With the development of automobile industry in China, automobiles are already close to families of people, and the popularization of the automobiles is increased day by day. People often encounter the phenomenon of being powered when getting on or off the vehicle by bus. At present, people can generally adopt a medium which is hung and arranged under a vehicle body to release the static electricity of the vehicle body. Although this method can provide a certain effect, it cannot ensure complete discharge of static electricity from the vehicle body itself, and cannot ensure complete safety. Because the automobile tires are insulated from the ground, static electricity is difficult to release in dry weather, and fire and explosion accidents caused by electric shock sparks due to static electricity of automobile bodies are avoided more and more cautiously in flammable and explosive dangerous areas and antistatic places. In addition, the traditional simple static electricity releasing device can release the static electricity to the ground through the carrier (medium) under the environment that the ground is relatively humid, and the static electricity is difficult to release in the environment that the air is dry. Most importantly, no effective method for in-vehicle static electricity removal exists at present, so that static electricity in the vehicle cannot be released, and user experience is poor.
