一种用于航天器的仪器设备或人员着陆的缓冲装置

本发明公开了一种用于航天器的仪器设备或人员着陆的缓冲装置，包括，动力组件通过螺纹与支撑组件相连；支撑组件的内部形成圆形气体通道；缓冲组件通过螺纹压紧到接口组件的端面，使缓冲组件、接口组件、提升锁定组件成为一体，三者一同实现提升；该缓冲组件包括锥环、薄壁金属管及导向简，且缓冲组件是套接在支撑组件上，其最里一层为导向筒，导向筒外套接薄壁金属管，在导向筒靠近着陆方向的一端固定有锥环；在着陆瞬时，航天器受到的冲击通过接头作用到缓冲组件上，薄壁金属管依次通过锥环，发生扩径变形；初始锁定组件通过螺纹与支撑组件相连。本发明的缓冲装置，结构简单，性能稳定，提高了航天器及其仪器设备或人员着陆的可靠性和安全性。

Bufferingdevice for landing of instrument equipment or staff of spacecraft

Theinvention discloses a buffering device for landing of instrument equipment orstaff of a spacecraft. A power assembly is connectedwith a supporting assembly through threads. A circular gas channel is formed inthe supporting assembly. A buffering assembly is pressed to the end face of aconnector assembly through threads, so that the buffering assembly, theconnector assembly and a lifting and locking assembly are integrated and can belifted together. The buffering assembly comprises taper rings, a thin-wallmetal tube and a guide barrel, the supportingassembly is sleeved with the buffering assembly, the guide barrel is located atthe innermost layer and sleeved with the thin-wall metal tube, and the taperrings are fixed at the end, close to the landing direction, of the guide barrel.The impact on the spacecraft acts on the buffering assembly through a connectorat the moment of landing, and the thin-wall metal tube sequentially passesthrough the taper rings to generate diameter-expanding deformation; and aninitial locking assembly is connected with the supporting assembly throughthreads. The buffering device is simple in structure and stable in performance,and reliability and safety of landing of the spacecraft and the instrumentequipment or staff thereof are improved.
