Proximity sensor switch-controlled meter and lamp switch system

摘要

A proximity sensor switch-controlled meter and lamp switch system installed in a motor vehicle that can be a motorcycle or car is disclosed to include a meter having a micro-controller unit (MCU) and an electronic display device, a lamp switch unit installed in one handlebar (or the motorcycle) or steering wheel (of the car), and proximity sensor switches respectively mounted in the meter and the lamp switch unit for controlling the micro-controller unit (MCU) to control the display mode of an electronic display device of the meter or to switch on/off the headlamp or left/right turn signal light of the motor vehicle when the motorcycle rider or car driver touches the meter or the lamp switch unit with a finger.

1. A proximity sensor switch-controlled meter and lamp switch system installed in a motor vehicle, comprising:
a meter comprising a faceplate, a transparent glass covering said faceplate, a circuit board provided at a bottom side of said faceplate and having a micro-controller unit (MCU), and an electronic display device mounted in said faceplate and electrically connected to said micro-controller unit (MCU); and at least one proximity sensor switch mounted in said faceplate disposed in close proximity to said transparent glass and electrically connected to said micro-controller unit (MCU) of said circuit board, each said proximity sensor switch comprising:
an induction plate mounted coplanar within said faceplate and spaced from said transparent glass;non-deformable conducting means directly fastened to said induction plate and said circuit board with a respective nut and kept in contact with a bottom conductor of said induction plate for outputting a signal to said micro-controller unit (MCU) of said circuit board; anda capacitive proximity sensor electrically connected between said non-deformable conducting means and said micro-controller unit (MCU) to detect a change of electric charge at said induction plate and to output a corresponding signal to said micro-controller unit (MCU); wherein a display mode of said electronic display device is selectively switched by a user touching said transparent glass to actuate said proximity sensor switch, said induction plate being thereby actuated to output a signal through said non-deformable conducting means to said capacitive proximity sensor coupled to said micro-controller unit (MCU).
