Abstract

The invention discloses an unfolding hinge speed reduction mechanism based on a spring and a connecting rod mechanism, and relates to the unfolding hinge speed reduction mechanism. The mechanism solves the problems that at present, the unfolded tail end of an unfolding hinge driven by a volute spiral spring can generate the large unfolding angular speed, and locking impact of the unfolding hinge is caused. A hinge shaft is sleeved with two lug holes of a male hinge, a female hinge can be rotatably arranged on the hinge shaft in a sleeved mode, a compressing rod spring and a locking rod are both sleeved with a stud, the inner end of the volute spiral spring is arranged at the lower end of the hinge shaft in a sleeved mode, the outer end of the volute spiral spring is fixedly embedded on an adapter rod, a large gear shaft is connected with an adapter head, a small gear shaft is connected with and stretches out of a top plate, a crank is arranged on the small gear shaft in a sleeved mode, one end of a crank shaft is connected with the crank, the other end of the crank shaft is connected with one end of a rocker rod, the other end of the rocker rod is connected with a rocker rod shaft, a sliding block is arranged on the rocker rod shaft in a penetrating mode, two spring rods are arranged on the two sides in a spring cylinder respectively, and the sliding block is arranged between the two spring rods in the spring cylinder. The reduction mechanism is used for a space unfolding mechanism.

Description

technical field [0001] The invention relates to a deceleration mechanism for an unfolding hinge, in particular to a deceleration mechanism for an unfolding hinge based on a spring and a link mechanism. Background technique [0002] 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 source, male hinge, female hinge, hinge shaft and locking device, in which the male hinge and the female hinge are respectively connected to the parts to be unfolded, and can rotate around the hinge shaft, in order to increase rigidity and reduce weight And to increase reliability, the driving source of most unfolding hinges is a scroll spring. When the space deployment mechanism is on t...
