Abstract

The invention discloses a safety device for a new energy vehicle charging gun. The safety device comprises a body, a charging interface, a connecting plate, a charging contact, a first contact plate,a second contact plate and a U-shaped plate, wherein the charging interface is fixedly arranged on one end of the body; first springs are fixedly disposed inside grooves; the connecting plate is connected to the inner side of a cavity in a sleeved manner; the other end of each first spring is fixedly disposed on a side of the connecting plate; the first contact plate is fixedly disposed on the other side of the connecting plate; the second contact plate is fixedly disposed on the inner side of the charging interface at the other side of the cavity; the connecting plate is connected by the twosprings inside the charging interface; the charging contact is fixedly disposed on one end of the connecting plate, and the contact plate to be connected with a charging power source is fixedly disposed on the other end of the connecting plate. Thus, the new energy vehicle is automatically disconnected after the charging is completed to avoid the influence of electric leakage. The safety device issimple, convenient, safe and practical.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle equipment, in particular to a safety device for a charging gun of a new energy vehicle. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as the power source (or the use of conventional vehicle fuels, the use of new vehicle power units), the integration of advanced technologies in vehicle power control and driving, and the formation of advanced technical principles. Vehicles with new technologies and new structures, from the perspective of the development of new energy vehicles in the world, their power sources mainly include lithium-ion batteries, nickel-metal hydride batteries, fuel cells, lead-acid batteries, and supercapacitors. Most of the supercapacitors are auxiliary power sources. form appears. The main reason is that these battery technologies are not fully mature or have obvious shortcomings. Compared with traditional vehicles,...
