Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a fuse box mounting structure for a motorcycle.

(Prior art) Motorcycles have a front headlight,
Parts such as turn signals and alarms are provided, and parts such as tail lights, turn signals, and brake lights are provided at the rear. The operations of these parts are performed by switches mounted centrally on the handle. Each of these switches is
Furthermore, each of the above components is connected to an ignition switch via subfuses that are divided into several circuits, and the ignition switch is
It is connected to the battery attached to the rear of the vehicle via one main fuse.

By the way, the main fuse and each sub-fuse are conventionally arranged near the battery. Therefore, the wiring structure from the battery to each load is a single main cord that connects the battery at the rear of the vehicle through the main fuse to the ignition switch at the front of the vehicle, and from the ignition switch to the rear of the vehicle. Each sub-fuse is connected by multiple sub-cords to each sub-fuse attached to the handle, and each sub-fuse is connected to each switch installed on the handle at the front of the vehicle by multiple sub-cords, and from each switch to each load, each sub-cord is connected to Connected by cord.

However, in this conventional wiring structure, the battery, main fuse, and sub-fuse are installed at the rear of the car body, and each switch for operating each part is installed at the front of the car body, making the wiring longer than necessary. There was also the problem of complicated wiring. For this reason, wiring work in the assembly process of a motorcycle is complicated and requires a lot of time. Also, during maintenance work, when replacing subfuses,
There was a problem where the seat and side cover had to be removed.

Therefore, in order to simplify wiring, wiring work, and maintenance work, multiple subfuses are concentrated in one place, and these subfuses support the steering handle and the upper end of the front forks. It has been proposed that the device be placed in an openable/closable box provided on the top bridge (see Japanese Patent Laid-Open No. 54-64341).

However, many parts important to the operation of a motorcycle, such as a speedometer, tachometer, fuel gauge, turn signal, and ignition switch, are installed on or near the top bridge.
Therefore, when a fuse box is provided at this location, there is a problem in that the mounting positions of these parts are restricted accordingly. Moreover, when a fuse box is installed in an area where various parts are concentrated, the wiring must be threaded between each part, making the wiring work complicated and complicated during the assembly process, and reducing work efficiency. There were also problems.

On the other hand, it is also known that an integrated coupler box containing a coupler and a fuse is installed behind the alarm between the left and right alarms under the headlight. −14786
(see publication). In this case, the fuse and coupler are provided on the front and back sides of the box plate.

(Problem to be solved by the invention) However, in the case of the coupler box mentioned above, it has both a coupler and a fuse built in and is large, but it is located in a deep place between the left and right alarm devices. Therefore, it is difficult to assemble the alarm into the vehicle body unless the alarm is removed, and after assembly, it becomes difficult to inspect or replace the fuse. Also, since the fuse and coupler mentioned above are provided on the front and back sides of the box plate,
Even if waterproof measures are taken on the fuse side, the fuse will be adversely affected by water entering from the coupler side.

(Means for Solving the Problems) In order to solve these problems, the present invention provides a fuse-dedicated box that accommodates the fuses oriented in the vertical direction, in a position symmetrical to the alarm device with the head pipe at the center. In addition, by arranging the fuse box toward the front of the vehicle body on the opposite side of the side stand, the fuse box can be made smaller and easier to assemble to the vehicle body and the degree of freedom in design of the shape can be increased. The vehicle can be parked in an exposed state without being in the shadow of a headlight, making it easier to inspect and replace the fuse, and further improving waterproofness and vibration resistance.

That is, in the motorcycle fuse box mounting structure according to the present invention, in a motorcycle in which a fuse box and an alarm are disposed close to a headlight, the fuse box has an opening facing the front of the vehicle body, and The fuse box and the alarm are symmetrically arranged around the head pipe of the motorcycle, and the alarm is arranged symmetrically around the head pipe of the motorcycle. It is characterized in that it is arranged so as to be located on the side where the side stand is provided.

(Function) In the above fuse box mounting structure,
The fuse box can be exposed to the outside at the front of the vehicle without being hidden by the alarm, and since the opening facing the front of the vehicle has a lid, the lid can be opened to inspect the fuse. Not only is it easier to replace the fuse box, but even when the side stand is upright and the handlebars are all the way toward the side stand (a condition where the motorcycle can be parked stably), the fuse box is exposed instead of being hidden behind the headlight. This will not interfere with the inspection or replacement of the fuses mentioned above. Further, since the fuse is housed in the fuse box with vertical orientation, it is easy to obtain vibration resistance.

Thus, the above-mentioned fuse box is used exclusively for fuses, and the lid may be a single, simple one, making it easy to obtain waterproof properties and making it possible to reduce the size. This miniaturization, combined with the exposed external location at the front of the vehicle body, makes it easier to assemble the fuse box to the vehicle body, and furthermore, it is easier to organize the fuse box into a shape similar to that of other parts. In other words, there is a high degree of freedom in designing the shape, and it is possible to make it the same shape as the alarm, making it easier to improve the appearance of the vehicle body.

(Effect of the invention) Therefore, according to the invention, the box dedicated to the fuse, which accommodates the fuse in a vertically oriented manner, is placed in a symmetrical position with respect to the alarm with the head pipe as the center, and the fuse box is placed on the side stand. Since it is placed on the opposite side toward the front of the vehicle body, it increases the degree of freedom in the design of the vehicle body, and also allows serviceability such as inspection and replacement of fuses without compromising the waterproofness or vibration resistance of the fusebox. In addition, it is possible to improve the ease of assembling the fuse box to the vehicle body.
