Abstract
One general aspect includes a device control switch for a panel assembly, including: a switch base mounted to the panel assembly; a switch button tiltably mounted to the switch base, the switch button configured to tilt away from a default position relative to a horizontal axis, the switch button including a nib; a flexibend sensor fixed to a portion of the switch base, the flexibend sensor in substantial contact with the nib via spring force; and where slight tilting of the switch button away from the default position will cause the flexibend sensor to deflect and remain in substantial contact with the nib as the nib moves with the switch button relative to the horizontal axis.
Claims9
A panel assembly installed in a vehicle, the panel assembly comprising a plurality of device control switches, at least one device control switch of the plurality of device control switches comprising:
- a switch base mounted to the panel assembly;
- a switch button tiltably mounted to the switch base, the switch button configured to tilt away from a default position relative to a horizontal axis, the switch button having a cavity with a nib joined to a centrally located interior wall of the cavity, the nib being a nonconductive protrusion;
- a vertically oriented flexibend sensor installed within the cavity, the flexibend sensor being a cantilever made from a flexible conductive material, a lower end of the flexibend sensor affixed to an interior side of an outer wall of a receptacle area of the switch base, an upper end of the flexibend sensor being in substantial contact with the nib via spring force from a leaf spring portion of the flexibend sensor, the flexibend sensor being operatively connected to an electronic control unit (ECU);
- and
- wherein slight tilting of the switch button away from the default position will cause the flexibend sensor to deflect and remain in substantial contact with the nib as the nib moves with the switch button relative to the horizontal axis, wherein, when the flexibend is deflected, the flexibend sensor will send a signal to the ECU, and wherein the ECU will decipher the signal and generate a notification to be exhibited on a graphical display located within the vehicle, wherein the notification is configured to be a graphical image representation of the panel assembly that highlights the device control switch having slight tilting of the switch button so as to allow a user to understand which device control switch of the plurality of device control switches is being pressed by the user, and wherein the graphical display is not a component of the panel assembly.
A panel assembly installed in a vehicle, the panel assembly comprising a plurality of device control switches, at least one device control switch of the plurality of device control switches comprising:
- a switch base molded to the panel assembly;
- a switch button tiltably mounted to the switch base, the switch button configured to tilt away from a default position relative to a horizontal axis, the switch button configured to fully tilt along the horizontal axis to an actuation position, the switch button having a cavity with a nib joined to a centrally located interior wall of the cavity, the nib being a nonconductive protrusion;
- a vertically oriented flexibend sensor installed within the cavity, the flexibend sensor being a cantilever made from a flexible conductive material, a lower end of the flexibend sensor affixed to an interior side of an outer wall of a receptacle area of the switch base, an upper end of the flexibend sensor being in substantial contact with the nib via spring force from a leaf spring portion of the flexibend sensor, the flexibend sensor being operatively connected to an electronic control unit (ECU);
- wherein slight tilting of the switch button away from the default position will cause the flexibend sensor to deflect and remain in substantial contact with the nib as the nib moves with the switch button relative to the horizontal axis, wherein, when the flexibend is deflected, the flexibend sensor will send a signal to the ECU, and wherein the ECU will decipher the signal and generate a notification to be exhibited on a graphical display located within the vehicle, wherein the notification is configured to be a graphical image representation of the panel assembly that highlights the device control switch having slight tilting of the switch button so as to allow a user to understand which device control switch of the plurality of device control switches is being pressed by the user, and wherein the graphical display is not a component of the panel assembly;
- and
- wherein, when the switch button is fully tilted to the actuation position, the device control switch will send an actuation signal to a vehicle device, the actuation signal configured to actuate the vehicle device.
