BACKGROUND OF THE INVENTION
The present invention relates to a handlebar switch having a switch case that is fixed to a steering handlebar for a vehicle such as a two-wheeled vehicle and capable of operating various electrical components.
[0002]
[Prior art]
In general, a handlebar of a motorcycle is provided with a grip grip at the left end and a throttle grip at the right end, and a switch case is fixed in the vicinity of these grips. Such a switch case is composed of upper and lower halved parts, and these upper and lower halved shapes are matched while holding the handle bar, and are fixed by bolting.
[0003]
The switch case constitutes a housing for a handlebar switch, and a fixed contact provided on the base is disposed inside, and a movable contact that can be contacted or separated from the fixed contact is a switch knob. It is connected to. This switch knob is for operating various electrical components mounted on the motorcycle. For example, the switch case on the left side has a dimmer switch knob for switching the vehicle headlamp, and a blinker for the vehicle blinker. A turn signal switch knob, a horn switch knob for sounding a horn, a passing switch knob for passing, and the like are provided.
[0004]
Conventionally, the turn signal switch knob is swingably attached to the upper surface side of the base, and the tip is suspended to the lower surface side of the base, and the interlocking member formed with the movable contact is interlocked with the protruding end. The switching operation with the fixed contact was performed. That is, the turn signal switch knob is attached to the upper surface of the base, while the fixed contact is fixed to the lower surface of the base, and the movable member is brought into contact with the fixed contact by operating the interlocking member on the lower surface side of the base. Or they were separated.
[0005]
[Problems to be solved by the invention]
However, in the conventional handlebar switch described above, the switch components (the switch member including the turn signal switch knob and the movable contact) are also provided on the upper surface of the base, so that rainwater or the like enters the switch case. When this occurs, the water reaches the switch member disposed on the upper surface of the base, and through an opening or the like for connection with a component (the interlocking member in the above prior art) disposed on the lower surface. Since the switch member disposed on the lower surface is also reached, the contact portion of the switch is immersed in water, which may cause an electrical failure.
[0006]
That is, the switch case is provided with movable parts such as a dimmer switch knob on the upper surface side, so that a large clearance is provided for the movement, and the mating surface of the half-shaped parts and the handle Rainwater is easy to enter from the gap with the outer peripheral surface of the bar. In particular, in the case of a motorcycle, since the switch case is exposed to the outside, the intrusion of rainwater or the like is unavoidable.
[0007]
When water reaches the base due to such water immersion, the fixed and movable contacts located on the lower side of the base are immersed in water through the openings that penetrate the upper and lower surfaces of the base, and the life of the switch is shortened. There was a risk of becoming. In addition, it is conceivable to attach a waterproof cover between the switch case and the handlebar disposed on the lower side of the half-shaped part, but in that case, it is necessary to newly dispose the cover. Therefore, there is a problem that the number of parts increases and the assembly process and lead time also increase.
[0008]
The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a handlebar switch that can prevent electrical problems from occurring due to contact points immersed in water without increasing the number of components.
[0009]

[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The handlebar switch according to the present embodiment is fixed adjacent to a grip grip attached to the left end of the handlebar in a motorcycle, and can operate various electrical components mounted on the motorcycle. As shown in FIG. 3, a pair of halved parts composed of an upper switch case 1a and a lower switch case 1b are matched to form a switch case 1 as a housing.
[0015]
A dimmer switch 2 and a passing switch 3 are formed in the upper switch case 1a. Further, semicircular arc shapes 1aa and 1ab that can coincide with the outer peripheral surface of the handlebar in the two-wheeled vehicle are formed at the left and right ends of the upper switch case 1a, and the semicircular arc shape 1ba formed at the left and right ends of the lower switch case 1b. And 1bb, the outer peripheral surface of the handle bar can be sandwiched from above and below.
[0016]
A turn signal switch 4 and a horn switch 5 are formed in the lower switch case 1b. Further, the semicircular arc shapes 1ba and 1bb described above are formed on the left and right ends of the lower switch case 1b.
[0017]
Here, the turn signal switch 4 has a turn signal switch lever 10 having a turn signal switch knob 4a formed at the tip thereof, and the turn signal switch lever 10 can be swung in the left-right direction. The turn signal switch lever 10 is swingably attached to a base 6 fixed in the lower switch case 1b with screws B1 and B2 (see FIG. 4). As shown in FIG. 9, the base 6 has a curvature whose upper surface 6a substantially matches the outer peripheral surface of the handlebar, and is made of a material such as hard resin that does not allow moisture such as raindrops to pass downward. ing.
[0018]
That is, when the base 6 is fixed to the handlebar with the base 6 assembled in the switch case 1, the upper surface 6a of the base 6 is configured to coincide with the outer peripheral surface of the handlebar. The water that has entered the switch case 1 from the mating surface with the bar does not reach the lower surface 6 b side of the base 6. In addition, the code | symbol 6d in the figure has shown the screw seat part which is integrally formed with the base 6, and penetrates the screw | thread for assembling the said base 6 in the switch case 1 inside.
[0019]
On the other hand, as shown in FIG. 5, a housing 6c is integrally formed on the lower surface 6b side of the base 6, and a terminal block 7 having a fixed contact 7a and a slide member 8 having a movable contact 8a in the housing 6c. Are assembled. A pair of claws 7b are formed on the side surface of the terminal block 7, and these claws 7b are configured to be fixed to the housing 6c by being fitted and locked in locking holes 6ca formed in the housing 6c. ing. The slide member 8 is assembled so that the movable contact 8a slides facing the fixed contact 7a in the terminal block 7.
[0020]
A cylindrical connecting tube portion 8b is formed at the upper end of the slide member 8, and the connecting projection 9b of the interlocking member 9 is fitted into the connecting tube portion 8b. The interlocking member 9 operates the movable contact 8a in conjunction with the turn signal switch lever 10, and is formed with an insertion hole 9c through which the screw N is inserted and an insertion hole 9a through which the protrusion 10a is inserted. . The turn signal switch knob 4a, the turn signal switch lever 10, the slide member 8, and the interlocking member 9 constitute the switch member of the present invention (having a movable contact that can be contacted or separated from the fixed contact of the base). ing.
[0021]
Further, the turn signal switch lever 10 is formed in an arc shape so that the turn signal switch knob 4a is formed at the tip and the tension ball B urged by the spring S can slide on the base end. And the long hole 10b which penetrates the screw | thread N which penetrated the penetration hole 9c is formed, and it has the projection part 10a which protruded the predetermined dimension below.
[0022]
Further, as shown in FIG. 6, the insertion hole 9a of the connecting member 9 has a pair of inclined surfaces 9b and 9c formed at both lower corners, and the turn signal switch knob 4a and the turn signal switch lever 10 are screwed N When the rocker is swung to the left or right around the center, the protrusion 10a comes into contact with the inclined surface 9b or 9c so that the interlocking member 9 can be operated. For example, when the turn signal switch knob 4a is operated to swing the turn signal switch lever 10 in the direction of the arrow in the figure, the protrusion 10a comes into contact with the inclined surface 9c and the interlocking member 9 is centered on the screw N. As shown in FIG.
[0023]
At this time, the slide member 8 slides to the left with respect to the terminal block 7, and the movable contact 8a comes into contact with the predetermined fixed contact 7a at that position, and the corresponding blinker blinks. Further, in such a switching state, since the base end of the turn signal switch lever 10 formed in an arc shape is given a restoring force from the spring S via the tension ball B, the driver can turn the turn signal switch knob 4a. When the finger is released, only the turn signal switch lever 10 returns to the original position (initial position) (see FIG. 8).
[0024]
To cancel the blinking operation of the blinker and stop the blinking operation, the turn signal switch knob 4a is pressed in the direction of arrow a in FIG. By this pressing operation, the turn signal switch lever 10 slides in the direction a, and the protrusion 10a presses the other inclined surface 9b of the interlocking member 9, so that the interlocking member 9 is directed in the direction of the arrow b. A force (moment) is generated and swung to the initial position.
[0025]
The movement of the interlocking member 9 to the initial position causes the slide member 8 to slide to the original position (neutral position), and the movable contact 8a that contacts the predetermined fixed contact 7a is separated from the state shown in FIG. (Initial state). Even when the swing operation is performed in the direction opposite to the arrow in FIG. 6, the same switching action as described above is performed, and the blinker corresponding to the swing direction flashes.
[0026]
According to the handlebar switch having the above-described configuration, all the components of the turn signal switch 4 are provided on the lower surface side of the base 6, and the turn signal switch lever 10 and the movable contact 8 a interlocked therewith are provided below the base 6. Since it operates, no opening is formed from the upper surface to the lower surface of the base 6, and the clearance formed between the switch knob 1 such as the dimmer switch 2 and the passing switch 3 and the switch case 1 enters from above. Raindrops or the like are prevented from dropping further downward from the base 6.
[0027]
Accordingly, it is possible to prevent rust caused by the fixed contact 7a and the movable contact 8a being immersed in water, or to prevent an electrical failure, and a resin base that has been conventionally used can be used. Since it can be used as it is also as a waterproof means, it is possible to avoid an increase in the number of parts. Further, since the terminal block 7 with the fixed contact 7a and the slide member 8 with the movable contact 8a formed therein are accommodated in a housing 6c formed integrally with the lower portion of the base 6, a separate housing is used. Compared with what is provided, the manufacturing cost can be reduced and the waterproof effect can be further improved.
[0028]
Although the handlebar switch according to the present embodiment has been described above, the present invention is not limited to this. For example, in addition to a turn signal switch, the handlebar switch is applied to various switches disposed in a switch case. Can be achieved. In this embodiment, the upper surface of the base has a curvature that substantially matches the outer peripheral surface. However, the upper surface does not necessarily have to have a curvature. For example, the upper surface of the base is substantially flat or extends from the end to the center. It is also possible to have a convex curvature. However, by making the upper surface of the base as a curved surface as in this embodiment, when assembled to the handlebar, water reaching the upper surface of the base can be dripped with directionality, and the direction in which the water drops It is possible to avoid the formation of fixed contacts and switch members.
[0029]
Furthermore, even when applied to a turn signal switch as in the present embodiment, the blinker blinking canceling mechanism may take other forms. That is, in this embodiment, blinker blinking is canceled by pressing the turn signal switch knob, but it may be canceled by operating a separate switch or the like.
[0030]
Furthermore, in this embodiment, the present invention is applied to a handlebar switch in a switch case fixed to the handlebar of a two-wheeled vehicle. However, the switch is fixed to the handlebar in another vehicle (for example, a snow vehicle or ATV). It may be applied to a power switch case.
[0031]
【The invention's effect】
According to the first aspect of the present invention, it is possible to avoid raindrops or the like that have entered from above reaching the contact point disposed below the base, so that the contact point is immersed in water and causes an electrical failure. Can be prevented. In addition, since the base used conventionally can also be used as it is as a waterproof means, it is possible to avoid an increase in the number of parts. Further, since the housing for assembling the fixed contact and the switch member is integrally provided on the lower surface of the base, the manufacturing cost can be reduced and the waterproof effect can be further improved compared to the case where a separate housing is provided. be able to.
[0032]
According to the invention of claim 2, since the housing surrounds the sides of the fixed contact and the movable contact with the wall suspended from the lower surface of the base, the contact is immersed in water, causing an electrical failure. Can be prevented.
[0033]
According to the invention of claim 3, since the upper surface of the base has a curvature that substantially matches the outer peripheral surface of the handlebar, the direction of the water that has reached the upper surface of the base when the handlebar is assembled. Can be dropped. Therefore, it is possible to avoid the formation of a fixed contact or a switch member in the direction in which water drops, and the waterproof effect can be further improved.
[0034]
According to the invention of claim 4, since the interlocking member in the turn signal switch is also provided on the lower surface of the base, the waterproof effect can be further improved. That is, the turn signal switch may include a mechanism for canceling blinking of the blinker in addition to the operation of swinging the switch lever in the left-right direction, and thus may have a complicated contact structure via an interlocking member. In many cases, all such complicated structures are provided on the lower surface of the base to provide a waterproof effect.
