Solar cell array unfolding device capable of being unfolded in large area

Abstract

The invention provides a solar cell array unfolding device capable of being unfolded in large area, belonging to the technical field of aerospace equipment and equipment. The solar cell array unfolding device mainly consists of a master plate unfolding part and a side plate unfolding part, and the side plate unfolding part is arranged on master plates; the master plate unfolding part consists of tripods, master plates, master plate connecting hinges and truss rod synchronizing mechanisms, the master plate connecting hinges drive each master plate to be unfolded in the shape of Z, and scissors-shaped mechanisms are jointly formed by the truss rod synchronizing mechanisms and the master plates, so that each master plate can be synchronously unfolded; and the side plate unfolding part consists of side plates, servo motors, driving systems, screw rods, four-bar mechanisms, linear guide ways and side plate slide ways, wherein the servo motors drive the screw rods at two sides by the driving systems, and push the side plates to slide by the four-bar mechanisms, so that the side plates can be unfolded. The side plates are additionally arranged on the master plates, so that the solar cell paving area is enlarged; and the two symmetrical four-bar mechanisms push the side plates to unfold, so that the device is simple in structure, and high in reliability, thereby being suitable for the spacecraft which has high-power requirement.

Description

technical field [0001] The invention relates to a large-area solar cell array deployment device, which is especially suitable for spacecraft with high power requirements, and belongs to the technical field of aerospace equipment and equipment. Background technique [0002] Solar arrays are the primary source of electrical power for most spacecraft. Rigid solar cell array is currently a mature solar cell array technology, and it is also the most widely used solar cell array on spacecraft. It usually includes a compression release mechanism, a deployment mechanism, a synchronization mechanism, a locking mechanism, and an orientation mechanism. The solar battery array is connected to the satellite body through the connecting frame; the compression release mechanism ensures that the battery array is in a safe retracted state during the launch process, and releases the solar battery array after the satellite reaches the predetermined orbit; the unfolding mechanism uses the solar ...

Problems solved by technology

[0003] The solar cell array currently used in my country is basically a rigid folding and unfolding type. This type of solar cell array has a simple structure, high packaging efficiency, good rigidity and high reliability; however, limited by the design of the structure, it is difficult to achieve a large The area of ​​solar cells is laid, and the power generation is small

With the increasingly complex functions of spacecraft, the energy demand of spacecraft is gradually increasing, which makes the power requirements for solar cell arrays of spacecraft also increase significantly. Rigid foldable solar cell arrays have certain limitations in this respect.
