Abstract

The invention relates to a leg type landing and buffering device capable of being repeatedly used. The leg type landing and buffering device is characterized in that foot pads are connected with support leg main supporting columns through ball hinge connecting heads, metal rubber blocks are arranged between ball hinges and the foot pads, one-way dampers and long springs are arranged between innersleeves and outer sleeves, the one-way dampers do not have damp in the compression process and have damp in the stretching process, the long springs compress so that impact kinetic energy can be stored, after the maximum compression amount is reached, the one-way dampers work, the springs slowly restore to the original lengths, so that the attitudes of landing legs are restored, a load box is connected with an upper frame and a lower frame through a CR-type steel wire rope shock absorber, and is connected with an outer cylinder through a GS-type steel wire rope shock absorber, and the outer cylinder is connected with an inner cylinder through adjustable dampers and short springs. According to the leg type landing and buffering device, multiple shock isolation mechanisms are formed, so thatthe shock isolation efficiency is improved, and the leg type landing and buffering device can be repeatedly used, and is suitable for being used in landing and detection activities of planets such asthe earth, the moon, the mars and the minor planet.

Description

technical field [0001] The invention relates to a landing buffer device, in particular to a reusable leg-type landing buffer device. Background technique [0002] With the development of near-Earth and deep space exploration technology, landing devices usually need to carry payloads; however, due to the characteristics of unknown, changeable and strong impact of the landing environment, if effective protection is not carried out, the payload will inevitably be damaged. Therefore, the landing device needs to have strong environmental adaptability and be able to perform multi-directional shock isolation. [0003] In addition, some near-earth detection tasks (such as battlefield reconnaissance, etc.) are specific and non-repeatable, which requires the landing device to have high reliability, recyclability and reusability; thus reducing costs and improving the use of landing devices efficiency. The mechanical landing method has become the first choice for landing devices due t...
