Embodiment Construction

[0048] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0049] refer to Figure 1 to Figure 7 , this embodiment provides a memory alloy planetary exploration lander based on a negative Poisson's ratio structure, including a lander body 9 and a buffer structure 1 .

[0050] The main body 9 of the lander is a cylindrical structure with a closed bottom, and its interior is used to accommodate payloads (including scientific instruments such as cameras and communication antennas).

[0051]The buffer structures 1 are connected to the side wall of the main body 9 of the lander at equal intervals in the circumferential direction.

[0052] The buffer structure 1 includes: a mechanical leg assembly 2 , a main shock absorber 5 and a foot pad 4 .

[0053] The mechanical leg assembly 2 includes a landing leg 21, which is a mem...

Abstract

The invention relates to a memory alloy planet detection lander based on a negative poisson ratio structure. The memory alloy planet detection lander comprises a lander body and a buffer structure. The lander body is used for containing effective loads, and the buffer structures are connected with the side wall of the lander body at equal intervals in the circumferential direction. The buffer structure comprises a mechanical leg assembly, a main shock absorber and a foot pad. The mechanical leg assembly comprises a landing leg which is made of memory alloy of a negative poisson ratio structure. One end of the main shock absorber is connected with the lander body, and the other end of the main shock absorber is hinged to the spherical hinge at the upper end of the landing leg to form a revolute pair of the main shock absorber relative to the mechanical leg assembly. The memory alloy planet detection lander has the beneficial effects that through the memory alloy landing supporting leg of the negative poisson ratio structure and the revolute pair of the main shock absorber relative to the mechanical leg assembly, the planet detection lander has high landing buffer performance, attitude control capacity and shape restorability, and after the buffer performance and attitude control capacity are enhanced, the lander can carry heavy loads.

Description

technical field [0001] The invention relates to a planetary detection lander, in particular to a memory alloy planetary detection lander based on a negative Poisson's ratio structure. Background technique [0002] With the development of science and technology, human beings have started continuous exploration activities of extraterrestrial planets. Through the detection of extraterrestrial planets, human beings can not only discover precious mineral deposits on the planets by observing the geological structure, surface shape, and surrounding environment of the planets and their satellites, laying the foundation for future resource mining, but also through the analysis of the chemical elements on the planets. Conduct sampling analysis to understand the origin, evolution and current status of galaxies, and explore the origin of life. [0003] At present, the known landing methods of landers are mainly divided into two types: "hard landing" and "soft landing". "Hard landing" ...
