Key points of charging gun design

Charging gun It is the charging interface of new energy electric vehicles and an important supporting charging equipment to promote the development of new energy electric vehicle industry. With the rapid development of new energy electric vehicle industry, the industry of charging equipment such as charging pile and charging gun is also booming. There are many charging gun products in different forms, simple and beautiful, safe and comfortable to use, providing users with higher and higher quality charging experience.

1、 Charging gun Rich design

Among professional industrial design companies, such as Guangdong Wanlian technology through research on charging pile Charging gun National standards such as conduction charging system, conduction charging connection device, AC charging interface, DC charging interface and communication protocol, clarify the national standards for the design of charging pile and charging gun, and study and design DC charging gun, AC charging gun, slow charging gun, fast charging gun, American standard charging gun, European standard charging gun and national standard charging gun in combination with ergonomics.

2、 Charging gun Humanization of design

（1） Charging gun The structural scheme should be designed into two different forms according to different requirements: A. separate structure (convenient assembly, rich shape and slightly poor strength); b. Integrated structure (better waterproof performance and overall strength, worse assembly convenience)

(2) Ergonomically, the button is flat and set in a convenient position; The handshake part is designed at a 75 ° angle to avoid interference between charging guns, charging piles or vehicles during operation. In terms of hand shape, it is designed according to different hand sizes of Asians, Europeans and Americans, and the size is between 85mm-100mm. For example, the national standard AC vehicle plug of Shenglan technology evg12-xxp5 model is independently developed and designed, based on the "minimalist" design concept, generous and concise, and elegant appearance and surface color matching.

(3) For material selection, the gun body mostly adopts outdoor PC, PC + PPT, and the gun head mainly adopts PPT and PA66, which is resistant to high temperature, low temperature and rolling. Generally, it will not fade after ten years of outdoor use.

(4) Simulation analysis is used to find the possible design defects in the production or use of products in advance, so as to improve the quality and efficiency of product development.

3、 Charging gun New and beautiful shape

along with Charging gun With the increasingly fierce market competition, market homogenization is inevitable. More and more enterprises take the design of charging gun as a breakthrough point for the market, and pay more and more attention to the novelty and beauty of the appearance of charging gun. For example, this streamlined charging gun is inspired by speed and is based on the shape curve of animals and people running. Through the design method of abstract Association, with smooth and rhythmic line design, the product is endowed with the modeling style of fashion technology, which gives people a fast and modern visual experience as a whole, and reflects the functional characteristics of safe and fast charging of charging gun.
