[0002] Traditional fixed charging pile is gradually replaced by more advanced and flexible overhead line charging operation due to its inherent disadvantages. In practical application scenarios, the limitations of fixed charging piles are increasingly prominent. It is not only fixed in installation position, but also difficult to meet the charging needs of new energy vehicles under different parking layouts. Moreover, the cost of consumables is high, and the subsequent maintenance cost is too heavy for operators to bear.

[0003] In view of this, our company follows the industry trend and is committed to creating a new mobile power solution for new energy charging guns. At the same time, the existing charging box generally uses plug-in power supply method, which has exposed a series of problems that need to be solved in the daily use process. Each time the charging box is used, the charging box has to be operated repeatedly, and the frequent plugging and unplugging action causes severe friction between the plug and the socket. Over time, it inevitably causes serious wear and tear of the plug and socket. As the degree of wear and tear deepens, hidden troubles such as poor contact gradually breed. Once such problems occur, the charging box will not be able to get power normally, which will directly interfere with the charging function of the entire device, bring poor user experience to new energy vehicle users, and even delay their travel arrangements.

[0004] After design adopts magnetic attraction contact power supply, it will produce force instantaneously when the charging box contacts power supply and peels off power supply. Long time will cause loosening of device screws, short time will require maintenance, which is very inconvenient. Utility model content
