Safe charging equipment suitable for electric vehicle

Abstract

The invention belongs to the technical field of electric vehicles, and particularly relates to safe charging equipment suitable for an electric vehicle. The safe charging equipment comprises a semicircular plug, a connector, a handle and a limiting fixture block. Two conditions in the background are identified through a speed type damper, the strong practical effect of the locking degree under each condition is determined. When the charging equipment is suddenly impacted, if a person accidentally stumbles on an electric wire of the charging equipment, the charging equipment cannot be separatedfrom the electric vehicle, so that the charging equipment and the electric vehicle can be prevented from being damaged due to sparks caused by a gap formed between mutually nested and matched parts of the charging equipment and the electric vehicle. At the end of the electric vehicle charging, when people drive away the electric vehicle without pulling off the charging equipment, the charging equipment can prevent parts, nested and matched with the electric vehicle, of the charging equipment from being pulled and damaged, particularly when the electric vehicle pulls a charging pile through anelectric wire and damages the charging pile accordingly.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a safe charging device suitable for electric vehicles. Background technique [0002] Electric vehicles refer to vehicles that are powered by vehicle-mounted power supplies and driven by motors to drive wheels, and meet the requirements of road traffic and safety regulations. Because they have less impact on the environment than traditional vehicles, their prospects are widely optimistic. Among them, electric vehicles have special Its charging device makes it possible to ensure sufficient power for use.

[0003] When charging, if someone accidentally trips over the wire of the charging device and gives the charger a momentary impact, there will be two situations in this situation. One is that the wire is pulled, but because the force is small, the wire is weaker. thick, it will not have much impact; the second is that the plug is pulled apart, because the electric current of the general electric vehicle is relatively large, and the loose plug may cause sparks and cause accidents; in view of this situation, it is hoped that the plug is inserted Tighter and not easy to loosen
