Problems solved by technology

[0003] Chinese patent 201410055607.X discloses a ring-shaped truss-type large-scale space folding mechanism, which is driven by ropes or springs, and the stability of the mechanism is low; It can only be folded on a plane, and the folding is relatively small; Chinese patent 201210072572.1 discloses a scissors-based quadrilateral unit planar array folding mechanism. The spatial folding process of this mechanism is complicated. When the folding mechanism enters the space track, the mechanism unfolds into a predetermined structure more difficult form
[0004] At present, there is no invention and design of a space folding mechanism that has the characteristics of light weight, large folding ratio, high precision, high rigidity, high strength, high stability, and small movement impact, and the space folding process is simple.

Abstract

The invention discloses a folding and unfolding mechanism with two slider and spring combined and restricted telescopic rods. The folding and unfolding mechanism comprises an octagonal support, three-degree-of-freedom hinges and foldable units, wherein the octagonal support is fixedly connected with the three-degree-of-freedom hinges; the foldable unit comprises an inclined side rod, a first gasket, two slider and spring combined and restricted telescopic rods and a second gasket; the octagonal support is connected with the foldable units through the three-degree-of-freedom hinges; and the inclined side rod, the slider and spring combined and restricted telescopic rods and the gaskets are connected through revolute pairs. Through folding twice, the space folding of the mechanism can be realized, and the folding ratio is large; and moreover, the mechanism has the characteristics of light weight, high precision, high rigidity and high strength, can be applied to the fields of space exploration, earth observation and mobile communication, and is extremely high in adaptability and practicability.

Description

technical field [0001] The invention relates to a folding mechanism, in particular to a folding mechanism in which double slider springs combine to constrain a telescopic rod. Background technique [0002] With the development of the aerospace industry, in order to meet the needs of different space missions, more and more space folding mechanisms are used in space missions such as space stations, mobile communications, earth observation and planetary exploration. However, due to the limitation of the volume of the launch vehicle, the folding mechanism is required to have light weight, large folding ratio and high stability during the launch process. After the folding mechanism enters the space orbit, it can be unfolded into a predetermined structural form. [0003] Chinese patent 201410055607.X discloses a ring-shaped truss-type large-scale space folding mechanism, which is driven by ropes or springs, and the stability of the mechanism is low; It can only be folded on a pla...
