It is a horn switch operation knob for sounding.

  According to the first aspect of the present invention, since the communication circuit is provided which can transmit the identification signal corresponding to the operation knob together with the detection signal from the detection means to the multiplex communication means, the wiring extending from the switch case to the vehicle side The number can be suppressed. Further, since the substrate on which the detection means and the communication circuit are formed is disposed in the switch case, the switch case can be reduced in size as compared with the case in which the detection means is disposed in a portion different from the substrate. .

  According to the second aspect of the present invention, since the magnet that operates together with the operation knob is provided, the detection means includes magnetic detection means that can detect a magnetic force from the magnet and generate a detection signal. The operation of the operation knob can be reliably detected, and the operation of the operation knob can be detected accurately over a long period of time.

Further, the switch case can be further reduced in size.

  According to the invention of claim 4, the operation knob is an operation knob of a turn signal switch for causing a turn flasher mounted on the vehicle to blink, and an operation knob of a horn switch for sounding a horn mounted on the vehicle. For example, it can be easily applied to a general-purpose switch case fixed near the left end of the handlebar in a two-wheeled vehicle.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
As shown in FIG. 3, the switch device for a vehicle according to the present embodiment is for operating various electrical components mounted on the two-wheeled vehicle in a switch case 1 fixed near the left end of the handlebar H of the two-wheeled vehicle. A plurality of operation switches (2, 3, 4) are formed. As shown in FIG. 1, the switch case 1 is formed by combining a first switch case 1a and a second switch case 1b each having a half crack shape.

  An arcuate hole 1aa is formed on the mating surface of the first switch case 1a with the second switch case 1b in the switch case 1, and a portion corresponding to the hole 1aa in the second switch case 1b is similarly circular. An arc-shaped hole 1ba is formed. As a result, when the outer peripheral side surface of the handle bar H is fitted in the hole 1aa and the hole 1ba, the first switch case 1a and the second switch case 1b are fitted together, and the both are tightened with bolts or the like. The gripping grip G (see FIG. 3) in the handle bar H is fixed to the base end side.

  As shown in FIG. 1, a dimmer switch 2, a turn signal switch 3 (operation switch), and a horn switch 4 are provided on the surface of the first switch case 1a (that is, the surface facing the driver in the switch case 1). (Operation switch) operation knobs are formed respectively. In particular, the operation knob 5 of the turn signal switch 3 and the operation knob 6 of the horn switch 4 are formed on the lower half side of the switch case 1.

  As shown in FIGS. 4 and 6, the turn signal switch 3 is attached to a case 7 constituting a CAN unit Y, which will be described later, and an operation knob 5 made of resin that allows an operator to hold or abut a finger. The rocking member 5 a extending from the operation knob 5 is mainly configured. The turn signal switch 3 is swingable from the neutral position to the left and right around the swing shaft L1 provided on the case 7, and can be pushed in from the neutral position. The swing member 5a is formed with a long hole 5aa extending in the same longitudinal direction (vertical direction in the figure), and the swing shaft L1 is inserted into the long hole 5aa and assembled.

  Further, as shown in FIG. 6, the end of the swinging member 5a is in contact with a steel ball 9 biased by a coil spring 8 disposed in the case 7, and the operation knob 5 is moved to either the left or right. When the swinging operation is performed, the swinging operation is performed about the swinging shaft L1 while resisting the urging force of the coil spring 8. When the operator removes his / her finger from the operation knob 5, the coil spring 8 is biased to return to the neutral position (initial position). On the other hand, when the operation knob 5 is pushed into the case 7, the long hole 5aa allows movement in the same direction, so that the operation knob 5 is moved upward in FIG. 6 against the urging force of the coil spring 8. Move to. When the operator removes his / her finger from the operation knob 5, the operation knob 5 moves downward in the figure by the urging force of the coil spring 8 and returns to the neutral position.

  Here, the swinging member 5a of the operation knob 5 is formed with plastic magnets (5b, 5c) in place of the conventional movable contact on the left and right, respectively. The plastic magnets 5b and 5c are to be molded by mixing magnetic powder with magnetism into plastic, and are formed to protrude in the left-right direction with respect to the swing member 5a of the operation knob 5. However, when the operation knob 5 is swung or pushed, the pair of plastic magnets 5b and 5c can be moved in the left-right direction or moved in the push-in direction based on the operation.

  As shown in FIGS. 4, 5 and 9, the horn switch 4 is attached to a case 7 constituting a CAN unit Y, which will be described later, and a resin operation knob 6 that allows an operator to abut a finger. And a roller 10 that operates in conjunction with the pushing operation of the operation knob 6. The horn switch 4 is swingable from a neutral position to a pushed-in position with a swing shaft L2 provided on the case 7 as a center.

  The roller 10 is slidably disposed in the case 7 while being in contact with a part 6 a of the operation knob 6, and is urged by a coil spring 13 and the coil spring 13 as shown in FIG. 9. Steel ball 14 is provided. The steel ball 14 is in contact with a receiving member 15 formed on the case 7 side. When the operation knob 6 is pushed in and the roller 10 moves upward in FIG. The ball 14 is pressed, and the urging force by the coil spring 13 is obtained. When the operator removes his / her finger from the operation knob 6, the operator returns to the initial position by the biasing force of the coil spring 13.

  Here, the roller 10 constituting the horn switch 4 is formed with a plastic magnet 10a in place of the conventional movable contact. This plastic magnet 10a is to be molded by mixing magnetic powder with magnetism into plastic like the plastic magnets 5b and 5c in the turn signal switch 3, and is formed so as to protrude in the pushing operation direction of the roller 10. Has been. However, when the operation knob 6 is pushed in, the plastic magnet 10a can be moved in the same direction based on the operation.

  In the present embodiment, inside the switch case 1 (in the present embodiment, the lower half side of the switch case 1), as shown in FIG. Yes. Here, CAN refers to “controller area network” (in-vehicle LAN), and is connected to each electrical component (turn flasher, horn, etc.) mounted on the vehicle to multiplex communication (in one transmission line). A communication form capable of sending a plurality of information (signals).

  As shown in FIGS. 7, 8, and 10, a substrate 11 is disposed in the case 7. As shown in FIG. 10, a microcomputer 19, a power supply circuit 20, a communication circuit 21, and Hall elements 12 a, 12 b, and 16 as magnetic detection means (detection means) are disposed on the substrate 11. The microcomputer 19 is electrically connected to the dimmer switch 2 and the like formed in the switch case 1, and is also electrically connected to the power supply circuit 20, the communication circuit 21, and the hall elements 12a, 12b, and 16.

  The Hall elements 12a, 12b, and 16 have resistance values that change according to the strength of the magnetic force applied from the magnets, and vary the output voltage. In the present embodiment, the Hall elements 12a, 12b are the turn signal switches 3. The positions corresponding to the plastic magnets 5b and 5c (one surface of the substrate 11: see FIG. 7), the Hall element 16 corresponding to the plastic magnet 10a of the horn switch 4 (the other surface of the substrate 11: see FIG. 8) Are formed respectively. Note that reference numeral 18 in FIG. 7 denotes an illumination LED formed on the substrate 11, and the light emitting portion 17 of the CAN unit Y can be caused to emit light by the illumination LED.

  Thus, when the operation knob 5 of the turn signal switch 3 is swung to the right from the initial position (see FIGS. 4 and 7), as shown in FIG. 11, the proximity state between the plastic magnet 5b and the hall element 12a is maintained. In addition, since the plastic magnet 5c and the hall element 12b are separated from each other, the hall element 12a is turned on and the hall element 12b is turned off. With this detection signal, it can be detected that the operation knob 5 has been swung to the right.

  When the operation knob 5 of the turn signal switch 3 is swung to the left from the initial position (see FIGS. 4 and 7), the proximity state between the plastic magnet 5c and the hall element 12b is maintained as shown in FIG. In addition, since the plastic magnet 5b and the hall element 12a are separated from each other, the hall element 12b is turned on and the hall element 12a is turned off. With this detection signal, it can be detected that the operation knob 5 has been swung to the left.

  Further, when the operation knob 5 of the turn signal switch 3 is pushed and swung from the initial position (see FIGS. 4 and 7), as shown in FIG. 13, the plastic magnets 5b and 5c are separated from the hall elements 12a and 12b. Therefore, both the Hall elements 12a and 12b are turned off. From this detection signal, it can be detected that the operation knob 5 has been pushed in (cancelled).

  However, detection signals from the hall elements 12 a and 12 b of the turn signal switch 3 are sent to the communication circuit 21 via the microcomputer 19. In the microcomputer 19, an identification signal (IP address) corresponding to the turn signal switch 3 (operation knob 5) is given to the received detection signal. Thereby, the communication circuit 21 can transmit the identification signal corresponding to the operation knob 5 to the multiplex communication means 22 on the vehicle side together with the detection signals from the hall elements 12a and 12b.

  On the other hand, when the operation knob 6 of the horn switch 4 is pushed from the initial position (see FIGS. 5 and 8) (swing operation with respect to the swinging shaft L2), the roller 10 slides in the same direction as shown in FIG. Since the plastic magnet 10a is close to the Hall element 16, the Hall element 16 is turned on. This detection signal can detect that the operation knob 6 has been pushed.

  However, the detection signal from the Hall element 10 a of the horn switch 4 is sent to the communication circuit 21 via the microcomputer 19. In the microcomputer 19, an identification signal (IP address) corresponding to the horn switch 4 (operation knob 6) is given to the received detection signal. Thereby, the communication circuit 21 can transmit the identification signal corresponding to the operation knob 6 to the multiplex communication means 22 on the vehicle side together with the detection signal from the hall element 10a.

  In the multiplex communication means 22 on the vehicle side, it is grasped which electrical component should be operated or actuated by the identification signal, so that any electrical component mounted on the vehicle via the multiplex communication means 22 (depending on the operation knob) Can be operated. That is, when the operation knob 5 is swung, either the left or right of the turn flashers mounted on the vehicle blinks according to the identification signal and the detection signal, and when the push knob is pushed, the turn flasher blinks according to the identification signal and the detection signal. Is stopped (cancelled), and further, when the operation knob 6 is pushed in, a horn mounted on the vehicle is sounded according to the identification signal and the detection signal.

  Therefore, according to the present embodiment, the identification signal (IP address) corresponding to the operation knob (5, 6) together with the detection signal by the hall element (12a, 12b, 16) can be transmitted to the multiplex communication means 22. Since the circuit 21 is provided, it is not necessary to increase the number of wires according to the number of operation knobs as in the prior art, and the number of wires extending from the switch case 1 to the vehicle side can be suppressed.

  In addition, since the substrate 11 on which the Hall elements (12a, 12b, 16) and the communication circuit 21 as the detection means are formed is disposed in the switch case 1, the detection means is disposed at a site separate from the substrate 11. The switch case 1 can be downsized as compared with the one to be performed. Moreover, in this embodiment, since the board | substrate 11 and the detection means are integrated in the CAN unit Y which used the case 7 as a housing | casing, the assembly workability | operativity with respect to the switch case 1 can be improved.

  Furthermore, the magnets (plastic magnets 5b, 5c, 10a) that operate together with the operation knobs 5, 6 are provided, and the detection means detects the magnetism from the magnets and can generate a detection signal (12a, 12b). 16) (magnetic detection means), the operation of the operation knob can be reliably detected in a non-contact manner, and it can be performed over a long period of time compared with a conventional contact using physical contact. The operation of the operation knobs 5 and 6 can be detected with high accuracy.

  Furthermore, the substrate 11 includes a plurality of Hall elements (detecting means) for detecting the operations of a plurality of operation knobs (in this embodiment, the operation knob 5 of the turn signal switch 3 and the operation knob 6 of the horn switch 4). As a result, the switch case 1 can be further reduced in size as compared with the case where the plurality of detection means are disposed at portions other than the substrate 11. In the present embodiment, the substrate 11 is formed with the hall elements 12a and 12b for detecting the operation of the operation knob 5 and the hall element 16 for detecting the operation of the operation knob 6. Hall elements (including other detection means) for detecting (for example, an operation knob of the dimmer switch 2) may be formed on the same substrate 11.

  Further, the operation knobs are the operation knob 5 of the turn signal switch 3 for causing the turn flasher mounted on the vehicle to blink, and the operation knob 6 of the horn switch 4 for sounding the horn mounted on the vehicle. It can be easily applied to a general-purpose switch case 1 fixed in the vicinity of the left end of the handle bar H. That is, the general-purpose switch case 1 fixed near the left end of the handlebar H in a two-wheeled vehicle has substantially the same position (layout) of the operation knob 5 of the turn signal switch 3 and the operation knob 6 of the horn switch 4. Therefore, application of this embodiment is facilitated.

  According to the above embodiment, since the two hall elements 12a and 12b can perform three operations such as the blinking operation of the left blinker, the blinking operation of the right blinker, and the cancel operation, the operation knob 5 The manufacturing cost of the turn signal switch 3 can be reduced as compared with the one provided with three magnetic detectors for detecting the three operations.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, in place of the Hall element, other magnetic detection means that can detect the magnetism of the magnets (plastic magnets 5b, 5c, 10a). Also good. The detecting means for detecting the operation of the operation knobs 5 and 6 may be other general-purpose ones that detect magnetism as in this embodiment, and transmits a weak current (electric signal) such as a microswitch. It may be a contact type.

  Furthermore, in the CAN unit Y according to the present embodiment, the operation of the operation knob 5 of the turn signal switch 3 and the operation knob 6 of the horn switch 4 can be detected. You may comprise so that operation | movement may be detected and the detection signal and identification signal may be transmitted to the multiplex communication means 22 of the vehicle side via the communication circuit 21. FIG. Of course, the operation of the operation knob of another operation switch may be detected, and the detection signal and the identification signal may be transmitted to the multiplex communication means 22 on the vehicle side via the communication circuit 21.

  In this embodiment, the present invention is applied to a vehicle switch device fixed to a handlebar of a two-wheeled vehicle. However, in a vehicle switch device of another vehicle having a handlebar (for example, a snow vehicle, ATV, buggy, etc.). Can also be applied. Note that the switch device according to the present embodiment is disposed in the vicinity of the left end of the handle bar, but may be applied to a switch disposed in the vicinity of the right end.
