Thick plate folding method, device and solar power generation device

Abstract

The invention relates to a thick plate folding method, a thick plate folding device and a solar power generation device. A thick plate comprises a folding base material and a thick plate material arranged on the folding base material; the method comprises the following steps: processing folds on the folding base material according to a miura-ori paper folding method, dividing the folding base material into N*M subunits by a plurality of folds, wherein N and M are both positive integers, and the thick plate material is located on the subunits; folding two adjacent parallel folds by taking the folds needing to holding the thickness of the thick plate at the periphery of each subunit as a center line, wherein the two adjacent parallel folds are both mountain lines or valley lines, and the distance between the two adjacent parallel folds is greater than the held thickness of the thick plate. According to the method, by the influence of folding one fold to be two parallel folds to hold thethickness in the folds, the defect that common application thickness cannot be smoothly folded is solved, a better engineering tolerance capacity is achieved, and the smoothness of the thick plate folding action and free folding and unfolding are realized.

Description

technical field [0001] The invention relates to the technical field of thick plate folding, in particular to a thick plate folding method, device and solar power generation device thereof. Background technique [0002] There are many structural applications in the state of the art, especially deployable structures, with the help of origami to build initial models. For example, solar sails that need to be deployed in space, solar power banks in personal consumer products, or deployable robotic structures. But origami has one of the biggest problems that bothers researchers is the thickness of origami. For example, when solar cells are folded, the thickness is a factor that must be considered. This is especially true when there are matrices in the fold structure, i.e. there are multiple layers of folds. [0003] Facing the technical problem of how to fold a thick plate, the existing method adopts increasing the thickness of the plate on the basis of the zero-thickness origa...

Problems solved by technology

However, the biggest defect of this model is that the above constraints are so strict that under this model, the angular distribution of each folded subunit and the position of the crease (or hinge) between each subunit must be precise. meet the requirements of the equation, otherwise the unfolding and retracting action will be difficult to carry out smoothly, and the model will not be able to accommodate the engineering margin

Therefore, unless high-precision machining and assembly are carried out, this model is difficult to realize in actual engineering

[0007] At the same time, according to Professor Chen Yan's model, the creases are often not on the same plane as the adjacent thick plates. This may be feasible for products that conform to connecting rod hinges, but it is difficult to achieve real engineering products that only have thick plates and creases.
