[0002] Two-wheeled electric vehicles are an important means of transportation for short-distance travel. Charging two-wheeled electric vehicles generally involves connecting the power plug to the battery to replace the battery. However, traditional charging plugs and sockets lack an effective sealing design, making them prone to water ingress in rainy or humid environments, leading to poor contact, short circuits, or oxidation and corrosion. Furthermore, existing charging plugs have limited functionality and cannot simultaneously meet charging and discharging needs (such as external power supply).

[0003] For example, the patent with authorization announcement number CN222422446U describes a female connector plug and connector for electric vehicles, including a housing, wiring assembly and pressing assembly. It locks the plug and socket by engaging with the corresponding holes or slots on the socket to prevent the plug and socket from being disconnected by external disturbances while connected, thus ensuring the stability of the plug and socket connection and the reliability of electric vehicle charging and discharging operations. However, it does not perform corresponding sealing operations, which makes it easy for water to enter in rainy or humid environments, leading to poor contact, short circuits or oxidation corrosion, reducing the practicality of the device.
