The invention discloses an unfolding mechanism of a variable-configuration wing, and belongs to the technical field of aircraft design, the unfolding mechanism comprises a power mechanism for driving the variable-configuration wing to change the configuration and a transmission structure connected with the variable-configuration wing, the transmission structure comprises an upper cone, a lower cone, an outer cone sleeve and a rocker arm, the outer cone sleeve is of a fixedly arranged hollow structure, and the rocker arm is of a hollow structure. The inner diameters of the conical cavities are sequentially increased from the middle to the two ends to form an upper conical cavity and a lower conical cavity respectively; the lower cone, the upper cone and the rocker arm are fixedly connected into a whole and are rotatably connected in the outer cone sleeve, the lower cone is connected with the variable-configuration wing, the rocker arm is connected with the output end of the power mechanism, and the rocker arm rotates around the axis of the conical surface under the action of the power mechanism so as to drive the variable-configuration wing to synchronously rotate to change the configuration. Through the design of the conical surface sliding bearing structure, the gap between the wing and the fuselage can be effectively eliminated under the condition that the cross-shaped wing rotates relative to the fuselage, and it is ensured that the pneumatic configuration is accurate.
