A link hook and latch separation mechanism for rocket stage separation

Abstract

A connecting rod hook locking type locking separation mechanism for rocket stage separation relates to the field of space technology. The mechanism comprises an upper stage connecting plate, a lower stage fixing plate and a frame, the frame is fixed on the lower stage fixing plate, the mechanism further comprises a locking assembly, a transmission assembly and a driving assembly, the locking assembly comprises a hook lock and a first fixing shaft, the hook lock is hinged to the frame through the first fixing shaft; the transmission assembly is hinged between the frame and the hook lock; the driving assembly is connected with the transmission assembly, and is used for providing a driving force to drive the transmission assembly to rotate the hook lock around the first fixing shaft to realize locking and separation of the hook lock and the upper stage connecting plate. The mechanism realizes decoupling of locking force and unlocking force, has the advantages of compact structure, high reliability and strong environmental adaptability, and is suitable for stage connection and separation of a new generation of carrier rockets.
