The present invention has been made in view of the above circumstances, and an object thereof is to make it possible to make a ventilation opening provided in a vehicle body cover compact in a saddle type vehicle.

Means for solving the problems

The saddle-ride type vehicle includes: an engine; a radiator disposed in front of the engine; a vehicle body cover that covers the radiator from a side; and an opening provided in the vehicle body cover for discharging the wind flowing inside the vehicle body cover to the outside, wherein the opening includes: a first opening located forward of a rear surface of the heat sink; and a second opening located rearward of the front surface of the heat sink.

In addition to the above configuration, an inlet face of the wind at the first opening may be larger than an inlet face of the wind at the second opening.

In addition to the above configuration, the first opening and the second opening may be located forward of a seat for an occupant, and the outlet surface of the wind at the first opening and the outlet surface of the wind at the second opening may extend long in the vertical direction and tilt forward such that the upper portion is located forward of the lower portion in a side view of the vehicle.

In the above configuration, the vehicle body cover may include a side wall that defines the second opening from an outer side in the vehicle width direction behind the first opening, the side wall may be inclined so as to be positioned on the outer side in the vehicle width direction as going rearward, and the wind discharged from the first opening may flow along an outer side surface of the side wall.

In the above configuration, the front portion of the side wall may define the first opening from the inside in the vehicle width direction, and the rear portion of the side wall may define the second opening from the outside in the vehicle width direction.

In the above configuration, the rear end portion of the side wall may be located on the vehicle width direction outer side than the wind outlet surface at the first opening.

In addition to the above configuration, the side wall may overlap the radiator from outside in the vehicle width direction when the vehicle is viewed in a side view.

In addition to the above configuration, the second opening may overlap the first opening when the vehicle is viewed in a rear view.

In the above configuration, the first opening may be provided in a bulging portion that bulges outward in the vehicle width direction from the vehicle body cover, an outer side surface of the bulging portion may include an inclined surface that is inclined so as to be positioned inward in the vehicle width direction as it goes downward from the first opening, and a foot placement portion on which a foot of a passenger is placed may be provided below the inclined surface.

In addition to the above configuration, a front portion of the foot placement section may be located forward of the first opening.

Effect of the utility model

The saddle-ride type vehicle includes: an engine; a radiator disposed in front of the engine; a vehicle body cover that covers the radiator from the side; and an opening provided in the vehicle body cover for discharging the wind flowing inside the vehicle body cover to the outside, the opening including: a first opening located forward of a rear surface of the heat sink; and a second opening located rearward of the front surface of the heat sink.

According to this configuration, a part of the wind flowing inside the vehicle body cover can be discharged from the first opening located forward of the rear surface of the radiator before passing through the radiator. Further, the wind passing through the radiator can be discharged from the second opening located rearward of the front surface of the radiator. Therefore, the air flowing inside the vehicle body cover can be divided into the first opening and the second opening and discharged, and the respective sizes of the first opening and the second opening can be made compact.

In addition to the above configuration, the inlet surface of the wind at the first opening may be larger than the inlet surface of the wind at the second opening.

According to this configuration, even if the amount of air inside the vehicle body cover increases, the air can be efficiently made to flow toward the inlet face of the air of the first opening, and can be efficiently discharged from the first opening.

In addition to the above-described configuration, the first opening and the second opening may be located forward of the seat for the occupant, and the outlet surface of the wind at the first opening and the outlet surface of the wind at the second opening may extend vertically long and incline forward such that the upper portion is located forward of the lower portion in a side view of the vehicle.

According to this configuration, the wind discharged from the first opening and the wind discharged from the second opening are directed upward. Therefore, the flow of the exhaust wind of the first opening and the second opening to the occupant can be suppressed.

In the above configuration, the vehicle body cover may include a side wall that defines the second opening from the outside in the vehicle width direction behind the first opening, the side wall may be inclined so as to be positioned on the outside in the vehicle width direction as the side wall moves rearward, and the wind discharged from the first opening may flow along an outer side surface of the side wall.

According to this configuration, the exhaust air from the second opening can be caused to flow outward in the vehicle width direction by the side wall that is inclined so as to be positioned outward in the vehicle width direction as it goes rearward. Further, the wind discharged from the first opening can be made to flow to the outside in the vehicle width direction along the outer side surface of the side wall. Therefore, the flow of the exhaust air from the first opening and the second opening toward the inside in the vehicle width direction can be suppressed.

In the above configuration, the front portion of the side wall may define a first opening from the inside in the vehicle width direction, and the rear portion of the side wall may define a second opening from the outside in the vehicle width direction.

According to this structure, the first opening and the second opening can be formed by the side wall with a simple configuration.

In addition to the above configuration, the rear end portion of the side wall may be located on the vehicle width direction outer side of the outlet surface of the wind at the first opening.

According to this configuration, the flow of the wind discharged from the first opening toward the inside in the vehicle width direction can be suppressed by the rear end portion of the side wall.

In addition to the above-described configuration, the side wall may overlap the radiator from the outside in the vehicle width direction when the vehicle is viewed in a side view.

According to this configuration, the wind flowing toward the vehicle width direction outer side through the radiator flows toward the vehicle width direction outer side and the rear along the side wall. Therefore, the flow of the air passing through the radiator to the first opening can be suppressed, and the air passing through the radiator can be efficiently discharged from the second opening.

According to this configuration, when the vehicle is viewed from the rear, the first opening can be hidden by the second opening, and the appearance is good.

According to this configuration, the foot placement section can be provided below the bulging section provided with the first opening. In addition, the wind discharged from the first opening can be suppressed from blowing on the feet placed on the feet placement section.

In addition to the above configuration, the front portion of the foot placement section may be located forward of the first opening.

According to this configuration, the foot placement section can be made long in the front-rear direction, the occupant can easily place the feet, and the exhaust air from the first opening is less likely to blow toward the feet.

The front portion of the side opening 80 in the outer cover 65 covers the first inlet face 71a of the inner cover 66 from the vehicle width direction outer side.

More specifically, the front edge 80a of the side opening 80 is located rearward of the inlet surface outer edge 71d of the first inlet surface 71a and forward of the inlet surface inner edge 71c of the first inlet surface 71 a. The front edge 80a is substantially parallel to the inlet face inner edge 71c and is inclined forward in a side view of the vehicle.

The side opening 80 overlaps the rear portion of the first inlet face 71a from the vehicle width direction outer side when the vehicle is viewed in side view. Therefore, when the vehicle is viewed in a side view, the rear portion of the first inlet surface 71a is visually recognized from the outside through the side opening 80.

The front edge 80a of the side opening 80 is the outlet face front edge portion 71e of the first outlet face 71 b.

The inclined wall 81 of the outer cover 65 overlaps the rear side wall 75 of the inner cover 66 from the vehicle width direction outer side. The inclined wall 81 is accommodated in the front-rear width of the rear side wall 75.

The side wall 73 is a plate-like portion formed by overlapping the rear side wall 75 and the inclined wall 81.

In the opening cover 67, a portion defining the second opening 72 from the outside in the vehicle width direction is a portion of the side wall 73.

Referring to fig. 4 and 7, the cover lower portions 56 of the left and right front side covers 37 are disposed on the vehicle width direction outer sides of the radiator 60, and cover the end portions 60c of the radiator 60 from the vehicle width direction outer sides. That is, the radiator 60 is disposed inside the left and right cover lower portions 56.

Left and right hood lower portions 56 extend to the vehicle front side of radiator 60. Front surface 60a of radiator 60 is exposed forward of the vehicle from between left and right cover lower portions 56.

The left and right inner surface covers 58 extend to the vehicle front side of the radiator 60, and cover the left and right cover lower portions 56 from the vehicle width direction inner side. The inner surface cover 58 is located inward in the vehicle width direction with respect to the inner cover 66.

Referring to fig. 4 and 7, the radiator 60 is disposed between the first opening 71 and the second opening 72 in a side view of the vehicle. At least a part of the first opening 71 is disposed at the same height position as the heat sink 60 in the vertical direction. At least a part of the second opening 72 is disposed at the same height position as the heat sink 60 in the vertical direction.

The first opening 71 and the second opening 72 are located on the vehicle width direction outer side with respect to the radiator 60.

The first opening 71 is located forward of the rear surface 60b of the radiator 60 in side view of the vehicle.

Specifically, the first inlet surface 71a of the first opening 71 is positioned forward of the radiator 60. The first outlet surface 71b of the first opening 71 is located entirely forward of the heat sink 60, but a part of the first outlet surface 71b of the first opening 71 overlaps the heat sink 60 from the side.

The second opening 72 is located rearward of the front surface 60a and the rear surface 60b of the radiator 60 in side view of the vehicle. That is, the second inlet surface 72a and the second outlet surface 72b are located rearward of the rear surface 60b of the radiator 60.

The second opening 72 overlaps the first opening 71 from behind when viewed from the rear.

The side wall 73 located forward of the second opening 72 overlaps the radiator 60 from the vehicle width direction outer side in a side view of the vehicle, and covers the radiator 60 from the outer side.

The second opening 72 and the first opening 71 are vertically elongated and inclined forward, and the vertical lengths are substantially equal. Therefore, the second opening 72 and the first opening 71 provide a uniform design feeling, and the appearance is good.

Here, the flow of wind flowing inside the front cover 37 will be described with reference to fig. 7.

As the motorcycle 1 travels, the wind W1 is introduced into the front side cowl 37 from the front.

The wind W1 flows rearward in the cover lower portion 56 of the front cover 37 and is discharged to the outside of the front cover 37 from the first opening 71.

Specifically, the wind W1 enters the first opening 71 from the first inlet surface 71a, flows rearward and outward in the vehicle width direction in the first opening 71, and is discharged outward from the first outlet surface 71 b.

Since the front portion 73a of the side wall 73 defining the first opening 71 from the vehicle width direction inner side is inclined outward and rearward in the vehicle width direction, the wind W1 flows outward and rearward in the vehicle width direction along the outer side of the front portion 73a of the side wall 73.

Then, the wind W1 flows along the rear portion 73b of the side wall 73 outward and rearward in the vehicle width direction.

The first opening 71 is inclined forward and opened upward and rearward when the vehicle is viewed in side elevation, and therefore the wind W1 is discharged upward and rearward.

Further, a part of the wind W1 introduced into the cover lower portion 56 may flow rearward toward the second opening 72 side without passing through the first opening 71.

The wind W2 heading toward the radiator 60 from the front enters the radiator 60 from the front surface 60a and flows out of the radiator 60 from the rear surface 60 b.

Since the components such as the cylinder portion 31 are present behind the radiator 60, the wind W2 blown out from the rear surface 60b tends to flow outward in the vehicle width direction.

The wind W2 flowing outward in the vehicle width direction from the rear surface 60b flows outward and rearward in the vehicle width direction along the inner side surfaces of the side walls 73, and is discharged to the outside of the front cover 37 from the second opening 72.

Specifically, the wind W2 enters the second opening 72 from the second inlet surface 72a, flows rearward in the second opening 72, and is discharged rearward and outward in the vehicle width direction from the second outlet surface 72 b.

The second opening 72 is inclined forward in side view of the vehicle and opens upward and rearward, and therefore, the wind W2 is discharged upward and rearward. In particular, when the motorcycle 1 is parked, the wind W2 is discharged upward and rearward from the second opening 72, and therefore, heat can be discharged upward and rearward from the inside of the front cover 37.

In the motorcycle 1, the wind W1 that has not passed through the radiator 60 is discharged from the first opening 71, and the wind W2 that has passed through the radiator 60 is discharged from the second opening 72. Therefore, the wind W1 and the wind W2 can be divided into the first opening 71 and the second opening 72 and discharged, and the first opening 71 and the second opening 72 can be made compact.

Since the first inlet surface 71a is larger than the second inlet surface 72a, the wind W1 can be efficiently discharged from the first opening 71. Therefore, the air resistance of the motorcycle 1 by the wind W1 can be effectively reduced.

The outlet surface inner edge 72f of the second opening 72 is positioned forward of the outlet surface outer edge 72 e. Therefore, when the vehicle is viewed in a side view, the outlet face inner edge portion 72f is hidden by the outlet face outer edge portion 72e, and the second opening 72 is less noticeable. Further, the second opening 72 is provided on the rear surface of the hood lower portion 56, and therefore, the second opening 72 is less noticeable when the vehicle is viewed in side view.

Referring to fig. 1, 5, and 7, the footrest section 50 is positioned below the inclined surface 56b of the cover lower portion 56. That is, the footrest section 50 is positioned below the first opening 71 and the second opening 72 of the cover lower portion 56.

The cover lower portion 56, the first opening 71, and the second opening 72 overlap the inclined portion 50b constituting the front portion of the foot placing portion 50 from above. The front end of the inclined portion 50b extends forward of the first opening 71.

Since the footrest section 50 extends forward to a position below the cover lower portion 56, the footrest section 50 is long in the front-rear direction. Therefore, the occupant can easily place his or her feet on the foot placing section 50.

Further, since the first opening 71 and the second opening 72 are positioned above the footrest section 50, the wind discharged from the first opening 71 and the second opening 72 is less likely to blow against the feet of the occupant resting on the footrest section 50.

Further, since the first opening 71 and the second opening 72 discharge air rearward and upward, the air discharged from the first opening 71 and the second opening 72 is less likely to be blown onto the feet and the legs of the occupant.

As described above, according to the embodiment to which the present invention is applied, the motorcycle 1 includes: a power unit 11 as an engine; a radiator 60 disposed in front of the power unit 11; a front cover 37 that covers the heat sink 60 from the side; and an opening 70 provided in the front cover 37 and discharging the wind flowing inside the front cover 37 to the outside, the opening 70 including: a first opening 71 located forward of the rear surface 60b of the heat sink 60; and a second opening 72 located rearward of the front surface 60a of the heat sink 60.

According to this configuration, a part of the wind flowing inside the front cover 37 can be discharged from the first opening 71 located forward of the rear surface 60b of the radiator 60 before passing through the radiator 60. Further, the wind passing through the radiator 60 can be discharged from the second opening 72 located rearward of the front surface 60a of the radiator 60. Therefore, the air flowing inside the front cover 37 can be divided into the first opening 71 and the second opening 72 and discharged, and the first opening 71 and the second opening 72 can be made compact in size.

The first inlet surface 71a, which is the inlet surface of the wind at the first opening 71, is larger than the second inlet surface 72a, which is the inlet surface of the wind at the second opening 72.

According to this configuration, even if the air volume inside the front cover 37 increases, the air can be efficiently made to flow toward the first inlet surface 71a of the first opening 71, and the air can be efficiently discharged from the first opening 71.

The first opening 71 and the second opening 72 are located forward of the seat 14 for the occupant, and the first outlet surface 71b, which is the outlet surface of the wind at the first opening 71, and the second outlet surface 72b, which is the outlet surface of the wind at the second opening 72, extend long in the vertical direction and tilt forward so that the upper portion is located forward of the lower portion in the side view of the vehicle.

According to this configuration, the wind discharged from the first opening 71 and the wind discharged from the second opening 72 are directed upward. Therefore, the wind discharged from the first opening 71 and the second opening 72 can be suppressed from flowing toward the occupant.

The front cover 37 includes a side wall 73 that defines a second opening 72 from the outside in the vehicle width direction behind the first opening 71, the side wall 73 is inclined so as to be positioned on the outside in the vehicle width direction as it goes toward the rear, and the wind discharged from the first opening 71 flows along the outer surface of the side wall 73.

According to this configuration, the exhaust wind from the second opening 72 can be caused to flow outward in the vehicle width direction by the side wall 73 that is inclined so as to be positioned outward in the vehicle width direction as it goes rearward. Further, the wind discharged from the first opening 71 can flow to the outside in the vehicle width direction along the outer side surface of the side wall 73. Therefore, the flow of the exhaust air from the first opening 71 and the second opening 72 toward the inside in the vehicle width direction can be suppressed. Therefore, the flow of the discharge air of the first opening 71 and the second opening 72 to the occupant can be suppressed.

The front portion 73a of the side wall 73 defines the first opening 71 from the inside in the vehicle width direction, and the rear portion 73b of the side wall 73 defines the second opening 72 from the outside in the vehicle width direction.

According to this structure, the first opening 71 and the second opening 72 can be formed by the side wall 73 with a simple configuration.

The rear end portion 73c of the side wall 73 is located further outward in the vehicle width direction than the first outlet surface 71b of the first opening 71.

According to this configuration, the flow of the wind discharged from the first opening 71 toward the inside in the vehicle width direction can be suppressed by the rear end portion 73c of the side wall 73. Therefore, the flow of the exhaust wind of the first opening 71 to the occupant can be suppressed.

The side wall 73 may overlap the radiator 60 from the outside in the vehicle width direction in a side view of the vehicle.

According to this configuration, the wind flowing outward in the vehicle width direction through the radiator 60 flows outward and rearward in the vehicle width direction along the side wall 73. Therefore, the wind passing through the radiator 60 can be suppressed from flowing to the first opening 71, and the wind passing through the radiator 60 can be efficiently discharged from the second opening 72.

Also, the second opening 72 overlaps the first opening 71 when the vehicle is viewed from the rear.

According to this configuration, when the vehicle is viewed from the rear, the first opening 71 can be hidden by the second opening 72, and the appearance is good.

The first opening 71 is provided in a bulging portion formed by the front cover 37 bulging outward in the vehicle width direction, an outer side surface of the bulging portion is provided with an inclined surface 56b, the inclined surface 56b is inclined so as to be positioned inward in the vehicle width direction as it goes downward from the first opening 71, and a foot placement portion 50 for placing feet of a passenger is provided below the inclined surface 56 b.

According to this configuration, the footrest section 50 can be provided below the bulging section provided with the first opening 71. Further, the wind discharged from the first opening 71 can be suppressed from blowing on the feet placed on the feet placement section 50.

The front portion of the foot placement section 50 is positioned forward of the first opening 71.

According to this structure, the foot placing section 50 can be made long in the front-rear direction, the occupant can easily place the feet, and the exhaust wind of the first opening 71 is less likely to blow on the feet.
