specific Embodiment approach 2

[0016] Specific implementation mode two: combination figure 1 and figure 2 The present embodiment will be described. The number of hemispherical protrusions 13 - 1 in the present embodiment is 10 to 20 pieces. If the number of hemispherical protrusions 13-1 is within the above range, the frequency of the small reed 2-1 can be increased to increase the resistance during the unfolding process of the hinge, thereby reducing the angular velocity at the unfolding end of the hinge. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0017] Specific implementation mode three: combination figure 1 and figure 2 This embodiment will be described. The number of hemispherical projections 13 - 1 in this embodiment is twelve. Such setting can increase the frequency of the small reed 2-1, so as to increase the resistance during the unfolding process of the hinge, thereby reducing the angular velocity at the unfolding end of the hinge. Other components and connections are the same as those in the second embodiment.

Abstract

The invention provides a deceleration component for reducing the locking impact of an unfolded hinge, and aims at solving the problems that the unfolded hinge is driven by a volute spiral spring, great unfolding angle speed can be generated at the tail end, and great locking impact of the unfolded hinge can be caused. A male hinge is arranged on a center shaft, a female hinge is fixedly arranged on a hinge sleeve, the inner end of the volute spiral spring is fixedly arranged on a spring inner pile, the outer end of the volute spiral spring is inserted into a long groove formed in a spring fixing shaft sleeve, a stud passes through the female hinge, one end of a transfer joint is fixedly arranged on a transfer sleeve and a gearwheel shaft, the other end of the transfer joint is fixedly arranged on a transfer joint sleeve, the gearwheel shaft and the transfer joint are fixed through a pin shaft, a gearwheel is fixedly arranged on the gearwheel shaft, wheel teeth are engaged with the gearwheel, a pinion shaft is supported in a top plate, a rotating drum is fixedly arranged at the upper end of the pinion shaft, a plurality of hemispherical bulges are uniformly distributed on the outer surface of the rotating drum in the same circumference, a small reed arranged on a reed plate is arranged right against the hemispherical bulges, the reed plate is fixedly arranged on the top plate through a connecting element, and the top plate and the male hinge are respectively connected with a vertical plate. The deceleration component is used on spacecraft unfolding mechanisms.

Description

technical field [0001] The invention relates to a component used on an unfolding hinge, in particular to a deceleration component for reducing the locking impact of the unfolding hinge. 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. Avoid impact as much as possible to prevent damage to components caused by resonance or affect working conditions. [0003] The unfolding hinge is a hinge mechanism widely used in space unfolding mechanisms. It is mainly used to connect rigid parts (such as solar panels and satellite antennas) and complete the unfolding action. After the unfolding action is completed, the unfolding hinge can lock itself. The unfolding hinge is usually mainly composed of the following components: drive s...
