The invention relates to a switching device for a vehicle machine, the vehicle machine and a vehicle in the technical field of vehicles, and the switching device for the vehicle machine comprises a power supply connector which is connected with a vehicle power supply; the input interface is connected with a wire harness to be switched in the vehicle machine body; the output interface is connected with corresponding external equipment; and a built-in circuit, which is communicated with the input interface and the output interface to realize signal and/or data transmission, and is communicated with the power supply connector and at least part of the output interface to provide voltage for the correspondingly connected output interface. Therefore, when the vehicle machine is replaced and upgraded, the wiring harness to be switched in the vehicle machine is connected with the corresponding input interface, and the wiring harness of the external equipment is connected with the corresponding output interface, so that the original wiring harness arrangement does not need to be modified, the upgrading difficulty is reduced, and the time cost and the labor cost are also reduced; the vehicle power supply is connected with the corresponding output interface through the power supply connector and the built-in circuit so as to supply power to external equipment needing external power supply, and the requirement for system change is met.
本公开涉及车辆技术领域的车机用转接装置、车机及车辆,该车机用转接装置包括:电源连接器,与车辆电源连接;输入接口,与车机本体中待转接的线束连接;输出接口,与对应的外接设备连接;内设电路,连通输入接口与输出接口,以实现信号和/或数据传输,以及连通电源连接器和至少部分输出接口,以向对应连接的输出接口提供电压。如此,进行更换车机升级时,将车机中待转接的线束与对应的输入接口连接,以及将外接设备的线束与对应的输出接口连接,不需要修改原有线束布置,不仅降低了升级难度,还降低了时间成本和人力成本;车辆电源通过电源连接器和内设电路与对应的输出接口连接,以实现向需要外部供电的外接设备供电,满足了系统变更的需求。
