4. The electric vehicle charging cable management device according to claim 1, wherein the servo motor (601) is connected with a control main board (11), a control button (12) for controlling the forward and reverse rotation and the pause of the servo motor (601) is arranged on the control main board (11), an encoder (13) for detecting the number of turns of an output shaft of the servo motor (601) is installed on the output shaft of the servo motor (601), the control main board (11) displays the pull-out length of the charging cable in real time, and the control main board (11) establishes the corresponding relationship between the pull-out length of the charging cable and the charging behavior of the charging cable.
5. A management method of an electric vehicle charging cable is applied to the electric vehicle charging cable management device of any one of claims 1 to 4, and is characterized by comprising the following steps:
step 100, installing charging cables, namely spirally arranging the charging cables along the maximum range and completely storing the charging cables in an inner cavity of the pile body;
step 200, stretching and charging the charging cable, wherein the power regulating assembly drives the charging cable to be pulled out of the inner cavity of the pile body, and the charging cable is contracted inwards within the arrangement range of the inner cavity of the pile body;
step 300, the charging cable is reset and stored, the power assembly is regulated and controlled to reversely drive the charging cable to reset and recover towards the inner cavity of the pile body, and the charging cable extends outwards again within the arrangement range of the inner cavity of the pile body and recovers to the maximum arrangement range.
6. The management method of the electric vehicle charging cable according to claim 5, wherein in step 100, the charging cable is spirally installed on the inner wall of the pile body inner cavity from bottom to top, and the adjacent charging cables on the upper layer and the lower layer do not overlap.
7. The management method of the electric vehicle charging cable according to claim 5, wherein the charging cable is installed on the inner wall of the inner cavity of the pile body in a telescopic reset manner, in step 200, when the charging cable is pulled outwards, the arrangement range of the charging cable in the inner cavity of the pile body is shrunk inwards, and the charging length of the charging cable is compensated by changing from the maximum spiral arrangement to the small spiral arrangement of the redundant length.
8. The management method of the electric vehicle charging cable according to claim 5, wherein in step 300, when the charging cable is returned inward, the arrangement range of the charging cable in the inner cavity of the pile body is expanded outward, and the charging length of the charging cable in use compensates for the missing length of the charging cable from the narrow-range spiral arrangement to the maximum-range spiral arrangement.
