Description

  The present invention relates to a dimmer switch for switching between a front irradiation lamp and a lower irradiation lamp included in a vehicle.

  In general, a dimmer switch for a motorcycle is disposed in a switch case attached in the vicinity of a grip grip on a handlebar, and a vehicle headlamp can be switched between front irradiation (high beam) and lower irradiation (low beam). ing. Such a headlamp is composed of a lower irradiation lamp whose optical axis is directed downward with respect to the traveling direction in order to irradiate downward, and a front irradiation lamp whose optical axis is substantially parallel to the traveling direction in order to irradiate forward It is configured to irradiate downward when the lower illumination lamp is lit, and to irradiate the front when the front illumination lamp is lit.

  By the way, the dimmer switch usually has a seesaw-type switch knob that can swing in the front-rear direction. If the driver sets the dimmer switch knob to the rear side (downward irradiation position), the vehicle is mounted. When the predetermined circuit in the switching circuit is turned on, the lower irradiation lamp is turned on to enter the lower irradiation state, and if it is set to the front side position (front irradiation position), the other circuits in the switching circuit are turned on and the front irradiation is performed. Switching operation was made possible so that the lamp could be turned on and forward illumination could be used.

  However, as a conventional dimmer switch, a dimmer switch that is configured to be able to temporarily turn on and pass the front irradiation lamp by further swinging the dimmer switch knob at the lower irradiation position to the rear side has been proposed. (For example, refer to Patent Document 1). That is, when the dimmer switch knob is swung forward from the lower irradiation position, the front irradiation position is set, and when the dimmer switch knob is swung backward from the lower irradiation position, the passing position is set.

  According to such a dimmer switch, when the finger is released during a passing operation, the dimmer switch knob automatically swings and restores to the original position (that is, the lower irradiation position). In order to achieve this, a torsion coil spring (restoring spring) is provided. When the dimmer switch knob is swung to the passing position, one end of the torsion coil spring is brought into contact with the dimmer switch knob, and a biasing force is applied in the downward irradiation position direction. Automatic restoration of time was possible.

  However, in the conventional dimmer switch, when the dimmer switch knob is swung forward from the lower irradiation position, it is set to be the front irradiation position, and is swung rearward from the lower irradiation position. When the dimmer switch knob is operated from the front irradiation position to the lower irradiation position, the dimmer switch knob is moved to the passing position depending on the momentum of operation. There was a risk of operation.

  For example, when an oncoming vehicle approaches while driving, if the dimmer switch knob is operated from the front irradiation position to the lower irradiation position in order to switch from front irradiation to lower irradiation, the passing position is inadvertently caused by the momentum of the operation. There is a risk that the operation may be performed unintentionally and the passing operation may be performed unintentionally. That is, in the conventional dimmer switch, when the dimmer switch knob swings backward, the front irradiation position, the lower irradiation position, and the passing position are set in this order, so that the driver can perform the irradiation from the front irradiation to the lower irradiation. In spite of the attempt to switch to, there is a risk of temporary forward irradiation (passing).

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a dimmer switch that can suppress an unintentional passing operation when switching from front irradiation to lower irradiation.

The invention according to claim 1 is disposed in a switch case provided in the vehicle, and a front irradiation position for lighting a front irradiation lamp capable of front irradiation, a lower irradiation position for lighting a lower irradiation lamp capable of lower irradiation, and temporary A dimmer switch knob that can be operated between passing positions for turning on the front illumination lamp and a predetermined circuit according to the position of the dimmer switch knob are formed to switch between the front illumination lamp or the lower illumination lamp. A dimmer switch comprising: a switching means, wherein when the dimmer switch knob is operated from the lower irradiation position to the passing position, the dimmer switch knob is automatically restored by urging the dimmer switch knob toward the lower irradiation position. The dimmer switch knob has a lower irradiation position at one moving end and a front irradiation position at the other moving end. Are, the said passing position between the lower irradiation position and front irradiation position is set, and a moving body that moves along with the dimmer switch knob, and slidable sliding portion movable body, the movable body And a biasing member for biasing the sliding part toward the sliding part, the sliding part having a first position for holding the moving body when the dimmer switch knob is in a lower irradiation position, and the dimmer switch. A second position for holding the movable body is formed when the knob is in the front irradiation position, and the height increases from the first position toward the second position between the first position and the second position. And the boundary between the inclined surface and the second position is set to have a larger inclination angle than the other inclined surfaces, and the dimmer switch knob is predetermined for the operation toward the front irradiation position side. of Characterized in that it is configured to provide a load.

  According to a second aspect of the present invention, in the dimmer switch according to the first aspect, the switching means includes a movable contact that can be moved along with the operation of the dimmer switch knob and a fixed contact that can be brought into contact with or separated from the movable contact. The fixed contact includes a single first fixed contact corresponding to the front irradiation position and the passing position, and a single second fixed contact corresponding to the lower irradiation position.

  The invention according to claim 3 is the dimmer switch according to claim 1 or 2, characterized in that a simultaneous lighting region for simultaneously lighting the front irradiation lamp and the lower irradiation lamp is set in the middle of the passing position. To do.

According to the first aspect of the present invention, the dimmer switch knob has a lower irradiation position at one moving end and a front irradiation position at the other moving end, and is between the lower irradiation position and the front irradiation position. Since the passing position is set, the unintentional passing operation can be suppressed when switching from the front irradiation to the lower irradiation.
Furthermore, an inclined surface that increases from the first position toward the second position is formed between the first position and the second position, and a boundary portion between the first position and the second position is different from that of the second position. The tilt angle is set to be larger than the tilted surface, and it is configured to give a predetermined load to the operation of the dimmer switch knob toward the front irradiation position. It can be suppressed.

  According to the second aspect of the present invention, the switching means has a movable contact that can be moved along with the operation of the dimmer switch knob and a fixed contact that can be brought into contact with or separated from the movable contact. Since it has a single first fixed contact corresponding to the position and a single second fixed contact corresponding to the lower irradiation position, it has fixed contacts corresponding to the front irradiation position and the passing position, respectively. In comparison, the number of contacts can be reduced, and the number of parts can be reduced.

  According to the invention of claim 3, since the simultaneous lighting region for simultaneously lighting the front irradiation lamp and the lower irradiation lamp is set in the middle of the passing position, the dimmer switch knob remains in the simultaneous lighting region for a long time. Can be prevented. In other words, since the dimmer switch knob at the passing position is urged toward the lower irradiation position, the dimmer switch knob is kept stationary for a long time in the simultaneous lighting area in the middle of the passing position. It can be done.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The dimmer switch according to the present embodiment is for switching between a front illumination lamp and a lower illumination lamp that are headlamps provided in the vehicle, and as shown in FIGS. It is mainly composed of switching means D and is disposed in a switch case 1 attached in the vicinity of the grip grip G in the left handlebar H of the two-wheeled vehicle.

  The switch case 1 is composed of two front and rear half-cracked parts. These half-cracked parts are fitted to the left handlebar H while being matched, and then tightened and fixed with bolts or the like, as shown in FIG. It has been. As shown in the figure, the switch case 1 is provided with a dimmer switch 2 according to the present invention, a turn signal switch 3 for blinking the blinker, a horn switch 4 for operating the horn, and the like. It is installed.

  The dimmer switch knob 5 that constitutes the operation part of the dimmer switch 2 is made of a resin molded product that is assembled to a case f as shown in FIG. The front irradiation position (HI) for turning on the lamp (see FIG. 6), the lower irradiation position (LO) for turning on the lower irradiation lamp that can be irradiated downward (see FIG. 4), and the passing position for temporarily turning on the front irradiation lamp (PASS) (see FIG. 5) can be swung. The dimmer switch knob 5 is formed with a through hole 5a penetrating the front and back surfaces, and an axis L that is a central axis of oscillation is inserted into the through hole 5a.

  The front illumination lamp and the lower illumination lamp (both not shown) constitute a headlamp disposed in the front part of the two-wheeled vehicle (vehicle). Among these, the front illumination lamp has an optical axis for irradiating forward. In addition to being directed substantially parallel to the traveling direction, the lower illumination lamp has its optical axis directed downward relative to the traveling direction to irradiate downward. However, when the dimmer switch knob 5 is set to the front irradiation position (HI) and the passing position (PASS), the front irradiation lamp is turned on. On the other hand, when the dimmer switch knob 5 is set to the lower irradiation position (LO), the lower irradiation lamp is turned on. It is supposed to be.

  The switching means D forms a predetermined circuit in accordance with the position of the dimmer switch knob 5, and switches on and off the front irradiation lamp or the lower irradiation lamp. As shown in FIGS. Movable contacts 9a, 9b, and 9c that can move together with the operation of the switch knob 5, and fixed contacts (first fixed contact 6 and second fixed contact 7) that can contact or separate from the movable contacts 9a, 9b, and 9c. Is. The movable contacts 9a, 9b, and 9c are formed on the dimmer switch knob 5 side and are operable with the dimmer switch knob 5. The fixed contacts (the first fixed contact 6 and the second fixed contact 7) It is formed on the surface facing the movable contacts 9a and 9b on the f side.

  Specifically, the movable contacts 9 a, 9 b, 9 c are formed of convex portions formed on a metal contact 9 fixed to the side surface of the dimmer switch knob 5. On the other hand, in the vicinity of the first fixed contact 6 and the second fixed contact 7 on the case f side, it is in a state of being in contact with the contact 9c and electrically connected to a battery (power source) mounted on the two-wheeled vehicle (vehicle). A third fixed contact 8 is formed. 4 to 6, the movable contact 9c maintains contact with the third fixed contact 8 even if the dimmer switch knob 5 is swung between the lower irradiation position, the passing position, and the front irradiation position. It has come to be.

  When the dimmer switch knob 5 is in the downward irradiation position, as shown in FIG. 4, the movable contact 9a is brought into contact with the second fixed contact 7, and the third fixed contact 8 and the second fixed contact 7 are brought into contact with each other. The lower illumination lamp is turned on by conducting and forming a predetermined circuit. When the dimmer switch knob 5 is in the forward irradiation position, as shown in FIG. 6, the movable contact 9b is brought into contact with the first fixed contact 6, and the third fixed contact 8 and the first fixed contact 6 are brought into contact with each other. The front irradiation lamp is turned on by conducting and forming a predetermined circuit.

  Here, the dimmer switch knob 5 according to the present embodiment is at the lower irradiation position at one moving end (forward swing end: see FIG. 4) and the other moving end (backward swing). End: refer to FIG. 6), and the passing position is set between the lower irradiation position and the front irradiation position (see FIG. 5). Thus, when the dimmer switch knob 5 located at the lower irradiation position is swung forward, the lighting position is switched from the lower irradiation lamp to the front irradiation lamp.

  Further, when the dimmer switch knob 5 is operated from the lower irradiation position to the passing position, the dimmer switch knob 5 is biased toward the lower irradiation position and can be automatically restored. That is, the dimmer switch knob 5 is always urged toward the lower irradiation position by a spring 12 to be described later, and when the operating force operated to the passing position is loosened, the dimmer switch knob 5 is automatically restored to the lower irradiation position and restored. It has been done. When the dimmer switch knob 5 is further swung forward from the passing position to reach the front irradiation position, the dimmer switch knob 5 is held at the front irradiation position, and the front irradiation lamp is kept on. It becomes.

  On the other hand, as shown in FIGS. 7 to 9, the dimmer switch knob 5 is formed with a mounting hole 5b that opens downward, and a moving body 10 and a spring 12 as a biasing member are disposed in the mounting hole 5b. In addition, a sliding portion 11 that can slide the moving body 10 is formed on the case f side. The moving body 10 is composed of a metal ball that moves together with the dimmer switch knob 5, and is assembled by being biased toward the sliding portion 11 by a spring 12.

  As shown in FIG. 10, the sliding portion 11 according to the present embodiment includes a first position 11 a that holds the moving body 10 when the dimmer switch knob 5 is in the lower irradiation position (LO), and the dimmer switch knob 5 is forward. A second position 11b for holding the moving body 10 when it is at the irradiation position (HI) is formed, and between the first position 11a and the second position 11b, the first position 11a to the second position 11b are formed. An inclined surface 11c that increases toward the surface is formed, and the boundary portion 11ca between the inclined surface 11c and the second position 11b is set to have a larger inclination angle than the other inclined surfaces 11c.

  That is, when the dimmer switch knob 5 is in the downward irradiation position, the moving body 10 is fitted and held in the concave first position 11a, and the dimmer switch knob 5 is swung to the passing position (PASS). The moving body 10 slides along the inclined surface 11c. At this time, since the moving body 10 is pressed to the inclined surface 11c side by the urging force of the spring 12, the dimmer switch knob 5 is urged toward the lower irradiation side, and automatic restoration is possible. .

  When the dimmer switch knob 5 is further swung forward, the moving body 10 reaches the boundary portion 11ca, and a predetermined load is applied to the swing operation toward the front irradiation position from there. . When the dimmer switch knob 5 is swung against such a predetermined load, the movable body 10 passes over the top α of the inclined surface 11c and is held in the concave second position 11b, so that the dimmer switch knob 5 is held. It will be held at the front irradiation position. However, when the dimmer switch knob 5 is in the passing position, the moving body 10 slides between the first position 11a and the apex α of the inclined surface 11c.

  Here, in the present embodiment, as shown in FIG. 10, in order to prevent the two illumination lamps from being turned off simultaneously when switching from the lower illumination lamp to the front illumination lamp or from the front illumination lamp to the lower illumination lamp. In addition, a simultaneous lighting region β is set in which the front irradiation lamp and the lower irradiation lamp are simultaneously turned on in the middle of the passing position (that is, in a state where the moving body 10 is on the inclined surface 11c). That is, the conduction region A when the dimmer switch knob 5 is at the lower irradiation position (the movable contact 9a is in contact with the second fixed contact 7) and the conduction region B when the dimmer switch knob 5 is at the passing position (the movable contact 9b is the first). The state of contact with the fixed contact 6) is overlapped, and the simultaneous lighting region β is set. In the conduction region C when the dimmer switch knob 5 is in the front irradiation position, the state where the movable contact 9b is in contact with the first fixed contact 6 is maintained as in the conduction region B.

  According to the above embodiment, the dimmer switch knob 5 is at the lower irradiation position (LO) at one moving end (backward swing end) and at the other moving end (front swing end). Since the forward irradiation position (HI) is set to the forward irradiation position (HI) and the passing position (PASS) is set between the lower irradiation position (LO) and the front irradiation position (HI), it is not intended when switching from the front irradiation to the lower irradiation. It is possible to suppress the passing operation.

  That is, when the front irradiation position and the passing position are set across the lower irradiation position as in the conventional dimmer switch, when switching from the front irradiation to the lower irradiation, the position is changed to the lower irradiation, but the passing position is changed depending on the momentum of the operation. If the operation is performed, the lower irradiation position reaches the front irradiation position again, and unintended passing is performed. On the other hand, according to this embodiment, the front irradiation position and the lower irradiation are sandwiched between the passing positions. Since the position is set, it is possible to avoid the forward irradiation again due to the momentum of the operation after switching to the downward irradiation once.

  The switching means D has movable contacts 9a to 9c that can be moved with the operation of the dimmer switch knob 5 and fixed contacts that can be contacted with or separated from the movable contacts 9a to 9c. Since the single first fixed contact 6 corresponding to the passing position and the single second fixed contact 7 corresponding to the lower irradiation position are provided, the fixed contacts corresponding to the front irradiation position and the passing position are provided respectively. The number of contacts can be reduced and the number of parts can be reduced as compared with the above.

  Furthermore, by reducing the number of fixed contacts, the number of wires extending from there to the vehicle can also be reduced. In particular, according to this embodiment, it is sufficient to extend the wiring from the first fixed contact 6, the second fixed contact 7, and the third fixed contact 8, respectively, so that the dimmer switch 2 does not have a passing operation function. (In this case, a total of three wires for front irradiation, lower irradiation, and connection to the power source are required).

  Furthermore, since the simultaneous lighting area β for simultaneously lighting the front irradiation lamp and the lower irradiation lamp is set in the middle of the passing position, the dimmer switch knob 5 is prevented from remaining in the simultaneous lighting area for a long time. be able to. That is, since the dimmer switch knob 5 in the passing position is urged toward the lower irradiation position, the dimmer switch knob 5 stops and stays for a long time in the simultaneous lighting region β in the middle of the passing position. This can be suppressed.

  In addition, an inclined surface 11c that increases from the first position 11a toward the second position 11b is formed between the first position 11a and the second position 11b, and the second position 11b on the inclined surface 11c. Since the inclination angle of the boundary portion 11ca is set larger than that of the other inclined surface 11c, a moderation can be provided between the passing position and the front irradiation position, and the dimmer is unintentionally moved to the front irradiation position at the time of the passing operation. It is possible to suppress the switch knob 5 from being operated.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, as shown in FIGS. 11 and 12, the dimmer switch knob 5 ′ that can slide along the surface of the switch case 1 is used. A dimmer switch 2 ′ having Even in this case, the dimmer switch knob 5 ′ is at the lower irradiation position at one moving end (sliding end) and at the front irradiation position at the other moving end (sliding end). A passing position is set between the lower irradiation position and the front irradiation position, and an unintentional passing operation can be suppressed when switching from the front irradiation to the lower irradiation.

  In addition, when the dimmer switch knobs 5 and 5 ′ are operated from the lower irradiation position to the passing position, a separate spring can be automatically restored by urging the dimmer switch knobs 5 and 5 ′ toward the lower irradiation position. (A coil spring, a torsion spring, etc.) may be provided. Further, in the present embodiment, parts such as the dimmer switch knobs 5 and 5 ′ are assembled with the case f as a casing to constitute the dimmer switches 2 and 2 ′, but the switch case 1 can be assembled with the casing. You may apply to things. In this embodiment, the present invention is applied to a dimmer switch for a two-wheeled vehicle. However, it is arranged in a switch case of another vehicle (for example, ATV) having a front irradiation lamp and a lower irradiation lamp and capable of switching between them. It may be provided.

The dimmer switch knob is at a lower irradiation position at one moving end thereof, and at a front irradiation position at the other moving end, a passing position is set between the lower irradiation position and the front irradiation position , and A moving body that moves together with the dimmer switch knob; a sliding portion that can slide the moving body; and a biasing member that biases the moving body toward the sliding portion. A first position for holding the moving body when the switch knob is in the lower irradiation position and a second position for holding the moving body when the dimmer switch knob is in the front irradiation position are formed, respectively. Between the two positions, an inclined surface that increases from the first position toward the second position is formed, and the boundary between the inclined surface and the second position has a larger inclination angle than the other inclined surfaces. Set If dimmer switch that is configured to provide a predetermined load to the operation to the front irradiation position side of the dimmer switch knob, that external shape is applied to such different or what other functions are added it can.
