摘要

Landing on surface of planet is the most direct and effective means of deep space exploration. Taking the picture of lander and surrounding environment can monitor the working status of the lander, and different exploration tasks arranged different imaging methods. Apollo 11 achieved manned lunar landing, so astronauts leaved lunar lander and installed imaging camera; Curiosity rover is equipped MAHLI (Mars Hand Lens Imager) at the end of the robot arm, and capture the own image of the rover; Chang'E-3 consists of lander and rover, which can captured image each other. In this paper, taking into account the working conditions without rover, we designed an ejection-style self-imaging apparatus for lunar lander, which consists of the optical imaging system, the tumbler structure body and the ejector body. Ejector body is mounted on the lunar lander to eject the imaging system to the appropriate distance. To make the image of lander in the center field of view, the imaging system needs to be installed on a tumbler structure body to ensure that the optical axis of imaging system can be adjusted to the direction toward the lander. We designed and developed the imaging optical system, the mechanical structure of tumbler body and ejector body, deduced reasonable compression spiral spring parameter according to the application requirements, and completed finite element analysis of tumbler structure body in the fall process. The experiments on the sand, soil and gravel ground verify the feasibility of the design scheme.
