Abstract

The invention relates to a tensioning type satellite-rocket connecting and unlocking mechanism, in particular to a satellite-rocket connecting and unlocking device with an upper body and a lower bodyin butt joint, and belongs to the technical field of machinery. The mechanism comprises a tensioning structure, a locking structure, an explosive bolt, a torsional spring, a pneumatic module and a hinge base. The tensioning structure is composed of two connected cylindrical shafts and a connecting part. The lower end of the tensioning structure is connected with a carrying structure hinge seat through lugs; two ends of the upper part of the tensioning structure are respectively connected with the locking structure through explosive bolts and hinges; a torsional spring is arranged at the jointof the tensioning structure and the locking structure to realize rotary unlocking of the locking structure; the joints of the tensioning structure and the explosive bolts provide downward pressure forthe stacked satellites when the satellites and the rockets are connected; during satellite-rocket connection, the ball head of the locking structure makes contact with the concave circle at the top of a stacked satellite connecting column, downward pressure is applied to the stacked satellite connecting column through locking force generated by connection with the explosive bolt, and satellite-rocket connection is achieved.

Description

technical field [0001] The invention relates to a tensioned star-arrow connection unlocking mechanism, in particular to a star-arrow connection unlocking device with upper and lower body docked, which has the characteristics of good connection rigidity, small separation impact, simple structure, reliable separation, and convenient manufacturing and processing. It belongs to the field of mechanical technology. Background technique [0002] Multi-satellite launch technology refers to the technology that uses one rocket to launch multiple satellites into the predetermined orbit. Under the conditions of carrying capacity and envelope permitting, the launch method of multiple satellites with one rocket is convenient for multiple satellites to enter orbit. Rapid networking to meet the requirements of rapid deployment of constellations. With the rapid development of micro-satellite technology, there are more and more demands for multi-satellite launch missions. [0003] The tradi...
