Description

[Detailed Description of the Invention] This invention relates to a motorcycle that can illuminate the diagonally in front of the side on which the driver is turning when turning left or right.

Generally speaking, when turning left or right at night on a motorcycle, if the headlight is attached to the steering system, the direction is in front of the angle at which the steering wheel is turned, and if the headlight is attached to the body frame, the direction is in front of the direction of the vehicle body. The headlights emit light, but conventional motorcycles only have headlights, so if you want to illuminate the road surface in that direction before making a turn, you need to set a large illumination angle, and large lamps are needed. It was necessary.

This idea was made in view of the above circumstances,
The aim is to create a motorcycle that prevents unnecessary power consumption by turning on the necessary lamps when turning left or right at night.The main feature of this motorcycle is that the headlights are placed on the left and right positions of the front of the vehicle body in the direction of illumination. A cornering light is provided, which has an illumination angle facing forward left or forward right, respectively, and can be turned on when turning left or right, and a control circuit for turning on and off the cornering light is connected to the cornering light. This control circuit includes a speed sensor that detects the vehicle speed, and a control unit that keeps the cornering lights in an off state when the speed signal output from the speed sensor is less than a set value. It is in.

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

Figure 1 shows a side view of the motorcycle, and Figure 2 shows a front view of the same, where 1 is a body frame, 2 is an engine, and 3 is a front view of the motorcycle.
4 is a fuel tank, 4 is a seat, and 5 is a rear action unit that supports the rear wheel 6 in a cushioning manner. A front fork 7 supports a front wheel 8, and the front fork 7 is connected to a steering stem 9 rotatably fitted into a head pipe 1a at the front end of the vehicle body frame 1, and a bottom bridge 10 and a top bridge 11, as shown in FIG. A handle 12 is fixed to the top bridge 11. A headlight cover 14 containing a built-in headlight 13 is attached to the front fork 7.
Turn signals 15 are attached to both sides of 4 via arms 16.

A cornering light 17 having a forward leftward or forward rightward irradiation angle with respect to the irradiation direction of the headlight 13 is attached via a bracket 18 to a position below the bottom bridge 10 of the left and right front forks 7. This irradiation angle is indicated by θ in FIG. The details of the installation of the cornering light 17 will be explained with reference to FIG.
At the base end of the bracket 18, there is a cylindrical mounting portion 18b with one side split to form a tightening flange 18a.
The bracket 18 is attached to the front fork 7 by fitting the mounting portion 18b to the front fork 7 and tightening it with the bolt 19 and nut 20 with the buffer members 21 and 22 interposed.
is fixed. In this case, since the mounting portion 18b can be rotated arbitrarily on the front fork 7, the irradiation angle θ of the cornering light 17 is
can be adjusted freely. Note that the cornering light 17 is located on the inner side of the turn signal 15 in the vehicle body width direction.

FIG. 5 is a block diagram of a control circuit for the cornering light 17. The cornering light 17 is connected to a power source 24 via a control unit 23, and the control unit 23 includes manual cornering switches 25 attached to the left and right sides of the steering wheel 12. A turn signal switch 26, a steering wheel operation angle sensor 27, and a speed sensor 28 are also connected. When the left or right manual cornering switch 25 is manually operated, the control unit 23 turns on or off the left or right cornering light 17, respectively, and also turns the left or right cornering light 17 on and off automatically. That is, when the turn signal switch 26 is turned to the left (or right), the signal enters the control unit 23 and turns on the left (or right) cornering light 17, and when the left (or right) turn is completed, the steering wheel operation angle sensor 27 is turned on. is activated, a signal is sent to the control unit 23, and the turned-on cornering light 17 is turned off. When the speed signal from the speed sensor 28 is less than a preset constant value, the control unit 23 does not operate, and therefore the cornering light does not turn on when it is not necessary to turn on the cornering light, such as when the vehicle body is being pushed by hand.

Note that the steering wheel operation angle sensor 27 is a third
As shown in the figure, it is provided on the central lower surface of the bottom bridge 10, and when the rotation angle (that is, the steering angle) with respect to the head pipe 1a is returned within a certain angle, it issues a signal indicating the completion of a left or right turn as described above.

When driving the above-mentioned motorcycle at night and turning left, for example, the left manual cornering switch 2
5 or in conjunction with the turn signal switch 26, not only the illumination by the headlight 13 as shown in FIG. The cornering light 17 illuminates at the angle θ (its irradiation range is indicated by B), and the condition of the road surface on the left-turn side can be confirmed even before starting the left-turn operation. The same applies to right turns.

FIG. 7 shows another embodiment of the mounting structure of the cornering light 17 on the front fork 7, in which a substantially semicircular arc-shaped mounting portion 29b having tightening flange portions 29a at both ends is provided at the base end of the bracket 29. A tightening fitting 30 having a substantially semicircular arc shape and also having tightening flange portions 30a at both ends.
The front fork 7 is held between the mounting portion 29b and the tightening flange portions 18a and 30a of both.
By tightening the bolts 31 and nuts 32, the bracket 29 is fixed to the front fork 7 at a desired angle. This bracket 29
In this case, attachment to and detachment from the front fork 7 is easy.

Fig. 8 shows an example applied to a motorcycle in which a headlight is embedded in the fairing of the body mount.The fairing 33 is fixed to the vehicle body frame 1, the upper part is a transparent windscreen 33a, and the rear mirrors 34 are placed on the left and right sides of the windscreen 33a. , and turn signals 35, and a headlight 36 is embedded in the center of the front part. Cornering lights 37 are integrally provided on the left and right sides of the fairing 33, each having a forward leftward or forward rightward irradiation angle with respect to the irradiation direction of the headlight 36. Other points are the same as those in FIG. 1, and the same symbols are attached and explanations are omitted.

In the above-mentioned motorcycle, the fairing 33 does not move when the steering wheel is operated, and therefore the direction of illumination of the headlight 36 remains in front of the vehicle body regardless of the steering angle. The utility value is even higher.

In addition, in the embodiment, the cornering lights 17, 3
Although the turn signals 7 are arranged on the inside of the turn signals 15 and 35 in the vehicle width direction, they can also be arranged on the outside of the turn signals 15 and 35. Further, the height positions of the cornering lights 17, 35 and the turn signals 15, 35 can be reversed from those in the embodiment. Note that the cornering light according to the present invention can of course be applied to motor tricycles as well.

As explained above, according to the present invention, cornering lights are provided at the left and right positions of the front of the vehicle, with an illumination angle facing forward left or forward right relative to the illumination direction of the headlights, and can be turned on when turning left or right. A control circuit is connected to these cornering lights to turn them on and off. This control circuit is characterized by having a speed sensor that detects the vehicle speed, and a control unit that keeps the cornering lights off when the speed signal output from the speed sensor is below a set value. By turning on the lamps required when turning left or right when driving at night, it is possible to prevent unnecessary power consumption, and the cornering lights are prevented from turning on when the speed is below the set speed. Therefore, the cornering lights will not turn on when they are not needed, such as when the driver gets off the vehicle and is pushing it around by hand, which further enhances the above-mentioned effects.
