In the above invention, one end portion and the other end portion of the belt 68 may be fixed to the battery housing portion 60, the cover portion 88 may be provided at the one end portion of the belt 68, and the other end portion of the belt 68 may be covered with the negative-side harness 80n.

In the above invention, the other end of the belt 68 may include: a side wall portion 89 provided upright from the belt main body portion 85 extending along the one side surface 51a of the battery 51; and an engaging portion 90 that protrudes from the side wall portion 89, engages with the battery housing portion 60, and the side wall portion 89 overlaps with the negative-side harness 80n when viewed in an insertion direction in which the engaging portion 90 is inserted into the battery housing portion 60.

In the above invention, the battery housing portion 60 may include a wall portion 81 to which the engagement portion 90 of the belt 68 is engaged, and the side wall portion 89 may be located between the negative-side harness 80n and the wall portion 81.

Further, the above invention may be configured such that: the belt 68 is inserted into the wall portion 81 by sliding, the positive side harness 80p connected to the positive terminal 51p is routed along the sliding direction of the belt 68, and the covering portion 88 is formed in a dome shape having an opening portion 88a in the sliding direction.

Further, the above invention may be configured such that: the battery 51 is housed such that the one side surface 51a is located deeper than the opening 61e of the battery housing portion 60, and the battery housing portion 60 includes a notch portion 61g that exposes the peripheral wall 51b of the battery 51.

Effects of the invention

According to the present invention, a battery arrangement structure for a vehicle includes: a battery having a positive terminal and a negative terminal on one side; a battery housing portion that houses a battery; and a belt that fixes the battery to the battery housing, the belt being provided so as to cross an opening of the battery housing, the opening exposing one side surface of the battery to the outside, the belt including a covering portion that covers the positive terminal, and a negative-side harness covering belt connected to the negative terminal. According to this structure, since the covering portion of the belt covers the positive terminal, it is difficult to detach the positive terminal side if the belt is not detached. Further, since the tape is covered with the negative side wire harness, it is difficult to detach the tape if the negative side wire harness is not detached. Therefore, it is suggested to detach the negative side wire harness prior to the positive terminal side.

In the above invention, one end portion and the other end portion of the belt may be fixed to the battery housing portion, the belt may include a covering portion at the one end portion, and the other end portion of the belt may be covered with the negative-side harness. According to this configuration, the cover portion is provided at one end portion of the belt fixed to the battery housing portion, and therefore, the positive terminal can be firmly covered with the cover portion. Further, since the other end portion of the belt fixed to the battery housing portion is covered with the negative-side harness, the other end portion of the belt can be effectively prevented from being detached by the negative-side harness.

In the above invention, the other end portion of the belt may include: a side wall portion that is provided upright from a band main body portion that extends along one side surface of the battery; and an engaging portion that protrudes from the side wall portion and engages with the battery housing portion, the side wall portion overlapping with the negative-side wire harness when viewed in an insertion direction in which the engaging portion is inserted into the battery housing portion. According to this configuration, when the engagement portion is to be released from insertion into the battery housing portion, the negative-side harness becomes an obstacle to movement of the side wall portion. Therefore, the belt can be prevented from being detached before the negative-side wire harness is detached.

In the above invention, the battery housing portion may include a wall portion to which the engagement portion of the belt is engaged, and the side wall portion may be located between the negative-side harness and the wall portion. According to this configuration, the movement of the belt can be firmly restricted by the wall portion and the negative-side harness.

In the above invention, the belt may be inserted into the wall portion by sliding, the positive harness connected to the positive terminal may be routed along the sliding direction of the belt, and the covering portion may be formed in a dome shape having an opening portion in the sliding direction. According to this configuration, the front-side harness can be covered over a wide range by the dome-shaped covering portion while the belt is made slidable. Further, since the positive-side harness is routed along the sliding direction of the belt, the positive-side harness is less likely to be an obstacle to movement of the side wall portion of the belt when the belt slides, and the belt can be smoothly slid.

In the above invention, the battery may be housed such that one side surface of the battery is located deeper than the opening of the battery housing portion, and the battery housing portion may include a notch portion that exposes the peripheral wall portion of the battery. According to this configuration, the peripheral wall portion of the battery can be accessed via the cutout portion, and the battery can be easily taken out from the battery housing portion.

The cover 70 includes receiving portions 77, and when the cover 70 is in an open state, the receiving portions 77, 77 abut against the upper surfaces of the case fixing portions 62a, 63a.

The stoppers 16e, 16e are provided: in the state where the cover 70 is opened, the receiving portions 77, 77 are approached from the rear. The stoppers 16e and 16e restrict the movement of the receiving portions 77 and 77 to the rear. Therefore, as shown in fig. 5 and 8, even if the cover swing support portions 65, 65 have the open portions 65c, the swing shafts 71, 71 of the cover 70 can be prevented from coming out of the open portions 65c, 65c in the rearward direction.

When the cover 70 is attached to and detached from the battery case 60, the battery case 60 is detached from the vehicle body frame 10. In this state, since the stoppers 16e and 16e do not interfere with each other, the swing shafts 71 and 71 can be attached to and detached from the cover swing support portions 65 and 65 through the opening portions 65c and 65c.

Next, the peripheral structure of the belt 68 for fixing the battery 51 will be explained.

Fig. 11 is a plan view of the battery 51 housed in the battery case 60 as viewed from above. In fig. 11, the cover 70 is not shown.

Referring to fig. 5, 6, and 11, the battery 51 is housed in the battery case 60 such that one side surface, i.e., the upper surface 51a, is exposed upward from the opening 61e of the battery case 60. The upper surface 51a of the battery 51 is rectangular, and the battery 51 is disposed in an orientation in which the longitudinal direction of the upper surface 51a substantially coincides with the vehicle width direction.

The battery 51 is housed in the battery case 60 such that the upper surface 51a is located deeper than the upper end of the opening 61e of the battery case 60.

Battery 51 includes a positive terminal 51p at one end in the vehicle width direction of the front end of upper surface 51a, and a negative terminal 51n at the other end in the vehicle width direction of the front end of upper surface 51 a.

That is, the plus terminal 51p and the minus terminal 51n are arranged at the front end of the upper surface 51a so as to be linearly aligned in the longitudinal direction (vehicle width direction) of the upper surface 51 a. The arrangement direction of the positive terminal 51p and the negative terminal 51n is the vehicle width direction.

The positive terminal 51p is connected to a positive side harness 80p, and the negative terminal 51n is connected to a negative side harness 80n.

The positive wire harness 80p is drawn out from the positive terminal 51p toward the negative terminal 51n along the longitudinal direction of the upper surface 51a, bent forward in front of the negative terminal 51n, and extends outward of the case body 61.

The negative harness 80n is drawn rearward from the negative terminal 51n in the lateral direction of the upper surface 51 a.

That is, the wiring directions of the positive side wire harness 80p and the negative side wire harness 80n on the upper surface 51a of the battery 51 are substantially perpendicular.

Fig. 12 is a plan view of the peripheral portion of the battery 51 with the positive-side wire harness 80p, the negative-side wire harness 80n, and a belt fixing member 84 described later removed.

Referring to fig. 5, 6, 11, and 12, battery case 60 includes a wall portion 81 extending upward from upper surface 51a of battery 51 in the vicinity of negative terminal 51n. The wall portion 81 extends upward along the right side wall 61b of the case body 61. An engagement hole 81a penetrating the wall portion 81 in the vehicle width direction is formed in an upper portion of the wall portion 81.

The battery case 60 includes a step portion 82 on the upper surface of the side extension portion 62. The mesa 82 is continuous with the upper end of the left side wall 61a of the case body 61.

The battery case 60 is provided with a tape fixing portion 83 provided on the upper surface of the table portion 82 at a position closer to the side wall 61 a. A tape fixing hole portion 83a is provided on the upper surface of the tape fixing portion 83. The tape fixing hole 83a is, for example, a clamp nut attached to the tape fixing portion 83.

The tape fixing portion 83 includes a projection 83b projecting outward so as to extend along the upper surface of the mesa portion 82.

The belt 68 is a belt-shaped plate member that is long in the vehicle width direction. The belt 68 is provided across the opening 61e of the case main body portion 61 in the vehicle width direction, and the belt 68 covers a part of the upper surface 51a of the battery 51 from above, thereby fixing the battery 51 to the battery case 60.

The belt 68 extends in the longitudinal direction of the upper surface 51a of the battery 51 behind the positive terminal 51p and the negative terminal 51n. That is, the belt 68 extends in the vehicle width direction along the arrangement direction of the positive terminal 51p and the negative terminal 51n.

One end portion of the belt 68 in the longitudinal direction is fixed to the belt fixing portion 83 by a belt fixing member 84, and the other end portion in the longitudinal direction is fixed to the wall portion 81. The belt fastener 84 is, for example, a bolt.

The belt 68 includes a belt body 85 linearly extending along the upper surface 51a of the battery 51.

In detail, at one end of the belt 68, there are provided: a hole 86 through which the tape fixing member 84 is inserted; a side surface engaging portion 87 that engages with the projection 83b of the tape fixing portion 83; and a covering portion 88 that covers the positive terminal 51p and the positive-side wire harness 80p from above.

The side surface engagement portion 87 is a hole formed in an end surface of the belt 68 in the vehicle width direction.

The side surface engaging portion 87 is engaged with the protrusion 83b, and the band fixing member 84 inserted through the hole 86 is fastened to the band fixing hole portion 83a, whereby one end portion of the band 68 is fixed to the battery case 60.

The covering portion 88 extends from the belt main body portion 85 toward the front positive terminal 51p.

The covering portion 88 is formed in a dome shape covering the plus terminal 51p from above, front, rear, and the outside in the vehicle width direction, and includes an opening portion 88a that opens to the inside in the vehicle width direction.

At the other end of the belt 68 are provided: a side wall portion 89 extending upward from the belt main body portion 85 so as to be along the wall portion 81 of the battery case 60; and an engaging portion 90 extending outward in the vehicle width direction from an upper end of the side wall portion 89.

The other end portion of the belt 68 is fixed to the battery case 60 by inserting and engaging the engagement portion 90 into the engagement hole 81a of the wall portion 81 of the battery case 60 from the inside in the vehicle width direction.

That is, the belt 68 slides in the vehicle width direction along the upper surface 51a of the battery 51, whereby the engagement portion 90 engages with the engagement hole 81a, and the side surface engagement portion 87 engages with the protrusion 83b. After that, the strap 68 is fixed to the battery case 60 by tightening the strap mount 84. The opening portion 88a of the covering portion 88 is opened in the sliding direction of the belt 68.

Referring to fig. 6 and 11, the negative-side harness 80n covers the belt main body 85 from above at the other end portion of the belt 68. That is, the other end portion of the belt 68 is sandwiched between the negative-side harness 80n and the upper surface 51a of the battery 51.

Further, the side wall portion 89 of the other end portion of the belt 68 is sandwiched between the negative-side wire harness 80n and the wall portion 81 of the battery case 60.

When viewed in the insertion direction of the belt 68 with respect to the insertion of the wall portion 81 (the sliding direction of the belt 68), the side wall portion 89 of the belt 68 overlaps the side surface of the negative-side wire harness 80n.

The connection end 80p1 of the positive side wire harness 80p connected to the positive terminal 51p and the positive terminal 51p are covered with the cover 88.

Here, an example of the procedure of taking out the battery 51 from the battery case 60 will be described.

In the state of fig. 11, the positive side harness 80p is covered by the covering portion 88 of the belt 68 fixed to the battery case 60, and therefore the covering portion 88 becomes an obstacle, and it is difficult to detach the positive side harness 80p from the positive terminal 51p.

In the state of fig. 11, the other end portion of the belt 68 is covered with the negative side wire harness 80n, and therefore, the negative side wire harness 80n hinders the detachment of the belt 68, making it difficult to detach the belt 68.

In the state of fig. 11, even if the tape fixing member 84 is removed, the negative-side wire harness 80n is positioned in the sliding direction of the tape 68 when the tape 68 is removed from the wall portion 81, and therefore the negative-side wire harness 80n becomes an obstacle to the sliding movement of the side wall portion 89, and it is difficult to remove the tape 68. Further, the presence of the wall 81 makes it difficult to remove the belt 68 by sliding it toward the wall 81.

Thus, it is suggested that the worker should detach the negative side wire harness 80n before detaching the positive side wire harness 80p and the belt 68.

As shown in fig. 12, in a state where the negative side wire harness 80n and the belt anchor 84 are removed, the worker can remove the belt 68 by sliding the belt 68 in the vehicle width direction toward the positive terminal 51p side. Thereby, the connection end portion 80p1 of the positive wire harness 80p is exposed, and the worker can detach the positive wire harness 80p from the positive terminal 51p.

In the present embodiment, when the battery 51 is attached to the battery case 60, it can be suggested that the positive side harness 80p should be attached before the negative side harness 80n.

That is, if the negative-side harness 80n and the strap 68 are attached before the positive-side harness 80p, the covering portion 88 becomes an obstacle, and it is difficult to connect the positive-side harness 80p to the positive terminal 51p.

The upper portion of the peripheral wall 51b of the battery 51 is exposed outward from the notches 61g and 61g formed in the rear wall 61c and the front wall 61d of the case body 61. Therefore, when the operator attaches and detaches the battery 51, the operator can grip the battery 51 through the notches 61g and 61g, and the workability is good.

Next, the structure of the fuel tank cover 41 will be explained.

Fig. 13 is a plan view of the peripheral portion of the fuel tank cover 41. Fig. 14 is a front view of the peripheral portion of the fuel tank cover 41 as viewed from the front. The steering system 12 and the like are not shown in fig. 13 and 14.

Referring to fig. 1, 13, and 14, the fuel tank cover 41 includes: a fuel tank center cover 92 that covers a center portion of the fuel tank 35 in the vehicle width direction from above; and a pair of left and right tank side covers 93, 93 that cover left and right side surfaces of the fuel tank 35.

The motorcycle 1 further includes: an inner cover 94 that covers the fuel tank 35 forward; and a pair of left and right pipe covers 95, 95 provided between the shrouds 42, 42 and the inner cover 94.

The fuel tank center cover 92 extends linearly from the vicinity of the rear of the front seat pipe 15 to the front edge of the front seat 14 a. The filler opening 35a is exposed upward from an opening provided in the fuel tank center cover 92.

The tank side covers 93, 93 extend from the side edges of the tank center cover 92 outward and downward in the vehicle width direction along the upper surface and the side surfaces of the fuel tank 35.

Bulging portions 93a, 93a bulging outward in the vehicle width direction are provided at front portions of the fuel tank side covers 93, and the shrouds 42, 42 are attached to outer surfaces of front end portions of the bulging portions 93a, 93 a.

Gaps 96 and 96 through which traveling wind passes are formed between the rear edges of the shrouds 42 and the bulging portions 93a and 93 a. The gaps 96, 96 are formed from the upper surfaces of the bulging portions 93a, 93a to the side surfaces of the bulging portions 93a, 93 a.

The inner cover 94 integrally includes: a pair of left and right cover portions 94a, 94a provided between the fuel tank side covers 93, 93 and the main frames 16, 16; and a coupling portion 94b that couples the cover portions 94a, 94a to the left and right. The connection portion 94b extends in the vehicle width direction rearward of the front seat pipe 15 and above the main frames 16, 16. The connection portion 94b passes below the front edge of the fuel tank cover 41.

The cover portions 94a, 94a of the inner cover 94 include inner side surface portions 94c, 94c that face the inner surfaces of the covers 42, 42 from the inside in the vehicle width direction.

The duct covers 95, 95 cover air guide ports 97, 97 formed between the front edges of the shrouds 42, 42 and the front edges of the inner side surface portions 94c, 94c of the inner shroud 94. The duct covers 95, 95 are formed in a net shape so as to allow traveling wind to pass.

The traveling wind sucked into the space between the shroud 42 and the inner side surfaces 94c, 94c through the wind guide ports 97, 97 is discharged to the outside through the gaps 96, 96.

Specifically, the traveling wind is discharged to the outside from both the gaps 96 and 96 on the upper surface side of the bulging portions 93a and the gaps 96 and 96 on the side surface side of the bulging portions 93a and 93 a.

As shown in fig. 1, the front edges of the shrouds 42, 42 are located rearward of the front forks 25, 25 when the vehicle is viewed in side view, and are inclined rearward along the rear edges of the front forks 25, 25. The rear edges of the front forks 25, 25 are substantially parallel to the front edges of the shrouds 42, 42. This allows the traveling wind flowing from the front to the shroud 42, 42 side through the periphery of the front fork 25, 25 to be smoothly guided to the wind guide opening 97, 97.

As described above, according to the embodiment to which the present invention is applied, the battery arrangement structure of the motorcycle 1 includes: a vehicle frame 10 including main frames 16, 16 extending from a front pillar 15 to the rear of a vehicle body; a fuel tank 35 located above the main frames 16, 16; an engine 11 located below the main frames 16, 16; and a battery 51, and the fuel tank 35 is swingably supported by the frame 10 via a fuel tank swing support portion 50 provided at a rear end portion thereof. The battery 51 is provided between the fuel tank 35 and the engine 11, and is disposed on the side opposite to the side where the fuel tank swing support portion 50 is provided, that is, on the front end portion side of the fuel tank 35. Thus, when the fuel tank 35 is swung by the fuel tank swing support portion 50, the battery 51 positioned below the fuel tank 35 is exposed upward. The battery 51 is disposed on the side opposite to the side on which the fuel tank swing support portion 50 is provided, and is located on the side on which the amount of movement of the fuel tank 35 due to the swing is large, and therefore the battery 51 is largely exposed to the outside. Therefore, the battery 51 disposed below the fuel tank 35 can be easily accessed.

The battery 51 is disposed at a position at which at least a part thereof overlaps the main frames 16, 16 when the vehicle is viewed in a side view. This can suppress the height of the battery 51 from above and below.

A pair of left and right main frames 16, 16 are provided, and a battery 51 is disposed between the left and right main frames 16, 16. This enables the battery 51 to be disposed in the space between the left and right main frames 16, 16. Even in a configuration in which the battery 51 is difficult to access from the side due to the presence of the left and right main frames 16, the battery 51 can be accessed from above.

The battery case 60 is provided to house the battery 51, and the lid 70 is provided to the battery case 60 and covers the battery 51 from above. This can protect the battery 51 from above with the lid 70.

The lid 70 is swingably supported by the battery case 60 via the lid swing support portions 65, and the lid 70 includes fuel tank contact portions 75, and when the lid 70 is swung to an open state in which the batteries 51 are exposed, the fuel tank contact portions 75, 75 come into contact with the fuel tank 35. This allows the fuel tank 35 to be supported in a swung state by the lid 70 that is opened when the battery 51 is approached, and the battery 51 can be easily approached.

The cover 70 includes fuel tank contact portions 75, 75 at an end portion on the opposite side to the side where the cover swing support portions 65, 65 are provided. This enables the fuel tank 35 to be supported by the lid 70 at a greatly swung position, thereby facilitating access to the battery 51.

The cover swing support portions 65 and 65 are provided at the end portions of the cover 70 on the side closer to the tank swing support portion 50, among the end portions in the front-rear direction. Thus, the battery 51 is exposed on the opposite side to the fuel tank swing support portion 50 side in a state where the fuel tank 35 is supported by the cover 70 opened by the cover swing support portions 65, 65. Therefore, the lid 70 and the fuel tank 35 are less likely to be obstacles, and the battery 51 is easily accessible.

The fuel tank contact portions 75, 75 are provided at positions overlapping the main frames 16, 16 from above in a plan view. This allows the main frames 16 and 16 to effectively receive the weight of the fuel tank 35 via the fuel tank contact portions 75 and 75.

In addition, according to an embodiment to which the present invention is applied, the battery arrangement structure of the motorcycle 1 includes: a battery 51 having a positive terminal 51p and a negative terminal 51n on an upper surface 51 a; a battery case 60 that houses the battery 51; and a belt 68 that fixes the battery 51 to the battery case 60, the belt 68 being provided so as to straddle the opening 61e of the battery case 60 that exposes the upper surface 51a of the battery 51 to the outside, the belt 68 including a covering portion 88 that covers the positive terminal 51p, and a negative harness 80n connected to the negative terminal 51n covering the belt 68.

According to this structure, since the covering portion 88 of the belt 68 covers the positive terminal 51p, it is difficult to detach the positive side wire harness 80p without detaching the belt 68. Further, the belt 68 is covered with the negative side wire harness 80n, so it is difficult to detach the belt 68 if the negative side wire harness 80n is not detached. Therefore, it can be suggested that the negative side harness 80n is detached prior to the positive side harness 80p.

One end and the other end of the belt 68 are fixed to the battery case 60, the belt includes a covering portion 88 at the one end, and the other end of the belt 68 is covered with the negative-side harness 80n. Thus, the belt 68 includes the covering portion 88 at one end portion of the belt 68 fixed to the battery case 60, and therefore the positive terminal 51p can be firmly covered with the covering portion 88. Further, since the other end portion of the strap 68 fixed to the battery case 60 is covered with the negative-side harness 80n, the other end portion of the strap 68 can be effectively prevented from being detached by the negative-side harness 80n.

Further, the other end portion of the belt 68 includes: a side wall portion 89 provided upright from the belt main body portion 85 extending along the upper surface 51a of the battery 51; and an engaging portion 90 that protrudes from the side wall portion 89 and engages with the battery case 60, and the side wall portion 89 overlaps with the negative-side harness 80n when viewed in an insertion direction in which the engaging portion 90 is inserted into the battery case 60. Thus, when the insertion of the engaging portion 90 into the battery case 60 is to be released, the movement of the side wall portion 89 is prevented by the negative-side harness 80n. Therefore, the tape 68 can be prevented from being detached before the negative-side wire harness 80n is detached.

The battery case 60 includes a wall portion 81 to which the engagement portion 90 of the belt 68 is engaged, and the side wall portion 89 is located between the negative-side harness 80n and the wall portion 81. This enables the movement of the strap 68 to be firmly restricted by the wall portion 81 and the negative-side harness 80n.

The belt 68 is inserted into the wall portion 81 by sliding, the positive-side harness 80p connected to the positive terminal 51p is routed along the sliding direction of the belt 68, and the covering portion 88 is formed in a dome shape having an opening portion 88a in the sliding direction. This enables the positive-side wire harness 80p to be covered over a wide range by the dome-shaped covering portion 88 while allowing the belt 68 to slide. Further, since the positive side wire harness 80p is routed along the sliding direction of the belt 68, the positive side wire harness 80p is less likely to interfere with the movement of the side wall portion 89 of the belt 68 when the belt 68 slides, and the belt 68 can slide smoothly.

The battery 51 is housed such that the upper surface 51a is located deeper than the opening 61e of the battery case 60, and the battery case 60 includes notches 61g and 61g that expose the peripheral wall 51b of the battery 51. This allows the peripheral wall 51b of the battery 51 to be accessed via the notches 61g and 61g, and the battery 51 can be easily removed from the battery case 60.

The above embodiment shows an embodiment to which the present invention is applied, and the present invention is not limited to the above embodiment.

In the above embodiment, the following configuration is explained: the fuel tank 35 is swingably supported by the frame 10 via a fuel tank swing support portion 50 provided at a rear end portion thereof, and the battery 51 is provided between the fuel tank 35 and the engine 11 and on a front end portion side of the fuel tank 35. For example, the fuel tank 35 may be swingably supported by the frame 10 following a fuel tank swing support portion provided at a front end portion thereof, and the battery 51 may be provided between the fuel tank 35 and a rear portion of the crankcase 30 of the engine 11 and below a rear end portion of the fuel tank 35.

In the above embodiment, the following configuration is explained: a pair of left and right main frames 16, 16 are provided, and a battery 51 is disposed between the left and right main frames 16, 16. However, the present invention is not limited thereto. For example, the battery may be disposed so as to overlap with a main frame that extends rearward from the front seat pipe 15 in a single manner when the vehicle is viewed in side view.

In the above embodiment, the box-shaped battery case 60 is described as an example of the battery housing, but the present invention is not limited to this. The battery housing portion may be formed in a shape capable of housing the battery 51, for example, by a plurality of vehicle body members.

In the above embodiment, the motorcycle 1 has been described as an example, but the present invention is not limited to this, and the present invention can be applied to a three-wheel saddle-ride type vehicle having two front wheels or two rear wheels, a saddle-ride type vehicle having wheels of four wheels or more, and a saddle-ride type vehicle such as a scooter.
