Abstract: With the rapid development of China's new energy vehicle industry,new energy vehicles are used more and more widely,and the demand for charging and discharging is increasing. The market puts forward higher and higher requirements for the safety and convenience of charging and discharging of new energy vehicles. Sealing parts are important parts to ensure users' safety during charging and discharging. This research is mainly aimed at the design of sealing parts of new energy vehicle charging and discharging products,and a reasonable sealing structure is designed by considering multiple modes from the perspective of safety.

Key words: new energy vehicle, charging and discharging, sealing parts, safety
