Description

The present invention relates to a saddle type vehicle.

Conventionally, saddle-ride vehicles include electrical components such as a control unit (ECU: Electronic Control Unit). Electrical components may be placed on the side of the vehicle body (for example, see Patent Document 1). Patent Document 1 discloses a configuration in which an electrical component fixing member that supports a control unit is attached to the right side of a vehicle body frame.

International Publication No. 2019/123742

However, in general, electrical components have lower durability against external forces than strength members such as the vehicle body frame, so if electrical components are placed on the side of the vehicle, they will not be able to move from the side of the vehicle in the event of a fall or side collision. easily damaged by external forces received from Therefore, in a saddle type vehicle in which electrical components are disposed on the side of the vehicle body, there is room for improvement in terms of reducing damage to the electrical components when an external force is applied to the electrical components from the side of the vehicle.

Therefore, the present invention provides a saddle-ride type vehicle that can reduce damage to electrical components.

The saddle type vehicle of the present invention includes a body frame (10), a stay (40) fixed to the body frame (10), and electrical components held by the stay (40) and arranged on the side of the vehicle body. (30), and the stay (40) includes a main body part (41) that supports the electrical component (30), a fixing part (43) coupled to the vehicle body frame (10), and the main body part (41) and a connecting part (45) that connects the fixing part (43), and the vehicle body frame (10) has a coupled part (12) to which the fixing part (43) is coupled. However, in the extending direction of the coupled portion (12), the width of the connecting portion (45) is narrower than the width of the main body portion (41).

According to the present invention, when an external force is applied to the stay, the connecting portion can be made easier to deform preferentially than the main body portion. As a result, when the electrical components receive an external force from the side of the vehicle, the connecting portion deforms and the main body wraps around the back side of the connected portion of the vehicle body frame, allowing the electrical components to escape inward in the vehicle width direction. be able to. Therefore, external force applied to the electrical components from the side of the vehicle can be released, and damage to the electrical components can be reduced.

In the saddle type vehicle described above, the connecting portion (45) may be formed in a plate shape and may be thinner than the main body portion (41).

According to the present invention, the connecting portion can be deformed more easily than the main body portion. Therefore, the above-mentioned effects can be achieved.

In the saddle type vehicle, the electrical component (30) may include a connector (30b), and the stay (40) may include a cover portion (47) that covers the connector (30b). .

According to the present invention, damage to the electrical components can be effectively reduced by covering the connector, which has relatively low durability due to exposed electrical components, with a cover.

In the saddle type vehicle described above, the electrical component (30) may be a first control unit (30) that controls electricity generated by a generator (22).

According to the present invention, among various electrical components, damage to the first control unit, which is particularly related to the power generation function and whose failure tends to affect the operation of other electrical components, can be suppressed. Therefore, it is possible to reduce the range of influence on various electrical components that occurs when the vehicle falls over, when there is a side collision, or the like.

The above saddle-ride type vehicle further includes a rear fender (5) supported by the body frame (10), and the rear fender (5) is located on the side where the electrical component (30) is arranged in the vehicle width direction. It may also integrally include a projecting portion (50) projecting outward from the vehicle body frame (10).

According to the present invention, since the rear fender receives an external force applied from the side of the vehicle when the vehicle falls down or has a side collision, the external force applied to the electrical components can be reduced.

The above-mentioned saddle type vehicle may further include another electrical component (31) arranged in line with the electrical component (30) in the longitudinal direction of the vehicle and housed in the projecting portion.

According to the present invention, when it is necessary to arrange other electrical components near an electrical component, the other electrical components can be stored using the projecting portion, thereby eliminating the need for a dedicated storage component. Further, external forces applied from the sides of the vehicle during a fall or a side collision can be dispersed to electrical components and other electrical components. Thereby, the external force applied to the electrical components from the side of the vehicle can be reduced, and damage to the electrical components can be further reduced. In addition, since other electrical components are stored in an overhang that is integrally provided with the rear fender, compared to a structure in which the storage section for storing other electrical components is directly connected to the vehicle body frame, It is possible to make it difficult for external forces applied from the other side to the other electrical components and the overhanging portion to be transmitted to the stay and the electrical components via the rear fender and the vehicle body frame. Thereby, damage to electrical components can be further reduced.

In the saddle type vehicle described above, the other electrical component (31) may be a second control unit (31) that controls the engine (21).

According to the present invention, the second control unit can be protected by the overhang in the event of an overturn or a side collision, so that the vehicle cannot be driven due to damage to the second control unit due to an overturn or a side impact. It can be suppressed.

The saddle type vehicle described above includes a harness (32) that connects the electrical component (30) and the other electrical component (31), and the other electrical component (31) is connected to the electrical component (30). The harness (32) extends from the other electrical component (31) forward toward the electrical component (30) and is fixed in front of the electrical component (30), and the harness (32) is fixed in front of the electrical component (30), and It may also be connected to (30).

If a harness connecting an electrical component and another electrical component is routed over the shortest distance (passing between the electrical component and another electrical component), one of the electrical components and the other electrical component When displaced, the other may be pulled through the harness. In contrast, according to the present invention, even if one of the electrical component and the other electrical component is displaced, the harness that connects the electrical component and the other electrical component is routed across the electrical component, so it does not flex. Therefore, it is possible to suppress the other of the electrical components and other electrical components from being pulled by the harness. Therefore, when an external force is applied to one of the electrical components and other electrical components from the side of the vehicle, it is possible to suppress the influence on the other electrical component.

The saddle type vehicle described above includes a harness (32) that connects the electrical component (30) and the other electrical component (31), and the other electrical component (31) is connected to the electrical component (30). The harness (32) extends rearward from the electrical component (30) toward the other electrical component (31) and is fixed behind the other electrical component (31). It may be connected to other electrical components (31).

If a harness connecting an electrical component and another electrical component is routed over the shortest distance (passing between the electrical component and another electrical component), one of the electrical components and the other electrical component When displaced, the other may be pulled through the harness. In contrast, according to the present invention, even if one of the electrical component and the other electrical component is displaced, the harness that connects the electrical component and the other electrical component is routed across the other electrical component, so that it does not bend. This makes it possible to prevent the other of the electrical components and other electrical components from being pulled by the harness. Therefore, when an external force is applied to one of the electrical components and other electrical components from the side of the vehicle, it is possible to suppress the influence on the other electrical component.

According to the present invention, it is possible to provide a saddle-ride type vehicle that can reduce damage to electrical components.

At its front end, the vehicle body frame 10 supports front wheels in a steerable manner via a steering mechanism including a front suspension. The vehicle body frame 10 includes a head pipe provided at the front end, a down frame extending downward from the head pipe, a pair of left and right lower frames that branch left and right from the bottom of the down frame and extend rearward, and a rear frame of each lower frame. It includes a pair of left and right rear frames 11 extending rearward and upward from the ends, and these are integrally joined by welding or the like. The rear frame 11 is a cylindrical member. The pair of rear frames 11 extend at intervals in the vehicle width direction. The pair of rear frames 11 are arranged symmetrically with respect to the width center of the vehicle. The rear frame 11 has a front portion 11f and a rear portion 11r. The front portion 11f extends rearwardly upward from the rear end of the lower frame when viewed from the side in the vehicle width direction. The rear portion 11r extends from the upper end of the front portion 11f upwardly toward the rear in the horizontal direction more gently than the front portion 11f when viewed from the side. The rear portions 11r of the pair of rear frames 11 extend substantially parallel to each other, and extend in the front-rear direction when viewed from above. Note that the rear portion 11r does not necessarily have to extend rearward and upward, and may extend horizontally, for example.

The vehicle body frame 10 supports a rear fender 5 and a storage box 6. The rear fender 5 is made of resin material. The rear fender 5 is supported by the rear part 11r of the rear frame 11. The rear fender 5 protrudes rearward in a side view and is arranged to cover the rear wheel 3 from the upper rear. The storage box 6 is arranged between a pair of rear frames 11.

Specifically, the power unit 20 is connected to a portion of the vehicle body frame 10 near the joint between the lower frame and the rear frame 11 . The power unit 20 supports the rear wheel 3 below the rear portion 11r of the rear frame 11 when viewed from the side. The power unit 20 supports an inner rear fender 24 that is closer to the rear wheel 3 than the rear fender 5 and covers the rear wheel 3 from above.

The power unit 20 includes an ACG (AC Generator) starter motor 22 in addition to an engine 21 . The ACG starter motor 22 rotates synchronously with the engine 21 and functions as a motor or a generator. That is, the ACG starter motor 22 provides starting torque to the engine 21 by being supplied with electric power from the battery, and also generates electricity using the rotational power of the engine 21. However, the ACG starter motor 22 may function as an assist motor that assists in driving the engine 21.

The motorcycle 1 includes, as electrical components, an ACG-ECU (Electronic Control Unit) 30 (first control unit) that controls electricity generated by the ACG starter motor 22, and an FI (FI) that controls fuel injection and ignition of the engine 21. Fuel Injection)-ECU31 (second control unit).

ACG-ECU 30 is electrically connected to ACG starter motor 22 via harness 32. The ACG-ECU 30 functions as a three-phase inverter when rotating the ACG starter motor 22 using battery power. The ACG-ECU 30 functions as a converter when charging the battery using the three-phase induced electromotive force generated by the ACG starter motor 22. The FI-ECU 31 is connected via a harness 32 to a fuel injection device of the engine 21, an ignition coil, and a solenoid valve of the throttle body. These ACG-ECU 30 and FI-ECU 31 are covered from the outside in the vehicle width direction by a vehicle body cover (not shown). For example, the ACG-ECU 30 and the FI-ECU 31 are arranged so as to directly face the inner surface of the vehicle body cover. In this case, the ACG-ECU 30 and FI-ECU 31 are exposed to the outside in the vehicle width direction by removing the vehicle body cover.

FIG. 2 is an enlarged perspective view of the rear part of the motorcycle shown in FIG. 1. FIG.
As shown in FIG. 2, the ACG-ECU 30 is held on the vehicle body by a stay 40, which will be described later. The ACG-ECU 30 includes a unit main body 30a that houses a CPU and the like, and a connector 30b that protrudes from the unit main body 30a. The unit main body 30a is formed into a flat rectangular parallelepiped shape. The connector 30b protrudes from the unit body 30a in a direction perpendicular to its thickness direction. The ACG-ECU 30 is disposed on the right side of the vehicle body with the thickness direction of the unit body 30a extending along the vehicle width direction. Note that the vehicle body side portion in this embodiment is a position that is closer to one side with respect to the width center of the vehicle.

The FI-ECU 31 is held on the vehicle body by a projecting portion 50, which will be described later. The FI-ECU 31 includes a unit body 31a that houses a CPU and the like, and a connector 31b that protrudes from the unit body 31a. The unit main body 31a is formed into a flat rectangular parallelepiped shape. The FI-ECU 31 is disposed on the right side of the vehicle body, with the thickness direction of the unit body 31a extending along the vehicle width direction. The FI-ECU 31 is arranged side by side with the ACG-ECU 30 in the front-rear direction. The FI-ECU 31 is arranged at the rear of the ACG-ECU 30.

As shown in FIG. 1, the ACG-ECU 30 and the FI-ECU 31 are connected to a harness 32. The harness 32 is arranged along the rear frame 11. At least a portion of the harness 32 is continuously arranged along a portion of the rear frame 11 extending from the front portion 11f to the rear portion 11r. The harness 32 is arranged from the front of the ACG-ECU 30 to above the FI-ECU 31 when viewed from the side. A portion of the harness 32 branches off from a gathering portion along the rear frame 11 in front of the ACG-ECU 30, and is connected to the connector 30b (see FIG. 2) of the ACG-ECU 30 in a loose state. The other part of the harness 32 is branched from the gathering part along the rear frame 11 and connected to the connector 31b of the FI-ECU 31. As a result, the electric wires of the harness 32 that interconnect the ACG-ECU 30 and the FI-ECU 31 are routed along the vehicle body frame 10 in the intermediate portion thereof. The harness 32 extends forward from the FI-ECU 31 toward the ACG-ECU 30, is fixed to the rear frame 11 in front of the ACG-ECU 30, and is connected to the ACG-ECU 30.

The motorcycle 1 includes a stay 40 that holds the ACG-ECU 30, a projecting portion 50 that houses the FI-ECU 31, and a cover 60 that covers the ACG-ECU 30 from below.

FIG. 3 is a right side view showing a portion of the rear frame and the stay of the embodiment.
As shown in FIGS. 2 and 3, the stay 40 is fixed to the vehicle body frame 10. As shown in FIGS. The stay 40 is made of a metal material. The stay 40 includes a main body part 41 that supports the ACG-ECU 30, a pair of fixing parts 43 coupled to the coupled part 12 of the vehicle body frame 10, and a pair of connecting parts 45 coupling the main body part 41 and the fixing part 43. , a cover part 47 that covers a part of the ACG-ECU 30 from the side opposite to the main body part 41. The main body portion 41, the fixing portion 43, and the connecting portion 45 are formed into plate shapes. In this embodiment, the main body part 41, the fixing part 43, and the connecting part 45 are integrally formed of a single plate material, and are arranged with the thickness direction along the vehicle width direction.

The main body portion 41 has a rectangular outer shape when viewed from the side. The main body portion 41 is arranged with its longitudinal direction along the extending direction of the coupled portion 12 of the vehicle body frame 10 when viewed from the side. The ACG-ECU 30 is fixed to the main body part 41. Specifically, both ends of the ACG-ECU 30 in the extending direction of the coupled portion 12 of the vehicle body frame 10 are fastened to the main body portion 41. The entire body portion 41 is located below the coupled portion 12 of the vehicle body frame 10 when viewed from the side. The main body portion 41 is made non-contact with other members on the inside in the vehicle width direction so as to be allowed to be displaced inward in the vehicle width direction. In the illustrated example, the main body portion 41 has been subjected to a lightening process, but there is no particular limitation as to whether or not the body part 41 has been subjected to a lightening process.

The fixing portion 43 is located closer to the rear frame 11 (upper side) of the vehicle body frame 10 than the main body portion 41 in side view. The fixing portion 43 overlaps the rear frame 11 when viewed from the side, and is provided at a distance from the main body portion 41. The fixing portion 43 is welded to the rear portion 11r of the rear frame 11. That is, the coupled portion 12 of the vehicle body frame 10 is the rear portion 11r of the rear frame 11. The pair of fixing portions 43 are spaced apart from each other in the extending direction of the coupled portion 12 of the vehicle body frame 10 . In the extending direction of the coupled portion 12, the width of each fixing portion 43 is narrower than the width of the entire main body portion 41. In this embodiment, the width of each fixed portion 43 is narrower than the minimum width of the main body portion 41 in the extending direction of the coupled portion 12 . Furthermore, in the extending direction of the coupled portion 12 of the vehicle body frame 10, the sum of the widths of the fixing portions 43 is smaller than the width of the entire main body portion 41. The fixing part 43 is coupled to the lower half of the coupled part 12. The lower half of the coupled portion 12 is a lower portion of the coupled portion 12 in a cross section, and is a portion whose outer surface is inclined downward relative to the horizontal direction. In this embodiment, since the rear frame 11 is a cylindrical member, the lower half of the coupled portion 12 is a portion located below the central axis of the rear frame 11 when viewed from the side.

The connecting portion 45 extends from an upper edge of the main body portion 41 that extends along the coupled portion 12 of the vehicle body frame 10 . The pair of connecting portions 45 are spaced apart from each other in the extending direction of the coupled portion 12 of the vehicle body frame 10 . The front connecting portion 45 extends along the lateral direction of the main body portion 41 with a constant width. The rear connecting portion 45 extends in the lateral direction of the main body portion 41 in a tapered manner. Each connecting portion 45 is provided inside both ends of the main body portion 41 in the extending direction of the coupled portion 12 of the vehicle body frame 10 . The upper end of each connecting portion 45 is connected to the fixed portion 43 on a one-to-one basis. In the extending direction of the coupled portion 12 of the vehicle body frame 10, the width of each connecting portion 45 is narrower than the width of the entire main body portion 41. In this embodiment, the maximum width of each connecting portion 45 is narrower than the minimum width of the main body portion 41 in the extending direction of the coupled portion 12 . Further, in the extending direction of the coupled portion 12 of the vehicle body frame 10, the sum of the maximum widths of the respective connecting portions 45 is smaller than the width of the entire main body portion 41.

The cover part 47 is arranged so as to sandwich the ACG-ECU 30, which is arranged along the main part 41, together with the main part 41. The cover part 47 is formed in a band shape, and is arranged so that the longitudinal direction of the cover part 47 runs along the longitudinal direction of the main body part 41 when viewed from the side. Both ends of the cover section 47 are fixed to the main body section 41. An intermediate portion of the cover portion 47 is spaced apart from the main body portion 41. The cover part 47 is detachably attached to the main body part 41. For example, the cover part 47 has its rear end locked to the main body part 41 and its front end fastened to the main body part 41 .

The stay 40 holds the unit main body 30a of the ACG-ECU 30 between a main body portion 41 and a cover portion 47. At this time, the ACG-ECU 30 is arranged with the thickness direction of the unit main body 30a aligned with the thickness direction of the main body portion 41 of the stay 40, and the connector 30b protruding below the unit main body 30a. The cover part 47 covers the connector 30b of the ACG-ECU 30 from three directions: front, rear, and outside in the vehicle width direction, with most of the unit body 30a of the ACG-ECU 30 exposed to the outside in the vehicle width direction. . In this way, the stay 40 is fixed to the right rear frame 11 and holds the ACG-ECU 30, thereby fixedly disposing the ACG-ECU 30 on the right side of the vehicle body. The ACG-ECU 30 held by the stay 40 has a portion in which the unit main body 30a overlaps the rear portion 11r of the rear frame 11 when viewed from the side, and a portion located below the rear portion 11r of the rear frame 11 when viewed from the side is located above. It is arranged so that it is larger than the

FIG. 4 is an enlarged perspective view of the rear part of the motorcycle shown in FIG. 1. FIG.
As shown in FIG. 4, the projecting portion 50 is provided integrally with the rear fender 5. The projecting portion 50 is made of resin and is integrally molded with the rear fender 5. The overhanging portion 50 extends from a portion of the rear fender 5 located below the rear portion 11r of the rear frame 11 in the vehicle width direction to the side where the stay 40 is arranged (that is, to the right side) from the rear portion 11r of the rear frame 11. It also extends outward in the width direction of the vehicle. The projecting portion 50 is arranged at the rear of the stay 40 when viewed from the side. The projecting portion 50 has a rectangular shape when viewed from the side, and is formed into a box shape that is open upward. The FI-ECU 31 is arranged inside the protruding portion 50. At this time, the FI-ECU 31 is arranged with the connector 31b (see FIG. 2) protruding above the unit main body 31a. The projecting portion 50 holds the FI-ECU 31 inside without using a holding member such as a rubber band.

The cover 60 is provided integrally with the rear fender 5. The cover 60 is made of resin and is integrally molded with the rear fender 5. The cover 60 protrudes from a portion of the rear fender 5 located below the rear portion 11r of the rear frame 11 in a side view toward the side where the stay 40 is disposed in the vehicle width direction. The cover 60 is arranged below the stay 40 in side view. The cover 60 is disposed in front of the overhang portion 50 and continues to the overhang portion 50. The cover 60 is formed into a box shape that is open upward. The cover 60 covers the connector 30b (see FIG. 2) of the ACG-ECU 30 from below, and supports the load of the portion of the harness 32 connected to the connector 30b from below.

As described above, the motorcycle 1 of the present embodiment includes the stay 40 fixed to the body frame 10 and the ACG-ECU 30 held by the stay 40 and disposed on the side of the vehicle body. The stay 40 includes a main body part 41 that supports the ACG-ECU 30, a fixing part 43 that is spaced apart from the main body part 41 and is coupled to the coupled part 12 of the vehicle body frame 10, and a fixing part 43 that is fixed to the main body part 41. A connecting portion 45 that connects the portion 43 to the connecting portion 43 is provided. In the extending direction of the coupled portion 12 of the vehicle body frame 10, the width of the connecting portion 45 is narrower than the width of the main body portion 41. According to this configuration, when an external force is applied to the stay 40, the main body is The connecting portion 45 can be made easier to deform preferentially than the connecting portion 41. As a result, when the ACG-ECU 30 receives an external force from the side of the vehicle, the connecting portion 45 is deformed so that the main body portion 41 wraps around the back side of the coupled portion 12 of the vehicle body frame 10, and the ACG-ECU 30 is moved into the vehicle. It can be released inward in the width direction. Therefore, external force applied to the ACG-ECU 30 from the side of the vehicle can be released, and damage to the ACG-ECU 30 can be reduced.

Furthermore, the fixing portion 43 is coupled to the lower half of the coupled portion 12 of the vehicle body frame 10. According to this configuration, compared to a configuration in which the fixing portion is coupled to the upper half of the coupled portion 12 of the vehicle body frame 10, the range in which the connecting portion 45 overlaps the vehicle body frame 10 in side view can be reduced. Therefore, it is easy to deform the connecting portion 45 so that the main body portion 41 wraps around the back side of the coupled portion 12 of the vehicle body frame 10. Therefore, it is possible to provide a configuration that easily achieves the above-mentioned effects.

Further, the main body portion 41 of the stay 40 is located below the coupled portion 12 of the vehicle body frame 10 in a side view. As a result, the ACG-ECU 30 supported by the main body 41 is placed closer to the ground than in a configuration in which the main body of the stay is located above the coupled portion of the vehicle body frame in side view. Therefore, since the distance between the grounding point of the vehicle and the ACG-ECU 30 becomes short when the vehicle falls, the moment of force applied to the ACG-ECU 30 when the vehicle falls can be reduced. Therefore, damage to the ACG-ECU 30 during a fall can be reduced.

Moreover, since the main body part 41 is made non-contact with other members inside in the vehicle width direction so that the main body part 41 can be displaced inward in the vehicle width direction, the heat dissipation of the ACG-ECU 30 can be improved. . Moreover, since the stay 40 is made of metal, the heat dissipation of the ACG-ECU 30 can be further improved. Furthermore, since the ACG-ECU 30 is covered by the vehicle body cover from the outside in the vehicle width direction, the anti-theft performance of the ACG-ECU 30 can be improved.

Further, in the extending direction of the coupled portion 12, the width of the fixing portion 43 is narrower than the width of the main body portion 41. According to this configuration, compared to a configuration in which the main body portion of the stay that supports the ACG-ECU is directly connected to the vehicle body frame, the length of the connection point in the extending direction of the connected portion 12 of the vehicle body frame 10 is shortened. By doing so, the connecting portion 45 becomes easier to deform. Thereby, when the ACG-ECU 30 receives an external force from the side of the vehicle, the connecting portion 45 is easily deformed, so that the ACG-ECU 30 can reliably escape to the inside in the vehicle width direction.
Therefore, the external force applied to the ACG-ECU 30 from the side of the vehicle can be released, and damage to the ACG-ECU 30 can be further reduced.

Further, since the stay 40 is welded to the vehicle body frame 10, heat can be easily transferred from the stay 40 to the vehicle body frame 10, and the heat dissipation of the ACG-ECU 30 can be improved. Furthermore, compared to a configuration in which the main body is directly welded to the vehicle body frame, the length of the welded portion between the stay 40 and the vehicle body frame 10 is shorter, reducing manufacturing costs by reducing component size and simplifying the welding process. can be reduced. Furthermore, since the stay 40 can be coupled to the vehicle body frame 10 without using a fixing member such as a fastening member, it is possible to suppress an increase in the number of parts and reduce manufacturing costs.

The stay 40 has a cover portion 47 that covers the connector 30b of the ACG-ECU 30. According to this configuration, damage to the ACG-ECU 30 can be effectively reduced by covering the connector 30b, which has relatively low durability due to exposed terminals as electrical components, with the cover portion 47. I can do it.

Further, in this embodiment, the electrical component held by the stay 40 is the ACG-ECU 30 that controls electricity generated by the ACG starter motor 22. According to this configuration, it is possible to suppress damage to the ACG-ECU 30, which is particularly involved in the power generation function among various electrical components and whose failure tends to affect the operation of other electrical components. Therefore, it is possible to reduce the range of influence on various electrical components that occurs when the vehicle falls over, when there is a side collision, or the like.

The motorcycle 1 further includes a rear fender 5 supported by a body frame 10. The rear fender 5 integrally has a projecting portion 50 projecting outward from the vehicle body frame 10 on the side where the ACG-ECU 30 is disposed in the vehicle width direction. According to this configuration, the rear fender 5 receives an external force applied from the side of the vehicle in the event of a fall or a side collision, so that the external force applied to the ACG-ECU 30 can be reduced.

The motorcycle 1 includes an FI-ECU 31 that is arranged in parallel with the ACG-ECU 30 in the front-rear direction and controls the engine 21. According to this configuration, when it is necessary to arrange the FI-ECU 31 near the ACG-ECU 30, the FI-ECU 31 can be stored using the projecting portion 50, so that a dedicated storage component is not required.
Further, external force applied from the side of the vehicle during a fall or a side collision can be dispersed to the ACG-ECU 30 and the FI-ECU 31. Thereby, the external force applied to the ACG-ECU 30 from the side of the vehicle can be reduced, and damage to the ACG-ECU 30 can be further reduced. Furthermore, since the FI-ECU 31 is housed in the overhang 50 that is integrally provided with the rear fender 5, the FI-ECU 31 and the rear fender 5 can be viewed from the side of the vehicle. It is possible to make it difficult for external force applied to the overhanging portion 50 to be transmitted to the stay 40 and the ACG-ECU 30 via the rear fender 5 and the vehicle body frame 10. Thereby, damage to the ACG-ECU 30 can be further reduced.

Further, in this embodiment, another electrical component housed in the overhang 50 is the FI-ECU 31 that controls the engine 21. According to this configuration, the FI-ECU 31 can be protected by the overhanging portion 50 in the event of a fall, side collision, etc., so it is possible to prevent the vehicle from becoming unable to run due to damage to the FI-ECU 31 due to a fall, side collision, etc. can. Furthermore, damage to the ACG-ECU 30 can be suppressed with priority given to damage to the FI-ECU 31. Therefore, it is possible to reduce the range of influence on various electrical components that occurs when the vehicle falls over, when there is a side collision, or the like.

The motorcycle 1 further includes a harness 32 that connects the ACG-ECU 30 and the FI-ECU 31. It extends forward from the FI-ECU 31 toward the ACG-ECU 30, is fixed to the rear frame 11 in front of the ACG-ECU 30, and is connected to the ACG-ECU 30. If the harness connecting ACG-ECU 30 and FI-ECU 31 is routed at the shortest distance (for example, when it passes between ACG-ECU 30 and FI-ECU 31), When one is displaced, the other may be pulled through the harness. On the other hand, according to the present embodiment, even if one of the ACG-ECU 30 and the FI-ECU 31 is displaced, the harness 32 connecting the ACG-ECU 30 and the FI-ECU 31 is routed across the ACG-ECU 30, so there is no slack. The other of the ACG-ECU 30 and the FI-ECU 31 can be prevented from being pulled by the harness 32. Therefore, when an external force is applied to one of the ACG-ECU 30 and the FI-ECU 31 from the side of the vehicle, it can be suppressed from affecting the other.

Note that the harness 32 may be supported by the vehicle body frame 10 so as to be rotatable around the vehicle body frame. Thereby, when the ACG-ECU 30 or the FI-ECU 31 is displaced inward in the vehicle width direction, the harness 32 can also be displaced inward in the vehicle width direction. Thereby, when an external force is applied to one of the ACG-ECU 30 and the FI-ECU 31 from the side of the vehicle, it can be suppressed from affecting the other.

Note that the thickness relationship between the main body portion 41 and the connecting portion 45 of the stay 40 is not particularly limited, but it is desirable that the thickness of the connecting portion 45 is less than or equal to the thickness of the main body portion 41. In particular, when the connecting portion 45 is thinner than the main body portion 41, the connecting portion 45 can be made to deform more easily than the main body portion 41. Therefore, the above-mentioned effects can be achieved.

Note that the present invention is not limited to the above-described embodiments described with reference to the drawings, and various modifications can be made within the technical scope thereof.
Although the embodiment described above shows an example in which the present invention is applied to a motorcycle, the scope of application of the present invention is not limited to a motorcycle. For example, the present invention can be applied to all saddle type vehicles in which a driver rides while straddling the vehicle body. That is, the present invention is applicable not only to motorcycles but also to tricycles, or four-wheeled vehicles such as buggies and ATVs (All Terrain Vehicles).

Further, the present invention may be applied to an electric vehicle equipped with a motor as a prime mover. In this case, the ECU that controls the driving motor may be used as the electrical component of the present invention. Furthermore, electrical components such as an ECU and a battery other than the ECU that controls the generator (motor) may be supported by the stay of the present invention.

Further, in the above embodiment, each of the fixing portions 43 and the connecting portions 45 of the stay 40 is provided as a pair, but the structure is not limited to this. For example, one or more fixing portions and one or more connecting portions may be provided. Further, the single fixing portion may be formed to be elongated along the extending direction of the coupled portion of the vehicle body frame, and the plurality of connecting portions may be connected to the single fixing portion. Furthermore, the plurality of connecting portions may not extend substantially parallel to each other; for example, a pair of connecting portions may extend toward each other or away from each other as they go from the main body toward the fixing portion.

Further, in the above embodiment, the stay 40 is fixed to the rear part 11r of the rear frame 11 of the vehicle body frame 10, but the stay may be fixed to the front part 11f of the rear frame 11. Furthermore, a coupled portion of the vehicle body frame to which the stay is coupled may extend along the vertical direction.

Further, in the embodiment described above, the electric wires that interconnect the ACG-ECU 30 and the FI-ECU 31 in the harness 32 are routed along the vehicle body frame 10 in the intermediate portion thereof, but the wiring shape of the harness is particularly Not limited. However, from the viewpoint of suppressing the ECU from being pulled by the harness, it is desirable that the electric wires interconnecting the ACG-ECU 30 and the FI-ECU 31 be routed so as to have some slack.

Furthermore, in the embodiment described above, the ACG-ECU 30 is moved inward in the vehicle width direction by deforming the connecting portion 45. In addition, when an external force is applied to the stay 40, the welded portion between the fixed portion 43 and the vehicle body frame 10 may be peeled off to allow the ACG-ECU 30 to escape to the inside in the vehicle width direction. Note that the method of fixing the stay and the vehicle body frame is not limited to welding, and for example, rivet fixing or the like may be applied.

Further, in the above embodiment, the harness 32 extends from the FI-ECU 31 forward toward the ACG-ECU 30, is fixed to the rear frame 11 in front of the ACG-ECU 30, and is connected to the ACG-ECU 30, but the harness 32 is not connected to the ACG-ECU 30. The electrical components are not limited to the FI-ECU 31 and ACG-ECU 30, and may be other electrical components. Furthermore, the positional relationship between the front and rear electrical components is not limited to the above embodiment. Further, the harness may extend rearward from the ACG-ECU 30 toward the FI-ECU 31, be fixed behind the FI-ECU 31, and be connected to the FI-ECU 31. Even with this configuration, since the harness connecting the ACG-ECU 30 and the FI-ECU 31 is routed across the FI-ECU 31, there is some slack. When an external force is applied to one side of the ECU 31 from the side of the vehicle, it can be suppressed from affecting the other side.

In addition, it is possible to appropriately replace the components in the above-described embodiments with well-known components without departing from the spirit of the present invention.
