Description

Antenna electric lodging device

technical field

Background technique

With the development of modern information technology, more and more wireless communication devices are installed on special vehicles such as emergency rescue, disaster relief, and civil air defense. Multiple antennas often need to be installed on the top of a special vehicle. At the same time, the requirements for real-time information grasping, real-time information transmission, in-movement command and driving passability require special vehicles to be able to control the lodging of the antenna during the driving process. How to install multiple antennas and their lodging mechanisms in the limited roof space without interfering with each other, so as to realize the antenna lodging control in motion has become a difficult problem.

At present, the vehicle-mounted antenna lodging mechanism mainly uses a linear push rod to achieve power output, and lodging control is performed on a single antenna. When there are many roof antennas, multiple lodging mechanisms need to be equipped, which is not conducive to operation and increases costs.

In view of the above situation, using single lodging to control dual antennas or multi-antennas through the linkage shaft is an effective means to solve the shortage of roof space, but the existing push rod type lodging has insufficient power and complicated structural transformation. Motors also add cost and installation space. In consideration of power, installation space, and cost, a new type of lodging mechanism must be designed to simultaneously control the lodging of two or more antennas.
