New energy vehicle charger with good safety

Abstract

The invention discloses a new energy vehicle charger with good safety, comprising a pile base and a plug connected with an electric vehicle; the top end of the pile base is integrally provided with aprotruding portion, a first slide channel extended side to side is arranged in the pile base, a gear groove is arranged in the left end of the first slide channel in the pile base, a worm wheel grooveextended up into the protruding portion is also arranged in the pile base, a retainer groove transversely running side to side and communicated with the worm wheel groove is arranged in the protruding portion, and a retainer is arranged in the retainer groove in a bilaterally slidable manner. The new energy vehicle charger with good safety is simple in structure, good in power supply safety and reliability, and simple and convenient to operate; electric shock accidents occurred during plugging and unplugging of the plug are effectively decreased, and life safety of people is ensured; it can be avoided that charging of an electric vehicle is suddenly disabled due to personnel's mistake kick, and the service life of a battery in the electric vehicle is effectively extended; the new energy vehicle charger with good safety is energy efficient, environmentally friendly and suitable for popularization and use.

Description

technical field [0001] The invention relates to the field of new energy, in particular to a safe charging device for new energy vehicles. Background technique [0002] With the gradual depletion of oil resources, electric vehicles have been well developed in recent years. Electric vehicles refer to vehicles powered by on-board power supplies and driven by motors. Compared with gasoline vehicles, they are more energy-saving and environmentally friendly, so they are being promoted by countries all over the world. [0003] The use of electric vehicles is inseparable from the charging device for supplementing electric energy, and a charger is used between the charging device and the electric vehicle for charging. The traditional charging method of electric vehicles is to insert the plug end of the charger into the charging slot of the charging device to receive power, and the plug end of the charger is inserted into the electric vehicle to supply power, and the plug end is inse...

Problems solved by technology

The traditional charging method of electric vehicles is to insert the plug end of the charger into the charging slot of the charging device to receive power, and the plug end of the charger is inserted into the electric vehicle to supply power, and the plug end is inserted into the power slot to receive power. When the plug-in slot of the traditional charging device is directly connected to the electric wire and is always in the power state, when the personnel operate improperly, it is easy to cause electric shock accidents when plugging and unplugging the plug. In addition, in order to meet the requirements of the charging device and the electric The charging cable connection between cars, the charging cable connected between the plug end and the gun end usually has a certain length. When charging an electric car, the charging cable is usually scattered around the charging device. When someone accidentally kicks it When hitting the charging line by mistake, it will cause the plug end to come out of the charging slot of the charging device and cause the electric vehicle to be charged suddenly. This will not only cause damage to the charging line, but also cause damage to the battery in the electric vehicle. In addition, some charging devices have a very complicated structure, such as some charging devices that are directly equipped with a gun end and can automatically take up the wire. waste of resources
