The invention discloses an electric vehicle charging interface with a dust-proof function, comprising a panel which is provided with an accommodating cavity. A charging jack is arranged in the middle of the accommodating cavity. A baffle plate used to cover the accommodating cavity is hinged to the upper end of the accommodating cavity through a torsional spring, the baffle plate is shaped as a circular arc, and the inner side wall of the baffle plate is provided with two chutes. Projections matching the chutes are fixed to the two ends of an adjusting rod respectively. Each of the two ends of the adjusting rod is connected with one end of a piece of rain cloth, and the other end of each piece of rain cloth is connected with the bottom end of the accommodating cavity. The blocking object of the rain cloth is not confined to rain. When the charging jack is closed, the folded rain cloth can completely fill the two sides of the accommodating cavity, namely, the rain cloth and the front end of the baffle plate effectively seal the whole accommodating cavity. Therefore, a lot of dust on a dusty road section or a muddy road section is prevented from pouring in from the gap between baffle plate and the accommodating cavity, and stable input of the charging jack on the vehicle panel is ensured when charging is needed.
