The invention discloses a multifunctional aircraft intelligent undercarriage device which comprises a tire, the tire is rotationally supported on a main force bearing rod, the main force bearing rod is supported on a main rod support in a swinging mode, a telescopic supporting rod is hinged to one side of the main force bearing rod and movably supported on a supporting rod damping cylinder, the supporting rod damping cylinder is supported on a supporting rod support in a swinging mode, and the telescopic supporting rod is hinged to the other side of the main force bearing rod. A retractable telescopic arm is hinged to the telescopic supporting rod, the retractable telescopic arm is movably supported on a retractable swinging cylinder, the retractable swinging cylinder is supported on a swinging arm support in a swinging mode, a retractable driving device is installed on the swinging arm support, and the output end of the retractable driving device is connected with the retractable swinging cylinder. The main force bearing rod is a hollow pipe fitting, a piezoelectric sensor is arranged on the inner wall of the main force bearing rod, and the piezoelectric sensor is electrically connected with the flight control device and the folding and unfolding indicator lamp. The multifunctional intelligent undercarriage device for the airplane has an intelligent folding and unfolding function, also has a good damping effect and is simple in structure.
