Description

  The present invention relates to a vehicular switch device using a capacitive switch attached to an instrument panel or the like.

  2. Description of the Related Art Conventionally, vehicles such as automobiles have been provided with a switch device for operating on-vehicle equipment such as a lighting device, an air conditioner, and an audio device. As this switch device, there is one using a capacitance type switch, and an example thereof is disclosed in Patent Document 1.

  This switch device is attached to a front seat door of an automobile, and has a translucent decorative panel with a decorated surface and a plurality of electrodes formed on the back side of the decorative panel. An electrode sheet, a holder that is disposed on the back side of the electrode sheet and holds the electrode sheet, a circuit board that is disposed on the back side of the holder, and a case that covers the circuit board and the like from the back side. Yes.

  The decorative panel is curved so as to bulge toward the passenger compartment, and the electrode sheet is formed of a flexible sheet so as to follow this curved shape. In addition, while the LED is installed at the electrode corresponding place on the surface of the circuit board, the surface of the holder extends vertically, and guides the light emitted from the LED to the LED corresponding place to the electrode and its peripheral part. A hole is formed.

  When the LED on the circuit board is lit, the pattern formed on the electrode sheet appears on the decorative panel. When an occupant touches a location corresponding to this symbol, the capacitance of the electrode changes, and the detection unit of the circuit board detects this change in capacitance. The detection unit sends a detection signal to the control circuit, and the control circuit controls the in-vehicle device based on the detection signal.

  However, in the vehicle switch device described in Patent Document 1, the electrode sheet follows the curved shape of the decorative panel, and the surface of the holder on the back side of the electrode sheet extends vertically. A gap is formed. Then, the electrode sheet can be moved to the holder side, and there is a possibility that the electrode sheet is separated from the decorative panel. When an electrode sheet leaves | separates from a decorating panel, the electrostatic capacitance variation | change_quantity of the electrode when a passenger | crew touches a decorating panel becomes small, and the contact to a passenger | crew's decorating panel cannot be detected with sufficient sensitivity. Therefore, in order to detect the capacitance change of the electrode with high sensitivity, it is necessary to increase the detection sensitivity of the detection unit. However, increasing the detection sensitivity of the detection unit may erroneously detect not only the capacitance change of the electrode corresponding to the pattern that the occupant is trying to operate, but also the capacitance change of the electrode adjacent to the electrode. There is a problem that an unintended operation is executed.

  Moreover, when an electrode sheet leaves | separates from a decorating panel, there exists a possibility that the pattern which floats on a decorating panel may blur, or the position of an electrode may shift | deviate.
