The invention provides a touch key board applied to an intelligent door lock, which comprises a PCB (printed circuit board), a plurality of touch keys are arranged on the PCB, and the touch key boardis mainly characterized in that the plurality of touch keys are arranged in an array; wherein each touch key is divided into two sub-parts; in each row, one sub-part of each touch key is connected andcorresponds to one input pin of the MCU; and in each column, the other sub-parts of the touch keys are connected and correspond to one input pin of the MCU. According to the touch control board, outgoing lines of the touch keys can be reduced, so that the number of input pins required by the MCU can be reduced.
本发明提供一种应用于智能门锁的触摸按键板，包括PCB板，PCB板上设有多个触摸按键，其主要改进之处在于：所述多个触摸按键呈阵列排布；每个触摸按键分为两个子部；每一行中，各触摸按键的一个子部相连接，并对应于MCU的一个输入管脚；每一列中，各触摸按键的另一个子部相连接，并对应于MCU的一个输入管脚。本发明可减少触摸按键的引出线，从而可降低MCU所需输入管脚的数量。
