Embodiment Construction

[0052] As mentioned in the background art, with the development of automobiles, automobile body materials are developing from traditional sheet metal materials to lightweight and high-strength materials such as carbon fibers. However, the resistance value of the carbon fiber material is relatively large, resulting in poor electrical conductivity of the car body, which is not conducive to the current transmission during the grounding process of the car; in addition, the surface of the carbon fiber material is often coated with a resin material, which is not conducive to the formation of studs on the car body by welding and other methods. Connecting the car body and car load equipment, the above reasons all affect the effect of car grounding and reduce car safety performance.

[0053] For this reason, the present invention provides a vehicle body grounding system.

[0054] In the body grounding system, a conductive layer is installed in the body shell for grounding, and at least...

Abstract

The invention provides a car body grounding system, which comprises a conducting layer which is inside the car shell and is partly exposed out of the car body shell; a conductive base which is arranged on the car body shell and is in contact with the conductive layer; an elastic component which is arranged between the conductive base and the car shell and used for fixing the conductive base on the car body shell, wherein the end of the elastic component, away from the conductive base, runs through the car body shell, and a conductive bar is arranged on the other end of the elastic component, on the side, without arranging the conducive base, of the car body shell; an electromagnetic coil which is arranged on the conductive base, one end of the wire of the electromagnetic coil is connected with the positive pole of the car battery, the other end of the wire of the electromagnetic coil is connected with the negative pole of the car load device, the car load device is connected with the conducive base and is connected electrically with the conducive layer, The electromagnetic coil is used for forming a magnetic field that generates adsorption force to the conductive bar after being electrified. The car body grounding system can increase the stability of the car grounding.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle body grounding system. Background technique [0002] Grounding technology is a commonly used technology in automotive design at present, which includes selecting a grounding reference point, connecting the automotive circuit or electrical load equipment to the ground reference point, and providing an equipotential point for the circuit system, so as to provide an equipotential point for the current flow of the circuit or electrical load equipment. Provides a low-impedance path back to ground for automotive circuits or electrical loads. Grounding technology can effectively reduce the interference of sensor signals in the electronic control system of the car, and suppress the electromagnetic interference of the car to improve the performance of the car. [0003] The existing grounding technology is mostly the nearest grounding technology, with the body sheet metal as...
