Redundant unlocking and sequential control release mechanism for small satellite launching

Abstract

The invention relates to a redundant unlocking and sequential control release mechanism for small satellite launching, and belongs to the technical field of rocket launching. The device comprises a cabin door, a frame body, a hinge part, a push plate, a thrust spring, four sliding rails, a limiting device, a connecting rod, a pressing plate and an electromagnetic lock; the top of the frame is open; the cabin door is arranged at the top opening of the frame body; the hinge part is arranged at the joint of the cabin door and the frame body; the electromagnetic lock is arranged on the side wall of the frame body; the four sliding rails are arranged at the corners of the four side walls in the frame body in the axial direction. The thrust spring is arranged at the bottom end in the frame body;the push plate is horizontally arranged at the top end of the thrust spring; the pressing plate is arranged at the bottom end in the frame body; the connecting rod is vertically arranged at the top end of the pressing plate; the limiting device is arranged at the top of the connecting rod; the limiting device drives the pressing plate to act together through the connecting rod; The invention discloses an external cubic small satellite releasing device where the electromagnet serves as a driving power source and the redundant unlocking function is achieved, the reliability of the unlocking device is improved, and then the launching success rate of an external cubic small satellite is increased.

Description

technical field [0001] The invention belongs to the technical field of rocket launch, and relates to a release mechanism for redundant unlocking and timing control of small satellite launch. Background technique [0002] With the development of micro-nano technology and the promotion of application requirements, micro-nano satellites have been deeply studied and widely used in many fields such as scientific research, national defense and commercial use due to their advantages of small size, low power consumption, short development cycle, and low cost. In order to enable universities and scientific research institutions to have more opportunities to participate in space science practice, external cube small satellite refers to a tiny satellite made with special design standards (by Jodi Prig Saur of California Polytechnic State University, CalPoly). The professor formulated the initial relevant standards. The standard external cube satellite adopts the "1U" structure, that is...
