Summary:The invention provides a keyboard device and a touch key structure thereof. The keyboard device comprises a circuit substrate, a control unit and a plurality of touch key structures. The control unit is arranged on the circuit substrate. The touch key structures are detachably arranged on the circuit substrate, and each touch key structure comprises a substrate, a key cap, a connecting assembly and a touch sensing circuit layer. The substrate is detachably arranged on the circuit substrate. The key cap is arranged above the substrate. The connecting assembly is arranged between the substrate and the key cap, and the key cap moves up and down relative to the substrate through the connecting assembly. The touch sensing circuit layer is arranged between the substrate and the key cap, the touch sensing circuit layer is electrically connected to the control unit, the touch sensing circuit layer is used for extracting a touch signal, and the control unit receives the touch signal and converts the touch signal into
