This invention provides a single-degree-of-freedom deployable light shield to address the technical problem that existing rigid deployable light shields, with their columnar or planar configurations, are difficult to adapt to the obliquely tapered configuration required for large observation fields. The single-degree-of-freedom deployable light shield provided by this invention innovatively couples two sets of equivalent cranks and equivalent connecting rods connected by elastic drive hinges to a planar multi-stage scissor mechanism. This transforms the linear motion of the planar multi-stage scissor mechanism in the plane into the linear motion of the slider required by the equivalent crank-slider mechanism. Simultaneously, the symmetrically arranged equivalent crank-slider mechanisms on both sides provide in-plane coupling constraints for the planar multi-stage scissor mechanism, limiting its multiple degrees of freedom and forming a single-degree-of-freedom deployable mechanism. This single-degree-of-freedom deployable mechanism, in conjunction with the elastic drive hinges and locking device, achieves the deployment of the obliquely tapered light shield using fewer driving force interfaces while ensuring stability during the deployment process.
