specific Embodiment approach 1

[0012] Specific implementation mode one: as Figure 1~3 As shown, the low-impact unfolding hinge based on the resistance spring of this embodiment includes a breakaway sleeve 1, an inner ring 2, a resistance spring 3, an outer ring 4, a bottom ring 5, a positioning sleeve 6, a male hinge 8, and a scroll spring 9 , spring fixed bushing 11, female hinge 12, outer rod gasket 13, stud 14, hinge central shaft 15, two spring snap rings 10 and two spring fixed bushings 11; the male hinge 8 is provided with two supports seat, the hinge center shaft 15 is fixedly installed on the two support seats of the male hinge 8, the upper part of the female hinge 12 is installed on the hinge center shaft 15 and the upper part of the female hinge 12 is located between the two support seats of the male hinge 8, and the screw The column 14 is mounted on the upper part of the female hinge 12, the stud 14 is arranged parallel to the hinge central axis 15, and the two spring fixed bushings 11 are set o...

specific Embodiment approach 2

[0018] Specific implementation mode two: as figure 2 and image 3 As shown, the resistance spring 3 in this embodiment is a scroll spring. In such a design, since the driving source is the scroll spring 9, when the resistance spring 3 is designed as a scroll spring, the torque of the driving source can directly act on the resistance spring 3, and no other mechanism is needed to convert the torque, which is convenient for direct storage of energy. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0019] Specific implementation mode three: as image 3 As shown, in this embodiment, the two protrusions on the outer ring 4 are evenly distributed along the circumferential direction, and the two grooves on the detachment sleeve 1 are evenly distributed along the circumferential direction. In such a design, the two protrusions on the outer ring 4 slide simultaneously in the two grooves of the disengagement sleeve 1, so that the disengagement sleeve 1 is stressed symmetrically, and the frictional self-locking of the disengagement sleeve 1 in the axial direction is avoided due to excessive pressure. . Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a low-impact expandable hinge, and discloses a low-impact expandable hinge based on a resistance spring. The low-impact expandable hinge solves the problem that an expandable hinge is locked and impacted because the expandable tail end of a solar wing expandable hinge driven by a volute spiral spring produces a very large expandable angular velocity in the prior art. An outer ring is arranged on a hinge center shaft in a sleeving manner and is adjacent to a bottom ring; a protrusion is formed on an inner hole, opposite to the outer ring, of the bottom ring; a spiral groove is formed in the surface, opposite to the bottom ring, of the outer ring; the protrusion on the bottom ring is in sliding fit with the spiral groove in the outer ring; two lugs are arranged on the other end surface of the outer ring; a separate sleeve is arranged on the hinge center shaft in the sleeving manner, and two grooves matched with the two lugs are formed in one end of the separate sleeve; an inner ring is arranged on the hinge center shaft in the sleeving manner and positioned in the outer ring; and the resistance spring is arranged at the other end of the separate sleeve, the inner ring of the resistance spring is fixed at the other end of the separate sleeve, and the outer end of the resistance spring is connected with a spring fixing shaft sleeve at the other end of a stud. The low-impact expandable hinge is applied to a space expandable mechanism.

Description

technical field [0001] The invention relates to an unfolding hinge based on a resistance spring, in particular to a low-impact unfolding hinge based on a resistance spring. Background technique [0002] The unfolding hinge is widely used in space expandable mechanisms because it has the functions of hinge, unfolding, and locking at the same time. These mechanisms generally have the characteristics of large size, light weight, and are difficult to attenuate once they are excited. Shock, to prevent the components from resonating and causing damage or affecting the working state. [0003] At present, the deployment end of the solar wing deployment hinge driven by the scroll spring will generate a large deployment angular velocity, which will cause the locking impact of the deployment hinge. Contents of the invention [0004] In order to solve the problem that the deployment end of the solar wing deployment hinge driven by scroll springs generates a large deployment angular v...
