The invention relates to a vertical damping and buffering mechanism for a rocket body with large buffering capacity in a small space, and belongs to the technical field of carrier rocket reuse. The vertical vibration reduction buffering mechanism comprises an unfolding piece, a locking piece, a connecting piece, a buffering device, a landing piece and an unlocking piece, and through the ingenious structural design, the vertical vibration reduction buffering mechanism is light in weight, easy to operate and replace, capable of effectively improving mechanism installation, replacement and maintenance efficiency, capable of reducing machining cost and high in reliability. The vertical vibration reduction buffer mechanism is overturned, locked and stored in the tail section of the rocket body at the rising section of the rocket and does not protrude out of the rocket body, devices such as a pneumatic cover do not need to be additionally arranged, the external space of the rocket body is not occupied, the pneumatic appearance of the rocket body is maintained, and the occupied internal space of the rocket body is small when the vertical vibration reduction buffer mechanism is stored; and a layered crushing buffering method is preferably adopted, so that the structure size can be reduced on the premise of ensuring the bearing and buffering performance.

    本发明涉及一种小空间内大缓冲能力箭体垂直减振缓冲机构,属于运载火箭重复使用技术领域;该垂直减振缓冲机构包括展开件、锁定件、连接件、缓冲装置、着陆件和解锁件,通过巧妙的结构设计具有质量轻、易操作、易更换,可有效提高机构安装、更换、维护效率,降低加工成本,并且该垂直减振缓冲机构在火箭上升段翻转锁定收于箭体尾段内部,不突出于箭体外部,无需额外设置气动罩等装置,不占用箭体外部空间,维持箭体气动外形,收起时占用的箭体内部空间也较小;并且优选采用分层压溃缓冲方法可在保证承载和缓冲性能的前提下减小结构尺寸。
