The present invention relates to an automobile fuse box and an automobile. The automobile fuse box comprises a common relay, a controller and a plurality of isolation devices, the enable pin of the common relay is connected with a plurality of control signal ends, one of an input end of the common relay and the normally open contact of the common relay is connected with the controller, and the other one of the input end of the common relay and the normally open contact of the common relay is connected with a positive electrode of a power supply; the control pin of the controller is connected with a control signal end, the first output pin of the controller is connected with a first load, and the second output pin of the controller is connected with a second load; and the controller is usedfor outputting the power supply voltage to the first load or the second load according to the control signal sent by the control signal end. Electric appliances with different functions can share onerelay, the problem that too many electric appliances cannot be arranged in an engine room or a cab due to too many relays of the whole vehicle and too large automobile fuse boxes is solved, and the purposes of greatly reducing the number of the relays, reducing the weight of the fuse boxes and reducing the cost are achieved.
本发明涉及一种汽车保险盒及汽车,该汽车保险盒包括:共用继电器、控制器和多个隔离装置,共用继电器的使能管脚连接多个控制信号端,共用继电器的输入端和共用继电器的常开触点的其中一个连接控制器,另一个连接电源正极;控制器的控制管脚分别连接一个控制信号端,控制器的第一输出管脚连接第一负载,第二输出管脚连接第二负载;控制器用于根据控制信号端发送的控制信号,输出供电电压至第一负载或第二负载。本发明通过使不同功能的用电器可共用一个继电器,解决了整车继电器过多、汽车保险盒过大导致的机舱或驾驶室空间不足以布置太多用电器的问题,实现了大幅度减少继电器数量,减少保险盒重量以及降低成本的目的。
