Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an electrical component mounting structure for a motorcycle.

(Prior Art) Recently, motorcycles have come to be equipped with many electrical components for engines, instruments, etc.

These are placed somewhere in the surplus space of the vehicle body.

(Problems to be Solved by the Invention) 'By the way, the extra space in the car body is limited and small, so it is not easy to install these electrical components, and the electrical wiring attached to these electrical components is also difficult. It is not easy, and even if the electrical components are installed in the surplus space and electrical wiring is provided to them,
There is a possibility that these parts are easily visible and the appearance of the vehicle body is deteriorated.

(Object of the Invention) This invention has been made in view of the above-mentioned circumstances, and it is intended to facilitate the installation of electrical components on the vehicle body and the accompanying electrical wiring, and to provide a method to facilitate the installation of electrical components on the vehicle body and the accompanying electrical wiring. To maintain the appearance of a vehicle body in good condition even when electrical components are installed and electrical wiring is performed.

(Structure of the Invention) The present invention for achieving the above object is characterized in that a motorcycle is provided with a pair of left and right main frames each having a substantially C-shaped cross section and openings thereof facing each other.
A bracket is attached to the opening side of the main frame, and electrical components are supported on this bracket.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 2, l is a motorcycle, and the front part of the body frame 2 rotatably supports a front fork 3. A front wheel 4 is supported at the lower end of this front fork 3, and A handle 5 is attached to the upper end.

On the other hand, a rear arm 7 is pivotally supported at the rear of the vehicle body frame 2 so as to be vertically swingable, and a rear wheel 8 is supported at the swinging end of the rear arm 7. Further, the vehicle body frame 2 supports an engine 9, and this engine 9 supports the rear wheels 8.
to drive. 10 is a fuel tank, 11 is a seat, and 12 is a side cover.

To explain the vehicle body frame 2 in more detail with reference to each figure, the vehicle body frame 2 has a head vibrator 14 at its front portion, and this head pipe 14 supports the front fork 3. A pair of left and right main frames 15.1 extend rearward and downward from the head pipe 14.
A down tube 16 is installed at the front and rear ends of each main frame 15, and the engine 9 is installed in a space surrounded by the main frame 15 and the down tube 16.
It is arranged.

The main frames 15, 15 are made of sheet metal, and each has a substantially C-shaped cross section, with openings 17 facing each other. This main frame 15.15 is a so-called delta frame, and is employed to improve the external appearance, suppress an increase in weight, and improve strength.

Various electrical components are attached to the opening 17 side of the main frame 15.

That is, as shown in FIGS. 1, 3, and 4, a first bracket 19 is welded to the upper and lower edges of the opening 17 in the left main frame 15.
A pair of upper and lower support pieces 20.degree. A box-shaped rubber elastic body 21 that opens toward the front of the vehicle body is fitted into this support piece 20.20.
1 is fitted with an ignition unit 22 which is an electrical component for the engine 9, and an elastic body 21 elastically holds the ignition unit 22.The ignition unit 22 is attached to a flywheel magneto or spark plug (not shown). The connecting wire harness 23 once protrudes from the ignition unit 22 toward the front of the vehicle body, and then is folded back toward the rear.
It is wired along the bottom surface inside the main frame 15.

Further, as shown in FIGS. 1 and 5, a rectufire regulator 25, which is an electrical component, is provided opposite the ignition unit 22 in the vehicle width direction.

The rectufire regulator 25 is screwed by a bolt 27 to a second bracket 26 welded to the upper and lower edges of the opening 17 in the right main frame 15. The second bracket 26 is bent diagonally upward, and the bolt 27 is perpendicular to this. Therefore, the bolt 27 can be operated from above the small body frame 2, and therefore, the work of screwing in or loosening the bolt 27 can be easily performed. In addition, this Rectufire Reculator 25
A wire harness 23 extending from the ignition unit 22 also
It is wired in the same way as in the case of .

Furthermore, as shown in FIG. 3 and FIGS. 6 to 8, a flasher relay 28 as an electrical component is provided behind the ignition unit 22. This flasher relay 28 is attached to the left main frame 15 in the following manner.

That is, a third bracket 30 is welded to the lower opening edge of the opening 17 in the main frame 15 so as to protrude upward, and a cylindrical rubber elastic body 31 penetrating vertically is fitted to this protruding end. It's a dress. The flasher relay 28 is fitted into this elastic body 31, and the elastic body 31 elastically holds the flasher relay 28.

In the above case, the upper and lower middle parts of the third bracket 30 are once bent toward the inside of the main frame 15;
A part of the flasher relay 28 attached to the protruding end of the bracket 30 is housed within the main frame 15.

Therefore, the space within the main frame 15 is effectively utilized. Further, the lower end surface of the flasher relay 28 is in contact with the upper surface of the bent portion 30a of the third bracket 30, thereby preventing the flasher relay 28 from being removed from the elastic body 31 and falling. A wire harness 23 extending from the flasher relay 28 is also wired in the same manner as the ignition unit 22.

In the above case, the first bracket 19 and the third bracket 30
are located far apart in the front and rear, so each wire harness 2
The wiring work in step 3 can be facilitated by inserting the worker's hands and tools into the space between the two, making effective use of this space. Also, each bracket above)'! 9
, 26 and 30, the wire harness 23 is attached to the main frame 15
It prevents it from falling away from within.

(Effects of the Invention) According to the present invention, in a motorcycle provided with a pair of left and right main frames each having a substantially C-shaped cross section and openings thereof facing each other, a bracket is attached to the opening side of the main frame. Because the electrical equipment was supported by the bracket,
Part or all of the electrical components and their accompanying electrical wiring can be accommodated within the main frame. Therefore, since the space within the main frame is effectively utilized, it becomes easy to arrange electrical components on the vehicle body and to wire them incidentally. Moreover, since the main frame usually extends linearly in the longitudinal direction of the vehicle body and has few bends, the space within the main frame is suitable for electrical wiring.

Further, in the present invention, the brackets and electrical components are located on the opening side of the main frame, that is, on the inner surface of the main frame in the vehicle width direction, so that the main frame prevents them from being seen externally.

Therefore, the appearance of the vehicle body is maintained well.
