and a lens 42A that transmits light of the light emitting body. The light emitter of the beam lamp 42 is constituted by, for example, a light source main body not shown and a reflector not shown that reflects light of the light source main body. In the beam lamp 42, the light emitter emits light and the lens 42A appears to emit light. The light emitting unit 42B of the present embodiment is constituted by a light emitting body not shown and a lens 42A.
A pair of left and right air inlets 61A, 61B are formed around the beam lamp 42. Therefore, since the air inlets 61A, 61B are sandwiched between the DRL41 that is easily noticeable and the beam lamp 42, the air inlets 61A, 61B can be made relatively less noticeable (less noticeable). In particular, when the DRL41 and the beam lamp 42 emit light, the air inlets 61A and 61B are hole-shaped when viewed from the front, and the light is hardly reflected and is easily darkened, so that the separation shape of the DRL41 and the beam lamp 42 is easily seen. That is, the air inlets 61A, 61B are less noticeable.
The lens 42A has a pair of upper and lower lenses 42A1, 42A2. The lenses 42A1, 42A2 are formed to be laterally long. The lenses 42A1 and 42A2 have a convex shape protruding forward. In the present embodiment, the lenses 42A1 and 42A2 are inclined rearward as they go outward in the left-right direction from the left-right center. Therefore, when the traveling wind blows from the front to the lenses 42A1 and 42A2, the traveling wind is easily guided to the left and right of the lenses 42A1 and 42A2, and the traveling wind is separated from the left and right by the convex shape of the beam lamp 42, so that the traveling wind can be easily introduced into the left and right air inlets 61A and 61B of the beam lamp 42.
In particular, the beam lamp 42 is disposed at the lower side of the range surrounded by the DRL41 and is disposed in front of the vehicle body, and therefore, traveling wind can be easily taken into the air intake port 61.
The head lamp 40 of the present embodiment is constituted by a DRL41 and a beam lamp 42. The headlight 40 is disposed in front of the fork tube 34 of the front fork 14.
Fig. 5 is a sectional view taken along line V-V in fig. 4. The V-V line corresponds to the vehicle width center line of the saddle-type vehicle 10. Fig. 6 is a cross-sectional view taken along line VI-VI in fig. 4.
The side portions 46B and 46C of the headlamp bracket 46 are formed in a curved plate shape in a cross-sectional view, and curve downward as they come to the outside in the vehicle width direction. A rear bracket (second headlamp bracket) 47 having an inverted U-shape is supported by the left and right side portions 46B and 46C. The rear bracket 47 is fixed to the side portions 46B, 46C. The rear bracket 47 is fixed to the side portions 46B and 46C by fastening members 73 extending in the left-right direction (see fig. 2, 3, and the like).
The rear bracket 47 has a step portion 47A extending in the left-right direction formed at a rear lower portion. The step 47A is cut into an L-shaped groove in a side view. The bottom bridge 33 enters the step 47A from the rear downward, and the bottom bridge 33 holds the rear stay 47. Therefore, the headlight stay 46 is supported by the left and right fixing portions 46A1 above the top bridge 32, and is held by the step portion 47A below the bottom bridge 33 by the rear stay 47.
Above the beam lamp 42, there is a center portion 46A of a head lamp bracket 46 supporting the DRL41 and the beam lamp 42. In the headlamp bracket 46, the DRL41 and the beam lamp 42 are supported from above, whereby the support can be stably performed.
The open-bottom U-shape formed by the center portion 46A and the side portions 46B, 46C of the headlamp bracket 46 and the open-top U-shape formed by the rear bracket 47 are joined together, thereby forming a tubular headlamp duct (intake duct) 60. The headlight duct 60 has an air inlet 61 at a front end (see fig. 5). The headlight duct 60 has a rear opening 62 at a rear end (see fig. 6). The traveling wind flows into the headlight duct 60 from the air inlet 61 and flows out from the rear opening 62.
The headlight duct 60 is disposed between the front fork 14, that is, between the pair of left and right fork tubes 34. The headlight duct 60 is disposed between the top bridge 32 and the bottom bridge 33 in the up-down direction.
The rear opening 62 is left and right broken by the front riser 18. A pair of right and left rear ducts (second intake ducts) 66 extending in a tubular shape are disposed rearward of the rear opening 62. The left and right rear ducts 66 extend rearward along the front frames 19 on the left and right inner sides of the left and right front frames 19 in the left and right direction. Only the left rear duct 66 is illustrated in fig. 5, 6. The left rear duct 66 and the right rear duct 66 are configured to be bilaterally symmetrical.
An air inlet 67 (see fig. 6) that expands in diameter as it goes forward is formed in the front end of the rear duct 66. The intake ports 67 are disposed on the left and right outer sides of the front pillar 18, respectively. Air inlet 67 overlaps front riser 18 in side view.
The rear duct 66 extends rearward with a slight front-to-rear height. The rear end of the rear duct 66 is connected to an air cleaner box 68 above the rear duct 66. In the air cleaner box 68, traveling wind flowing in from the left and right rear ducts 66 is purified. The intake path extends from the air cleaner box 68 to the cylinder portion 24 of the power unit 12, and the intake air amount generated by the traveling wind is supplied to the cylinder portion 24 while being adjusted by the throttle valve 69.
The saddle-ride type vehicle 10 of the present embodiment is a so-called uncovered saddle-ride type vehicle 10 in which the frame 11 and the front fork 14 are not covered with a vehicle body cover. In such an uncovered saddle-type vehicle 10, it is difficult to form an air guide shape by the vehicle body cover, and therefore it is difficult to efficiently guide the traveling wind from the front side of the front fork 14 toward the vehicle frame 11 side. In addition, the headlight is easily disposed in front of the rear duct, and the headlight is easily interfered with the intake of the traveling wind.
In contrast, in the present embodiment, the air intake port 61 is formed in the front surface of the headlight 40, and the headlight duct 60 is formed by the headlight 40 and the headlight stay 46, so that the traveling wind can be efficiently guided to the rear duct 66 on the side of the vehicle frame 11.
As described above, according to the present embodiment to which the present invention is applied, as the air intake structure of the saddle-type vehicle in which the headlight duct 60 is disposed between the front forks 14, the headlight duct 60 is provided with the air intake 61 that is open to the front, the DRL41 is disposed in front of the front forks 14, and the DRL41 extends along the outer periphery of the air intake 61. Accordingly, since the DRL41 which is easily noticeable extends along the outer periphery of the air inlet 61, the air inlet 61 can be disposed in front, and the air inlet 61 is less noticeable and the traveling wind is easily taken in.
In the present embodiment, the DRL41 includes a pair of light emitting portions 41D and 41E in the vehicle width direction, and the pair of light emitting portions 41D and 41E in the vehicle width direction includes lower portions 41D3 and 41E3 which are portions disposed at least one of above and below the air intake 61 in front view. Therefore, since the DRL41 is disposed in most of the outer periphery of the air inlet 61, the air inlet 61 can be disposed in front and the air inlet 61 is less noticeable.
In the present embodiment, the left-right outer edges 61A1 and 61B1 of the air intake 61 provided at the vehicle width direction outer ends, the upper edges 61A2 and 61B2 extending from the upper ends of the left-right outer edges 61A1 and 61B1, and the lower edges 61A3 and 61B3 extending from the lower ends of the left-right outer edges 61A1 and 61B1 form at least a part of an opening shape in front view, and the DRL41 is arranged so as to extend along the left-right outer edges 61A1 and 61B1, the upper edges 61A2 and 61B2, and the lower edges 61A3 and 61B 3. Therefore, since the DRL41 is disposed in most of the outer periphery of the air inlet 61, the air inlet 61 can be disposed in front and the air inlet 61 is less noticeable.
In the present embodiment, the beam lamp 42 is positioned inside the surrounding shape of the DRL41, and the air inlet 61 is positioned outside the beam lamp 42 in the lateral direction. Therefore, the air inlet 61 is sandwiched between the DRL41 that is easily noticeable and the beam lamp 42, and therefore, the air inlet 61 can be made relatively less noticeable.
In the present embodiment, the beam lamp 42 has a convex shape protruding forward. Therefore, the traveling wind is separated in the vehicle width direction by the convex shape of the beam lamp 42, and the traveling wind can be easily taken into the vehicle width direction air inlet 61 of the beam lamp 42.
In the present embodiment, the beam lamp 42 is disposed at the lower side of the range surrounded by the DRL 41. Therefore, the traveling wind is easily taken into the intake port 61.
In the present embodiment, a headlight stay 46 for supporting the DRL41 and the beam lamp 42 is provided above the beam lamp 42. Therefore, by supporting the DRL41 and the beam lamp 42 from above, the support can be stably performed.
In the present embodiment, the intake port 61 is configured to: the width increases as the direction of the front view is toward the rear. Therefore, traveling wind deviated from the front end portion can be easily taken into the rear portion of the intake port 61.
In the present embodiment, the DRL41 is configured to: the more rearward, the greater the width. Therefore, the traveling wind is easily taken into the intake port 61.
In the present embodiment, the headlight stay 46 has a center portion 46A that is supported by the front fork 14 and supports the beam lamp 42, and the DRL41 is not disposed in the center portion 46A. Therefore, the center portion 46A can be enhanced in strength.
The above embodiment shows an embodiment to which the present invention is applied, and the present invention is not limited to the above embodiment.
In the above embodiment, the pair of light emitting portions 41D, 41E has a portion disposed below the air intake port 61 in front view, but may be disposed above the air intake port 61 instead of below the air intake port 61.
In the above embodiment, the configuration in which the pair of light emitting portions 41D, 41E in the vehicle width direction is disposed below the air intake 61 and connected therebelow is described, but the pair of light emitting portions 41D, 41E in the vehicle width direction may be separated from each other. The pair of light emitting portions 41D, 41E may be formed in a ring shape by being connected below and above the air intake 61 in front view. That is, the light emitting portion 41C having the light emitting portions 41D, 41E may appear to extend on the outer periphery of the air inlet 61 in front view, and the light emitting portion 41C may extend separately in the middle or may extend in a connected state.
In the above-described embodiment, the motorcycle 1 has been described as an example of a saddle-type vehicle, but the present invention is not limited to this, and the present invention can be applied to a saddle-type vehicle having three wheels including two front wheels and two rear wheels or a saddle-type vehicle having four or more wheels.
