충전 케이블 자동 감기 기능을 가진 전기자동차 충전기{ELECTRIC VEHICLE CHARGER WITH FUNCTION TO AUTOMATICALLY WIND THE CHARGING CABLE}Electric vehicle charger with automatic winding function of charging cable {ELECTRIC VEHICLE CHARGER WITH FUNCTION TO AUTOMATICALLY WIND THE CHARGING CABLE}

본 발명은 충전 케이블 자동 감기 기능을 가진 전기자동차 충전기에 관한 것으로서, 보다 상세하게는 전기자동차 충전 후, 충전 케이블이 자동으로 감길 수 있도록 하는 충전 케이블 자동 감기 기능을 가진 전기자동차 충전기에 관한 것이다.The present invention relates to an electric vehicle charger having an automatic winding function of a charging cable, and more particularly, to an electric vehicle charger having an automatic charging function of a charging cable that allows the charging cable to be automatically wound after charging the electric vehicle.

최근 환경에 대한 관심이 많아지고, 실제로 환경오염에 대한 문제가 많이 발생함에 따라, 전기 자동차에 대한 개발이 활발하게 진행되고 있다.Recently, as interest in the environment has increased and many problems with environmental pollution have actually occurred, development of an electric vehicle has been actively conducted.

전기자동차는 전기를 에너지 삼아 전기 모터를 돌리는 자동차를 뜻하는 것으로, 영어로는 Electric Vehicle의 약자인 EV로 통칭된다. 다시 말해, 전기자동차는 자동차의 구동 에너지를 기존의 자동차와 같이 화석 연료의 연소로부터가 아닌 전기에너지로부터 얻는 자동차이다.Electric vehicle refers to a vehicle that uses electric energy to run an electric motor. In English, EV is an abbreviation of Electric Vehicle. In other words, the electric vehicle is a vehicle that obtains the driving energy of the vehicle from electric energy, not from the combustion of fossil fuels like the conventional vehicle.

한편, 현재 출시되어 있는 전기자동차용 충전기의 경우, 5m 이상의 충전 케이블을 거치하기 위한 방안으로, 충전 케이블을 별도의 걸이에 걸어 보관하거나, 혹은 별도의 수납 공간에 넣어 보관하게 된다. On the other hand, in the case of a charger for an electric vehicle that is currently on the market, as a way to mount a charging cable of 5 m or more, the charging cable is stored in a separate hanger or stored in a separate storage space.

하지만, 이때 충전 케이블의 길이가 길어 충전 케이블의 일부는 바닥에 늘어뜨려진 상태가 되고, 충전 케이블이 도로에 방치되어, 자외선에 노출되거나 차량 바퀴에 의해 케이블이 손상되는 경우가 많다. However, at this time, the length of the charging cable is long, so a part of the charging cable is suspended on the floor, and the charging cable is left on the road, and is often exposed to ultraviolet rays or the cable is damaged by vehicle wheels.

특히, 전기자동차 충전기의 고장률은 통상적으로 충전 케이블 고장이 약 80%를 차지하고 있으며, 충전 케이블의 고장의 원인은 상술한 바와 같이, 충전 케이블을 취급하는 과정에서 바닥에 깔려있는 충전 케이블 마모에 의한 외피훼손이나, 자동차 또는 사람 등의 외부 물리력으로 인하여 훼손되는 경우가 대부분이다.In particular, the failure rate of the charger for the electric vehicle usually accounts for about 80% of the failure of the charging cable, and the cause of the failure of the charging cable is as described above, as a result of the charging cable wearing on the floor during the handling of the charging cable In most cases, it is damaged or damaged by external physical forces such as cars or people.

따라서, 종래에는 충전 케이블의 과도한 무게 및 길이로 인하여 사용자의 충전기 사용에 불편함이 따르고, 충전 케이블 손상에 의한 충전기 고장이 빈번하게 발생한다는 문제가 있었다.Therefore, in the related art, there is a problem that the user is inconvenient to use the charger due to the excessive weight and length of the charging cable, and frequent charger failure due to damage to the charging cable.
