Abstract

The invention provides a space unfolding device based on elastic potential energy. The device comprises an elastic piece, a male hinge and a female hinge, wherein one end of the male hinge is connected to a first connected body and is provided with a locating pin on the top; one end of the female hinge is connected to a second connected body while the other end of the female hinge is connected to the other end of the male hinge, and a locating hole matched with the locating pin is formed in the top of the female hinge. The invention further provides an unfolding and folding method of the space unfolding device. The method comprises the steps of: when the space expanding device expands, the bent state of the elastic piece is turned into a straight state, wherein the first connected body and the second connected body are located in a same plane; when the space unfolding device is folded, the elastic piece is folded to be turned into the bent state from the straight state, wherein the first connected piece and the second connected piece are unfolded and located. The space unfolding device based on elastic potential energy provided by the invention is simple in structure, reliable in property and relatively light in weight, and can effectively reduce the specific gravity of the unfolding device in a super-size effective load.

Description

technical field [0001] The invention relates to the technical field of space exploration, in particular to a space deployment device based on elastic potential energy and a method for deploying and retracting the same. Background technique [0002] At present, the demand for super-large spacecraft and its components is increasingly obvious, such as antennas with a diameter of hundreds of meters, solar sails of several square kilometers, battery arrays, etc. When launching such payloads, they are all in a folded state. The unfolding device realizes the unfolding lock. The folding and unfolding of this type of oversized unfolded structure will use a large number of unfolding devices. The deployment device is a relatively complex spacecraft mechanism, which is generally used in conjunction with the release device and the locking device. The deployment device is in a folded and compressed state during launch. After the spacecraft reaches the predetermined orbit, the release d...
