The invention belongs to the field of intelligent parking, and discloses an overhead, cable-free and high-load-bearing charging pile which comprises a motor and a first lead screw. The system further comprises a first fixing plate, a second fixing plate, a first sleeve, a second sleeve, a third sleeve, a fourth sleeve, a second lead screw and a third lead screw, a motor box is fixed to the first fixing plate, the motor is fixed in the motor box, and the first sleeve, the second sleeve, the third sleeve and the fourth sleeve are electrically connected through conductive parts. One end of each conductive part is connected with the charging interface, the other end of the conductive part is connected with a power supply interface, the charging pile is characterized in that the charging pile is realized based on an electric push rod, the electric push rod has the characteristics of multiple sections capable of synchronously lifting to realize stable pushing of an overweight object (generally greater than 500kg), and meanwhile, the conductive electric push rod is free of a wire and the charging operation of the electric vehicle is realized. The invention further discloses an intelligent parking system.
