The charging gun scheme for new energy vehicles designed for my friend company was originally scheduled to adopt the previous hand holding method and the temporary change behind to use the direct holding method, so the design stopped at the current state. Two days ago, I turned it out in the computer and communicated with everyone. The overall structure is compact, the appearance is relatively simple and comfortable, and the overall design conforms to ergonomics. The height of the installation position and the stress point are considered in the man-machine. The comfortable grip of the handle is emphasized. The handshake is made of soft rubber to increase its anti-skid and good experience comfort.
