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 hinge with a seamless folding mechanism in a tubular structure, which includes a fixed arm, a transmission shaft, an engaging block, a bevel gear, an elongated screw, a slider, a rotating arm, a bearing, a preload spring, a transmission arm, an actuating Rods, slide rails and guide slip rings, the fixed arm and the driving arm are embedded in the front end of a tubular structure, the rotating arm is embedded in the rear end of another tubular structure, and the rotating arm and the driving arm are connected by a shaft; the thin filament The rod and the transmission shaft are respectively located in the inner cavity of the transmission arm and the fixed arm; the two ends of the slender lead screw and one end of the transmission shaft are fixedly connected with the bearing and placed in the center of the inner cavity, which can transmit kinetic energy and convert the rotational motion into a straight line sports. The present invention adopts the dual drive mode of the ratchet mechanism and the gear mechanism, which improves the reliability of the hinge extension of the mechanism, and can be automatically extended under the drive of the motor to form an ultra-long and stable unfolded structure.
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...
