In the case of some obstacles, such as interference sources between the aircraft and the control terminal or obstacles blocking the communication signal between the two, the communication efficiency or communication distance between the aircraft and the control terminal will be significantly affected, thereby affecting the communication effect between the two.

In some embodiments, the power member 23 can be, but is not limited to, a power motor that can generate power for the blades 22 to rotate.

[0032] In some embodiments, the antenna assembly 30 may include a directional antenna 31, a transmission assembly 32, a driver 33, an angle detection sensor 34, and a controller 35 (see Figure 1 ).

[0033] The directional antenna 31 is used to transmit and receive wireless signals in a specific direction. In some embodiments, the directional antenna 31 may be, but is not limited to, a directional high-gain antenna, which can focus electromagnetic waves to radiate or receive in a specific direction, and can be suitable for long-distance communication or communication in a specific direction of the aircraft 100 to ensure communication efficiency and signal quality.

[0034] In some embodiments, the directional antenna 31 may include a radiator 312 and a carrier 314. The radiator 312 is disposed on the carrier 314, and the radiator 312 may include a polarization plane 3122 and a connection point 3124. The polarization plane 3122 may be a radiation plane for the directional antenna 31 to transmit and receive wireless signals. The connection point 3124 is disposed at one end of the radiator 312, and is used to connect to other components to achieve conduction of current or signals.

[0035] The carrier 314 may be provided with a receiving groove 3142 for receiving the radiator 312. A connecting portion 3144 is provided at one end of the carrier 314. The connecting portion 3144 may be cylindrical and connected to the transmission assembly 32. The connecting portion 3144 may realize the overall rotation of the directional antenna 31.

[0036] Please also read Figure 2 , Figure 3 and Figure 4 The transmission assembly 32 is connected to the directional antenna 31, and is used to drive the directional antenna 31 to rotate. In some embodiments, the transmission assembly 32 may include a first transmission member 322 and a second transmission member 324. The first transmission member 322 is meshedly connected with the second transmission member 324.

The slip ring 316 is rotatably received in the circular hole portion 3244. When the second transmission member 324 drives the directional antenna 31 to rotate, the slip ring 316 is rotatably received in the circular hole portion 3244 to prevent the wire 318 from being twisted or entangled due to rotation.

[0039] The driving member 33 is connected to the first transmission member 322, and is used to drive the first transmission member 322 to rotate. In some embodiments, the driving member 33 can be, but is not limited to, a driving motor, which can generate a rotational driving force. The driving member 33 includes a rotating shaft 332, which is arranged at one end of the driving member 33, and the rotating shaft 332 is fixedly connected to the angle detection sensor 34 and the first transmission member 322, and is used to drive the angle detection sensor 34 and the first transmission member 322 to rotate synchronously. In some embodiments, the rotating shaft 332 can be roughly D-shaped, and the angle detection sensor 34 and the first transmission member 322 can be respectively provided with D-shaped holes, and the rotating shaft 332 can pass through the D-shaped holes of the angle detection sensor 34 and the first transmission member 322 in sequence to achieve a fixed connection between the rotating shaft 332, the angle detection sensor 34 and the first transmission member 322.

[0040] The angle detection sensor 34 is connected between the driving member 33 and the first transmission member 322, and can rotate synchronously with the rotating shaft 332 and the first transmission member 322. The angle detection sensor 34 is used to detect the current direction or angle of the pointing antenna 31. In some embodiments, the angle detection sensor 34 can be connected to the controller 35 through a wire (not shown), and detect the current direction or angle of the pointing antenna 31 according to a preset frequency band, and transmit the detection data to the controller 35 in real time.

[0041] The controller 35 can be set in the body 10, and can be used to obtain information of other electronic devices, such as obtaining positioning information of other electronic devices, and can obtain the current direction or angle of the directional antenna 31 detected by the angle detection sensor 34, and can control the driving member 33 to drive the directional antenna 31 to rotate to a preset direction.

[0042] In some embodiments, the antenna assembly 30 may further include a bracket 36 and a cover 37 .

[0043] The bracket 36 can be used to accommodate the transmission assembly 32, the driving member 33 and the angle detection sensor 34. The bracket 36 can include a receiving disk 362, a first receiving tube 364 and a second receiving tube 366. The receiving disk 362 is roughly in the shape of a hollow disk, and can be used to accommodate the first transmission member 322, the angle detection sensor 34 and the gear 3242 of the second transmission member 324. The first receiving tube 364 and the second receiving tube 366 are adjacently arranged on the receiving disk 362, and the first receiving tube 364 is roughly in the shape of a hollow cylinder, and can be used to accommodate the driving member 33. In some embodiments, the driving member 33 is accommodated in the first receiving tube 364, and the rotating shaft 332 extends into the receiving disk 362, and the angle detection sensor 34 and the first transmission member 322 are connected in the receiving disk 362. The second receiving tube 366 is roughly in the shape of a hollow cylinder, and can be used to accommodate the circular hole portion 3244 and the fixing portion 3246 of the second transmission member 324. In some embodiments, the circular hole portion 3244 of the second transmission member 324 can extend from the second receiving tube 366 into the receiving tray 362, and connect the gear 3242 in the receiving tray 362, and the fixing portion 3246 can extend from the second receiving tube 366 and connect the connecting portion 3144 of the carrier 314. In some embodiments, the first receiving tube 364 and the second receiving tube 366 are disposed adjacent to each other, so that the driving member 33 and the directional antenna 31 are also disposed adjacent to each other. In some embodiments, the bracket 36 can be received in the base 21 of the arm 20.

[0044] The cover 37 can be used to accommodate the directional antenna 31 and is connected to the first receiving tube 364 and the second receiving tube 366 of the bracket 36, so that the cover 37 and the bracket 36 can accommodate the directional antenna 31, the transmission assembly 32, the driving member 33 and the angle detection sensor 34 for physical protection.

[0045] During the flight of the aircraft 100, the antenna assembly 30 can adjust the directional antenna 31 to rotate to a preset direction according to actual needs, so that the directional antenna 31 transmits and receives wireless signals in the preset direction. Specifically, the current direction or angle of the directional antenna 31 is detected by the angle detection sensor 34, and the controller 35 obtains the current direction or angle of the directional antenna 31 detected by the angle detection sensor 34. The controller 35 can control the driving member 33 to drive the first transmission member 322 according to actual needs, such as the preset direction, and the first transmission member 322 drives the second transmission member 324, and the second transmission member 324 drives the directional antenna 31 to rotate to the preset direction, so that the directional antenna 31 transmits and receives wireless signals in the preset direction, thereby improving the communication effect of the directional antenna 31 in the preset direction. It can be understood that the preset direction can be the target direction for the aircraft 100 to communicate, for example, in this preset direction, the aircraft 100 communicates with the target device or terminal for communication.

[0046] Please also read Figure 5 and Figure 6 , an embodiment of the present application provides an aircraft system, including an aircraft 100 and a control terminal 200. The aircraft 100 and the control terminal 200 can communicate wirelessly. In some embodiments, the control terminal 200 can be a remote control device that matches the aircraft 100 and can be used to remotely control the aircraft 100. The control terminal 200 can send instructions to the aircraft 100 by wireless transmission, thereby controlling the movement of the aircraft 100 and the operation of other devices on the aircraft 100.

[0047] In some embodiments, the control terminal 200 realizes wireless communication signals or wireless transmission by installing a directional antenna 210. In some embodiments, the directional antenna 210 of the control terminal 200 may have substantially the same structure and function as the directional antenna 31 of the aircraft 100, that is, the directional antenna 210 is also used to transmit and receive wireless signals in a specific direction, and has a rotatable function, so that the directional antenna 210 can be rotated to a preset direction according to actual needs. It can be understood that during the flight of the aircraft 100, the position of the aircraft 100 can change in real time or intermittently, and the control terminal 200 can be held on the ground by a user or operator, that is, the relative position or relative angle between the aircraft 100 and the control terminal 200 will change in real time or intermittently, so it is necessary to dynamically adjust the directional antenna 31 of the aircraft 100 to rotate to a preset direction, such as toward the control terminal 200, and dynamically adjust the directional antenna 210 of the control terminal 200 to rotate to a preset direction, such as toward the current position of the aircraft 100.

[0048] In some embodiments, the aircraft 100 may further include a satellite positioning receiving antenna 38 for receiving positioning information of other target devices or terminals, such as receiving positioning information of the control terminal 200. The control terminal 200 may further include a satellite positioning receiving antenna 220 for receiving positioning information of other target devices or terminals, such as receiving positioning information of the aircraft 100.

[0049] In some embodiments, the aircraft 100 and the control terminal 200 can transmit their respective positioning information to each other. After the aircraft 100 obtains the positioning information of the control terminal 200, the controller 35 calculates the direction angle A of the control terminal 200 relative to the pointing antenna 31. The direction angle A can be the direction angle toward the control terminal 200, and obtains the current direction angle B of the pointing antenna 31 detected by the angle detection sensor 34, and calculates whether the direction angle A is the same as the direction angle B. If the direction angle A is different from the direction angle B, the control drive member 33 drives the first transmission member 322, the first transmission member 322 drives the second transmission member 324, and the second transmission member 324 drives the pointing antenna 31 to rotate to the direction angle A, so that the pointing antenna 31 is at the direction angle A, that is, the direction angle toward the control terminal 200, to transmit and receive wireless signals, thereby improving the communication effect between the pointing antenna 31 and the control terminal 200. Similarly, the control terminal 200 can control the directional antenna 210 to rotate toward the aircraft 100, so that the directional antenna 210 transmits and receives wireless signals in the direction angle toward the aircraft 100, thereby improving the communication effect between the directional antenna 210 and the aircraft 100.

[0050] In some embodiments, since the position of the aircraft 100 changes dynamically during flight, the aircraft 100 and the control terminal 200 adjust their respective directional antennas to rotate toward each other and refresh according to a preset frequency, thereby dynamically adjusting the communication effect between the aircraft 100 and the control terminal 200.

[0051] It can be understood that when the aircraft 100 and the control terminal 200 dynamically adjust their respective directional antennas to turn toward each other, the directional antennas of the aircraft 100 and the control terminal 200 can be in a better signal transmission and reception direction angle, which can increase the communication distance between the aircraft 100 and the control terminal 200, increase the communication transmission power in this direction angle, and improve the communication effect.

[0052] In other embodiments, when there is an interference source or obstacle between the aircraft 100 and the control terminal 200, the aircraft 100 can calculate the optimal azimuth angle by combining the direction angle A and the direction angle B through the controller 35 to reduce the impact of the interference source or obstacle and ensure the communication effect.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them. In the actual application process, the entire content of the technical solutions described in any embodiment of the present application can be implemented, or some content can be added, or some content can be deleted, or some content can be changed / replaced. Although the present application is described in detail with reference to the preferred embodiments, it should be understood by those of ordinary skill in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
