Abstract

The invention discloses a touch control type electronic knob and a wiring structure thereof, the touch control type electronic knob comprises an operation knob and an induction circuit unit, and the induction circuit unit comprises a plurality of capacitance induction circuits; a hollow accommodating part is arranged in the operating knob; each capacitive sensing circuit comprises a rotation sensing part and a signal transmission part which are connected with each other; the signal conduction parts of the capacitive sensing circuits are located in the same conduction plane, the operation button is located on one side of the conduction plane, one end of the hollow containing part is open and faces the conduction plane, and the rotation sensing parts are bent into the hollow containing parttowards the side where the operation button is located and evenly arranged on the periphery of the hollow containing part. According to the invention, the capacitive sensing of the control signal canbe realized without carrying out entity rotation operation on the knob, so that the operation control of the equipment can be realized according to the change of the sensing capacitance, the structural stability of the product is improved, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to the technical field of control knobs, in particular to a touch-sensitive electronic knob and its wiring structure. Background technique [0002] The control knobs of existing automobiles, home appliances and other consumer electronic products are mostly mechanical knobs, which can control the switching of the operating state of the equipment through the rotation of the operating knobs. However, mechanical knobs are generally assembled with multiple parts, and the structure is relatively complicated. The life of the mechanical knob is also limited by the strength and toughness of the rotating shaft and other components, so it is difficult to guarantee the reliability of long-term operation. [0003] The design of the capacitive touch knob can make up for the defect in the service life of the mechanical knob, which realizes the operation control of the device by setting the capacitive sensing line in the touch screen. However, s...
