Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in the arrangement of electrical components installed in motorcycles, particularly ignition coils and ignition units.

The length of the connection between the ignition coil and ignition unit used to ignite an internal combustion engine should be short to prevent voltage drop. Especially in the case of a CDI ignition unit, the primary current flowing through the ignition coil is large. The shorter the connection length between the ignition coil and CDI unit, the lower the voltage drop. Therefore, it is preferable to place the ignition coil and ignition unit close together to shorten the distance between them. However, in the case of motorcycles, the space for placing electrical components is limited due to the structure of the vehicle body, so it is not possible to However, there was a limit to how short the distance between the ignition coil and ignition unit could be.

This idea was created in view of the above circumstances.
The aim was to focus on the frame structure of motorcycles, which has reinforcing plates fixed to both sides of the front of the main pipe and down pipe, and to make effective use of the space in the reinforcing plates to bring the ignition coil and ignition unit closer together. To provide a structure for arranging electrical components for a motorcycle, which allows electrical components to be arranged such that the wire connection length can be made shorter than before.

In order to achieve this purpose, the present invention attaches an ignition coil to the end of the reinforcing plate, houses the ignition unit in the space between the left and right reinforcing plates, and further restricts the downward movement of the ignition unit. The gist is that the reinforcing plate is provided with a regulating plate for this purpose.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a side view of a body frame of a motorcycle to which the present invention is applied.
, one main pipe 3 extending rearward from the top of this, and one main pipe 1 extending backward and downward from the bottom.
A main down pipe 4, left and right down pipes 5, 5 connected to it, left and right center pipes 6, 6 connected to the main pipe 3, and left and right seat pipes 7, 7 connected to the middle part of these, respectively. , left and right rear pipes 8, 8 connected to the middle part of these, respectively.
and left and right connecting plates 9, 9 that connect the lower down pipe 5, the center pipe 6, and the rear pipe 8. Reinforcement plates 10, 10 are fixed to the left and right sides of the front portions of the main pipe 3 and down pipe 4.

In the space surrounded by the main pipe 3, the down pipe 4, the down pipe lower 5, the center pipe 6, and the connecting plate 9 behind the reinforcing plate 10 of the vehicle body frame 1, an insulator is installed via the brackets 20... The illustrated internal combustion engine is installed.

Note that the reinforcing plate 10 is provided with a stay 11 for attaching a fuel tank (not shown) installed over the main pipe 3.

The rear edge 12 of this reinforcing plate 10 is formed into a side arc shape facing forward, and in the embodiment, a protruding piece 13 is integrally formed on the upper part of the rear edge 12 of the right reinforcing plate 10. An L-shaped bracket plate 14 is welded to the inner surface. On the other hand,
A regulation plate 16 is welded to the inner surface of the left reinforcing plate 10 at approximately the center thereof. This regulation plate 16 is formed by bending an L-shaped mounting piece 18 that stands up on the left side of the front part of the flat plate part 17, and further by hanging a regulation piece 19 in an L-shape from the rear end of the flat plate part 17. The flat plate part 17 is made parallel to the down pipe 4, and the mounting piece 18 is welded to the inner surface of the reinforcing plate 10. The configuration of the main parts described above is shown in Figure 2.

Then, as shown in FIG. 2, the ignition coil 21 is hooked and supported on the L-shaped horizontal piece 15 of the bracket plate 14 facing below the main pipe 3, and the flat plate of the regulation plate 16 between the reinforcing plates 10, 10 A CDI type ignition unit 22 is housed in a space below the section 17 via a rubber case 23.

As shown in FIG. 3, the rubber case 23 has an opening 24 on the front surface, an extension piece 25 protruding forward from the lower edge of the opening 24, and a large number of protrusions 26 formed on both left and right sides. Also, in the center of the width direction of the bottom surface is 3
In addition, a cord outlet 28 is formed in the right half of the rear surface as shown in FIG.

The box-shaped ignition unit 22 is fitted into the rubber case 23 from the front opening 24, and the rubber case 23 is inserted into the internal space from the front of both reinforcing plates 10, 10, and the regulation plate 16 is inserted into the rubber case 23.
The rubber case 23 is inserted between the flat plate part 17 and the down pipe 4, and the rubber case 23 is pushed in until the rear surface contacts the regulating piece 19. Here, as shown in FIG. 4, the protrusions 26 on both sides of the rubber case 23
The protrusions 27 on the lower surface are in pressure contact with the down pipe 4.

In this way, the ignition coil 21 is attached to the rear edge 12 of the reinforcing plate 10, and the ignition unit 22 is housed in the space between the two reinforcing plates 10, 10, so that the space within the width of the front part of the main pipe 3 and down pipe 4 is The ignition coil 21 and the ignition unit 22 can be arranged close to each other by effectively utilizing the ignition coil 21 and the ignition unit 22, and therefore the length of the wire connecting the ignition coil 21 and the ignition unit 22 can be shortened. Furthermore, reinforcement plate 1
Since the regulating plate 16 is provided at the ignition unit 0, the regulating piece 19 can prevent the ignition unit 22 from falling off downward.

Furthermore, with the above-described arrangement structure, the ignition coil 21 and the ignition unit 22 fit within the width of the front part of the vehicle body frame 1 and do not protrude outward, so that the fuel tank can also be formed slim.

By the way, if a rectangular down pipe 40 is adopted as shown in FIG. 5, the ignition unit 2 placed on the down pipe 40 can be
The sitting position of No. 2 becomes stable.

In addition, instead of the rubber case 23, as shown in FIGS. 6 and 7, the right side to the upper and lower surfaces of the ignition unit 22 are held by a rubber cushion (sponge) 31 having a U-shaped longitudinal section, and the left side of the ignition unit 22 is The front and rear surfaces are held by rubber cushions (sponge) 32 having an L-shaped cross section, and the ignition unit 22 is assembled with the two reinforcing plates 10, 10 in the same manner as described above by interposing the two rubber cushions 31, 32. It may be stored in the space between them.

As is clear from the above explanation, according to the electrical component arrangement structure of the present invention, the ignition coil Since the ignition unit and the ignition unit can be placed close to each other, the length of the connection between the ignition coil and the ignition unit can be significantly shortened, and voltage drop can therefore be prevented.
