Embodiment Construction

[0034] The present invention will be further described below with reference to the accompanying drawings and specific examples.

[0035] A array of array folding antenna mechanism based on four-prism unit, such as figure 1 As shown, it includes N * N quadrolum unit, the tetra-prism unit composition structure, in the four-prism unit of 2 * 2 in the lateral direction and the longitudinal direction, the lower left side unit of the lower laterally arranged is the first four-prism The unit 1, the vertical arrangement of the vertical arrangement of the upper vertical arrangement is the second four-prism unit 2, and the right side of the lower laterally arranged right side unit is the third tetrapetial cone unit 3, and the upper vertical arrangement of the right side unit is the fourth four-prism unit 4. When the first four prism unit 1 is connected to the second tetrapetial cone unit 2, the first bottom flower disk 15 and the second bottom flower disk 16 are shared discs, and the first ...

Abstract

The invention discloses an array type folding and unfolding antenna mechanism based on a rectangular pyramid unit. The rectangular pyramid unit is composed of a top faceplate, a first bottom faceplate, a second bottom faceplate, a third bottom faceplate, a fourth bottom faceplate, four first bottom connecting rods, four second bottom connecting rods and four web members. According to the mechanism, a plurality of groups of tightly connected array type folding and unfolding antenna mechanisms are vertically and transversely combined in an array form, and every two top faceplates of the rectangular pyramid units after an array is formed are connected through a top end first connecting rod and a top end second connecting rod. According to the array type folding and unfolding antenna mechanism, by adding driving at a rotating pair, the faceplates are tightly leaned against one another, the shape of the faceplates is regular, and the faceplates are consistent in posture and are located in the same plane. The array type folding and unfolding antenna mechanism based on the rectangular pyramid unit has the comprehensive advantages of being high in rigidity, high in folding rate, high in supporting performance, adjustable in aperture size and the like.

Description

Technical field [0001] The present invention relates to the technical field of the discrete antenna mechanism, and in particular, a array of array-based fold antenna mechanism based on a four-prism unit. Background technique [0002] At present, the competition in the aerospace sector is more fierce, in order to transport various mechanical equipment to space in order to further carry out scientific research, the need for space-free institutions is an inevitable trend of future development. The space can be exhibited by the unique advantage of transportation, easy to transport, easy to install, and the quality of quality aerospace projects such as space rail construction and satellite communications are important. [0003] With the rapid development of space technology, higher requirements for high precision, large caliber, light massization, can have multiple basic units to achieve an adjustment and flexible transformation of antenna volume, quantity, and size. . The exhibible m...
