Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] like figure 1 and figure 2 As shown, the structure skeleton of the sliding type expandable umbrella-shaped antenna of the present invention is composed of a base 1, a pin 9, a primary rod 2, a secondary rod 3, a gear 4, a pull cord 5, a connecting rod 6, a nut 7 and a lead screw 8. ; The base 1 is connected to the bottom ends of multiple radial first-stage rods 2 in the circumferential direction through pins 9; the second-stage rod 3 is set in the top groove of the first-stage rod 2; 2 The gear 4 at the top meshes; the shaft of the gear 4 is wound with a pull rope 5, and the pull rope 5 passes through the round hole of the base 1 along the outside of the first-stage rod to connect to the driving device at the bottom of the antenna structure skeleton; the lower part of the first-stage rod 2 passes through the connecting rod 6...

A sliding-type expandable umbrella-shaped antenna structure skeleton and a deployment method, the umbrella-shaped antenna structure skeleton is composed of a base, pins, a first-stage rod, a second-stage rod, gears, pull ropes, connecting rods, nuts, and lead screws; It is connected with the bottom end of the first-stage rod through pins; the second-stage rod is set in the groove at the top of the first-stage rod; there is an external gear on the outside of the second-stage rod, which meshes with the gear at the top of the first-stage rod; The first-stage rod passes through the round hole of the base to connect the driving equipment at the bottom of the antenna structure skeleton; the lower part of the first-stage rod is connected to the nut through the connecting rod in the circumferential direction, and the nut is installed on the lead screw to form a lead screw nut structure; the lead screw drives the nut upwards Move, the framework of the umbrella-shaped antenna structure is folded; the lead screw drives the nut to move downward, and the framework of the umbrella-shaped antenna structure opens the first-stage rod; the driving device tightens the pull cord to drive the second-stage rod to slide out; in this way, the framework of the umbrella-shaped antenna structure is unfolded. The framework of the umbrella-shaped antenna structure of the present invention has the characteristics of small folded size, large unfolded size, repeated retractable, light and handy structure, and high reliability.
Description
technical field [0001] The invention relates to the technical field of deployable antennas, in particular to a structural frame and a deploying method of a slide-type deployable umbrella-shaped antenna. Background technique [0002] The deployable umbrella antenna is a deployable antenna with a relatively simple structure. It is mainly composed of radial rigid ribs and reflective surfaces. It is named for its unfolding and folding similar to umbrellas in daily life. The expandable umbrella-shaped antenna makes the radial rib into a certain curve shape, the reflective net is fixed on the front of the radial rib that can rotate around the pivot, and the adjustment net is located on the back of the radial rib. The adjustment of the cable ensures that the reflective mesh can accurately achieve the desired curved surface shape in the unfolded state. [0003] The expandable umbrella antenna has the advantages of simple structure, easy to fold and unfold, and high reliability, so ...
