Abstract

The invention provides a touch control device. The touch control device comprises a control button and a touch panel. The control button comprises an insulating main body and a conductive part arranged on the insulating main body. The touch panel is arranged on one side of the control button and comprises a cover plate and a touch element. The conductive part is located between the insulating bodyand the cover plate. The cover plate is located between the control button and the touch element. The touch element is electrically insulated from the conductive part. The touch element comprises a plurality of electrodes corresponding to the control buttons. The conductive part actuates along with the actuation of the insulating body, and the actuation of the conductive part causes at least oneof the plurality of electrodes to generate a capacitance change. The temperature of the control button in the touch control device is not easily influenced by the environment temperature, and a user can operate the control button when wearing gloves.

Description

technical field [0001] The invention relates to an electronic device, in particular to a touch device. Background technique [0002] Existing electronic devices are equipped with touch panels to provide more intuitive and convenient touch operation functions. Some touch devices are also equipped with control buttons (such as knobs), so that users can have a physical sense of touch when operating (such as pressing or rotating). Existing control buttons are mainly made of conductive materials (such as metal). The touch detection is performed by the capacitance change caused by the user touching the control button during operation. Under this structure, the user must operate (eg press or rotate) the control knob with bare hands. In other words, if the user wears gloves (such as non-conductive gloves such as wool or plastic), the control buttons cannot be operated. In addition, since the metal material is easy to conduct heat, the temperature of the control button made of th...
