The invention discloses a motor-driven sealing mechanism for an aircraft external hanging point. The motor-driven sealing mechanism comprises a shell (1). A support frame is arranged on the inner side of the shell (1) and is overall of a rectangular frame structure defined by four inside sliding rails (3) and two gear supports (4). A cover plate (10) is fixed to the upper top face of the support frame, and the middle of the support frame is symmetrically provided with sealing plates (11) in close butt joint and provided with a drive device for driving the sealing plates (11) to be opened and closed. The middle of the shell (11) is concaved inwards to form a mounting groove a, and two parallel mounting support rods (17) are welded to the middle of the mounting groove a. The motor-driven sealing mechanism is simple in structure and convenient to mount; when a hanger is mounted, ground personnel open the sealing plates through a switch, and then the sealing plates are kept in the open state; and after the hanger is placed, the sealing mechanism is automatically closed, and use is quite convenient.
