  The steering switch device described in Patent Documents 1 and 2 is configured to perform a remote operation on one in-vehicle device. For example, a plurality of in-vehicle devices such as a navigation device and an audio device are used. It is convenient if it can be remotely operated with two steering switch devices.

  However, when it is attempted to remotely control a plurality of in-vehicle devices with a single steering switch device, the number of operation switches increases, resulting in an increase in the layout area of the operation surface. In addition, when a large number of operation switches are arranged side by side, there is a problem that it is difficult to understand which in-vehicle device each switch corresponds to and the operability is not good.

  The present invention has been made in view of the above problems, and it is an object of the present invention to ensure operability and to enable remote control of a plurality of in-vehicle devices without increasing the layout area of the operation surface.

  In order to achieve the above object, the invention described in claim 1 is a steering switch device (1) capable of remotely operating a plurality of in-vehicle devices (2, 3) mounted on a vehicle, wherein the opening (50b) ) And an operation member (40) in which operation switches corresponding to each of the plurality of in-vehicle devices (2, 3) are separately arranged on different operation surfaces. Is characterized in that the operating member (50) is rotatably mounted in the mounting member (40) such that the switching member appears from the opening (50b).

Since the operation member (50) is rotatably mounted in the attachment member (40), the operability is ensured, and a plurality of in-vehicle devices can be remotely operated without increasing the layout area of the operation surface. be able to.

  The invention according to claim 2 is characterized in that different concavo-convex patterns (11, 21) for identifying each operation surface are formed on each operation surface.

  As described above, since different uneven patterns (11, 21) for identifying each operation surface are formed on each of the operation surfaces, the driver can operate only by touching the uneven pattern (11, 21). It is possible to recognize which in-vehicle device the operation surface targeted for operation appears in the opening without visually recognizing the surface.

  The invention according to claim 3 is characterized in that a rotation restricting mechanism for restricting the operating member (40) so that the rotation angle is equal to or smaller than a predetermined angle is provided.

  When the signal corresponding to the operation of the operation switch is output from the operation member via the wiring, it is considered that the rotation of the operation member applies a force to the wiring and the wiring is disconnected. According to this configuration, the rotation restriction mechanism restricts the rotation angle of the operation member (40) to be equal to or smaller than a predetermined angle, so that the wiring can be prevented from being disconnected.

  In the invention according to claim 4, the operation member (40) has an operation knob (43) capable of moving the operation member (40) in the rotation axis direction, and the operation knob (43) is When the operation member (40) moves to one end side in the rotation axis direction and rotates, the operation member (40) also rotates together with the operation knob (43), and the operation knob (43) rotates in the rotation axis direction of the operation member (40). The operation member (40) is provided with a mechanism that cannot rotate when moved to the side.

  According to such a configuration, when the operation knob (43) moves to one end side in the rotation axis direction of the operation member (40) and rotates, the operation member (40) also rotates in conjunction with the operation knob (43). ) Moves to the other end side in the rotation axis direction of the operating member (40), so that the operating member (40) becomes non-rotatable, thereby preventing the operating member from rotating against the intention of the driver. be able to.

Although the configuration described above is shown, for example, the operation member 40 whose operation switch corresponding to each in-vehicle device has a polygonal shape (for example, a triangle, a square, a pentagon,...) When viewed from the side. It may be configured to be arranged separately on each surface of the above, and remote control of three or more in-vehicle devices may be possible.

  In the first and second embodiments, the switch switching mechanism 30 that switches the connection destination of each terminal provided in the operation member 40 is provided, and the connection destination is switched by the rotation regulating mechanism 30. Without providing such a switch switching mechanism 30, for example, the navigation device 2 is always connected between each terminal corresponding to various operation switches for performing operations on the navigation device 2 disposed on the surface of the operation member 40 and the navigation device 2. The audio device 3 may be always wired between each terminal corresponding to various operation switches for performing operations on the audio device 3 arranged on the back surface of the operation member 40 and the audio device 3 by wiring with a cable. Moreover, you may comprise so that the radio signal according to operation of an operation switch may be sent out from the operation member 40 between each vehicle equipment.

  In the first and second embodiments, the operation is controlled by the rotation restricting mechanism formed by forming gears on a part of the inner periphery of the support hole 50a and a part of the outer periphery of the shaft portion 40a of the operation member 40, respectively. Although the rotation angle of the member 40 is regulated to be equal to or less than a predetermined angle, the configuration is not limited to such a configuration, and the protrusion is made so that the rotation angle of the operation member 40 is equal to or less than a predetermined angle. A rotation restriction mechanism may be configured by providing a portion or the like, and the rotation angle of the operation member 40 may be restricted to be equal to or less than a predetermined angle.
