The invention discloses an electric vehicle instrument which comprises a shell, a PCB, an isolation plate and an NFC antenna. The PCB, the isolation plate and the NFC antenna are arranged in the shell. The isolation plate is arranged between the PCB and the NFC antenna, and an opening is formed in the isolation plate; a sensing area is arranged at a preset position of the shell; the NFC antenna is fixedly arranged in the induction area, the induction end of the NFC antenna is attached to the interior of the induction area, and the wiring end of the NFC antenna penetrates through the opening in the isolation plate through a data line to be connected with the NFC matching circuit on the PCB. According to the embodiment of the invention, the NFC antenna is fixedly arranged in the induction area, and the induction end of the NFC antenna is attached to the interior of the induction area, so that the distance between the NFC antenna and an external NFC signal source can be effectively shortened, and the recognition effect of the NFC antenna can be effectively improved.

    本发明公开了一种电动车仪表,包括:外壳,以及设置在外壳内的PCB板、隔离板和NFC天线;隔离板设置在PCB板和NFC天线之间,且隔离板上设置有开口;外壳的预设位置设置有感应区域;NFC天线固定设置在感应区域,且NFC天线的感应端贴合在感应区域内,NFC天线的接线端通过数据线穿过隔离板上的开口与PCB板上的NFC匹配电路连接。本发明实施例将NFC天线固定设置在感应区域内,且NFC天线的感应端贴合在感应区域内,能够有效缩短NFC天线与外部NFC信号源的距离,从而能够有效提高NFC天线的识别效果。
