Abstract

The invention discloses an unfolding hinge deceleration mechanism based on a spring and link mechanism, which relates to an unfolding hinge deceleration mechanism. The present invention aims to solve the problem that the unfolding end of the unfolding hinge driven by the scroll spring generates a large unfolding angular velocity, which causes the locking impact of the unfolding hinge. The hinge shaft of the present invention is set in the two ear holes of the male hinge, the female hinge is rotatably set on the hinge shaft, the pressure bar spring and the locking bar are both set in the stud, and the inner end of the scroll spring is set in the lower end of the hinge shaft. The outer end of the scroll spring is fixedly inlaid on the adapter rod, the large gear shaft is connected with the adapter, the pinion shaft is connected and extends out of the top plate, the crank fits on the pinion shaft, one end of the crank shaft is connected with the crank, and the other end of the crank shaft One end is connected with one end of the rocker, the other end of the rocker is connected with the rocker shaft, the slider is passed on the rocker shaft, the two spring rods are respectively located on both sides of the spring barrel, and the slider is located at the two between the spring bars. The invention is used in 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...
