Electric vehicle rapid charging apparatus having sensor for controlling automatic pull-out of charging cable

An electric vehicle rapid changer, comprising:

• a main body including a connector holder provided on one side of the main body and a cable connection part provided at a first predetermined height;
• a cable inlet/outlet part including a plurality of rotating rollers and fixedly coupled to the main body at a second predetermined height;
• a charging cable having a leading end portion in which a connector connected to a connection inlet of an electric vehicle is provided, a rear end portion fixedly coupled to the cable connection part, and an intermediate portion coupled to the cable inlet/outlet part to be inserted between the plurality of rotating rollers, wherein the charging cable extends downward between the cable connection part and the cable inlet/outlet part at a length;
• a sensor part including a first sensor configured to sense a coupling between the connector of the charging cable and the connector holder of the main body, and a second sensor configured to sense a coupling between the connector of the charging cable and the connection inlet of the electric vehicle, the sensor part configured to sense a charging request signal or a charging stop signal when using the charging cable;
• and
• a control part configured to control a driving of the cable inlet/outlet part according to the charging request signal or the charging stop signal sensed by the sensor part,
• wherein the cable inlet/outlet part includes guide pins arranged on a front side or a rear side of the plurality of rotating rollers to guide the charging cable to move between the plurality of rotating rollers at a normal position, and is configured to continuously discharge or collect the charging cable by a driving of the plurality of rotating rollers, and
• wherein each of the guide pins include:
• a pair of vertical guide fins arranged on right and left sides of the charging cable to prevent the charging cable from being displaced in a lateral direction, and a pair of horizontal guide fins arranged on upper and lower sides of the charging cable to prevent the charging cable from being displaced in a vertical direction,
• wherein, when the sensor part senses the charging request signal, the cable inlet/outlet part is configured to move upward the charging cable, which has been discharged downward between the cable connection part and the cable inlet/outlet part, by the driving of the plurality of rotating rollers such that the charging cable is discharged to a front side of the cable inlet/outlet part, and when the sensor part senses the charging stop signal, the cable inlet/outlet part is configured to move downward the charging cable between the cable connection part and the cable inlet/outlet part by the driving of the plurality of rotating rollers such that the charging cable is collected to an origin position;
• wherein the sensor part further includes a third sensor configured to sense whether or not the charging cable is abnormally discharged by an external force;
• and
• wherein, when the third sensor senses the charging cable being abnormally discharged, the control part is configured to stop the driving of the cable inlet/outlet part to prevent the charging cable from being discharged.
