Abstract

The invention discloses a knob, which comprises a fixing column, a substrate, a first touch sensing assembly, a conductive shell and a controller, wherein the substrate has a central region at the center of the substrate and an edge region disposed around the central region, the first touch sensing assembly is arranged in the edge region of the substrate, a first touch sensing device comprises a plurality of touch electrodes, the touch electrodes are configured to be provided with a plurality of capacitors, the conductive shell sleeves the peripheral side of the fixing column, the conductive shell comprises conduction parts arranged at intervals with the plurality of touch electrodes, and can rotate around a shaft parallel to the axial direction of the fixing column relative to the fixingcolumn so as to selectively couple the conduction part with one of the plurality of capacitors, the first touch sensing assembly is electrically connected with the controller, and the controller can receive touch information generated by coupling of the conduction part and the capacitor. The embodiment of the invention is provided with the touch sensing assembly, so that the touch sensing functionis integrated in the knob by a simple structure.

Description

technical field [0001] The invention relates to the field of rotation sensing devices, in particular to a knob. Background technique [0002] Knobs exist everywhere in our life. For example, on automobiles, fans and other devices, there are knobs for adjusting functions or gear positions. By turning the knobs, quick conversion and adjustment of corresponding functions or gear positions can be realized. [0003] In order to achieve more functional changes through the knob, it is desirable to combine the touch sensing 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 way of combining the touch sensing function with the knob is relatively complicated. Contents of the invention [0004] The invention provides a knob, which integrates a touch sensing function into the knob with a simpler structure. ...
