US 2026/0302610 A1 · DOUBLE-AXIS ROTATING ANTENNA STRUCTURE

Abstract

A double-axis rotating antenna structure includes a base, a yaw rotating frame, an antenna assembly, a pitch rotating linkage assembly and a driving mechanism. The base includes a central gear. The antenna assembly is pivotally disposed at the yaw rotating frame and includes an antenna disc. The pitch rotating linkage assembly is connected to the antenna assembly. The driving mechanism is disposed at the yaw rotating frame and includes a worm shaft, a motor and a planet gear. The worm shaft is connected to the pitch rotating linkage assembly. The motor is connected to and drives the worm shaft. The planet gear is engaged with the central gear and is driven by the worn gear. The motor rotates the worm shaft to actuate the pitch linkage assembly to pitch the antenna disc and drive the planet gear to yaw the antenna disc.

Dependent claims

A double-axis rotating antenna structure, comprising:

a base, comprising a central gear;
a yaw rotating frame, movably disposed at the base and yawing relative to the base;
an antenna assembly, pivotally disposed at the yaw rotating frame and comprising an antenna disc;
a pitch rotating linkage assembly, one end thereof connected to the antenna assembly;
and
a driving mechanism, disposed at the yaw rotating frame and comprising:
a worm shaft, connected to another end of the pitch rotating linkage assembly and rotating about a first axis;
a motor, connected to and driving the worm shaft;
and
a planet gear, engaged with the central gear and driven by the worm shaft to rotate about a second axis, the second axis being orthogonal to the first axis;
wherein the motor rotates to drive the worm shaft to actuate the pitch rotating linkage assembly to pitch the antenna disc, and simultaneously drives the planet gear to move circumferentially along the central gear to yaw the antenna disc.
