Description

  The present invention relates to a vehicular switch device for turning on or off a predetermined electrical component disposed in a vehicle by operating or operating an operation knob so that a fixed contact and a movable contact come into contact with or move away from each other.

  A switch device for a vehicle attached to a handle pipe in a motorcycle or the like usually has a plurality of switches, and is configured to be able to turn on or off any electrical component provided in the vehicle by operating an operation knob. Yes. Some of the operation knobs of such a vehicle switch device are arranged in a switch case attached to a handle pipe and perform switching by sliding on the surface of the switch case.

  Specifically, the conventional vehicle switch device includes a roller portion that is interlocked with an operation knob in the switch case and provided with a movable contact, and a contact that has a fixed contact while facing the side surface of the roller portion. A plate is disposed, and when the roller portion moves in accordance with the operation of the operation knob, the movable contact contacts or separates from the fixed contact, and electrical switching is performed.

  In addition, an action ball urged by a coil spring is disposed on the roller portion, and the contact plate side is in contact with the action ball and receives an urging force to give a moderation to the operation knob. Mountains are formed. As a result, the action ball is constantly urged in the direction from the roller portion toward the contact plate (substantially perpendicular to the sliding direction of the operation knob). A certain moderation can be obtained by overcoming. In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

  However, in the above conventional switch device for a vehicle, since the action ball is urged in the direction from the roller portion toward the contact plate, there is a problem that the sliding resistance of the roller portion with respect to the contact plate increases. . In order to avoid such excessive sliding resistance, a large action mountain cannot be formed, and there is a restriction on the allowance of the action ball with respect to the roller part, so that the operation knob is automatically restored. There was a problem that could not.

  That is, when the operation knob is slid from the first position to the second position, the slope that receives the urging force of the action ball is used to adopt the automatic restoration structure that automatically restores the first position. Although the shape needs to be provided on the contact plate side, a large slope shape could not be formed for the above reason, and sufficient urging force for automatic restoration could not be secured. Therefore, the conventional sliding switch of the vehicle switch device cannot be applied to a switch that requires automatic restoration, and there is a problem that the application range is narrowed.

  The present invention has been made in view of such circumstances, and provides a vehicle switch device that can obtain a sufficient urging force for automatic restoration of an operation knob and can broaden the application range of a switch. There is.

According to the first aspect of the present invention, a switch case attached to a handle pipe of a vehicle, an operation knob that slides on the surface of the switch case, and the operation knob are connected to be movable in the switch case. A roller plate and a fixed contact that is disposed opposite to the side surface of the roller unit and that is fixed to the switch case, and is formed on the roller unit, and is fixed by movement of the roller unit. A movable contact that can contact with or be separated from the contact; and an action ball that can apply an urging force to the roller portion; and the fixed contact and the movable contact are contacted or separated by operating the operation knob. in the above vehicle switch device for turning on or off a predetermined electrical components arranged in a vehicle, the operation knob is concentric of the handle pipe as the locus by switch Is intended to slide on case surface of the arc-shaped, and the biasing force of the action balls, while being a substantially radial direction of the handle pipe, by the urging force of the action balls, the operation knob When the roller portion is formed with a slope shape that automatically restores to the first position when sliding from the first position to the second position, the fixing plate fixed in the switch case and the A case formed on a fixed plate is provided, and the action ball is accommodated in the case .

  According to the first aspect of the present invention, since the direction of the urging force of the action ball is different from the direction in which the sliding resistance of the roller portion with respect to the contact plate is generated, the slope shape can be formed large, and the operation knob can be automatically restored. Sufficient urging force can be obtained. Therefore, the application range of the switch included in the vehicle switch device can be widened.

Furthermore, when the operation knob slides on the arc surface of the switch case, the slope shape is formed on the roller side and the action ball is formed on the switch case side, so that a larger slope shape is formed. Therefore, the urging force for automatic restoration of the operation knob can be set larger.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The vehicle switch device according to the present embodiment is fixed to a handle pipe of a two-wheeled vehicle, and a predetermined electrical component disposed in the vehicle is turned on by operating or operating an operation knob so that a fixed contact and a movable contact come in contact with or away from each other. 1 or 4, the switch case 1, the operation knob 2, the roller portion 3, the contact plate 4, and the action ball 5 are mainly configured. .

  The switch case 1 is attached to the handle pipe HP of the motorcycle, and on the surface 1a (driver side), in addition to the operation knob 2, other operation knobs 6 to 8 are disposed. An arbitrary switch can be turned on or off by operating any of the knobs. 1 denotes a throttle grip that can be gripped by the driver to open and close the throttle.

  As shown in FIG. 2, the surface 1a of the switch case 1 on which the operation knobs 2, 6 and 7 are disposed has an arc shape that follows the outer peripheral surface of the handle pipe HP. Along with this, the operation knob 2 whose side shape is Mt. Fuji type is configured to be slidable in the direction indicated by the arrow a in FIG. The operation knob 2 is for turning on or off the auto-cruise function, for example. The operation knob 2 is automatically operated at the first position (intermediate position) at which the auto-cruise function is turned on or other factors (when the brake is operated, etc.). When the cruise is canceled, the second position for turning on the auto-cruise function again (position above the intermediate position) and the third position for turning off the auto-cruise function (position below the intermediate position) It is made slidable between.

  The roller portion 3 is connected to the operation knob 2 and can be moved in the switch case 1. As shown in FIG. 3, a movable contact 3 a is formed on the side surface of the roller portion 3. Further, a contact plate 4 fixed in the switch case 1 is disposed at a position facing the side of the roller portion 3, and a predetermined position facing the roller portion 3 on the contact plate 4 is As shown in FIG. 4, a fixed contact 4a is formed. Thus, when the roller portion 3 moves in accordance with the operation of the operation knob 2, the movable contact 3a comes into contact with or separates from the fixed contact 4a of the contact plate 4, and predetermined electrical components (for example, as described above) are arranged. The electrical component that controls the auto-cruise function) can be turned on or off.

  Further, an action mountain 3b and a slope shape 3c are formed at a position facing the handle pipe HP side of the roller portion 3, and an action ball 5 biased by a spring 9 is formed on the action mountain 3b and the slope shape 3c. Are in contact with each other. As shown in FIG. 5, the action ball 5 and the spring 9 are accommodated in a resin case 11 in a fixed plate 10 fixed in the switch case 1, and always apply a biasing force to the roller portion 3. It is configured to

  As shown in FIG. 6, when the operation knob 2 is in the off position (third position), the action ball 5 is at the position A (upper part of the figure from the action mountain 3b), and the resting state is When the operation knob 2 is slid to the ON position (first position) from there, the action ball 5 crosses the action mountain 3b and reaches the position B, so that moderation is given. . Even in the position B, the operation knob 2 remains stationary.

  However, when the operation knob 2 is slid from the first position to the second position, the action ball 5 goes up the slope shape 3c and reaches the position C. Thus, the first position is restored. That is, when the driver picks up the operation knob 2 and slides the operation knob 2 from the first position to the second position, when the driver releases the operation knob 2, the driver spontaneously (automatically) returns to the first position. It is like that.

  Thus, since the urging force of the action ball 5 is the radial direction of the handle pipe HP (the direction indicated by b in FIG. 3), it differs from the direction in which the sliding resistance of the roller part 3 with respect to the contact plate 4 occurs. The slope shape 3c can be formed large. Therefore, sufficient urging force for automatic restoration of the operation knob 2 can be obtained, and the application range of the switch can be widened. That is, if the slope shape is formed on the contact plate side as in the prior art and the urging force of the action ball is applied in that direction (the axial direction of the handle pipe HP), the sliding resistance increases as the slope shape increases. Thus, it is difficult to employ the automatic restoration mechanism, but according to the present embodiment, a sufficient urging force for the automatic restoration mechanism can be applied.

  Furthermore, in the present embodiment, the operation knob 2 is applied to the switch case 1 that slides on the arc-shaped surface 1a, the slope shape 3c is the roller portion 3 side, and the action ball 5 is the switch. Since it is formed on the case 1 side, a larger slope shape 3c can be formed, and the urging force for automatic restoration of the operation knob 2 can be set larger.

  That is, as shown in FIG. 7, since the operation knob 2 is configured to slide between the first position P1, the second position P2, and the third position P3, a position close to the operation knob 2 ( For example, the slope shape 3c can be made larger at a position closer to the handle pipe HP side (for example, a position indicated by L2) than at a position indicated by L1, for example, so that the biasing force for automatic restoration can be increased by the configuration of this embodiment. It can be set large.

As a reference example, for example, as shown in FIG. 8 and FIG. 9, it has an action mountain 1 b and a slope shape 1 c formed on the switch case 1 side, and an action ball 5 and a spring 9 are formed on the roller portion 3 side. The configuration is as follows . According to this configuration, when the roller portion 3 slides as the operation knob 2 is operated, the action ball 5 is urged by the spring 9 and the action mountain 1b and the slope shape 1c formed on the back side of the switch case 1 are urged. Slide. As a result, similar to the previous embodiment, moderation during operation of the operation knob 2 is provided, and automatic restoration with a larger biasing force is enabled by the slope shape 1c.

Although the present embodiment has been described above, the present invention is not limited to this, and the operation knob switches on or off the auto-cruise function, as well as other electrical components that require an automatic restoration function. May be turned on or off. Further, in order to perform the automatic restoration function more reliably, an urging means (spring or the like) that urges the roller portion from the second position to the first position may be provided. For example, when a coil spring is disposed on the contact plate and the operation knob is slid from the first position to the second position, the urging force of the coil spring is applied to the roller portion to assist automatic restoration. It is preferable to do so.

  The action ball 5 according to the present embodiment can be applied with a biasing force by a spring accommodated in the case 11, but it applies a biasing force to the action mountain or the slope shape by other biasing means. It is good. In the present embodiment, the vehicle switch device is provided in a two-wheeled vehicle. However, the present invention may be applied to a switch that requires an automatic restoration in another vehicle having a handle pipe.

When the urging force of the action ball is set to be approximately the radial direction of the handle pipe and the urging force of the action ball is received and the operation knob is slid from the first position to the second position, the first is automatically set. A vehicle is formed by forming a slope shape to be restored to the position of the roller on the roller portion, a fixed plate fixed in the switch case, and a case formed on the fixed plate, in which the action ball is accommodated in the case If it is a switch apparatus for a vehicle, it can apply also to the thing from which the external shape differs, or the thing to which the other function was added.
