The invention provides a touch switch device of an automobile steering wheel, and the device comprises a switch shell internally provided with a circuit board; a support panel assembly which is arranged above the switch shell and comprises a panel, a capacitance film and a support, wherein a plurality of keys are arranged on the panel, and the support is provided with a driving structure which canbe pressed by the keys and abuts against a pressure detection piece; the pressure detection part which is connected with the circuit board and suitable for transmitting detected pressure informationto the circuit board which sends an action signal to a vibration part when the pressure exceeds a preset pressure value; and the vibration part which is connected with the circuit board and is suitable for driving the keys to vibrate after the circuit board sends out the action signal. When a user touches the keys on the panel, the driving structure on the support is driven to abut against the pressure detection part, the pressure detection part transmits the detected pressure information to the circuit board, if the pressure exceeds the preset pressure value, the circuit board sends the action signal to the vibration part, the vibration part drives the keys to vibrate, therefore, real-time vibration feedback is provided for the user, and the touch validity is confirmed.

    本发明提供一种汽车方向盘触摸开关装置,包括:开关外壳,其内设有线路板;支架面板组件,设于开关外壳上方,其包括面板、电容膜和支架,面板上设有多个按键,支架设有可受按键按压、与压力检测件相抵的驱动结构;压力检测件,与线路板相连,适于将检测到的压力信息传递至线路板,线路板在压力超过预设压力值时、向振动件发送动作信号;振动件,与线路板相连,适于在线路板发出动作信号后、驱动按键振动。当用户触摸面板上的按键时,会带动支架上的驱动结构与压力检测件相抵,压力检测件将检测到的压力信息传递至线路板,如压力超过预设压力值时,线路板向振动件发送动作信号,振动件驱动按键振动,从而给用户提供实时振动反馈,确认触摸有效。
