Low-Earth Orbit Satellite Antenna Mount for UAVs

Abstract

This invention provides a low-Earth orbit (LEO) satellite antenna bracket for unmanned aerial vehicles (UAVs), mounted on the UAV to support the LEO satellite antenna. It includes a support base, at least one connecting arm, and at least one antenna mounting bracket. The connecting arm has a hollow internal structure defining a heat dissipation channel, and its surface has airflow guiding holes and an exhaust port communicating with the channel. The at least one antenna mounting bracket is connected to the side of the LEO satellite antenna. Thus, during UAV flight, external airflow can be introduced through the airflow guiding holes, guided through the heat dissipation channel, and exhausted through the exhaust port to the bottom of the LEO satellite antenna for air cooling, achieving extreme lightweight design. Furthermore, the sliding groove design allows for adaptation to different antenna sizes and fine adjustment of the center of gravity.

Claims

1. A low-Earth orbit (LEO) satellite antenna bracket for a drone, mounted on a drone to support a LEO satellite antenna, the antenna bracket comprising: a support base mounted on the drone; at least one connecting arm connected to the support base, the at least one connecting arm having a hollow structure defining a heat dissipation channel, and at least one airflow cooling hole on the surface of the at least one connecting arm communicating with the heat dissipation channel; and at least one antenna mounting base disposed at one end of the at least one connecting arm away from the support base, the at least one antenna mounting base being connected to at least one side of the LEO satellite antenna to support the LEO satellite antenna; wherein... At least one air outlet is provided on the upper surface of at least one connecting arm. The air outlet is connected to the airflow cooling channel so that the external airflow introduced by the airflow cooling hole during the flight of the UAV is guided to flow through the bottom of one of the low-orbit satellite antennas for air cooling.

2. The low-Earth orbit satellite antenna bracket for an unmanned aerial vehicle as described in claim 1, wherein, The at least one connecting arm further has at least one groove, and the at least one antenna mounting base is slidably disposed in the at least one groove. The at least one antenna mounting base can be positioned and locked in a specific position of the at least one groove by a locking fastener, so as to perform modular installation for low-orbit satellite antennas of different sizes and fine-tune the overall center of gravity of the UAV when carrying the low-orbit satellite antenna.

3. The low-Earth orbit satellite antenna bracket for an unmanned aerial vehicle as described in claim 1, wherein, The hollow structure of the at least one connecting arm further includes at least one reinforcing rib, which is provided to provide support rigidity and does not obstruct the airflow cooling channel.

4. The low-Earth orbit satellite antenna bracket for an unmanned aerial vehicle as described in claim 1, wherein, The surface of at least one of the connecting arms is further provided with at least one weight-reducing hole, which is connected to the hollow structure to reduce the weight of the support.

5. The low-Earth orbit satellite antenna bracket for an unmanned aerial vehicle as described in claim 1, wherein, The at least one airflow cooling hole is disposed on one surface of the at least one antenna mounting base, or on one surface of the at least one connecting arm.

6. The low-Earth orbit satellite antenna bracket for a drone as described in claim 1 further includes at least one vibration damping element disposed between the support base and the at least one connecting arm, or disposed between the at least one connecting arm and the low-Earth orbit satellite antenna, for reducing the transmission of vibrations from the drone to the low-Earth orbit satellite antenna.

7. The low-Earth orbit satellite antenna mount for an unmanned aerial vehicle as described in claim 1, wherein, The low-orbit satellite antenna system is an array antenna plate.
