Power supply expansion interface device for automobile

Abstract

The invention discloses a power supply expansion interface device for an automobile. The power supply expansion interface device for the automobile comprises an insulation box body, wherein the insulation box body is mounted in an automobile compartment body; an anode input port, a cathode input port, a cathode output port and at least two anode output ports are arranged in the insulation box body; the cathode input port is connected with the cathode output port; the anode input port is connected with the anode output ports in a branched way; the anode input port is connected with a positive terminal of an automobile storage battery; and the cathode input port is connected with a negative terminal of the automobile storage battery. As a plurality of power supply interfaces are placed in the compartment in advance, a problem of the existing automobile that the power supply cannot be connected when a user needs to mount additional electric control products is solved, convenience is provided for the automobile user to connect the power supply during mounting the additional electric control products, and power supply line hidden troubles caused because the automobile user mounts the additional electric control products in the automobile can be also effectively prevented.

Description

technical field [0001] The invention relates to the field of automobile accessory equipment, and more specifically relates to an automobile power supply expansion interface device. Background technique [0002] At present, car users add some electronic control products to their cars due to personal needs during the use of cars. The electronic control products added by users in the car need to obtain power from the car itself. In order to obtain power, users may obtain power from the power lines of the original automotive electronic components when adding electronic control products. Since the load capacity of the power line of the original car-related electronic components has been determined, the electronic control products added by the user will increase the load on the original power line of the car-related electronic parts, which will cause the power line to be overwhelmed and burn out. This problem will also lead to the instability of the power supply of the original ...

AI Technical Summary

Problems solved by technology

[0006] The invention creatively adopts multiple power supply interfaces in the compartment in advance, which solves the problem of power supply access when the current car users need to add electronic control products. After applying the power expansion interface of the present invention in the car, it is not only convenient for car users to add electronic control products It can also effectively prevent the hidden dangers of power lines caused by the addition of electronic control products by car users in their cars.
