Description

Technical Field

[0001] The utility model relates to the technical field of fixed-wing unmanned aerial vehicles, and particularly relates to an enhanced antenna for fixed-wing unmanned aerial vehicle communication. Background Technique

[0002] A fixed-wing unmanned aerial vehicle is an unmanned aircraft that generates lift through wings fixed to the fuselage. They are similar to traditional airplanes but do not require a pilot to operate on board. The flight principle of fixed-wing unmanned aerial vehicles is based on aerodynamics, mainly relying on the shape and angle of the wings to generate lift, and at the same time using an engine or an electric drive system to provide thrust. The communication antenna of the unmanned aerial vehicle ensures the stability of the data link between the unmanned aerial vehicle and the ground control station, and transmits flight data, sensor information, and mission-related instructions.

[0003] However, in the current prior art, in order to avoid signal interference and ensure the signal reception effect, the communication antennas of some fixed-wing unmanned aerial vehicles are still installed on the top of the unmanned aerial vehicle. However, the antennas installed on the top of the unmanned aerial vehicle are generally in a bundle structure. Although the aperture is small and it will not cause an impact during normal flight, when the unmanned aerial vehicle enters high-speed flight, the air will be split when passing through the antenna, which will thus have a certain impact on the flight angle of the unmanned aerial vehicle and cause the flight angle to deviate. Content of the Utility Model

[0004] The purpose of the utility model is to provide an enhanced antenna for fixed-wing unmanned aerial vehicle communication to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] An enhanced antenna for fixed-wing unmanned aerial vehicle communication, including a base and an antenna column. An installation frame is arranged on the outer wall of the antenna column. An auxiliary component for assisting during high-speed flight of the unmanned aerial vehicle is arranged inside the installation frame. The auxiliary component includes a cavity arranged inside the installation frame. A soft rubber layer is arranged on the inner wall of the cavity. Support seats are arranged at both ends of the inner wall of the cavity. Extension plates are arranged on the inner walls of both support seats. Positioning grooves are arranged on the outer walls of the extension plates and the support seats. A column is arranged inside the extension plate.

[0007] As a preferred scheme of the utility model, the base is connected to the top of the fixed-wing unmanned aerial vehicle through bolts. The antenna column is rotationally connected to the base through a connecting shaft, and the connecting shaft of the antenna column is electrically connected to the ground control center.

[0008] As a preferred scheme of the utility model, the installation frame is located on one side of the antenna column and is integrally formed with the outer wall of the antenna column. The cavity extends into the antenna column, and the soft rubber layer is inlaid and connected with the inner wall at the outlet of the cavity.

[0009] As a preferred solution of the present utility model, the two support seats are respectively installed at both ends of the inner wall of the cavity through bolts, the extension plate is slidably connected with the support seat through a positioning groove, and the column is located between the two extension plates and is slidably connected with the extension plate through a positioning groove.

[0010] As a preferred solution of the present utility model, the support seat and the column can slide and stagger through the extension plate, and when the column slides, it abuts against the soft rubber layer on the inner wall of the cavity and pushes the soft rubber layer to deform and extend out of the cavity.

[0011] As a preferred solution of the present utility model, both the column and the extension plate are electrically connected to the control center on the ground, and when the flight speed of the fixed-wing unmanned aerial vehicle reaches the set value, the sliding between the column and the extension plate is controlled.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: In response to the problems raised in the background art, this application adopts an auxiliary component. By accommodating the column inside the antenna column, the antenna is in a normal state during normal conditions, reducing the impact on normal flight. When the flight speed of the fixed-wing unmanned aerial vehicle reaches the set value, the column inside the antenna column is controlled to slide and extend outwards in the mounting frame, and the soft rubber layer inside the mounting frame is pushed to deform and extend out, thereby increasing the width of the antenna column. Moreover, the antenna column can be rotatably connected to the base, receiving the turning signal of the unmanned aerial vehicle and rotating synchronously during high-speed flight, and using the width of the antenna column as a turning wing for auxiliary use.

[0013] The present utility model realizes increasing the width of the antenna column when the fixed-wing unmanned aerial vehicle is flying at high speed, using it as a turning wing to assist the unmanned aerial vehicle in turning, reducing the impact caused by the antenna column during the high-speed flight of the unmanned aerial vehicle while assisting the flight of the unmanned aerial vehicle, and improving the stability of the unmanned aerial vehicle during high-speed flight.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention.

[0021] Embodiment

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: an enhanced antenna for fixed-wing UAV communication, including a base 1 and an antenna column 2. An installation frame 3 is arranged on the outer wall of the antenna column 2. An auxiliary component for assisting during the high-speed flight of the UAV is arranged inside the installation frame 3. The auxiliary component includes a cavity 301 arranged inside the installation frame 3, which is used to store and accommodate the support base 4 and the column 6 in a normal state, ensuring the shape of the antenna column 2 (when the fixed-wing UAV flies at a low speed or a normal speed, since the multi-faceted surfaces of the antenna column 2 are arc-shaped structures, the impact on flight can be ignored).

[0023] A soft rubber layer 302 is arranged on the inner wall of the cavity 301. The soft rubber layer 302 can seal the cavity 301 and deform when pressed. Support bases 4 are arranged at both ends of the inner wall of the cavity 301, which are used to position the positions and angles of the extension plate 401 and the column 6. Extension plates 401 are arranged on the inner walls of the two support bases 4. Both the support base 4 and the column 6 can slide with the extension plate 401, resulting in dislocation, so that the column 6 extends outside the cavity 301. Positioning grooves 5 are arranged on the outer walls of the extension plate 401 and the support base 4, which are used to position the angle of the column 6 when it moves. A column 6 is arranged inside the extension plate 401. When the fixed-wing UAV starts to fly at a high speed and reaches the set value, a signal is sent to control the column 6 and the extension plate 401 to slide and intersect with the support base 4. At the same time, when the column 6 slides and abuts against the soft rubber layer 302 and pushes it, it deforms and extends out of the cavity 301, increasing the width of the antenna column 2. At the same time, the antenna column 2 receives the signal sent from the ground and rotates with the base 1 to assist the fixed-wing UAV to turn.

[0024] In this embodiment, all electrical components are controlled by a conventional controller.

[0025] Embodiment, please refer to Figures 1-5, the base 1 is connected to the top of the fixed-wing UAV through bolts. The antenna column 2 is rotatably connected to the base 1 through a connecting shaft, and the connecting shaft of the antenna column 2 is electrically connected to the ground control center. The mounting bracket 3 is located on one side of the antenna column 2 and is integrally formed with the outer wall of the antenna column 2. The cavity 301 extends into the antenna column 2. The soft rubber layer 302 is inlaid and connected with the inner wall at the outlet of the cavity 301. The two support seats 4 are respectively installed at both ends of the inner wall of the cavity 301 through bolts. The extension plate 401 is slidably connected to the support seat 4 through the positioning groove 5. The upright column 6 is located between the two extension plates 401 and is slidably connected to the extension plate 401 through the positioning groove 5. The support seat 4 and the upright column 6 can slide and stagger through the extension plate 401. When the upright column 6 slides, it abuts against the soft rubber layer 302 on the inner wall of the cavity 301 and pushes the soft rubber layer 302 to deform and protrude from the cavity 301. Both the upright column 6 and the extension plate 401 are electrically connected to the ground control center, and when the flight speed of the fixed-wing UAV reaches the set value, the sliding between the upright column 6 and the extension plate 401 is controlled. During use, first, when the flight speed of the fixed-wing UAV reaches the set value, the PLC controller is used to control the sliding of the extension plate 401 and the support seat 4, drive the upright column 6 to move out of the cavity 301 and abut against the soft rubber layer 302, and push it to protrude from the cavity 301 to increase the width of the antenna column 2 (switch the antenna column 2 to the second form). Then, when the ground control center controls the UAV to turn during flight, the corresponding rotation of the antenna column 2 and the base 1 is synchronously controlled to assist the UAV in turning.

[0026] The working process of the present utility model: During use, first, when the flight speed of the fixed-wing UAV reaches the set value, the PLC controller is used to control the sliding of the extension plate 401 and the support seat 4, drive the upright column 6 to move out of the cavity 301 and abut against the soft rubber layer 302, and push it to protrude from the cavity 301 to increase the width of the antenna column 2 (switch the antenna column 2 to the second form). Then, when the ground control center controls the UAV to turn during flight, the corresponding rotation of the antenna column 2 and the base 1 is synchronously controlled to assist the UAV in turning. The present utility model realizes increasing the width of the antenna column when the fixed-wing UAV is flying at high speed, making it serve as a steering wing to assist the UAV in turning, reducing the influence caused by the antenna column during the high-speed flight of the UAV while assisting the UAV in flying, and improving the stability of the UAV during high-speed flight.

[0027] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
