Solar battery sailboard unfolding mechanism

Abstract

The invention discloses a solar battery sailboard unfolding mechanism, and can be used for solving the problems that a pneumatic drive is adopted for the existing solar battery sailboard unfolding mechanism, the sealability requirement is high, the structure is complicate, and floor space is large. The unfolding mechanism comprises a fixed support and a moveable support and a folded arm mechanism, wherein multiple groups of folded arm mechanisms are articulated between the fixed support and the moveable support, and the two ends of the fixed support are respectively articulated with two unfolding inner arms; the two ends of the moveable support are respectively articulated with two unfolding outer arms, the other ends of the unfolding outer arms and the unfolding inner arm are provided with gears so as to form gear pairs which are mutually meshed; and a hydraumatic push-pull rod is arranged between the fixed support and the unfolding inner arms, and the gear pairs positioned on one side of the two ends of the fixed support are connected through a stretching mechanism. The unfolding mechanism provided by the invention has the advantages that the constructional element quantity is less, developed area is large, the floor area is small after shrinkage, the unfolding mechanism has hardly any requirements on sealability and the like, the hydraulic drive is adopted, and the reliability is high.

Description

technical field [0001] The invention relates to a solar cell sail panel unfolding mechanism. Background technique [0002] The power generation of solar panels is proportional to the area and number of solar panels. The larger the number, the greater the power generation, but the number is limited by the space. Therefore, how to make the solar panels large in area after deployment and small in volume after retraction, This is a problem that the industry has been urgently waiting to solve. [0003] Chinese patent CN200810137379.5 discloses a solar battery sail panel deployment mechanism, which adopts multiple pairs of gear transmission and pneumatic drive, resulting in increased manufacturing costs and higher requirements for sealing, which virtually increases the cost, and it cannot be automatically retracted after inflation and expansion, requiring external force, and can only be expanded in a straight line, and the expansion area is limited.
