DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery arrangement for a motorcycle, and more particularly to a battery arrangement for a motorcycle in which a large-capacity battery is mounted compactly.

[0002]

2. Description of the Related Art In general, a battery of a motorcycle is accommodated below a driver's seat together with electrical components such as a fuse (for example, Japanese Utility Model Application Laid-Open No. Sho 62-97891).

[0003]

However, with the diversification of auxiliary equipment, the degree of freedom in arranging the equipment has been reduced, and with the increase in power consumption, a large capacity battery has been required. In order to optimize the equipment arrangement in the limited space, it is necessary to study a structure for mounting an electric system including a battery.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a rear end of a swing arm having an engine disposed at a substantially central portion of a vehicle body in a vehicle width direction and extending rearward from near the engine. A motorcycle that pivotally supports a rear wheel at a portion thereof and arranges a seat above the swing arm, wherein a chain that drives a rear wheel along a swing arm is arranged on one side of the vehicle body, and the other side of the vehicle body A battery storage box is provided below the seat at one side of the vehicle body on the side having the chain, above the rear wheel, and the battery storage box is provided with the chain. The battery storage box is disposed on the side having the vehicle body in the vehicle width direction when viewed from the rear side of the vehicle body such that a lower portion thereof is located outside in the vehicle width direction and an upper portion thereof is located on the center side in the vehicle width direction. Arranged to incline to the side, All bending <br/> time of the chain Cayce the serial chain, the surface inclined to the vehicle body center line of the battery storage box
Triangle with hypotenuse and two other sides composed of horizontal and vertical lines
So that part of the chain case is located in the area of the shape
The battery storage box is disposed, and the outer side of the battery storage box is covered with a side cover whose lower part is located outward in the vehicle width direction and which is inclined toward the center of the vehicle body as viewed upward from the rear of the vehicle body.

[0005]

[Function] Since a heavy object such as a battery and an exhaust pipe can be distributed to both sides of the vehicle body, the weight balance between the left and right of the motorcycle is improved, and since the battery is disposed above the vehicle body, a large stroke of the swing arm can be secured. Place the battery in the lower part on the outside in the vehicle width direction and on the upper part in the center in the vehicle width direction.
The side cover that covers the outside of the battery storage box is inclined toward the center in the vehicle width direction when viewed from the rear of the vehicle so as to be located on the side, and is inclined toward the center of the vehicle as viewed from the rear of the vehicle as it goes upward. Therefore, the occupant's legs can be placed inside without being spread.

The front and rear ends 5b and 5c of the battery storage box 5 are fixed to the holder pipe 2d with bolts. The front end side of the battery storage box 5 is an electrical component storage section 11 for storing the electrical component 10. The electrical component storage unit 11 includes a fuse 10a on the front side of the drawing in FIG.
Is arranged. The fuse 10a protects the current of the circuit, and the stagger switch 10b is a starter current control relay switch. The rear end side of the battery storage box 5 is a battery holding unit 13 that stores a sealed battery 12.

The battery 12 is held on bottom plates 13a of the battery holders 13 and end walls 13b, 13c in the longitudinal direction of the vehicle body via cushion rubbers 13d, 13e, 13f. It is pressed from the side by the fixing plate 13g with bolts.

The positive electrode 12a of the battery 12 is placed on the front side of the vehicle in the battery holder 13, and a connecting conductor 14a is mounted between the positive electrode 12a and the stagger switch 10b.
The lower side of the bottom plate 13a of the battery holding unit 13 is provided with an electrode cord 14b of the battery 12 running through the battery storage box 5 vertically.
13h for accommodating.

The electrode cord 14b drawn from the negative electrode 12b of the battery 12 through the inside of the groove 13h extends from the lower part of the electrical component storage section 11 to the front end of the battery storage box 5. The electrode cord 14b is fixed by the groove 13h without using a dedicated fixing clamper, and is stored inside the battery storage box 5, so that it is assembled with good appearance.

Both the negative electrode cord 14b and the positive electrode 2a electrode cord 14c drawn from the stagger switch 10b are connected to a starter motor (not shown) via a lead-out portion 11a at the front end of the battery box. I do.

As shown in FIG. 4, a box cover 5a forms a narrow front end 5b of the battery storage box 5 on the outside of the electrical component storage section 11 so as not to obstruct the operation of the occupant. Both end walls 13b and 13c at the front and rear portions of the battery holding portion 13 have protrusions 13i and 1 that partially protrude outward from the side surface of the battery 12.
3j.

The projections 13i of the end walls 13b, 13c,
13j has a function of protecting the battery against a force from the side of the vehicle body. Therefore, the side cover 1a can be formed thinner in place of the protection function of the side cover 1a of FIG. As a result, the weight of the side cover 1a having a large surface area can be reduced.

The battery storage box 5 is, as shown in FIGS.
Inside the side cover 1a, the inner side surface of the battery storage box 5 is close to the entire bending position of the chain case 4c, and is mounted to be inclined toward the center of the vehicle body. Therefore, the upper surface of the chain case 4c at full bending is closest to the inner surface of the battery storage box whose upper part is inclined toward the center and whose lower part is inclined outward in the vehicle width direction. Specifically, as shown in FIG. 5, the battery storage box 5
Is the oblique side a, and the other two sides b and c are vertical and horizontal.
The chain case 4c is fully bent within the region d formed by the lines.
Sometimes, it is arranged so that a part thereof is located. As described above, the battery storage box 5 is inclined such that the upper portion is located on the center side in the vehicle width direction, and the lower portion is inclined so as to be located on the outer side in the vehicle width direction. It is located on the outer side in the width direction, is inclined toward the center in the vehicle width direction as it goes upward, and is provided so as to follow the outer side surface of the battery storage box 5. The lower side of the battery storage box 5 is seated on the bracket 2h of the holder pipe 2d with the flexible hinge 5d of the box cover 5a interposed therebetween. On the upper side of the battery storage box 5, a locking portion 5e of a box cover 5a is provided.

During maintenance of the battery 12 and the like, the locking end of the box cover 5a is removed from the locking portion 5e while the side cover 1a is removed, so that the box cover 5a bends the flexible hinge 5d so as to be bent. The storage box 5 is opened outward and downward.

A stay 7a of a helmet holder 7 is welded between the two support legs 6a and 6b of the support portion of the pillion step 6 attached to the rear frame 2c shown in FIG. And attach it.

The helmet holder 7 is protected from external force by two support legs 6a and 6b of the pillion step 6 having high rigidity.
a is fixed to the body frame 2 and performs a theft prevention function.
