The invention discloses a variable-diameter internal driving type sleeve unfolding method, and belongs to the technical field of variable structure space remote sensors, and the method is based on a wheel type driving assembly, a variable-diameter pre-tightening assembly capable of enabling the wheel type driving assembly to abut against the inner wall of a sleeve, and a control system for feeding back the wheel type driving assembly and the abutting state. The method comprises the following steps that S1, a variable-diameter pre-tightening assembly is fixedly connected with the lower portion of an innermost sleeve or the lower portion of an outermost sleeve, and a wheel type driving assembly is installed on the variable-diameter pre-tightening assembly; s2, a pre-tightening system ensures that the wheel type driving assembly makes real-time contact with the inner wall of the sleeve to be unfolded; s3, the driving system controls the wheel type driving assembly to rotate, the sleeve is unfolded step by step, and the machine is stopped after the sleeve is completely unfolded, the method has the advantages of being simple, reliable, extensible, compact and high in precision, and the method can be used for all occasions where a sleeve type unfolding mechanism is used, especially the field of space remote sensing with the high requirement for unfolding precision.
