Abstract

The invention discloses a thermally-induced fusing steel ball lock separating mechanism. The separating mechanism comprises a shell (1), an unlocking column (2), an unlocking spring (3), a restraining rope (4), a heater (5), a steel ball (6), a lock cap (7), a check ring (8), a limiting ring (9) and a limiting spring (10). Locking and releasing of the lock cap are achieved through the relative position relation among the shell, the unlocking column and the lock cap, an unlocking spring is installed between the unlocking column and the shell, and a restraining rope is bound between the unlocking column and the shell. The restraint rope restrains the position between the unlocking column and the shell, so that the separation mechanism is in a locked state, and the spring is in a compressed state; a heater is installed on the restraint rope, the heater is powered on, the restraint rope is fused, the unlocking spring pushes the unlocking column to move by a certain distance, and the separation mechanism is changed into an unlocking and releasing state from a locking state. The separation mechanism has the characteristics of simple structure, light weight, low impact, low cost, wide temperature adaptability, high locking and unlocking reliability and the like.

Description

technical field [0001] The invention relates to a separation mechanism, in particular to a non-pyrotechnic separation mechanism. Background technique [0002] In recent years, micro-satellites have developed rapidly. Various structural products on them, such as small expandable solar wings, antennas, etc., need to be compressed in the folded state to withstand the load of the launch section. After entering orbit, they need to be separated and released so that the products can Expand to a predetermined position or shape. Traditional spacecraft often use pyrotechnic separation devices, which have the characteristics of large carrying capacity and reliable separation, but at the same time have disadvantages such as heavy weight, high cost, and large unlocking impact, which cannot well meet the needs of microsatellites. Therefore, it is necessary to develop a lightweight, low-cost, high-performance separation mechanism. Contents of the invention [0003] The purpose of the p...
