Ventilation structure of electric vehicles

Abstract

The light cover reveals the ventilation structure in which the air-fluid phase separation chamber (100), with an opening to the outside environment (105), is formed between the first assembly (3 a) and the lever (51) by installing the power assembly (P) into the lever (51) at the first assembly (3 a). Because the gas-liquid phase separation chamber (100) is connected to the air-venting chamber (80) through the flexible pipe (120) and the air-venting chamber (80) is connected to the gear chamber (43), the pressure in the gear chamber (43) can be released to the outside environment after the gas is directed to the gas-liquid phase separation chamber (100). Therefore, even when rainwater or similar objects enter the gas-liquid phase separator (100) through the opening to the outside environment (105), the gas-liquid phase separator (100) acts as a water reservoir, preventing rainwater or similar objects from burning back into the gear compartment (43) and improving the watertightness of the ventilation structure.
