Abstract

The invention relates to a three-leg type lander buffer mechanism. The three-leg type lander buffer mechanism comprises a working platform, a cabin fixedly connected to the lower end of the working platform, three leg pads which are arranged symmetrically below the cabin, three identical main landing legs which are connected between the working platform and the leg pads symmetrically, and six identical auxiliary landing legs which are symmetrically connected between the cabin and the leg pads. Each main landing leg comprises a first rod and a second rod, wherein the first rod and the second rod are connected from top to bottom, and are connected through a first prismatic pair. Each auxiliary landing leg comprises a third leg and a fourth leg, wherein the third leg and the four leg are connected from top to bottom, and are connected through a second prismatic pair. The three-leg type lander buffer mechanism has the advantages that the multi-dimensional buffer function can be achieved when a lander is landing, and the shock borne by the working platform is reduced; the working platform of the mechanism has the dual-rotation one-translation motion output function so that the working platform can be adjusted to be stable; the three-leg type lander buffer mechanism is compact in structure, easy to control and applicable to the place with a complicated landing site and a wide impact frequency range.

Description

technical field [0001] The invention relates to a buffer mechanism of a three-legged lander. Background technique [0002] In the deep space exploration activities of human beings, it is necessary to safely launch the detection equipment to the target star, and the lander is the carrier of these detection equipment, and it is also the key to ensure its safe landing. The structure of the cantilever-legged lander is currently commonly used. It has the advantages of stable landing attitude, high reliability, easy control, and retractability, and is more suitable for complex landing sites. Attitude stability, and it is difficult to buffer multi-dimensional impact. [0003] The parallel mechanism is usually composed of a dynamic platform, a static platform and several branch chains between the two platforms. It has the advantages of high rigidity, fast speed and high precision. It is widely used in industrial robots, motion simulators, parallel machine tools and other fields. I...
