The invention relates to the technical field of aerospace, in particular to a locking and releasing mechanism based on shape memory reversible glue. The embodiment of the invention provides a locking and releasing mechanism based on reversible glue, the locking and releasing mechanism is used for locking and releasing a spacecraft part, the spacecraft part is provided with a groove, the locking and releasing mechanism is arranged in the groove, the locking and releasing mechanism comprises a spring, a piston and shape memory polymer reversible glue, the piston is arranged in the groove through the spring, and the shape memory polymer reversible glue is arranged in the groove. The shape memory polymer reversible glue is arranged on the face, away from the spring, of the piston. When locking is needed, the multiple pistons located on different spacecraft parts are attached through shape memory polymer reversible glue, and then the locking function is achieved. When release is needed, the shape memory polymer reversible glue is heated to lose dry viscosity, pistons on different spacecraft parts are released, and then the release function is achieved. The locking and releasing mechanism is simple in structure, small in size, small in impact, light in weight and low in cost.
本发明涉及航空航天技术领域,特别涉及一种基于形状记忆可逆胶的锁紧释放机构。本发明实施例提供了一种基于可逆胶的锁紧释放机构,用于锁紧释放航天器件,航天器件设置有凹槽,锁紧释放机构设置于凹槽,锁紧释放机构包括弹簧、活塞和形状记忆聚合物可逆胶,活塞通过弹簧设定在凹槽内,形状记忆聚合物可逆胶设置在活塞远离弹簧的面上;需要锁紧时,使分别位于不同航天器件上的多个活塞通过形状记忆聚合物可逆胶贴合,进而实现锁紧功能;需要释放时,加热形状记忆聚合物可逆胶,使形状记忆聚合物可逆胶失去干粘性,释放不同航天器件上的活塞,进而实现释放功能。本发明能够提供一种机构简单、体积小、冲击小、质量轻、成本低的锁紧释放机构。
