In the above solution, only side wall protection plates are installed on both sides of the charging piles. Although this provides a certain degree of protection, its protection range is quite limited. In actual scenarios, vehicles may approach charging piles from multiple directions, so this protection method obviously has obvious limitations and shortcomings. Utility Model Content
