Embodiment Construction

[0018] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings:

[0019] A movable structure based on a folding rod scissor unit, such as Figure 4 As shown in the figure, it is composed of a link mechanism and a cable. The link mechanism has 9 folding rod scissor units connected with the adjacent folding rod scissor units through its upper node 1 and lower node 2, wherein The middle pin joint node 3 of the two folding rod scissor units at the head and tail is rotatably connected with the support,

[0020] Replace any one of the fifth folding-bar scissor units with a four-bar hinged unit 4. The four-bar hinged unit, such as Figure 5 As shown, the pinned node in the middle of the folding rod scissor unit is changed to a hinged node, that is, four rods are connected at the same node, and each rod can rotate around the middle hinged node, so that the connection formed The lever mechanism has two degre...

Abstract

The invention discloses a movable structure based on a folding-rod shearing-type unit, composed of a connecting bar mechanism and inhaul cables, wherein the connecting bar mechanism comprises two sub connecting bar mechanisms; a connecting bar is hinged with four joints between the two sub connecting bars respectively; the other ends of the four connecting bars are hinged together to form a hinging joint; a middle pin joint of the first folding-rod shearing-type unit of the first sub connecting bar mechanism is rotatably connected with a bracket; a middle pin joint of the tail folding-rod shearing-type unit of the second sub connecting bar mechanism is rotatably connected with a bracket; thus, the geometrical shape of the structure can be changed by change of the length of four inhaul cables. The invention is a connecting bar mechanism composed of a folding-rod shearing-type unit and a multi-rod hinging unit, and uses four inhaul cables to drive the connecting bar mechanism so as to form structures with a plurality of stable geometrical shapes; the geometrical shapes of the movable structure can be expressed by two arcs; and the structure is rational and the design and construction are simple, so that the movable structure is suitable for buildings with different spans.

Description

technical field [0001] The present invention relates to a movable structure, in particular to a movable structure based on a folding rod scissor unit. Background technique [0002] Since the Spanish architect Pinero first successfully applied the concept of deployable structures to the design of "movable theaters" in the 1960s, the application of openable roofs in large-span space structures has rapidly increased. On the other hand, with the acceleration of people's exploration of outer space, deployable structures have received extensive attention, and related research results have been applied to solar panels and satellite antennas in space. The most widely used currently is the deployable structure based on scissor like element. From a geometrical point of view, the basic principle of this type of deployable structure is that each pair of connecting rods is connected by a column hinge, and each pair of connecting rods can only rotate relative to the axis that is perpendi...
