Embodiment Construction
[0029] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0030] The carrier of the seamless folding mechanism hinge of the tubular structure of the present invention is a tubular expandable mechanism, such as a whip antenna, a folding screw, a space extension arm and other tubular mechanisms.
[0031] Such as Figure 1-Figure 3 As shown, the seamless folding mechanism hinge of tubular structure includes a fixed arm 1, a transmission shaft 2, an engaging block 3, a bevel gear 4, a slender screw 5, a slider 6, a rotating arm 7, a bearing 9, and a preload spring 10 , transmission arm 11, actuating rod 12, slide rail 13, guide slip ring 14; the tubular structure has a large volume, adopts lightweight materials and has good rigidity, and the fixed arm 1 and the transmission arm 11 are closely embedded in the inner side of the front end of a tubular structure. , the rotating arm 7 is fixed inside the rear ...

The invention relates to a seamless folding and unfolding mechanism hinge of a tubular structure. The seamless folding and unfolding mechanism hinge of the tubular structure comprises a fixed arm, a transmission shaft, meshing blocks, a bevel gear, a slender lead screw, a slider, a rotating arm, a bearing, a pre-tightening spring, a transmission arm, an actuating rod, a sliding rail and a guide sliding ring; the fixed arm and the transmission arm, closely adjacent to each other, are embedded into the inner side of the front end of a tubular structure, and the rotating arm is embedded into theinner side of the back end of the other tubular structure and is connected with the transmission arm through a rotating shaft; the slender lead screw and the transmission shaft are positioned in innercavities of the transmission arm and the fixed arm respectively; and the two ends of the slender lead screw and one end of the transmission shaft are fixedly connected with the bearing and arranged in the center of the inner cavity, so that kinetic energy can be transmitted, and rotating motion is converted into linear motion. By adopting a dual-drive mode of a ratchet mechanism and a gear mechanism and improving the reliability of stretching of a mechanism hinge, the seamless folding and unfolding mechanism hinge of the tubular structure can perform automatic stretching under the driven of amotor, and an ultra-long stable unfolding structure is formed.
Description
technical field [0001] The invention relates to a seamless folding mechanism hinge of a tubular structure, which is applied in the docking of tubular expandable mechanisms and belongs to the technical field of mechanisms. Background technique [0002] The hinge of the seamless folding mechanism of the tubular structure is an important part of the tubular expandable mechanism, which directly affects the deployment of the expandable mechanism. The hinge of the seamless folding mechanism of the tubular structure is to realize the seamless docking of the tubular structure under the driving action, and can complete the extension of multiple tubular structures at the same time. It is suitable for tubular structures such as whip antennas, folding screws, and space extension arms. middle. However, the hinge of the existing folding mechanism cannot realize seamless docking. Contents of the invention [0003] The technical solution of the present invention: the purpose of the pres...
