Problems solved by technology
Multiple sets of drive motors have the disadvantages of large space occupation, heavy weight and high cost
In response to the above problems, there is also a scheme in the industry to control multiple output shafts through one motor. For example, Chinese patent CN208028214U discloses an antenna phase shifter transmission device. The structure of the device is relatively complicated, the manufacturing cost is high, and the space utilization rate is low.
[0004]
In summary, there are many problems in the actual use of existing methods, so it is necessary to improve

The invention is applicable to the technical field of antenna equipment and provides a device for adjusting adownward inclination angle of a multi-frequency electrically-tunable antenna. The device comprises a transmission module and a driving module. The transmission module is provided with a one-way transmission mechanism, a power transmission mechanism and at least two power conversion mechanisms which are in key connection in sequence. The power transmission mechanism is provided with a driving gear, a reversing gear and at least two driven gear sets. The power conversion mechanisms are intransmission connection with the driven gear sets in a one-to-one correspondence mode. The driving module is in positive and negative rotation transmission connection with the one-way transmission mechanism; and the driving module rotates reversely to drive a reversing gear to rotate around the driving gear to be connected with one driven gear set in a meshed mode, and the driving module rotatesforwards to drive the driving gear to rotate so as to indirectly transmit antenna downward inclination angle adjustment corresponding to the driven gear set meshed with the reversing gear. Therefore,only a single motor is needed for driving, the structure is simple and compact, a space utilization rate can be increased, and cost is reduced.
Description
technical field [0001] The invention relates to the technical field of antenna equipment, in particular to a device for adjusting the downtilt angle of a multi-frequency electric adjustable antenna. Background technique [0002] Electrically adjustable antenna is a widely used antenna form. During the application process of the antenna, it is necessary to adjust the downtilt angle of the base station communication antenna reasonably, so as to facilitate the later network maintenance and optimization. By adjusting the phase shifter, a key component of the antenna, the antenna feed network is continuously adjusted, and the phase of each oscillator in the antenna array is continuously changed, thereby realizing continuous adjustment of the antenna electrical downtilt angle. [0003] The phase shifter in the antenna is driven by a transmission device. In the traditional phase shifter transmission device, most of the phase shifter control devices are controlled by a motor. For e...
