Problems solved by technology
Multiple sets of driving motors take up a lot of space, it is complicated to connect with the transmission device, the installation and disassembly are complicated, and it is very inconvenient to use
In addition, if the motor fails, the entire antenna needs to be removed for maintenance, which not only affects the use of the antenna but also costs a lot and reduces work efficiency
[0005]
In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

The invention provides a downward inclination angle adjusting device of an antenna and the antenna. The downward inclination angle adjusting device comprises a transmission module and a motor module which are detachably connected with each other. The transmission module comprises a fixing structure, a gear shifting assembly and a plurality of transmission assemblies. The gear shifting assembly comprises a driving gear, a driven gear, a gear shifting gear disc and a gear shifting gear shaft. Each transmission assembly comprises a transmission gear, a transmission screw, a transmission nut and an adapter gear. When the gear-shifting gear shaft rotates, the gear-shifting gear disc is driven to do circular motion, and then the driven gear on the gear-shifting gear disc is driven to do planetary motion, so that the driven gear is selectively meshed with one of the switching gears. And when the driving gear rotates, the driven gear, the switching gear, the transmission gear and the corresponding transmission screw which are meshed with one another are sequentially driven to rotate, so that the corresponding transmission nut linearly moves along the transmission screw to perform electronic speed control. Therefore, the downward inclination angle adjusting device is quick to mount and dismount, the size of the antenna can be reduced, the antenna layout is facilitated, and the manufacturing cost is reduced.
Description
technical field [0001] The invention relates to the technical field of mobile communication base station antennas, in particular to an antenna downtilt angle adjustment device and the antenna. Background technique [0002] As the terminal of the mobile communication network, the mobile antenna carries the dual functions of electromagnetic wave transmission and reception, that is, the carrier of mobile communication signal transmission, and its application effect directly determines the quality of the mobile communication network. Among them, the electronically adjustable antenna is a mobile antenna that electronically adjusts the downtilt angle. Because the electronically adjustable antenna can reduce call loss, reduce interference, and adjust the downtilt angle with high accuracy, it is widely used in mobile communication base stations. [0003] In the mobile communication system, in order to optimize the coverage of the wireless signal in the service area and to suppress t...
