It can be fixed on the ground or on the wall and installed in public buildings, shopping malls, public parking lots, residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. The current charging pile technology is relatively mature, and the safety of the charging process can be fully guaranteed. However, the charging pile may still be damaged due to factors such as physical collision between the charging pile and the electric vehicle.

[0003] In the operation of existing charging piles, in addition to the damage caused by collisions, customers fail to plug the charging gun back in time after use, and place it on the ground at will, or fail to plug it back into the charging pile according to the standard, causing the charging gun to fall.

When it is judged that the current charging gun is in an idle state and has not been inserted back into the hanging slot 36, the recycling judgment module can send a control signal to the recycling control module, and the recycling control module controls the recycling component to recycle the charging gun to the bottom of the charging gun temporary storage room 3, and report to the charging station and the virtual power plant data center through the early warning module, and then the charging station sends information to the customer to remind the customer to plug the charging gun back, or dispatch maintenance personnel offline to the charging station where the charging pile is located to reset the charging gun.

[0058] In summary: the automatic voltage-responsive charging pile is provided with a recycling component, so that when the system detects that the rear end 5 and the front end 6 of the charging gun are in an idle state and have not been inserted back into the hanging slot 36, the recycling motor 8 drives the recycling wheel 10 to rotate through the recycling shaft 9, and then drives the charging cable 4 to be lifted upward through the meshing storage teeth 11 and the tooth grooves 12, so that the charging cable 4 is retracted into the cable storage chamber 2 for stacking under the limiting action of the guide side cable 13 and the guide through hole, so that the other end of the charging cable 4 drives the rear end 5 and the front end 6 of the charging gun to be gradually retracted to the bottom of the charging gun temporary storage chamber 3 for temporary storage, thereby realizing the timely recycling of the charging gun, effectively avoiding the problems of the charging gun being crushed by vehicles and washed by rain, and extending its service life. By setting a steering motor 14, during daily use, customers can control the steering motor 14 through the screen of the charging pile body 1 or the mobile phone APP to drive the front end 6 of the charging gun and the rear end 5 of the charging gun to rotate relative to each other, so as to obtain the most suitable angle for the current vehicle and enjoy better customized services. At the same time, when the front end 6 of the charging gun is recycled, the steering motor 14 will control the front end 6 of the charging gun to rotate until it is on the same axis as the rear end 5 of the charging gun, thereby facilitating recycling and reducing the occurrence of bumps and jams caused by the angle between the rear end 5 of the charging gun and the front end 6 of the charging gun during recycling. By setting a protective cover 22, the front end 6 of the charging gun and the rear end 5 of the charging gun are kept on the same axis during recycling, and the steering motor 14 drives the control The control shaft 24 rotates, and then the traction rod 20 is driven to slide inward through the meshing action of the rotating gear 25 and the protective box 17, thereby driving the protective cover 22 to move toward the front end 6 of the charging gun and buckled on the front end 6 of the charging gun, so that the terminals inside the front end 6 of the charging gun are protected inside the protective cover 22, thereby avoiding the friction between the end face of the front end 6 of the charging gun and the ground and the contact with rain, dust and other debris during the recycling process. By setting the protective shell 30, the rotating gear 25 will synchronously drive the meshing second gear rod 27 to slide in the opposite direction to the protective box 17 during the rotation process, thereby driving the protective shell 30 to slide on the rear end 5 of the charging gun toward the front end 6 of the charging gun through the slide 29 until the protective cover 22 is buckled on the front end 6 of the charging gun, and the protective The cover 22 will stop at the junction of the charging gun rear end 5 and the charging gun front end 6, and the connection structure of the charging gun rear end 5 and the charging gun front end 6 will be covered and protected inside the protective shell 30, thereby improving the connection strength between the charging gun rear end 5 and the charging gun front end 6 during the recovery process. By setting the reinforcing pin 32, when the second gear rod 27 and the protective box 17 slide in the opposite direction, the second gear rod 27 will drive the reinforcing pin 32 to move toward the charging gun front end 6 until the reinforcing pin 32 is inserted into the slot 33, thereby supporting the charging gun rear end 5 and the charging gun front end 6. In conjunction with the protective shell 30, the connection status of the charging gun rear end 5 and the charging gun front end 6 can be strengthened from both sides. In the process of dragging and recycling the charging cable 4,The rear end 5 and the front end 6 of the charging gun are effectively prevented from being hit by debris on the ground, resulting in connection breakage and line damage. By setting the wear-reducing roller 31 and the loudspeaker 34, during the recycling process, the wear-reducing roller 31 can cooperate with the protective shell 30 to reduce the direct contact between the rear end 5 and the front end 6 of the charging gun and the ground, thereby greatly reducing the wear of the rear end 5 and the front end 6 of the charging gun, and the loudspeaker 34 can broadcast warning voices to the surroundings from the charging pile body 1 and the rear end 5 of the charging gun, respectively, so as to remind the surrounding personnel and vehicles to be careful not to damage the charging gun, and at the same time remind the users who are still nearby to plug the charging gun back. By setting the fan 37, when the recycling motor 8 controls the recycling of the charging cable 4, the recycling motor 8 can drive the fan 37 to rotate and blow air through the recycling shaft 9 and the transmission pulley group 39, so as to blow and clean the part of the tooth groove 12 of the charging cable 4 that is still at the bottom of the partition 7, so that the dust, lint and other debris attached to or accumulated on the charging cable 4 and the tooth groove 12 are blown off. In this way, the charging cable 4, the cable storage room 2, and the charging gun temporary storage room 3 are kept clean, and external debris is prevented from affecting the meshing of the tooth groove 12 and the storage tooth 11. The automatic voltage response charging pile system respectively detects the working voltage of the current charging gun, the order time being served by the charging pile body 1, and the plugging state of the hook slot 36 and the charging gun in real time by setting a voltage detection module, an order time limit module, and a plugging state detection module, and collects the above information and provides it to the recycling judgment module for judgment. When it is judged that the current charging gun is in an idle state and has not been plugged back into the hook slot 36, the recycling judgment module can send a control signal to the recycling control module, and the recycling control module controls the recycling component to recycle the charging gun to the bottom of the charging gun temporary storage room 3, and reports to the charging station and the virtual power plant data center through the early warning module to achieve site-station collaboration, and then the charging station sends information to the customer to remind the customer to plug the charging gun back, or dispatch maintenance personnel to go offline to the charging station where the charging pile is located to reset the charging gun.
