[0002] Electric vehicles, as a promising green mode of transportation, are poised for rapid adoption, with an exceptionally large market potential. Against the backdrop of a severe global energy and environmental crisis, the Chinese government is actively promoting the application and development of new energy vehicles. Charging / battery swapping stations, as essential supporting infrastructure for the development of electric vehicles, offer significant social and economic benefits. A campaign to build electric vehicle charging stations has already begun across China.

[0003] Most charging piles on the market are currently fixedly installed on the outdoor ground, which not only takes up space but is also prone to collisions with vehicles. Furthermore, long-term exposure to sunlight will reduce the lifespan of the charging piles. The operating interface of the charging piles is small, and because users have different heights, the fixed height of the charging piles results in a poor user experience for a large number of users. To address this, an automatic lifting device for charging piles based on a screw linkage mechanism is proposed. Utility Model Content
