Single driving multi-stage synchronous stretch-retract repeatable solar panel unfolding mechanism

Abstract

Disclosed is a single driving multi-stage synchronous stretch-retract repeatable solar panel unfolding mechanism. The solar panel unfolding mechanism comprises a machine frame, a motor, a speed reducer, a speed accelerator, large and small steel wire rope wheel set components, steel wire ropes and two-stage solar panels, wherein the machine frame is fixed on the ground, the motor, the speed reducer, a coupling and the speed accelerator are in series connection, the speed reducer and the speed accelerator are fixed on the machine frame, the small steel wire rope wheel set component is fixed on one end of one side of a first stage solar panel, and the other end of the same side of the first stage solar panel is connected with the machine frame through a first hinge; two ends of the other side of the first solar panel are connected with the second solar panel through a second hinge and a third hinge respectively; the large steel wire rope wheel set component is arranged between the two-stage solar panels and the steel wire ropes are connected with the large steel wire wheel set component and the small steel wire rope wheel set component. The single driving multi-stage synchronous stretch-retract repeatable solar panel unfolding mechanism has the advantages of being simple in structure, low in cost, strong in reliability, low in failure rate and long in service life; meanwhile, the mechanism is capable of effectively unloading a radial tensile force exerted on a driving shaft during a driving process, can prevent the driving shaft from bending or deforming, thus increasing transmission precision.

Description

technical field [0001] The invention relates to a solar sail panel deployment mechanism for a lunar vehicle. [0002] technical background [0003] The lunar rover's solar sail panel deployment mechanism is an important part of the lunar rover's energy acquisition system, and it is also one of the most important expandable accessories of the lunar rover. Due to its special working environment, it has the basic requirements of low power consumption, small mass, simple structure, flexible rotation and convenient control. At present, the multi-stage repeatable deployable solar panel deployment mechanisms are all active deployment mechanisms, usually driven by electricity. [0004] In our country, the research on the active deployment mechanism of solar panels for lunar vehicles is mainly concentrated in major universities: [0005] Among them, Harbin Institute of Technology has designed a solar wing deployment mechanism for lunar vehicles with repeatable folding function. This...
