Title:
DOWNWARD INCLINATION ANGLE ADJUSTING APPARATUS FOR ANTENNA AND ANTENNA
Document Type and Number:
WIPO Patent Application WO/2021/227563
Kind Code:
A1
Abstract:
Provided are a downward inclination angle adjusting apparatus for an antenna and the antenna, comprising a transmission module and a motor module which are detachably connected to each other. The transmission module comprises a fixing structure, a shifting assembly, and multiple transmission assemblies. The shifting assembly comprises a driving gear, a driven gear, a shifting gear disc, and a shifting gear shaft; each transmission assembly comprises a transmission gear, a transmission screw rod, a transmission nut, and a transfer gear. When rotating, the shifting gear shaft drives the shifting gear disc to perform a circular motion, and further drives the driven gear on the shifting gear disc to perform a planetary motion, so that the driven gear is selectively engaged with one of the transfer gears; when rotating, the driving gear sequentially drives the driven gear, the transfer gear, the transmission gear, and the corresponding transmission screw rod, which are engaged with each other, to rotate, so that the corresponding transmission nut performs a straight line motion along the transmission screw rod for electronic speed control. Thus, mounting and detachment of the downward inclination angle adjusting apparatus of the present application are fast, and the volume of the antenna can be reduced, thereby facilitating the antenna layout and reducing the manufacturing cost.
