Technical Field

The utility model relates to an electrical component configuration structure.

Background

Conventionally, a straddle-type vehicle is known which includes an air cleaner coupled to a main frame and an Electronic Control Unit (ECU) fixed to an outer surface of the air cleaner on one side in a vehicle width direction and controlling an Alternator (ACG) starter (see, for example, japanese patent No. 6695921). The ACG starter is disposed on the same lateral side of the vehicle as the ECU. The ACG and the ECU are disposed in front and rear of each other with a main frame interposed therebetween. And the ECU is electrically connected with the ACG starter through a wire harness. The harness extends from the ECU to the ACG starter via the mating surface of the crankcase and the side cover.

However, when the harness connected to the ECU and the ACG starter vibrates due to external factors such as vehicle vibration, the harness may come into contact with peripheral members such as the crankcase and the side cover.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an in the electrical installation spare configuration structure who has been connected pencil and the control unit, do not increase the condition that the part number just avoided pencil and peripheral part butt.

As a solution to the above problem, the present invention has the following configuration.

(1) The utility model discloses an electrical installation spare configuration structure of scheme possesses: a frame 20; a drive device 11; an air cleaner 40 connected to the frame 20 and purifying the outside air supplied to the driving device 11; a control unit 52 provided to an outer surface 80a of one side of the air cleaner 40 and fixed at least one fixing point P1; and a wire harness 142 connected to the control unit 52, wherein the wire harness 142 overlaps with the at least one fixing point P1 in a side view.

Here, the fixed point P1 is a central position of a portion where the control unit 52 is fixed in a side view.

(2) In the electrical component arrangement structure described in the above (1), the wire harness 142 may be fixed to both the outside of one direction side and the outside of the other direction side connected to the control unit 52 with reference to a portion 142a overlapping with the fixing point P1 in a side view.

(3) In the electrical component arrangement structure described in (1) or (2), the frame 20 may be a framework of a vehicle, and the control unit 52 may be provided on an outer surface 80a of the air cleaner 40 on one side in the vehicle width direction and may overlap at least a part 281 of the air cleaner 40 as viewed from the front of the vehicle.

(4) In the electrical component arrangement structure described in the above (3), the wire harness 142 may be arranged at a position outside the at least one fixing point P1 in the vehicle width direction.

(5) In the electrical component arrangement structure described in (3) or (4), a part of the control unit 52 may be fixed via a bracket 100 at a position not overlapping with the air cleaner 40 in a vehicle side view, and the at least one fixing point P1 may be arranged at a position not overlapping with the air cleaner 40 in a vehicle side view.

(6) In the electrical component arrangement structure described in (5) above, at least one of the fixing points PA and PB fixed to both outer sides of one direction side and the other direction side connected to the wire harness 142 and the at least one fixing point P1 may be provided in the bracket 100.

According to the electrical component arrangement structure described in the above (1) of the present invention, the electrical component arrangement structure includes the frame, the driving device, the air cleaner connected to the frame and purifying the outside air supplied to the driving device, the control unit provided on the outer surface of one side of the air cleaner and fixed at least one fixing point, and the wire harness connected to the control unit, and the wire harness overlaps with at least one fixing point in a side view, thereby achieving the following effects.

For example, if the wire harness does not overlap the fixed point of the control unit in a side view, when the wire harness vibrates due to external factors such as vehicle vibration, the wire harness is likely to come into contact with a peripheral member located on the vehicle width direction inner side of the fixed point. In this case, in order to avoid the wire harness from coming into contact with the peripheral component, a fixing member for fixing the wire harness needs to be newly provided. In contrast, according to the present configuration, since the wire harness overlaps at least one fixed point of the control unit in a side view, even if the wire harness vibrates due to external factors such as vehicle vibration, the wire harness is restricted from moving inward in the vehicle width direction by the fixed point, and therefore, the wire harness can be prevented from coming into contact with a peripheral member located inward in the vehicle width direction from the fixed point. Further, a fixing member for fixing the wire harness does not need to be newly provided. Therefore, the wire harness can be prevented from coming into contact with the peripheral member without increasing the number of components. Further, the harness can be compactly arranged as compared with a case where the harness does not overlap with a fixed point of the control unit in a side view.

According to the electrical component arrangement structure of the present invention described in (2), the wire harness is fixed to both the outside of the one direction side and the outside of the other direction side connected to the control unit with reference to the portion overlapping with the fixed point in side view, and the following effects are obtained.

The occurrence of vibration of the wire harness due to an external factor can be suppressed. This can avoid the wire harness from coming into contact with peripheral members around the fixing point. Therefore, the vibration of the wire harness can be suppressed, and the wire harness can be prevented from abutting against the peripheral member.

Further, the vibration of the wire harness can be suppressed more effectively than in the case where the wire harness is fixed only on the one side connected to the control unit with reference to the portion overlapping the fixed point in the side view. In addition, when the fixed portions of the wire harness on both outer sides with respect to the portion overlapping the fixed point in the side view are disposed in the vicinity of the control unit, the wire harness can be compactly disposed by effectively utilizing the space in the vicinity of the control unit.

According to the electrical component arrangement structure of the present invention described in the above (3), the frame is a framework of the vehicle, and the control unit is provided on the outer surface of the air cleaner on one side in the vehicle width direction, and overlaps with at least a part of the air cleaner when viewed in front of the vehicle, thereby achieving the following effects.

For example, if the control unit is provided on the outer surface of the air cleaner on one side in the vehicle width direction and is arranged at a position not overlapping the air cleaner as viewed from the front of the vehicle, the capacity of the air cleaner may be limited due to the presence of the control unit. In contrast, according to the present configuration, the control unit overlaps at least a part of the air cleaner as viewed from the front of the vehicle, and thus the capacity of the air cleaner can be secured at the portion overlapping the control unit as viewed from the front of the vehicle. Therefore, the control unit can be disposed on the outer surface of the air cleaner on one side in the vehicle width direction, and the capacity of the air cleaner can be secured.

According to the electrical component arrangement structure of the present invention described in the above (4), the wire harness is arranged at the position outside the at least one fixed point in the vehicle width direction, thereby achieving the following effects.

Since the wire harness can be arranged after the control unit is fixed to the vehicle, the assembling property can be improved with a simple structure. Further, in the case where a cover member such as a side cover is provided, when the wire harness is arranged at a position outside the fixed point in the vehicle width direction, the wire harness is easily covered by the cover member. Therefore, compactness and appearance can be improved without enlarging the cover member.

According to the electrical component arrangement structure of the present invention described in (5), a part of the control unit is fixed at a position not overlapping with the air cleaner in the vehicle side view observation through the bracket, and at least one of the fixing points is arranged at a position not overlapping with the air cleaner in the vehicle side view observation, thereby achieving the following effects.

In the air cleaner, the bracket is configured to be able to easily escape heat of the control unit, compared to a case where the control unit and the fixed point are all configured at a position overlapping with the air cleaner in a vehicle side view. Further, when at least one of the fixing points is disposed in the vicinity of the air cleaner in a side view of the vehicle, the wire harness can be disposed by effectively utilizing the space in the vicinity of the air cleaner.

According to the electrical component arrangement structure of the present invention described in the above (6), at least one of the fixing points PA and PB fixed to both outer sides of one direction side and the other direction side connected to the wire harness and at least one of the fixing points P1 are provided in the bracket, thereby achieving the following effects.

Since at least one of the fixing points PA and PB and at least one of the fixing points P1 are provided on the same bracket, it is possible to assemble the vehicle body while securing the positional relationship of at least one of the fixing points PA and PB and at least one of the fixing points P1 without providing a member for guiding the side of the wire harness. Therefore, the assembling property can be improved without increasing the number of the components.

A fixing point P1 of the front connecting portion 121 of the ACG-ECU52 (hereinafter also referred to as "front fixing point P1") is arranged between the front end side (bolt 98) of the front center extending portion 84 of the air cleaner 40 and the front end side of the front lower extending portion 85 in a vehicle side view. The front fixing point P1 of the ACG-ECU52 is disposed at a position not overlapping the air cleaner 40 in a vehicle side view.

On the other hand, a fixing point P2 of the rear connecting portion 122 of the ACG-ECU52 (hereinafter also referred to as "rear fixing point P2") is disposed at a position overlapping the air cleaner 40 in a vehicle side view. The rear fixing point P2 of the ACG-ECU52 is disposed in the vicinity of the front of the lower side extension 83 in a vehicle side view.

In the present embodiment, the front fixing point P1 and the rear fixing point P2 are provided to the bracket 100. As shown in fig. 7, when attention is paid to bracket 100 as viewed from the side of the vehicle, front fixing point P1 corresponds to the axial center position of bolt 131 provided at front coupling portion 105 of bracket 100, and rear fixing point P2 corresponds to the axial center position of bolt 133 provided at rear coupling portion 106 of bracket 100.

As shown in fig. 9, the FI-ECU51, the ACG-ECU52, the generator 13, the battery 53, and other elements are electrically connected as described below by a circuit configuration including a first electric wire 61, a second electric wire 62, a third electric wire 63, and a fourth electric wire 64.

As shown in fig. 3, the main harness 65 is branched into a first harness 140 connected to the FI-ECU51 and a second harness 142 connected to the ACG-ECU 52. First harness 140 and second harness 142 branch off from main harness 65 below upper edge 20a of frame 20. The first harness 140 and the second harness 142 branch off from the main harness 65 below the upper end edge 25a1 of the first rail portion 25a of the seat rail 25.

The first harness 140 and the second harness 142 are branched from the main harness 65 below the center axis C1 of the first rail portion 25a. Here, the central axis C1 of the first rail portion 25a is a central axis of the first rail portion 25a (front-rear extending portion) extending in the front-rear direction. The center axis C1 of the first rail portion 25a extends linearly in the front-rear direction in a vehicle side view.

The first rail portion 25a is provided with a harness guide portion 150 that guides the main harness 65. The wire harness guide 150 is formed of a metal member, for example. The harness guide 150 includes: a curved portion 150a that is curved toward the left side so as to follow the outer periphery of the main harness 65 and guides the main harness 65 along the outer periphery of the first rail portion 25 a; and a coupling portion 150b extending rearward from a rear end (vehicle width direction inner end) of the curved portion 150a and coupled to the first rail portion 25a. For example, the joint portion 150b of the wire harness guide 150 is joined to the first rail portion 25a by welding. The first wire harness 140 and the second wire harness 142 are branched from the main wire harness 65 after passing through the harness guide 150.

The first harness 140 and the second harness 142 branch off from the main harness 65 at positions outside the first rail portion 25a in the vehicle width direction. The first harness 140 and the second harness 142 branch from the main harness 65 and then extend toward the coupler portions 113 and 143 of the ECUs 51 and 52 at positions on the vehicle width direction outer side of the first rail portion 25a.

The coupler 141 of the first harness 140 branched from the main harness 65 is connected to the coupler unit 113 of the FI-ECU 51. The first harness 140 branches from the main harness 65 in a vehicle side view, and is bent rearward and downward toward the coupler portion 113 of the FI-ECU51, and extends.

The coupler portion 113 of the FI-ECU51 has a connection port 113a of the FI-ECU51 and the first harness 140. The connection port 113a of the coupler portion 113 opens in the vehicle front-rear direction. For example, the FI-ECU51 can be connected to the first harness 140 by inserting the coupler 141 of the first harness 140 from the front into the connection port 113a of the coupler unit 113.

The first harness 140 is disposed between the upper end edge of the first rail portion 25a and the ACG-ECU 52. The first harness 140 is disposed between the center axis C1 of the first rail portion 25a and the upper end of the ACG-ECU main body 120 in a vehicle side view.

As shown in fig. 6, the front upper mounting portion 86 of the air cleaner 40 includes an extension portion 86a that extends outward in the vehicle width direction toward the rear upper extension portion 102 of the bracket 100 (the portion fixed to the bracket 100). The protruding portion 86a extends leftward from the upper front portion of the left side surface 80a of the air cleaner body 80 than the upper end of the rear upper protruding portion 102 of the bracket 100. The protruding portion 86a supports the first harness 140 from below. A part of the lower outer periphery of the first harness 140 is in contact with the upper surface of the extension portion 86a.

As shown in fig. 3, a coupler 143 of a second harness 142 branched from the main harness 65 is connected to the lower coupler part 124 of the ACG-ECU 52. For example, the second wire 142 includes at least one of the electric wires 61 to 64 described above. The second harness 142 branches from the main harness 65 in a vehicle side view, passes through the vicinity of the front of the ACG-ECU main body 120, bends downward and extends, and then bends rearward and upward toward the lower coupler portion 124 of the ACG-ECU 52.

In fig. 3, reference numeral 148 denotes a harness including at least the electric wire 62 described above (corresponding to a harness connecting the ACG-ECU52 and the generator 13), and reference numeral 149 denotes a coupler of the harness 148 connected to the lower coupler portion 124 of the ACG-ECU52 (corresponding to a coupler adjacent to the coupler 143 of the second harness 142). The wire harness 148 passes through the vicinity below the ACG-ECU main body 120 from the generator 13 (see fig. 1) and is bent rearward and extended inward in the vehicle width direction of the second wire harness 142 in a vehicle side view, and then is bent upward and extended toward the lower coupler portion 124 of the ACG-ECU52 (specifically, a portion of the lower coupler portion 124 on the rear side of a portion connected to the coupler 143 of the second wire harness 142). For example, the middle portion of the wire harness 148 may be fixed to a vehicle body or the like by a fixing member not shown. For example, the middle portion of the wire harness 148 may be fixed to the middle portion of the second wire harness 142 (for example, a portion of the second wire harness 142 that overlaps the wire harness 148 in a side view) by a fixing member (not shown).

A coupler 145 of a harness 144 extending from a midway portion of the second harness 142 is connected to the upper coupler portion 123 of the ACG-ECU 52. The harness 144 is bent and extends rearward and downward from a midway portion of the second harness 142 toward the upper coupler portion 123 of the ACG-ECU52 in a vehicle side view.

The second harness 142 connected to the lower coupler portion 124 of the ACG-ECU52 overlaps the front fixing point P1 in the vehicle side view. The second harness 142 is fixed to both outer sides of one direction side and the other direction side of the ACG-ECU52 with respect to a portion 142a (hereinafter also referred to as "overlap portion 142 a") overlapping the front fixing point P1 in a vehicle side view. In the present embodiment, the second wire 142 is fixed at positions above and below the overlapping portion 142 a.

As shown in fig. 5, the second wire harness 142 is fixed to the bracket 100 by an upper fixing member 151 provided at a position above the overlapping portion 142a and a lower fixing member 152 provided at a position below the overlapping portion 142 a. In fig. 5, reference numeral 146 denotes another wire harness, and reference numeral 153 denotes another fixing member for fixing the other wire harness 146 to the bracket 100.

The upper fixing member 151 includes: a restraining portion 151a that is annular along the outer periphery of the portion of the second wire 142 on the upper side of the overlapping portion 142a and that restrains the second wire 142; and an engaging portion 151b provided on the outer periphery of the restraining portion 151a and engaged with the front upper protruding portion 107 of the holder 100. As shown in fig. 3, restraint portion 151a of upper fixing member 151 is disposed in the vicinity of the front upper portion of the front end of ACG-ECU main body 120 in a vehicle side view. As shown in fig. 5, the engaging portion 151b of the upper fixing member 151 is disposed inward in the vehicle width direction from the front end side of the front upper extension portion 107 of the bracket 100.

As shown in fig. 3, the lower fixing member 152 includes: a restraining portion 152a that is annular along the outer periphery of a portion of the second wire 142 on the lower side than the overlapping portion 142a and that restrains the second wire 142; and an engaging portion 152b provided on the outer periphery of the restraining portion 152a and engaged with the front lower protruding portion 108 of the holder 100. Restraint portion 152a of lower fixing member 152 is disposed in the vicinity of the front of the lower end of ACG-ECU main body 120 in a vehicle side view. The engaging portion 152b of the lower fixing member 152 is disposed on the lower end side of the ACG-ECU main body 120 with respect to the front lower extension 108 of the bracket 100.

As shown in fig. 5, the front upper extension portion 107 of the bracket 100 is formed in a plate shape extending leftward from the upper front portion of the bracket main body 101 and then extending forward toward the inside in the vehicle width direction of the second harness 142. An engagement hole into which an engagement portion of the upper fixing member 151 can be engaged is provided on the front end side of the front upper extension portion 107 of the holder 100. For example, in a state where the portion of the second harness 142 above the overlapping portion 142a is restrained by the restraining portion 151a of the upper fixing member 151, the engaging portion 151b of the upper fixing member 151 is engaged with the engaging hole of the front upper protruding portion 107 from the left side. Thus, the portion of the second harness 142 above the overlapping portion 142a can be fixed to the front upper extension 107 of the bracket 100 via the upper fixing member 151.

As shown in fig. 3, the front downward extension 108 of the stand 100 is formed in a plate shape extending leftward from the lower front portion of the stand main body 101 and then rearward and downward toward the left side of the drain pipe 89. An engaging hole into which the engaging portion 152b of the lower fixing member 152 can be engaged is provided in a front portion of the front lower extension 108 of the bracket 100. For example, in a state where the portion of the second harness 142 below the overlapping portion 142a is restrained by the restraining portion 152a of the lower fixing member 152, the engaging portion 152b of the lower fixing member 152 is engaged with the engaging hole in the front portion of the front lower extension 108 from the front lower side. Thus, the portion of the second harness 142 below the overlapping portion 142a can be fixed to the front lower extension 108 of the bracket 100 via the lower fixing member 152.

As shown in fig. 5, the second harness 142 is arranged on the left side of the front fixing point P1. The overlapping portion 142a of the second wire harness 142 is separated leftward from the nut 132. A portion of the second harness 142 between the restraint portion 151a of the upper fixing member 151 and the restraint portion 152a of the lower fixing member 152 is bent toward the left side as viewed in the front of the vehicle. The second harness 142 extends obliquely so as to be positioned on the inside in the vehicle width direction as it goes upward from the restraining portion 151a of the upper fixing member 151 when viewed from the front of the vehicle.

For example, the second wire harness 142 is fixed by the upper fixing member 151 and the lower fixing member 152 so as to be kept separated from surrounding components including the nut 132 even when vibration occurs due to external factors such as vehicle vibration. As shown in fig. 3, for example, the second harness 142 is fixed by an upper fixing member 151 and a lower fixing member 152 so as to maintain a state of being separated from the ACG-ECU main body 120 even when vibration occurs due to an external factor such as vehicle vibration.

In the present embodiment, harness fixing points (fixing points) fixed on both outer sides of one direction side and the other direction side connected to the second harness 142 are provided to the bracket 100. Here, the wire harness fixing point refers to a central position of a portion where the fixing members 151 and 152 are fixed to the bracket 100. In the present embodiment, the harness fixing point corresponds to the center position of the portion where the engaging portions 151b, 152b of the fixing members 151, 152 are engaged with the bracket 100.

As shown in fig. 5, a harness fixing point PA (hereinafter also referred to as an "upper harness fixing point PA") in the engaging portion 151b of the upper fixing member 151 is disposed on the vehicle width direction inner side of a portion of the second harness 142 restrained by the restraining portion 151a in the vehicle front view. As shown in fig. 3, the second harness 142 overlaps the upper harness fixing point PA in a vehicle side view.

On the other hand, a harness fixing point PB (hereinafter also referred to as a "lower harness fixing point PB") of the engaging portion 152b of the lower fixing member 152 is disposed at a position not overlapping with the second harness 142 in a vehicle side view. As shown in fig. 5, the second wire harness 142 overlaps the lower-side harness fixing point PB as viewed from the front of the vehicle.

As shown in fig. 7, when the bracket 100 is viewed from the side of the vehicle, the upper harness fixing point PA corresponds to the center position of the engagement hole of the front upper protruding portion 107 of the bracket 100. As shown in fig. 5, when the bracket 100 is viewed from the front of the vehicle, the lower harness fixing point PB corresponds to the center position of the engagement hole in the front portion of the front lower extension portion 108 of the bracket 100.

< Effect >

As described above, the motorcycle 1 of the above embodiment includes the frame 20, the engine 11, the air cleaner 40 connected to the frame 20 and purifying the outside air supplied to the engine 11, the ACG-ECU52 provided on the left side surface 80a of the air cleaner 40 and fixed to the front fixing point P1 and the rear fixing point P2, and the second harness 142 (hereinafter also referred to as "harness 142") connected to the ACG-ECU52, and the harness 142 overlaps the front fixing point P1 in the vehicle side view.

For example, if the wire harness 142 does not overlap the front fixing point P1 in a vehicle side view, when the wire harness 142 vibrates due to external factors such as vehicle vibration, the wire harness 142 is likely to contact peripheral members located on the vehicle width direction inner side of the front fixing point P1. In this case, in order to avoid the wire harness 142 from abutting against the peripheral components, a fixing member for fixing the wire harness 142 needs to be newly provided. In contrast, according to the present configuration, since the wire harness 142 overlaps the front fixing point P1 in a vehicle side view, even if the wire harness 142 vibrates due to external factors such as vehicle vibration, the movement of the wire harness 142 to the inside in the vehicle width direction is restricted by the front fixing point P1, and therefore, it is possible to avoid a situation in which the wire harness 142 abuts against a peripheral member located on the inside in the vehicle width direction from the front fixing point P1. Further, a fixing member for fixing the wire harness 142 does not need to be newly provided. Therefore, the wire harness 142 can be prevented from abutting against peripheral components without increasing the number of components. Further, the wire harness 142 can be arranged compactly, compared to a case where the wire harness 142 does not overlap with the front fixing point P1 in a vehicle side view.

In the above embodiment, the wire harness 142 is fixed to both the outer sides of the one direction side and the other direction side connected to the ACG-ECU52 with reference to the portion 142a that overlaps with the front fixing point P1 in the vehicle side view.

With this configuration, the occurrence of vibration of the wire harness 142 due to an external factor can be suppressed. This can avoid the wire harness 142 from coming into contact with peripheral members around the front fixing point P1. Therefore, it is possible to suppress vibration of the wire harness 142 and avoid the wire harness 142 from coming into contact with peripheral members.

Further, the vibration of the wire harness 142 can be suppressed more effectively than in the case where the wire harness 142 is fixed only on the one side connected to the ACG-ECU52 with reference to the portion 142a overlapping the front fixing point P1 in the vehicle side view. Further, when the fixing portions of the harness 142 on both outer sides with respect to the portion 142a overlapping the front fixing point P1 in the vehicle side view are allocated near the ACG-ECU52, the harness 142 can be compactly arranged by effectively utilizing the space near the ACG-ECU 52.

In the above embodiment, the wire harness 142 is disposed at the vehicle width direction outer side of the front side fixing point P1, thereby providing the following effects.

Since the harness 142 can be installed after the ACG-ECU52 is fixed to the vehicle, the ease of assembly can be improved with a simple configuration. In addition, in the case where the cover member 39 such as a side cover is provided, when the wire harness 142 is arranged at the vehicle width direction outer side than the front fixing point P1, the wire harness 142 is easily covered by the cover member 39. Therefore, compactness and appearance can be improved without enlarging the cover member 39.

In the above embodiment, a part of the ACG-ECU52 is fixed via the bracket 100 at a position not overlapping with the air cleaner 40 in a vehicle side view, and the front fixing point P1 is arranged at a position not overlapping with the air cleaner 40 in a vehicle side view, thereby achieving the following effects.

Since a part of the ACG-ECU52 and the front-side fixing point P1 are disposed at positions that do not overlap with the air cleaner 40 in the vehicle side view, the heat of the ACG-ECU52 can be easily dissipated by the bracket 100, compared to a case where the ACG-ECU52 and the front-side fixing point P1 are all disposed at positions that overlap with the air cleaner 40 in the vehicle side view. When the front fixing point P1 is disposed near the air cleaner 40 in a side view of the vehicle, the wire harness 142 can be disposed by effectively utilizing the space near the air cleaner 40.

In the above embodiment, the bracket 100 is provided with the harness fixing points PA and PB, the front fixing point P1, and the rear fixing point P2, which are fixed to both outer sides of one direction side and the other direction side connected to the harness 142.

According to this configuration, by providing the harness fixing points PA and PB, the front fixing point P1, and the rear fixing point P2 to the same bracket 100, it is possible to assemble the harness 142 without providing a member for guiding the side thereof, while ensuring the positional relationship between the harness fixing points PA and PB, the front fixing point P1, and the rear fixing point P2 when assembling the harness to the vehicle body. Therefore, the assembling property can be improved without increasing the number of the components.

In the above embodiment, the generator 13 that generates electric power by driving the engine 11 is provided, and the generator 13 is disposed on the left side of the vehicle in the same manner as the ACG-ECU52, thereby achieving the following effects.

When the ACG-ECU52 is connected to the generator via the harness 142, the length of the harness 142 can be shortened, as compared to the case where the generator 13 is disposed on the opposite side of the ACG-ECU52 in the vehicle width direction. Therefore, vibration of the wire harness 142 can be suppressed, and the wire harness 142 can be prevented from coming into contact with peripheral members, and the wire harness 142 can be arranged compactly.

< second embodiment >

In the first embodiment, the FI-ECU51 is fixed to the left side surface 80a of the air cleaner 40 (see fig. 3), but the present invention is not limited thereto. As shown in fig. 10, the second embodiment is different from the first embodiment described above in that the FI-ECU is not fixed to the left side surface 80a of the air cleaner. In the following description, the same reference numerals are given to the same components as those in the first embodiment, and the description thereof is omitted.

The air cleaner 40 includes an air cleaner body 280 that bulges out to the left of the ACG-ECU 52. The air cleaner main body 280 includes a bulging portion 281 bulging leftward from the left side surface 80a of the air cleaner 40. The bulging portion 281 is disposed at the rear upper side of the ACG-ECU52 (a portion corresponding to the FI-ECU51 of the first embodiment) in the vehicle side view.

As shown in fig. 11, the left end of the bulging portion 281 is disposed on the left side of the ACG-ECU52 in the vehicle front view. The upper end of the bulging portion 281 is disposed above the front upper mounting portion 86 of the air cleaner 40 in a vehicle front view. The lower end of the bulging portion 281 is disposed below the upper coupler portion 123 of the ACG-ECU52 in the vehicle front view. The ACG-ECU52 overlaps with a part of the bulging portion 281 of the air cleaner 40 as viewed from the front of the vehicle.

As described above, according to the motorcycle of the present embodiment, the ACG-ECU52 is provided on the left side surface 80a of the air cleaner 40 and overlaps with a part of the air cleaner 40 in the vehicle front view, thereby achieving the following effects.

For example, if the ACG-ECU52 is provided on the left side surface 80a of the air cleaner 40 and is disposed at a position that does not overlap with the air cleaner 40 when viewed from the front of the vehicle, the capacity of the air cleaner 40 may be limited by the presence of the ACG-ECU 52. In contrast, according to the present configuration, the ACG-ECU52 overlaps a portion of the air cleaner 40 (a portion of the bulging portion 281) as viewed from the front of the vehicle, whereby the portion overlapping the ACG-ECU52 as viewed from the front of the vehicle can secure the capacity of the air cleaner 40. Therefore, the ACG-ECU52 can be disposed on the left side surface 80a of the air cleaner 40, and the capacity of the air cleaner 40 can be ensured.

< modification example >

In the above embodiment, the FI-ECU51 is provided on the left side surface 80a of the air cleaner 40, but the present invention is not limited thereto. For example, the FI-ECU51 may be provided on the right side surface of the air cleaner 40. For example, the FI-ECU51 may be provided on one side surface of the air cleaner 40. For example, the installation mode of the FI-ECU51 can be changed according to the required specification.

In the above embodiment, the example in which the wire harness 142 overlaps the front fixing point P1 in the vehicle side view and is fixed to the upper side and the lower side of the portion 142a overlapping the front fixing point P1 in the vehicle side view has been described, but the present invention is not limited to this. For example, the wire harness 142 may overlap with another fixing point (a plurality of fixing points) other than the front fixing point P1 in a vehicle side view. For example, the wire harness 142 may be fixed to both outer sides of the portion overlapping with the plurality of fixing points in a vehicle side view. For example, in the case where the wire harness extends in the vehicle front-rear direction, the wire harness may be fixed on the front side and the lower side of the portion overlapping with the front fixing point P1 in a vehicle side view. For example, the fixing form of the wire harness can be changed according to the required specification.

In the above embodiment, the example in which the wire harness 142 is disposed on the vehicle width direction outer side of the front fixing point P1 has been described, but the present invention is not limited to this. For example, the wire harness 142 may be arranged further inward in the vehicle width direction than the front fixing point P1. For example, the arrangement of the wire harness 142 may be changed according to the required specification.

In the above embodiment, an example was described in which a part of the ACG-ECU52 is fixed via the bracket 100 at a position not overlapping with the air cleaner 40 in a vehicle side view, and the front fixing point P1 is arranged at a position not overlapping with the air cleaner 40 in a vehicle side view, but the present invention is not limited to this. For example, the ACG-ECU52 and the front-side fixing point P1 may be all disposed at positions overlapping the air cleaner 40 in a vehicle side view. For example, the arrangement of the ACG-ECU52 and the front fixing point P1 with respect to the air cleaner 40 may be changed in accordance with the required specifications.

In the above embodiment, the generator 13 that generates electric power by driving the engine 11 is provided and the generator 13 is disposed on the left side of the vehicle similar to the ACG-ECU 52. For example, the generator 13 may be disposed on the opposite side of the ACG-ECU52 in the vehicle width direction. For example, the arrangement of the generator 13 and the ACG-ECU52 may be changed according to the required specifications.

In the above embodiment, the example in which the harness fixing points PA and PB fixed to both outer sides of one direction side and the other direction side connected to the harness 142, the front fixing point P1, and the rear fixing point P2 are provided in the bracket 100 has been described, but the present invention is not limited to this. For example, at least one of the harness fixing points PA and PB and the front fixing point P1 may be provided in the bracket 100, and the rear fixing point P2 may not be provided in the bracket 100. For example, at least one of the harness fixing points PA, PB, the front fixing point P1, and the rear fixing point P2 may be provided to a member different from the bracket 100. For example, the installation form of each fixing point can be changed according to the required specification.

In the above embodiment, the FI-ECU51 for controlling the engine 11 and the ACG-ECU52 for controlling the generator 13 are separately provided, but the present invention is not limited thereto. For example, only a single control unit that controls the engine 11 and the generator 13 may be provided as the control unit. For example, the form of the control unit can be changed according to the required specification.

In the above embodiment, the example in which the wire harness 142 connected to the ACG-ECU52 is fixed to both outer sides of the portion 142a that overlaps with the front fixing point P1 in the vehicle side view has been described, but the present invention is not limited to this. For example, in the case where the harness 140 connected to the FI-ECU51 overlaps the fixed point in the vehicle side view, the harness 140 may be fixed on both outer sides of the portion overlapping the fixed point in the vehicle side view. For example, the fixing form of the wire harness connected to the control unit can be changed according to the required specification.

In the above embodiment, the ACG-ECU52 is described as an example of overlapping a part of the air cleaner 40 in a vehicle side view, but the present invention is not limited to this. For example, the control unit may be extended such that a part of the air cleaner does not overlap the drive device side, and the fixed point may be provided on the drive device side of the control unit. For example, if the control unit is extended, a protective member needs to be provided to avoid the wire harness from coming into contact with the driving device and a member located on the vehicle width direction inner side of the fixed point. In contrast, according to the embodiment, the wire harness overlaps (in other words, is arranged so as to pass over) the fixing point of the control unit in the vehicle side view, and thus the contact can be avoided without increasing the number of components.

In the above embodiment, the description has been given taking an example in which the engine is a single cylinder engine, but the present invention is not limited to this. For example, the engine may be a multi-cylinder engine. For example, the form of the engine can be changed according to the required specifications.

In the above embodiment, the engine is described as an example of the driving device, but the present invention is not limited to this. For example, the drive device may be a device other than an engine (internal combustion engine) such as an electric motor. For example, the driving device may be a motor such as an electric motor, a heat engine, or a fluid machine, or may be a device in which at least two of the motors are combined. For example, the form of the driving device can be changed according to the required specification.

In the above-described embodiment, a motorcycle having an engine mounted on a vehicle body side is described as an example of a saddle-ride type vehicle, but the present invention is not limited to this. For example, the straddle-type vehicle may be a unit swing type motorcycle. For example, the form of the saddle-ride type vehicle can be changed according to the required specifications.

The present invention is not limited to the above embodiments, and can be applied to a saddle-ride type vehicle other than a motorcycle. For example, the saddle-ride type vehicle includes all vehicles in which a driver rides over a vehicle body, and includes not only motorcycles (including bicycles with a prime mover and scooter type vehicles) but also vehicles having three wheels (including front two-wheel and rear one-wheel vehicles in addition to front two-wheel and rear two-wheel vehicles). In addition, the present invention can be applied not only to a motorcycle but also to a four-wheeled vehicle such as a motor vehicle (four-wheeled truck, etc.).

The present invention is also applicable to vehicles other than straddle-type vehicles (passenger cars, buses, trucks, etc.). The present invention is applicable not only to vehicles but also to vehicles and moving bodies other than vehicles such as aircrafts, ships, construction machines, and industrial machines. For example, the present invention is applicable not only to vehicles but also to hand-pushed lawnmowers, sweepers, and the like. Furthermore, the present invention can be applied not only to a moving body but also to a fixed type device fixed at a fixed position. For example, the electrical component arrangement structure may include a frame, a driving device, an air cleaner connected to the frame and purifying outside air supplied to the driving device, a control unit provided on an outer surface of one side of the air cleaner and fixed at least one fixing point, and a wire harness connected to the control unit, and the wire harness may overlap the at least one fixing point in a side view.

The configuration of the above embodiment is an example of the present invention, and the components of the embodiment may be replaced with known components, and various changes may be made without departing from the scope of the present invention.
