By the way, in a body cover or the like that is compactly formed in order to obtain a light appearance, hot air from the radiator may pass between the body frame and the body cover and be diffused toward the occupant.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a body cover capable of protecting an occupant from hot air flowing backward from a radiator.

A body cover according to one aspect of the present invention is a body cover for a straddle-type vehicle having a radiator disposed in a front portion of the vehicle body, and includes a base body cover that covers the radiator from the side. The above problem is solved by forming an opening that guides the running wind from the outside to the rear space of the radiator.

According to the body cover of one aspect of the present invention, the running wind is taken in from the outside to the inside of the base body cover through the opening. Running wind is led to the rear space of the radiator through the opening, and the running wind joins the hot air flowing rearward from the radiator from the outside in the left-right direction. The running wind pushes the flow of hot air inward in the vehicle width direction, thereby suppressing the diffusion of the hot air in the left-right direction. Therefore, the legs of the occupant positioned on the outer side in the left-right direction of the vehicle body are effectively protected from the hot air from the radiator.

A body cover according to one aspect of the present invention is attached to a front portion of a vehicle body of a straddle-type vehicle in which a radiator is arranged. The body cover laterally covers the radiator with the base body cover. The base body cover is formed with an opening that guides the running wind from the outside of the base body cover to the rear space of the radiator, and the running wind is taken in from the outside to the inside of the base body cover through the opening. Running wind is led to the rear space of the radiator through the opening, and the running wind joins the hot air flowing rearward from the radiator from the outside in the left-right direction. The running wind pushes the flow of hot air inward in the vehicle width direction, thereby suppressing the diffusion of the hot air in the left-right direction. Therefore, the legs of the occupant positioned on the outer side in the left-right direction of the vehicle body are effectively protected from the hot air from the radiator.

A straddle-type vehicle to which the body cover of this embodiment is applied will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a vehicle front portion of a straddle-type vehicle of this embodiment. In the following figures, an arrow FR indicates the front of the vehicle, an arrow RE indicates the rear of the vehicle, an arrow L indicates the left of the vehicle, and an arrow R indicates the right of the vehicle.

As shown in FIG. 1, the straddle-type vehicle 1 is configured by mounting various parts such as an engine 16 and an electrical system on a twin-spar vehicle body frame 10 formed by aluminum casting. The vehicle body frame 10 has a pair of main frames 12 that branch left and right from the head pipe 11 and extend rearward, and a pair of down frames 13 that branch left and right from the head pipe 11 and extend downward. A pair of main frames 12 support the rear portion of the engine 16 , and a pair of down frames 13 support the front portion of the engine 16 . By supporting the engine 16 on the body frame 10, the rigidity of the entire vehicle is ensured.

A front portion of the main frame 12 serves as a tank rail, and a fuel tank 17 is arranged on the tank rail. A rear portion of the main frame 12 is a body frame, and a seat rail 14 and a backstay 15 extend rearward from the upper portion of the body frame. A rider seat 18 is arranged on the seat rails 14 . A pair of front forks 21 are steerably supported by the head pipe 11 via a steering shaft (not shown). A front wheel 22 is rotatably supported by the lower portion of the front fork 21 , and the upper portion of the front wheel 22 is covered by a front fender 23 .

A radiator 24 is arranged below the head pipe 11 and in front of the cylinder head of the engine 16 . The radiator 24 is provided with a radiator core having a large number of thin tubes or radiating fins. Heat exchange is performed between the coolant flowing through the radiator core and the running wind blown against the radiator core. A headlamp unit 25 is provided in front of the head pipe 11 . The headlamp unit 25 is formed vertically, and two light emitting portions are arranged vertically. A headlamp cover 26 is attached around the headlamp unit 25 .

A pair of body covers 30 are attached to the straddle-type vehicle 1 to cover the radiator 24 from the left and right sides. In the compact body cover 30 as in the present embodiment, the hot air diffused in the lateral direction from the back surface of the radiator 24 is diverted laterally outward from the legs of the occupant, thereby protecting the leg parts of the occupant from the hot air of the radiator 24. difficult. Therefore, in the body cover 30 of this embodiment, an opening 36 is formed to take in the traveling wind from the outside of the body cover 30 to the rear space of the radiator 24. Diffusion of the hot air in the left and right direction is suppressed by merging with .

The detailed configuration of the body cover will be described below with reference to FIGS. 2 to 4. FIG. FIG. 2 is a left side view of the vehicle front portion of this embodiment. FIG. 3 is a left side view of the vehicle front portion of the present embodiment with a part of the body cover removed. FIG. 4 is a front view of the vehicle front portion of this embodiment.

As shown in FIGS. 2 to 4 , the body cover 30 is arranged behind the headlamp cover 26 and together with the headlamp cover 26 forms the vehicle front exterior of the straddle-type vehicle 1 . The body cover 30 has a base body cover 31 fixed to the front portion of the vehicle body frame 10, an upper body cover 61 and an outer body cover 51 outside the base body cover 31, and an inner body cover 65 inside the base body cover 31. . An outer body cover 51 is arranged from an intermediate portion to a lower portion of the outer surface of the base body cover 31 in the height direction, and an upper body cover 61 is arranged above the outer surface of the base body cover 31 .

The base body cover 31 laterally covers the body frame 10 (main frame 12 ) above the front wheels 22 and laterally covers the radiator 24 behind the front wheels 22 . The base body cover 31 has an upper half portion 32 with a small lateral width and a lower half portion 33 with a large lateral width. The outer surface of the lower half portion 33 protrudes laterally outward from the outer surface of the base body cover 31, that is, the outer surface of the upper half portion 32, to form a stepped surface 34 (see FIG. 4 in particular). there is The stepped surface 34 extends obliquely upward rearward from the front edge of the base body cover 31, and the base body cover 31 is divided into an upper half portion 32 and a lower half portion 33 with the stepped surface 34 as a boundary.

The front edge of the stepped surface 34 is positioned above the upper end of the front wheel 22 . A longitudinal groove 35 is formed by partially notching an intermediate position in the extending direction of the step surface 34 . The longitudinal groove 35 extends toward an opening 36 of the lower half 33, which will be described later. A stepped surface 34 is divided into a front half portion and a rear half portion with a longitudinal groove 35 interposed therebetween, and an elongated hole 37 is formed along the stepped surface 34 above the front half portion of the stepped surface 34 so that the rear half portion of the stepped surface 34 is formed. A projecting portion 38 is formed along the step surface 34 on the upper side. A plate-like portion 52 of an outer body cover 51 , which will be described later, is attached to the elongated hole 37 , and the upper surface of the projecting portion 38 is formed so as to be continuous with the upper surface of the plate-like portion 52 .

A lower half portion 33 of the base body cover 31 is formed with an opening 36 having a triangular shape in a side view below the step surface 34 . The opening 36 connects the inner side and the outer side of the base body cover 31 on the side of the radiator 24 and in front of the main frame 12 . Although the details will be described later, running wind is guided to the opening 36 through the vertical groove 35 and taken into the inside of the base body cover 31 . The front edge of the opening 36 is located inside the rear edge in the left-right direction, and the rear edge of the opening 36 is formed with a wall surface 39 (see FIG. 6) having a large width in the left-right direction. When the running wind hits the wall surface 39 at the rear edge of the opening 36 from the front, the running wind is taken inside the base body cover 31 through the opening 36 .

A lower front surface 41 is formed in such a manner that the front surface of the lower half portion 33 is wider than the front surface of the upper half portion 32 in the left-right direction when viewed from the front. The lower front surface 41 is formed by a front portion facing the front and a slope portion facing obliquely forward. The lower front surface 41 is recessed below the step surface 34, and protrudes forward from the recess 42 toward the front edge of the step surface 34 (see FIG. 3 in particular). Since the slope from the lower front surface 41 to the stepped surface 34 is steep, even if the running wind blows on the muddy water received by the lower front surface 41, it is difficult for the muddy water to get over the front edge of the stepped surface 34.例文帳に追加

A lower outer surface 43 of the base body cover 31 below the stepped surface 34 protrudes laterally outward toward the side edge of the stepped surface 34 (see FIG. 4 in particular). Even if the running wind blows on the muddy water adhering to the lower outer surface 43, the muddy water does not easily get over the side edge of the stepped surface 34.例文帳に追加In the front part of the base body cover 31, the front edge and the side edge of the stepped surface 34 protrude outward, making it difficult for muddy water to flow upward from the stepped surface 34, thereby suppressing muddy water from adhering to the occupant. The lower half portion 33 of the base body cover 31 partially overlaps the rear portion of the front wheel 22 when viewed from the side. A shield plate 44 (see FIG. 6) protrudes from the inner surface of the lower half portion 33 toward the main frame 12 . Due to this shielding plate 44, even if water or mud enters the inside of the opening 36, it will be difficult for it to enter the inside of the vehicle such as the suction port of an air cleaner (not shown) on the rear upper side.

Above the elongated hole 37 and the projecting portion 38 of the base body cover 31, the outer surface of the upper half portion 32 bulges outward in the left-right direction to form a bulging portion 45. As shown in FIG. The bulging portion 45 extends obliquely upward rearward from the front edge of the base body cover 31, and has a plurality of openings formed therein. A lateral groove 46 is formed in the upper edge of the upper half portion 32 so that the outer surface of the upper half portion 32 is recessed inward in the left-right direction and along the bulging portion 45 . An upper body cover 61 is attached to the outer surface of the bulging portion 45 . The upper body cover 61 extends obliquely upward rearward from the front edge of the base body cover 31 so as to cover the entire bulging portion 45 from the outside.

The outer body cover 51 is attached to the outside of the base body cover 31 below the upper body cover 61 . The outer body cover 51 is formed with an eave-like plate-like portion 52 that covers the stepped surface 34 of the base body cover 31 from above, and a rear cover portion 54 that continues behind the plate-like portion 52 via a connecting portion 53 . The plate-like portion 52 is attached to the elongated hole 37 of the base body cover 31 and extends forward and backward above the step surface 34 . The front edge of the plate-like portion 52 is positioned forward of the front edge of the stepped surface 34, and the muddy water splashed up by the front wheel 22 is received in a wide range by the eave-like plate-like portion 52.例文帳に追加

The plate-like portion 52 slopes downward outward in the left-right direction from the outer surface of the base body cover 31 , and a downwardly bent return portion 55 is formed on the outer side edge in the left-right direction of the plate-like portion 52 . A gap is provided between the inner surface of the return portion 55 and the laterally outer side edge of the step surface 34, and the return portion 55 extends below the side edge of the step surface 34 (see FIG. 4 in particular). The muddy water received by the plate-like part 52 easily flows down from the return part 55 to the lower part of the stepped surface 34, and the muddy water is less likely to go upward than the plate-like part 52, thereby suppressing adhesion of the muddy water to the occupant. Although the return portion 55 is formed in the front half portion of the plate-like portion 52 , the return portion 55 may be formed entirely along the longitudinal direction of the plate-like portion 52 .

The stepped surface 34 and the eave-like plate-like portion 52 form a path for running wind. The front edge of the stepped surface 34 and the front edge of the plate-like portion 52 form an entrance of the running wind, and the running wind enters the entrance of the running wind from the front. As described above, there is a gap between the inner surface of the return portion 55 and the stepped surface 34, and the running wind enters the gap. These running winds are rectified inside the plate-like portion 52 to reduce the running resistance due to the running winds. In this manner, the step surface 34 and the plate-like portion 52 not only receive muddy water splashed up from the front wheel 22, but also form a path for running wind that can reduce running resistance in the body cover 30.例文帳に追加

A rear portion of the plate-like portion 52 is positioned above the longitudinal groove 35 , and a connecting portion 53 is provided at the rear portion of the plate-like portion 52 . The connecting portion 53 is formed with an inner wall surface 56 (see FIG. 6) inclined inward in the left-right direction toward the rear. Guided by 35. A rear cover portion 54 is provided below the connecting portion 53 . The rear cover portion 54 covers the outside of the base body cover 31 by extending in the front-rear and up-and-down directions. A portion of the rear cover portion 54 overlaps the vertical grooves 35 and the openings 36 in a side view.

The inner body cover 65 is attached inside the base body cover 31 along the front edge of the base body cover 31 . A lower portion of the inner body cover 65 is formed along the lower front surface 41 of the base body cover 31 . The lower part of the inner body cover 65 is sloped obliquely forward, and receives water droplets from the front together with the lower front surface 41 of the base body cover 31 . The fixing method of the base body cover 31, the inner body cover 65, the outer body cover 51, and the upper body cover 61 is not particularly limited.

With reference to FIGS. 5 to 8, the path of the running wind in the body cover will be described. FIG. 5 is a partially cut side view of the body cover of this embodiment. FIG. 6 is a cross-sectional view of the body cover of FIG. 2 taken along line AA. FIG. 7 is a cross-sectional view of the body cover of FIG. 2 taken along line BB. FIG. 8 is a sectional view of the body cover of FIG. 2 taken along line CC.

As shown in FIGS. 5 and 6, the stepped surface 34 of the base body cover 31 and the plate-like portion 52 of the outer body cover 51 form a path for running wind. A longitudinal groove 35 is formed in the base body cover 31 by notching the laterally outer side edge of the stepped surface 34 in a concave shape. An inner wall surface 56 of the connecting portion 53 is positioned outside the longitudinal groove 35 in the left-right direction. Further, the base body cover 31 is formed with an opening 36 below the step surface 34 connecting the inner side and the outer side of the base body cover 31 . The upper end of the vertical groove 35 continues to the stepped surface 34 and the lower end of the vertical groove 35 extends to the opening 36 .

As viewed from the side, the opening 36 is positioned below the upper end of the radiator 24 and on the rear side of the radiator 24 (see FIG. 3 in particular). That is, an opening 36 is formed in the base body cover 31 so as to expose the rear space of the radiator 24 . Since the radiator 24 is curved rearward in this embodiment, the rear surface of the radiator 24 is exposed through the opening 36 . A wall surface 39 facing forward of the vehicle body is formed at the rear edge of the opening 36 , and the wall surface 39 spreads outward in the left-right direction from the front edge of the opening 36 . As described above, the vertical grooves 35 and the openings 36 are partially covered with the rear cover portion 54 from the outside in the left-right direction.

As shown by an arrow F1, when the body cover 30 is blown from the front, the wind flows rearward between the stepped surface 34 and the plate-like portion 52 . Further, as indicated by arrow F2, the running wind also enters through the gap between the side edge of the stepped surface 34 and the return portion 55, and flows rearward between the plate-like portions 52 of the stepped surface 34. As indicated by arrow F3, the running wind is guided toward the vertical groove 35 by the inner wall surface 56 of the connecting portion 53, and flows into the opening 36 through the vertical groove 35. At this time, since the longitudinal groove 35 is partially covered with the rear cover portion 54 from the side, the running wind can easily flow into the opening 36 .

As shown in FIG. 7, the outer surface of the base body cover 31 inclines inward in the left-right direction toward the front edge of the opening 36 in a horizontal cross-sectional view. Since the wall surface 39 does not exist on the extension of the slope of the base body cover 31 , the running wind indicated by the arrow F4 flows directly into the opening 36 from the slope of the base body cover 31 . As shown in FIG. 8, the outer surface of the base body cover 31 inclines outward in the left-right direction toward the front edge of the opening 36 in a horizontal cross-sectional view. Since the wall surface 39 exists on the extension of the slope of the base body cover 31 , the running wind along the base body cover 31 indicated by the arrow F 5 hits the wall surface 39 and flows into the opening 36 .

At this time, as shown in FIG. 6 , a shielding plate 44 is formed on the base body cover 31 to partition the gap between the base body cover 31 and the main frame 12 . The inner edge of the shielding plate 44 extends back and forth along the outer surface of the main frame 12 , and the shielding plate 44 partitions the gap between the base body cover 31 and the main frame 12 . Also, the shielding plate 44 is positioned above the opening 36 . Therefore, the running wind indicated by arrows F3-F5, for example, does not flow toward the gap between the base body cover 31 and the main frame 12 from the opening 36, but tends to flow toward the rear space of the radiator 24 inside the main frame 12.

As indicated by arrow F6 in FIGS. 7 and 8, hot air is flowing rearward from the back surface of the radiator core of the radiator 24 . Hot air is forced into the rear space of the radiator 24 from the outside in the left-right direction by the running wind that flows into the space behind the radiator 24 through the opening 36 . Diffusion of the hot air in the left-right direction is suppressed by running air, and the hot air is less likely to pass through the gap between the main frame 12 and the body cover 30 toward the legs of the occupant. In this way, even with the compact body cover 30, the diffusion of the hot air from the radiator 24 is suppressed, thereby protecting the legs of the occupant. Also, the temperature of the hot air is lowered by the outside air.

As described above, according to the present embodiment, running wind is taken in from the outside to the inside of the base body cover 31 through the opening 36 . The running wind is led to the rear space of the radiator 24 through the opening 36, and the running wind joins the hot air flowing rearward from the radiator 24 from the outside in the left-right direction. The running wind pushes the flow of hot air inward in the vehicle width direction, thereby suppressing the diffusion of the hot air in the left-right direction. Therefore, the legs of the occupant positioned on the outer side in the left-right direction of the vehicle body are effectively protected from the hot air from the radiator 24 .

Although the body cover includes the base body cover, the upper body cover, the outer body cover, and the inner body cover in this embodiment, the body cover may include at least the base body cover.

In this embodiment, the stepped surface of the base body cover and the plate-shaped portion of the outer body cover form a passageway for air flow. .

In this embodiment, the outer body cover is formed by connecting the plate-like portion and the rear cover portion with the connecting portion, but the outer shape of the outer body cover is not particularly limited.

In this embodiment, the base body cover has an opening below the upper end of the radiator and behind the radiator when viewed from the side, but the position of the opening is not particularly limited. The opening may be formed so as to guide the running wind from the outside of the base body cover to the rear space of the radiator.

Further, in this embodiment, a wall surface facing forward of the vehicle body is formed at the rear edge of the opening of the base body cover, and the shielding plate is formed on the base body cover. However, the wall surface and the shielding plate are not formed on the base body cover. may

Further, in this embodiment, the space behind the radiator indicates the space between the radiator and the engine, but it may be a space where hot air is generated from the radiator inside the pair of body covers.

The straddle-type vehicle is not limited to vehicles in general in which the occupant sits astride the seat, but also includes small scooter-type vehicles in which the occupant does not sit astride the seat.

As described above, the body cover (30) of this embodiment is a body cover for a straddle-type vehicle (1) in which the radiator (24) is arranged in the front part of the vehicle body, and is a base body cover (31) that covers the radiator from the sides. The base body cover is formed with an opening (36) that guides the running wind from the outside of the base body cover to the rear space of the radiator. According to this configuration, running wind is taken in from the outside to the inside of the base body cover through the opening. Running wind is led to the rear space of the radiator through the opening, and the running wind joins the hot air flowing rearward from the radiator from the outside in the left-right direction. The running wind pushes the flow of hot air inward in the vehicle width direction, thereby suppressing the diffusion of the hot air in the left-right direction. Therefore, the legs of the occupant positioned on the outer side in the left-right direction of the vehicle body are effectively protected from the hot air from the radiator.

In the body cover of this embodiment, the base body cover is formed with an opening that exposes the rear space of the radiator in a side view. According to this configuration, the traveling air is directly guided to the rear space of the radiator, and the diffusion of the hot air to the outside in the left-right direction is effectively suppressed.

In the body cover of this embodiment, the base body cover has a wall surface (39) facing forward of the vehicle body at the rear edge of the opening, and the wall surface extends laterally outward from the front edge of the opening. According to this configuration, since the running wind hits the wall surface of the rear edge of the opening from the front, the running wind is guided from the opening to the rear space of the radiator, thereby effectively suppressing the diffusion of the hot wind outward in the left-right direction. .

In the body cover of this embodiment, the base body cover covers the main frame (12) from the sides, and the base body cover is formed with a shielding plate (44) that partitions the gap between the base body cover and the main frame. According to this configuration, the shielding plate makes it difficult for the running wind to flow into the gap between the base body cover and the main frame, and makes it easier for the running wind to flow into the inside of the base body cover through the opening.

The body cover of this embodiment includes an outer body cover (51) attached to the outside of the base body cover, and a portion of the outer body cover overlaps the opening when viewed from the side. According to this configuration, the opening is partially covered from the side by a part of the outer body cover, and the running wind is efficiently taken into the inside of the base body cover.

Although the present embodiment has been described, another embodiment may be a combination of the above embodiments and modifications in whole or in part.

Also, the technology of the present invention is not limited to the above-described embodiments, and may be variously changed, replaced, and modified without departing from the spirit of the technical idea. Furthermore, if the technical idea can be realized in another way by advancement of technology or another derived technology, the method may be used for implementation. Therefore, the claims cover all implementations that may fall within the scope of the technical concept.
