Description

Technical Field

[0001] The present invention relates to a side cover.

Background Art

[0002] As a saddle-type vehicle, one having an underbone-type body frame is known (see, for example, Patent Document 1). In the saddle-type vehicle described in Patent Document 1, the portion behind the handle and in front of the seat is recessed in a concave shape in side view, and the concave portion improves the foot placement property of the occupant with respect to the ground. Further, by passing the legs through the concave portion in front of the seat, it is possible to easily get on and off the saddle-type vehicle without raising the legs high. An engine is installed below the concave portion, and when the saddle-type vehicle is running, the toes are placed on a pair of footrest steps on both sides of the engine.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the saddle-type vehicle described in Patent Document 1, a concave portion is located above the engine, and the hot air generated by the cylinder of the engine easily diffuses upward. Further, the legs of the occupant overlap the left and right sides of the engine, and there is a problem that the hot air directly hits the legs of the occupant and the perceived temperature becomes high.

[0005] In view of this point, the present invention has been made, and an object thereof is to provide a side cover that can stir the hot air around the engine and suppress the direct hit of the hot air on the occupant.

Means for Solving the Problems

[0006] One aspect of the present invention is a side cover for a saddle-type vehicle in which the engine is installed below the seat, comprising a cover portion that forms the outer surface of the vehicle body around the engine, and a winglet that protrudes outward in the vehicle width direction from the cover portion, wherein the winglet is positioned in front of the engine and is tilted in a side view, thereby solving the above problem. [Effects of the Invention]

[0007] According to one embodiment of the present invention, the winglets diffuse the airflow, and the airflow passing through the winglets disturbs the heat around the engine. Even if the rider's legs are located to the left or right of the engine, the diffusion of heat from the engine reduces the direct impact of the heat on the rider's legs. The perceived temperature of the legs near the engine decreases, improving riding comfort. [Brief explanation of the drawing]

[0009] In one embodiment of the present invention, a saddle-type vehicle has an engine mounted beneath the seat. The side cover of this saddle-type vehicle forms the outer surface of the vehicle body around the engine, and winglets protrude outward in the vehicle width direction from the cover. The winglets are positioned in front of the engine and are tilted when viewed from the side. The winglets diffuse the airflow, and the airflow passing through the winglets disturbs the hot air around the engine. Even if the rider's legs are positioned to the left or right of the engine, the diffusion of hot air from the engine reduces the direct impact of the heat on the rider's legs. The perceived temperature of the legs near the engine is reduced, improving riding comfort. [Examples]

[0010] The saddle-type vehicle of this embodiment will be described below with reference to the attached drawings. Figure 1 is a left side view of the saddle-type vehicle of this embodiment. In the following figures, arrow Fr indicates the front of the vehicle, arrow Re indicates the rear of the vehicle, arrow L indicates the left side of the vehicle, and arrow R indicates the right side of the vehicle.

[0011] As shown in Figure 1, the saddle-type vehicle 1 is constructed by mounting various components such as the engine 20 and electrical system on a body frame 10. A pair of main frames 12 extend diagonally downward and rearward from the upper part of the head pipe 11 of the body frame 10, branching to the left and right. The front half of the pair of main frames 12 forms the tank rail 13, and the rear half of the pair of main frames 12 forms the body frame 14. A pair of side frames 15 extend from the lower part of the head pipe 11, branching to the left and right, towards the pair of tank rails 13. A pair of down frames 16 extend downward from the middle of the pair of side frames 15.

[0012] A fuel tank (not shown) is placed over a pair of tank rails 13 from above. The rear of the engine 20 is supported by a pair of body frames 14, and the front of the engine 20 is supported by a pair of down frames 16. The rigidity of the entire vehicle is ensured by the engine 20 being supported by the vehicle frame 10. A pair of seat rails 17 extend rearward from the rear ends of the pair of tank rails 13, and a pair of seat pillars 18 extend diagonally upward and rearward from the lower ends of the pair of body frames 14 toward the rear ends of the pair of seat rails 17. The seat 26 is supported from below by the pair of seat rails 17 and the pair of seat pillars 18.

[0013] A front fork 31 is supported by the head pipe 11 via a steering shaft (not shown) so as to be steerable. A handle 32 is provided on the upper part of the front fork 31, and a front wheel 34 is rotatably supported on the lower part of the front fork 31. A headlamp 41 is mounted in front of the head pipe 11, and a meter unit 42 is mounted above the headlamp 41. A swing arm 35 is pivotably supported on a pair of body frames 14. The swing arm 35 extends rearward from the pair of body frames 14, and a rear wheel 36 is rotatably supported at the rear end of the swing arm 35.

[0014] In the saddle-type vehicle 1 described above, there is a concave recess between the fuel tank and the seat 26. An engine 20 is installed in front of and below the seat 26, and a pair of footrests 37 are installed on both sides of the engine 20. Because the legs of the rider 5 (see Figure 2) are close to the engine 20, the perceived temperature of the legs rises due to the heat from the engine 20, worsening riding comfort. Therefore, in this embodiment, a winglet 56 is provided on the front side cover 50 in front of the engine 20, and the winglet 56 diffuses the airflow while riding, disrupting the heat from the engine 20 and suppressing the direct impact of the heat on the legs.

[0015] Referring to FIGS. 2 and 3, the front side cover will be described. FIG. 2 is a left side view of the front part of the vehicle in this embodiment. FIG. 3 is a front view of the front part of the vehicle in this embodiment. In FIG. 2, the occupant is shown by a two-dot chain line.

[0016] As shown in FIGS. 2 and 3, a head pipe 11 is provided at the front end of the vehicle body frame 10, and a front fork 31 is supported on the head pipe 11. A headlamp 41 is supported on the front fork 31 via a lamp brace (not shown). The periphery of the headlamp 41 is covered by a lamp cover 44, and a pair of turn signal lamps 43 protrude from both side surfaces of the lamp cover 44. A handle 32 and a meter unit 42 are supported on the upper part of the front fork 31, and a front fender 33 that covers the front wheel 34 from above is supported on the lower part of the front fork 31.

[0017] The vehicle body frame 10 is covered from the outside in the vehicle width direction by a pair of front side covers (side covers) 50. Each front side cover 50 is formed by a front cover (inner cover part) 51, an upper cover (cover part) 55, a middle cover (other cover part) 61, and a lower cover 67. The front cover 51 forms the front part of the front side cover 50, and the upper cover 55, the middle cover 61, and the lower cover 67 form the side part of the front side cover 50. In addition, various fixing methods such as screwing, clip fixing, and hanging fixing are adopted for the connection of each cover.

[0018] When viewed from the front, a pair of front covers 51 are provided on both sides of the front fork 31. The pair of front covers 51 extends in the vertical direction along the front fork 31. An opening 52 for taking in the running wind is formed above the pair of front covers 51, and the running wind for cooling the engine 20 is taken into the inside of the pair of front side covers 50 from this opening 52. An upper cover 55 is attached to the outside in the vehicle width direction of the upper half of the front cover 51 when viewed from the front, and a middle cover 61 is attached to the outside in the vehicle width direction of the lower half of the front cover 51 when viewed from the front.

[0019] The pair of upper covers 55 form the outer side surface of the vehicle body above the engine 20. When viewed from the side, the front half of the pair of upper covers 55 extends obliquely upward from a position below the head pipe 11, and the rear half of the pair of upper covers 55 is a tank cover that covers the fuel tank from the outside in the vehicle width direction. The knees of the rider 5 sitting on the seat 26 are positioned at the portions of the pair of upper covers 55 corresponding to the tank covers. A pair of winglets 56 protrude outward in the vehicle width direction from the pair of upper covers 55. The pair of winglets 56 are located in front of the engine 20, and the pair of winglets 56 are inclined when viewed from the side.

[0020] In this case, the trailing edge of the pair of winglets 56 is located above the leading edge and is inclined obliquely upward. When the pair of winglets 56 receive the running wind, a pressure difference is generated between the upper and lower surfaces of the winglets 56 due to the inclination of the pair of winglets 56. The pressure on the upper surface of the pair of winglets 56 becomes high, and the pressure on the lower surface of the pair of winglets 56 becomes low, and a downforce is generated by the pressure difference between the upper and lower surfaces. The vehicle body is pushed down by the downforce of the pair of winglets 56, so that the grounding force of the front wheels 34 is increased, and the operability and running stability of the saddle-type vehicle 1 are improved.

[0021] Furthermore, the pair of winglets 56 diffuse the airflow, and the airflow diffused by the winglets 56 disturbs the hot air around the engine 20. In a side view, the pair of winglets 56 are located below the seat 26 and above the footrest 37. The rider's shins are positioned behind the pair of winglets 56, and the airflow passing through the pair of winglets 56 disturbs the hot air around the engine 20, mitigating the direct impact of the heat on the shins. The perceived temperature of the legs near the engine 20 is reduced, improving riding comfort.

[0022] In a front view, a pair of winglets 56 protrude from the outermost points in the vehicle width direction of the pair of upper covers 55. In a side view, a pair of winglets 56 are provided at the front end of the pair of upper covers 55. Specifically, a pair of winglets 56 are provided at the lower edge of the pair of upper covers 55 that are located furthest outward in the vehicle width direction of the front side covers 50, below the head pipe 11 on the front side covers 50. Because there are few obstacles in front of the pair of winglets 56, a large diffusion effect of the airflow by the pair of winglets 56 is obtained. Further details of the pair of winglets 56 will be described later.

[0023] A pair of middle covers 61 form the outer surface of the vehicle body below the pair of upper covers 55. The pair of middle covers 61 extend from the lower edge of the pair of upper covers 55 to the cylinder head 22 of the engine 20. A pair of winglet supports (support projections) 62 (see Figure 4) protrude outward in the vehicle width direction from the front end of the pair of middle covers 61. A pair of lower covers 67 are formed in a roughly Z shape in side view and, together with the pair of middle covers 61, form the outer surface of the vehicle body below the pair of upper covers 55. The upper halves of the pair of lower covers 67 are located outside the vehicle width direction of the pair of middle covers 61, and the lower halves of the pair of lower covers 67 are located in front of the engine 20.

[0024] The details of the winglet will be explained with reference to Figures 4 to 7. Figure 4 is a perspective view of the winglet of this embodiment, seen from diagonally below. Figure 5 is a cross-sectional view of the front of the vehicle body in Figure 2, cut along line AA. Figure 6 is a cross-sectional view of the front of the vehicle body in Figure 2, cut along line BB. Figure 7 is a cross-sectional view of the front of the vehicle body in Figure 6, cut along line CC.

[0025] As shown in Figures 4 and 5, an upper cover 55 is installed on the upper side edge of the front cover 51, and a middle cover 61 is installed on the lower side edge of the front cover 51. A winglet 56 protrudes outward in the vehicle width direction from the lower part of the upper cover 55, and a winglet support 62 protrudes outward in the vehicle width direction from the upper part of the middle cover 61. The winglet support 62 abuts against the lower surface of the winglet 56, and the winglet 56 is supported from below by the winglet support 62. The support rigidity of the winglet 56 is increased by the winglet support 62.

[0026] The winglet 56 is formed in a plate shape that is slightly inclined downward toward the outside in the vehicle width direction. The tip 57 of the winglet 56 on the outside in the vehicle width direction is directed downward, and the airflow is directed downward at the tip 57 of the winglet 56, creating a complex flow. In this case, the tip 57 of the winglet 56 is bent in two stages, and after being folded downward toward the outside in the vehicle width direction, it is folded back downward toward the inside in the vehicle width direction. The folded shape of the winglet 56 makes it easier for the airflow to flow from the outside in the vehicle width direction to the inside, and the airflow passing through the winglet 56 creates a roughly vortex-like flow.

[0027] Furthermore, the trailing edge 58 of the winglet 56 is directed downward from its base to its tip. In other words, the trailing edge 58 of the winglet 56 functions as a rib extending from its base to its tip, thereby increasing the rigidity of the winglet 56. In addition, the trailing edge 58 of the winglet 56 directs the airflow downward, creating an even more complex flow. In this way, as the airflow passes through the winglet 56, it is diffused in a complex manner, disturbing the hot air around the engine 20 and mitigating the direct impact of the hot air on the occupant's legs.

[0028] The front surface 63 of the winglet support 62 narrows vertically toward the outside in the vehicle width direction, and the lower surface 64 of the winglet support 62 slopes upward toward the outside in the vehicle width direction. As a result, the airflow at the base end of the winglet 56 is directed upward, creating a complex flow. In this case, since the lower surface 64 of the winglet support 62 is connected to the lower surface of the winglet 56, the airflow at the base end of the winglet 56 tends to flow from the inside in the vehicle width direction to the outside in the vehicle width direction. At the base end of the winglet 56, the airflow tends to flow toward the outside in the vehicle width direction, and at the tip 57 of the winglet 56, the airflow tends to flow toward the inside in the vehicle width direction, creating a roughly vortex-like flow.

[0029] As shown in Figures 6 and 7, the front surface 63 of the winglet support 62 widens inward in the vehicle width direction towards the rear. Airflow flows along the front surface 63 of the winglet support 62 and is guided to the tip 57 of the winglet 56. As described above, the folded shape of the tip 57 of the winglet 56 creates a vortex-like flow. The front surface 63 of the winglet support 62 is sloped downward towards the rear, and the slope of the front surface 63 becomes steeper (rising) from the outside in the vehicle width direction to the inside in the vehicle width direction. Airflow hitting the front surface 63 of the winglet support 62 is diffused more strongly towards the inside in the vehicle width direction.

[0030] As shown in Figure 5, the upper cover 55 and the middle cover 61 are fixed together on the inner side of the upper cover 55 in the vehicle width direction at a location corresponding to the winglet 56. In this case, a boss 59 protrudes inward in the vehicle width direction from the lower part of the upper cover 55, and a mounting piece 65 extends from the upper part of the middle cover 61 toward the boss 59. The mounting piece 65 of the middle cover 61 is superimposed on the protruding end face of the boss 59 of the upper cover 55 from the inner side in the vehicle width direction. A front cover 51 is provided inside the upper cover 55 and the middle cover 61, and the seating surface 53 of the front cover 51 is superimposed on the mounting piece 65 of the middle cover 61 from the inner side in the vehicle width direction.

[0031] A screw hole is formed in the boss 59 of the upper cover 55, and through holes are formed in the mounting piece 65 of the middle cover 61 and the seating surface 53 of the front cover 51, respectively, and the boss 59, mounting piece 65, and seating surface 53 are fastened together with a screw 69. At the base end of the winglet 56, the upper cover 55, middle cover 61, and front cover 51 are fixed with a common screw 69, which increases the rigidity of the base end of the winglet 56 and suppresses vibration of the winglet 56. By suppressing vibration of the winglet 56, the downforce generated by the winglet 56 is stabilized and fatigue failure of the winglet 56 is suppressed.

[0032] Here, we will explain the airflow as it passes through the winglet 56. As shown in Figures 4 and 5, when airflow enters the area below the winglet 56, some of the airflow flows along the winglet 56 and the winglet support 62. At the base end of the winglet 56, an upward flow is created from the inside in the vehicle width direction to the outside in the vehicle width direction, and at the tip 57 of the winglet 56, a downward flow is created from the outside in the vehicle width direction to the inside in the vehicle width direction. As a result, a roughly vortex-shaped flow is created behind the winglet 56 as it passes through it.

[0033] As shown in Figure 6, when airflow flows along the front surface 63 of the winglet support 62, the front surface 63 of the winglet support 62 creates an outward flow in the vehicle width direction. The airflow is guided toward the tip 57 of the winglet 56, where a downward flow is created from the outward to the inward direction in the vehicle width direction. Furthermore, as shown in Figure 7, the front surface 63 of the winglet support 62 diffuses more vigorously towards the inward direction in the vehicle width direction. In addition, at the trailing edge 58 of the winglet 56, the airflow is directed downward, causing the airflow to diffuse in a complex manner.

[0034] As the airflow passes through the winglet 56, it is diffused in a complex manner, creating a swirling flow behind the winglet 56. The shins of the occupant 5 are located behind the winglet 56, and the engine 20, a heat source, is located inside the shins of the occupant 5. The hot air around the engine 20 is disturbed by the swirling airflow, mixing with the airflow to lower the temperature and disperse the hot air over a wide area. As a result, the hot air from the engine 20 does not concentrate on the occupant 5's shins, and the perceived temperature of the shins does not become too high.

[0035] As described above, in the saddle-type vehicle 1 of this embodiment, the airflow is diffused by the winglets 56, and the hot air around the engine 20 is disturbed by the airflow that has passed through the winglets 56. Even if the legs of the occupant 5 are located to the left and right of the engine 20, the direct impact of the hot air on the occupant 5's legs is mitigated by the diffusion of the hot air from the engine 20. The perceived temperature of the legs near the engine 20 is reduced, improving riding comfort.

[0036] In this embodiment, the side cover is formed by four cover members: a front cover, an upper cover, a middle cover, and a lower cover. However, the number of cover members is not limited, and for example, the side cover may be formed by a single cover member.

[0037] Furthermore, in this embodiment, the winglets are inclined upwards at the rear when viewed from the side, but they may also be inclined downwards at the rear when viewed from the side.

[0038] Furthermore, in this embodiment, the winglets are positioned above the engine in a side view, but the winglets only need to be positioned in front of the engine.

[0039] Furthermore, in this embodiment, the winglets are located above the seat and above the footrests in a side view, but the winglets may be located below the footrests if the airflow passing through them is directed towards the engine.

[0040] Furthermore, in this embodiment, the winglets create a swirling flow of airflow while driving, but it is not necessary for a swirling flow to be created if the airflow can disturb the hot air around the engine.

[0041] Furthermore, in this embodiment, the winglet and the upper cover are formed integrally, but the winglet and the upper cover may be formed separately.

[0042] Furthermore, the winglets of this embodiment may be used not only in the saddle-type vehicle described above, but also in other types of saddle-type vehicles. It should be noted that the term "saddle-type vehicle" is not limited to all vehicles in which the driver sits straddling a seat, but also includes scooter-type vehicles in which the driver does not straddle a seat.

[0043] As described above, the first embodiment is a side cover (50) of a saddle-type vehicle (1) in which an engine (20) is installed below the seat (26), comprising a cover portion (upper cover 55) that forms the outer surface of the vehicle body around the engine, and a winglet (56) that protrudes outward in the vehicle width direction from the cover portion, the winglet being positioned in front of the engine and tilted in a side view. With this configuration, the airflow is diffused by the winglet, and the hot air around the engine is disturbed by the airflow that has passed through the winglet. Even if the rider's legs are located on the left and right sides of the engine, the direct impact of the hot air on the rider's legs is mitigated by the diffusion of the hot air from the engine. The perceived temperature of the legs near the engine is reduced, improving riding comfort.

[0044] In the second embodiment, as in the first embodiment, the winglet protrudes from the outermost part of the cover in the vehicle width direction when viewed from the front. With this configuration, there are fewer obstacles in front of the winglet, and a greater diffusion effect can be obtained from the winglet.

[0045] In the third embodiment, a footrest (37) is installed to the side of the engine, and in a side view, the winglet is located below the seat and above the footrest. This configuration mitigates the direct impact of hot air on the occupant's shins located behind the winglet.

[0046] The fourth embodiment is one of the first to third embodiments, in which the winglet is provided at the front end of the cover portion. With this configuration, there are fewer obstacles in front of the winglet, and a greater airflow diffusion effect by the winglet can be obtained.

[0047] The fifth embodiment is one of the first to fourth embodiments in which the outer tip (57) of the winglet in the vehicle width direction is directed downward. With this configuration, the airflow is directed downward at the tip of the winglet, creating a complex airflow. The airflow disrupts the hot air around the engine, mitigating the direct impact of the hot air on the occupants' legs.

[0048] The sixth embodiment is a modification of the fifth embodiment in which the outer tip of the winglet in the vehicle width direction is folded downward outward in the vehicle width direction and then folded downward inward in the vehicle width direction. With this configuration, the folded shape of the winglet makes it easier for the airflow to flow from the outer side in the vehicle width direction to the inner side, and the airflow passing through the winglet creates a roughly vortex-like flow.

[0049] The seventh aspect is one of the first to sixth aspects, in which the trailing edge (58) of the winglet is directed downward from the base to the tip. With this configuration, the trailing edge of the winglet functions as a rib, increasing the rigidity of the winglet. In addition, the trailing edge of the winglet directs the airflow downward, creating a complex flow pattern.

[0050] The eighth aspect is one of the first to seventh aspects, and includes another cover portion (middle cover 61) that forms the outer surface of the vehicle body below the cover portion, and a support projection (winglet support 62) that protrudes outward in the vehicle width direction from the other cover portion, with the winglet being supported from below by the support projection. With this configuration, the support rigidity of the winglet is increased by the support projection.

[0051] The ninth embodiment is the eighth embodiment, wherein the front surface (63) of the support projection widens inward in the vehicle width direction toward the rear. With this configuration, airflow flows along the front surface of the support projection, and the airflow is guided to the tip of the winglet and diffused.

[0052] In the tenth embodiment, the front surface of the support projection is inclined downward towards the rear, and the inclination of the front surface becomes steeper from the outside in the vehicle width direction towards the inside in the vehicle width direction. With this configuration, the airflow hitting the front surface of the support projection is diffused more strongly towards the inside in the vehicle width direction.

[0053] The eleventh embodiment is one of the eighth to tenth embodiments, in which the cover portion is fixed to other cover portions at a location corresponding to the winglet on the inner side of the cover portion in the vehicle width direction. With this configuration, the rigidity of the base end of the winglet is increased and vibration of the winglet is suppressed.

[0054] In the twelfth aspect, an inner cover portion (front cover 51) is provided inside the cover portion and other cover portions in the eleventh aspect, and the cover portion, other cover portions and inner cover portion are fixed together with a common fastening member (screw 69). With this configuration, the rigidity of the base end of the winglet is increased, and vibration of the winglet is further suppressed.

[0055] Although this embodiment has been described, other embodiments may include combinations of the above embodiment and its modifications, either entirely or partially.

[0056] Furthermore, the technology of the present invention is not limited to the embodiments described above, and may be modified, substituted, or transformed in various ways without departing from the spirit of the technical idea. Moreover, if the technical idea can be realized in a different way by advances in the technology or by other derived technologies, it may be implemented by that method. Accordingly, the claims cover all embodiments that may fall within the scope of the technical idea. [Explanation of Symbols]
