Abstract

The invention discloses a large-caliber umbrella antenna deployment mechanism which comprises a driver, a bevel gear set, a support, screw rods, sliders, connecting rods, rib assemblies, springs and stop pins. The support is a hollow cylinder structure. One end of the support is equipped with a driver for providing power, and a plurality of screw rods for transmitting power are arranged inside thesupport. The driver is connected to the screw rods through the bevel gear set, the screw rods are equipped with the sliders which are only in translational motion along the axial directions of the screw rods. The other end of the support is equipped with the rib assemblies for assembling an antenna, the rib assemblies are hinged to the sliders through the connecting rods, and the stop pins for locking the rib assemblies are pressed and installed at the outer side of the support through the springs. Through the cooperation of the driver, the bevel gear set, the support, the screw rods, the sliders, the connecting rods, the rib assemblies, the springs and the stop pins, the synchronous deployment of an umbrella antenna is achieved, a deployment torque is enhanced, a device volume is reduced, the safe and reliable deployment process is ensured, and shortcomings of a traditional umbrella antenna deployment mechanism are made up.
