Automobile fuse box and automobile

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of vehicle electronics, in particular to an automobile fuse box and an automobile. Background technique [0002] With the development of technology in the vehicle industry and the strengthening of competition in the vehicle industry, the electrical functions on the vehicle are increasing, especially some electrical equipment related to safety, comfort, intelligence, etc. Complicated, the number of fuses and relays required increases sharply. Whether it is a traditional vehicle or a new energy vehicle, there are various relays, such as light relays, starter relays, oil pump relays, fan relays, air-conditioning relays, etc. Therefore, a large number of relays make the physical inspection of the fuse box larger and larger, resulting in a decrease in the utilization rate of the space in the car, and the cost of the whole car is also higher and higher. [0003] Existing general technical schemes all are a kind ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a car fuse box and a car. By making electrical appliances with different functions share one relay, it solves the problem of too many relays in the whole vehicle and too large car fuse boxes. The problem of multiple electrical appliances has achieved the purpose of greatly reducing the number of relays, reducing the weight of the fuse box and reducing the cost
