The invention discloses a four-connecting-rod unfolded-structure flexible solar wing. In an unfolded state, connecting rods of the solar wing are used as two force members to serve as rigid supporting components for an upper box plate and a lower box plate. Thus, the beneficial effects of being light in weight and insensitive in joint gap are achieved. By means of a four-connecting-rod mechanism, the box plates are parallel to a main unfolded mechanism in a folded state, and the purpose of reducing folding envelopes is achieved. A belt spring mechanism is arranged in the connecting-rod mechanism to replace a traditional shaft pin type hinge, so that the beneficial effect of being light in weight is achieved. A quick locking mechanism is arranged in an upper connecting-rod mechanism, so that the upper box plate can form a triangular stable system after being unlocked. According to the four-connecting-rod unfolded-structure flexible solar wing, the scheme of spring driving and viscous damper speed reducing is utilized to replace the scheme of driving a hinge through a motor, so that the four-connecting-rod unfolded-structure flexible solar wing has the beneficial effects of being simple, reliable and light in weight. The locking mechanism is provided with allowance self-adapting design, so that the size deviation caused by processing errors and loaded transformation is compensated, and the normal functions are not affected.
