Abstract

The invention belongs to the technical field of aerospace spaceborne antennas and particularly relates to an unfolding release device of a rod antenna. According to the technical scheme, the unfolding release device comprises the rod antenna (3), a compression release mechanism (2) and an unfolding locking mechanism (1); the compression release mechanism (2) comprises an installation base (201), a compression base assembly (202), a swing frame (203), an installation frame (204), a limiting supporting plate (205), a locking reed (206), a compression screw (207) and a pyrotechnic cutter (209); the unfolding locking mechanism (1) comprises an installation frame (101), a fixed hinge support (102), a volute spring (103), a limiting block (104), a locking leaf spring (105) and a rotating hinged head (106). According to the unfolding release device of the rod antenna, the rod antenna (3) can be unfolded to a fixed angle and can be effectively locked before and after the release.

Description

technical field [0001] The invention belongs to the technical field of aerospace satellite-borne antennas, and in particular relates to a deploying device for a rod-shaped antenna. Background technique [0002] With the rapid development of space technology in recent years, the space deployment technology of spaceborne antennas has been more and more widely used. There are mainly motor drive, air pressure drive, and spring drive to drive the spaceborne antenna deployment device. The motor and air pressure drive have a relatively large additional mass of the mechanism itself, and the structure tends to be complicated, which brings a lot of pressure on the satellite's lightweight and reduces the The reliability of the institution's work. The mechanism is light in weight, simple in structure, reliable in operation, and strong in adaptability to the environment, which is one of the development directions of spaceborne antenna deployment devices.
