In response to the call of the country, low-carbon, environmental protection, and green travel continue to advance, and the new energy electric vehicle industry has risen rapidly. With the strong support of various central support policies and various local support policies, new energy vehicles represented by electric vehicles have developed rapidly. The obvious advantage of electric vehicles is that they do not need to refuel and will not produce exhaust gas to affect the environment. With the introduction of electric vehicles, a series of infrastructure facilities such as charging guns, charging piles, and new energy adapters are well known as electric vehicles. The charging pile is a charging station for electric vehicles, and part of the exterior design is similar to the parking stopwatch. There are many types of charging piles, which are divided into floor-mounted charging piles and wall-mounted charging piles according to installation methods. According to the installation location, it is divided into public charging piles and special charging piles. According to the number of charging interfaces, it is divided into one single charging pile and one multi-charging pile to improve the efficiency and practicability of public charging piles. According to the charging method, it is divided into DC charging pile, AC charging pile and AC/DC. The charging pile can not only charge electric vehicles, but also has the functions of timing, counting electricity and counting the charging amount. The design of charging piles is a tedious process. In the early stage of charging pile design, designers first need to go through sufficient market research to find the positioning of existing products, carefully analyze the characteristics and functions of products, clarify the consumption trend of consumers, and combine users. Design needs, find innovation points and formulate design plans. In the process of charging pile design, attention should also be paid to details, comprehensive consideration of problems in all aspects, and reasonable plans should be formulated. In the process of charging pile design, in addition to considering appearance design, structural design, and hand board production, it is also necessary to consider human-machine operation, color matching, material selection, production cost, product competitiveness, etc. To ensure the landing of product design, only the design that can be produced on the ground is meaningful. Even if the perfect design cannot be completed on the ground, it is only a beautiful drawing and has no production value. After determining the appropriate plan, you can produce in small batches, create a prototype of the product, conduct user experiments and evaluations, and if problems are found, correct and improve the design plan in time, and make sure that there are no problems before mass production.
