The invention discloses an aerospace vehicle cabin door folding and unfolding mechanism based on cable folding and unfolding. The aerospace vehicle cabin door folding and unfolding mechanism comprises a pulley block installed on one side of the free edge of a cabin door and a cabin door rotation driving device installed at the position of a cabin door rotating shaft. The pulley block comprises a fixed pulley block installed on a supporting structure below the free edge of the cabin door and a movable pulley block installed on the free edge of the cabin door. The supporting structure is fixedly connected with one end of the cable, and the other end of the cable penetrates through the pulley block and then is connected with the cable take-up and pay-off driving device. The cabin door rotation driving device is used for providing rotation torque in the rotating opening direction of the cabin door; when the cable take-up and pay-off driving device takes up the cable, the cabin door is rotationally closed, and when the cable take-up and pay-off driving device pays off the cable, the cabin door is rotationally opened under the action of rotating torque. The invention has the characteristics of light weight, small occupied space, simple and reliable structure and accurate opening control.
