Abstract

The invention discloses a shock-free wrapping tape type unlocking separation mechanism, belongs to the technical field of aerospace, and aims at solving the problems of high production cost, high shock response, long working time, small load and pollution. Connecting bolts of two shock-free connection unlocking assemblies are connected with a wrapping tape type separation assembly through wrapping tape gaskets and nuts; a memory alloy barrel is heated to be recovered to the original shape; a disconnection shaft is pulled and broken into two parts; an actuation spring pushes a guide barrel to move; connecting bolts are released; and a left wrapping tape and a right wrapping tape are pushed away by a separation spring and separated from an upper supporting seat and a lower supporting seat, so that the upper supporting seat is separated from the lower supporting seat. According to the invention, the three-stage release process is achieved, so that the bearing capacity can be amplified step by step on one hand and the shock response can be minimized through step-by-step release at the same time; a tension spring and the actuation spring can effectively absorb shock generated by brittle failures of the bolts; and the shock-free connection unlocking assemblies can bear a larger clamping force and the wrapping tape type unlocking separation mechanism can bear a large load.

Description

technical field [0001] The invention relates to a non-impact strap-type unlocking and separating mechanism, which belongs to the technical field of aerospace. Background technique [0002] The spacecraft needs a variety of connection and separation mechanisms to realize space connection and unlocking functions, such as the separation of multi-stage launch vehicles, the separation of satellites and rockets, and the deployment of solar wings on satellites or spacecraft. Taking the separation of the satellite and the rocket as an example, since the satellite and the rocket are connected by multiple unlocking mechanisms before separation, multiple unlocking mechanisms are required to be able to carry the vibration load of the launch during the launch process, and multiple unlocking mechanisms are required to be synchronized and low Unlocking with impact or even without impact can realize the separation of star and arrow. Therefore, high requirements are put forward for the carry...
