Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solar wings, and in particular to a novel space-expandable solar wing. Background Art
[0002] Solar panels, also known as solar arrays, are key components on spacecraft used to collect solar energy and convert it into electricity. They typically consist of multiple solar panels that need to be folded up during launch to fit within the limited space of a rocket and unfolded once in space to maximize solar energy collection.
[0003] Early solar wing designs were relatively simple, often employing fixed or semi-fixed structures, which limited their adaptability to different orbits and missions. As technology evolved, solar wing designs became more complex, incorporating multiple folding and unfolding mechanisms to ensure compactness during launch and efficient energy collection in orbit.
[0004] However, existing technologies such as CN115610709B, although they disclose a foldable and retractable solar wing mechanism, all of their solar wings adopt a linear folding method, which has low folding efficiency and occupies a large space; in addition, all folding hinges adopt a parallel structure, lack anti-torsion support, and have problems such as insufficient stability after unfolding. Summary of the Invention
[0005] The purpose of this utility model is to overcome the above problems and provide a new type of space-expandable solar wing. To achieve the above purpose, this utility model adopts the following technical solutions:
[0006] A novel space-expandable solar wing is composed of multiple folding units hinged to each other; each folding unit includes a central plate, a folding plate, and an outer plate from the middle to the sides, and the ends of the folding plate are hinged to the central plate and the outer plate respectively;
[0007] A folding mechanism is provided between adjacent folding units, and a locking mechanism is provided on the folding mechanism; the folding mechanisms on the solar wings are arranged in a bow shape.
[0008] As an improvement, the hinge between the folding plate and the center plate is located at the top of the folding plate on the side close to the center plate;
[0009] The hinge between the folding plate and the outer plate is arranged at the bottom of the folding plate close to the outer plate.
[0010] As an improvement, the folding plate is the same size as the outer plate, and the length of the central plate is greater than or equal to twice that of the outer plate.
[0011] As an improvement, the folding mechanism includes a first folding mechanism and a second folding mechanism; the first folding mechanism is arranged between outer plates of adjacent folding units, and the second folding mechanism is arranged between central plates of adjacent folding units;
[0012] The first folding mechanism and the second folding mechanism are arranged at intervals.
[0013] As an improvement, the folding mechanism adopts a large-span hinge structure, including two mutually hinged fixed plates, and the two fixed plates are respectively fixedly connected to the adjacent central plate, folding plate or outer plate;
[0014] The fixed plate includes a long plate with a large span and a short plate with a large span.
[0015] As an improvement, the locking mechanism is provided near the folding mechanism, and the locking mechanism comprises two opposite fixing parts, which are respectively provided on adjacent central plates, folding plates or outer plates;
[0016] One of the fixing parts is provided with a spring and a lock tongue, and the other fixing part is provided with a socket for the lock tongue to be inserted and locked.
[0017] The advantages of the present invention are:
[0018] 1. By designing multiple hinged folding units and optimizing the hinge locations of the folding panels with the center and outer panels, this utility model improves the folding efficiency of the solar panels and reduces the space they occupy during launch. Due to the compact design of the folding units, the solar panels occupy less space when folded, facilitating the deployment of more solar panels within limited rocket space or freeing up space for other equipment.
[0019] 2. The folding mechanisms on the solar wing of this utility model are arranged in a bow shape, with the hinges within the folding units perpendicular to their length, and the hinges between the folding units parallel to their length. This bow-shaped arrangement of the folding mechanisms and the perpendicular hinges effectively improve the stability and torsional resistance of the solar wing, effectively enhancing the structural stability of the solar wing after deployment and reducing vibration and deformation that may be encountered in a space environment.
