Abstract

The invention discloses a knob. The knob includes a fixed column, a base plate, a first touch sensing component, a conductive housing and a controller. The substrate has a central area at its center and an edge area disposed around the central area. The first touch sensing component is disposed on the edge area of ​​the substrate, the first touch sensing device includes a plurality of touch electrodes, and the plurality of touch electrodes are configured to have a plurality of capacitors. The conductive shell is sleeved on the outer peripheral side of the fixed column, and the conductive shell includes a conductive portion arranged at intervals from the plurality of touch electrodes. The conductive shell can rotate relative to the fixed column around an axis parallel to the axial direction of the fixed column, so that the conductive portion and the One of the plurality of capacitors is selectively coupled. The first touch sensing component is electrically connected to the controller, and the controller can receive touch information generated by the coupling of the conductive part and the capacitor. The embodiment of the present invention has its own touch sensing component, and integrates the touch sensing function into the knob with a more compact structure.

Description

technical field [0001] The invention relates to the field of rotation induction devices, in particular to a knob. Background technique [0002] Knobs exist everywhere in our life. For example, in automobiles, fans and other devices, they all include knobs for adjusting functions or gears. By rotating the knobs, quick change and adjustment of the corresponding functions or gears can be achieved. [0003] In order to realize the transformation of more functions through the knob, it is expected to combine the touch-sensitive function with the knob. In the prior art, in order to combine the touch sensing function with the knob, the knob needs to be arranged on the touch display panel to utilize the touch sensing function of the touch display panel. The manner in which such a touch sensing function is combined with the knob is complicated. SUMMARY OF THE INVENTION [0004] The present invention provides a knob, which integrates the touch sensing function into the knob with a m...
