Problems solved by technology
[0003] In order to solve the above-mentioned problems in the prior art, the present invention designs a movable lunar surface soft landing device. Each foot of the device adopts a set of main buffer telescopic mechanisms and two sets of auxiliary buffer telescopic mechanisms to form a three-degree-of-freedom parallel The walkable buffer mechanism can improve the landing stability of the mechanism and solve the defect of insufficient mobility of the soft landing mechanism in the prior art. At the same time, through the combination of the design of the swinging calf mechanism, the attitude adjustment after landing can be realized

The invention discloses a movable lunar surface soft landing device, which belongs to the field of aerospace machinery. The device of the present invention is composed of several three-degree-of-freedom parallel movable buffer mechanisms, each three-degree-of-freedom parallel movable buffer mechanism includes a set of main buffer telescopic mechanisms and two sets of auxiliary buffer telescopic mechanisms, and the main buffer telescopic mechanism and auxiliary The buffer telescopic mechanism has both buffer and telescopic functions. A three-degree-of-freedom parallel travelable buffer mechanism is composed of the main buffer telescopic mechanism and the auxiliary buffer telescopic mechanism. The parts of the device are connected by hinges, and the movement of the entire device has flexibility and landing reliability. The device of the present invention realizes the tension-compression buffer performance of the structure when the auxiliary buffer mechanism of the lander is subjected to tension or pressure, and also realizes the walkable function of the whole machine; the structure design of the device of the present invention is reasonable, the performance is reliable, and the Structural design requirements for the integration of landing buffer and walking.
Description
technical field [0001] The invention relates to a movable lunar surface soft landing device, which belongs to the field of aerospace machinery. Background technique [0002] In the future detection missions of the moon and other extraterrestrial bodies, the probe is required to have certain attitude adjustment and movement capabilities after a soft landing, so as to enhance the adaptability to different detection tasks and expand the scope of the detection area. Since the currently known soft landing devices only have a certain landing stability, but are not maneuverable enough to achieve attitude adjustment and movement, the entire device cannot move flexibly, and the walkability of the whole structure is poor. Or the multi-point detection capability of the surface environment of other alien bodies is not good. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention designs a movable lunar surface soft lan...
