Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handle switch device for a two-wheeled vehicle.

In a motorcycle, as a method of illuminating the handlebar switch device at night, an illumination lamp is provided on the hanging part of the rearview mirror attached to the handlebar. A method for illuminating the operation surface of a switch case that was exposed to light was discovered in Japanese Patent Publication No. 5
It is disclosed in the publication No. 6-539348.

In such lighting methods, since the light source is external lighting and is located far from the operation surface of the switch case, unnecessary areas are illuminated, making it difficult to see the necessary areas, and the illuminance becomes uneven. In order to increase the brightness, the light source luminous intensity was increased. Furthermore, the illumination angle changes due to adjustment of the rearview mirror, making it impossible to obtain desired illumination.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a handlebar switch device for a two-wheeled vehicle that can reliably illuminate only necessary parts of a switch case with uniform illuminance.

In the handlebar switch device for a two-wheeled vehicle according to the present invention, a light source is provided within the switch case, and a light guide plate is provided between the outer peripheral edge of the switch operator and the switch case, at least a portion of which faces into the switch case. It becomes.

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

1, 2, and 3 are a front view, a side view, and a plan view of a motorcycle equipped with a handlebar switch device according to the present invention. In Figures 1 to 3, 1 is the vehicle body frame, 2 is the front fender, 3 is the front wheel, 4 is the front fender, 5 is connected to the frame 1 via a link (not shown) at the front, and a shock absorber at the rear. swing type power units each pivotally connected to the frame 1 via a container (not shown);
6 is the rear wheel. Further, 7 is a seat, 8 is a handle for steering the front wheels 3, and 9 is a front grill, in which blinker lamps 10, 10 and a headlamp 11 are embedded. A low step floor 12 is arranged between the front wheels 3 and the rear wheels 6, and a leg shield 13 is provided in front of this step floor 12, and a rear body 14 is provided in the rear thereof.

Handle switch devices 17 and 18 are arranged on the inner sides of the right grip 15 and left grip 16 of the handle 8, respectively.

4 to 8 show an embodiment of the present invention applied to a handle switch device 17 on the right grip 15 side. In FIGS. 4 to 8, a switch case 20 is arranged inside the right grip 15 of the handle pipe 19. As shown in FIGS. The switch case 20 is made up of a front case 21 and a rear case 22 that are connected to each other across the handle pipe 19 in the longitudinal direction of the vehicle body, and the front case 21 and the rear case 22 are made of aluminum, hard resin, or the like. Inside the switch case 2o, a riding switch 23 and a starter switch 24 are disposed above and below the handle pipe 19, respectively.
and 24 pushco type operators 25 and 2G are provided protrudingly. The lighting switch operator 25 has a substantially circular shape, and as is particularly clear from FIG. 7, the operation part (top surface) is a sloped surface that is higher on the right grip 15 side than on the vehicle center side.Starter switch The operator 26 has a long rectangular shape in the axial direction of the handle pipe 19, and its end on the right grip 15 side protrudes.

Between the actuator 23a of the lighting switch 23 and its operator 25, there is a substantially dogleg-shaped swing arm 2 whose one end is swingably supported relative to the switch case 20.
7 is interposed, and the swinging arm 27 swings around the swinging fulcrum 27a by pressing the operator 25, and actuates the actuator 23a at the other end. The lighting switch 23 changes the headlight position, small light position and Δ](OFIF) every time the actuator 23a operates.
) It has a rotary to switch configuration that can sequentially take three positions. Above the lighting switch 23,
A display board 28 is rotatably provided which sequentially displays the three positions in conjunction with the lighting switch 23. As shown in FIG. 9, the display board 28 is made of a translucent material such as polycarbonate and has a substantially same Sendai shape, and letters and symbols representing the three positions are attached to the slopes thereof. A display hole 29 is formed in the upper inclined surface 20a of the switch case 20, and the characters and symbols on the display board 28 can be confirmed from the outside through the display hole 29.

In the switch case 20, between the outer peripheral edge of the operator 25, 26 and the rear case 22, as is clear from FIGS. 5 and 6, there is a guide made of a translucent material such as polycarbonate. The light plate 31 is connected to the outer surface of the rear case 22.
Further, the inner part of the light guide plate 31 is attached to the inner surface of the rear case 22 near the periphery of the operating elements 25 and 26. Inside the switch case 20, there are controls 25 and 26 located on the front side of the vehicle body relative to the handle pipe 19.
An illumination light source 30 is provided at a position closer to the center of the vehicle body, and this light source 30 illuminates the display panel 28 made of a translucent material, and also directs the light from the light source 30 to the light guide plate 31.
The operator 25.26 is guided to the outer surface of the rear case 22 by
Only the outer periphery of the area is illuminated. As a result, the characters/symbols of the display section and the outer periphery of the controls 25 and 26 emit light, improving visibility and operability at night.

In the above embodiment, a case has been described in which the case is applied to the handle switch device 17 on the right grip 15 side, but the above embodiment also applies when applied to the handle switch device 18 on the left grip 16 side (see FIG. 3). The same effect can be obtained. Furthermore, the present invention is not limited to application to handle switch devices for motorcycles, but can also be applied to handle switch devices for tricycles and the like.

As described above, according to the present invention, a light source is provided within the switch case, and a light guide plate, at least a portion of which faces into the switch case, is provided between the outer peripheral edge of the switch operator and the switch case. With this structure, only the necessary areas can be illuminated, and since the light source is close, uniform and sufficient illuminance can be obtained even if the light source luminance is small. Furthermore, since the lighting is internal, there is no change in the lighting direction due to positional changes of external equipment such as rearview mirrors, unlike in the conventional case. Furthermore, since the light source is close to the switch, wiring of the light source power source is easy.
