Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a switch mounting structure for a motorcycle.
[0002]
[Prior art]
The motorcycle is provided with a main switch (ignition switch) having a lock cylinder capable of turning on / off the main power source of the engine ignition circuit (ignition) and electric auxiliary equipment by inserting an operation key. This main switch is generally arranged in the vicinity of the handlebar so that the rider can easily operate in the riding state.
[0003]
As a specific example, for example, there is a handle holder in which a main switch is attached via a bracket to a handle holder that fixes a handlebar to a steering head.
[0004]
[Problems to be solved by the invention]
However, when the main switch is mounted in the above-described manner, the main switch faces upward, and rainwater may enter the main switch from the operation key insertion port via the operation key inserted into the switch, such as in rainy weather. is there. If rainwater enters the main switch, rust and freezing will occur, causing malfunction of the main switch.
[0005]
On the other hand, the operation key insertion port of the main switch faces downward from the vertical to prevent rainwater from entering the main switch via the operation key, but the operation key is released due to vibration during traveling. Cause a bug.
[0006]
The present invention has been made in consideration of the above-described circumstances, and an object of the present invention is to provide a switch mounting structure for a motorcycle that prevents intrusion of rainwater or the like into the switch.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problem, a switch mounting structure for a motorcycle according to the present invention is provided with a switch having a lock cylinder on a handle bar for steering a front fork that supports a front wheel. In addition, in the motorcycle, the handlebar is formed by extending a horizontal portion formed in the center thereof, a rising portion rising upward from the left and right of the horizontal portion, and both ends of the rising portion extending in the left-right direction. A grip portion and a bridge member erected substantially in the middle of the rising portion, and in the vicinity of the rising portion on the inner side in the vehicle width direction of the curved corner portion of the horizontal portion and the rising portion of the handlebar A plate-like bracket extending around the front of the bridge member is provided between the handle bar and the bridge member, while the switch is locked It is placed on the bracket directly below the bridge member in the vehicle width direction inside of the handlebar rising part so that the insertion port of Linda's operation key is directed rearward in the traveling direction. The handlebar is covered with a rising portion and a bridge member to prevent rainwater and the like from entering the operation key insertion port.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
FIG. 1 is a left side view showing an example of a motorcycle to which the present invention is applied. As shown in FIG. 1, this motorcycle 1 has an underbone type body frame (not shown), and supports a front wheel 5 together with a handlebar 3 and a front fender 4 on a head pipe 2 provided on the front head thereof. A front fork 6 is pivotally attached to the left and right to be steerable.
[0011]
An engine 7 is mounted at the center lower part of the vehicle body. A chain case 8 that also serves as a swing arm extends rearward from the engine 7, and a rear wheel 9 that is a drive wheel is pivotally supported at the rear part. Further, an operation seat 10 is provided above the chain case 8, and a leg shield 11 that covers the upper and left and right sides of the engine 7 is disposed at the front lower portion of the operation seat 10.
[0012]
FIG. 2 is a view taken in the direction of arrow II in FIG. 1 and shows a first embodiment of the present invention. As shown in FIG. 2, the handle bar 3 is fixed to an upper bracket 12 provided at the upper ends of the left and right front forks 6 via a handle holder 13. The handlebar 3 is fixed to the upper bracket 12 at a horizontal portion 3a formed at the center thereof. The left and right sides of the horizontal portion 3a rise upward and form a rising portion 3b. Furthermore, both ends of the rising portion 3b extend in the left-right direction to form the grip portion 3c. The handle bar 3 is configured by, for example, integrally forming a metal pipe material. Further, a bridge member 14, which is another member constituting the handle bar 3, is installed between the handle bars 3 between the substantially central portions of the left and right rising portions 3 b.
[0013]
By the way, the motorcycle 1 includes a main cylinder having a lock cylinder 16 (to be described later) capable of turning on / off a main power source of an ignition circuit (ignition) of an engine 7 and an electrical accessory (not shown) by inserting an operation key 15. A switch 17 is provided. The main switch 17 is attached via a plate-like bracket 18 serving as an auxiliary device in the vicinity of the rising portion 3b on the inner side in the vehicle width direction of the curved corner portion of the horizontal portion 3a and the rising portion 3b of the handlebar 3. At this time, the main switch 17 is arranged so that the operation key insertion port 19 of the lock cylinder 16 faces backward in the traveling direction.
[0014]
FIG. 3 is an enlarged view of the vicinity of the main switch 17. 4 is a cross-sectional view taken along line IV-IV in FIG. As shown in FIGS. 3 and 4, the bracket 18 for attaching the main switch 17 has a lower portion welded, for example, in the vicinity of the inside of the curved corner portion of the horizontal portion 3 a and the rising portion 3 b of the handlebar 3, and the bridge member 14. It extends in the upper direction around the front. Further, the bracket 18 is bent rearward in the vicinity of the front of the bridge member 14.
[0015]
A lock cylinder 16 of the main switch 17 is attached between the handlebar 3 and the bridge member 14 of the bracket 18. The main switch 17 is arranged so that the insertion port 19 of the operation key 15 of the lock cylinder 16 is directed rearward in the traveling direction. At this time, the insertion port 19 of the operation key 15 is disposed directly below the bridge member 14. Further, a portion of the bridge member 14 directly above the operation key insertion opening 19 is recessed upward to form an escape portion 14a so as not to hinder the operation of the operation key 15. And the holder 20 of the helmet which is not shown in figure, which is another auxiliary device, for example is attached to the upper end part of the bracket 18. At this time, the helmet holder 20 protrudes rearward so as to cover the insertion port 19 of the operation key 15 from above.
[0018]
Next, the operation of this embodiment will be described.
[0019]
By disposing the insertion port 19 of the operation key 15 toward the rear in the traveling direction and arranging the insertion port 19 so that the outer side and the upper side in the vehicle width direction are covered with the rising portion of the handlebar and the bridge member , special protection is provided. Intrusion of rainwater, snow, or the like into the insertion port 19 can be prevented without providing a device. As a result, the rust and freezing inside the lock cylinder 16 due to these moisture are prevented, and the main switch 17 does not malfunction.
[0020]
Further, since the handle bar 3 is disposed at the lower part and the side part of the main switch 17, it is possible to prevent the main switch 17 from being damaged by hitting a leg or the like when the rider gets on and off.
[0021]
