The invention discloses a solar sailboard unfolding control mechanism which comprises a three-way pressing plate. A strip-shaped through hole is formed in the three-way pressing plate, the strip-shaped through hole is located in the middle of the side face of the long straight part of a right-angle hook end of the three-way pressing plate, and a rotating shaft is installed in the strip-shaped through hole. The three-way pressing plate is connected with a sailboard auxiliary pressing plate through a rotating shaft; a torsional spring is arranged on the rotating shaft in a communicating mode, atorsional spring mounting hole boss is arranged on one side face of the three-way pressing plate, one end of the torsional spring is fixed in a torsional spring mounting hole of the torsional spring mounting hole boss, and the other end of the torsional spring is arranged on the lower side of an auxiliary pressing plate; the sailboard auxiliary pressing plate is provided with a rotating shaft mounting threaded hole, and the front end of the rotating shaft is provided with a thread and is in threaded connection with the rotating shaft mounting threaded hole of the sailboard auxiliary pressing plate. The mechanism has the advantages of simple structure, few components, good integrity, small volume, light weight and easiness in installation; the torsional spring is used for fixing again, double guarantees are achieved, the mechanism is prevented from vibrating and disengaging from the body in the spacecraft launching process, and reliability is high.
