A dual shaft driven hinge
By using a passively driven dual-axis hinge design, the synchronous deployment and self-locking of the spacecraft's deployable device are achieved through a spring and mechanical structure. This solves the problems of low synchronization and locking accuracy in existing technologies and achieves a highly reliable deployment effect that is small in size, light in weight, and free from electromagnetic interference.
