Abstract

The invention relates to a space foldable mechanism, in particular to a space foldable mechanism derived from five-revolute-pair units, aiming at solving the problem that a high-storage-ratio space foldable mechanism is not developed at present. The scheme one is that a first connecting rod is rotatably connected with a first revolute pair, the first connecting rod is connected with a second connecting rod, the second connecting rod is connected with a third connecting rod and the third connecting rod is connected with a fourth connecting rod. The scheme two is that three foldable units are arranged in the shape of a triangular closed loop. The scheme three is that six space modules are sequentially connected to form a closed loop structure. The scheme four is that a first five-revolute-pair unit is connected with a second five-revolute-pair unit, the second five-revolute-pair unit is connected with a third five-revolute-pair unit and the third five-revolute-pair unit is connected with the first five-revolute-pair unit. The scheme five is that a first umbrella-shaped module is connected with a second umbrella-shaped module, the second umbrella-shaped module is connected with a third umbrella-shaped module and the third umbrella-shaped module is connected with the first umbrella-shaped module. The space foldable mechanism derived from the five-revolute-pair units is used for spacecrafts.

Description

technical field [0001] The invention relates to a space foldable mechanism. Background technique [0002] With the increasingly complex functions of spacecraft, the energy demand for spacecraft has increased significantly, and the area of ​​solar battery arrays on spacecraft has also increased significantly. For complex and large spacecraft such as the International Space Station, the area of ​​solar battery arrays Huge, but the envelope size of the spacecraft is limited by the volume of the payload compartment of the launch vehicle, which requires a high folding ratio that can shrink to a small volume during the launch phase and expand to a large area or volume during the operation phase. exhibition organization. Deployable mechanisms are widely used in spacecraft such as space stations, communication satellite platforms, space telescopes, space shuttles, and planetary probes. Such as the basic skeleton of the space station, the expandable / collapsible space manipulator, t...
