The invention discloses a symmetrical multi-connecting-rod electrically-driven aircraft landing gear structure which comprises a main driving mechanism, a follow-up mechanism and a main supporting column. The driving end of the main driving mechanism is hinged to the main supporting column, the top of the main supporting column is hinged to the machine body, and the bottom of the main supporting column is connected with tires. The follow-up mechanism comprises a first four-bar mechanism, a second four-bar mechanism, a right supporting column rocker and a left supporting column rocker, the first four-bar mechanism and the second four-bar mechanism are symmetrically arranged, one end of the first four-bar mechanism and one end of the second four-bar mechanism are hinged to the machine body, and the other end of the first four-bar mechanism and the other end of the second four-bar mechanism are hinged to a fixed support on the main supporting column. End connecting rods, close to the machine body, of the first four-bar mechanism and the second four-bar mechanism are hinged to the main supporting column through a right supporting column rocker and a left supporting column rocker respectively. The structure is light and compact, reliability, stability and safety are guaranteed, the requirement of an electric drive mode for high power is lowered, the stable, reliable and light supporting requirements of the aircraft landing gear are met, and good practicability is achieved.
