Abstract

A rocker landing ladder of a planet exploration vehicle used for releasing relates to a landing ladder which solves the problems that the existing landing ladder has a large size after being expanded and forms a connection inclined plane between a lander and the surface of the planet, and the inclined plane is not beneficial to the stable releasing of the exploration vehicle after being expanded. A transmission mechanism (31) is arranged below a car loading platform (15); a second chain / belt wheel (12) is fixedly arranged at one end of the lower end surface of the car loading platform (15); a first chain / belt wheel (6) and the second chain / belt wheel (12) are connected by a transmission chain / belt (18); the upper end of a main rocker (4) is articulated with the two ends of a driven shaft (32); the lower end of the main rocker (4) is arranged on a drive shaft (19) by a bearing; the output shaft of a drive motor (1) is fixedly connected with the central wheel of a harmonic reducer (2); the flexible wheel of the harmonic reducer (2) is fixedly connected with one end of the drive shaft (19). The landing ladder of the invention after being expanded forms a connection horizontal level between the lander and the surface of the planet to realize the stable releasing of the exploration vehicle.

Description

technical field [0001] The invention relates to a landing ladder, in particular to a rocker-arm type landing ladder used for releasing a planetary exploration vehicle. Background technique [0002] When a legged landing probe is used for planetary exploration, the planetary exploration vehicle is often carried on the upper or middle part of the landing probe, and there is a certain distance from the surface of the planet. It is necessary to use a landing ladder to release the planetary exploration vehicle to the surface of the planet. The configuration and structural design of the landing ladder need to meet the technical requirements of light weight, simple structure, small footprint, high working reliability, stable release process, and the vehicle-carrying platform parallel to the surface of the planet as much as possible during the release process. Most of the existing foreign landing ladders use telescopic or rotary hinge folding structures. After unfolding, a connectin...
