[0002] The intelligence of electric vehicles is the trend of the future. With the continuous improvement of unmanned driving technology, the automatic charging technology of cars has also been born. At present, major charging piles and vehicle manufacturers across the country have begun to study automatic charging of cars and have launched their own automatic charging solutions. For DC automatic charging equipment, since the DC gun wire is thicker and heavier, it is usually equipped with a wire take-up device.
[0003] At present, most of the automatic charging robotic arms on the market are one-way charging, that is, one robotic arm is only responsible for charging one parking space. Since automatic charging equipment is relatively expensive, this will cause a waste of resources. If one robotic arm can charge the cars in the two parking spaces on its left and right at the same time, this can greatly improve the utilization rate of automatic charging, thereby spreading the equipment cost. However, if you need to charge the cars in the left and right parking spaces at the same time, you need two sets of charging guns and gun lines. Since the DC gun line is thick and heavy, the gun line will swing when the robotic arm is in motion. Therefore, it is necessary to design a wire-retracting device that can retract and release two gun lines at the same time and avoid interference between the gun lines when they are in motion.
