It is increasing, while minimum is accomplished in the interference between requiring different websites or even between the different sectors of same site, that is, realize
The minimum of maximization and the interference of network capacity.This purpose is realized, generally using antenna downwards bevel beam angle in adaptation stations
Mode realize.
In the two ways mechanical tilt and electrical tilt at adjustment downwards bevel beam angle, electrical tilt is with the obvious advantage, is to work as
Preceding main flow and the development trend in future.The control at electrical tilt angle is mainly divided to built-in and external two major class, wherein built-in control
It is again the main flow of current and future.The built-in control of electrical tilt mainly has two ways：A kind of mode is by single slave antenna
The a set of driving of each beam configuration and control system, realize regulation.When number of beams is more, this scheme is relatively costly, account for

The one side with unilateral bearing in face of base illustrates the work of the angle control that has a down dip of the invention as front below
Principle.
When input shaft 21 is to rotate clockwise, driving gear (including upper driving gear 23 and lower driving gear 22) up time
Pin is rotated, and lower planetary gear 31 rotates counterclockwise, and then drives the lower ring gear 35 being engaged with and affixed with lower ring gear 35
The inner ring of 4th unilateral bearing 51 is rotated counterclockwise, but the inner ring of the 4th unilateral bearing 51 can not be rotated counterclockwise with respect to outer ring, lock
Only descend the position of ring gear 35 so that lower planetary gear 31 is public clockwise along the track that lower ring gear 35 is limited around lower driving gear 22
Turn, at the same time, lower planetary gear 31 drives descending carrier 33 and threeth unilateral bearing 52 inner ring affixed with descending carrier 33 suitable
Hour hands are rotated, so as to perform the selection handover operation to output shaft 41；Upper planet wheel 32 is rotated counterclockwise, so as to drive nibble therewith
The upper ring gear and the inner ring of the second affixed therewith unilateral bearing 53 for closing are rotated counterclockwise, due to the second unilateral bearing 53 and the
The inner ring rotation direction of four unilateral bearing 51 is conversely, its inner ring can be with respect to outer ring rotating, at the same time, because up carrier is by first
The lock position of unilateral bearing 54 and can not rotate so that upper planet wheel is rotated around own torque, realizes pair being engaged with upper planet wheel
Output shaft rotation output torque.
Similarly, when input shaft 21 is to rotate counterclockwise, lower planetary gear 31 drives the input shaft 41 being engaged with to rotate
Output torque, in the process, upper planet wheel 32 switches the output shaft with selecting position around the revolution of upper driving gear 23.
It is understood that, output shaft of the invention 41 is engaged setting with lower planetary gear 31, upper planet wheel 32 so that when it
In a planetary gear perform handover operation when, another planetary gear order about be engaged with an output shaft rotation output turn
Square.Due to realizing the control of rotation direction, the power transmission response of the angle control that has a down dip of the invention using unilateral bearing
Speed is fast, efficiency high, and controls more accurate.Simultaneously as corresponding asessory shaft need not be set, the body of the control device
Product is smaller, and structure is more compact, is conducive to reducing the volume of control device, beneficial to antenna miniaturization.
Moreover, it relates to a kind of antenna (not shown) using the above-mentioned angle control that has a down dip, including many
Individual phase shifter, the output shaft correspondence is connected with the phase shifter.Because the angle control volume that has a down dip of the invention is smaller, have
Beneficial to the miniaturization of antenna；Because the above-mentioned angle control control accuracy that has a down dip is high so that Downtilt regulation of the invention
More convenient, accurate, radiation index is also more excellent.
The above is only some embodiments of the invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
