The invention discloses a control circuit of a vehicle-mounted electric appliance, and relates to the field of circuits, the control circuit comprises a starting switch and a control module, and the control module controls on and off of the starting switch through a received control signal so as to realize power supply control of the vehicle-mounted electric appliance. The starting switch is connected in series on a power supply loop between the vehicle-mounted storage battery and the switching power supply of the vehicle-mounted electric appliance, and the switching-off of the starting switch directly disconnects the power supply loop of the switching power supply of the vehicle-mounted electric appliance, so that the connection between the electric appliance and the storage battery is thoroughly cut off, and related potential safety hazards are avoided; the stability and the reliability of the control circuit of the whole vehicle-mounted electric appliance are improved, the situations that the vehicle-mounted electric appliance and a vehicle-mounted storage battery are possibly damaged and the like are avoided, and the safety of the whole vehicle body and the vehicle-mounted electric appliance is further guaranteed. The invention further discloses a vehicle-mounted electric appliance system which has the same beneficial effects as the control circuit of the vehicle-mounted electric appliance.
本发明公开了一种车载用电器的控制电路,涉及电路领域,该控制电路包括启动开关和控制模块,控制模块通过接收到的控制信号来控制启动开关的导通和关断,以实现对车载用电器的供电控制。启动开关串联在车载电瓶和车载用电器的开关电源之间的供电回路上,其关断会将车载用电器的开关电源的供电回路直接断开,彻底的切断了用电器和电瓶之间的连接,避免了相关的安全隐患,提高了整个车载用电器的控制电路的稳定性和可靠性,避免了车载用电器和车载电瓶可能产生的损坏等情况,进一步保证了整个车体和车载用电器的安全性。本发明还公开了一种车载用电器系统,具有与上述车载用电器的控制电路相同的有益效果。
